Chapter 164 The significance of the first prize in natural science, NS equation
New breakthrough!
Wang Hao arrived at Shencheng Aircraft Design Institute at 9 o'clock in the morning, and the official start time of the lecture was 10 o'clock, so the time was still tight.
After chatting with everyone, he went to the back to get ready.
The lecture is arranged in the large conference hall on the first floor.
In the office next to the conference hall, Wang Hao, Li Jianhua, Zhao Xin and others sat together and talked about the lecture report.
Last time at Xihai University, Wang Hao gave a very serious explanation, but Li Jianhua, Zhao Xin and others couldn't understand it.
Li Jianhua was deeply impressed by this. He tactfully said to Wang Hao, "Professor Wang, can you explain it more carefully this time? Your method is really..."
“It’s too difficult!”
Because he knew the importance of the content, he didn't want to lose face, so he wanted Wang Hao to explain it in more detail.
"Don't worry, I will explain it in more detail." Wang Hao said.
Li Jianhua looked around and didn't see Wang Hao taking out anything. He asked strangely, "Are you prepared for anything?"
"What preparation?"
"For example, some information..." Li Jianhua was a little worried, because he didn't see any information, so he thought Wang Hao had no preparation.
Wang Hao pointed to his head and said with a confident smile, "It's all here."
Before coming, Wang Hao also thought about preparing some information, but later found that it was not necessary at all.
The set of equations given by Cui Xunnian was enough for him to practice. He completed six sets of approximate solutions in a row. In the process of constant substitution and transformation, it can be said that the application of the new method was pure.
This method was researched by himself, and everything has been imprinted in his mind.
In addition, he only explains how to use it, so that others can know how to use it. Naturally, there is no need to prepare anything in particular, everything is already understood.
However, Wang Hao thought about it and still planned to have time to write a summary and analyze the underlying logic of the entire derivation. Even if it is not published, he can still submit it for confidential research and seal it.
This may be of reference value to other people's research.
After all, there is no guarantee that his research cannot be surpassed by future generations. It is even said that there will definitely be future generations who can surpass it or improve the methods he developed.
If there is no relevant derivation content at all and only the solution method is taught, it is equivalent to technical application without a theoretical basis, and there is no room for improvement.
Wang Hao thought about it and said, "Mr. Li, don't worry. I estimate that this lecture will take at least six hours."
"Six hours?" This length of time surprised Li Jianhua. He thought it was just a lecture of one or two hours, and he was not even sure that there would be content in the afternoon.
Wang Hao said, "Six hours may not be enough," he said very seriously, "Although it is unlikely, I hope everyone can understand it."
It was just a simple sentence, but Li Jianhua was very moved. He did not expect that Wang Hao would attach so much importance to the lecture.
Some scholars are invited to give lectures. During the lecture, they don't care whether the people below can understand them. They even say that they feel that the people below them can't understand them, which further proves their erudition.
This is not just one or two scholars, but many scholars are like this.
For example, at some academic exchange conferences, some experts go up to give presentations without caring about how many people can understand them.
As long as top experts can understand it and make a judgment, that's all.
Wang Hao would rather talk for a while by himself. Li Jianhua was really moved. He found that Wang Hao really hoped that more people could understand, instead of just talking verbally.
In fact, Wang Hao will of course pay attention to the lectures. Only if more people can understand them can they give back more inspiration and knowledge, so as to achieve new breakthroughs in the research of ns equations.
Of course, at the same time, he really hopes that more people can understand it.
After all, it is your own research, and spreading it to more people can be considered a personal achievement.
…
Soon, the lecture began.
Many scholars came to this report.
Wang Hao stood on the podium of the conference hall and looked at the crowd. It felt a bit like a large classroom in a school. It was roughly estimated that there were more than a hundred people.
The number of people over a hundred does not seem to be many, but considering that there are top scholars in the audience, and many of them are experts in aerodynamics and fluid mechanics, the situation is completely different.
Of course, it is inevitable that some people come to join in the fun.
In Wang Hao's eyes, Li Jianhua is a type who joins in the fun, because Li Jianhua is engaged in overall aircraft design and leads a team in aircraft design projects, rather than specializing in aerodynamic research.
In the field of aerodynamics, his level is at most higher than that of ordinary Ph.D.s, and may not even be able to catch up with ordinary Ph.D.s. He just knows more about applied research, and there must be considerable deficiencies in his foundation.
There are many scholars in the audience who are in a similar situation.
