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

Chapter 147: Wailing all over the place, the youngest professor in the history of Harbin Institute of Technology

June 20, 1979, Office of the Director of the Department of Mathematics, Peking University.

"Director Feng, I really don't have anyone here. It's no use for you to come to me. Everyone is busy."

Duan Xuefu looked at Feng Kang in front of him with helplessness. The latter came to Peking University again today, hoping that the former could help and send some people.

The main reason was that the Computing Center was short of staff recently and the project was urgent. Feng Kang was forced into a corner and had to come to Peking University to ask for help.

"Director Duan, I know you have a solution."

The two men talked incoherently for a while. At this time, the phone on the desk rang. Duan Xuefu was overjoyed because he urgently needed an excuse to drive Feng Kang away.

The phone ringing is a perfect excuse.

Feng Kang had no choice but to look back at Duan Xuefu every few steps, but the latter waited until the other party walked out of the office before answering the phone.

"Director Duan, the latest news just came from Harbin Institute of Technology. Wang Duoyu has proved the Poincare conjecture in three-dimensional space. The paper has been sent to the post office for delivery to Beijing. It should be delivered tonight."

After Hua Luogeng sent out the three papers through a phone call, the post office immediately arranged for someone to put the papers on the plane and arrive in Beijing on the same day's flight.

This is the paper on the Poincaré conjecture, which is extremely important, so Hua Luogeng must see this paper first.

At the same time, in order to review the three papers more quickly, Duan Xuefu and others received calls from the Institute of Mathematics, and all those who received the calls gathered at the Institute of Mathematics of the Chinese Academy of Sciences.

"Okay, I understand. I will be there on time."

After the phone was hung up, Duan Xuefu's expression instantly became complicated, with joy, frown, confusion and other emotions all appearing.

The reason was simple: he was worried that this time his excitement would be in vain.

A few days ago, Kunal from India announced that he had proved the Poincare conjecture in three-dimensional space, although the correctness of his paper has not yet been verified.

However, Duan Xuefu was very worried that Wang Duoyu might have been influenced by Kunale, so he had to publish the paper in advance.

What Duan Xuefu was worried about was that Wang Duoyu was upset!

In fact, up to now, we have not received any news from Shing-Tung Yau, Smale, John Milnor and others. This is the best news.

As for Kunale, to be honest, Duan Xuefu didn't think he was a threat.

Unlike Duan Xuefu who was full of worry, Tao Fangqi's face was full of ecstasy.

Because he has full confidence in Wang Duoyu, it can be said that he is the only person who has the most confidence in Wang Duoyu, and this confidence even exceeds that of Wang Duoyu himself.

At 6:20 in the evening, a car stopped steadily in front of the Institute of Mathematics.

Soon, three papers airlifted from Ice City were delivered to the office. Hua Luogeng, Chen Jingrun, Tao Fangqi, Lu Qikeng and others were all there.

In addition, Cheng Minde, Zhao Fangxiong, Wu Wenjun and others all came closer.

The paper is first printed in multiple copies and then distributed to others.

By eight o'clock in the evening, everyone in the Institute of Mathematics had three papers, and the review work began at this time.

In fact, the people most suitable to review Wang Duoyu's three papers were not Hua Luogeng and others, but Qiu Chengtong, Smale and others.

But Shing-Tung Yau and his colleagues are now in the United States, not in China, so they can only wait.

However, although Shing-Tung Yau was not there, his teacher Shiing-Shen Chern was in China. In the afternoon, Chern also received the news and immediately rushed back from Nankai University in a hurry. He must have wanted to see these three papers first.

At nine o'clock in the evening, a transatlantic call was made from Hong Kong Island and successfully connected to the University of California, Berkeley in Berkeley, California, USA.

Qiu Chengtong was reading a book at home. When he heard the voice of his wife Guo Youyun, he realized that someone had called him.

"It's a call from the Fok family in Hong Kong Island."

