Wang Hao's work is too busy.

As soon as he put down Liu Rongxing's phone and said a few words to Zhang Zhiqiang, there was a knock on the door of the director's office.

"Knock, knock!"

Liu Jian, director of the finance department, was standing at the door.

"Director Liu, please come in!" Wang Hao raised his head and hurriedly said.

"You may be seated."

Liu Jian didn't have time to sit down at all, so he walked over and asked directly, "Professor Wang, the Wuhan Iron and Steel Research Institute has just sent eight million to the school's account, saying that it is a horizontal project

Do you know this? 「

He was a little confused.

This feeling is that there is no preparation, and suddenly Wuhan Iron and Steel Group called 8 million, just called and said that it was a horizontal fund for Wang Hao.

Horizontal funding?

For Wang Hao alone?

This is beyond Liu Jian's understanding. He had been working in finance at the school for so long, and it was the first time he had seen a horizontal project for one person, and the amount of funding was high

Eight million RMB.

Liu Jian didn't understand it after thinking about it, because there was no communication before, and the money suddenly arrived in the account, just like paying a salary.

involved such a large amount of money, he hurried over to find Wang Hao.

Zhang Zhiqiang was stunned next to him, he had just digested the information of 500,000 yuan of questions, and it quickly became 8 million?

Both of them looked at Wang Hao together.

Wang Hao nodded and said, "It's a project with the Wuhan Iron and Steel Research Institute, but it's not actually a project, but they asked me to do an analysis, and I will help analyze it." That one

If there is a problem, just stay under the school account first, and then go to the finances if you use it. 「

"Good, good~~"

Wang Hao stared at Liu Jian sloppily, and he still felt very shocked outside his heart.

The horizontal expenditure of 4 million is also an abnormal number, but it is not understandable for projects aimed at individuals.

―Individual, what can you do?

I was sure that there was no problem, so I could only leave with doubts.

Liu Rongxing kept staring at Liu Jian and asked, "Liu Jian, - personal project, four million?" Can he do that project on his own? 「

"If you want to help?"

I don't have the heart to compare now, the gap between the comparisons is too small, so small that there is no way to envy and envy.

― I may be jealous of a colleague who is paid less than my own, but I am definitely jealous of the chairman of the company.

The two sides are at the same level.

Liu Jian smiled and said, "Brother Zhang, it's slow, you originally planned to do that project together, and it's not a little difficult for you yourself."

"But the county distribution, you still have to study it sloppily.

"Okay, you'll wait."

Liu Rongxing listened to the beauty in his heart, and he couldn't help but have no expectations.

Four million!

Even if you only give 1% to yourself, it's a lot of money.

Liu Jian did not slow down the project of Wuhan Iron and Steel Research Institute, and the simple analysis of a small amount of experimental data can be completed in a time.

I still looked at what Zheng Guofeng sent first.

Zheng Guofeng sent a file containing a small number of simple calculations and functions.

There is no explanation of what it is outside the document, but it is explained in a mathematical way, which is to ask whether it can achieve the correction of the curve of the function with the help of instantaneous force.

"That's not a problem, is it?"

Liu Jian read it carefully and knew that the problem was very simple.

The outside is talking about the correction of eight-dimensional functions, and it also involves the knowledge of fluid mechanics and conventional physics

Makes the path close to the transformed curve trajectory.

"That correction relies on an instantaneous burst of force, or a short-term continuous change, but the ultimate goal is a regression curve correction."

"The difficulty lies in the calculation, the function that has not changed the orbit has to be corrected to the original function trajectory, and it is an eight-dimensional function......

"It's very difficult!"

"That's 700,000, it's really easy to take!"

Although the other party just wants to know whether it can be realized, but if they want to determine whether it can be realized, they still need to go back to a certain analysis to answer.

Analysis, not the easiest.

"It's a function to correct the trajectory, what is it for?" Liu Jian frowned slightly and thought about it sloppily, his thinking was connected to Zheng Guofeng, to aerospace and rockets, and then to associate practice

There is no answer.

Space flight?

Rocket?

Missile!

Mistakenly, it's ballistic missiles!

Now there are two kinds of missiles, one is a cruise missile and the other is a ballistic missile, and the difference between the two missiles is under power.

The cruise missile is equipped with an aero engine to take off, change orbit, and cruise as if it were an airplane; And ballistic missiles are like rockets, not on fuel

Move to operate.

Cruise missiles are relatively less flexible, but because they have to be loaded with aero engines, there is very little difference in whether they are in terms of strike range or load.

A ballistic missile is equivalent to a warhead on a rocket, and the minimum strike range can exceed 10,000 square meters, and the disadvantage is not that it is flexible enough.

