Chapter 284 The dream longed for for thousands of years [Subscribe]

"This is the list of selected team members. Once it is announced to the public, please notify them as soon as possible."

At the editor-in-chief's office at the Editorial Committee headquarters of the Chinese Journal of Mathematics, Xu Yuangang pushed the door open and handed the document in his hand to Ma Zhiming, adding these words of advice at the end.

After several days of review, he finally successfully selected people who were suitable to join the Riemann hypothesis research team.

So I came here quickly, thinking of sending out the list as soon as possible.

It would also be better to complete the formation of the team as soon as possible.

Officially began research on the Riemann hypothesis.

This is also thanks to him. After entering the deep learning state, he is highly focused and concentrated on everything he does.

Has super high efficiency.

Otherwise, it would probably take a long time just to review these test papers.

Originally, there was no rush to study the Riemann hypothesis. After all, it was the world's number one mathematical problem.

To prove something thoroughly, one needs inspiration.

But he received an email from Deligne, in which he learned that the Clay Mathematics Institute and the International Mathematical Union had also formed a Riemann hypothesis research team.

And he expressed his intention to prove the Riemann hypothesis before him.

It was obvious that they were coming for a challenge, targeting him.

The more this situation occurs, the more we must not let the other side take the lead.

Otherwise, his reputation as a mathematical master would be affected to some extent.

Although he is very confident in himself, the level of overseas mathematicians should not be underestimated.

Especially Fields Medal winners like Terence Tao have chosen to join in and participate in the research.

This will more or less bring him some pressure.

After it is transformed into motivation, I will definitely be more proactive in the research of Riemann hypothesis than before.

Ma Zhiming was writing something on his desk. When he noticed that it was Xu Yuan, he immediately stopped what he was doing, stood up, and first warmly asked him to sit down, then reached out to take the document. He seemed to be surprised that Xu Yuan had chosen the research team members so quickly, and his face showed a little surprise.

"Have all the test papers been reviewed?"

I just said this subconsciously, and soon I remembered that Xu Yuan was indeed efficient.

He immediately regained his composure, sat back in his chair, and opened the document to look at the list on it.

As his eyes fell on the document, several names immediately came into view.

Some of them are familiar.

But at this time he seemed a little regretful, and the next second he raised his eyes and looked towards Xu Yuan in front of him.

I couldn't help but ask, "Did you only choose five people?"

As the editor-in-chief of the Journal of Mathematics and chairman of the Mathematical Council, Ma Zhiming naturally knows what this opportunity means.

Regardless of whether the Riemann hypothesis can be successfully proved in the end, one can learn a lot just by following Xu Yuan.

It will help train top mathematicians for the country that are not inferior to those overseas.

Increase the foundation of the domestic mathematics community.

Considering this aspect, he certainly hopes that as many candidates as possible will be selected.
After all, Xu Yuan has never supervised any graduate or doctoral students since he was elected professor of the School of Mathematics at Qinghua University. It would be good to have this opportunity to teach more outstanding mathematicians.

But in the end, only five people were selected.

It was actually much less than he had expected.

Xu Yuan naturally understood what Ma Zhiming was thinking from his tone, and he had known about this matter for a long time.

However, the original intention of establishing the research team this time was mainly to try to thoroughly prove the Riemann hypothesis.

Promote the development of mathematics.

Training outstanding mathematicians for the country can only be a side job.

What’s more, there is pressure from the overseas mathematics community at present.

Therefore, it is obviously not a wise choice to hastily attract unsuitable people into the research team.

It might slow down the progress of the entire research team.

It is not even an exaggeration to say that even for these five people, he had lowered the threshold a little.

Otherwise the number would be even smaller.

"These few people are enough. If there are more, it will have the opposite effect." Xu Yuan replied with a smile.

Although Ma Zhiming felt regretful, he had no objection to Xu Yuan's decision.

Besides, it was Xu Yuan who originally proposed to set up this research group.

If Xu Yuan still chose to study the Riemann hypothesis alone, even these five people would not be able to find such an opportunity.

"Five is five."

He nodded and responded in a deep voice, then turned his gaze to the list on the document.

After noticing the familiar name, a faint smile appeared on his face.

"As expected, Tian Zhen was selected. I said he has some talent in mathematics."

