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

Chapter 204, Liu Xiaoli returns to the village, GT316
March 25, 1982, Teaching Building of the Department of Mathematics, Harbin Institute of Technology.

Wang Duoyu talked to Andrew Wiles, William Thurston and Gerd Faltings separately, and in the end it was the former who accepted the position of editor-in-chief of the Harbin Institute of Technology Mathematical Journal.

However, Andrew Wiles also said that he would only serve for two years and definitely not more than three years.

In addition, he also proposed that Wang Duoyu needs to provide at least half a year of scientific research guidance during these two years.

It's a bit like a master taking in an apprentice on his behalf, but there is no nominal master-apprentice relationship.

In response, Wang Duoyu agreed to the other party's conditions.

No matter what, "HIT Mathematical Journal" cannot remain silent. It definitely needs a more capable person to take it forward.

In two years, Harbin Institute of Technology should be able to cultivate a lot of talents.

Anyway, there are quite a few candidates at present, such as Zhu Chengwu, Xue Xiaoling, Dai Yian and others, but to be honest, these people have not grown up yet.

For example, Xue Xiaoling. Wang Duoyu had said before that her peak was actually that article.

Although Xue Xiaoling worked very hard and was successfully promoted to associate professor of the Department of Mathematics at Harbin Institute of Technology, it was useless. The talent was there, but she just couldn't do it.

In addition, Rong Guangxia and others are also candidates for the journal editor-in-chief. It depends on whether they can go further.

If they can, then they don't have to be the editor-in-chief. If not, then they may have to compete for the position.

After resolving the issue of the editor-in-chief of the "HIT Mathematical Journal", Wang Duoyu also successfully reviewed the twelve papers.

To be honest, he was also very surprised, because among these twelve papers, ten were able to pass the final review smoothly.

Six of them were written by Yang Nianzhen and his other six disciples, which means that his six disciples actually completed their papers.

It’s pretty good. The six papers in the sixth issue are mainly those by Yorks, Yang Nianzhen, and Bochers, while the seventh issue contains the other four papers.

In addition, he will publish another special issue to publish the paper on the honeycomb conjecture.

After Wang Duoyu informed his current editor-in-chief Wiles of his intentions, the latter began to take action.

As the editor-in-chief, Wiles must of course do his job well, otherwise Wang Duoyu will not guide him.

Wiles has also read all the papers in the sixth issue. He was very surprised and very glad that he accepted Wang Duoyu's invitation.

Otherwise, he might continue to waste his time.

“His coaching ability is really strong.”

Andrew Wiles muttered to himself, and then asked Yang Xiuhua and others to hurry up to typeset and print the paper and publish it quickly.

While we were busy here, the house numbers outside the Harbin Institute of Technology, actually the several Polar Bear Empire-style buildings next door, had been changed.

The big words "Ice City Advanced Research Institute" have been arranged, and it will be officially established after a while. At this time, Wang Duoyu, as the dean of the School of Mathematics, is just a commander without troops.

Before Wang Duoyu could talk to William Thurston and others again and recommend them to the School of Mathematics of the Ice City Institute for Advanced Study, John Milnor, Shing-Tung Yau, Robert Langlands and others had already arrived safely at Yanjiagang Airport in Ice City.

When the news of over twenty of the world's top mathematicians arriving in Bingcheng reached the office of Bingcheng's top leader, Tong Jianwei's pupils widened in shock. "Could it be that Wang Duoyu has done something big again?"

It's easy to guess why these mathematicians came to Ice City.

The second-in-command Kang Yumin went to the airport to greet him in person, and then he also saw Chen Shiing-Shen, which surprised the former.

Although Chen Shiing-Shen was at Nankai University in Tianjin and he often came to Harbin Institute of Technology, this time was different.

With the arrival of people like Shiing-Shen Chern and Robert Langlands at HIT, the campus became even more lively.

At this point in late March, Harbin Institute of Technology was already very busy because the graduate school admissions process had already begun and this year's college entrance examination was approaching, so the application process was also very important.

Although the Ice City Institute for Advanced Studies is independent of Harbin Institute of Technology, it actually relies more on Harbin Institute of Technology now, and the two will definitely have a mutually influential relationship in the future. Independence is certain, but complete independence is absolutely impossible.

In short, there is a lot of work to do, so Harbin Institute of Technology is naturally very busy.

Because it is busy, it is also very lively.

