Anedota...

One day at the weekly colloquium in the Harvard Psychology Department (with which the Psycho-Acoustic Laboratory was affiliated), the guest speaker was at his worst and gave an extraordinarily long and dull lecture on a mathematical theory of behavior. Unfortunately, the audience responded in kind, and at equally great length, with pointless questions and irrelevant comments. When at long last it was all over, von Békésy led me directly to the blackboard in his office, picked up a piece of chalk, and said "This is the most important but least known equation in all of the social sciences. Always remember it, for as you have just seen, it completely describes a great deal of human behavior."

And then — summing up the whole afternoon neatly - he wrote:

0 + 0 = 0
