Can we relate this to resonant frequency on our LBC's??  (made up LBC 
content)  :-)


Had to forward this.  For you physicists and engineers out there
Enjoy!

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.
