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

Chapter 227: Liu Xiaoli was hit, Zhu Ling came to the door

On the evening of May 6, 1983, at Wang Duoyu’s home on the campus of Harbin Institute of Technology.

Zheng Baoyin and Wang Jianchao came with two large boxes of dried seafood and wine. As soon as they entered the door, their loud voices rang out.

"Uncle (Uncle Nine), we are here."

Wang Duoyu had just come out of the room. Because Liu Xiaoli was so excited, she cried several times in the hospital and even fainted.

In other words, Wang Meili, this big shot, actually believed Liu Xiaoli's words and did not inform her ninth brother to come to the hospital.

Fortunately, Liu Xiaoli did not encounter any accidents. After the doctor gave her acupuncture, she finally calmed down a lot and came back with the pregnancy-maintaining medicine.

The good thing about studying at Harbin Institute of Technology is that the hospitals are very close and the medical resources are very good.

So if you have any health problems, you can always see a doctor.

Liu Xiaoli was pregnant, and Wang Duoyu was very happy, so he came in to see her, but she had already fallen asleep, so he didn't stay long.

"Why did you bring so many things here? What are these?"

Seeing Zheng Baoyin and the other man carrying a large box in, Wang Duoyu asked curiously.

"Uncle Jiu, these are the seafood I purchased from Dalian in the south. Baoyin bought these from abroad. They are said to be very beautiful sea cucumbers with very high nutritional value."

Hearing Wang Jianchao's words, Wang Duoyu shook his head and said:

"You don't have to give me so much. We can't eat so much. You can take some back later."

Upon hearing this, Zheng Baoyin immediately waved his hand and said:

"Uncle, this was originally picked for you. We've already saved some for ourselves, and we often come to your house for dinner. Hehe, any delicious food or drink you have at home has long been eaten up by us."

This is true!

Although every time Zheng Baoyin and his friends came to Wang Duoyu's house for a meal, they brought their own ingredients and cooked them directly at Wang Duoyu's house.

But the snacks, fruits, etc. stored in Wang Duoyu's house will soon be swept away by Wang's relatives.

As a result, Liu Xiaoli had to go out and purchase a batch the next day after every party.

Otherwise, when guests come to my house, there will be nothing to entertain them.

As for the gifts brought by Lao Wang's relatives, most of them were mountain products, which were not suitable for entertaining guests. Liu Xiaoli bought some biscuits, cakes, seasonal fruits, etc.

"Yes, Uncle Jiu, I heard that Aunt Xiaoli is pregnant. These are just the right supplements for her." Wang Jianchao added:
"We still have old hens at home. I'll call my hometown and ask them to prepare some and bring them over to Aunt Xiaoli to supplement her nutrition."

Aunt Xiaoli!!!
This is what the Wang family’s relatives call Liu Xiaoli.

It’s not that they don’t call Liu Xiaoli Aunt Jiu, but everyone is feeling quite awkward now and doesn’t know how to address her.

From a legal perspective, Liu Xiaoli and Wang Duoyu have no relationship and they are not husband and wife.

Although they are husband and wife in reality, they are not husband and wife in name only.

Who made Wang Duoyu unwilling to get the marriage certificate again?
From Chen Qingwan to Zhu Ling, Wang Duoyu has been divorced twice. No matter who it is, he probably won't remarry easily, right?
Anyway, Wang Duoyu is not willing to remarry. He is really afraid that he will get divorced again.

If we look at the situation in the original time and space, Wang Duoyu should not have chosen Liu Xiaoli, but should have chosen Lu Ruoxi or Yuan Xueyi.

But before he married Zhu Ling, he had already separated from Liu Xiaoli once. Afterwards, Liu Xiaoli proved with practical actions that she still had feelings for Wang Duoyu.

People are all made of flesh and blood. Wang Duoyu can't ignore Liu Xiaoli and choose Lu Ruoxi or Yuan Xueyi, right?

But in the end, because he had a shadow on his heart about marriage, he stopped talking about getting married.

