The end of technology.

Chapter 83 I can't get it, how hard life is

United States, Princeton.

When Ning Ruo was busy in Shencheng, Robert Kenny once again found a new paper signed by Ning Ruo.

The editor-in-chief of the Annals of Mathematics has actually felt a little numb.

Although Ning Zhi's paper on the NS equation has been up for half a month on the official website of the "Annual of Mathematics", so far there have not been many citations, but this does not mean that the shock caused by this paper is not large.

The actual situation is that Ning Zhi's paper is being widely discussed in the whole academic circle.

At least as far as Robert Kenny knows, scholars in mathematics have been particularly active recently in the field of partial differential equations.It can be seen from the emails and phone calls received by the editors that everyone is very excited.

Another world-class problem has been overcome, which is indeed worth the excitement.

Theoreticians don't care about turbulence algorithms. They are more concerned with whether the proof process itself is rigorous enough, because the scientific community believes that the conclusion is correct, but there are actually many problems that cannot be proved.

Like Goldbach's conjecture.

Any even number greater than 2 can be written as the sum of two prime numbers.Even today with the rapid development of computers, no counter-example has been found, but at the same time, no one in the mathematics community has been able to prove this conjecture through a rigorous proof process.But this does not prevent people from directly citing this conclusion.

But at the same time they could not ignore the practical application of turbulence algorithms.

Just by listening to the algorithm name, you can tell that the algorithm itself is based on the related paper.

So everyone is very excited, but any mathematician with a little reputation will not refute the correctness of this paper without conclusive evidence.The logic chain is very clear. Since the author of the paper can develop a turbulent flow algorithm, it is enough to show the author's depth of research on fluids.

This achievement is admirable.

At the same time, it also eclipsed the first paper published by Ning Zhi in the Annals of Mathematics, the paper on the hyperdimensional cube sensitivity conjecture.

It's like if a person's strengths are too prominent, people tend to ignore his other strengths and weaknesses.For example, Daddy Ma is very rich, and everyone will subconsciously ignore that he is also very bragging.

But after reading Ning Ruo's paper carefully, Robert Kenny's numbness disappeared, and instead he wanted to buy a plane ticket to Huaxia immediately, find Ning Ruo, and then open Ning Ruo's mind to see the structure inside How is it different from ordinary people.

Or start the academic achievement review process to see if there is a large team of mathematicians behind Ningyan.

Three papers, three completely different research directions!

People are working hard in a field, and even if they are writing papers, they are constantly advancing in the same subdivision.But Ning Ruo obviously did not follow this path. He was like a student in high school, where his thesis was written wherever the textbook was.

In his eyes, mathematics seemed to be a whole subject, without those subdivisions.The first article on hyperdimensional cubes, the second article studies turbulence, and the third article switches directly to symplectic topology and Gromov-Witten theory.

What Ning Yu would write in the fourth and fifth chapters, Robert Kenny couldn't imagine.

Is there a math superman in this world?

Really, even if Ning Ruo was solving a worldwide problem related to fluids, such as accurately tracking fluid particles, he would not be so surprised.But this time Ning's paper proposes new mathematical tools for the study of symplectic topology and Gromov-Witten theory.

And from the point of view of the demonstration process, these mathematical tools will greatly simplify the relevant mathematical research.

If he hadn't already learned of Ning's life from Fan Zhenhua, and knew that an ordinary young man in a small town couldn't get top-level academic resources, he would have doubted that this was Chi Guoguo's article signature forgery, or an insult to the editor's IQ forged signature.

Not to mention that people named this set of mathematical tools directly in the paper as Ning's segmentation method.

Writing his name into the textbook is the pursuit of every mathematician. If this is the result of team research, Robert Kenny can't even imagine what kind of person can be selfless enough to give this result to Ning Zhi.

So if you remove all the impossible, what remains is probably the truth.

Just when the infinite emotion rose in Robert Kenny's heart, a sudden movement occurred in his heart, and he thought of a person - Dominic Duncan.

The equally young mathematician is 26 years old and his research happens to include symplectic geometry.

As the editor-in-chief of the Annals of Mathematics, Robert Kearney is very well informed about some information in the mathematics community.

For example, he already knows that the Norwegian mathematician is likely to win next year's Fields Medal for his research on the analysis of relationships between different scales and the establishment of connections between multiple fields of mathematical tools.

