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."
