Spoke at U Tennessee Wednesday to mix of locals and students and faculty. Maybe 250. Went 75 with 15 Q&A. Bit sloppy on my phrasing, and like so many college audiences, this one pretty serious and wouldn't laugh too much. Afterwards met parents-in-law of David Granger, editor-in-chief of Esquire. They said "our little David" hasn't changed one bit since leaving the volunteer state, and that makes them all the more proud of his achievements. That was kinda cool and unexpected! Naturally, I praised David to the hilt, because he's been a great influence on and promoter of my work. After the talk, I go about an hour with a class who had read PNM for their globalization class. That was a lot of fun. Then a working dinner in Oak Ridge at the lab, then all-day meetings today. Just a 2-day, 1-night trip! Pure heaven.
