There are eight "postulates", but most of these have several parts (which are generally called assumptions in this system). Counting these parts, there are 32 axioms in this system. Amongst the postulates can be found the point-line- plane postulate, the Triangle inequality postulate, postulates for distance, angle measurement, corresponding angles, area and volume, and the Reflection postulate. The reflection postulate is used as a replacement for the SAS postulate of SMSG system.
Many attempts were made to prove the fifth postulate based on the other four, but they never succeeded. Eventually in 1829, mathematician Nikolai Lobachevsky published a description of acute geometry (or hyperbolic geometry), a geometry which assumed a different form of the parallel postulate. It is in fact possible to create a valid geometry without the fifth postulate entirely, or with different versions of the fifth postulate (elliptic geometry). If one takes the fifth postulate as a given, the result is Euclidean geometry.
George Hammond developed the postulate during his professorship at Iowa State University Hammond's postulate (or alternatively the Hammond–Leffler postulate), is a hypothesis in physical organic chemistry which describes the geometric structure of the transition state in an organic chemical reaction. First proposed by George Hammond in 1955, the postulate states that: Solomons, T.W. Graham & Fryhle, Craig B. (2004). Organic Chemistry (8th ed.). John Wiley & Sons, Inc. .
Posidonius was one of the first to attempt to prove Euclid's fifth postulate of geometry. He suggested changing the definition of parallel straight lines to an equivalent statement that would allow him to prove the fifth postulate. From there, Euclidean geometry could be restructured, placing the fifth postulate among the theorems instead.Trudeau, Richard.
The book was based on his father's thoughts and presented one of the earliest arguments for a non-Euclidean hypothesis equivalent to the parallel postulate. After reading this, Wallis then wrote about his ideas as he developed his own thoughts about the postulate, trying to prove it also with similar triangles.The Mathematics of Egypt, Mesopotamia, China, India, and Islam:A Sourcebook Victor J. Katz Princeton University Press He found that Euclid's fifth postulate is equivalent to the one currently named "Wallis postulate" after him. This postulate states that "On a given finite straight line it is always possible to construct a triangle similar to a given triangle".
Invariably the mistake was assuming some 'obvious' property which turned out to be equivalent to the fifth postulate. Eventually it was realized that this postulate may not be provable from the other four. According to this opinion about the parallel postulate (Postulate 5) does appear in print: > Apparently the first to do so was G. S. Klügel (1739-1812), a doctoral > student at the University of Gottingen, with the support of his teacher A. > G. Kästner, in the former's 1763 dissertation Conatuum praecipuorum theoriam > parallelarum demonstrandi recensio (Review of the Most Celebrated Attempts > at Demonstrating the Theory of Parallels). In this work Klügel examined 28 > attempts to prove Postulate 5 (including Saccheri's), found them all > deficient, and offered the opinion that Postulate 5 is unprovable and is > supported solely by the judgment of our senses.
He recognized that three possibilities arose from omitting Euclid's fifth postulate; if two perpendiculars to one line cross another line, judicious choice of the last can make the internal angles where it meets the two perpendiculars equal (it is then parallel to the first line). If those equal internal angles are right angles, we get Euclid's fifth postulate, otherwise, they must be either acute or obtuse. He showed that the acute and obtuse cases led to contradictions using his postulate, but his postulate is now known to be equivalent to the fifth postulate. Nasir al-Din al-Tusi (1201–1274), in his Al-risala al-shafiya'an al-shakk fi'l-khutut al-mutawaziya (Discussion Which Removes Doubt about Parallel Lines) (1250), wrote detailed critiques of the parallel postulate and on Khayyám's attempted proof a century earlier.
13 postulate that this verse refers specifically to the Temple of Solomon.
Spherical geometry obeys two of Euclid's postulates: the second postulate ("to produce [extend] a finite straight line continuously in a straight line") and the fourth postulate ("that all right angles are equal to one another"). However, it violates the other three: contrary to the first postulate, there is not a unique shortest route between any two points (antipodal points such as the north and south poles on a spherical globe are counterexamples); contrary to the third postulate, a sphere does not contain circles of arbitrarily great radius; and contrary to the fifth (parallel) postulate, there is no point through which a line can be drawn that never intersects a given line.Gowers, Timothy, Mathematics: A Very Short Introduction, Oxford University Press, 2002: pp. 94 and 98.
The state postulate is a term used in thermodynamics that defines the given number of properties to a thermodynamic system in a state of equilibrium. It is also sometimes referred to as the state principle . The state postulate allows a finite number of properties to be specified in order to fully describe a state of thermodynamic equilibrium. Once the state postulate is given the other unspecified properties must assume certain values.
Euclid gave the definition of parallel lines in Book I, Definition 23Euclid's Elements, Book I, Definition 23 just before the five postulates.Euclid's Elements, Book I Euclidean geometry is the study of geometry that satisfies all of Euclid's axioms, including the parallel postulate. The postulate was long considered to be obvious or inevitable, but proofs were elusive. Eventually it was discovered that inverting the postulate gave valid, albeit different geometries.
If the sum of the interior angles α and β is less than 180°, the two straight lines, produced indefinitely, meet on that side. In geometry, the parallel postulate, also called Euclid's fifth postulate because it is the fifth postulate in Euclid's Elements, is a distinctive axiom in Euclidean geometry. It states that, in two-dimensional geometry: > If a line segment intersects two straight lines forming two interior angles > on the same side that sum to less than two right angles, then the two lines, > if extended indefinitely, meet on that side on which the angles sum to less > than two right angles. This postulate does not specifically talk about parallel lines;non-Euclidean geometries, by Dr. Katrina Piatek-Jimenez it is only a postulate related to parallelism.
" In meaning postulate this would look like this: x MAN ≡ x HUMAN BEING 2\. "If X is a girl, then X is female." In meaning postulate this would look like this: x GIRL → x FEMALE 3\. "X is not awake, therefore X is asleep.
A geometry where the parallel postulate does not hold is known as a non-Euclidean geometry. Geometry that is independent of Euclid's fifth postulate (i.e., only assumes the modern equivalent of the first four postulates) is known as absolute geometry (or sometimes "neutral geometry").
Among all such sets, postulate a set such that no other set is smaller. Such a set can be constructed with Unrestricted Domain and an adaptation of the voting paradox to imply a still smaller set. This contradicts the postulate and so proves the theorem.
For two thousand years, many attempts were made to prove the parallel postulate using Euclid's first four postulates. A possible reason that such a proof was so highly sought after was that, unlike the first four postulates, the parallel postulate isn't self- evident. If the order the postulates were listed in the Elements is significant, it indicates that Euclid included this postulate only when he realised he could not prove it or proceed without it. Many attempts were made to prove the fifth postulate from the other four, many of them being accepted as proofs for long periods of time until the mistake was found.

Technically, Hammond's postulate only describes the geometric structure of a chemical reaction. However, Hammond's postulate indirectly gives information about the rate, kinetics, and activation energy of reactions. Hence, it gives a theoretical basis for the understanding the Bell–Evans–Polanyi principle, which describes the experimental observation that the enthalpy and rate of a similar reactions were usually correlated. Energy diagrams of SN1 reactions The relationship between Hammond's postulate and the BEP principle can be understood by considering a SN1 reaction.
Unfortunately, Hilbert's system requires 21 axioms. Other systems have used fewer (but different) axioms. The most appealing of these, from the viewpoint of having the fewest axioms, is due to G.D. Birkhoff (1932) which has only four axioms. These four are: the Unique line assumption (which was called the Point-Line Postulate by Birkhoff), the Number line assumption, the Protractor postulate (to permit the measurement of angles) and an axiom that is equivalent to Playfair's axiom (or the parallel postulate).

The independence of the parallel postulate from Euclid's other axioms was finally demonstrated by Eugenio Beltrami in 1868.
The lunes of Alhazen. The two blue lunes together have the same area as the green right triangle. Alhazen explored what is now known as the Euclidean parallel postulate, the fifth postulate in Euclid's Elements, using a proof by contradiction,. and in effect introducing the concept of motion into geometry.
It considers many hypotheses, including Ishvara. Verses 19–21, postulates Ishvara exists and is the cause, states a consequence of postulate, then presents contrary evidence, and from contradiction concludes that the postulate must be invalid. Centuries later, the 5th century CE Nyaya school scholar Prastapada revisited the premise of Ishvara.
The mentalist postulate is the thesis that meaning in natural language is an information structure that is mentally encoded by human beings. It is a basic premise of some branches of cognitive semantics. Semantic theories implicitly or explicitly incorporating the mentalist postulate include force dynamics and conceptual semantics. Two implications of the mentalist postulate are: first, that research on the nature of mental representations can serve to constrain or enrich semantic theories; and secondly, that results of semantic theories bear directly on the nature of human conceptualization.
Nasir al-Din attempted to derive a proof by contradiction of the parallel postulate. He also considered the cases of what are now known as elliptical and hyperbolic geometry, though he ruled out both of them. Euclidean, elliptical and hyperbolic geometry. The Parallel Postulate is satisfied only for models of Euclidean geometry.
Probably the best known equivalent of Euclid's parallel postulate, contingent on his other postulates, is Playfair's axiom, named after the Scottish mathematician John Playfair, which states: > In a plane, given a line and a point not on it, at most one line parallel to > the given line can be drawn through the point.Euclid's Parallel Postulate > and Playfair's Axiom This axiom by itself is not logically equivalent to the Euclidean parallel postulate since there are geometries in which one is true and the other is not. However, in the presence of the remaining axioms which give Euclidean geometry, each of these can be used to prove the other, so they are equivalent in the context of absolute geometry. Many other statements equivalent to the parallel postulate have been suggested, some of them appearing at first to be unrelated to parallelism, and some seeming so self-evident that they were unconsciously assumed by people who claimed to have proven the parallel postulate from Euclid's other postulates.
However, he did give a postulate which is equivalent to the fifth postulate. Ibn al- Haytham (Alhazen) (965-1039), an Arab mathematician, made an attempt at proving the parallel postulate using a proof by contradiction, in the course of which he introduced the concept of motion and transformation into geometry.: He formulated the Lambert quadrilateral, which Boris Abramovich Rozenfeld names the "Ibn al-Haytham–Lambert quadrilateral", and his attempted proof contains elements similar to those found in Lambert quadrilaterals and Playfair's axiom. The Persian mathematician, astronomer, philosopher, and poet Omar Khayyám (1050–1123), attempted to prove the fifth postulate from another explicitly given postulate (based on the fourth of the five principles due to the Philosopher (Aristotle), namely, "Two convergent straight lines intersect and it is impossible for two convergent straight lines to diverge in the direction in which they converge."Boris A Rosenfeld and Adolf P Youschkevitch (1996), Geometry, p.467 in Roshdi Rashed, Régis Morelon (1996), Encyclopedia of the history of Arabic science, Routledge, .
Bolyai ends his work by mentioning that it is not possible to decide through mathematical reasoning alone if the geometry of the physical universe is Euclidean or non-Euclidean; this is a task for the physical sciences. The independence of the parallel postulate from Euclid's other axioms was finally demonstrated by Eugenio Beltrami in 1868.Beltrami, Eugenio Teoria fondamentale degli spazî di curvatura costante, Annali. di Mat., ser II 2 (1868), 232-255 The various attempted proofs of the parallel postulate produced a long list of theorems that are equivalent to the parallel postulate.
The Saccheri quadrilateral is now sometimes referred to as the Khayyam-Saccheri quadrilateral. The intent of Saccheri's work was ostensibly to establish the validity of Euclid by means of a reductio ad absurdum proof of any alternative to Euclid's parallel postulate. To do so, he assumed that the parallel postulate was false and attempted to derive a contradiction. Since Euclid's postulate is equivalent to the statement that the sum of the internal angles of a triangle is 180°, he considered both the hypothesis that the angles add up to more or less than 180°.
Lorentz also admitted that the postulate of an absolute but undetectable rest frame was purely metaphysical, and had no empirical consequences.
Euclid sometimes distinguished explicitly between "finite lines" (e.g., Postulate 2) and "infinite lines" (book I, proposition 12). However, he typically did not make such distinctions unless they were necessary. The postulates do not explicitly refer to infinite lines, although for example some commentators interpret postulate 3, existence of a circle with any radius, as implying that space is infinite.
1), he believed it was interesting to consider the consequences if we were to assume the postulate of relativity was valid without restriction. This would imply that all forces of nature (not just electromagnetism) must be invariant under the Lorentz transformation. In 1921 Lorentz credited Poincaré for establishing the principle and postulate of relativity and wrote:Lorentz (1921), pp.
1500 in the Novgorod region, though Russian nationalists postulate its great antiquity. The earliest extant manuscript is dated to the 17th century.
They postulate the inherent serialization of such a system of equations may correctly capture causation in all empirical fields, including physics and economics.
Those working with this postulate believe that quintessence became repulsive about ten billion years ago, about 3.5 billion years after the Big Bang.
Khayyam, for example, tried to derive it from an equivalent postulate he formulated from "the principles of the Philosopher" (Aristotle): "Two convergent straight lines intersect and it is impossible for two convergent straight lines to diverge in the direction in which they converge."Boris A. Rosenfeld & Adolf P. Youschkevitch (1996), "Geometry", p. 467, in Roshdi Rashed & Régis Morelon (1996), Encyclopedia of the History of Arabic Science, Vol. 2, pp. 447–494, Routledge, Khayyam then considered the three cases right, obtuse, and acute that the summit angles of a Saccheri quadrilateral can take and after proving a number of theorems about them, he correctly refuted the obtuse and acute cases based on his postulate and hence derived the classic postulate of Euclid, which he didn't realize was equivalent to his own postulate. Another example is al-Tusi's son, Sadr al-Din (sometimes known as "Pseudo-Tusi"), who wrote a book on the subject in 1298, based on al-Tusi's later thoughts, which presented another hypothesis equivalent to the parallel postulate.
Invariably the mistake was assuming some 'obvious' property which turned out to be equivalent to the fifth postulate (Playfair's axiom). Although known from the time of Proclus, this became known as Playfair's Axiom after John Playfair wrote a famous commentary on Euclid in 1795 in which he proposed replacing Euclid's fifth postulate by his own axiom. Proclus (410–485) wrote a commentary on The Elements where he comments on attempted proofs to deduce the fifth postulate from the other four; in particular, he notes that Ptolemy had produced a false 'proof'. Proclus then goes on to give a false proof of his own.
The converse of the parallel postulate: If the sum of the two interior angles equals 180°, then the lines are parallel and will never intersect. Euclid did not postulate the converse of his fifth postulate, which is one way to distinguish Euclidean geometry from elliptic geometry. The Elements contains the proof of an equivalent statement (Book I, Proposition 27): If a straight line falling on two straight lines make the alternate angles equal to one another, the straight lines will be parallel to one another. As De MorganHeath, T.L., The thirteen books of Euclid's Elements, Vol.
In so doing, they helped found what is now known as metamathematics and model theory. Scanlan, M. (1991) "Who were the American Postulate Theorists?", Journal of Symbolic Logic 56, 981–1002. Huntington was perhaps the most prolific of the American postulate theorists, devising sets of axioms (which he called "postulates") for groups, abelian groups, geometry, the real number field, and complex numbers.
Thomas Digges (; c. 1546 – 24 August 1595) was an English mathematician and astronomer. He was the first to expound the Copernican system in English but discarded the notion of a fixed shell of immoveable stars to postulate infinitely many stars at varying distances.. He was also first to postulate the "dark night sky paradox".Al-Khalili, Jim, Everything and Nothing – 1.
Social ecology also incorporates concepts such as interdependence and homeostasis from systems theory to characterize reciprocal and dynamic person-environment transactions., Individuals are key agents in ecological systems. From an ecological perspective, the individual is both a postulate (a basic entity whose existence is taken for granted) and a unit of measurement. As a postulate, an individual has several characteristics.
Horizontal resistance is the resistance that invariably remains after a matching allo-infection has occurred. To postulate that horizontal resistance does not occur would be to postulate an absolute susceptibility. Such a level of susceptibility is experimentally unproved, and is theoretically impossible. Horizontal resistance is polygenically inherited and it can be exhibited at any level between its minimum and its maximum.
Attempts to logically prove the parallel postulate, rather than the eighth axiom,Schopenhauer is referring to Euclid's Common Notion 4: Figures coinciding with one another are equal to one another. were criticized by Arthur Schopenhauer. However, the argument used by Schopenhauer was that the postulate is evident by perception, not that it was not a logical consequence of the other axioms.
There are lyrical undertones suggestive of the intimate relationship they had. But since there are no explicit representation, one can only postulate a possibility.
The Planck postulate (or Planck's postulate), one of the fundamental principles of quantum mechanics, is the postulate that the energy of oscillators in a black body is quantized, and is given by :E=nh u\,, where n is an integer (1, 2, 3, ...), h is Planck's constant, and u (the Greek letter nu, not the Latin letter v) is the frequency of the oscillator. The postulate was introduced by Max Planck in his derivation of his law of black body radiation in 1900. This assumption allowed Planck to derive a formula for the entire spectrum of the radiation emitted by a black body. Planck was unable to justify this assumption based on classical physics; he considered quantization as being purely a mathematical trick, rather than (as is now known) a fundamental change in the understanding of the world.
Euclid believed that his axioms were self-evident statements about physical reality. Euclid's proofs depend upon assumptions perhaps not obvious in Euclid's fundamental axioms, in particular that certain movements of figures do not change their geometrical properties such as the lengths of sides and interior angles, the so-called Euclidean motions, which include translations, reflections and rotations of figures. See, for example: and The group of motions underlie the metric notions of geometry. See Taken as a physical description of space, postulate 2 (extending a line) asserts that space does not have holes or boundaries (in other words, space is homogeneous and unbounded); postulate 4 (equality of right angles) says that space is isotropic and figures may be moved to any location while maintaining congruence; and postulate 5 (the parallel postulate) that space is flat (has no intrinsic curvature).
If you restrict your attention to just the standalone theory of relativity then yes you need the postulate. But given all the available knowledge we don't need to postulate it. In other words, different domains of knowledge are overlapping and thus taken together have more information than necessary. This can be summarized as follows: #Experimental results rule out the validity of the Galiliean transformations.
In absolute geometry, the Saccheri–Legendre theorem states that the sum of the angles in a triangle is at most 180°.. Absolute geometry is the geometry obtained from assuming all the axioms that lead to Euclidean geometry with the exception of the axiom that is equivalent to the parallel postulate of Euclid.There are many axiom systems that yield Euclidean geometry and they all contain an axiom that is logically equivalent to Euclid's parallel postulate. The theorem is named after Giovanni Girolamo Saccheri and Adrien-Marie Legendre. The existence of at least one triangle with angle sum of 180 degrees in absolute geometry implies Euclid's parallel postulate.
Verses 19–21 postulate that Ishvara exists and is the cause, states a consequence of the postulate, then presents contrary evidence, and from contradiction concludes that the postulate must be invalid. Other scholars of Nyaya school reconsidered this question and offered arguments for what is God (Ishvara) and various arguments to prove the existence of Ishvara.Francis X. Clooney (2010), Hindu God, Christian God: How Reason Helps Break Down the Boundaries, Oxford University Press, , pages 18–19, 35–39 The 5th century CE Nyaya school scholar Prastapada, for example, revisited the premise of God. He was followed by Udayana, who in his text Nyayakusumanjali, interpreted "it" in verse 4.1.
To the ancients, the parallel postulate seemed less obvious than the others. They aspired to create a system of absolutely certain propositions, and to them it seemed as if the parallel line postulate required proof from simpler statements. It is now known that such a proof is impossible, since one can construct consistent systems of geometry (obeying the other axioms) in which the parallel postulate is true, and others in which it is false. Euclid himself seems to have considered it as being qualitatively different from the others, as evidenced by the organization of the Elements: his first 28 propositions are those that can be proved without it.
One of the most notable influences of Euclid on modern mathematics is the discussion of the parallel postulate. In Book I, Euclid lists five postulates, the fifth of which stipulates > If a line segment intersects two straight lines forming two interior angles > on the same side that sum to less than two right angles, then the two lines, > if extended indefinitely, meet on that side on which the angles sum to less > than two right angles. The different versions of the parallel postulate result in different geometries. This postulate plagued mathematicians for centuries due to its apparent complexity compared to the other four postulates.
In 1910 he was to first who tried to derive the Lorentz transformation by group theory only using the relativity principle, and without the postulate of the constancy of the speed of light (1910b, 1911b, 1911c, 1911h). Although he derived the correct transformation, the invariant limiting speed remained undefined. Ignatowski had to resort to length contraction of moving electrostatic fields in order to identify this limiting velocity with the velocity of light in vacuum. While some said that this approach was insufficient and the second postulate is still needed, others continued the attempts to derive special relativity without the light postulate (see Postulates of special relativity).
New York: Dover. p 200 Boethius translated 'postulate' as petitio and called the axioms notiones communes but in later manuscripts this usage was not always strictly kept.
181 Two angles are called complementary if their sum is a right angle.Wentworth p. 9 Book 1 Postulate 4 states that all right angles are equal, which allows Euclid to use a right angle as a unit to measure other angles with. Euclid's commentator Proclus gave a proof of this postulate using the previous postulates, but it may be argued that this proof makes use of some hidden assumptions.
The angle addition postulate states that if B is in the interior of angle AOC, then : m\angle AOC = m\angle AOB + m\angle BOC The measure of the angle AOC is the sum of the measure of angle AOB and the measure of angle BOC. In this postulate it does not matter in which unit the angle is measured as long as each angle is measured in the same unit.
Hyperbolic geometry is more closely related to Euclidean geometry than it seems: the only axiomatic difference is the parallel postulate. When the parallel postulate is removed from Euclidean geometry the resulting geometry is absolute geometry. There are two kinds of absolute geometry, Euclidean and hyperbolic. All theorems of absolute geometry, including the first 28 propositions of book one of Euclid's Elements, are valid in Euclidean and hyperbolic geometry.
470, in Roshdi Rashed & Régis Morelon (1996), Encyclopedia of the History of Arabic Science, Vol. 2, pp. 447–494, Routledge, London and New York: All of these early attempts made at trying to formulate non-Euclidean geometry, however, provided flawed proofs of the parallel postulate, containing assumptions that were essentially equivalent to the parallel postulate. These early attempts did, however, provide some early properties of the hyperbolic and elliptic geometries.
The angle addition postulate states that if B is in the interior of angle AOC, then m\angle AOC = m\angle AOB + m\angle BOC The measure of the angle AOC is the sum of the measure of angle AOB and the measure of angle BOC. In this postulate, it does not matter in which unit the angle is measured—as long as each angle is measured in the same unit.
The segment addition postulate can be used to add congruent segment or segments with equal lengths, and consequently substitute other segments into another statement to make segments congruent.

Effectively, the postulate states that the structure of a transition state resembles that of the species nearest to it in free energy. This can be explained with reference to potential energy diagrams: Energy diagrams showing how to interpret Hammond's Postulate In case (a), which is an exothermic reaction, the energy of the transition state is closer in energy to that of the reactant than that of the intermediate or the product. Therefore, from the postulate, the structure of the transition state also more closely resembles that of the reactant. In case (b), the energy of the transition state is close to neither the reactant nor the product, making none of them a good structural model for the transition state.
The Hammond–Leffler postulate states that the structure of the transition state more closely resembles either the products or the starting material, depending on which is higher in enthalpy. A transition state that resembles the reactants more than the products is said to be early, while a transition state that resembles the products more than the reactants is said to be late. Thus, the Hammond–Leffler Postulate predicts a late transition state for an endothermic reaction and an early transition state for an exothermic reaction. A dimensionless reaction coordinate that quantifies the lateness of a transition state can be used to test the validity of the Hammond–Leffler postulate for a particular reaction.
This postulate is a physical postulate of existence. It does not, however, as worded just previously, say that there is only one kind of heat. This paper of Carathéodory states as proviso 4 of its account of such walls: "Whenever each of the systems S1 and S2 is made to reach equilibrium with a third system S3 under identical conditions, systems S1 and S2 are in mutual equilibrium".Carathéodory, C. (1909), Section 6.
A statement that is equivalent to the parallel postulate is that there exists a triangle whose angles add up to 180°. Since spherical geometry violates the parallel postulate, there exists no such triangle on the surface of a sphere. The sum of the angles of a triangle on a sphere is , where f is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of f, this exceeds 180°.
He also continuously provides healing, resurrection and other miscellaneous help for the Avatar. One of the most famous characteristics of Lord British is that he is (supposedly) indestructible. In the past, he has been killed as a result of various glitches and exploits. This fact has led to the naming of the "Lord British Postulate", a postulate that in any game if a creature is alive, someone somewhere will try to kill it.
If the original axioms Q are not consistent, then no new axiom is independent. If they are consistent, then P can be shown independent of them if adding P to them, or adding the negation of P, both yield consistent sets of axioms. Kenneth Kunen, Set Theory: An Introduction to Independence Proofs, page xi. For example, Euclid's axioms including the parallel postulate yield Euclidean geometry, and with the parallel postulate negated, yields non-Euclidean geometry.

The very old problem of proving Euclid's Fifth Postulate, the "Parallel Postulate", from his first four postulates had never been forgotten. Beginning not long after Euclid, many attempted demonstrations were given, but all were later found to be faulty, through allowing into the reasoning some principle which itself had not been proved from the first four postulates. Though Omar Khayyám was also unsuccessful in proving the parallel postulate, his criticisms of Euclid's theories of parallels and his proof of properties of figures in non-Euclidean geometries contributed to the eventual development of non-Euclidean geometry. By 1700 a great deal had been discovered about what can be proved from the first four, and what the pitfalls were in attempting to prove the fifth.
A part of Khayyam's commentary on Euclid's Elements deals with the parallel axiom. The treatise of Khayyam can be considered the first treatment of the axiom not based on petitio principii, but on a more intuitive postulate. Khayyam refutes the previous attempts by other mathematicians to prove the proposition, mainly on grounds that each of them had postulated something that was by no means easier to admit than the Fifth Postulate itself. Drawing upon Aristotle's views, he rejects the usage of movement in geometry and therefore dismisses the different attempt by Al- Haytham.. Excerpt: In some sense, his treatment was better than ibn al- Haytham's because he explicitly formulated a new postulate to replace Euclid's rather than have the latter hidden in a new definition.
Unsatisfied with the failure of mathematicians to prove Euclid's statement from his other postulates, Omar tried to connect the axiom with the Fourth Postulate, which states that all right angles are equal to one another. Khayyam was the first to consider the three cases of acute, obtuse, and right angle for the summit angles of a Khayyam-Saccheri quadrilateral, three cases which are exhaustive and pairwise mutually exclusive. After proving a number of theorems about them, he proved that the Postulate V is a consequence of the right angle hypothesis, and refuted the obtuse and acute cases as self-contradictory. Khayyam's elaborate attempt to prove the parallel postulate was significant for the further development of geometry, as it clearly shows the possibility of non-Euclidean geometries.
This type of comparison is especially useful because most transition states cannot be characterized experimentally. Hammond's postulate also helps to explain and rationalize the Bell–Evans–Polanyi principle. Namely, this principle describes the experimental observation that the rate of a reaction, and therefore its activation energy, is affected by the enthalpy of that reaction. Hammond's postulate explains this observation by describing how varying the enthalpy of a reaction would also change the structure of the transition state.
Similarly, the existence of at least one triangle with angle sum of less than 180 degrees implies the characteristic postulate of hyperbolic geometry. Max Dehn gave an example of a non-Legendrian geometry where the angle sum of a triangle is greater than 180 degrees, and a semi-Euclidean geometry where there is a triangle with an angle sum of 180 degrees but Euclid's parallel postulate fails. In Dehn's geometries the Archimedean axiom does not hold.
Saccheri, Lambert, and Legendre each did excellent work on the problem in the 18th century, but still fell short of success. In the early 19th century, Gauss, Johann Bolyai, and Lobatchewsky, each independently, took a different approach. Beginning to suspect that it was impossible to prove the Parallel Postulate, they set out to develop a self-consistent geometry in which that postulate was false. In this they were successful, thus creating the first non-Euclidean geometry.

Saccheri gave a proof as well but using a more explicit assumption. In Hilbert's axiomatization of geometry this statement is given as a theorem, but only after much groundwork. One may argue that, even if postulate 4 can be proven from the preceding ones, in the order that Euclid presents his material it is necessary to include it since without it postulate 5, which uses the right angle as a unit of measure, makes no sense.Heath pp.
According to the first postulate of the special theory of relativity: This postulate defines an inertial frame of reference. The special principle of relativity states that physical laws should be the same in every inertial frame of reference, but that they may vary across non-inertial ones. This principle is used in both Newtonian mechanics and the theory of special relativity. Its influence in the latter is so strong that Max Planck named the theory after the principle.
Wolff, P. Breakthroughs in Mathematics, 1963, New York: New American Library, pp 47–48 Ancient geometers maintained some distinction between axioms and postulates. While commenting on Euclid's books, Proclus remarks that, "Geminus held that this [4th] Postulate should not be classed as a postulate but as an axiom, since it does not, like the first three Postulates, assert the possibility of some construction but expresses an essential property."Heath, T. 1956. The Thirteen Books of Euclid's Elements.
These are the adoptable theoretical postulates (and they must still be ordered by some kind of simplicity). In other cases, the theoretical postulate is in conflict with the evidence and measurement-based observations, so the postulate must be rejected. In this way, Kyburg provides a probability-mediated model of predictive power, scientific theory-formation, the Web of Belief, and linguistic variation. The theory of acceptance mediates the tension between linguistic categorical assertion and probability-based epistemology.
The author Richard Webster identifies Organization of Behavior as the most influential outline of Hebb's postulate. According to Webster, the hypothesis has classic status within science and is supported by recent research.

The phrase "single postulate" is just used in comparison with the original "two postulate" formulation. The real question here is whether universal lightspeed can be deduced rather than assumed. The Lorentz transformations, up to a nonnegative free parameter, can be derived without first postulating the universal lightspeed. Experiment rules out the validity of the Galilean transformations and this means the parameter in the Lorentz transformations is nonzero hence there is a finite maximum speed before anything has been said about light.
Bertrand's postulate was proposed for applications to permutation groups. Sylvester (1814–1897) generalized the weaker statement with the statement: the product of k consecutive integers greater than k is divisible by a prime greater than k. Bertrand's (weaker) postulate follows from this by taking k = n, and considering the k numbers n + 1, n + 2, up to and including n + k = 2n, where n > 1\. According to Sylvester's generalization, one of these numbers has a prime factor greater than k.
Khayyam then considered the three cases right, obtuse, and acute that the summit angles of a Saccheri quadrilateral can take and after proving a number of theorems about them, he (correctly) refuted the obtuse and acute cases based on his postulate and hence derived the classic postulate of Euclid. It was not until 600 years later that Giordano Vitale made an advance on Khayyam in his book Euclide restituo (1680, 1686), when he used the quadrilateral to prove that if three points are equidistant on the base AB and the summit CD, then AB and CD are everywhere equidistant. Saccheri himself based the whole of his long and ultimately flawed proof of the parallel postulate around the quadrilateral and its three cases, proving many theorems about its properties along the way.
The prime number theorem (PNT) implies that the number of primes up to x is roughly x/ln(x), so if we replace x with 2x then we see the number of primes up to 2x is asymptotically twice the number of primes up to x (the terms ln(2x) and ln(x) are asymptotically equivalent). Therefore the number of primes between n and 2n is roughly n/ln(n) when n is large, and so in particular there are many more primes in this interval than are guaranteed by Bertrand's Postulate. So Bertrand's postulate is comparatively weaker than the PNT. But PNT is a deep theorem, while Bertrand's Postulate can be stated more memorably and proved more easily, and also makes precise claims about what happens for small values of n.
Premise of Playfair's axiom: a line and a point not on the line Logical consequence of Playfair's axiom: a second line, parallel to the first, passing through the point In geometry, Playfair's axiom is an axiom that can be used instead of the fifth postulate of Euclid (the parallel postulate): > In a plane, given a line and a point not on it, at most one line parallel to > the given line can be drawn through the point. It is equivalent to Euclid's parallel postulate in the context of Euclidean geometrymore precisely, in the context of absolute geometry. and was named after the Scottish mathematician John Playfair. The "at most" clause is all that is needed since it can be proved from the remaining axioms that at least one parallel line exists.
In geometry, the point–line–plane postulate is a collection of assumptions (axioms) that can be used in a set of postulates for Euclidean geometry in two (plane geometry), three (solid geometry) or more dimensions.

A theory, for an E2 reaction, by Joseph Bunnett suggests the lowest pass through the energy barrier between reactants and products is gained by an adjustment between the degrees of Cβ-H and Cα-X rupture at the transition state. The adjustment involves much breaking of the bond more easily broken, and a small amount of breaking of the bond which requires more energy. This conclusion by Bunnett is a contradiction from the Hammond postulate. The Hammond postulate is the opposite of what Bunnett theorized.
In turn, this change in geometric structure would alter the energy of the transition state, and therefore the activation energy and reaction rate as well. The postulate has also been used to predict the shape of reaction coordinate diagrams. For example, electrophilic aromatic substitutions involves a distinct intermediate and two less well defined states. By measuring the effects of aromatic substituents and applying Hammond's postulate it was concluded that the rate-determining step involves formation of a transition state that should resemble the intermediate complex.

In other words, Planck then contemplated virtual oscillators. In 1905, Albert Einstein adapted the Planck postulate to explain the photoelectric effect, but Einstein proposed that the energy of photons themselves was quantized (with photon energy given by the Planck-Einstein relation), and that quantization was not merely a feature of microscopic oscillators. Planck's postulate was further applied to understanding the Compton effect, and was applied by Niels Bohr to explain the emission spectrum of the hydrogen atom and derive the correct value of the Rydberg constant.
Isotropy is guaranteed by the fourth postulate, that all right angles are equal. For an example of homogeneity, note that Euclid's proposition I.1 implies that the same equilateral triangle can be constructed at any location, not just in locations that are special in some way. The lack of boundaries follows from the second postulate, extensibility of a line segment. One way in which elliptic geometry differs from Euclidean geometry is that the sum of the interior angles of a triangle is greater than 180 degrees.
Hammond postulate is another tool which assists in drawing the energy of a transition state relative to a reactant, an intermediate or a product. It states that the transition state resembles the reactant, intermediate or product that it is closest in energy to, as long the energy difference between the transition state and the adjacent structure is not too large. This postulate helps to accurately predict the shape of a reaction coordinate diagram and also gives an insight into the molecular structure at the transition state.
Chapter 20 is an examination of the supply function. Keynes makes use for the first time of the "first postulate of classical economics", and also for the first time assumes the existence of a unit of value allowing outputs to be compared in real terms. He depends heavily on an assumption of perfect competition, which indeed is implicit in the "first postulate". An important difference is that when competition is not perfect, "it is marginal revenue, not price, which determines the output of the individual producer".
Lobachevsky's main achievement is the development (independently from János Bolyai) of a non- Euclidean geometry, also referred to as Lobachevskian geometry. Before him, mathematicians were trying to deduce Euclid's fifth postulate from other axioms. Euclid's fifth is a rule in Euclidean geometry which states (in John Playfair's reformulation) that for any given line and point not on the line, there is only one line through the point not intersecting the given line. Lobachevsky would instead develop a geometry in which the fifth postulate was not true.

It thus seemed that light traveled different distances at the same time, which led George FitzGerald and Hendrik Lorentz (Lorentz ether theory) to postulate that distances shortened and time dilated in direction of motion (FitzGerald-Lorentz contraction).

In "Appendix exhibiting the absolute science of space: independent of the truth or falsity of Euclid's Axiom XI (by no means previously decided)" It is sometimes referred to as neutral geometry,Greenberg cites W. Prenowitz and M. Jordan (Greenberg, p. xvi) for having used the term neutral geometry to refer to that part of Euclidean geometry that does not depend on Euclid's parallel postulate. He says that the word absolute in absolute geometry misleadingly implies that all other geometries depend on it. as it is neutral with respect to the parallel postulate.
Thorngate's postulate of commensurate complexity, also referred to as Thorngate's impostulate of theoretical simplicity is the description of a phenomenon in social science theorizing. Karl E. Weick maintains that research in the field of social psychology can – at any one time – achieve only two of the three meta-theoretical virtues of "Generality", "Accuracy" and "Simplicity." One of these aspects therefore must always be subordinated to the others. The postulate is named for the Canadian social psychologist Warren Thorngate of the University of Alberta, whose work is quoted by Weick.
In Nyāya Sūtra's Book 4, Chapter 1, verses 19-21, postulates God exists, states a consequence, then presents contrary evidence, and from contradiction concludes that the postulate must be invalid. A literal interpretation of the three verses suggests that Nyaya school rejected the need for a God for the efficacy of human activity. Since human action and results do not require assumption or need of the existence of God, sutra IV.1.21 is seen as a criticism of the "existence of God and theism postulate". The context of the above verses includes various efficient causes.
Other researchers have concluded from other data that if gravitational absorption does exist, it must be at least five orders of magnitude smaller than Majorana's experiments suggest. Critical of Albert Einstein's relativity theory, Majorana tried to disprove Einstein’s postulate on the constancy of the speed of light, but he failed, and therefore his experiments confirmed Einstein's postulate. Majorana also confirmed Isaac Newton’s law of universal gravitation to high precision. His later work at Bologna was influenced by correspondence with his nephew Ettore Majorana (1906–1938), a great physicist in his own right.
That section includes the phrase "Ignatowski was forced to recourse to electrodynamics to include the speed of light.". So, the trio of "principle of relativity+Maxwell+numerical values from experiment" gives special relativity and this should be compared with "principle of relativity+second postulate+Maxwell+numerical values from experiment". Since Einstein's 1905 paper is all about electrodynamics he is assuming Maxwell's equations, and the theory isn't practically applicable without numerical values. When compared like with like, from the point of view of asking what is knowable, the second postulate can be deduced.
Probably the oldest, and most famous, list of axioms are the 4 + 1 Euclid's postulates of plane geometry. The axioms are referred to as "4 + 1" because for nearly two millennia the fifth (parallel) postulate ("through a point outside a line there is exactly one parallel") was suspected of being derivable from the first four. Ultimately, the fifth postulate was found to be independent of the first four. Indeed, one can assume that exactly one parallel through a point outside a line exists, or that infinitely many exist.
The state postulate says: A more general statement of the state postulate says: the state of a simple system is completely specified by r+1 independent, intensive properties where r is the number of significant work interactions . A system is considered to be a simple compressible one in the absence of certain effects which are uncommon in many engineering applications. These are electromagnetic and gravitational fields, surface tension, and motion. For such a system, only two independent intensive variables are sufficient to derive all the others by use of an equation of state.
Or it may be incomplete simply because not all the necessary axioms have been discovered or included. For example, Euclidean geometry without the parallel postulate is incomplete, because some statements in the language (such as the parallel postulate itself) can not be proved from the remaining axioms. Similarly, the theory of dense linear orders is not complete, but becomes complete with an extra axiom stating that there are no endpoints in the order. The continuum hypothesis is a statement in the language of ZFC that is not provable within ZFC, so ZFC is not complete.
Donald Hebb theorized that strengthening of synaptic connections occurred because of coordinated activity between the pre-synaptic terminal and post- synaptic dendrite. According to Hebb, these two cells are strengthened because their signaling occurs together in space and/or time, also known as coincident activity. This postulate is often summarized as Cells that fire together, wire together, which means that the synapses that have neurons with coincident firing are strengthened, while the other synapses on these neurons remain unchanged. Hebb's postulate has provided a conceptual framework for how synaptic plasticity underlies long-term information storage.
The relation accounts for the quantized nature of light and plays a key role in understanding phenomena such as the photoelectric effect and black-body radiation (where the related Planck postulate can be used to derive Planck's law).
Thus, "assumption" connotes other associations than the contemporary standard sense of "that which is assumed or taken for granted; a supposition, postulate" (only the 11th of 12 senses of "assumption", and the 10th of 11 senses of "assume").

4 although it also appeared in print as early as April 1870. The word "conspiracy" derives from the Latin con- ("with, together") and spirare ("to breathe"). Robert Blaskiewicz comments that examples of the term were used as early as the nineteenth century and states that its usage has always been derogatory. According to a study by Andrew McKenzie-McHarg, in contrast, in the nineteenth century the term conspiracy theory simply "suggests a plausible postulate of a conspiracy" and "did not, at this stage, carry any connotations, either negative or positive", though sometimes a postulate so- labeled was criticized.
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean parallel postulate and neither condition can be proven without appealing to the Euclidean parallel postulate or one of its equivalent formulations. By comparison, a quadrilateral with just one pair of parallel sides is a trapezoid in American English or a trapezium in British English.
Since the publication of Euclid's Elements circa 300 BCE, many geometers made attempts to prove the parallel postulate. Some tried to prove it by assuming its negation and trying to derive a contradiction. Foremost among these were Proclus, Ibn al-Haytham (Alhacen), Omar Khayyám,See for instance, Nasīr al- Dīn al-Tūsī, Witelo, Gersonides, Alfonso, and later Giovanni Gerolamo Saccheri, John Wallis, Johann Heinrich Lambert, and Legendre. Their attempts were doomed to failure (as we now know, the parallel postulate is not provable from the other postulates), but their efforts led to the discovery of hyperbolic geometry.
The Born rule (also called the Born law, Born's postulate, Born's rule, or Born's law) is a key postulate of quantum mechanics which gives the probability that a measurement of a quantum system will yield a given result.The time evolution of a quantum system is entirely deterministic according to the Schrödinger equation. It is through the Born Rule that probability enters into the theory. In its simplest form, it states that the probability density of finding a particle at a given point is proportional to the square of the magnitude of the particle's wavefunction at that point.
Coordinating the work of the RR&R; at a national level and acting as the society's Board of Trustees is the Ephorate, a council comprising three Ephors, a constitutional office found in ancient Sparta. Members are organized into four ranks: Postulates, Rascals, Rogues, and Rapscallions. A man joins the society at the rank of Postulate. Upon completing in one “Mass Challenge” and one “Research Report” within two years, the Postulate is elevated to Rascal and receives from the Lair his "Rascal Challenge," a specific research topic on which he is challenged to discover interesting and important results.
The general approach of the mechanical philosophers was to postulate theories of the kind now called "contact action". Huygens adopted this method, but not without seeing its difficulties and failures. Leibniz, his student in Paris, abandoned the theory.Garber and Ayers, p. 595.
Some features of the conventionality of synchronization were discussed by Henri Poincaré.Galison (2002).Darrigol (2005). In 1898 (in a philosophical paper) he argued that the postulate of light speed constancy in all directions is useful to formulate physical laws in a simple way.
The highest good also requires the highest level of happiness, in order to reward the highest level of virtue. We therefore need to postulate that there is an omniscient God who can order the world justly and reward us for our virtue.
Theories of acquisition involving variations of input postulate that heritage language learners' production of the heritage language diverges from that of their monolingual peers who speak the same language because the two groups are exposed to different dialects and quantities of input.
Bertrand himself verified his statement for all numbers in the interval His conjecture was completely proved by Chebyshev (1821–1894) in 1852. (Proof of the postulate: 371-382). Also see Mémoires de l'Académie Impériale des Sciences de St. Pétersbourg, vol. 7, pp.
New York: McGraw-Hill. . Protectionists postulate that new industries may require protection from entrenched foreign competition in order to develop. This was Alexander Hamilton's argument in his "Report on Manufactures", and the primary reason why George Washington signed the Tariff Act of 1789.
18, 19. In affine geometry, there is no metric structure but the parallel postulate does hold. Affine geometry provides the basis for Euclidean structure when perpendicular lines are defined, or the basis for Minkowski geometry through the notion of hyperbolic orthogonality.Coxeter 1942, p.
Max Ernst August Bodenstein (July 15, 1871 – September 3, 1942) was a German physical chemist known for his work in chemical kinetics. He was first to postulate a chain reaction mechanism and that explosions are branched chain reactions, later applied to the atomic bomb.
The Syrian–Egyptian traditions postulate a remote, supreme Godhead, the Monad. From this highest divinity emanate lower divine beings, known as Aeons. The Demiurge, one of those Aeons, creates the physical world. Divine elements "fall" into the material realm, and are locked within human beings.
Redding discusses the formula: efficiency = effectiveness/cost. Ultimately, more communication does not equal more effectiveness. # Redundancy: This postulates deals with the repetition of messages and how effective and comprehensive the messages are. # Communication Overload: This postulate deals with an individuals limit of processing messages.
Tisza, L. (1966), p. 108.Bailyn, M. (1994), p. 20. This postulate is sometimes, but not often, called the minus first law of thermodynamics. A notable exception exists for isolated quantum systems which are many-body localized and which never reach internal thermal equilibrium.
Geometers of the 18th century struggled to define the boundaries of the Euclidean system. Many tried in vain to prove the fifth postulate from the first four. By 1763, at least 28 different proofs had been published, but all were found incorrect.Hofstadter 1979, p. 91.
Now it can be seen that no other parallels exist. If n was a second line through P, then n makes an acute angle with t (since it is not the perpendicular) and the hypothesis of the fifth postulate holds, and so, n meets \ell.
He was also the first to find the general geometric solution to cubic equations. He was also very influential in calendar reform. In the 13th century, Nasir al-Din Tusi (Nasireddin) made advances in spherical trigonometry. He also wrote influential work on Euclid's parallel postulate.
The implementation of the Postulate Sejm was delayed, and eventually it held only four sessions, all in Lviv (Lwów): in 1782, 1784, 1786 and 1788. The body had no real power; it could only write petitions to the monarch, who had no obligation to act on them. Polish legal scholar Stanisław Grodziski noted that while the Sejm, on the surface, continued the Polish parliamentary tradition, the real goal of the powerless body, as intended by the Austrian court, was to drive a wedge between the various groups of Polish nobility, reducing their unity and influence. The Postulate Sejm was composed of wealthy nobility and two deputies from the city of Lviv.
Not only foundationalism of any kind is rejected but reliabilism is not accepted either, since no procedure is to be unconditionally trusted come what may. Peña rehabilitates induction as a sound ground even for logical truths (he follows the outdated opinion of John Stuart Mill). The choice among alternative logical systems has to be made in accordance with plausible criteria, one of which is fitness with the best explanation of available evidence, thus resorting to an optimization postulate, which in turn gets circularly warranted by its epistemological fruitness. That optimization postulate is a rationality ideal which also provides a ground for assuming God's existence.
We can know by self-examination that such virtue does not exist in us now, nor is it likely to exist in the foreseeable future. In fact, the only way in which the fallible human will can become similar to the holy will is for it to take an eternity to achieve perfection. Therefore, we can postulate the existence of immortality. If we do not postulate it, we will be led to either soften the demands of morality in order to make them achievable here and now or we will make the absurd demand on ourselves that we must achieve the holy will now.
In geometry, the Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC. This is related to the triangle inequality, which states that AB + BC \geq AC with equality if and only if A, B, and C are collinear (on the same line). This in turn is equivalent to the proposition that the shortest distance between two points lies on a straight line. The segment addition postulate is often useful in proving results on the congruence of segments.
The parallel postulate (Postulate 5): If two lines intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough. Euclidean geometry is an axiomatic system, in which all theorems ("true statements") are derived from a small number of simple axioms. Until the advent of non-Euclidean geometry, these axioms were considered to be obviously true in the physical world, so that all the theorems would be equally true. However, Euclid's reasoning from assumptions to conclusions remains valid independent of their physical reality.
One reason that the ancients treated the parallel postulate as less certain than the others is that verifying it physically would require us to inspect two lines to check that they never intersected, even at some very distant point, and this inspection could potentially take an infinite amount of time.For the assertion that this was the historical reason for the ancients considering the parallel postulate less obvious than the others, see Nagel and Newman 1958, p. 9. The modern formulation of proof by induction was not developed until the 17th century, but some later commentators consider it implicit in some of Euclid's proofs, e.g., the proof of the infinitude of primes.
During his time at the University of Bonn, Delboeuf published Prolégomènes philosophiques à la géométrie (1860), disputing his mentor Ueberweg’s concept of Euclidean space and earning the praise of Bertrand Russell. He argued that, in order to use geometry to find the fundamental qualities of “determinations of space,” we must first understand the concepts of both “determination” and “space.” In this paper, he independently discovered Euclidean postulate 5. Postulate 5 states that, if a line intersects two straight lines that together form two interior angles on the same side that sum to less than 180 degrees, then the two straight lines must meet on that side.
In November 1970 De Dominicis presented at Franco Toselli Gallery in Milan a series of works as the ball, the stone and the invisible cylinder, but also the radioactive object, two identical jars and a cat with a tag announcing the postulate of the "Second Immortality Solution".
Researchers found that African Grey parrots who prefer to use their right foot showed a marked increase in the number of words within their lexicon as compared to parrots who were left- footed. Scientists postulate that parrots may have lateralization of brain function, much like mammals do.
Some scientists postulate a fourth stage of ecological succession at whale fall sites, called the "reef stage." A whale fall enters this stage once the organic compounds have been exhausted and only minerals remain in the bones, which provide a hard substrate for suspension and filter feeders.
"Scientific knowledge can prove and postulate the Buddhist doctrine, but it cannot ascertain the realities of the Buddhist doctrine."p. 86 Taixu, "Science and Buddhism" Lectures in Buddhism Paris, 1928. He understood Buddhism to be scientific and yet surpassing science. Like other Buddhist modernists, Taixu condemned superstition.
Pepromene's name is speculated to have numerous different origins; some postulate it is derived from the Greek , peprosthai, meaning "to be furnished, fulfilled or fated". However, others suggest that the same πεπερατοσθαι (pepratosthai) means "finite", implying finite nature; the fact that nothing in this life lasts forever.
Other explanations postulate that polygyny is a tool used to ward off inclinations towards infidelity. In Edith Boserup's 1970 article on the study of Sub-Saharan African polygyny, higher incidences of adultery and prostitution were recorded in regions were polygyny was practiced, but delayed by males.
Some antinatalists are also vegetarians or vegans for moral reasons, and postulate that such views should complement each other as having a common denominator: not causing harm to other sentient beings. K. Akerma, Ist der Vegetarismus ein Antinatalismus?, Pro iure animalis, 24 March 2014. English translation.
In gymnastics, human tower is the highest and largest mounting. On the shoulder of the components of the base layer, put the feet of components of the second floor. In the same way, the components of higher floors are accumulated. The mounting is performed in sitting postulate.
It cannot reinvent reasons; it cannot postulate some principles and deduce moral duties from them. Ethical principles can only be systematizations of a given practice of reasoning. Nida-Rümelin takes the side of pragmatism in its conflict against rationalism.Nida-Rümelin, J., Philosophie und Lebensform, Frankfurt am Main: Suhrkamp, 2009.
Though confirming the postulate in general, Fred Dickinson, Carol Blair and Brian L. Ott criticized Weicks use of the word "accurate". Accuracy is hard to achieve, especially if the topic is difficult to qualify, e. g. in researching memory. They suggest replacing the term "accurate" with "interpretive utility".
While they recognize that conclusive evidence has not been found, the evidence that has been found there fits with what is known of the history of that time and they postulate that if Le Griffon is found elsewhere, that would deepen the mystery of the find by Cullis.
Both Dean and Bloomer postulate different rooms served different functions,Bloomer, William W. Moon House: A Pueblo III Period Cliff Dwelling Complex in Southeastern Utah. Unpublished Master's Thesis. Department of Anthropology, Washington State University. pp. 1-213 and each section of the Moon House complex had a different function.
Both powers follow from the postulate that supreme executive organs hold ultimate responsibility; an organ cannot be considered responsible for what it cannot effectively control. There are departures from this general principle, however. Some subordinate organs are "independent" (""); they are subject to management authority but not injunction authority.
Artist's conception of the completely constructed site. Archaeologists have long-debated the functions of the Poverty Point site. One of the main questions has been whether it was used for a settlement or only for periodic events. Archaeologists postulate that houses were constructed on top of the concentric ridges.
Joseph Marie de Tilly (16 August 1837 - 4 August 1906) was a Belgian military man and mathematician. He was born in Ypres, Belgium. In 1858, he became a teacher in mathematics at the regimental school. He began with studying geometry, particularly Euclid's fifth postulate and non-Euclidean geometry.
The existence of change is hard to deny, and if we have to postulate something unobserved in order to explain what is observed, that is a valid indirect demonstration (by abductive reasoning). Moreover, something like a prime substance is posited by physics in the form of matter/energy.
1, Dover, 1956, pg.309. pointed out, this is logically equivalent to (Book I, Proposition 16). These results do not depend upon the fifth postulate, but they do require the second postulateCoxeter, H.S.M., Non-Euclidean Geometry, 6th Ed., MAA 1998, pg.3 which is violated in elliptic geometry.
There are several theories concerning his early life. Some fiction writers postulate that he was in actuality Akechi Mitsuhide. It is not certain whether Mitsuhide died at the Battle of Yamazaki or not, and some suppose that he survived and began a new life as the priest Tenkai.
Ptolemy, the Greek writer from 100 AD refers to Nagadipoi as one of the coastal towns of Taprobana. Naga identity was visible through personal names which observed in Pali chronicles and the Tamil Sangam literature. Some scholars postulate that the Naga people were the ancestors of Tamil-speaking Dravidians.
Further information would be needed in order to predict the structure or characteristics of the transition state. Case (c) depicts the potential diagram for an endothermic reaction, in which, according to the postulate, the transition state should more closely resemble that of the intermediate or the product. Another significance of Hammond’s postulate is that it permits us to discuss the structure of the transition state in terms of the reactants, intermediates, or products. In the case where the transition state closely resembles the reactants, the transition state is called “early” while a “late” transition state is the one that closely resembles the intermediate or the product. An example of the “early” transition state is chlorination.
Effectively, the postulate states that the structure of a transition state resembles that of the species nearest to it in free energy. This can be explained with reference to potential energy diagrams: right In case (a), which is an exothermic reaction, the energy of the transition state is closer in energy to that of the reactant than that of the intermediate or the product. Therefore, from the postulate, the structure of the transition state also more closely resembles that of the reactant. In case (b), the energy of the transition state is close to neither the reactant nor the product, making none of them a good structural model for the transition state.

