It's normal to develop some black technology in the future, right?

Chapter 416 It takes a great country to complete him

Compared with Jack Ma, Chen Yuanguang is undoubtedly much more important. If Chen Yuanguang were to live in seclusion like Jack Ma, it would be an unacceptable consequence for China.

Alibaba will still be able to operate even without Jack Ma. Even if Alibaba is gone, there are other technology companies to take its place. But if Chen Yuanguang is gone, there will be no second top talent of this level to take his place.

Therefore, whether it is the consultant status of the Natural Science Foundation or the tentative kicking out by Yanjing to let Chen Yuanguang take over China Aerospace, it is all a test to see if Chen Yuanguang has such intentions. If so, then it is good that you enter this sequence and provide you with enough opportunities.

Chen Yuanguang took over the former, but he was only in charge of the funds allocated by the National Natural Science Foundation. He did not express his desire to gain greater power. Even after making epic achievements in the field of artificial intelligence such as HBM, he did not think that the efficiency of the National Natural Science Foundation he led was much higher than other parts of the National Natural Science Foundation, and he did not hope to take over the entire Natural Science Foundation.

The latter did not accept the offer at all. He was willing to cooperate, but as for asking him to be in charge of China's aerospace industry, Chen Yuanguang refused very straightforwardly without even hesitation.

This kind of political indifference made Yan Jing feel satisfied but also a little disappointed.

Therefore, the support for light armor companies is extremely strong, and light armor companies can easily obtain policies that other companies cannot.

The most direct support is to provide land, not commercial land, but residential land. After Guangjia Aerospace's headquarters was established in Shenhai, Shenhai issued a special policy for enterprises to apply to build residential buildings in the name of the enterprise.

You know, in a place like Shenhai where every inch of land is valuable, it is almost impossible for companies to allocate housing to their employees, unless the old state-owned enterprises in Shenhai have their own land and use it to build houses.

Or they can participate in the affordable rental housing project. After the company participates, it can get the right to use some houses, but it is just the right to use them. These houses can only be rented to employees.

So there is no difference between having it or not.

Shenhai’s policy requirements are almost identical to those of Guangjia Aerospace. Enterprises that meet the following conditions can acquire land to build residential buildings and allocate them to employees.

Of course, this is also due to the historical context, because the White House has relaxed restrictions on Chinese science and engineering students, and instead encouraged high-tech companies to poach Chinese talent, and then unconditionally gave them green cards. This has caused China to worry that Guangjia Aerospace's annual salary may not be attractive enough to talent in Shenhai, a place like this.

Therefore, we have come up with an almost customized policy to acquire land and build houses in the name of enterprises.

Back at the explanation meeting, some people had this thought in their minds: "The Chinese are still too civilized. If it were America, there would be no need to explain so much to you. It's better for the God of Light to explain it himself."

The reason why Ruguanxue is recognized by many people is that they find that no matter what the Chinese do, they will face all kinds of groundless criticisms, while the good and bad things done by American and his friends are all debated by great scholars.

“Why do we need to detonate near the metal core of an asteroid? In fact, the most effective way would be to directly hit the center of mass of the asteroid with a missile.

From a theoretical perspective, this can produce a more uniform thrust effect on the asteroid as a whole, and the impact force generated by the explosion at the center of mass can more effectively change the overall momentum of the asteroid.

For a nearly spherical asteroid of the same material, the center of mass will be at its geometric center. If our nuclear bomb is detonated at this location, the impact force will act on the asteroid in a relatively symmetrical manner, causing the asteroid to change its orbit as if it were pushed from the center.

This method can also prevent the asteroid from rotating or flipping due to asymmetric forces. Once it starts to rotate or roll, the difficulty of predicting and controlling its subsequent orbit will increase by more than one level.

Moreover, detonating a nuclear bomb near the center of mass will result in a relatively high energy transfer efficiency, which can cause the asteroid to achieve a larger overall velocity change, which will also help change the direction of its orbit. "

After Chen Yuanguang finished speaking, he sighed: "It's a pity that the current technology is not yet able to accurately calculate the center of mass of an asteroid from such a distance.

Because the material of asteroids is not uniform, even if it is a metallic asteroid, it will be composed of various metals such as iron, nickel, copper, and rocks, soil, carbon and other components. That is to say, its geometric center of mass is not its true center of mass.

The calculation rule we choose in this regard is to find the location of its metal core, and then hit the edge position of the tangent direction of the metal core location."

"Next, let's take a look at the simulated strike animation. Considering that the launch was today, we won't know whether the first nuclear bomb hits until tomorrow afternoon. As for whether the subsequent targets are achieved, our official Weibo will synchronize the news in real time."

To put it simply, the whole event was just answering questions and giving explanations.

After everyone had almost left, Musk still had an unveiling session with Chen Yuanguang the next day, so he didn't stay long. The same went for other bigwigs, but the bigwig from Yanjing stayed a little longer and exchanged a few words.

"Yuan Guang, I am also an engineering major. I cannot compare with you in academic attainments, but after all, I have worked in the industry for many years and I have some understanding of technology.

We often have experts from the aerospace industry come to give us extra lessons, hoping that we can catch up with the cutting-edge technology trends. Didn’t you come to give us lessons? We welcome you to come again. You come to Yenching too seldom.

I would like to ask, can this technical explanation dispel their doubts? "

Chen Yuanguang shook his head: "It can't be done unless we make our calculation model public, and detail how the orbit and multi-celestial body gravity model are constructed.

