牛顿与苹果的故事

Newton and the apple

传说1665年秋季，牛顿坐在自家院中的苹果树下苦思着行星绕日运动的原因。这时，一只苹果恰巧落下来，它落在牛顿的脚边。这是一个发现的瞬间，这次苹果 下落与以往无数次苹果下落不同，因为它引起了牛顿的注意。牛顿从苹果落地这一理所当然的现象中找到了苹果下落的原因——引力的作用，这种来自地球的无形的 力拉着苹果下落，正像地球拉着月球，使月球围绕地球运动一样。

As legend has it, in the autumn of 1665, Newton was sitting under the apple tree in his yard thinking hard about the reason why the planets rotate around the sun. At that moment, an apple coincidentally fell by his foot. It was a moment of discovery. This time when the apple fell, it was different from any other time because it had caught Newton's notice. From a phenomenon that everyone had taken for granted, Newton found the reason why the apple fell – it was gravitation! This invisible force from the earth pulled the apple just like it pulled the moon, making the latter rotate around the earth.
