Waves on the pendulum
Way cool video!
You may recall from a Mechanics course that the period of a pendulum is proportional to the square root of the length of the line suspending the weight - i.e., the longer the pendulum, the slower it swings. Harvard students built a device with a series of 15 pendulums in a row, each one slightly longer than its neighbor, then set them in motion and filmed the result. The resulting patterns in this short video are quite fascinating to watch. - Simple Harmonic (and non-harmonic) Motion § Harvard Natural Sciences Lecture Demonstrations |
You tricked me into staring at some guys dangling balls!

Yea, but they are really cool! The patterns they make are amazing.

That's one of the coolest things I've seen on youtube!

Cool!

Very interesting. Thanx!

That was really cool to watch. Thanks!

Very cool. It kept my 5YO mesmerized......for a bit.
I bet that would be trippy if one were to be feeling a little tipsy. :) |
