What are the major achievements of Chen Jingrun?
1933 was born in Fuzhou, Fujian on May 22nd.

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.

1965 claimed that he had proved it (1+2), which was reviewed by senior brother Wang Yuan and published in Science Bulletin in June 1966.

1974 Premier Zhou, who was seriously ill, personally recommended him as a representative of the Fourth National People's Congress and was elected as a member of the National People's Congress Standing Committee (NPCSC).

1979 completed the paper "Minimum Prime Number in arithmetic progression", and extended the minimum prime number from 80 to 16, which was well received by the international mathematics community. [2]

1979 was invited by Princeton Institute of Advanced Studies to give lectures and visit, which attracted extensive attention from foreign counterparts.

198 1 was elected as an academician of China Academy of Sciences.

1On April 27th, 984, when he was crossing the road, he was knocked down by a galloping bicycle and landed on the back of his head, which induced Parkinson's disease.

1March 1996 19 was hospitalized due to illness and died at the age of 62 after being rescued.

Son: Chen Youwei (born in February 198 1)

This is a miracle that shocked the whole world: a mathematician who lives in a 6-square-meter hut borrowed a dim kerosene lamp, leaned against the bed board and consumed several sacks of draft paper with a pen, thus overcoming "1+2" in the world-famous mathematical puzzle "Goldbach conjecture" and creating a distance of "1+60".

Chen Jingrun, a famous mathematician in China, created this miracle.

Chen Jingrun 1933 was born in Fuzhou, Fujian on May 22nd. He was a thin and introverted child since childhood, but he fell in love with mathematics. Computational math problems occupy most of his time, and boring algebraic equations make him full of happiness. From 65438 to 0953, Chen Jingrun graduated from the Mathematics Department of Xiamen University. Because of his excellent research on a series of problems in number theory, Hua was attached importance and transferred to the Institute of Mathematics of China Academy of Sciences.

In 1950s, Chen Jingrun made important improvements on the existing results of the problems of inner lattice points in Gauss circle, inner lattice points in sphere, Tali problem and Waring problem. After 1960s, he made extensive and in-depth research on screening methods and related important issues.

Goldbach conjectures that this world-class mathematical problem that has been unresolved for more than 200 years has attracted the attention of thousands of mathematicians all over the world, but few people can really challenge this problem. In high school, Chen Jingrun listened to his teacher's philosophical remarks: the queen of natural science is mathematics, the crown of mathematics is number theory, and Goldbach conjecture is the jewel in the crown. This crucial enlightenment became his unswerving goal all his life.

Chen Jingrun studies mathematics day and night.

In order to prove Goldbach's conjecture and win the world-famous pearl of mathematics, Chen Jingrun trudged in the field of mathematics with amazing perseverance. Hard sweat has brought fruitful results. 1973, Chen Jingrun finally found a simple method to prove Goldbach's conjecture. After his achievement was published, it immediately caused a sensation in the world. Among them, "1+2" was named "Chen Theorem", also known as the "glorious vertex" of the screening method. Hua and other mathematicians of the older generation spoke highly of Chen Jingrun's paper. Mathematicians from all over the world have also published articles praising Chen Jingrun's research achievement as "the best achievement in studying Goldbach's conjecture in the world at present".

Chen Jingrun's research on Goldbach's conjecture is still far ahead in the world. A world-class master of mathematics and an American scholar once praised him like this: "Every job in Chen Jingrun seems to be walking on the top of the Himalayas." 1978 and 1982, Chen Jingrun was twice invited by the international congress of mathematicians to give a 45-minute lecture. [3]

In addition, Chen Jingrun also conducted in-depth research and discussion on the relationship between combinatorial mathematics and modern economic management, cutting-edge science and technology and human beings. He has published more than 70 scientific papers in newspapers and periodicals at home and abroad, including "Interesting Talks on Mathematics" and "Combinatorial Mathematics". He has won the first prize of National Natural Science, Heli Fund Award, China Mathematics Award and many other awards.

Chen Jingrun enjoys a high reputation at home and abroad, but he is not complacent. He said: "I just climbed a hill on the road of science. I haven't reached the real peak yet, so I will continue to work hard. "

1March 1996 19 years, after suffering from Parkinson's syndrome 10 years, Chen Jingrun died of respiratory and circulatory failure at the age of 63.

