At a pre-med university in St. Louis, we had to take a difficult class in physics. One day the professor was discussing a particularly complicated concept. A 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 physics save lives? he persisted. It usually keeps the idiots like you out of medical school, replied the professor.

在圣路易斯的一所醫(yī)學(xué)院預(yù)科大學(xué)，學(xué)生必須修一門很難的物理課。一天，教授正在探討一個(gè)特別復(fù)雜的概念，一個(gè)學(xué)生粗魯?shù)卮驍嗨脑?，?wèn)道：為什么我們一定要學(xué)這種東西？

為了救人。教授很快回答，繼續(xù)講課。幾分鐘后，那個(gè)學(xué)生再次大聲堅(jiān)持：那么物理怎么救人呢？教授回答：它通?？梢园涯氵@種笨蛋趕出醫(yī)學(xué)院。
