There is a story about how Albert Einstein was travelling to universities, giving lectures on his famous theory of relativity(相对论). One day while on their way to a university, the driver said, “Dr. Einstein, I've heard that lecture more than 30 times. I have learned it by heart and bet(打赌)I could give it myself.”
“Well, I'll give you the chances，”said Einstein, “they don't know me at the next school. So when we get there, I'll put on your cap and you introduce yourself as me and give the lecture.”
The driver gave Einstein's lecture so wonderfully that he didn't make any mistakes.
When he finished, he started to leave, but one of the professors stopped him and asked him a question which was very difficult. The driver thought fast. “The answer to that question is so simple，”he said, “I'm surprised you have to ask me, in fact, to show you just how simple it is, I'm going to ask my driver to come up here and answer your question.”
