Thanks to Caltech:
Caltech and The Feynman Lectures Website are pleased to present this online edition of The Feynman Lectures on Physics. Now, anyone with internet access and a web browser can enjoy reading a high-quality up-to-date copy of Feynman’s legendary lectures. This edition has been designed for ease of reading on devices of any size or shape; text, figures and equations can all be zoomed without degradation.
So far, they have only published Volume I (mainly mechanics, radiation and heat), but they “hope to eventually publish Volumes II and III”.
You have good reading stuff until then, I guess. Enjoy!
