Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a ...

This new high-tech system puts out fires using sound waves. The revolutionary technology could help protect homes in high ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

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 ...
