This can be regarded as a part of geometric topology. It may also be used to refer to the study of topological spaces of dimension 1, though this is more typically considered part of continuum theory.

In the mathematical field of point-set topology, a continuum (plural: "continua") is a nonempty compact connected metric space, or, less frequently, a compact connected Hausdorff space. Continuum theory is the branch of topology devoted to the study of continua.

Upward places the RCM within a post-custodial, postmodern and structuration conceptual framework. Australian academics and practitioners continue to explore, develop and extend the RCM and records continuum theory, along with international collaborators, via the Records Continuum Research Group (RCRG) at Monash University.

William Fuller Brown Jr. (21 October 1904 – 1983) was an American physicist who developed the theory of micromagnetics, a continuum theory of ferromagnetism that has had numerous applications in physics and engineering. He published three books: Magnetostatic Principles in Ferromagnetism, Micromagnetics, and Magnetoelastic Interactions.

Typical behaviors observed in rocks include strain softening, perfect plasticity, and work hardening. Application of continuum theory is possible in jointed rocks because of the continuity of tractions across joints even through displacements may be discontinuous. The difference between an aggregate with joints and a continuous solid is in the type of constitutive law and the values of constitutive parameters.

During his career, he published more than 150 papers in Italian and international journals. The beginning of his scientific production was under Grioli’s scientific influence: Galletto worked on the topic of his laurea thesis, i.e. on the theory of continua having asymmetric stress characteristics. However, soon he followed his independent research path, with pioneering works that forerun the so called generalised continuum theory.

All three of these types of distortions incur an energy penalty. They are distortions that are induced by the boundary conditions at domain walls or the enclosing container. The response of the material can then be decomposed into terms based on the elastic constants corresponding to the three types of distortions. Elastic continuum theory is a particularly powerful tool for modeling liquid crystal devices and lipid bilayers.

R. H. Bing (October 20, 1914 in Oakwood, Texas – April 28, 1986 in Austin, Texas) was an American mathematician who worked mainly in the areas of geometric topology and continuum theory. His father was named Rupert Henry, but Bing's mother thought that "Rupert Henry" was too British for Texas. She compromised by abbreviating it to R. H. Consequently, R. H. does not stand for a first or middle name.

He started his university studies in Rome as a student of Severi: however his studies were interrupted due to the military service, which led him to Padua.According to the obituary . There he graduated with honours in 1960 under Giuseppe Grioli’s guidance, with a thesis on the continuum theory with asymmetric stress: from 1961 to 1968 he worked in Padua as an associate professor,See also . holding also courses on differential geometry as a lecturer.

In psychological studies, the term is often used to describe degree of (general) sexual aversion versus (general) interest in sex. In this sense erotophobia is descriptive of one's place in a range on a continuum (theory) of sexual feeling or aversion to feeling. Erotophobes score high on one end of the scale that is characterized by expressions of guilt and fear about sex. Psychologists sometimes attempt to describe sexuality on a personality scale.

Huang has been working on mechanics of materials and structures across multiple scales, such as the mechanism-based strain gradient plasticity theory, and atomistic-based continuum theory for carbon nanotubes. In recent years he has focused on mechanics and thermal analysis of stretchable and dissolvable electronics with applications to energy harvesting and medicine, and mechanically guided, deterministic 3D assembly. His work on the electronic tattoos has been reported by NBC Learn (the education arm of NBC).

Peter Scott, a contemporary at the Commonwealth Archives Office, is also recognized as a core influence on Australian records continuum theory with his development of the Australian Series System, a registry system that helped identify and document the complex and multiple "social, functional, provenancial, and documentary relationships" involved in managing records and recordkeeping processes over spacetime. Further influences on the RCRG group include archival professionals and researchers like David Bearman and his work on transactionality and systems thinking, and Terry Cook's ideas about postcustodialism and macroappraisal. Broader influences to the continuum theory come from philosophers and social theorists Jacques Lacan, Michel Foucault, Jacques Derrida, and Jean-François Lyotard, as well as sociologist Anthony Giddens, with structuration theory being a core component of understanding social interaction over spacetime. Canadian archivist Jay Atherton's critique of the division between records managers and archivists in the 1980s and use of the term "records continuum" re-commenced the conversation MacLean began during his career and helped to bring his ideas and this term to Australian records continuum thinking.

Edwin E. Moise was born December 22, 1918 in New Orleans, Louisiana. He graduated from Tulane University in 1940. He worked as a cryptanalyst and Japanese translator for the Office of the Chief of Naval Operations during World War II. He received his Ph.D. degree in mathematics from the University of Texas in 1947. His dissertation was titled "An indecomposable continuum which is homeomorphic to each of its nondegenerate subcontinua," a topic in continuum theory, and was written under the direction of Robert Lee Moore.

