In this section I'm starting to have trouble seeing how everything fits together, what implies what, etc. The vocabulary for rings and fields is starting to build up and become slightly confusing. With more exposure, and after Monday's lecture, I feel like most of it will make sense. It's just getting more difficult to visualize and keep things straight in my mind.
The most interesting thing to me about this section is theorem 3.9. If it is a field, it is an integral domain and then that it is only true that if it is an integral domain it is only a field if that integral domain is finite. I think the way that works out and how they proved it is cool.
