In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves ...

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 ...

Ordinarily, light transmits the same in both directions: if I can see you, you can see me. Now, however, researchers have created a device that uses travelling sound waves to break this symmetry, ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

For the first time, physicists have discovered a way to levitate large objects—as in, human-sized objects—with an acoustic tractor beam. Researchers from the University of Bristol became the first to ...

A crucial building block for quantum computers based on sound has been shown to work for the first time. One popular way of building quantum computers is to encode information into quantum states of ...

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 ...

Students learn how sound waves are produced and transmitted. Students learn how sound waves are produced and transmitted and how frequency is related to pitch. The speeds of sound in different media ...

NOVA is excited to introduce a new pilot web video series devoted to asking and answering mind-blowing physics questions, big and small. In the coming weeks, keep an eye on the Receive emails about ...

THIS volume will be welcomed by those interested in the teaching of physical science, not only on account of its individual merits, but also as the first instalment of a complete treatise on physics ...
