David Feinstein, applied mathematician and former TA for Feynman at Cal-Tech, delivered his presentation about truth and certainty this afternoon (yesterday afternoon by now). I was one of the group leaders (shop talkers) at a table for high school aged competitors from all over the world (Cleveland, Alaska, Malaysia etc. at my table).
Later, I looked around at the exhibits (still being set up -- open to the public starting Thursday). This contraption solves a Rubic's Cube -- a computer driven device.
At dinner later, in the huge Convention Center ballroom, I met a patent attorney from Munich -- this was his first visit ever to the US, though he'd traveled in Asia and South America. I invited him out for beers (we took public transit over to my neighborhood) then drove him back to his hotel. We had a fun time comparing notes.
