Hey all, as I just posted in my introductory post, I have completed by physics two semester non-calculus series. I have a rule for myself that I don't buy books on a given science subject until I've completed the introductory courses of that given type of science. Since I have, I have a question for you. What are the major foundations, or genres of physics. I want to continue to learn about physics, but would like to know what are considered the major fundamental areas. Thank you!
