The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 168, Substitute Teaching, Preparing for the Harbin Institute of Technology Mathematics Journal

July 20, 1980, Harbin Institute of Technology, Handheld Game Console Project Office.

Wang Duoyu, who had just finished lunch, walked in and asked Yin Wenjie, Zhang Jikang and others to come over and report on the project progress.

In the morning, he was still teaching in the lecture hall to a group of gifted students from universities across the country, but Duan Dongming and his colleagues actually wanted him to help review their papers.

Of course Wang Duoyu refused without hesitation.

Can these students afford to compensate him for wasting his meal time?
It's too much!

Anyway, Wang Duoyu ignored these students. Isn’t it easy for him to review their papers?

You can just submit your paper directly to journals such as "Science China Mathematics". Why do you have to show off in front of him?
His time is not meant to be wasted like this. Don't think that Wang Duoyu will show leniency to these students just because they have "paid tuition fees". He is just thinking too much.

In the office, after listening to the work reports of Yin Wenjie and Zhang Jikang, Wang Duoyu nodded calmly, and then urged them to hurry up and move forward. If they had any questions, they could come to him at any time.

In the coming August, Wang Duoyu will probably stay in Harbin Institute of Technology and not go anywhere else.

In the blink of an eye, it was August 1st, Army Day. Lin Dehong personally came over to invite Wang Duoyu to participate in the event.

The latter declined.

He has no time in the morning, he has plans in the afternoon, and he has classes in the evening.

Anyway, his schedule this August is very tight.

On August 3rd, Wang Duoyu finally finished writing the novel, um, "The Final Chapter of Snow City".

This is the last one, and the Snow City series will be completely finished from now on. There will be no prequels or sequels.

"Duoyu, are you free today?"

The next day, Liu Deben went to see Wang Duoyu. After hearing that the latter said he was temporarily free, he immediately said:

"The 45th Institute of the Ministry of Mechanical and Electrical Engineering has invited you to lead a team to visit them to discuss the photolithography technology research and development project."

Wang Duoyu heard this and immediately shook his head:

"President, I can't leave. You know I have classes every day. Peking University and other schools have already said that they have to go back to school in September this summer. They definitely can't stay at Harbin Institute of Technology anymore."

"Why don't you ask the comrades from the 4th and 5th Institutes of the Ministry of Mechanical and Electrical Engineering to come to us? We have lithography machines here anyway. This project is very important, so they must come as well."

Upon hearing this, Liu Deben was silent for a while and then nodded to indicate that he would give it a try.

People from the Department of Mechanical and Electrical Engineering, don't be too proud.

No one can say whether they are willing to come to Ice City.

After watching Liu Deben leave, Wang Duoyu lowered his head to look at the work at hand: the proof paper of Fermat's conjecture!
Yes, he just started this work today. I guess Qiu Chengtong has already started it for half a month, right?
Of course, if Wang Duoyu wants to prove Fermat's conjecture, he has to start with the Taniyama-Shimura conjecture.

This conjecture is related to the Fermat conjecture: if the Fermat equation has any solution (a, b, c) for exponent p > 2, then it can be shown that the semistable elliptic curve y^2 = x(xa^p)(x+b^p) will have unusual properties such that it is unlikely to be modular.

Therefore, proving the Taniyama-Shimura conjecture for the case of semistable elliptic curves may prove Fermat's Last Theorem.

In the following period, Wang Duoyu began research in this area.

Everything went very smoothly at the beginning, but a week later, one night, he actually forgot to go to class. It was not until Yang Xiuhua appeared in the office to urge him that Wang Duoyu realized that he had not even had dinner.

"Professor Wang, I heard that you've been proving Fermat's Last Theorem recently, is that correct?"

After the class was over, Yang Nianzhen quickly walked up to Wang Duoyu who was about to leave the classroom and asked curiously.

