Chapter 189 He is truly a top mathematician, so refreshing!
In the next few days, Wang Hao did not go to the Science Foundation at all and focused on the research of the newly established mission.
But he still went to a place--
Shuimu University.
Qiu Chengwen invited him to Shuimu University to give a report on Goldbach's conjecture, and giving the report was also planned.
This time is just right.
The newly created task is, after all, C-level research, and it is still difficult to complete alone.
Wang Hao went to Shuimu University that day, and was greeted by several people at the door. They had already met him two or three times, and they went in with a polite gesture.
After he met Qiu Chengwen, he exchanged greetings and the time was almost up.
The report on Goldbach's conjecture research does sound very influential. In fact, because he published two papers, the difficulty of the argument is not as high as expected. With enough basic knowledge, you can slowly understand it.
Already.
Shuimu University did not do much publicity about this. Not many scholars came to listen to the report, and most of them were doctoral students at the school, and even some were studying for master's degrees.
Of course, it would be difficult for them to understand everything.
Wang Hao did not intend to explain it in too detail, because the proof is already there, and some detailed calculations and derivation do not need to be explained in detail.
This report focuses on computational analysis methods, which is the second proof paper published in Acta Mathematica Sinica.
The proof of the computational analysis method is more straightforward than the covering method, but the process of analysis and comparison seems very brain-burning, unlike the covering method which is as 'flexible in thinking'.
So what he explained was the overall content, and some detailed processes were taken through directly.
That part of the content can be understood if you think about it slowly.
"Many mathematicians have taken detours when it comes to Goldbach's conjecture."
Wang Hao said, "The computational analysis method is a method that many mathematicians have considered, but perhaps because the analysis in the middle is more complicated, they subconsciously feel that it is impossible to complete."
"This analysis process is indeed complicated, but it is not completely impossible to do."
"Let's look at the difficulties. The first is the comparison content in the first part..."
Facing the hundreds of people in the audience, Wang Hao began to explain seriously.
Wang Hao didn't pay much attention to the report on Goldbach's conjecture, because there were some top scholars in the audience who had already understood the proof process, and there was no need for him to explain it in particular.
Therefore, he is targeted at people who have difficulty understanding the proof process.
Most of these people are PhD students, graduate students, or ordinary assistant professors. We only need to explain the difficult points to them.
At the same time, what Wang Hao is most concerned about is research progress.
Although the proof of Goldbach's conjecture has little relevance to new research tasks, it can still provide a certain amount of inspiration.
This is the most important.
[Task three, inspiration value +2.]
[Task three, inspiration value +4.]
[Task three, inspiration value +1...]
Compared with the difficulty of C-level tasks, the rate of increase in inspiration is not fast.
But, it's enough.
After completing the report on Goldbach's conjecture, Wang Hao looked at the inspiration value again and found that it had reached '109'.
"Finally finished!"
He couldn't help but smile.
The entire venue burst into warm applause. Wang Hao walked off the stage amidst the applause and exchanged a few words with the people in the front row.
Qiu Chengwen listened to the entire explanation and said with admiration, "Wang Hao, I found that your explanation ability is really not inferior to your scientific research ability!"
"I have always felt that young mathematical geniuses are not good at explaining or educating. Your course must be very popular, right?"
"It's okay~"
Wang Hao was a little embarrassed to be praised in this way.
"It must be very good." Qiu Chengwen smiled and said, "There is an associate professor in our center named Xu Lei who is less than thirty. You have met him once. He is mainly engaged in the research of curves and topology. He is a genius."
Qiu Chengwen's comment of "very genius" is obviously not an ordinary genius.
He continued, "Xu Lei, it's okay to do research on your own. He opened a course and more than a hundred students signed up, but after a month, more than ninety gave up."
"Students all said they couldn't understand in class. I asked him specifically about this. He didn't understand why the students just couldn't understand the simple logic that just passed by."
He laughed even as he spoke.
Wang Hao said, "This is also normal. It is difficult for ordinary people to understand geniuses, and it is difficult for geniuses to understand ordinary people."
"That's why I said, you are very powerful." Qiu Chengwen said, "It is rare to have two-way development in scientific research and teaching."
"Thanks."
Wang Hao doesn't have any special feelings, because his focus is on teaching.
What Qiu Chengwen said reminded him of his own courses, and he suddenly felt a little regretful, "I missed several classes when I came to the capital!"
"What a pity……"
…
Science Foundation.
This day is a formal meeting to communicate gravity research.
In the morning, many people came, all figures related to the superconducting field, and they all went to the conference room behind the main building.
Wang Hao, He Yi and others also passed directly.
When he arrived at the door, he saw a somewhat familiar face.
