These PowerPoint links are the same as each lecture. Each file is a
.pdf, and is quite large, approximately 2-9 mB. It takes a long time
to download them, even with a high-speed connection. You do not need
PowerPoint software to view the presentations.
If you print the slides two- or three-to-a-page, there will be room
to take notes, too. On Windows XP or Vista, select Print, and at the
bottom of the Print Window, you are asked "Print What?" Select
"Handouts (3 Slides per page)," or whatever you choose.