The latter ignored the other party's idea, but Yang Nianzhen asked if there was any way she could help.
Wang Duoyu then stopped, looked at the other party for a few seconds, and said:
"Can you help me with my lessons? Tomorrow's lesson is the first three pages of the Poincaré Conjecture paper in three dimensions. No, that's not right."

Before he could finish his words, Wang Duoyu left.

Yang Nianzhen was stunned. How could she possibly help Wang Duoyu with his lessons?

She herself doesn't quite understand the Poincare conjecture. She came here to study, not to teach. If she had such ability, why would it be like this?
However, Wang Duoyu had already arrived at the office and found Xue Xiaoling.

He planned to ask the latter to substitute for tomorrow's class.

When Xue Xiaoling heard this, she was immediately panicked.

Let her come to class?
If it was a basic course, then of course she would have no problem, but this was Wang Duoyu's class, and it was a paper on the three-dimensional Poincaré conjecture. How was this possible?
Seeing that Xue Xiaoling refused, Wang Duoyu immediately called Rong Guangxia and Mo Ruogao to ask for their opinions.

After hearing this, the two were also confused.

In the end, Mo Ruogao took on this important task because he used to be a math teacher and had some teaching ability and the ability to perform well on the spot.

Of course, Mo Ruogao also made a request, that is, Wang Duoyu could sit in the classroom when he was teaching.

Of course Wang Duoyu had no objection. As long as he could find time to write the thesis, there would be no problem.

So the next day, in the lecture hall, when Mo Ruogao stood on the podium, Yang Nianzhen, Duan Dongming, Ding Haiyang and others were stunned.

Oh my goodness, isn't Mo Ruogao the HIT student who published his paper in the Annals of Mathematics? I heard he and Wang Duoyu used to live in the same dorm?
Is it okay to let Mo Ruogao take over Wang Duoyu's class now?
Even if Wang Duoyu is sitting in the classroom, he can always step forward to help if there is anything outside of class.

However, everyone still has great doubts.

Liu Deben and the others had heard about this, but since it was handled by Wang Duoyu himself, there was nothing they could do.

Regardless of whether it works or not, Mo Ruogao has already stood on the podium, while Wang Duoyu has already entered the state of writing the thesis proof and automatically blocked out external signals.

Others may not be very clear about it, but Wang Duoyu knows very well that proving the Taniyama-Shimura conjecture will involve many technical details, so he must be extremely cautious.

If you are not careful, accidents are likely to happen.

These technical details include prerequisite knowledge such as elliptic curves, modular forms, and Galois representations. Wang Duoyu will need to create more relevant theories or mathematical tools in the future, and then perform calculations one by one to connect the entire building.

At present, Wang Duoyu has reached the stage of verifying the mathematical tool of modularity improvement theorem.

Wang Duoyu wrote on the manuscript paper:

"For the elliptic curve E, we first have to prove that if the Galois representation p(E, p) modulo p is irreducible and modular, then so is this."

Just this one sentence, followed by a lot of verification. Just these verifications alone, if it were someone else, it would take at least a week or more than ten days to figure it out.

But Wang Duoyu only needs a few minutes.

When the brain is operating at high speed, it is equivalent to an extremely sophisticated supercomputer, and the results after calculation and processing must be correct.

"What the hell are these symbols? Why the hell can't I understand them?"

Chen Yanhui, a Chinese university student sitting in the front row next to Wang Duoyu, was completely dumbfounded.

Several other students also didn't understand, and when they looked at the blackboard again, they were confused again.

Because Mo Ruogao had already said a lot at this time, they didn't hear some of the content, and then they couldn't keep up with his thoughts in an instant.

Good heavens, Wang Duoyu sitting next to them didn't allow them to try their luck at all, but instead disturbed everyone's thinking and made them distracted.

Fortunately, the substitute teaching was only for one day, otherwise, it would definitely be more troublesome later.

Wang Duoyu is busy attending classes, writing papers, and also has to find time to follow up on the handheld game console project. He is indeed very busy.

There is no way around it.

In other words, the handheld game console project is not progressing that fast, and many aspects are still in the theoretical stage.

