Hammer of Technology

"Let's wait, didn't you see that the two of you are busy with business?" Lao Ning quickly made a decision.

"No matter how busy you are, you have to eat?! It's almost here, and the food is getting cold without looking at it?" Ning Ma muttered.

"What's the hurry? It'll be hot again when it's cold. This kind of energy is what you need for learning. It's hard to get up the energy once it's vented. When they're hungry, they will naturally want to eat." Lao Ning still Said very firmly.

It was two o'clock in the afternoon after waiting. Seeing that the two children had no intention of eating, Ning's mother finally couldn't bear it anymore and rushed into the room: "Professor Lu, Ning Wei, let's eat first. explain."

"This space sequence... oh, not to mention I forgot, Professor Lu went to eat first, and tasted my mother's handicrafts, it's alright, so what, this is not Yanbei University, there are no steamed buns."

Afraid that Lu Dongyi would say "two buns" again, Ning Wei hurriedly said.

"Oh, eat, yes, yes, eat, thank you, auntie."

"Professor Lu, would you like a drink?"

"Sorry, Uncle, I don't know how to drink."

"It's okay, it's okay, there are drinks at home."

"No, just boiled water will do."

After finishing the meal in a hurry, Ning Wei and Lu Dongyi went back to the room. Lao Ning was left alone at the dining table, drinking a small wine and sipping it slowly.

Ning's mother sat beside Lao Ning, pointed to her son's room, and asked calmly, "Have you seen everything?"

"What did you see?" Lao Ning was stunned and asked back.

"How does your child live in school!" Mother Ning stared at her man and emphasized.

Lao Ning fell silent.

"In the future, don't you meddle in your children's business, do you hear me? I'm telling you seriously, if you want to intervene in everything in the future, I will never end with you. Especially the children's relationship issues, you are not allowed to meddle in the future! Yes Let me tell you anything." Ning Ma said seriously.

"All right, all right, I don't care anymore, and I can't care anymore. As long as he goes to Beijing to study for graduate school or Ph. D., I don't care about his affairs in the future. Just listen to your mother, okay? Hey..." The old man Ning Chang sighed.

It is of course a good thing that the child is older and promising, but after being happy, he feels a little empty.

"You will take out the photo album later, and suddenly want to see the photos of the child when he was a child."

Lao Ning put down his wine glass, sighed and said: "Hey... the child's success is his success, but when you think about it carefully, he is actually still cute when he was a child."

……

Lu Dongyi stayed in Yancheng for five full days, and the harvest was naturally huge.

Although the two of them failed to fully prove the NS equation, and more and more questions were raised, it can definitely be said that the understanding of the NS equation has been further advanced in the mathematical community. Specifically expressed in academic language, the three-dimensional incompressible NS The global existence of equations in a limited space.

More importantly, Wei Ning proposed a new method and mathematical tools to study NS equations.By this method.

Although at present, it is not possible to directly prove the NS equation by these, but it is of great significance to the development of this direction in the field of number theory.Of course, the prerequisite is that these arguments can be recognized by the theoretical circles, or that more and more people can prove that the results of the discussion between Ning Wei and Lu Dongyi are correct.

In fact, Lu Dongyi planned to stay for a few more days, but it happened that the Chinese New Year was coming soon, and Lu Dongyi's parents were also urging him to go home for the New Year. In addition, this issue was almost discussed, so let's continue Maybe there is still something to be gained, but it may not be as big as it was a few days ago, so I can only give up.

However, when sending Lu Dongyi to the station, there is no need to take a taxi. Knowing that the professor from Yanbei University has come to Ning’s house, although Lu Dongyi politely declined the meal, Director Luo arranged for a car to handle Lu Dong Yi was sent to the train station, and Ning Wei naturally followed.

In the car, the two of them could finally discuss a very important question: "Ning Wei, where do you plan to publish the papers discussed in the past two days?"

Ning Wei asked humbly: "Then senior brother, what do you think it's appropriate to post? Or should it be natural?"

Lu Dongyi replied: "Forget it naturally? I don't know why Smith posted that pure number paper on Nature last time. I think that if you want a more professional review, you should choose the four top journals in mathematics." Right. "Annals of Mathematics", "Inventiones Mathematicae", "Acta Mathematica" and "Journal Of The American Mathematical Society" will do."

"Actually, in the direction of partial differential equations, it is quite difficult to publish these four top journals, but your paper will definitely pass the review. There are not many papers in China that can publish papers on these four major journals. From Jianguo to There should be no more than 35 articles now, you should work harder, collect the honors, and then let the teacher help you fight for it, and get the National Outstanding Youth Fund, which will be of great help to your development."

"In addition, after this paper is successfully published, there will definitely be invitations from top academic conferences at that time. You can also take this opportunity to go out and have a look and communicate with the outside world. Although your talent is amazing, this field of number theory Building a car behind closed doors can easily lead to a dead end, and communication is very important. Many professors in the West often have some very unconstrained ideas, although they may not be used, but they can often inspire people."

Lu Dongyi's words were very sincere, and he was really thinking about Ningwei.

