neelk and I went through a few sections of Chapter III of Paul Taylor's "Practical Foundations of Mathematics". Don't let the title fool you. It is actually "Rewriting Most of Mathematics in Terms of Categories", which I heartily approve of. Especially when it's posets ~ them things are just categories that can't tell one arrow from a hole in the ground. I mean, uh, from another arrow.

Also did music in the morning with iole200 and gustavolacerda guest-appearing on the guitar. Fun as usual, although I notice my sense of being able to follow what is going on musically gets a little bit shaky as the number of people increases. A good thing to practice, I guess.
