Once, Einstein gave a lecture in a university. After his speech, the audience started asking questions.
A girl asked, "Do you think you're a giant of science?" Einstein said with a smile, "A giant is a person who is tall in height. You see I'm so small, how can I be a giant? Maybe I see a bit farther, only because I stand higher!"Then a boy asked, "You mentioned you stand higher than the others. It reminds me that you had a talk with a lady on the top of the Alps (阿尔卑斯山).I don't want to ask what you talked, but I want to know whether you realised you have been a top in the history of science when you stood on the top." Looking at the boy carefully, Einstein replied, "Well, my height cannot become a top. And there is no top that no one can get to, so we don't want to be a top, but we want to be a person to climb the top!"
Then he took up a piece of chalk and wrote on the blackboard, "Standing on the top, you are not tall, but even smaller!"Then he said, "Though I stand tall, in the eyes of the world I'm still small! Finally, I can tell you a sentence, which was the last one I told the lady on the top of the Alps, 'Any top can be reached, for there is no giant in the world but the one who stands higher!'"A storm of applause(掌声) sounded. The lady who listened to Einstein's instruction on the Alps that year was no other than Madam Curie!
