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

Chapter 224, Don’t be confused, menstruation is also a period!
March 5, 1983, the 21st day of the first lunar month, is not a good day. Wang Duoyu is not talking about the weather, but the luck.

When he met Lu Ruoxi when he went out, although she was a great beauty, Wang Duoyu really didn't want to make a mistake.

So he simply accompanied Lu Yangui and the others for a while, and then returned to the office in the mathematics department's teaching building.

At this time, Charles Fefferman and Edward Witten were already waiting at the door.

After meeting, the three of them exchanged pleasantries, and of course it was Charles Fefferman who introduced them.

The arrival of the two people surprised Wang Duoyu a little. After learning that the other party was Edward Witten, his expression became even more surprised.

"Edward, aren't you a professor of physics? Why are you here to see me? I mean, shouldn't you be in the physics department?"

Edward Witten spread his hands and complained helplessly:

"You've already attracted the world's top mathematicians to Ice City. I have no choice but to come, unless I just want to waste my whole life."

As soon as these words were spoken, laughter suddenly broke out in the office.

The other party's "complaint" made both Wang Duoyu and Charles very happy.

After chatting for a while, Edward Witten made a request, which was to hope to communicate more with Wang Duoyu.

Upon hearing this, the latter said that there was no problem. If there were any problems, they could come to him at any time as long as he had time.

There is also a monthly math sharing every month, so even if you don’t see him normally, you can definitely see him on the monthly math sharing.

After receiving Wang Duoyu's personal guarantee, Edward Witten was completely relieved.

After all, his main purpose of coming to Harbin Institute of Technology was to improve his mathematical ability.

However, his subsequent communication with Wang Duoyu made him so happy that he almost jumped up, because the latter's research in physics was also not weak, even higher than his.

Especially in the fields of metaphysics, mirror symmetry, supersymmetry, topological quantum field theory, etc., aren't those the areas he is best at?

Almost instantly, he felt like he had found a soulmate.

"God damn it, I should have met you earlier. Really, if I had met you earlier, I might have already published several top journal papers."

An hour and a half later, Edward Witten suddenly said with regret.

This sentence made Wang Duoyu want to laugh, because even if they had met earlier, his research on physical theory might not have been so in-depth.

Knowledge needs to be accumulated.

Wang Duoyu's knowledge of physics and theoretical research are mostly based on some papers he read in his previous life, and he gradually formed his own understanding after communicating with physics professors such as Yang Zhenning and Qian Xuesen in this life.

But to be honest, his talent and research in physics are indeed not as good as in mathematics.

Otherwise, he would have published more research papers on physics instead of focusing more on mathematics.

"It's not too late for you now." Charles Fefferman said with a smile: "Let's go, it's already six o'clock. I'll treat you to dinner at Qingyun Tower. I tell you, the food there is absolutely delicious."

After hearing what the other party said, Wang Duoyu smiled and refused, saying that he had to go home for dinner.

People like Charles are all the embodiment of gluttony.

After arriving in Ice City, forget about the holidays. Wang Duoyu is not sure how these people find local food when they go to Beijing and other places.

But every time they are at Harbin Institute of Technology, they come in turns. Yesterday they went to Quanjude, today they went to Qingyunlou, tomorrow they went to the Hunan restaurant, the day after tomorrow they went to the Cantonese restaurant, the day after tomorrow they went to the Sichuan restaurant, and then to the Harbin Institute of Technology cafeteria.

No matter what, their meals are definitely different every day, spicy, fresh and fragrant, and you can eat anything because they are really delicious.

Take Cantonese restaurants for example, there are as many as six or seven of them in front of the gate of Harbin Institute of Technology. If you eat at a different one every day, you won’t eat the same thing twice in a week.

This is also the main reason why Charles Fefferman gained weight.

"No, Professor Wang, we only eat, not drink."

Charles tried hard to invite her, but Wang Duoyu still refused. "I haven't seen my child for a day. I have to go home to see him."

Seeing this, Charles could only express his regret helplessly, and then said that he must not refuse him next time.

After Charles and Edward left, Wang Duoyu simply packed up and left the office.

He is responsible for tidying up all the documents in his office himself. If it is cleaning, that is the job of the security department and no one else is allowed to touch it.

Just as he was about to go out, the phone on his desk rang. It was Lu Yangui calling personally, inviting him to have dinner together.