He did not hide the affection he showed when he spoke.

Xu Yuan naturally knew the five selected people very well, and he was even more familiar with Tian Zhen mentioned by Ma Zhiming.

The other person was about the same age as him, only in his thirties.

And the experiences are quite similar.

They all won gold medals in competitions during high school, and published valuable academic papers during their undergraduate and graduate studies.

After graduation, he chose to stay in school and later became an associate professor at Yenching University.

After the Hodge conjecture was proved, he successfully used topology to prove a difficult problem in algebraic geometry by citing the Xu-Hodge theorem.

With this success, he won the first Xu Yuan Mathematics Award.

Now he is a full professor in the Department of Mathematics at Yenching University.

Although there is still a big gap compared with Xu Yuan, he can indeed be called a mathematical genius compared with other places.

It is a height that many people cannot reach.

Speaking of which, it was Xu Yuan who personally presented the award to the other party.

I didn’t expect that a few years later, we would have the opportunity to work together on research and proof of the Riemann hypothesis.

For this reason, Xu Yuan did not hesitate to praise Tian Zhen.

"He has real talent and mathematical thinking skills, and his grades are the highest among those who signed up."

Upon hearing this, Ma Zhiming's smile became even brighter.

Who made him graduate from Yenching University?

In the following period of time, Ma Zhiming did not delay too much. He immediately arranged for someone to publicize the list and contact the selected candidates.

So that they can finish the report as soon as possible and come over to officially start the research.

In order to ensure that the proof of the Riemann hypothesis can be fruitful and to provide the research team with a quiet and undisturbed environment, Ma Zhiming and Xu Yuan, after discussion, selected an area at the headquarters of the Journal of Mathematics as the group's activity area.

During this period, he will not accept interviews from any news media until he successfully proves the Riemann hypothesis.

When Ma Zhiming and Xu Yuan were still alone in the office, Ma Zhiming invited Xu Yuan to sit on the sofa next to him.

I made a pot of tea myself.

After pouring a glass for Xu Yuan, they started chatting.

"This time, overseas countries are competing with us in mathematics and have set up a research team to prove the Riemann hypothesis. What do you think about this?"

"Are you stressed?"

At present, the whole world is paying attention to the fact that overseas companies are trying to compete with them.

Mainly because China had just lost face and suffered losses in the international arena due to the Dongfeng hypersonic missile, the first counterattack it launched was the mathematical academic competition.

Naturally, everyone wants to see whether America can turn the tables now that the battlefield has been moved to the world of mathematics.

Logically speaking, under such circumstances, those responsible for studying the Riemann hypothesis should be under a lot of pressure.

After all, with so much attention on the issue, it would be embarrassing for any party that fails to solve the Riemann hypothesis first.

Xu Yuan naturally understood that Ma Zhiming was concerned about him, so he picked up the teacup in front of him and took a sip before answering the question in a nonchalant manner.

"It's impossible to say there's no pressure at all, because there are many Fields Medal winners there. They also have many more mathematicians than we do, so they definitely have enough talent."

"But I am confident that I can prove the Riemann hypothesis once and for all."

When he spoke the last sentence, he was very decisive.

With confidence.

Ma Zhiming, who was originally a little worried, smiled even more brightly after hearing these words.

"With your words, Academician Xu, I feel relieved."

"It seems that it won't be long before we hear the good news that the Riemann hypothesis has been proven in the mathematics community."

He has been in contact with Xu Yuan for such a long time and he has great faith in Xu Yuan's confidence.

I am not afraid of Xu Yuan’s confidence, I am afraid of his lack of confidence.

Because the final result will basically not change.

In the following time, the two continued chatting for a while, and Xu Yuan did not stay any longer.

He stood up, said goodbye and left quickly.

The Space Technology Research Institute needs him to go over there, and no matter what the matter is, he must not be delayed.

Not to mention that he also serves as a researcher at the Space Technology Research Institute, just because his father-in-law Chen Jianfang spoke, he had to go.

Just when he left the School of Mathematics and Systems Science and went to the Institute of Space Technology, the list of people selected for the Riemann hypothesis research group was officially announced online.

Originally, netizens were a little worried that the research team members would hinder Xu Yuan.

But after seeing that only five people were selected, and all of them had good academic achievements in mathematics.