"You said there are more than 20 mathematics professors coming from the United States?"

When Wang Duoyu received Han Jue's call, he was also quite surprised, and then said:
"Since they're here, let's treat them to some good food and wine. I'll chat with them after they adjust to the time difference."

After hanging up the phone, Wang Duoyu's mouth curled up slightly. He had originally thought of using the sixth issue of "HIT Mathematical Journal" to attract a wave of talents to HIT.

He didn't expect that so many talented people would come before he even started. Hehe, it was just right to use the geometric Langlands conjecture to retain some talents.

Especially Robert Langlands, he is definitely willing to take the lead in solving the geometric Langlands conjecture.

That evening, Wang Duoyu attended the welcome banquet, but did not drink any alcohol. He just exchanged pleasantries and had a brief conversation.

The next morning, the latest announcement was posted on the bulletin board of the Department of Mathematics teaching building. An exchange meeting of top mathematicians would be held in the auditorium, and students who wanted to attend the class could register in advance.

At once, many people signed up.

There aren't that many people in the mathematics department, but there are definitely quite a few.

Many of the people who registered were actually students and teachers from other departments.

And the foreigners in the visiting scholar exchange group will definitely go and participate.

The registration time was in the morning and the exchange meeting started at two o'clock in the afternoon. As a result, many people came to the door of the auditorium at half past one.

At 1:50, when Wang Duoyu appeared in the auditorium, it was already full of people.

To be honest, Wang Duoyu was also quite surprised. This was a communication between mathematicians and a confrontation between geniuses. Could ordinary people really understand it?

Why do these people like to join in the fun so much?

If Liu Deben, Wu Congyin and others had not insisted on holding the event in the auditorium, Wang Duoyu would even have preferred to have a casual chat in the conference room.

Of course, since it is being held in the auditorium, everything has to be more formal.

Since it is an exchange meeting, it is very different from other forms such as lectures.

In the front row sat André Weil, John Milnor, Charles Fefman, Lars Valerian, and Robert Langlands.

The first person to come on stage and ask questions was Smale, who was more concerned about whether Wang Duoyu had proved the honeycomb conjecture.

Wang Duoyu heard this. He had already planned to submit this paper for review. Now that Smel had asked the question, he smiled and replied:

"Yes, I have already proved it. The paper will soon be submitted to Andrew and others for preliminary review. It would be my honor if you could help review it."

"I knew it, I knew it"

Smale instantly became excited, and his expression became extremely exaggerated. I really didn't know if he was acting or was born that way.

"You've indeed proved the honeycomb conjecture. God, I don't know how to describe how excited I am! Where's your paper? I really want to read it. Oh my god, I'm so honored."

There was a brief commotion in the auditorium just as the exchange meeting began.

However, after Smel calmed down, the exchange meeting began to get down to business.

The geometric Langlands conjecture is one of the key topics of discussion at this conference. Both Shing-Tung Yau and Charles Feefman will not limit themselves to this conjecture.

As time went by, the exchange was intense but not interrupted by the outside world.

Wu Congqin was worried about Wang Duoyu's health, so when the latter didn't speak, he couldn't help but remind him to get more rest.

"Director, I know, you don't have to worry."

The entire exchange meeting lasted nearly three and a half hours and was divided into two sessions.

Everyone gained a lot.

After the exchange meeting ended, Wang Duoyu was still pestered, and everyone wanted to see his paper.

Taking this opportunity, Wang Duoyu said:

"In that case, I will have the paper delivered to you shortly. I hope you can help review it. During your stay at Harbin Institute of Technology, we will arrange food and accommodation for you. You don't need to worry about these issues."

Upon hearing this, Smel and others did not worry about food and accommodation. They were more concerned about the thesis itself.

Because it was not their first time to come to Harbin Institute of Technology, whether it was Wang Duoyu or Liu Deben, everyone from top to bottom was very hospitable, so everyone was very relieved about these external matters.

Even in the Ice City at the end of March, the temperature is still very cold, but the heating in the Ice City has not been turned off.

Harbin Institute of Technology also has warm corridors, so people don’t have to worry about being exposed to the northwest wind when going to different teaching buildings, cafeterias and other places.

That evening, Smel and his colleagues received the manuscript of the paper sent by Wang Duoyu.

So the paper review began.

In the next few days, Shing-Tung Yau, Smale, Charles Feefman and others were reviewing the papers, while Chern Shiing-Shen, André Weil and other old guys found Wang Duoyu for private communication.