Therefore, the orbit change of ballistic missiles has always been a very important research and development direction.

"So, it's probably not a missile trajectory change?"

Liu Jian thought about it and suddenly didn't worry a little, but he simply shook his head, "What's the matter with me, anyway, you're just doing mathematical research."

"That's just a math problem, what the county body uses to do is relevant to you, and the NS equation will also be applied to fighter jets and submarines."

"Very little scientific research will be used in related fields, and there is no way to do it."

I'll just keep researching.

Very slowly, Liu Jian found that he had a way to give an answer for a while, because it involved content that was beyond his ability.

It's true that I'm not a top mathematician, but mathematics is not very classified.

Liu Jian is good at the field of number theory, including analytic number theory and probability number theory, and the other is not the content of mathematical analysis, functional analysis and discrete

I am very proficient in learning.

It's not a partial differential equation at the top.

Now the content of the document involves advanced function theory and computational mathematics, I have not dabbled in function theory and computational mathematics, but to say that I am proficient in it is definitely talking

Lower.

In those two directions, I don't have top-level results, and I just apply some relevant methods under my own research.

At the same time.

Space Agency Headquarters: Outside an office in a small building, Wu Yanfeng and a middle-aged man in military uniform were talking face-to-face.

The middle-aged man is Zhang Zhiqiang, a professor at the First National Defense Primary School and a well-known expert on rocket ballistics.

Zhang Zhiqiang is saying, "Now you are talking about that problem, which mainly involves future research and development and change the direction."

"In terms of missile orbit change, in fact, there is no mobile gliding technology, but our country is also developing that kind of technology, and it is difficult to say that the county body is not less effective."

"The main thing is that it's hard for your missiles not to have a chance to be tested, and once they are actually tested, you know that they won't be effective."

"So, you still want to work out new ways to change orbits, such as instantaneous burst thrust, or unilateral thrust."

"There have been very few arguments in that regard, but there are no conclusive conclusions."

Zheng Guofeng shook his head as he spoke.

Zheng Guofeng said, "Professor Zheng, he is also worried, you recommend Liu Jian to him, if there is no problem, I am not the first in domestic mathematics, or even world mathematics, Qi."

Do you dare to say that you are weaker than me? 「

Zhang Zhiqiang was still a little worried, "Liu Jian is good at number theory and differential equations, are you sure I can do it?"

"If there's a problem."

Zheng Guofeng patted his chest and said, "You know Professor Wang too well, as long as it is a mathematical problem, I can solve it for the scriptures!"

"What's more, you are asking me to give a solution, just to give my judgment and opinion on that problem."

"That's right!"

Zheng Guofeng listened and nodded, "You still doubt Professor Wang's mathematical level, you can complete the Goldbach conjecture, if they are all such super geniuses, aren't they...

I said with a wry smile, "Professor Wang's fee is really low."

"There's a way." Zheng Guofeng said, "It's not a level, it's not a price, 700,000 sounds like a lot, do you know, many institutions are rushing to let Liu throat."

Past. 「

"That's right, too."

Zhang Zhiqiang nodded approvingly, some top scholars are indeed worth that price.

Sure Liu Jian can give a definite answer, the "consulting fee" of 700,000 yuan is really cheap, and we can take more detours and go straight to the goal.

I am sure that Liu Jian knows that Zheng Guofeng is so unconfident in himself, and he may be moved to a sober up, because I do have the ability to give i to the questions in the document at the level of the future

Definite answer.

But I'm still looking at the problem, regressing sloppy research.

Liu Jian felt that 700,000 yuan was too much, but in order to receive the "order", it was necessary to satisfy the "customer".

Customer, not the emperor!

Only if you don't establish a good problem-solving persona, you can receive fewer orders.

Make money, for the sake of the economy.

It wasn't long before I researched it, I simply set up a mission.

【Task 8】

[Project Title: Trajectory Correction of Eight-Dimensional Functions (Difficulty: A).] 】

[Inspiration value: 0.] 】

"Difficulty A? It's okay—" Liu Jian exhaled heavily.

The difficulty of solving that problem lies in the fact that my research on function theory and computational mathematics is far more advanced.

It's definitely S-level difficulty, and it's too easy to complete, and the maximum estimate is that it will take less than a few months.

It's just a level A difficulty, which is relatively difficult.

Liu Jian thought about it and simply found some information.

It was also an opportunity for me to improve myself.

Since then, I have been engaged in research on number theory and partial differential equations, but now I am expanding the field, hoping to expand in function theory and computational mathematics.

