据说,牛顿发现万有引力定律,是因为一个苹果正好落在了他的头上。那天,牛顿正在树下休息,这时,一个苹果从枝头上落下来,正好砸在牛顿的头上,牛顿摸了摸被苹果砸疼的头,然后捡起滚落在地上的苹果,开始思考起来:为什么苹果是向下掉,而不是向上掉呢?或者为什么不是向侧面掉呢?经过一连串的思考,从而牛顿发现了一个伟大的定律,也就是万有引力定律。那时,我在想,牛顿真幸运,上帝把一个苹果“砸”在了他的头上,让一个机会的苹果亲吻了他的额头。
It is said that Newton found the law of gravity, because an apple just fell on his head. That day, Newton was resting under the tree, when an apple fell from the branch and hit Newton’s head. Newton touched the head smashed by the apple and picked up the apple that fell on the ground and started Think of it: why the apple is falling down rather than upwards, or why not falling laterally? After a series of reflections, Newton discovers a great law, that is, the law of universal gravitation. At that time, I was thinking that Newton was lucky that God put an apple on his head and let a chance apple kiss his forehead.
