I watched a chaos pendulum swing on a video. A mesmerizing dance of physics and fate. Two arms joined in sequence, each free to rotate fully around its pivot point. Unlike a regular pendulum that swings in predictable arcs, this double pendulum moves like a dancer gone mad. The first arm influences the second, which in turn affects the first, creating feedback loops of motion that defy prediction.

They released it twice from what appears to be the exact same position. The first time, it traces an elaborate pattern through space. The second time, from a starting point just millimeters different, it carves an entirely new path. The result is pure chaos.