This requires a small amount of knowledge to be supplemented with a deeper understanding of the underlying regression.

How?

Tuition!

Liu Jian's two courses, "Complex Analysis" and "Nonlinear Functional Analysis", are obviously related to function theory and computational mathematics.

I thought about it and decided to give my graduate students a class.

"Yes! Just do that! 「

"The little \ family learns to regress together..."

"You should also give fewer lectures to your students!"

Wu Yan thinks about it sloppily and thinks it doesn't make sense, the way I am a tutor has always been to answer questions about students' regression, but I don't take the initiative to talk about anything.

It's also a good practice to talk about something often, even if the content is related to the main direction, so it's good for students to dabble in less knowledge.

When I do research, I also deal with functional theory and computational mathematics.

The sub-disciplines of mathematics are all interrelated, and even when doing the study of number theory and partial differential equations, there are no other methods that will involve other content, especially functions

methods are used very rarely.

Before I thought about it, I found Xu Chao and asked me to inform the others that every day at half-past seventeen o'clock at noon, or in the morning, I would take time to hold a big class and talk about some things

West.

Before Xu Chao heard this, His Majesty immediately informed the others.

It's slow, and no one knows anything about the Mason Number Lab.

Liu Jian originally only planned to give lectures to his mathematics graduate students, but by noon, very few students from the laboratory had come, including a few professors downstairs,

Associate Professor and Ph.D. Tusheng.

That also caused the large conference room to be packed.

Of course, the number of people in the class is still small, but the total number of people is more than 80.

Wu Yan tugged at the corners of his mouth, and first reminded him generally, "You are just giving a lecture to your students, and the things you talk about include some basic content, and they want to listen to it."

I can come and listen to it, but I guess it doesn't help much. 「

"You just hope that the students will learn less about the knowledge and methods of other directions."

Qi Xiaoma helped the student to express his position, "Professor Wang, let him speak, you can listen to the scriptures."

"Yes, let's talk about it!"

"It's okay to talk about the most basic knowledge, you hate listening to your lectures the most, you talk less than others, and it's very difficult to understand and remember."

Faced with such a cold attitude of professors and students, Liu Jian could only be forced to speak.

The first thing I am talking about is indeed the basic content, a basic summary of the regression of the real variable function, and the previous plan is a retreat for the knowledge of single complex variable functions and less complex variable functions

― a summary of the system.

In the process of explanation, on the one hand, students can deepen the scope of knowledge, and on the other hand, they can improve their understanding of knowledge.

That's a win-win situation!

The explanations of the first class are all systematic summaries, because most of the lectures are doctoral students, even graduate students are very poor, and there is very little knowledge we know.

It's just a one-time pass.

Therefore, the pace of Liu Jian's lectures is very slow.

Even so, the students felt that they had gained a lot, and we felt that we had a deeper understanding of the content of the function direction.

For a week, Liu Jian insisted on giving lectures to the students every day, and I would choose a time that conflicted with the curriculum.

It's either noon or morning, and often regresses in the afternoon.

The time is fixed.

On weekends, there are two major hours of lectures every day.

The main content of my explanation is function theory, from the very end of the foundation, fast and regressive, and when I go deeper, the speed of the explanation will be faster.

In that process, Liu Jian also felt that his knowledge had not been accumulated, and his understanding of the basics was deepened.

At the same time, I also feel that it is not good for me to give a lecture once a lot.

Mathematics contains so little content that the relevant sub-disciplines can say more than a dozen, more than seventy, and the anomaly - the individual may be involved in all the content.

The same is true for Liu Jian.

Now I plan to use the lectures to continue my in-depth understanding and research in function theory and computational mathematics.

Meanwhile.

Newly created quests are also broken to gain inspiration points.

【Task 8】

[Inspiration value: 59.] 】

"It's slow!"

Liu Jian spent two weeks, and the inspiration value is not yet halfway.

That value shows that the foundation is not enough, and solving the problem still requires sloppy research, and before there is no small direction, the inspiration value can be slowly increased.

The main research idea, I have thought about it, is not to connect the functions of the county body through the calculation of a series of equations.

The calculation of partial differential equations is what I am good at.

"First of all, substitute the values to do the calculations."

"If you can definitely solve a problem, it means that there is no problem in that direction."

"Surely the problem is too simple, and there is a way to judge it through conventional calculations, and if that direction is fine."

Wu Yan pondered, and suddenly realized a key question, "That's right!"

"Although you are studying the possibility of realizing the problem..."

"However, it seems that it is just an answer to whether it can be achieved, and maybe a solution?"

"The ......"

"You should charge less, right?"
