1642 16 On February 25th, isaac newton was born in a farmer's family in Walsop, Lincolnshire, England. Newton was a premature baby, weighing only three pounds at birth. The midwife and his relatives are worried about whether he will survive. No one expected that this seemingly insignificant little thing would become a giant of science and live to be 85 years old.

Newton's academic performance before he went to middle school was not outstanding. He just liked reading, but he was curious about natural phenomena and liked to creatively do gadgets, tricks, inventions and experiments.

166 1 year, Newton was admitted to Cambridge University. Here, his talents have been fully brought into play. As a scientist in modern science and the founder of mechanics, Newton has made great achievements in many scientific fields. The publication of his book Mathematical Principles of Natural Philosophy marks the beginning of the era of human science.

Newton's major achievements

Newton described gravity and three laws of motion in the paper "Laws of Nature" published in 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. 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 cooling law 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.
