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, ...

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 ...

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating cycles, even without a steady external push.

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

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 ...

Soil is one of our most precious resources. Ecoacoustics, or the study of environmental sounds, has been around for a century, but it has only recently been applied to understanding soils. This ...

Concordia researchers have developed a new 3D-printing technique that uses sound waves to directly print tiny structures onto ...

This experiment demonstrates how water affects sound waves and pitch. You'll discover how different water levels create different musical notes and learn about the relationship between mass, vibration ...