In less than three days, even though April had not yet arrived, the sixth issue of "HIT Mathematical Journal" was successfully published, and Chen Shiing-Shen and others had seen it.

At first, they didn't take it seriously, until they opened the table of contents and saw the authors of the paper, then they all lost their composure.

What the hell?

All six papers are written by Wang Duoyu’s students?
Is it cheating?

Or is there any special situation?
Half a day later, everyone had taken a quick look at the six papers. The quality was indeed very high, but no one quite believed it. Were these really the papers completed independently by Yang Nianzhen and his colleagues?

How much did Wang Duoyu contribute to this?
However, no matter how much Wang Duoyu contributed, the strength of the six people including Yang Nianzhen is definitely not low.

So, is Wang Duoyu's teaching ability really that strong? Or are Yang Nianzhen and the others' talents actually not much worse than Wang Duoyu's?

With these questions, Chen Shiing-Shen and his team found Wang Duoyu again.

"Professor Wang, tell me the truth, how much of these six papers did you participate in?"

"Professor Chen, everyone, don't you already have the answer in your hearts? Why are you still asking me?"

Wang Duoyu laughed and said:
"You've all been at Harbin Institute of Technology these past few days, and you've often come here before. Plus, we've been in contact for so many years. Don't you know what kind of person I am?"

"They did write the paper themselves, there's no need to question it. If you don't believe it, then I can't help you."

"I'm very busy on weekdays and don't have time to deal with these trivial matters, so do you have any questions?"

What could be the problem?

Chen Shengshen and the others all had complicated expressions. It could be seen that Wang Duoyu's teaching talent was not much worse than his own mathematical talent.

No matter what they think, Wang Duoyu is now doing his work step by step.

There is no rush regarding the Ice City Institute of Advanced Studies. Even if it has been established, let's just ignore it for now.

Instead, a research team for the geometric Langlands conjecture should be established.

We can discuss what to do specifically after John Milnor and others review his paper.

The next day, April 1st arrived as scheduled. After getting up, Wang Duoyu prepared to go to work. He planned to return to his hometown on the 3rd, so he continued to work for the next two days.

Even for Shing-Tung Yau and others, it took more than half a month to review the paper on the Honeycomb Hypothesis. If it was a more detailed review, even the kind that nitpicked, it would take even longer.

Therefore, it would be possible for Wang Duoyu to receive the results of their review of this paper only after he returns from the Qingming Festival holiday.

"Brother Jiu, Qingming Festival is coming soon. When are we going back?"

While having breakfast, Wang Meili suddenly asked.

Actually, she asked this question on behalf of Liu Xiaoli.

More than half a month has passed, and Liu Xiaoli still hasn't found an opportunity. She is getting anxious.

After all, little guy Wang Junhong is willing to call Liu Xiaoli "Mom", so it's time to move on to the next step.

"You'll be leaving on the 3rd. Just pack up for the next two days and see if there's anything you need to take back. We'll arrange transportation in advance."

Wang Duoyu said lightly:

"Also, your studies have been slowing down these days. You need to pay attention. It's already April, and a quarter of the year has already passed. If you still want to make money, you need to be more careful."

"If you don't want to make money, then tell me earlier and save me the trouble of wasting my time."

The two sisters quickly said that they would work hard.

They were just enthusiastic for three minutes, and Wang Duoyu was not surprised because it was like this every time.

He is good at shouting slogans but slow in doing things.

After dinner, Liu Xiaoli showed up, very punctual every day.

Just as he was about to get in the car, he suddenly stopped, then looked at Liu Xiaoli and asked, "Xiaoli, don't you have to go to work? You come here every day, and I don't pay you. You don't have to do this."

"I'm happy, can you take care of it?"

When this was mentioned, Liu Xiaoli got angry and couldn't help rolling her eyes and retorting.

"Yes, I can't control it. Do whatever you want."

Wang Duoyu, who had been frustrated, said unhappily.

He was too lazy to argue with the other party and now just wanted to concentrate on his career and not be distracted by other things.

On the other hand, he and Zhu Ling have only been divorced for more than three months. It is indeed not a good idea for him to be so anxious to find the next one.

Otherwise, Liu Xiaoli would have been eaten up by him long ago.

