My brother teaches middle school social studies, a job that requires him to give lots and lots of feedback. Some of it is called grading. A big part of his job is to teach kids to do a careful ...

Researchers deserve a round of applause for uncovering the science behind the acoustics produced from hand clapping that had not been clearly understood until recently. The daily gesture that people ...

Hand clapping is ubiquitous behavior for humans across time and cultures, serving many different purposes: to signify approval with applause, for instance, or to keep time to music. Acousticians often ...

Clapping is both a scientific event and a social gesture. A study explores the complex physics behind the sound of clapping. The noise originates from compressed air, not just hand collisions.

Researchers elucidate the complex physical mechanisms and fluid dynamics involved in a handclap, with potential applications in bioacoustics and personal identification, whereby a handclap could be ...

ITHACA, N.Y. — Every time you applaud at a concert or celebrate a touchdown, your hands are performing a feat of physics that scientists have puzzled over for decades. Cornell University researchers ...
