The Double Pendulum

A double pendulum consists of two pendulums attached end to end. When the first pendulum swings, it causes the second one to swing as well, creating a complex motion that can be unpredictable and chaotic. Unlike a simple pendulum, which swings in a regular pattern, the double pendulum's movements are highly sensitive to initial conditions, meaning small changes can lead to vastly different outcomes. This makes it a fascinating example of chaos in physics, showing how simple systems can produce unexpected and intricate behavior.
