Wang Hao arrived at the Shencheng Aircraft Design and Research Institute at 9 o'clock in the morning, and the official start of the lecture was planned to be 10 o'clock, and the time was still relatively tight.

He exchanged pleasantries with everyone, and then went to the back to make preparations.

The lectures were 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 problems reported by the lecture.

Last time I was at Xihai University, Wang Hao explained very seriously, but Li Jianhua, Zhao Xin and others couldn't understand it.

Li Jianhua was deeply impressed by this, and he said to Wang Hao euphemistically, "Professor Wang, can you talk more about it this time?" That's ...... way of yours."

"It's too difficult!"

Because he knew the importance of the content, he didn't want to lose face, so he said that he wanted Wang Hao to speak in more detail.

"Don't worry, I'll go into more detail." Wang Hao said.

Li Jianhua looked left and right, but didn't see Wang Hao take out anything, and asked a little strangely, "Are you prepared?" ”

"What preparation?"

"For example, some materials and the like...... Li Jianhua was a little worried, because he didn't see any information or anything like that, he thought that Wang Hao had no preparations.

Wang Hao pointed to his head and smiled confidently, "It's all here." ”

Before coming, Wang Hao also thought about preparing some materials, but later found that it was not necessary at all.

The system of equations given by Cui Xunnian is enough for him to practice, and he has completed six sets of approximate solutions in a row, and in the process of continuous replacement and transformation, it can be said that the use of the new method is pure.

This method was still researched by himself, and everything was already imprinted in his mind.

In addition, he just explained how to use it, so that others knew how to use it, so naturally there was no need to prepare for it, everything was already clear.

However, Wang Hao thought about it and planned to have time to write a summary, analyze the underlying logic of the entire derivation, and even if it is not published, it can be submitted to a confidential study for sealing.

This may be useful for other people's research.

After all, there is no guarantee that his research will not be surpassed by future generations, and it is even said that there will definitely be future generations who will be able to surpass it, or improve the methods he has researched.

If there is no relevant derivation content at all, and the method of solving is only taught, it is equivalent to the application of technology without theoretical basis, and there is no room for improvement.

Wang Hao thought about it and said, "Mr. Li, you don't have to worry, I estimate that this lecture will take at least six hours." ”

"Six hours?" This length of time surprised Li Jianhua very much, he thought it was just a lecture of one or two hours, and he didn't even make sure that there was content in the afternoon.

Wang Hao said, "Six hours may not be enough", he said very seriously, "although it is unlikely, but I hope that everyone can understand." ”

It was just a simple sentence, but Li Jianhua was very moved, he didn't expect Wang Hao to attach so much importance to the lecture.

Some scholars are invited to give lectures, and in the course of the lectures, they don't care whether the people below can understand or not, and even say that they feel that the people below can't understand, which proves their erudition even more.

It's not just one or two scholars, it's a lot of scholars.

For example, in some academic exchange report meetings, some experts come up to make reports, and they don't care how many people can understand them.

As long as the top experts can understand and make a judgment.

Wang Hao would rather speak for a while longer, Li Jianhua was really moved, and he found that Wang Hao sincerely hoped that more people could understand, not just say it verbally.

In fact, of course, Wang Hao will attach importance to the lecture, so that more people can understand, so that more inspiration and knowledge can be given back in order to be in

New breakthroughs have been made in the study of the S equation.

Of course, at the same time, he does want more people to understand.

After all, it is my own research, and spreading it to more people can be regarded as a personal achievement.

……

Soon, the lecture began.

This report is attended by a number of scholars.

Wang Hao stood on the podium of the conference hall, looking at the crowd below, it felt a bit like a big classroom in the school, and it was roughly estimated that there were more than 100 people.

More than 100 people may not seem like much, 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, some people are here to join in the fun.

In Wang Hao's eyes, Li Jianhua belongs to the type of fun, because Li Jianhua is doing the overall design of the aircraft and leading the team to do aircraft design projects, rather than specializing in aerodynamics research.

In the field of aerodynamics, his level is at most higher than that of ordinary doctors, and he may not even catch up with ordinary doctors, but he knows more about applied research, and his foundation must be quite lacking.

