PROFESSOR: OK, let us resume. I had no idea how many people would be here today, and I think I made 25 copies of the handout. And I see 25 names on the list. And that means that two people did not get a copy of the syllabus. Does anybody need a copy? That's strange. OK. All right. We covered some introductory material, and I think we've covered enough that you can do a problem set. So it gives me great pleasure to hand out problem set number one. OK, you can think about that. It is the sort of problem that will either take you two minutes or two hours or infinity. So don't spend too much time on it, but I would like you to put your name on it and turn it in either at the end of the hour or next time so I can make comments if there's something that's mostly right but not quite right.
