Caltech: The Feynman Lectures on Physics

The Feynman Lectures on Physics

This is the best thing I’ve found, on the Internet or elsewhere, for a very long time.
Richard Feynman was an incredible human.  His abilities as an educator were second to none and his lectures, no matter the topic, have become a matter of legend.  Caltech has partnered with The Feynman Lectures Website and published The Feynman Lectures on Physics, in HTML and have made it available to the public for free (the hardcover version can be bought from Amazon for slightly north of $180).

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.
