Von Neumann and Nobert Weiner were both the subject of many dotty
professor stories. Von Neumann supposedly had the habit of simply
writing answers to homework assignments on the board (the method
of solution being, of course, obvious) when he was asked how to solve
problems. One time one of his students tried to get more helpful
information by asking if there was another way to solve the problem.
Von Neumann looked blank for a moment, thought, and then answered,
“Yes.”.
Weiner was in fact very absent minded. The following story is told
about him: When they moved from Cambridge to Newton his wife, knowing
that he would be absolutely useless on the move, packed him off to
MIT while she directed the move. Since she was certain that he would
forget that they had moved and where they had moved to, she wrote down
the new address on a piece of paper, and gave it to him. Naturally,
in the course of the day, an insight occurred to him. He reached in
his pocket, found a piece of paper on which he furiously scribbled
some notes, thought it over, decided there was a fallacy in his idea,
and threw the piece of paper away. At the end of the day he went
home (to the old address in Cambridge, of course). When he got there
he realized that they had moved, that he had no idea where they had
moved to, and that the piece of paper with the address was long gone.
Fortunately inspiration struck. There was a young girl on the street
and he conceived the idea of asking her where he had moved to, saying,
“Excuse me, perhaps you know me. I’m Norbert Weiner and we’ve just
moved. Would you know where we’ve moved to?” To which the young
girl replied, “Yes daddy, mommy thought you would forget.”
The capper to the story is that I asked his daughter (the girl in
the story) about the truth of the story, many years later. She
said that it wasn’t quite true — that he never forgot who his
children were! The rest of it, however, was pretty close to what
actually happened…
