Overview

Time pendulums, count cycles, measure lengths, graph data, predict frequency, calculate ratios, and even discover the square root of two. Couple pendulums with a rubber band to watch the energy flow back and forth. Join four pendulums with a raft of heavy books and watch the complex harmonic motion draw a seashell pattern. Great science, great math, great art, all done with simple materials.
