If i had to pick a text on physics to bring with me to the proverbial island, that would be, of course, Feynman‘s. If you’re thinking of (re)learning physics, those are the books to get. I’ve just discovered The Feynman Lectures on Physics Website, which contains stories, problems, errata, links (a pretty good collection) and even a forum devoted to these epoch making books. Enjoy!
