Does anyone know where I can find Feynman's derivation of the Universal Law of Gravitation?
You can't. Feynman never derived the "Universal Law of Gravitation".
Really? I heard that he did without using calculus, and I am interested...
"Richard Feynman, Nobel-prize winning maverick physicist, rederived such a proof (as have some distinguished predecessors."

I was just wondering if there was a resource online for this (rather than going out and getting the book).
Feynman started with Newton's Law of Gravity and derived Kepler's Laws, using his own geometrical arguments based on properties of ellipses. I don't know where you can find it online.
That is correct. The book is Feynman's Lost Lecture and is sold with a CD of the actual recording of the lecture by Feynman.