Saccheri quadrilaterals were first considered by Omar Khayyam (1048-1131) in the late 11th century in Book I of Explanations of the Difficulties in the Postulates of Euclid. Unlike many commentators on Euclid before and after him (including of course Saccheri), Khayyam was not trying to prove the parallel postulate as such but to derive it from an equivalent postulate he formulated from "the principles of the Philosopher" (Aristotle): :Two convergent straight lines intersect and it is impossible for two convergent straight lines to diverge in the direction in which they converge.Boris A Rosenfeld and Adolf P Youschkevitch (1996), Geometry, p.467 in Roshdi Rashed, Régis Morelon (1996), Encyclopedia of the history of Arabic science, Routledge, .
The key idea of the many-worlds interpretation is that unitary quantum mechanics describes the whole universe. In particular, it describes a measurement as a unitary transformation, without using a collapse postulate, and describes observers as ordinary quantum-mechanical systems. This stands in sharp contrast to the Copenhagen interpretation, on which a measurement is a "primitive" concept, not describable by quantum mechanics, the universe is divided into a quantum and a classical domain, and the collapse postulate is central. MWI's main conclusion is that the universe (or multiverse in this context) is composed of a quantum superposition of an infinite or undefinable amount or number of increasingly divergent, non- communicating parallel universes or quantum worlds.
Prior to Einstein, it was thought that this speed was relative to a fixed medium, called the luminiferous ether. In contrast, the theory of special relativity postulates that light propagates at the speed of light in all inertial frames, and examines the implications of this postulate. All attempts to measure any speed relative to this ether failed, which can be seen as a confirmation of Einstein's postulate that light propagates at the same speed in all reference frames. Special relativity is a formalization of the principle of relativity that does not contain a privileged inertial frame of reference, such as the luminiferous ether or absolute space, from which Einstein inferred that no such frame exists.
The easiest way to show this is using the Euclidean theorem (equivalent to the fifth postulate) that states that the angles of a triangle sum to two right angles. Given a line \ell and a point P not on that line, construct a line, t, perpendicular to the given one through the point P, and then a perpendicular to this perpendicular at the point P. This line is parallel because it cannot meet \ell and form a triangle, which is stated in Book 1 Proposition 27 in Euclid's Elements.This argument assumes more than is needed to prove the result. There are proofs of the existence of parallels which do not assume an equivalent of the fifth postulate.
In retrospect, although Ahlquist was right in his ″one transmitter – two receptors″ postulate, he erred in the identification of the transmitter with adrenaline. There is an additional qualification. For many responses to sympathetic nerve stimulation, the ATP co-stored with noradrenaline (see above) is a cotransmitter. It acts through purinoceptors.
The ape was probably a quadruped. It is not possible to postulate on how O. macedoniensis used the trees but it seems likely that it did. O. macedoniensis's molar enamel cover was fairly thick and had low cusps. The male O. macedoniensis had large canine teeth with shearing lower premolars.
It was simpler and more convenient to postulate preformed miniature organisms that expanded in accordance with mechanical laws. So convincing was this explanation that some naturalists claimed to actually see miniature preformed animals (animalcules) in eggs and miniature plants in seeds. In the case of humans, the term homunculus was used.
Decreolization is a postulated phenomenon whereby over time a creole language reconverges with the lexifier from which it originally derived. The notion has attracted criticism from linguists who argue there is little theoretical or empirical basis on which to postulate a process of language change which is particular to creole languages.
The theoretical assumption of mathematical optimisation by agents in equilibrium is replaced by the less restrictive postulate of agents with bounded rationality adapting to market forces,• W. Brian Arthur, 1994. "Inductive Reasoning and Bounded Rationality," American Economic Review, 84(2), pp. 406-411 . • John H. Holland and John H. Miller (1991).
Mahwah, NJ: Lawrence Erlbaum. postulate for the transportation-imagery model. As Van Laer, de Ruyter, Visconti, and Wetzels elaborate further, narrative transportation occurs whenever the story receiver experiences a feeling of entering a world evoked by the narrative because of empathy for the story characters and imagination of the story plot.
Messages may not be properly received if too many messages or noise is interfering with reception of messages. # Serial Transmission Effect: This postulate refers to change of meaning within a message. This can occur when information is traveling through various people within a network. Messages are liable to get distorted.
A Mandelbrot set fractal The invariant set postulate concerns the possible relationship between fractal geometry and quantum mechanics and in particular the hypothesis that the former can assist in resolving some of the challenges posed by the latter. It is underpinned by nonlinear dynamical systems theory and black hole thermodynamics.
Structuralist mathematics goes further, and develops theories and axioms (e.g. field theory, group theory, topology, vector spaces) without any particular application in mind. The distinction between an "axiom" and a "postulate" disappears. The postulates of Euclid are profitably motivated by saying that they lead to a great wealth of geometric facts.
It is difficult to attribute a work so similar in style to Plato's to another person. Slings in his later work admittedly changed his thesis on the authorship and claimed that it is easier to accept as a work of Plato than to postulate an anonymous author similar to Plato's skill.
The first led to the conclusion that straight lines are finite, contradicting Euclid's second postulate. So Saccheri correctly rejected it. However, the principle is now accepted as the basis of elliptic geometry, where both the second and fifth postulates are rejected. The second possibility turned out to be harder to refute.
The hypotheses of the acute, the obtuse, and the right angle are now known to lead respectively to the non-Euclidean hyperbolic geometry of Gauss-Bolyai-Lobachevsky, to that of Riemannian geometry, and to Euclidean geometry.Rolwing, R. & Levine, M. (1969). ”The Parallel Postulate”. The Mathematics Teacher, 62(8), 665–669.
Thomas Gold, in a 1999 book, cited the discovery of thermophile bacteria in the Earth's crust as new support for the postulate that these bacteria could explain the existence of certain biomarkers in extracted petroleum. A rebuttal of biogenic origins based on biomarkers has been offered by Kenney, et al. (2001).
For examples, elliptic geometry (no parallels) and hyperbolic geometry (many parallels). Both elliptic and hyperbolic geometry are consistent systems, showing that the parallel postulate is independent of the other axioms.Harold Scott Macdonald Coxeter Non-Euclidean Geometry, pages 1-15 Proving independence is often very difficult. Forcing is one commonly used technique.
Low estimates postulate it to affect 30–100 million people worldwide, mainly in tropical and subtropical countries, while higher estimates conservatively extrapolate that infection is upwards to or above 370 million people. It belongs to the group of neglected tropical diseases, and worldwide efforts are aimed at eradicating the infection.
Individual stability of antisocial behavior from childhood to adulthood: Testing the stability postulate of Moffitt's developmental theory. Criminology, 41(3), 593-609. There is a difference in the continuity of antisocial behavior between men and women as well. In one longitudinal study an entire county's population was followed from age 8 to 48.
In 2014 she was one of the leaders in the detection of a possible hybrid star or Thorne–Żytkow object, which had been a theoretical postulate for years. This discovery involved the Magellan Telescopes. The chemical characteristics of this star, HV 2112, were studied using spectroscopy techniques, in which Morrell is an expert.
The truth of these complicated facts rests on the acceptance of the basic hypotheses. However, by throwing out Euclid's fifth postulate, one can get theories that have meaning in wider contexts (e.g., hyperbolic geometry). As such, one must simply be prepared to use labels such as "line" and "parallel" with greater flexibility.
At the center of Myrdal's work in An American Dilemma was his postulate that political and social interaction in the United States is shaped by an "American Creed". This creed emphasizes the ideals of individualism, civil liberties, and equality of opportunity.Myrdal, Gunnar (1944). An American dilemma: The negro problem and modern democracy.
Other mathematicians have devised simpler forms of this property. Regardless of the form of the postulate, however, it consistently appears more complicated than Euclid's other postulates: > 1\. To draw a straight line from any point to any point. 2\. To produce > [extend] a finite straight line continuously in a straight line. 3\.
The postulate of creation of Kingdoms of Halych and Polesia in the lands inhabited by large numbers of Ukrainians did not satisfy their interests in creation of an independent state. Paderewski did not pursue the matter due to large percentage of Ukrainian population living in those regions with a different politics and demography.
The five skandhas together compose consciousness. The "things" we are conscious of are "mere concepts", not noumenon. It took Chinese Buddhism several centuries to recognize that śūnyatā is not identical to "wu", nor does Buddhism postulate a permanent soul. The influence of those various doctrinal and textual backgrounds is still discernible in Zen.
Ancestral to the modern concept of a manifold were several important results of 18th and 19th century mathematics. The oldest of these was Non-Euclidean geometry, which considers spaces where Euclid's parallel postulate fails. Saccheri first studied this geometry in 1733. Lobachevsky, Bolyai, and Riemann developed the subject further 100 years later.
During his 2014 course, Hacking Consciousness, at Stanford University, he presented its mathematical framework. Subsequently, he describes with further mathematical detail his postulate that multiplicity including all matter arises from a primordial singularity of Consciousness through the spontaneous phenomenon of Consciousness actually exercising its basic nature of being conscious and thus knowing itself.
Communications of the ACM. 2010 Jun 1;53(6):149-53. The postulate that social influence constitutes of four overlapping phenomenon: # Social Computing Action: actions performed through use of technology such as Web browsers and cell phones. # Social Computing Consensus: agreement from all people that it is right to carry out the action.
Hammond's postulate is useful for understanding the relationship between the rate of a reaction and the stability of the products. While the rate of a reaction depends just on the activation energy (often represented in organic chemistry as ΔG‡ “delta G double dagger”), the final ratios of products in chemical equilibrium depends only on the standard free-energy change ΔG (“delta G”). The ratio of the final products at equilibrium corresponds directly with the stability of those products. Hammond's postulate connects the rate of a reaction process with the structural features of those states that form part of it, by saying that the molecular reorganizations have to be small in those steps that involve two states that are very close in energy.
In 1944, National Councillor Emil Oprecht requested in a postulate the introduction of women's suffrage, because important women's political issues were close to the political agenda of the day: old age and survivors' insurance, motherhood insurance, and family protection. The postulate was supported by the BSF with a petition of 6 February 1945 in the name of 38 women's alliances. The Swiss Women's Association for the Public Good (Schweizerische Gemeinnützige Frauenverein) did not express an opinion on the question; however, the Catholic Women's League (Katholische Frauenbund) departed from the conservative line of the Catholic church and gave its members a free voice. In 1945, the Swiss Action Committee for Women's Suffrage (Schweizerische Aktionskomitee für Frauenstimmrecht) was established as an opinion-forming instrument.

Grace presumes that proponents of the Mapping-view think of different languages as dividing up the same objective world into different categories, quite like different political maps divide up the same territory in different ways. The Reality-Construction-view on the other hand says that each language embodies a different conceptual construction of reality, which is a stronger claim than the Mapping-view's. One key difference between the two views is their attitude towards the postulate that "anything that can be said in one language can be said in any other language" , which translates as the claim that translation from one language to another is always possible. According to Grace, the Mapping-view accepts this postulate, while the Reality- Construction-view rejects it.
In an appendix to his book on mathematical existence, Becker set the problem of finding a formal calculus for intuitionistic logic. In a series of works in the early 1950s he surveyed modal, intuitionistic, probabilistic, and other philosophical logics. Becker made contributions to modal logic (the logic of necessity and possibility) and Becker’s postulate, the claim that modal status is necessary (for instance that the possibility of P implies the necessity of the possibility of P, and also the iteration of necessity) is named for him. Becker's Postulate later played a role in the formalization given, by Charles Hartshorne, the American process theologian, of the Ontological Proof of God's existence, stimulated by conversations with the logical positivist and opponent of the alleged proof, Rudolf Carnap.
If the sum of the interior angles α and β is less than 180°, the two straight lines, produced indefinitely, meet on that side. Euclid's parallel postulate states: > If a line segment intersects two straight lines forming two interior angles > on the same side that sum to less than two right angles, then the two lines, > if extended indefinitely, meet on that side on which the angles sum to less > than two right angles.George Phillips (1826) Elements of Geometry > (containing the first six books of Euclid), p. 3, Baldwin, Cradock, and Joy The complexity of this statement when compared to Playfair's formulation is certainly a leading contribution to the popularity of quoting Playfair's axiom in discussions of the parallel postulate.
Indeed, making these estimates quantitative, one obtains that this argument is valid for all n \ge 468. The remaining smaller values of n are easily settled by direct inspection, completing the proof of Bertrand's postulate. This proof is so short and elegant that it is considered to be one of the Proofs from THE BOOK.
He describes evolution theory as "viscid, asphyxiating baggage" that requires "blind religious faith",Concise Atlas of the Butterflies of the World, Bernard d'Abrera, Hill House Publishers, Melb.& Lond., 2001, . He believed it cannot be tested or demonstrated in any natural frame of reference, and therefore it may not be considered even a scientific postulate.
As one can postulate tests that could be applied, given enough time and space, then these ideas should be seen as scientific hypotheses. These are conjectures and perhaps can only be considered as social and maybe political philosophy; they may have implications for theology, or thealogy as Zell- Ravenheart and Isaac Bonewits put it.
She showed that an argument could be valid and ground-consequent even if its propositions were generated via physical cause and effect by non- rational factors.The Socratic Digest, No. 4 (1948) Similar to Anscombe, Richard Carrier and John Beversluis have written extensive objections to the argument from reason on the untenability of its first postulate.
This relation is attributed to Max Born (1925), who called it a "quantum condition" serving as a postulate of the theory; it was noted by E. Kennard (1927) to imply the Heisenberg uncertainty principle. The Stone–von Neumann theorem gives a uniqueness result for operators satisfying (an exponentiated form of) the canonical commutation relation.
I contend this is made possible by the method's loosely > defined rules and the ability to postulate a large number of nested waves of > varying magnitude.

The scholars interviewed postulate that the South had need for a scapegoat in the wake of the Civil War and that Sherman was the easiest target. For his part, Sherman is stated to have seen himself as only doing his duty and that he did not care what people said about him one way or the other.
The reactivity order is (CH3)3C- > (CH3)2CH- > CH3CH2- > CH3-. Unimolecular Elimination Reaction Coordinate Furthermore, studies describe a typical kinetic resolution process that starts out with two enantiomers that are energetically equivalent and, in the end, forms two energy-inequivalent intermediates, referred to as diastereomers. According to Hammond's postulate, the more stable diastereomer is formed faster.

Medieval Buddhist atomism, flourishing in ca. the 7th century, was very different from the atomist doctrines taught in early Buddhism. Medieval Buddhist philosophers Dharmakirti and Dignāga considered atoms to be point- sized, durationless, and made of energy. In discussing the two systems, Fyodor Shcherbatskoy (1930) stresses their commonality, the postulate of "absolute qualities" (guna-dharma) underlying all empirical phenomena.
Equivalent to the original? Yes. According to some references, the theory of special relativity can be derived from a single postulate: the principle of relativity. This claim can be misleading because actually these formulations rely on various unsaid assumptions such as isotropy and homogeneity of space. The question here is not about the exact number of postulates.
An axiom or postulate is a statement that is taken to be true, to serve as a premise or starting point for further reasoning and arguments. The word comes from the Greek axíōma () 'that which is thought worthy or fit' or 'that which commends itself as evident.'Cf. axiom, n., etymology. Oxford English Dictionary, accessed 2012-04-28.
Unlike "magisterial poetry" (where metaphors and pretty language are used to describe the familiar), "pupillary poetry" uses poetic imagery to assist a scientist's thinking about the exotic (e.g. consider "being" an electron temporarily). Although it is useful, some authors take pupillary poetry too far, and, "drunk on metaphor", they produce "bad science"; i.e. postulate faulty theories.
The tectonic development of collapsed mountain belts is heavily debated. Some argue that delamination causes a second uplift along with crustal thickening, heating and volcanism. Others argue that delamination causes collapse and thinning of the crust. Some researchers postulate that the Sierra Nevada (California), Basin and Range Province and Colorado Plateau in the western USA exemplify this.
Volcanism in this field appears to be related to volcanism which is widespread in this part of Asia. Localized asthenosphere upwellings may be responsible for these volcanic events at Hangai and other volcanic centres around Lake Baikal. Other theories for the Hangai postulate a mantle plume or the removal of part of the lithosphere by asthenospheric currents.
The evidence suggests that early humans probably used the modified tools for hunting or cutting meat from killed animals. Researchers postulate that this may have been the first time that a bow and arrows were used for hunting, an advancement that had a significant impact on how early humans may have lived, hunted, and existed as community groups.
In classical thermodynamics, the second law is a basic postulate applicable to any system involving heat energy transfer; in statistical thermodynamics, the second law is a consequence of the assumed randomness of molecular chaos. There are many versions of the second law, but they all have the same effect, which is to express the phenomenon of irreversibility in nature.
"Not Final!" is a science fiction short story by American writer Isaac Asimov, originally published in the October 1941 issue of Astounding Science Fiction, and included in the 1972 collection The Early Asimov. Its sequel, "Victory Unintentional", is a robot story. These are two of the few stories by Asimov to postulate non-human intelligences in the Solar system.
These equivalent statements include: # There is at most one line that can be drawn parallel to another given one through an external point. (Playfair's axiom) # The sum of the angles in every triangle is 180° (triangle postulate). # There exists a triangle whose angles add up to 180°. # The sum of the angles is the same for every triangle.
He may see the rate of change of position as apparently representing motion faster than c when calculated, like the edge of a shadow across a curved surface. This is a different signal, containing different information, to the pulse and does not break the second postulate of special relativity. c is strictly maintained in all local fields.
He was also a writer for "Poesía Magazine" and a judge for the ACE Awards. Johann Wolfgang von Goethe and Albert Schweitzer were influences on Peter Bloch's formation. He used to refer to Goethe as the poet of German thought. He embraced Schweitzer's postulate that civilization and culture are the same - that culture is an ethical value.
The diagnosis is made by blood and stool tests. The medication ivermectin is widely used to treat strongyloidiasis. Strongyloidiasis is a type of soil- transmitted helminthiasis. Low estimates postulate it to affect 30–100 million people worldwide, mainly in tropical and subtropical countries, while higher estimates conservatively extrapolate that infection is upwards to or above 370 million people.
In physics, EP quantum mechanics is a theory of motion of point particles, partly included in the framework of quantum trajectory representation theories of quantum mechanics, based upon an equivalence postulate (EP) similar in content to the equivalence principle of general relativity, rather than on the traditional Copenhagen interpretation of quantum mechanics. The equivalence postulate states that all one-particle systems can be connected by a non- degenerate coordinate transformation, more precisely by a map over the cotangent bundle of the position manifold, so that there exists a quantum action function S(q) that transforms as a scalar field. Here, the action defined as :d S(q) = p_i(q) dq^i is the canonical one-form. This property lies at the heart of the EP formulation of quantum mechanics.
What was new here was just the label 'zeroth law of thermodynamics'. Fowler, with co-author Edward A. Guggenheim, wrote of the zeroth law as follows: ::...we introduce the postulate: If two assemblies are each in thermal equilibrium with a third assembly, they are in thermal equilibrium with each other. They then proposed that "it may be shown to follow that the condition for thermal equilibrium between several assemblies is the equality of a certain single-valued function of the thermodynamic states of the assemblies, which may be called the temperature t, any one of the assemblies being used as a "thermometer" reading the temperature t on a suitable scale. This postulate of the "Existence of temperature" could with advantage be known as the zeroth law of thermodynamics".
The exterior angle theorem is Proposition 1.16 in Euclid's Elements, which states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles. This is a fundamental result in absolute geometry because its proof does not depend upon the parallel postulate. In several high school treatments of geometry, the term "exterior angle theorem" has been applied to a different result, namely the portion of Proposition 1.32 which states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles. This result, which depends upon Euclid's parallel postulate will be referred to as the "High school exterior angle theorem" (HSEAT) to distinguish it from Euclid's exterior angle theorem.
Metaphysics continues asking "why" where science leaves off. For example, any theory of fundamental physics is based on some set of axioms, which may postulate the existence of entities such as atoms, particles, forces, charges, mass, or fields. Stating such postulates is considered to be the "end" of a science theory. Metaphysics takes these postulates and explores what they mean as human concepts.
Factor analysis is a statistical test that is used to find relationships between multiple correlated measures and Spearman played a clear part in its development. Spearman coined the term factor analysis and used it extensively in analyzing multiple measures of cognitive performance. It was factor analytic data which led Spearman to postulate his original general and specific factor models of ability.Spearman, C. (1950).
Despite not having her family with her in Hawai'i, Lai had a vibrant social life with close friends and involvement in activities such as dances, parties, baseball games, and vacations. Scholars postulate that this social involvement, along with her professional progress and ability to "reside openly in an integrated community," may have been some reasons why Lai decided to remain in Hawai'i.
Consider a physical system moving through Minkowski spacetime. Assume that there is at any moment an inertial system such that in it, the system is at rest. This assumption is sometimes called the third postulate of relativity. This means that at any instant, the coordinates and state of the system can be Lorentz transformed to the lab system through some Lorentz transformation.
It took Chinese Buddhism several centuries to recognize that sunyata does not refer to "wu", nothingness, nor does Buddhism postulate an undying soul. The influence of those various doctrinal and textual backgrounds is still discernible in Zen. Zen teachers still refer to Buddha-nature, but the Zen tradition also emphasizes that Buddha-nature is sunyata, the absence of an independent and substantial self.
Dolukhanov and others (2005) pages 1453–1457. The pottery was used in intensive food gathering. The rate at which it spread was no faster than the spread of the Neolithic in general. Accordingly, Dolukhanov and others postulate that an impulse from the steppe to the southeast of the barrier stimulated the Mesolithics north of it to innovate their own pottery.
One theory is that exercise is stimulating the release of mediators such as histamine from IgE-activated mast cells. Two of the reviews postulate that exercise is not essential for the development of symptoms, but rather that it is one of several augmentation factors, citing evidence that the culprit food in combination with alcohol or aspirin will result in a respiratory anaphylactic reaction.
Due lettioni, 1613 Pietro Antonio Cataldi (15 April 1548, Bologna – 11 February 1626, Bologna) was an Italian mathematician. A citizen of Bologna, he taught mathematics and astronomy and also worked on military problems. His work included the development of continued fractions and a method for their representation. He was one of many mathematicians who attempted to prove Euclid's fifth postulate.
In what can be considered the first reputable textbook in the field of Organizational Communication, Communication Within an Organization: The Interpretive Review of Theory and Research, Redding discusses Ten Postulates of Organizational Communication.Redding, W. Charles. Communication Within the Organization: The Interpretive Review of Theory and Research (pp. 27-138) # Meanings are not transferred: This postulate refers more to the receptiveness of the receivers.
They discover that there is a Nazi base on the Moon. They bomb it from their captured ship and land. One survivor is found, revived, and questioned. The boys also find evidence of an ancient lunar civilization, and postulate that the craters of the Moon were formed not by impacts from space, but by nuclear bombs that destroyed the alien race.
Social Science Quarterly, 1993, 74, 783–92. From their study, Schulte and colleagues postulate that "it may be counter productive in that individuals are driving farther under the influence of alcohol, thus, increasing their exposure to crashes in dry counties."Schulte, G., et al. "Consideration of driver home county prohibition and alcohol- related vehicle crashes". Accident Analysis & Prevention, 1993, 35(5), 641–48.
Excerpt available online The Morris and Whitcomb position is distinct from Seventh-day Adventism because they postulate both a young earth and a young universe. About the time that The Genesis Flood was having a large impact in the evangelical world, a number of progressive Adventist scholars educated in secular universities began promoting Theistic Evolution.see Creation Reconsidered ed. James L. Hayward.
It was described in 2009 by Wagner and Lehman in 2009. The type species is A. daviesi, named for Kyle L. Davies, who in 1983 was the first to postulate the presence of a lambeosaurine in the Aguja Formation. As a hadrosaurid, Angulomastacator would have been a bipedal/quadrupedal herbivore, eating plants with sets of ever-replacing teeth stacked on each other.
Such a hypothesis was termed a postulate. While the axioms were common to many sciences, the postulates of each particular science were different. Their validity had to be established by means of real-world experience. Indeed, Aristotle warns that the content of a science cannot be successfully communicated, if the learner is in doubt about the truth of the postulates.
It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms.Lieb, E.H., Yngvason, J. (1999).
He then distinguished between the stocks (£250m) and the flows yielding from them (£15m). The discrepancy between these flows and his estimate for national income (£40m) leads Petty to postulate that the other £25m is the yield from what must be £417m of labour stock, the "value of the people". This gave a total wealth for England in the 1660s of £667m.
They went on to postulate that a larger brain would allow for more complex foraging behavior, which would result in a higher quality diet, which would then allow the gut to shrink further, freeing up more energy for the brain. This research also presented a case for studying the evolution of organs in a more interconnected manner, rather than in isolation.
They were covered in bark. Ceremonial buildings, however, were usually thatched with reeds and bullgrass. The people held ceremonial dances, tribal meetings, and other important rites in these council houses. There is uncertainty concerning the time of the tribe's disbanding: historians Peter Moore and William Ramsey postulate that they disbanded immediately following the Yamasee War against English colonists of the early 18th century.
In 1999, Zimmermann and four other teenagers founded the youth party PETO – Die junge Alternative (PETO - the young alternative). The name of the party refers to the Latin word peto (in English: „I postulate“).Handelsblatt: Kommunalwahl NRW – Monheim, oder: Wo jetzt die Jungend regiert. (German), retrieved on 1 September 2009 Zimmermann became first president of this new party until 2004.
De Moivre wrote a book on probability theory, The Doctrine of Chances, said to have been prized by gamblers. De Moivre first discovered Binet's formula, the closed- form expression for Fibonacci numbers linking the nth power of the golden ratio φ to the nth Fibonacci number. He also was the first to postulate the central limit theorem, a cornerstone of probability theory.
A coordinative definition is a postulate which assigns a partial meaning to the theoretical terms of a scientific theory by correlating the mathematical objects of the pure or formal/syntactical aspects of a theory with physical objects in the world. The idea was formulated by the logical positivists and arises out of a formalist vision of mathematics as pure symbol manipulation.
In philosophy of science, dark energy is an example of an "auxiliary hypothesis", an ad hoc postulate that is added to a theory in response to observations that falsify it. It has been argued that the dark energy hypothesis is a conventionalist hypothesis, that is, a hypothesis that adds no empirical content and hence is unfalsifiable in the sense defined by Karl Popper.
Many scientists postulate that wormholes are merely projections of a fourth spatial dimension, analogous to how a two- dimensional (2D) being could experience only part of a three-dimensional (3D) object. A wormhole could connect extremely long distances such as a billion light years or more, short distances such as a few meters, different universes, or different points in time.
Higher-order theories of consciousness postulate that consciousness consists in perceptions or thoughts about first-order mental states. In particular, phenomenal consciousness is thought to be higher-order representation of perceptual or quasi-perceptual contents, such as visual images. Higher-order theories are distinguished from other cognitive/representational accounts of consciousness which suggest that merely first-order mentality of certain sorts constitutes consciousness.
The standard nontunnelling approach to KIEs is developed from Westheimer and Lars Melander. The Melander-Westheimer postulate has successfully predicted the ways in which KIEs and transition state (TS) structures vary. Westheimer introduced the idea of photoaffinity labeling of the active site of proteins. The identification of the "active sites" of an enzyme is difficult in cases where proteins have hydrocarbon-rich sites.
One of the main weaknesses of the disposable soma theory is that it does not postulate any specific cellular mechanisms to which an organism shifts energy to somatic repair over reproduction. Instead, it only offers an evolutionary perspective on why aging may occur due to reproduction. Therefore, parts of it are rather limited outside of the field of evolutionary biology.
They also postulate the existence of a quantity named entropy, which can be defined for any system. In thermodynamics, interactions between large ensembles of objects are studied and categorized. Central to this are the concepts of system and surroundings. A system is composed of particles, whose average motions define its properties, which in turn are related to one another through equations of state.
William of Ockham emphasised the principle of parsimony: natural philosophers should not postulate unnecessary entities, so that motion is not a distinct thing but is only the moving objectEdward Grant, A Source Book in Medieval Science, (Harvard Univ. Press, 1974), p. 232 and an intermediary "sensible species" is not needed to transmit an image of an object to the eye.
However, some astronomers postulate that close binary central stars might be responsible for the more complex and extreme planetary nebulae. Several have been shown to exhibit strong magnetic fields, and their interactions with ionized gas could explain some planetary nebulae shapes. There are two main methods of determining metal abundances in nebulae. These rely on recombination lines and collisionally excited lines.
The dynasty has been staunchly Brahminist and had attempted to restore Brahminism to Bengal. They also established the system of kulinism in Bengal; through which higher caste males could take lower caste brides and enhance the status of these women's children. Some postulate that the dynasty's suppression of Buddhism became a cause for the conversions to Islam, especially in eastern Bengal.
This postulate is a subset of the postulates that underlie Maxwell's equations in the interpretation given to them in the context of special relativity. However, Maxwell's equations rely on several other postulates, some of which are now known to be false (e.g., Maxwell's equations cannot account for the quantum attributes of electromagnetic radiation). The second postulate can be used to imply a stronger version of itself, namely that the spacetime interval is invariant under changes of inertial reference frame. In the above notation, this means that :c^2 (s-t)^2 - (x_1-y_1)^2 - (x_2-y_2)^2 - (x_3-y_3)^2 := c^2 (s'-t')^2 - (x'_1-y'_1)^2 - (x'_2-y'_2)^2 - (x'_3-y'_3)^2 for any two events A, B. This can in turn be used to deduce the transformation laws between reference frames; see Lorentz transformation.
Consumer theory is therefore based on generating refutable hypotheses about the nature of consumer demand from this behavioral postulate. In order to reason from the central postulate towards a useful model of consumer choice, it is necessary to make additional assumptions about the certain preferences that consumers employ when selecting their preferred "bundle" of goods. These are relatively strict, allowing for the model to generate more useful hypotheses with regard to consumer behavior than weaker assumptions, which would allow any empirical data to be explained in terms of stupidity, ignorance, or some other factor, and hence would not be able to generate any predictions about future demand at all. For the most part, however, they represent statements which would only be contradicted if a consumer was acting in (what was widely regarded as) a strange manner.
In the list above, it is always taken to refer to non-intersecting lines. For example, if the word "parallel" in Playfair's axiom is taken to mean 'constant separation' or 'same angles where crossed by any third line', then it is no longer equivalent to Euclid's fifth postulate, and is provable from the first four (the axiom says 'There is at most one line...', which is consistent with there being no such lines). However, if the definition is taken so that parallel lines are lines that do not intersect, or that have some line intersecting them in the same angles, Playfair's axiom is contextually equivalent to Euclid's fifth postulate and is thus logically independent of the first four postulates. Note that the latter two definitions are not equivalent, because in hyperbolic geometry the second definition holds only for ultraparallel lines.
CAN NEGLIGENCE & INTENTION OVERLAP? In S v Ngubane, Jansen JA stated that "dolus postulates foreseeing, but culpa does not necessarily postulate not foreseeing. A man may foresee the possibility of harm and yet be negligent in respect of that harm ensuing." Prior to Ngubane, there had been a conflict in both academic and judicial opinion about whether dolus (intention) and culpa (negligence) were mutually exclusive concepts.
His fresh theoretical proof was and still is considered by some writers to be invalid. But more importantly, it relied on a new theoretical postulate of "perfectly black bodies," which is the reason why one speaks of Kirchhoff's law. Such black bodies showed complete absorption in their infinitely thin most superficial surface. They correspond to Balfour Stewart's reference bodies, with internal radiation, coated with lamp-black.
The distinction between "acts of thought" (noesis) and "intentional objects of thought" (noema) does not seem, therefore, to constitute an irreducible ground. It appears rather at a higher level of analysis. Thus, Merleau-Ponty does not postulate that "all consciousness is consciousness of something", which supposes at the outset a noetic-noematic ground. Instead, he develops the thesis according to which "all consciousness is perceptual consciousness".
Gnostic systems postulate a dualism between God and the world,Hans Jonas, The Gnostic Religion, p. 42, Beacon Press, 1963, ; 1st ed. 1958 varying from the "radical dualist" systems of Manichaeism to the "mitigated dualism" of classic gnostic movements. Radical dualism, or absolute dualism, posits two co-equal divine forces, while in mitigated dualism one of the two principles is in some way inferior to the other.
Equivalence here means that in the presence of the other axioms of the geometry each of these theorems can be assumed to be true and the parallel postulate can be proved from this altered set of axioms. This is not the same as logical equivalence.An appropriate example of logical equivalence is given by Playfair's axiom and Euclid I.30 (see Playfair's axiom#Transitivity of parallelism).
The concept has its roots in a notion expressed by F. L. Wachter in 1816 in a letter to his teacher Gauss. Noting that in Euclidean geometry the limit of a sphere as its radius tends to infinity is a plane, Wachter affirmed that even if the fifth postulate were false, there would nevertheless be a geometry on the surface identical with that of the ordinary plane.
OOHDM (Object Oriented Hypermedia Design Method) is a method for the development of Web applications. It was one of the first methods to postulate the separation of concerns that defines its various models - requirements, conceptual, navigation, abstract interface and implementation. OOHDM, and its successor, SHDM (Semantic Hypermedia Design Method, which uses Semantic Web models) are supported by an open source, freely available environment, HyperDE.
The work is an epic poem, comprising 6,575 verses of hexameter in Homeric Greek, with parallel translation into Czech hexameter. The postmodern science fiction story is inspired by the philosophical postulate of quantum physics, that for something to exist it must be observed. The Watcher over the Cosmos turns out to be a certain sheep. To kill the sheep would mean the end of everything.
The marriage was completed by proxy on 25 January 1503 at Richmond Palace. Patrick, Earl of Bothwell, was proxy for the Scottish King and wore a gown of cloth-of-gold at the ceremony in the Queen's great chamber. He was accompanied by the Archbishop of Glasgow and Andrew Forman, Postulate of Moray. The herald, John Young, reported that "right notable jousts" followed the ceremony.
This can be considered the central postulate of musical set theory. In practice, set-theoretic musical analysis often consists in the identification of non-obvious transpositional or inversional relationships between sets found in a piece. Some authors consider the operations of complementation and multiplication as well. The complement of set X is the set consisting of all the pitch classes not contained in X .
Once operationalized, you have a concrete representation of a sociological concept. In addition to the basic levels of sociological abstraction, sociological concepts are often understood at multiple levels as a result of sociological theorizing. Sociological theories postulate relationships between sociological concepts. It is generally understood that there are three levels of sociological theorizing: The most abstract level of sociological theory is often referred to as Grand Theory.
Minkowski diagram for 3 coordinate systems. For the speeds relative to the system in black and holds. Another postulate of special relativity is the constancy of the speed of light. It says that any observer in an inertial reference frame measuring the vacuum speed of light relative to themself obtains the same value regardless of his own motion and that of the light source.
The general proportions of the various bones of the lowland kagu are very similar to those of the kagu. They differ in the greater size of the extinct species in averaging about 15% larger, with no overlap between the hindlimb elements and only rare overlap between those of the wings. The describers postulate that R. orarius and R. jubatus were lowland and highland forms, respectively.
On June 19, 1926, the Albertine Sisters' leadership met with Prince-Bishop Adam Stefan Sapieha as part of the approval process for the Congregation. Three days later, Sapieha approved the Sisters a congregation of diocesan right. On June 15, 1928, the Sisters established a new motherhouse in Kraków. It held a large chapel, and a postulate and novitiate for young entrants to the Congregation.
The program is meant as a benefit to the volunteer, and not only as a benefit to the people that the volunteer is supposed to work with. Regulations postulate that the volunteer can not occupy a job position that would otherwise be filled by a salaried employee. Volunteers participate in projects that are highly useful, such as working with disabled people or for various NGOs.
In formal semantics and philosophy of language, a meaning postulate is a way of stipulating a relationship between the meanings of two or more words. They were introduced by Rudolf Carnap as a way of approaching the analytic/synthetic distinction. Subsequently, Richard Montague made heavy use of meaning postulates in the development of Montague grammar, and they have features prominently in formal semantics following in Montague's footsteps.
Among his own designs are the Ship Tavern in the Brown Palace Hotel, a nautical-themed pub that he designed in celebration of the repeal of ProhibitionThomas Jacob Noel and John Fielder, Colorado, 1870-2000, Revisited: The History Behind the Images, Englewood, Colorado: Westcliffe, 2001, , p. 23. and the Sisters of Charity Postulate chapel in the Seton Center.Stained Glass 65/66 (1970) p. 16.
102Michel Foucault [1961] The History of Madness, Routledge 2006, pp. 490–1, 507–8, 510–1 Deleuze and Guattari added that "the familialism inherent in psychoanalysis doesn't so much destroy classical psychiatry as shine forth as the latter's crowning achievement", and that since the 19th century, the study of mental illnesses and madness has remained the prisoner of the familial postulate and its correlates.
Through Fire and Water: The Life of Reb Noson of Breslov. (Breslov Research Institute, New York/Jerusalem, no date listed), pp. 31-32. The Shpoler Zeide saw Rebbe Nachman's teachings as deviating from classical Judaism and from the teachings of the Baal Shem Tov. Some postulate that the Zeide felt threatened because Rebbe Nachman was moving in on his territory and taking disciples away from him.
This theory was postulated by Yanagita Kunio to explain the existence of some words in cultural centers, such as the capital of Japan, during various stages of the nation's history, and the lack of those such words in non-cultural centers. It is not certain if his postulate was the first to describe such cultural patterns in general; or merely with respect to language.
He was one of the ministers of Pastrana's administration with a popular positive image. After serving as minister he was proposed running for president but he declined. Garzon then participated as member of the facilitating Commission for the Humanitarian Accord with the Revolutionary Armed Forces of Colombia guerrilla group (FARC). He then resigned from the commission to postulate his name for Governor of Valle del Cauca Department.
Aerial view of the cathedral. Later some historians postulate that the Roman fort of Varae sat on the site of the cathedral. However, the city is believed to have developed around a 6th-century Celtic monastery founded by Saint Kentigern, and is now home to the small 14th century St Asaph Cathedral. This is dedicated to Saint Asaph (also spelt in Welsh as Asaff), its second bishop.
In the "Death in Damascus" scenario, an anthropomorphic "Death" predicts where you will be tomorrow, and goes to wait for you there. As in Newcomb's problem, we postulate that Death is a reliable predictor. A CDT agent would be unable to process the correlation, and may as a consequence make irrational decisions:Meacham, Christopher JG. "Binding and its consequences." Philosophical studies 149.1 (2010): 49-71.
Many of these advancements continue to be the underpinnings of non-relativistic technologies in the modern world. He used the Latin word gravitas (weight) for the effect that would become known as gravity, and defined the law of universal gravitation. Newton's postulate of an invisible force able to act over vast distances led to him being criticised for introducing "occult agencies" into science.Edelglass et al.
The sum of the measures of the interior angles of a triangle in Euclidean space is always 180 degrees. This fact is equivalent to Euclid's parallel postulate. This allows determination of the measure of the third angle of any triangle, given the measure of two angles. An exterior angle of a triangle is an angle that is a linear pair (and hence supplementary) to an interior angle.
According to Paraskeva (2010), at least 68% of American households play video games. Many recent research articles postulate education and gaming can be joined to provide academic benefits. According to Van Eck (2006), there are three reasons why games are considered learning tools: 1. Ongoing research that has included the last 20 years of educational findings have proven that digital games can be educational; 2.
The size of these "packets" of energy, which would later be named photons, was to be the same as Planck's "energy element", giving the modern version of the Planck–Einstein relation: :E = hf . Einstein's postulate was later proven experimentally: the constant of proportionality between the frequency of incident light f and the kinetic energy of photoelectrons E was shown to be equal to the Planck constant h.
The Phase I study showed that doses up to 1000 mg of Abituzumab, cetuximab, and irinotecan were well tolerated. The results of Phase II showed that the primary endpoint of progression-free survival was not met, but overall survival improved in patients receiving Abituzumab compared to standard of care. The researchers postulate that this could be due to increased expression of αvβ6 integrin in tumors.
In the 1980s, the economists Daniel Khazzoom and Leonard Brookes independently put forward ideas about energy consumption and behavior that argue that increased energy efficiency paradoxically tends to lead to increased energy consumption. In 1992, the US economist Harry Saunders dubbed this hypothesis the Khazzoom–Brookes postulate, and showed that it was true under neo- classical growth theory over a wide range of assumptions.
Geometry of Time and Space, Cambridge University Press, Cambridge UK. Max Jammer writes "the Einstein postulate ... opens the way to a straightforward construction of the causal topology ... of Minkowski space."Jammer, M. (1982). 'Einstein and quantum physics', pp. 59–76 in Albert Einstein: Historical and Cultural Perspectives; the Centennial Symposium in Jerusalem, edited by G. Holton, Y. Elkana, Princeton University Press, Princeton NJ, , p. 61.
Adapting the newer methods of historical research in the United States, the United Kingdom and France, researchers used disciplines such as historical demographics and ecology to support their work. Inspired by the Annales School, the postulate of "total history" – a comprehensive view of history aiming to understand long-term structures instead of explaining the current state of affairs – is now well- established in Swiss historiography.
The ring of invariants of binary septics is anomalous and has caused several published errors. Cayley claimed incorrectly that the ring of invariants is not finitely generated. gave lower bounds of 26 and 124 for the number of generators of the ring of invariants and the ring of covariants and observed that an unproved "fundamental postulate" would imply that equality holds. However showed that Sylvester's numbers are not equal to the numbers of generators, which are 30 for the ring of invariants and at least 130 for the ring of covariants, so Sylvester's fundamental postulate is wrong. and showed that the algebra of invariants of a degree 7 form is generated by a set with 1 invariant of degree 4, 3 of degree 8, 6 of degree 12, 4 of degree 14, 2 of degree 16, 9 of degree 18, and one of each of the degrees 20, 22, 26, 30.
Linguistic authorities affirm that the name Waberthwaite was originally Old Norse Veiðr buð þveit, meaning hunting or fishing booth clearing. Earliest spellings of the name (from 12th and 13th century documents) such as Waythebuthwayt and Wayburthwayt are consistent with the Old Norse origin. An alternative postulate that the name is connected with the Wyberg family who later settled in St Bees, Clifton and Isel has been strongly refuted by Mary Fair.
Historically, classical mechanics had been around for nearly a quarter century before quantum mechanics developed. Classical mechanics originated with Isaac Newton's laws of motion in Philosophiæ Naturalis Principia Mathematica, developed over the seventeenth century. Quantum mechanics developed later, over the nineteenth century, precipitated by Planck's postulate and Albert Einstein's explanation of the photoelectric effect. Both fields are commonly held to constitute the most certain knowledge that exists about physical nature.
Azotobacter vinelandii is a nitrogen-fixing bacteria which is known by its high respiratory rate among aerobic organisms. Some physiological studies postulate that cytochrome d functions as a terminal oxidase in the membranes of this organism, taking part in the electron transport system. The studies characterized the different genes in the two subunits (, ; third subunit ). A very extensive homology with CydAB of the E. coli was found in these studies.
There is no fixed axiom set for geometry, as more than one consistent set can be chosen. Each such set may lead to a different geometry, while there are also examples of different sets giving the same geometry. With this plethora of possibilities, it is no longer appropriate to speak of "geometry" in the singular. Historically, Euclid's parallel postulate has turned out to be independent of the other axioms.
However, discrepancies were found in the results of the experiment: the observed horizontal distances disagreed with the calculated distances expected for a constant rate of acceleration. Galileo attributed the discrepancies to air resistance in the unreported experiment, and friction in the inclined plane experiment. These discrepancies forced Galileo to assert that the postulate held only under "ideal conditions," i.e., in the absence of friction and/or air resistance.
Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) primarily occurs in adults (with a mean age of 27). Symptoms include blurred vision in both eyes, but the onset may occur at a different time in each eye. There are yellow-white placoid lesions in the posterior pole at the level of the RPE. Some suggest a genetic predisposition to the disease, while others postulate an abnormal immune response to a virus.
Many people believe that Ieyasu met Okaji around the time he first settled in Edo. Due to her status as his concubine, her age when they met is not recorded but some historians postulate that she could have been in her early teens. The two met due to her older brother reaching a higher status. She was admired by Tenkai, a Buddhist monk and political advisor from Ieyasu.
Einstein based his theory of special relativity on two fundamental postulates. First, all physical laws are the same for all inertial frames of reference, regardless of their relative state of motion; and second, the speed of light in free space is the same in all inertial frames of reference, again, regardless of the relative velocity of each reference frame. The Lorentz transformation is fundamentally a direct consequence of this second postulate.
Compression based methods postulate that the optimal segmentation is the one that minimizes, over all possible segmentations, the coding length of the data.Shankar Rao, Hossein Mobahi, Allen Yang, Shankar Sastry and Yi Ma Natural Image Segmentation with Adaptive Texture and Boundary Encoding , Proceedings of the Asian Conference on Computer Vision (ACCV) 2009, H. Zha, R.-i. Taniguchi, and S. Maybank (Eds.), Part I, LNCS 5994, pp. 135–146, Springer.
Max Tegmark's mathematical universe hypothesis (or mathematicism) goes further than Platonism in asserting that not only do all mathematical objects exist, but nothing else does. Tegmark's sole postulate is: All structures that exist mathematically also exist physically. That is, in the sense that "in those [worlds] complex enough to contain self-aware substructures [they] will subjectively perceive themselves as existing in a physically 'real' world".Tegmark (1998), p. 1.
They argue that there is no need to postulate a maker for the world, just as there is no need for an author to compose the Vedas or a god to validate the rituals. Mimamsa argues that the gods named in the Vedas have no existence apart from the mantras that speak their names. In that regard, the power of the mantras is what is seen as the power of gods.
Eratosthenes was also the first Greek author to postulate an island Taprobane at the far south of India, later becoming a name of Sri Lanka. European knowledge of the geography of India did not become much better resolved until the end of Antiquity, and remained at this stage throughout the Middle Ages, only becoming more detailed with the beginning of the Age of Sail in the 15th century.

