Doing my bit to get this little vignette added some day to a learned biography of Frank Wilczek:
Me: (sitting in living room, working on Internet stuff) (silence)
Frank: (sitting on porch, working on physics stuff) (laughing and laughing)
Me: (still in living room, not working) What? Oo, what’s funny, what?
Frank: (walking in from porch with open book in his hand, full of enthusiasm) It’s a great quote from Wittgenstein!
And if you didn’t know yet that he’s a sweet-natured guy, he agreeably posed for this picture with his great quote in view on top of the new Viking book he bought at the supermarket and is having fun reading.
