"Wouldn't it be a little too anxious to carry people on fire?"

In the hall, the old man listened to Xu Chuan's suggestion, thought for a while and asked.

Now that the manned lunar landing project has only been completed, and the 'large-scale lunar comprehensive base project' has just been confirmed, there are still many things on the moon that are worth exploring and developing.

And the difficulty of manned landing on the moon and manned landing on fire is not the same concept.

The former is a satellite of the earth, and its orbit and distance can be said to be relatively fixed, and the maximum distance between the earth and the moon is only 400,000 kilometers.

But even the shortest distance between Earth and Mars is as high as 55 million kilometers; And if it is the farthest distance, it is more than 400 million kilometers.

Moreover, compared to the moon landing, they have little experience in the fire so far.

With the exception of Tianwen-1 and Zhurong, which were only successfully launched in 2021, their understanding of Mars is far less comprehensive than that of the Moon.

If the difficulty of a manned landing on the moon is 10, then the difficulty of manned landing on fire is at least 100, or even higher.

After all, with today's space technology, a trip to Mars would take at least a few months.

How to ensure the safety of astronauts in space for several months, as well as the work after landing on Mars, is a huge problem.

Hearing the old man's concerns, Xu Chuan smiled and said, "It's not early, and it's not in a hurry." ”

After a slight pause, he continued: "There is no doubt that the moon is the focus of our development at the moment. ”

"It is our bridgehead to the universe, and its special environment of low gravity and no air is extremely suitable for use as a transit and supply station, and its strategic position is naturally needless to say."

"But on the whole, because of the unique environment of the moon, it is not suitable for large-scale migration. The human body is currently not adapted to living in a low-gravity environment for a long time, and a variety of physical problems and diseases may arise in the future. ”

"Therefore, it is inevitable to look further into deep space."

"In the solar system, most of the planets or moons are too different from the earth in terms of basic conditions, and only Mars is close to the parameters and has the conditions for large-scale colonization."

"Therefore, in the future, whoever can occupy Mars first will undoubtedly have greater potential for the universe."

"As for the manned landing plan, it does not conflict with the development of the lunar surface. Relatively speaking, the manned fire-landing project does not cost a lot of money, and the main purpose of this project is to examine the environment of Mars and see if it has the potential to be transformed into a second home. ”

Xu Chuan has never forgotten his Mars transformation plan, and judging from the Martian data and related information obtained in the past, the potential of Mars is undoubtedly quite large.

It has a young, incompletely cooled core, and even recent probes have observed traces of eruptions on Mars in the last century or so.

This means that it is not impossible to restore the magnetic field to the solar wind and cosmic radiation, although it is very difficult.

Listening to Xu Chuan's words, the old man's face was slightly moved, and after thinking about it, he spoke: "This is prepared for the plan you mentioned before?" ”

He naturally understands the difference between Mars and the Moon, but what makes him more concerned is the grand dream that the young man in front of him has described here after the controllable nuclear fusion engineering technology.

Xu Chuan nodded and said with a smile: "On the one hand." ”

"The development of Mars is indeed more valuable than the Moon, which is in every sense the most habitable planet in the solar system other than Earth."

"Even if there is no renovation plan I mentioned earlier, building a colonization base or even a colonization city on Mars is something to consider."

After a pause, he continued: "Maybe many people will think that it is still early, after all, our aerospace is just getting started, and there is no need to rush to promote these work." ”

"But in my opinion, aerospace is a kind of work that should be done sooner rather than later. If it drags on, no one knows what the future will look like, so it is better to further expand this advantage while we have already occupied a certain advantage in the aerospace field. ”

Hearing this, the old man nodded lightly and agreed with Xu Chuan's statement.

As a country that has experienced the slumber of modern history, after the industrial revolution, they are basically in a backward position in many fields, especially in the modern high-tech field.

And in the past few decades, only they know how many losses, how many hardships, how many blood and tears they have shed.

Now that I finally have some leading areas, there is no reason not to continue to expand my advantages in these areas.

After chatting with the old man about the development and future deployment of aerospace and other fields, and after politely rejecting the old man's request to invite him to have a light meal at home, Xu Chuan left the small island in Beihai and returned to the Beihai Hotel.