Qiu Chengtong nodded to his wife, and after answering the phone, he realized that the person on the other end was not Henry Fok, but Yang Zongli from China Resources Company.

"Leader Yang, are you saying that Wang Duoyu has proven the Poincaré conjecture in three-dimensional space? Three papers in total? What mathematical tools did he use? Are they innovative geometric tools? What is the structure of submanifolds? What is the Riemann metric?"

When Yang Zongli heard what Qiu Chengtong said, his eyes widened.

How could he understand this?

What about submanifolds and Riemannian metrics? How does he know about these things?
"Professor Qiu, I really don't know this. I only heard the news from the mainland. Harbin Institute of Technology sent the three papers through the post office this morning. I just spoke on the phone and they confirmed that the three papers have been delivered to the Institute of Mathematics of the Chinese Academy of Sciences in Beijing."

Yang Zongli hurriedly said:
"At the same time, the other three English versions of the papers are already on their way to Hong Kong Island. Once they arrive, I will arrange for someone to deliver them to Professor Qiu's residence as quickly as possible. Professor Qiu, please help review them."

Upon hearing this, Qiu Chengtong nodded happily in agreement.

This is a good thing, and he is even looking forward to seeing the three papers.

After he hung up the phone and shared the news with his wife Guo Youyun, he heard his wife ask:
"Someone else has already proved the Poincare conjecture in three-dimensional space before you, why are you still so happy?"

"Why shouldn't I be happy? You know, the Poincare conjecture has troubled our global mathematics community for over half a century. Now that we've solved this problem, I should be happy."

Regarding this, Shing-Tung Yau is not jealous of Wang Duoyu, after all, the latter is a very talented person.

"Although judging from the current situation, I am indeed not as good as Wang Duoyu, but you should know that I became famous very late. I am indeed a late bloomer. Wang Duoyu is a young genius. This is his era."

"As for other aspects, I don't think I'm inferior to him. I can only say that I'm more familiar with the Poincaré conjecture than he is, that's all."

As a genius in the field of mathematics, Shing-Tung Yau was definitely not as relaxed and free of pressure as he says now.

One thing that is undeniable is that Wang Duoyu is very outstanding and young.

But it is certainly impossible to say that Qiu Chengtong is jealous of Wang Duoyu.

Not to mention anything else, just because Wang Duoyu was unwilling to study in the United States, he knew that the other party would never be able to live a good life.

At the very least, in terms of material enjoyment, Wang Duoyu will never be able to compare with him.

As for his wife, haha, Zhu Ling's appearance is indeed unparalleled in the world, but she is just an ordinary person. Even at the academic lecture at Peking University, she showed impatience and other attitudes. She has no vision and is not the kind of wife an academic researcher should marry.

On the contrary, Qiu Chengtong married Guo Youyun, a physicist from Taiwan. She is an excellent choice in terms of knowledge, vision and insight.

Therefore, in Qiu Chengtong's view, except for the fact that Wang Duoyu might be slightly better than him in mathematical talent, he is crushed by him in other aspects.

Seeing this, Guo Youyun knew what her husband was thinking, so she curiously asked about Wang Duoyu.

As a result, just this one sentence made Qiu Chengtong feel unhappy.

After all, no matter which man he is, he wouldn't want his wife to ask about a strange man, right?

Qiu Chengtong is relatively generous in other aspects, but he is much more stingy when it comes to love.

The next day, in the public office, Qiu Chengtong met Smale and told him that Wang Duoyu had verified the Poincare conjecture in three-dimensional space, and that the paper was on its way to Berkeley.

"Oh my God, this is unbelievable. Professor Qiu, are you telling the truth?"

Smel immediately asked with a look of amazement on his face. Although he said asking, he actually believed in his heart that it was true.

why?
Because this is Wang Duoyu, not the Indian doctoral student.

