众所周知，牛顿的伟大灵感来自于他进过一颗树的时候掉落的苹果。这个苹果改变，并且促进了社会文明。很多人开玩笑说，如果苹果打在他们的头上，也许他们也能成为下一个牛顿。

It is known to all that Newton got the great inspiration from the falling apple as he was walking pass a tree. This apple changed and promoted the social civilization. Many people play the joke that if the apple hits on their heads, maybe they can be the next Newton. Actually, apple is just the stimulation to help Newton to figure out his thoughts. If it hits on other people's heads, it is just the ordinary incident and nothing special. The meaning of life is to keep searching. Everyone can make a difference if they keep thinking, and inspiration will come sooner or later. At that time, the success will be at hand. 
众所周知，牛顿的伟大灵感来自于他进过一颗树的时候掉落的苹果。这个苹果改变，并且促进了社会文明。很多人开玩笑说，如果苹果打在他们的头上，也许他们也能成为下一个牛顿。实际上，苹果只是一种刺激，帮助牛顿理清楚他的想法，如果撞到别人的头上，只是普通的一件事而已，没什么特别的。生命的意义在于不停的探索，每个人都可以有所作为。如果他们不断思考，灵感迟早会来的。在那个时候，成功也就不远了。