In the next two days, Wang Duoyu was busy with work, but the mathematics departments of universities in Beijing, Shanghai, Guangzhou, Nanjing and other places were all shocked after receiving the sixth issue of "HIT Mathematical Journal".

The value of this journal is still increasing, but no one expected that the sixth issue would be like this.

Wang Duoyu's six students had already been reported very clearly by those newspapers.

So how could we not be surprised that the papers of these six people all appeared in the sixth issue?
My friend was really shocked!
This is the case here in China, and it has caused an even greater sensation abroad.

It seems that the three words "Wang Duoyu" are very magical, attracting everyone to the Ice City of China.

Wang Duoyu had no idea what the outside world’s reaction was. He had already returned to his hometown with his son and two sisters.

Zheng Baoyin and others also came back. They were all called back by Wang Duoyu.

You have to make money, but you also have to take care of your family.

Hometown is everyone's root. Even Wang Duoyu has come back. It would be unreasonable if they didn't come back.

However, when Zheng Baoyin and his team returned to Dahonggou Village, the entire village and the nearby villages were all in a sensation.

On the 4th, the day before Qingming Festival, at the end of Dahonggou Village, near Wang Duoyu's wooden house, men, women, young and old from several villages all came here.

Everyone is not here to watch the fun, but to hope that Wang Duoyu and others can help them make a fortune.

Two months ago, during the first few days of the Lunar New Year, Zheng Baoyin and his family hurried back. Almost every household in Old Wang's family had suddenly become modernized, with televisions, refrigerators, washing machines, radios, and so on, all fully equipped.

With so many home appliances appearing all of a sudden, the village's old electrical wires are no longer enough.

It was Wang Duoyu who paid for it and asked someone to help replace it.

Of course, just replacing the wires is not enough, transformers and other things must also be arranged.

This is not a small amount of money.

However, in order for Dahonggou Village to fully enter the modern era and experience these home appliances, it is necessary to update the power transmission equipment.

When Kong Huayi, the team leader of the Qingshan Township production team, learned about this, he couldn't help but sigh: When one person's success comes, the whole family will benefit. The Wang family really deserves to be rich.

At this time, at Wang Duoyu's house, the big TV in the living room was playing a very old TV series. Anyway, it was difficult to receive several TV stations unless you used a satellite dish.

VCD players and the like had not yet appeared, so ordinary families could not afford to buy black and white film and film projectors to play movies.

It was at this point in time that Hong Kong and Taiwan films entered the mainland, but everyone went to video halls to watch TV series such as "The Bund", "Drunken Master", and "Chu Liuxiang". Most of them were in Guangzhou and other southern areas. It was relatively rare to see them in the mainland.

Little guy Wang Junhong was very happy playing among his brothers and sisters, nephews and nieces and other younger children.

On the other side of the living room, Wang Duoyu was sitting aside. His eldest brother, third brother, eighth sister and others were all there, holding a "family meeting".

There were so many elders and fellow villagers outside the house, and they were all related to the Wang family, so Wang Duoyu didn't care about their requests, but his elder brother Wang Shoucheng had to care.

Lao Wang’s family has its roots in Dahonggou Village, so this matter needs to be handled with caution.

But everyone also has to fully consider Wang Duoyu's opinion, otherwise, if he gives up, it will be a big joke.

"Brother, I only have one request. They can come to Bingcheng, but whether they can enter the garment factory or the watch factory depends on their ability. If they pass the interview, then we will accept them. If they fail, then they will go back to where they came from."

Wang Duoyu raised a finger and said:
"I didn't grow up eating at other people's houses. Those relatives have nothing to do with me!"

"In fact, such a small matter should not reach my ears, because I am here to help everyone get rich. If Want Want Group collapses, then I have nothing to say. I will just start a new business. But your words..."

"So, Big Brother, Third Brother, you can consider the overall situation, but you must clearly distinguish whether this overall situation is the happiness of your own children and grandchildren, or the overall situation of your own reputation."

"Mr. Zheng, Mr. Wang, you are the senior management of Want Want Group. You are the ones who know the company's rules and regulations best. If anything happens to the company because of these relatives, I will first remove your positions and then kick you out of the Want Want Group's shareholders' meeting. Do you understand?"

Upon hearing this, Zheng Baoyin and Wang Jianchao's expressions suddenly changed and they became torn.

Especially Wang Jianchao, his father is Wang Duoyu's third brother Wang Duozhi. On one side, there is pressure from his father, and on the other side, there is pressure from Wang Duoyu.