For example, there is still no sign of the photolithography machine.

A few days later, delegations from the 45th Institute of the Ministry of Mechanical and Electronic Engineering and the 109th Factory of the Chinese Academy of Sciences came to Harbin Institute of Technology, and Wang Duoyu had to suspend the proof of his thesis.

The arrival of the two major departments made Liu Deben and others very happy.

However, when the negotiations began, the demands put forward by the 45th Institute of the Ministry of Mechanical and Electrical Engineering almost made Liu Deben lose his temper on the spot.

What the hell!
The 45th Institute of the Ministry of Mechanical and Electronic Engineering and the 109th Factory of the Chinese Academy of Sciences both hope that Harbin Institute of Technology will invest all the R&D funds, while they will only provide manpower, and the R&D results will be divided equally among the three parties.

Damn it, how can you do that?

He starts bullying people right away and has no sincerity at all.

Wang Duoyu was not angry, but he could hear that the 45th Institute of the Ministry of Mechanical and Electronic Engineering and the 109th Factory of the Chinese Academy of Sciences were eyeing the funds of Harbin Institute of Technology.

Thanks to the Diao Pai Company, Harbin Institute of Technology now has relatively sufficient funds and is also a guest of honor of the Foreign Exchange Department.

Unfortunately, the two units of the Ministry of Mechanical and Electrical Engineering were "abandoned" by their leaders because too much R&D funds were taken away from foreign countries and they had no outstanding achievements.

In fact, if Harbin Institute of Technology had not set an example and exported so many batteries abroad, the 45th Institute of the Ministry of Machinery and Electronics and the 109th Factory of the Chinese Academy of Sciences would not have been so miserable.

After all, in this era, everyone is engaged in "imitation". Technology is sufficient for domestic use, and leading the world is unthinkable.

Harbin Institute of Technology Diaopai Company has achieved unparalleled global technological leadership, and naturally has become the object of envy and jealousy of major research institutes.

Therefore, after confirming Harbin Institute of Technology's current cooperation idea, the 45th Institute of the Ministry of Mechanical and Electrical Engineering and the 109th Factory of the Chinese Academy of Sciences hit it off: to get more scientific research funding!
Otherwise, they would have no rice to eat.

They provide the manpower and HIT provides the money. So, it is not impossible for them to take a bigger share of the scientific research results.

But more than 60% will be taken directly, and 33% will be given to Harbin Institute of Technology. Moreover, Harbin Institute of Technology will not lack manpower, and will even provide technical guidance.

So it is definitely wrong for the Ministry of Mechanical and Electrical Engineering to ask for such an exorbitant amount of money.

"No, this definitely won't work!"

Liu Deben was furious, panting like a cow, and flatly rejected it:

"Director Tang, Harbin Institute of Technology has contributed both funding and manpower, and will also provide technical guidance. Therefore, the scientific research results of this lithography machine R&D project cannot be distributed in this way."

At this moment, Wang Duoyu suddenly said:

"Director Tang, Director Yan, if Harbin Institute of Technology recruits a technical R&D team from each of your two companies to work for Harbin Institute of Technology, how much funding would you need?"

Take the fire out of the cauldron!

As soon as he opened his mouth, the meeting room fell into freezing point.

Liu Deben laughed when he heard this. He was not annoyed at all because Wang Duoyu interrupted him. On the contrary, he felt relieved.

Tang Yumin, director of the 45th Institute of the Ministry of Mechanical and Electronic Engineering, frowned and rejected Wang Duoyu's proposal without hesitation.

However, Director Yan Ruoxin of the Chinese Academy of Sciences' No. 109 Factory asked curiously:
"Professor Wang, if we agree, how much funding can Harbin Institute of Technology provide? 500,000 or 1 million?"

"Director Yan, aren't you asking for too much?"

Wang Duoyu said this with a smile, and Liu Deben immediately nodded in agreement.

The subsequent bargaining work was followed up by Liu Deben.

