Einstein, Newton, and Pascal are hanging out one afternoon. Einstein is bored, so he suggests, “Let’s play hide-and-seek! I’ll be it!”
The others agree, so Einstein begins counting. Pascal runs off right away to find a place to hide. But Newton merely takes out a piece of chalk and draws a square around him.
When Einstein opens his eyes, he immediately spots Newton standing in front of him. He says, “I found you, Newton!”
Newton replies, “No, you found one Newton per square meter- you found Pascal!”
