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

Chapter 166, Presentation at Princeton University

"Principal, if foreigners also imitate our Diao brand batteries and then produce and sell them on their own, should we just ignore it?"

Wang Duoyu's rhetorical question completely confused Liu Deben.

By now he must have realized what was happening and would never say anything so shameless as he did just now.

After a while, Liu Deben trembled and said:

"Those ten lithography machines are too many. That's $4.5 million."

How can you accomplish anything if you are so stingy?
To be honest, Liu Deben is a very generous leader, but unfortunately he met Wang Duoyu, who spends money lavishly.

The latter wants more, which is to take the lead in technology and strike a dimensionality reduction blow to the prosperous gaming industry. He wants to get a piece of the pie, or even the biggest piece of the profit pie.

Therefore, if you want to reap, you must first sow.

Seeing that Liu Deben disagreed, Wang Duoyu shook his head and said:
"In that case, let's purchase one. I'll need to trouble the Secretary and the President to negotiate with the 45th Institute of the Ministry of Mechanical and Electrical Engineering and the 109th Factory of the Chinese Academy of Sciences. I need their help in developing a more advanced lithography machine. However, the research funding will be much higher, probably no less than million RMB."

Liu Deben’s eyes went dark and he almost fainted.

After a while, he finally reacted and raised three fingers to Wang Duoyu:

"30 million RMB?"

Wow, spending 4.5 million US dollars to buy ten lithography machines is only about 6.7 million RMB.

But after this proposal was rejected, Wang Duoyu actually came up with the idea of ​​developing a photolithography machine, and asked the 45th Institute of the Ministry of Machinery and Electronics and the 109th Factory of the Chinese Academy of Sciences to jointly develop a more advanced photolithography machine, and the total research and development funds should be no less than 30 million yuan?

Suddenly, Liu Deben's brain began to tremble violently.

In fact, he was mentally prepared, but he never expected that Wang Duoyu would have so many tricks up his sleeve.

It's simply impossible to guard against.

"Yes, that's settled then."

Wang Duoyu nodded, then looked at Xue Yuheng and the others and said:
"Teacher Xue, you've heard it all. Next up, you'll be responsible for chip design and development projects. We'll need your help liaising with the 45th Institute of the Ministry of Mechanical and Electrical Engineering and the 109th Factory of the Chinese Academy of Sciences."

Xue Yuheng and the others were already dazed at this moment, but Li Kangmin reacted quickly and asked:

"Professor Wang, we don't know how to develop a lithography machine. It's too difficult."

Although Wang Duoyu did not say what kind of lithography machine it was, it was definitely not an ordinary lithography machine.

The United States launched its first contact lithography machine in 1961 and a stepper lithography machine two years ago. In this field, the United States is the world leader.

It was not until 1977 that we imitated the contact lithography machine, but Wang Duoyu looked down on it and didn't even mention it.

Perhaps the 45th Institute of the Ministry of Machinery and Electronics and the 109th Factory of the Chinese Academy of Sciences are already developing new lithography machines, but it will definitely take a long time, right?

Who knows?

Anyway, no matter what, Wang Duoyu has very high requirements for lithography machines. Perhaps the chips he needs are also very high?

"The second small project is the battery for the handheld game console. Dai Tonghua, Ding Rongqiang, and Peng Xiaoxi will be responsible for this. Who will be in charge will depend on your abilities at the time."

Hearing Wang Duoyu's words, Peng Xiaoxi and others nodded seriously.

In the design of handheld game consoles, the product's power supply is mainly divided into two types: battery and external power supply.

Given the gameplay and portability of this game console, players will definitely consider using batteries when purchasing it.

As a result, the requirements for batteries will be very high.

In Wang Duoyu's design, the handheld game console will have very low energy consumption, but the battery technology must not be too poor.

Therefore, the team that designs and develops this battery will have very high requirements.

With four batteries, the battery life can reach more than 35 hours, and the laboratory standard must be more than 40 hours.

"When the time comes, you can contact Mr. Xin Zhouping, the battery project manager at Diao Pai Company, and discuss more."

After Wang Duoyu finished talking about the second small project, he immediately talked about the third small project.

This project is about the design and development of liquid crystal displays.

LCD screens are not a major at Harbin Institute of Technology, so he had to bring it up.

What a handheld game console needs is a 4-inch LCD screen that can display 2.45 levels of grayscale. This technology is also at an extremely advanced level at present.

