Great Country Academician

Late at night, a bright moon hangs high on the branches.

After hanging up the video call, Xu Chuan stood up and stretched. After stretching, he went to the bathroom to wash his face and sat back at the desk again.

The proof of the polynomial decomposition problem of large positive integer factors is undoubtedly one of the top conjectures in the field of mathematics.

Regarding the P=NP? problem, the mathematics community and the computer community have done a lot of work on this problem for hundreds of years, but there has been no major breakthrough.

Today, in the hands of that senior, he saw a brand new answer, which was undoubtedly satisfying.

However, for Xu Chuan, what concerns him is not just the proof of the polynomial decomposition problem of positive integer factors, but also the method used to solve this problem, or the mathematical tools created by Liu Jiaxin!

He always felt that the targeted decomposition and screening method had far more uses than this.

After putting aside the scattered papers and used manuscript papers on the table, Xu Chuan took a stack of new, unused manuscript papers from the upper right corner of the desk.

He held the ballpoint pen with half of the ink left in his right hand. He stared at the white paper and pondered for a while before writing the first line of formulas.

[ζ(p, s)=ζ(s)·(1-p^s)=∑p|n·1/n^s]

This is one of the main research results of Professor Schultz, a mathematician who won the Fields Medal with him in 2018.

Referred to as the p-adic ζ function, it is a continuous function on Zp, and its value at a negative integer can be represented by the interpolation of a leading polynomial of Zp[T], which mainly reflects the analytical properties of the corresponding number field.

In addition, it is also an important module of Iwasawa theory and plays a very important role in the research of number theory and arithmetic algebraic geometry.

But today, what he wants to study is not Iwasawa theory and algebraic geometry. Instead, we tried to find ways to integrate the analytical properties of this function into the mathematical tools used by Liu Jiaxin in solving the problem of polynomial decomposition of large positive integer factors.

He vaguely felt that if he could do this, maybe he could make a little progress towards the Riemann Hypothesis!

This was what kept him up late. Even if he had to talk to the old man about the future of technological development tomorrow, he wouldn't be able to care so much.

After all, it would be a pity if inspiration and ideas are not caught in time.

Lines of calculations were completed on the white manuscript paper. Facing the breeze outside the window that brought in a little bit of refreshment and a little bit of coolness, Xu Chuan kept thinking about ways to integrate the two tools.

He was very fortunate that he didn't drink much alcohol tonight, or should be said at last night's celebration party, and he still had a clear mind.

Otherwise, you will definitely miss this great opportunity.

I don't know how much time has passed. Just as Xu Chuan was staring at the calculations on the manuscript paper and thinking about it, the cell phone on the table rang.

Frowning subconsciously, he reached for the phone without raising his head, unlocked it and glanced at the screen.

The person who sent him the message was a life assistant.

"Professor, although I don't want to disturb your research, it's already very late now. I have a trip to Chang'an Avenue tomorrow morning, so I hope you can rest early."

Seeing the information on his cell phone, Xu Chuan was stunned for a moment and looked at the time on the screen. Unknowingly, it was almost one o'clock in the middle of the night and almost two o'clock in the morning.

"knew."

He tapped the screen twice with his fingers, replied to a message, and then began to organize the files on the desk.

If it were normal times, he wouldn't mind staying up late or even staying up all night, but it was really not possible today.

After all, I have to go to the North Sea island tomorrow morning.

Fortunately, he has already sorted out some general preliminary ideas. Once the inspiration is in hand, he no longer has to worry about it running away.

The next day, around nine o'clock in the morning. Following the guards, Xu Chuan came to the small island in Beihai on the north side of Chang'an Street again. Passing through the tree-lined path, the familiar two-story building caught his eye again.

As soon as he entered the hall, a smiling voice came to his ears.

"Academician Xu is here, have you had breakfast?" The old man who had been waiting here for a long time saw Xu Chuan's figure and stood up with a smile to greet him.

Xu Chuan greeted him respectfully and responded with a smile: "I've eaten."