Kunale, a doctoral student at the Indian Institute of Technology, was quite capable. When he announced that he had proved the Poincaré conjecture in three-dimensional space, Smale could only marvel at it before seeing the paper.

But if it was Wang Duoyu, Smel had already vaguely believed it.

You know, when he was in Beijing in April, he had discussed the proof tools of three-dimensional space with Wang Duoyu more than once.

Not only did Shing-Tung Yau propose tools for Ricci flow, but Wang Duoyu also proposed a method of using geometric tools to cut three-dimensional space. These are very mature methods that have the potential to prove the three-dimensional Poincaré conjecture.

In addition, Wang Duoyu was young and had a very good brain, so Smale was more willing to believe that he had proved the Poincare conjecture in three-dimensional space.

"It must be true. They wouldn't play such a joke on me. We'll be able to see the paper in a few days."

Qiu Chengtong responded with a smile. He expected Smale to be so excited.

Just then, the phone on his desk rang.

"Professor Qiu, we have received the three English-language papers. They were delivered to a Japan Airlines flight an hour ago."

The call was from Yang Zongli, who informed the flight number and other relevant information, which made Qiu Chengtong very happy.

In this era, traveling from Hong Kong Island to the United States requires transferring in Tokyo and then flying to San Francisco.

Otherwise, it would be taking an international cruise.

But international cruises take very long, taking at least ten days to half a month to reach the United States, so rich people will choose to fly, and if they don’t have money, they can only choose a cruise.

"OK, thanks!"

Qiu Chengtong smiled and said thank you. When Smale saw him hang up the phone, he couldn't wait to ask more questions.

Smale was even happier when he learned that the paper was on its way to the United States.

Two days later, the paper was successfully delivered to Shing-Tung Yau, and Smale and others could not wait any longer.

The three papers were reprinted, the printed papers were kept, and the originals were sent back to the Annals of Mathematics.

Victor King, who was far away in the small town of Princeton, was surprised and incredulous when he received a call from Shing-Tung Yau.

Unlike Kunale a few days ago, Wang Duoyu's paper came really quickly.

Moreover, Wang Duoyu was very confident, which also caused some doubts in Victor King's heart.

He had just finished an academic report conference last year after proving the Poincaré conjecture in four-dimensional space until April this year. Unexpectedly, only two months later, Wang Duoyu announced that he had proved the Poincaré conjecture in three-dimensional space. This is incredible!
No matter what Victor King thinks, the matter is done. As the editor-in-chief of the "Annals of Mathematics", his job is to find relevant reviewers to complete the review of the three papers submitted by Wang Duoyu.

This time the letter was sent by Shing-Tung Yau, so there was no need to notify both Yau and Smale.

But before Victor King received the airmail document, Andre Weil, John Milnor, Charles Fefferman and others all called him to ask about Wang Duoyu's latest paper.

People like Andre Weil are either professors at the Institute for Advanced Study in Princeton or at Princeton University.

As one of the only two mathematics centers in the world, Princeton University certainly has a very profound foundation.

John Milnor won the Fields Medal in 1962, Andre Weil proved the Riemann hypothesis for all curves and proposed the Weil conjecture, and Charles Feifman is the same age as Shing-Tung Yau, but he won the Fields Medal last year.

Therefore, Princeton, the center of mathematics in the United States, has produced a large number of top mathematicians, both from the old generation and the middle-aged and young generations.

Wang Duoyu proved the Poincare conjecture in three-dimensional space, which was a very shocking thing to André Weil and others.

Between Wang Duoyu and Kunale, Andre Wei and others would definitely choose to believe the former.

As to whether Kunal, a doctoral student at the Indian Institute of Technology, is a clown, only time will tell.

Anyway, John Milnor and the others didn't care too much about these trivial matters. Instead, they were more eager to know whether Wang Duoyu's paper had really been verified.

At the Institute for Advanced Study in Princeton, Michael Friedman, a 28-year-old researcher, turned pale when he heard from André Weil today that Wang Duoyu had proved the Poincare conjecture in three-dimensional space.

