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.

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

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.

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).

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

Apart from the Lecture Notes, there are also

Audio Lecturesof 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.

Thankyou Sir.

I knew about this one!!!!! Can you please share some more good books(or lectures) on Physics and Mathematics which are available for free??
