Freshman students, who have just entered the university, are the most youthful and enthusiastic, and have a strong sense of honor, when they heard Kong Jidao say that, everyone felt that in the future it must be Liu Meng who solved Goldbach's conjecture, and several excited students shouted: "Liu Meng, please enter the Tao with mathematics and strengthen my reputation in China." ”

The shouts came and went.

Liu Meng kept calm, that was because he had solved the Sitapan conjecture by himself, and he himself understood the hardships best at the beginning, while Goldbach's conjecture was even more difficult than Fermat's theorem, and it was not at the same level as Sitapan conjecture, and the solution to this kind of problem was the same as enlightenment, there was a great deal of chance, maybe one day a flash of inspiration flashed, and he thought of a solution, and maybe he couldn't find this spiritual light for ten years, twenty years, or even a lifetime, and he was trapped in that step.

Liu Meng is unwilling to take this risk to solve such a problem, in the final analysis, the ambition is not here.

Kong Jidao saw Liu Meng's thoughts, and didn't say anything at the moment, and the classmates who were separated into several circles walked out of the second floor of the convenience cafeteria with Liu Meng and returned home directly.

Entering Kong Jidao's house, Liu Meng was startled, he knew that Mr. Kong's family had a lot of books on mathematics, but he didn't expect that he hadn't come for a while, there were more books at home, and there were almost everywhere full of books, such a large area of the house was full of books, and many books were opened and placed everywhere, and he couldn't help but sigh, how many books was Mr. Kong reading at the same time, and he was thoughtful.

Kong Jidao smiled: "I guess you also guessed, that's right." I'm working on the Goldbach conjecture. ”

Liu Meng was taken aback, in the cafeteria before, Teacher Kong said. Tomorrow's interview will let Liu Meng say according to this line of thought, he thought that Mr. Kong just wanted to fool the old scholars of the school's technical committee, but he never expected that Mr. Kong was really solving Goldbach's conjecture!

It's no wonder that Liu Meng was surprised, you must know that there is a law of forty years old in the mathematical world, even the thick and thin Wiles, he began to study Fermat's theorem when he was forty years old. And Mr. Kong is almost seventy years old now, and he has only started his research now, is it too late?

Seeing Liu Meng's doubts. Kong Jidao's face was extremely firm, and he said faintly: "Maybe you don't know the meaning of Goldbach's conjecture to me, when I was a teenager, it was when Chen Jingrun solved 1+2. The whole country was boiling. Since then, I have been studying the Goldbach conjecture, well, maybe I am really talented, and I have been studying it for more than 30 years, but I have never made progress, and even my personal problems have been delayed. ”

Liu Meng sighed for a while, but he didn't expect Goldbach's conjecture to have such significance to Kong Jidao.

"You don't know one night. How desperate I was, a dream I had been chasing since I was a child. As a result, one night, I suddenly felt that my pursuit was too ridiculous, and at that moment I felt that it was impossible for me to solve the Goldbach conjecture in my life, and all of a sudden, my world collapsed, and I lay on the bed with my eyes open, unable to find any meaning in life, the feeling of a broken dream, it was really more painful than death, swallowed up by a deep emptiness, hehe, I'm not afraid of your kid jokes, at that moment, I thought about suicide and ending my life, and this thought came out and scared myself. ”

Liu Meng probably can also understand that a person is too obsessed with pursuing one thing, devoting all his mind to it, giving up the ordinary life of marrying a wife and having children in the world, once he loses his faith, facing the cruel reality of old age, that moment must be very painful.

This is also why few mathematicians dare to think about the great conjecture of the century for decades, that is, Wiles, in line with the determination to counterattack with a sling, is ready to sink down to study Fermat's theorem for more than ten years, or prepare a paper in advance, and at one o'clock every year, the tenured professor will be done first.

Kong Jidao sighed, as if he didn't want to recall, "That night, I still feel very painful when I think about it, hard work and loneliness can't crush a person, but I lose my pursuit, I don't have a goal, just like the walking dead, I don't have a sense of zài." ”

"Hehe, fortunately, I was sensible enough, and finally I didn't do anything stupid, and then I began to devote myself to teaching, distraction, so that after a year, I finally got a sigh of relief from abandoning the Goldbach conjecture, and devoted all my energy to cultivating students with mathematical talents, except for reviewing a few mathematical journals, I no longer studied advanced problems myself. ”

Kong Jidao said, with a wry smile on his face.

Liu Meng suddenly realized, no wonder Kong Jidao's mathematical skills have not shown any papers that can be used, and he is famous in the domestic mathematics community because of teaching and review, and because of this, he also clashed with Hou Zhen of the Institute of Mathematics of Shuimu University.