Therefore, it must be arranged, otherwise, it will be very disappointing when the time comes.

Although the above three small projects are all hardware-related and the investment proportion is not low, for now, they are still within Liu Deben's acceptable range.

Next are two small software projects, or game cartridge projects independent of the handheld game console project.

In this era, it is impossible to sell game software directly, you can only sell game cartridges.

"Chinese Cube" is such a classic and fun game that it must be released first to let the whole world experience it, and then provide sufficient cash support for the entire handheld game console project.

Otherwise, what will happen if Li Rui and Liu Deben can't bear it due to high blood pressure?
The handheld game console project is destined to be a very expensive project.

Therefore, we must find a way to make money.

This project of Diao Pai Electric Bicycle Company has become profitable and even made a lot of money.

But the leaders above have already fulfilled their promises and given the support that should have been given to Harbin Institute of Technology. Whether it is the Foreign Exchange Department or the Seventh Ministry of Machine Building, they are definitely unlikely to invest a large amount of money in a project that is unlikely to make a profit in the short term.

They dare not take the risk.

You know, when we held the meeting in 1977 and 1978, we had already agreed that when we carried out reform and opening up, we would definitely invest in the petrochemical sector first, because this is our core business and the area we are most familiar with.

But we are not familiar with the gaming electronics industry.

Not to mention that our country is already ahead of South Korea, Japan, Taiwan and other regions in the electronics and semiconductor industries, but we must admit that in the gaming industry, we are really starting from scratch.

Wang Duoyu is willing to take the risk, but even if Li Rui, Liu Deben and others are willing, Fang Li and other leaders may not be happy about it.

Therefore, the game cartridge project comes first.

"How much is the investment in this 'China Cube' game cartridge project? Five hundred thousand?"

Seeing Wang Duoyu stretch out a palm, Liu Deben asked curiously, but the former shook his head and said that an investment of five million was needed.

Why do you need so much money?
Because a large number of computers are needed, a large number of related equipment need to be purchased.

When Principal Liu heard this, his eyes went dark and his face changed drastically.

He was the unhappiest person in today's meeting because Wang Duoyu proposed several small projects one after another, and each project was a money-making beast.

In other words, he was mentally prepared and was very tolerant towards Wang Duoyu.

Otherwise, if someone else proposed these projects and asked for millions or tens of millions of dollars in research funding, Liu Deben would have slapped them in the face long ago.

"Principal, I know you have a lot of confusion, but you can see now that our handheld game console project is not that easy to develop, so we must find other ways."

"China Cube is sure to be a popular and well-received game in the market. It's the only game like this that's the perfect companion for handheld game consoles."

"We can't achieve success overnight. We should be like Diao Pai Company, first completing the research and development of motors, and then gradually tackle smaller projects such as battery technology and electronic control systems."

Hearing Wang Duoyu say this, Liu Deben thought for a moment and said:
"So you're confident in the game 'China Cube'? Are the game cartridges sure to sell well?"

Wang Duoyu smiled confidently, "Principal, can you remove the word 'ma'?"

Everyone in the conference room burst into laughter.

But after laughing, there was a pressure as big as a mountain.

Everyone could tell from Wang Duoyu's tone that the handheld game console project would not be that simple.

Judging from all these preparations, this may be a protracted battle.

"By the way, Principal, we also need to set up a company for this handheld game console project to facilitate future management. As for the name, I have a suggestion: Huashun Company!"

Liu Deben did not refuse, and the others approved the proposal in seconds.

The meeting ended here, and subsequent scientific research funding, follow-up of small projects, etc. will be gradually launched.

Huashun Company has not yet been established, but the company's first project has already started.

After the meeting, Wang Duoyu was called to the principal's office by Liu Deben, who wanted to consult about the scientific research funding issues mentioned in the meeting room.

Is this really necessary? Do I need to pay it all at once?
Wang Duoyu said that it would not be paid in one lump sum, but the funds would only be more or less, and might still not be enough.

Hearing this, Liu Deben nodded with a heavy expression.

"Okay, I understand. I'll discuss it with Secretary Li and give you a reply then."

The next day, Wang Duoyu took out ten test papers and handed them to the relevant person in charge.

These test papers will be given to Peking University, Tsinghua University, Fudan University, Nanjing University and other schools as the test questions for their mathematics departments' final exams this semester.

