Why Learn Physics

A college physics professor was explaining a particularly complicated concept to his class when a pre-med student interrupted him.

- Why do we have to learn this stuff? - the frustrated student blurted out.

- To save lives - the professor responded before continuing the lecture.

A few minutes later the student spoke up again:

- So how does physics save lives?

The professor stared at the student without saying a word.

- Physics saves lives - he finally continued, because it keeps the idiots out of medical school.
