For more than 50 years, scientists have dreamed of seeing the hidden patterns that govern the motion of nonlinear waves—the ...

On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

In 1806, German scientist Ernst Chladni experimented with sound by making wires, columns of air, and solids vibrate. His experiments became so famous, even Emperor Napoleon Bonaparte wanted to know ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we may ...

The program explores the nature of mechanical waves, questioning how they move and what creates them. It demonstrates wave motion through various experiments, including using a slinky and a wave ...
