Keep laughing (Science jokes-1)

Most of the people think science to be devoid of humor. Consider of any professor of science especially physics or maths. The image at once coming to mind is of a serious person wearing thick spectacles. Most of them are always serious. They laugh rarely as if the subject has sucked their life....Physics never says don't laugh neither mathematics says so. Then why people think of these subjects to be totally lifeless. Being a physics student I don't want to come under this category of serious persons. Rather I would like to come under the category of lively persons just like one of my best friends Geeti...who even being a research scholar in Physics is so lively and having a good sense of humor...There are some more examples also of such people working in these so called lifeless and boring fields....but a few to be counted...So through this post I m just trying to find some humor in these subjects....through some jokes or comic one liners in science...If u have any good jokes related to science then most welcome..

1)An engineer, physicist, and mathematician were sitting together. A fire breaks out.

The engineer start to calculate how much water it takes to put out the fire.

The physicist figures out the best theory on how to put out the fire.

The mathematician tries to prove the fire doesn't exist.
