Physics you can orbit.
Black holes spiralling in, a galaxy of up to 2,000 stars, smoke rings that leapfrog, a wave packet meeting a barrier, a magnetic bottle and a running crack. Each one computes in your browser and puts its numbers on screen: drag to orbit, change the inputs, watch the readouts.
Simplified browser models for intuition, not physical validation; each page states what its numbers come from. The chaos and consumer-hardware audits moved to Evidence.
