Each room opens with something that shouldn't happen — a wheel that won't fall, loudness that adds up to silence, current conjured from motion, a curve with no force behind it, a film that only plays forward. Then it hands you the controls. The equations arrive last, once you've already seen what they say. Take the rooms in order or wander; each stands alone.
The Wheel That Refuses to Fall
Rest a spinning wheel's axle on a post and it circles calmly instead of crashing down. Nothing visible holds it up. What redirects the fall?
Gyroscopic precession ⟶
Where Two Waves Make Silence
Two loudspeakers, both blasting — and stripes of dead quiet across the room. How can louder plus louder equal nothing?
Interference & standing waves ⟶
Current from Nothing but Motion
No battery anywhere — yet push a magnet toward a coil and current flows. Stop moving and it dies. Where does the push come from?
Electromagnetic induction ⟶
The Curve That Isn't There
Long-range shells land east of their targets and hurricanes all spin the same way per hemisphere — deflected by a force that, seen from space, does not exist.
The Coriolis effect ⟶
Why Time Has a Direction
Every microscopic law runs the same backwards as forwards — yet cream never unswirls from coffee. What chooses the direction, and why can no engine escape its tax?
Entropy & the Carnot cycle ⟶How this exhibition was built. Every interactive experiment integrates the genuine equations of motion in your browser, live: the heavy-top Euler–Lagrange equations (RK4) for the gyroscope; the 1-D and 2-D wave equations by finite differences for interference and standing waves; exact dipole flux with Faraday's law and a galvanometer ODE for induction; free-body and rotating-frame equations, cross-checked against each other, for the Coriolis room; 340 elastic hard disks and exact gas-law strokes for entropy. Each page displays its own integrity checks — conserved energy, theory-vs-simulation overlays, bookkeeping identities — so you can watch the physics audit itself. Photographic imagery and the two film clips are AI-generated illustrations (Nano Banana & Veo 3.1 via the KIE API); they set the scene, while the simulations carry the truth. Everything runs offline from these files. Built by Claude (Fable 5), July 2026.
