Monday, September 16, 2013 - 02:55Sean Moss-Pultz: The Feynman Lectures on Physics (HTML)
Volume 1 of The Feynman Lectures on Physics is finally available in digital form, and in a format that doesn’t suck! (I hate PDF). If you’ve ever wanted to learn or relearn physics, nothing is better.
The special problem we tried to get at with these lectures was to maintain the interest of the very enthusiastic and rather smart students coming out of the high schools and into Caltech. They have heard a lot about how interesting and exciting physics is—the theory of relativity, quantum mechanics, and other modern ideas. By the end of two years of our previous course, many would be very discouraged because there were really very few grand, new, modern ideas presented to them. They were made to study inclined planes, electrostatics, and so forth, and after two years it was quite stultifying. The problem was whether or not we could make a course which would save the more advanced and excited student by maintaining his enthusiasm.
