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
