A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials that allow air to pass through—like vents—also let sound escape, making it ...

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or ...

In a breakthrough that challenges conventional physics, scientists have confirmed the existence of “second sound” — a phenomenon where heat travels as a wave rather than dispersing slowly, as it does ...

“This project started with a simple question: why do basketball shoes squeak?” Adel Djellouli, a study co-author and ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...