"Boss, I have to go home for dinner"

Wang Duoyu refused, and his reason was quite strong. After all, he had to go to Beijing the day after tomorrow.

Upon hearing this, Lu Yangui did not force him, but instead asked him to come to his house later and sit for a while.

"How about this, leader, you come to my house for dinner?" Wang Duoyu could only invite tactfully.

He met with Lu Yangui in the afternoon. The other party did not mention dinner at that time, but now he suddenly invited him to dinner before dinner time. After he refused, he asked to go to his house later. This was obviously a trap for Wang Duoyu, so that he would take the initiative to invite him to dinner.

My goodness, are all leaders so cunning?

It’s not that Wang Duoyu hasn’t thought about these things, but he is too lazy to think about them and has no intention of exposing the other party.

After all, no matter what, Lu Yangui is the leader, and it would be bad if he were exposed.

"Okay, I haven't been to your house yet, but if I go to your house for dinner now, is it still okay to cook?"

"Don't worry, boss. It will be fine. My sister and the others are at home. I'll call you shortly. It will be quick."

Wang Duoyu was secretly complaining, but he remained polite on the surface.

His two younger sisters would come back to his house for dinner every other day, and today was the day they came home for dinner.

The two sisters are pregnant, but their pregnancy is not obvious yet, so it doesn't matter much.

"Okay, then I'll have a meal."

After hanging up the phone, Wang Duoyu immediately called home and told Liu Xiaoli and the others to prepare meals for a few more people.

In Wang Duoyu's opinion, Lu Yangui definitely did not come alone. At least he brought his granddaughter with him.

More than twenty minutes later, Wang Duoyu returned home, and the little guy brought two puppies to welcome him home.

"Dad, hug!"

Two wolf-blue dogs, one on the left and one on the right, guarded the little guy like door gods.

But the two little puppies are also quite miserable. Since returning to Harbin Institute of Technology, they have been bullied by Wang Junhong a lot.

He stepped on their tails from time to time and rubbed them in various ways. In short, he did a lot of harm to these two little puppies.

The two puppies were very docile and never bit the little guy.

In fact, if they show such signs, they must have been sent away.

A dog that is not tamed can definitely be cooked.

It’s just that neither of the puppies’ parents have ever bitten anyone, and they are also the two most docile ones. No matter how you pull them, they will only wag their tails and will not bark or bite anyone. They are very honest.

Holding the little one, Wang Duoyu came to the kitchen. At this time, Liu Xiaoli and Wang Meihe were busy cooking.

"Brother, who is this guest? Why do you need to add so many dishes at the last minute?"

Wang Meihe turned around and asked, and Wang Duoyu simply replied, "He's just a leader, don't ask so many questions."

If Liu Xiaoli and the others were to cook alone, it would definitely not be enough, so Wang Duoyu asked Su Zhenghuai to help and go to Qingyunlou to pack up three dishes.

After chatting for a while, Lu Yangui came to visit with a few people.

To be honest, Wang Duoyu's house often has guests, and the little guy didn't think there was anything wrong, but it was the first time that Wang Duoyu felt that entertaining guests was a bit troublesome.

Because today's guest is indeed a little special.

Liu Deben came, Wu Congxin came, and Lu Ruoxi also came.

Their arrival made the house more lively.

However, the appearance of Lu Ruoxi made Liu Xiaoli feel a sense of crisis instantly, but she quickly greeted her as the hostess.

Especially when the little one called her mom, Liu Xiaoli smiled happily.

Even if she didn't see Lu Ruoxi's expression, she knew at this moment that Lu Ruoxi's face was definitely very wonderful.

Not to mention Lu Ruoxi, even Lu Yangui was a little surprised.

As a leader, Lu Yangui's facial expression management is still very good, but unexpectedly, today because of a call from the little guy Wang Junhong, his facial expression management got out of control.

After the little episode, Lu Yangui took out red envelopes again, and even Wang Duoyu got one.

Sisters Wang Meihe and Wang Meili were curious about whether the red envelope given by the leader would be very big.

But they were too embarrassed to open it and look at it now, so they could only wait until after dinner.

In addition to Lu Yangui, Liu Deben and others also gave red envelopes. If you don’t know, you might think that the Spring Festival has not yet passed.

Tonight's meal is not very sumptuous, as several dishes are home-cooked, and only three dishes are bought from Qingyunlou.

How should I describe the atmosphere at the dinner table? It seemed harmonious and happy, but in fact it was not.