This is almost a certainty.

In fact, the academic world is also keen on the creation of gods, especially for the mathematics community, since the Poincaré conjecture was proved, there has been no major breakthrough for a long time.Dominic Duncan's strength is that he is a mathematician with extensive research, whose results are helpful in many areas of research in number theory.

The most important thing is age, 26 years old this year, if nothing else, when he wins the award next June, he will be one year younger than the youngest ever Fields Medal winner, Cyrus Ponte, and will break through. The new record for the youngest Fields Medal can be heartening.

But the real world is always full of coincidences, and every time people thought nothing would happen, the unexpected happened.

Ning Zi's birth, although there is a high probability that it will not affect Dominion Duncan's award next year, but the youngest Fields Medal winner has changed.After all, this Huaxia young man will only be 20 years old next year.

To be honest, Robert Kenney actually didn't want Ning Yu to win the award so early in his heart, and even this represented the aspirations of many people.

Because Ning Ruo is too young.

If Ning Zi wins the Fields Medal next year, the youngest Fields Medal winner will be refreshed to 20 years old, which also means that for a long time, maybe even during the existence of the Fields Medal On this basis, it is almost impossible to continue to break this record.

An excellent gimmick was just tossed away in this way, but after all, this is only the idea of ​​some people.Less gimmicks are obviously more important than the credibility of awards.

The breaking point of thinking of Dominic Duncan is that he and Ning Wei are very likely to win the Fields Medal next year, and they are both winners who have broken the age record of the Fields Medal.

If Dominic Duncan is made the reviewer of Ning Zhi's paper, maybe he will make a good story in the mathematics community.

The confrontation between the geniuses of the century has always been a bridge that people like to see.

If the two have the opportunity to review each other's manuscripts, the opinions given by each other will also become valuable information.

Thinking of this, Robert Kenny directly picked up the phone at the table and called Dominion Duncan. Now the young mathematician is a professor at Harvard. Speaking of which, the two have a good personal relationship. In fact, the "Annual of Mathematics" The editor-in-chief has a good relationship with many great mathematicians.

Of course, this is also due to the occupation. If you have a good relationship with the big mathematicians, you will also be thought of when you submit your manuscript.As for the average mathematician, the situation can be reversed, the call is quickly connected, and Dominette Duncan's voice also comes: "Robert, it seems that you haven't contacted me for a long time."

"Yes, I've been very busy recently, you know."

"Oh... well, what's the matter?"

"There are indeed some things, you should already know that Ning of Huaxia, right?"

This question made the other side silent for a long time, and then he replied: "Of course, the actual situation is that his name has almost made my ears calluse during this time. In fact, I am reading his paper. But if you call, it is also with Like those boring people who want to ask me what I think of him, I might put you on the blacklist. No, not possible, definitely."

Robert Kenny struggled to hold back a laugh.

As expected, there will never be a shortage of people in this world who watch the fun without being too big and like to pick on things. There are quite a few such people, even in academia.

"No, no, Duncan, you should know that I'm not that boring. Of course, if you need a psychological massage, maybe I can recommend it for you... well, it's actually because that Ning submitted another paper, I hope I can You are invited to be a reviewer for this paper."

"He submitted another paper?!!"

The voice on the other side was surprised...

After all, Ning Zhi's paper on the NS equation has only been published for half a month, and this level of results has been produced in the mathematics community. No matter what, it will take a while to revise, waiting for a protracted debate with the academic community, such as every day Reply to various inquiries and discussion emails, accept various invitations to give lectures...

How can it be possible to continue submitting papers?
Of course, this is Dominette Duncan who doesn't know Ning Zhi very well.

Although Ning Ruo received a lot of e-mails wishing to conduct academic discussions with Ning Ruo recently, and there were indeed many invitations, but he had never opened it.Even some of the requests that Fan Zhenhua relayed were decisively rejected by him.

But then again, this dissertation was unplanned.

If it wasn't related to Professor Fang's topic, neither Ning Ruo nor March would have thought of putting together a paper on a mathematical method specifically for a sub-field.

"Well, not only that, but also continued his usual level." Robert Kenny stimulated the other side again.

In a sense, in fact, the editor-in-chief also likes to watch the fun.