This worry soon turned into expectation.

I hope the research team can work together sincerely to prove the Riemann hypothesis and learn more from Xu Yuan, so that the domestic mathematics community can have more top mathematicians.

Otherwise, when outsiders mention the domestic mathematics community, the only name that comes to mind is Xu Yuan.

That is also not a true rise.

"Only five people were selected. I thought they would compare with overseas candidates. It seems that Academician Xu has indeed thought it through carefully."

"These mathematicians are all very good, and some of them even won the Xu Yuan Mathematics Award."

"Starting to look forward to it."

“Although we don’t have as many people as overseas research teams, when it comes to proving the world’s most difficult mathematical problems, we can just trust Academician Xu.”

"The list is out so quickly. How efficient!"

"Are we finally going to start studying the Riemann hypothesis? I hope there will be good news soon."

"I hope these mathematicians can learn more from Master Xu. We still have too few top mathematicians."

"I really wasn't selected as I wished. It's such a sad story."

……

at the same time.

In a tiered classroom of the Department of Mathematics at Yenching University, no less than two hundred students were gathered in the classroom, listening attentively to an open mathematics class being given by a tall young man wearing a pair of glasses on the podium.

Although the content is relatively difficult complex functions, it is rare to see students playing with their phones or drowsiness.

His face showed seriousness and concentration.

As the youngest full professor in the Department of Mathematics at Yenching University, Tian Zhen is deeply loved by students in the school because of his mathematical talent and humorous personality.

It is even said that Yenching University has its own Xu Yuan.

This shows how highly his mathematical level is evaluated.

"Does anyone have any questions? Please speak up now and we can discuss solutions together."

At this time, Tian Zhen finished writing the last mathematical symbol on the blackboard, turned around and asked the students below the stage.

Just as the students were thinking about the questions to ask.

But a boy sitting in the middle seat suddenly seemed to be stimulated by something. The next second, he slammed the table and stood up like a spring, shouting excitedly to Tian Zhen on the stage.

"Professor Tian, ​​you have been successfully selected into the research team."

This statement immediately attracted the attention of others. They ignored the class they were in and took out their mobile phones to search the Internet.

Even if you are not a mathematics student, if you can sign up for this open course, you must be interested in mathematics.

Therefore, it was very clear that Xu Yuan wanted to form a research team to try to prove the Riemann hypothesis.

Even been paying attention.

At the same time, I also learned that my own professor Tian Zhen had also signed up for the exam.

And it turned out that what the boy said was right. When everyone saw the hot search at the top of the list, they immediately saw Tian Zhen's name in the public list and easily found it.

Then, warm cheers immediately rang out in the entire classroom.

Everyone was happy that Tian Zhen had such an opportunity.

"Professor Tian is indeed on the list, and his score is the highest."

"Congratulations, Professor Tian."

"I've already said that with Professor Tian's ability, there will be no problem signing up. Now you can see that you have successfully joined the research team."

"This is a great joy."

“It is such a pleasure to study the Riemann hypothesis with Academician Xu.”

"Academician Xu has really made great progress. He can actually study the Riemann hypothesis with our Professor Tian."

"What rebellion against Tiangang!"

At this moment, Tian Zhen was standing on the podium, listening to the discussions in the classroom, and he himself was a little surprised.

I didn't expect that I would be so lucky to be able to do research with Xu Yuan.

"I...I was selected!"

As he stood there whispering, the expression on his face was quickly replaced by surprise.

As a qualified mathematician, although his age is not much different from Xu Yuan, he admires and respects Xu Yuan very much, especially because the other party, at the age of less than 30, completely solved and proved the Hodge conjecture on his own.

He became a world-recognized master of mathematics, which made many domestic mathematicians proud.

He could have become a professor in the Department of Mathematics at Yenching University and received a mathematics award personally presented by his idol.

He was already very satisfied.

I don’t expect to be able to prove the world’s most difficult mathematical problems like Xu Yuan did.

After all, he was well aware of the gap between himself and Xu Yuan.

In the future, I will be able to teach students well and cultivate more excellent new blood for the domestic mathematics community, which will be worthy of my professorship. But I never expected that Xu Yuan would set up a research team to try to prove the Riemann hypothesis.