Liu Deben and his friends brought some alcohol, two bottles of Wuliangye, two bottles of Fenjiu, and two bottles of Moutai.

They brought a lot of wine, but Wang Duoyu didn't drink much. Instead, Lu Ruoxi drank quite a lot.

It seemed that he was drowning his sorrows in alcohol. Anyway, no one tried to persuade him. After all, his grandfather Lu Yangui didn't say anything, so Wang Duoyu and the others naturally couldn't say anything.

And since she was drinking by herself, everyone had to pretend not to see it.

After dinner, Lu Yangui did not make any more requests, just like he usually did when visiting someone else's home.

After the leaders left, sisters Wang Meihe and Wang Meili couldn't wait to take out the red envelopes and started opening them.

"Oh, it's actually ten dollars, so much?"

In this day and age, red envelopes only care about the meaning. Not to mention a ten-yuan red envelope, even a one-yuan red envelope is a lot.

You should know that the largest unit of paper money nowadays is ten yuan.

The fourth edition of RMB was only issued in 1987. Currently, the third edition of RMB is in circulation on the market, with the largest denomination being ten yuan.

When the little guy saw the money, he happily came forward to take it.

"You two sisters are really money-grubbers. Ten dollars makes you so happy?"

Wang Duoyu, who was standing next to him, said with a smile, and the two sisters immediately retorted:
"Of course. Ever since we got married, you haven't paid us any salary. How can we have any income?"

This is a fact, and to be precise, since Liu Xiaoli came back in April and May last year, it has been Liu Xiaoli who has been taking care of the little guy Wang Junhong more, and the two sisters have been focusing more on studying.

"Didn't I tell you that there is a golden house in books? You know that."

However, Wang Duoyu didn't buy their talk and instead told them with a smile about Want Want Group.

After the Spring Festival, although it was not yet the end of the first lunar month, the business of the Brabus Watch Factory had obviously increased a lot.

However, no matter how well Brabus watches sell, they are still not as good as a fraction of Uma clothing. Why?
Because Yuma clothing is sold out overseas.

Before the Spring Festival, Zheng Baoyin shipped a large number of Youma clothing through the shipping company under Lotte Group.

At that time, a contract was signed with the new distributor Balde Duke, and the original plan was to ship out 300,000 pieces of clothing, plus an additional 200,000 pieces, as well as Balde Duke's 100,000 pieces of clothing were packed and shipped to San Francisco.

But even with so much stock, it was sold out before March.

There is a saying that there is no harm without comparison.

The price of Uma clothing on the shelves of companies like Sears is as high as $49, but the price in Uma clothing stores is $29.9 or $39.9.

The price difference is simply too outrageous.

Therefore, after learning about Youma Clothing’s own store, many consumers rushed to the store to make purchases.

Actually, it’s just clothes, not that popular.

But the problem is that Youma Clothing will definitely advertise, otherwise it will not attract many customers just by shouting.

Just use methods such as discounts for the opening of a new store.

The retail price at Sears and other department stores is $49. The Uma self-operated store is a new store opening, so it is selling at a discount. Isn't that normal?
They used all kinds of methods, including placing a loud speaker at the door, and playing music all the time during business hours.

At first, people from the store next door came to complain, but until it attracted many customers to come and watch, and the business of several surrounding stores gradually improved, the complaints stopped.

Therefore, under such circumstances, Youma clothing was exported and sold extremely well.

With 500,000 pieces of clothing and an average price of US$34.9, the revenue is US$17.45 million.

In just over a month, so many goods were sold and the revenue was nearly 20 million US dollars.

Horror!
No, they are just clothes with relatively novel designs, but the average selling price has reached US$34.9. Isn’t this price expensive?
There are really a lot of rich people!

Is it because the interest rates on US dollar deposits were high in the past two years and many people made money?

In 1980 and 1981, due to the high inflation rate caused by the oil crisis, the deposit interest rates in these two years were 12% and 16.39% respectively.

Since the deposit interest rate is so high, everyone can make money just by depositing money in the bank.

Commonly known as making money while doing nothing!

But in reality, it’s not that simple.

Regardless of whether ordinary Americans make money or not, Youma Clothing is definitely making a lot of money by going overseas.

Clothing is a traditional industry, how can it make so much money?

Of course, it is not Uma America that makes money, but Uma China, after all, these are two different companies.

The cost price of Yuma clothing exported from China to the United States is higher than that of distributors.