Not to mention that the clash of ideas between geniuses is especially exciting.

"But you know, Robert, I haven't done much research on partial differential equations, fluids. Are you sure you want me to be a reviewer?"

"No no no, this new paper he submitted is about symplectic geometry. It is more accurate to say that he has created a whole set of mathematical methods for cutting high-dimensional complex structures, which he calls Ning's segmentation method. I just After reading this paper, if it works, his method can make the process of researching related problems easier and more intuitive."

This introduction once again caused a long silence on the other side of the phone.

"Robert, today is not April Fool's Day."

"I actually thought it was a joke when I just found this paper in the submission system, but I just read the whole article."

"Then... well. Since you recommend it so much, I think you should read the paper first."

"Then pay attention to the mailbox, Duncan, I will send you the invitation link."

"Okay, I'm looking forward to it."

……

Dominit Duncan who hung up the phone opened the mailbox, and after 1 minute, the invitation link had been sent to the mailbox.Click the link, choose to agree, and then enter the paper download page.

Unlike many older professors who prefer to print papers and read paper versions, Dominette prefers to read papers directly on the computer.In fact, it is easier to use a computer than to use pen and paper to mark the places that confuse him or need to be understood.Before formally reviewing the paper, the young math professor's mood was extremely mixed.

If you compare the life experience of Dominette Duncan with that of Ning Yu, you will find that the two have completely different lives.

Dominite was born in Oslo, Norway, the place where the Nobel Peace Prize was awarded. It is also the capital and largest city of Norway, and the Norwegian royal family is also in this city.Its status is roughly equivalent to the capital of China.

His family belongs to the most typical middle-class family in Norway. In fact, for Norway, a wealthy Nordic country, there are actually many middle-class families.Because of extremely high taxes, it is difficult to make people rich, and high taxes bring various social policies with high welfare.

In addition to several Nordic countries are small enough.

The area of ​​Norway as a whole is about the same as that of the provinces in the south of China that are spring-like all the year round. In addition, one-third of the area is within the Arctic Circle. The land is sparsely populated and the population is small. Naturally, various benefits can be directly filled.For example, it can provide lifelong free education for the whole people, as well as high-quality free universal free medical care.

In such a favorable living environment, people often do not have much sense of worry.

But what makes Dominet different from other Norwegians is that he is a gifted struggler.

A comfortable life is not challenging. He likes to compete with others since he was a child, but in the Nordic countries where the body is mostly strong, his physical fitness is very weak.Although he likes almost all competitive sports, these sports have been beaten by peers since elementary school, which is typical of both dishes and love.

This time, Dominette felt depressed, and only felt that life was full of frustrations.

Until he grew up, Dominite was exposed to higher mathematics knowledge and learned that in addition to those competitive sports, there are also intellectual sports in this world, such as the Mathematical Olympiad...

So he finally found his talent, using his IQ to slap the simple-minded guys around him, although for a long time, this didn't make him appear cool among his classmates.But finally found his advantage.

From then on, Dominite began to develop in the direction of mathematicians.

Originally, after graduating from high school, he could apply directly to local universities in Norway, such as the University of Oslo and the Norwegian University of Science and Technology.

But Dominite felt it was too unchallenging to stay in Norway, so he applied to Imperial College in the UK.However, in the days of studying in the UK, he felt that the UK was still not good enough, and the pace of life was not much faster than that of Norway, so he went to Berkeley in the United States after graduating from Imperial College.

Here he finally found the feeling of volume.

First-class universities and high tuition fees, if you don't study hard, you will feel sorry for yourself.

In particular, the management system of "promotion or leave" used by most well-known universities in the United States for professors makes Dominette feel like he has come to heaven.This is using the system to force everyone to roll together.

If you want to rise, you have to have results, and if you want to achieve results, you have to study hard, or you will be thrown into the streets.

Since then, Dominette Duncan has made up his mind to stay in American colleges and universities from lecturer to professor.It turned out that he was already a gifted professor at Harvard at the age of 26, and was nominated for a Fields Medal.Under normal circumstances, as long as he doesn't go crazy and do some messy things, such as blowing up a certain school building, he can basically work at Harvard until he retires.

