Talks

Warning: These slides from talks are in some cases very rough. Also, there are often important points that were made verbally in the talks but were not included on the slides -- the slides are not self-contained. So use with caution. Ignore the "Keynote" links unless you have that program and want to watch arrows fade in and out of existence.
