On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

👉 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 ...

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 ...

Mechanical engineers have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as 'acoustic tweezers, ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

"We don't need to go into space to do these experiments anymore." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Physicists have replicated the ...

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 ...

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”.

In 1806, German scientist Ernst Chladni experimented with sound by making wires, columns of air, and solids vibrate. His experiments became so famous, even Emperor Napoleon Bonaparte wanted to know ...