Xiang Qiansheng.
Xiang Qiansheng was a little embarrassed when he met Wang Hao. They had only met once, when they came to the capital last time, and Wang Hao scolded him out of the conference room.
The impression that time was so profound!
Xiang Qiansheng still remembers it very clearly, but when he saw Wang Hao again, he was not so angry because he knew that he had lost.
At that time, he just wanted to get a chance to compete for a project, and he did get it.
However, the research done by his team still cannot keep up with that of physics laboratories.
What else is there to say?
Xiang Qiansheng sighed, walked over, and took the initiative to extend his hand, "Professor Wang, you are here, your research is so good, I am convinced!"
The last sentence was spoken from the bottom of my heart, and my sigh was clearly revealed.
Wang Hao smiled and said, "Thank you."
Xiang Qiansheng's expression was a little decadent. What he lost was not just a piece of research, but also the future of his life.
As a member of the Superconducting Laboratory of the Academy of Sciences, he has received support from the laboratory and more than 10 million yuan in funding, which is not something he talks about casually.
That was not a grant from the Science Foundation, but a grant from the Superconducting Laboratory.
However, leading the team to do research failed to meet expectations in the end, which meant that everything was in vain. It would be almost impossible to lead the team to do large projects later.
Anyone doing laboratory research cannot do without the support of the laboratory. For example, only the top scientific research institutions can apply for large national projects.
Xiang Qiansheng thought about it, then looked at Wang Hao and couldn't help but shake his head.
That is only for ordinary people. Super geniuses like Wang Hao do not need to rely on the platform of a large laboratory at all.
And I am just an ordinary person.
…
The meeting officially begins.
There were about thirty people attending the meeting, half of whom were from the Science Foundation.
Seven people came to the Basic Science Center of Capital University, which was the second largest number of people. Others included people from the Superconductivity Laboratory and Physics Laboratory of the Academy of Sciences, and the rest were a few sporadically invited authorities in the field of superconductivity. .
The meeting was organized into separate groups.
Everyone in the Basic Science Center is sitting together.
Wang Chenglin and Jiang Jian were next to each other, and they were whispering, "Jiang Jian, what you said that day was very good. We at the Basic Science Center are here to compete openly."
"The primary and secondary projects must be clearly distinguished. If our direction is better, it will naturally be the primary project."
Wang Chenglin said, "In terms of research on superconducting mechanisms, they are indeed a new direction, but they are subject to confidentiality restrictions. They cannot do research on AC gravity. The main direction can only be comparative research on superconducting mechanisms, which is the same as ours." "
"Our research is more professional."
"In this regard, it will be beneficial for us to let them cooperate with the experiment."
Wang Chenglin got involved in AC gravity research and thought a lot about it. They were doing research on the mechanism of superconductivity. Specifically, they were studying the quantum state distribution characteristics of the superconducting state.
This is research on ‘condensed matter physics’.
Research in this direction requires continuous experiments to prepare high-quality Josephson junctions with atomically flat interfaces.
If there is an AC gravity experiment, it can assist in providing data as a reference, which may be very valuable in constructing quantum state wave function distribution research.
While the two were talking, the meeting officially began.
First of all, it was Academician Wu Hui from the Superconducting Office. He gave a research explanation on AC gravity, explained the AC gravity experiment, and explained the subsequent comparative experiments. At the same time, he also greatly praised the work of the physics laboratory.
Next, other professors from the Superconducting Laboratory stood up to summarize the discussion some time ago and expressed a series of ideas and directions.
Then, the key point comes.
As the two largest research institutions on superconducting mechanisms in China, the Basic Science Center of Capital University and the Superconducting Laboratory of the Academy of Sciences respectively explain the main directions of research and development and recent progress.
The project of the Superconducting Laboratory of the Academy of Sciences has been carried out for more than ten years. I will only briefly talk about the recent achievements and progress.
The project of the Capital University Basic Science Center is brand new, but their results are very significant.
For example, an ultra-thin high-quality Josephson junction with an atomically flat interface was prepared, and the relative rotation angle of the superconducting layer was precisely controlled.
At the same time, some inferences are also made based on this.
Jiang Jianzuo reported, "We believe that the d-wave pairing theory is not applicable to the bismuth strontium calcium copper oxygen high-temperature superconducting system..."
"We will extend our existing research to other cuprate high-temperature superconducting systems to study the applicability of the d-wave pairing theory."
"We are targeting Josephson coupling between two single-layer cuprate superconductors at the atomic limit..."
"..."
Jiang Jian's report lasted almost twenty minutes, and he always talked about very professional content, including their research and development direction, progress, inferences, and even upcoming research.