"Zheng Hai, help me book a high-speed rail ticket back to Jinling this afternoon."

In the hotel, Xu Chuan explained to Zheng Hai while packing up his things.

"Aren't you going to Mizuki University tomorrow?" Hearing the order to buy a ticket, Zheng Hai subconsciously asked.

Xu Chuan's itinerary was arranged by him, after all, to his extent, although it is impossible to restrict activities, travel safety is not a trivial matter, and basically normal travel is arranged and handled in advance.

For example, this time in Beijing, he and the security team prepared a week in advance.

Not only did I understand the travel arrangements with Xu Chuan, but also some places that I often visited, such as Mizuki University, where Xu Xiao is located, and the Academy of Sciences, all of which were investigated and prepared in advance.

Including the high-speed rail, his travel now is basically directly wrapped in the business class of the high-speed train, that is, there is no one else in the entire carriage except for him and the members of the security team.

Xu Chuan packed his luggage and replied casually: "Let's go next time, I'll go back to Jinling first." ”

Nodding, Zheng Hai didn't ask any more and asked, "What time do you need?" Or is it the sooner the better? ”

"The sooner the better."

"Okay."

In response, Zheng Hai walked out quickly.

If you want the fastest speed, then go directly to the person on the other side of the railway gate.

Although the tickets for this afternoon have probably been sold, it is not difficult for them to clear a carriage.

Although they don't look very obvious as security guards in normal times, their level is quite high. Not to mention the railroad gates, if they need it, they can directly draw people from the local police station or even the army.

Zheng Hai was very reliable, and it didn't take long for Xu Chuan to catch the high-speed train from Beijing to Jinling.

In the business class, the idea of taking a nap on the road was finally canceled by him.

He is not sleepy now, and he is more willing to use the hours on the high-speed train to organize his thoughts last night than to catch up on sleep.

Although it is certain that it will not be done, even if it is just the improvement of the tool to solve the Riemann conjecture, it will not be done in a day or two, but it is possible to continue to extend it.

A few hours of travel is not a long time, and under Zheng Hai's reminder, Xu Chuan sorted out the manuscript paper on the small table and frowned.

The thick manuscript paper was already full of calculations, and there were a lot of waste paper balls piled up in the garbage basket next to it.

But the improvement of the tools on his hand was not as smooth as he imagined, especially in the reference of multiple complex variable functions, he always felt that something was strange.

It's not that he didn't sort out his thoughts, but he felt that the road he had sorted out seemed to have some abyss in front of him that he hadn't yet understood.

Shaking his head, Xu Chuan stuffed the manuscript paper on the table into his backpack, although he was a little entangled, but for now, this idea can continue to go down, and he will talk about it when it doesn't work.

The Riemann conjecture is a top-level mathematical problem that is incredible, if you don't encounter a problem in the process of solving it.

It was already evening when the high-speed rail stopped, Xu Chuan didn't go home, and rushed directly from Jinling South Station to Chuanhai Network Technology Co., Ltd.

The sunset in early autumn rendered the headquarters building of Chuanhai Network Technology Company a golden patch, and by taking the elevator, he found the senior sister who was still busy with her work in the office.

knocked on the door, in the office, Liu Jiaxin, who was studying something, was awakened by the knock on the door, and when she looked up and saw him, she was obviously stunned for a moment, and then a smile floated on her face.

"Why are you here, aren't you still in the capital in the morning?"

Xu Chuan smiled: "I just came back." ”

Liu Jiaxin got up, walked to the table and poured a glass of water and asked, "I didn't delay your business, did you?" ”

Xu Chuan shook his head and said, "No, I originally planned to come back tomorrow, just a little earlier." ”

As he spoke, he pulled out a stack of manuscript paper from the backpack he was carrying. It's some of the stuff he sorted out on the high-speed rail last night and this afternoon.

"I've read your paper, and on the whole I haven't found any flaws or problems for the time being, and in my intuition, you've done it for the polynomial factorization of large integer factors."

Handing over the manuscript paper in his hand, Xu Chuan continued: "However, there are some places, I still have some doubts, and some things that should be optimized, I have sorted them out." ”

"It's just that the time is relatively tight, and I haven't done much here, you can take a look first, and I'll improve it later."