Since there was no bond of marriage and no wedding banquet, Zheng Baoyin, Wang Jianchao and others didn't know how to address her, so they simply called her Aunt Xiaoli.

After all, the sisters Wang Meihe and Wang Meili also call Liu Xiaoli "Sister Xiaoli".

"Old hen? You're exaggerating a bit, aren't you?" Wang Duoyu said happily.

"We don't have many old hens at home. What will we do if we catch them all and bring them back home? Besides, it's only May now. Where can we find a few old hens?"

Generally speaking, people in rural areas would go to the market to catch chicks and take them home to raise after the Spring Festival. They would kill the last one or two roosters during the Qingming Festival to offer sacrifices to their ancestors. If people wanted to eat chicken after that, they would have to wait until the Mid-Autumn Festival or the Spring Festival.

After all, from the Qingming Festival in April to the Mid-Autumn Festival, that's half a year, enough time for those little stupid chickens to grow up.

Wang Meifeng interrupted at this time:

"Why not? Before I left last week, my eldest and third brothers still had two old hens, and I also have one old hen."

Dahonggou Village is close to the mountains. Before 1976, every household raised chickens in the mountains and arranged people to help look after them. They also had domesticated Chinese pastoral dogs to help look after them.

Later, with the reform and opening up, every household no longer had to hide the fact that they raised chickens.

Take the old hen raised in Wang Meifeng's home for example. This old guy has been raised for six or seven years and can help hatch forty or fifty chicks every year.

It can be said that this is one of her family's sources of income.

So when Wang Duoyu heard this, he immediately shook his head and said:

"Eighth sister, this is absolutely not possible! This is the old hen your family uses to hatch chicks. You absolutely cannot kill it and eat it."

Among Old Wang's relatives, many families raise hens, just like Xu Quanhua, the son of Wang Duoyu's second sister. He not only raises hens, but also several wolfhounds.

These domestic dogs are the family's right-hand men. They can help catch prey and guard the house to ensure that the chickens, ducks and geese in the house are not eaten by rats, weasels, foxes and other animals from the mountains.

His eighth sister heard this, but shook her head and said:

"Raising these chickens consumes food, and they are meant to be eaten. Lao Jiu, just leave them alone."

When Zhu Ling was pregnant with Wang Junhong, the Wang family’s relatives did not help. Now that Liu Xiaoli is finally pregnant, the Wang family will definitely not miss the opportunity.

In addition to the old hens, several families actually still have a lot of big roosters, waiting for Liu Xiaoli to get pregnant.

Even if Liu Xiaoli didn't get pregnant, in a few months, the sisters Wang Meihe and Wang Meili would be in confinement after their childbirth, and they would be able to use it then.

Upon hearing this, Wang Duoyu could only shut up.

His eighth sister has already made up her mind, and there is nothing he can do to stop her.

Besides, it’s just a few old hens, not a big deal, there’s no need to fight over it.

"It's time to eat!" Liang Xiufen came out of the kitchen and shouted, and everyone immediately took action.

Soon, the huge living room was divided into two tables. There were not many people coming this time, but not too few either. Two tables were not enough to accommodate them, and three tables were not appropriate.

So some people pick up their food and eat it while standing.

It's a big pot meal, that's what it is.

Just make do with it!
"Baoyin, how is your elder brother now?"

At the dinner table, when everyone was eating happily, Wang Meifeng suddenly asked a question, and the whole room suddenly became quiet.

The smile on Zheng Baoyin's face disappeared in an instant.

"Eighth Aunt, how should I put it, my eldest brother..."

His mother is Wang Duoyu's fourth sister, and Wang Meifeng is Wang Duoyu's eighth sister, so Zheng Baoyin calls Wang Meifeng his eighth aunt.

When it comes to his elder brother Zheng Baoqiang, he is naturally not in a good mood.

In July last year, his eldest brother and his eldest sister-in-law Wei Shufen suddenly decided to resign.

After approval, the couple went to Guangzhou in the south.

