i am looking for Feynmans Lectures on physics. that book is the reason i got into that type of science. i was only 16 when i read it, but i didn't understand any of the equations in it. but now that i am more advanced in the subject i want to give it a try again. the only bad part is that the entire 3 volume set is like $156, which is an insane price. i might as well go back to the library and just check it out like i did when i was 16. but i would really love to own it, so does anyone know where i can get the entire 3 volume set for a good price?
