Newton discovered gravity, established Newtonian mechanics according to Newton's three laws of motion, established the theory of planetary laws, devoted himself to the study of Mitsubishi mirror dispersion and invented reflecting telescope, and discovered the binomial theorem of mathematics and the calculus method.
Introduction to Newton
Sir isaac newton (1643 65438+1October 4th-1727 March 3rd1), chairman of the Royal Society, a famous British physicist, is an encyclopedic "all-rounder" and author of Mathematical Principles of Natural Philosophy and Optics.
He described gravity and three laws of motion in the paper "Laws of Nature" published by 1687. These descriptions laid a scientific view of the physical world for the next three centuries. By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the motion of ground objects and celestial bodies follows the same natural law; It provided strong theoretical support for Heliocentrism and promoted the scientific revolution.
In mechanics, Newton expounded the conservation principle of momentum and angular momentum and put forward Newton's law of motion. In optics, he invented reflecting telescope, and developed the color theory based on the observation that a prism diverges white light into a visible spectrum. He also systematically expressed the law of cooling and studied the speed of sound.
In mathematics, Newton and Gottfried Wilhelm Leibniz shared the honor of developing calculus. He also proved the generalized binomial theorem and put forward Newton's method to approximate the zero point of function, which contributed to the study of power series.
The philosopher's stone
Newton's thirst for knowledge led him to make many scientific discoveries, but these discoveries also led him to take at least one detour: to pursue the legendary philosopher's stone of alchemy. The description of this kind of stone in the book has been handed down from generation to generation, but it is essentially an artificial stone or an alchemy that can realize all kinds of changes. It can turn stone into gold, cure diseases and even turn a stupid cow into a swarm of bees.
Why does alchemy idolize a great scientific picture? You must remember that the steam science revolution only happened in the17th century, and alchemy literature also dabbled in very real chemistry. In any case, the value of this 30-year-old experimental notebook lies in revealing that Newton's vision has far exceeded the expectations of chemical reaction or turning the stone into gold.

Before he imagined how the space cannon and the computational universe could be integrated, Newton used his considerable intelligence on other issues, such as preventing cats from scratching at the door. The story goes like this: Newton's experiment at Cambridge University was interrupted by the cat scratching at the door of the office, so he summoned Newton and found a Cambridge carpenter to saw two holes in his door: one for the cat mother and the other for her child.
Because the kitten just followed her mother through the big hole, the small hole has been useless. The story is still inconclusive. Newton may have invented one of the most popular cat accessories in the world, or just people in Cambridge like to drill holes at will.