Because he is one of the people who studies the Poincare conjecture!

If Wang Duoyu really proves the Poincare conjecture in three-dimensional space, then all his efforts over the past years will be in vain.

He also has to change the direction of his research topic as soon as possible, otherwise his promotion to professor will continue to be delayed.

"Andre, can I apply to join the review team?"

"Can't!"

Andrei Weil shook his head and refused without hesitation. Although the matter should be explained by Victor King, the editor-in-chief of the "Annals of Mathematics", those who can participate in the paper review must be at the professor level, and even must be experts in this field.

Michael Friedman is just an associate professor, and was only promoted this year, so he definitely doesn't meet the requirements.

Michael Friedman was extremely disappointed and had no choice but to calm down and seize the time to change the direction of his scientific research topic.

As time passed, many people received relevant rumors and learned that Wang Duoyu had proved the Poincare conjecture in three-dimensional space and might even have completed the ceiling. When they completely proved the Poincare conjecture, some mathematics doctors and professors felt like the sky had fallen.

Many people, like Michael Friedman, are researchers on the Poincaré conjecture.

Because the Poincaré conjecture has been one of the hottest topics in mathematics over the past decade. It was all because Smale proved the Poincaré conjecture for five-dimensional space and above more than five dimensions more than ten years ago, which made this topic even more popular.

Everyone likes to choose popular topics to research, and now they are suffering.

From the University of California to Stanford University, to MIT, and finally to Harvard University and Princeton University, the mathematics departments of these schools are in a state of mourning.

People with relevant connections contacted Victor King, the editor-in-chief of the Annals of Mathematics, to verify whether the news was true.

Unfortunately, Victor King didn’t know either, because after the paper came into his hands, it was quickly snatched away by professors such as Andrei Weil.

Even if he still had the printout in his hand, it would be useless because he was only the editor-in-chief and had no way of reviewing the specific results.

Only top mathematicians can clearly prove top-level problems like the Poincaré conjecture. For others, it would be great if they can understand the paper.

Institute of Technology, New Delhi, India.

Kunale was still immersed in joy when Lahar came to him one day with a telegram from the United States:
"Kunale, news has come from the United States that a Chinese mathematical genius has proved the Poincaré conjecture. Three papers have been submitted to the Annals of Mathematics and are currently under review by top mathematicians such as Shing-Tung Yau and Smale."

What this means is that the genius Wang Duoyu in the Chinese mathematics community is the real master, and he has already proved the Poincare conjecture.

So the paper Kunale submitted earlier was nothing more than a scam.

"Humph, he must be faking it. How could he have proved the Poincare conjecture so quickly?" Kunale snorted grimly.

But at this time, Kunale received a call from his mentor, Professor Galeva, who said that his friend in the United States had received a notice from the Journal of the American Mathematical Society that the proof paper Kunale submitted earlier was not approved.

The Journal of the American Mathematical Society is a very rigorous journal. Since it was not approved after review, it means that Kunale's proof paper is fake.

Even if it is not fake, it has no academic value and will not be published.

Kunal hung up the phone in a daze. He didn't know when Rahal left.

Under the current circumstances, I am afraid that even his doctoral graduation may be affected.

The American media did not pay attention to this incident. Instead, several tabloids in Hong Kong reported on it because they like this kind of news.

Recently, due to the academic conference held at Peking University, many people have paid special attention to news in the mathematics community.

Especially since Wang Duoyu, a mainland mathematical genius, wrote a new paper, the media are all reporting on it, and tabloids will naturally look for such hot news to increase sales.

It’s no wonder that the news about an Indian mathematics PhD becoming a clown is still very popular.

Because it was also an event related to the Poincaré conjecture, an Indian mathematics doctor was the first to inform the world that he had proved the Poincaré conjecture in three-dimensional space.

