Newton is recognized as a great scientist all over the world. He summed up the achievements of celestial mechanics and ground mechanics, standardized a set of basic concepts for classical mechanics, and put forward three laws of motion and the law of universal gravitation, thus establishing a grand system of classical mechanics. He invented calculus, introduced new mathematical analysis tools into the proof and deduction of mechanics, built the whole mechanics on the basis of strict deduction, and made mechanics a real science. These brilliant achievements are recorded in the Mathematical Principles of Natural Philosophy written by Newton himself.

In Newton's time, there was no distinction between science and philosophy. The word "philosophy" means science and philosophy. The book Principles mainly contributes to natural science, but it also has outstanding opinions in philosophy. It is not only a milestone in the history of science, but also a beacon in scientific research.
