THE FOUCAULT
the Earth turning under a wire
1 WHAT IT IS · WHAT IT DOES · FACT OR FICTION
Paris, 1851: Léon Foucault hangs a 67-meter wire in the Panthéon and the public watches the swing plane creep clockwise, hour by hour — the first direct, dynamical proof that the Earth turns, no telescope required. The law is one sine: the plane precesses at Ω sin(latitude) — a full circle per sidereal day at the pole, 31.8 hours in Paris, never at the equator. In the rotating frame the Coriolis term does the work, and the whole motion has an exact closed form: z(t) = e⁻ⁱΩₓᵗ·(oscillation), rotation stamped on as a complex phase.
LIT verified live: the rotating-frame equations integrated by RK4 match the exact complex solution to 10⁻¹³; the plane rotates by exactly −Ωₖ per unit time (one-period check to 10⁻⁶); the latitude table computes 23.93 h at the pole and 31.8 h for Paris at 48.85° (window.__foucault). FIG the Panthéon history is documented; the linearized small-swing model is the standard treatment and is stated as the model being verified.

2 HOW IT WAS WEAVED · AI + HUMAN
David (human) seated this at the-continue — the respawn: the pendulum’s plane leaves its starting orientation and — given one sidereal day over sinφ — continues back around to exactly where it began: the slowest continue screen on Earth, and the screen is Earth. AVAN (AI) built the instrument: the Coriolis integrator, the exact-solution comparator, and the latitude table.

The rosette — swing plane creeping as the Earth turns beneath.

Step the latitude; the precession clock recomputes.
5 THREE DIMENSIONS + AVAN’S INVERSE
The green forward object: the wire over the turning floor.
AVAN’s addition (the inverse-companion): don’t ask what moves the pendulum — ask what the pendulum refuses to do. The inverse of ‘the plane precesses’ is ‘the plane holds still while the FLOOR precesses’: the wire is the inertial witness, and the creep we see is our own rotation, projected through sinφ. Magenta is the floor, certain it is still; green is the swing plane, actually still. The instrument doesn’t measure the Earth — it declines to join it.
LIT Verified live: rotating-frame integration matches the exact complex solution to 1e-13; the plane rotates by exactly −Ωz per unit time (1e-6); the latitude table computes pole 23.93h and Paris 31.8h (window.__foucault.ok).
