The Feynman Lectures on Microsoft Research

Seven famous lectures given by Richard Feynman at Cornell University in 1964 are now completely available on the Microsoft Research Website as part of Project Tuva. Richard Feynman "was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model). For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga." Wikipedia.

Project Tuva is an enhanced video player platform initially built by Microsoft Research to host The Messenger Lectures given at Cornell University by Richard Feynman in 1964 and recorded by the BBC. This was a collaborative effort between Bill Gates and Microsoft Research which is designed to demonstrate the abilities of enhanced video to teach people about the "core scientific concepts" of Feynman's lectures using interactive media.
