PS One of my Profs went to the Swedish Royal Academy as an undergrad. One perquisite is that you got to listen to the Nobel Laureate lectures. He was there for Richard Feynman's lecture. Feynman was writing out equations on a chalk board for the assembled dignitaries when he stopped and walked off the stage. About 30 seconds later, he walked back onto stage and wrote down a number. He then turned to the audience.