Marriage story

The publication of Xu Chi's "Goldbach Conjecture" was as shocking as a whirlwind, shocking the Chinese and foreign mathematical circles. Comments at home and abroad say: "Chen Jingrun has become a major landscape in China's scientific spring". He was invited to attend the National Science Conference, and Comrade Deng Xiaoping cordially received him. Chen Jingrun was in poor health at that time, and Comrade Xiaoping took good care of him. After the meeting, Chen Jingrun was sent to Gao Qian Ward of 309 Hospital of the People's Liberation Army. His arrival caused a sensation throughout the hospital. The hospital leaders gave a warm reception, and all doctors and nurses respected this world-class mathematician. 1977 1 1 You Kun, who was sent from Wuhan Military Region to 309 Hospital for further study, was dragged by his companions to see China, a famous figure. This is really fate. In the past, people in Chen Jingrun didn't even mention women's names and didn't even say a word. Chen Jingrun, who is nearly half a century old, saw Youkun this time. His eyes lit up and he warmly greeted Youkun and invited them to come in and sit down. Later, Kun was sent to the ward in Chen Jingrun as a doctor on duty. There are more opportunities for such contact. Every time Kun Yi appears, Chen Jingrun is particularly happy. One day, Chen Jingrun asked Youkun with concern, where does he live? Do you have a boyfriend or family? Yu Kun was unprepared and said bluntly, "No, no, it's still early." Later, Yu Kun also paid close attention to the China mathematician, and they fell in love. They got married with the help of the organization. Since then, Chen Jingrun, a mathematician known as "idiot" and "eccentric", has a warm home.

Mrs Chen Jingrun is touching Yu Kun's statue of Chen.

Chen Jingrun is not only a genius in mathematics, but also has unique ideas in educating children. The son's name is Chen Youwei. The name "Chen Youwei" was coined by Chen Jingrun. It is his and his wife's respective surnames, and Wei hopes it can make great contributions to mankind. Chen Jingrun's method of cultivating his only son is to treat his son democratically. Family democracy, father-son democracy, mother-child democracy, let the child grow up freely and make his way of thinking more individual. Chen Jingrun believes that children can only be successful if they have personality, and artists, politicians and scientists all succeed by the development of personality. Chen Jingrun hopes that his son will become a scientist in the future. Chen Youwei is born smart. Whenever he picks up a toy, he dissects it curiously-take it apart to see it clearly. A toy costs tens of dollars, and a mother will pull her face down and seriously criticize her son. At this time, Chen Jingrun always stood beside his son cheerfully and said, "Curiosity is a good thing for children. His ability to take apart toys proves that he is curious and can study problems. Parents should support him. " After my son went to primary school, he often talked with Chen Jingrun about his own affairs, study, work or communication with his classmates. Chen Jingrun listened carefully, and then praised or criticized and corrected the children. Soon, he gained the trust of his children and became friends with his son. Chen Jingrun believes that the education and cultivation of children should vary from person to person, and the ways and means of education should be different under different environments and personalities. This is what makes this world-famous mathematician different. Chen Jingrun and Yu Kun said happily that educating children should be flexible and phased. Children's growth is inseparable from educational methods. [4]

Anecdotes of life

Chen Jingrun doesn't like walking in the park or walking in the street, but he likes studying. When I study, I often forget to eat and sleep.

One day, Chen Jingrun touched his head during lunch. Alas, his hair is too long. He should get a haircut at once, or others will think he is a girl. So he left work and ran to the barber shop.

There are so many people in the barber shop that everyone cuts their hair next to each other. Chen Jingrun's brand is the small brand number 38. He thought it was too early for me to turn now. Time is so precious that I can't waste it. He hurried out of the barber shop, found a quiet place to sit down, then took out a small notebook from his pocket and recited new words in a foreign language. He recited it for a while and suddenly remembered that when he was reading a foreign language in the morning, there was one place he didn't understand. You must understand what you don't understand. This is Chen Jingrun's temper. He looked at his watch. It's only half past twelve. He thought: check in the library first, and then come back for a haircut. He stood up and left. Who knows, not long after he left, it was his turn to get a haircut. The barber's uncle shouted, "Number 38! Who is number thirty-eight? Come and get a haircut! " Think about it. Chen Jingrun is reading in the library. Can he hear the barber's uncle calling number 38?

