I graduated with a BA in Classicals and didn't take any math in college. Now that I've been out for a few years I find that I have an overwhelming desire to learn how things work in a way I can describe mathematically (it's hard to explain, hopefully you understand) and am starting some self study. Once I've gotten a good grasp on math I would like to tie in some physics as well, but I'm taking one thing at a time. I'm choosing Dover books because I get a lot for the money and I'm hoping they are accessible for someone who doesn't have experience with calculus or beyond but is willing to put in the hours to learn. So far I've decided to buy these books: Kline's Calculus, ODEs by Tenenbaum Linear Algebra Topology I would like to add one more book that would round out these subjects and that would build on them. I'm thinking about a book on Abstract algebra, but I don't know anything about the topic and am not sure if it is related. Should I think about a book on tensors or vectors? Maybe differential geometry? Real analysis? I'm interested in statistics too but don't see how this would fit in. I don't know enough to know how everything relates or builds off other topics. I'm well aware that to get through these books it will probably take me a couple years. I'm not in a race and I expect to be learning the rest of my life.