There would have been nothing wrong with it, after all, everyone has their own aspirations, but Zheng Baoqiang and his wife are still selling Uma clothing, and they even produce it themselves.

It is illegal to produce Youma clothing on your own without obtaining authorization from Youma Clothing Factory.

After being warned by Zheng Baoyin, his elder brother still did not give up and directly registered another brand: Bayu Garment Factory.

Wow, he just took a name from each of the two clothing brands, Babos and Uma, to form a new clothing brand. He really knows how to ride on the popularity and traffic.

But it's no use.

The product quality is not up to standard, the brand has no advantages, and there is no advertising.

In addition, a huge bug bred inside their Bayu Garment Factory, which swept away all their profits and almost caused their factory to go bankrupt.

Because of this, Zheng Baoqiang and Wei Shufen are now struggling to run their business and have repeatedly asked their younger brother Zheng Baoyin for help.

Every time, Zheng Baoyin gave money privately to help them instead of using the channels of Youma Garment Factory to help them.

After all, public and private affairs must be clearly distinguished, and Zheng Baoyin is very clear about this.

If he helped his elder brother and sister-in-law, he did not ask for their gratitude, but hoped that they could live a good life and run their factory well.

Unfortunately, his elder brother and sister-in-law had already changed their hearts and were no longer the kind and honest elder brother they used to be.

After things got a little better at the Bayu Garment Factory, his elder brother actually followed the trend in Hong Kong and Taiwan and started keeping a mistress.

In other words, his eldest brother's sister-in-law doesn't know yet, otherwise, his eldest brother's family will definitely be torn apart.

To be honest, Zheng Baoqiang is really awesome. Because he runs a clothing factory, he has indeed been exposed to a lot of fashion circles. However, he didn't learn anything good, but he learned all the bad things.

In contrast, his younger brother Zheng Baoyin has been traveling in the United States for such a long time and has no such bad intentions.

Wow!

In addition, Zheng Baoyin felt very uncomfortable every time he met his elder brother and sister-in-law in Guangzhou.

Because his elder brother and sister-in-law would only cry poor to him, hoping that he could help them. They said a lot of words of gratitude, but every time they entertained him, they were still so stingy.

Because of this, how could Zheng Baoyin be in a good mood when he mentioned his elder brother and sister-in-law?
Wang Duoyu and others didn't know much about Zheng Baoqiang's affairs. They learned everything from Zheng Baoyin.

Wang Duoyu also did not ask anyone to investigate Zheng Baoqiang and others. He only knew that Zheng Baoqiang had previously used the name of Youma Garment Factory to sell products, and later changed the name to Bayu Garment Factory.

To be honest, the name of Bayu Garment Factory is quite nice to hear, but it's a pity that Zheng Baoqiang doesn't know how to run it and can't even copy homework.

Otherwise, he might have been able to build up the Bayu Garment Factory.

How should I put it? Sometimes, people are destined to achieve what they will achieve in this life.

Differences in personality, vision, pattern, etc. can really determine a person's level of achievement. After all, whether a person can succeed is not just determined by one dimension, but by multiple dimensions.

After hearing about Zheng Baoqiang's recent situation, Wang Meifeng and others couldn't help but curse: ungrateful bastard!

That’s true. Zheng Baoqiang is obviously a shareholder of Want Want Group, and Wang Duoyu treats him so well, but he insists on leaving Want Want Group.

In fact, it is also because Zheng Baoqiang and his family have already moved to Guangzhou. Otherwise, it would not be as simple as just a few words of scolding.

With the fighting power of people like Wang Meifeng, they will definitely scold Zheng Baoqiang and Wei Shufen to the point that they doubt their lives.

"Forget it, let's not talk about these unhappy things." Wang Duoyu shook his head and took the initiative to cut off the topic:

"Eighth sister, how is things at home now? Have you planted the fields? How are my eldest and third brothers doing?"

Talking about these things, Wang Meifeng suddenly became more energetic.

In fact, if it weren't for her man Xue Lisheng working in Bingcheng, she wouldn't have come here.