They may be experts in a certain field, but as long as they do not specialize in fluid mechanics, aerodynamics, or use relevant equations, it is almost impossible to understand the report.
Industry specializing in surgery.
This is especially true in the fields of science and mathematics.
Even for a top academician, it is difficult to cover cross-field content, or even non-main research fields. His ability level is comparable to that of a doctoral student, which is already quite good.
After the venue quieted down, Wang Hao stood on the stage and said, "Today, I am honored to be invited by Mr. Li Design to come here to give a lecture report."
"This is a research report on my direction of solving partial differential equations and NS equations."
"I don't know much about aircraft design, and I have no special research on aerodynamics, but I have some personal understanding and research on NS equations and partial differential equations."
"General Design Li believes that my research is very helpful for calculations related to aircraft shape design, so I am here."
"I think everyone is not here to listen to polite words. Let's get straight to the topic."
After Wang Hao said with a smile, he wrote two lines of content on the whiteboard, which are two titles - "Finding Approximate Solutions to Partial Differential Equations" and "Comparative Analysis and Correction of Replacement Equations and Original Equations".
"I divided the research into two parts. The first part is the method of obtaining approximate solutions to partial differential equations. I will explain it in the morning. This part of the content is relatively simple. I believe that most people can understand it.
.”
"The latter topic is the comparative analysis and correction of the replacement equation and the original equation. It will be explained in the afternoon. This part is relatively difficult, but it is also the most important part of the calculation."
"Let's start the first part of the explanation."
"..."
Wang Hao began to talk seriously. He seemed to be in a teaching class, acting very casually, but his explanations were very detailed.
The people in the audience also listened carefully.
They found that Wang Hao's speech was very slow, and it was just an introduction to calculation methods. It was indeed easy to understand.
However, some people still find some parts obscure and difficult to understand. They can only use a pen to make notes and write down the conclusions before they can continue to listen.
There are also some that I no longer understand after a while.
Among them is Li Jianhua.
Listening to the explanation again this time, Li Jian knew why he couldn't understand it. It was because he had no relevant mathematical foundation, or in other words, he had forgotten it long ago if he had any foundation.
Without a foundation, no matter how detailed the explanation is, it is impossible to understand some of the conversion steps.
Li Jianhua felt very depressed. He always thought that he had some research and understanding on aerodynamics, but when he encountered very professional and complicated problems, he couldn't even understand them even if the other party explained them in detail.
There are also some people who can't keep up quickly, but the reason for not keeping up is not that they can't understand, but that they got distracted during the lecture, or they said something to someone else, and then they couldn't keep up again.
.
They couldn't help but whisper to others, "Why are you here? What were you talking about just now? How did that transformation come about?"
No one answered.
Many people have found that the content explained by Wang Hao is very difficult, but they can still understand it if they listen carefully.
It would be different if you were distracted.
That's what mathematics is like.
In a whole logical system, if you fail to follow one step, it will be difficult to understand the rest. However, the lecture on the stage will definitely not stop, nor will it be explained by a single person.
Wang Hao was explaining carefully on the stage.
He hoped that everyone could keep up. There were some difficult points to understand, and he emphasized them several times in succession. However, some people still couldn't keep up, so there was no good solution.
He could only keep emphasizing, "If you didn't understand what you just said, just write down this conclusion and treat it as a definition or formula."
After saying this, continue.
The whole process was really like giving a lecture to students in a classroom, but no one cared about it at all. They had no time to think about other issues and just listened carefully.
But overall, as Wang Hao judged, the content in the morning was relatively simple.
Even if you don’t understand something, you can still write down the conclusion and continue listening.
…
noon.
Wang Hao was invited to have lunch, and then went to the lounge to take a nap.
He did feel a little tired because he had an early morning flight and came directly to give a lecture after arriving.
I slept for nearly two hours.
After waking up and stretching my body, I regained my energy a little. At half past two, I arrived in the conference hall again.
Many people are already waiting there.
"The content in the afternoon is the comparative analysis and correction of the replacement equation and the original equation. This content is more difficult than in the morning."
Wang Hao's first sentence gave everyone a shot, "It involves some very difficult mathematical analysis methods in discrete mathematics and functional analysis."
"If any of you don't have the foundation, you can write down the conclusions first without trying to understand the whole content."
This part is the most difficult. Wang Hao even thinks that no one can understand everything.
He already has an understanding of the level and capabilities of the experts in the audience.
