🌀 Gyroscope Precession and Nutation: Heavy Symmetric Top, Angular Momentum and Steady Precession Rates (2D)

2D companion of the 3D gyroscope simulator: integrate the exact heavy-symmetric-top equations for a spinning disc on a pivot, compare the fast-spin precession rate m g l / (I w) with the exact steady-precession roots, and watch nutation, energy and angular momentum.
