How to Solve It (1945) - George Pólya

This quote ble lagt til av gedeon
There was a seminar for advanced students in Zurich that I was teaching and von Neumann was in the class. I came to a certain theorem, and I said it is not proved and it may be difficult. Von Neumann didn't say anything but after five minutes he raised his hand. When I called on him he went to the blackboard and proceeded to write down the proof. After that I was afraid of Von Neumann.
