A physicist, a mathematician and a programmer are in a car driving on a windy mountain path. All of a sudden as they round a corner, the brakes fail. After a few terrifying moments, the car skids to a halt and they emerged unscathed. The physicist thinks for a second, and says "It must be the lower pressure due to the air, it's made some of our brake fluid evaporate, we should get some more brake fluid before we get back in the car." The mathematician says "No if we calculate the rate of a evaporation we'd never lose that much. It must be a leak in the lines. We should fix the leak before we get back in" The programmer says "Let's get back in the car and see if it's reproducible."
