Isaac newton (1643 65438+1October 4th-1727 March 3rd1), Sir, President of the Royal Society, a famous British physicist and mathematician, is an encyclopedic "all-rounder" who has written the mathematical principles of natural philosophy and optics.

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 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.

Newton's mathematical achievements:

Most modern historians believe that Newton and Leibniz independently developed calculus and created their own unique symbols for it. According to people around Newton, Newton came up with his method several years earlier than Leibniz, but he hardly published anything before 1693, and didn't give his complete explanation until 1704.

At the same time, Leibniz published a complete description of his method in 1684. In addition, Leibniz's symbol and "differential method" were completely adopted in continental Europe, and this method was also adopted in Britain about 1820 years later. Leibniz's notebook records the development process of his thoughts from the early stage to the mature stage, but only Newton's final result is found in the known records.

Newton claimed that he had been reluctant to publish his calculus because he was afraid of being laughed at. Newton was closely related to the Swiss mathematician Nicolas Fadio Diu Lei, who was attracted by Newton's law of universal gravitation from the beginning. 169 1 year, Diu Lei intended to compile a new edition of Newton's mathematical principles of natural philosophy, but he never finished it.
