A group of scientists gathered in front of a house believed to be empty. They watched as one person entered the house. A while later they were surprised to see two persons leaving the house. First the biologist exclaimed

They must have multiplied!

No, said the physicist, this is just a measurement error

Wait, said the economist, what you observe is a typical case of capitalization

But the mathematician was silent, thinking hard, like mathematicians do (in jokes), before he finally said: If a person enters the house now, it will again be empty



I heard this joke from Per Manne
