  • An interesting video:
    Conservation Laws in zero gravity (Skylab). Around 10min, there is a demo of a rotating bottle switching rotation axis to the one with larger moment of inertia. Explanation follows, but stated simply: KE = L^2/2I. The KE decreases due to some friction but there is no torque, so L is constant and I has to increase. So the rotation axis changes to increase I.

  • A useful diagram for understanding the Precession of the Equinoxes
