At f/8, every lens produces an identical 10.7-micron diffraction blur on your sensor regardless of focal length or aperture ...

Scott Jenkins Particle size is a key parameter in many solids-handling processes, and can have a strong influence on product ...

Vladimir Zharov presents his vision for how to overcome the spectral, diffraction, and detection limits in spectroscopy, ...

The result extends an experimental history stretching back more than a century. Quantum jumps were theorized in the early ...

One of the physical properties of sound is its wave-like behavior. Diffraction, refraction, and interference are ...

Have you ever walked deep inside an office building, stepped into a basement café, or ducked behind a high-rise, only to watch your phone signal drop to a single bar or disappear entirely?In the ...

Stanford researchers have recorded the first real-time quantum jumps of sound, watching single phonons abruptly vanish from one energy state to another. The breakthrough could open new paths for ...

PRESS RELEASE — A Stanford team has documented the first direct observation of quantum jumps of sound in a mechanical resonator, completing an arc of scientific exploration that started over a hundred ...

Sound changes when a wall stands in the way, when you step out of a room, or when you enter water. AcousticSystem continuously reads the current world geometry, so placing or breaking blocks also ...

Thirty years ago, the blockbuster movie Twister featured a group of academics putting themselves at risk by chasing tornadoes in the name of science. Although the Hollywood story entailed a surfeit of ...

Researchers have generated high-quality atom diffraction data from graphene, which could lead to new ways to measure surface interactions. A beam of neutral atoms striking a material can produce a ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...
