Chapter 173: So intoxicated that the points skyrocketed! "Dean, don't be impatient! What he said may not be right! The academic report is not over yet!" Tan Ming was unwilling and nudged Shen Yanchun with his elbow. Shen Yanchun was refreshed. Yes, why should he feel sorry for himself? It was not uncommon for him to piss his pants when asked about academic reports. "I just don't believe it. He can convince all these people! Even if there is one person whose question he can't answer, he is wrong!" Tan Ming was already gritting his teeth. Hate it! The fame, status, and money that were within his reach would all disappear after today. How could Tan Ming not hate it? Lu Shan’s report started with the defects of topological semimetal semiconductor materials, and then talked about how to use mathematical logic to calculate various data and design various aspects, and each aspect has different methods. After knowing the calculation logic, the next step is to design the experimental process and, through detailed control of the experimental process, try to make the experimental results close to the model. Only in this way can the model and reality be logically consistent. So, Shen Yanchun and Tan Ming heard Lu Shan say this for the third time: "The first pair of Weyl semimetals (conduction band-valence band contact at a node): By analyzing the differential structure of topological defects, it is found that the Weyl nodes are monopoles in momentum space, which are three-dimensional topological defects. At these singularities, the Chern number is not well defined, and a topological phase transition occurs. There are also two-dimensional topological defects in Weyl semimetals, namely merons, whose topological charge gives the Chern number of the semimetal. The second pair of nodal line semimetals (conduction band and valence band are in contact with nodal lines): By analyzing the differential structure of topological defects, it is found that there are four-dimensional point defects in the system. At these singular points, the Hopf invariant is not well defined, and a topological phase transition occurs... I have made corresponding improvements to the places that need to be defined. These data are the test results that can only be obtained after conception and experimentation. I cannot elaborate on the specific methods because there is not enough time..."
In fact, it took more than an hour just to explain the general framework, which shows the complexity of this project. Even some of the more specific theorems involve hundreds of items, not to mention the derived combinations. However, all the people who came to listen to the lecture were talented people, and each of them had been working in this field for many years. When something was mentioned, they would start to deduce and fill in the blanks in their minds, which made Lu Shan very happy. His points jumped up rapidly, showing that every little detail inspired the people below. [Points: +2] [Points: +3] [Points: +6] …… If time was not really insufficient, Lu Shan really wanted to grab this group of people and tell them everything that happened last week, except for the most core details. Therefore, Lu Shan's words are concise and always go straight to the core, compressing the words to the extreme. It would be best if these people could remember some key points and quickly understand them after returning. If it takes them twenty or thirty years to understand them, what's the point for them? As Lu Shan spoke more, Shen Yanchun and Tan Ming's faces became uglier, because Lu Shan's logical chain was very long, but very reasonable, one link after another, without any flaws. The same is true for the external logic large loop and the internal logic small loop, and then the large and small loops form a perfect closed loop. "Why didn't Lu Shan tell us this logic?" Shen Yanchun looked unhappy. "If he had told us from the beginning, we wouldn't have taken other paths, right?" Tan Ming was very embarrassed. The team never told Lu Shan about the specific plan from beginning to end. During the meeting, they only informed Lu Shan sporadically. They always came up with a plan and then asked Lu Shan for the mathematical model. Lu Shan had made suggestions before, but Tan Ming and his team rejected them. "Well, maybe he didn't have complete logic at the beginning, and he improved it while doing experiments. Maybe he deliberately told us that we were wrong..." Tan Ming couldn't make up any more stories. Lu Shan always implemented their requirements perfectly, and there was no problem with the mathematical model he provided. The mistake was always in the experimental part. It was not until now that Tan Ming and Shen Yanchun became increasingly aware that there was something wrong with their thinking and that Lu Shan's approach was the right one. The results of my experiment were obtained by accident, and I am afraid it will be difficult to replicate. The experimental team has been on vacation ever since they came up with the idea, and they haven’t even done a reproduction experiment. The expressions of the team at the Xia State Academy of Sciences were even more complicated. This group of people were the smartest group of people in Xia State. They had been working on this topic for so many years. They had ideas, directions, and progress, but not much. After so many years and a lot of money, I didn’t expect that it would be finally solved by a young person, who is even from a different field! What kind of beast is this Lu Shan! This group of smart people provided Lu Shan with the most points, and their comprehension ability was much higher than others. At this point, Lu Shan had almost finished explaining the overall framework and began to talk about the details, although he certainly couldn't go too in-depth.
