The Feynman Lectures on Physics are now available to read online. They are a great collection of lectures covering physics and touching on many areas including: the Mechanisms of Seeing, Semiconductors and Algebra. This is a fantastic resource for learning about physics.
You can also get a boxed set of The Feynman Lectures on Physics for those that like paper. It is fantastic but not cheap.
Bill Gates bought the rights to the rights to The Character of Physical Law, 7 lectures Feynman gave at Cornell University (these are separate from the lectures listed above) and made them available online, which is great. Unfortunately the website is based on Microsoft tools and therefore quite a bother for many (or maybe even impossible with Linux computers – I am not sure). I guess since he made all his money via Microsoft it isn’t that surprising but it would have been nice if he provide the content in a more easily accessible way (even if they didn’t do the fancy additions they did on the Microsoft site. These are great enough videos to probably be worth the bother of installing proprietary Microsoft software in order to view them.
