Heat is not supposed to behave like this. In everyday life, warmth seeps and diffuses, spreading from hot to cold in a slow, smearing process that never looks anything like a crisp sound wave. Yet ...

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

Check one, two; check one, two; is this thing on? Over on The Public Domain Review [Lucas Thompson] takes us for a spin through sound, as it was in Britain around and through the 1800s. The ...

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 ...

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 ...

Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical substances. In Applied Physics Letters, by AIP Publishing, researchers from Nanjing ...

👉 Watch the video of Sarah’s science experiment at Young Women’s Leadership Academy Primary here! Hello parents, teachers and students! Sound waves are invisible but they create BIG energy. In ...

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...
