Two identical tuning forks mounted on resonance boxes are struck with rubber mallets to show they have identical tones. A small piece of putty is added to one tuning fork to alter it's frequency. When ...

High school science teacher Sam Terfa wanted to demonstrate a fundamental physics principle: resonant frequency. To do so, he found the best singer at Minnehaha Academy and had him serenade a wine ...

Researchers have discovered how to control heat with a magnetic field. The study is the first ever to demonstrate that acoustic phonons -- the elemental particles that transmit both heat and sound -- ...
