Produced by the California Institute of Technology and Intelecom, and made available by Annenberg Media, The Mechanical Universe ... and Beyond is a collection of 52 half-hour videos covering many important topics in physics. The purpose of the this video series is to help teachers demystify physics using "field trips" and computer graphics to illustrate abstract concepts. Some of the topics covered are falling bodies, vectors, forces, the conservation of energy, resonance, angular momentum, electric circuits, magnetism, Maxwell's equations, optics, Lorentz transformation, entropy, and quantum mechanics.
Created by Henry Reich (Perimeter Institute for Theoretical Physics), Minute Physics is a YouTube channel. It contains a growing collection of short videos that explain and distill important concepts in physics.