There were many scholars in the audience who were in a similar situation.

They may be experts in a certain direction, but as long as they are not engaged in fluid mechanics or aerodynamics, or they do not specialize in the study and use of relevant equations, it is almost impossible to understand the report.

There is a specialization in the art industry.

This is especially true in the field of science and mathematics.

Even if it is a top academician, it is difficult to involve cross-field content, even non-major research fields, and the level of ability to catch up with a doctoral student 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 to give a lecture here. ”

"This is a study report on the direction of my solution to 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 the NS equation and partial differential equations."

"Mr. Li thinks that my research is very helpful for the calculation of aircraft shape design, so I am standing here."

"I don't think you're here to listen to polite words, so let's go straight to the topic."

After Wang Hao finished speaking, he wrote two lines on the whiteboard, that is, two titles - "Finding the Approximate Solution of the System of Partial Differential Equations" and "Comparative Analysis and Correction of the Replacement Equation and the Original Equation".

"I split the research into two parts. The previous method of finding the approximate solution of the system of partial differential equations will be explained in the morning, this part of the content is relatively simple, I believe that most people can understand and understand. ”

"The latter topic, the comparative analysis and correction of the substitution equation and the original equation, will be explained in the afternoon, which is relatively difficult, but it is also the most important part of the calculation."

"Let's start with the first part."

“……”

Wang Hao began to speak seriously, he was like a teaching class, he behaved very casually, but the explanation was very fine.

The audience also listened attentively.

They found that Wang Hao's speech was very slow, and it was only an introduction to the calculation method, which was indeed easy to understand.

However, some people still find some areas obscure, and they can only write them down with a pen and write down their conclusions before they can continue to listen to them.

There are also some that I don't understand long after I start.

Among them is Li Jianhua.

Listening to the explanation again this time, Li Jian knew why he couldn't understand it, because he didn't have a relevant mathematical foundation, or in other words, he had forgotten it a long time ago.

In the absence of 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 a certain amount of research and understanding in aerodynamics, but when he encountered a very professional and complex problem, even if the other party explained it in detail, he couldn't even understand it.

There are also some people who can't keep up quickly, but the reason why they can't keep up is not that they can't understand it, but that they are a little distracted in the process of listening to the lecture, or they say something to others, and then they can't keep up at all.

They couldn't help but whisper to the others, "How did you get here?" What were you talking about? How did that conversion come about? ”

No one answered.

Many people have found that the content of Wang Hao's explanation is very difficult, but they can still understand it if they listen carefully.

It's not the same if you get distracted.

That's what math is all about.

In a whole logical system, there is one step that cannot be followed, and it will be difficult to understand later, but the lecture on the stage will certainly not stop, nor will it be explained by a single person.

Wang Hao explained seriously on the stage.

He hopes that everyone can keep up, there are some difficult things to understand, and he has emphasized it several times in a row, but there are still some people who can't keep up, so there is no good way.

He could only keep emphasizing, "If you don't understand what you just heard, write down the conclusion and treat it as a definition or a formula." ”

After saying that, I continued.

The whole process was like a lecture to the students in the classroom, but no one cared about it at all, they didn't have time to think about other issues, they just listened carefully.

However, on the whole, just like Wang Hao's judgment, the content of the morning is still relatively simple.

Even if you don't understand something, you can write down the conclusion and follow along.

……

Midday.

Wang Hao was taken to lunch, and then went to the lounge to sleep.

He did feel a little tired, because he was catching the plane in the early morning, and he came directly to the lecture after coming.

I slept for nearly two hours.

When I woke up and stretched, I recovered a little, and at half past two, I was in the conference hall again.

A lot of people are already waiting there.

"The content in the afternoon is the comparative analysis and correction of the replacement equation and the original equation, which is more difficult than in the morning."

Wang Hao's first sentence gave everyone a preventive shot, "It involves some difficult mathematical analysis methods in discrete mathematics and functional analysis." ”

"If any of you don't have a foundation, you can jot down the conclusions without trying to understand the whole thing."

This part is the most difficult, and Wang Hao doesn't even think that anyone will be able to understand it all.

He already has an understanding of the level and ability of the experts in the audience.

