What do you think of Chen Jingrun?

However, what makes everyone feel anxious is the lack of Chen Jingrun spirit that once "touched China" in the contemporary era. Contribution and spirit-this is almost the most concentrated theme in the four-hour uninterrupted forum. Therefore, Academician Guo Lei, President of the Institute of Mathematics and Systems Science of the Chinese Academy of Sciences, said: "The significance of the symposium has gone beyond the institute and mathematics, involving the entire academic community in China."

As a mathematician, he represents an achievement.

1966 In May, Chen Jingrun announced that he had proved "1+2" in the Scientific Records, which was recognized by the mathematical circles at home and abroad and was called Chen Theorem. From 65438 to 0978, Xu Chi published an article "Goldbach conjecture" in People's Daily, which made Chen Jingrun a well-known hero in China.

On the 40th anniversary of the publication of 1+2 and the anniversary of Chen Jingrun's death 10, Lu Qikeng, an academician of China Academy of Sciences, commented: "Chen Jingrun's work is undoubtedly excellent, much better than that of our generation of mathematicians. His'1+2' work is a world record, which has been maintained for decades and has not been broken. That's not easy. "

A famous French philosopher said that Fermat's Last Theorem is the limit of human thinking, which cannot be solved by human thinking ability. But wiles solved it. However, Goldbach's conjecture remains unsolved. Lu Qikeng said, "Personally, Goldbach conjecture seems to be more difficult than Fermat's last theorem. Chen Jingrun's work is only one step away from the final solution of Goldbach's conjecture. However, this step is more difficult than going to heaven. From then on, Goldbach guessed to stay in Chen Jingrun. "

There were 1 1 academicians of the Chinese Academy of Sciences at the symposium that day. They are, Wu Wenjun, Lu Qikeng, Yang Le, Lu Ruqian, Ding, Yan Jiaan, Cui Junzhi and Guo Lei.

Experts present believe that Chen Jingrun's work not only represents the peak achievement of China's mathematics, but also represents a fine tradition. According to Wu Wenjun's memory and narration in some articles and works, the intention to solve Goldbach's conjecture was originally put forward by China. He once said, "Goldbach's conjecture is so beautiful that it has not been solved so far." On the basis of his work in China, Wang Yuan proved "3+4" and "2+3" in Goldbach's conjecture in 1955 and 1957 respectively. 1962, Pan Chengdong of Shandong University and Barba En of the Soviet Union independently proved "1+5" respectively; In 1963, the cooperation between Wang Yuan and Pan Chengdong proved "1+4".

Hua was sincerely pleased with the breakthrough with Pan Chengdong, but he said, "What moved me most was'1+2'."

Gao Xiaoshan, director of the Institute of Systems Science, Chinese Academy of Sciences, said: "This is the result of team work and a relay race." Wu Wenjun said: "We have such a tradition of tackling key problems together in mathematics, which should be valued, studied and carried forward in China."

"I still remember that night in March 1996, Wang Yuan and I visited Academician Chen Jingrun in Beijing Hospital." Yang Le said, "That was the last time we saw him before he died. Although Chen Jingrun has been away from us for 10 years, I think his height in mathematics and analytic number theory is a very important contribution to China's mathematics. Colleagues in the international mathematics community have long thought that Chen Jingrun's work is very difficult and incredible, and so far the evaluation of this achievement is very high. "

As a scientist, he represents a spirit.

