The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes, beams ...

The treatment of kidney stones could soon be getting much faster, easier, and safer. Scientists have devised a method of ...

Research reveals how specific sound frequencies can affect you, with promising applications for pain management, stress ...

NASA teams on the ground at Mojave Space and Air Port in California used Schlieren photography — a process for photographing ...

The risk of tourism-related deaths there was considered too high to be acceptable to New Zealand society. This is also clear ...

In everyday materials, heat usually behaves predictably —it spreads outward from a hot source until it evenly distributes.

As a result, researchers are exploring new and novel ways to dial down the volume. They are turning to highly specialized materials and structures designed to buffer, baffle, and block sound waves.

For the first time, MIT scientists have successfully imaged how heat actually travels in a wave, known as a “second sound,” through this exotic fluid. Understanding this dynamic could help ...

MIT scientists have imaged heat traveling as a wave, called "second sound," in superfluid quantum gas. This discovery could unlock mysteries of neutron stars and superconductors.

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens.

Prior to 2003 a transatlantic trip from new york to london could be done in as little as 3 hours, compaired to today's fight ...