After a long time, Chen Jingrun found something he didn't understand in the library, and then went to the barber shop happily. But he passed by the foreign language reading room, and there were all kinds of new books, which were really nice. He ran in and read another book. It was not until the sun went down that he remembered to cut his hair. As soon as he touched his pocket, the little sign No.38 was still lying well. But what's the use of his coming to the barber shop? This number is outdated.

As soon as Chen Jingrun entered the library, it was like falling into a honey pot, and he couldn't bear to leave. Yes, another day, Chen Jingrun had breakfast, took two steamed buns and a pickle, and went to the library.

Chen Jingrun found the quietest place in the library and read carefully. He stayed until noon and felt a little hungry, so he took out a steamed bun from his pocket and was still reading while eating.

"Ding Lingling ..." The bell rang, and the librarian shouted, "It's time to get off work, please leave the library!" The somebody else all gone, but Chen Jingrun didn't hear, or 1 vigorously in reading.

The librarian thought that everyone had left the library, so he locked the library door and went home.

Time passed quietly and it was getting dark. Chen Jingrun looked out of the window and said to himself, What a strange weather it is today! It's sunny for a while and cloudy for a while. He pulled down the switch wire of the light and sat down to read. Watching, he suddenly stood up. It turned out that he read a book all day and began to understand. Now, he will go back to the dormitory and continue to do the problems he left unfinished yesterday.

Chen Jingrun put the book away and went out. The library is quiet and there is no sound. Hey, where's the janitor? Why doesn't anyone come to read? Chen Jingrun looked at his watch. Ah, it's past eight o'clock in the evening. He pushed open the locked door; He shouted at the door: "Please open the door! Please open the door! " But no one answered.

In normal times, Chen Jingrun will go back to his seat and continue reading until the next morning. But, not today! He's going back to the dormitory to do that unfinished problem!

He went to the telephone and called the office. But there was no answer, only a beep. He dialed this number several times, but no one answered. What shall we do? At this moment, he remembered the secretary of the Party Committee and dialed the telephone immediately.

Chen Jingrun? The party secretary was surprised when he received the phone call. He was overjoyed, looked into it and said with a smile, "Chen Jingrun! Chen Jingrun! You have worked hard, you are really a good comrade. "

The party secretary immediately sent some comrades to the librarian. The door of the library opened and Chen Jingrun said to the librarian, "I'm sorry! I'm sorry! Thank you, thank you! " As he spoke, he ran down the stairs and returned to his dormitory.

He turned on the light and set about solving the problem at once.

Chen Jingrun and Goldbach conjecture

one

When Chen Jingrun was studying in Huaying Middle School in Fuzhou, she was lucky enough to listen to the math teacher Shen Yuan transferred from Tsinghua University. He told his classmates a world math problem: "About 200 years ago, a German mathematician named Goldbach proposed that' any even number greater than 2 can represent the sum of two prime numbers', abbreviated as 1+ 1. 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 course of winning the crown jewel of mathematics. ......

1953, Chen Jingrun graduated from the Department of Mathematics of Xiamen University, and once stayed there. He works as a librarian in the library. 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 insisted 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 foreign 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 can't be named, so they are called "idiots" and "weirdos".

Writer Xu Chi described Chen Jingrun's inner world in Goldbach Conjecture: "I know 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 said meaningfully to people: "How wonderful it is 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, so he 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.

Jingrun Chen

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 spoke a few extra words to further stimulate his patriotic enthusiasm, saying, "If a country or a nation wants 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 the recovery of the motherland, Chen Jingrun was admitted to Huaying Public School 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, and Chen Jingrun quickly 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. I'll 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, Teacher Shen asked Chen Jingrun what he thought. Chen Jingrun said quietly, "May I?" Teacher Shen said: "Since you can figure out' Han Xin points soldiers' by yourself, you will certainly find that pearl in the future: nothing is difficult in the world, only if you put your mind to it!" That night, Chen Jingrun couldn't sleep. He vowed that he would work hard at all costs when he grew up, whether he was successful or not!