It's very difficult.

But as it stands now, no matter how difficult the decision is, he has to make it.

The family meeting was over, and Wang Duoyu finally had some peace and quiet.

The next day was Qingming Festival, and the family went to worship their parents and ancestors. Many kids didn’t understand much and just followed what the adults did.

But even if I was confused, I already understood that inheritance is so subtle.

After the ancestor worship ceremony, Wang Duoyu stayed in his hometown for three days. He went into the mountains and fired a few shots to relax.

But it wasn't very satisfying, because hunting requires patience and luck.

It was only three days, and to be honest, I didn't even explore the mountains much, so naturally I didn't gain much.

Wang Duoyu got used to going out hunting, which would last at least half a month each time.

Three days later, on the morning of the 9th, he returned to Harbin Institute of Technology with his two younger sisters, Liu Xiaoli and his son.

Yes, Liu Xiaoli still came to Dahonggou Village as a friend.

It’s just that she only arrived in the afternoon of the 5th, and did not come back with Wang Duoyu and the others.

These days, she has been living with Wang Meili and her two sisters because she has no other choice.

She wanted to live in the wooden house, but Wang Duoyu didn't give her the chance, so she could only take it slowly.

After returning to Harbin Institute of Technology, Wang Duoyu did not meet Qiu Chengtong and others, but met Xi Guangan and others instead.

"Professor Wang, this is a solid-state drive made in our laboratory. We have tested it and it perfectly meets the requirements you mentioned earlier."

As the mainstream of the future memory market, solid-state drives use logic gate circuit flash memory technology as storage media, which is completely different from the rotating disk of traditional mechanical hard drives.

IBM's 3340, 3380, and Seagate's ST506 and other products are all mechanical hard drives that use IBM's innovative "flying head" technology invented in 1961.

In the current 1980s, mechanical hard drives are the absolute protagonists, and there is still extremely broad room for development.

Because many companies such as IBM are updating and iterating their technology in this direction, while flash memory technology only appears in Toshiba, and Toshiba only uses flash memory technology as a weapon to attack its competitors.

Therefore, the new storage technology, flash memory technology, has not yet been well developed.

The advantages of mechanical hard drives are large storage capacity, relatively low manufacturing cost, long data retention time, and many read and write times, but their disadvantages are slow speed, poor shock resistance, high energy consumption, and high noise.

One of the most important features of solid-state drives based on logic gate circuit flash memory technology is the ability to retain data after power failure.

Flash memory is made up of millions of storage cells, each of which can store different bits of data and quickly switch data states through electrical signals to complete read and write operations.

Under the guidance of Wang Duoyu, the solid-state hard drive developed by Xi Guangan and his team as the main scientific research team is also equipped with a main control, which is an embedded processor.

This processor is responsible for managing data and performing retrieval tasks. It also includes error correction, write balancing, bad block management, data storage optimization and data encryption, ensuring the efficient and stable operation of the solid-state drive.

Therefore, solid-state drives, with their high performance and non-volatility, have gradually become dominant in scenarios such as databases, backups, and secondary disks.

However, the solid-state drive that Xi Guangan and his team have now produced is 2.5 inches in size and 20MB in capacity. It is relatively large in size but has a relatively small storage capacity.

After all, the storage capacity of Huashun's HS213 hard drive has reached 125MB.

After listening to Xi Guangan's introduction, Wang Duoyu pondered and said:
"You still need to optimize your technology. We can start from the principle of program locality, which is the foundation of high-speed storage power. We can use program analysis and optimization to improve the locality of the program, thereby improving the performance of high-speed storage. This does not require proprietary hardware support and has good cross-platform features."

"Here I'd like to offer several improvement ideas. First, we'll analyze key factors that determine high-speed storage performance, such as failure rate, failure overhead, and hit time, for design and optimization of high-speed storage for multi-threaded applications."

"In the 1960s, some people proposed adding an additional parallel path during data transmission to improve reliability through redundancy. This redundancy in data transmission requires very few resources, but the improvement in reliability is limited. In extreme cases, error correction is not an option, and it is even impossible to determine whether an error has occurred."

"Therefore, compared to data transmission, data redundancy in memory requires long-term stable preservation, which often requires high hardware costs. So, my second suggestion is to build on the traditional triple-module redundancy with an optimally divided triple-module redundancy mechanism. This will effectively reduce additional hardware costs while ensuring data reliability."