After all, there is a lot of farm work to do back home now.

During the days she came to Bingcheng, she was worried about the chickens, ducks, pigs and cows at home almost every day, fearing that Xue Yuqing and the other little ones would be too busy to take care of them.

The little girl Xue Yuqing is already thirteen years old this year. In her hometown in the countryside, she has six or seven years of experience in raising pigs and six or seven years of experience in cooking.

Which child in a rural family doesn't start helping with farm work at the age of three or four? By the age of five or six, they are already able to help with some farm work.

When they are seven or eight years old, children are responsible for chores such as washing clothes and cooking, and adults do not need to worry about them.

This is also the main reason why Wang Meifeng was able to leave home and come to Bingcheng. After all, with the help of thirteen-year-old Xue Yuqing and twelve-year-old brother Xue Wenwu, she can certainly handle the work.

The happy time passed quickly as everyone chatted and laughed.

After eating and drinking, Liang Xiufen and the others helped wash the dishes and cleaned up the kitchen before leaving.

"Uncle Jiu, we'll go back first. The food is still hot in the pot in the kitchen. When Aunt Xiaoli wakes up, you can tell her."

"Okay, I understand. Thank you. Be careful on your way back."

Wang Duoyu nodded, watched them leave, turned around and took Zheng Baoyin and Wang Jianchao back to the study.

Zheng Baoyin had just returned from abroad and must have work to report. Wang Duoyu would of course listen to it and then give strategies and adjust the direction in a timely manner.

In the study, Wang Duoyu learned from Zheng Baoyin about the current situation of Youma Clothing in the United States. In April, Youma Clothing's revenue in the United States exceeded 20 million US dollars.

Breaking 20 million US dollars in a single month is an impressive figure.

With an average order value of US$29.9 and US$39.9, we were able to generate US$21.07 million in revenue. How should I put it? It's really amazing.

"Uncle, although our revenue is pretty good, I'm really annoyed with Nielsen Research. They're terrible. The difference between their survey data and our actual revenue is within $100,000."

As he was speaking, Zheng Baoyin suddenly complained angrily:

"What I dread most is seeing Nielsen's survey reports. Their reports are very accurate, and I don't know why anyone would do such a thankless task."

"And how do they make money from this kind of business research and analysis?"

Wang Duoyu couldn't help but laugh when he heard this. He looked at Zheng Baoyin and Wang Jianchao and asked, "What do you think?"

Both of them shook their heads, saying that this was due to insufficient information exposure.

In fact, if Zheng Baoyin had not gone to the United States, Wang Jianchao would not have heard of Nielsen Research Company.

This is an information problem. Many people will never be exposed to such information until they die, nor will they know what kind of companies there are under the same sky in this world.

For example, many people in later generations have never heard of iPhone.

"You can't guess how they make a profit because you don't understand their business model. For example, I need to start a clothing company now. I have money, but I have no people and I don't know how to do it. So what should I do?"

"At this moment, there is a company that can provide me with very detailed market research reports, competitor analysis, consumer behavior analysis and other reports. Do you think I would be willing to pay them?"

Zheng Baoyin and the others widened their eyes when they heard this. Do they need to spend money to buy this kind of information?
"Uncle Jiu, how could someone be so foolish as to buy such information? Can't they just investigate on their own? Besides, aren't reports like these trade secrets? Why doesn't this research company just make the money themselves?"

Wang Jianchao asked in confusion. Wang Duoyu shook his head and explained it to them in detail.

After a while, Wang Duoyu brought the topic back to the topic and made all-round adjustments to Youma Clothing's self-operated store model in the United States.

"Baoyin, for the next stores, we will adopt both leasing and purchasing methods at the same time. We cannot use leasing for all stores."

"Although the prices in the US are very high, it doesn't matter, we still want to buy it."

"But we can't buy it directly under the name of Yuma Clothing, we can arrange for a shell."

Hearing Wang Duoyu's words, Zheng Baoyin couldn't help but widen his eyes.