Teacher-student relationship between China and Chen Jingrun

1985, 12 In June, Hua suffered a heart attack during his visit to Japan and suddenly fell to the ground in the forum of the University of Tokyo, ending his life of contributing to the cause of mathematics in his motherland. The news came that the whole country was sad and Chen Jing was ill.

Chen Jingrun and China

Running is so sad that he can't stop crying. He always said: "Hua Lao is gone, and so are my teachers who supported and cared for me." [5]

On June 26th, 0985, Hua's ashes were placed in Babaoshan Revolutionary Cemetery. At this time, Chen Jingrun was so ill that he could neither walk nor stand independently. The leaders and colleagues of the Institute of Mathematics advised Chen Jingrun not to go, but Chen Jingrun said, "Hua Lao is like my parents, and I am grateful as a mountain. I must see my teacher one last time. " At his insistence, his family helped him get dressed, put on socks and shoes, and others carried him downstairs. In Babaoshan, everyone suggested that he sit in the car first, and then help him bow to the urn of China's portrait after the ceremony, but Chen Jingrun insisted on standing in the gallery like everyone else. Because too many people attended the ceremony and were afraid that he would fall, three people had to drive, one left and one right, and one person held it behind. In this way, Chen Jingrun persisted until the ceremony of scattering ashes into the sea ended. The memorial service lasted for 40 minutes. He stood for 40 minutes. He was crying and crying for 40 minutes.

China is very kind to Chen Jingrun, and Chen Jingrun regards Huawei as "a teacher for a day and a father for life". Love between teachers and students is a beautiful talk in the field of mathematics.

1956, Xiamen University asked the Institute of Mathematics to hand over a manuscript to China. Hua received a manuscript from this young man who was similar to himself and suffered a lot. After reading it, he was very surprised and praised the young man. He was willing to use his head and think deeply. This young man is Chen Jingrun, who is as famous as Hua.

Recalling the days when I worked in the Chinese Academy of Sciences, Chen Jingrun said, I walked out of the narrow world of a school library and immediately placed myself in a specialized research institution where famous experts from all over the country gathered. My eyes are wide open and I feel like a duck to water. Under the direct leadership of the Party Committee of the Institute of Mathematics, with the kind guidance and help of Professor Hua, I fully appreciated the most advanced research results of number theory in the world at that time, which made my spirit refreshed. At that time, the Institute of Mathematics had many discussions on number theory. After some efforts, I have written many papers, such as the Waring problem and the integral problem in the circle. These achievements also condense the painstaking efforts of Hua Lao. He did a lot of work for me and revised my paper himself. Every step of my life is inseparable from the help and guidance of Hua Lao. It was Hua Lao's teaching and edification that inspired me to step by step to the forefront of analytic number theory. He is the teacher who trained me to grow up.

Hua's methods of guiding students are mainly self-study, assigning some books to read, attending some discussion classes, and talking to students about their majors once every two weeks on average. Under the leadership of authoritative people, people from different disciplines discuss the same topic, which is a very remarkable feature of Chinese studies and personnel training.

Selberg, a good friend of Hua, once said: "If Hua stayed in the United States after World War II, like many of his compatriots, there is no doubt that he would make more contributions to mathematics. On the other hand, I think China's return to China is very important. It is hard to imagine what China's mathematics would be like if he had not returned to China. " It is impossible to guess what China's mathematics will look like now, but one thing is certain. If Hua had not returned to China, Chen Jingrun's fate and experience would have been different.

While Chen Jingrun was working hard by taking advantage of the Institute of Mathematics, 1958, the national science and education system launched the so-called "white flag" political movement, and Hua, Zhang Zongsui and others were denounced as "big white flags" at the plenary meeting of the Institute of Mathematics. The focus of criticism is Hua's so-called bourgeois academic thought. Chen Jingrun was also implicated.

Hua not only gave Chen Jingrun academic guidance and help, but also taught his students how to face difficulties and setbacks and how to choose a life path.