As long as they can successfully get a score of 80 or above, they can come to Harbin Institute of Technology to attend classes. After Wang Duoyu returns from the United States, he will start this course project.

In July, Wang Duoyu took some time to return to Dahonggou Village. He had no purpose, he just wanted to go back and take a look, that's all.

On July 5th, Wang Duoyu returned from his hometown.
"Are you all ready?"

In front of the teaching building of the Department of Computational Mathematics, Wang Duoyu looked at Lu Jiaxi, Xue Xiaoling, Rong Guangxia, Mo Ruogao, Dai Yian and others. Seeing that they all smiled and indicated that they were ready, he asked everyone to get in the car and set off.

Wang Duoyu definitely did not go to the United States alone to give a report this time.

Harbin Institute of Technology selected ten people from among many students, including Zhu Chengwu and others, to participate in this exchange group.

Among the teaching staff, Wu Congxin, Liu Taoshun and Lu Jiaxi were all there. Including Wang Duoyu, there were a total of twenty people.

Li Rui and Liu Deben, the two patriarchs, did not go with them.

In other words, the highest-ranking official in the Harbin Institute of Technology delegation this time is Wu Congxin.

It was originally a mathematics exchange, so it must be the teachers from the Department of Computational Mathematics such as Wu Congxin who went, not Li Rui and others.

You know, the travel expenses for this exchange still cost a lot of money. Except for Wang Duoyu's expenses paid by Princeton University, there is no way for others to be reimbursed.

All the money is paid by Harbin Institute of Technology.

The group took a car to Yanjiagang Airport in Bingcheng, and then took a plane to Beijing.

After arriving in Beijing, we will rest for one night and fly to Tokyo the next day with other teams including Peking University and Tsinghua University.

In 1974, direct flights between Beijing and Tokyo were already in operation, so it was possible to fly directly to Tokyo at that time.

In this way, there is no need to go to Hong Kong Island and then go to Tokyo to transfer to San Francisco.

It was Lu Jiaxi and the others' first time on a plane, and they were all very excited.

Before Wang Duoyu boarded the plane, he saw a group of students from Tsinghua University and Peking University greeting him very proactively and enthusiastically.

Many of the faces are familiar, such as Yang Nianzhen, Ding Haiyang and others.

He didn't expect that these people would also go to the United States with him. It seems that Peking University is really rich.

Shiing-Shen Chern was also on this flight. Although he was so old, he often flew and seemed to be in good health.

On the contrary, Duan Xuefu didn't see him.

There are a total team of more than 200 people. It can be seen that the superiors attach great importance to this communication.

The two planes took off from Nanyuan Airport, landed in Tokyo, stayed for ten hours, and then took off again for San Francisco.

When in San Francisco, Wang Duoyu and his group stayed for twelve hours, and then took flights of other airlines across the North American continent and arrived in New York.

After arriving in New York, you can drive directly to the small city of Princeton.

The distance from Kennedy International Airport to Princeton University is actually less than 100 kilometers, so you can drive.

After arriving at the place, Wang Duoyu and his friends just got off the car and saw Zhu Hanting, Jian Xianglan and other international students. They were all very excited.

"Duoyu, you're finally here. I regret coming to America."

After seeing Wang Duoyu, Zhu Hanting couldn't hold back any longer and burst into tears.

Rong Guangxia and Mo Ruogao beside them looked at each other in surprise. They never expected Zhu Hanting to react like this.

You know, last July, Zhu Hanting went to the United States to study, and at that time he was the object of envy of many people.

Even if Zhu Hanting took a long time to adapt to life in the United States after arriving there, it has been almost a year now, so he should have adapted by now, right?

How can we talk about regret?

Wang Duoyu was at a loss for words. Before he could speak, Zhu Hanting pointed at Rong Guangxia and the others and said:
"You're being unfair. Look at them both, they both published papers in the Annals of Mathematics. And look at me? It took me several months to adjust to life in the US, and since then, apart from having a reputation as an American student, I haven't achieved anything."

Zhu Hanting was already a student in the local high school pilot class in 1966. He was only sixteen years old that year.

But this year is 1980, and he is already thirty years old.

For a man, being over thirty and having achieved nothing is the biggest blow.

The reason why his resentment was so deep and why he couldn't hold back his tears was that he had many opportunities to change his fate, but he avoided them all.

Before 1966, he was a child of destiny because he was admitted to the local experimental class, which was a symbol of genius.