Scientists in the UK have formulated a mathematical model that predicts the shape of a ponytail given the length and random curvature (or curliness) of a sample of individual hairs. The Ponytail Shape Equation provides an understanding of how a ponytail is swelled by the outward pressure which arises from interactions between the component hairs."Science behind ponytail revealed."(2012, February 13) The researchers developed a general continuum theory for a bundle of hairs, treating each hair as an elastic filament with random intrinsic curvature.

Although most lattice field theories are not exactly solvable, they are of tremendous appeal because they can be studied by simulation on a computer. One hopes that, by performing simulations on larger and larger lattices, while making the lattice spacing smaller and smaller, one will be able to recover the behaviour of the continuum theory. Just as in all lattice models, numerical simulation gives access to field configurations that are not accessible to perturbation theory, such as solitons. Likewise, non-trivial vacuum states can be discovered and probed.

Between 1870 and 1890 the vortex atom theory, which purported that an atom was a vortex in the aether, was popular among British physicists and mathematicians. Thomson pioneered the theory, which was distinct from the seventeenth century vortex theory of Descartes in that Thomson was thinking in terms of a unitary continuum theory, whereas Descartes was thinking in terms of three different types of matter, each relating respectively to emission, transmission, and reflection of light. About 60 scientific papers were written by approximately 25 scientists. Following the lead of Thomson and Tait, the branch of topology called knot theory was developed.

The RCM is a representation of what is commonly referred to as records continuum theory, as well as Australian continuum thinking and/or approaches. These ideas were evolved as part of an Australian approach to archival management espoused by Ian Maclean, Chief Archivist of the Commonwealth Archives Office in Australia in the 1950s and 1960s. Maclean, whose ideas and practices were the subject of the first RCRG publication in 1994, referred in a 1959 American Archivist article to a "continuum of (public) records administration" from administrative efficiency through recordkeeping to the safe keeping of a "cultural end-product". Maclean's vision challenged the divide between current recordkeeping and archival practice.

From the equation above, it follows that fluid flow in nanocapillaries is governed by the κa product, that is, the relative sizes of the Debye length and the pore radius. By adjusting these two parameters and the surface charge density of the nanopores, fluid flow can be manipulated as desired. Despite the fact that nanofluidics gives rise to entirely new phenomena in comparison to ordinary large-scale fluid mechanics, it is possible to develop a fundamental continuum theory governing momentum transport in isotropic nanofluidic systems. This theory, which extends the classical Navier−Stokes equation, shows excellent agreement with computer simulations of systems on the nanometer length.

The book Histories of performance documentation (ed. by Gabriella Giannachi and Jonah Westerman), explores the relationship between performance art and the institution. Contributions from Laurenson (Tate) and Gabriella Giannachi (University of Exeter) are particularly relevant. While Laurenson stresses the idea of an artwork's socialization and its being interwoven with an artwork's trajectory (which she connects with “continuum theory”), Giannachi provides new frameworks for understanding the conservation of performance art: first by acknowledging re- enactment as a practice of preservation, then by recognizing the increasing importance of audience members as content co-producers, and finally by understanding the artwork as “a social network of activities”.

Williams’ early research was in elementary particle physics, then during her second postdoctoral position she started working in classical general relativity. Eventually she combined these two interests by working in quantum gravity in an attempt to find a unified theory of quantum mechanics and general relativity. Her particular approach, called Regge calculus, is a version of discrete gravity where curved space-times are approximated by collections of flat simplices. This may be thought of as a generalisation of geodesic domes to higher dimensions. Williams’ work on Regge calculus includes the classical evolution of model universes, and numerical simulations of discrete quantum gravity, together with investigations of the relationship between Regge calculus and the continuum theory.

A quark and an antiquark (red color) are glued together (green color) to form a meson (result of a lattice QCD simulation by M. Cardoso et al.) Among non-perturbative approaches to QCD, the most well established one is lattice QCD. This approach uses a discrete set of spacetime points (called the lattice) to reduce the analytically intractable path integrals of the continuum theory to a very difficult numerical computation which is then carried out on supercomputers like the QCDOC which was constructed for precisely this purpose. While it is a slow and resource- intensive approach, it has wide applicability, giving insight into parts of the theory inaccessible by other means, in particular into the explicit forces acting between quarks and antiquarks in a meson. However, the numerical sign problem makes it difficult to use lattice methods to study QCD at high density and low temperature (e.g.
