My First Lecture

I apologize for a rather boring first lecture. Presenting this textual material in an interesting way is always a challenge, and I felt I didn't rise to the challenge yesterday. Nonetheless, we'll carry on, but in the near future I may begin posting some of these notes rather than present them in class. Let me also take this opportunity to remind you about the little exercise I posted on Tuesday, Sept. 2nd. You need to respond to it by next Friday, Sept. 12th.
