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

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 ...

The squeaking of sneakers on a gym floor is usually attributed to friction, specifically a stick-slip variety that involves cycles of sticking and sliding between two surfaces. But that model is best ...

The unofficial soundtrack of every basketball, squash or hard-court tennis match is the constant high-pitched squeak or shriek of the players' shoes. But can this squeak be designed out of them while ...

Over 8,000 people explored hands-on science experiments, from robotic arms to liquid nitrogen ice cream, at CSU's Little Shop of Physics open house.

Tiny, repeating detachments between sole and floor — thousands of times a second — create the distinctive squeak heard on the ...

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