Unexpectedly, in 1966, a cold Siberian wind blew, completely shattering his dream of studying at Tsinghua University.

After entering Harbin Institute of Technology, he worked hard and seized the opportunity to study in the United States. He thought it was a highlight moment, but he didn't expect that coming to the United States was a pit. On the contrary, Rong Guangxia and Mo Ruogao, who stayed at Harbin Institute of Technology, both published their papers in the American "Annals of Mathematics".

So what is this?
Every time he picked up sesame seeds and lost watermelons, he demonstrated what it meant to perfectly miss the best opportunity.

God is so unfair to him.

After Zhu Hanting finished speaking, Wang Duoyu, Rong Guangxia, Mo Ruogao and others also fell silent, because they were all members of dormitory 303 and of course they were very familiar with the former's experience.

What can Wang Duoyu and the other two say?

If I say some cheap words of comfort, it would seem like I'm gloating, and Zhu Hanting doesn't need such cheap comfort.

But it seemed unreasonable to say nothing, so Wang Duoyu and the others were also in a dilemma.

After a moment of silence, Wang Duoyu said:
"When I return to HIT, I will continue to teach. If you want, you can apply to come back."

Zhu Hanting has a good talent for mathematics. He was able to successfully publish his paper in the "Journal of Mathematics" of Fudan University through his own efforts. So it would be great if such a talent could come back to Harbin Institute of Technology.

Although Zhu Hanting has been in the United States for a year, it doesn't seem good to give up halfway.

But Wang Duoyu believes that this year's experience will not be wasted. On the contrary, it will be Zhu Hanting's most precious spiritual wealth.

"okay, I get it!"

Upon hearing this, Zhu Hanting was overjoyed. This was exactly the promise he wanted.

This damn thing about studying in the United States, he will never have such an opportunity again.

Holding Wang Duoyu's thigh is better than anything else.

Jian Xianglan was standing by, watching with a complicated expression.

She just had a brief conversation with Xue Xiaoling. Xue Xiaoling was quite humble and looked completely different from how fat she was a year ago.

It wasn't until someone called Xue Xiaoling "Teacher Xue" that Jian Xianglan's smile froze.

She knew that Xue Xiaoling had published a paper in an American professional mathematics journal, but she never expected that Xue Xiaoling had been hired as a teacher at Harbin Institute of Technology.

The transition from student to teacher does not seem so abrupt in university.

However, in the eyes of Jian Xianglan, who has always been very proud, this is a fact that is difficult to accept. Why?
Why?
On the other side, Zhu Chengwu also met Professor Vann Lawrence, who admired him very much.

Fann was so happy that his face was full of wrinkles from smiling.

After a brief welcome, Wang Duoyu and his friends were invited back to the hotel to adjust to the jet lag.

The next night, Wang Duoyu and his friends had almost rested enough before attending the welcome dinner.

An American specialty: dinner parties!

Andre Weil, Charles Fefferman, John Milnor and others all showed up. They were the hosts and welcomed Wang Duoyu and others.

Qiu Chengtong, Smale, Lars Valerian and others also attended the dinner.

Because the lecture was approaching, many people arrived at Princeton University early.

As early as four months ago, Shiing-Shen Chern, Shing-Tung Yau, Smale and other mathematics professors from the University of California, Berkeley, failed to win the right to host this symposium. As the ultimate winner, Princeton University could not wait to announce the good news.

After the news was announced, mathematicians and mathematics enthusiasts all over the world were looking forward to this lecture, simply because it was the ultimate feast for the Poincare conjecture.

The importance of a report meeting that is the final conclusion is self-evident.

After Smale verified the Poincare conjecture for five-dimensional and higher spaces at the 1961 Kiev Conference on Nonlinear Oscillations, a door to truth was opened for mathematicians all over the world.

But it was not until the year before last that Wang Duoyu proved the Poincare conjecture in four-dimensional space. Then he worked non-stop and did not give others any chance at all. After a lecture at Peking University in April last year, he verified the Poincare conjecture in three-dimensional space and even reached the limit.

In other words, all the mathematics professors, PhDs, etc. who studied the Poincare conjecture around the world are dead.

The door opened and then closed again.

Therefore, when Princeton University confirmed the time and place of the lecture, everyone looked forward to that day.

"Professor Wang, something happened!"