"The third is data encryption. I've already told you about the concept of multimedia information hiding technology, including a complete set of solutions from mathematical models to specific implementations, such as information hiding technology based on chaos generators."

"The fourth is multi-level cell flash memory technology. This uses a large number of voltage levels, allowing each cell to store two bits of data. This results in a relatively high data density. However, this technology is relatively difficult. If you encounter any difficulties during the research and development process, please feel free to contact me."

Xi Guangan and the others hurriedly took notes and recorded these key points.

Half an hour later, after Wang Duoyu finished chatting with them, he carefully asked questions about the production process.

Solid-state drives have been developed, and the first product is the one Wang Duoyu currently has on hand.

The specific model follows the tradition of Huashun Company, GT316, this is the name and there is no need to change it.

The mechanical hard drive series starts with HS, the solid-state drive series starts with GT, and the optical disk series starts with GP.

"Professor Wang, we can always spare time to guide the factory in debugging the production line. This is not a big problem."

Xi Guangan hesitated and said:

"But the problem now is insufficient funds, and the technical research and development directions you just mentioned are too complicated to be honest. We need more manpower."

Upon hearing this, Wang Duoyu immediately agreed to the other party's request.

If you want a horse to run fast, you must feed it grass, and feed it enough so that the horse is full.

If the horse gives up halfway, it is definitely not what Wang Duoyu wants to see.

Therefore, even if Liu Deben and others disagree, Wang Duoyu will definitely support Xi Guangan and others to the end.

"Thank you, Professor Wang, thank you." Xi Guang'an bowed in delight, but Wang Duoyu frowned. "Team Leader Xi, you've already made some achievements, and I've long told you that you don't need to worry about funding or talent. Why are you like this now? Did someone tell you something?"

In Wang Duoyu's opinion, something must have happened, otherwise Xi Guangan would not be so excited.

You should know that in the entire Harbin Institute of Technology, basically everything Wang Duoyu said was fulfilled.

In addition, he has a very high status in Harbin Institute of Technology, which is something everyone knows. As Wang Duoyu's subordinate and the head of the project department, Xi Guangan cannot be unaware of this matter.

However, even if he knew it, Xi Guangan seemed to be worried that Wang Duoyu would not provide him with funds and talents.

This made Wang Duoyu puzzled.

"No, no, Professor Wang, you're overthinking it. We've already finished our report, so let's get back to work."

The smile on Xi Guangan's face suddenly froze, and then he quickly ran away.

In fact, there were two main reasons why he was so anxious to clarify the issue of funding and talent with Wang Duoyu.

First, the capital investment in solid-state drives is indeed huge, especially the points mentioned by Wang Duoyu just now. Even with an investment of 30 to 40 million RMB, it may not be successfully developed.

With such a large amount of funds, even with Wang Duoyu's efforts, the leadership of Harbin Institute of Technology may not be willing to provide it, or may not be able to come up with the money.

why?
Harbin Institute of Technology is obviously very rich!
But Xi Guangan is not a scientific research fanatic who only focuses on the project and has no idea what is happening in the outside world.

Indeed, in the first two months of this year, Huashun Company earned a revenue of 1.6 billion US dollars thanks to its handheld game console product.

With such crazy income, how could Harbin Institute of Technology be short of money?
But Xi Guangan also heard some rumors that Harbin Institute of Technology has successively established dozens of large projects in mainland China, all of which are scientific research projects related to aerospace.

Although it has only been established as a project and only has a project code, we don’t even know what the specific project is.

In other words, the rumors Xi Guangan and others heard were about aerospace scientific research projects, which were probably just speculation.

However, Xi Guangan himself knew that it was not a guess, but a true fact.

After all, Harbin Institute of Technology has a limited team of scientific research talents, and many professors, teachers, doctors, etc. who are familiar with Xi Guangan were called in for talks one by one.

Perhaps in the next six months, Harbin Institute of Technology will really have a big project to be implemented.

On the other hand, Harbin Institute of Technology is still recruiting a large number of college students, masters and doctors, as well as special talents and geniuses who can pass the interview of Harbin Institute of Technology. They can all join Harbin Institute of Technology.

According to what Xi Guangan learned from the recruiting teachers, these recruited talents come from all walks of life, such as materials science, welding, mechanical design, etc.

Therefore, various signs have indicated that this is going to be a project related to aerospace.