In 1913 Rothe married and began to teach mathematics at the Vienna University of Technology as Professor extraordinarius, and from 1920 as Professor ordinarius. In 1923 he died after a long disease. Rothe is known for his collaboration (1910-1912) with Philipp Frank on special relativity. Based on group theory, they tried to derive the Lorentz transformation without the postulate of the constancy of the speed of light.
This is the sense in which universal lightspeed can be deduced rather than postulated. For some historical information, see: History of special relativity#Spacetime physics and the section "Lorentz transformation without second postulate" for the approaches of Ignatowski and Frank/Rothe. However, according to Pauli (1921), Resnick (1967), and Miller (1981), those models were insufficient. But the constancy of the speed of light is contained in Maxwell's equations.
None of the Latin manuscripts of the hagiography of Leo Luke refer to an original Greek source. However the presence of Greek anthroponyms (such as Leone, Teotiste, Christopher, Teodoro, Eutimio) may postulate an original source in Greek. The hagiography was likely composed immediately after the death of the saint in Calabria, but may have been passed down orally and then in writing at a later date and in another place.
Logical axioms are usually statements that are taken to be true within the system of logic they define and are often shown in symbolic form (e.g., (A and B) implies A), while non-logical axioms (e.g., ) are actually substantive assertions about the elements of the domain of a specific mathematical theory (such as arithmetic). When used in the latter sense, "axiom", "postulate", and "assumption" may be used interchangeably.
For this reason, an isolated system, initially not its own state of internal thermal equilibrium, but left for a long time, practically always will reach a final state which may be regarded as one of internal thermal equilibrium. Such a final state is one of spatial uniformity or homogeneity of temperature.Planck, M., (1897/1903), p. 3. The existence of such states is a basic postulate of classical thermodynamics.
In relativistic cosmology, Weyl's postulate stipulates that in a fluid cosmological model, the world lines of the fluid particles, which act as the source of the gravitational field and which are often taken to model galaxies, should be hypersurface orthogonal. That is, the world lines should be everywhere orthogonal to a family of spatial hyperslices. Sometimes, the additional hypothesis is added that the world lines form timelike geodesics.
The evolution of the dorsal pallium is not fully understood yet. Some authors hold that it largely contributes to the mammalian hippocampal allocortical and parahippocampal mesocortical (transitional) areas. Others postulate it directly transforms into the six-layered isocortex (neocortex) characteristic of mammals, and still others suppose that medial and lateral parts of the dorsal pallium contribute (perhaps with some contributions from the lateral pallium) to the alternative allocortical and isocortical fates.
Reconstruction of Ice Complex Remnants on the Eastern Siberian Arctic Shelf. Permafrost and Periglacial Processes. vol. 14, pp. 187–198. judging from other successes of Sannikov and the presence of shallow sand shoals at Sannikov Land's mapped location, postulate that it indeed once existed, but was destroyed by coastal erosion and became a submerged sand shoal, like many other islands formed either of fossilized ice or of permafrost.
Anemospilia was first excavated in 1979 by the Greek archaeologist Yannis Sakellarakis. The temple was destroyed by earthquake and fire around 1700 BC, about the same time as the destruction of the first palaces. The temple was found in a ruined state with stone walls only reaching hip height. Traces of ash and charcoal were found on the ground, and from this, one can postulate that the building was burnt down.
Prisoners requested the presence of Minister Louis Farrakhan, National Representative of the Nation of Islam, but he declined. The situation may have been further complicated by Governor Rockefeller's refusal to come to the scene of the uprising and meet with the inmates, although some later evaluations of the incident would postulate that his absence from the scene actually prevented the situation from deteriorating.Benjamin, G., & Rappaport, S. (1974). Attica and Prison Reform.
Several preon models have been proposed to address the unsolved problem concerning the fact that there are three generations of quarks and leptons. Preon models generally postulate some additional new particles which are further postulated to be able to combine to form the quarks and leptons of the standard model. One of the earliest preon models was the Rishon model. To date, no preon model is widely accepted or fully verified.
Young are fed by both parents, which spend the day at sea and return to the nest at night. Little is known of the life and times of the white-bellied storm petrel, but extrapolations from cogeners postulate a generation time of 15.2 years (assuming “an average age at first breeding of 4.7 years, an annual survival of adults of 87.8% and a maximum longevity of 30.4 years ”).
The Guardian. Retrieved December 26, 2014. Academic contributors to The Routledge Handbook of Poverty in the United States postulate that new and extreme forms of poverty have emerged in the U.S. as a result of neoliberal structural adjustment policies and globalization, which have rendered economically marginalized communities as destitute "surplus populations" in need of control and punishment. Many international bodies have emphasized the issues of poverty that the United States faces.
In neuroethology and the study of learning, anti-Hebbian learning describes a particular class of learning rule by which synaptic plasticity can be controlled. These rules are based on a reversal of Hebb's postulate, and therefore can be simplistically understood as dictating reduction of the strength of synaptic connectivity between neurons following a scenario in which a neuron directly contributes to production of an action potential in another neuron.
King Weneg-Nebty might be identical with the Ramesside cartouche name Wadjenes. But kings such as "Nubnefer", "Bird" and "Za" remain a mystery. They never appear anywhere else and the number of objects surviving from their lifetimes is very limited. Schlögl, Helck and Peter Kaplony postulate, that Nubnefer, Za and Bird were contemporaries of Peribsen and Sekhemib and ruled over Lower Egypt, whilst the latter two ruled Upper Egypt.
The concept of metacommunication has also been related to Communication Theory. Mateus (2017), influenced by Derrida's Graphematic Structure of Communication, suggested to see metacommunication as a self-differentiating redundancy. The concept here "describes communication as an ad infinitum process in which every communication supposes always more communication. Metacommunication is the answer to the relationship level of communication and that’s why we postulate metacommunication as a re-communicating communication" (Mateus, 2017).
In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times. The first extant sources discussing such theories are found in ancient Greek philosophy. This work was furthered by ancient Indian and medieval Islamic physicists, before gaining great strides during the Renaissance and Scientific Revolution, culminating in the formulation of Newton's law of gravity.
An axiom P is independent if there are no other axioms Q such that Q implies P. In many cases independence is desired, either to reach the conclusion of a reduced set of axioms, or to be able to replace an independent axiom to create a more concise system (for example, the parallel postulate is independent of other axioms of Euclidean geometry, and provides interesting results when a negated or replaced).
Hebbian theory is a neuroscientific theory claiming that an increase in synaptic efficacy arises from a presynaptic cell's repeated and persistent stimulation of a postsynaptic cell. It is an attempt to explain synaptic plasticity, the adaptation of brain neurons during the learning process. It was introduced by Donald Hebb in his 1949 book The Organization of Behavior. The theory is also called Hebb's rule, Hebb's postulate, and cell assembly theory.
The narrator recounts his history with the title character, who has recently disappeared. As a medical student at Miskatonic University, the narrator becomes fascinated by West's theories, which postulate that the human body is simply a complex, organic machine which can be "restarted." West eventually realizes he must experiment on human subjects. The two men spirit away supplies from their medical school and set up their lab in an abandoned farmhouse.
Zeta Cancri can be resolved as a binary star in small telescopes. Its binary nature was discovered in 1756 by Tobias Mayer. William Herschel resolved the two components that make up Zeta¹ Cancri in 1781. As early as 1831, John Herschel noticed perturbations in Zeta² Cancri's orbit around Zeta¹; this led Otto Wilhelm von Struve, in 1871, to postulate a fourth, unseen, component which orbited closely the visible member of Zeta².
He became known for detailed work on mycoparasitic fungi and the smut fungi in particular. He was able to use ultrastructural evidence to postulate phylogenies in this group before molecular techniques were developed. Subsequent molecular studies aligned with his hypotheses. Bauer produced over 100 publications during his career, during which time he was also strongly involved in teaching, the university's botanic garden and overseeing specialist internships in electronmicroscopy.
They additionally postulate that 16-year- olds will have their voice listened to by older people more often. Chilean director, Sebastian Lelio, created a U.S. version of his acclaimed 2013 film Gloria. The original film challenges the notion that as women age they become culturally 'invisible'; they may continue to be powerful, desirable, and sexually active. In the 2018 English remake, titled Gloria Bell, actress Julianne Moore portrayed the lead character.
Retrieved 2014-06-03. Fenwick and Parnia have claimed that research from NDEs may show the "mind is still there after the brain is dead". The neurologist Michael O'Brien has written "most people would not find it necessary to postulate such a separation between mind and brain to explain the events," and suggested that further research is likely to provide a physical explanation for near-death experiences.Michael O'Brien. (2003).
Their function is to act as a neutral arbitrator to resolve identity conflicts. The sublayer of democratic identity has to be specific, coherent with the principles of human equality and personal autonomy. Democratic identity is a regulative and arbitral postulate for a multicultural coexistence amongst identities that may be exclusionary. It has to be founded in reciprocal respect, derived from the recognition of each person's moral and political autonomy.
Wormholes are conjectural distortions in spacetime that theorists postulate could connect two arbitrary points in the universe, across an Einstein–Rosen Bridge. It is not known whether wormholes are possible in practice. Although there are solutions to the Einstein equation of general relativity that allow for wormholes, all of the currently known solutions involve some assumption, for example the existence of negative mass, which may be unphysical. However, Cramer et al.
After many failed attempts to derive the parallel postulate from other axioms, the study of the still hypothetical hyperbolic geometry by Johann Heinrich Lambert (1728–1777) led him to introduce the hyperbolic functions and compute the area of a hyperbolic triangle (where the sum of angles is less than 180°). Then the Russian mathematician Nikolai Lobachevsky (1792–1856) established in 1826 (and published in 1829) the coherence of this geometry (thus the independence of the parallel postulate), in parallel with the Hungarian mathematician János Bolyai (1802–1860) in 1832, and with Gauss. Later in the 19th century, the German mathematician Bernhard Riemann developed Elliptic geometry, another non-Euclidean geometry where no parallel can be found and the sum of angles in a triangle is more than 180°. It was proved consistent by defining point to mean a pair of antipodal points on a fixed sphere and line to mean a great circle on the sphere.
Euclidean geometry, named after the Greek mathematician Euclid, includes some of the oldest known mathematics, and geometries that deviated from this were not widely accepted as legitimate until the 19th century. The debate that eventually led to the discovery of the non-Euclidean geometries began almost as soon as Euclid wrote Elements. In the Elements, Euclid begins with a limited number of assumptions (23 definitions, five common notions, and five postulates) and seeks to prove all the other results (propositions) in the work. The most notorious of the postulates is often referred to as "Euclid's Fifth Postulate," or simply the parallel postulate, which in Euclid's original formulation is: > If a straight line falls on two straight lines in such a manner that the > interior angles on the same side are together less than two right angles, > then the straight lines, if produced indefinitely, meet on that side on > which are the angles less than the two right angles.
Researchers postulate that embedded carbon atoms with unpaired electrons carry enough of a magnetic moment to lead to strong magnetization. The sheet curvature localizes unpaired electrons by breaking up the π-electron clouds and sterically protects the electrons which normally would be too reactive to persist. The ferromagnetism of the carbon nanofoam is sensitive to time and temperature. Some magnetism is lost within the first few hours of synthesis, however most of it is persistent.
Bailey is known almost exclusively by his one voluminous poem, Festus, first published anonymously in 1839, and then expanded with a second edition in 1845. A vast pageant of theology and philosophy, it comprised in some twelve divisions an attempt to represent the relation of God to man, and to postulate "a gospel of faith and reason combined." Among the admirers of Festus was Tennyson. Henry Wadsworth Longfellow imitated it in The Golden Legend (1851).
An event is something that happens at a certain point in spacetime, or more generally, the point in spacetime itself. In any inertial frame an event is specified by a time coordinate ct and a set of Cartesian coordinates to specify position in space in that frame. Subscripts label individual events. From Einstein's second postulate of relativity (invariance of c) it follows that: in all inertial frames for events connected by light signals.
Chlorination favors the products because it is an exothermic reaction, which means that the products are lower in energy than the reactants. When looking at the adjacent diagram (representation of an "early" transition state), one must focus on the transition state, which is not able to be observed during an experiment. To understand what is meant by an “early” transition state, the Hammond postulate represents a curve that shows the kinetics of this reaction.
He made no mention of thermodynamics in this paper, though he did refer to conservation of vis viva. He proposed that his measurements implied that radiation was both absorbed and emitted by particles of matter throughout depths of the media in which it propagated. He applied the Helmholtz reciprocity principle to account for the material interface processes as distinct from the processes in the interior material. He did not postulate unrealizable perfectly black surfaces.
An illustration of Euclid's parallel postulate Euclid took an abstract approach to geometry in his Elements, one of the most influential books ever written. Euclid introduced certain axioms, or postulates, expressing primary or self-evident properties of points, lines, and planes. He proceeded to rigorously deduce other properties by mathematical reasoning. The characteristic feature of Euclid's approach to geometry was its rigor, and it has come to be known as axiomatic or synthetic geometry.
Absolute geometry is a geometry based on an axiom system consisting of all the axioms giving Euclidean geometry except for the parallel postulate or any of its alternatives.Use a complete set of axioms for Euclidean geometry such as Hilbert's axioms or another modern equivalent . Euclid's original set of axioms is ambiguous and not complete, it does not form a basis for Euclidean geometry. The term was introduced by János Bolyai in 1832.
In Euclid's Elements, the first 28 propositions and Proposition I.31 avoid using the parallel postulate, and therefore are valid theorems in absolute geometry. Proposition I.31 proves the existence of parallel lines (by construction). Also, the Saccheri–Legendre theorem, which states that the sum of the angles in a triangle is at most 180°, can be proved. The theorems of absolute geometry hold in hyperbolic geometry as well as in Euclidean geometry.
This model created by John Bancroft and Erick Janssen, previously at the Kinsey Institute, explores the individual variability of sexual response. They postulate that this variability depends on the interaction between an individual's sexual excitation system (SES) and sexual inhibition system (SIS). Popularized by Emily Nagoski's self-help book Come as You Are, the SES has been described as the sexual response's 'accelerator' and the SIS as the 'brake'.Nagoski, E. (2015).

The communication square describes the multi- layered structure of human utterances. It combines the idea of a postulate (second axiom) from Paul Watzlawick, that every message contains content and relational facets, with the three sides of the Organon model by Karl Bühler, that every message might reveal something about the sender, the receiver, and the request at hand. Such models are familiar in the linguistic community as part of speech act theory.
C. nasicornis had larger teeth than Allosaurus, and some paleontologists postulate that it would have had a difficult time attacking larger prey. Abelisaurids, however, carried many of these defining traits to their extremes. Most abelisaurids had largely shortened forelimbs, with Carnotaurus having shrunk them further than any large theropod. After analyzing the features of the newly discovered Rugops primus, Paul Sereno has postulated that many of these abelisaurid features may lend themselves to scavenging.
According to the esoteric religious movement Theosophy, whose claims were modified by Edgar Cayce, God created androgynous souls—equally male and female. Later theories postulate that the souls split into separate genders, perhaps because they incurred karma while playing around on the Earth, or "separation from God." Over a number of reincarnations, each half seeks the other. When all karmic debt is purged, the two will fuse back together and return to the ultimate.
Inasmuch as the authorship of Prometheus Bound continues to be debated, the very existence of a Prometheus trilogy is uncertain. To the extent that modern scholars postulate the existence of such a trilogy by a single author, the consensus holds that it comprised Prometheus Bound, Prometheus Unbound, and Prometheus the Fire-Bringer, in that order.For an introduction to the issues surrounding the trilogy's reconstruction, see (e.g.) D.J. Conacher, Aeschylus' Prometheus Bound: a Literary Commentary.
Extremal combinatorics owes to him a whole approach, derived in part from the tradition of analytic number theory. Erdős found a proof for Bertrand's postulate which proved to be far neater than Chebyshev's original one. He also discovered the first elementary proof for the prime number theorem, along with Atle Selberg. However, the circumstances leading up to the proofs, as well as publication disagreements, led to a bitter dispute between Erdős and Selberg.
The Academia Catarinense de Letras is composed by forty writers either born in Santa Catarina or that made history in the State. The chairs are lifetime positions, that is, new members can only be chosen after the death of a current member. When a chair is vacant, the Academy organizes an election between the remaining members to choose the new member. Any writer can postulate the chair, as long as they have a published book.
It brings to mind the famous fifth postulate of Euclid concerning parallels, which is more extensive and complicated in its wording than the other postulates. The Eudoxian definition of proportionality uses the quantifier, "for every ..." to harness the infinite and the infinitesimal, just as do the modern epsilon-delta definitions of limit and continuity. Additionally, the Archimedean property stated as definition 4 of Euclid's book V is originally due not to Archimedes but to Eudoxus.
Considering the notion that positrons were electrons that were traveling backwards in time, he came up in 1940 with his one-electron universe postulate: that there was in fact only one electron, bouncing back and forth in time. Richard Feynman, his graduate student, found this hard to believe, but the idea that positrons were electrons traveling backwards in time intrigued him and Feynman incorporated the notion of the reversibility of time into his Feynman diagrams.
Sporadic reports of unusual cases of peptic ulceration in the presence of pancreatic tumors occurred prior to 1955, but R. M. Zollinger and E. H. Ellison, surgeons at The Ohio State University, were the first to postulate a causal relationship between these findings. The American Surgical Association meeting in Philadelphia in April 1955 heard the first public description of the syndrome, and Zollinger and Ellison subsequently published their findings in Annals of Surgery.
Non-logical axioms are formulas that play the role of theory-specific assumptions. Reasoning about two different structures, for example the natural numbers and the integers, may involve the same logical axioms; the non-logical axioms aim to capture what is special about a particular structure (or set of structures, such as groups). Thus non-logical axioms, unlike logical axioms, are not tautologies. Another name for a non- logical axiom is postulate.
However, two lines in three-dimensional space which do not meet must be in a common plane to be considered parallel; otherwise they are called skew lines. Parallel planes are planes in the same three-dimensional space that never meet. Parallel lines are the subject of Euclid's parallel postulate.Although this postulate only refers to when lines meet, it is needed to prove the uniqueness of parallel lines in the sense of Playfair's axiom.
Arthāpatti (अर्थापत्ति), postulation, derivation from circumstances. In contemporary logic, this pramana is similar to circumstantial implication.Arthapatti Encyclopædia Britannica (2012) As example, if a person left in a boat on river earlier, and the time is now past the expected time of arrival, then the circumstances support the truth postulate that the person has arrived. Many Indian scholars considered this Pramana as invalid or at best weak, because the boat may have gotten delayed or diverted.
When the teams postulate that Stark has cancer, Wilson is brought in for a consultation. Stark's dismissal of an additional few months to live leads House to deride his philosophical beliefs. Wilson confronts House, saying that he doesn't know any better than anyone whether there is an afterlife. House later uses the knife he took from the clinic patient to electrocute himself (after paging Amber seconds before to come and resuscitate him).
However, according to Pauli and Miller such models were insufficient to identify the invariant speed in their transformation with the speed of light — for example, Ignatowski was forced to seek recourse in electrodynamics to include the speed of light. So Pauli and others argued that both postulates are needed to derive the Lorentz transformation.Pauli (1921), 555–556Miller (1981), 218–219 However, until today, others continued the attempts to derive special relativity without the light postulate.
As a result, all were thus subject to the effects of the extinction theorem. This implied that the light being measured would have had a velocity different from that of the original source. He concluded that there was likely as yet no acceptable proof of the second postulate of special relativity. This surprising gap in the experimental record was quickly closed in the ensuing years, by experiments by Fox, and by Alvager et al.
St. Peregrine is said to have founded Auxerre's cathedral, Saint-Etienne. Historians postulate that he was probably not a bishop at all, but rather a missionary who had been sent to the rural areas of this region. In the ninth century, churchmen of Auxerre made this local martyr the first bishop of their city. In the 7th century, some of his relics were translated from Bouhy to the Abbey of Saint-Denis.
McCarthy analyzes a dream of August Kekulé's as a model of the unconscious mind and the origins of language. He theorizes about the nature of the unconscious mind and its separation from human language. The unconscious, according to McCarthy, "is a machine for operating an animal" and that "all animals have an unconscious." McCarthy goes on to postulate that language is purely a human cultural creation, and not a biologically determined phenomenon.
The activity was likely from the 1649 stream. On December 8, 2013, Meteor specialist Peter Brown reported that the Canadian Meteor Orbit Radar had recorded an outburst from the Andromedid meteors in the past 24 hours. Scientists postulate a somewhat weaker return in 2018, but a yield of up to 200 meteors an hour in 2023. Canadian Meteor Orbit Radar (CMOR) data also detected a spike of 30 meteors per hour on November 27, 2008.
Some embryologists postulate that the ostium secundum may be formed through programmed cell death. The ostium secundum provides communication between the atria after the ostium primum closes completely. Subsequently, a second wall of tissue, the septum secundum, grows over the ostium secundum in the right atrium. Blood then only passes from the right to left atrium by way of a small passageway in the septum secundum and then through the ostium secundum.
Fred Cohen experimented with computer viruses and confirmed Neumann's postulate and investigated other properties of malware such as detectability and self-obfuscation using rudimentary encryption. His 1988 Doctoral dissertation was on the subject of computer viruses.Fred Cohen, "Computer Viruses", PhD Thesis, University of Southern California, ASP Press, 1988. Cohen's faculty advisor, Leonard Adleman, presented a rigorous proof that, in the general case, algorithmic determination of the presence of a virus is undecidable.
It is the first bipolar PPN known to have point reflection symmetry (all others being axially symmetric). Point symmetry is a fairly common trait of planetary nebulae as found in NGC 2022, NGC 2371-2, NGC 6309, Cat's Eye Nebula, NGC 6563, Dumbbell Nebula, Saturn Nebula, A24, and Hb5. postulate that point symmetry is either due to the bipolar outflow being directed by a precessing disc or a precessing common envelope binary.
Saunders showed that the Khazzoom–Brookes postulate occurs in the neoclassical growth model under a wide range of assumptions. According to Saunders, increased energy efficiency tends to increase energy consumption by two means. First, increased energy efficiency makes the use of energy relatively cheaper, thus encouraging increased use (the direct rebound effect). Second, increased energy efficiency increases real incomes and leads to increased economic growth, which pulls up energy use for the whole economy.
43), Paul VI criticizes the modern practices of exploiting nature. Each property, including the gifts of nature, stands under the principle of the common use (usus communis), from which no human being must be excluded, the encyclical says. Unlike Leo XIII’s encyclical Rerum novarum, Paul VI extends this postulate also on the natural environment and stresses the responsibility for future generations (no. 47). Thereby, Octogesima adveniens anticipates central motifs of the sustainability principle.
Boussinesq equations) in that the flow need not be irrotational, and that no perturbation is used in deriving the equations. Hence, the GN equations satisfy the nonlinear boundary conditions exactly, and postulate the integrated conservation laws. Although the GN equations were developed very recently (compared to other wave theories), they are well-known and fairly understood by the research and scientific community. Ertekin's Ph.D. advisor and dissertation committee chair was Professor Wehausen.
Minister of Labor Rafalska suggested an agreement which included the rise of the social allowance to the requested amount but did not cover the second postulate about the requested PLN500. Instead of that, the Ministry offered priority lines to some doctors and pharmacies. The protesters rejected the proposal, as they said that their two demands are inextricable. Finally, the government, without the participation of protesters, made an agreement with a group of organizations working for people with disabilities.
Egan uses his hypothetical future to postulate the existence of not just one but five new genders, and introduces a set of new pronouns for gender neutral people. One of the central characters of the novel, Akili Kuwale, provides a demonstration of this change and its implications. As an asexual human, Akili has had all reproductive organs removed entirely. Within the scope of the novel, Egan uses the pronouns 've', 'ver', and 'vis' to represent Akili's definitive gender neutrality.
Traditional Keresan beliefs postulate that Keres is a sacred language that must exist only in its spoken form. The language's religious connotation and years of persecution of Pueblo religion by European colonizers may also explain why no unified orthographic convention exists for Keresan. However, a practical spelling system has been developed for Laguna (Kʼawaika) and more recently for Acoma (Áakʼu) Keres, both of which are remarkably consistent. In the Keres spelling system, each symbol represents a single phoneme.
Hammond's postulate is especially important when looking at the rate-limiting step of a reaction. However, one must be cautious when examining a multistep reaction or one with the possibility of rearrangements during an intermediate stage. In some cases, the final products appear in skewed ratios in favor of a more unstable product (called the kinetic product) rather than the more stable product (the thermodynamic product). In this case one must examine the rate-limiting step and the intermediates.
For example, in an exothermic reaction the transition state is closer in energy to the reactants than to the products. Therefore, the transition state will be more geometrically similar to the reactants than to the products. In contrast, however, in an endothermic reaction the transition state is closer in energy to the products than to the reactants. So, according to Hammond’s postulate the structure of the transition state would resemble the products more than the reactants.
Since the reactants are higher in energy, the transition state appears to be right after the reaction starts. An example of the “late” transition state is bromination. Bromination favors the reactants because it is an endothermic reaction, which means that the reactants are lower in energy than the products. Since the transition state is hard to observe, the postulate of bromination helps to picture the “late” transition state (see the representation of the "late" transition state).
Addressing the majority's "suicide pact" idea, Black asserted that the First Amendment's tolerance of anti-democratic ideas was what protected the nation from disaster: "...the postulate of the First Amendment is that our free institutions can be maintained without proscribing or penalizing political belief, speech, press, assembly, or party affiliation. This is a far bolder philosophy than despotic rulers can afford to follow. It is the heart of the system on which our freedom depends."American Communications Association v.
These primary sources also postulate that Joseph H. Davis was probably born on August 10, 1811, in Limington, Maine to land trader Joseph Davis and his wife, Phebe. In addition to farming and land speculating, he also worked as a manufacturer and an inventor. He lived in several towns in the Northeast, including Saco, Vassalboro, and Newfield, Maine; Morristown, New Jersey; and Wilmington, Massachusetts. He died on May 25, 1865, at the age of fifty-three, in Woburn, Massachusetts.
Scott E. Page (2008), "agent-based models", The New Palgrave Dictionary of Economics, 2nd Edition. Abstract. The rules are formulated to predict behavior and social interactions based on incentives and information. The theoretical assumption of mathematical optimization by agents markets is replaced by the less restrictive postulate of agents with bounded rationality adapting to market forces.• Holland, John H., and John H. Miller (1991). "Artificial Adaptive Agents in Economic Theory", American Economic Review, 81(2), pp.
The traditional debate has focused on whether an abstract (immaterial, intelligible) realm of numbers has existed in addition to the physical (sensible, concrete) world. A recent development is the mathematical universe hypothesis, the theory that only a mathematical world exists, with the finite, physical world being an illusion within it. An extreme form of realism about mathematics is the mathematical multiverse hypothesis advanced by Max Tegmark. Tegmark's sole postulate is: All structures that exist mathematically also exist physically.
It goes on to the solid geometry of three dimensions. Much of the Elements states results of what are now called algebra and number theory, explained in geometrical language. For over two thousand years, the adjective "Euclidean" was unnecessary because no other sort of geometry had been conceived. Euclid's axioms seemed so intuitively obvious (with the possible exception of the parallel postulate) that any theorem proved from them was deemed true in an absolute, often metaphysical, sense.
In 1983 General Óscar Humberto Mejía took power in another coup, which Cerezo cautiously supported. The DCG gained 21.2% of the vote in the 1984 National Congress elections, and with 20 of the 88 seats was the largest party. With this success behind them the DCG decided to postulate Cerezo for the 1985 presidential election. He began to promote the idea of talking to the United Guatemalan National Revolutionaries (URNG), an umbrella group containing the main three guerrilla groups.
For macroeconomics, relevant partial theories included the Quantity theory of money determining the price level and the classical theory of the interest rate. In regards to employment, the condition referred to by Keynes as the "first postulate of classical economics" stated that the wage is equal to the marginal product, which is a direct application of the marginalist principles developed during the nineteenth century (see The General Theory). Keynes sought to supplant all three aspects of the classical theory.

Also, if the president and/or vice president is running for office, he may participate in their political party's selection mechanism to postulate candidates. In 2010, the Constitutional Court of Colombia threw out a planned referendum to allow presidents to run for three consecutive terms. It ruled that Colombian presidents can only serve two terms, even if they are nonconsecutive. In 2015, a constitutional amendment repealed the 2004 changes and reverted to the original one-term limit.
Most Muslim countries have mixed legal systems that postulate a constitution and Rule of Law, while also allowing rules of traditional Islamic jurisprudence to influence certain areas of national law. These systems possess large bodies of codified laws, which may be based on European or Indian codes. In these systems, the central legislative role is played by politicians and modern jurists rather than traditional religious scholars. Pakistan, Egypt, Malaysia, and Nigeria are examples of states having mixed systems.

It has also been suggested that ethane emissions measured in Europe are affected by hydraulic fracturing and shale gas production operations in North America. Some researchers postulate that leakage problems are more likely to happen in unconventional wells, which are hydraulically fractured, than in conventional wells. Approximately 40% of methane emissions in Canada occur within Alberta, according to the National Inventory Report. Of the anthropogenic methane emissions in Alberta, 71% are generated by the oil and gas sector.
Research on depression indicates that one of the major causal factors of depression, stress, also influences neurogenesis. This connection led researches to postulate that depression could be the result of changes in levels of neurogenesis in the adult brain, specifically in the dentate gyrus. Studies indicate that stress affects neurogenesis by increasing Glucocorticoids and decreasing neurotransmitters such as serotonin. These effects were further verified by inducing stress in lab animals, which resulted in decreased levels of neurogenesis.
Assume the second postulate of special relativity stating the constancy of the speed of light, independent of reference frame, and consider a collection of reference systems moving with respect to each other with constant velocity, i.e. inertial systems, each endowed with its own set of Cartesian coordinates labeling the points, i.e. events of spacetime. To express the invariance of the speed of light in mathematical form, fix two events in spacetime, to be recorded in each reference frame.
If a message was not received correctly Redding refers to that as content fallacy. With the concept of content fallacy the sender believes that they are getting through to the receiver just because they, the sender, understand the message that is being sent. # Anything is a potential message: This postulate includes both verbal and non verbal cues and messages being received as a message. # Input (specifically listening): In his novel, Redding discusses how to be a good listener.
NMDA receptors can detect local activity due to activation and therefore modify signaling in the post-synaptic cell. The increased activity and coordination between pre- and post-synaptic receptors leads to more permanent changes and therefore result in plasticity. Hebb's postulate addresses this fact by stating that synaptic terminals are strengthened by correlated activity and will therefore sprout new branches. However, terminals that experience weakened and minimal activity will eventually lose their synaptic connection and deteriorate.
Arthāpatti (अर्थापत्ति) means postulation, derivation from circumstances. In contemporary logic, this pramana is similar to circumstantial implication.Arthapatti Encyclopædia Britannica (2012) As example, if a person left in a boat on river earlier, and the time is now past the expected time of arrival, then the circumstances support the truth postulate that the person has arrived. Many Indian scholars considered this pramana as invalid or at best weak, because the boat may have gotten delayed or diverted.
According to postulate 7, the closer an object, the more visual rays fall upon it and the more detailed or sharp it appears. This is an early attempt to describe the phenomenon of optical resolution. Much of the work considers perspective, how an object appears in space relative to the eye. For example, in proposition 8, Euclid argues that the perceived size of an object is not related to its distance from the eye by a simple proportion.
Georg Simon Klügel Georg Simon Klügel (August 19, 1739 - August 4, 1812) was a German mathematician and physicist. He was born in Hamburg, and in 1760 went to the University of Göttingen where he initially studied theology before switching to mathematics. Georg Christoph Lichtenberg was a fellow student. His doctoral thesis Conatuum praecipuorum theoriam parallelarum demonstrandi recensio, published in 1763 with Abraham Gotthelf Kästner as doctoral advisor, was a study of 30 attempted proofs of the parallel postulate.
Scientists at the University of Pittsburgh, Carnegie Mellon University, and Duquesne University work in diverse fields of physics, chemistry, and engineering towards a wide range of applications. They investigate surfaces and heterojunctions, quantum dots and potential energy surfaces, non-linear optical systems and entangled qubits. They postulate, develop, fabricate, characterize, calculate. The Pittsburgh Quantum Institute was founded to bring together those key players of the quantum scene in a unified yet diverse community for the promotion of quantum research.
It is debated in research on visual spatial attention whether it is possible to split attention across different areas in the visual field. The ‘spotlight’ and ‘zoom-lens’ accounts postulate that attention uses a single unitary focus. Therefore, spatial attention can only be allocated to adjacent areas in the visual field and consequently cannot be split. This was supported by an experiment that altered the spatial cueing paradigm by using two cues, a primary and a secondary cue.
This choice gives us two alternative forms of geometry in which the interior angles of a triangle add up to exactly 180 degrees or less, respectively, and are known as Euclidean and hyperbolic geometries. If one also removes the second postulate ("a line can be extended indefinitely") then elliptic geometry arises, where there is no parallel through a point outside a line, and in which the interior angles of a triangle add up to more than 180 degrees.
According to Tyndale, church authorities adduce that a man must have a pure and quiet mind to read and fully comprehend scripture, and that the average man is too encumbered with worldly matters to do so. Tyndale counters this argument stating no one is as occupied with worldly matters as the church. Authorities also postulate that if every man were able to read scripture, every man would interpret it for himself, leading to widespread non-conformity and insurrection.
Prigogine, I., (1955/1967), p. 12. There is a sense in which this kind of additivity expresses a fundamental postulate that goes beyond the simplest ideas of classical closed system thermodynamics; the extensivity of some variables is not obvious, and needs explicit expression; indeed one author goes so far as to say that it could be recognized as a fourth law of thermodynamics, though this is not repeated by other authors.Landsberg, P. T. (1961), pp. 142, 387.

Leduc, 1910 He also noted this term in another publication, La Biologie Synthétique in 1912. 1961: Jacob and Monod postulate cellular regulation by molecular networks from their study of the lac operon in E. coli and envisioned the ability to assemble new systems from molecular components.Jacob, F.ß.
The definition of parallel lines as a pair of straight lines in a plane which do not meet appears as Definition 23 in Book I of Euclid's Elements. Alternative definitions were discussed by other Greeks, often as part of an attempt to prove the parallel postulate. Proclus attributes a definition of parallel lines as equidistant lines to Posidonius and quotes Geminus in a similar vein. Simplicius also mentions Posidonius' definition as well as its modification by the philosopher Aganis.
At that time, and so far up until today, the Cesium atoms employed in their experiment represent the largest quantum objects which have been used to experimentally test the Leggett–Garg inequality. The experiments of Robens et al. as well as Knee et al., using ideal negative measurements, also avoid a second criticism (referred to as “clumsiness loophole”) that has been directed to previous experiments using measurement protocols that could be interpreted as invasive, thereby conflicting with postulate 2.
These commentaries of Samkhya postulate that a benevolent deity ought to create only happy creatures, not a mixed world like the real world. A majority of modern academic scholars are of view that the concept of Ishvara was incorporated into the nirishvara (atheistic) Samkhya viewpoint only after it became associated with the Yoga, the Pasupata and the Bhagavata schools of philosophy. This theistic Samkhya philosophy is described in the Mahabharata, the Puranas and the Bhagavad Gita.
Arthāpatti (अर्थापत्ति) means postulation, derivation from circumstances. In contemporary logic, this pramāṇa is similar to circumstantial implication.Arthapatti Encyclopædia Britannica (2012) As example, if a person left in a boat on a river earlier, and the time is now past the expected time of arrival, then the circumstances support the truth postulate that the person has arrived. Many Indian scholars considered this pramāṇa as invalid or at best weak, because the boat may have gotten delayed or diverted.
" Ernest Kurtz says this is "The closest the book Alcoholics Anonymous comes to a definition of alcoholism." Somewhat divergently in his introduction to The Big Book, non-member and early benefactor William Silkworth said those unable to moderate their drinking suffer from an allergy. In presenting the doctor's postulate AA said "The doctor's theory that we have an allergy to alcohol interests us. As laymen, our opinion as to its soundness may, of course, mean little.
Cloud formations in a famous image of Earth from Apollo 17, makes similar circulation directly visible Perhaps the most important impact of the Coriolis effect is in the large-scale dynamics of the oceans and the atmosphere. In meteorology and oceanography, it is convenient to postulate a rotating frame of reference wherein the Earth is stationary. In accommodation of that provisional postulation, the centrifugal and Coriolis forces are introduced. Their relative importance is determined by the applicable Rossby numbers.
The earliest Greek philosophers, known as the pre-Socratics, provided competing answers to the question found in the myths of their neighbours: "How did the ordered cosmos in which we live come to be?"F. M. Cornford, Principium Sapientiae: The Origins of Greek Philosophical Thought, (Gloucester, Mass., Peter Smith, 1971), p. 159. The pre-Socratic philosopher Thales, dubbed the "father of science", was the first to postulate non- supernatural explanations for natural phenomena such as lightning and earthquakes.
Emotivists think not, claiming that we do not need to postulate the existence of moral "badness" or "wrongness" to explain why considering certain deeds makes us feel disapproval; that all we really observe when we introspect are feelings of disapproval. Thus the emotivist asks why not adopt the simple explanation and say that this is all there is, rather than insist that some intrinsic "badness" (of murder, for example) must be causing feelings when a simpler explanation is available.
The SN1 mechanism tends to dominate when the central carbon atom is surrounded by bulky groups because such groups sterically hinder the SN2 reaction. Additionally, bulky substituents on the central carbon increase the rate of carbocation formation because of the relief of steric strain that occurs. The resultant carbocation is also stabilized by both inductive stabilization and hyperconjugation from attached alkyl groups. The Hammond–Leffler postulate suggests that this too will increase the rate of carbocation formation.
There have been suggestions that interpersonal trauma such as betrayal trauma can in some cases have links to substance use. This substance use may be episodic binge drinking or chronic substance use that can meet diagnostic criteria for substance use disorder. Research found that childhood physical or sexual abuse is at increased risk for substance abuse. Some postulate that because betrayal trauma can create a loss of control that loss of control incorporates into substance use.
163 Many of the chapters in the Big Book were written by Wilson, including Chapter 8, To Wives. It was a chapter he had offered to Smith's wife, Anne Smith, to write, but she declined. His wife Lois had wanted to write the chapter, and his refusal to allow her left her angry and hurt. Some postulate the chapter appears to hold the wife responsible for her alcoholic husband's emotional stability once he has quit drinking.
Euclid's formulation of the parallel postulate may be stated in terms of a transversal. Specifically, if the interior angles on the same side of the transversal are less than two right angles then lines must intersect. In fact, Euclid uses the same phrase in Greek that is usually translated as "transversal".Heath p. 308 note 1 Euclid's Proposition 27 states that if a transversal intersects two lines so that alternate interior angles are congruent, then the lines are parallel.
He finally reached a point where he believed that his results demonstrated the impossibility of hyperbolic geometry. His claim seems to have been based on Euclidean presuppositions, because no logical contradiction was present. In this attempt to prove Euclidean geometry he instead unintentionally discovered a new viable geometry, but did not realize it. In 1766 Johann Lambert wrote, but did not publish, Theorie der Parallellinien in which he attempted, as Saccheri did, to prove the fifth postulate.
The inconsistency among his statements led Munro Edmonson (1971) to postulate that there had been multiple manuscripts in Guatemala. After Brasseur's death in 1874, the Mexico-Guatémalienne collection containing Popol Vuh passed to Alphonse Pinart, through whom it was sold to Edward E. Ayer. In 1897, Ayer decided to donate his 17,000 pieces to The Newberry Library in Chicago, a project that was not completed until 1911. Father Ximénez's transcription- translation of Popol Vuh was among Ayer's donated items.
During the following decades, a number of conditions could be linked to autoimmune responses. However, the authoritative status of Ehrlich's postulate hampered the understanding of these findings. Immunology became a biochemical rather than a clinical discipline.Arthur M. Silverstein: Autoimmunity: A History of the Early Struggle for Recognition, in: Ian R. Mackay, Noel R Rose: The Autoimmune Diseases (chapter 2), Academic Press, 2013 By the 1950s the modern understanding of autoantibodies and autoimmune diseases started to spread.
Some writers go further to postulate that the mature thylacine's jaw and bipedal hop were specialised for hunting the emu and either breaking its neck or severing the jugular vein. The emu was a large, flightless bird which shared the habitat of the thylacine and was hunted to extinction by humans around 1850, possibly coinciding with the decline in thylacine numbers.Paddle (2000), pp. 81. Both dingoes and foxes have been noted to hunt the emu on the mainland.
Bailyn, M. (1994). A Survey of Thermodynamics, American Institute of Physics Press, New York, , p. 22. In reality, practically nothing in nature is in strict thermodynamic equilibrium, but the postulate of thermodynamic equilibrium often provides very useful idealizations or approximations, both theoretically and experimentally; experiments can provide scenarios of practical thermodynamic equilibrium. In equilibrium thermodynamics the state variables do not include fluxes because in a state of thermodynamic equilibrium all fluxes have zero values by definition.
Kelsen's theory does postulate that a “legal order” (basic norm) underlies every legal system which in turn consists of legal norms (binding rules of conduct). A legal order (basic norm) determines legal norms, which are valid as long as they are in accordance with the legal order establishing them. Legal Norms under a legal system may include periodic elections by which power is successively transferred, for example. Abiding by legal norms begets legitimacy and defying them creates illegitimacy.
Galfredus, Galfred or Geoffrey de Liberatione was Bishop of Dunkeld and Bishop-postulate of St Andrews. He was a clerk to King Alexander II of Scotland as early as 1219, as well as being a canon of Dunkeld and precentor of Glasgow. He was elected to the bishopric of Dunkeld in 1236. After an investigation by Pope Gregory IX regarding a defect of birth possessed by Galfred, he was confirmed as bishop in sometime in 1237.
Complete skulls of this species are uncommon, but some fragmentary narrow- snouted phytosaur specimens from the Redonda Formation may be part of the taxon. R. bermani: Differs from other Redondasaurus species in that it has a rostrum with a partial crest. Only one skull of this species has been found, but Hunt and Lucas postulate that "by analogy with other phytosaurs, it is likely that this crested species was sub-equal in abundance with [R. gregorii].".
Dan Vogel, Joseph Smith: The Making of a Prophet (Salt Lake City: Signature Books, 2004). Smith Sr.'s dream was first recorded by his wife Lucy Mack Smith after publication of the Book of Mormon, and some Latter- day Saint scholars suggest that the text of the Book of Mormon may have influenced Lucy's account, rather than vice versa. Other apologetic scholars, such as Hugh Nibley, postulate that Lehi and Smith Sr. simply had the same archetypal vision.Nibley, Hugh.
In comparative cultural studies, ideally, the framework of and methodologies available in the systemic and empirical study of culture are favored. Scholarship in comparative cultural studies includes the theoretical, as well as methodological and applied postulate to move and to dialogue between cultures, languages, literature, and disciplines: attention to other cultures against essentialist notions and practices and beyond the paradigm of the nation-state is a basic and founding element of the framework and its application.
Verena Lepper and Miriam Lichtheim postulate that the tales of Papyrus Westcar inspired later authors to compose and write down similar tales. They refer to multiple, and somewhat later, ancient Egyptian writings in which magicians perform very similar magic tricks and make prophecies to a king. Descriptive examples are the papyri pAthen and The prophecy of Neferti. These novels show the popular theme of prophesying used during the Old Kingdom – just as in the story of the Westcar Papyrus.
Where the angle is a right angle, also known as the Hypotenuse-Leg (HL) postulate or the Right-angle-Hypotenuse-Side (RHS) condition, the third side can be calculated using the Pythagorean Theorem thus allowing the SSS postulate to be applied. If two triangles satisfy the SSA condition and the corresponding angles are acute and the length of the side opposite the angle is equal to the length of the adjacent side multiplied by the sine of the angle, then the two triangles are congruent. If two triangles satisfy the SSA condition and the corresponding angles are acute and the length of the side opposite the angle is greater than the length of the adjacent side multiplied by the sine of the angle (but less than the length of the adjacent side), then the two triangles cannot be shown to be congruent. This is the ambiguous case and two different triangles can be formed from the given information, but further information distinguishing them can lead to a proof of congruence.
Routledge, London/New York 1999, , p 98. Wolfgang Helck, Peter Kaplony and Jean-Pierre Pätznik instead read the name as djeseret-ankh-nebti (‘the noble one who lives for the two ladies’) and see it as the name of a wife of king Sekhemkhet. They point to several clay seals found at Elephantine, which show Sekhemkhet's horus name alternating with the nebty name Hetep-Ren and postulate that this could be the original birth name of Sekhemkhet.Wolfgang Helck: Untersuchungen zur Thinitenzeit.
The lack of cranial morphological differentiation between G. texensis and its sibling species have posed problems for scientists attempting to affirm the characteristics unambiguously associated with G. texensis. Conservation of morphological characters, that scientists postulate arose from adaptations to a fossorial lifestyle, is one reason G. texensis and its pocket gopher siblings look alike. Genetic isolation is rarely complemented by morphological evolution. This phenomenon leads to the need for a more comprehensive understanding of the genetic makeup of G. texensis and its siblings.
We can prove by several means either proof theoretic (algebraic steps); or semantic (truth table, method of analytic tableaux, Venn diagram, Veitch diagram / Karnaugh map) known in propositional calculus that :\left(A \land \left( A \rightarrow B\right)\right) \rightarrow B holds. Since i-j \mid m, by the transitivity property of the divisibility relation, p \mid i-j \rightarrow p \mid m. Thus (as equality axioms postulate identity to be a congruence relation ) :p \mid m can be proven.
In mathematics, Bertrand's postulate (actually a theorem) states that for each n\ge 2 there is a prime p such that n. It was first proven by Pafnuty Chebyshev, and a short but advanced proof was given by Srinivasa Ramanujan. The gist of the following elementary proof is due to Paul Erdős. The basic idea of the proof is to show that a certain central binomial coefficient needs to have a prime factor within the desired interval in order to be large enough.
Since the products are higher in energy, the transition state appears to be right before the reaction is complete. One other useful interpretation of the postulate often found in textbooks of organic chemistry is the following: :Assume that the transition states for reactions involving unstable intermediates can be closely approximated by the intermediates themselves. This interpretation ignores extremely exothermic and endothermic reactions which are relatively unusual and relates the transition state to the intermediates which are usually the most unstable.
Alternative responses modify the postulate of egoistic rationality in various ways. For example, Brennan and Lomasky suggest that voters derive 'expressive' benefits from supporting particular candidates. However, this implies that voting choices are unlikely to reflect the self- interest of voters, as is normally assumed in public choice theory; that is, rational behavior is restricted to the instrumental as opposed to the intrinsic value of actions. Some have hypothesized that voting is linked genetically with evolved behaviors such as cooperation.
Commentators who advocate Beaumont's authorial contribution must postulate a date of authorship prior to Beaumont's 1613 retirement and 1616 death, in the face of a lack of evidence. Conversely, Fletcher is supposed by some calculations to have worked on eleven plays in the last four years of his life; adding a twelfth stretches the credulity of some commentators.Baldwin Maxwell, Studies in Beaumont, Fletcher, and Massinger, Chapel Hill, NC, University of North Carolina Press, 1939; pp. 147-65, especially p. 148.
Its case is somewhat unusual in that the gauge field is a tensor, the Lanczos tensor. Theories of quantum gravity, beginning with gauge gravitation theory, also postulate the existence of a gauge boson known as the graviton. Gauge symmetries can be viewed as analogues of the principle of general covariance of general relativity in which the coordinate system can be chosen freely under arbitrary diffeomorphisms of spacetime. Both gauge invariance and diffeomorphism invariance reflect a redundancy in the description of the system.
However, other scientists did come to the conclusion that the aether did not exist. The results of the Michelson–Morley experiments supported Albert Einstein's strong postulate in 1905 that the speed of light is a constant in all inertial frames of reference for his Special Theory of Relativity. Morley also collaborated with Dayton Miller on positive aether experiments after his work with Michelson. Morley himself made measurements of the speed of light when it passes through a strong magnetic field.
Other images on his eclipse plates led him to postulate the existence of an asteroid belt between Mercury and the Sun. None of these claims has ever been substantiated after more than forty years of observation. It has been surmised that some of these objects—and other alleged intra-Mercurial objects—may exist, being nothing more than previously unknown comets or small asteroids. No vulcanoid asteroids have been found, and searches have ruled out any such asteroids larger than about .
The infinitude of prime numbers is proved. Books XI–XIII concern solid geometry. A typical result is the 1:3 ratio between the volume of a cone and a cylinder with the same height and base. The parallel postulate: If two lines intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.
The Born rule is essential to the Copenhagen interpretation,, p. 586: "In this connexion [Born] succeeded in obtaining a statistical interpretation of the wave functions, allowing a calculation of the probability of the individual transition processes required by the quantum postulate.". and Max Born speaks of his probability interpretation as a "statistical interpretation" of the wave function."... the statistical interpretation, which I have first suggested and which has been formulated in the most general way by von Neumann, ..." Born, M. (1953).
SPQL model. It is safe to postulate that all people want to have a good life. Although the meaning of “a good life” may vary from culture to culture and from individual to individual, this meaning revolves around the same aspects of life across cultures. What actually varies between cultures and individuals is the availability of certain aspects of a good life, the subjective significance people assign to these aspects, and the way people evaluate these aspects of a good life.
His academic career began in 1948 with a teaching position at Iowa State College; he served as Assistant Professor of Chemistry. In his capacity there he published Hammon's postulate which has widely known as the most important publication in the field of organic photochemistry. He moved to the University of Oxford and University of Basel as a Guggenheim Fellow and National Science Foundation Fellow, respectively. In 1958, he moved to the California Institute of Technology as a Professor of Organic Chemistry.

