An engineer, a physicist and a mathematician are sleeping in a hotel.

In the middle of the night a power surge happens and all three of their room kettles catch fire.

The engineer quickly locates the fire extinguisher and puts out the fire.

The physicist remembers from his college years that combustion feeds on oxygen, so he runs to the bathroom and covers the kettle with towels, putting out the fire.

The mathematician wakes up, sees the fire extinguisher in the corner and promptly goes back to sleep: he just proved that a solution exists.