In fact, Wang Duoyu also knew that even if he put on a shell, when the United States wanted to investigate, it would be able to find out quickly.

But having a shell is better than having no shell, right?
Telling people openly that Youma Clothing has purchased many stores in the United States is like delivering the "handle" to their doorstep.

There is a shell blocking it. If Uma America signs a lease contract with the subsidiary of this shell, then others will not notice this matter at the first time.

Unless there is a real conflict, then others will conduct an in-depth investigation.

Besides, if something really happened, Wang Duoyu could easily escape from the shell in advance to avoid such a huge loss.

On the other hand, prices in the United States will certainly continue to rise over the next few decades, including real estate prices. Rents will also rise, so while it may seem like the money is invested in the United States, Wang Duoyu doesn't want to let Americans pocket the profits from even the commercial shop rentals.

It is now 1983, and the business vitality in the United States is still insufficient. After all, the economic crisis has just ended.

Apart from adjusting this, Wang Duoyu did not make any adjustments in other aspects.

Anyway, Yuma Clothing is following the routine and setting up shop all over the United States.

All the profits were taken away by the domestic company of Uma Clothing, and the profit of Uma America was not much.

Therefore, there is nothing to adjust, and it is the best solution at the moment.

In addition, you should also pay attention to the actions of dealers.

After chatting for about fifty minutes, Zheng Baoyin and the others left.

Wang Meili and her sister just helped to coax the little guy to sleep. That was because the little guy had a lot of fun this afternoon and evening, so he could fall asleep as soon as he touched the bed without any coaxing.

After a while, Li Yuanchao, Lu Qingsong and others came over, and the two sisters went back.

After they all left, the house became completely deserted.

Fortunately, the house has been cleaned up and Wang Duoyu doesn’t need to worry about it.

At this time, Liu Xiaoli suddenly woke up.

"They're all gone?"

"Well, the kitchen left some food for you. It should still be warm."

"I don't want to eat more fish. I want to share a good news with you. I'm pregnant!"

Wang Duoyu pretended to have just heard the news, showing expressions of surprise and joy. Liu Xiaoli was even happier. She hugged his waist, and tears welled up in her eyes again in excitement.

In order to get pregnant, she tried so hard that she took a lot of Chinese medicine.

In fact, her case is relatively lucky, there is no so-called ectopic pregnancy, otherwise she would be really miserable.

The causes of ectopic pregnancy are very complicated, but most of them are likely due to abnormal fallopian tube function, salpingitis, etc.

Moreover, the medical level of this era, both in terms of hardware and software, is not very good. Once an ectopic pregnancy occurs, it is very likely to occur again.

So at this time, we can only rely on in vitro fertilization, but this technology will not appear until around 1988.

"Don't cry, you should be happy. You are pregnant now, so don't be so excited."

"Yeah, I know, I know. But I just can't help it."

That night, Liu Xiaoli snuggled in his arms and slept very soundly. It was also the first time that the two of them did not do fill-in-the-blank exercises during their periods.

In the next few days, because Liu Xiaoli was pregnant, Wang Duoyu tried to make more time to come back for dinner, and he would stay a little longer for each meal.

At noon that day, Wang Duoyu and his friends had just finished lunch when the little guy suddenly rushed towards Liu Xiaoli.

"Mom, look"

Bang!
Liu Xiaoli had no time to react and was hit in the stomach by the little guy, which made her face turn pale instantly.

Wang Duoyu, who was standing by, finally reacted at this time and quickly pulled the little guy to his side.

"Xiao Li, how are you?"

After expressing concern for Liu Xiaoli, Wang Duoyu slapped the little guy again, "Wang Junhong, did I ever tell you that you are not allowed to offend your mother like this?"

".Don't scold him." Liu Xiaoli was extremely worried at this moment, fearing that something might happen to the baby in her belly.

But she comforted herself that it was only four weeks now, so it shouldn't be a big deal, right?

The little guy was a little stunned by the harsh words, and then he reached out to hug his father:

"Dad, even though you are mean to me, I still love you, but I feel like crying."

puff!

