Feynman Lectures on Physics Vol. 1 Released in HTML Format
Dr. Richard Feynman's lectures on physics have been iconic standards of physics education for the past five decades. Videos of the series were put online at Microsoft Research a few years ago, but now the entirety of Volume 1 is available over simple HTML (mirror). In a letter to members of the Feynman Lectures Forum, editor Mike Gottlieb said, "It was an idea conceived many years ago, when through FL website correspondence I became aware of the many eager young minds who could benefit from reading FLP, who want to read it, but for economic or other reasons have no access to it, while at the same time I was becoming aware of the growing popularity of horrid scanned copies of old editions of FLP circulating on file-sharing and torrent websites. A free high-quality online edition was my proposed solution to both problems. All concerned agreed on the potential pedagogical benefits, but also had to be convinced that book sales would not be harmed. The conversion from LaTeX to HTML was expensive: we raised considerable funds, but ran out before finishing Volumes II and III, so we are only posting Volume I initially. (I am working on finishing Volumes II and III myself, as time permits, and will start posting chapters in the not-too-distant future, if all goes as planned.)"
MathML for equations and SVG for diagrams. This is a quality transcription from the book to online.
They have the agreement of the print publisher to produce this free online version. I'm actually somewhat surprised they got it; as the summary notes, they had to convince the publisher that having a free version available online wouldn't hurt print sales, which is often hard to convince publishers of.

In addition to being a great physicist, Richard Feynman was also quite funny and a pretty big troublemaker in his day. What a great guy. If you get a chance, the book "Surely You're Joking, Mr. Feynman!" is well worth the read.
Feynman was known for his contributions to physics, for communicating concepts clearly and in an interesting manner, as exhibiting certain traits known as "being human".
Now there are physicists who did far better in each of the three areas than he did, but very few (if any) did as well as he did in all three areas.
Nah, that's Einstein. He got lucky once and stole Olinto De Pretto's formula, but after that? Feynman was working all the time.
De Pretto figured out (or perhaps made a lucky guess) based on his understanding of the lumineferous aether. Einstein derived it from his special theory of relativity. Einstein presented E=mc^2 in a followup letter to his paper "On the Electrodynamics of Moving Bodies" (i.e. it's an interesting derivation, not an essential part of the theory). There was also the photoelectric effect and general relativity. Of the three, special relativity is arguably his least impressive work (Lorentz, et al, were also working towards it).
No. Not over-rated. He was capable of communicating ideas, deep and otherwise, clearly, which is very difficult. Consider how to convey the difference in magnitude between gravity and the electromagnetic force. The example he gives goes something like this:
RF: What is your charge right now?
Student: neutral.
RF: Why?
Student: Because we have the same amount of positive and negative charge.
RF: OK. What would happen if you took some electrons from your neighbour?
Student: I would become positive and he would be negative
RF: Yes. Now I want you to imagine you steal some of the electrons from your neighbor. Let's not be greedy. Let's say you take 10% of them. Now you are negative and your friend is positive and you will feel an attractive force towards him. The question is: how strong is the force of attraction. Is it larger or smaller than the weight of the Empire State Building?
Student: Hmmmm...dunno. I'm gonna guess larger.
RF: Yes it is larger. But how much larger. Is the force of attraction between you and your neighbor larger or smaller than the weight of Mount Everest?
Student: I'm gonna go with larger.
RF: Yes, you are correct. In fact, the force of attaction between you and your neighbor WILL BE ABOUT THE SAME AS THE WEIGHT OF THE ENTIRE EARTH!
The above paraphrased lesson emphasizes like nothing I've ever heard before how weak gravity is and how strong the electromagnetic force is. Simply brilliant.

True. But for clarity I much preferred Lenoard Susskind's Stanford lectures, which are available on YouTube.
Hi. I teach undergraduate physics. If you're a clever high school or early college student interested in physics, you may have heard of Feynman, and you may have heard physics people give rave reviews of the Feynman lectures. And hey, he intended these lectures as a first-year college physics course, so that's perfect for you, right?
Wrong. This is not the right place to start learning physics. Feynman has some beautiful insights about how introductory physics concepts connect to "real" modern physics, and a way of cutting through the red tape to elegantly explain concepts in ways that make experienced physicists drool. But that's not what you need. You need the red tape. You need to learn to apply concepts to real situations, you need to get buried in the algebra, trig and calculus and dig your way back out again. Feynman won't help you about that.
Feynman's Lectures on Physics represent how an experienced modern physicist would teach introductory physics to a roomful of other professional physicists. Feynman was a genius, but his lectures are designed to impress, not to teach. You should absolutely read it, and you will love it, later in your career. But start with a more traditional textbook.
