The Mathematical Story of Time
1966, Chen Jingrun, who lives in a 6-square-meter hut, borrowed a dim kerosene lamp, leaned against the bed board and used a pen to consume several sacks of draft paper. 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.

Tong Dizhou studies hard. At the beginning, the school was not allowed to read in the classroom. He looked under the street lamp. The foreigner said that he could not do the experiment. After many experiments, he succeeded and won the praise of the professor.

Hua returned to Tsinghua University as the head of the Department of Mathematics. Soon, he was appointed as the director of the Institute of Mathematics of China Academy of Sciences. He cherishes the great time provided by the party and the state for scientific research. He goes to school with crutches during the day, uses a chopping board as a desk at night, does math research under the lamp, and often writes late into the night. Sometimes, in order to prove a problem, he often gets up late at night, picks up the newspaper at the beginning of the morning, and makes calculations and arguments in the surrounding blanks. In his room, on the desk, on the bed and on the floor, there are piles of calculus papers everywhere. He weaves success and honor with perseverance and diligence.