Although the content of the explanation was very professional, everyone present was an expert in the field of superconductivity, and they all understood that their research had made great progress, and the main research direction was indeed eye-catching.
This is like constructing the standard model of particles, adding content bit by bit, and sooner or later it will take shape.
However, it is difficult to say the specific rate of progress, as similar research has physical limits.
There is progress now, but it does not mean that there will be progress in the future, nor does it mean that if the accumulation reaches a certain level, theoretical breakthroughs can be achieved. When will it be able to support the application field, it seems a bit far away.
However, everyone present still spoke highly of the research of the Basic Science Center.
For international comparison, relevant research can only go so far.
Next it’s the physics lab’s turn.
This conference is also aimed at the research of communicative gravity, and the physics laboratory is the protagonist.
First of all, He Yi stood up and gave an explanation, explaining the AC gravity experiment, the novelty of the experiment, and the theoretical mechanisms related to superconductivity that can be studied and explored by studying the relationship between AC gravity fields and superconductivity.
After that, Wang Hao stood up. He looked at everyone present and said seriously, "We also focus on the superconducting mechanism, but the research method is completely new."
"Traditional research on superconducting mechanisms focuses on exploring the physical states of superconducting condensed matter and studying atomic fluctuations in quantum states."
"This direction cannot be said to be wrong, but it is difficult to achieve the leap from theory to application."
"The current theoretical research and applied research on superconductivity are like two completely different directions. Many applications do not require theoretical support at all."
Wang Hao walked out of his seat and said as he walked, "I read the latest research on superconducting materials, a new type of binary metal compound. How was this material discovered? The research team conducted various materials research at ultra-low temperatures.
It was obtained through experiments, so my understanding should be correct, right?"
Everyone in the venue nodded along.
Most of the new superconducting materials are discovered in this way.
"So." Wang Hao said, "At this stage, it can be said that the theory in the field of superconductivity is still catching up with its applications. We don't even know when we will catch up, let alone surpass it."
"Studying the physical properties of superconducting condensed matter cannot be said to be wrong, but it is difficult to see the end. It involves quantum physics, which is like studying the standard model of particles. This direction is very attractive, but gathering all physicists,
It’s unclear how perfect it must be to be relevant to reality and not just limited to theoretical physics.”
Wang Hao walked to the big whiteboard on the side, picked up a pen, and then continued, "So I want to study the superconducting mechanism through another way, and that is..."
"math!"
After hearing what Wang Hao said, everyone in the conference room looked at each other.
Condensed matter physics certainly contains mathematical content, and the explanations of various quantum wave state analyzes use mathematical methods.
Wang Hao wrote a determinant on the blackboard unhurriedly, and then explained, "The mathematics I am talking about is not a mathematical method, but a mathematical model for establishing the superconducting mechanism."
"Establish a mathematical model of superconductivity based on experimental data, and combine it with AC gravity and other experiments to slowly improve this model."
"The specific structure is like this..."
Wang Hao started writing.
This is the result of his research. Based on the AC gravity experimental data, he constructed a mathematical model of the superconducting mechanism, that is, using mathematical methods to explain the relationship between various parameters.
If the mathematical model can be improved to a certain extent, the relationship between material properties, superconducting state triggering mechanism and temperature can be understood.
Theoretically, many materials can be classified as 'superconducting materials'. The only difference is that the temperature to achieve the superconducting state is different. Some can even trigger the superconducting state when it is extremely close to absolute zero.
By using mathematical means to explain the relationship between material properties, superconducting state triggering mechanism and temperature, we can rely on theory and material properties to determine the superconducting state temperature.
In this way, we can also deduce what kind of materials are high-temperature superconductors, and we can even study what kind of materials can achieve "normal temperature superconductivity".
Of course, the latter is difficult.
However, in the research direction of the theoretical mechanism of superconductivity, the method of establishing mathematical models is definitely feasible, and Wang Hao is very firm on this point.
"Using mathematical means to describe the superconducting mechanism can directly understand the relationship between material properties and superconducting temperature in a numerical and symbolic way. This can be realized in the future and provide direct theoretical support for application directions."
"I think this path is more valuable than studying the physical properties of superconducting condensed matter!"
After Wang Hao finished his explanation, he made a conclusion with certainty.
Everyone in the conference room stared blankly.
They just followed Wang Hao's ideas to understand. Even though it was a little obscure and difficult in the middle, they understood the general process.
Based on AC gravity experimental data, Wang Hao established a mathematical model that integrates complex parameters such as AC gravity field, material properties, and structure.
How complex a job is this?
Many people feel their scalps go numb when they think about it, but Wang Hao not only made it, but also made it logically. At least they can't find the mistake.