When he first heard the news, he had a strong idea in his mind.

I thought this might be a good opportunity for me.

Absolutely not to be missed.

So he decisively chose to sign up and set aside time to complete the test paper released on the official website.

It turned out that his choice was not wrong and he was successfully selected into the research team.

Become a member of Xu Yuan's team.

If you participate in the proof project of the Riemann hypothesis and eventually complete the entire proof.

This was undoubtedly a huge change in his mathematical career.

He is expected to grow into a master of mathematics.

Although this is still a long way from him at the moment.

The thought stayed here, and when his mind was working quickly, he saw a middle-aged man standing at the door of the classroom.

He was waving at him.

"Professor Tian."

"Come out for a moment. The department has some news to tell you."

After noticing it, he turned his head to look at the door, and his face was suddenly shocked when he saw the other person's figure.

"Department Head!"

Unexpectedly, it was the director of the department who came to visit.

But he soon realized that it was probably because he was selected to join the Riemann hypothesis research group.

Then he realized what was happening and walked towards the door.

"Good director."

After the figure completely left the classroom, the students inside became more and more excited and happy for their teacher.

-

Xu Yuan didn't know that because of the list of research team members, many people were filled with great joy.

At this moment, he had already arrived at the Space Technology Research Institute. While greeting the acquaintances he met, he walked straight to the office of his father-in-law Chen Jianfang.

Since the Tiangong space station was completed and put into use, the China Aerospace Science and Technology Corporation and the National Space Administration have focused on the manned lunar landing, a key project that the public is extremely looking forward to.

In addition to fully developing a new generation of launch vehicles, a new generation of manned spacecraft and a new generation of lunar landers.

There are also plans to conduct lunar soil collection experiments to accumulate relevant experience for future manned lunar landings.

Due to the heavy workload and the need for various technological upgrades, researchers at the subordinate Space Technology Research Institute and Shanghai Aerospace Technology Research Institute have become busier.

Under normal circumstances, Xu Yuan is a researcher at the Space Technology Research Institute.

They should also participate in aerospace research projects.

But he has several duties and needs to solve the difficulties the country faces in the semiconductor industry as soon as possible.

The number of visits to the Space Technology Research Institute is much less frequent.

In other words, he doesn't have any important projects on hand now and has relatively ample time, otherwise he might not be able to make it over to listen to his father-in-law Chen Jianfang talk about things.

Of course, although he has been here less frequently recently, he is still very familiar with the Space Technology Research Institute.

Especially Chen Jianfang’s office.

Just as Xu Yuan walked into the building and was about to get on the elevator, he suddenly saw a familiar figure when the elevator door opened.

It was his first time here, and he came down to pick up his senior brother Xiao Xinbin.

When I saw him again, I didn't think too much and just called him "senior brother" as I did before.

"Senior Brother Xiao."

Xiao Xinbin obviously didn't expect to meet Xu Yuan by chance, and a look of surprise immediately appeared on his face.

But after hearing Xu Yuan's address to him, he quickly smiled and responded:

"Academician Xu, you can just call me by my name."

When he was still an assistant researcher, Chen Jianfang arranged for him to go downstairs to pick up Xu Yuan.

He had studied mathematics as an undergraduate and later switched to other fields, so he admired Xu Yuan, a mathematical genius. But he did not expect that after all these years, although he had become an associate researcher, Xu Yuan was already an academician of the two academies who had won the highest science and technology award.

The two people are completely on different levels.

In this case, even if Xu Yuan didn't care about these things, it would still be inappropriate for the school to call him senior brother.

When Xu Yuan heard what Xiao Xinbin said, he immediately realized something.

Then a smile appeared on the corner of his mouth, and he reached out and patted the other person's arm to greet him again.

"Researcher Xiao, we haven't seen each other for a long time. How about we find a place to have dinner tonight?"

Hearing Xu Yuan's address, Xiao Xinbin immediately smiled and agreed without hesitation the next second.

"That's what I want."

"As long as you have time, Academician Xu, I can do it anytime."

After he finished speaking, he suddenly realized something and immediately asked, "By the way, are you here to see Academician Chen?"

"Academician Chen and Academician He from the Magic City Aerospace Technology Research Institute are holding a technical demonstration meeting in the conference room. It's probably too early for the meeting to end. Otherwise, I'll take you there directly."