Ning Wei nodded, then patted his forehead, and said: "Wait, I remembered, it seems that the editor of "JournalOfTheAmerican Mathematical Society" sent me a paper for review, and I haven't had time to read it yet. "

"Ah……"

Seeing Ning Wei's anxious look, Lu Dongyi smiled and said, "Don't worry, it's okay, it's only been a few days? It's normal for volunteer reviewers to delay for a month or two. For urgent manuscripts, if you do not respond for a period of time, the editor of the journal will take the initiative to send you an email to inquire. The editor has not yet urged, why are you in a hurry?"

"But you are also related to "JournalOfTheAmerican Mathematical Society", why not just send this paper to them."

"Row!"

Ning Wei nodded bluntly. Anyway, to him, there is no difference between the four major journals, and they all belong to the top class in the first district. But soon he thought of another question, looked at Lu Dongyi, and asked: "Brother, How should I fill in this thesis unit? Put our Jiang University and Yanbei University in it?"

After Ning Wei's voice fell, Lu Dongyi smiled even more happily: "What's the trouble with this? You are the first author and you will write about Jiang Daxing. I am already very satisfied if you can give me a second work. After all, I am really not here. "JournalOfTheAmerican Mathematical Society" published a paper."

Ning Wei felt a little embarrassed, and was about to say something, when Lu Dongyi continued: "It's okay, although I haven't published it in "Journal Of The American Mathematical Society", but I have published two articles in "Annals of Mathematics" as one work."

After hearing this, Ning Wei only felt that a trace of embarrassment disappeared.

Well, the sentimental sentence "It is quite difficult to publish these four top journals, and there should be no more than 35 articles from the founding of the People's Republic of China" is not just a compliment to him, but also a boast...

------------

106 People who talk less harshly are the king of the gangsters (four thousand and one more)

After seeing off Lu Dongyi, Ning Wei carefully sorted out his close-up plan in his heart on the car home.

People without thought, he must worry about.

These days at Ningwei's house, after discussing the NS equation, Lu Dongyi did not miss Tian Dao's thoughts.

To sum it up in one sentence, don’t waste a year at Jiangda University, go to Yanbei University as soon as possible. The reason given is also very simple. For mathematicians, most of the achievements are made before the age of 40. .

This is probably why the Fields Medal requires the winners to be under 40 years old.

And what makes many Chinese number theory research scientists sad is that so far there has been no local Fields Medal winner in China.There are actually two people of Chinese origin, one is Academician Qiu who is American, and the other is Tao Shen, who has dual citizenship of Australia and the United States.

At this point, Director Tian placed great hopes on Ning Wei, and naturally he did not want Ning Wei to continue wasting his life at Jiang University.

This is also the place that makes Ning Wei most excited.

If he can really win a Fields Medal on behalf of Huaxia...

Just thinking about it makes him a little excited.

The most high-end Versailles is probably that he doesn't need anything. No matter where he goes, when people introduce him, they have to add, China's first Fields winner, it's quite interesting to think about it.

What is a character design, this is it!

But after careful consideration, Ning Wei still gave up.

If it is purely for fame and fortune, letting go of what he is doing now makes him feel that it is quite boring to be a human being.

Not only the two projects themselves, but also the contract he signed with the laboratory.

Although he believes that Director Tian must have a way to persuade the laboratory to release people, but doing half of the work and pursuing fame and fortune by himself is really not in line with Ning Wei's principles of life.

Regardless of whether Lu Changbin painted big cakes for him before, but in the EDA project, it is indeed asking for money and people for giving. To do chip simulation and output, you need to get a series of parameters of the lithography machine. This Academician Lu is also Help them coordinate Huaxin International, the largest chip company in China, and strive to obtain first-hand data.

It is better to see these things in the eyes.

So it's better to be a year late, anyway, he is only 23 this year, and he still has a lot of youth to squander.

After making up my mind, my heart became much more relaxed, and the next task was simple. I wrote a paper on number theory before the year, submitted it, and went back to school after the new year. I took the time to finish the two projects. He will be able to successfully participate in the postgraduate entrance examination next year, and then go to Yanbei University to continue his studies.

Oh, and there is another very important thing, he still has to complete his first draft review in his life.

Although according to Lu Dongyi's statement, there is no need to rush to review manuscripts. If the journal is really urgent, the editor will take the initiative to urge him, but I think that whether it is "Nature" or "Science", the speed of reviewing manuscripts for him is very fast. It seemed to be quite fast, so he felt embarrassed.

Because he can understand the expectation of submitting a manuscript and hoping to publish it as soon as possible.

So when he got home, he greeted his family, went into his room, turned on the computer, and pulled out the paper from the mailbox.

After reading the title of the paper, Ning Wei probably knew why the journal editors would find him. This is also a paper on the NS equation, and the title is "Complex Flow Numerical Simulation Accuracy and Parallel Computing Based on the NS Equation".

Ning Wei glanced at the author first, um, a university professor teaching in Sweden.

It should be a professor who teaches mathematics.