Sarah A. Solovay and John M. Mueller, ed. George E. G. Catlin (1938, 1964 edition), pp. 45 Durkheim endeavoured to apply sociological findings in the pursuit of political reform and social solidarity. Today, scholarly accounts of Durkheim's positivism may be vulnerable to exaggeration and oversimplification: Comte was the only major sociological thinker to postulate that the social realm may be subject to scientific analysis in the same way as noble science, whereas Durkheim acknowledged in greater detail the fundamental epistemological limitations.
She co-funded with Jacques Rancière the journal Les Révoltes logiques ( "Logical revolts"). Author of around 20 books, her work focuses on the political epistemology of feminist thought. Her research led her to postulate concepts on the "domestic service", "exclusive democracy," "women's reason", the "two governments", the "mixing of the sexes", "habeas corpus" and "consent". The complexity of the debate on gender led her to work closely with the historians, particularly on the synthesis of the history of women in the West.
Advaita took over from the Madhyamika the idea of levels of reality. Usually two levels are being mentioned, namely saṃvṛti-satya, "the empirical truth",Encyclopædia Britannica, saṃvṛti-satya and paramārtha-satya, "ultimate truth". According to Plott, The distinction between the two truths (satyadvayavibhāga) was fully expressed by the Madhyamaka-school. In Nāgārjuna's Mūlamadhyamakakārikā it is used to defend the identification of dependent origination (pratītyasamutpāda) with emptiness (śūnyatā): Shankara uses sublation as the criterion to postulate an ontological hierarchy of three levels:advaita-vision.
He utilizes the example of a participative manager listening to his subordinates in an empathetic manner. # The message that is received is the one that will bring action: The message that is sent and received is the one that will be acted up on. Redding states that the receiver will reference their personal experiences as a point of reference to act up on the message received. # Feedback (Responsiveness and Receptiveness): This postulate deals with feedback within an organization from both managers and subordinates.
Gentile made a pivotal distinction to factors concerning Idealism's own criteria for reality, which have stood since Berkeley's adage "Esse est percipi" by distinguishing between "pensiero pensante" the 'act of thinking', and the 'static thought' "pensiero pensato". Gentile posited then, that knowledge as thought fixed against a fuller range of thinking limits thinking's every proposition. If truth is what surpasses the conditions of every proposition, taking a known postulate as truth removes its criteria from having that capability in thinking. Objectifying actuality.
A Chinese early text gives a similar description, stating that Aṅgulimāla's teacher followed the gruesome instructions of his guru, to attain immortality. Xuan Zang's suggestion was further developed by European translators of Xuan Zang's travel accounts in the early twentieth century, but partly based on translation errors. Regardless, Gombrich is the first recent scholar to postulate this idea. However, Gombrich's claim that tantric practices existed before the finalization of the canon of Buddhist discourses (two to three centuries BCE) goes against mainstream scholarship.
Purity has advocated for the empowerment of young women to reduce the cases of gender-based violence. Kagwiria interned at the Coalition On Violence Against Women, COVAW, where she worked with the then Executive Director Anne Gathumbi who helped her gain exposure on gender issues. At COVAW, she collected over 10,000 signatures to postulate the Government of Kenya to sign the Maputo Protocol which was ratified in 2010. Based on this experience, she was able to lay foundation for her activism.
Hoffmann and Gorczynski have reproduced the Takemori and Tada experiment, confirming the existence of specific T cell factors. In the symmetrical network theory tabs are able to block V regions and also to have a stimulatory role when bound to a tab receptor on A cells. Symmetrical stimulatory interactions follow from the postulate that activation of B cells, T cells and A cells involves cross-linking of receptors. The symmetrical network theory has been developed with the assistance of mathematical modeling.
Additionally, they discovered that precursor molecules contain one to two glucose molecules, which was a surprising find. Up until this point, all N-linked oligosaccharides that had been characterized lacked glucose molecules. This lead the group to postulate that the oligosaccharide component of the precursor was modified by glycosidase enzymes before the glycoprotein could be considered mature. This work was very important in laying the foundation for later research that described the mechanism for the complete assembly glycoproteins in the endoplasmic reticulum.
Already in October 1965 the magazine had published an article on the new radical theological movement. The April 8, 1966, cover of Time magazine was the first cover in the magazine's history to feature only type, and no photo. The coverwith the traditional, red borderwas all black, with the words "Is God Dead?" in large, red text. The question was a reference to Friedrich Nietzsche's much-quoted postulate "God is dead" (), which he first proposed in his 1882 book The Gay Science.
Any two-dimensional system is uniquely specified by two parameters. Choosing a different pair of parameters, such as pressure and volume instead of pressure and temperature, creates a different coordinate system in two-dimensional thermodynamic state space but is otherwise equivalent. Pressure and temperature can be used to find volume, pressure and volume can be used to find temperature, and temperature and volume can be used to find pressure. An analogous statement holds for higher-dimensional spaces, as described by the state postulate.
Her husband was John Kendall Cannizzo, an astrophysicist at NASA.John K. Cannizzo They have one daughter, a ballet dancer who studied maths at the University of Cambridge and UC Berkeley. Catherine Asaro is the daughter of Frank Asaro, the nuclear chemist who discovered the iridium anomaly that led the team of Luis Alvarez, Walter Alvarez, Frank Asaro, and Helen Michel to postulate that an asteroid collided with the Earth 66 million years ago and caused mass extinctions, including the demise of the dinosaurs.
Direct Seleucid control of Jerusalem was short lived, and around 168 BC the Hasmonean Revolt broke out. Although 2 Maccabees contains a reference to a citadel a few years before the revolt, there is not a single mention of a Hellenistic citadel north of the Temple enclosure during or after the revolt. Its sudden disappearance have led some to postulate that the Ptolemaic Baris and Seleucid Acra were in fact one and the same.Bar-Kochva. 1989. Judas Maccabeus, pp. 445–465.
Quantum mechanics has two fundamentally different dynamical principles: the linear and deterministic Schrödinger equation, and the nonlinear and stochastic wave packet reduction postulate. The orthodox interpretation, or Copenhagen interpretation of quantum mechanics, posits a wave function collapse every time an observer performs measurement. One thus faces the problem of defining what an “observer” and a “measurement” are. Another issue of quantum mechanics is that it forecasts superpositions of macroscopic objects, which are not observed in Nature (see Schrödinger’s cat paradox).
Fred Cohen experimented with computer viruses and confirmed Neumann's postulate and investigated other properties of malware such as detectability and self-obfuscation using rudimentary encryption. His 1987 doctoral dissertation was on the subject of computer viruses.Fred Cohen, "Computer Viruses", PhD Thesis, University of Southern California, ASP Press, 1988. The combination of cryptographic technology as part of the payload of the virus, exploiting it for attack purposes was initialized and investigated from the mid 1990s, and includes initial ransomware and evasion ideas.
Elliptic geometry is an example of a geometry in which Euclid's parallel postulate does not hold. Instead, as in spherical geometry, there are no parallel lines since any two lines must intersect. However, unlike in spherical geometry, two lines are usually assumed to intersect at a single point (rather than two). Because of this, the elliptic geometry described in this article is sometimes referred to as single elliptic geometry whereas spherical geometry is sometimes referred to as double elliptic geometry.
It can be predicted using quantum mechanics, absent a collapse postulate, that an observer observing a quantum superposition will turn into a superposition of different observers seeing different things. The observer will have a wavefunction which describes all the possible outcomes. Still, in actual experience, an observer never senses a superposition, but always senses that one of the outcomes has occurred with certainty. This apparent conflict between a wavefunction description and classical experience is called the problem of observation (see Measurement problem).
A lion-faced deity found on a Gnostic gem in Bernard de Montfaucon's L'antiquité expliquée et représentée en figures may be a depiction of the Demiurge. Gnostic and Gnostic-influenced religions postulate the idea that the material world is inherently evil. The One true God is remote, beyond the material universe, therefore this universe must be governed by an inferior imposter deity. This deity was identified with the deity of the Old Testament by some sects, such as the Sethians and the Marcions.
All experiments conducted to date have found behavior in line with the predictions of quantum mechanics. The present view of the situation is that quantum mechanics flatly contradicts Einstein's philosophical postulate that any acceptable physical theory must fulfill "local realism". The fact that quantum mechanics violates Bell inequalities indicates that any hidden- variable theory underlying quantum mechanics must be non-local; whether this should be taken to imply that quantum mechanics itself is non-local is a matter of debate.
The theory of classical or equilibrium thermodynamics is idealized. A main postulate or assumption, often not even explicitly stated, is the existence of systems in their own internal states of thermodynamic equilibrium. In general, a region of space containing a physical system at a given time, that may be found in nature, is not in thermodynamic equilibrium, read in the most stringent terms. In looser terms, nothing in the entire universe is or has ever been truly in exact thermodynamic equilibrium.
He is usually credited with the proof of the Pythagorean theorem using similar triangles. However, Thabit Ibn Qurra (AD 901), an Arab mathematician, had produced a generalisation of the Pythagorean theorem applicable to all triangles six centuries earlier. It is a reasonable conjecture that Wallis was aware of Thabit's work. Wallis was also inspired by the works of Islamic mathematician Sadr al-Tusi, the son of Nasir al-Din al- Tusi, particularly by al-Tusi's book written in 1298 on the parallel postulate.
Thelema roughly means "will" in Greek. The phrase True Will does not appear in The Book of the Law, the central sacred text of Thelema. Nevertheless, Aleister Crowley's various commentaries on the Book routinely postulate that each individual has a unique and incommensurable True Will that determines his or her proper course in life. Crowley's invention appears to be an attempt to explain how some actions may be wrong (or "false") when "There is no law beyond Do what thou wilt".
Given the fact that Chant was learned in an oral tradition in which the texts and melodies were sung from memory, this was obviously not necessary. The neumatic manuscripts display great sophistication and precision in notation and a wealth of graphic signs to indicate the musical gesture and proper pronunciation of the text. Scholars postulate that this practice may have been derived from cheironomic hand-gestures, the ekphonetic notation of Byzantine chant, punctuation marks, or diacritical accents.Levy, Kenneth: "Plainchant", Grove Music Online, ed.
To > describe a circle with any centre and distance [radius]. 4\. That all right > angles are equal to one another. For at least a thousand years, geometers were troubled by the disparate complexity of the fifth postulate, and believed it could be proved as a theorem from the other four. Many attempted to find a proof by contradiction, including Ibn al-Haytham (Alhazen, 11th century), Omar Khayyám (12th century), Nasīr al-Dīn al-Tūsī (13th century), and Giovanni Girolamo Saccheri (18th century).
Richard Pipes, Russia under the Old Regime, page 65 He believed they came about through conquest and were common in Africa and Asia. Modern and Contemporary Hungarian academics support the postulate that in the Middle Ages the Kingdom of Hungary existed as a "patrimonial kingdom" (in Hungarian Language: Patrimoniális királyság) where the King was the supreme owner of the Kingdom's lands. Indonesia, before and during the Suharto administration, is often cited as being patrimonial in its political-economy.Schwarz, Adam. 2004.
The largest of these seamounts is named Discovery Seamount, which given its shape might once have been an island. The seamount is covered with fossil-containing sediments, which have been used to infer paleoclimate conditions in the region during the Pleistocene. Some of the sediment appears to be ice-rafted debris, and other evidence has been used to postulate that the seamount subsided by about during the late Pleistocene. Another member of the Discovery Seamounts has been christened Shannon Seamount.
In the essay entitled "The Kekulé Problem" (2017), McCarthy analyzes a dream of August Kekulé's as a model of the unconscious mind and the origins of language. He theorizes about the nature of the unconscious mind and its separation from human language. The unconscious, according to McCarthy, "is a machine for operating an animal" and that "all animals have an unconscious." McCarthy goes on to postulate that language is purely a human cultural creation, and not a biologically determined phenomenon.
Another major work of Chang is a proposed experimental testing of whether there is a resting frame in the universe by measuring the particle masses. There is an unsolved conflict between the postulate of relativity and the quantum theories used in cosmology and particle physics today: The former assumes the universe does not have a resting frame, but the latter implies a resting frame exists. The famous Michelson–Morley experiment tested that for light, all inertial frames are equivalent, i.e.
Uthpalawarna Vishnu Devalaya in Devinuwara, Matara, Sri Lanka. While some Hindus consider Buddha as an incarnation of Vishnu, Buddhists in Sri Lanka venerate Vishnu as the custodian deity of Sri Lanka and protector of Buddhism. Vishnu is also known as Upulvan or Upalavarṇā, meaning 'Blue Lotus coloured'. Some postulate that Uthpala varna was a local deity who later merged with Vishnu while another belief is that Utpalavarṇā was an early form of Vishnu before he became a supreme deity in Puranic Hinduism.
The interconnectivity of nature is a key postulate in religious naturalism. Religious naturalism combines a naturalist worldview with ideals, perceptions, traditions, and values that have been traditionally associated with many religions or religious institutions. "Religious naturalism is a perspective that finds religious meaning in the natural world and rejects the notion of a supernatural realm." The term religious in this context is construed in general terms, separate from the traditions, customs, or beliefs of any one of the established religions.
Research in 2011 indicated that the rise in lake levels began 18,500 BP, peaking 16,000 and 14,500 years ago. About 14,200 years ago, lake levels dropped before rising again until 11,500 years ago. Some researchers postulate that the last phase of Lake Tauca may have continued until 8,500 BP. The drying of the lake, which may have occurred because of the Bølling-Allerød climate oscillation, left the salt deposits of Salar de Uyuni. Lake Tauca is one of several ancient lakes which formed in the Altiplano.
Other observations are that fish should be given a higher priority due to its high omega-3 content, and that high fat dairy products should be excluded. As an alternative, the authors postulate a new food pyramid, emphasising low glycemic-load vegetables, healthy fats, such as avocados, nuts and seeds, lean animal protein, fish, and extra virgin olive oil. The University of Michigan Integrative Medicine’s Healing Foods Pyramid emphasizes plant-based choices, variety and balance. It includes sections for seasonings and water as well as healthy fats.
Although much of the New math curriculum has been drastically modified or abandoned, the geometry portion has remained relatively stable. Modern high school textbooks use axiom systems that are very similar to those of the SMSG. For example, the texts produced by the University of Chicago School Mathematics Project (UCSMP) use a system which, besides some updating of language, differs mainly from the SMSG system in that it includes some transformation concepts under its "Reflection Postulate". There are only three undefined terms: point, line and plane.
Callen, H.B. (1960/1985), p. 26. (This postulate is sometimes, but not often, called the "minus first" law of thermodynamics. One textbookUhlenbeck, G.E., Ford, G.W. (1963), p. 5. calls it the "zeroth law", remarking that the authors think this more befitting that title than its more customary definition, which apparently was suggested by Fowler.) Such states are a principal concern in what is known as classical or equilibrium thermodynamics, for they are the only states of the system that are regarded as well defined in that subject.
At eleven years old he attended the course of the École Polytechnique as an auditor (open courses). From age eleven to seventeen, he obtained two bachelor's degrees, a license and a PhD with a thesis on the mathematical theory of electricity and is admitted first to the 1839 entrance examination of the École Polytechnique. He conjectured, in 1845, that there is at least one prime between n and 2n − 2 for every n > 3\. Chebyshev proved this conjecture, now called Bertrand's postulate, in 1850.
With Angelica de Oliveira-Costa and Andrew Hamilton, he discovered the anomalous multipole alignment in the WMAP data sometimes referred to as the "axis of evil". With Anthony Aguirre, he developed the cosmological interpretation of quantum mechanics. His 2000 paper on quantum decoherence of neurons concluded that decoherence seems too rapid for Roger Penrose's "quantum microtubule" model of consciousness to be viable. Tegmark has also formulated the "Ultimate Ensemble theory of everything", whose only postulate is that "all structures that exist mathematically exist also physically".
The First Moderns: Profiles in the Origins of Twentieth-Century Thought is a book on Modernism by historian William Everdell, published in 1997 by the University of Chicago Press. A New York Times Notable Book of 1997, and included by the New York Public Library on its list of "25 Books to Remember from 1997," The First Moderns suggests that "the heart of Modernism is the postulate of ontological discontinuity.""Notable Books of the Year 1997", The New York Times, December 7, 1997. Accessed July 11, 2017.
In other words, I postulate and suggest that the position must not be a family inheritance but a democratic traditional institution by virtue of the founding of the land in an organised Ẹgba Native Administration. It is time for the development of both Ijoko and Sango and bye bye to land merchandising, ọbaship tussle and acrimony. It is time for anybody who is who to come together as one to take part in development. This can never be possible without the rule of law in the land.
In addition to their influence with contemporaneous Mesoamerican cultures, as the first civilization in Mesoamerica, the Olmecs are credited, or speculatively credited, with many "firsts", including the bloodletting and perhaps human sacrifice, writing and epigraphy, and the invention of popcorn, zero and the Mesoamerican calendar, and the Mesoamerican ballgame, as well as perhaps the compass.See Carlson for details of the compass. Some researchers, including artist and art historian Miguel Covarrubias, even postulate that the Olmecs formulated the forerunners of many of the later Mesoamerican deities.Covarrubias, p. 27.
The anthropic principle proposes that fundamental constants may have the values they have because such values are necessary for life (and hence intelligent observers to measure the constants). The anthropic landscape thus refers to the collection of those portions of the landscape that are suitable for supporting intelligent life. In order to implement this idea in a concrete physical theory, it is necessary to postulate a multiverse in which fundamental physical parameters can take different values. This has been realized in the context of eternal inflation.
Most common are studies of proglottids passed in stool samples of infected hosts. Studies have shown that specimens collected from humans are essentially morphologically the same as specimens collected from monkey hosts, except for some anatomical differences in reproductive organs. However, these discrepancies in morphological findings have led researchers to postulate that there may be more than two human Bertiella species, as previously believed. These gravid proglottids in stool are white and can measure around 11 mm for maximum length and 8 mm for maximum width.
Winfried Seipel and Hermann Alexander Schlögl instead postulate that the historical figure behind Thamphthis could have been queen Khentkaus I.Wilfried Seipel: Untersuchungen zu den ägyptischen Königinnen der Frühzeit und des Alten Reiches. pp. 189–190. This theory is supported by Khentkaus being depicted in her mortuary temple as a ruling pharaoh with nemes-headdress, king's beard and uraeus-diadem on her forehead. But this theory is problematic since Khentkaus' name never appears inside a serekh or royal cartouche.Hermann Alexander Schlögl: Das Alte Ägypten. pp. 99–100.
The closest affinities were with the population of Tuscany. The investigators attribute this closer kinship to a major influx from there in the early and middle Neolithic, which they date to the 8th-6th millennia BCE. Subsequently, they postulate a population expansion in the Chalcolithic, which is substantiated by the distribution of Corsican artifacts throughout the Mediterranean. The separation of Corsican and non-Corsican populations falls within rather wide limits: no earlier than 19,000 BCE or later than 3000 BCE at latest, according to Tofanelli.
They called for new forms of legislation that would protect animals for non-anthropocentric reasons. In these discussions (of the moral relevance of the animal's welfare) two key issues were involved. To begin with, the Harm principle, rather than the Offence principle, should be the moral foundation for the protection of animals. Secondly, as to the scepticism expressed by scientists regarding the presence of consciousness and self-awareness in animals, they should be granted the benefit of the doubt by adopting the so-called analogy postulate.
The first postulate of special relativity theory that the speed of light in vacuum is the same to all inertial observers (i.e. it is a constant, and therefore a good measure of length). Of interest, this theoretical concept is the basis of an operational definition for the length of a metre is "the distance traveled by light in a vacuum during a time interval of 1/299,792,458 of a second". Thus we have defined 'metre' according to other ideas contained in modern scientific theory.
A typical example is Maxwell's equations. Another is Newton's first law. 1\. First Postulate (Principle of relativity) : Under transitions between inertial reference frames, the equations of all fundamental laws of physics stay form- invariant, while all the numerical constants entering these equations preserve their values. Thus, if a fundamental physical law is expressed with a mathematical equation in one inertial frame, it must be expressed by an identical equation in any other inertial frame, provided both frames are parameterised with charts of the same type.
Probability of binding for the T7 (green) and Lac Ecoli (blue) promoters by RNA polymerase concentrations.The process of binding is central in determining the "strength" of promoters, that is the relative estimation of how "well" a promoter perform the expression of a gene under specific circumstances. Brewster et al., using a simple thermodynamical model based on the postulate that transcriptional activity is proportional to the probability of finding the RNA polymerase bound at the promoter, obtained predictions of the scaling of the RNA polymerase binding energy.
Dzierżyńszczyzna was disbanded in 1937. All Polish schools and libraries were closed, Tomasz Dąbal was executed in 1938. After World War II, in both Polish and Soviet historiographies, the existence of the districts was omitted, perhaps because the authorities of both countries wanted to avoid uneasy questions about sudden rejection of the Leninist postulate of the rights of nations for self- determination. The area of Marchlewszczyzna is still inhabited by the Polish minority, in the town of Dovbysh they make half of the population.
Poznan: Poznan Archaeological Museum. Retrieved March 12, 2010. Studies of the ichthyo-fauna in Mesolithic sites in Central Sudan and lower Atbara published in 1993 led Peters to postulate that well designed Nile boats were used to fish for adults of the open water species Synodotis, Bagrus and Lates on a regular basis as opposed to fortuitous situations that occur in seasonal flood pools. Lates is the infamous Nile Perch that can grow to 6'7” (2m) in length and 200 kg (440 lb) in weight.
The original inhabitants were the Barmerara Meru clan of the Ngawadj people. It is not known where the name "Barmera" comes from but it is suspected that it means "water place" or "land dwellers", being a word from the local Aboriginal group. Others postulate it comes from Barmeedjie, the name of the tribe that lived to the north of the Murray River prior to European settlement. Lake Bonney was first seen by Charles Bonney and Joseph Hawdon in 1838 drove cattle along the Murray River.
In quantum physics, unitarity is the condition that the time evolution of a quantum state according to the Schrödinger equation is mathematically represented by a unitary operator. This is typically taken as an axiom or basic postulate of quantum mechanics, while generalizations of or departures from unitarity are part of speculations about theories that may go beyond quantum mechanics. A unitarity bound is any inequality that follows from the unitarity of the evolution operator, i.e. from the statement that time evolution preserves inner products in Hilbert space.
The Demos group, a think tank in the United Kingdom, is among the academic institutions that have suggested that satire can be an effective tool in undermining support for violent jihad. According to some terrorism experts, successful recruitment for violent jihad depends upon convincing potential recruits that jihadis are "pious warriors of God". They postulate that by "highlighting their incompetence, their moral failings, and their embarrassing antics", it may be possible to "undermine" support for violent jihadi organizations including Al Qaeda and the Taliban.
Over 100 years ago, Thoma observed that increases in local blood flow cause widening of the vessel diameter and he even went so far as to postulate that blood flow might be responsible for the growth and development of blood vessels Thoma, R. (1893). Untersuchungen ü ber die Histogenese und Histo- mechanik des 1186 Gefä ßsystems. Stuttgart, Germany: Ferdinand Enke . Subsequently, Chapman in 1918 discovered that removing a chick embryo's heart disrupted the remodelling process, but the initial vessel patterns laid down by vasculogenesis remained undisturbed.
The various Hindu schools and traditions give various interpretations of the Vedic hymns. Mīmāṃsā philosophers argue that there was no need to postulate a maker for the world, just as there was no need for an author to compose the Vedas or a god to validate the rituals. Mīmāṃsā argues that the gods named in the Vedas have no existence apart from the mantras that speak their names. To that regard, the power of the mantras is what is seen as the power of gods.
Thomas S. Kuhn, The Structure of Scientific Revolutions: 50th Anniversary Edition, University of Chicago Press, 2012, p. xl. In La Déduction relativiste, Meyerson expressed the view that Einstein's general theory of relativity was a new version of the identification of matter with space, which he considered "the postulate upon which the whole (Cartesian) system rests."Quoted in Arthur O. Lovejoy, The Revolt against Dualism: An Inquiry Concerning the Existence of Ideas (New Brunswick, NJ: Transaction Publishers, 1996), p. 5; Lovejoy's translation [orig. publ. 1930].
Mīmāṃsā theorists decided that the evidence allegedly proving the existence of God was insufficient. They argue that there was no need to postulate a maker for the world, just as there was no need for an author to compose the Vedas or a God to validate the rituals. Mīmāṃsā argues that the Gods named in the Vedas have no existence apart from the mantras that speak their names. To that regard, the power of the mantras is what is seen as the power of Gods.
He believed that it was not a question of physics, but one of philosophy or convenience. ": "[T]he quantum postulate implies that any observation of atomic phenomena will involve an interaction with the agency of observation not to be neglected. Accordingly, an independent reality in the ordinary physical sense can neither be ascribed to the phenomena nor to the agencies of observation. After all, the concept of observation is in so far arbitrary as it depends upon which objects are included in the system to be observed.
Stars in bound systems must obey the virial theorem. The theorem, together with the measured velocity distribution, can be used to measure the mass distribution in a bound system, such as elliptical galaxies or globular clusters. With some exceptions, velocity dispersion estimates of elliptical galaxies do not match the predicted velocity dispersion from the observed mass distribution, even assuming complicated distributions of stellar orbits. As with galaxy rotation curves, the obvious way to resolve the discrepancy is to postulate the existence of non-luminous matter.
TdTL1 is broadly expressed in lymphoid cell lines while TdTL2 is predominantly expressed in normal small lymphocytes. Both localize in the nucleus when expressed and both possess 3'->5' exonuclease activity. In contrast, TdTS isoforms do not possess exonuclease activity and perform the necessary elongation during V(D)J recombination. Since a similar exonuclease activity hypothesized in murine TdTL is found in human and bovine TdTL, some postulate that bovine and human TdTL isoforms regulate TdTS isoforms in a similar manner as proposed in mice.
Second, natural capital is often undervalued by society since we are not fully aware of the real cost of the depletion of natural capital. Information asymmetry is a third reason—often the link between cause and effect is obscured, making it difficult for actors to make informed choices. Cohen and Winn close with the realization that contrary to economic theory many firms are not perfect optimisers. They postulate that firms often do not optimise resource allocation because they are caught in a "business as usual" mentality.
If not, then one is greater than the other, which implies its supplement is less than the supplement of the other angle. This implies that there are interior angles on the same side of the transversal which are less than two right angles, contradicting the fifth postulate. The proposition continues by stating that on a transversal of two parallel lines, corresponding angles are congruent and the interior angles on the same side are equal to two right angles. These statements follow in the same way that Prop.
Starting out from these premises, Bahnsen found Hegel's idea of the dialectic appealing. The dialectic explained the ingrained opposition of the world with itself in a cycle of perpetual conflict (as Heraclitus had observed in his fragments centuries earlier). However, Bahnsen believed that Heraclitus's postulate of an underlying Logos and Hegel's idea of the rational spirit had misled them and had contaminated Hegel's formulation of the dialectic with progressivism and historicism. As a response to this "misunderstanding", Bahnsen developed his own idea of the Realdialektik.
Americans have never had this system.Drawing the wrong conclusions from British English, some commentators postulate a fellowship in 1891 followed by some sort of tutorship in 1893. The evidence is that Marett was never in the “Ordinary” position, but started as a Tutor. As to how he may have obtained the position, he says in his autobiography that all he asks of the historian is that he be classified as “even the least of ‘Jowett’s men,' referring to the long-standing Master of Balliol College.
The insights gained from his study of Blake set Frye on his critical path and shaped his contributions to literary criticism and theory. He was the first critic to postulate a systematic theory of criticism, "to work out," in his own words, "a unified commentary on the theory of literary criticism" (Stubborn Structure 160). In so doing, he shaped the discipline of criticism. Inspired by his work on Blake, Frye developed and articulated his unified theory ten years after Fearful Symmetry, in the Anatomy of Criticism (1957).
Instead of being content with the postulate of parallelism, he developed his principles of mental causality in contrast to the natural causality of neurophysiology, and a corresponding methodology. There are two fundamentally different approaches of the postulated psychophysical unit, not just two points-of-view in the sense of Gustav Theodor Fechner's identity hypothesis. Psychological and physiological statements exist in two categorically different reference systems; the important categories are to be emphasised in order to prevent category mistakes as discussed by Nicolai Hartmann.Nicolai Hartmann.
Einstein, H. A. Lorentz, H. Weyl, H. Minkowski, The Principle of Relativity, Dover Publications, Inc, 2000, softcover 216 pages, , See pp. 37–65 for an English translation of Einstein's original 1905 paper. postulated the constancy and finiteness of the speed of light for all observers. He showed that this postulate, together with a reasonable definition for what it means for two events to be simultaneous, requires that distances appear compressed and time intervals appear lengthened for events associated with objects in motion relative to an inertial observer.
This class of theories attempts to come up with an all-encompassing theory of both dark matter and dark energy as a single phenomenon that modifies the laws of gravity at various scales. This could, for example, treat dark energy and dark matter as different facets of the same unknown substance,See dark fluid. or postulate that cold dark matter decays into dark energy. Another class of theories that unifies dark matter and dark energy are suggested to be covariant theories of modified gravities.
The coalescence age for the human variations of the MUC7 gene is estimated to be around 4.5 million years ago, which predates the human- Neanderthal split. Neanderthals and Denisovans also carry variants that are much closer to those of other, modern humans; thus, researchers postulate that this divergent Sub-Saharan variant most likely introgressed from a currently yet-unknown archaic human ghost population. 50px This article contains quotations from this source, which is available under the Creative Commons Attribution 4.0 International (CC BY 4.0) license.
Gene-culture coevolution allows humans to develop highly distinct adaptations to the local pressures and environments more quickly than with genetic evolution alone. Robert Boyd and Peter J. Richerson, two strong proponents of cultural evolution, postulate that the act of social learning, or learning in a group as done in group selection, allows human populations to accrue information over many generations.Boyd, R., & Richerson, P. J. (2009) Culture and the evolution of human cooperation. This leads to cultural evolution of behaviors and technology alongside genetic evolution.
499 The precedent takes special significance in cases that the federal government attempts to limit private conduct. Commentators still postulate its possible effects on other established federal laws enacted pursuant to the Commerce Clause. The argument can be made that the significant limiting of federal power is necessary to establish a greater threshold for governmental accountability and revitalizes the role of the states in public policymaking. It can also be ascribed to new legislation that makes open carry in schools legal in some Texas jurisdictions.
Nasir al-Din's son, Sadr al-Din (sometimes known as "Pseudo-Tusi"), wrote a book on the subject in 1298, based on his father's later thoughts, which presented one of the earliest arguments for a non- Euclidean hypothesis equivalent to the parallel postulate. "He essentially revised both the Euclidean system of axioms and postulates and the proofs of many propositions from the Elements."Boris A. Rosenfeld and Adolf P. Youschkevitch (1996), "Geometry", in Roshdi Rashed, ed., Encyclopedia of the History of Arabic Science, Vol.
Jevons warned that fuel efficiency gains tend to increase fuel use. However, this does not imply that improved fuel efficiency is worthless if the Jevons paradox occurs; higher fuel efficiency enables greater production and a higher material quality of life. For example, a more efficient steam engine allowed the cheaper transport of goods and people that contributed to the Industrial Revolution. Nonetheless, if the Khazzoom–Brookes postulate is correct, increased fuel efficiency, by itself, will not reduce the rate of depletion of fossil fuels.
Characterization of the RRNPP family of quorum sensing regulators (which stands for proteins Rap, NprR, PrgX, PlcRd) were used in comparisons with RopB to postulate its structural functions. The Rap protein derived from Bacilli regulates sporulation, the NprR protein in Bacillus thuringiensis regulates necrotrophism, the PrgX protein regulates conjugation in Enterococcus faecalis, and PlcR protein regulates transcription of virulence factors in both Bacullis thuringiensis and Bacillus cereus. Similarities were observed in conserved asparagine residues on the TPR motifs of each of these proteins and in RopB.
In 1916 Arthur Dempster showed that H3 gas was unstable, but at the same time also confirmed that the cation existed. In 1917 Gerald Wendt and William Duane discovered that hydrogen gas subjected to alpha particles shrank in volume and thought that diatomic hydrogen was converted to triatomic. After this researchers thought that active hydrogen could be the triatomic form. Joseph Lévine went so far as to postulate that low pressure systems on the Earth happened due to triatomic hydrogen high in the atmosphere.
Some scholars postulate that in pre-Islamic Arabia, including in Mecca, Allah was considered to be a deity, possibly a creator deity or a supreme deity in a polytheistic pantheon. The word Allah (from the Arabic al-ilah meaning "the god") may have been used as a title rather than a name. The concept of Allah may have been vague in the Meccan religion. According to Islamic sources, Meccans and their neighbors believed that the goddesses Al-lāt, Al-‘Uzzá, and Manāt were the daughters of Allah.
Lines through a given point P and asymptotic to line R A triangle immersed in a saddle-shape plane (a hyperbolic paraboloid), along with two diverging ultra-parallel lines In mathematics, hyperbolic geometry (also called Lobachevskian geometry or Bolyai–Lobachevskian geometry) is a non-Euclidean geometry. The parallel postulate of Euclidean geometry is replaced with: :For any given line R and point P not on R, in the plane containing both line R and point P there are at least two distinct lines through P that do not intersect R. :(compare this with Playfair's axiom, the modern version of Euclid's parallel postulate) Hyperbolic plane geometry is also the geometry of saddle surfaces and pseudospherical surfaces, surfaces with a constant negative Gaussian curvature. A modern use of hyperbolic geometry is in the theory of special relativity, particularly Minkowski spacetime and gyrovector space. When geometers first realised they were working with something other than the standard Euclidean geometry, they described their geometry under many different names; Felix Klein finally gave the subject the name hyperbolic geometry to include it in the now rarely used sequence elliptic geometry (spherical geometry), parabolic geometry (Euclidean geometry), and hyperbolic geometry.
Hvaniratha is believed to be "central one" and whose size was as large as all others together. p.95.The karshvar Hvaniratha is where "peak of Hara" (Alburz) had "grown from the roots of Elburz mountains". Sufi traditions postulate an eighth clime, the "heavenly Earth" or "cosmic North". In Theosophy, according to H. P. Blavatsky (The Devil's Own, 1891), Ahura is interpreted as a generic name for the sevenfold Deity, the Ruler of the Seven Worlds, and Hvaniratha is the middle plane (the fourth of seven), corresponding to Earth.
In addition to removing ambiguity from previously naive terms such as function, it was hoped that this axiomatization would allow for consistency proofs. In the 19th century, the main method of proving the consistency of a set of axioms was to provide a model for it. Thus, for example, non-Euclidean geometry can be proved consistent by defining point to mean a point on a fixed sphere and line to mean a great circle on the sphere. The resulting structure, a model of elliptic geometry, satisfies the axioms of plane geometry except the parallel postulate.
Lake Cheko is roughly north-northwest of the epicenter of the Tunguska event.The Tunguska Mystery--100 Years Later The lake is inside the blast zone, and in the probable direction of whatever made the Tunguska event. It has been connected by some scientists to the Tunguska event and they postulate the lake was created by a chunk of the exploding meteorite that struck the ground. In 2017, that theory was disputed by Russian scientists by proving that the lake is older, possibly even much older, than the Tunguska Event.
RCT found that in blood samples taken after bouts of exhaustive exercise, there was a reduced response to an infectious stimulus in the placebo group, but the MSM group maintained a robust response, indicating that MSM protected against stress-induced immunosuppression. The authors postulate that MSM’s anti-inflammatory properties reduce the over stimulation of inflammatory cells during exercise, thus conserving the their ability to respond to infections threats. This is supported by in vitro research showing MSM inhibits over-activation of white blood cells and has an anti-apoptotic effect.
The names of both these towns were theorized to be cognates of Gambrivius, as one of Hamburg's ancient Latin names was alleged to be Gambrivium. One of Aventinus' sources was Officina (1503), an encyclopedia compiled by French scholar Jean Tixier de Ravisi. This work purported that Tuisto and Gambrivius were giants descended from Noah. But Jean Tixier had only catalogued and reported a conjecture made in the name of the Hellenistic- era historian Berossus, by the fraudster Annio da Viterbo (1498), who had previously used the same hypothesis to postulate an ancestry for the Gauls.
But kings such as "Nubnefer", "Bird" and "Za" remain a mystery. They never appear anywhere else in the historical record other than at Saqqara where the number of objects surviving from their lifetimes is very limited. Schlögl, Helck and Peter Kaplony postulate that Nubnefer, Za and Bird were the corresponding rulers to Peribsen and Sekhemib and ruled in Lower Egypt, whilst the latter two ruled Upper Egypt.Peter Kaplony: A building named "Menti-Ankh". In: Mitteilungen des Deutschen Archäologischen Instituts Kairo (MDAIK), volume 20. de Gruyter, Berlin 1965, page 1–46.
A second case occurs a few days later, another man killed by the beetles, but they find the beetles to be larger and more mature. From the second victim's movements, they identify the likely culprit as Dr. Armand Silva (Alon Abutbul), a former scientist. Dr. Silva was working on a cure for avian flu using the skelter beetle, but his research was terminated with the extinction of the sheep. Fauxlivia and Frank postulate Dr. Silva may be trying to breed the beetles in humans, who share similar biological features with sheep.
Leon Sapieha, the first speaker of the Seym of the Estates of Galicia. Count Agenor Romuald Gołuchowski. Parts of the Polish–Lithuanian Commonwealth Lesser Poland territories were included in the Austrian partition as early as the First Partition of Poland in 1772. In order to reduce dissent, the Austrian Empire in 1775 allowed the Polish nobility (szlachta) of the newly acquired territories to continue their tradition of holding local parliament-like meetings, and gave the permission for an advisory body, the Postulate Sejm (), to be held every year.
In Skyrme's model, reproduced in the large N or string approximation to quantum chromodynamics (QCD), the proton and neutron are fermionic topological solitons of the pion field. Whereas Skyrme's example involved pion physics, there is a much more familiar example in quantum electrodynamics with a magnetic monopole. A bosonic monopole with the smallest possible magnetic charge and a bosonic version of the electron will form a fermionic dyon. The analogy between the Skyrme field and the Higgs field of the electroweak sector has been used to postulate that all fermions are skyrmions.
Therefore, by definition, the transition state for tertiary reactions will be at a lower energy than for secondary reactions. However, the BEP principle cannot justify why the energy is lower. Using Hammond's postulate, the lower energy of the tertiary transition state means that its structure is relatively closer to its reactants R(tertiary)-X than to the carbocation product when compared to the secondary case. Thus, the tertiary transition state will be more geometrically similar to the R(tertiary)-X reactants than the secondary transition state is to its R(secondary)-X reactants.
Energy diagrams of SN1 reactions Hammond's postulate can be used to examine the structure of the transition states of a SN1 reaction. In particular, the dissociation of the leaving group is the first transition state in a SN1 reaction. The stabilities of the carbocations formed by this dissociation are known to follow the trend tertiary > secondary > primary > methyl. Therefore, since the tertiary carbocation is relatively stable and therefore close in energy to the R-X reactant, then the tertiary transition state will have a structure that is fairly similar to the R-X reactant.
In general, all models postulate the existence of a saliency or priority map for registering the potentially interesting areas of the retinal input, and a gating mechanism for reducing the amount of incoming visual information, so that the limited computational resources of the brain can handle it. An example theory that is being extensively tested behaviorally and physiologically is the hypothesis of a bottom-up saliency map in the primary visual cortex. Computational neuroscience provides a mathematical framework for studying the mechanisms involved in brain function and allows complete simulation and prediction of neuropsychological syndromes.
Primary functions are to supply information about structures, relative stabilities and other properties of isolated molecules. Molecular mechanics calculations on complex molecules are common in the chemical community. Quantum chemical calculations, including Hartree–Fock method molecular orbital calculations, but especially calculations that include electronic correlation, are more time-consuming in comparison. Quantum chemical calculations are also called upon to furnish information about mechanisms and product distributions of chemical reactions, either directly by calculations on transition states, or based on Hammond's postulate, by modeling the steric and electronic demands of the reactants.
In an attempt to explain human violence, Koestler criticizes the dominant conceptions of psychology of his time (behaviorism) that postulate that human behaviors are subject to the selection of the fittest. For him this theory echoed the Darwinian conceptions of the evolution of species. The book contributes also to the longstanding debate surrounding the mind–body problem and focusing in particular on René Descartes's dualism, in the form elucidated by Ryle. Koestler's materialistic account argues that the personal experience of duality arises from what Koestler calls a holon.
According to legend, Bataille and the other members of Acéphale each agreed to be the sacrificial victim as an inauguration; none of them would agree to be the executioner. An indemnity was offered for an executioner, but none was found before the dissolution of Acéphale shortly before the war. The group also published an eponymous review of Nietzsche's philosophy which attempted to postulate what Derrida has called an "anti-sovereignty". Collaborators in these projects included André Masson, Pierre Klossowski, Roger Caillois, Jules Monnerot, Jean Rollin and Jean Wahl.
The domes of Saint Basil's Cathedral have not been altered since the reign of Ivan's son Fyodor I (), indicating the presence of onion domes in the sixteenth-century Russia. Some scholars postulate that the Russians borrowed onion domes from Muslim countries, possibly from the Khanate of Kazan, whose conquest in 1552 Ivan the Terrible commemorated by erecting St. Basil's Cathedral. Eight of the nine domes featured on St. Basil's Cathedral represent each attack on Kazan. The ninth dome was constructed 36 years after the siege of Kazan as a tomb for Ivan.
This leads to another similarity between HSM and ELM, as attitudes and opinions developed through heuristic processing will tend to be "less stable, less resistant to counter-propaganda, and less predictive of behavior" in comparison to attitudes and opinions formed through detailed information within systematic processing (p. 327). HSM postulates that heuristic and systematic processing can each influence both "independent" and "interdependent" effects on decision making by occurring simultaneously (p. 328). Unlike HSM, ELM does not postulate whether central route processing and peripheral route processing can co-occur or not.
During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Gauss' Theorema Egregium (remarkable theorem) that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in an Euclidean space. This implies that surfaces can be studied intrinsically, that is as stand alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geometries without the parallel postulate (non-Euclidean geometries) can be developed without introducing any contradiction.
The center derives its name from the pathologist Rudolf Virchow, who was a professor in Würzburg from 1849 to 1856 and was the first to postulate that diseases originated in dysfunctions of cells. Researchers at the Rudolf Virchow Center aim to trace diseases back to dysfunctions of proteins. These are called target proteins because they may serve as targets for diagnostic tools or for therapeutic drugs. Research is organized in four fields: (1) Protein structure and function (2) Proteins in cellular signaling (3) Nucleic acid-binding proteins (4) Proteins in cell-cell interactions.
A computation can be seen as a purely physical phenomenon occurring inside a closed physical system called a computer. Examples of such physical systems include digital computers, mechanical computers, quantum computers, DNA computers, molecular computers, microfluidics-based computers, analog computers, or wetware computers. This point of view has been adopted by the physics of computation, a branch of theoretical physics, as well as the field of natural computing. An even more radical point of view, pancomputationalism, is the postulate of digital physics that argues that the evolution of the universe is itself a computation.
The pulse mode is more complex to model and numerous detailed neuron models and population models are described by Gerstner and Kistler in Parts I and II of Gerstner, W., & Kistler, W. (2002) and Chapter 8 of Sterratt, D., Graham, B., Gillies, A., & Willshaw, D. (2011). Another important characteristic associated with SR model is the spike-time-dependent-plasticity. It is based on Hebb's postulate on plasticity of synapse, which states that "the neurons that fire together wire together". This causes the synapse to be a long-term potentiation (LTP) or long-term depression (LTD).
George Simms Hammond (May 22, 1921 – October 5, 2005) was an American scientist and theoretical chemist who developed "Hammond's postulate", and fathered organic photochemistry,–the general theory of the geometric structure of the transition state in an organic chemical reaction. Hammond's research is also known for its influence on the philosophy of science. His research garnered him the Norris Award in 1968, the Priestley Medal in 1976, the National Medal of Science in 1994,"Obituaries", C&EN;, 83(48), 46 (November 28, 2005). and the Othmer Gold Medal in 2003.
Energy diagrams of SN1 reactions Hammond's postulate can be used to examine the structure of the transition states of a SN1 reaction. In particular, the dissociation of the leaving group is the first transition state in a SN1 reaction. The stabilities of the carbocations formed by this dissociation are known to follow the trend tertiary > secondary > primary > methyl. Therefore, since the tertiary carbocation is relatively stable and therefore close in energy to the R-X reactant, then the tertiary transition state will have a structure that is fairly similar to the R-X reactant.
Therefore, by definition, the transition state for tertiary reactions will be at a lower energy than for secondary reactions. However, the BEP principle cannot justify why the energy is lower. Using Hammond's postulate, the lower energy of the tertiary transition state means that its structure is relatively closer to its reactants R(tertiary)-X than to the carbocation "product" when compared to the secondary case. Thus, the tertiary transition state will be more geometrically similar to the R(tertiary)-X reactants than the secondary transition state is to its R(secondary)-X reactants.
This 'Pneumatic' thrust in the Spiritual Homilies is often termed 'mystical' and as such is a spiritual mode of thought which has endeared him to Christian mystics of all ages, although, on the other hand, in his anthropology and soteriology he frequently approximates the standpoint of St. Augustine. Certain passages of his homilies assert the entire depravity of man, while others postulate free will, even after the fall of Adam, and presuppose a tendency toward virtue, or, in semi-Pelagian fashion, ascribe to man the power to attain a degree of readiness to receive salvation.
Psychosynthesis is an approach to psychology that expands the boundaries of the field by identifying that a deeper center of identity, which is the postulate of the Self. It considers each individual unique in terms of purpose in life and places value on the exploration of human potential. The approach combines spiritual development with psychological healing by including the life journey of an individual or his unique path to self-realization. The integrative framework of psychosynthesis is based on Sigmund Freud's theory of the unconscious and addresses psychological distress and intra-psychic and interpersonal conflicts.
It was also observed that the 2-exo-substituted norbornanes reacted 350 times faster than the corresponding endo isomers. Anchimeric assistance of the sigma bond between carbons 1 and 6 was rationalized as the explanation for this kinetic effect. Importantly, the invoked anchimeric assistance led many chemists to postulate that the energetic stability of the 2-norbornyl cation was directly due to the symmetric, bridged structure invoked in the non-classical explanation. However, some other authors offered alternative explanations for the high stability without invoking a non-classical structure.
John Playfair FRSE, FRS (10 March 1748 – 20 July 1819) was a Church of Scotland minister, remembered as a scientist and mathematician, and a professor of natural philosophy at the University of Edinburgh. He is best known for his book Illustrations of the Huttonian Theory of the Earth (1802), which summarised the work of James Hutton. It was through this book that Hutton's principle of uniformitarianism, later taken up by Charles Lyell, first reached a wide audience. Playfair's textbook Elements of Geometry made a brief expression of Euclid's parallel postulate known now as Playfair's axiom.
Map of ankylosaurine distribution across North America in the Late Cretaceous It is difficult to establish the geographical origin of Ankylosauridae at present. There is a mix of basal ankylosaurids from both North America and Asia, which carries on through accepted cladistic analyses. It appears that in the mid- Cretaceous, Asian nodosaurids were replaced by ankylosaurine ankylosaurids. Some researchers postulate that Ankylosaurines migrated into North America from Asia between the Albian and Campanian, where they diversified into a clade of ankylosaurines characterized by arched snouts and flat cranial bone plates (caputegulae).
289 Binswanger's Dream and Existence — which was translated from German into French by Michel Foucault who added a substantial essay-introduction — highlighted in similar fashion the necessity of "steeping oneself in the manifest content of the dream - which, since Freud's epoch- making postulate concerning the reconstruction of latent thoughts, has in modern times receded all to[o] far into the background".Quoted in May, p. 289 Eugène Minkowski had earlier introduced Binswanger's ideas into France, influencing thereby among others the early work of Jacques Lacan.Elisabeth Roudinesco, Jacques Lacan (2005) p.
Historically, system identification for nonlinear systemsNelles O. "Nonlinear System Identification: From Classical Approaches to Neural Networks". Springer Verlag,2001Billings S.A. "Nonlinear System Identification: NARMAX Methods in the Time, Frequency, and Spatio-Temporal Domains". Wiley, 2013 has developed by focusing on specific classes of system and can be broadly categorised into five basic approaches, each defined by a model class: # Volterra series models, # Block-structured models, # Neural network models, # NARMAX models, and # State-space models. There are four steps to be followed for system identification: data gathering, model postulate, parameter identification and model validation.
Chaos Theory is a concept taken from the physical sciences. It challenges models that postulate linear and sequential processes, and instead suggests that development is inherently unpredictable. Chaos theory argues that it's unrealistic for a system to go through deterministic, predictable, and repeated stages. It was first applied to group development literature by McClure (1998) to suggest how groups never repeats themselves in the 'exact' same way, but that teams go through periods of chaos where the trajectory of the group is determined through conflict, turbulence, and uncertainty.
Anthropologists such as Vombruck postulate that Yemen's history and social hierarchy that developed under various regimes, including the Zaydi Imamate, had created a hereditary caste-like society. Today, the Al-Akhdam people still exist at the very bottom of Yemeni social strata. In the mid-20th century, the Akhdam people who lived in the vicinity of al-Gades (an exclusive Jewish village) were given the name "Kano" by Jews. While a Shafi'i Lowland Muslim would eat from the same dish as a Jew, he would break a vessel touched by one of the Akhdam.
Equal weights at equal distances. In postulate one Archimedes states that "Equal weights at equal distances are in equilibrium" (meaning one equal weight on either side of the lever arm). At propositions four, and five, he expands this observation to include the concept of the centre of gravity; wherein it is proven that the centre of gravity of any system consisting of an even number of equal weights, equally distributed, will be located at the midpoint between the two centre weights (hence introducing multiple weights on either side of the lever arm).
Researchers are divided on whether menstrual synchrony would be adaptive. McClintock has suggested that menstrual synchrony may not be adaptive but rather epiphenomenonal, lacking any biological function. Among those who postulate an adaptive function, one argument is that menstrual synchrony is only a particular aspect of the much more general phenomenon of reproductive synchrony, an occurrence familiar to ecologists studying animal populations in the wild. Whether seasonal, tidal or lunar, reproductive synchrony is a relatively common mechanism through which co-cycling females can increase the number of males included in the local breeding system.
Leon Ong Chua (; ; born June 28, 1936) is an American electrical engineer and computer scientist. He is a professor in the electrical engineering and computer sciences department at the University of California, Berkeley, which he joined in 1971. He has contributed to nonlinear circuit theory and cellular neural network (CNN) theory. He is also the inventor and namesake of Chua's circuit one of the first and most widely known circuits to exhibit chaotic behavior, and was the first to conceive the theories behind, and postulate the existence of, the memristor.
The Oblates of St. Francis de Sales offer an Associate Program, designed to help young men discern a possible call to religious life and priesthood during their college years. The Postulate period lasts for a year, during which the candidate with and participates in the life of an Oblate community, in order to smooth the transition from his present lifestyle to Oblate community living. The one-year Novitiate is taken up with studies, particularly Salesian spirituality. For the first three years following first vows, Oblate renew their vows annually, and then profess perpetual vows.
Basal stem rot (BSR), caused by the fungus Ganoderma, is the most serious disease of oil palm in Malaysia and Indonesia. Previously, research on basal stem rot was hampered by the failure to artificially infect oil palms with the fungus. Although Ganoderma had been associated with BSR, proof of its pathogenicity to satisfy Koch's postulate was only achieved in the early 1990s by inoculating oil palm seedling roots or by using rubber wood blocks. A reliable and quick technique was developed for testing the pathogenicity of the fungus by inoculating oil palm germinated seeds.
However, the identity of the mother is an unsolved mystery. Some scholars speculate that her true mother was actually Claire Clairmont or Elise Foggi, a nursemaid for the Shelley family. Other scholars postulate that she was a foundling Shelley adopted in hopes of distracting Mary after the death of Clara.. Shelley referred to Elena in letters as his "Neapolitan ward". However, Elena was placed with foster parents a few days after her birth and the Shelley family moved on to yet another Italian city, leaving her behind. Elena died 17 months later, on 10June 1820.
Theme- centered interaction is being used in diverse applications: in management, in the university, in psychological guidance and therapy, in supervision, in education, in social and special pedagogy, in adult education, in pastoral care, in care of patients, etc. It is the explicit goal of TCI not only to support the leader, but also to enable a group to lead itself (chair person postulate). In his Ph.D. thesis, Friedrich Ewert Ewert: Themenzentrierte Interaktion (TZI) und pädagogische Professionalität von Lehrerinnen und Lehrern, Erfahrungen und Reflexionen. VS Research, Wiesbaden 2008, .
She also published a number of novels, including: The Letters of Elżbieta Rzeczycka to her friend Urszula (1824) and, arguably her best known work, The Diary of Countess Francoise Krasinska (1825), translated into several languages, and recounted as one of the first Polish psychological novels. Hoffmanowa raised the postulate of economic self-empowerment of women. She believed that the first step for women to achieve independence should be gaining education to enable paid work. However, she held conservative views on the role of women and referred to national and Catholic values.
Test theories of special relativity give a mathematical framework for analyzing results of experiments to verify special relativity. An experiment to test the theory of relativity cannot assume the theory is true, and therefore needs some other framework of assumptions that are wider than those of relativity. For example, a test theory may have a different postulate about light concerning one-way speed of light vs. two-way speed of light, it may have a preferred frame of reference, and may violate Lorentz invariance in many different ways.
A state is characterized by that as the particle content is that represented collectively by . Likewise, a state will have the particle content represented by for . Using the assumption that the in and out states, as well as the interacting states, inhabit the same Hilbert space and assuming completeness of the normalized in and out states (postulate of asymptotic completeness), the initial states can be expanded in a basis of final states (or vice versa). The explicit expression is given later after more notation and terminology has been introduced.
A considerable amount has been written on how Higgs' name came to be exclusively used. Two main explanations are offered. The first is that Higgs undertook a step which was either unique, clearer or more explicit in his paper in formally predicting and examining the particle. Of the PRL papers' authors, only the paper by Higgs explicitly offered as a prediction that a massive particle would exist and calculated some of its properties; he was therefore "the first to postulate the existence of a massive particle" according to Nature.
This 60-year-old female had a left RCC with multiple lung metastases and a left femoral bone metastasis at the time of diagnosis. After left nephrectomy followed by immunotherapy, we performed tumour excision and reconstruction with frozen recycled autograft. The lung metastases had disappeared by 10 months after surgery, while serum levels of interferon-gamma and interleukin-12 had increased. We postulate that the antitumour activity resulted from immunotherapy plus cryotreatment of her bone metastasis and believe that this case supports continued research into immunotherapy for cancer.
Broadly, this allows classification of LTP into Hebbian, non-Hebbian, and anti-Hebbian mechanisms. Borrowing its name from Hebb's postulate, summarized by the maxim that "cells that fire together wire together," Hebbian LTP requires simultaneous pre- and postsynaptic depolarization for its induction. Non-Hebbian LTP is a type of LTP that does not require such simultaneous depolarization of pre- and postsynaptic cells; an example of this occurs in the mossy fiber hippocampal pathway. A special case of non-Hebbian LTP, anti-Hebbian LTP explicitly requires simultaneous presynaptic depolarization and relative postsynaptic hyperpolarization for its induction.
In most cases, a non-logical axiom is simply a formal logical expression used in deduction to build a mathematical theory, and might or might not be self-evident in nature (e.g., parallel postulate in Euclidean geometry). To axiomatize a system of knowledge is to show that its claims can be derived from a small, well-understood set of sentences (the axioms), and there may be multiple ways to axiomatize a given mathematical domain. Any axiom is a statement that serves as a starting point from which other statements are logically derived.
Axioms play a key role not only in mathematics, but also in other sciences, notably in theoretical physics. In particular, the monumental work of Isaac Newton is essentially based on Euclid's axioms, augmented by a postulate on the non-relation of spacetime and the physics taking place in it at any moment. In 1905, Newton's axioms were replaced by those of Albert Einstein's special relativity, and later on by those of general relativity. Another paper of Albert Einstein and coworkers (see EPR paradox), almost immediately contradicted by Niels Bohr, concerned the interpretation of quantum mechanics.
The eighth afterlife realm is ruled by Uranus and develops psychic ability. The ninth afterlife realm is symbolized by Pluto, the astrological realm of the unconscious. This afterlife realm is a transient place where souls can choose to travel to other realms or other solar systems, it is the souls liberation into eternity, and is the realm that opens the doorway from our solar system into the cosmos. Mainstream Spiritualists postulate a series of seven realms that are not unlike Edgar Cayce's nine realms ruled by the planets.
Definitions of complexity often depend on the concept of a "system" – a set of parts or elements that have relationships among them differentiated from relationships with other elements outside the relational regime. Many definitions tend to postulate or assume that complexity expresses a condition of numerous elements in a system and numerous forms of relationships among the elements. However, what one sees as complex and what one sees as simple is relative and changes with time. Warren Weaver posited in 1948 two forms of complexity: disorganized complexity, and organized complexity.
Wittgenstein claims that the meaning of a word is based on how the word is understood within the language-game. A common summary of his argument is that meaning is use. According to the use theory of meaning, the words are not defined by reference to the objects they designate, nor by the mental representations one might associate with them, but by how they are used. For example, this means there is no need to postulate that there is something called good that exists independently of any good deed.
These include its focus on and reference to "factual aspects" (with the aforementioned scholars citing its emphasis on "cavalry and naval battles"), as well as its use of "autobiographical, meta-literary and panegyric elements". The scope and size of Ennius's poem was at the time of its penning also "unprecedented"; for instance, both Livius Andronicus's Odusia and Naevius's Bellum Punicum were substantially shorter.Goldberg & Manuwald (2018), pp. 10203. Sander M. Goldberg and Gesine Manuwald postulate that Ennius may have started writing a smaller historical poem that grew until it eventually comprised over a dozen books.
It turns out they were bombarded with "micromechanical devices", from which a wall of glass begins to grow and eventually assembles into a dome, an attempt to isolate the ship. The doubler that has joined the group proves to be uncommunicative, leading some of the crew to suggest that it has some sort of mental deficiency. The crew also begins to postulate that the "naked" doublers they have seen are the victims of genocide. Choosing to explore further, the crew activates "Defender", a large tank which they have managed to repair.
Nonetheless, Darwin's calculations could not resolve the mechanics required to trace the Moon backward to the surface of the Earth. In 1946, Reginald Aldworth Daly of Harvard University challenged Darwin's explanation, adjusting it to postulate that the creation of the Moon was caused by an impact rather than centrifugal forces. Little attention was paid to Professor Daly's challenge until a conference on satellites in 1974, during which the idea was reintroduced and later published and discussed in Icarus in 1975 by Drs. William K. Hartmann and Donald R. Davis.
Schultz published poetry in his early life, and several Latin texts on theology in 1787 and 1791. However, most of his literature was concerned with creation of mathematical texts, including the explanation of Immanuel Kant's new critical system (critical philosophy, transcendental idealism). Schultz wrote and successfully published several mathematical texts including Foundation of Pure Mathematics in 1790, a Brief System of Mathematics first published in 1797 with new editions in 1805 and 1806. However most of his interest was in the work concerning the Parallel Lines Postulate with papers published in 1780, 1784 and 1786.
This special role for measurements is problematic for the theory, as it contradicts Everett and DeWitt's goal of having a reductionist theory and undermines their criticism of the ill-defined measurement postulate of the Copenhagen interpretation. This is known today as the preferred basis problem. The preferred basis problem has been solved, according to Saunders and Wallace, among others, by incorporating decoherence in the many-worlds theory. In this approach, the preferred basis does not have to be postulated, but rather is identified as the basis stable under environmental decoherence.
Peres argued that the various many-worlds interpretations merely shift the arbitrariness or vagueness of the collapse postulate to the question of when "worlds" can be regarded as separate, and that no objective criterion for that separation can actually be formulated. Some consider MWI unfalsifiable and hence unscientific because the multiple parallel universes are non-communicating, in the sense that no information can be passed between them. Others claim MWI is directly testable. Victor J. Stenger remarked that Murray Gell-Mann's published work explicitly rejects the existence of simultaneous parallel universes.
Non-Euclidean geometry refers usually to geometrical spaces where the parallel postulate is false. They include elliptic geometry, where the sum of the angles of a triangle is more than 180°, and hyperbolic geometry, where this sum is less than 180°. Their introduction in the second half of 19th century, and the proof that their theory is consistent (if Euclidean geometry is not contradictory) is one of the paradoxes that are at the origin of the foundational crisis in mathematics of the beginning of 20th century, and motivated the systematization of axiomatic theories in mathematics.
Ritter's biography of Frederick, published in 1936, was designed as a challenge to Nazi claims that there was a continuity between Frederick and Hitler. Dorpalen says: "The book was indeed a very courageous indictment of Hitler's irrationalism and recklessness, his ideological fanaticism and insatiable lust for power". Throughout World War II, Hitler often compared himself to Frederick the Great. British-American historian Gordon A. Craig relates that to help legitimize Nazi rule Propaganda Minister Joseph Goebbels commissioned artists to render fanciful images of Frederick, Bismarck, and Hitler together to postulate a historical continuum between them.
Euclid's axioms seemed so intuitively obvious (with the possible exception of the parallel postulate) that any theorem proved from them was deemed true in an absolute, often metaphysical, sense. Today, however, many other self- consistent non-Euclidean geometries are known, the first ones having been discovered in the early 19th century. An implication of Albert Einstein's theory of general relativity is that physical space itself is not Euclidean, and Euclidean space is a good approximation for it only over short distances (relative to the strength of the gravitational field).Misner, Thorne, and Wheeler (1973), p.
Einstein's theory of special relativity involves a four-dimensional space-time, the Minkowski space, which is non-Euclidean. This shows that non-Euclidean geometries, which had been introduced a few years earlier for showing that the parallel postulate cannot be proved, are also useful for describing the physical world. However, the three-dimensional "space part" of the Minkowski space remains the space of Euclidean geometry. This is not the case with general relativity, for which the geometry of the space part of space-time is not Euclidean geometry.
In Peronist rhetoric, this event has come to be referred to as "The Renunciation", portraying Evita as having been a selfless woman in line with the Hispanic myth of marianismo. Most biographers postulate that Evita did not so much renounce her ambition as bow to pressure from her husband, the military, and the Argentine upper class, who preferred that she not enter the race. Perón's renunciation speech (in Spanish). Source: Radio Nacional. RTA. Argentina On 9 January 1950, Evita fainted in public and underwent surgery three days later.
According to The New York Times, the drama drew flack from the state of Massachusetts (where Sacco and Vanzetti were tried and executed) because it was thought to postulate that the condemned murderers were, in fact, wholly innocent. However, the resulting controversy actually did Lumet more good than harm, sending several prestigious film assignments his way. He began adapting classic plays for both film and television. In 1959, he directed Marlon Brando, Joanne Woodward and Anna Magnani in the feature film The Fugitive Kind, based on the Tennessee Williams play Orpheus Descending.
Over the past decade many scientists argued that the hierarchy problem is a specific application of Bayesian statistics. Studying renormalization in hierarchy problems is difficult, because such quantum corrections are usually power-law divergent, which means that the shortest-distance physics are most important. Because we do not know the precise details of the shortest-distance theory of physics, we cannot even address how this delicate cancellation between two large terms occurs. Therefore, researchers are led to postulate new physical phenomena that resolve hierarchy problems without fine tuning.
It is also the configuration corresponding to the maximum of a system's entropy for a given set of accessible microstates, in other words the macroscopic configuration in which the lack of information is maximal. As such, according to the second law of thermodynamics, it is the equilibrium configuration of an isolated system. Boltzmann's entropy is the expression of entropy at thermodynamic equilibrium in the microcanonical ensemble. This postulate, which is known as Boltzmann's principle, may be regarded as the foundation of statistical mechanics, which describes thermodynamic systems using the statistical behavior of its constituents.
Parallelogram ABCD To prove that the diagonals of a parallelogram bisect each other, we will use congruent triangles: :\angle ABE \cong \angle CDE (alternate interior angles are equal in measure) :\angle BAE \cong \angle DCE (alternate interior angles are equal in measure). (since these are angles that a transversal makes with parallel lines AB and DC). Also, side AB is equal in length to side DC, since opposite sides of a parallelogram are equal in length. Therefore, triangles ABE and CDE are congruent (ASA postulate, two corresponding angles and the included side).
Population (est.) 10,000 BC – 2000 AD In the I=PAT equation, the variable P represents the population of an area, such as the world. Since the rise of industrial societies, human population has been increasing exponentially. This has caused Thomas Malthus, Paul Ehrlich and many others to postulate that this growth would continue until checked by widespread hunger and famine (see Malthusian growth model). The United Nations project that world population will increase from 7.7 billion today (2019) to 9.8 billion in 2050 and about 11.2 billion in 2100.
DNAJC30 is expressed in many tissues, including the brain, heart, kidney, liver, lung, spleen, stomach, and testis, though no transcripts were found in colon, small intestine, and muscle. This protein has been found to localize to the cytosol and mitochondria of cells. Though its exact biological function has yet to be elucidated, the centromeric location of DNAJC30 on the chromosome has led Merla et al. to postulate that it may contribute to functions such as subtle defects in cognition, transient hypercalcemia, and gastrointestinal problems experienced by Williams Beuren syndrome patients.
And using the electromagnetic momentum, he could explain the negative result of the Trouton–Noble experiment, in which a charged parallel-plate capacitor moving through the aether should orient itself perpendicular to the motion. Also the experiments of Rayleigh and Brace could be explained. Another important step was the postulate that the Lorentz transformation has to be valid for non- electrical forces as well.Janssen (1995), Ch. 3.3, 3.4 At the same time, when Lorentz worked out his theory, Wien (1903) recognized an important consequence of the velocity dependence of mass.
He introduced a non-electrical binding force (the so-called "Poincaré stresses") to ensure the stability of the electrons and to explain length contraction. He also sketched a Lorentz- invariant model of gravitation (including gravitational waves) by extending the validity of Lorentz-invariance to non-electrical forces.Miller (1981), 79–86Katzir (2005), 280–288 Eventually Poincaré (independently of Einstein) finished a substantially extended work of his June paper (the so-called "Palermo paper", received July 23, printed December 14, published January 1906 ). He spoke literally of "the postulate of relativity".
Later, Nernst's theorem (or Nernst's postulate), which is now known as the third law, was formulated by Walther Nernst over the period 1906-12. While the numbering of the laws is universal today, various textbooks throughout the 20th century have numbered the laws differently. In some fields, the second law was considered to deal with the efficiency of heat engines only, whereas what was called the third law dealt with entropy increases. Gradually, this resolved itself and a zeroth law was later added to allow for a self-consistent definition of temperature.
Cottier was critical of anonymous Christianity, saying that a theological system that absorbs all realities into Christ ends by turning Christ into a kind of metaphysical postulate of the affirmation of human values, which makes the Church incapable of engaging in serious dialogue, even on the level of human rights. Then, saying that everybody is already of Christ, whether they know it or not, can make the mission futile.If everything is grace, then grace is no more» Cottier said that the use of condoms may be morally licit in the context of fighting AIDS.
The theorems of Ibn al-Haytham, Khayyam and al-Tusi on quadrilaterals, including the Lambert quadrilateral and Saccheri quadrilateral, were "the first few theorems of the hyperbolic and the elliptic geometries". These theorems along with their alternative postulates, such as Playfair's axiom, played an important role in the later development of non- Euclidean geometry. These early attempts at challenging the fifth postulate had a considerable influence on its development among later European geometers, including Witelo, Levi ben Gerson, Alfonso, John Wallis and Saccheri.Boris A. Rosenfeld & Adolf P. Youschkevitch, "Geometry", p.
235-236 In tandem, Nicolăescu- Plopșor took personal part in reassessing the Pleistocene and Neanderthal presence in Romania. His Bordul Mare expedition uncovered fossilized Neanderthal and game remains, as well as a characteristic hearth. With his reassessment of earlier theories came the assessment that the supposed australopithecine in the Tetoiu area used stones collected from great distances in carving out the carcasses of large animals—leading Nicolăescu- Plopșor to postulate that Tetoiu was a link between the australopithecine sites on three continents, evidencing "the oldest stages in the process of conscious work."Doboș, p.
In October 1871 Roudaut left for the Postulate of Vans, at the age of twenty four. On 26 January 1874 she arrived in Algeria where she was assigned to the orphanage of St Charles at Kouba, Algeria, now a suburb of Algiers. She received the habit on 23 June 1872 as Sister Marie-Salomé, and made her first profession on 6 July 1873. On 23 January 1874 she was sent to the mission of St Cyprien of the Attafs, a village for orphans whom the church had raised to adulthood.
"Comparative Numic Ethnobiology". University of Pittsburgh PhD dissertation. By about 1000, there were hunters and gatherers in the Great Basin of Uto- Aztecan ethnicity that are believed to have been the ancestors of the Indigenous tribes of the Great Basin, including the Ute, Apache, Shoshone, Hopi, Paiute, and Chemehuevi peoples. Some ethnologists postulate that the Southern Numic speakers, the Ute and Southern Paiute, left the Numic homeland first, based on language changes, and that the Central and then the Western subgroups spread out toward the east and north, sometime later.
247–261 "I have not established the principle of relativity as rigorously and universally true. Poincaré, on the other hand, has obtained a perfect invariance of the electro-magnetic equations, and he has formulated 'the postulate of relativity', terms which he was the first to employ."French original: je n'ai pas établi le principe de relativité comme rigoureusement et universellement vrai. Poincaré, au contraire, a obtenu une invariance parfaite des équations de l’électrodynamique, et il a formule le « postulat de relativité », termes qu’il a été le premier a employer.
Moreover, it differs from other approaches in that it does not postulate an independent level of syntactic structure over words. DS emerged in the late 1990s and early 2000s through the work of prominent figures such as Ruth Kempson, Ronnie Cann, Wilfried Meyer-Viol and Dov Gabbay. The first monograph- length work in the framework was released in 2001 under the title Dynamic Syntax: the flow of understanding. It was embedded in wider trends in linguistic thinking of the 20th century, especially in syntax, semantics, pragmatics and phonology.
The Laplacian differential operator, widely used in mathematics, is also named after him. He restated and developed the nebular hypothesis of the origin of the Solar System and was one of the first scientists to postulate the existence of black holes and the notion of gravitational collapse. Laplace is remembered as one of the greatest scientists of all time. Sometimes referred to as the French Newton or Newton of France, he has been described as possessing a phenomenal natural mathematical faculty superior to that of any of his contemporaries.
In 1975, Stephen Hawking published a calculation which suggested that black holes are not completely black but emit a dim radiation due to quantum effects near the event horizon. This work extended previous results of Jacob Bekenstein who had suggested that black holes have a well defined entropy.Bekenstein 1973 At first, Hawking's result appeared to contradict one of the main postulates of quantum mechanics, namely the unitarity of time evolution. Intuitively, the unitarity postulate says that quantum mechanical systems do not destroy information as they evolve from one state to another.
Humphreys' book Starlight and Time presents his alternative to the Big Bang in an attempt to solve what young Earth creationists call the Distant Starlight Problem. Its thesis is that the Earth and universe are about six thousand years old when measured in Earth's reference frame, whereas the outer edge of an expanding and rotating 3-dimensional universe is billions of years old (as measured from its reference frame). It proposes, using the principles of relativity, to postulate that time ticked at different rates during the universe's origin.Starlight and Time, Russell Humphreys, Chapter 2, p.
The only states considered in equilibrium thermodynamics are equilibrium states. Classical thermodynamics includes (a) equilibrium thermodynamics; (b) systems considered in terms of cyclic sequences of processes rather than of states of the system; such were historically important in the conceptual development of the subject. Systems considered in terms of continuously persisting processes described by steady flows are important in engineering. The very existence of thermodynamic equilibrium, defining states of thermodynamic systems, is the essential, characteristic, and most fundamental postulate of thermodynamics, though it is only rarely cited as a numbered law.
In the attempt to justify the postulate of entropy increase in the second law of thermodynamics, Boltzmann's H-theorem used equations, which assumed that a system (for example, a gas) was isolated. That is all the mechanical degrees of freedom could be specified, treating the walls simply as mirror boundary conditions. This inevitably led to Loschmidt's paradox. However, if the stochastic behavior of the molecules in actual walls is considered, along with the randomizing effect of the ambient, background thermal radiation, Boltzmann's assumption of molecular chaos can be justified.
The reason that systems can not proceed toward some kind of disintegration is that such a pattern has no mechanism of maintaining itself. As soon as it does the system fits the definition of an entity. Odum then went on to explore the consequence of applying such a view (1950, p.9): If this postulate is applied to all of nature, the resulting proposition is that nature is as a whole in a steady state or is in the most stable form possible and constitutes one big entity.
There is no retribution, judgment or reward involved but a natural consequences of the choices in life made either knowingly or unknowingly. Hence, whatever suffering or pleasure that a soul may be experiencing in its present life is on account of choices that it has made in the past.Kuhn, Hermann (2001) p.15 As a result of this doctrine, Jainism attributes supreme importance to pure thinking and moral behavior.Rankin, Aidan (2006) p.67 The Jain texts postulate four gatis, that is states-of-existence or birth-categories, within which the soul transmigrates.
Starting with the ten- or eleven-dimensional spacetime of string or M-theory, physicists postulate a shape for the extra dimensions. By choosing this shape appropriately, they can construct models roughly similar to the standard model of particle physics, together with additional undiscovered particles,Candelas et al. 1985 usually supersymmetric partners to analogues of known particles. One popular way of deriving realistic physics from string theory is to start with the heterotic theory in ten dimensions and assume that the six extra dimensions of spacetime are shaped like a six- dimensional Calabi–Yau manifold.
A similar scheme had been independently proposed by Yuval Ne'eman, and is now explained by the quark model. Gell-Mann referred to the scheme as the eightfold way, because of the octets of particles in the classification (the term is a reference to the Eightfold Path of Buddhism). Gell-Mann, along with Maurice Lévy, developed the sigma model of pions, which describes low-energy pion interactions. In 1964, Gell-Mann and, independently, George Zweig went on to postulate the existence of quarks, particles of which the hadrons of this scheme are composed.
He soon became one of the main contenders for the PRI candidacy for governor of Quintana Roo, its main contender and head in the polls was Carlos Joaquín González, however, on March 24, 2010 he asked and obtained a leave as member of the Chamber of Deputies. On March 26 he was fue postulate as candidate of the unity to the state government. Roberto Borge was elected in the electoral process of July 4 and received the appointment as elect- governor on July 11. He took office on April 5, 2011.
Ernst Mach and the logical positivists rejected John Dalton's atomic theory until the reality of atoms was more evident in Brownian motion, as shown by Albert Einstein. In the same way, postulating the aether is more complex than transmission of light through a vacuum. At the time, however, all known waves propagated through a physical medium, and it seemed simpler to postulate the existence of a medium than to theorize about wave propagation without a medium. Likewise, Newton's idea of light particles seemed simpler than Christiaan Huygens's idea of waves, so many favored it.
The black-body problem was revisited in 1905, when Rayleigh and Jeans (on the one hand) and Einstein (on the other hand) independently proved that classical electromagnetism could never account for the observed spectrum. These proofs are commonly known as the "ultraviolet catastrophe", a name coined by Paul Ehrenfest in 1911. They contributed greatly (along with Einstein's work on the photoelectric effect) in convincing physicists that Planck's postulate of quantized energy levels was more than a mere mathematical formalism. The first Solvay Conference in 1911 was devoted to "the theory of radiation and quanta".
Leviticus 17–22, 1515–1520 Victor P. Hamilton,Victor P. Hamilton. The Book of Genesis Chapters 18–50 and Calum CarmichaelCarmichael. Legend and Incest postulate that the Levitical laws could not have been developed the way they were, without controversial issues surrounding the patriarchs of Israel, especially regarding incest. Carmichael even attributes the entire formulation of the Levitical laws to the lives of the founding fathers of the nation, including the righteous Lot (together with Abraham, Jacob, Judah, Moses, and David), who were outstanding figures in Israelite tradition.
The sum of the angles of a hyperbolic triangle is less than 180°. The relation between angular defect and the triangle's area was first proven by Johann Heinrich Lambert. One can easily see how hyperbolic geometry breaks Playfair's axiom, Proclus' axiom (the parallelism, defined as non-intersection, is intransitive in an hyperbolic plane), the equidistance postulate (the points on one side of, and equidistant from, a given line do not form a line), and Pythagoras' theorem. A circleDefined as the set of points at the fixed distance from its centre.
Strahler, A.N. 1987. Science and Earth History- The Evolution/Creation Controversy, Prometheus Books, Amherst, New York, USA. p. 194: “Under the updated statement of a useful principle of uniformitarianism it boils down essentially to affirmation of the validity of universal scientific laws through time and space, coupled with a rejection of supernatural causes.” p. 62: “In cosmology, the study of the structure and evolution of the universe, it is assumed that the laws of physics are similar throughout the entire universe.” Though an unprovable postulate that cannot be verified using the scientific method,Rosenberg, Alex.
Research Notes of the AAS, Volume 1, No. 1, p. 50 (Dec 2017). Although both chipping by collisions and frictional abrasion gradually eliminates balance points, still, shapes stop short of becoming a Gömböc; the latter, having N=2 balance points, appears as an unattainable end point of this natural process. The likewise invisible starting point appears to be the cube with N=26 balance points, confirming a postulate by Plato who identified the four classical elements and the cosmos with the five Platonic solids, in particular, he identified the element Earth with the cube.
Agrarian conservatism in Germany was a type of conservatism that began to wane in popularity prior to the rise of the Nazi Party. Following the Aufklärung, German Conservatives rejected the newly-emergent habit of constantly questioning the status quo and never finding satisfaction in the present moment. Instead, these conservatives ardently insisted that this new, “enlightened” mode of thought was dominated by perverse skepticism, immorality, and the undermining of authority. By the late nineteenth century, the conservative ideology had fragmented as thinkers began to postulate their own understandings of the world.
Therefore, we admit the fact that our knowledge of the world is incomplete. The open-world assumption is closely related to the monotonic nature of first-order logic: adding new information never falsifies a previous conclusion. Namely, if we subsequently learn that Paul is also a citizen of France, this does not change any earlier positive or negative conclusions. The language of logic programs with strong negation allows us to postulate the closed-world assumption for some statements and leave the other statements in the realm of the open-world assumption.
51 MosGIRD worked on the development of space research, liquid-propellant rockets, rocket design as it pertained to aircraft, and the construction of a supersonic wind tunnel (used for the aerodynamic testing of the aircraft that they developed), whereas LenGIRD developed solid-fuel rockets used for photographing the upper atmosphere, carrying flares, and atmospheric sounding.Stoiko, pp. 51–53 Early pioneers in the field began to postulate that liquid fuels were more powerful than solid fuels. Some of the early fuels used by these scientists were oxygen, alcohol, methane, hydrogen, or combinations of them.
Stone's return from space, accompanied by meteorite-like debris, may be seen as a hint that elements essential to the development of life on Earth may have come from outer space in the form of meteorites. The film also suggests themes of humanity's ubiquitous strategy of existential resilience; that, across cultures, individuals must postulate meaning, beyond material existence, wherever none can be perceived. Some commentators have noted possible religious themes in the film. For instance, Robert Barron in The Catholic Register summarizes the tension between Gravitys technology and religious symbolism.
Two professors at the Wharton School at the University of Pennsylvania also found that uplifting stories were more likely to be shared on the New York Times' web site than disheartening ones. Others postulate that sharing is driven by ego in order to build up an online persona for oneself. Chartbeat, a company that measures online traffic, compiled data comparing the amount of time spent reading an article and the number of times it was shared and found that people often post articles on Twitter they haven't even read.
Eymerich then extrapolates on this postulate to demonstrate that any agreement with a demon is a heresy. Eymerich was among the first to condemn all forms of demonic conjuration as heresy. Previously, the common belief had been that even a saint might make a demonic pact as exemplified by the story of Saint Theophilus, who made a pact with the devil to gain an ecclesiastical position. In addition to describing common magical practices, Eymerich also described means of extracting a confession which included primitive psychological manipulation as well as outright torture.
I–2 By modelling matter as collections of hard spheres, it is possible to describe the kinetic theory of gases, upon which classical thermodynamics is based. Thermodynamics studies the effects of changes in temperature, pressure, and volume on physical systems on the macroscopic scale, and the transfer of energy as heat. Historically, thermodynamics developed out of the desire to increase the efficiency of early steam engines. The starting point for most thermodynamic considerations is the laws of thermodynamics, which postulate that energy can be exchanged between physical systems as heat or work.
There is considerable debate about whether the Khazzoom-Brookes Postulate is correct, and of the relevance of the Jevons paradox to energy conservation policy. Most governments, environmentalists and NGOs pursue policies that improve efficiency, holding that these policies will lower resource consumption and reduce environmental problems. Others, including many environmental economists, doubt this 'efficiency strategy' towards sustainability, and worry that efficiency gains may in fact lead to higher production and consumption. They hold that for resource use to fall, efficiency gains should be coupled with other policies that limit resource use.
For this reason many historians such as Eugène Tisserant, Tfinkdji, and Fiey postulate the existence of one Shimun (VIII) who reigned in Alqosh from 1552 to 1558. Becchetti himself says that in reality the designated successor was neither an 8-year-old nor was he dead. More recent scholars such as Habbi and Lampar, suggest that Shimun VII did not die in 1551 but reigned till 1558, and that Sulaqa had lied to the pope. On February 20, 1553, Yohannan Sulaqa made a profession of faith in front of the Pope.
They are round or elliptic/ cup- shaped coins of the Achaemenid weight standard, struck with one, two or several punches. They usually display a sort of arrow symbol on the obverse, and circular geometric symbols on the reverse. Similar coins have also been found in the Shaikhan Dehri hoard in Pushkalavati in the center of the Gandhara area, but not in Taxila. Their dispersal in Kabul and Pushakalavati led Bopearachchi to postulate that they were manufactured locally, while the region was under Achaemenid protection, during the 5th century BCE.