The results were confirmed by the Journal of the American Mathematical Society and the paper failed to pass review.

On the contrary, although there has been no news about Wang Duoyu’s three papers since they were released on June 22nd to early July, no news is the best news.

With the ability of Shing-Tung Yau and others, they must have reviewed one of the three papers in such a long time, right?
If the paper is not good, it will definitely be discussed.

Amidst the turmoil outside, mathematics professors like Shing-Tung Yau and Smale closed their doors to visitors and focused on reviewing Wang Duoyu's paper. Meanwhile, Wang Duoyu was being taken hunting in the mountains by Yuan Jigang and his team.

On June 20th, after Wang Duoyu sent out his paper, he returned to the office of the Department of Computational Mathematics. In the afternoon, he made an appointment with Yuan Jigang and others to play football together.

The next day they all came to his house for dinner, and during the process, they saw the bullet that Wang Duoyu had not hidden.

A total of three hundred bullets! Yuan Jigang and the others' eyes lit up.

After some "friendly exchanges", Yuan Jigang and his friends learned from Wang Duoyu that these bullets were obtained from a leader, so they encouraged him to get some more bullets so that they could go hunting during the summer vacation.

Of course, Wang Duoyu didn't continue to ask for bullets. Three hundred rounds should be enough for a while anyway.

So, after Yuan Jigang and his classmates finished their final exams, a group of people set out to hunt in Wang Duoyu's hometown.

On the afternoon of July 8, Wang Duoyu and his group finally came out of the mountains after firing 200 rounds of bullets.

The results of this hunting trip were not as expected. Only two wild boars were hunted, nothing else.

No hares, goats, pheasants, etc. were hunted.

Of course, having two little wild boars is pretty good, after all, we didn’t return empty-handed.

In Dahonggou Village, at Wang Duoyu's house at the end of the village, Zhu Hanting looked at the busy construction site not far away with envy on his face.

"Duoyu, how long will it take to build this house? We've been in the mountains for two days, and there's been no progress."

Wang Duoyu heard this, glanced at Zhu Hanting, and was about to answer him when Yuan Jigang spoke first:

"Old Zhu, don't think too much. You're going to study in the United States soon. You won't be able to see the house until four years later."

Although the final exam results have not yet come out, Yuan Jigang does not think that Zhu Hanting cannot study in the United States.

There are not many places for studying in the United States in the entire Harbin Institute of Technology, but Zhu Hanting is still very strong, and he has published two papers in the "Acta Mathematica Sinica", one of which was published at the end of May.

With two papers and his usual grades, it would be no problem for Zhu Hanting to get a place to study abroad.

Jian Xianglan is a strong competitor of Zhu Hanting, but it is hard to say whether she can go abroad to study.

"Who says I can't come back until four years later? Can't I come back once a year?" Zhu Hanting raised his neck and said stubbornly.

Yuan Jigang curled his lips:

"Old Zhu, I'm not trying to discourage you, but you might not even be able to come up with the money for a round trip ticket."

This is true!
It is unlikely that the country will give so much money for studying in the United States at public expense. Besides, foreign exchange is very tight, so it is impossible for Zhu Hanting to come back to China once a year.

Unless Zhu Hanting himself is rich, but in a place like the United States, if you want to make money, you can only wash dishes.

But he was going to study abroad, not to wash dishes in the United States.

Besides, even if he went to wash dishes, how many dishes would he have to wash to earn enough money for a round-trip plane ticket to China?
Zhu Hanting was speechless after being confronted, so he turned around and didn't bother to pay attention to the other party.

Wang Duoyu smiled and shook his head:
"This is a pure wooden house, so it's definitely going to be time-consuming and laborious to build. Once all the wood is processed, we can start building the foundation. Anyway, it will definitely be finished before autumn this year."

The pure wooden house project started at the end of April, but it was not until mid-May that Wang Xiangdong and his team began to go into the mountains to cut down trees, and the trees were not transported out until June.

