"This course combines computer graphics and dramatic reenactments of the history of science with introductory lectures by Caltech's David L. Goodstein. This in-depth adventure of the mind traces the interaction of ideas from Aristotle to Einstein to explain the theories of Copernicus, Kepler, and Newton. The programs clearly explain and illustrate classical mechanics and modern physics." . . "Torques and gyroscopes"@en . . "Program 19 explains and demonstrates Kepler's second law of angular momentum. Program 20 explores the effect of torque on a spinning object and how gyroscopes function. Uses computer animation sequences, historical reenactments, and close-up photography of experiments."@en .

Angular momentum: Angular momentum is a twist on momentum - the cross product of the radius vector and momentum ; Program 2. Torques and gyroscopes: When a torque acts on a spinning object the angular momentum changes but the object only precesses - why a spinning top doesn't topple." .