If we can continue to improve it, we will obviously be able to slowly describe the relationship between complex parameters.
To put it simply, it is like a multi-parameter word problem.
Parameters include x, y, z, a, b, d...
Each experiment can provide the relationship between parameters, and a corresponding equation can be established.
As you continue to experiment, you can establish a system of equations. With enough equations including all parameters, you can naturally solve them accordingly.
Then, is it ok?
It sounds very simple...a P!
Many people couldn't help but twitch their lips. Just listening to Wang Hao's explanation just now, they knew that 'establishing equations' is a very complicated mathematical task, and there is a high probability that no one else here can do it.
The only one who can do it is Wang Hao himself.
If the mathematical work Wang Hao just conducted is correct, it means that the direction he mentioned is correct. It does sound much more relevant than studying superconducting condensed matter physics and related applications.
This is a very good direction!
No one here dared to question Wang Hao's mathematics, and naturally no one questioned the direction he said.
People at the venue reacted and applauded together.
Somewhat unexpectedly, it was Xiang Qiansheng who was the first to express his stance. He said with admiration, "This direction is unprecedented, and I think there is great hope!"
A professor next to him also said, "I think so too. A new direction, a new idea, using mathematics to understand superconductivity and directly explaining the relationship between each part is better than studying condensed matter physics and studying a, b, c, d."
Waves have a lot to do with applications!”
Academician Wu Hui also applauded, "It's very novel and very interesting!"
"Wang Hao is indeed one of the top mathematicians in the world. He is very refreshing to us!"
Others also praised him.
At the same time, some people had very complicated moods. Wang Chenglin frowned and looked at the content on the whiteboard, and then looked at Wang Hao, who was surrounded by people, and he knew that his idea could not be realized.
He hoped that the physics laboratory would cooperate with the basic science center, but Wang Hao proposed a completely new research direction. He also studied the theoretical mechanism of superconductivity, but skipped condensed matter physics directly.
This direction is spoken out and is recognized by many people.
Wang Chenglin felt that the direction mentioned by Wang Hao had great potential, and that it might be possible to jump from theory to application. He was even thinking, "Should we also find a mathematician to focus on research in this direction?"
But gave up immediately.
How can it be so easy to find top international mathematicians?
Even if one were to be recruited reluctantly, it would be impossible for him to be at Wang Hao's level and be able to directly establish a mathematical model based on a large amount of complex experimental data. Just think about it and you will know how difficult it is.
The current situation has become that the physics laboratory has found a new direction, and it is also favored by many people in the venue.
What should they do?
Take the initiative to cooperate with research in the physics laboratory?
Do not make jokes!
Even though he was interested in Wang Hao's research direction, Wang Chenglin couldn't keep his face down at all. When he looked at Jiang Jian again, he felt a little angry.
It’s all this guy!
What did he say at that time, that he represented the Basic Science Center and actively cooperated with the physics laboratory? Could he represent the Basic Science Center?
Is it possible to say this casually?!
When Wang Chenglin was thinking about it, he saw Wang Hao walking towards him.
He took the initiative to stand up and said with a forced smile, "Professor Wang, congratulations on finding a new direction in the research of superconducting mechanisms. The future is limitless. I look forward to the day when you can realize the transition from theory to application in the field of superconductivity."
"That's still far away!"
Wang Hao shook his head and said, "The direction is just a direction. It's hard to say when we will have results. We are just a separate laboratory."
"Speaking of this, I remembered that Professor Jiang said that you will cooperate with our research direction to carry out experiments. I still have to ask for it in the future."
"..."
Jiang Jian was embarrassed.
Wang Chenglin could only wave his hands and said, "It's not the same direction, we are not the same direction." He looked at Wu Hui and said, "Academician Wu, the main direction has been determined, and it has nothing to do with us. My laboratory is very busy, so let's go first
gone."
After he finished speaking, he turned around and left the conference room without waiting for Wu Hui to nod.
Jiang Jian simply turned around and followed him.
Wu Hui shook his head funny.
Wang Hao turned to Wu Hui with doubts and asked, "Did Jiang Jian say that he represented the Science Center at that time in vain?"
“Generally scholars attach great importance to face.”
Wu Hui said amusedly, "But when scholars become scoundrels, who can do anything to them? After this time, it is estimated that Wang Chenglin will not attend industry meetings for a long time."
"Uh~~"
"That makes sense."
Others nearby also laughed.
I see a lot of people commenting on the previous chapter. Maybe the author's feelings are different from those of the readers. That chapter was really written very seriously and was all about direct scene descriptions.
If you do narration regularly, it will be much easier to write~~~
