Really? I heard that he did without using calculus, and I am interested...HallsofIvy said:You can't. Feynman never derived the "Universal Law of Gravitation".
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.apmcavoy said:Does anyone know where I can find Feynman's derivation of the Universal Law of Gravitation?
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.Doc Al said:Feynman started with Newton's Law of Gravity and derived Kepler's Laws, using his own geometrical arguments based on properties of ellipses.