Well, the research and development project of the lithography machine is not that simple. Xue Yuheng, Li Kangmin and Yao Wenrong had already started to organize the information for this part at the end of June, and they had also gone to the 4th and 5th Institutes of the Ministry of Mechanical and Electrical Engineering for study and internship.

But if they rely solely on these people, it may take Harbin Institute of Technology a very long time to develop the lithography machine they want.

But if we hire researchers from the Chinese Academy of Sciences and the Ministry of Machinery and Electronics to help, it would be very different.

If Harbin Institute of Technology recruits a group of technical personnel and also allows its students to participate, the lithography machine project can be developed quickly.

The stepper lithography machine is currently the world's leading lithography machine technology, and Wang Duoyu was thinking of the stepper and repeater lithography machine technology that has theoretical guidance but has not yet been realized in the United States.

This thing can reduce the magnification. In the 1980s when the technology iteration of integrated circuit size was constantly shrinking, this technology was undoubtedly the real mainstream.

If Wang Duoyu wants to realize such lithography technology, he will of course need a large number of technical talents to help him achieve it.

If you buy it directly from abroad, haha, it is indeed too expensive and not conducive to subsequent development.

We are not the Polar Bear Empire, which has already given up and laid down, and the Polar Bear Empire's electron tube technology is still very advanced.

Therefore, steadily advancing transistor technology, developing more advanced lithography machine technology, and improving integrated circuit technology are what we should do.

Relying on imported lithography technology from abroad will definitely not work.

It's like now, not only do you have to purchase lithography machines at a price of $450,000 per unit, but you also have to wait in line.

By the time GCA company produced it, the daylily was already out of fashion.

It is better to rely on yourself than others!

For the next half day, when Liu Deben had almost finished bargaining, Wang Duoyu finally came up with a set of theoretical guidance.

"Step-and-repeat lithography is primarily used for processes larger than 0.25 microns. Director Yan, I'd like to briefly explain the theory behind this technology: during lithography, the mask remains stationary while the wafer is stepped to perform all the exposure work."

There's actually another technology, the stepper-scan lithography machine. This technology offers advantages in exposure field of view and uniformity, reducing the need for stepper-scan lithography in manufacturing below 0.25 microns.
These are all very good technical theories, but it is not so easy to implement them.

Seeing that Wang Duoyu had such a thorough grasp of the process technology of the lithography machine, Tang Yumin, Yan Ruoxin and others were all shocked.

The next day, new negotiations continued, but unlike the arrogance of yesterday, this time, Tang Yumin and his team were indeed very sincere.

After more than two hours of negotiations, more work on finalizing project details continued in the afternoon. It was not until dusk that the lithography machine research and development project was finally finalized.

This project will be hosted by Harbin Institute of Technology, and will be jointly developed by the 45th Institute of the Ministry of Mechanical and Electrical Engineering and the 109th Factory of the Chinese Academy of Sciences.

The initial funding for the project is RMB 10 million, and an additional RMB 20 million will be invested in the future, depending on the specific situation.

Harbin Institute of Technology will build a new research institute in the Ice City for the subsequent research and development and improvement of related technologies.

In terms of scientific research results, of course, Harbin Institute of Technology will get 50%, and the remaining 50% will be distributed between the two units of the Ministry of Mechanical and Electrical Engineering.

After the finalization, the project officially started.

At the same time, Harbin Institute of Technology started recruiting people immediately after finalizing the stepper re-lithography machine project.

More scientific research talents must join in, otherwise, even if this project is completed, Harbin Institute of Technology will still be in trouble.

After the project was finalized, Wang Duoyu could finally return to his previous life.

In the blink of an eye, it was the end of August.

Wang Duoyu has almost finished writing his proof paper.

It took him nearly a month to improve the mathematical tool of modularity and prove that all semistable elliptic curves are modular.

For him, this time is still very long.

Although it may seem from the outside that he is not focusing all his energy on proving his thesis this month, in fact, he is.

