Chen Jingrun: Goldbach guessed the first person

　　He was the first generation of mathematicians in New China, known as the "first person to guess Goldbach"; he spent his whole life only to solve an ancient and mysterious mathematical problem; he was once a spiritual idol of the times, changing the direction of the lives of countless young people... He is a generation of mathematical masters Chen Jingrun.

　　Chen Jingrun (1933-1996), a native of Fuzhou, Fujian Province. When he was in middle school, he happened to hear a teacher say that if mathematics is the queen of natural science, then the "Goldbach conjecture" is the jewel in the crown of the queen, and he has been deeply fascinated by the "Goldbach conjecture" ever since.

　　In the summer of 1950, Chen Jingrun was admitted to the Department of Mathematics and Physics of Xiamen University, and after graduation, he went to Beijing No. 4 Middle School to teach. Later, he returned to his alma mater, Xiamen University, as a data administrator in the Department of Mathematics. Working in the mathematical reference room, he was very successful and quickly came up with the results of his research. In 1956, Chen Jingrun published "The Problem inside the Tower", improving the results of Mr. Hua Luogeng in "Stacked Prime Number Theory", and his talent began to be revealed, and he was recognized by the famous mathematician Hua Luogeng and joined the Institute of Mathematics of the Chinese Academy of Sciences.

　　In order to understand the problem of the "Goldbach conjecture", whether it was a hot summer or a harsh winter, in his bucket room of less than 6 square meters, he immersed himself in research, and the calculated straw paper alone was enough to fill a few sacks.

　　After more than 10 years of calculations, in 1966, Chen Jingrun announced in the 17th issue of the Scientific Bulletin that he had proved "1+2" and published a summary of the proof. The significance of this achievement was only clear to a few number theorists in China at that time, but the international mathematical community did not believe it at all, and some even publicly stated in books that this was impossible. In 1972, Chen Jingrun scientifically and completely proved "1 + 2", and in 1973, the second issue of "Science in China" published the full text of his proof, "The large even number table is the sum of one prime number and a product of no more than two prime numbers", which immediately attracted great attention from the mathematical community at home and abroad. Chen Jingrun's paper is recognized as an important milestone in the study of the "Goldbach conjecture", an important number theory method - the "brilliant culmination" of screening theory, and an "outstanding achievement" and "brilliant theorem".

　　In 1980, Chen Jingrun was elected as a member of the Department of Physics and Mathematics of the Chinese Academy of Sciences. He has successively served as a researcher at the Institute of Mathematics of the Chinese Academy of Sciences, a member of the Academic Committee of the Institute, a member of the Mathematical Discipline Group of the State Science and Technology Commission, and the editor-in-chief of the Quarterly Journal of Mathematics. He has published 25 research papers and has written books such as "Fun Talk on Mathematics" and "Combinatorial Mathematics". His achievements in the study of the Goldbach conjecture and other number theory problems are still far ahead of the world, and he is known as the first goldbach conjecture.
