Zeta function (Cambridge Computing)

Summer 1937, Cambridge England. Wittgenstein and Turing have made plans to to go see a flick (Secret Agent).

Turing arrives in the hallway outside Wittgenstein's rooms just as the door opens and a flock of philosophy students depart from their session with Wittgenstein. Turing stands aside and listens to the very load voice of Wittgenstein from inside, "You cannot doubt just this and that. It is the number of things that you cannot doubt that you can count on one hand."

The voice of the student is hard to hear, something like, "Well, I doubt that."

Wittgenstein laughs and looks out the door, sees Turing. "Here's Turing! He's a mathematician, he believes an infinite number of things....he cannot even write a proof that does not include infinity."

Turing nods to the student and does an little dance as they both try to go through the door at the same time. Wittgenstein is striding around the room pushing furniture around standing folding chairs in corners. Turing knows from experience that Wittgenstein will be in no mood to talk until he quiets the bubbling thoughts that arose during the session with the students. Finally, all the furniture has been pushed multiple times and Turing realizes that Wittgenstein s looking for something. Turing picks up a piece of paper from beside Wittgenstein's writing table. On it is a sketch.



Wittgenstein notices what Turing is holding and he says, "What is the most wonderful thing for a mathematician?"

Turing replies, "Finding a simple solution to a problem that has been thought to be difficult."

"And how can anything first appear difficult and then be found to be easy?"

"You just find the right way to look at."
