Physicist Richard Feynman was particularly famous for his lectures, which were known for being an engaging and accessible introduction to a number of scientific topics. Now Volume One of The Feynman Lectures is available in its entirety online.


Videos of several of Feynman's lectures are already online, but now Caltech and The Feynman Lectures Website have made the text of the first volume of his textbook, authored by Feynman, Robert B. Leighton, and Matthew Sands based on the lectures Feynman delivered at Caltech, for free. Huge thanks to everyone involved for making this valuable work more accessible to the general public.


The first volume is 52 chapters long and focuses mainly on mechanics, radiation, and heat. The team that brought us this volume also hopes to bring us Volumes 2 and 3 at some point in the future. In the meantime, dig in!