Currently, dealers have two prices, one is a package price of US$5.9, and the other is US$6.9.

According to their retail prices in the United States, one is $49 and the other is $59.

I don’t know how long they can hold on, but anyway, this is nine times the profit, so the dealers will definitely be able to make money, right?
"Brother Jiu, that's you making money, not us."

After hearing what their ninth brother said, Wang Meihe and her sister rolled their eyes and complained.

"Yes, sister is right, it's you who earns the money. Besides, you earn so much money, don't you know how to pay your lovely sister a salary?"

Wang Duoyu said: "Pay you a salary? Let you spend money lavishly? And then let you make me angry again? Then I might as well buy some books, food or something. Even if I donate them to others, it is much better than being angry with you."

"No, brother, I was wrong. It's Chinese New Year now, can't we just let this go?"

After chatting for a while, today's "quarrel" was finally over.

Liu Xiaoli was listening beside him without interrupting.

In the evening, Liu Xiaoli was unusually gentle. She did not mention Lu Ruoxi at all, because Wang Junhong's call of "Mom" had already proved everything for her.

It doesn’t matter what Lu Ruoxi thinks. What matters is that Wang Duoyu values ​​her and his son very much, and that’s enough.

You know, even Zhu Ling stayed from the beginning of the year to after the Spring Festival, but she still couldn't succeed, and finally ran away to the crew in disgrace. Lu Ruoxi was even less competitive. Hugging Wang Duoyu, Liu Xiaoli thought about what she had done before, and she also felt that she was really confused at that time. Why did she break up with Wang Duoyu?

Zhu Ling is really confused now. Why was she so stupid to divorce Wang Duoyu?
In the history of the original time and space, Zhu Ling was actually also obsessed with looks. When filming Journey to the West, she seemed to have really put herself in the role of the Queen of the Kingdom of Women and fell in love with Tang Monk at first sight.

But Tang Seng was naturally not confused, he still went to the West to obtain the scriptures.

But, menstruation is also menstruation, why do we have to go to the West to get it? Can't we just stay in the Kingdom of Women?
Of course, in this time and space, Zhu Ling’s favorite Tang Monk is Wang Duoyu, and he also did not stay in the Kingdom of Women.

"Duoyu, you said there's nothing wrong with our bodies, so why can't we get pregnant?"

After finishing the fill-in-the-blank questions, Liu Xiaoli couldn't help but ask.

She is still doing a handstand because today is her ovulation period. She has to persist. She should be able to get pregnant this time, right?
Wang Duoyu, who was standing next to him, got up and went to the next room to take a look at the little guy. Seeing that the little brat was sleeping soundly, he came back.

"Could it be that your mindset is the problem? Keep a calm mindset and don't be too obsessed. Sometimes surprises will come as expected."

"Why can't I calm down? What you said doesn't make any sense at all."

Liu Xiaoli argued, but Wang Duoyu did not argue with her. He asked her to stand there for a while and go wash up quickly. He had to go back to look after the child first.

Every time the two of them did the fill-in-the-blank questions, they had to wait until the little one fell asleep, and they had to get up carefully and go to the next room to do the questions. They had to be careful during the process, because if the little one woke up, it would be troublesome.

"Go ahead." Liu Xiaoli said impatiently.

At 1:30 p.m. the next day, another notice was posted on the bulletin board of the Department of Mathematics teaching building, announcing that the monthly mathematics sharing session had been moved to the auditorium.

Why do we have to move to the auditorium?

Because there are too many people in the tiered classroom now, many people have already gone there to grab seats before even having lunch.

The broadcast also sounded at the same time, and the teacher in the tiered classroom specifically notified everyone to move to the auditorium.

School has just started, how come it has turned out like this?
There was no monthly sharing in February because before the New Year, Wang Duoyu had already discussed the geometric Langlands conjecture twice with Shing-Tung Yau and others.

In addition, Wang Duoyu himself was very busy, so the plan was changed to after the Spring Festival.

After the Spring Festival, Wang Duoyu became even busier.

After being postponed again and again, finally in early March, just a few days ago, Su Zhenghuai arranged a notice for the monthly sharing on March 6th today.

Since the announcement was posted several days in advance and there had been no sharing for more than a month, there were a lot of people.

Of course, the main reason is that more and more people have come to Harbin Institute of Technology recently.