Can this kind of project be a small project?
It is definitely a super large project worth hundreds of millions or even billions of dollars.

Since there is such a super large project, a large part of Harbin Institute of Technology’s funds will definitely be withdrawn.

Even if Huashun Company brought in 1.6 billion US dollars in revenue at the beginning of this year, it still could not withstand the capital investment in the super large project.

It would be better if such large projects had more sufficient funds, as there would certainly not be as much funding for other small projects.

Xi Guangan is a smart man. Even if he guessed this, he would not say it.

Even many professors and experts at Harbin Institute of Technology have sewn their mouths shut and will not say a word to anyone.

Even if they guessed it, they would just keep it in their minds and not discuss it with others. Even to their wives, they would not say a word.

The second point is the current research and development status of solid-state drives, which is likely to require a large number of talents.

There is currently a severe shortage of talent in China. Harbin Institute of Technology itself is short of people. Even if the salary is increased a lot, it cannot attract those big names in the field.

However, memory is the most cutting-edge technology field in the entire computer industry, especially solid-state drives, which are completely ahead of the international level.

In this case, the first thing Xi Guangan and his team need to consider when recruiting talents is loyalty.

Therefore, this project only requires our own people and no foreigners can be used.

With such restrictions and the need for people with strong technical skills, it is really hard to say whether we can recruit the people we need.

Based on the above two reasons, Xi Guangan is so worried.

Watching Xi Guangan and the others leave, Wang Duoyu frowned and thought for a while, then put the matter behind him.

The next day, on April 10th, Smale, Shing-Tung Yau, John Milnor, William Thurston and others came to see Wang Duoyu.

As if they had made an appointment, they blocked Wang Duoyu at his doorstep when he was about to go out to work in the office of the Mathematics Department's teaching building.

Liu Xiaoli had just arrived and was holding the little guy Wang Junhong, but she didn't expect to see this scene.

"You are here, come in and sit down."

Wang Duoyu saw that there were sixteen people in their group, which was not a lot, but not a few either.

With just a quick glance, Wang Duoyu knew that these people must have read his paper proving the honeycomb conjecture, so they came to see him together.

Shing-Tung Yau and his friends did not exchange pleasantries. After entering, they exchanged a few simple pleasantries with Wang Duoyu, and then could not wait to ask about the details of the paper proving the honeycomb conjecture.

"Wait a moment, I'll get out the mobile blackboard." Wang Duoyu said immediately after hearing this.

A mobile blackboard is one of the essential tools in the home. In fact, under normal circumstances, it is only placed in the study.

But if everyone is in the study, the room will seem very crowded, so it would be much better to move out to the living room.

So, they used the living room as an office and started talking.

Liu Xiaoli, Wang Meihe, and Wang Meili were all dumbfounded. After listening for a while, they quickly left.

Because I totally couldn't understand what Wang Duoyu and the others were talking about.

And the mathematical symbols on the moving blackboard are like the ghostly scribbles of a Maoshan Taoist priest, which are completely incomprehensible.

Since you can't understand, why don't you run away quickly?
Am I going to stay and pretend to know everything?

In the 1940s, Hungarian mathematician Taus had proved that among all regular polygons connected end to end, the regular hexagon has the smallest perimeter.

Now, Wang Duoyu has combined the knowledge of real variable functions and differential geometry to provide a complete proof that does not require the convexity assumption, thus completely solving the honeycomb conjecture in the plane case.

The mathematical principles of the honeycomb conjecture involve the application of plane geometry and solid geometry. Wang Duoyu used calculus and geometry to prove that the hexagon is the optimal choice. This is not only of great significance in mathematics, but also widely used in engineering and architecture.

In the next two hours, Wang Duoyu, Qiu Chengtong and other 16 top mathematicians gave a paper report.

In fact, everyone has understood Wang Duoyu's proof paper and can also understand the mathematical tools proposed by Wang Duoyu.

But they also have a lot of problems, so they need to solve and discuss them face to face.

Such opportunities are actually very rare.

Because there are not only top mathematicians who have won the Fields Medal such as Smale, John Milnor, and Charles Feefman, but also top mathematicians of the younger generation such as William Thurston and Shing-Tung Yau who are very likely to win the next Fields Medal.

So it is a rare opportunity for this group of people to get together.

After two and a half hours, everyone had no more questions, but this "communication and discussion" was not over.