Just as Wang Duoyu was communicating with Smel and the others, Wu Congxin came over with Liu Taoshun and the others with a gloomy face, pulled him aside, and told him a piece of bad news:

Someone claimed that there were problems with the three proof papers he wrote last year, and this person would embarrass him at the conference.

After hearing this, Wang Duoyu's face was immediately filled with questions: "Who is this? Why are you trying to scam me at this time?"

He didn't ask Wu Congqin and the others, nor did he care about this matter.

The Poincaré conjecture has been proved, there is no doubt about it.

Even if the paper review editors invited by the Annals of Mathematics are all idiots, Wang Duoyu would not be so bored as to joke about his own reputation.

If there was any punctuation error in any of the three papers published in the Annals of Mathematics, he would eat and swallow the paper.

It's just hilarious!
"Director Wu, ignore these clowns. We'll just pretend we don't know anything."

After a pause, Wang Duoyu continued:

"If the other party really jumps out, I will definitely convince him."

Translated, it means that if the other party dares to make trouble, he will stab the other party's lungs and don't care whether the other party lives or dies.

As the saying goes, one general's success is built on the sacrifice of thousands of soldiers, and this is also true in the field of mathematics.

Whoever is the best is the king of mathematics.

Maybe the opponent is very strong, but Wang Duoyu will definitely be more powerful than him.

The welcome dinner continued and Wang Duoyu was still the focus of everyone.

Jian Xianglan, Li Wanting, Zhou Qingli, Yuanshi County and other international students watched Wang Duoyu, who was younger than themselves, chatting and laughing with Andre Weil, Smale, John Milnor and others, and their back teeth were almost broken.

"You mean that after you return, you will be able to attend Professor Wang's course immediately?"

When Ding Haiyang mentioned the classes this summer, Zhou Qingli, Li Wanting and others immediately became nervous.

"Yes, you may not know this, but this matter was negotiated between Director Duan and Harbin Institute of Technology."

Yang Nianzhen added enthusiastically:
"You may not know this in the US, but four people from Harbin Institute of Technology, Xue Xiaoling, Rong Guangxia, Zhu Chengwu, and Mo Ruogao, have published papers in American journals. Furthermore, over thirty of them have published papers in Chinese journals like Science China and Mathematics."

"Since July and August of last year, we have published over 80 papers in top domestic journals. We have reviewed every single one, and Director Duan says the quality is extremely high."

hiss!
Zhou Qingli, Li Wanting and the others immediately lost their composure and asked in surprise:
"Really that many?"

In just one year, there were more than 80 additional domestic papers, which doesn't seem that great.

But you have to know that this is the class taught by Wang Duoyu, with a total number of less than 70 students, and he only taught the class twice.

Many students who only joined in March this year have not yet finished revising most of their papers.

At the end of August last year, there were only 39 students remaining in the classroom.

And it would be very impressive if ten of these thirty-nine people could fully understand the paper on the Poincare conjecture in four-dimensional space.

It was later proved that only the papers of Xue Xiaoling, Rong Guangxia, Zhu Chengwu and Mo Ruogao were successfully published in the "Annals of Mathematics", which was enough to prove this point.

There are indeed less than ten people!

"Of course, I've read all these papers. Anyway, I can't write one for the time being."

When Yang Nianzhen said this, he was indeed very unwilling in his heart.

But this is the truth, and she certainly can't lie.

If she were asked to write a paper, she might be able to do it, but the quality would be poor.

Following Yang Nianzhen's words, Zhou Qingli and other international students felt a huge wave of emotion in their hearts.

They once again fell into deep self-doubt: Is it right or wrong to come to the United States to study?

No matter what Zhou Qingli and the others thought, Wang Duoyu also encountered a problem at this time. Smale invited him to make an academic visit to UC Berkeley after the lecture.

To be honest, he didn't really want to go.

But it seems that on the way back, we will pass through San Francisco.

San Francisco is very close to Berkeley, less than 30 kilometers away.

So, there seems to be no reason to refuse?
However, Wang Duoyu did not agree immediately, saying that he would decide based on the circumstances at that time. But judging from the current situation, it seems that he will most likely have to visit UC Berkeley.

In addition to Smale, Andre Weil, on behalf of the Institute for Advanced Study at Princeton, invited Wang Duoyu to become a researcher at the institute.

"Andre, I'm not a doctor yet. I don't meet your requirements, right?"

Wang Duoyu widened his eyes and asked in confusion.