In other words, the Wang family is very large, with more than ten men between the ages of twenty and forty.

For example, Wang Xiangdong, Wang Duoshi, Wang Jianchao, etc. If Zheng Baoyin, Xu Quanhua and others are included, the number will exceed fifteen.

They all live in their hometown, so the task of felling trees was naturally left to them.

The wood began to be pre-processed in early June, and now it is July 8th, only a month has passed. Of course, the construction of the wooden house cannot be started so soon.

As we all know, the drying process of wood usually takes more than six months. If it is softwood, such as pine, spruce, etc., it often only takes two or three months.

In the back mountain of Wang Duoyu's hometown, there are many kinds of wood suitable for building wooden houses, such as red pine, larch, Chinese larch, walnut, linden, elm and birch, etc.

Since Wang Duoyu hopes to move in smoothly this year, the wood he chose is all pine.

These pine trees, such as red pine, are very straight trees. After being transported back, they can be peeled and dried in the sun.

Construction can begin in mid-to-late August.

If the wood still does not meet the construction standards by then, we can wait until September to build it.

Anyway, the materials must be prepared in advance, otherwise, if the construction period is delayed, it will be troublesome.

"Actually, I have a question. Aren't you afraid of freezing to death when winter comes?"

Lou Jianguo couldn't help but ask a question, and Yu Xinyao and the others all looked at him curiously when they heard it.

Even Yuan Jigang, a northerner, didn't know whether he would freeze to death in the winter if the house was made entirely of wood.

"Of course not. What is the brain used for? Can't you think of this?" Wang Duoyu said with a smile, pointing to his brain.

In the Northeast in winter, temperatures of minus thirty degrees Celsius are like playing. A breath can freeze into ice chips. Even if you wrap yourself in three layers of cotton jackets and trousers, you will still shiver with cold.

In the Northeast, heating is necessary for winter, but there are many ways to keep warm. The most common ways in rural areas are to burn kangs, stoves, fire walls, etc.

In the city, there is centralized heating, as well as electric heated kangs, electric fan heaters, electric heaters, floor heating, etc. in the future.

But now, in Dahonggou Village, the only ways are to use the kang and stove.

So of course these are the only heating methods Wang Duoyu can choose.

"Okay, it's good that you know this. I thought you hadn't thought of this."

Lou Jianguo’s explanation is worse than no explanation at all.

With Wang Duoyu's intelligence, how could he not have thought of this?
Lou Jianguo certainly doesn’t know as well as Wang Duoyu how cold the winter is in Northeast China. After all, the former only spent one winter in Northeast China, while Wang Duoyu has spent many winters.

"No matter whether it's warm or not, we'll find out when we come here to experience it in winter." Rong Guangxia suddenly said with a smile:

"By the way, Duoyu, when will the review of those three papers you wrote be completed? I still don't understand your paper on four-dimensional space. How about you give us a lesson while you have time?"

As soon as these words were spoken, Zhu Hanting, Yu Xinyao, Tian Maohua, Mo Ruogao and others all nodded happily and looked at Wang Duoyu expectantly.

Zhu Hanting and his colleagues know exactly how awesome the paper on the Poincaré conjecture in four-dimensional space is.

Even Lou Jianguo and others who were unable to attend the lecture at Peking University heard from Zhu Hanting and others how spectacular and shocking the scene was.

Therefore, studying this paper has become one of their tasks.

It’s just because they and Wang Duoyu are roommates, a friendship that no one else has.

"Another small class?"

Wang Duoyu shook his head helplessly and still didn't start the conversation.

Because even roommates in the same dormitory have different progress. Some have already read the eighth page or even the tenth page, but others have only understood the first two pages.

So if he starts to lecture, no matter which page he talks about, it will be unfair to others.

He simply didn't say anything.

After a few days, when he returns to Harbin Institute of Technology, he will gather the students from the Department of Computational Mathematics and start the class again.

