Einstein, Newton, and Pascal are playing the game of hide-and-go-seek. It's Einstein's turn to be IT, hide his eyes and count to ten. Pascal runs off and hides. Newton draws a one meter by one meter square on the ground in front of Einstein and then stands in the middle of it.
Einstein reaches the number ten and uncovers his eyes. He sees Newton immediately and exclaims: "Newton, I found you. You're it!"
Newton smiles and says: "You didn't find me, you found a Newton over a square meter. That is, you found Pascal."
