Great Country Academician

The discussion at the Institute for Advanced Study at Princeton is just a microcosm of the mathematical community.

One of the seven millennium problems, P=NP? The secondary problem of the conjecture is even more attractive to the mathematical community, especially scholars in the fields of computer mathematics, graph theory, group structure, and combinatorial mathematics.

As time goes by, the relevant discussions have also become more heated in the academic community, and even expanded to the computer field, and the sales of "Exploring Mathematics" have further broken through new highs.

Many mathematicians are lamenting that there will be one less place to compete for the Fields Medal at the International Congress of Mathematicians two years later.

After all, for the mathematical community, female mathematicians have always been very few.

The Fields Medal has been awarded for so many years, from the 1930s to now, it has been almost a century, and there are only three female mathematicians who have won this honor.

The first is Professor Mariam Mirzakhani, who has passed away, and the second and third are Professors Amelia and Marina, who received the medal more than a year ago.

From 1936 to 2022, in a full 86 years, only three female Fields Medals have been awarded. It can be seen that their number is very rare, a hundred times rarer than wild giant pandas.

After these three female Fields Medal winners, the International Congress of Mathematicians to be held in Jinling three years later will welcome another new female Fields Medal winner.

The proof that the factorization of large positive integers has a polynomial algorithm, coupled with the further breakthrough in the problem of graph isomorphism, is absolutely worthy of this honor.

At the official launch of the first issue of "Exploration·Mathematics", Xu Chuan paid attention to the sales and academic evaluation.

It must be said that for the mathematical community, which has never had much to eat, the first issue of "Exploration·Mathematics" has indeed caused a lot of discussion.

At least its academic reputation has been opened up because of this.

Not to mention how many mathematicians will submit articles in a short period of time, but at least in the hearts of most mathematicians, it has left a deep impression and set the level of "Exploration·Mathematics".

The breakthrough of the secondary conjecture, one of the seven millennium problems, was used as the opening paper. As long as there were no outrageous operations in the follow-up, its grade and level would be initially fixed in the mathematical community.

Just as Xu Chuan was paying attention to these things, on the other side, a major news came from the aerospace field.

NASA, the United States, held a press conference again nearly a year and a half after the failure of the last Artemis lunar module to land on the moon.

Director Bill Nelson personally presided over the press conference and announced that NASA's latest manned spacecraft moon landing activity, code-named "Artemis 2", will be successfully completed.

The three astronauts who landed on the moon have successfully collected a large amount of lunar soil, lunar rocks and other materials on the surface of the moon, and have perfectly completed the work of returning to the moon for this manned lunar landing, and are about to return.

And at the press conference, they also connected with two astronauts on the moon and conducted a two-minute short live broadcast.

Director Nelson also said that they are ready for the next manned lunar landing, and will launch the third manned lunar landing project within one month after the return of the manned spacecraft of Artemis 2.

And the landing site of the third manned lunar landing project will be selected at the South Pole of the Moon where the Artemis lunar lander had an accident.

At the press conference, Bill Nelson, director of NASA, said that both NASA and the United States have never been afraid of the difficult development of the aerospace field, and have never given up the development of the aerospace field.

Stand up from where you fall. Aerospace is the spirit of the United States and the pride of the United States. Even if you encounter setbacks, it is only temporary.

At the same time, Director Nelson also announced at the press conference that the new generation of space shuttle "Perseverance" jointly developed by NASA and Sierra Nevada Corporation has officially passed the preliminary acceptance work and is undergoing unmanned test flights.

It is initially estimated that the Endurance space shuttle will be officially put into service in three months. At that time, the Artemis program will be restarted, and NASA will join forces with the European Space Agency, the Maple Leaf Space Agency and other institutions to explore Mars.

As soon as this news came out, it once again sparked heated discussions in the field of aerospace, and also set off fierce waves in the United States.

