《自然哲学的数学原理》是一本物理学史上首屈一指的鸿篇巨制，一部描述运动规律和万有引力的鸿篇巨著。为此，艾德蒙德·哈雷（EdmundHalley）给予了鼎力资助，次年这一巨著终于呈现在世人面前。艾德蒙德·哈雷本人因发现哈雷彗星而名垂青史。

That the most important volume in the history of physics , which described the laws of motion and of gravity , saw the light of day the next year was , in the end , due to the deep pockets of Edmund Halley , of comet fame .

英国天文学家J.R.海德曾经使用这些数据计算哈雷彗星的运行轨道，他发现，彗星运行轨道角度呈变小趋势：在汉代，角度为1700，到19世纪中叶，则减至1610。

R. Hind , a British astronomer , once usedthese continuous data to calculate the orbit of Halley 's Comet , and discovered that the angle of the orbit showed a narrowing trend.In the Han Dynasty , it was 170 degrees , but it nar-rowed down t0 161 degrees in the mid-9th century .