What is the Institute for Advanced Study at Princeton?
Even a great man like Shiing-Shen Chern was invited by American mathematician Oswald Veblen to work as a researcher at the Institute for Advanced Study in Princeton in 1943.

At this time, Chen Shiing-Shen was already famous. He was a mathematics professor at Southwest Associated University, teaching differential geometry courses.

This institute was founded in 1930. Every researcher is a top expert in his field, and the School of Mathematics is the most powerful.

Former researchers include Albert Einstein, John von Neumann, Kurt Gödel, Robert Oppenheimer, etc., making it a world-famous academic sanctuary.

After joining the institute as a researcher in 1944, Shiing-Shen Chern published epoch-making papers in just two years: "A Simple Intrinsic Proof of the Gauss-Bonnet Formula for Closed Riemannian Manifolds" and "Characteristic Classes of Hamiltonian Manifolds".

It was these two papers that established his position in the history of mathematics.

"Professor Wang, the fact that you've published four papers on the Poincare conjecture is enough to prove your ability. You've already surpassed many researchers at the Institute for Advanced Study in Princeton."

Andre Weil praised.

The first half of this sentence is true, but the second half is debatable.

Wang Duoyu knows his own limitations, and he doesn't want to stay in the United States.

If the International Congress of Mathematicians had not been held so soon, he would not have come to Princeton University to give a report.

He did not immediately reject Andre Weil's invitation, but said he needed to think about it.

Saying that he was considering it was actually a polite refusal.

We are all smart people, and I believe Andre Weil can hear it.

But this time, Andrei Weil pretended to be deaf and dumb, and happily said that he would wait for good news.

These words almost made Wang Duoyu roll his eyes.

After the dinner, the report meeting officially began the next morning.

The largest auditorium at Princeton University is packed today, with many more people attending the lecture at Peking University last April.

First of all, Princeton is the center of mathematics in the United States and one of only two centers of mathematics in the world.

Therefore, holding a lecture here naturally has great appeal to many mathematics enthusiasts.

Second, this report is the final report on the Poincare conjecture, which is of great significance and can even be said to be one of the greatest reports of this century.

Sitting at the front of the auditorium were big names like Shiing-Shen Chern, Smale, John Milnor, and Andre Weil, while Yang Nianzhen, Jian Xianglan, Xue Xiaoling and others were sitting in the middle.

Xue Xiaoling, Rong Guangxia, Mo Ruogao and others came here this time purely to see the world. It is hard to say whether they can learn anything.

As an independent researcher, this was Lu Jiaxi's first time attending such a high-level conference. Over the past few days, he had gained a lot of knowledge.

The relatively troublesome thing is that he needs an interpreter.

Fortunately, he does not need a special translator, and ordinary translators may not be able to translate it.

Whether it is Jian Xianglan or Zhu Hanting, they are both very ready-made translators, and with their mathematical level, they can still translate relatively accurately, allowing Lu Jiaxi to communicate smoothly with these foreign mathematicians.

The time soon came to nine fifty, and Wang Duoyu sat in the waiting room, waiting quietly.

He was not nervous at all, and he was even writing a novel half an hour before the lecture started.

This time, starting from Harbin Institute of Technology, he started writing a new novel, or to be more precise, copying a novel.

I used to copy novels for a living, but now I copy novels to live up to my readers and to repay the appreciation of old lady Zhou Yanru.

I use my free time to write some novels, which also helps my mind relax and not be so tense.

At ten o'clock in the morning, Wang Duoyu walked onto the podium under the guidance of the staff.

The huge crowd below the stage, with more than two thousand pairs of eyes staring, all of them focused their attention on Wang Duoyu.

“Good morning, friends from all over the world. It’s a pleasure to meet you here at Princeton University.”

After taking the stage, Wang Duoyu smiled and said in a confident and calm tone:
"Today's lecture will be divided into two sessions, morning and afternoon. The morning session will focus on the two papers on the Poincare conjecture in three-dimensional space, and the afternoon session will focus on the final capping paper. Okay, let's officially begin now."

As soon as he finished speaking, someone raised his hand to ask a question, but there was no microphone, so he had to speak very quietly.

A large auditorium with more than 2,000 people is a very spacious place, so it naturally requires a higher decibel level or a microphone to transmit sound.

"Now is not the time for questions. Please take a seat."

Wang Duoyu ignored the other party and started talking directly.

