Physics Uncovered on Instagram: "This setup shows 15 independent pendulums, each slightly different in length. When released together, their small variations in frequency create a stunning visual mix of traveling waves, standing waves, beats, and moments that look chaotic—but every motion is completely predictable. The longest pendulum completes 51 swings per minute, while each shorter one swings just a bit faster, with the shortest (15th) making 65 oscillations per minute. As time passes, their
