Hammer of Technology

……

"Ning Wei, sit down, don't be nervous. You can think of today as a preview of your graduation thesis defense in advance. But before this special defense, I still have to ask, are you sure you are the one who published the paper on Nature today?" Was it done independently?"

"Yes, Dean Kong."

"it is good!"

Kong Mingde nodded at Ning Wei, then glanced at the professors on both sides and made a gesture of invitation.

The style is very straightforward, of course, because time cannot bear to be wasted now.

……

"Let me ask the first question first, how did you come up with the idea of ​​bringing the theory of quantum fields into the solution of equations?"

"Professor's report starts with the reason why the NS equation has no solution so far. First of all, we all know that the NS equation itself is nonlinear, and the source of the nonlinearity is the second term on the left side of the equation. For nonlinear partial differential equations , except for a few extremely simple equations, the mathematics community has not yet found an effective and universal way to find analytical solutions. In addition, the NS equation itself is a second-order nonlinear equation system, which makes it even more difficult to find a solution."

"Professor Smith's thesis mainly starts from the momentum equation. In mathematics, we generally use the Euclidean description to describe fluid motion. The essence of the control volume analysis under the Euclidean description is still the flow conservation..."

Ning Wei talked eloquently in front of the professors. When it comes to things that cannot be expressed in words, he will also ask for an electronic pen to write the formula directly on the tablet and project it on the big screen in the conference room through a projection.

This kind of defense is very easy for Ning Wei. It is nothing more than reorganizing the knowledge points involved in writing this paper in his brain.

But for professors who are not in the field of PDE research, there will actually be a lot of trouble when it comes to in-depth places.

Although NS equations are more about solving physical problems, mathematics is different from physics after all.

For example, the only meaning of the pressure field in physics is to make the velocity field meet the incompressible condition, but in mathematics, the velocity field needs to be projected into a passive vector space.

The former will need to give boundary conditions, while the latter will analyze the principle of universality.

So when it comes to the depth, not even every professor and researcher at the scene can keep up with Ning Wei's thinking.

Of course, for professors or researchers who study partial differential equations, there is no such trouble.

But this situation can easily turn what should have been a serious defense into an academic discussion.

So after two hours of this special defense, instead of the professor asking a question, rather than answering it, everyone discussed a question from different angles. The formulas for writing and drawing on the projector have been rotated. I don’t know. how many pictures...

In fact, an hour ago, Kong Mingde was able to confirm that the paper on nature was indeed completed by Ning Wei independently.

After all, it is impossible to cheat in the academic defense link.

It is even more surprising that Yu Ningwei has a solid foundation in number theory.

The high-order equations and expansions that need to be used almost do not need to go through the brain. Every time I write a book, I don’t see the slightest hesitation and thinking, and I write it right away without any mistakes.

Is this the level that undergraduates can achieve?

How did this guy keep a low profile in the [-]th grade in his four years of college?

Yau Shing-Tung Mathematics Contest, this great master didn't participate?

CMC actually only won the provincial second prize?

Now that the astonishment has passed, his whole body is numb. There is no doubt that this is a mathematical genius.He even wondered if Ning Wei fell asleep from freshman to junior year...

Did you start working hard in your senior year?

It's numb!

But he is not easy to interrupt the high enthusiasm of the professors, but this time is very embarrassing...

Ning Wei didn't arrive until [-]:[-] for the special defense convened temporarily. Everyone hadn't eaten yet. It's already past [-]:[-] in the evening. If this group of people can continue to discuss, they can probably have breakfast directly.

"Cough cough..."

Finally, after another half an hour passed, Kong Mingde coughed twice as Ningwei finished explaining a question.

"Well, Professor Xu, it's almost done! I think, because of time constraints, this is the end of today's defense?"

"Wait. One last question." Professor Xu glanced at Kong Mingde, very shameless.

"Then... alright." Kong Mingde nodded.

The dean should also respect the outstanding second-level professors of the school and the strong contenders for the next academician selection.

"That Ningwei, I heard that you intend to keep the postgraduate students in this school? Don't bother, why don't you just be my direct doctoral student? The research direction is up to you." Professor Xu said with a straight face.

"Bah...Old Xu, show some face."

"This is a temporary thesis defense, not for you to accept students!"