For a normal person, it would probably only be proud to have such a result at such a young age, but Dominette Duncan is obviously not a normal person.After all, human nature is supposed to be content with pleasure, and there are not many people who can regard scrolling as a hobby.

Yes, in the year leading up to the greatest achievement of his life, Dominette felt nothing but dullness.There are not many people who can accompany him to continue rolling in this industry.It seems that he can only focus on the name of Qing Shi.

In fact, he has been thinking about it a few days ago, and wants to officially start to challenge the problem that ranks first on the Millennium Problem List - the NP-complete problem.

After all, this is one of the most difficult and most important problems in the direction of number theory at this stage.If he can really solve this problem, his mathematical achievements will probably be comparable to Newton's, and he will become one of the most brilliant mathematicians in the 21st century in the eyes of future generations.

Of course, making this decision does need to be prudent. Generally speaking, once this kind of math pit really falls into it, it is not impossible even if there is no result in a lifetime.Especially for someone like Dominette, who is strong in his life, he will definitely not accept this kind of failure willingly.However, before he could make up his mind, Ning Zhi's paper on the NS equation in the Annals of Mathematics made his brain, which already thought he was invincible in the world, a little more sober.

Ning Ruo was too young, less than 20 years old.

This is the biggest blow to Dominion.Even if Ning Zi is more than 30 years old, the Juan Wang will not feel collapsed. After all, as long as he is older than him, theoretically he still has the possibility of catching up.

It's nothing more than achieving similar achievements at the same age... As long as you dare to roll, anything is possible.

But Ning Zi is a full six years younger than him, which means that his 20-year-old will never be able to catch up with Ning Zi's 20-year-old achievements.

Fortunately, after a short period of frustration, Dominite quickly found the direction of his efforts. At the age of 20, he was doomed to fail, so he could only get lifetime achievements.This is also the reason why he has downloaded Ning Zi's thesis even though he has never dabbled in the direction of fluid mechanics.

He wanted to understand Ning Zhi's thinking in solving mathematical problems.

Who would have thought that the next day he received a call from Robert Kenny, inviting him to review Ning Ruo's new paper, which was strongly related to his research direction.

In an instant, his interest was bursting. Is it a young man who excels in many mathematical research directions?

He doesn't believe it!
The thesis must have loopholes!
After all, this world has rules... It is impossible to allow such a powerful person to exist!
……

Ning Ruo didn't know that Robert Kenny helped him find a very special reviewer.

In fact, even if he knew, he wouldn't care.

He is actually different from Dominette Duncan. If there is a choice, he would rather choose a more comfortable life, and definitely would not choose to go crazy and introvert.It's just that God didn't give him this condition.

Dominette probably couldn't feel that feeling at all.

Some people roll to enjoy life, and some people roll just to survive.

It was already ten minutes in the morning, and everyone else had gone to rest. Only he sat silently outside Ding Yulin's room, thinking about his thoughts.

The sudden death of his mother still has an impact on a 19-year-old young man.

As for Ning Zhi, the emotions are more complicated.

He hated Luo Yufang, but never thought that he would face such a problem one day.

Not to mention that he suddenly had a younger sister.

An hour ago, when saying goodbye to Ge Dongshu, he asked this promising president to help him understand Ding Yulin's situation.

Although he is related by blood, Ding Yulin is still too unfamiliar to Ning Ruo, and he is not good at dealing with girls, even if this person is his own sister.This made Ning Zhi feel complicated, even more complicated than solving a math problem.

Half an hour ago, Dad Ning called. After learning about the situation, I hope he can take Ding Yulin to the capital as soon as possible.

But Ning Ruo felt that he should know more before making a decision.

I really can't blame Ning Yu for being cold-blooded, mainly because he doesn't have much confidence in the opposite sex.

There are very few people of the opposite sex who have made him feel warm since childhood, except for his cousin Ning Xiao, there are almost none.For a family, the most important harmony requires the joint efforts of everyone.Now Ning Ruo doesn't care about the material cost, but he cares about the emotional cost.

Most importantly, he didn't want his old father, who hadn't had a few days of happiness, to start trouble again because of an extra sister.

……

Gedongshu maintained high efficiency.

Before Ding Yulin got up, Ning Yu received another WeChat message from Ge Dongshu.

Very direct and intuitive.

There are about a dozen photos, which contain Ding Yulin's test scores from elementary school to junior high school and comments from previous teachers.