Because this thesis also belongs to the category of applied mathematics, but Ningwei's epiphany that day and the discussions with Lu Dongyi these days have already deepened his understanding of the NS equation. In three hours, he found several places in the paper that were not quite right.

For example, in the paper, the upwind method is used to solve the NS equation. In order to obtain high accuracy in the calculation of inviscid flux, the original variables on the left and right sides of the grid cell need to be determined by interpolation using the values ​​at the adjacent cells. Then Numerical calculation according to a certain upwind discrete NS equation requires precision.

According to the current theory, the third-order accuracy can only be obtained in one-dimensional flow, while for two-dimensional and three-dimensional flow, the accuracy of the format can only reach the second-order accuracy.

The paper was reviewed very quickly, but after the review, Ning Wei listed in detail the possible problems he thought there might be in the paper, and then gave his final review opinion, which was rejected.

After finishing all this, Ning Wei happily picked up his mobile phone and sent a WeChat message to Lu Dongyi.

"Brother, I just rejected that paper!"

"Oh? So fast? Poor paper quality?"

"I found 4 bugs."

"Little brother is as sincere as I am! In fact, there are many reviewers in the industry who have finished reviewing the manuscript, and they will wait ten days, half a month or even one or two months before giving feedback to the journal editor."

"What is this saying?"

"Doesn't it mean that everyone has no projects on hand recently and seems to be very idle?"

Ning Wei was dumbfounded...

"Ah? Well, what unspoken rules do we have in the academic circle, why don't you explain it to me once, brother."

"How can there be unspoken rules in the academic circle? But brother can teach you a four-character scripture."

"Senior brother, don't be a fool, what four-character scripture."

"People talk less harshly!"

"Give me an example?"

"For example, for a paper that you think is very important, the reviewer gives you a reply to suggest revisions. The revisions mention that you can cite his articles in the paper, and you think that citing these articles will affect yours. Papers, what do you do?"

Ning Wei looked at this content, a little confused.

Then he began to think about whether his journey in the past six months has been too smooth?

He has already published three top magazines, and he has never experienced any of the messy things that the senior brother said.

"Brother, how did you deal with it? Have you revised it?"

"Oh, I was still a PhD student at the time, so I threw the paper and the reviewer's reply to Director Tian. After two weeks, I didn't know what happened. I didn't change it, and the paper passed."

"Brother, I promise, I will go to the postgraduate entrance examination in December next year! I will take the Yanbei Numerology Academy, really! If you don't go, you will be a puppy!"

……

At the end of the communication, Ning Wei quietly figured out the meaning of these four words in his heart for a moment, only to think that the senior brother is actually a wonderful person, every sentence is very interesting, it looks ordinary, but it is a Versailles that has been engraved into it. In his bones, he became an instinctive man.

Dazzle reviewers, dazzle papers, dazzle tutors...

But every time it is not the senior brother who takes the initiative to show off, but just let others bump into his muzzle time and time again, so that he is convinced.

For this kind of subconscious sense of superiority that people despise from the bottom of their hearts, Ning Wei decided to study hard.

Of course he's not available right now.

After discussing the problem, the senior waved his sleeves and left without taking a cloud, but as a junior, he still had to work hard to sort out the thesis.

Oh, and besides that, he will continue to pay attention to the operation of the turbulence algorithm in the laboratory.

Where are you free?

……

This year, Lao Ning's family is full of New Year's flavor.

Of course, Lao Ning and his wife have already made full preparations, and the family has a lot of New Year's goods.

What troubled Ning Wei the most was that after accepting that the Ning family had a great scientist in the future, the relatives from the family and colleagues from his parents suddenly became interested in Ning Wei's other half collectively, without any consideration for Ning Wei. Still a senior student, he began to sell young women around him in various ways.

"Did you talk about a girlfriend at school? Not yet? Auntie has a colleague's daughter who is very nice. She is beautiful and well-behaved. She looks pitiful. Would you like to introduce it to me? It's the Chinese New Year and you can see each other. On the one hand, she was admitted to Beijing Normal University, let’s chat online first, we had a good chat, and when you go to Yanbei University, you will be able to get married.”

There are many similar introductions.

A lot of photos can be retrieved from the phone for Ning Wei to take a look at.

Not to mention, there are quite a few of them who look really beautiful. Of course, then again, youth is the biggest capital of beauty.

Ning Wei really didn't know that these uncles and aunts around him knew so many high-quality girls who were studying in Jiangcheng and Beijing, and even his alumni were among them.

Fortunately, Jiang Da and Yang Xiaohui had such a little ambiguous experience before, which made him much more immune to the topic of having a girlfriend.

Being beautiful is not necessarily suitable, being suitable does not necessarily mean being predestined, and being predestined may not be able to endure him spending time in the laboratory doing projects every day. He used to have no money, but now he has no time, so his girlfriend Ning Wei dare not think about it.

Even because of the inexplicable little relationship with Yang Xiaohui, he didn't dare to meet these girls who seemed to be excellent.

Fortunately, there is still his mother's line of defense, standing firmly on his side, and allowing him to politely decline all introductions.
