Some physical systems — such as the atmosphere, a geomagnetic dynamo, or a simple electronic circuit — follow entirely deterministic laws, yet behave unpredictably over the long term: tiny differences in initial conditions amplify exponentially over time (the famous "butterfly effect"). When this occurs, the system's trajectory in state space does not disperse randomly, nor does it collapse into a fixed point or a simple periodic cycle. Instead, it winds around an intricate, self-similar geometric structure known as a strange attractor.
StrangeAttractors is a computational laboratory that generates candidate systems of differential equations, simulates them numerically, and rigorously verifies whether they produce deterministic chaos — distinguishing true chaotic dynamics from trajectories that simply diverge, decay into a fixed point, or follow non-chaotic periodic orbits.
Here are some systems I found using the site:
