In this mesmerizing experiment, a row of pendulums is hung with lengths that differ only slightly. They all start swinging at the exact same moment, moving perfectly in sync at first. But as time passes, each pendulum drifts out of rhythm because of its tiny difference in length. Instead of chaos, something magical happens — a smooth wave appears, rippling gracefully across the line as if the p