Because whether he is teaching Yang Nianzhen and others or doing other work, he doesn't need to spend much energy, it's just a waste of his time.

On the contrary, the proof of this paper was the project that really consumed a lot of his time and energy.

The end of August passed in the blink of an eye, and September is here soon.

At this time, the class was coming to an end. Wang Duoyu was cramming Yang Nianzhen and his group of students, and it was almost time to review the results.

Wang Duoyu didn't care about all that. He finished the course in a hurry, turned around and rushed into the office to continue his thesis research.

When the last word was written, Wang Duoyu finally breathed a sigh of relief.

When Wang Duoyu walked out of the office, he saw Yang Nianzhen, Duan Dongming, Chen Yanhui and others. He was in a good mood and couldn't help but ask curiously:

"Why are you still here? Aren't you supposed to be back in school?"

"No, we're not going back, Professor Wang. Didn't you hear what we said before? We're not going back to school for now. We're going to stay at Harbin Institute of Technology for another month."

Yang Nianzhen and the others immediately explained, and Wang Duoyu nodded in surprise.

It seems to be true, but he didn't pay attention to it at the time and ignored it.

Chen Yanhui now mustered up the courage to ask:

"Professor Wang, have you proved Fermat's conjecture?" When these words came out, everyone's eyes widened. Yang Nianzhen and others even exclaimed in surprise, and then covered their mouths.

Everyone knows very well what a top mathematical problem Fermat's conjecture is.

In July, Yang Nianzhen also went to Princeton University with Wang Duoyu. At that time, in the auditorium, she heard with her own ears that the latter made a bet with Shing-Tung Yau to see who could complete the proof of Fermat's conjecture faster.

Unexpectedly, it now seems that Wang Duoyu completed the task first.

"No way! You're overthinking it!"

Wang Duoyu shook his head and denied it.

Although he has completed it, it is just a smokescreen and he will definitely not let the outside world know.

Even if Shing-Tung Yau had completed the proof first, he would not have submitted the paper so quickly. Besides, how could Yau have completed it in such a short time?
In the past three hundred years of history, there have been countless top mathematicians, but no one has been able to prove Fermat's conjecture.

Although Shing-Tung Yau is very talented, it is absolutely impossible for him to accomplish it in such a short time.

Because Wang Duoyu is not worried about this matter at all, he can take it slow.

The reason why he had to finish his thesis first was because he needed to deal with other things.

You know, he has a lot of projects on hand now. Just the handheld game console project includes step-and-repeat lithography projects, chip design and development projects, handheld game console battery projects, LCD design and development projects, and "China Cube" game cartridge projects.

"Okay, I won't chat with you anymore, just go and do your own things."

After saying that, Wang Duoyu turned and left.

But Yang Nianzhen and others behind him didn't quite believe it.

After all, before today, Wang Duoyu had always felt like he was being chased by a ghost, and his daily schedule was very tight.

Only today is it so leisurely.

At the end of August, everyone felt that he would occasionally smile during class, which definitely meant that he had made a breakthrough in his thesis.

In the next week, Wang Duoyu will organize and copy the paper, and then plan to spend another half a month translating it into English. After finishing it, he will put it away and publish it later.

On September 9, Wang Duoyu found Wu Congxin and asked him about the current preparations for the Harbin Institute of Technology Mathematics Journal.

Previously, Wu Congxin, Liu Taoshun and others went to Princeton University to attend a lecture, and to exchange and learn advanced experiences and learning methods from abroad.

One of them is studying magazines such as the Annals of Mathematics.

"Professor Wang, our preparations are pretty good. There are no problems with printing or translation, but the problem lies in the quality of the papers. We spent two or three months collecting papers, and except for Xue Xiaoling and Rong Guangxia's papers, the others are not acceptable."

When Wu Congqin heard this, he immediately complained bitterly!
If the quality of the paper is not high, then it is unlikely that the outside world will order it.