When the time comes, he will start from the first page, and it will all depend on the individual how much he can understand.

The next day, Wang Duoyu and his friends had a good meal and finally returned to Harbin Institute of Technology.

As soon as he arrived at Harbin Institute of Technology, Wang Duoyu went to talk to Wu Congyin about this matter.

When the latter heard this, he was overjoyed.

"You're finally willing to teach. That's great! I'll arrange it right away!"

At the end of June, Li Rui and Liu Deben, two parents of students from Harbin Institute of Technology, talked to Wang Duoyu and wanted to hire him as an associate professor at Harbin Institute of Technology.

Even though he only graduated with an undergraduate degree, and even graduated in April, two months later, Harbin Institute of Technology actually wanted to hire him as an associate professor, which was a huge promotion for him to the same position as Liu Taoshun.

Tsk!
However, Wang Duoyu refused at that time. After all, he didn't even have a master's degree, let alone a doctorate.

Moreover, before the final exams last year, Liu Deben had already applied for lecturer treatment for Wang Duoyu, but he did not receive these benefits because he had never attended any classes.

What's more, if he received these benefits, he would not be able to receive the national subsidy of 24 yuan per month for college students.

Because of this incident, Wu Congqin and others have been feeling helpless because they are afraid that Wang Duoyu will run away.

Now he proposed to give a lecture on the paper "Poincaré Conjecture in Four-Dimensional Space" to students in the Department of Computational Mathematics. Wu Congyin was of course very happy.

Half an hour later, when Wang Duoyu was still reading aerospace books in the office, Li Rui, Liu Deben, Han Jue and others all came over.

"Comrade Duoyu, Director Wu just told us that you're going to give a lecture. Is this true?"

In the office, apart from Wang Duoyu, only Yang Xiuhua was there; everyone else was out.

Yang Xiuhua was a little surprised when she saw that all the school leaders had come.

She knew that the school attached great importance to Wang Duoyu, but she didn't expect that Secretary Li and others would make such a fuss just because Wang Duoyu said he wanted to start a class. Isn't it a bit too much?
Wang Duoyu also felt that Liu Deben and the others were making a big deal out of nothing. Was it worth all the trouble for such a small matter? It wouldn't be necessary for both parents to go there in person.

"Well, Secretary Li, Principal Liu, of course this is true!"

"Good good!"

Li Rui and Liu Deben were immediately delighted and said yes.

After being happy, Liu Deben immediately said:
"Duoyu, I'll make the arrangements for you right away. From today on, you'll be an associate professor in the Department of Computational Mathematics at Harbin Institute of Technology, enjoying a level 7 salary."

Hearing the other party's words, Wang Duoyu asked in surprise:
"Principal Liu, you know I'm an intern researcher at the Institute of Mathematics of the Chinese Academy of Sciences, and I'm earning a 12th-grade salary. If I were to earn a 7th-grade salary now, that wouldn't be allowed, right?"

"These things are no longer important now, and you are in a different unit, so you don't need to worry about this."

Liu Deben's words made Wang Duoyu decisively choose to remain silent.

In that case, let them arrange it themselves.

Although this may upset many people who know the inside story, as long as he keeps it confidential, then none of this will be a problem.

The fastest professor appointment letter in the history of Harbin Institute of Technology appeared in front of Wang Duoyu at almost the speed of light, and the youngest professor in the history of Harbin Institute of Technology was born on July 9th.

As an associate professor at Harbin Institute of Technology, Wang Duoyu does not have many tasks. He can give lectures every year or not, depending on his own preference, but he must have scientific research projects.

However, considering that Wang Duoyu has just completed the Poincare conjecture in three-dimensional space, Liu Deben and others directly stated that this year's scientific research tasks do not need to be completed for the time being.

If there is a lecture arrangement, Wang Duoyu still needs to apply to Wu Congqin in advance, after all, this needs to be arranged in advance.

