Lesser known but possibly more relevant to most HN readers are Feynman's lectures on computation - https://theswissbay.ch/pdf/Gentoomen%20Library/Extra/Richard... . There's some really great explanations in there of computability, information theory, entropy, thermodynamics, and more. Very little of it is now out-dated.
> 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.
One of Feynman's funniest lines, I thought, was during a talk where someone in the audience asked if we'd ever be able to develop an anti-gravity device. Feynman gestured at their chair and said something along the lines of "we already have, in fact you're sitting on one right now."
