That's why

One day our physics professor was discussing a particularly complicated quantum concept. A pre-med student rudely interrupted to ask "Why do we have to learn this stuff?"

"To save lives." the professor responded quickly and continued the lecture.

A few minutes later, the same student spoke up again. "So, how does quantum physics save lives?" he persisted.

"It keeps the ignoramuses out of medical school," replied the professor.

That's good, but there has to be more ways.
