1, Newtonian mechanics is based on Newton's three laws of motion.
2. Discover the law of universal gravitation.
3. Establish the theoretical basis of planetary laws.
4. Committed to the study of Mitsubishi mirror dispersion, invented the reflective telescope.
5. Discover the binomial theorem of mathematics and the calculus method.
In Newton's time, Copernicus put forward Heliocentrism, Kepler summarized three empirical laws of planetary motion from Tycho's observation data, Galileo gave the concepts of force and acceleration and discovered the laws of inertia and free fall. It was at this time that Newton made a comprehensive survey of the movements of planets and objects on the ground. He used mathematical methods to make physics a complete system, which can express causality. This is what we call the classical mechanical system today.

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 the scientific view of the physical world in the next three centuries and became the basis of modern engineering. By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the movements of ground objects and celestial bodies all follow the same natural law; It provides strong theoretical support for the sun-centered theory and promotes the scientific revolution.
In mechanics, Newton expounded the conservation principle of momentum and angular momentum and put forward Newton's law of motion? [ 1]。 In optics, he invented reflecting telescope, and based on the observation that a prism diverges white light into the visible spectrum, he developed the color theory. 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.
In economics, Newton put forward the gold standard.