I have to say that Ge Dongshu has too many reliable friends.

After all, it's only after seven o'clock in the morning, and it's not time to go to work on weekdays, not to mention that it's already summer vacation.Fortunately, the price had already been paid, so Ning Ruo was able to look at it with peace of mind, and saw his face twitch.

This test result - made Ning Ruo suspicious of the paternity test results that came out in the early morning.

How hard can the final exam questions be?
Especially in junior high school mathematics, there are choices and fill-in-the-blank...

Ning Ruo felt that even if he randomly covered the multiple-choice questions and filled in the blanks with all 1s or 0s, he would definitely get more than 22 points.

Even a pig...

Forget it, sister, dear... He didn't want to scold his own father.

For a moment, Ning Yu even hoped that Shencheng's junior high school mathematics used Olympic test questions, and it had to be all big questions...

Yes, after glancing at the recent transcripts, Ning Ruo regretted asking Ge Dongshu to find these materials.

Fortunately, the teacher's comments are quite satisfactory.

Lively and cheerful personality, able to unite with classmates, willing to help...

As for those suggestions to get rid of the problems of reading villains in class, talking in class, passing notes in class, sleeping in self-study..., they were directly ignored by Ning Wei.These suggestions are of little value. After all, students who can get this kind of score are probably doing everything in class, but it is normal that they will not study.

It was the comments made by the head teacher of the primary school during the summer vacation of the sixth grade, which made Na Ningzhi feel a little emotional.

"Through talking with children and observing their daily performance, it is found that parents have too little company with their children. It is recommended to increase the frequency of children's communication every day, have the courage to express love to children, and give more companionship and care to ensure children's physical and mental well-being. grow healthy."

I dare to write this because I'm about to graduate anyway, so I'm not afraid that parents will complain, or maybe the teacher is about to retire?

Well, even if there are such problems, Ning Yu still thinks that Ding Yulin must have a problem.Because since he was in elementary school, Lao Ning in his family didn't really care about him, and he didn't have much communication and company. After all, Lao Ning had to make money to support his family.

But he has never given up on himself. In fact, because of this, he will be more diligent and self-conscious, because he must do better in order to get more attention and care from the teacher.

So after browsing the contents for a while, Ning Yu put down the phone, and finally had to talk to the little girl in person.

It didn't take him long to wait, almost as soon as he put the phone in his pocket, the door of the room was pushed open, and the little girl rubbed her eyes and walked out. When she saw Ning Ruo sitting on the sofa, she was stunned. There, I forgot to put down the hand that was still rubbing my eyes.

The two looked at each other silently.

About 2 minutes later, Ning Zi finally overcame the psychological barrier and spoke first: "Did you sleep well?"

"Yeah." Ding Yulin nodded.

"Then go wash up first, I'll ask someone to bring breakfast, and then let's chat." Ning Ruo said.

"Oh."

Ding Yulin agreed weakly, while Ning Yu picked up the landline on the table beside him.

……

Ten minutes later, the two sat face to face at the table in the living room of the room, and a breakfast that the waiter just brought to the door was placed in front of them.

Ding Yulin poked aimlessly at the plate with his chopsticks, occasionally raising his head to take a peek at Ning Ruo, and then quickly lowered his head to pick up a bit of food and put it in his mouth.As usual, Ning Ruo was thinking about how to carry out this conversation between the unfamiliar brother and sister while eating.

"I just looked at your transcript..."

As soon as Ning Ruo spoke, Ding Yulin's fair face suddenly turned red, and his head was buried even lower.

After hesitating for a while, Ning Yu adjusted her words: "The grades don't seem to be ideal."

"Um……"

"Why? Don't you like studying?"

"I want to sleep when I read a book, especially a math book." Ding Yulin replied in the subtle voice of a mosquito.

"Oh."

Ning Yu nodded, and then asked, "Have you thought about it in the future? What do you want to do?"

Ding Yulin raised his head, glanced at Ning Ruo blankly, lowered his head quickly, and then shook it.

"But you have to think about it now. I lost my mother when I was six years old. From then on, I would ask myself every day when I woke up, what should I do when my father is old and can't work anymore." Ning Ru calmly stated road.

Ding Yulin's eyes turned red instantly, and the mist filled his eyes...

