From today’s BoingBoing comes a post too intriguing not to share.
A demo of various lengths of pendulums (hmmmm … . wouldn’t that be pendula?), it’s on YouTube, followed by a series of similar demos. Some have music; others don’t. All of them are mesmerizing.
Here’s the description of the apparatus:
“The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period.
“The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations.
“Our apparatus was built from a design published by Richard Berg [Am J Phys 59(2), 186-187 (1991)] at the University of Maryland. The particular apparatus shown here was built by our own Nils Sorensen.”
Happy weekend, everyone. I hope the sun is shining wherever you are!