Wang Duoyu frowned immediately. He wanted to publish his paper first in the magazine of Harbin Institute of Technology to make a breakthrough. However, he was afraid that there would be no other papers to follow up. The goal was too high and others would not be able to follow up. What should he do?

Because a magazine cannot have only one author like Wang Duoyu.

But at present, there are only so many top mathematicians in the entire Harbin Institute of Technology, and even in the whole of China, and there are even fewer young mathematicians who can produce high-quality papers.

Su Buqing of the Acta Mathematica Sinica took the initiative to invite Wang Duoyu to contribute articles, and the same was true for many magazines such as Science China Mathematics. Isn't the reason they did this because they didn't have enough high-quality papers?

"Director Wu, let's continue with the preparations. We can start with the royalties. Harbin Institute of Technology still has sufficient funding, so we can pay the authors a slightly higher price, but the quality must not be compromised."

After a moment's silence, Wang Duoyu said:

"On the other hand, the price of our magazines can be lower. We strive to expand the influence of our magazines, but we absolutely cannot distribute them for free. This is absolutely not allowed!"

Wu Congqin nodded in agreement.

Then he seemed to suddenly think of something, looked at Wang Duoyu and asked curiously:

"By the way, you've been working on proving Fermat's conjecture lately. Have you finished your paper? Or have you achieved any scientific research results?"

Wang Duoyu just smiled and said that they still needed to wait.

After discussing this matter, Wang Duoyu didn't talk about it anymore.

The preparation work for the "HIT Mathematical Journal" can only be done slowly. Wu Congxin and his team will first complete the preliminary review, and then the review team they formed will conduct the second round of review.

It will then be handed over to Wang Duoyu for final review.

With Wang Duoyu's current status, there is absolutely no problem for him to complete the final review.

It can even improve the professionalism of the magazine.

It’s just that Harbin Institute of Technology currently does not have an extra top mathematician, otherwise cross-review would be better.

As soon as he walked out of the office, Wang Duoyu saw a security officer who handed him a letter.

When I opened it, wow, it was Liu Xiaoli again.

What does she want to do?
But this time it was not the old place, but Liu Xiaoli's complaints.

There was a lot to do, mainly because after he finished writing "The Final Chapter of Snow City" and sent it out in early August, "Beijing Literature and Art" soon began serializing it.

At the same time, the novel has been typeset and printed in preparation for publication.

But because of this, we received more letters from readers than ever before.

Liu Xiaoli wrote to say that she went to Beijing last week to help him collect the letters from readers. She has opened many letters so far, and there are a total of 4,800 yuan in rewards from readers.

Then he asked Wang Duoyu what to do with the money?

What to do?

I can only save it for now, and I can’t invest it in buying a house, nor can I use it for anything else.

Things like buying antiques for investment or lending them to others for business are not advisable.

So the only thing to do is to keep it.

It’s like the 50,000 US dollars that Wang Duoyu brought back from the United States, which has not been touched until now.

After reading the letter, Wang Duoyu returned to his desk and wrote back to the other party, taking out a thousand yuan and telling her to do with the money as she pleased, to spend it or do anything else with it, and to save the rest.

After he finished writing the letter, he thought of Zhu Ling, whom he hadn't seen for a long time, so he went to find Liu Deben and prepared to go to Beijing in two days.

The latter would certainly comply with every request, but he needed to arrange things here, after all, there were too many things to do in the handheld game console project.

Two days later, Wang Duoyu arrived at Yanjiagang Airport and set off for Beijing.

He makes a lot of money, but he spends it quickly.

If it was a business trip, the airfare could of course be reimbursed, but like now, he must have paid for it himself, so naturally he could not take advantage of the school.

After arriving in Beijing, Wang Duoyu went to the vegetable market to buy an old hen and a big rooster, and also bought a lot of Chinese medicine for nourishment.

These medicinal herb recipes were obtained by my mother-in-law from Professor Ji of Beijing University of Chinese Medicine. Wang Duoyu still remembered what the recipes were, so he just bought them according to the instructions.

