Caltech posted online Feynman physics lectures

The best physics textbook of all time is now available online .

California Institute of Technology, where Richard Feynman had used a greater part of his career, laid out in the open access perfectly typeset lecture (formula displayed by MathJax). If you didn’t have physics at the university (or, as in my case, you weren’t on it), this is a great chance to catch up. All content, of course, is in English, but lectures are written in extremely simple language. It is also worth noting that so far only the first and third volumes are available; the second promise to lay out in the near future.