Edward Witten, a physics professor who came from abroad, has crossed over, and there are even more masters and doctors from the mathematics field.

No one doesn't want to listen to Wang Duoyu's lectures, simply because the papers of Yang Nianzhen and other seven disciples have been published and everyone can see them. Who doesn't want to be the next Maxim?

However, is it really that simple?
Many people lack talent and try hard to make up for it, but it still remains difficult.

Everyone hopes to receive personal instruction from Wang Duoyu, but unfortunately he has never taught basic courses, so it is not possible to audit the course.

Therefore, even the monthly math sharing sessions attract them.

The depth of the content in each monthly math sharing session varies because the difficulty levels of the questions raised by everyone are different.

Therefore, as long as I still hope to go further in mathematics, I will continue to attend classes.

Of course, it is now March 1983, and the visiting scholar exchange group that started at the end of 1980 has been going on for two years and two months.

The previous masters are almost graduated, and the PhDs should have found jobs.

Masters and doctoral degrees in this era are elite education, and graduation will not take five, six, seven or eight years.

Some of these foreigners who have graduated have left Harbin Institute of Technology, but a considerable number of them have stayed at Harbin Institute of Technology, either entering the Ice City Institute for Advanced Study or working in the field of applied mathematics.

However, there are still more people coming to Harbin Institute of Technology, and those who have not given up on mathematics still want to continue to make progress.

After all, whether it is Harbin Institute of Technology or Ice City Institute of Advanced Studies, if you want to get a salary increase, you need to have scientific research results.

So how can you make yourself progress faster?
Edward Witten, who was sitting in the second row of the auditorium, has given the answer based on his personal experience: attending Wang Duoyu's class is one of the shortcuts to progress.

When Wang Duoyu walked into the auditorium, quite a few people had already arrived.

The entire auditorium was not full, but more than 70% of the seats were occupied.

The auditorium can accommodate 3,000 people, and the occupancy rate is about 70%, which means there are just over 2,000 people.

It’s not a lot, but it’s definitely not a small amount.

Today is another long sharing time!
After just a glance, Wang Duoyu was almost certain of this; his guesses were never wrong.

As it turned out, his guess was correct.

The sharing started at 2 pm and it was not over until 6:30 pm.

From the mathematical branches of pure mathematics such as number theory, algebraic geometry, topology, and then to string theory, topological quantum, mirror symmetry, etc. related to physical mathematics.

Because it's not just Edward Witten who is a professor of physics, there are also many related physics masters and doctors, and they all have their own problems.

Such communication is also very beneficial to Wang Duoyu himself.

At the very least, his understanding of general relativity, quantum mechanics and other related theories has become deeper.

Wang Duoyu never underestimates these masters and doctoral students, no matter whether they are pure mathematics researchers or not. As long as they have really thought about their problems seriously, then when they ask questions, they have already made it clear that they really cannot answer these questions.

In the mathematical community, genius is highly admired.

Mathematics is called the language of God and has a profound impact on various disciplines, especially physics.

In the media, Wang Duoyu is called the Emperor of Mathematics, but he never thinks too highly of himself because there is never a shortage of geniuses in mathematics.

For example, Gauss, the prince of mathematics, learned high school mathematics in just one afternoon, which many people would need three years to complete.

No one can guarantee that among the crowd listening to his sharing in the auditorium, there will not be a mathematical genius who suddenly has an epiphany and then ask him a very difficult mathematical problem.

For example, when John von Neumann, a top genius, was attending a party, the hostess of the party suddenly decided to test the top mathematician John von Neumann.

The question is: Two trains are one mile apart and moving towards each other at a speed of thirty miles per hour. At the same time, there is a fly on one train flying towards the other train at a speed of sixty miles per hour.

When the fly flew to another train, it quickly flew back.

It kept flying back and forth like this until the train collided.

Question: How many miles did the fly fly in total?
In fact, this question is a mathematical problem of summing infinite numbers. Most people calculate the flight distance of the fly again and again, and then add up the results.

Although it is not difficult, it is time-consuming and laborious.

However, there is a trick to this problem. First, calculate how long it will take for the two trains to collide. This is easy to calculate, which is 1 minute.

And a fly flies at sixty miles an hour, one mile a minute, so it's easy to conclude that the answer is one mile.

But as soon as the hostess finished asking the question, von Neumann answered almost simultaneously: 1 mile.

