In the guest blog, physicist Andrea Navarro-Quezada shows the importance of sound waves for our everyday life and research. Almost all of us know the concept of a wave. It is a periodic motion or ...

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.

Streams of sound are now all you need to make objects dance in the air and combine. A levitation device is the first to use high-frequency sound waves to bring together floating particles and liquid ...
