Legendary "Feynman Lectures On Physics" Are Available For Free

Woohoo! Caltech has put the Feynman Lectures On Physics on a website for anyone to read for free. Maybe it has been up for awhile and I just hadn't noticed till now. When I was in college, I shelled out a lot of money for paper copies of all 3 volumes. I have hauled them back and forth across the USA on all of my moves since.

There are many virtues to these lectures. If you are bored in a more conventional introductory physics course, these lectures offer a different perspective, exposition style, rigor, and even topics than any of my other first year physics books.

One thing I love about these books is the cool side-chapters on topics that were not covered in my intro courses. A good example is The Mechanics of Seeing.

You can find some of the problem sets, that originally accompanied the lectures here.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Apart from the Lecture Notes, there are also Audio Lectures of Feynman himself giving lectures to people at Caltech...
I have all the 3 volumes in PDF as well as the Audio lectures....Its a shame that they didn't put up video lectures..anyway, thanks for the info.

I'm guessing video does not exist. I don't think that it was commonplace to have video cameras in classrooms in 1961-3, even at Caltech.

I too have this book it's an amazing book . The way he starts things from basic to the higher level is fantastic !

Yes really think this is a good book to learn physics especially if you have the math.

No wonder why I was sometimes struggling with the book :).

And thanks sir for sharing the links. All this while I too have borrowed them from the library (pretty uncomfortable to carry).

Yeah that is a good point. People should be warned that you have to be extremely comfy with calculus to get the most out of the book. Other things like probability he does a really good job of explaining in the context of the physics he want to talk about.

Yes! The exercises on that website are also great for those who are looking for a physics challenge (aside from Brilliant, of course).