Only when it becomes specific to this extent may they dispel their doubts.

But if these are announced, the difficulties that America needs to overcome in replicating our technology will become very small.

Now, they have to overcome, at least the multi-body gravity model is the biggest hurdle in front of them.

It includes the precise characterization of chaos theory, the need for more effective chaos identification methods, the need to improve the understanding of the structure and properties of existing chaos imprints, and the need for further expansion in the construction of bifurcation types and the conditions for their occurrence.

Only in this way can we accurately understand the behavioral changes in different parameter regions of multi-celestial systems and build more accurate models.

In addition, at the high-dimensional manifold level, we need to improve the existing high-dimensional numerical integration algorithms and optimize the numerical stability, computational efficiency and accuracy of the existing algorithms. Including in the special symmetry configurations of some multi-celestial systems, they need to explore as many special cases as possible and prepare decomposable configurations in advance. "

When it comes to this, Chen Yuanguang talks a lot about sex, but the boss has already waved his hand: “Okay, okay, Yuanguang, that’s enough, I really don’t understand it.

I roughly understand what you mean. Between keeping technology confidential and allaying external doubts, we will definitely prioritize the former.

The math problem you just mentioned?"

Chen Yuanguang said: "I divided these into natural science foundation projects and gave them to young scholars from universities across the country to work on. They don't even know that their research projects are actually part of our multi-celestial body research.

It involves subdivision problems in many fields such as nonlinear dynamics, high-dimensional space mathematics, probability theory, and computational mathematics."

Before Chen Yuanguang finished speaking, the boss felt a little regretful, because everyone here hadn't left yet, and it was almost impossible not to be heard.

The foreign guests from various countries have not yet left, and anyone with better hearing can hear them.

These days, the news that an American company stole China's room-temperature superconducting technology is still on the hot search list.

Chen Yuanguang said that the mathematical problems would be handed over to the National Natural Science Foundation to solve, and the National Natural Science Foundation would publish the results every year. Moreover, the confidentiality level of the National Natural Science Foundation is very low. If America really wants to get the relevant project completion report, it will not be difficult at all.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

The boss was already having a headache, thinking that Chen Yuanguang was good in every way. He answered whatever he was asked, and was very excited when talking about professional issues. He looked like a typical scholar. The only problem was that he had no sense of confidentiality at all. But he couldn't blame him, after all, he was the one who asked the questions.

"Yuan Guang, stop, I understand."

After he finished speaking, the boss motioned for the secretary next to him to come over, and after whispering a few words, they moved to another empty room to continue the conversation: "Can America solve these problems?"

Chen Yuanguang said: "Of course, these are not difficult to solve. It's just that the final model has different accuracy and usability. It's the same as every new energy vehicle manufacturer has intelligent driving technology, but each manufacturer's intelligent driving is different."

"It means that we are now one step ahead of America. So when will they be able to accomplish it?" asked the boss.

Chen Yuanguang said: "The multi-body model is one of the links. In addition to the multi-body model, we need to see whether they want to use our technical solutions.

Didn't I just say at the meeting that the approach we take is to impact the edge of the asteroid's metal core in the tangential direction, which involves measuring the asteroid's metal core?

The common spectral analysis can only analyze the composition of the surface of the asteroid. Radar detection can only determine whether there are metal components, but it may not be able to penetrate into the core area.

Including gravitational measurements and neutron and gamma-ray detection, all have more or less limitations.

The second challenge for America is how to measure the location of the asteroid's metal core and then find the point we want to impact in our plan.

In short, this entire systematic project will take them at least five years and at most ten years.

If we make the model open source to them, the only technology they need to overcome is the accuracy of missile guidance technology. Judging from the asteroid trajectory change operation carried out by NASA in 2022, this is not a big problem for America.

In 2022, the asteroid they changed was called Dimorphos, which has a diameter of only 160 meters and is 1100 million kilometers away from the earth.

During the entire process, the Falcon 9 first sent their impactor into the predetermined orbit, and the control was handed over to the impactor itself for the last few hours. It finally hit the asteroid Dimorphos accurately at a speed of 22,000 kilometers per hour.

Therefore, if we want to release the entire model, it will only take America two years at most to master the entire technology.

Of course, even if we announce it, most countries will not be able to replicate it. Firstly, the number of near-Earth asteroids is limited, and secondly, there are very few countries with the relevant technology.

If we look at the global picture, perhaps Russia and France will be able to catch up.

Just maybe, because there are so many categories involved, I’m not sure they can handle it.”

This made the boss think of something: “What exactly does the factory need in order to complete the Varyag?
The Planning Commission, the Military Industry Commission, nine defense industry ministries, 600 related specialties, and 8000 supporting manufacturers, in short, it takes a great country to complete it. "

"Well, I understand. I also have another question that I hope you can answer for me.

That is, there is no lunar base on the lunar surface now, so we can land a near-Earth asteroid anywhere we want, including the entire bright side of the moon.

But we are going to build a base on the moon this year. I think China Aerospace's plan is to work together with Guangjia Aerospace to build large-scale solar panels on the bright side of the moon to utilize solar energy.

So it is certain that the larger the area, the more solar energy can be utilized, and the more things we can do on the moon.

If we still use this method in the future, have we considered how to reduce the impact of asteroids landing on the moon on our lunar base?"