Four years later, Sava managed somehow to escape and arrive in Moscow. There, he told the Russian authorities that his vocation before being captured, was masterstvo— meaning creative, artistic work. From the document we could freely postulate that he worked as an assistant to the painters employed by Posolsky Prikaz and the Kremlin Armoury for the next six years (in fact, from 1688 to 1694). It is evident from Krabulević's icons produced for Orahovica Monastery that he acquired his knowledge and honed his skill with the best masters in Imperial Russia of that period.
This cycle, which is controlled by the autonomic nervous system, has a mean duration of two and a half hours. He further observed and documented that the turbinates in the dependent nasal fossa fill when the patient is in the lateral decubitus (lying down on your side) position. Some postulate that this alternating positional obstruction has the purpose of causing a person to turn from one side to the other while sleeping in order to prevent bedsores. Others note that the asymmetric airflow may have some benefit to overall olfactory sensitivity.
As a metaphysical position, solipsism goes further to the conclusion that the world and other minds do not exist. Solipsism is the only epistemological position that, by its own postulate, is both irrefutable and yet indefensible in the same manner. Although the number of individuals sincerely espousing solipsism has been small, it is not uncommon for one philosopher to accuse another's arguments of entailing solipsism as an unwanted consequence, in a kind of reductio ad absurdum. In the history of philosophy, solipsism has served as a skeptical hypothesis.
A paper published in 1938 by Albert Einstein, Leopold Infeld and Banesh Hoffmann showed that if elementary particles are treated as singularities in spacetime, it is unnecessary to postulate geodesic motion as part of general relativity. The electron may be treated as such a singularity. If one ignores the electron's angular momentum and charge, as well as the effects of quantum mechanics, one can treat the electron as a black hole and attempt to compute its radius. The Schwarzschild radius of a mass is the radius of the event horizon for a non-rotating, uncharged black hole of that mass.
Krivo and Kaufman also postulate that the types of mortgage loans minorities obtain contributes to the differences in home equity. FHA and VA loans make up one- third or more of primary loans for African Americans and Hispanics, while only 18% for White Americans and 16% for Asians. These loans require lower down payments and cost more than conventional mortgages, which contributes to a slower accumulation of equity. Asians and Hispanics have lower net equity on houses partly because they are youngest on average, but age has only a small effect on the Black-White gap in home equity.
Okishio agreed with Roy F. Harrod that the market economy was not only from a static perspective but also from a dynamic perspectives. Harrod arguments are necessarily clear, however, about investment decision making. Okishio wrote many papers to clarify the Harrod instability logic and showed that instability is an inherent characteristic in the accumulation process of the capitalist economy. Problems examined are (A) to make clear capitalists’ investment decision of Harrod and (B) to investigate the instability postulate taking into consideration other possibilities like substitutive technical changes, changes in saving ratio, and movements in relative prices.
Postdiction involves explanation after the fact. In skepticism, it is considered an effect of hindsight bias that explains claimed predictions of significant events such as plane crashes and natural disasters. In religious contexts, theologians frequently refer to postdiction using the Latin term vaticinium ex eventu (foretelling after the event). Through this term, skeptics postulate that many biblical prophecies (and similar prophecies in other religions) appearing to have come true may have been written after the events supposedly predicted, or that the text or interpretation may have been modified after the event to fit the facts as they occurred.
He proposed to accomplish this by carefully nursing her resources, and in the meantime securing and enriching her by alliances, which would bring in large subsidies while imposing a minimum of obligations. Such a conditional and tentative policy, in a period of universal tension and turmoil, was most difficult; but Griffenfeld did not regard it as impossible. The first demand of such a policy was peace, especially peace with Denmark's most dangerous neighbour, Sweden. The second postulate was a sound financial basis, which he expected the wealth of France to supply in the shape of subsidies to be spent on armaments.
In this paper, Pasinetti showed that the concept of the rate of return on capital, introduced by Irving Fisher, and resumed and used by Solow in 1967 as a means of rescuing the neoclassical capital theory, had no economic significance. Whichever of the two definitions given by Fisher on the rate of return was accepted, one of them was an accounting expression Harcourt, G. and Laing N. (eds.) [1977], p. 266. and in the other (in order to say anything on interest) would entail accepting a rather unobtrusive postulate in order to avoid the problem of reswitching.
Nogai Khan, half a century later, married a daughter of the Byzantine emperor and gave his own daughter in marriage to a Rus' prince, Theodor the Black. Some modern revisionist Russian historians (most notably the Soviet era historian and "Neo-Eurasianist" ideologist Lev Gumilev) even postulate that there was no invasion at all. According to them, the Rus' princes concluded a defensive alliance with the Horde in order to repel attacks of the fanatical Teutonic Knights, which posed a much greater threat to the Rus' religion and culture. These points represent the bright side of Tartar rule.
There are different ways to set up the notion of number in metaphysics theories. Platonist theories postulate number as a fundamental category itself. Others consider it to be a property of an entity called a "group" comprising other entities; or to be a relation held between several groups of entities, such as "the number four is the set of all sets of four things". Many of the debates around universals are applied to the study of number, and are of particular importance due to its status as a foundation for the philosophy of mathematics and for mathematics itself.
In his own words: > "... part of the carbonate of lime is replaced by carbonate of magnesia, so > as to form in the new species a compound of one atom each. How this change > was brought about, is a difficult question to resolve, though the fact > cannot be doubted, as we have in the specimen described a demonstration of > it, approaching in certainty almost to ocular evidence".Haidinger, 1831, p. > 108) To geologists Haidinger is known especially for his postulate of the "dolomitization" reaction that would change calcium carbonate into dolomite at low temperatures (below 100 degrees Celsius).
By making the cell membrane more impermeable, hypothermia helps prevent the cascade of reactions set off by oxygen deprivation. Even moderate dips in temperature strengthen the cellular membrane, helping to minimize any disruption to the cellular environment. It is by moderating the disruption of homeostasis caused by a blockage of blood flow that many now postulate, results in hypothermia's ability to minimize the trauma resultant from ischemic injuries. Targeted temperature management may also help to reduce reperfusion injury, damage caused by oxidative stress when the blood supply is restored to a tissue after a period of ischemia.
Charles Spearman was the first psychologist to discuss common factor analysis and did so in his 1904 paper. It provided few details about his methods and was concerned with single-factor models. He discovered that school children's scores on a wide variety of seemingly unrelated subjects were positively correlated, which led him to postulate that a single general mental ability, or g, underlies and shapes human cognitive performance. The initial development of common factor analysis with multiple factors was given by Louis Thurstone in two papers in the early 1930s, summarized in his 1935 book, The Vector of Mind.
Domenici and colleagues (2014) postulate that these fin extensions enhance the accuracy of tapping and slashing. The sail can reduce yaw rotation by counteracting the lateral force in the direction opposite to the slash. This means that prey is less likely to recognize the massive trunk as being part of an approaching predator (Marras and colleagues, 2015; Webb & Weihs 2015). Spinosaurus exhibited the anatomical features required to combine all three hunting strategies: a sail for herding prey more efficiently, as well as flexible tail and neck to slap the water for stunning, injuring or killing prey.
He earned his undergraduate degree in Economics from Università degli Studi of Turin in 1982 and his PhD in Economics from Yale University in 1989 with a dissertation on stock price volatility. After being a Lecturer in Economics at the University of Turin, he has become associate Professor at Bocconi University in 1998 and then Full Professor in 2000. During the 1990s, he studied economic growth and sustainable development. In his studies, where he analyzed some of the principles of political philosophy stated by John Rawls, Beltratti addressed the postulate that an economy is sustainable when it does not compromise future generations' wealth.
In the mid to late 1990s, a global response to the changes in biblical criticism began to coalesce as "Postcolonial biblical criticism". Fernando F. Segovia and Stephen D. Moore postulate that it emerged from "liberation hermeneutics, or extra-biblical Postcolonial studies, or even from historical biblical criticism, or from all three sources at once". It has a focus on the indigenous and local with an eye toward recovering those aspects of culture that Colonialism had erased or suppressed. The Postcolonial view is rooted in a consciousness of the geopolitical situation for all people, and is "transhistorical and transcultural".
Events in Christian Europe, such as the Galileo affair, that were associated with the Scientific Revolution and the Age of Enlightenment led scholars such as John William Draper to postulate a conflict thesis, holding that religion and science have been in conflict methodologically, factually and politically throughout history. This thesis is held by several scientists like Richard Dawkins and Lawrence Krauss. While the conflict thesis remains popular in antitheistic circles, it has lost favor among most contemporary historians of science, and the majority of scientists in elite universities in the U.S. do not hold a conflict view.
The Boolean algebras we have seen so far have all been concrete, consisting of bit vectors or equivalently of subsets of some set. Such a Boolean algebra consists of a set and operations on that set which can be shown to satisfy the laws of Boolean algebra. Instead of showing that the Boolean laws are satisfied, we can instead postulate a set X, two binary operations on X, and one unary operation, and require that those operations satisfy the laws of Boolean algebra. The elements of X need not be bit vectors or subsets but can be anything at all.
This problem was known (in a different guise) to Khayyam, Saccheri and Lambert and was the basis for their rejecting what was known as the "obtuse angle case". In order to obtain a consistent set of axioms which includes this axiom about having no parallel lines, some of the other axioms must be tweaked. The adjustments to be made depend upon the axiom system being used. Amongst others these tweaks will have the effect of modifying Euclid's second postulate from the statement that line segments can be extended indefinitely to the statement that lines are unbounded.
The postulate was a response to the debate among sociologists – mainly between Kenneth J. Gergen and Barry R. Schlenker – revolving around the meaning of sociological research. Whilst Schlenker appeared to maintain the position, that context only superficially influenced social behavior, Gergen appeared to maintain that context penetrated everything in social behavior, rendering observations as specific to the very situation observed. Thus, simplifying the discussion, the observation of social behavior would be no more than collecting historical data, since context would never be the same and the results would remain unique. In fact, sociology would be some specialized kind of historical research.
An inductive proof for arithmetic sequences was introduced in the Al-Fakhri (1000) by Al-Karaji, who used it to prove the binomial theorem and properties of Pascal's triangle. Alhazen also developed the method of proof by contradiction, as the first attempt at proving the Euclidean parallel postulate. Modern proof theory treats proofs as inductively defined data structures, not requiring an assumption that axioms are "true" in any sense. This allows parallel mathematical theories as formal models of a given intuitive concept, based on alternate sets of axioms, for example Axiomatic set theory and Non-Euclidean geometry.
A statement that is neither provable nor disprovable from a set of axioms is called undecidable (from those axioms). One example is the parallel postulate, which is neither provable nor refutable from the remaining axioms of Euclidean geometry. Mathematicians have shown there are many statements that are neither provable nor disprovable in Zermelo–Fraenkel set theory with the axiom of choice (ZFC), the standard system of set theory in mathematics (assuming that ZFC is consistent); see list of statements undecidable in ZFC. Gödel's (first) incompleteness theorem shows that many axiom systems of mathematical interest will have undecidable statements.
Unable to communicate or negotiate with the Bugs, the Alliance realises that the war has become a fight for the survival of their respective species and invoke Directive 18, last used against the Rigelians, and embark upon a war of species extermination. Hope arrives when the Alliance infers that, due to differences in construction methods, they can be faced by no more than five Bug Home systems. They also postulate that the massive Bug fleets are, in fact, the end result of years of military build-up. The reason for this seemingly unnecessary military reserve remains unknown.
The system classifications proceeded from the postulate that the whole is not a sum of its parts, but rather, a system of higher organization. This classification is frequently based on the laws of the functioning Universe. The properties of this classification are: strictness (everyone belongs to one and only one class and remains in it for the whole life), quantity of classes determined by laws of the Universe, and the organization of the psyche as a part of a more general system of a functioning Universe. Examples: Astrological (Egypt, Babylon, Greece, the Classical antiquity), astro-musical system of types (India).
A – Active site B – Allosteric site C – Substrate D – Inhibitor E – Enzyme This is a diagram of allosteric regulation of an enzyme. Many allosteric effects can be explained by the concerted MWC model put forth by Monod, Wyman, and Changeux, or by the sequential model described by Koshland, Nemethy, and Filmer. Both postulate that protein subunits exist in one of two conformations, tensed (T) or relaxed (R), and that relaxed subunits bind substrate more readily than those in the tense state. The two models differ most in their assumptions about subunit interaction and the preexistence of both states.
In the first, which does not mention Ahlquist, dichloroisoprenaline blocked ″certain adrenergic inhibitory receptor sites″; but in the second the results ″support the postulate of Ahlquist (1948) that the adrenotropic inhibitory receptors and the cardiac chronotropic and inotropic adrenergic receptors are functionally identical, i.e., that both are beta type receptors. … It is suggested that this terminology be extended to the realm of adrenergic blocking drugs, e.g., that blocking drugs be designated according to the receptor for which they have the greatest affinity, as either alpha or beta adrenergic blocking drugs.” Dichloroisoprenaline was the first beta blocker; it retains some intrinsic activity.
Each observer presides over his or her own space-time framework or coordinate system. There being no absolute frame of reference, all observers of given events make different but equally valid (and reconcilable) measurements. What remains absolute is stated in Einstein's relativity postulate: "The basic laws of physics are identical for two observers who have a constant relative velocity with respect to each other." Special relativity had a profound effect on physics: started as a rethinking of the theory of electromagnetism, it found a new symmetry law of nature, now called Poincaré symmetry, that replaced the old Galilean symmetry.
266 in the 1963 edition Anthropologists circa 1940 assumed that religion was in complete continuity with magical thinking, and that it is a cultural product. The complete continuity between magic and religion has been a postulate of modern anthropology at least since early 1930s. The perspective of modern anthropology towards religion is the projection idea, a methodological approach which assumes that every religion is created by the human community that worships it, that "creative activity ascribed to God is projected from man". In 1841, Ludwig Feuerbach was the first to employ this concept as the basis for a systematic critique of religion.
The formalism of process matrices starts from the observation that, given the structure of quantum states, the set of feasible quantum operations follows from positivity considerations. Namely, for any linear map from states to probabilities one can find a physical system where this map corresponds to a physical measurement. Likewise, any linear transformation that maps composite states to states corresponds to a valid operation in some physical system. In view of this trend, it is reasonable to postulate that any high-order map from quantum instruments (namely, measurement processes) to probabilities should also be physically realizable.
The cause and purpose of these arousals is still not clear; the question of why hibernators may return periodically to normal body temperatures has plagued researchers for decades, and while there is still no clear-cut explanation, there are multiple hypotheses on the topic. One favored hypothesis is that hibernators build a "sleep debt" during hibernation, and so must occasionally warm up to sleep. This has been supported by evidence in the Arctic ground squirrel. Other theories postulate that brief periods of high body temperature during hibernation allow the animal to restore its available energy sources or to initiate an immune response.
Prosecutors questioned why Lozano did not intervene in a more determined way so that the Communist Party eliminated from its ideology the concept of combining all forms of struggle to gain power, a postulate that the rebel movement also shared. Lozano denied his links to FARC and said he never recommended kidnappings or terrorist acts. Lozano ran for Senate in 2014 for the Green Alliance ticket and his participation in the rapprochement of the Government with the guerrillas of the FARC and the ELN was highlighted. He died of stomach cancer in Bogota on 23 May 2018.
Simon B. Kochen and Ernst Specker, and separately John Bell, constructed proofs any realistic hidden-variable theory able to explain the phenomenology of quantum mechanics is contextual for systems of Hilbert space dimension three and greater. The Kochen–Specker theorem proves that realistic noncontextual hidden variable theories cannot reproduce the empirical predictions of quantum mechanics. Such a theory would suppose the following. # All quantum-mechanical observables may be simultaneously assigned definite values (this is the realism postulate, which is false in standard quantum mechanics, since there are observables which are undefinite in every given quantum state).
This well-known physical constant is commonly referred to as the speed of light. The postulate of the constancy of the speed of light in all inertial reference frames lies at the heart of special relativity and has given rise to a popular notion that the "speed of light is always the same". However, in many situations light is more than a disturbance in the electromagnetic field. Light traveling within a medium is no longer a disturbance solely of the electromagnetic field, but rather a disturbance of the field and the positions and velocities of the charged particles (electrons) within the material.
Gwen collates a chart of the missing people and her colleague Toshiko (Naoko Mori) discovers that all the disappearances occurred during negative spikes of activity from the Cardiff space-time rift. The two women postulate the implications of this: that the rift can take people away and discard them elsewhere. Gwen confronts her boss Jack Harkness (John Barrowman) with her research but he informs her that nothing can be done and orders her to stop the investigation. Gwen becomes consumed with the issue of the missing individuals and this takes its toll on her relationship with her husband Rhys (Kai Owen).
Although Huntington's research was mainly in pure mathematics, he valued teaching mathematics to engineering students. He advocated mechanical calculators and had one in his office. He had an interest in statistics, unusual for the time, and worked on statistical problems for the USA military during World War I. Huntington's primary research interest was the foundations of mathematics. He was one of the "American postulate theorists" (according to Michael Scanlan, the expression is due to John Corcoran), American mathematicians active early in the 20th century (including E. H. Moore and Oswald Veblen) who proposed axiom sets for a variety of mathematical systems.
The hysteretic Bouc–Wen model has received some criticism regarding its ability to accurately describe the phenomenon of hysteresis in materials. Ikhouane and Rodellar (2005) give some insight regarding the behavior of the Bouc–Wen model and provide evidence that the response of the Bouc–Wen model under periodic input is asymptotically periodic. Charalampakis and Koumousis (2009) propose a modification on the Bouc–Wen model to eliminate displacement drift, force relaxation and nonclosure of hysteretic loops when the material is subjected to short unloading reloading paths resulting to local violation of Drucker's or Ilyushin's postulate of plasticity.
The upper parts, including the shoulders and upper back, are russet to reddish-buff to brownish, and are sometimes "frosted" with silvery gray white hairs. The presence or absence of a dorsal stripe and silvery hair tips appear to be a seasonal variation and have led some to postulate the existence of an additional species, N. intermedius, although DNA analysis has since confirmed this to be an adult version of the pygmy slow loris. The pygmy slow loris has buffy flanks, paler than the back. The upper sides of the arms are ochraceous, and have silvery hairs mingled with the darker ones.
The first known use of the name "America" dates back to 1507, when it appeared on a world map created by the German cartographer Martin Waldseemüller. It comes from the given name of Italian explorer Amerigo Vespucci, who was the first to postulate that the West Indies did not represent Asia's eastern limit, but part of a previously unknown landmass. The full name "United States of America" dates to the Revolutionary War. The second draft of the Articles of Confederation, prepared by John Dickinson, and Thomas Jefferson's original rough draft of the Declaration of Independence both included the name.
Emission theory, also called emitter theory or ballistic theory of light, was a competing theory for the special theory of relativity, explaining the results of the Michelson–Morley experiment of 1887. Emission theories obey the principle of relativity by having no preferred frame for light transmission, but say that light is emitted at speed "c" relative to its source instead of applying the invariance postulate. Thus, emitter theory combines electrodynamics and mechanics with a simple Newtonian theory. Although there are still proponents of this theory outside the scientific mainstream, this theory is considered to be conclusively discredited by most scientists.
This residual curvature implies a positive cosmological constant to be determined by observation. Due to the small magnitude of the constant, special relativity with its Poincaré group is indistinguishable from de Sitter space for most practical purposes. Modern proponents of this idea, such as S. Cacciatori, V. Gorini and A. Kamenshchik, have reinterpreted this theory as physics, not just mathematics. They postulate that the acceleration of the expansion of the universe is not entirely due to vacuum energy, but at least partly due to the kinematics of the de Sitter group, which would replace the Poincaré group.
In this way, a Christian teacher could use the text to discuss Virgil without compromising their religious and moral integrity. Clark and Hatch, on the other hand, postulate that Jesus's Virgilian nature in the cento may have been Proba's attempt to rebut the unflattering, demonizing descriptions of Jesus in Julian's Caesares and Contra Galilaeos. They conclude that the hypothesis is intriguing but unverifiable due to the lack of information about Proba, the date of the cento's creation, and her intentions. Finally, the classicist Aurelio Amatucci suggests that Proba composed the cento to teach her children stories from the Bible,Cullhed (2015), pp. 5253.
The council convened April 11–14, 1974, in a Spring "Witchmeet" in Minneapolis, Minnesota to postulate a summary set of principlesTo Ride a Silver Broomstick: New Generation Witchcraft By Silver RavenWolf. which would clarify the actuality of Neopagan religions in North America, unify and define the many differing beliefs across the many paths and traditions prevalent in Neopaganism at that time, and to counteract misinformation, cultural stigma, stereotypes, and lack of governmental recognition. The council was assembled by Carl Llewellyn Weschcke, president of Llewellyn Worldwide Ltd., one of the largest publishers of occult, Neopagan, and New Age books in the world.
Within his or her area of responsibility, the minister is the supreme executive organ. He or she is vested with management authority (), meaning the minister is in charge of setting policy, of most personnel decisions, and of the internal governance and discipline of their respective departments. He or she also has injunction authority (), the power to issue orders () to the civil servants in their respective departments that require or prohibit specific substantive acts and decisions. Both powers follow from the postulate that supreme executive organs hold ultimate responsibility; an organ cannot be considered responsible for what it cannot effectively control.
Natural selection is observed in contemporary human populations, with recent findings demonstrating that the population at risk of the severe debilitating disease kuru has significant over-representation of an immune variant of the prion protein gene G127V versus non-immune alleles. Scientists postulate one of the reasons for the rapid selection of this genetic variant is the lethality of the disease in non-immune persons. Other reported evolutionary trends in other populations include a lengthening of the reproductive period, reduction in cholesterol levels, blood glucose and blood pressure. A well known example of selection occurring in human populations is lactose tolerance.
Generally speaking, the cost of excavation, increased need for damp-proofing and the requirement for the structure to withstand greater weight relative to above grade houses means that earth sheltering remains relatively rare. In this respect, the Passive House (PassivHaus) energy performance standard applied to above grade airtight, superinsulated low carbon or zero carbon buildings has had much wider uptake in modern times. Over 20,000 buildings certified to PassivHaus standards have been constructed across Northern Europe. Some postulate that over time the reducing availability of building space, and the increasing need and interest for environmentally friendly housing will make earth shelters more common.
The principle of equity is related to the constitutional mandate that “health is the right of all”, provided for in the aforementioned article 196 of the Constitution. The aim here is to preserve the postulate of isonomy , since the Constitution itself, in Individual and Collective Rights and Duties , article 5 , establishes that “all are equal before the law, without distinction of any kind”. Therefore, all citizens, equally, must have their health rights guaranteed by the State. However, regional and social inequalities can lead to the innocence of this isonomy, after all, a more needy area may demand more spending compared to others.
The axioms of associativity and unique solutions in the definition of an n-ary group are stronger than they need to be. Under the assumption of n-ary associativity it suffices to postulate the existence of the solution of equations with the unknown at the start or end of the string, or at one place other than the ends; e.g., in the 6-ary case, xabcde=f and abcdex=f, or an expression like abxcde=f. Then it can be proved that the equation has a unique solution for x in any place in the string.
Truth value in this case meaning the > coherence between all of the interacting actors. He added: > It is essential to postulate vectorial times (where components of the > vectors are incommensurate) and furthermore times which interact with each > other in the manner of Louis Kaufmann's knots and tangles. In experimental Epistemology Pask, the "philosopher mechanic", produced a tool kit to analyse the basis for knowledge and criticise the teaching and application of knowledge from all fields: the law, social and system sciences to mathematics, physics and biology. In establishing the vacuity of invariance Pask was challenged with the invariance of atomic number.
Various medical scientists have studied possible trial effect (clinical trial effect) in clinical trials. Some postulate that, beyond just attention and observation, there may be other factors involved, such as slightly better care; slightly better compliance/adherence; and selection bias. The latter may have several mechanisms: (1) Physicians may tend to recruit patients who seem to have better adherence potential and lesser likelihood of future loss to follow-up. (2) The inclusion/exclusion criteria of trials often exclude at least some comorbidities; although this is often necessary to prevent confounding, it also means that trials may tend to work with healthier patient subpopulations.
Early studies, investigating the shape of the stellar halo of the Milky Way, found some evidence that it may vary with increasing distance from the galaxy. These studies found halos with spherically shaped outer regions and flatter inner regions. Large surveys in the 21st century such as the Sloan Digital Sky Survey have allowed the shape and distribution of the stellar halo to be investigated in much more detail; this data has been used to postulate a triaxial or oblate halo. More recent studies have found the halo to be flattened with a broken power law radius dependence; evidence for triaxiality is unclear.
The Stagnum, along with the Euripus were very likely added into the landscape as features to complement the pleasure gardens which Agrippa placed around his baths. The lake is most often placed to the west of the bath structure and, as previously mentioned above, there are, in fact, no references to anyone swimming in the Stagnum, using it in lieu of the lacking swimming pool in the bath structure. Some theories postulate the lake was lined with quays, suggesting that boating on the lake may have been popular. The Stagnum may have been fed by runoff waters from the baths.
Some philosophers, for example R. M. Hare (1919–2002), argue that moral propositions remain subject to human logical rules, notwithstanding the absence of any factual content, including those subject to cultural or religious standards or norms. Thus, for example, they contend that one cannot hold contradictory ethical judgments. This allows for moral discourse with shared standards, notwithstanding the descriptive properties or truth conditions of moral terms. They do not affirm or deny that moral facts exist, only that human logic applies to our moral assertions; consequently, they postulate an objective and preferred standard of moral justification, albeit in a very limited sense.
These models postulate that study items listed last are retrieved from a highly accessible short-term buffer, i.e. the short-term store (STS) in human memory. This allows items that are recently studied to have an advantage over those that were studied earlier, as earlier study items have to be retrieved with greater effort from one’s long-term memory store (LTS). An important prediction of such models is that the presentation of a distraction, for example solving arithmetic problems for 10–30 seconds, during the retention period (the time between list presentation and test) attenuates the recency effect.
7 The Spaniards who explored the region that later became Jerez wrote that they were groups of Guachichiles in the region that had pushed out the Zacatecas that had previously resided there.Gerhard, Peter, The north frontier of New Spain, Princeton, New Jersey, 1982, p. 98 Through this historical evidence one can postulate that the Wixárika arrived in the Bolaños Canyon region around the same time as the Spaniards. The arrival of the Spaniards in territories of the Guachichiles in Zacatecas and San Luis Potosí had certainly brought epidemics to the indigenous communities whose members had no resistance to the diseases of Europe.
The postulates of special relativity can be expressed very succinctly using the mathematical language of pseudo- Riemannian manifolds. The second postulate is then an assertion that the four- dimensional spacetime M is a pseudo-Riemannian manifold equipped with a metric g of signature (1,3), which is given by the Minkowski metric when measured in each inertial reference frame. This metric is viewed as one of the physical quantities of the theory; thus it transforms in a certain manner when the frame of reference is changed, and it can be legitimately used in describing the laws of physics.
Instead the sejm had become preoccupied with the dissident postulate of prosecuting instigators of religious disturbances directed against non-Catholics; advised by Skarga, the King refused his assent to the proposed statute. The nobility opposition, suspecting an attempt against their liberties, called for a rokosz, or an armed confederation. Tens of thousands of disaffected szlachta, led by the ultra-Catholic Mikołaj Zebrzydowski and Calvinist Janusz Radziwiłł, congregated in August near Sandomierz, giving rise to the so-called Zebrzydowski Rebellion. Hetman Stanisław Koniecpolski The Sandomierz articles produced by the rebels were concerned mostly with placing further limitations on the monarch's power.
Equivalent to the original ? No. Test theories of special relativity are flat space-time theories which differ from special relativity by having a different postulate about light concerning one-way speed of light vs two-way speed of light. Different postulates on light result in different notions of time simultaneity. There is Robertson's test theory (1949) which predicts different experimental results from Einstein's special relativity, and then there is Edward's theory (1963) which cannot be called a test theory because it is physically equivalent to special relativity, and then there is the Mansouri-Sexl theory (1977) which is equivalent to Robertson's theory.
A drawing from William Blandowski's 1850s scientific expedition shows Aboriginal people engaged in domestic and recreational activities, including a kicking game with a ball made from Typha roots. Some historians, including Martin Flanagan,Martin Flanagan, The Call. St. Leonards, Allen & Unwin, 1998, p. 8 Martin Flanagan, 'Sport and Culture' Jim Poulter and Col Hutchinson postulate that Tom Wills, who was the son of a politician and a squatter and was educated at Rugby School in England in the 1850s could have been inspired by indigenous Australian pastimes involving possum skin "ball" games (sometimes collectively labeled "Marn Grook").
The paper attributed confusion over pathogenicity to the existence of asymptomatic carriers, a phenomenon the study noted is common to all gastrointestinal protozoa. However, Blastocystis has never fulfilled Koch's postulate that infection of a healthy individual with Blastocystis leads to disease. The fact that Blastocystis' infection route is oral-anal indicates that carriers have been in contact with faecal contaminated matter which might have included other intestinal pathogens that explain the observed symptoms. A more likely explanation is the presence of virulent and non-virulent strains since there exists an enormous genetic variation between different strains (or genotypes).
Shen Kuo referred to the ancient Daoist I Ching in explaining the spiritual processes and attainment of foreknowledge that cannot be attained through "crude traces", which he likens to mathematical astronomy. Nathan Sivin proposes that Shen was the first in history to "make a clear distinction between our unconnected experiences and the unitary causal world we postulate to explain them," which Biderman and Scharfstein state is arguably inherent in the works of Heraclitus, Plato, and Democritus as well.Biderman & Scharfstein (1989), xvii. Shen was a firm believer in destiny and prognostication, and made rational explanations for the relations between them.Sivin (1995), III, 34–35.
The word axiom comes from the Greek word (axíōma), a verbal noun from the verb (axioein), meaning "to deem worthy", but also "to require", which in turn comes from (áxios), meaning "being in balance", and hence "having (the same) value (as)", "worthy", "proper". Among the ancient Greek philosophers an axiom was a claim which could be seen to be self-evidently true without any need for proof. The root meaning of the word postulate is to "demand"; for instance, Euclid demands that one agree that some things can be done (e.g., any two points can be joined by a straight line).
All other assertions (theorems, in the case of mathematics) must be proven with the aid of these basic assumptions. However, the interpretation of mathematical knowledge has changed from ancient times to the modern, and consequently the terms axiom and postulate hold a slightly different meaning for the present day mathematician, than they did for Aristotle and Euclid. The ancient Greeks considered geometry as just one of several sciences, and held the theorems of geometry on par with scientific facts. As such, they developed and used the logico-deductive method as a means of avoiding error, and for structuring and communicating knowledge.
Many growers abandoned their groves entirely, but Mead recognized that below ground artesian water at a constant 70 degrees might provide relief from frost and allow citrus trees to survive freezing temperatures. His engineering background led him to postulate that overhead water irrigation of the trees hanging with fruit could keep the fruit protected from damage at 32° within an ice cocoon regardless of how low the mercury fell. He successfully covered an acre of oranges, installed a pump and irrigation system, and proved the concept, the first known description of a technique still used today.
A contemporary of Hobbes, James Harrington, reacted to the same tumult in a different way: he considered property natural but not inevitable. The author of Oceana, he may have been the first political theorist to postulate that political power is a consequence, not the cause, of the distribution of property. He said that the worst possible situation is one in which the commoners have half a nation's property, with crown and nobility holding the other half—a circumstance fraught with instability and violence. A much better situation (a stable republic) will exist once the commoners own most property, he suggested.
His complete work contained five smaller sets of forms, a 108-move Long Fist routine, and a Cannon Fist routine. Chen is also credited with the invention of the first push hands exercises. Chen also practiced a few Shaolin forms, and some historians postulate that Shaolin arts also had a significant influence on his t'ai chi, though none of the Taoist influences on Chen family t'ai chi exist in the Shaolin tradition. Chen Wangting's next well-known successor was the 14th generation Chen Changxing (1771–1853), who was the direct teacher of the founder of Yang-style tai chi chuan: Yang Luchan.

