The Skeleton Key of Mathematics: A Simple Account of Complex Algebraic Theories

Rating:
Summary: very helpful
Review: I used the chapter on Galois Theory as a reference for a course I was in because it had such a concrete explanation on how Galois Theory works. However, it didn't mention anything about field extensions & barely mentioned groups. That's why I liked this book, it gives concrete versions of things like (off the top of my head) complex variables, matrices, Galois Theory, polynomials, tensors & more. There's a chapter on each subject & treats it in a very concrete manner. Any math student not totally comfortable with abstractness (as I was, with Galois Theory of equations anyway) would find this book helpful, imo.
