Just a reminder about chapter 1 (up to page 40) for tomorrow (Tuesday).  We’ll meet at 12:30 in Hutch 316.  Dan S. wants to talk about grad student invited speakers for 10-20 minutes, so if you a) aren’t a grad student or b) won’t be here next year, you might want to wait until 12:45ish.  Concentrate on the preface and main argument and not the details of each example.