First, let me explain the Poincare conjecture: in a three-dimensional space, if every closed curve can be contracted to a point, then this space must be a three-dimensional sphere, that is, any single-connected three-dimensional closed manifold is homeomorphic to the three-dimensional sphere.

In fact, this means that any closed object in our three-dimensional space, whether it is a brick, a person, or a tractor, as long as it is closed, can be continuously transformed into a three-dimensional sphere in four-dimensional space.

In other words, just as the boundary of a three-dimensional sphere is a two-dimensional closed sphere, the boundary of a four-dimensional sphere is actually a three-dimensional closed sphere.

If you remove a point from this sphere and expand it, you get the entire three-dimensional space. Any closed object in this three-dimensional space can be turned into a three-dimensional closed sphere by stretching, bending, and extending.

"A structure like the trefoil knot can't be transformed into a sphere in three dimensions, but in four dimensions, such a transformation becomes easy."

"Please look at page 30 of the paper, which details the mathematical tool L-function, one of the best ways to deal with manifold singularities."

In fact, L-function is a very big topic.

In December of the previous year, Wang Duoyu wrote thirteen mathematical papers while promoting the Langlands idea. One of them was "Using harmonic analysis to study important L functions in number theory and reconstruct class field theory."

In this paper, Wang Duoyu mentioned this point for the first time, but he only applied the L function very simply.

If you want to understand the mathematical tool of L function, reading this paper will only make you more confused.

However, the L-function is a tool that allows time to travel freely between the past and the future, so that when the singularity collapses, time can go back to the past, thereby controlling the singularity.

In Wang Duoyu's calculations, even if time goes back to the past, it will not have much impact.

According to his prediction, the vulnerability that malicious people want to attack is most likely the so-called L function.

Because this concept is too mysterious, it seems to confirm the saying: the end of science is metaphysics.

However, in the world of mathematics, everything can be expressed using mathematical symbols, which means it can be calculated.

Wang Duoyu has calculated the L function, and Smale, Qiu Chengtong, John Milnor, Hirzebruch and others have all calculated it, and there are no problems.

If there were any problems, Wang Duoyu would not be standing here to give a report today.

Those so-called clowns, who thought they had grasped the truth, came to disrupt this report meeting. What a pipe dream.

There are two papers on the Poincare conjecture in three-dimensional space, and the report time for each paper is one hour.

In fact, Wang Duoyu only wanted to finish presenting the three papers within an hour, but Princeton University hoped that he could give him more time.

It is true that concentration is the essence, but if it is too concentrated, then many things cannot be explained.

This time, there was no rush at all. After all, it was not an International Congress of Mathematicians, and everyone had plenty of time to listen to Wang Duoyu's report.

In this case, if each paper takes one hour, more people will be able to understand it. Isn’t that great?

Xue Xiaoling, Rong Guangxia, Mo Ruogao, Zhu Chengwu and others have already attended very detailed courses and have thoroughly understood the three papers.

However, even so, Wang Duoyu still feels that his brain is not enough when he is giving a report.

Just because Wang Duoyu spoke too fast.

Starting from March, Wang Duoyu would spend two hours every Monday to Friday evening to teach these three papers, and the two days on the weekend were their own time to digest the knowledge.

It can be said that it was very detailed, and the paper was chewed up and fed to them step by step.

But they can't digest it completely.

Just as their stomachs find it difficult to digest hard foods like walnuts, these papers are like hard stones that are difficult for them to digest.

If they hadn't digested it before, now it would be like fast-forwarding a hundred times, making it even harder for them to keep up.

Yang Nianzhen widened his eyes, pricked up his ears, and listened attentively, but he heard nothing.

In the past, she always thought that she was a top student, or even a genius, but after listening to Wang Duoyu’s lectures and reports, she began to doubt her life.

In the past, she didn’t understand why those poor students didn’t study, but now she understands.

The big guys in the front row all listened very carefully. They could understand and their brains could keep up. They didn't need to think about many of the points mentioned by Wang Duoyu to understand them.

The brains of the big guys are like a supercomputer, processing data quickly and accurately.

As time goes by, the report meeting is coming to an end.

"Okay, we've finished discussing the two papers on the Poincare conjecture in three-dimensional space. We'll discuss the final paper at 2 p.m., and the next half hour will be for questions."

When Wang Duoyu's words were heard, the audience burst into thunderous applause and everyone was very excited.

But at this time, someone had already raised his hand, eager to find fault, er, to ask a question.
