Chaos, resonance, coupled motion — each lab below is a live canvas you can drag, tune, and record, built to make the underlying math feel obvious instead of abstract.
Click any card to open the simulation.
A pendulum hanging off a pendulum. Deterministic equations, chaotic motion — nudge the starting angle a hair and watch two runs tear apart. RK4 integration, draggable bobs, glowing trails.
The system that gave chaos theory its butterfly. Three simple coupled ODEs trace a path that never repeats and never settles — watch the strange attractor's two lobes form in real time.
Two perpendicular sine waves, drawn together. Tune the frequency ratio and phase to sweep through loops, figure-eights, and the tangled curves that give these patterns their name.
