Einstein, Newton & Pascal are playing hide and seek Einstein starts counting ""1...2...3..."" and Pascal immediately runs away to hide. Instead of hiding Newton knees down and draws a square of one meter side length. Then he steps inside of it. Einstein finishes counting and turns around. He instantly yells ""Newton I have found you!"" But Newton replies: ""No, what you see is one Newton over one square meter - so what you have found is one Pascal.""