Since the last time the Artemis lunar module manned lunar landing had a major accident, resulting in the failure of the lunar landing, and the two astronauts were trapped on the distant moon and fell to the point where they needed their competitors to rescue them, the mood in the field of aerospace in the United States has been depressed and morale has fallen to the freezing point.

Even if NASA publicly stood up and said that they would not give up the field of aerospace and announced that they would restart the space shuttle project, it did not arouse much morale.

After all, the failure of the Artemis lunar module to return to the moon and land on the moon was a huge blow to the American people.

You must know that before this, they have always regarded themselves as the world's number one aerospace power.

After the space race between the Red and Blue sides in the last century, their strength in the field of aerospace has been deeply rooted in people's hearts, and no country can catch up with them.

It has even become the national culture of the United States. Countless science fiction movies in the field of space are based on this, which makes people talk about it with relish.

As a result, in the new century, they fell a big fall in the field of aerospace.

This setback was so big that the American people were extremely disappointed with NASA, and their confidence dropped to freezing point.

At that time, some people even organized a large-scale demonstration to protest against NASA's inaction despite receiving so much funding every year.

As a result, no one expected that more than a year later, NASA "secretly" carried out another manned moon landing, and it was successful.

This news immediately boosted the American people's morale in the aerospace field, and for a while the reputation of the 'space power' seemed to be completely restored.

At the same time, Xinghai Research Institute.

In the office, Xu Chuan, who was dealing with the work at hand, also received the news.

The news was brought over by Weng Yunzong, the director of the Aerospace Research Institute. After taking the newspaper from the other party and flipping through it, Xu Chuan was a little surprised and spoke with interest.

"I didn't expect that the United States has not given up on the aerospace field, but it's good to have a competitor. It's interesting."

Although this competitor has already been left behind by them.

Whether it is manned landing on the moon or the construction of a lunar outpost scientific research station base, their development in the aerospace field is no longer comparable to that of the United States.

But then again, this feeling of being alone and seeking defeat, singing a one-man show on the whole world's stage is indeed a bit too lonely.

Xu Chuan thought it was quite interesting that the United States could come back.

Weng Yunzong said with a smile: "Even if NASA and the United States do not give up, they will never be able to catch up with us again."

After a slight pause, he continued: "Speaking of which, I think this matter may have something to do with the lunar biosphere project."

Hearing this, Xu Chuan glanced at Weng Yunzong curiously and asked, "Lunar biosphere project?"

"Um."

Nodding, Weng Yunzong continued to explain with a smile: "The construction and specific quotas of the lunar biosphere project are almost finalized. According to the current progress, the project construction can be officially started around mid-March."

"But NASA and the United States have not repealed the Wolf Clause and the New Competition Act so far, so we are excluded this time and are not eligible to participate in the lunar biosphere project."

Hearing that it would take about a month and a half to officially launch the lunar biosphere project, Xu Chuan couldn't help but shook his head and complained: "This efficiency is simply too high."

Negotiations on the lunar biosphere project began in the second half of last year. Several months have passed, and the fight for interests and voice is still ongoing.

You know, when he originally proposed the lunar orbital mass projector, he was ready to start construction at the beginning of 2025.

Now the base of the lunar outpost scientific research station has been prepared. A large number of scientific researchers, engineers and construction equipment have been transported there. There are still ten days left for the formal construction of the lunar orbital mass projector.

The lunar biosphere project is still in development, and it is still unknown whether it will be finalized within a month.

This is the drawback of large-scale international collaborative scientific research projects.

All kinds of things need to be discussed in meetings. Fortunately, he didn't become the chief engineer of the lunar biosphere project.

Otherwise, having meetings all day long would bore him to death.

Weng Yunzong didn't pay much attention. He smiled and said: "In large-scale international cooperative scientific research projects, a project with an investment of more than 100 billion for more than one phase can be finalized in half a year. This progress is already very fast."

"Honestly, if we hadn't occupied an absolute dominant position in this project, I'm afraid we would still be wrangling over the distribution of benefits."