Apart from his outstanding contributions, Chen Jingrun is most remembered and moved by his spirit. Cui Junzhi said: "He is a typical example of the' diamond fan' that the old dean Zhang Jinfu said." Anyone who has read Goldbach's conjecture is familiar with such a scene: in a 6-square-meter room, Chen Jingrun sits on a small bench and uses the bed as a desk, thus completing one of the most important tasks in China's mathematics field. After the Cultural Revolution, when his deeds were published, several generations were inspired by this spirit and determined to March to the peak of mathematics and science. Yang Le said, "I can easily count about 20 such examples myself. They are all scientists who have emerged after the reform and made important contributions in the academic field. When they met me, they said that it was Chen Jingrun's deeds and spirit that influenced them to embark on the road of science. "

Ma Zhiming said: "Chen Jingrun has a great influence on our generation. At that time, our worship of him was deeper than that of the current groupies. "

Wang Youde, a mathematician and winner of the National Science Fund for Distinguished Young Scholars, said: "I am a farmer's child. I don't know which university is good at math. I only know that Chen Jingrun graduated from Xiamen University, so I reported to Xiamen University. "

When Xiang Xiangyu, director of the Institute of Mathematics of the Chinese Academy of Sciences, went to the Institute of Mathematics for postgraduate study, Chen Jingrun was already ill. At that time, the atmosphere of TOEFL abroad had a great influence. He saw that Chen Jingrun, despite his reputation, was still working hard, and he knew that there were still many ways to learn math, so he didn't take the TOEFL.

Yang Le said, "I think Chen Jingrun's success lies not in his special talent, nor in his cleverness than others, but in his long-term diligence and hard work, persistence and hard work. Today, on the occasion of the 0/0 anniversary of Chen Jingrun's death, we commemorate him and learn from him, not only because of his contribution to China's mathematics, but also because of his long-term spirit of struggling and overcoming difficulties. In today's new situation, we must carry forward this spirit. "

Commemoration, for the sake of inheritance

In the 10 year after Chen Jingrun, China's economy developed greatly and its scientific research environment changed. However, has his spirit been better inherited and carried forward?

Yan Jiaan said: "Chen Jingrun only published dozens of papers in his life, but now some doctors have published more than 80 papers a few years after graduation. It is conceivable how serious the problem of study style is now. " When talking about the impetuous, superficial and grandiose "three floats" phenomenon in academic circles, Yan Jiaan warned: "This kind of atmosphere is very dangerous. If we don't pay attention to it and correct it in time, teachers will be impetuous, students will follow it, and students will pass it on to students after they become teachers. If this is passed down, more than one generation will be destroyed. " He said that the root of the problem lies in the management evaluation system and policy orientation, and the management department should pay full attention to this issue.

Ma Zhiming said: "When I was a graduate student, a sentence from Hua Lao (Hua) had a great influence on me:' Publish early and evaluate late'. I don't think anyone mentioned it now. Actually, we should. For example, Chen Jingrun published'1+2' as early as 1966, and people have the highest evaluation of this work until now. Now a lot of work has been evaluated before it is released, which really violates the laws of science. "

In Ding's view, "persistence without interference" is the reason why Chen Jingrun made an important contribution to mathematics. Looking back on Chen Jingrun's scientific research, he said, it is a miracle that he has made such great achievements under such strong external interference. Our current research work has also been disturbed, but this kind of interference is different from that in Chen Jingrun, and now it is the interference of individual awards and fund evaluation. But in any case, I hope that today's researchers will follow Chen Jingrun's example, concentrate on it and be undisturbed.

"If you are too anxious, you can't achieve great success." Cui Junzhi said: "We should not rush to make achievements, but do it honestly. The management department should strive to create a relaxed atmosphere so that people with the spirit of' safety drilling fans' can persist. "

As Ma Zhiming said, "the power of example is infinite". Yang Le thinks that although the present environment is more eager for quick success and instant benefit, the atmosphere of the research institute is still very good. This good atmosphere is a fine tradition inherited by mathematicians from China, Wu Wenjun, Feng Kang and other older generations to Chen Jingrun and other mathematicians.

Yang Le hopes that young scientists will learn from Chen Jingrun's persistent work spirit. "Long-term persistence will definitely achieve something. The significance of commemorating Mr. Chen Jingrun is that we should carry forward this spirit well and eventually make us an international mathematical power. " .
