I'm a pure mathematician working in Ricci flow, Einstein manifolds, and Yang-Mills, with no physics background. I'd like to learn advanced theoretical physics such as quantum field theory, string theory, and supersymmetry. However, the standard books in these areas have very strong physics assumptions on the background of the reader, so they are inaccessible for a pure mathematician with no physics background.
Furthermore, after getting some way through mathematics, one realises that working through the big thick 1,500 page calculus textbooks is unnecessary since they are targeted at engineers. Instead, one can start with books on set theory, logic and proof, and then go straight to pure mathematics books in analysis, abstract algebra, topology and geometry, etc. I wonder if it's the same situation with theoretical physics: does one really need to start with working through one of those 1,500 page physics for scientists and engineers textbooks, or is there a better path?
Question: As a pure mathematician with no physics background, how do I learn the basics through to advanced theoretical physics in a clear, focused, streamlined and structured way?
Can someone please outline a path of study, with specific book recommendations, to achieve this?