George Hepburn (died 9 September 1513) was the son of Adam Hepburn and brother to Patrick Hepburn, the first Earl of Bothwell. He was a churchman, and served firstly as postulate Abbot of Arbroath, before becoming Lord High Treasurer of Scotland for a brief spell in 1509. Serving in that role only for a short time, he was consecrated as Bishop of the Isles in 1510 and was also Commendator of the Abbeys of Arbroath and Icolmkill. He was killed at the Battle of Flodden in 1513, as was his brother Adam and his nephew, also Adam, the second Earl of Bothwell.
Usually, the fair sampling assumption (alternatively, the "no-enhancement assumption") is used in regard to this loophole. It states that the sample of detected pairs is representative of the pairs emitted, in which case the right-hand side in the equation above is reduced to 2, irrespective of the efficiency. This comprises a third postulate necessary for violation in low-efficiency experiments, in addition to the (two) postulates of local realism. There is no way to test experimentally whether a given experiment does fair sampling, as the correlations of emitted but undetected pairs is by definition unknown.
Because spherical elliptic geometry can be modeled as, for example, a spherical subspace of a Euclidean space, it follows that if Euclidean geometry is self-consistent, so is spherical elliptic geometry. Therefore it is not possible to prove the parallel postulate based on the other four postulates of Euclidean geometry. Tarski proved that elementary Euclidean geometry is complete: there is an algorithm which, for every proposition, can show it to be either true or false.Tarski (1951) (This does not violate Gödel's theorem, because Euclidean geometry cannot describe a sufficient amount of arithmetic for the theorem to apply.
Since language and communication were very limited in his time, Anaximenes's analogies were key in explaining the uncertain through the certain. For example, he knew for certain that blowing air on his hand with his mouth wide open produced hot air, while blowing on his hand with half-closed lips produced cold air. These observations were key in his postulate that the hot air was due to rarefaction and expansion, whereas the cold air was due to condensation and compression. Although in modern times it is known that this is actually the opposite, Anaximenes was key in arriving at this conclusion.
Preclinical studies of this drug have shown great promise in the treatment of bone resorptive diseases. The high degree of similarity between Hereditary Vitamin D–Resistant Rickets (HVDRR) disease symptoms and observed phenotypes in TRPV6 KO mice has led some experts to postulate pathological connections between the disease and TRPV6 dysfunction. TRPV6 plays an important chondroprotective role by regulating multiple aspects of chondrocyte function, such as extracellular matrix secretion, the release of matrix-degrading enzymes, cell proliferation, and apoptosis. Furthermore, TRPV6 knockout mice display multiple osteoarthritis (OA) phenotypes such as cartilage fibrillation, eburnation, and loss of proteoglycans.
Eric P. Hamp (1976, 91) supports the Graeco-Armenian thesis, anticipating even a time "when we should speak of Helleno-Armenian" (meaning the postulate of a Graeco-Armenian proto-language). Armenian shares the augment, and a negator derived from the set phrase Proto- Indo-European language ("never anything" or "always nothing"), and the representation of word-initial laryngeals by prothetic vowels, and other phonological and morphological peculiarities with Greek. Nevertheless, as Fortson (2004) comments, "by the time we reach our earliest Armenian records in the 5th century AD, the evidence of any such early kinship has been reduced to a few tantalizing pieces".
But according to P. Appell and E. Delassus (1911–1913) the study of nonlinear differential constraints proved these principles to be incompatible. The solution of this problem was completed by N.G. Chetaev (1932–1933), who proposed that the possible displacements of nonlinear constraints be defined by conditions of the special type. Thus, it has been generalized by three physicists, namely E. Mach (1883) who began to solve the problem with postulating one inequality out of two necessary, E. A. Bolotov (1916) who proved this postulate and N. G. Chetaev (1932–1933) who completed the work extended over 50 years.
There were some attempts to derive the Lorentz transformation without the postulate of the constancy of the speed of light. Vladimir Ignatowski (1910) for example used for this purpose (a) the principle of relativity, (b) homogeneity and isotropy of space, and (c) the requirement of reciprocity. Philipp Frank and Hermann Rothe (1911) argued that this derivation is incomplete and needs additional assumptions. Their own calculation was based on the assumptions that: (a) the Lorentz transformation forms a homogeneous linear group, (b) when changing frames, only the sign of the relative speed changes, (c) length contraction solely depends on the relative speed.
This rule has been claimed by some homeopaths as supporting their hypotheses. However, this rule does not apply to the extremely high dilutions typically used by homeopaths, which have a high probability of containing no molecules of the diluted substance. To explain the purported therapeutic powers of homeopathic remedies (only for ultra high dilutes) Jacques Benveniste created the postulate of "water memory". The water memory hypothesis defies conventional scientific understanding of physicochemical knowledge through which the perceived effect of a chemical compound after its removal from a solution is not expectable due to the assumption no molecules, no effect.
2820 foll. 33ra–171vb in the Austrian National Library). In the 16th and 17th centuries, the popularity of the chronicle waned rapidly due to its assumed fictional content, and it remained unedited until the early 20th century. Since its edition, it has played a certain role in pseudohistory, in particular in US American Biblical literalism, in publications such as those of Herman L. Hoeh"Compendium of World History" (1963) and Herbert W. Armstrong Here's the Plain Truth About Old Testament Polygamy (1963) of the Worldwide Church of God, who took the chronicle's genealogies at face value to postulate that, e.g.
Four years later, around 1996, with Drumlin seeking to close the SETI program, Arroway discovers a signal repeating a sequence of prime numbers, apparently sent from the star system Vega about 26 light-years away. This announcement causes Drumlin and the National Security Council led by Michael Kitz to attempt to take control of the facility. Arroway's team discovers a video hidden in the signal: Adolf Hitler's opening address at the 1936 Summer Olympics in Berlin, Germany. Arroway and her team postulate that this would have been the first signal strong enough to leave Earth's ionosphere, reach Vega, and be transmitted back.
Bohm's interpretation of QM does not sit well with RQM. One of the explicit hypotheses in the construction of RQM is that quantum mechanics is a complete theory, that is it provides a full account of the world. Moreover, the Bohmian view seems to imply an underlying, "absolute" set of states of all systems, which is also ruled out as a consequence of RQM. We find a similar incompatibility between RQM and suggestions such as that of Penrose, which postulate that some process (in Penrose's case, gravitational effects) violate the linear evolution of the Schrödinger equation for the system.
Both of these paradoxes involve thought experiments which defy traditional common sense assumptions about time and space. In particular, the effects of time dilation and length contraction are used in both of these paradoxes to create situations which seemingly contradict each other. It turns out that the fundamental postulate of special relativity that the speed of light is invariant in all frames of reference requires that concepts such as simultaneity and absolute time are not applicable when comparing radically different frames of reference. Another paradox associated with relativity is Supplee's paradox which seems to describe two reference frames that are irreconcilable.
The pukao was balanced as a separate piece on top of the head of a moai. They are believed to have been raised using ramps, possibly requiring only several people. The ring-like indentations along the bottom and edges of the pukao support this theory, as they postulate a ramp made out of logs being used to roll the pukao to the tops of moai statues. In addition, various physicists have made models indicating that this as a possibility, and, given the oblong shape of pukao, the structures would have been easier to roll up the statue than roll back down.
On one hand, statistical mechanics is far superior to classical thermodynamics, in that thermodynamic behavior, such as glass breaking, can be explained by the fundamental laws of physics paired with a statistical postulate. But statistical mechanics, unlike classical thermodynamics, is time-reversal symmetric. The second law of thermodynamics, as it arises in statistical mechanics, merely states that it is overwhelmingly likely that net entropy will increase, but it is not an absolute law. Current thermodynamic solutions to the problem of the direction of time aim to find some further fact, or feature of the laws of nature to account for this discrepancy.
Ivan Emanuel Wallin (22 January 1883 – 6 March 1969) was an American biologist who made the first experimental works on endosymbiotic theory. Nicknamed the "Mitochondria Man", he claimed that mitochondria, which are cell organelles, were once independent bacteria, as supported by his comparative studies and culture of isolated mitochondria. From 1922, he published a series of papers titled "On the nature of mitochondria" in the American Journal of Anatomy which became the experimental foundations of his claims. He was the first person to specifically postulate that eukaryotic organelles originated from bacteria, and that symbiosis is a major force in creation of new species.
Hume noted the formal illogicality of enumerative induction—unrestricted generalization from particular instances to all instances, and stating a universal law—since humans observe sequences of sensory events, not cause and effect. Perceiving neither logical nor natural necessity or impossibility among events, humans tacitly postulate uniformity of nature, unproved. Later philosophers would select, highlight, and nickname Humean principles—Hume's fork, the problem of induction, and Hume's law—although Hume respected and accepted the empirical sciences as inevitably inductive, after all. Immanuel Kant, in Germany, alarmed by Hume's seemingly radical empiricism, identified its apparent opposite, rationalism, in Descartes, and sought a middleground.
Ramos decided to postulate his name for Governor of the Department of Antioquia in the regional elections of 2007 representing the Alas Equipo Colombia political party. Ramos was elected Governor of the Department of Antioquia on October 28, 2007 obtaining of 99.04% of the voting sites scrutinized 836,526 votes equivalent to 51.73% of the total votes (1,617,065 total votes). Ramos defeated candidate Eugenio Prieto Soto of the del Movimiento Una Antioquia Nueva, who obtained 579,020 votes. Ramos will be inaugurated as governor on January 1, 2008 for a period of 3 years until December 31, 2011.
At the end of chapter 4 ("Why there almost certainly is no God"), Dawkins sums up his argument and states, "The temptation [to attribute the appearance of design to actual design itself] is a false one, because the designer hypothesis immediately raises the larger problem of who designed the designer. The whole problem we started out with was the problem of explaining statistical improbability. It is obviously no solution to postulate something even more improbable".The God Delusion, page 158 In addition, chapter 4 asserts that the alternative to the designer hypothesis is not chance, but natural selection.
Maurrassisme had as its ambition to be a counter- revolutionary doctrine, affirming the cohesion of France and its greatness. It began from a slogan "Politics first", from a postulate, patriotism, which the French Revolution had erased in preference to nationalism, and a state: for Maurras, the French society of the late 19th century was undermined by decadence and corruption. According to him, these ills arose from the Revolution and caused their paroxysm in the Dreyfus affair. Maurras' philosophical influences ranged from Plato and Aristotle to Joseph de Maistre, passing through Dante, Thomas Aquinas and Auguste Comte.
In short, the postulate states that "energy efficiency improvements that, on the broadest considerations, are economically justified at the microlevel, lead to higher levels of energy consumption at the macrolevel." This idea is a more modern analysis of a phenomenon known as the Jevons Paradox. In 1865, William Stanley Jevons observed that England's consumption of coal increased considerably after James Watt introduced his improvements to the steam engine. Jevons argued that increased efficiency in the use of coal would tend to increase the demand for coal, and would not reduce the rate at which England's deposits of coal were running out.
The revised draft also created a scandal as it was claimed to contain racist, xenophobic and nationalist passages. Critics accused the authors to argue just as völkisch-ly and to adopt the neo-rightist concept of ethnopluralism despite their limiting remarks and their distancing from racism and right-wing extremism. Ethnopluralism claims to postulate no intrinsic hierarchy between peoples but regards them as worthy of preservation and threatened by 'amalgamation'. During the course of the extensive media coverage, both of the Manifesto's versions were printed verbatim by various newspapers in 1982, as a document of their time.
Since Euclid, geometry had meant the geometry of Euclidean space of two dimensions (plane geometry) or of three dimensions (solid geometry). In the first half of the nineteenth century there had been several developments complicating the picture. Mathematical applications required geometry of four or more dimensions; the close scrutiny of the foundations of the traditional Euclidean geometry had revealed the independence of the parallel postulate from the others, and non-Euclidean geometry had been born. Klein proposed an idea that all these new geometries are just special cases of the projective geometry, as already developed by Poncelet, Möbius, Cayley and others.
The concept of two distinct symmetric states is the central postulate of the MWC model. The main idea of the model is that regulated proteins, such as many enzymes and receptors, exist in different interconvertible states in the absence of any regulator. The ratio of the different conformational states is determined by thermal equilibrium. This model, alternatively termed the MWC model, is defined by the following rules: # An allosteric protein is an oligomer of protomers that are symmetrically related (for hemoglobin, we shall assume, for the sake of algebraic simplicity, that all four subunits are functionally identical).
Gabrielle Émilie Le Tonnelier de Breteuil, Marquise du Châtelet (; 17 December 1706 – 10 September 1749) was a French natural philosopher and mathematician during the early 1730s until her untimely death due to childbirth complications in 1749. Her most recognized achievement is her translation of and commentary on Isaac Newton's 1687 book Principia containing basic laws of physics. The translation, published posthumously in 1756, is still considered the standard French translation today. Her commentary includes a profound contribution to Newtonian mechanics—the postulate of an additional conservation law for total energy, of which kinetic energy of motion is one element.
He also gave the first satisfactory proofs of the fundamental theorem of algebra and of the quadratic reciprocity law. Behavior of lines with a common perpendicular in each of the three types of geometry This century saw the development of the two forms of non-Euclidean geometry, where the parallel postulate of Euclidean geometry no longer holds. The Russian mathematician Nikolai Ivanovich Lobachevsky and his rival, the Hungarian mathematician János Bolyai, independently defined and studied hyperbolic geometry, where uniqueness of parallels no longer holds. In this geometry the sum of angles in a triangle add up to less than 180°.
Noam Chomsky is usually associated with the term universal grammar in the 20th and 21st centuries Universal grammar (UG), in modern linguistics, is the theory of the genetic component of the language faculty, usually credited to Noam Chomsky. The basic postulate of UG is that a certain set of structural rules are innate to humans, independent of sensory experience. With more linguistic stimuli received in the course of psychological development, children then adopt specific syntactic rules that conform to UG. It is sometimes known as "mental grammar", and stands contrasted with other "grammars", e.g. prescriptive, descriptive and pedagogical.
According to Hoyland, taxation-related grievances of non-Arab Muslims contributed to the opposition movements which resulted in the Abbasid revolution. In contrast, Dennett states that it is incorrect to postulate an economic interpretation of the Abbasid revolution. The notion of an Iranian population staggering under a burden of taxation and ready to revolt at the first opportunity, as imagined by Gerlof van Vloten, "will not bear the light of careful investigation", he continues. Under the new system that was eventually established, kharaj came to be regarded as a tax levied on the land, regardless of the taxpayer's religion.
In addition to the independence of the parallel postulate, established by Nikolai Lobachevsky in 1826 (Lobachevsky 1840), mathematicians discovered that certain theorems taken for granted by Euclid were not in fact provable from his axioms. Among these is the theorem that a line contains at least two points, or that circles of the same radius whose centers are separated by that radius must intersect. Hilbert (1899) developed a complete set of axioms for geometry, building on previous work by Pasch (1882). The success in axiomatizing geometry motivated Hilbert to seek complete axiomatizations of other areas of mathematics, such as the natural numbers and the real line.
Chichen Itza One of the most controversial topics involving the Toltecs is what their relationship with Chichén Itzá was. The similarities between the two cities has raised several hypotheses about the nature of the links between the two, although none of them have the full support of the specialists in the field. In the 19th century, French archaeologist Désiré Charnay was the first person who pointed out that the main plazas of Tula and Chichen Itza were similar, a fact that led him to postulate that the city could have been conquered by Toltecs led by Topiltzin Quetzalcoatl, who Charnay referred as Kukulkan.Charnay, D. (1885) La Civilisation Tolteque.
According to more current literature, gill-like structures and the paranotal lobe still appear to be among the most important ancestral structures to insect wing origins. Today, there are three main theories on the origins of insect flight. These theories are referred to as the paranotal lobe theory, the gill theory and the dual theory of insect wing evolution. These theories postulate that wings either developed from paranotal lobes, extensions of the thoracic terga; that they are modifications of movable abdominal gills as found on aquatic naiads of mayflies; or that insect wings arose from the fusion of pre-existing endite and exite structures each with pre-existing articulation and tracheation.
On 3 March 2011, Pope Benedict XVI was presented with a statue of the apparition by Bishop Guillermo Afable during the Catholic Bishops' Conference of the Philippines Ad Limina visit. On 9 March 2011, a life-sized statue brought by Filipino bishops was publicly displayed in the general Wednesday papal audience at Pope Paul VI Audience Hall. On 12 September 2015, Archbishop Argüelles formally released the canonical results of the investigation launched by the archdiocese, declaring the Marian apparitions to be "supernatural in character and worthy of pious belief". At present, a postulate for Canonical Coronation is pending submission to Pope Francis for pontifical approbation.
Soon afterward, in 1817, Francis I of Austria called for a new sejm, now named the Estates of Galicia (), which met again in Lviv. Most scholars, like Jacek Jędruch, see this body as a continuation of the Postulate Sejm, and discuss both of them together. The Austrian Emperor decreed that the members have to wear a special uniform; this made it the only Polish parliament-like body in the history of Polish politics with a dress code requirement. Excepting the establishment of the Ossolineum as a center for Polish cultural study, the Sejm reflected the conservative attitudes of the body's unelected members from the nobility and the landed gentry.
For example, they may postulate the existence of basic entities such as value, beauty, and God. Then they use these postulates to make their own arguments about consequences resulting from them. When philosophers in these subjects make their foundations they are doing applied metaphysics, and may draw upon its core topics and methods to guide them, including ontology and other core and peripheral topics. As in science, the foundations chosen will in turn depend on the underlying ontology used, so philosophers in these subjects may have to dig right down to the ontological layer of metaphysics to find what is possible for their theories.
The early to mid twentieth century philosophy saw a trend to reject metaphysical questions as meaningless. The driving force behind this tendency was the philosophy of logical positivism as espoused by the Vienna Circle, which argued that the meaning of a statement was its prediction of observable results of an experiment, and thus that there is no need to postulate the existence of any objects other than these perceptual observations. At around the same time, the American pragmatists were steering a middle course between materialism and idealism. System-building metaphysics, with a fresh inspiration from science, was revived by A.N. Whitehead and Charles Hartshorne.
Therefore, Lorentz's theorem is seen by modern authors as being a mathematical transformation from a "real" system resting in the aether into a "fictitious" system in motion. The work of Lorentz was mathematically perfected by Henri Poincaré, who formulated on many occasions the Principle of Relativity and tried to harmonize it with electrodynamics. He declared simultaneity only a convenient convention which depends on the speed of light, whereby the constancy of the speed of light would be a useful postulate for making the laws of nature as simple as possible. In 1900 and 1904 he physically interpreted Lorentz's local time as the result of clock synchronization by light signals.
The central idea of these theories is that language development occurs through the incremental acquisition of meaningful chunks of elementary constituents, which can be words, phonemes, or syllables. Recently, this approach has been highly successful in simulating several phenomena in the acquisition of syntactic categories and the acquisition of phonological knowledge. Chunking theories of language acquisition constitute a group of theories related to statistical learning theories, in that they assume that the input from the environment plays an essential role; however, they postulate different learning mechanisms. Researchers at the Max Planck Institute for Evolutionary Anthropology have developed a computer model analyzing early toddler conversations to predict the structure of later conversations.
In general, memory span for verbal contents (digits, letters, words, etc.) strongly depends on the time it takes to speak the contents aloud. Some researchers have therefore proposed that the limited capacity of short-term memory for verbal material is not a "magic number" but rather a "magic spell". Baddeley used this finding to postulate that one component of his model of working memory, the phonological loop, is capable of holding around 2 seconds of sound. However, the limit of short-term memory cannot easily be characterized as a constant "magic spell" either, because memory span also depends on other factors besides speaking duration.
Unlike most western scholars who preceded them, including classical liberals, classical Marxists, empiricists, dialectical thinkers and positivists, historical institutionalists do not accept that history necessarily develops in a straightforward, linear fashion. Instead, they examine the conditions under which a particular trajectory was followed and not others, a phenomenon that Gabriel Almond refers to as the "historical cure".. As a consequence, specifying why particular paths were not taken is as important as specifying the actual trajectory of history. As opposed to the old institutionalists, they postulate that history will not necessarily lead to a "happy" outcome (i.e. "fascism or democracy as the end of history").
In the case of Vernaccia di Oristano, ampelographers believe that the grape may be native to the Tirso river valley that crosses the island of Sardinia before emptying into the Gulf of Oristano. The province of Oristano where Vernaccia di Oristano may have originated. Also shown on the map is the location of the ruins of the Phoenician settlement of Tharros on the coast of the Gulf of Oristano. Other theories postulate that the name could be derived from other Latin words such as verrum, meaning boar, based on the beasts that are common in central Italy and known to trespass into vineyard and eat the grapes on the vine.
Gauss also claimed to have discovered the possibility of non-Euclidean geometries but never published it. This discovery was a major paradigm shift in mathematics, as it freed mathematicians from the mistaken belief that Euclid's axioms were the only way to make geometry consistent and non- contradictory. Research on these geometries led to, among other things, Einstein's theory of general relativity, which describes the universe as non- Euclidean. His friend Farkas Wolfgang Bolyai with whom Gauss had sworn "brotherhood and the banner of truth" as a student, had tried in vain for many years to prove the parallel postulate from Euclid's other axioms of geometry.
The collection is made up of a large number of mammal fossils belonging to the South American Quaternary, including a human skeleton called Samborombón considered to be the star of the collection. It was the focus of a great amount of scientific discussions in the early 20th century due to the postulate of the tertiary antiquity of the origin of mankind. He was accompanied by Enrique De Carles, the main fossil collector and naturalist technician of the Museum of Buenos Aires. He was the main person in charge of the mounting of the skeletons until his early leaving in June 1890, when the city of Valencia suffered the last cholera outbreak.
In Blood Music, reality becomes unstable as the number of observers (trillions of intelligent single-cell organisms) spirals higher and higher. Anvil of Stars (sequel to The Forge of God) and Moving Mars postulate a physics based on information exchange between particles, capable of being altered at the "bit level." (Bear has credited the inspiration for the idea to Frederick Kantor's 1967 treatise "Information Mechanics" (see Digital physics)) In Moving Mars, that knowledge is used to remove Mars from the solar system and transfer it to an orbit around a distant star. Blood Music was first published as a short story (1983) and then expanded to a novel (1985).
In speculative fiction, the line between dreams and reality may be blurred even more in the service of the story. Dreams may be psychically invaded or manipulated (Dreamscape, 1984; the Nightmare on Elm Street films, 1984–2010; Inception, 2010) or even come literally true (as in The Lathe of Heaven, 1971). In Ursula K. Le Guin's book, The Lathe of Heaven (1971), the protagonist finds that his "effective" dreams can retroactively change reality. Peter Weir's 1977 Australian film The Last Wave makes a simple and straightforward postulate about the premonitory nature of dreams (from one of his Aboriginal characters) that "... dreams are the shadow of something real".
Initially, de Broglie proposed a double solution approach, in which the quantum object consists of a physical wave (u-wave) in real space which has a spherical singular region that gives rise to particle-like behaviour; in this initial form of his theory he did not have to postulate the existence of a quantum particle. He later formulated it as a theory in which a particle is accompanied by a pilot wave. De Broglie presented the pilot wave theory at the 1927 Solvay Conference. However, Wolfgang Pauli raised an objection to it at the conference, saying that it did not deal properly with the case of inelastic scattering.
Corbu, followed by Baigent, Leigh, and Lincoln, asserts that Rennes-le-Château had been the capital of the Visigothic Kingdom Rhedae, while other sources postulate Rhedae's hub as Narbonne. Corbu's claim can be traced back to a book by Louis Fédié entitled Le comté de Razès et le diocèse d'Alet (1880), that contained a chapter on the history of Rennes-le- Château; published as a booklet in 1994.Louis Fédié, Rhedae, la Cité des Chariots (Rennes-le-Château: Terre de Rhedae, 1994). Noël Corbu incorporated this story into his essay L'histoire de Rennes-le-Château, deposited at the Departmental Archives at Carcassonne on 14 June 1962.
Hinduism does not have a "unified system of belief encoded in a declaration of faith or a creed", but is rather an umbrella term comprising the plurality of religious phenomena of India. According to the Supreme Court of India, Part of the problem with a single definition of the term Hinduism is the fact that Hinduism does not have a founder. It is a synthesis of various traditions,; the "Brahmanical orthopraxy, the renouncer traditions and popular or local traditions". Theism is also difficult to use as a unifying doctrine for Hinduism, because while some Hindu philosophies postulate a theistic ontology of creation, other Hindus are or have been atheists.
Some historians postulate that Jinnah always remained hopeful for an agreement with the Congress and never fully desired the partition of India.Ayesha Jalal, The Sole Spokesman, pp. 14 Iqbal's close correspondence with Jinnah is speculated by some historians as having been responsible for Jinnah's embrace of the idea of Pakistan. Iqbal elucidated to Jinnah his vision of a separate Muslim state in a letter sent on 21 June 1937: Iqbal, serving as president of the Punjab Muslim League, criticised Jinnah's political actions, including a political agreement with Punjabi leader Sikandar Hyat Khan, whom Iqbal saw as a representative of feudal classes and not committed to Islam as the core political philosophy.
Banks even went so far as to postulate that if the Alden and Mullins families both originated from Southampton, then perhaps the courtship between John Alden and Priscilla Mullins began in Southampton. Alicia Crane Williams analyzed these and several other theories in The Mayflower Descendant, a scholarly journal of Pilgrim history and genealogy. She pointed out that some genealogists have connected John Alden of the Mayflower with John Alden, a gentleman, "son and heir of John Alden of Swanscomb, Kent", who obtained a Patent of Arms in 1607. There is no evidence that John Alden of the Mayflower was connected to this family or inherited this coat of arms.
Although phrenology extended into Latter Day Saint life as a cultural phenomenon, the LDS Church never threw its full support behind phrenology. Historians Davis Bitton and Gary Bunker postulate that this might be due to the appeal of a phrenological reading already being filled by a patriarchal blessing. LDS Church president Ezra Taft Benson described a patriarchal blessing as "personal scripture ... the inspired and prophetic statement of your life’s mission together with blessings, cautions, and admonitions as the patriarch may be prompted to give" that should be used as a guide in ones life.Ezra Taft Benson, "To the 'Youth of the Noble Birthright'", Ensign, May 1986, pp.
One of the earliest thinkers of the modern age to postulate the potentials of artificial life, separate from artificial intelligence, was math and computer prodigy John von Neumann. At the Hixon Symposium, hosted by Linus Pauling in Pasadena, California in the late 1940s, von Neumann delivered a lecture titled "The General and Logical Theory of Automata." He defined an "automaton" as any machine whose behavior proceeded logically from step to step by combining information from the environment and its own programming, and said that natural organisms would in the end be found to follow similar simple rules. He also spoke about the idea of self-replicating machines.
Furthermore, Von Morlot (1847 A) expressed his astonishment over the fact, that Arduino had ventured to postulate this far-reaching chemical process for the formation of dolomite merely on the basis of field observations only. At the same time Von Morlot mentioned the (field) observations made by Leopold von Buch (1824),Buch, L. von (1824): Ueber die Lagerungs-Verhältnisse der Kalkschichten mit Fisch-Abdrücken und über den Dolomit im Frankenlande. Taschenbuch für die gesammte Mineralogie mit Hinsicht auf die neuesten Entdeckungen (Von Leonhard, 1824, pp.239-260. who had found fossils in what once must have been limestone, but that now consisted of dolomite.
The first half of the 14th century saw the scientific work of great thinkers. The logic studies by William of Occam led him to postulate a specific formulation of the principle of parsimony, known today as Occam's razor. This principle is one of the main heuristics used by modern science to select between two or more underdetermined theories, though it is only fair to point out that this principle was employed explicitly by both Aquinas and Aristotle before him. As Western scholars became more aware (and more accepting) of controversial scientific treatises of the Byzantine and Islamic Empires these readings sparked new insights and speculation.
Bertrand's postulate, proven in 1852, states that there is always a prime number between k and 2k, so in particular pn+1 < 2pn, which means gn < pn. The prime number theorem, proven in 1896, says that the average length of the gap between a prime p and the next prime will asymptotically approach ln(p) for sufficiently large primes. The actual length of the gap might be much more or less than this. However, one can deduce from the prime number theorem an upper bound on the length of prime gaps: For every \epsilon > 0, there is a number N such that for all n > N :g_n < p_n\epsilon.
His 1902 axiomatization of the real numbers has been characterized as "one of the first successes of abstract mathematics" and as having "filled the last gap in the foundations of Euclidean geometry". Huntington excelled at proving axioms independent of each other by finding a sequence of models, each one satisfying all but one of the axioms in a given set. His 1917 book The Continuum and Other Types of Serial Order was in its day "...a widely read introduction to Cantorian set theory" (Scanlan 1999). Yet Huntington and the other American postulate theorists played no role in the rise of axiomatic set theory then taking place in continental Europe.
Albert Einstein formulated the theory of special relativity by 1905, deriving the Lorentz transformation and thus length contraction and time dilation from the relativity postulate and the constancy of the speed of light, thus removing the ad hoc character from the contraction hypothesis. Einstein emphasized the kinematic foundation of the theory and the modification of the notion of space and time, with the stationary aether no longer playing any role in his theory. He also pointed out the group character of the transformation. Einstein was motivated by Maxwell's theory of electromagnetism (in the form as it was given by Lorentz in 1895) and the lack of evidence for the luminiferous aether.
From these cases, Freud inferred the existence of motivations beyond the pleasure principle. Freud already felt in 1919 that he could safely postulate "the principle of a repetition compulsion in the unconscious mind, based upon instinctual activity and probably inherent in the very nature of the instincts—a principle powerful enough to overrule the pleasure-principle".Sigmund Freud, "The Uncanny" (1919), in Studies in Parapsychology (Alix Strachey trans.). p. 44. In the first half of Beyond the Pleasure Principle, "a first phase, the most varied manifestations of repetition, considered as their irreducible quality, are attributed to the essence of drives"Jean Laplanche, Life and Death in Psychoanalysis (London 1976). p. 107.
In philosophy, spiritualism is the notion, shared by a wide variety of systems of thought, that there is an immaterial reality that cannot be perceived by the senses.Encyclopædia Britannica, "Spiritualism (in philosophy)", britannica.com This includes philosophies that postulate a personal God, the immortality of the soul, or the immortality of the intellect or will, as well as any systems of thought that assume a universal mind or cosmic forces lying beyond the reach of purely materialistic interpretations. Generally, any philosophical position, be it dualism, monism, atheism, theism, pantheism, idealism or any other, is compatible with spiritualism as long as it allows for a reality beyond matter.
Theories of space that are inspired by the post-colonialism discourse focus on the heterogeneity of spaces. According to Doreen Massey, calling a country in Africa a “developing country” is not appropriate, since this expression implies that spatial difference is temporal difference (Massey 1999b). This logic treats such a country not as different but merely as an early version of countries in the “developed” world, a view she condemns as "Eurocentrism." In this vein, Helmuth Berking criticises theories that postulate the increasing homogenisation of the world through globalisation as “globocentrism.” He confronts this with the distinctiveness and importance of local knowledge resources for the production of (different and specific) places.
After his death in 2006 his widow and daughter learned the truth that Aarons had grown up in a poor immigrant Yiddish-speaking family on the Lower East Side of Manhattan. As a boy his mother was diagnosed with mental health issues and admitted to a psychiatric hospital, which caused him to be passed around among relatives. He resented and had no relationship with his father and had a brother, Harry, who would later commit suicide. Several documentary interviewees postulate that if Aarons’s true origins had been known, his career would have been unlikely to succeed within the restricted world of celebrity and WASP privilege his photography glamorized.
The ethnic identity of the Sotiates is debated. Their lifestyle was very similar to that of the Gauls, which led some scholars to postulate that they were originally a Gallic people that had settled at the frontier of Aquitania. In the mid-first century BCE, led by their chief Adiatuanos, the Sotiates fought alone against the Roman armies of Crassus, whereas other Aquitani tribes had formed a coalition against the foreign invader. Furthermore, the name Adiatuanos is probably related to the Gaulish adiantu- ('eagerness, desire, ambition'; perhaps cognate with the Middle Welsh add-iant 'wish'), and thus may be translated as 'zealously striving (for rulership)'.
The problem with this view is that an object that collides with another would not be able to bounce back, if the only force in play were the conatus. Hence, Leibniz was forced to postulate the existence of an aether that kept objects moving and allowed for elastic collisions. Leibniz' concept of a mind- like memory-less property of conatus, coupled with his rejection of atoms, eventually led to his theory of monads. Leibniz also uses his concept of a conatus in developing the principles of the integral calculus, adapting the meaning of the term, in this case, to signify a mathematical analog of Newton's accelerative "force".
This research does not fulfil the four criteria points known as Koch's postulate to establish a causal relationship between a causative microbe and a disease. Other research with an inoculant derived from birds with ABV-only infections (with no PDD histopathological changes) did not develop any signs of PDD. These birds were carefully monitored over extended periods, well exceeding the documented 90-day inoculation period for PDD, yet failed to show any signs of PDD. However, the differences in responses to the experimental infections may be associated to ABV strain variation in pathogenicity, the chronic nature of the infection and the difficulty in standardizing the experimental hosts.
Roddy Collins, former manager of Bohemians, Shamrock Rovers and Maltese side Floriana, lived in Cabra before being appointed manager of Cork City. The suburb's most infamous former resident was John Toler, 1st Earl of Norbury, otherwise known as the hanging judge, who lived at Cabragh House on the corner of the present day Fassaugh Avenue and Ratoath Road. One of the world's most famous mathematicians, William Rowan Hamilton, who freed algebra from the commutative postulate of multiplication (that the order or sequence of factors does not determine the result) was associated with the area. There is a plaque in his honour at the Broom Bridge.
The Marquis de > Sade: a very short introduction. Oxford: Oxford University Press. pp.37-38. > . However, Steven Barbone, of San Diego State University notes that: > We can postulate one of two things: Sade was entirely pleased with this > manuscript and saw no reason to make any changes to it or Sade completely > gave up on the dialogue and had decided to abandon it. The reason for either > of these hypotheses is that the manuscript itself contains almost no trace > of Sade’s editing. It is up to the reader to divine whether the “Dialogue > between the Priest and a Dying Man” is Sade’s position or not.
Laboratory simulations have led to the suggestion that enough organic material exists on Titan to start a chemical evolution analogous to what is thought to have started life on Earth. The analogy assumes the presence of liquid water for longer periods than is currently observable; several hypotheses postulate that liquid water from an impact could be preserved under a frozen isolation layer. It has also been hypothesized that liquid-ammonia oceans could exist deep below the surface. Another model suggests an ammonia–water solution as much as deep beneath a water-ice crust with conditions that, although extreme by terrestrial standards, are such that life could survive.
Finally, the use of multivariate methods that probe for the latent structure of the data, such as factor analysis and cluster analysis, have proven useful as analytic approaches that go well beyond the bi-variate approaches (cross- tabs) typically employed with smaller data sets. In health and biology, conventional scientific approaches are based on experimentation. For these approaches, the limiting factor is the relevant data that can confirm or refute the initial hypothesis. A new postulate is accepted now in biosciences: the information provided by the data in huge volumes (omics) without prior hypothesis is complementary and sometimes necessary to conventional approaches based on experimentation.
Under his reasoning, he envisioned light as a disturbance caused by rippling in the higher dimension just beyond human perception, similar to how fish in a pond can only see shadows of ripples across the surface of the water caused by raindrops. While not detectable, it would indirectly imply a connection between seemingly unrelated forces. The KaluzaKlein theory experienced a revival in the 1970s due to the emergence of superstring theory and supergravity: the concept that reality is composed of vibrating strands of energy, a postulate only mathematically viable in ten dimensions or more. Superstring theory then evolved into a more generalized approach known as M-theory.
Magnetic field lines can be clearly visualized by sprinkling iron filings over a bar magnet. The modern (post-Einstein) interpretation is that the magnetic field is equivalent to the electric field, but in a different reference frame. Since magnetic fields can be interpreted as electric fields in a different reference frame (and vice versa), special relativity connects the two fields. One postulate of special relativity is length contraction, and because of that, the charge density in the wire increases, so a current-carrying wire viewed in a moving reference frame experiences a length-contracted coulomb force as compared to the wire in a stationary frame.
The author names the disease, lists the known symptoms, gives the treatment and sometime indicates the prognosis. He often cited in reference the names of foreign authors, as if to give importance to his subject, or for intellectual integrity to justify the loans. As al-Razi Muhammad ibn Zakariya al-Razi, preceded him by a few decades and as Ibn Al Jazzar has adopted in the Viaticum the same style as "El Hawi" (The Continent: who voluntarily abstain from carnal pleasures) of al-Razi but more elaborate and more concise. Given this many postulate al-Razi’s works were introduced to him at a very young age.
Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has the value , or about . Above about , particle energies become so large that gravitational forces between them would become as strong as other fundamental forces according to current theories. There is no existing scientific theory for the behavior of matter at these energies; a quantum theory of gravity would be required. The models of the origin of the universe based on the Big Bang theory assume that the universe passed through this temperature about (one Planck time) after the Big Bang as a result of enormous entropy expansion.
Democritus, Greek philosopher of atomistic school. Philosophical attempts to rationalize why different substances have different properties (color, density, smell), exist in different states (gaseous, liquid, and solid), and react in a different manner when exposed to environments, for example to water or fire or temperature changes, led ancient philosophers to postulate the first theories on nature and chemistry. The history of such philosophical theories that relate to chemistry can probably be traced back to every single ancient civilization. The common aspect in all these theories was the attempt to identify a small number of primary classical elements that make up all the various substances in nature.
Initially, the Polish government chose to not delay the presidential election, a decision which caused controversy.In April 2020, in the wake of the COVID-19 pandemic, the Agreement's leadership strongly insisted on implementing an appropriate amendment to the Constitution of the Republic of Poland so that Andrzej Duda's term would be prolonged by two years, with no chance for re-election in return. The Agreement's MPs issued appeals for all the parliamentary parties' approval, invoking the legal requirement of a 2/3 supermajority to enact their postulate. This proposal was supported by the Minister of Health, Łukasz Szumowski, however, this was rejected by the opposition.
According to the characters of the play, Ptydepe was constructed along strictly scientific lines, with none of the messiness and ambiguity of natural languages. In order to be able to express precisely all the subtle and easily misunderstood nuances of natural language, Ptydepe has a large, non-expandable vocabulary. Another problem of natural language that Ptydepe was intended to eliminate is the frequent similarity of unrelated words, or homonyms. To entirely avoid the possibilities for confusion that arise with homonyms and similar unrelated words, Ptydepe was created according to the postulate that all words must be formed from the least probable combinations of letters.
The influence of Hicks's paper on subsequent work was partly through the extension of his model in Franco Modigliani's 'Liquidity preference and the theory of interest and money'.Econometrica, 1944, reprinted in Henry Hazlitt (ed.) 'The critics of Keynesian economics'. Modigliani takes Hicks's equations (including the 'first postulate' which Keynes and Hicks had left to one side), expressing quantities in money terms (and therefore, like Hicks, assuming that the schedule of the marginal efficiency of capital determines the amount of investment in money terms whose return will be greater than r – see wage unit). He concluded that 'except in a limiting case' it was 'rigid wages' which accounted for Keynesian unemployment.
However, most Mayanists do not believe that foreign invasion was the main cause of the Classic Maya collapse; they postulate that no military defeat can explain or be the cause of the protracted and complex Classic collapse process. Teotihuacan influence across the Maya region may have involved some form of military invasion; however, it is generally noted that significant Teotihuacan-Maya interactions date from at least the Early Classic period, well before the episodes of Late Classic collapse.See Braswell(2003) The foreign invasion theory does not answer the question of where the inhabitants went. David Webster believed that the population should have increased because of the lack of elite power.
The Sapir–Whorf hypothesis postulates that a person's language influences their perceptions and cognitive patterns. Stanislav Kozlovsky proposed in the Russian popular-scientific magazine Computerra that a fluent speaker of Ithkuil, accordingly, would think "about five or six times as fast" as a speaker of a typical natural language. The Sapir–Whorf hypothesis would suggest that, Ithkuil being an extremely precise and synthetic language, its speakers would have a more discerning, deeper understanding both of everyday situations and of broader phenomena, and of abstract philosophical categories. However, strong forms of the hypothesis, which postulate that language determines thought and not only influences it, have been disproven within mainstream linguistics.
In 1927, George Paget Thomson discovered the interference effect was produced when a beam of electrons was passed through thin metal foils and by American physicists Clinton Davisson and Lester Germer by the reflection of electrons from a crystal of nickel. orbital, which is a probability distribution rather than an orbit. In the figure, the shading indicates the relative probability to "find" the electron, having the energy corresponding to the given quantum numbers, at that point. De Broglie's prediction of a wave nature for electrons led Erwin Schrödinger to postulate a wave equation for electrons moving under the influence of the nucleus in the atom.
The earliest direct observation of interaction between meteors and radio propagation was reported in 1929 by Hantaro Nagaoka of Japan. In 1931, Greenleaf Pickard noticed that bursts of long distance propagation occurred at times of major meteor showers. At the same time, Bell Labs researcher A. M. Skellett was studying ways to improve night-time radio propagation, and suggested that the oddities many researchers were seeing were due to meteors. The next year Schafer and Goodall noted that the atmosphere was disturbed during that year's Leonid meteor shower, prompting Skellett to postulate that the mechanism was reflection or scattering from electrons in meteor trails.
In 2016, Cheung claimed to have written "1,500 articles and 20 books in Chinese" during his academic career. He obtained his PhD in economics from UCLA, where his teachers were the American economists Armen Alchian and Jack Hirshleifer. He taught in the Department of Economics at the University of Washington from 1969 to 1982, and then at the University of Hong Kong from 1982 to 2000. During this period, Cheung reformed the syllabus of Hong Kong's A-level Economics examination, adding the concepts of the postulate of constrained maximization, methodology, transaction cost and property right, most of which originate from the theories of the Chicago school.
Safford Unified School District v. Redding illustrates his application of this postulate in the Fourth Amendment context. School officials in the Safford case had a reasonable suspicion that 13-year- old Savana Redding was illegally distributing prescription-only drugs. All the justices concurred that it was therefore reasonable for the school officials to search Redding, and the main issue before the court was only whether the search went too far by becoming a strip search or the like.Safford Unified School District v. Redding, 557 U. S. __ (2009). Full text of opinion courtesy of Findlaw.com. All of the justices, except Thomas, concluded that this search violated the Fourth Amendment.
In fact, though many scholars believe that the name of Sobek, Sbk, is derived from s-bAk, "to impregnate", others postulate that it is a participial form of the verb sbq, an alternative writing of sAq, "to unite", thereby meaning Sbk could roughly translate to "he who unites (the dismembered limbs of Osiris)". It is from this association with healing that Sobek was considered a protective deity. His fierceness was able to ward off evil while simultaneously defending the innocent. He was thus made a subject of personal piety and a common recipient of votive offerings, particularly in the later periods of ancient Egyptian history.
According to Sidney Drell and Ambassador James Goodby, "It takes an extraordinary flight of imagination to postulate a modern new arsenal composed of such untested designs that would be more reliable, safe and effective than the current U.S. arsenal based on more than 1,000 tests since 1945".Drell_Goodby_fnl.indd Critics maintain that this innocuous-sounding program could significantly damage US national security. Critics believe an expansive RRW program would anger US allies as well as hostile nations. They worry it would disrupt the global cooperation in nonproliferation that is vital to diplomacy with emerging nuclear powers such as Iran and North Korea and to controlling clandestine trafficking in nuclear materials and equipment.
This led Stroun to explore if other methods could be developed to not only detect the overall abundance of nucleic acids in patients with disease (and specifically cancer) but to also detect the disease-specific components of such circulating nucleic acids themselves. Unlike bacterial transformations in plants and animal cells involving clear transfer of separately identifiable nucleic acids, it was not clear how malignancy in cancer arose, although there were many competing theories. Stroun’s postulate that neoplastic malignancy was associated with the presence of tumor specific nucleic acids, led to extensive research by his group of circulating nucleic acids in cancer patients in the late 1980s.
Attempts have also been made to put elements of the above models into a kind of meta- model. Based on a theorized blindness of a single perspective, Lee Bolman and Terrence Deal have designed a model that splits analysis into four distinct paradigms. These 'frames' are to be used as a pluralistic model, and therefore allow analysts and leaders to change their thinking by re-framing understanding and points of reference. Bolman and Deal postulate that re- framing is a powerful way to think about situations in multiple ways, which is why taking a meta-model approach enables the development of alternative diagnoses and strategies.
The Institute for Telecommunication Sciences (ITS) performs the research and engineering that enables the U.S. Government, national and international standards organizations, and many aspects of private industry to manage the radio spectrum and ensure that innovative, new technologies are recognized and effective. Past experience, current knowledge, and facilities allow the institute to solve complex telecommunications problems, as well as visually postulate the significant needs for the future. ITS is notable for pioneering work on radio wave propagation, development of measurement methods to characterize complex signals, and predict end-to-end system performance. This government entity also provides research and engineering that is critical to continued U.S. leadership in telecommunications technology. (Dept.
Solidarity was an egalitarian and collectivist movement. It did not postulate any re-privatization of property taken over by the state after World War II or of rural possessions generated by the land reform, as such concepts were beyond the axiological horizon of Polish society. Solidarity was socialist and social justice was its goal. The First Solidarity upheaval could be viewed also as working people revolting against the emerging capitalist features of the economic order that diminished their role in Gierek-led society, combined with the "anti-politics" approach (building civil society "without reference to both state and market") embraced at that time by their allied intellectual leaders.
So it was Poincaré who, on 5 June 1905,Poincaré (1905b) who introduced the so-called "Poincaré stresses" to solve that problem. Those stresses were interpreted by him as an external, non-electromagnetic pressure, which stabilize the electrons and also served as an explanation for length contraction.Janssen/Mecklenburg (2007) Although he argued that Lorentz succeeded in creating a theory which complies to the postulate of relativity, he showed that Lorentz's equations of electrodynamics were not fully Lorentz covariant. So by pointing out the group characteristics of the transformation, Poincaré demonstrated the Lorentz covariance of the Maxwell–Lorentz equations and corrected Lorentz's transformation formulae for charge density and current density.
One theory of interactional linguistics, emergent grammar, proposed by Paul Hopper, postulates that rules of grammar come about as language is spoken and used. This is contrary to the a priori grammar postulate, the idea that grammar rules exist in the mind before the production of utterances. Compared to the principles of generative grammar and the concept of Universal Grammar, interactional linguistics asserts that grammar emerges from social interaction. Whereas Universal Grammar claims that features of grammar are innate, emergent grammar and other interactional theories claim that the human language faculty has no innate grammar and that features of grammar are learned through experience and social interaction.
This is controversial because it violates a core precept of modern physics--that, in principle, the value of a wave function of a physical system at one point in time should determine its value at any other time. A fundamental postulate of the Copenhagen interpretation of quantum mechanics is that complete information about a system is encoded in its wave function up to when the wave function collapses. The evolution of the wave function is determined by a unitary operator, and unitarity implies that information is conserved in the quantum sense. As of November 2019, the paradox may have been resolved, at least for simplified models of gravity (see § Recent developments).
Both the Human fleet and the rebel Cylons are disillusioned after finding Earth devastated by a nuclear holocaust, which occurred at least 2,000 years prior to the events of the episode. After research on the bodies found in the soil, the Cylons and Dr. Baltar (James Callis) conclude the remains are not human, but Cylon in origin. The rebel Cylons further state the mechanical Cylon remains resemble older Centurions of theirs, but are of a kind unknown to them. Following this, they postulate that the thirteenth tribe consisted of a different kind of Cylon which existed over 2,000 years ago and moved out from Kobol to populate Earth.
Absolute geometry is a geometry based on an axiom system for Euclidean geometry without the parallel postulate or any of its alternatives. Traditionally, this has meant using only the first four of Euclid's postulates, but since these are not sufficient as a basis of Euclidean geometry, other systems, such as Hilbert's axioms without the parallel axiom, are used. The term was introduced by János Bolyai in 1832.In "Appendix exhibiting the absolute science of space: independent of the truth or falsity of Euclid's Axiom XI (by no means previously decided)" It is sometimes referred to as neutral geometry,Greenberg cites W. Prenowitz and M. Jordan (Greenberg, p.
W.E.B. Du Bois attended the conference and was put in charge of drafting the general report. After the conference, 5 panafrican congresses were held in the 20th century which eventually led to the creation of the African Union. Firmin was invested in the three main elements of Pan-Africanist thought: the rejection of the postulate of race inequality, proof that Africans were capable of civilization, and examples of successful Africans producing knowledge in diverse fields. In looking to move away from the biological understanding of race, Firmin's scientific approach was informed by the idea of a Black Egypt as the source of Greek civilization.
The picture shows exterior angles along with interior ones, for the rightmost vertex it is shown as Angles between adjacent sides of a triangle are referred to as interior angles in Euclidean and other geometries. Exterior angles can be also defined, and the Euclidean triangle postulate can be formulated as the exterior angle theorem. One can also consider the sum of all three exterior angles, that equals to 360°From the definition of an exterior angle, its sums up to the straight angle with the interior angles. So, the sum of three exterior angles added to the sum of three interior angles always gives three straight angles.
All these can be considered as applications of the Zeno effect. By its nature, the effect appears only in systems with distinguishable quantum states, and hence is inapplicable to classical phenomena and macroscopic bodies. The mathematician Robin Gandy recalled Turing's formulation of the quantum Zeno effect in a letter to fellow mathematician Max Newman, shortly after Turing's death: As a result of Turing's suggestion, the quantum Zeno effect is also sometimes known as the Turing paradox. The idea is implicit in the early work of John von Neumann on the mathematical foundations of quantum mechanics, and in particular the rule sometimes called the reduction postulate.
Where the goal of Dianetics is to rid the individual of his reactive mind engrams, the stated goal of Scientology is to rehabilitate the individual's spiritual nature so that he may reach his full potential. In 1978, Hubbard released New Era Dianetics (NED), a revised version supposed to produce better results in a shorter period of time. The course consists of 11 rundowns and requires a specifically trained auditor. It is run (processed) exactly like Standard Dianetics (once very widely practiced before the advent of NED) except the pre-clear (parishioner) is encouraged to find the "postulate" he made as a result of the incident.
Students' aspirations to pursue careers in mathematics and science influence both the courses they choose to take in those areas and the level of effort they put forth in these courses. A 1996 USA study suggested girls begin to lose self-confidence in middle school because they believe that men possess more intelligence in technological fields. The fact that men outperform women in spatial analysis, a skillset many engineering professionals deem vital, generates this misconception. Feminist scholars postulate that boys are more likely to gain spatial skills outside the classroom because they are culturally and socially encouraged to build and work with their hands.
Not only did Corey see the images at the time, but Pauling himself regained his passport within a few weeks and toured English laboratories well before writing his DNA paper. He had ample opportunity to visit Franklin's lab and see her work, but chose not to. Pauling also studied enzyme reactions and was among the first to point out that enzymes bring about reactions by stabilizing the transition state of the reaction, a view which is central to understanding their mechanism of action. He was also among the first scientists to postulate that the binding of antibodies to antigens would be due to a complementarity between their structures.
A diagram showing the ecological processes of coral reefs before and after the Anthropocene The abundance of species extinctions considered anthropogenic, or due to human activity, has sometimes (especially when referring to hypothesized future events) been collectively called the "Anthropocene extinction". "Anthropocene" is a term introduced in 2000. Some now postulate that a new geological epoch has begun, with the most abrupt and widespread extinction of species since the Cretaceous–Paleogene extinction event 66 million years ago. The term "anthropocene" is being used more frequently by scientists, and some commentators may refer to the current and projected future extinctions as part of a longer Holocene extinction.
Those who take anthropological humanism seriously tend to embrace a humanistic ethos and those who reject humanistic principles of agency tend to fight against anthropological humanism, expressed in different forms: social Darwinism, racism, reductionist naturalism, chauvinist nationalism, discriminating sexism and other forms of anti-humanism. Since communication plays a central role in this form of humanism, Nida-Rümelin presented an account of humanistic semantics. Nida-Rümelin defends a basic, non- ontological, non-metaphysical realism against instrumentalism in the philosophy of science, positivism, and post-modernism in practical philosophy, the humanities and the social sciences. Realism is not a metaphysical postulate but it is part of our everyday practice of giving and taking reasons (form of life).
This iconographic type – very often represented among the Nuragic bronze figurines – has been reported only twice among the Mont'e Prama statues, plus a third possible case, of which only one is in a good state of preservation. However, a reassembled shield, not assigned to any of the former three specimens, and numerous other fragments of a shield and (possibly) of a torso, suggest that the number of warriors was larger. Initially, the fragments of round-shaped shields had been attributed to archers, but later the hilt of a sword and similarities of the shields geometrical patterns to those of some bronzetti, led to postulate the presence of one or more statues of warriors.
In Chapters 2 and 3, MacArthur and Wilson postulate that insular species richness depends on island size and isolation from source regions. The authors present an equilibrium model that is based on the following concept: when there is an addition of the number of species on an island, the island's immigration rate of new species will decrease while the extinction rate of resident species will increase. MacArthur and Wilson thus assume that there will be an equilibrial point where the immigration rate equals the extinction rate. They further hypothesize that an increase in island size will lower extinction curves while a decrease in distance between the island and the source region will raise immigration curves.
Just like the preceding Postulate Sejm, the Estates had very limited competences: they met to hear the Emperor decrees, distribute tax assessments, grant Galician titles of nobility to individuals who already held similar titles elsewhere in the Austrian Empire, prepare petitions and appeals to be heard by the Emperor. Polish 19th-century historian, Henryk Schmitt, wrote that the role of the Estates was to listen to the government decisions, and file petitions, which often waited for the royal reply for several years; he thus notes that the Estates were powerless, a "comedy", their only purpose being to fulfill the Congress of Vienna requirement of having some form of "national representation" on the lands of the Austrian partition.
8 Since that time, developments in human evolutionary genetics and physical anthropology have led to a new consensus among anthropologists that human race is a sociopolitical phenomenon rather than a biological one. The term scientific racism is generally used pejoratively when applied to more modern theories, such as those in The Bell Curve (1994). Critics argue that such works postulate racist conclusions, such as a genetic connection between race and intelligence, that are unsupported by available evidence. Publications such as the Mankind Quarterly, founded explicitly as a "race-conscious" journal, are generally regarded as platforms of scientific racism because they publish fringe interpretations of human evolution, intelligence, ethnography, language, mythology, archaeology, and race.
The aufbau principle rests on a fundamental postulate that the order of orbital energies is fixed, both for a given element and between different elements; in both cases this is only approximately true. It considers atomic orbitals as "boxes" of fixed energy into which can be placed two electrons and no more. However, the energy of an electron "in" an atomic orbital depends on the energies of all the other electrons of the atom (or ion, or molecule, etc.). There are no "one-electron solutions" for systems of more than one electron, only a set of many-electron solutions that cannot be calculated exactlyElectrons are identical particles, a fact that is sometimes referred to as "indistinguishability of electrons".
The resource-utilization approach consists in postulating that not only competition can occur, but also that it does occur, and that overlap in resource utilization directly enables the estimation of the competition coefficients. This postulate, however, can be misguided, as it ignores the impacts that the resources of each category have on the organism and the impacts that the organism has on the resources of each category. For instance, the resource in the overlap region can be non-limiting, in which case there is no competition for this resource despite niche overlap. As a hemi-parasitic plant, the mistletoe in this tree exploits its host for nutrients and as a place to grow.
Much of the formal study of QFT is devoted to the properties of the resulting functional integral, and much effort (not yet entirely successful) has been made toward making these functional integrals mathematically precise. Such a functional integral is extremely similar to the partition function in statistical mechanics. Indeed, it is sometimes called a partition function, and the two are essentially mathematically identical except for the factor of in the exponent in Feynman's postulate 3. Analytically continuing the integral to an imaginary time variable (called a Wick rotation) makes the functional integral even more like a statistical partition function and also tames some of the mathematical difficulties of working with these integrals.
Blatz rejected Freudian theories of psychology; he asserted that "it is not necessary to postulate an unconscious." During his academic career, he also stated that some children might be better educated by studying music rather than reading, writing and arithmetic and defended the practice of teaching children to believe in Santa Claus. Security theory Blatz postulated security as the primary goal of the human being, but conceptualized security not as safety—a static state that is subject to crisis and hence an insecure state—but as a dynamic state. Security was for him a state of mind, characterized by serenity, which grew out of trust in one's ability to deal with the future.
All the work related to the Parallel Postulate revealed that it was quite difficult for a geometer to separate his logical reasoning from his intuitive understanding of physical space, and, moreover, revealed the critical importance of doing so. Careful examination had uncovered some logical inadequacies in Euclid's reasoning, and some unstated geometric principles to which Euclid sometimes appealed. This critique paralleled the crisis occurring in calculus and analysis regarding the meaning of infinite processes such as convergence and continuity. In geometry, there was a clear need for a new set of axioms, which would be complete, and which in no way relied on pictures we draw or on our intuition of space.
The Pythagorean theorem is derived from the axioms of Euclidean geometry, and in fact, were the Pythagorean theorem to fail for some right triangle, then the plane in which this triangle is contained cannot be Euclidean. More precisely, the Pythagorean theorem implies, and is implied by, Euclid's Parallel (Fifth) Postulate. Thus, right triangles in a non-Euclidean geometry do not satisfy the Pythagorean theorem. For example, in spherical geometry, all three sides of the right triangle (say a, b, and c) bounding an octant of the unit sphere have length equal to /2, and all its angles are right angles, which violates the Pythagorean theorem because a^2 + b^2 = 2 c^2 > c^2 .
Continuous areas and narrow filaments of light-gray ejecta extend from the crater across the dark mare surface through 270°, but are entirely absent in the southern 90° sector. Within the crater, dark material occurs on the southern crater wall while the remaining walls are bright. This crater probably resulted from the impact of a projectile traveling from south to north along an oblique trajectory. Its pattern of ejecta distribution is similar to that of small craters produced by the impact of missiles along oblique trajectories at the White Sands Missile Range, NM. Some observers postulate that the dark material is a talus deposit of mare material that has fallen into the crater.
Three-dimensional drawing of the Viking sundial (stamp illustration) with a conical vertical gnomon and its shadow, the endpoint of which touches the hyperbola scratched into the horizontal wooden disc During the Viking Age (900-1200 AD) Vikings were the dominant seafarers of the North Atlantic. One of the keys to their success was the ability to navigate skillfully across the open waters. The Vikings were experts in judging speed and wind direction, and in knowing the current and when to expect high and low tides. Viking navigational techniques are not well understood, but historians postulate that the Vikings probably had some sort of primitive astrolabe and used the stars to plot their course.
Hannes Alfvén suggested that scaling laboratory results can be extrapolated up to the scale of the universe. A scaling jump by a factor 109 was required to extrapolate to the magnetosphere, a second jump to extrapolate to galactic conditions, and a third jump to extrapolate to the Hubble distance. Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe beyond the Solar System. recount: It was described as this in the February 1992 issue of Sky & Telescope ("Plasma Cosmology"), and by Anthony Peratt in the 1980s, who describes it as a "nonstandard picture".
Charles Alfred Coulson (1955) Science and Christian Belief, p 20. According to John Habgood in The Westminster Dictionary of Christian Theology, the phrase is generally derogatory, and is inherently a direct criticism of a tendency to postulate acts of God to explain phenomena for which science has yet to give a satisfactory account.The Westminster Dictionary of Christian Theology (Ed. Alan Richardson, John Bowden, 1983), p 242 Habgood also states: > It is theologically more satisfactory to look for evidence of God's actions > within natural processes rather than apart from them, in much the same way > that the meaning of a book transcends, but is not independent of, the paper > and ink of which it is comprised.
Spatial dependence is the spatial relationship of variable values (for themes defined over space, such as rainfall) or locations (for themes defined as objects, such as cities). Spatial dependence is measured as the existence of statistical dependence in a collection of random variables, each of which is associated with a different geographical location. Spatial dependence is of importance in applications where it is reasonable to postulate the existence of corresponding set of random variables at locations that have not been included in a sample. Thus rainfall may be measured at a set of rain gauge locations, and such measurements can be considered as outcomes of random variables, but rainfall clearly occurs at other locations and would again be random.
They grow root crops in forest clearings (slash and burn farms), and hunt wild animals in the forest for their meat needs. There are no authentic documents in existence explaining the original stock of the Mangyan people, but later theoreticians postulate that they migrated from Indonesia before 775 A.D. They hopped from island to island, until finally settling down permanently in Mindoro. It appeared that clan settlements existed in the North as well as in the southern ends of the island. By 779, the southwest coast of the island was already a known trading center, and its fine natural harbor frequented by Arab, Indian and Chinese maritime traders who plied the route.
The western nations respond with biological warfare and bombard China with dozens of the most infectious diseases. On his fears about China, he admits, "it must be taken into consideration that the above postulate is itself a product of Western race-egotism, urged by our belief in our own righteousness and fostered by a faith in ourselves which may be as erroneous as are most fond race fancies." By contrast, many of London's short stories are notable for their empathetic portrayal of Mexican ("The Mexican"), Asian ("The Chinago"), and Hawaiian ("Koolau the Leper") characters. London's war correspondence from the Russo-Japanese War, as well as his unfinished novel Cherry, show he admired much about Japanese customs and capabilities.
Taurinus corresponded with his uncle Ferdinand Karl Schweikart (1780-1859), who was a law professor in Königsberg, among other things about mathematics. Schweikart examined a model (after Giovanni Girolamo Saccheri and Johann Heinrich Lambert) in which the parallel postulate is not satisfied, and in which the sum of three angles of a triangle is less than two right angles (which is now called hyperbolic geometry). While Schweikart never published his work (which he called "astral geometry"), he sent a short summary of its main principles by letter to Carl Friedrich Gauß. Motivated by the work of Schweikart, Taurinus examined the model of geometry on a "sphere" of imaginary radius, which he called "logarithmic-spherical" (now called hyperbolic geometry).
Guillaume-Jules Hoüel (7 April 1823 – 14 June 1886) was a French mathematician. He entered the École Normale Supérieure in 1843 and received his doctoral degree in 1855 from the Sorbonne. He was sought by Urbain Le Verrier at the Paris Observatory, but chose instead to return to Thaon to study there. In 1859 he began to teach at Bordeaux. In 1863 Hoüel expressed his doubts about the verifiability of the parallel postulate of Euclid.J. Houel (1863) "Essai d'une expositin rationelle des principes fondamentaux de la geometrie elementaire", Archiv der Mathematik und Physik 40: 171–211 In 1867 Hoüel produced French translations of two key publications of non- Euclidean geometry: Lobachevski's Geometrical Studies on the Theory of ParallelsJ.
It can also be asserted that this whole legal system was ideologically founded on the indigenous postulate which adhered to the shamanistic religio-political belief in polytheistic gods and which was called kamiTranslation of "kami" = gods in Shintoism, not only enshrined in Jinja (enshrinement of Shinto gods, worshiped by any group of small local fraternities, local communities or associated believers from different localities) but also deified as governing human affairs and natural occurrences, as cited by Masaji Chiba, "Japan" Poh-Ling Tan, (ed), Asian Legal Systems, Butterworths, London, 1997 at 118. and later developed into Shintoism.Masaji Chiba, "Japan" Poh-Ling Tan, (ed), Asian Legal Systems, Butterworths, London, 1997 at 91. Two qualifications can be added to these assertions.
In thermochemistry, the Thomsen–Berthelot principle is a hypothesis in the history of chemistry which argued that all chemical changes are accompanied by the production of heat and that processes which occur will be ones in which the most heat is produced. This principle was formulated in slightly different versions by the Danish chemist Julius Thomsen in 1854 and by the French chemist Marcellin Berthelot in 1864. This early postulate in classical thermochemistry became the controversial foundation of a research program that would last three decades. This principle came to be associated with what was called the thermal theory of affinity, which postulated that the heat evolved in a chemical reaction was the true measure of its affinity.
For example, exploring the quantum problem of wave-particle duality, one of the central mysteries of quantum theory, the author claims that "in terms of the Invariant Set Postulate, the paradox is easily resolved, in principle at least". The paper and related talks given at the Perimeter Institute and University of Oxford also explores the role of gravity in quantum physics.Palmer, T. N. (21 October 2008) “Hawking Boxes and Invariant Sets - A New Look at the Foundations of Quantum Theory and the Associated Role of Gravity”. Perimeter Institute. PIRSA:08100022.Palmer, T. N. (April 2009) “The invariant set hypothesis: a new geometric framework for the foundations of quantum theory and the role played by gravity”.
If all five points are collinear, then the remaining line is free, which leaves 2 parameters free. Given four points in general linear position (no three collinear; in particular, no two coincident), there are exactly three pairs of lines (degenerate conics) passing through them, which will in general be intersecting, unless the points form a trapezoid (one pair is parallel) or a parallelogram (two pairs are parallel). Given three points, if they are non- collinear, there are three pairs of parallel lines passing through them – choose two to define one line, and the third for the parallel line to pass through, by the parallel postulate. Given two distinct points, there is a unique double line through them.
George E. G. Catlin (1938, 1964 edition), p. 45 Ashley Ornstein has alleged, in a consumer textbook published by Pearson Education, that accounts of Durkheim's positivism are possibly exaggerated and oversimplified; Comte was the only major sociological thinker to postulate that the social realm may be subject to scientific analysis in exactly the same way as natural science, whereas Durkheim saw a far greater need for a distinctly sociological scientific methodology. His lifework was fundamental in the establishment of practical social research as we know it today—techniques which continue beyond sociology and form the methodological basis of other social sciences, such as political science, as well of market research and other fields.
Watercolor of a Secotan village, by John White People have considered the possibility that the missing colonists could have assimilated into nearby Native American tribes since at least 1605. If this integration was successful, the assimilated colonists would gradually exhaust their European supplies (ammunition, clothing) and discard European culture (language, style of dress, agriculture) as Algonquian lifestyle became more convenient. Colonial era Europeans observed that many people removed from European society by Native Americans for substantial periods of time—even if captured or enslaved—were reluctant to return; the reverse was seldom true. Therefore, it is reasonable to postulate that, if the colonists were assimilated, they or their descendants would not seek reintegration with subsequent English settlers.
Most models of the neural control of stiffness promote the idea that humans choose an optimal limb stiffness based on their environment or the task at hand. Studies postulate the humans do this in order to stabilize unstable dynamics of the environment and also to maximize the energy efficiency of a given movement. The exact method by which humans accomplish this is unknown, but impedance control has been used to give insight into how humans may choose an appropriate stiffness in different environments and as they perform different tasks. Impedance control has served as the basis for much of the work done in the area of determining how humans interact with their environment.
At 16 meters above the level of the surrounding surface, its height allowed the king more privacy to hold ceremonies, which could only be viewed by a select few. Schele and FreidelSchele & Freidel 1990:118 postulate that the existence of such a pyramid, with its differentiated viewing spaces, indicates a high degree of social stratification among the people of Cerros. This triadic plan was a hallmark at major Preclassic centers and it appears that by emulating this architectural plan, the rulers of Cerros had embraced a further means of reinforcing a basic cosmological principle underlying their power.Sharer & Traxler 2005: 267 This temple was probably constructed upon the accession of a new king.
Lederer, M., 1978, 1981. See under Publications. We all experience deverbalization in everyday communication: we keep in mind facts, notions, events conveyed by words, but we do not retain these words in our memory. The ITT found support for this postulate in neuropsychology, which suggests that language and thought are located in different areas in the brain.Barbizet, J., Etudes sur la mémoire, deuxième série, Paris : L’Expansion scientifique française, 1966.

