About the author:

Isaac newton is one of the most outstanding physicists and mathematicians in17th century, and also the author of Mathematical Principles of Natural Philosophy. He made many contributions in natural science, mathematics and other fields, created a new discipline system, and became one of the classic figures in modern scientific history.

Introduction to books on mathematical principles of natural philosophy;

Mathematical Principles of Natural Philosophy is a work published by Newton in 1687, and it is also one of the most important works in the modern history of science. This book summarizes Newton's scientific research achievements for decades, systematically expounds the concepts of mass, motion and force, and systematically expounds various physical phenomena such as the law of motion and the law of universal gravitation.

The purpose of the mathematical principle of natural philosophy is to explore natural forces from various moving phenomena, and then use these forces to explain natural phenomena. The core contents throughout the book are the three laws of motion and the law of universal gravitation. This book is divided into five parts.

The first part is a long "explanation" written in front of the text, which defines and explains some concepts used in the book, such as force, celestial body, mechanics, motion and the amount of matter.

The second part is "axiom or law of motion", which introduces the three laws of object motion in detail: the law of inertia, the law of the relationship between force and motion, and the law of action and reaction.

The third part is the first volume of this book, which discusses the motion of objects in free space without resistance.

The fourth part is the second volume of the book, which compares the movements of different objects in the blocking medium and obtains the calculation formula that the resistance is proportional to the first and second squares of the object speed. The elasticity and compressibility of gas and the speed of sound in air are also discussed.

The fifth part is the third volume of this book, which deduces the law of universal gravitation on the basis of the argumentation in the first four parts, and illustrates the existence of universal gravitation with a large number of natural facts, including the deviation of moon movement, the change of ocean tides, the length of precession and so on.

Newton's scientific contribution:

Besides the mathematical principles of natural philosophy, Newton made many other important contributions. For example, he founded the theory of calculus and opened up a new field of mathematical research; He put forward the theory of wave-particle duality of light, which promoted the development of optics and became one of the founders of modern optics.

Newton s influence on later generations;

Newton's contribution provided the foundation and enlightenment for later scientific research and application. He initiated the research methods and theoretical system of modern natural science and made great contributions in the fields of physics, mathematics and astronomy. His contribution not only influenced the scientific community at that time, but also had a far-reaching impact on the scientific research and development of later generations.
