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.

《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（Edmund Halley）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。

Having predicted in 1909 that he would "go out" with Halley's comet-which appeared in the year of his birth-he died the day after the comet's closest approach to Earth.

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.

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。