Xu Yuan listened to everything Xiao Xinbin said and was a little surprised.

Unexpectedly, He Luping from the Shanghai Aerospace Technology Research Institute was also there.

When the two of them held a technical discussion meeting and asked me to come over, I could basically guess what was going on without thinking.

In all likelihood, he will need your help.

His thoughts stayed here, and he didn't say anything more. He nodded and said to Xiao Xinbin:

"Then I'll trouble Researcher Xiao."

"It's a small matter." Xiao Xinbin replied with a smile and walked back into the elevator.

Because the meeting place was also in this building, it took only a few minutes after the two came out of the elevator that they were led by Xiao Xinbin to the door of the meeting room.

You can even faintly hear the sound of quarreling coming from inside.

However, Xu Yuan does not think there is anything wrong with this. On the contrary, arguing is a very normal thing for scientific researchers.

After all, the truth becomes clearer the more it is debated.

"The place where Academician Chen is holding the meeting is inside. You can just go in directly."

"Thank you."

Upon hearing this, Xu Yuan thanked Xiao Xinbin, and after watching him turn around and leave to do his own thing, he naturally did not hesitate any longer. He first raised his arm and knocked on the door of the conference room, and then pushed the door open and walked in without waiting for the person inside to answer.

As my vision is updated, the first two people who come into view are Academicians Chen Jianfang and He Luping.

Then there is Professor Gao Duo from the Institute of Space Technology.

Although the other few people seemed a little unfamiliar, they should all be researchers from the two institutes.

Chen Jianfang was the first to react when he saw the person coming. He quickly stood up and greeted him warmly.

"Xiao Yuan, you are here, please sit down."

He Luping, who was standing next to him, had a smile on his face and quickly took over the conversation and echoed the others.

"It's not easy to invite you here once."

Gao Duo, on the other hand, spoke up for Xu Yuan: "There's nothing we can do about it. Our great academician is so versatile that everyone wants to invite him to participate in the research and development of key projects." As he finished speaking, he deliberately glanced at Xu Yuan.

Xu Yuan listened to everything they said, and he was feeling both amused and sad, not knowing what to say.

Professor Gao Duo was fine, but Chen Jianfang and He Luping were obviously a little angry with him.

Complaining that he hadn't paid much attention to aerospace affairs during this period.

But facing these two people, he naturally had no temper at all, so he had to respond quickly.

"If you have any questions, please tell me directly. I will definitely do my best to do what I can."

The voice just fell.

Then smiles immediately appeared on the faces of several people.

"Your words are more pleasing to the ear." He Luping nodded, looked at Chen Jianfang beside him and said, "Then let Old Chen tell you about it."

Naturally, Chen Jianfang had already prepared for this. After handing a stack of documents to Xu Yuan, he spoke in a deep voice about the details.

"I called you here today because I want your help."

"At present, our design research on the next-generation launch vehicle, the next-generation manned spacecraft and the next-generation lunar lander is not going very smoothly."

"There are certain design flaws in both the rocket engine and the thermal control system."

“The materials used also need to be upgraded.”

……

Xu Yuan took the information from Chen Jianfang, opened it and read it carefully while listening to his story.

After talking for nearly ten minutes, he finally had a general understanding of the situation.

It is basically impossible to achieve manned lunar landing with the existing Long March rockets and Shenzhou manned spacecraft technology.

The moon is 38 kilometers away from the earth. To achieve manned flight and successful landing on the moon, the total payload that needs to enter the lunar orbit must reach 50 to 100 tons.

However, the largest launch vehicle in service has a lunar orbit carrying capacity of less than ten tons, which is limited by its takeoff size, power system performance, structural efficiency, etc., and is simply unable to meet the needs of manned lunar landing.

A new generation of launch vehicles must be designed and researched.

Ensure that it is capable of sending the lunar lander and manned lunar spacecraft into the Earth-Moon transfer orbit.

This places very high demands on the rocket's engine design.

In addition to the complex environmental changes on the lunar surface, it is also necessary to ensure the safety of the lunar lander's thermal control system and that the material properties meet the requirements.

In short, it is indeed not an easy task to truly complete the design of a new generation of aerospace technology.

