Chaos Theory

Double Pendulum Simulation

Welcome to the Double Pendulum Simulator. This program visualizes one of the core ideas behind chaos theory: tiny differences in initial conditions can lead to dramatically different motion. Each pendulum starts with a slightly different first angle, so their paths may look synchronized at first before eventually separating into different trajectories.

Simulation

Use the sliders below to adjust the pendulum parameters, then press Run / Reset to rebuild the simulation with the new values.

Value: 30

Lower values leave a longer trail. 100 gives almost no trail.
