Hello everyone, and first of all I would like to clarify that I don't think I'm asking a regular "how do people do physics" out of frustration. I am really interested in physics and I've joined a university for my Under Grad Physics course, and I want to go beyond what my course teaches. Is there any way by which I can learn a lot(I know I have to put a lot of work, of course, but i feel that I have no one to guide me, at least at this point of my life), I mean what books do I have to study and how do I study them to get a great knowledge of Physics. Can someone guide me through my productive years of my life? Thanks in advance. P.S.:I dream of becoming a theoretical physicist or maybe an astrophysicist.
