Simple Harmonic (and non-harmonic) Motion

This is one of those random emails that came to me. I'm passing it along before I file it under Fun Facts to Know and Tell.

The scientific explanation notwithstanding, this is some neat stuff to watch!

Harvard built a device with a series of fifteen pendulums in a row, each one of them slightly longer than its neighbor. 
The pendulums were set into motion and the result was captured on video. 
The patterns that appear in this short video are fascinating to watch. 
Prepare to be captivated by this simple device!

That is very cool. I know science has a complete explaination for it. But I perfer to think it's magic.

I love that. It looks like one of those things you often find on an executive desk. Wonder if that would work the same way. You usually see people hitting one end to set the pendulums in motion, not the way it's shown in the vid. Worth a try (except I don't have one).

I like the bits where the pendulums seem to be random and then reset themselves for the next pattern. Thanks for sharing!

How cool is that?!? It's a wonder they don't get all tangled up. Wouldn't it be fun to have one in your living room. Who would need tv?
