A group of international researchers have developed a way to use sound to generate different ... while other patterns caused the objects to move along circular or spiral paths.” ...

Levitating objects can spin, glide and collide together — no magnets or magic tricks required. Using steady streams of sound waves, engineers maneuvered hovering toothpicks, coffee granules and ...

Physicists have taken direct images of heat moving in a wave-like manner in a phenomenon known as "second sound" for the ...

Intertwined short vortices of sound waves moving in opposite directions would ... Caleap and his team built a single-source, circular array of transducers, or speakers, that generate ultrasound ...

First theorized in 1938, heat's wave-like flow through superfluids, known as "second sound", has proven difficult to directly ...

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...

Others cause the balls to spin about on their centres and move precisely along a circular or spiral path within the patterns. Unlike ordinary ripples, these wave patterns remain stable even when ...

Semi-circular canals To help you balance. They play no part in hearing. How we hear: a sound wave is funnelled into the ear canal by the pinna the vibrations in the air make the eardrum vibrate ...

When an earthquake creates sound waves that travel upward through the atmosphere, the upper parts of the waves move faster than the lower parts. This makes the wave front lean or tilt as it moves.