These experts are engaged in the study of aerodynamics, but most of it is applied rather than theoretical. They also have little research on other partial differential equations, let alone some advanced analytical methods.

There are certainly some highly qualified experts among them, but most of them have not touched so many fields.

In addition, some experts are already old, and they can't consume so much content in one go, and even if they have the foundation, it's difficult to keep up with it all.

So it's a good idea to memorize some conclusions and try to understand them, rather than wasting a lot of energy on difficult things.

After Wang Hao finished the previous words, he began to speak seriously.

Because the content involved is more difficult, the explanation is more detailed than in the morning.

The audience listened very carefully, and some of them just joined in the fun to listen, but after knowing the content, it became clear that they had to master this method.

The content of Wang Hao's lecture is directly related to aircraft design, and the relevant calculations are not a problem after mastering this method.

At the same time, they understand the value of content.

At first, when they heard that 500,000 people were invited to give lectures, they thought they were wronged, but after knowing the content, they felt that it was impossible to buy this method, let alone 500,000, millions, or tens of millions.

This is directly related to the shape of the aircraft.

The more accurate the calculations are, the more flexible and capable aircraft can be designed.

If you could improve the performance of each aircraft a little bit, how much value would it create?

At present, the manufacturing cost of a top-notch fifth-generation aircraft is calculated in units of '100 million'. Even if it's just a little bit of performance, the value created can be said to be massive.

When everyone is very serious, Wang Hao is also more motivated to explain, and at the same time, he also finds that the inspiration value of the research task of the NS equation is constantly increasing.

It 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 needs to be graphed to analyze."

"We don't need to shape the function in particular, but we try to make the graph as smooth as possible."

"Smoothness here does not refer to the smoothness of the solution set, but to ensure that the solution is ...... around this curve"

“……”

The further Wang Hao's method goes, the more difficult it becomes, and the slower and slower his explanation becomes, and each step takes a long time.

At this time, Li Jianhua also understood why Wang Hao said that it would take at least six hours, and the content behind it was too difficult, especially when it involved mathematical analysis.

It's just calculation, comparison, and analysis, not to mention many steps, and each step also involves a very deep mathematical analysis method.

He couldn't understand it for a long time, just looking at the complex columns and graphics on the whiteboard, his head was already big.

Finally.

The four-and-a-half-hour lecture was over.

After Wang Hao finished the last sentence, his voice was a little hoarse.

He hurriedly poured a sip of water and said with a wry smile, "Ask, just wait for tomorrow to come back, I really can't hold on today." ”

"I changed the plane in the early morning, and I'm too tired now."

"But it doesn't matter, I'm going to stay in the provincial capital for three days, if anyone has any questions, they can come and ask me tomorrow or the day after tomorrow."

……

End of report.

Wang Hao went to the hotel to rest as soon as possible, and waited until noon the next day to feel recovered.

"500,000, it's really hard to earn!" He got up with emotion, and after lunch, he was invited to the Aircraft Research Institute.

There are a lot of people who are already waiting.

Now it is time to continue the questions of yesterday's explanation report, and he patiently answered everyone's questions, as if completing a job, but in the process of explaining, there is also gain.

[Task 1, inspiration +1.] 】

[Task 1, inspiration +1.] 】

Looking at the continuous increase in inspiration value, Wang Hao also felt full of motivation, and even wanted to stay for a few more days.

At the same time.

The expert group of the Department of Mathematics, Physical Sciences returned to the capital.

He Yi, Xiao Xinyu and Yan Jing also came with the expert group, and they wanted to recreate the experiment of exchanging gravity at the Basic Science Center of Capital University.

This is part of the project settlement.

No matter how elaborate the report is, it is necessary to see the relevant phenomena in the experiment to be able to determine it.

The physics laboratory at Seohai University took more than a week to prepare for the experiment.

The Center for Basic Sciences at Capital University is different.

They have enough equipment and materials, and after understanding the whole experimental process, they can start the experiment immediately, and 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 much easier to maintain ultra-low temperatures of materials.

The Basic Science Center only prepared for one morning, and then conducted experiments under the guidance of He Yi and others.

During the experiment, they also saw the phenomenon of 'alternating gravity', including the rise of the balloon, the change in the trajectory of the smoke, and also the change in the parameters of the finer equipment.