Xu Chuan smiled and shook his head, but didn't say anything.

Such large-scale international cooperative scientific research projects are slow to start, slow to negotiate, and slow to construct. In short, they are slow in all aspects.

The original International Thermonuclear Controlled Nuclear Fusion Project ITER was initiated in 1985. However, it took three years from its establishment to distribution of benefits and the start of construction. It was not until 1988 that the formal design, construction, etc. were completed.

After thirteen years of hard work, ITER was completed.

After the construction was completed, the controllable nuclear fusion experiment was supposed to be officially launched. When researching controllable nuclear fusion technology, the parties involved quarreled again over the distribution of experimental resources and benefits.

After another five years of negotiations, the seven ITER projects finally formally signed a joint implementation agreement in 2006 and launched the implementation of the ITER project.

If it hadn't been for such a delay, China at that time might not have had the chance to participate in this large-scale scientific research project.

After all, when they first entered the new century, they were still very poor. Not to mention scientific research and technology, they didn't even have much money.

From the ITER project, it is enough to see how slow this kind of large-scale international scientific research project is.

After chatting about aerospace work for a while, Weng Yunzong was about to leave when he suddenly remembered something, patted his head and said quickly.

"By the way, there is one more thing I almost forgot about, about the Aitken Basin in the South Pole of the Moon."

Xu Chuan looked over and asked subconsciously: "What happened to the Aitken Basin?"

Weng Yunzong smiled bitterly and said, "Have you forgotten? During the manned moon landing competition two years ago, NASA launched a life support unit above."

"Now they are returning to the Aitken Basin in Antarctica."

Hearing this, Xu Chuan was also stunned. The two looked at each other, a little embarrassed.

After a while, Xu Chuan asked, "Is that thing still there?"

Weng Yunzong smiled embarrassedly and said, "It's still there, but..."

"It's fine, but what?"

Weng Yunzong said weakly, "But that thing has been dismantled by us and now it's a pile of parts lying in the Yuehuatai Outpost Research Station."

Xu Chuan: "."

Sighing, he said, "I asked you to study it, but you studied it too thoroughly, right? You just dismantled it into parts?"

Of course, after NASA failed in the competition for manned lunar landing, they arranged for the Xinghai to rescue. While rescuing the other astronauts, they naturally recorded the location of the other party's lunar module and life support unit.

In the spirit of helping others, in order to prevent the thing from being damaged by wind and sun on the surface of the moon, they dragged the life support unit to the base of the Yuehuatai Outpost Research Station and kept it for the United States.

I didn't expect that the people over there would actually dismantle the things "without authorization"

Weng Yunzong scratched his head, smiled shyly, and said: "Isn't this thinking of studying it more thoroughly?"

"If we hadn't learned a lot of technology from it, the construction of our lunar outpost scientific research station wouldn't have been so smooth, right?"

It has to be said that the Americans have been developing in the field of aerospace for decades and have been the largest aerospace country for decades. There are still many good things.

From that life support unit, they did develop a lot of technology, such as circulatory system, life support system, communication system, etc.

These technologies were later used by them in the construction of Yuehuatai Outpost Scientific Research Station Base, and the effect was quite good.

Xu Chuan breathed a sigh of relief and shook his head and said: "Can it be assembled?"

Weng Yunzong quickly replied: "Yes, when it was dismantled, the disassembly process was fully recorded."

NASA probably didn't think that this thing would fall into the hands of others. Although there was a locking system, there was no self-destruct module, so they could easily dismantle the thing.

Xu Chuan waved his hand and said, "Assemble it and put it back to where it was, so they won't find fault with it."

He didn't care too much about it, as long as the things were still there.

It didn't matter if it became parts, just assemble it and send it back.

As long as the other party didn't know that they dismantled the life support unit.

It's research, this kind of thing is done by everyone behind each other's back, it's no big deal.
