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 was 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, and he said to Wang Hao tactfully, "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 saw nothing Wang Hao had taken out. He asked strangely, "Are you prepared?"
"What preparation?"
"For example, some information..." Li Jianhua was a little worried. Because he didn't see any information, 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.
The set of equations Cui Xunnian gave him 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.
He had researched this method himself, and everything was already imprinted in his mind.
In addition, he just explained 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 for other people's research.
After all, there is no guarantee that his research will not 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, "Designer Li, don't worry. I estimate that this lecture will take at least six hours."
"Six hours?" Li Jianhua was very surprised by this length of time. 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 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, there are many scholars like this.
For example, at some academic exchange conferences, some experts go up to give reports and do not care how many people can understand them.
As long as top experts can understand it and make a judgment, that's all.
Wang Hao preferred to speak for a while longer. 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 when more people can understand them can they give back more inspiration and knowledge so that they can learn more in the future.
A new breakthrough was made in the research of s equation.
Of course, at the same time, he does hope that more people will understand.
After all, it is my 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 the audience is full of top scholars, 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 a lot of shortcomings 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 are not involved in fluid mechanics, aerodynamics, or specialize in studying and using related 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 don't have any 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, so let's get straight to the point."
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, which will be explained 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 speak 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 he only introduced calculation methods, which 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 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 complex 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 math is like.
In a whole set of 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 things that were difficult to understand, and he emphasized them several times in succession, but there were still some people who 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 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 lectures 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 were 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 everything."
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 so many fields.
In addition, some experts are already old, and they cannot consume so much content at 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 not only 500,000 yuan, but also millions or tens of millions would be enough to buy people with this method. possible.
This is directly related to the appearance design of the aircraft.
If the relevant calculations are made more accurately, a more flexible and better-performing aircraft can be designed.
If the performance of each aircraft can be improved, how much value will it create?
Nowadays, the manufacturing cost of a top-notch fifth-generation aircraft is calculated in units of '100 million'. Even if it only improves the performance a little bit, 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 understood it, and his head was already spinning just by looking at the complex formulas and graphics on the whiteboard.
finally.
The four-and-a-half-hour lecture is over.
After Wang Hao said the last sentence, his voice became 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 to feel recovered.
"Half a million, it's so 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 were going to re-enact the gravity exchange experiment 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 'communicating gravity', including the rise of the balloon, changes in the smoke trajectory, and changes in finer 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 later analyze the reasons for the numerical difference, so that they can better understand the 'AC Gravity Field'.
After it was confirmed that the experiment to replicate the 'AC Gravity' was achieved, 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, including other people who knew the news and participated, are even more hopeful to see 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 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 won't go back until next month!"
"Keep waiting!"
He doesn't care about the Department of Science Foundation Mathematics 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 before. 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 study mathematics, and it is theoretical mathematics." Li Jianhua said, "Since two thousand years ago, no mathematics research has won the first prize."
"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 mathematics in the country 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 had 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 hit me...
Wang Hao did feel the pressure. He didn't expect that he had reached this level, and he suddenly became a little nervous.
"Would it be difficult for me to convince the public if I win the award 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?"
"..."