After smiling and exchanging pleasantries, he and the old man sat down on both sides of the guest chairs in the hall.

But as soon as his butt landed on the soft chair, Xu Chuan couldn't help but yawn.

Although he finished his study of mathematics before two o'clock in the morning, it was obvious that he could not fall asleep immediately after seeing a wonderful paper and gaining some new mathematical inspiration.

It's just like ordinary people playing games or watching movies, but when you are having a great time or watching something exciting, it suddenly interrupts you and tells you to go back to sleep, and you will definitely not be able to sleep.

He was the same, tossing in bed until after three o'clock or even almost four o'clock before falling asleep.

So much so that after I woke up at around 8 o'clock this morning, I took a cold shower to refresh myself. Now my butt was touching the soft cushion. Although I could still bear it mentally, my body yawned like a conditioned reflex. .

"Did you stay up late last night?" The old man asked with concern as he sat aside and looked at Xu Chuan, who was yawning and feeling a little depressed.

Xu Chuan nodded and did not deny it: "I have done some research on some mathematical problems."

The old man said: "I will find you a guest room first. You can catch up on your sleep here for a while. The aerospace matter is not urgent. We can talk about it in the afternoon."

Hearing this, Xu Chuan said quickly: "It's okay, there's no need to bother. I'll just catch up on some sleep in the afternoon. Besides, I just woke up not long ago and I can't fall asleep."

The old man shook his head and did not try to persuade him any more. He smiled and said, "You should pay more attention to your health, stay up less late, and rest more. You are still young, and you still have a long time in the future. You can do your research slowly." Take your time."

Xu Chuan nodded and said with a smile: "I will pay attention."

The old man smiled, knowing that he probably didn't take this concern to heart.

However, this is what they arranged for the past life assistant and medical team to do. There was nothing they could do about staying up late, but they believed that their people would help him solve some of the physical risks caused by staying up late to the greatest extent.

After saying a few words of concern, the old man turned to the topic: "I would like to trouble you to come over this time. I mainly want to talk to you about some things about the development of the aerospace field, including the lunar biosphere that you wrote in your previous letter. Engineering and some work on the construction of lunar bases, etc.”

"You said it." Xu Chuan quickly replied.

The old man gathered his thoughts and spoke slowly: "Under your leadership, the manned spaceflight and lunar landing projects have achieved perfect success. The emergence of the Xinghai space shuttle has caused major changes in the future aerospace field. "

". Regarding the lunar biosphere project and the construction of the lunar scientific research base, there are currently differences of opinion among high-level officials, especially the former."

"Although this project is indeed worth investing in, it is related to our space strategy after all. Whether it is open to scholars from other countries, or the risks involved are difficult to assess. It just so happens that you are here today, and I want to ask you view."

Having said this, he looked at Xu Chuan solemnly and continued: "What do you think would be more appropriate if we want to cooperate in the future?"

Hearing the old man's inquiry, Xu Chuan smiled and said: "Regarding this project, I have read the previous research and discussion reports. The structure in the report is already quite complete, and there is no need for me to add anything. According to Once that comes, it’s already good.”

The ‘large lunar comprehensive base project’ will be separated into two parts, the ‘lunar biosphere project’ and the ‘lunar outpost scientific research station’. The former will be cooperated with the international community, while the latter will be completed by China alone.

There is no doubt that this is the most appropriate approach at present, and he can't think of any better solution.

Moreover, he himself is not a scholar in the field of engineering design. It is enough to leave this kind of engineering field to experts from the Academy of Sciences and the Academy of Engineering.

On the opposite side, the old man nodded and said, "The senior management's ideas are similar to yours. The lunar biosphere project can indeed be open to the whole world and involve scholars from all over the world and international scholars."

Xu Chuan said with a smile: "Actually, from a technical perspective, the lunar biosphere project is not very technical, but it costs a lot, and the results can be said to be relatively public."

