All the greatest scientific minds of the ages were hanging out in heaven. They decided to play hide and seek. Einstein agreed to seek first, so he covered his eyes and started counting to a hundred.
“One… two… three…”
All the scientists ran off to find hiding places, except Newton. Instead, he drew a big square and stood right in the middle of it. When Einstein reached 100, Newton was standing right in front of him.
“Newton is out!” he shouted to the other scientists.
“No, that’s not true,” said Newton. “I’m not Newton.”
By this time the other scientists had come out of their hiding places, and they informed him that he most certainly was Newton, and so it was his turn to seek.
“But the area of this square is exactly one meter,” he tells them. “At one Newton per square meter, I am actually Pascal. So Pascal is out!”
Pascal closed his eyes and started counting to a hundred.
