“…… I think that the so-called science fiction is not literature, nor is it the place of science, and literary scholars enlighten people's minds, and the so-called philosophy is also thinking. Scientists educate people to move forward, and only hope that civilization will go ahead. However, the rise of science fiction has never been one of the two. Science fiction, with its unrealistic imagination, fantasizes about the development of human society, which is a reversal of the development of civilization. Scientific development has always required one step at a time, perseverance, and never made such a big stride. It is science fiction that has a lot of undesirable also.

Science and technology novels should serve the people as the main purpose, guide the people, and pass on knowledge to the people. and not a wild imagination..."—People's Liberation Army Daily.

"What do you think?" Junxin put down the newspaper in his hand and said to Wei Dong, who was sitting in front of him.

"I think what we young people need is to broaden our horizons, rather than following the path of our predecessors step by step. At the very least, we don't need to follow the path they have charted for us. Wei Donglai sat casually on the sofa in Junxin's office and said in a calm tone. He is also the only classmate who can communicate with Junxin on an equal footing so far. The others, including Junxin's three roommates, seemed a little cautious when talking to Junxin, which made Junxin a little uncomfortable.

"So you mean that science fiction doesn't have to be a carrier of technological development according to the old-timers' ideas?" Junxin walked over to the other couch and sat down, asking.

Wei Donglai nodded and said, "When I was studying in the United States, I had a discussion about the functions of science fiction, popular science novels, and scientific and technological academic papers. We unanimously agree that science fiction is an extremely important and indispensable article carrier that leads ordinary people to understand and imagine science; Popular science novels are a little more demanding, because popular science novels require popular knowledge, which has a little didactic flavor and tells people some general facts and principles. Scientific and technological academic papers are an important form of presentation of the development of advanced science and technology. ”

"There are three different articles, corresponding to three different scope of tasks, and no one can do without them."

Jun Xin nodded and said, "You mean to say that these seniors are now mixing the tasks of popular science fiction and science fiction, thus creating a certain rejection of science fiction, right?" ”

Wei Donglai nodded and replied, "Hmm." In fact, the two are not the same concept in the first place. Science fiction novels are actually literary novels, and popular science novels belong to science and technology novels, and the attributes of the two are inherently different. ”

"But this time Mengxue is in big trouble, although she also has a way to deal with it, but if she wants to complete her goal, I'm afraid the road to go is extremely difficult!" Junxin restrained the smile on his face and said a little worriedly.

Wei Donglai shook his head and said: "Don't worry, I don't think the eldest sister is so easy to defeat, since there is a response, then there will not be too much of a problem, after all, the champion of a province is not so easy to deal with." ”

"Again, I really should have faith in her." Junxin nodded and said.

The two chatted about some more topics, and then Junxin turned the topic to what Wei Donglai had been studying recently: "How is your thirteen-node kink table?" ”

Wei Donglai showed a hint of a smile on his face, and said, "I already have a clue and direction, I think it won't be long before I can make a kink table of thirteen nodes!" ”

Jun Xin nodded, his evaluation of Wei Donglai in his heart was a little higher, and after thinking about it, Jun Xin said: "The kink problem is actually a kink invariant problem to be solved in the final analysis. I asked you to make a thirteen-node kink table, the ultimate purpose is to find this invariant, you already have a clue about the thirteen nodes, it means that you already have a systematic understanding of kinks, I hope you can find the kink invariant as soon as possible. ”

"I discussed this with Professor Hu." Wei Donglai frowned and said, "Actually, Professor Hu is a little disapproving of me starting to study and research such a mathematical problem now. He hoped that I would be able to calm down and learn the existing body of knowledge. ”

"Professor Hu is right!" Jun Xin sighed and shook his head and said, "Your level has indeed reached the level of a graduate student, and this is the case with any scientific research, and at this level, it is time to think about your research direction." At this time, reading a wide range of professional articles is the fastest way. ”

"So what do you think I'm a good fit for?" Wei Donglai asked.

"Aren't you already sure?" Jun Xin smiled slyly, "When I first became a researcher at the Institute of Mathematics, the direction you chose to study was in the direction of mathematical physics, so you have actually already chosen your path, haven't you?" ”

"Hehe, too!" Wei Donglai laughed. After laughing, Wei Donglai couldn't help but ask, "By the way, you said that you wanted me to study kinks because of the needs of physics, is there anything special about this?" ”

When Jun Xin heard this, he was stunned for a moment, then shook his head and said: "The origin of the kink problem lies in a model of atomic structure, although it is no longer used. However, the problem itself is of great mathematical value and significance. It has a wide range of applications in physics. ”

"At the end of the nineteenth century, aether drift and blackbody radiation gave birth to the theory of relativity and quantum mechanics, respectively, which defined the movement of matter in the macroscopic world and the motion of particles in the microcosm. In the second half of his life, Einstein pursued a unified field theory of relativity and quantum mechanics. ”

However, Einstein himself did not determine what the unified field theory was. As a result, physicists have successively studied and given birth to the three standard models of modern physics: the Einstein field equation, the Yang-Mills equation, and the Higgs mass generation mechanism. However, the unified field has not yet been established. ”

"But I've developed something interesting in my recent studies of mathematics and physics. While explaining a strong interaction, Professor Venecino independently discovered that Euler's β function could be used to explain his research, and soon after, Leonat-Suskhan discovered that Euler's β function could be used to explain a jitter, twisted line segment, thus giving birth to a scientific physical model called string theory. I feel that this kind of research will be the focus of future physics research. Because I think this will be an opportunity to establish a grand unified theory. ”

"So, from the East, to study the energy lines in string theory, because it is analogous to elastic rubber bands, so kink will play an important role in the research, which is also my view on the kink problem, which is also exquisite."

"I see!" Wei Donglai nodded, although he was already shocked in his heart, his face was not showing anything. He nodded solemnly.