“I suggest that the reason for opening up to the international community is, on the one hand, to take this opportunity to attract more international talents, such as scholars in astronomy, physics, biology and other fields to come to China to do research, or even settle down, immigrate, etc. "

"On the other hand, involving other countries and regions can save us more money and spend it in more valuable places."

Opening up the lunar biosphere project to the whole world was something he had thought about the pros and cons a long time ago.

Although some spies or intelligence personnel from other countries will inevitably be involved in this process, the biosphere project itself is a project with few secrets.

As for the controllable nuclear fusion reactor that provides energy for the biosphere project, it must be placed in its own lunar scientific research base, and there is no need to worry about too many leaks.

In addition, although biosphere engineering itself does not have many top technologies, China itself has no history of researching and developing biosphere engineering, and there are not even many scholars in this field.

On the contrary, although the United States' Biosphere 2 ultimately failed, it also cultivated a number of corresponding outstanding scholars and experts around the world.

Including biosphere temperature control, humidity control, sealing, ecological recycling and other fields of technology, these are actually quite excellent.

The United States’ aerospace technology is powerful, and it actually has something to do with Biosphere 2.

For example, the Artemis plan to launch the life support unit this time contains many technologies that have been further optimized from Biosphere 2.

With the help of this lunar biosphere project, it is actually a very good choice to attract these experts and scholars and obtain part of the ecological recycling technology.

On the whole, the advantages of involving international scholars and countries around the world in the lunar biosphere project outweigh the disadvantages.

Opposite him, the old man nodded slightly, acknowledging Xu Chuan's statement.

Talent attraction has always been a relatively weak link in China. Compared with attracting scholars from other countries, their own brain drain is more serious.

It is quite worthwhile to take this opportunity to change some of the international stereotypes about them.

Of course, for the country as a whole, what is more important is the expansion of international influence brought by the open lunar biosphere project.

There is no doubt that aerospace is the future development trend. Being able to gain a foothold in this field in advance and maintaining a leading position is undoubtedly their strategic deployment policy.

After chatting with the old man about the aerospace field for a while, Xu Chuan sorted out the thoughts in his mind and spoke again.

"Based on the perfect realization of the manned moon landing project, we have now seen the huge potential of the Xinghai space shuttle, which can replace traditional chemical fuel rockets to carry out various space activities."

"I think we now have the ability and need to set our sights on more distant deep space."

"That is: start the manned landing project!"

When I came here today, although I talked more about the development of the moon, for Xu Chuan, the purpose of his coming here this time was not the moon.

He does care about things on the moon, but to be honest, since the manned moon landing was completed and Chinese astronauts left their footprints on that land, his expectations for the moon have been lowered by several levels.

Coupled with the discovery of lunar ice and metal mineral deposits on the lunar surface, he further deepened his understanding of the moon and unveiled its mysterious veil.

At present, unless he can go to the moon in person, his interest in the moon will only be a little bit.

As for the construction of biosphere projects and lunar scientific research bases, although they are difficult, they do not require his own hands to accomplish them.

In contrast, his eyes had fallen on the more distant brown-red planet.

Listening to Xu Chuan's plan, the old man looked slightly moved.

He couldn't help but recall that when the controllable nuclear fusion technology was realized two years ago, the young man had talked to him here. Even in his opinion, it was so grand that it could be said that throughout the history of mankind, it was the only one that could be found. Less than planned.

Whether it was him at the time or other elders who knew about the plan, or academicians of the Academy of Sciences, experts, etc., almost everyone thought that it was an impossible goal.

This will not be possible for at least fifty years, or even within the twenty-first century.

But with the development of the past two years, he was now surprised to find that the project planned by the young man in front of him seemed to be being realized bit by bit.

From miniaturized controllable nuclear fusion reactors, to aerospace engines; to the Xinghai space shuttle, to manned spaceflight, and manned moon landings.

The development of the entire aerospace field is developing by leaps and bounds at a speed that is almost unimaginable to ordinary people.

Just like the breakthrough of controllable nuclear fusion technology, it has amazingly achieved one stage after another, solved one problem after another, and finally completed fusion ignition, opening a new era.