Wait a minute.

The final estimate is that gravity is reduced by 1.7 to 1.8 percent.

This is a bit higher than the report, and it is also a reward, and they can analyze the reasons for the discrepancies, so that they can better understand the 'communication gravity field'.

When the experiment was confirmed, the experts from the Department of Mathematical and Physical Sciences, including the Basic Science Center of Capital University, and all those involved in the verification experiment, were very surprised by the results.

At the same time, many people are feeling very excited.

This may not be a new discovery in international superconductivity research, but it is definitely a great discovery in domestic superconductivity research, which may promote the analysis of superconductivity mechanism in China.

When they were doing experimental theory mechanism demonstration, He Yi talked about the theory they deduced again.

However, He Yi couldn't say it clearly.

Because he is also chaotic, he just knows the conclusion and doesn't know the process.

The expert group of the Department of Mathematical and Physical Sciences, including other people who knew the news and participated, hoped to meet Wang Hao even more.

This problem of theoretical derivation can only be explained by Wang Hao.

But herein lies the awkwardness.

Wang Hao is not a researcher at the Institute of Physics, nor is he a participant in the project, he just went over to 'help' and helped to do the analysis.

That's all.

The Department of Mathematics, Physics and Sciences can manage the project and the laboratory to which the project belongs, but it certainly can't manage Wang Hao.

They didn't have a reason to let Wang Hao come on a special trip, so they could only call to ask about the itinerary, and then politely invite him to do research together.

Wang Hao received a phone call and listened to the situation, thinking that he should really go to the capital, and his 'outstanding youth project' has not yet been settled normally.

In addition, returning to Xihai from Shencheng can be regarded as passing through the capital, and it is nothing to pass by the way.

His reply was, "When you're done with Shen Cheng's affairs, I'll go over." ”

One day, two days......

Many experts in superconductivity couldn't wait for Wang Hao for a long time, so they simply called the Shencheng Aircraft Design and Research Institute and asked them to hurry up and 'release them'.

When Li Jianhua heard the news, he said that there were several calls over there, and he replied directly, "Professor Wang won't go back until next month!" ”

"Keep waiting!"

He didn't care what science fund mathematics and physical sciences department had.

Wang Hao was warmly welcomed in the aircraft design institute, and he toured the surrounding area every morning, and when he came back, he went around the institute to answer other people's questions.

It's perfect to live such a relaxed life every day and occasionally get inspiration.

He stayed for a week.

The day before he decided to leave, Wang Hao still went to the research institute normally and answered two questions for others.

Li Jianhua came over in a hurry and said, "Professor Wang, there is good news related to you!" ”

"What's the news?"

Li Jianhua walked over and said, "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." ”

"It's uncertain yet, but it's highly likely."

"Really?"

Wang Hao didn't feel too surprised, he had a certain amount of mental preparation before, and 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 still worth looking forward to.

Li Jianhua found that Wang Hao didn't seem to care much, and said, "Professor Wang, don't underestimate this award, if other people win the award, it's really nothing, but you win the award differently." ”

Wang Hao became interested, "Why?" Is it young? ”

"It doesn't matter how old you are, because you're studying mathematics, and it's theoretical mathematics." Li Jianhua said, "Since 2,000 years ago, no mathematical research has won the first prize. ”

"Before, there were only two mathematicians who won the first prize in natural sciences with pure mathematical research, and you must know the name, 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 China in the future!"

Wang Hao was stunned for a moment.

He really hadn't studied the first prize in natural sciences in detail, nor did he expect this award to be so significant.

Only Hua Luogeng and Chen Jingrun have won awards before.

How famous is that?

If he wins this award, he will be the most cutting-edge leader in the domestic mathematics circle, not to mention the first in the domestic mathematics circle.

Suddenly, a wave of pressure came to his face......

Wang Hao did feel the pressure, he didn't expect that he had reached this level, and he suddenly became a little nervous.

"Will it be difficult for me to win the award so early?" He took a deep breath and thought, "It seems that there is still another result before the award ceremony, so that others will be speechless." ”

"The new breakthrough of the NS equation should be high-grade, right?"

“……”