Physical organic chemists use the mathematical foundation of chemical kinetics to study the rates of reactions and reaction mechanisms. Unlike thermodynamics, which is concerned with the relative stabilities of the products and reactants (ΔG°) and their equilibrium concentrations, the study of kinetics focuses on the free energy of activation (ΔG‡) -- the difference in free energy between the reactant structure and the transition state structure—of a reaction, and therefore allows a chemist to study the process of equilibration. Mathematically derived formalisms such as the Hammond Postulate, the Curtin-Hammett principle, and the theory of microscopic reversibility are often applied to organic chemistry. Chemists have also used the principle of thermodynamic versus kinetic control to influence reaction products.
Hansen began quietly purchasing available land near Safeco Field in Seattle's SoDo industrial neighborhood, at the southern end of what was designated a Stadium Transition Overlay District housing both Safeco Field home of the MLB's Seattle Mariners and CenturyLink Field home of the NFL's Seattle Seahawks and MLS's Seattle Sounders. A short time later, Hansen presented to McGinn and King County Executive Dow Constantine the proposal for a basketball, hockey, and entertainment arena at the SoDo site. McGinn employed a stadium consultant on the city's behalf to study the viability of such a project. Local media took notice of the land purchases and began to postulate that it was for an arena.
Different dialects of Arabic Colloquial Arabic is a collective term for the spoken dialects of Arabic used throughout the Arab world, which differ radically from the literary language. The main dialectal division is between the varieties within and outside of the Arabian peninsula, followed by that between sedentary varieties and the much more conservative Bedouin varieties. All the varieties outside of the Arabian peninsula (which include the large majority of speakers) have many features in common with each other that are not found in Classical Arabic. This has led researchers to postulate the existence of a prestige koine dialect in the one or two centuries immediately following the Arab conquest, whose features eventually spread to all newly conquered areas.
Wanniski was instrumental in popularizing the ideas of lower tax rates embodied in the "Laffer Curve" and was present in 1974 when Arthur Laffer drew the curve on the famous napkin for Dick Cheney and Donald Rumsfeld. A simplified view of the theory is that tax revenues would be zero if tax rates were either 0% or 100% and somewhere in between 0% and 100% is a tax rate that maximizes total revenue. Laffer's postulate was that the tax rate that maximizes revenue was at a much lower level than previously believed, so low that current tax rates were above the level for revenue to be maximized. Many economists are skeptical that it was then true, in practice.
A map showing the outline of those parts now adjacent to the traditional county of Essex (in grey), but which historians postulate were part of the ancient Kingdom of Essex before becoming detached during the middle of the 8th century. The kingdom was bounded to the north by the River Stour and the Kingdom of East Anglia, to the south by the River Thames and Kent, to the east lay the North Sea and to the west Mercia. The territory included the remains of two provincial Roman capitals, Colchester and London. The early kingdom included the land of the Middle Saxons, later Middlesex, most if not all of Hertfordshire and may at times have included Surrey.
The first sense of the term is the geometry over a non-Archimedean ordered field, or a subset thereof. The aforementioned Dehn plane takes the self-product of the finite portion of a certain non-Archimedean ordered field based on the field of rational functions. In this geometry, there are significant differences from Euclidean geometry; in particular, there are infinitely many parallels to a straight line through a point—so the parallel postulate fails—but the sum of the angles of a triangle is still a straight angle. Intuitively, in such a space, the points on a line cannot be described by the real numbers or a subset thereof, and there exist segments of "infinite" or "infinitesimal" length.
The episodes on Blu-ray are all in remastered surround sound, whereas the DVD version had stereo. Two of the main cast, Sheldon and Leonard, are named after actor, director, and producer Sheldon Leonard. Johnny Galecki and Sara Gilbert both selected the episode "The Hamburger Postulate" as a Primetime Emmy Award submission for Outstanding Lead Actor in a Comedy Series and Outstanding Guest Actress in a Comedy Series, respectively, at the 60th Primetime Emmy Awards, but both ended up not receiving a nomination. Jim Parsons selected the episode "The Pancake Batter Anomaly" as a Primetime Emmy Award submission for Outstanding Lead Actor in a Comedy Series at the 60th Primetime Emmy Awards, but ended up not receiving a nomination.
Collins & Hawking (1973) characterized Carter's then-unpublished big idea as the postulate that "there is not one universe but a whole infinite ensemble of universes with all possible initial conditions". If this is granted, the anthropic principle provides a plausible explanation for the fine tuning of our universe: the "typical" universe is not fine-tuned, but given enough universes, a small fraction will be capable of supporting intelligent life. Ours must be one of these, and so the observed fine tuning should be no cause for wonder. Although philosophers have discussed related concepts for centuries, in the early 1970s the only genuine physical theory yielding a multiverse of sorts was the many- worlds interpretation of quantum mechanics.
The term itself is an Early Modern English spelling for magic, used in works such as the 1651 translation of Heinrich Cornelius Agrippa's De Occulta Philosophia, Three Books of Occult Philosophy, or Of Magick. Aleister Crowley chose the spelling to differentiate his practices and rituals from stage magic (which may be more appropriately termed “illusion”) and the term has since been re-popularised by those who have adopted elements of his teachings. Crowley defined Magick as "the science and art of causing change to occur in conformity with will."Magick in Theory and Practice, Book 3 of 4 by Aleister Crowley He goes on to elaborate on this, in one postulate, and twenty eight theorems.
In these terms, the Schrödinger equation is an instance of the Born rule applied to the passing of time; an agent uses it to relate how she will gamble on informationally complete measurements potentially performed at different times. Those QBists who find this approach promising are pursuing a complete reconstruction of quantum theory featuring the urgleichung as the key postulate. (The urgleichung has also been discussed in the context of category theory.) Comparisons between this approach and others not associated with QBism (or indeed with any particular interpretation) can be found in a book chapter by Fuchs and Stacey and an article by Appleby et al. As of 2017, alternative QBist reconstruction efforts are in the beginning stages.
Until experimental proof of atoms was later provided in the 20th century, the atomic theory was driven largely by philosophical considerations and scientific intuition. The 5th century BC Greek philosopher Parmenides, in his only known work, a poem conventionally titled On Nature, uses verbal reasoning to postulate that a void, essentially what is now known as a vacuum, in nature could not occur. This view was supported by the arguments of Aristotle, but was criticized by Leucippus and Hero of Alexandria. From antiquity to the Middle Ages various arguments were put forward to prove or disapprove the existence of a vacuum and several attempts were made to construct a vacuum but all proved unsuccessful.
At the same time, he also quoted Otto Betz's 1968 opinion that in recent years "no serious scholar has ventured to postulate the non-historicity of Jesus—or at any rate very few, and they have not succeeded in disposing of the much stronger, indeed very abundant, evidence to the contrary".Betz, Otto, What Do We Know About Jesus? (SCM-Canterbury Press, 1968) p. 9. In the same book, he also wrote: Graeme Clarke, Emeritus Professor of Classical Ancient History and Archaeology at Australian National University stated in 2008: "Frankly, I know of no ancient historian or biblical historian who would have a twinge of doubt about the existence of a Jesus Christ—the documentary evidence is simply overwhelming".
Still others postulate that the number "three" is symbolic, meant to indicate a magnified karmic result for one's actions. Some people in the Goddess movement honor the Triple Goddess of Maiden, Mother, and Crone. The Maiden aspect of the Goddess is the archetype of a young woman or a child, representing independence and strength; the Mother aspect is the archetype of a nurturing mature woman; and the Crone aspect is the archetype of an old woman that represents wisdom, change, and transformation. Because the Crone aspect of the Goddess is understood by some to be destructive at times, some consider it to contain both positive and negative imagery and to present an ethical quandary.
A Lambert quadrilateral In geometry, a Lambert quadrilateral,the alternate name Ibn al-Haytham-Lambert quadrilateral, has been suggested in Boris Abramovich Rozenfelʹd (1988), A History of Non-Euclidean Geometry: Evolution of the Concept of a Geometric Space, p. 65. Springer, , in honor of Ibn al- Haytham named after Johann Heinrich Lambert, is a quadrilateral in which three of its angles are right angles. Historically, the fourth angle of a Lambert quadrilateral was of considerable interest since if it could be shown to be a right angle, then the Euclidean parallel postulate could be proved as a theorem. It is now known that the type of the fourth angle depends upon the geometry in which the quadrilateral exists.
For wavelength specificity, prior to Kirchhoff, the ratio was shown experimentally by Balfour Stewart to be the same for all bodies, but the universal value of the ratio had not been explicitly considered in its own right as a function of wavelength and temperature. Kirchhoff's original contribution to the physics of thermal radiation was his postulate of a perfect black body radiating and absorbing thermal radiation in an enclosure opaque to thermal radiation and with walls that absorb at all wavelengths. Kirchhoff's perfect black body absorbs all the radiation that falls upon it. Every such black body emits from its surface with a spectral radiance that Kirchhoff labeled (for specific intensity, the traditional name for spectral radiance).
For the 2010 ANZAC Test, Gallen was selected to play for Australia at lock forward in their victory against New Zealand. Gallen was left out of the first match of the State of Origin side but was selected for the two remaining matches. In the second game he was placed on report for a high shot on Nate Myles in the twenty-third minute. However, his performance was still impressive enough to lead Daily Telegraph Sports editor-at-large, New South Welshman Phil Rothfield, to postulate, that of all the NSW players, Gallen "possibly" would be the only one that Queensland would select if he was theoretically available for them (in place of Ashley Harrison).
Theories of automaticity postulate that more fluent language users can manage all of the components of language use without paying attention to each individual component of the act. In other words, fluency is achieved when one can access language knowledge and produce language unconsciously, or automatically. Theories that focus on speed or length and rate of speech typically expect fluent language users to produce language in real time without unusual pauses, false starts, or repetitions (recognizing that some presence of these elements are naturally part of speech). Fluency is sometimes considered to be a measure of performance rather than an indicator of more concrete language knowledge, and thus perception and understandability are often key ways that fluency is understood.
The apparent contradiction between Hawking's calculation and the unitarity postulate of quantum mechanics came to be known as the black hole information paradox.For an accessible introduction to the black hole information paradox, and the related scientific dispute between Hawking and Leonard Susskind, see Susskind 2008. The AdS/CFT correspondence resolves the black hole information paradox, at least to some extent, because it shows how a black hole can evolve in a manner consistent with quantum mechanics in some contexts. Indeed, one can consider black holes in the context of the AdS/CFT correspondence, and any such black hole corresponds to a configuration of particles on the boundary of anti-de Sitter space.
CHAPTER 17, THERE IS NO SUCH THING AS PUBLIC OPINION: This chapter delves into the workings of a majority rules system, and points out the contradictions and confusion of it all, ultimately stating that public opinion doesn't exist. It uses many examples to make its point, including different election statistics, the death sentence of a mentally retarded person, and a case with Justice Antonin Scalia. It also includes mathematical terms/concepts such as Independence of irrelevant alternatives, Asymmetric Domination effect, Australia's Single transferable vote, and Condorcet paradoxes. CHAPTER 18, “OUT OF NOTHING, I HAVE CREATED A STRANGE NEW UNIVERSE”: This chapter talks about János Bolyais, and his work on the parallel postulate.
Shannon, Michael Lynn; A Biography of L. Ron Hubbard. Hubbard referred to himself as a nuclear physicist on many occasions in the 1950s, such as in the tape-recorded 1956 lecture A Postulate Out of a Golden Age, where he not only claimed to be a nuclear physicist, but that he was offered (and turned down) a U.S. Government post as one. This comment has been edited out of the CD version of the lecture currently offered by the L. Ron Hubbard Classic Lectures series. In February 1966, Hubbard defended his mail-order degree: "I was a Ph.D., Sequoia's [sic] University and therefore a perfectly valid doctor under the laws of the State of California".
This third course was intended to show how different nations arrived at a belief in a soul, how they named its various faculties, and what they imagined about its fate after death. # Theosophy or Psychological Religion. The fourth and last course of lectures was intended to examine the relation between God and the soul ("these two Infinites"), including the ideas that some of the principal nations of the world have formed concerning this relation. Real religion, Müller asserted, is founded on a true perception of the relation of the soul to God and of God to the soul; Müller wanted to prove that this was true, not only as a postulate, but as an historical fact.
Both Smith and Ricardo deeply believed that price structures for products were determined by the law of value; but, Marx argued, neither of them could explain how that value-price relationship operated, without contradicting themselves. They could not theoretically reconcile the regulation of commodity trade by law of value, with profit- receipts in proportion to capital employed (rather than in proportion to labour-time worked).Friedrich Engels, Preface to Capital, Volume II, Penguin edition, p. 101. Smith and Ricardo mooted the concept of "natural prices" instead, to postulate a "natural" (intrinsic) self-balancing tendency of markets—at the point where demand and supply were balanced, the "natural" price (the "true" value) had been reached.
But Böhm- Bawerk said that what they missed was the process itself, the roundaboutness, which necessarily involves the passage of time. Roundabout processes, Böhm- Bawerk maintained, lead to a price that pays for more than labor value. This makes it unnecessary to postulate exploitation in order to understand the return on capital, although how the length of the production process in and of itself produces value remains unclear, as, if Böhm-Bawerk's idea were correct, the more inefficient a capitalist manufacturer, the longer their production process and the more profit they would accrue. When in fact the additional costs they incur through their inefficient production process would prevent them from selling their output at the market price.
Cardona's attempts to maintain that Latin forms like dixti are instances of haplology-as-regular-sound-change are ultimately sized up by Szemerényi as "mere postulate[s], contradicted by facts". Despite Szemerényi's differences with Cardona on the main thesis of his On Haplology in Indo-European, he commends the descriptions of Indian -yā́- forms (sections §§1-3) and Vedic -si- forms (section §5). Finally, Cardona's seminal work Pāṇini: His Work and Its Traditions, while generally praised for its lucidity, profundity, and comprehensiveness, has not entirely escaped critique. Hartmut Scharfe, for instance, criticizes Cardona heavily for his "excessive reliance" on the native Indian tradition and his consequent reluctance to break with tradition and adopt modern scholarship.
It might be imagined that absolute geometry is a rather weak system, but that is not the case. Indeed, in Euclid's Elements, the first 28 Propositions and Proposition 31 avoid using the parallel postulate, and therefore are valid in absolute geometry. One can also prove in absolute geometry the exterior angle theorem (an exterior angle of a triangle is larger than either of the remote angles), as well as the Saccheri–Legendre theorem, which states that the sum of the measures of the angles in a triangle has at most 180°.One sees the incompatibility of absolute geometry with elliptic geometry, because in the latter theory all triangles have angle sums greater than 180°.
The Great Goddess hypothesis theorizes that, in Palaeolithic, Mesolithic and/or Neolithic Europe and Western Asia and North Africa, a singular, monotheistic female deity was worshiped prior to the development of the polytheistic pagan religions of the Bronze Age and Iron Age. Having first been proposed as an idea relating to ancient Greek religion in 1849, it subsequently achieved some support amongst classicists. In the early 20th century, various historians began to postulate about the theory applying across Europe, and it was widely propagated by the archaeologist Marija Gimbutas in the 1980s. It has since been adopted by various feminist religious groups such as Dianic Wicca as a part of the mythology of their faith.
According to the first postulate of special relativity, all physical laws take their simplest form in an inertial frame, and there exist multiple inertial frames interrelated by uniform translation: This simplicity manifests in that inertial frames have self-contained physics without the need for external causes, while physics in non-inertial frames have external causes. The principle of simplicity can be used within Newtonian physics as well as in special relativity; see Nagel and also Blagojević. In practical terms, the equivalence of inertial reference frames means that scientists within a box moving uniformly cannot determine their absolute velocity by any experiment. Otherwise, the differences would set up an absolute standard reference frame.
Although never a Russian nationalist, Merezhkovsky was a Russo-centric author and thinker, cherishing the idea of his country's unique and in many ways decisive place in the world culture in history. Never tiring of reiterating the "Russian plight is the problem of the world, not Russia" postulate, he was ever on the look-out for some "strong leader" who would be able to organize and successfully see through the anti-Communist crusade. For a while Merezhkovsky thought he had found his hero in Benito Mussolini who, having sponsored his book on Dante, had several lengthy talks with the Russian writer on politics, literature and art. Impressed, Merezhkovsky started to see his new friend almost as an incarnation of Dante.
Several Chinese archaeologists postulate that Taosi was the site where the state of Youtang (有唐) being conquered by Emperor Yao, (traditionally c. 2356–2255 BC) who later instituted Taosi as the capital.尧的政治中心的迁移及其意义 In Chinese classic documents Yao Dian (Document of Yao) in Shang Shu (Book of Ancient Time), and Wudibenji (Records for the Five Kings) in Shiji (Historic Records), King Yao assigned astronomic officers to observe celestial phenomena, including time and position of sunrise, sunset, and stars in culmination, in order to systematically establish a solar calendar and a lunar calendar with 366 days a year with leap month. The observatory found at Taosi coincides with these records.
The entertainment from a Saunders Brothers Show comes as much from the humorous banter between the band members, audience members, and even the staff of the host establishment. The Brothers incorporate a great deal of humour into their show in the form of dialogues between (and during) songs, jokes, and non sequiturs. They are experts at gauging the interests and attitudes of given audiences and can subtly tailor every show to its complete entertainment potential, and some reviewers postulate this is why so many fans return for repeat shows. Wherever the venue, a Saunders Brothers Show can be very family-friendly yet offer a wink to subtle yet suggestive humour, intense entertainer/audience interaction, and a great deal of laughter.
These careful measurements were created to measure the differences in the speed of light in different directions. Michelson and Morley always found that the speed of light did not vary at all depending on the direction of measurement, or the position of the Earth in its orbit, deducing what we call a "null result" for their speed-of-light experiments. Neither he nor Michelson ever considered that these null results disproved the hypothesis of the existence of "luminiferous aether", in which electromagnetic waves were thought to be propagated. Their null results led the Irish physicist George Francis FitzGerald to postulate what we now call the FitzGerald–Lorentz contraction of physical objects in the direction of their movement in inertial frames of reference.
"Profile: Pasko Rakic", Nature Medicine 11, 362 (2005) This material has also provided evidence that contributed one of the significant tenets of Neuroscience, that neurons of the cerebral cortex last for the entire lifespan and are irreplaceable. This and other material, such as tissue from monkeys of different age, are available in MacBrainResource. Rakic discovered the early commitment of newborn neurons to their laminar, radial and areal fates and proposed differential cell adhesion as the basic mechanism for their surface- mediating migration along transient radial glial scaffolding. These studies led him to postulate the "radial unit hypothesis" and "protomap" hypotheses of cortical development and evolution that provide the framework for understanding basic principles of normal and pathological development of the human brain.
However, like non-human great apes, but unlike all previously recognized human ancestors, it had a grasping big toe adapted for locomotion in the trees (an arboreal lifestyle), though it was likely not as specialized for grasping as it is in modern great apes. Its tibial and tarsal lengths indicate a leaping ability similar to bonobos. It lacks any characters suggestive of specialized suspension, vertical climbing, or knuckle walking; and it seems to have used a method of locomotion unlike any modern great ape, which combined arboreal palm walking clambering and a form of bipedality more primitive than Australopithecus. The discovery of such unspecialized locomotion led American anthropologist Owen Lovejoy and colleagues to postulate that the chimpanzee–human last common ancestor used a similar method of locomotion.
Not every conjecture ends up being proven true or false. The continuum hypothesis, which tries to ascertain the relative cardinality of certain infinite sets, was eventually shown to be independent from the generally accepted set of Zermelo–Fraenkel axioms of set theory. It is therefore possible to adopt this statement, or its negation, as a new axiom in a consistent manner (much as Euclid's parallel postulate can be taken either as true or false in an axiomatic system for geometry). In this case, if a proof uses this statement, researchers will often look for a new proof that doesn't require the hypothesis (in the same way that it is desirable that statements in Euclidean geometry be proved using only the axioms of neutral geometry, i.e.
The crevalle jack inhabits both inshore and offshore waters to depths of around 350 m, predominantly over reefs, bays, lagoons and occasionally estuaries. Young fish dispersed north by currents in the eastern Atlantic are known to migrate back to more tropical waters before the onset of winter; however, if the fish fail to migrate, mass mortalities occur as the temperature falls below the species' tolerance. The crevalle jack is a powerful, predatory fish, with extensive studies showing the species consumes a variety of small fish, with invertebrates such as prawns, shrimps, crabs, molluscs and cephalopods also of minor importance. Dietary shifts with both age, location and season have been demonstrated, which led some researchers to postulate the species is indiscriminant in its feeding habits.
The Austrian economist Eugen von Böhm- Bawerk argued against both the Adam Smith labor theory of price and Marx's theory of exploitation. On the former, he contended that return on capital arises from the roundabout nature of production, which necessarily involves the passage of time. A steel ladder, for example, is produced and brought to market only if the demand supports the digging of iron ore, the smelting of steel, the machines that press that steel into ladder shape, the machines that make and help maintain those machines and so on. Roundabout processes, Böhm- Bawerk maintained, lead to a price that pays for more than labor value, and this makes it unnecessary to postulate exploitation to understand the return on capital.
As a second application of the proposed hypothesis, Ishiwara considered the problem of the photoelectric effect, obtaining a linear relationship between the electron energy and the radiation frequency in accordance with the Einstein formula. Later in the same year Ishiwara put forward another hypothesis, according to which the product of the energy of the atom and the period of electron motion in the stationary state should be equal to the integer number of Planck constants. In 1918, he linked the postulate proposed three years earlier to the theory of adiabatic invariants. Around the same time, analogous rules for quantizing systems of many degrees of freedom were independently obtained by William Wilson and Sommerfeld and are usually called the Sommerfeld quantum conditions.
Many contemporary cognitive theorists postulate models featuring a central pool "of mental resources that must be allocated to the various operations involved in processing, retaining, and reporting information". This means that working memory and the various areas of the brain responsible for it are theoretically limited to a finite set of "mental resources" or mental capacity with which to carry out operation. Cognitive inhibition, of course, is responsible for determining what is relevant to the working memory and shuts out what is irrelevant, "freeing up space" and mental capacity needed for more pressing matters. In the theory of inefficient inhibition, cognitive inhibition does not perform its function fully, and a shortage of mental resources leads to decreased performance or inefficiency in tasks that require more mental capacity.
His 1801 volume Disquisitiones Arithmeticae laid the foundations of modern number theory. Behavior of lines with a common perpendicular in each of the three types of geometry This century saw the development of the two forms of non-Euclidean geometry, where the parallel postulate of Euclidean geometry no longer holds. The Russian mathematician Nikolai Ivanovich Lobachevsky and his rival, the Hungarian mathematician János Bolyai, independently defined and studied hyperbolic geometry, where uniqueness of parallels no longer holds. In this geometry the sum of angles in a triangle add up to less than 180°. Elliptic geometry was developed later in the 19th century by the German mathematician Bernhard Riemann; here no parallel can be found and the angles in a triangle add up to more than 180°.
Using interactive experiments, he has worked on uncovering implicit musical systems and the way in which cultures build cognitive categories as attested in their music. His work is based on the postulate that, in order for it to be valid, data collected in the field must be corroborated by cognitive data specific to the holders of the culture studied. His research topics include the temporal organization of music, musical scales, polyphonic techniques, music in the social system and the elaboration of conceptual tools for the categorization, analysis and modeling of traditional music. From a mostly descriptive discipline, he has tried to build a science in the full sense of the word, with all of its attributes: experimentation, verification, validation, modeling, conceptualization and reconstitution by means of synthesis.
Donation Stela of Shebitku, with the cartouche identifying him (bottom left). Metropolitan Museum The Turin Stela 1467, which depicts Shabaka and Shebitku seated together (with Shebitku behind Shabaka) facing two other individuals across an offering table, was once considered to be clear evidence for a royal co-regency between these two Nubian kings in William J. Murnane's 1977 book on Ancient Egyptian Coregencies.William Murnane, Ancient Egyptian Coregencies, (SAOC 40: Chicago 1977), p.190 However, the Turin Museum has subsequently acknowledged the statue to be a forgery. Robert Morkot and Stephen Quirke, who analysed the stela in a 2001 article, also confirmed that the object is a forgery which cannot be used to postulate a possible coregency between Shabaka and Shebitku.
This means one must consider both wave and particle behavior of light on an equal footing. Wave–particle duality implies that one must A) use the unitary evolution of the wave before the observation and B) consider the particle aspect after the detection (this is called the Heisenberg–von Neumann collapse postulate). Indeed, since one could only observe the photon in one point of space (a photon can not be absorbed twice) this implies that the meaning of the wave function is essentially statistical and cannot be confused with a classical wave (such as those that occur in air or water). In this context the direct observation of a photon in the aperture plane precludes the following recording of the same photon in the focal plane (F).
This led the authors to postulate the existence of a temporary strain-transcending immunity: individuals were immune to reinfection with any other influenza strain for approximately six months following an infection. With this assumption, the agent-based model could reproduce the ladder-like phylogeny of influenza A/H3N2's HA protein. Work by Koelle and colleagues revisited the dynamics of influenza A/H3N2 evolution following the publication of a paper by Smith and colleagues which showed that the antigenic evolution of the virus occurred in a punctuated manner. The phylodynamic model designed by Koelle and coauthors argued that this pattern reflected a many-to-one genotype-to- phenotype mapping, with the possibility of strains from antigenically distinct clusters of influenza sharing a high degree of genetic similarity.
As pointed out above, long consonants did not exist in Proto-Indo-European, and many Germanic roots are attested with a long consonant in some of the ancient languages, but with a short one in others (often together with a short or a long vowel, respectively). This led the "Leiden School" to postulate that the Germanic roots with long plosives were not inherited from PIE, but borrowed from a substrate language. Kroonen (2011: 12) reported that his doctorate at the University of Leiden was originally intended > to investigate the influence of lost non-Indo-European languages on the > Proto-Germanic lexicon. [...] During the course of time, however, my > dissertation gradually developed into a study of the Proto-Germanic n-stems > and their typical morphology.
Crucially, this is the first demonstration of equilibration – the most important aspect of statistical mechanics – directly from first principles, without any additional assumptions. The result holds even in situations in which the standard assumptions of statistical mechanics do not apply, such as systems with strong long-range, non-screened interactions where temperature cannot even be defined. In an earlier work with Short and Winter he showed that the so-called equal a priori probability postulate, one of the basic postulates of statistical mechanics, is redundant, and is simply a consequence of typicality. (A similar proof is due to Goldstein et al.) With Yakir Aharonov and his group, Popescu discovered a number of quantum paradoxes, such as the quantum Cheshire Cat, and the quantum pigeonhole principle.
The sarcotesta and seeds remains buried for several weeks to become detoxified and consumable, the food product, known as querning, still contains toxins at the centre of the seeds. The distribution of the plant has been correlated to sites of long term human habitation, close to lakes or springs, and freshwater points at granitic outcrops of the kwongan, although the intervention of other consumers, birds and mammals, complicates a postulate that inadvertent or intentional cultivation is the primary factor in seed dispersal. Animals species involved in dispersal of the plant include birds such as the emu and mammalian species Trichosurus vulpecula, a common possum known locally as quumarl. The toxins macrozamin and cycasin are produced by cyanobacteria engaged in nitrogen fixing at their roots.
They respond well to applications of a general fertiliser, and favour full sun or partial shade. They are a recommended indoor plant, being tolerant of low light and temperature, slow growing and able to remain in a container indefinitely. The distribution of the zamia in the southwest has been correlated to sites of long term human habitation, close to lakes or springs, and freshwater points at granitic outcrops of the kwongan, although the intervention of other consumers, birds and mammals, complicates a postulate that inadvertent or intentional cultivation is the primary factor in seed dispersal. Animals species involved in dispersal of the plant include birds such as the emu and mammalian species Trichosurus vulpecula, a common possum known locally as quumarl.
Christian philosopher Alvin Plantinga argues that random chance, applied to a single and sole universe, only raises the question as to why this universe could be so "lucky" as to have precise conditions that support life at least at some place (the Earth) and time (within millions of years of the present). This fine-tuning of the universe is cited by philosopher and Christian apologist William Lane Craig as an evidence for the existence of God or some form of intelligence capable of manipulating (or designing) the basic physics that governs the universe. Craig argues, however, "that the postulate of a divine Designer does not settle for us the religious question."William Lane Craig, "The Teleological Argument and the Anthropic Principle". leaderu.
The difference in the response pattern of the LPC, in comparison with other components elicited in memory tasks, such as the N400, has played an important role in debates about dual-process theories of memory, which postulate qualitatively different mechanisms underlying familiarity and recollection. In terms of the neural source of the component, the characteristic scalp distribution of the LPC suggests that it might reflect neural activity generated in the lateral parietal cortex. Consistent with this hypothesis, fMRI studies report recollection-sensitive activity in this region. Furthermore, findings of direct functional parallels between these fMRI and ERP old/new effects give additional credence to the hypothesis that the ERP effect reflects activity in a recollection-sensitive region of the lateral parietal cortex.
Schopenhauer's realist views on mathematics are evident in his criticism of contemporaneous attempts to prove the parallel postulate in Euclidean geometry. Writing shortly before the discovery of hyperbolic geometry demonstrated the logical independence of the axiom—and long before the general theory of relativity revealed that it does not necessarily express a property of physical space—Schopenhauer criticized mathematicians for trying to use indirect concepts to prove what he held was directly evident from intuitive perception. Throughout his writings,"I wanted in this way to stress and demonstrate the great difference, indeed opposition, between knowledge of perception and abstract or reflected knowledge. Hitherto this difference has received too little attention, and its establishment is a fundamental feature of my philosophy ..." – The World as Will and Representation.
Although Chebyshev's paper did not prove the Prime Number Theorem, his estimates for were strong enough for him to prove Bertrand's postulate that there exists a prime number between and for any integer . An important paper concerning the distribution of prime numbers was Riemann's 1859 memoir "On the Number of Primes Less Than a Given Magnitude", the only paper he ever wrote on the subject. Riemann introduced new ideas into the subject, chiefly that the distribution of prime numbers is intimately connected with the zeros of the analytically extended Riemann zeta function of a complex variable. In particular, it is in this paper that the idea to apply methods of complex analysis to the study of the real function originates.
" — Barbara Montero, or that "Every physical effect (that is, caused event) has physical sufficient causes" — Agustin Vincente, (According to Vincente, a number of caveats have to be observed, among which is the postulate that "physical entities" are entities postulated by a true theory of physics, a theory of which we are ignorant today, and that such a true theory "will not include mental (or in general, dubious) concepts" (Note 5, p. 168).) or that "if we trace the causal ancestry of a physical event we need never go outside the physical domain." — Jaegwon Kim. Weaker forms of physical causal closure are synonymous with the causal completeness, the notion that "Every physical effect that has a sufficient cause has a sufficient physical cause.
The property of spin relates to another basic property concerning systems of identical particles: Pauli's exclusion principle, which is a consequence of the following permutation behaviour of an -particle wave function; again in the position representation one must postulate that for the transposition of any two of the particles one always should have i.e., on transposition of the arguments of any two particles the wavefunction should reproduce, apart from a prefactor which is for bosons, but () for fermions. Electrons are fermions with ; quanta of light are bosons with . In nonrelativistic quantum mechanics all particles are either bosons or fermions; in relativistic quantum theories also "supersymmetric" theories exist, where a particle is a linear combination of a bosonic and a fermionic part.
Hume continues his application of epistemology to theology by an extended discussion on heaven and hell. The brunt of this chapter allegedly narrates the opinions, not of Hume, but of one of Hume's anonymous friends, who again presents them in an imagined speech by the philosopher Epicurus. His friend argues that, though it is possible to trace a cause from an effect, it is not possible to infer unseen effects from a cause thus traced. The friend insists, then, that even though we might postulate that there is a first cause behind all things—God—we can't infer anything about the afterlife, because we don't know anything of the afterlife from experience, and we can't infer it from the existence of God.
The central assumption behind his new derivation, presented to the DPG on 14 December 1900, was the supposition, now known as the Planck postulate, that electromagnetic energy could be emitted only in quantized form, in other words, the energy could only be a multiple of an elementary unit: :E = h u where is Planck's constant, also known as Planck's action quantum (introduced already in 1899), and is the frequency of the radiation. Note that the elementary units of energy discussed here are represented by and not simply by . Physicists now call these quanta photons, and a photon of frequency will have its own specific and unique energy. The total energy at that frequency is then equal to multiplied by the number of photons at that frequency.
Henri Poincaré In the second half of the 19th century, there were many attempts to develop a worldwide clock network synchronized by electrical signals. For that endeavor, the finite propagation speed of light had to be considered, because synchronization signals could travel no faster than the speed of light. In his paper The Measure of Time (1898), Henri Poincaré described some important consequences of this process and explained that astronomers, in determining the speed of light, simply assumed that light has a constant speed and that this speed is the same in all directions. Without this postulate, it would be impossible to infer the speed of light from astronomical observations, as Ole Rømer did based on observations of the moons of Jupiter.
Importantly, the control diet sodium reductions from intermediate to low correlated with greater changes in systolic blood pressure than those same changes from high to intermediate (change equal to roughly 40 mmol per day, or 1 gram of sodium). As stated by Sacks, F. et al., reductions in sodium intake by this amount per day correlated with greater decreases in blood pressure when the starting sodium intake level was already at the U.S. recommended dietary allowance, than when the starting level was higher (higher levels are the actual average in the U.S.). These results led researchers to postulate that the adoption of a national lower daily allowance for sodium than the currently held 2,400 mg could be based on the sound scientific results provided by this study.
In 1905, Albert Einstein published his paper on what is now called special relativity.Einstein (1905a) In this paper, by examining the fundamental meanings of the space and time coordinates used in physical theories, Einstein showed that the "effective" coordinates given by the Lorentz transformation were in fact the inertial coordinates of relatively moving frames of reference. From this followed all of the physically observable consequences of LET, along with others, all without the need to postulate an unobservable entity (the aether). Einstein identified two fundamental principles, each founded on experience, from which all of Lorentz's electrodynamics follows: 1\. The laws by which physical processes occur are the same with respect to any system of inertial coordinates (the principle of relativity) 2\.
Phenomenological consequences of asymptotic safety can be expected also for astrophysics and cosmology. Bonanno and Reuter investigated the horizon structure of "renormalization group improved" black holes and computed quantum gravity corrections to the Hawking temperature and the corresponding thermodynamical entropy. By means of an RG improvement of the Einstein–Hilbert action, Reuter and Weyer obtained a modified version of the Einstein equations which in turn results in a modification of the Newtonian limit, providing a possible explanation for the observed flat galaxy rotation curves without having to postulate the presence of dark matter. As for cosmology, Bonanno and Reuter argued that asymptotic safety modifies the very early Universe, possibly leading to a resolution to the horizon and flatness problem of standard cosmology.
Together they developed a theory of "consistent naturalism" in their programmatic text, Art: its Nature and its Laws, wherein they aimed to provide art an exact description and incorporated colloquial elements. They tried, in their description, to eliminate subjectivity from art, to the extent it was scientifically possible, summarized in Holz's formula, ::Art = Nature − x where x is the materials needed to produce art. Ideally, art is to be as close to nature as possible, and it is the artist's responsibility to minimize x in this formula. Holz and Schlaf attempted to apply the theoretical postulate of "consistent naturalism" in their joint works, Papa Hamlet and Die Familie Selicke, plays published under the pseudonym Bjarne P. Holmsen (premiered 1890 in Berlin and Madeburg).
Consider a generic example in which the initial transition state along a concerted pathway is represented by a black dot on a red diagonal (Figure 1). Changing the height of the corners can have two effects on the position of the transition state: it can move along the diagonal, reflecting a change in the Gibbs free energy of the reaction (ΔG°), or perpendicular to it, reflecting a change in the energy of competing pathways. Thus, in accordance with the Hammond postulate, the transition state moves along the diagonal towards the corner that is raised in energy (a Hammond effect) and perpendicular to the diagonal towards the corner that is lowered (an anti-Hammond effect).Thornton, E. R. (1967) J. Am. Chem. Soc.
Hyperreal fields, non- Archimedean ordered fields containing the real numbers as a subfield, may be used to provide a mathematical foundation for nonstandard analysis. Max Dehn used the Dehn field, an example of a non-Archimedean ordered field, to construct non-Euclidean geometries in which the parallel postulate fails to be true but nevertheless triangles have angles summing to .. The field of rational functions over \R can be used to construct an ordered field which is complete (in the sense of convergence of Cauchy sequences) but is not the real numbers.Counterexamples in Analysis by Bernard R. Gelbaum and John M. H. Olmsted, Chapter 1, Example 7, page 17. This completion can be described as the field of formal Laurent series over \R.
Previously, Augustus De Morgan wrote in A Budget of Paradoxes about cranks in multiple subjects, and Dudley wrote a book about angle trisection. However, this is the first book to focus on mathematical crankery as a whole. The book consists of 57 essays, loosely organized by the most common topics in mathematics for cranks to focus their attentions on. The "top ten" of these topics, as listed by reviewer Ian Stewart, are, in order: # squaring the circle, # angle trisection, # Fermat's Last Theorem, # non-Euclidean geometry and the parallel postulate, # the golden ratio, # perfect numbers, # the four color theorem, # advocacy for duodecimal and other non-standard number systems, # Cantor's diagonal argument for the uncountability of the real numbers, and # doubling the cube.
That means that we now have to explain how the first possesses the meaning or representational content by virtue of which it does that, which entails that we have not solved the first problem at all but only added a second one to it. We have “explained” the meaning of one clump of neurons by reference to meaning implicitly present in another clump, and thus merely initiated a vicious explanatory regress. The only way to break the regress would be to postulate some bit of matter that just has its meaning intrinsically, without deriving it from anything else. But there can be no such bit of matter because physics has ruled out the existence of clumps of matter of the required sort.
E. T. Bell wrote about Lobachevsky's influence on the following development of mathematics in his 1937 book Men of Mathematics: > The boldness of his challenge and its successful outcome have inspired > mathematicians and scientists in general to challenge other "axioms" or > accepted "truths", for example the "law" of causality which, for centuries, > have seemed as necessary to straight thinking as Euclid's postulate appeared > until Lobachevsky discarded it.