Back at No. 6 Xila Hutong, Wang Duoyu personally went into the kitchen to prepare the two old hens.

The old hen is used to make soup, and the other big rooster is made into Xinjiang Dapanji.

When Fang Zhen and Zhu Ling, mother and daughter, returned in the evening, Wang Duoyu was already prepared.

Seeing this scene, the mother and daughter looked at each other and were overjoyed.

Especially Zhu Ling, she was so touching.

Although the two were rarely together and had conflicts over pregnancy and future, Wang Duoyu still rarely cooked after getting married.

This could be said to be the first time that Wang Duoyu took the initiative to prepare meals and wait for her to come home to eat.

"Duoyu, is your work finished?"

While eating, Fang Zhen asked casually.

Earlier in late July, Wang Duoyu returned from the United States, but he only met with Zhu Ling briefly and then returned to Harbin Institute of Technology.

It is now September 11th, and a month and a half has passed since we last met.

At that time, Wang Duoyu simply said that he had a lot of work to do and would only be able to return to Beijing after school started.

"Well, you can relax for a while." Wang Duoyu nodded with a smile and picked up another piece of chicken thigh for Zhu Ling:

"Eat more. Look in the mirror. You've lost weight. You're not alone now. The little one in your belly is already over five months old. You have to take good care of yourself and the baby."

Then, he received a cold stare.

Has she lost weight?
Zhu Ling checks her weight almost every day because her workplace has such a scale, which makes it very convenient for her to check her weight.

As a result, her weight is increasing every day. She even kept a record herself. From July to now, she has gained nearly ten kilograms.

If her face wasn't so obviously round, Zhu Ling would now think she was a fat person.

The five-month-old baby's belly has started to become round.

So her weight gain is most likely in her lower abdomen.

But her mother interrupted and said:

"Yes, you should eat more, especially more fish. I'm not saying anything bad about you, but your wife doesn't eat much when you're not around. I've made a lot of sumptuous meals like today, but she's trying to piss me off to death."

When this was mentioned, Fang Zhen couldn't help getting angry, and Zhu Ling could only bury her head in her food.

Upon hearing this, Wang Duoyu comforted his mother-in-law on the surface and helped persuade Zhu Ling, but he was smiling bitterly in his heart.

Every family has its cupboard!

His marriage to Zhu Ling seemed like a match made in heaven, but there were still always conflicts.

Everyone has completely different ideas at different times. These different needs and ideas create conflicts with family members at different times.

Take Wang Duoyu himself for example. In his previous life, when he was in high school, he had the opportunity to go to the United States, but his family did not support him, which resulted in him being unable to obtain a visa.

This was because the visa at that time required proof that his family was wealthy, and bank card transactions within six months had to exceed 50,000 yuan.

But in that era, for an ordinary rural family, 50,000 yuan was a huge sum of money.

At that time, his mother's younger brothers were relatively wealthy and could pool their money together to come up with tens or even hundreds of thousands of yuan.

Unfortunately, Wang Duoyu's uncles did not agree, so his dream of going to the United States was shattered.

This was the initial point of conflict. Later, Wang Duoyu got married very late. His family urged him to do so, but he still insisted on doing his own thing, which led to many conflicts with his family.

In fact, these conflicts are not big ones, but there will always be gaps between family members.

"Eat more, don't be afraid of getting fat. I'll help you lose weight."

Hearing what Wang Duoyu said, Zhu Ling almost rolled her eyes at him again.

What kind of comfort is this?

For the next two days, Wang Duoyu stayed at home in Beijing and did not go anywhere. He either cooked for Zhu Ling or wrote and painted at home.

Although Fermat's conjecture has been proved, there is still a lot that Wang Duoyu wants to do.

When he was at Princeton University, Shing-Tung Yau had talked to him about the HYM equation, and Wang Duoyu was very interested in this topic.

First of all, the Yang-Mills equation is an important differential equation, which refers to the Euler-Lagrange equation determined by the Yang-Mills action.

