A biologist, a physicist, and a mathematician were sitting in a street café watching the crowd. Across the street they saw a man and a woman entering a building. Ten minutes later they reappeared together with a third person. “They have multiplied,” said the biologist. “Oh no, an error in measurement,” the physicist sighed. “If exactly one person enters the building now, it will be empty again,” the mathematician concluded.
WHAT? I don't even get where the people are to begin with. Are they inside and then they leave with 3 people? Do they leave and then walk back past it again? And why does the mathematician say that at the end? Please help !
