Physics & patternsDouble Pendulum
How long do two double pendulums started 0.1° apart swing together?Two double pendulums start with their upper arms 0.1° apart. Their lower bobs move together for about 7 simulated seconds, then separate completely.
Physics & patternsSpring Chain
How long does a tug on the middle bead take to reach the pinned ends?Eleven beads on ten springs, both ends pinned. The center bead starts 5 units up; its pull reaches the beads beside the ends after about 40 ticks, and the chain keeps swinging.
Social dynamicsAudience Applause
Why can slowing down help a crowd find a shared beat?96 clappers, each pulled toward the crowd's average beat. At the slow tempo, where preferred rates vary less, the hall locks onto one beat in about 4 seconds; at double speed it doesn't.
