My version of 123 did not deal with non-commutative rings. But Galois theory is awesome enough to make it a good course. I am, at heart, still an algebraist, and group theory is very near and dear to me. Some of these modules and polynomials and stuff however get way too close to number theory for me to feel comfortable with them. It just isn't pretty.

If I remember, I will bring my Penrose up to Vericon.

Note: Penrose is not a Com Plex Analysis book, not any other textbook. It is a physics book for laypersons. The first half of this 1200 page book tries to teach someone with a Folk&Myth degree all the math that they need in order to understand physics. And by physics, I means string theory and beyond. He does a nice job of explaining a lot of the major theorems and how they relates to each other, without getting bogged down in the detail of proof.
