I have a class that teaches how to think in mathematics i.e. read and write proofs. Right now the professor decided to deviate from the text and teach field theory which is really confusing to me since I am am Biochemistry with a math minor so I'm mostly learning applied math. I never encountered this before and its not easy to understand.
I couldn't find any good resources to supplement the professors material. Can someone tell me some sites or books that can help?