"I'm surprised you figured it out so quickly," the hostess said. "Most mathematicians don't see the trick here and use infinite numbers, which takes them a long time to figure out."

Von Neumann: "What trick? I also use infinite numbers."

This is the brain of a top mathematician. They work very fast, comparable to a computer.

This seemingly difficult problem can be solved instantly by a computer that can perform 2,000 or 10,000 operations per second.

However, in real scientific research projects, there are too many mathematical problems that require repeated calculations, and even problems involving fields such as topological quantum and algebraic geometry.

When the Poincaré conjecture was first proposed, why did no one solve it for over half a century? Was it because there weren't that many top mathematicians at the time?

No, it’s because the problem is too difficult. Even Henri Poincaré, the leading mathematical genius in the second quarter of the 19th century and the early 20th century, could not solve it, let alone others?

This is why the mathematical community worships genius so much.

Because there are talented people in every generation, and each of them leads the trend for hundreds of years.

Wang Duoyu himself has questions that he cannot answer. If someone in the auditorium raises a question related to the strong solution of the Navier-Stokes equations, he may not be able to solve it?

As we all know, the strong solution of the Navier-Stokes equations is a problem that is currently involved in various fields such as mathematics, physics, and engineering. In particular, the aerospace field needs to solve this problem urgently.

If this can be deduced, then humans may be invincible in the atmosphere.

Take the ramjet engine as an example. This thing is the king of engines in the atmosphere. It has no moving parts such as turbines and compressors. It uses the forward motion of the aircraft to compress the air and then drive the engine to work.

Ramjets typically propel at speeds between Mach 3 and Mach 6, or even higher.

Its working principle is also very simple and can be understood by a second grader.

Let's first briefly review how a turbofan engine works. After air is drawn into the engine, the compressor compresses it greatly, significantly increasing the pressure.

Then the high-pressure air enters the combustion chamber, mixes with the injected fuel and is ignited. The intense combustion produces high-temperature and high-pressure combustion gas. Finally, this high-temperature and high-pressure combustion gas enters the turbine, and the expansion of the combustion gas drives the turbine blades to rotate.

The rotating turbine shaft drives the rotation of the fan and compressor blades, thereby maintaining the continuous progress of the entire compression and combustion process.

The upper speed limit of this turbofan engine is between Mach 2 and 3. For example, the Concorde technology can reach a maximum flight speed of Mach 2.04.

However, when the Concorde's flight speed reached Mach 3, the air flow rate entering the engine was too fast, and the traditional compressor was naturally unable to effectively compress these high-speed airflows. The air compression efficiency would drop rapidly, and the high-temperature and high-pressure airflow would also damage the turbine and compressor components.

So, the ramjet engine came into being.

Without the compressor, there is no need for the turbine.

At this time, when the aircraft is flying at high speed, the oncoming airflow is faster. When passing through the air intake at the front of the aircraft, the airflow will be naturally compressed, generating higher pressure and temperature. This is the ramjet effect.

Also known as a ramjet engine.

In fact, this concept was proposed and patented by French engineer René Laolin as early as 1913.

The Mach 5 fighter jet proposed by Wang Duoyu previously uses such a ramjet engine design and utilizes subsonic ramjet engine technology.

This subsonic ramjet engine technology is mature and suitable for medium- and high-speed flight at Mach 3 to 5, such as the medium- and high-speed anti-ship missiles and cruise missiles that have been developed.

It’s just that the sub-combustion ramjet engine technology has not yet been applied to fighter jets, and it will not be applied even in the future.

In this time and space, Wang Duoyu wants to give it a try.

No matter it is ten or twenty years, people still need to have dreams. What if they come true?

Of course, the technology sounds simple, but in fact, the mathematical problems involved are very large and complex.

This is one of the reasons why Wang Duoyu has always been humble.

At this moment, almost everyone in the auditorium was once called a mathematical genius, but some people were only called that by their classmates, while some were called geniuses by their peers in the mathematics community. For example, Wang Duoyu is now recognized as the Emperor of Mathematics by the global mathematics community.

Even so, Wang Duoyu was afraid that someone in the audience would ask a question related to the strong solution of the Navier-Stokes equations.

At 6:50 in the evening, today's sharing finally came to an end.

But the people in the audience were still not satisfied.

Edward Witten, in particular, listened very carefully, afraid of missing any details.

In fact, during Wang Duoyu's sharing, there were many theories of mathematical branches, which Edward Witten didn't quite understand, but he still listened with great interest.

