Empty hotel

A biologist, a physicist and a mathematician were sitting in a street cafe watching the crowd. Across the street they saw a man and a woman entering a building. Ten minutes 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.
