A mathematician, an engineer, and a computer scientist were travelling together.
They were enjoying a drive in the countryside, when suddenly the engine spluttered and stopped.
The mathematician said, We came past a gas station a few minutes ago. One of us could go back and ask for help.”
The engineer said, “I could have a look at the engine. I might be able to fix it.
The computer scientist thought for a moment then said, “Why don’t we just open the doors, slam them shut, and see if everything works again?”
