Chaotic Pendulum 01.13

This exhibit demonstrates chaotic movement.

A double pendulum is a simple but effective demonstration of chaos theory. Each time the system is started, a different sequence will emerge —the pendulum moves in different unexpectable ways; rotating left or right, or swinging. This is due to tiny differences in the initial configuration. Chaotic systems exhibit a property called sensitivity to initial conditions. That means that no matter how exactly you tried to duplicate the initial angles and velocities for each experimental run, the motion would soon be very different from experiment to experiment.

  1. Turn the knob as fast as you can.
  2. See how the pendulum swings.
