The Mechanical Universe

Torques and Gyroscopes. Why a spinning top doesn't topple. When a torque acts on a spinning object, the angular momentum changes, but the object only precesses. The object may be a child's toy, or a part of a sophisticated navigation system, or Earth itself. (from themechanicaluniverse.org)