For the world's top problem of polynomial decomposition of large positive integer factors, even he could not figure out all the details in a day.

After all, that's not his area of expertise.

Liu Jiaxin nodded, took the manuscript paper from his hand, and flipped through it carefully, with bright brilliance and a thoughtful look in his eyes.

Anything else, the advice of a top math guru is absolutely indescribable in words.

Although Xu Chuan said that it was only done in a hurry, she still saw a lot of areas from it that she had not considered herself.

For example, when quoting and judging Hilbert's zero-point theorem, strong formal representations need to define algebraic sets, which is the most common application.

But on the manuscript in her hand, he made a self-defeating L-function with the elliptic curve Haas-Weil function, and then used this self-defense function to correspond to the GLn functions in the algebraic number field, and these self-defending L-functions can be uniquely decomposed into the product of the "standard" L-function.

There was no doubt that these things had not been considered by her before, and it was enough to see the vastness of the knowledge of the person in front of her in the field of mathematics.

After quickly flipping through the things on the manuscript paper in her hand, Liu Jiaxin raised her head and looked at Xu Chuan, with a streamer in her eyes, pursed her lips, and said, "I may need some time to deal with these things." ”

Even though it was just something that Xu Chuan had sorted out, she needed more time to understand and process.

Xu Chuan didn't care, waved his hand and said, "It's okay, you can keep these things." It was meant for you. ”

"Also."

After a pause, he handed over another manuscript paper in his hand, and continued, "Look at this. ”

These are some other things he sorted out, and he always feels that there are some inexplicable problems in this idea in his hand, but for a while, he can't find out where the problem is.

Show her, maybe it can help.

After all, this idea was extended from her solution to the polynomial decomposition problem of the big positive integer factor.

With a look of some doubt, Liu Jiaxin took the manuscript paper, and the equations and formulas on the A4 paper attracted her.

"It's."

From the manuscript paper in her hand, she saw a lot of familiar things, which were the same methods she had used in her previous studies of the polynomial decomposition puzzle of the big positive integer factor.

But more often than not, it is the twisting, deformation, and integration of the methods she uses with other mathematical tools.

Xu Chuan took the water cup, took a sip of water and moistened his throat and said, "A little bit of an extension of the method you used in your previous research, I think it may help us make a breakthrough in the Riemann conjecture?" ”

"Riemann conjecture?" Liu Jiaxin was stunned for a moment and looked over.

Xu Chuan nodded and said, "Well, I just feel that I don't know if it will work yet, and this tool has not been finished yet, and there is only a general idea at present, what do you think?" ”

Liu Jiaxin glanced at the manuscript paper in his hand, then looked at Xu Chuan, shook his head gently, and said, "I have not studied the Riemann conjecture. Still."

After a slight pause, she flipped through the manuscript paper in her hand, and continued: "However, regarding the polynomial function reference on the yoke matrix, the idea you wrote is different from the idea of the multi-complex variable function theory I quoted. ”

"I don't quite understand your application and understanding of this, can you tell me about it?"

Hearing this, Xu Chuan put down the water glass in his hand, leaned over, and saw the place she was pointing at.

"Here is the symmetry group S2n and the superoctahedral group {±1}n· The spherical function of Sn gives the algebraic definition of Z."

Looking at the place pointed out by Liu Jiaxin, Xu Chuan opened his mouth to explain.

Listening to Xu Chuan's explanation, Liu Jiaxin frowned slightly and said: "But if this is the case, its inner product will be determined by =mαδmn, so that for the special case of α=1, the expansion coefficient will be undetermined." ”

Although she doesn't know much about Riemann functions, she is still very clear about the tools she has used.

In her opinion, there are some problems with this reference to multiple complex functions.

Listening to Liu Jiaxin's words, Xu Chuan was stunned for a moment.

He stared blankly at the manuscript paper in front of him, and the whole person was stunned.

No wonder, no wonder he always felt that something was wrong when he was calculating these things last night and this afternoon.

A word to wake up the dreamer!

α the expansion of the coefficient, he actually ignored this key point.