Liu Xiaoli couldn't help but laughed.

Wang Duoyu couldn't help it either. It was really annoying and lovable to see this little brat doing this.

But what does a two-year-old child understand?

After this little episode, Wang Duoyu picked up the phone and called Wang Jianchao.

"Jianchao, can you help me ask who can come to my house and help me take care of Junhong for a while? This little guy is too naughty."

"Oh, okay, Uncle Jiu, I understand."

Soon, Wang Jianchao called back and said that his second sister-in-law could help. His second sister-in-law was Liang Xiufen.

In fact, his sisters Wang Yufen and Wang Yumin also wanted to help take care of the baby, but they were only eighteen or nineteen years old and not suitable, so they were rejected by Wang Jianchao.

"Okay, then let your second sister-in-law come over." Wang Duoyu did not hesitate and decided on this matter directly.

Liu Xiaoli didn't say anything. After all, she was pregnant now and she really had to be careful.

If she had a miscarriage because of little Wang Junhong, no one wanted to see that.

After a while, Wang Jianchao personally drove his second sister-in-law over.

"Uncle Jiu, I'll take care of Junhong. I'll definitely take good care of him."

Wang Duoyu nodded, and after handing the child to Liang Xiufen, he took Liu Xiaoli to the hospital. When Liang Xiufen heard this, she followed them.

However, before the results came out, Liu Xiaoli asked him to go to work first.

"Okay, then you guys pay attention."

After saying that, Wang Duoyu went to work.

In the blink of an eye, it was evening. Liu Xiaoli was not in any accident. Although Wang Junhong bumped into her suddenly, she was not hurt.

Although it was a false alarm, this incident also sounded a wake-up call for Wang Duoyu and Liu Xiaoli. Children over two years old are very curious, so more attention needs to be paid to this matter.

"Xiu Fen, when you have nothing to do, teach him to recite some ancient poems."

"Okay, Uncle Jiu, I know, no problem."

Liu Xiaoli also said that she would keep an eye on it.

The reason for this is to find something for the little ones to do, or to take them out for walks more often. The free-range model is the best way to raise children.

There is nothing you can teach a child who is over two years old. You can only take it slow and show more patience and care.

Time flies, and it is late May. On the 23rd, Charles Feefman and others came to Wang Duoyu's office to discuss the second proof paper of the geometric Langlands conjecture.

They have been conducting the review for more than ten days, but still encountered many problems.

The proof process of equivalence functor is too complicated.

Even with the brains of Charles Fefferman and others, they could hardly understand it. After spending more than ten days, they came to Wang Duoyu with their questions.

If Shing-Tung Yau and his group were teenagers, then the first proof paper would only be of the difficulty level of a junior high school student, while the second paper would be of the difficulty level of a university student.

The difficulty coefficient increases exponentially, which of course makes them a little crazy.

Wang Duoyu was surrounded by them and felt a little helpless.

After chatting for two hours, Wang Duoyu had to take the initiative to say:
"Well, I think you should spend a little more time reviewing it. If necessary, you can always borrow the computers at Harbin Institute of Technology to verify it."

Upon hearing this, Qiu Chengtong and others shook their heads.

The computers at Harbin Institute of Technology are no different from those at the Ice City Institute of Advanced Studies.

Because both software and hardware are updated synchronously, there will be no difference.

Besides, they are all mathematicians. They only use computers in very rare cases. Most of the time, they rely on their own brains.

It’s not that they are unwilling to use high technology, but that they trust their own brains more.

"When do you plan to do your monthly sharing next month? I hope you can do it earlier, okay?"

David Bryant Manford asked, and the others nodded in agreement, but Wang Duoyu shook his head.

"Even if I shared it earlier, would you have been able to understand more?"

Today is already the 23rd, but they still haven't fully understood the proof of equivalence. If Wang Duoyu completely breaks down this proof, he will definitely need to add hundreds of pages to his paper.

The specific number of pages depends on how much they can understand.

There are also gaps between top mathematicians, and the gaps between them are also very large.

