He calculated the surface area and volume, parabola and ellipse area of a sphere by approximation method. It was on the basis of Archimedes' research that later scientists developed modern calculus. He calculated pi by secant circle, which should be between 3.141~ 3.142.
Newton, who unveiled the veil of God, not only put forward three principles of mechanics, but also made outstanding achievements in mathematics. Calculus, the lowest speed line, binomial formula, all of which were made by Newton, sound better than other mathematicians of his time. Newton's greatest skill in mathematics was to study physics with calculus.
Euler, the great god of mathematics, finished Newton's professional masterpiece on the mathematical principles of nature at the age of 9. 19 years old received a doctorate. When Euler was 20 years old, Noble, a famous Russian mathematician, invited him to Russia as the dean of the Institute of Physiology. At the age of 28, it took Euler three days to find a way to calculate the orbit of a comet. But God is jealous of talents. This year, God blinded his right eye. But the disease did not hinder Euler's life. At the age of 29, he put forward the concept of particle in his monograph and introduced vector into kinematics. At the age of 32, Euler initiated two new disciplines: fluid dynamics and aerodynamics.
Gauss, the great god of mathematics, began to doubt the basic proof in element geometry when he was 12 years old. At the age of 16, he asserted that a non-Euclidean geometry would be produced. Best of all, it took Gauss only one night in college to solve this mathematical problem that has puzzled mathematicians for more than 2,000 years. This topic is the drawing theory and method of positive 17 square ruler. Newton didn't do it, but he did.
