Are you going to the Stephenson colloquium? Sounds rather brilliant--I've enjoyed his books, and judging by the transcriptions I've read of his talks he sounds an entertaining speaker.

I took Joan Cadden's seminar in mediaeval science my first year at Kenyon. She's quite a brilliant teacher; if it weren't that you're probably back at Yale by 6 february, I'd put in a rec for her colloquium as well.
