The Feynman Lectures: Online

It turns out, Caltech has made the Feynman Lectures available online on their website.

Not only is the complete content of the original lectures available, but also some additional and supplementary material, such as “Feynman’s Tips on Physics”, photos, sound and video recordings, and even Feynman’s own handwritten notes.

The editors have also done an extremely nice job retaining the “look and feel” of the original printed version of the Feynman Lectures in this online edition — for immediate visual recognition.

The material is not available for download, only for online reading. But the online experience is indeed so good, that it very well stands in for printed books.

Thanks to Caltech for making this material freely available, and for the care and quality of the rendering!