Its theory is based on a gauge theory of the SUN group, or more generally, a compact semisimple Lie group.

Without mentioning mathematical formulas and quantification, let’s just talk about its application. In the future, quantum mechanics will be able to unify the three forces except gravity, all with the help of Yang-Mills theory.

Wang Duoyu is just an ordinary researcher in his research on the theoretical level of physics. He doesn't know his own level, but he is trying hard.

If you can gain something, that would be great. If not, then see how you can grow in the research process.

On the third day, Wang Duoyu received a call at home from Professor Xia Peisu.

The old lady called and invited him to the Computing Institute.

"Who leaked the news of my coming to the capital?"

Once he goes out, he can never have a peaceful life.

At the Institute of Computing Technology of the Chinese Academy of Sciences, Wang Duoyu once again "revisited the old place" and was warmly received by Xia Peisu and others.

"Duoyu, this is our Parallel Computer Project Office, and these are some of our current research results."

Xia Peisu introduced Wang Duoyu to her as a relative and enthusiastically. Shan Yunbo, Chu Yuheng, Tang Xicheng and others behind her looked at Wang Duoyu with complicated eyes.

Some people are extremely gifted and can turn into dragons when they encounter wind and clouds.

But more people are unknown and live an ordinary life.

In the past, Wang Duoyu was just a college student. Although master's students like Shan Yunbo did not feel superior to him, they were not so lowly either.

But now, Wang Duoyu is already a professor, the youngest professor at Harbin Institute of Technology.

It is even more famous abroad.

In July and August, the People's Daily reported frequently on Wang Duoyu's report at Princeton University.

More than 2,000 experts and scholars from all over the world attended this conference. This is a global mathematics event and the only gathering, apart from the International Congress of Mathematicians, that brings together so many top mathematicians, mathematics professors, and mathematics enthusiasts.

Even the Youth Daily, the Industrial and Commercial Daily, the Women's Daily and other newspapers reprinted reports from many foreign newspapers, allowing people like Shan Yunbo to understand how big a fuss Wang Duoyu had made this time.

Some media newspapers, who were keen on watching the fun, even reported on a bet between Wang Duoyu and Shing-Tung Yau, two of the world's leading mathematical figures.

Although it was a friendly bet, some people had bad intentions and reported it recklessly in the newspaper.

In the past July and August, Shan Yunbo and his team had already known the situation in the outside world very clearly through newspapers, radio and other means.

In fact, this is not the scariest part.

The most terrifying thing is that Wang Duoyu launched a distributed computer project at the end of last year, and then it was completely finished before June this year.

In about half a year, a very important scientific research project was completed.

However, Shan Yunbo and his team are still continuing their parallel computer projects, which have not yet been completed.

Why is there such a big gap?
They asked Professor Xia Peisu, and he found out that the research and development of distributed computers is not much less difficult than that of parallel computers.

The reason why the distributed computer project of Harbin Institute of Technology was completed so quickly was mainly due to Wang Duoyu.

Shan Yunbo still remembers Professor Xia Peisu's explanation at the time:
"I'm old, and I'm definitely not as good as young people like Professor Wang Duoyu."

At this time, Wang Duoyu did not pay attention to the expressions of Shan Yunbo and others. After Professor Xia Peisu finished his introduction and listened to the request made by the other party, he nodded and agreed without hesitation.

The parallel computer led by Xia Peisu has three small problems and a framework design problem, and she hopes Wang Duoyu can help sort them out.

After all, she is a 57-year-old old lady. She is still in good health, but her brain is not as fast as before and her energy is not as good as before.

Even without mentioning the help the other party had given him before, Wang Duoyu would feel obliged to do so just based on the other party's appreciation.

So, for the next few days, he stayed at the Institute of Computing Technology to help them sort out issues such as system architecture.

Time passed slowly. When it came to September 16th, a phone call came. Half an hour later, the old professor Shiing-Shen Chern appeared in front of Wang Duoyu.

"Professor Chen, why did you come here in person?"
