The Principia deals primarily with massive bodies in motion, initially under
a variety of conditions and hypothetical laws of force in both non-resisting
and resisting media, thus offering criteria to decide, by observations, which
laws of force are operating in phenomena that may be observed. It attempts to
cover hypothetical or possible motions both of celestial bodies and of
terrestrial projectiles. It explores difficult problems of motions perturbed
by multiple attractive forces. Its third and final book deals with the
interpretation of observations about the movements of planets and their
satellites.
为什么有字数限制?为什么只容许这么少的字?
为什么标题连Philosophiæ Naturalis Principia Mathematic都没办法显示完全?
站长给我出来解释喔!
为什么标题要限制在这么少的字数?
长标题错了吗?长就不行?长的也蛮好的不是吗?
现在要我怎么跟人解释要谈Philosophiæ Naturalis Principia Mathematic而不是
Philosophiæ Naturalis Principia Mathe?
说到底Mathe是什么?
为什么发生这种事?
谁能负责?谁要负责?