One of the hottest topics in mathematics right now is the grand unified theory: the Langlands program.

This theory involves three branches of mathematics: number theory, algebraic geometry, and group representation theory.

Edward Witten also didn't know whether these theories would have an impact on his research on string theory, such as giving him some associations or inspiration.

So he would listen as much as possible and try to understand.

While everyone was still savoring the moment, Wang Duoyu had already strode out of the auditorium and hurried to the bathroom.

He went to the bathroom once in the middle, otherwise his bladder would definitely not be able to bear it for more than four hours, almost five hours.

After coming out of the bathroom, Wang Duoyu prepared to go home for dinner. It was finally over, so he naturally wanted to relax and rest.

But at this time, Charles Fefferman, John Milnor and others were already waiting.

"Professor Wang, let's go. I've already booked a private room in the school cafeteria. You definitely can't refuse today, right?"

Wang Duoyu couldn't help but smile bitterly when he heard this.

He rejected the other party yesterday, but he didn't expect that the other party would come to block him again today.

So he had no choice but to tell Su Zhenghuai and ask him to help call home and inform them that he would be back later.

In the small private room of the Harbin Institute of Technology cafeteria, there are quite a lot of guests today, or to be more precise, there are several new people.

Edward Witten came, and so did Daniel Gray and Joseph Cohen.

The latter two are also Fields Medal winners. They came to Harbin Institute of Technology at the beginning of the month, just a few days earlier than Edward Witten.

"welcome!"

At the dinner table, Wang Duoyu raised his glass and spoke to Daniel Gray, Edward Witten, Joseph Cohen and others.

The United States is indeed a beacon of freedom. These Fields Medal winners, more than six in number, have all come to Harbin Institute of Technology.

In addition, future Fields Medal favorites such as Shing-Tung Yau, Edward Witten, Vaughan Jones, and Jean Bourgain are also studying at Harbin Institute of Technology.

It can be said that the reason why the Department of Mathematics at Harbin Institute of Technology was able to grow, in addition to relying on Wang Duoyu's unparalleled mathematical talent, was more because it poached talents from the American mathematics community.

Of course, now is the stage of mutual game. It depends on whether Harbin Institute of Technology will grow up completely in the end, or Wang Duoyu will be forced to go to the United States.

"Thank you!"

Daniel Gray and his group were very happy and raised their glasses to drink.

After they arrived at Harbin Institute of Technology, they did not immediately feel how good the mathematical atmosphere here was, but were conquered by the delicious food here.

In order to keep these foreigners, Wang Duoyu tried every possible means. Although they were all open conspiracies, everyone couldn't help but get deeply involved in them.

Who doesn’t know that Wang Duoyu is awesome?
Princeton University, Harvard University, Massachusetts Institute of Technology, University of California, Berkeley and other universities have all invited Wang Duoyu to give lectures, conduct visiting studies, serve as a professor at their schools, and have offered him very high salaries.

Especially after Maxim published his third paper, the salary offered to Wang Duoyu became even higher.

However, Wang Duoyu still did not go.

Therefore, while Wang Duoyu was still staying at Harbin Institute of Technology, other places certainly couldn't sit still either.

Since Wang Duoyu is very strict in accepting disciples, it would be a good idea to go and attend his classes.

They knew that these were all open conspiracies, but even smart people like Edward Witten, Daniel Gray, and John Milnor couldn't help themselves, which is enough to show the charm of Wang Duoyu.

After arriving at Harbin Institute of Technology, I realized that the food here is so amazing. It was another conspiracy, because the food became one of the reasons for them to stay in Harbin Institute of Technology.

After everyone had a glass of wine, the topic started with food, and the atmosphere of conversation at the table immediately opened up.

After the lively conversation, the private room suddenly became quiet after Charles Fefman suddenly mentioned the topic of the International Congress of Mathematicians that was about to take place this summer.

Everyone pricked up their ears and looked at Wang Duoyu, wanting to see what he thought about this.

This year's International Congress of Mathematicians will certainly be extraordinary and destined to go down in history.

Wang Duoyu, a hot favorite for the Fields Medal, has four major scientific research achievements, namely the Poincare-Smale-Wang Duoyu Theorem, Fermat's Last Theorem, the ABC Theorem and the Honeycomb Theorem, as well as some other second-rate mathematical papers, which are of great value.

So will he go to Warsaw to receive the award in person?