The Space Technology Research Institute and the Shanghai Aerospace Technology Research Institute are working together to design the plan.

Ultimately, the desired effect was not achieved, so the plan was delayed in being formally passed.

This directly affects the timing of manned lunar landing.

Manned lunar landing has been a dream that the Chinese people have been pursuing for thousands of years.

It is also a comprehensive reflection of the scientific and technological level and national strength of a world power.

For astronauts, they certainly hope that this day can arrive soon and not let the public down.

Previously, Xu Yuan was in charge of the research and development of the lithography factory and had no way to directly participate in the design of the new generation of spacecraft. Now that he has time, Chen Jianfang naturally wants to find him quickly.

Although Xu Yuan designs aircraft engines, they can also be used on rocket engines.

With the progress bar on the panel in front of you, it should be no problem to find loopholes in the solution and help optimize and upgrade it.

It takes some time at most.

The key point is that he is a researcher at the Space Technology Research Institute, so he can't refuse such a project.

After thinking through these things quickly, he temporarily put the documents in his hand on the table, then met the gazes of everyone present, and nodded in the affirmative.

"Do not worry."

"I am also an astronaut, so I naturally hope to see our astronauts leave footprints on the moon as soon as possible."

"Regarding the next generation of spacecraft, I will come up with a plan as soon as possible."

As Xu Yuan finished speaking, Chen Jianfang, He Luping, and Gao Duo next to him seemed to be relieved.

The frown that was caused by the new generation of spacecraft plan can finally be relaxed.

He Luping was unwilling to waste the rest of the time.

He quickly found a design plan for a new generation of lunar lander and took Xu Yuan to discuss it in detail.

Since Xu Yuan had agreed to participate in the design of the new generation of spacecraft, he naturally would not hide anything at this time, and he shared some of his design concepts and plans during the discussion.

From time to time, you can see surprise quickly appear on a few people's faces, and a feeling of sudden enlightenment.

At the same time, he felt quite regretful. If Xu Yuan could have been allowed to participate in the design of the new generation of spacecraft earlier, perhaps it would have entered the R&D and manufacturing stages long ago.

This will also help realize the Chinese people’s thousand-year dream sooner.

that's it.

The discussion lasted until lunchtime, but some people felt hungry and so they reluctantly stopped.

Judging from the expressions on He Luping and the others’ faces, they had obviously gained a lot.

When several people were preparing to go to the restaurant for dinner, Chen Jianfang thought of something and casually asked Xu Yuan.

"Oh, there's one more thing."

"Next month, a lunar probe will be launched to conduct the first lunar soil collection and return test."

“You must come and watch then.”

Xu Yuan knew clearly that the lunar soil collection and return experiment was a prelude to manned lunar landing.

If a major space power cannot even collect lunar soil, it will be even more impossible to complete a manned lunar landing.

Therefore, the first collection and return of lunar soil is also very important.

Under the attention of the whole world.

Ever since the Tiangong space station was completed in a short period of time and the manned lunar landing plan was announced to the public, many people around the world have been looking forward to this day.

If any problems occur during the lunar soil collection test, it will undoubtedly be a major space accident.

Thinking that he had no other important projects to undertake except proving the Riemann hypothesis, he nodded and agreed without hesitation.

"I'll be there."

However, Gao Duo, who was following next to him, was a little worried. He moved his lips slightly and asked another question.

"I heard that you were going to study and try to prove the Riemann hypothesis, and you even formed a research team for this purpose."

“Will this not affect your other work?”

"I saw on the news that people overseas are eager to prove the Riemann hypothesis before you."

He Luping and Chen Jianfang obviously didn't have a very clear understanding of matters in the field of mathematics. After hearing what Gao Duo said, they all looked at Xu Yuan with concern.

Xu Yuan still looked relaxed about this, and the next second he took over the conversation and replied with a smile:
"Don't worry about the math. I can form a research team to study the Riemann hypothesis, and I'm confident that I can prove it thoroughly."

He spoke in a nonchalant manner, not taking the worry to heart at all.

Upon hearing this, Chen Jianfang and He Luping all thought of Xu Yuan's achievements in mathematics. It is no exaggeration to call him the number one mathematician in the world today.

There is really no need to worry about proving the Riemann hypothesis, something in the realm of mathematics.