"Before today, you could be willful, feel that the whole world is sorry for you, or even give up on yourself. Because no matter what, someone will pay for your willfulness. After today, if you still have the same attitude towards life, you will be very happy. Trouble. Because when the world really decides to be sorry for you, you have no room for resistance at all."

When he said this, the darkest moment in his life flashed through Ning Ruo's mind, and the eyes he looked at the girl became sharper.

Ding Yulin lowered his head and continued to remain silent, but tears began to slide down his cheeks, drop by drop, onto the carpet in the room.

Ning Yu continued, "So start thinking about it now, and tell me, what are your plans?"

"I...I...I will study hard in the future, and then after graduation, I will find a job and support myself."

"Are you sure you can study hard?"

"It will...it will."

"Then start from this summer vacation, starting from the basics. I will find a tutor for you. After the summer vacation, my requirement for you is that the results in each subject can at least reach the level of an ordinary first-year student. This is the only thing I can do now. You do. You have to understand the most basic rules of the world, and in order to gain anything, you must first know how to give.”

"I... what if I can't learn?"

"What I ask of you is only what a person with a normal IQ can achieve, and there is no problem of not being able to learn. If you can't meet this standard, then you should think about how sincere your promise just now is. "

Ning Ruo's tone was serious, and his expression was serious.

He doesn't know how to comfort people, and he doesn't know how to deal with this complicated emotional line in front of him, but he just mechanically fulfills the responsibility of a blood brother.

"I don't actually like to talk. I have said a lot for you today. I hope you can take the future into your own hands. Because I have been like this since I was a child. I have experienced some bad things, and I know that kind of The feeling of helplessness. Fortunately, when I was most helpless, my family did not give up on me, but stood behind me unconditionally and marched with me. "

Speaking of this, Ning Yu's tone became more serious and serious: "But the premise of all this is that my efforts from childhood to adulthood have convinced them to believe in me. So they don't ask the reason, they just focus on the spirit. Give me the greatest support and encouragement from material things. Similarly, if you want to get the same support, you must first let me see your dedication, your serious attitude towards life, and your determination to be responsible for yourself.”

Looking at the girl who was sobbing silently, Ning Yu wanted to slow down, but when he said it, he became harder: "Ding Yulin, please remember that this world is never fair, we Just a child of an ordinary family. Even if you want to get as many resources as others, you have to do your best, not to mention your current situation. 13 years old is not a reason to escape, weakness is. But the irony is that the world has never been right Weak people are especially hard."

After speaking, Ning Yu paused, then raised the volume abruptly: "Do you understand?"

The little girl was so frightened by the last sentence that she stopped sobbing: "Ah...get it."

"Okay, finish breakfast now, I need to take a break. Someone will bring your textbooks in about half an hour. During my break, you will read in your room. Next, I will stay in Shencheng to help you deal with what needs to be done here. The funeral is done. Then I will take you to the capital and arrange for you to go to a boarding school, then it's up to you. Dad wants to see you very much, but I haven't agreed yet, I must first see if you have enough for yourself responsibility."

……

Ning Ru stayed in the deep city for three days, and handled everything quickly.

It would have taken longer, but with the help of Ge Dongshu, those big things were quickly completed, and the procedures became less cumbersome.

As for other details, Ning Ruo gave Ge Dongshu full authority to handle it on his behalf.

To Ning Yu's relief, Ding Yulin was not as stubborn as he imagined during the few days of contact.

But after getting off the plane, he still did as he said before, instead of letting Ding Yulin meet the old man at home, he sent him directly to a summer tutoring institution in the capital that Ning Ruo had never heard of.

This offline summer tutoring institution was contacted by Chen Yonggang. According to Lao Chen, the principal of this institution is a former classmate of Lao Chen. Although few outsiders have heard of it, it is full of serious in-service teachers from famous schools. Basically, parents in a small circle send their children there.

According to Chen Yonggang, the principal of the training institution saw Ding Yulin's grades and absolutely refused to accept it. His face was useless, after all, he was afraid of breaking the sign.I still told others that this was Ning Ruo's younger sister, and they reluctantly accepted it.Of course, you have to arrange a special tutor for the little girl.

Chen Yonggang's words probably wanted to express how famous Ning Ruo is now, but obviously Ning Ruo was not happy when he heard it.

