My last encounter with Richard Feynman was not long before he died. Richard and Carl ate dinner with Julie and me at our house. We spent the rest of the evening practicing lock picking with locks from my rather extensive collection. I still sorely miss my friend, Richard Feynman. When thinking about interesting ideas, from either physics or computation, I often ask myself, "What would Feynman think of this?" -- Gerald Jay Sussman, MIT AI Lab, co-author of SICP
