In this simple demonstration of how waves work, a Harvard instructor shows how a group of pendulums can move through a complicated dance together — due entirely to the way each pendulum oscillates at ...

Sixteen bowling balls strung from a wooden frame swing back and forth in unison, then in an undulating curve, then into seeming chaos before lining up once again. Each bowling ball takes a slightly ...

You've probably seen the famous pendulum demonstration—the one where the physics professor puts a bowling ball on a rope, holds it by her head, and lets it go, knowing it won't have enough energy to ...

Because a pendulum's oscillation frequency depends on its length, not its mass, you can use different colored bowling balls for a pretty effect. By Francie Diep Published Sep 8, 2014 7:20 PM EDT Get ...

We’re used to seeing pendulum waves generated on tiny scaffolds with itty-bitty balls. But as this awesome demonstration points out, the same physics applies even at the largest scales. The key to ...
