> However, we want to be clear that this edition is only free to read online, and this posting does not transfer any right to download all or any portion of The Feynman Lectures on Physics for any purpose.

I'm not entirely sure how to read this in my web browser without it being downloaded in the process.

It would be nice to get the audio released free as well. While not as useful as the books for actual learning (at least half of the audio is Feynman drawing furiously on a chalkboard and booming "and then this leads to this...") much of the beginning parts of each lecture are dedicated to well spoken overviews and ideas, and to hear them from Feynman himself is quite amazing. I've only been able to find some of the audio files for sale on Audible and on some rare bootleg torrents.

Old but always immensely valuable .. Feynman is a huge scientific hero of mine

This has been free for quite a while already. I've been referencing this online edition since at least 2014.

This is huge! Highly recommend reading along to the audio if you can find it.

This is some years old, in case that's not clear, and "free" as in readable online at no charge. There was an interesting account of the production process somewhere, but I can't find a reference to it.

Is this a nice way to finally catch up on physics for someone who never got much of it in high school? Or would Khan Academy still be preferable?

Note: Web access only, no downloads.

Is this since 2013?

Tried to access on HTTPS, only to get https://scriptshadow.net/wp-content/uploads/2014/02/canary-i... on a page by itself. WTF?

when will the feynman lectures expire? I think they are great, but it would be nice if it had more references to sources.

Is it just me or all the images are broken?