For example, Shiing-Shen Chern and Shing-Tung Yau are master and apprentice, but it cannot be said that Yau's mathematical talent far exceeds that of his master.

Because being an all-round math genius is different from being the top in a particular field.

Another example is Henri Poincaré, a versatile mathematician with comprehensive knowledge in mathematics and its applications, covering number theory, algebra, geometry, topology, celestial mechanics, mathematical physics, multi-complex function theory, philosophy of science and many other fields.

Among the more famous mathematicians of this century are the deceased Bertrand Russell, Henri Poincaré and von Neumann, as well as Alexander Grothendieck who has changed his career.

The latter is the founder of modern algebraic geometry, and his main research includes the duality of continuous and discrete, the Riemann-Roch-Grothendieck theorem, stable topology, non-Abelian algebraic geometry, etc.

Among them, the Riemann-Roch-Grothendieck theorem generalizes the Riemann-Roch theorem to arbitrary high-dimensional algebraic varieties based on algebraic curves and algebraic chimneys, and during this period, topological K theory was developed.

However, when Grothendieck won the Fields Medal in 1966, he refused to go to the Polar Bear Empire to receive the award, and instead went on a trip to the Monkey Peninsula the following year.

As we all know, in 1967, there was still a civil war in the Monkey Peninsula. It was amazing that this person traveled there.

Later, Grothendieck withdrew from the mathematics community. To be more precise, he was abandoned by the mathematics community because he applied for jobs at the French Academy and the French National Center for Scientific Research, but was rejected by both.

So since 1973, he has studied counter-orthodox culture and is now a professor at the University of Montpellier.

This guy wrote four books between 1980 and 1995, the most famous of which is the autobiographical book "Harvest and Seeding" written in 1985.

The two thousand pages of rotation can be summed up in three relationships: women, mathematics and meditation.

It must be said that Grothendieck's mathematical talent is indeed amazing, but it's a pity that he is too conceited.

"Then let's take a look."

After a moment of silence, Qiu Chengtong responded.

Although Charles Fefferman and others were reluctant to admit it, they could only nod helplessly.

The gap between them and Wang Duoyu is huge.

You may not have noticed it before, but in some cutting-edge fields, this gap can make people despair.

In fact, the reason why they agreed to stay in the Ice City Institute of Advanced Studies was, to a certain extent, to surrender to him.

The same thing happened to Alexander Grothendieck. After he returned to Paris from the United States, he was also surrounded by many top mathematicians.

Among his most outstanding students were Pierre Deligne and Michel Renaud, among whom Pierre Deligne won the Fields Medal in 1978.

Although Charles Feefman and others did not know how glorious the Grothendieck era was, now is the era of Wang Duoyu, and they certainly know very well how awesome Wang Duoyu is.

"Well, that's it. If there aren't any major surprises, then next month's math sharing will still be around the 4th or 5th."

Wang Duoyu smiled and nodded.

After hearing this, Qiu Chengtong and others left with satisfaction.

Since they couldn't get more detailed proof from Wang Duoyu, they could only go back and study it slowly.

After this day, Wang Duoyu's work and life returned to normal.

In the computational fluid dynamics simulation software project department, Wang Duoyu came here that day, and Jiang Boju and others were discussing how to solve the problem of fluid lubrication based on computational fluid dynamics methods.

Regarding this issue, Wang Duoyu did not speak immediately, but listened quietly to their discussion.

You should know that most of the global theoretical research on fluid lubrication is based on the Reynolds equation derived from the Navier-Stokes equation more than half a century ago. Various simplifying assumptions were made in its derivation, such as ignoring the inertia term, assuming that viscosity and density are constant, etc.

This assumption simplifies the solution process, narrows the scope of the problem, improves computational efficiency, and has been shown to be applicable to approximate solutions to oil-film fluid lubrication problems when the ratio of oil film thickness to contact length is relatively small.

