I want to know more about physics. In fact, I want to possess a physics Ph.D's erudition. The truth is, I blew it in my younger years....academically speaking. Given my financial and academic situation it is basically impossible for me ever to get back into college (unless I stretch it out for 20 years, which I don't want to do). My ultimate goal is to have a healthy understanding of both Quantum physics and relativity....perhaps even Ph.D level if possible. Is it feasible to become a self-learned physicist, or might I as well forget about it? If it's possible, what subjects must I study (minus extraneous liberal arts subjects for the time being)? I have a "general knowledge" of calculus (probably needs brushing up). My knowledge of physics is a combination of what I've learned from Naval Nuclear Power School and various Popular Science books (e.g. "Emperor's New Mind", "The End of Time", "Goedel, Escher, Bach", etc.). I am willing to follow any college's syllabus if I must and I am willing to pay the money for the appropriate textbooks. I just don't know where to begin. Thank you.
