Hello, I am new to this forum, but have read a lot of posts and it seems really cool. I am 38 and have a B.S. in mathematics (from many years ago). I work in insurance, so I am pretty far removed from acedemia now. I have kept up my math studies as a hobby. After studying a lot of theoretical math, it has become really abstract and I am interested in learning how to apply it. I would really like to learn about general relativity. Just to satisfy my own curiosity. I completed a year of undergraduate physics in my college years (calculus based), but except for pop sci books, that is my only real physics exposure. As far as math goes, I have completed analysis, abstract algebra, linear algebra (theoretical level), and Spivak's Calculus on Manifolds (in addition to a basic math major's requirements). I am well versed with my math up to this level. The freshman physics I completed was interesting, but not challenging. Just some computational stuff. I would really appreciate any suggestions on where to take my studies into some real physics. Any suggestions about further math to study, but especially physics to get a real understanding of what is needed to explore general relativity would be awesome. I have no intentions/illusions about becoming a physicist (just a hobby), but pop sci books don't really do it for me. Again, this is just a hobby, but I don't like to water down my studies. Any suggestions on study materials, especially ones with answers, so I know I am not incorrectly interpreting things would be great. Thanks in advance!!