During the Cultural Revolution, the Gang of Four sent Chi Qun to Chen Jingrun to collect black materials about China, and asked Chen Jingrun to expose China for "stealing his achievements". The evidence is that 1957, Hua's "On the Prime Number of Heaps" was reprinted, which absorbed Chen Jingrun's achievements. However, Hua wrote in the preface of the second edition of The Theory of Heap Prime Numbers: "I would like to take this opportunity to express my gratitude to Yue Minyi, Wei Daozheng, Chen Jingrun and other comrades who pointed out or gave help. Without their joint efforts, the second edition could not be published so soon."

Chen Jingrun politely refused ChiQun. He found Chen Dequan, a student of Hua Lao alone, and told him truthfully: "Chi Qun asked me to expose the so-called problem that Teacher Hua embezzled my achievements. What should I do? " This is a thorny issue. De-quan Chen suddenly think impassability Chen Jingrun's intention. He tentatively asked Chen Jingrun, "Did Teacher Hua steal your achievements?" Chen Jingrun decisively replied: "No" Chen Dequan secretly breathed a sigh of relief: "Then tell the truth, seek truth from facts anyway."

Chen Jingrun may not have a high political theory, nor will he use flowery words to express his love for teachers and the motherland, but his conscience tells him that there is nothing wrong with engaging in scientific research and respecting teachers. He decided never to do anything wrong to the party and the people, and never bite the hand that feeds him. When asked to expose Mr. Hua's plagiarism again, he flatly refused. Someone threatened him: "We have the witness material evidence." Chen Jingrun said flatly, "Since you have evidence, what do you want me to expose!" It was with his conscience and kindness that Chen Jingrun protected his teachers and safeguarded the interests of the Party and the country.

Later, Hua and Chen Dequan went out and passed the hospital in Chen Jingrun. Chen Dequan suggested visiting Chen Jingrun. Because of avoiding suspicion, Hua didn't get off the bus. He entrusted Chen Dequan to meet Chen Jingrun. After Chen Dequan came back, he conveyed Chen Jingrun's words: "Mr. Hua will always be a teacher, and Chi Qun never said anything like that."

From the late 1970s to the early 1980s, Chen Jingrun visited and lectured abroad twice. Out of respect for his teacher, he always goes to his hometown in China to say goodbye and ask for advice before each visit. Hua once said to Chen Jingrun and his entourage, "Jingrun's work is the best achievement we have made in the field of mathematics since the founding of the People's Republic of China." Chen Jingrun said modestly, "Thank you, Teacher Hua. You′re laying it on thick. It is the cultivation of Teacher Hua that has made me who I am today. " Mrs. Hua, who was sitting on the side, couldn't help interrupting: "Jingrun is diligent enough. You didn't come back just now, and he took out his book to read in a few minutes. " Hua looked at the students approvingly and nodded with satisfaction.

Hua is also very concerned about his proud disciple. On 1984, Hua was very excited and sad when he learned that Chen Jingrun had got it. He said: "You can't let Chen Jingrun get this disease that can't work!"

Before visiting Japan on 1985, Hua personally visited Chen Jingrun, a disciple who was hospitalized in the China-Japan Friendship Hospital, and said to him, "After examination by the director (Department of Neurology, China-Japan Friendship Hospital), I may be sick, too. When I return to China, we will all be hospitalized here. " Who knows, this side has become the final farewell of Chen Jingrun and Mr. Hua.

Chen Jingrun spoke highly of his teacher. 1973 In an interview with Xinhua News Agency, he praised his tutor Hua as a great mathematician and hoped that he would achieve more fruitful results in the study of number theory.

Google Logo commemorates Chen Jingrun's birthday.

It's a pity to spend too much time on math.

Hua seldom evaluates his students, not to mention that he has so many students. Improper evaluation can easily lead to misunderstanding. At most, he only speaks occasionally in individual conversations. Hua Zeng said to himself, "Among my students' works, what moved me most was (1+2). "When Wang Yuan mentioned some other pure mathematics achievements of his students, he still repeated:" What moved me most was (1+2) ".

Be interviewed

199 1 A reporter from the "I wish you success" column of Beijing TV once asked Chen Jingrun, "What is the purpose of life?" Chen Jingrun said: "It is dedication, not taking."