"Teacher, why are you ......" Liu Meng didn't ask, but Kong Jidao already knew what he was going to ask.

"You want to ask me why I'm starting to study the Goldbach conjecture again, right? Speaking of which, you are the one who started it. Kong Jidao looked at Liu Meng with a smile, and his eyes were full of the love and appreciation of an elder for a junior.

Liu Meng pointed at himself, not knowing why.

"You kid likes to pretend to be stupid, with your brain, you can't understand anything. Kong Jidao scolded with a smile, "Those more than 30 years of research, although I have walked into a dead end and encountered an insurmountable difficulty, but over the years, although I don't think about it, those studies are like engraved in my mind, and I can't forget it. ”

"Then teacher, have you solved it like Wiles?" Liu Meng asked impatiently, with a trace of uncontrollable excitement in his tone, very happy for Teacher Kong, after all, this is a problem that has plagued him all his life.

Kong Jidao's expression darkened a little, shook his head, a wry smile on his face, and said: "How can it be so easy, have you forgotten it, Wiles struggled for six months because of a small flaw without any results, and almost gave up, and I just found an idea, an idea that may solve the difficulty, as for how to solve it, I haven't found it, hey, I think it's my talent is really mediocre." ”

Speaking of this, Kong Jidao had a deep helplessness, and his words were full of loneliness.

Liu Meng saw that he couldn't step through this hurdle in his heart, and he couldn't bear the pain anymore to study Goldbach's conjecture, but in fact, he still couldn't let go of it, once he had some ideas, he immediately started again, but mathematical research is an extremely brain-consuming and physical thing, Mr. Kong came to study at such an age, and he had to worry about his body, no wonder his complexion was so much worse.

It's like pursuing a girl, being rejected by the girl many times, until finally the girls are married, and the baby can play soy sauce, once I hear that people are divorced, I am still very excited, not to mention, in the heart of an obsessive mathematician, the beauty of mathematics is definitely much greater than the charm of a girl.

I wanted to open my mouth to persuade Teacher Kong, but Kong Jidao seemed to know what he was going to say, and asked first: "Liu Meng, you have an outstanding talent in mathematics, and you are the first person I have met in teaching in the past few decades, better than five me, or even ten me, how about it? ”

This is a great temptation, on the one hand, he is very passionate about mathematics, or he is still very obsessed, on the other hand, it is a great honor, even a sense of national honor, a young person is most likely to be enthusiastic, Liu Meng is no exception, and his heart is also eager, but reason tells him that this is definitely not the way he can go at present.

If you want to solve mathematical conjectures, you have to be like Wiles, hide in a small building and become a unity, and never ask what year it is, that is to be absolutely immersed in it, not to be disturbed and influenced by the outside world, to be absolutely calm, through guò a lot of relevant materials, to find that spiritual light.

Now Liu Meng is worried, and there are still a lot of ties, Pan'er, who doesn't know where he is, is still facing competition with the Du family, and he can't hide at this time.

At this time, I understand why Mr. Kong must hire himself as a researcher in the school, just to liberate him from tedious studies.

After thinking for a while, in the face of Kong Jidao's ardent expectations, Liu Meng could only make a difficult decision, opened his mouth, and was difficult to speak, but still said stubbornly: "I'm sorry, Mr. Kong, I can't calm down and think about Goldbach's conjecture now. ”

Kong Jidao was quite disappointed, sat down dejectedly, seemed to be a little older all of a sudden, after a failure and that sense of despair, in fact, he has lost his most precious self-confidence, he can't completely let go of Goldbach's conjecture in his heart, but he doesn't believe that he can solve this problem, and Liu Meng joined, but it can give him great confidence, and even, he thinks that as long as Liu Meng joins, with Liu Meng's imagination and his solid mathematical skills, he will be able to solve this problem that has plagued him all his life。

Immediately, Kong Jidao waved his hand, barely squeezed out a smile, and comforted: "It doesn't matter, the old man is indeed a bit strong, after all, you are still too young, and there are too many things to do, not like me, the only thing that I can't let go of is Goldbach's conjecture, well, then when you are free, come here, I will tell you about the research ideas and progress, maybe you will be able to solve it in the future." ”

Kong Jidao said very casually, but Liu Meng felt the loneliness in his words, and said with a smile: "That's a must, then, Mr. Kong, tomorrow will be examined by the academic committee, you can tell me about your research ideas and progress now, so that I can pass the test tomorrow." ”

Kong Jidao's eyes lit up, and he also felt that he was in a bit of a hurry, and his gloomy look was swept away, and he said with a smile: "Okay, okay, let's go to the study." (To be continued......)

ps: Kong Jidao, dedicated to preaching, lifelong pursuit.