"Be human! What's the occasion today?"

……

Hearing this shameless question, several professors immediately clamored.

If Ning Wei had only one piece of nature, in fact, even if everyone was happy to see Lie Xin, it would not be like this.

However, the just two-hour defense allowed these professors to see Ning Wei's solid mathematical foundation, quick thinking and rare mathematical accomplishment, which is the most important thing.

Relatively speaking, that piece of nature is no longer the most important. Compared with Ning Wei's performance just now, it's nothing but floating clouds.

He already possessed this ability at the undergraduate level, and the professors present can't imagine what heights he can achieve in the future.

If this kind of child can come to his school, it's really not a matter of posting a few nature articles. Who the hell doesn't want to have an academician of the Academy of Sciences among his students in the future?

When I am old and retired, I meet my old colleagues, take a walk, and suddenly say: "Hey, don't you know? I have a student who has already decided to be an academician, and he is not yet 40 years old. Hehehe, this kid is really lucky. He will come to Jiangcheng to treat me to dinner in a few days, so come together."

Hey, just thinking about it makes me feel so beautiful!

039 Xueshen Is My Roommate

Ning Wei blinked.

When the old professors present quarreled because of him, there was naturally pressure.

What made him even more unexpected was that he had agreed that if he had the opportunity to repay that teacher Xue, he would have a chance.

Of course, the more important thing is that this opportunity was originally intended.

The school guarantees research?

It doesn't exist anymore, some things are missed and missed.

I didn’t have the ability before, but I really have the ability. Who doesn’t want to go to a higher place and see more and more beautiful scenery?

There is no right or wrong, just human nature.

So taking advantage of the time when the professors were all clamoring, Ning Wei met Professor Xu's expectant eyes and said, "Professor Xu, thank you for your kindness, but after Baoyan was rejected because of that incident, I already have I have a new plan. I don’t plan to consider the postgraduate entrance examination for the time being. I hope to take the postgraduate entrance examination normally, and try what kind of university can be admitted to graduate school with my own level.”

"What kind of thing are you talking about?"

"The teacher of the research and admissions office said that he lost my paper application materials and forgot to notify me, so he didn't help me apply for the insurance research."

"Bang! What happened to the Graduate School? The Research Admissions Office can lose the student's application materials? Such an irresponsible person is sent to the Graduate Admissions Office?"

"Ahem, okay, okay, everyone, don't be impatient. Let's get here first today. Let's discuss other things slowly."

Kong Mingde said with quite a headache.

Everyone understands.

This kid obviously wants to use the professors as gunmen to vent his personal anger, but now the professors are absolutely willing to be guns, one is willing to fight, the other is willing to suffer, who can he reason with?

But then again, the research and recruitment office really went too far this time.

Lost your student application materials?

Which brainless reason came up with this!

……

At the same time, the school's general library, on the third floor.

Luo Xiang and Xu Ruixuan were studying quietly with the four girls in the fellowship dormitory.

Of course, if reading comics can also be counted as self-study.

In fact, it's still a bit suffocating.

Recently, Xu Ruixuan wants to open a topic on Zhihu, called "What is it like to have a girlfriend who is dedicated to taking the postgraduate entrance examination."

too difficult!

If you want to invite someone to have a supper together, you must first spend at least three hours reading in the library.

I dare not complain.

Xu Mo's eyes widened, he looked fierce and fierce, so cute, he was afraid that he would not be able to control it.

Don't ask Mr. Xuan, who has always been fearless, why he is so cowardly now, it's because Xi Shi is in the eye of the beholder, and the cruel theory of evolution.

It is said that the straight man gene who dares to fight with the opposite sex without any pretense at the beginning of a relationship will eventually be gradually eliminated by nature.

The rest will be coated with a layer of protective color on the surface of the straight male gene, and the camouflage will fade away when it is obtained.

Luo Xiang and Mr. Xuan probably belong to this kind. The popular saying is a sheep in wolf's clothing, just like the book in front of them, with a cover for the postgraduate entrance examination and politics, but inside it is the passionate Fu Ren. pass.

Occupying the precious resources in the self-study room of the general plan, feeling the coolness brought by the comfortable central air-conditioning, but doing things that have nothing to do with studying, the two of them have no shame at all.After all, being able to keep quiet has already proved their quality as students of China's double first-class universities.