These experts are engaged in aerodynamic research, but most of it is applied research rather than theoretical research. They also rarely study other partial differential equations, let alone some advanced analysis methods.
There are definitely some very high-level experts among them, but most of them have not touched on so many fields.
In addition, some experts are already older and they cannot consume so much content in one go. Even if they have the basics, it is difficult to keep up with them all.
Therefore, it is a good method to memorize some conclusions first and then try to understand them, instead of wasting a lot of energy on difficult to understand areas.
After Wang Hao finished speaking the preface, he began to speak seriously.
Because the content involved is relatively difficult, the explanation is more detailed than in the morning.
Everyone in the audience listened very seriously. Some of them just came to join in the fun, but after knowing the content, they knew that they must master this method.
What Wang Hao talked about is directly related to aircraft design. After mastering this method, related calculations will not be a problem.
At the same time, they also understand the value of content.
At first they heard that 500,000 yuan was used to invite people to give lectures, and they thought they were being taken advantage of. But after knowing the content, they felt that it was not possible to buy people with this method, not to mention 500,000 yuan, millions, or tens of millions.
possible.
This is directly related to the appearance design of the aircraft.
The more accurate the relevant calculations are, the more flexible and better-performing aircraft can be designed.
If the performance of each aircraft can be improved, how much value will be created?
Nowadays, the manufacturing cost of a top-notch fifth-generation aircraft is calculated in units of "hundred million". Even if the performance is only improved a little, the value created can be said to be massive.
When everyone is serious, Wang Hao is more motivated to explain. At the same time, he also finds that the inspiration value of the NS equation research task is constantly increasing.
This made him more energetic.
"Here we need to continue to compare with the parameters of the original equation..."
"Let's set up a set, which is a parameter comparison set..."
"This step requires drawing and analysis."
"There is no need to specifically shape the function, but we must try to ensure the smoothness of the graph."
"The smoothness here does not refer to the smoothness of the solution set, but to try to ensure that the solution is around this curve..."
"..."
The method explained by Wang Hao becomes more difficult as it goes on, and the speed of his explanation becomes slower and slower. Each step takes a long time.
At this time, Li Jianhua also understood why Wang Hao said it would take at least six hours. The following content was too difficult, especially the content involving mathematical analysis.
It’s just calculation, comparison, and analysis. There are many steps not to mention, and each step also involves very profound mathematical analysis methods.
He no longer understands it. Just looking at the complex diagrams and diagrams on the whiteboard makes his head spin.
finally.
The four-and-a-half-hour lecture is over.
After Wang Hao said the last sentence, his voice became a little hoarse.
He quickly took a sip of water and said with a wry smile, "Just wait until tomorrow to ask questions. I really can't hold on today."
“I changed my flight to an early morning flight, and I’m too tired now.”
"But it doesn't matter. I plan to stay in the provincial capital for three days. If anyone has any questions, you can ask me tomorrow or the day after tomorrow."
…
End of report.
Wang Hao went to the hotel to rest immediately and waited until noon the next day before he felt recovered.
"Half a million, it's really hard to make money!" He got up with emotion, and after lunch he was taken to the Aircraft Research Institute.
There are many people already waiting.
Now we are continuing the questions from yesterday’s report. He answered everyone’s questions patiently, as if he had completed a piece of work, but he also gained something in the process of explanation.
[Task 1, inspiration value +1.]
[Task 1, inspiration value +1.]
Seeing the increasing inspiration value, Wang Hao also felt very motivated and even thought about staying a few more days.
at the same time.
A team of experts from the Department of Mathematical and Physical Sciences returned to the capital.
He Yi, Xiao Xinyu and Yan Jing also came with the expert team. They are going to recreate the experiment of communicating gravity at the Basic Science Center of Capital University.
This is part of project settlement.
No matter how detailed the report is, relevant phenomena must be seen in the experiment before it can be determined.
It takes more than a week for Sokai University's physics laboratory to prepare for the experiment.
Capital University Basic Science Center is different.
They have enough equipment and materials. After understanding the entire experimental process, they can start the experiment immediately. Even because the equipment is more advanced, the experimental cost is relatively less.
For example, when it comes to maintaining ultra-low temperatures, their advanced equipment can reduce heat dissipation, making it relatively easy to maintain materials at ultra-low temperatures.
The Basic Science Center only had one morning to prepare, and then conducted the experiment under the guidance of He Yi and others.
During the experiment, they also saw the phenomenon of 'exchange gravity', including the rise of the balloon, changes in the smoke trajectory, and changes in more refined equipment parameters.
etc.