Of course, this was also because Chen Yonggang didn't know that Ding Yulin was Ning Ruo's sister, and only thought it was the child of some relative's family. This kind of thing is very common.Ning Ruo didn't make it clear to Chen Yonggang.

It was just about sending Ding Yulin directly to the cram school. Although his younger sister, who was not familiar with him, had no complaints, Lao Ning seemed a little anxious.

When the father and the two sat on the road near the community again, Lao Ning sighed at his son while looking at the photo of Ding Yulin in Ning Ruo's mobile phone.

"Hey...Tell me, what is this called!"

"Good thing."

"Where is it? Where is it! At least bring it back and let me see the baby!"

"It's already spoiled, let you continue to get used to it?"

"When did I say I was getting used to her?"

"I'm still a soft-hearted woman, so I'm not worried."

"I don't worry about you sending me directly to school!"

"Oh, then you're here to help her with her homework? 22 in math, huh..."

Lao Ning suddenly stopped talking.

Can only silently flip back and forth looking at the two photos in the phone.

The son is old and promising, and he can't compete.

For a moment, Lao Ning even felt that his son was too promising... too disobedient.

"Look at this girl, she's so handsome, just like you, with eyes and ears like mine. After a few years, she will definitely be no worse than Ning Xiao, just as rare."

"That also has to have the good character of my cousin. Can Guangjun be a meal? And my cousin has at least passed the college entrance examination."

"Ning Yu, do you have to sing against me today?"

"Just keeping you awake and coddling her will only do her harm."

"Nonsense, I don't know how to educate children better than you?"

"you sure?"

Facing Ning Ruo's clear eyes, Lao Ning was suddenly not so sure.

"Then she can always bring it back for me to see after she finishes the cram school, right?"

"I'll make a decision after seeing how her grades improve."

When Lao Ning heard the words, he handed the phone back to Ning Yu, stood up from the side of the road, patted his butt and said, "I don't care about you, I'm going back."

"Oh, then I'll go back too. By the way, don't ask anyone to find out where she is tutoring, and go see her secretly. I greeted everyone who knew the situation, and I definitely won't tell you. You have inquired, let me know that you go to see her, and I will send her out of the capital."

"you……"

Lao Ning raised his hand, pointed at Ning Yan tremblingly, and put it down after a while: "You send me the girl's photo on WeChat."

"this is okay."

"thank you!"

"Dad, you're welcome."

"go away!"

"it is good!"

……

After soothing Lao Ning's restless heart, Ning Yu finally breathed a sigh of relief in his heart.

He really didn't plan to let Ding Yulin meet Lao Ning until Ding Yulin showed him a complete change in his attitude towards life.

Because Lao Ning really doesn't understand education.

Although he didn't understand, at least he knew that Ding Yulin couldn't continue like this.

At the same time, some people do not know that they are dead...

……

Cambridge, Massachusetts, USA.

While Ning Yu was busy with errands, Dominette Duncan had locked himself in the room for four days.

He reviewed Ning Ru's paper with a critical attitude, but he obviously failed.

In fact, the argumentation process of the paper is very clear, and the steps are very detailed. It is completely opposite to the style of Fermat, the great mathematician. This paper is not afraid of wasting manuscript paper at all, giving Dominette a kind of paper author who treats the reviewer as a reviewer. The feeling of primary school students, many places that can obviously be replaced by obvious ones, still give proofs.

This makes Dominette very unhappy.

After directly researching the paper and unable to find the problem, he began to find another way.

A set of mathematical methods given by Ning Zhi in this paper, as long as he makes mistakes when using this mathematical method to solve related problems, it can naturally prove that this method is not applicable.

After more than ten consecutive hours of work, Dominite was surprised to find that after using Ning Yu's mathematical method, the problems that had troubled him for a long time were indeed much easier.More importantly, using the Ning's segmentation method to prove or calculate, the results obtained for most problems are consistent with the previous results...

And those that are consistent are problems that have been verified by multiple parties.

Inconsistencies are still controversial issues.

The most terrifying thing is that he seems to have solved a problem that has troubled him for a long time by using the method in Ning Zhi's paper, and his mathematical intuition tells him that the solution process is correct!
For a time, a strong sense of frustration drowned Dominite...