However, several tables next to them began to whisper with their mobile phones, and even the voices became louder and louder, making the four girls who had really entered the state of study and buried themselves in their studies raise their heads.

Xu Mo muttered dissatisfiedly: "What's the situation? The study room in the library is always very quiet."

"That's right, if these people have any sense of public morality, I'll ask!"

Mr. Xuan immediately put down Fu Renzhuan, which was about to burn in his hand, and answered the sentence angrily, then stood up, and quickly moved to the table about two tables away, where the chatter was the most lively, and patted the table with the classmates beside him excitedly. The brother said something on the shoulder, and asked, "Hey, brother, how old are you? Do you still understand some rules? What's the noise in the study room? Do you have any kindness?"

"Oh, I'm sorry, just now I saw a message from the instructor in the class group, and I was a little excited. A senior student in our major sent an article on nature, which was published today and is still in the first edition. Our Jiang University The Shuyuan is really too powerful!"

Mr. Xuan blinked and said, "Wait, what major did you say you were in?"

"Numbers!"

"Senior senior brother from the Nursing Academy posted nature? Who posted it? What's the name?"

"Wait, let me take a look, um, it's called Ningwei."

"F*ck!" Mr. Xuan couldn't hold back, and roared, in exchange for countless rollicking eyes...

"I'm sorry, I'm sorry, I'm excited, I'm excited..." Mr. Xuan waved his hands around, a small scene, for a senior student, as long as the teacher is not around, everything is a small scene.

Then he lowered his head and said to his junior, "What a coincidence, the senior student brother you're talking about happens to be my roommate? Which class are you in?"

"Ah? Sophomore base class!"

"Sophomore base class? Then we are in the same building as us. Tell your classmates that if you want to pay homage to worship and take a photo with the God of Learning, you can come to our room 302. Ten yuan a time. I think you are pleasing to the eye. Your classmates come You can get a [-]% discount if you give me the name of Mr. Xuan! Remember it!"

After finishing speaking, Xu Ruixuan ignored the stunned eyes of the elementary school boy, and jumped back to his seat, and was greeted by Xu Mo's cold question: "What did you just say stupidly?"

"It's a big deal! The SCI article that our baby Ning talked about was posted on Nature, and it's the first edition! A bunch of elementary school students are discussing our baby Ning!"

"Ah? What are you talking about? Nature? The nature in England? Fuck, no wonder the professor from Imperial College came to Ning Wei and gave him an interview opportunity. This kid Ning Wei is awesome!"

When Luo Xiang was sighing, several girls had already quickly taken out their mobile phones.

It is super fast to log in to the library system with the library's WIFI.

Soon the new issue of nature has been found, and then opened, you don't need to look for the first edition, just click to open...

"It's really Ningwei's paper, pure English? No second author? Xu Ruixuan, didn't you say last time that Ningwei is better at math and English is as good as you?"

Xu Ruixuan spread his hands, met the four curious eyes with surprise, and said, "I'm sorry, I made an empirical mistake. Ning Wei's English was really as good as mine when I was a sophomore and junior. We The grades of Level [-] and Level [-] are similar, who would have thought that Ning Baobao will be like a different person when he reaches senior year, there is nothing I can do about it!"

"I?" Xu Mo glared at Mr. Xuan.

"Wrong, it's your little Xuanzi."

Luo Xiang smiled foolishly.

"What are you laughing at? What self-study are you still doing? Hurry up and go back to the dormitory to help Ningwei celebrate! Damn, the SCI has been posted on nature, and the god of learning is in your dormitory and you don't know how to go back to worship the great god, you guys Are you two stupid?!" Lu Jiajia scolded sharply.

"By the way, Xiaohui, do you think so?"

Yang Xiaohui looked at the phone, as if she had never heard of it.

040 Be a human being, don't be too careless

Luo Xiang and Mr. Xuan were driven back to the dormitory by the girls, and then found that the dormitory was crowded.

Before the tickets were collected, the dormitory was already full of senior students, and Ning Wei didn't seem to have returned, because a group of people were gathering around Liu Cong to listen to stories, or to listen to this guy bragging.
