There was a nice turnout for my lecture last night at UC-Berkeley (in Giannini Hall, above) as part of the 2009 Breakthrough Seminar Series. Lots of good discussion as well. At the talk I met Tom Fuller, who has posted up some comments
about the talk. And I understand that a streaming video will be online before long. Meantime, you can download my slides here in PDF
. Comments welcomed.UPDATE 7/3: More form Tom Fuller here. And here. And even more here.