Jiang Boju said eloquently:
"However, if the oil film thickness and contact length are large, if the oil film between the walls contains geometric disturbances, if transient dynamic loads and high pressure are taken into account, and if other factors are taken into account, the neglected effects will be significantly enhanced. In this case, the approximate Reynolds equation becomes inappropriate."

As a professor of mathematics at Peking University, Jiang Boju's research on mathematical theory is very in-depth. The entire research team listened carefully to his presentation of the problem.

The computational fluid dynamics simulation software project was established in March 1981. At that time, Jiang Boju had already left Peking University and directly joined Harbin Institute of Technology, and then entered this project.

And since then, he has always been one of the most important technical leaders of this project.

Harbin Institute of Technology has been able to launch products such as cordless telephones, simulation software, HS213 memory, etc. in the past few years. In addition to Harbin Institute of Technology itself, it is also because there are more new members joining Harbin Institute of Technology. Everyone works together, which has promoted the overall development of Harbin Institute of Technology.

Similar to Jiang Boju and others.

People like Shing-Tung Yau are not actually considered as such, because they only conduct theoretical research in mathematics, not scientific research in the application of mathematics.

Of course, this does not mean that people like Shing-Tung Yau are not important. On the contrary, people like Shing-Tung Yau, John Milnor, and Charles Feefman are researchers in mathematical theory, and their research is about theoretical studies that may be applied to real life in the next decades, hundreds of years, or even thousands of years.

What they are doing is theoretical and ideological guidance, which is the most cutting-edge scientific research and theoretical research work.

Mathematical applications are aimed at current scientific research and are scientific research work that can be seen and touched immediately.

After listening for a while, Wang Duoyu suddenly interrupted their conversation and said:

"Professor Jiang, if I remember correctly, our current simulation software already has various grid-related model software for solving fluid lubrication problems. The process for directly using the Reynolds equation to solve fluid lubrication problems should be roughly the same, right?"

Jiang Boju heard this and nodded in agreement:
"Yes, they are indeed the same. This is the key point I'm going to talk about next. The steps involved in establishing the physical model, converting the model into finite elements, defining the domain, setting the initial field and boundary conditions, selecting the solution model, solving the equations, defining the solution parameters, performing the calculations, and post-processing the data are actually the same. Now let's look at the screen."

The simulation software is displayed on the computer screen. The diagram above is a model for solving fluid lubrication problems, as well as some numerical values.

The Reynolds equation is generally discretized using the finite difference method, while the computational fluid dynamics method currently used in simulation software usually uses the finite element method for discretization.

Since the finite volume method is used for solving, more accurate element discretization can be obtained compared with traditional methods, and more complex and higher precision problems can be solved.

Wang Duoyu listened and nodded in agreement from time to time.

By the time he left the office, two hours had passed.

Su Zhenghuai had already come up to him, with a strange look on his face, and spoke hesitantly:

"Professor, your family just called and said they have guests."

"Who's here?" Wang Duoyu frowned. Su Zhenghuai shouldn't have this expression. Couldn't he just say it directly if there was something wrong?
"Professor, yes. Your son's mother is here."

Zhu Ling came to see his son again?
In the past few months, Zhu Ling has come to Harbin Institute of Technology to visit Wang Junhong every once in a while, apparently trying to restore the relationship between her and her son.

Perhaps, she hoped to successfully remarry Wang Duoyu before Liu Xiaoli became pregnant, so that she could return to the peaceful relationship they had before.

Because Liu Xiaoli hadn't been pregnant for so long, every time she came, although Zhu Ling didn't laugh at her, she would always hug Wang Junhong and say, "You're so good, son. You're my biological son. Blood is thicker than water."
It’s heartbreaking to kill someone!

Liu Xiaoli was always very angry.

It can be said that Zhu Ling’s stimulation was one of the main reasons why Liu Xiaoli was so eager to have a child.

Now that Liu Xiaoli is pregnant, Zhu Ling definitely won’t dare to act up anymore, right?
But when Wang Duoyu heard that Zhu Ling was coming to his house, his face suddenly changed because he was still worried that Zhu Ling would lose her mind.