He could only take out some papers as examples and repeatedly point out the problems therein. This was a very clever move. The points increased sharply again. Specific analysis of specific problems is equivalent to one-on-one tutoring. If you are not inspired by this, then this person is probably just a slacker. As he was talking, Lu Shan took out the paper from Jiangzhou College of Materials and Chemistry. He didn't read it aloud, but the big screen was able to capture the cover. Moreover, in order to gain greater fame, Tan Ming enlarged the title of the paper and his own name a lot. This is inappropriate because all papers have writing standards, but this one did not have time to proofread, so it is presented here in its original form. Tan Ming was instantly furious. Was this going to be a public execution? "This paper is a typical error. It is a typical example of everything that seems to be right, and the combination is also right, but it is just wrong..." "Because its mathematical model is correct, every part looks normal. But if you look closely at the experimental part, you will know that this is not the case. The deviation is too large. It is impossible to be correct when so many parts are combined. The reason why the final result looks fine is actually a coincidence and cannot be reproduced. Let me talk about the specific logical errors in the paper..." Shen Yanchun thought: "It's over!" Tan Ming was dejected: "It's all over now!" People from other schools didn't think there was anything wrong. They came there just to listen to the report. Lu Shan was not targeting anyone. He could even speak frankly about his own school. He was extremely fair! Listen to how detailed Lu Shan describes the paper of our school's materials chemistry team! Tan Ming gritted his teeth. This Lu Shan just wanted to embarrass him! But Lu Shan really didn't have this idea, simply because he had experienced the whole process of Tan Ming's team, so it was easier to talk about it. What's more, the mistake is very typical. Other schools don't have such a good demonstration effect, so it's not so easy to increase points. The academic report lasted a whole day and was divided into two halves. No one was absent and everyone was fascinated by it. Even Tan Ming and Shen Yanchun benefited a lot. If they continued to work hard, they would be able to participate in the upstream and downstream of this industry in the future. However, other ideas emerged in Shen Yanchun's mind, and gradually formed in the process of listening to the report. The academic report ended and there was prolonged applause at the scene. Everyone witnessed this historic moment. Most people were proud, but everyone felt disappointed because, after all, this achievement was achieved by someone else first. But after listening to the report, I realized that I couldn't do it by myself. It might take many years to succeed, unless there was someone like Lu Shan. "Mr. Shen! Congratulations! Your school has won this pearl at the forefront of semiconductors!" "Lu Shan has really made Jiangzhou University famous this time. Talents like him should be cultivated well!" People who had met Shen Yanchun came over to congratulate him, and Tan Ming was quickly squeezed out of the circle and felt very uncomfortable outside. This honor should have belonged to him, but now that it has come to this, he feels ashamed to face anyone. I returned to Jiangzhou University on my own, and I probably won’t be able to get out of this shadow for a long time. Shen Yanchun forced a smile and joked with his colleagues. Suddenly, the crowd quickly dispersed and went in one direction. It turned out that they were all going to chase Lu Shan. Shen Yanchun was suddenly ignored and stood awkwardly in the distance. Looking at the crowd moving away, Shen Yanchun became more determined in his inner thoughts. This achievement is indeed Lu Shan's, but Lu Shan is also a member of the materials chemistry team. Without laboratory equipment, could he have achieved this result? Without Dean Shen's care, would Lu Shan be able to use the experimental materials? Although it is not used much, it is not something a student can get. Therefore, the hospital's care was the key factor in Lu Shan's achievement. In addition, Lu Shan was also a member of the materials chemistry team, and this achievement was obtained within the hospital. In any case, it can be said to be the result of the joint efforts of the hospital and Lu Shan.
Too many thoughts flashed through his mind, and Shen Yanchun gradually made up his mind. He would go back and slowly implement them. After the meeting, Lu Shan also held a small Q&A session for the people who followed him. He tried his best to explain their questions and answered on the spot those questions that scored higher points and took less time. Before he knew it, more than an hour had passed. Xia Guangming couldn't stand it anymore, so he stepped out to stop the crowd who were still eager to see more. "Lu Shan hasn't had a day off. If you have any questions, please email him and we'll contact you later. It's time for him to go eat now." Everyone looked at the sky and saw that it had already gotten dark, so they said goodbye one by one. Xia Guangming was the inviter, so naturally he would take Lu Shan to the meal. "What a promising young man! I didn't misjudge him!" Xia Guangming smiled sincerely and happily. The ones who came here to accompany him were the original core members of the Academy of Sciences team. They also came here spontaneously. These people frequently saluted Lu Shan, and Lu Shan responded with tea instead of wine. When Lu Shan was having dinner, he said that he didn't drink alcohol because it would affect his brain's thinking, so this group of people didn't dare to urge him to drink. If it was someone else, today's situation would be in trouble. Only talented people have the right to refuse boring social interactions. Xia Guangming has been looking for an opportunity to talk to Lu Shan about something. (End of this chapter)
