Jeden takový je k mání zde :
One day, Einstein, Newton, and Pascal meet up and decide to play a game of hide and seek. Einstein volunteered to be “It.” As Einstein counted, eyes closed, to 100, Pascal ran away and hid, but Newton stood right in front of Einstein and drew a one meter by one meter square on the floor around himself. When Einstein opened his eyes, he immediately saw Newton and said “I found you Newton,” but Newton replied, “No, you found one Newton per square meter. You found Pascal!”.