The final calculation result is that gravity has been reduced by 1.7% to 1.8%.
This value is higher than the one in the report, which is also a gain. They can analyze the reasons for the numerical difference in the future, so that they can have a better understanding of the 'AC Gravity Field'.
After it was confirmed that the 'AC Gravity' replica experiment was realized, the expert team from the Department of Mathematical and Physical Sciences, including Capital University's Basic Science Center, and everyone involved in the verification experiment were very surprised by the results.
At the same time, many people also feel very excited.
This may not be a new discovery in international superconducting research, but it is definitely a major discovery in domestic superconducting research, and it may promote the domestic analysis of superconducting mechanisms.
When they were doing experimental and theoretical mechanism demonstration together, He Yi once again talked about the theory they derived.
However, He Yi couldn't explain clearly.
Because he is also chaotic, he only knows the conclusion but not the process.
The expert team from the Department of Mathematical and Physical Sciences, as well as other people who knew the news and participated, are even more eager to meet Wang Hao.
Only Wang Hao can explain this theoretical derivation problem.
But here's the awkward part.
Wang Hao is not a researcher at the Institute of Physics, nor is he a participant in the project. He just went to 'help' and helped with the analysis.
That's all.
The Department of Mathematical and Physical Sciences can manage the project and the laboratories to which the project belongs, but it certainly cannot control Wang Hao.
They had no reason to ask Wang Hao to make a special trip, so they could only call to inquire about the itinerary, and then politely invite him to come and do research together.
Wang Hao received a call and heard about the situation, thinking that he really should go to the capital. His "Outstanding Youth Project" had not yet been settled normally.
In addition, returning to Xihai from Shencheng can be regarded as passing through the capital, so it doesn't matter if you stop by.
His answer was, "I'll go over there after I finish my business in Shen Cheng."
One day, two days...
Many superconducting experts, unable to wait for Wang Hao, simply called the Shencheng Aircraft Design Institute and asked them to "release him" immediately.
When Li Jianhua heard the news, he said that he had made several calls and replied directly, "Professor Wang will not go back until next month!"
"Keep waiting!"
He doesn't care about the Department of Science Foundation Mathematical and Physical Sciences.
Wang Hao received warm hospitality at the Aircraft Design Institute. He would visit the surrounding area every morning, and when he returned, he would walk around the institute and answer questions for others.
It's perfect to live a relaxed life like this every day and occasionally gain inspiration.
He stayed for a week.
The day before he was determined to leave, Wang Hao went to the research institute as normal and answered two questions for others.
Li Jianhua came over angrily and said, "Professor Wang, there is good news about you!"
"what news?"
Li Jianhua came over and said, "For this year's National Science and Technology Award, I just heard that you were nominated for the Natural Science Award, and you are likely to win the first prize."
"This news is not certain yet, but the possibility is very high."
"Yeah?"
Wang Hao didn't feel too surprised. He had been mentally prepared beforehand. When Peng Hui talked about it, he also said that he was likely to win the Natural Science Award for his mathematical research.
The first prize is worth looking forward to.
Li Jianhua noticed that Wang Hao didn't seem to care much and said, "Professor Wang, don't underestimate this award. It really doesn't matter if someone else wins the award, but it's different if you win the award."
Wang Hao became interested, "Why? Is it because you are young?"
"This has nothing to do with your age, because you are studying mathematics, and it is theoretical mathematics." Li Jianhua said, "Since two thousand years ago, no one has won the first prize in mathematics research."
"Before, there were only two mathematicians who won the first prize in natural sciences for their pure mathematical research. You must know their names. One is Hua Luogeng and the other is Chen Jingrun."
"If you win this award, you can be said to be a leader in domestic mathematics in the future!"
Wang Hao was stunned immediately.
He had never carefully studied the First Prize in Natural Sciences, nor did he expect that this award was of such great significance.
Only Hua Luogeng and Chen Jingrun have won the award before.
How famous a mathematician is that?
If he wins this award, he will not only be ranked number one in the domestic mathematics circle, he can also be said to be a cutting-edge leader.
Suddenly, a wave of pressure came over me...
Wang Hao really felt the pressure. He didn't expect that he had reached this level, and he suddenly became a little nervous.
"Would it be difficult to convince the public if I win the prize so early?" He took a deep breath and thought, "It seems that I still need to produce another result before the award ceremony to leave others speechless."
"The new breakthrough in the NS equation should be high-end, right?"
