When influential people speak, conversations spread like ripples in a pond.

These waves are often likened to ripples in a pond, except they travel vertically rather than horizontally.
|
|
And when they move, they create waves in this space-time, a bit like a boat leaving ripples in a pond.
|
|
And when these objects move, they create ripples in space-time, just like how a moving boat creates ripples in a pond.

But one of the theory's predictions was that certain gravitational events could send light-speed waves through space, like ripples in a pond.
|
|
And when these massive objects move, they create undulating space-time ripples, or gravitational waves, kind of like creating ripples in a pond.
|
|
The waves travel outward on the ocean's surface, like ripples in a pond, and can slow down but grow in size as they come ashore.

Einstein theorized that objects actually leave imprints on the space-time around them — and when objects move, they create ripples in space-time, similar to how a moving object creates ripples in a pond.
|
|
He argued that every object in the Universe warps the space and time around it, and when an object moves, it creates ripples in this space-time — gravitational waves — a bit like ripples in a pond.

Algorithms made judgements on who to pay attention to (ranking people who hung around longer higher than those who just arrived, for example), while the robots' motions flowed from one arm to the next like ripples in a pond.

These waves, known to meteorologists as ridges and troughs, get carried downstream like ripples in a pond, affecting weather in Alaska and the continental U.S. Regardless of its path, it's clear that the storm will be intense, potentially peaking as a Category 4 or 5.

These waves, known to meteorologists as ridges and troughs, get carried downstream like ripples in a pond, affecting weather in Alaska and the continental U.S. What this means is that the weather pattern across the U.S. next week will probably feature a wavy jet stream.

"This work shows that the stellar disk of the Milky Way is a dynamically active place, where spiral arms and the Galactic bar leave their marks on the orbits of stars like ripples in a pond—a pond that has perhaps recently felt the splash of a small stone in the form of a merging dwarf galaxy," astronomer Stacy McGaugh from Case Western Reserve University told Gizmodo.

In a homogeneous elastic medium, complex oscillations (vibrations in a material or light flows) can be described as the superposition of many simple sinusoidal waves, either transverse (linearly polarized) or longitudinal. The vibrations of a violin string, for example, can be analyzed as the sum of many transverse waves of different frequencies, that displace the string either up or down or left to right. The ripples in a pond can be analyzed as a combination of transverse and longitudinal waves (gravity waves) that propagate together.

Physics of the Impossible: A Scientific Exploration Into the World of Phasers, Force Fields, Teleportation, and Time Travel is a book by theoretical physicist Michio Kaku. Kaku uses discussion of speculative technologies to introduce topics of fundamental physics to the reader. The topic of invisibility becomes a discussion on why the speed of light is slower in water than in vacuum, that electromagnetism is similar to ripples in a pond, and Kaku discusses newly developed composite materials. The topic of Star Trek "phasers" becomes a lesson on how lasers work and how laser-based research is conducted.

The SDSS-III's Baryon Oscillation Spectroscopic Survey (BOSS) was designed to measure the expansion rate of the Universe. It mapped the spatial distribution of luminous red galaxies (LRGs) and quasars to determine their spatial distribution and detect the characteristic scale imprinted by baryon acoustic oscillations in the early universe. Sound waves that propagate in the early universe, like spreading ripples in a pond, imprint a characteristic scale on the positions of galaxies relative to each other. It was announced that BOSS had measured the scale of the universe to an accuracy of one percent, and was completed in Spring 2014.

Direct observation of phonon-polariton propagation was made possible by real-space imaging, in which the spatial and temporal profiles of phonon-polaritons are imaged onto a CCD camera using Talbot phase- to-amplitude conversion. This by itself was an extraordinary breakthrough. It was the first time that electromagnetic waves were imaged directly, appearing much like ripples in a pond when a rock plummets through the water's surface (see Fig. 3). Real-space imaging is the preferred detection technique in polaritonics, though other more conventional techniques like optical Kerr- gating, time resolved diffraction, interferometric probing, and terahertz field induced second-harmonic generation are useful in some applications where real-space imaging is not easily employed.