It is no exaggeration to > call Lobachevsky the Copernicus of Geometry, for geometry is only a part of > the vaster domain which he renovated; it might even be just to designate him > as a Copernicus of all thought.
The importance of the theorem lies in the fact that it has a different proof that does not presuppose the parallel postulate and is therefore valid in non-Euclidean geometry as well. By its help, the mapping that maps every point P of the plane to the midpoint of the segment P´P´´, where P´and P´´ are the images of P under a rotation (in either sense) by a given acute angle about a given center, is seen to be a collineation mapping the whole hyperbolic plane in a 1-1 way onto the inside of a disk, thus providing a good intuitive notion of the linear structure of the hyperbolic plane. In fact, this is called the Hjelmslev transformation.
Subsequent imaging showed there were no objects of 20 Jupiter masses or greater between the disk and the brown dwarf, leading the researchers Neuhäuser and colleagues to postulate that the brown dwarf had an eccentric orbit – if 200 AU were its furthest distance from the primary, then it could come as close as 71 AU with an average distance of 136 AU. Eta Telescopii is in fact a triple star system; further away, separated by 7', is the common proper motion companion HD 181327, a yellow-white main sequence star of spectral type F6V and apparent magnitude 7.0, which has its own debris disk. This disk has a sharply-defined inner edge at 31 AU, indicating a likely planet between 19 and 31 AU from the star.
They'd Rather Be Right somewhat controversially won the Hugo Award for best novel in 1955, the second Hugo ever presented for a novel. In a brief 1982 review of a contemporary reprint of the novel, author David Langford wrote that "though it contains an interesting idea, the book seems an implausible award-winner. It's fine (...) to postulate a machine giving immortality, youth and a perfect complexion to those and only those who can cast aside preconceptions and prejudices (...) The idea, though, is flattened into the ground by the authors' reluctance to do the work which would make it convincing." Langford has also addressed conspiracy theories attributing They'd Rather Be Right's win to Scientology, saying it is more likely that Clifton was popular for his short stories.
Identification with the distant glories of Urartu and its prehistoric forerunners, together with Mount Ararat has come to be a powerful symbol of Armenian ethnicity especially among the diaspora.Anne Elizabeth Redgate, The Armenians, Cambridge University Press, 1995, , p. 276. The idea which claims people living under Urartu were consciously Armenian, essentialist interpretations of Armenian ethnicity over the ages abound in Armenian historiography, and flourished particularly during the Soviet era, with examples such as S. A. Sardarian's Pervobytnoye obshchestvo v Amenii of 1967 which besides "numerous plagiarisms and mistakes" goes as far as to postulate a separate Armenian race native to the Armenian plateau, and attributes the invention of metallurgy to the Armenians (Kohl and Tsetskhladze 1995). Heavily slanted depictions of Urartu are common in this literature.
Ibn al-Haytham was the first mathematician to derive the formula for the sum of the fourth powers, using a method that is readily generalizable for determining the general formula for the sum of any integral powers. He performed an integration in order to find the volume of a paraboloid, and was able to generalize his result for the integrals of polynomials up to the fourth degree. He thus came close to finding a general formula for the integrals of polynomials, but he was not concerned with any polynomials higher than the fourth degree. In the late 11th century, Omar Khayyam wrote Discussions of the Difficulties in Euclid, a book about what he perceived as flaws in Euclid's Elements, especially the parallel postulate.
For Newton, it was not precisely the centre of the Sun or any other body that could be considered at rest, but rather "the common centre of gravity of the Earth, the Sun and all the Planets is to be esteem'd the Centre of the World", and this centre of gravity "either is at rest or moves uniformly forward in a right line" (Newton adopted the "at rest" alternative in view of common consent that the centre, wherever it was, was at rest).Text quotations are from 1729 translation of Newton's Principia, Book 3 (1729 vol.2) at pp. 232–233. Newton's postulate of an invisible force able to act over vast distances led to him being criticised for introducing "occult agencies" into science.
The physicist Robert L. Forward has argued that an interstellar mission that cannot be completed within 50 years should not be started at all. Instead, assuming that a civilization is still on an increasing curve of propulsion system velocity and not yet having reached the limit, the resources should be invested in designing a better propulsion system. This is because a slow spacecraft would probably be passed by another mission sent later with more advanced propulsion (the incessant obsolescence postulate). On the other hand, Andrew Kennedy has shown that if one calculates the journey time to a given destination as the rate of travel speed derived from growth (even exponential growth) increases, there is a clear minimum in the total time to that destination from now.
The third chapter discusses the confluence of Arabic and European mathematics, into the 18th century, with topics including the symmetries of folded objects and the attempted use of folding to prove the parallel postulate. Although Eugenio Beltrami continued to use folded models to investigate non-Euclidean geometry into the 19th century, the fourth chapter of the book argues that other 19th-century uses of folding were more pedagogical, including the use of folded models to demonstrate mathematical concepts, their applications in chemistry, and the introduction of folding into kindergarten programs by Friedrich Fröbel. The late 19th century also saw the publication in India and then the west of the book Geometric Exercises in Paper Folding, by T. Sundara Row. The final two chapters concern the 20th century and current topics of research in this area.
Aquinas saw that in any subsisting extramental (existing outside the mind) thing, one finds a couplet of metaphysical principles: one is the "essence" which makes the thing to be what it is, the other is the which gives the thing and its "essence" actual existence. The observation that individual things display instantiations of a particular "essence" led Aquinas to postulate that what gives actual existence to a thing and to its "essence" – the – is unique, in the sense that the perfection of cannot be said to be common in the way an "essence" is said to be common. Things instantiating the essence of (being like a horse), for example, are said to be similar because of their . The essence of is what makes horses the same under a common category.
The Raskol movement gained in strength after the church sobor in 1666–67, which had anathemized the defenders of the old faith as heretics and made decisions with regards to their punishment. Especially members of the low-ranking clergy, who had severed their relations with the church, became the leaders of the opposition. Propagation of the split with the church in the name of preservation of the Orthodox faith as it had existed until the reforms was the main postulate of their ideology. The most dramatic manifestations of the Raskol included the practice of the so-called ognenniye kreshcheniya (огненные крещения, or baptism by fire), or self-immolation, practiced by the most radical elements in the Old Believers' movement, who thought that the end of the world was near.
Jonassohn and Björnson go on to say that none of these alternative definitions have gained widespread support for various reasons.Kurt Jonassohn & Karin Solveig Björnson, Genocide and Gross Human Rights Violations in Comparative Perspective: In Comparative Perspective, Transaction Publishers, 1998, . pp. 133–135 Jonassohn and Björnson postulate that the major reason why no single generally accepted genocide definition has emerged is because academics have adjusted their focus to emphasise different periods and have found it expedient to use slightly different definitions to help them interpret events. For example, Frank Chalk and Kurt Jonassohn studied the whole of human history, while Leo Kuper and R. J. Rummel in their more recent works concentrated on the 20th century, and Helen Fein, Barbara Harff and Ted Gurr have looked at post World War II events.
In 1952, Wardrop stated two principles that formalize different notions of equilibrium, and introduced the alternative behavior postulate of the minimization of the total travel costs: User equilibrium. Wardrop's first principle of route choice, now known as "user equilibrium", "selfish Wardrop equilibrium" or just "Wardrop equilibrium", and is identical to the notion postulated by Knight, became accepted as a sound and simple behavioral principle to describe the spreading of trips over alternate routes because of congested conditions. It states that the journey times in all routes actually used are equal and less than those that would be experienced by a single vehicle on any unused route. The traffic flows that satisfy this principle are usually referred to as "user equilibrium" (UE) flows, since each user chooses the route that is the best.
5, 190 (2010)R.A. Zubarev, Role of stable isotopes in life – Testing isotopic resonance hypothesis, Genomics Proteomics Bioinformatics 9, 15 (2011) postulates that certain isotopic compositions of chemical elements affect kinetics of chemical reactions involving molecules built of these elements. The isotopic compositions for which this effect is predicted are called resonance isotopic compositions. Fundamentally, the IsoRes hypothesis relies on a postulate that less complex systems exhibit faster kinetics than equivalent but more complex systems. Furthermore, system’s complexity is affected by its symmetry (more symmetric systems are simpler), and symmetry (in general meaning) of reactants may be affected by their isotopic composition. The term “resonance” relates to the use of this term in nuclear physics, where peaks in the dependence of a reaction cross section upon energy are called “resonances”.
Tyson examines the basic structure of atoms, their protons, neutrons, and electrons, and the nature of nuclear fusion, a process found to occur within most stars. He then discusses the existence of neutrinos created by these nuclear processes, and the attempts to detect such subatomic particles which normally pass through matter, requiring subterranean facilities like the Super- Kamiokande which were used to detect neutrinos from the supernova SN 1987A in the Large Magellanic Cloud. These neutrinos were detected before any light from the explosion reached us; this was due to their ability to pass through the matter of the dying star itself. Tyson compares how neutrinos were postulated by Wolfgang Pauli to account for the conservation of energy from nuclear reactions in the same manner as Darwin's postulate on the long-tongued moth.
The basis for Schrödinger's equation, on the other hand, is the energy of the system and a separate postulate of quantum mechanics: the wave function is a description of the system.Molecular Quantum Mechanics Parts I and II: An Introduction to Quantum Chemistry (Volume 1), P. W. Atkins, Oxford University Press, 1977, The Schrödinger equation is therefore a new concept in itself; as Feynman put it: The foundation of the equation is structured to be a linear differential equation based on classical energy conservation, and consistent with the De Broglie relations. The solution is the wave function , which contains all the information that can be known about the system. In the Copenhagen interpretation, the modulus of is related to the probability the particles are in some spatial configuration at some instant of time.
The first, of which has been attributed to Ding, assumes for the DIT that the DC component, U depends on not only the mid-level of the AC voltages, V1and V2, but also the duty cycle, d of the waveform: : U = dV_1 + (1-d) V_2 Whereas, the second but more general postulate assumes that there is no DC component unless there is an explicit DC voltage offset added to the waveforms. The latter interpretation is explained by the change to the stability diagram that results when the duty cycle moves away from d = 0.5. When this happens the range of stable q and a values for both quadrupole axes change. These changes cause the motion of ions to be more displaced along one axis compared to the other.
Proponents of Two House theology espouse their belief that the phrase "House of Judah" in scripture refers to Jews, while "the House of Israel" refers to the Ten Lost Tribes of Israel, or Ephraim. Where scripture states the House of Israel and Judah will again be "one stick" (), it is believed to be referring to the End Times, immediately prior to the Second Coming, when many of those descended from Israel will come back to Israel. Advocates of this theology postulate that the reason so many "gentiles" are converting to Messianic Judaism is that the vast majority of them are truly Israelites. Like One Law groups, the Two House movement has many superficial similarities to Messianic Judaism, such as their belief in the ongoing validity of the Mosaic Covenant.
In physics, horror vacui, or plenism (), commonly stated as "nature abhors a vacuum", is a postulate attributed to Aristotle, who articulated a belief, later criticized by the atomism of Epicurus and Lucretius, that nature contains no vacuums because the denser surrounding material continuum would immediately fill the rarity of an incipient void. He also argued against the void in a more abstract sense (as "separable"), for example, that by definition a void, itself, is nothing, and following Plato, nothing cannot rightly be said to exist. Furthermore, insofar as it would be featureless, it could neither be encountered by the senses, nor could its supposition lend additional explanatory power. Hero of Alexandria challenged the theory in the first century CE, but his attempts to create an artificial vacuum failed.
Historians of the nineteenth and early twentieth centuries theorized that the terem was adopted from misogynistic practices of the Mongol Empire during the occupation of the Golden Horde, in the thirteenth century. The earliest source which references the terem does not appear until the sixteenth century, but it is uncertain how long it had been in practice prior to the writing of Sigismund von Herberstein’s 1557 account of Russia (see above, Practice). With Herberstein’s account, historians “postulate a radical change in women’s status during the time of Ivan III,” though it is unlikely that such a dramatic social change was undertaken so suddenly. This evidence has led several modern historians, including Nancy S. Kollman, to point to the end of the fifteenth century for the origins of female seclusion in Muscovy.
The formation and alignment of hastati Hastati appear to have been remnants of the old third class of the army under the Etruscan kings when it was reformed by Marcus Furius Camillus. The third class stood in the last few ranks of a very large phalanx and were equipped in a similar manner to hastati, although they were more often than not relegated to providing missile support to the higher classes rather than fighting themselves. Penrose and Southern postulate that it is probable that engagements with the Samnites and a crushing defeat at the hands of the Gallic warlord Brennus, who both used many smaller military units rather than a few larger ones, taught the Romans the importance of flexibility and the inadequacy of the phalanx on the rough, hilly ground of central Italy.
He began by postulating -- "The principle of non-derogation is however based upon the presumed intention of the parties. The rights derived from the principle must have a consensual origin."Lord Hoffman's postulate, however, simply refuses to accept Lord Templeman's clearly expressed concept that any intention not to derogate from a grant is constructive, that is to say that it is implied by law irrespective of the actual wishes of the grantor, because perceived considerations of public policy require that certain consequences shall follow from certain transactions in order that society shall operate in accordance with what Lord Templeman considered necessary to the operation of a well-ordered State. In short, Lord Hoffman did not agree with Lord Templeman's unarticulated hierarchy of values, nor did he articulate his own.
The span of the largest vault was eighteen paces, its width eight. Small arched chambers immediately under the pavement reduced the load of the bridge; similar relieving chambers also appear in neighbouring ancient bridges such as the Makestos Bridge and the Aesepus Bridge, leading Frederick William Hasluck to postulate a common origin under the reign of emperor Constantine († 337 AD). Eighty years later, Janke could still identify several semi-circular arches at the left bank, along with piers featuring polished ashlar of 100 × 50 cm, as characteristically for Roman bridge building. Hardly a decade later, however, Hasluck essentially only found a tile-vaulted arch of the western abutment and an adjoining pier, the bridge having been plundered in the meantime for building material for the Karabogha–Boghashehr () road.
He became the Walker professor in 1970, and retired to become an emeritus professor in 1973. The Robert H. Breusch Prize in Mathematics, for the best senior thesis from an Amherst student, was endowed in his memory. As a mathematician, Breusch was known for his new proof of the prime number theorem. and for the many solutions he provided to problems posed in the American Mathematical Monthly. His thesis work combined Bertrand's postulate with Dirichlet's theorem on arithmetic progressions by showing that each of the progressions 3i + 1, 3i + 2, 4i + 1, and 4i + 3 (for i = 0, 1, 2, ...) contains a prime number between x and 2x for every x ≥ 7... For instance, he proved that for n > 47 there is at least one prime between n and (9/8)n.
There are still ongoing discussions about the correct form of equations for the Thomas rotation in different reference systems with contradicting results. Goldstein: :The spatial rotation resulting from the successive application of two non-collinear Lorentz transformations have been declared every bit as paradoxical as the more frequently discussed apparent violations of common sense, such as the twin paradox. Einstein's principle of velocity reciprocity (EPVR) reads :We postulate that the relation between the coordinates of the two systems is linear. Then the inverse transformation is also linear and the complete non- preference of the one or the other system demands that the transformation shall be identical with the original one, except for a change of to With less careful interpretation, the EPVR is seemingly violated in some models.
Here, the word "Greenhouse" refers to Linda Greenhouse, a Pulitzer Prize winning reporter who covered the Supreme Court for the New York Times for 40 years. Silberman used the term to postulate a tendency of conservative Supreme Court Justices to vote with the liberals more often as their careers progress due to a desire for favorable press coverage. He said "It seems that the primary objective of The Times's legal reporters is to put activist heat on recently appointed Supreme Court justices." The existence of the Greenhouse Effect has been challenged by some commentators, who note it presumes a "vast, hegemonic liberal control over the media and academia" and question whether professional decision makers who have "come to their views despite years of elite education and exposure to elite opinion" are really so malleable.
Some fans have speculated that in Superman/Batman # 80 (March 2011), Laurel is revealed to be a member of the Superman Dynasty in the 31st century, where she operates as Superwoman, with associates including Brane Taylor and Kent Shakespeare – the Batman and Superman of that era – and Tom Wayne, the Robin from the Robin 3000 series. This speculation also assumes that she is once again going by the name "Elna", which they postulate it could be to distance herself from the Manhunter who (according to this fan theory) impersonated her. However, there is no published evidence to suggest that the two characters (Laurel and Elna Kent) are the same, nor is there any evidence to support the idea that there is or was, a 'real' Laurel who was impersonated by a Manhunter android.
For example, the first and fourth of Euclid's postulates, that there is a unique line between any two points and that all right angles are equal, hold in elliptic geometry. Postulate 3, that one can construct a circle with any given center and radius, fails if "any radius" is taken to mean "any real number", but holds if it is taken to mean "the length of any given line segment". Therefore any result in Euclidean geometry that follows from these three postulates will hold in elliptic geometry, such as proposition 1 from book I of the Elements, which states that given any line segment, an equilateral triangle can be constructed with the segment as its base. Elliptic geometry is also like Euclidean geometry in that space is continuous, homogeneous, isotropic, and without boundaries.
Many alternative axioms can be formulated which are logically equivalent to the parallel postulate (in the context of the other axioms). For example, Playfair's axiom states: :In a plane, through a point not on a given straight line, at most one line can be drawn that never meets the given line. The "at most" clause is all that is needed since it can be proved from the remaining axioms that at least one parallel line exists. A proof from Euclid's Elements that, given a line segment, one may construct an equilateral triangle that includes the segment as one of its sides: an equilateral triangle ΑΒΓ is made by drawing circles Δ and Ε centered on the points Α and Β, and taking one intersection of the circles as the third vertex of the triangle.
In the case of doubling the cube, the impossibility of the construction originates from the fact that the compass and straightedge method involve equations whose order is an integral power of two,Theorem 120, Elements of Abstract Algebra, Allan Clark, Dover, while doubling a cube requires the solution of a third-order equation. Euler discussed a generalization of Euclidean geometry called affine geometry, which retains the fifth postulate unmodified while weakening postulates three and four in a way that eliminates the notions of angle (whence right triangles become meaningless) and of equality of length of line segments in general (whence circles become meaningless) while retaining the notions of parallelism as an equivalence relation between lines, and equality of length of parallel line segments (so line segments continue to have a midpoint).
Anyone who dared such a meaning in those times would not be alive for much longer; men were burned for less. Only modern pagan writers far from the fires of Inquisition might suggest that under the very noses of the authors of the Inquisition, the Don and Dona of Spain, and the staunchest advocates of Catholicism, Columbus, Juan de la Cosa and all his Basque countrymen, who were indispensable to the expedition, the patron saint of the expedition and the entire new Spanish Empire could be so insulted by a salacious ship name, and the same can be said of those who postulate salacious overtones for the Nina and Pinta. The 1571 Italian text of the Biography is: > ... traversarano ad un'altra isola, a cui l'Ammiraglio pose nome > Marigalante, per hauer la nave Capitana tal nome ...
Parnia and others have suggested that a mind that is mediated by, but not produced by, the brain, is a possible way to explain NDE. Science writer Mike McRae has noted "While Parnia's work contributes valuable data to understanding NDE as a cultural phenomenon, his speculations do indeed sit on the brink of pseudoscience." Neurologist Michael O'Brien has written that "most people would not find it necessary to postulate such a separation between mind and brain to explain the events," and suggested that further research is likely to provide a physical explanation for near-death experiences. Psychologist and lecturer Susan Blackmore appeared with Parnia and Peter Fenwick on a BBC documentary called "The Day I Died" and disagreed with their interpretations of NDEs, finding purely physical explanations to be more plausible.
They pointed out that some of the keywords used were 'core asset', 'core product', 'product quality' and 'preserve'. They argued that the treatment of the environment as a marketable product was clear and that such documents provide a good list of advice for Third World governments regarding sustainable tourism but do not actually provide the resources to incorporate them into the development of their tourism industries. It is arguments such as these that postulate that there is a gap between the advice given by non-governmental or inter-governmental organizations to Third World governments and what can actually be brought to realization. These arguments try and persuade readers that documents like the one released by the WTTC that the development of sustainable tourism actually 'bypasses the interests of local people'.
Giovanni Gentile's actual idealism, sometimes called "philosophy of immanence" and the metaphysics of the "I", "affirms the organic synthesis of dialectical opposites that are immanent within actual or present awareness".M. E. Moss, Mussolini's Fascist Philosopher: Giovanni Gentile Reconsidered, Peter Lang, p. 7. His so-called method of immanence "attempted to avoid: (1) the postulate of an independently existing world or a Kantian Ding-an-sich (thing-in-itself), and (2) the tendency of neo-Hegelian philosophy to lose the particular self in an Absolute that amounts to a kind of mystical reality without distinctions." Political theorist Carl Schmitt used the term in his book Politische Theologie (1922), meaning a power within some thought, which makes it obvious for the people to accept it, without needing to claim being justified.
But Hahn and Meitner had a sample from which they had regularly removed its mother isotope, mesothorium (), over a period of several years, allowing the radiothorium to decay away. Even then, it was still more difficult to work with because its induced decay products from neutron irradiation were isotopes of the same elements produced by thorium's own radioactive decay. What they found was three different decay series, all alpha emitters—a form of decay not found in any other heavy element, and for which Meitner once again had to postulate multiple isomers. They did find an interesting result: these (n, α) decay series occurred simultaneously when the energy of the incident neutrons was less than 2.5 MeV; when they had more, an (n, γ) reaction that formed was favoured.
Viewed as a theory of elementary particles, Lorentz's electron/ether theory was superseded during the first few decades of the 20th century, first by quantum mechanics and then by quantum field theory. As a general theory of dynamics, Lorentz and Poincare had already (by about 1905) found it necessary to invoke the principle of relativity itself in order to make the theory match all the available empirical data. By this point, most vestiges of a substantial aether had been eliminated from Lorentz's "aether" theory, and it became both empirically and deductively equivalent to special relativity. The main difference was the metaphysical postulate of a unique absolute rest frame, which was empirically undetectable and played no role in the physical predictions of the theory, as Lorentz wrote in 1909,Lorentz 1909, p.
Tyson then describes the nature of black holes, their enormous gravitational forces that can even capture light, and their discovery via X-ray sources such as Cygnus X-1. Tyson uses the Ship of Imagination to provide a postulate of the warping of spacetime and time dilation as one enters the event horizon of the black hole, and the possibility that these may lead to other points within our universe or others, or even time travel. Tyson ends on noting that Herschel's son, John would be inspired by his father to continue to document the known stars as well as contributions towards photography that play on the same nature of deep time used by astronomers. Animated sequences in this episode feature William and John Herschel; Patrick Stewart provided the voice for William in these segments.
Modern substance theory differs. For example Kant's "Ding an sich", or "thing in itself", is generally described as whatever is its own cause, or alternatively as a thing whose only property is that it is that thing (or, in other words, that it has only that property). However, this notion is subject to the criticism, as by Nietzsche, that there is no way to directly prove the existence of any thing which has no properties, since such a thing could not possibly interact with other things and thus would be unobservable and indeterminate. On the other hand, we may need to postulate a substance that endures through change in order to explain the nature of change—without an enduring factor that persists through change, there is no change but only a succession of unrelated events.
There is not much evidence of Thucydides's influence in Niccolò Machiavelli's The Prince (1513), which held that the chief aim of a new prince must be to "maintain his state" [i.e., his power] and that in so doing he is often compelled to act against faith, humanity, and religion. Later historians, such as J. B. Bury, however, have noted parallels between them: > If, instead of a history, Thucydides had written an analytical treatise on > politics, with particular reference to the Athenian empire, it is probable > that ... he could have forestalled Machiavelli ... [since] the whole > innuendo of the Thucydidean treatment of history agrees with the fundamental > postulate of Machiavelli, the supremacy of reason of state. To maintain a > state, said the Florentine thinker, "a statesman is often compelled to act > against faith, humanity and religion".
Girolamo Saccheri (1667-1733) pursued the same line of reasoning more thoroughly, correctly obtaining absurdity from the obtuse case (proceeding, like Euclid, from the implicit assumption that lines can be extended indefinitely and have infinite length), but failing to refute the acute case (although he managed to wrongly persuade himself that he had). In 1766 Johann Lambert wrote, but did not publish, Theorie der Parallellinien in which he attempted, as Saccheri did, to prove the fifth postulate. He worked with a figure that today we call a Lambert quadrilateral, a quadrilateral with three right angles (can be considered half of a Saccheri quadrilateral). He quickly eliminated the possibility that the fourth angle is obtuse, as had Saccheri and Khayyám, and then proceeded to prove many theorems under the assumption of an acute angle.
In the 1980s, economists Daniel Khazzoom and Leonard Brookes revisited the Jevons paradox for the case of society's energy use. Brookes, then chief economist at the UK Atomic Energy Authority, argued that attempts to reduce energy consumption by increasing energy efficiency would simply raise demand for energy in the economy as a whole. Khazzoom focused on the narrower point that the potential for rebound was ignored in mandatory performance standards for domestic appliances being set by the California Energy Commission. In 1992, the economist Harry Saunders dubbed the hypothesis that improvements in energy efficiency work to increase (rather than decrease) energy consumption the Khazzoom–Brookes postulate, and argued that the hypothesis is broadly supported by neoclassical growth theory (the mainstream economic theory of capital accumulation, technological progress and long-run economic growth).
P. 52–63 - online version at The vision is similar to the second vision recounted by Smith's father Joseph Smith Sr. prior to publication of the Book of Mormon. The vision of Smith Sr. contained a tree with delicious fruit, a path, and a large building where the wicked looked down in scorn of the righteous; however, the vision of Smith Sr. contained a rope rather than an iron rod, and there were other minor differences.. Because of the similarity, secular church scholars postulate that Smith Sr.'s dream is the source for the tree of life vision.Fawn M. Brodie, No Man Knows My History: The Life of Joseph Smith (New York: Alfred A. Knopf, 1945), 58. Grant H. Palmer, An Insider's View of Mormon Origins (Salt Lake City: Signature Books, 2002) 70-71.
In 2016 -2017 he formulated the so-called "Gafurov postulate" of political science on Russian TV. According to this hypothesis, in any election "from the United States to the DPRK, from India to Russia, from Switzerland to the People's China, from Germany to Syria," the number of illegal, "thrown in" votes is approximately the same, in cases of one or two candidates ranging from 5% to 10% of votes. Gafurov assumes the existence of a stable mathematical expectation of this figure in the presence of a sufficiently large number of polling stations and a large number of elections. "Gafurov's Political Science Hypothesis" is used to calculate the budgets of election campaigns in Russia. Gafurov had struggled to support the Syrian government, but after direct involvement of Russian forces in the Syrian conflict, he started to speak against the main line of Russian propaganda.

Broad Center for Biological Sciences Richard Feynman was among the most well-known physicists associated with Caltech, having published the Feynman Lectures on Physics, an undergraduate physics text, and popular science texts such as Six Easy Pieces for the general audience. The promotion of physics made him a public figure of science, although his Nobel-winning work in quantum electrodynamics was already very established in the scientific community. Murray Gell-Mann, a Nobel-winning physicist, introduced a classification of hadrons and went on to postulate the existence of quarks, which is currently accepted as part of the Standard Model. Long-time Caltech President Robert Andrews Millikan was the first to calculate the charge of the electron with his well-known oil-drop experiment, while Richard Chace Tolman is remembered for his contributions to cosmology and statistical mechanics.
Previous versions of iOS stored similar information in a file called "h-cells.plist". F-Secure discovered that the data is transmitted to Apple twice a day and postulate that Apple is using the information to construct their global location database similar to the ones constructed by Google and Skyhook through wardriving. Nevertheless, unlike the Google "Latitude" application, which performs a similar task on Android phones, the file is not dependent upon signing a specific EULA or even the user's knowledge, but it is stated in the 15,200 word-long terms and conditions of the iPhone that "Apple and [their] partners and licensees may collect, use, and share precise location data, including the real-time geographic location of [the user's] Apple computer or device". The file is also automatically copied onto the user's computer once synchronized with the iPhone.
Libertarian scenarios postulate that intelligent machines, uploaded humans, cyborgs, and unenhanced humans will coexist peacefully in a framework focused on respecting property rights. Because industrial productivity is no longer gated by scarce human labor, the value of land skyrockets compared to the price of goods; even remaining "Luddite" humans who owned or inherited land should be able to sell or lease a small piece of it to the more-productive robots in exchange for a perpetual annuity sufficient to easily indefinitely meet all of their basic financial needs. Such people can live as long as they choose to, and are free to engage in almost any activity they can conceive of, for pleasure or for self- actualization, without financial concern. Advanced technologies enable entirely new modes of thought and experience, thus adding to the palette of possible feelings.
