Feynman's Lectures on Quantum Electrodynamics

Via DeLong, here are videos of the lectures by Richard Feynman that became QED.

Feynman gives us not just a lesson in basic physics but also a deep insight into the scientific mind of a 20th century genius analyzing the approach of the 17th century genius Newton.

For the young scientist, brought up in this age of hi-tech PC / Power Point-based presentations, we also get an object lesson in how to give a lecture with nothing other than a piece of chalk and a blackboard. Furthermore we are shown how to respond with wit and panache to the technical mishaps that are part-and-parcel of the lecturer's life.
