1. Chen Jingrun (1933—1996)1933, born in Minhou, Fujian, on May 22nd. Born in poverty, he studied hard and had a soft spot for mathematics when he was in primary and secondary schools. He did exercises whenever he had time and became a "little math fan" at school. He is inarticulate, sincere and kind, never cares about personal gains and losses, and has devoted his life experience to the cause of mathematics. Without graduating from high school, he was admitted to Xiamen University with the same academic qualifications. 1953 graduated from the Mathematics Department of Xiamen University. From 65438 to 0957, he entered the Institute of Mathematics of China Academy of Sciences and studied number theory under the guidance of Professor Hua. He has been a researcher at the Institute of Mathematics of China Academy of Sciences, a member of the academic committee, a professor at Guiyang University for Nationalities, Henan University, Qingdao University, Huazhong University of Science and Technology and Fujian Normal University, a member of the Mathematics Discipline Group of the State Science and Technology Commission, and the editor-in-chief of Mathematics Quarterly. Mainly engaged in the research of analytic number theory, and achieved international leading results in the research of Goldbach conjecture. This achievement is called "Chen Theorem" internationally and is widely cited.

Second, johann bernoulli's son daniel bernoulli went to Russia on 1725 and recommended Euler to czar Cadling I, so Euler came to Petersburg on 1727. 1733, at the age of 26, Euler became a professor of mathematics at the Academy of Sciences in Petersburg. 1735, Euler solved an astronomical problem (calculating the orbit of a comet), which took several famous mathematicians several months to solve, but Euler used his own invented method and completed it in three days. However, overwork made him suffer from eye diseases and unfortunately lost his right eye. At this time, he was only 28 years old. 174 1 year, at the invitation of Peter the Great of Prussia, Euler went to Berlin as the director of the Institute of Physics and Mathematics of the Chinese Academy of Sciences until 1766, and later returned to Petersburg at the sincere invitation of Tsar Cadling II. Unexpectedly, not long after, his left eye vision decreased and he was completely blind. Unfortunate things followed. 177 1 year, the Petersburg fire damaged Euler's residence. 64-year-old Euler was blinded by illness and was trapped in the fire. Although he was saved from the fire by others, his research and a lot of research results were reduced to ashes.

The heavy blow still didn't make Euler fall, and he vowed to get the loss back. Before he was completely blind, he could still see vaguely. He seized the last moment, scribbled the formula he found on a big blackboard, and then dictated its contents, which were recorded by his students, especially his eldest son A Euler (mathematician and physicist). After Euler was completely blind, he still fought against the darkness with amazing perseverance and studied with memory and mental arithmetic until his death, which lasted 17 years.

I hope my answer is helpful to you! ! ! ! !
