Chen Jingrun worked the hardest, so he wrote his Goldbach conjecture. When Chen Jingrun was studying in Huaying Middle School in Fuzhou, he was lucky enough to listen to a learned math teacher in Tsinghua University. He told his classmates a world math problem: "About 200 years ago, a German mathematician named Goldbach proposed that' any even number can represent the sum of two prime numbers', or 1+L for short. He never proved it in his life, so he wrote to Euler, a mathematician in St. Petersburg, Russia, and asked him to help prove the problem. After receiving the letter, Euler began to calculate. He tried to prove it to the death. Later, Goldbach passed away with a lifetime of regret, but left this mathematical problem behind. For more than 200 years, Goldbach's conjecture has attracted many mathematicians, making it a big unsolved mystery in mathematics. " The teacher also made an interesting metaphor here. Mathematics is the queen of natural science, and Goldbach conjecture is the jewel in the queen's crown! This fascinating story left a deep impression on Chen Jingrun, and Goldbach's conjecture attracted Chen Jingrun like a magnet. From then on, Chen Jingrun began the arduous process of picking the jewel in the crown ... 1953, Chen Jingrun graduated from the Mathematics Department of Xiamen University and stayed as a librarian. In addition to sorting out books and materials, he is also responsible for correcting homework for students in the mathematics department. Despite the tight time and busy work, he kept on studying math science. Chen Jingrun has a keen interest in mathematical theory. He used all available time to systematically read the mathematical monographs of Hua, a famous mathematician in China. While continuing to learn English, Chen Jingrun learned Russian, German, French, Japanese, Italian and Spanish, so as to read foreign materials directly and master the latest information. Learning these national languages is an amazing breakthrough for a mathematician, but it is only the first step for Chen Jingrun. In order to make his dream come true, whether it is hot or cold in Chen Jingrun, he can't sleep at night in that small room of less than 6 square meters, and concentrate on his studies. Only the calculated toilet paper is fully packed with several sacks. From 65438 to 0957, Chen Jingrun was transferred to the Institute of Chinese Academy of Sciences. As a new starting point, he studied harder. After 10 years of calculation, 1965 in May, he published the paper "Big even number represents the sum of the products of a prime number and no more than two prime numbers". The publication of the paper has been highly valued and praised by the world mathematics community and famous mathematicians. British mathematician Haberstein and German mathematician Li Xite wrote Chen Jingrun's paper into a math book called "Chen Theorem". However, the elites in the field of mathematics in the world don't know the classification of commodities in their daily life, and some commodities are called "idiots" and "weirdos". Xu Chi, two writers, described Chen Jingrun's inner world in Goldbach Conjecture: "I know that my illness is very serious. I'm terminally ill. Bacteria are devouring my internal organs. My mind has reached the point of exhaustion. My body really can't support it! Only my brain cells are extremely active, so I can't stop working. I can't stop. "For Chen Jingrun's contribution, Chinese mathematicians once said: Chen Jingrun challenged the sum of the world's intellectual limits in the field of analytic number theory for 250 years. Deng Xiaoping, the chief architect of China's reform and opening-up, once told people meaningfully: "It would be great to have a thousand scientists like Chen Jingrun in China.". Chen Jingrun's Short Stories: Chen Jingrun was born in a poor family. When his mother gave birth to him, he had no milk and lived by borrowing rice soup from his neighbors. At the age of going to school, my father, who works as a clerk in the post office, earns too little for my eldest brother to go to school, and my mother has to carry her little sister under two years old to work in the fields to earn money. In this way, the burden of looking after the 3-year-old brother on weekdays falls on Xiao Jingrun's shoulder. During the day, he led his little brother to sit on a small bench and count his fingers. When my brother is out of school at night, I beg him to tell him math. When I was older, I squeezed out the gap to help my mother work in the fields and was busy practicing writing and calculus. Seeing that he is eager to learn, his mother sent him to Chengguan Primary School. Although he is thin, he works hard and gets good grades, which makes the children of rich families jealous and kicks him. He couldn't beat those people, so he went home crying and asked to quit school. His mother stroked his wound and said, "Son, we are bullied only because we are poor." You should be eager to learn, fight for breath, grow up and be promising, and then they won't dare to bully us! "Xiao Jingrun dry tears, and went to do homework. Since then, he has never shed tears again, turning physical and mental pain into a driving force for learning, and his grades have been top-notch. Finally, I was admitted to Sanyuan County Junior High School with the first place in the school. In junior high school, he was specially cared for by two teachers: one was a Chinese teacher who was nearly sixty years old and a professor. He witnessed the Japanese bullying, but the Kuomintang was losing ground, and he felt saddened. It's a pity that he is old and places his hopes on the next generation. Seeing that Chen Jingrun is diligent and promising, he often calls him to his side to talk about the 5,000-year history of China's civilization, encouraging him to study hard and shoulder the heavy responsibility of saving the motherland. Teachers often speak with tears in their eyes, and Chen Jingrun also said with tears that he will serve the motherland when he grows up! The other is a math teacher under the age of 30. He graduated from the Department of Mathematics of Tsinghua University with rich knowledge. Chen Jingrun was most interested in math class, a textbook, which was finished in only two weeks. The teacher felt that this student was unusual, so he told him more carefully, further inspiring his patriotic enthusiasm, saying, "If a country and a nation want to be strong, it is absolutely impossible for natural science to be underdeveloped. Mathematics is the foundation of natural science." From then on, Chen Jingrun loved mathematics more. Until I graduated from junior high school, I kept a record of straight A in mathematics. After Chen Jingrun recovered, Chen Jingrun was admitted to Huaying College in Fuzhou to attend high school. Here, he was lucky enough to meet Mr. Shen Yuan, whom he will never forget. Mr. Shen used to be the dean of Tsinghua University Aviation Department and the head teacher of Chen Jingrun. He also taught math and English. Mr. Shen is knowledgeable and persuasive, and all his classmates like to listen to his lectures. Once, Mr. Shen came up with an interesting classical math problem: "Han Xin ordered soldiers". Everyone began to count, Chen Jingrun hurriedly whispered, "53 people. "The whole class was stunned by the speed of his calculation. Teacher Shen looked at the quiet and disheveled student and asked him how he got it. Chen Jingrun blushed and could not speak. Finally, he wrote the method on the blackboard with a pen. Teacher Shen said happily, "Chen Jingrun is fine, but he is afraid to speak. Let me help him! " Aft that lecture, Mr. Shen introduced China's contribution to mathematic in ancient times, saying that Zu Chongzhi's research on pi was earlier than that of Western Europe 1000 year, and Qin in the Southern Song Dynasty solved the simultaneous linear equation more than 500 years earlier than the Italian mathematician Euler. Teacher Shen then encouraged and said, "We can't stop. I hope you can create greater miracles in the future. For example, there is a Goldbach conjecture, which is still an unsolved problem in number theory. People compare it to a jewel in the crown. You should take it off! "After class, Miss Shen asked Chen Jingrun what he thought. Chen Jingrun said quietly, "May I? Teacher Shen said, "Since you can come up with the idea of' Han Xin ordering soldiers' by yourself, you will be able to find the pearl in the future: nothing is difficult to a willing mind! "That night, Chen Jingrun couldn't sleep. He swore that he would work hard at all costs when he grew up, whether he was successful or not!
