Sometimes, even the simplest things can set off a quantum phenomenon.

The new pump has no moving parts. “Instead, it relies on thermoacoustics, the interaction between sound waves and heat, to move thermal energy,” Interesting Engineering writes. The pump uses that ...

Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.

Exotic states of matter known as time crystals are largely considered a quantum phenomenon. Now, a team from New York University (NYU) has shown that a classical time crystal can emerge in a far ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...

Save your breath: A new way to make bubbles requires only sound waves. Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the ...

An array of miniature turntables could offer a powerful new way to control the flow of sound. The proposed device, reported in the March 20 Physical Review Letters, would channel sound waves in a ...

At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...
