Lately, I realized that I've grown tired of calculations and want to venture into more theory type books although I haven't taken any proof based math classes yet. I feel confident that I can do basic proofs, i.e. the "show that" type problems but nothing too crazy after that. I've read through a chunk of Boas' book and it's great to show how to calculate but I definitely don't understand how things are working. I've taken linear algebra, Diffy Q, Calc 1-3, and I'm just finishing up a class on special functions and advanced DE techniques. Also, I've just taken intro physics 1 and 2 but have learned a tiny bit of upper level physics on my own. Anyway, I want a book that shows the math of physics without getting too proofy or require high level physics knowledge. The closest book I've found is "The Geometry of Physics" by Frankel but reading through the table of contents is very intimidating because I literally don't know anything of those topics before: manifolds, bundles, forms, etc. Although, according to the preface, my background does meet the requirements for the book. Anyone else use this book? Ultimately, I want a book that shows the math for itself but then applies it later on to physics. Also, I'm very visual and need pictures to understand almost anything. I will be self studying from the book as well. Any suggestions? Thank you.
