Gauss is a great German mathematician. When he was a child, he was a clever boy and loved to think.
When I was in primary school, once a teacher tried to cure naughty students in his class. He worked out a math problem and asked the students to increase ... from 1+2+3 to 100. He thinks this question is enough for these students to calculate for half a day, and he may also get half a day's leisure. Who knows, to his surprise, only after a while. Little gauss raised his hand and said that he was finished. The teacher looked at the answer, 5050, exactly right. The teacher was surprised. Ask little Gauss how to work it out. Gauss said that he didn't add it from beginning to end, but first added 1 and 100 to get1kloc-0/,then added 2 and 99 to get1kloc-0/,and finally added 50 and 5 1. The clever Gauss was praised by the teacher.
Look at the story of Chen Jingrun.
Chen Jingrun is one of the world famous analytic number theorists. In the 1950s, he made important improvements on the existing results of Gauss circle lattice point problem, sphere lattice point problem, Tali problem and Waring problem.
After 1960s, he made extensive and in-depth research on screening methods and related important issues. 1966, Chen Jingrun, who lives in a six-square-meter cabin, borrowed a dim kerosene lamp, leaned against the bed board and consumed several sacks of draft paper with a pen. He actually conquered (1+2) in the world-famous mathematical puzzle "Goldbach conjecture", creating a distance from taking off the crown jewel of number theory (1+66). He proved that "every big even number is the sum of the products of a prime number and no more than two prime numbers", which made him a world leader in Goldbach's conjecture research. This result is called "Chen Theorem" internationally and is widely quoted. This work also enabled him, Wang Yuan and Pan Chengdong to win the first prize of China Natural Science Award with 1978 * *. His achievements in studying Goldbach conjecture and other number theory problems are still far ahead in the world. A world-class master of mathematics and American scholar A Will (A? Weil) once praised him like this: "Every job in Chen Jingrun is like walking on the top of the Himalayas."
