只要一提到行星的运动,人们便会立刻联想到万有引力,这是牛顿的一大功绩。可是有些人却不知道这其中还包含有另一些科学家出色的工作和辛勤的劳动,特别值得一提的是德国人开普勒,他以毕生的精力,从浩翰的天文观测资料中总结出著名的“行星运动三定律”,直接导致万有引力定律的发现。在这一段科学发展史中,既有 Whenever one mentions the movement of the planet, people immediately associate it with gravitation, which is a great achievement for Newton. However, some people do not know that it contains excellent work and hard work by other scientists. Particularly worthy of mention is the German Kepler, who, with his lifelong energies, concludes with Hao Han’s astronomical observations The famous “three laws of planetary motion,” a direct result of the discovery of the law of universal gravitation. In this section of the history of scientific development, both
