Remember from Mechanics that the period of a pendulum is proportional to the square root of the length of the line suspending the weight? Simply put, 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 ... sure it’s physics, but it's also art.