It's summer vacation now and the final exam results have just come out.

Many students did not leave school, so many of their classmates already knew the results.

So now Wang Duoyu wants to start a course on the Poincare conjecture in four-dimensional space, which is a pity for some students who have already left school.

Jian Xianglan has already seen her final exam results. She ranks first in the department, which means she has secured a spot to study in the United States.

Zhu Hanting ranked third, and Dai Yian ranked second.

However, Dai Yian was not very happy, because even if he ranked second, he might not be able to get a spot.

Ranked fifth was Rong Guangxia, who had a bitter taste in his mouth, knowing that there was no hope this time.

Even though Rong Guangxia had published a paper, it was useless.

Xue Xiaoling was only ranked ninth, which was even more impossible. She had already given up thinking about studying in the United States because she had already decided to "save the country in a roundabout way" and was determined to take this path.

In the dormitory, Xue Xiaoling just came back and heard the latest announcement from her roommates: Wang Duoyu is about to start a class and will talk about the paper on the Poincare conjecture in four-dimensional space this summer.

The specific start time of the class has been decided, it will be tomorrow morning.

There are two hours of lectures every morning, and the rest of the time is free.

Xue Xiaoling screamed when she heard the news.

When Jian Xianglan heard the news, the smile on her face froze instantly.

Because if she remembered correctly, on July 13, the students studying in the United States would leave Harbin Institute of Technology, gather in BJ, and then go to Hong Kong Island.

Like her, Zhu Hanting also had complicated feelings.

He knew his results and there was no way he could escape with a spot.

In that case, he would not be able to attend Wang Duoyu's classes.

So is it better to study in the United States or stay in Harbin Institute of Technology?

As for complaining about Wang Duoyu not starting the class earlier?
Haha, whether it was Jian Xianglan or Zhu Hanting, neither of them dared to have such thoughts.

Because if Wang Duoyu had not completed the proof of the Poincare conjecture in three-dimensional space, he might not have taught the course.

In Dormitory 303, Rong Guangxia was feeling quite lost. Seeing Zhu Hanting with no smile on his face, he couldn't help but comfort her:
"Old Zhu, you're going to study in the United States. You'll definitely be more impressive than us when you come back. You should learn a lot over there and bring back all the American technology."

Yuan Jigang just laughed:
"Old Zhu, did you see that? Duoyu starts teaching tomorrow, and he's an associate professor now. Hey, we can't be so rude in the future. We can't call him Duoyu anymore. We have to call him Professor Wang!"

Looking at his cocky look, someone who didn't know him would think he was the professor.

Lou Jianguo, Yu Xinyao, Tian Maohua, Mo Ruogao and others also echoed a few words. Upon hearing this, Zhu Hanting shook his head and smiled bitterly.

Although he firmly believed that he would be able to make a name for himself by studying in the United States.

But now, he suddenly lost this confidence. There was always a voice deep in his heart telling him not to go to the United States, but to stay in the country.

However, this voice was soon drowned out by the envious praises of Yu Xinyao and others and disappeared.

The next day, at 9:30 am on July 10, the large lecture hall in the teaching building of the Department of Computational Mathematics was packed with people.

It's only half past nine, and the lecture hall is already full of people. There must be at least three hundred people here, right?
Because it was very crowded, all the students from the previous class and this class were there, as well as students from other departments who came specifically to audit the class.

After all, Wang Duoyu is the youngest professor in the history of Harbin Institute of Technology. Many of the students present are older than Wang Duoyu, but Wang Duoyu's fame is much greater than the combined ages of all of them.

Soon, many people came to the door, and some students thought that the class should not be held in the lecture hall, but somewhere else.

Wu Congqin, who rushed over after hearing the news, was shocked by the scene in front of him as soon as he followed Su Zhenghuai and others into the classroom.

So, ten minutes later, an urgent notice came: the class venue was changed to the auditorium!
