Hi, I am going to start from Zero in theoretical physics, and have no chance to study it in a university now, so I will do self-study until I can do graduate study in physics, I am an EE so I have background in physics and maths. so, please I need someone to help me with the following: - field in maths and physics I should build a strong background in. - book name (best) in each filed. - a path to take in such self-study program, which to do first and so on. thanks.
