Great Country Academician

After chatting with the president of the largest Internet company in the country for a while and initially finalizing some cooperation in the fields of artificial intelligence and aerospace, Xu Chuan sent the legendary Ma Ge away.

For Penguin Group, most people in China have the impression of two major parts: communication + games.

If you are a gamer, you may need to add copycat master + krypton gold to become stronger. Playing Tencent's games is either recharging money or on the way to recharging money.

Coupled with "micro" innovation and complaints from strange parents, this company, which is actually very low-key in the industry, is always at the forefront.

However, compared to another Malaysian president, this pony president is indeed much more low-key, and even the company Penguin is also relatively low-key.

On the one hand, it has to do with this person's character, and on the other hand, it may be that he has been educated by Ta before.

But aside from these things, Penguin Group does have what Xu Chuan needs.

At least in the area of ​​artificial intelligence, the huge Internet data + a large number of programmers will be of great help to what he will do next.

In China, there is probably no other company that is more suitable than Penguin.

The day after the bidding conference, Xu Chuan contacted representatives of the Aerospace Science and Industry Corporation and found the R\u0026D personnel who demonstrated the 'satellite grabbing' technology at the conference.

The person who developed this technology was a middle-aged professor named Ji Shi.

In the coffee shop downstairs of the hotel, Xu Chuan saw him in person, smiled, shook hands warmly and said hello: "Hello, Professor Ji."

With a smile on his face, Ji Shi took Xu Chuan's hand and shook it enthusiastically: "I have heard about Academician Xu for a long time, and today I finally have the opportunity to meet him. He is as young and promising as the rumors say."

Xu Chuan smiled and said: "Professor Ji is overly praised. Please sit down first and let's sit and chat. I hope that inviting you over this time will not disturb your schedule."

"No, no, what are you talking about, Academician Xu?" Ji Shi sat down with a smile on his face, his butt touching half of the chair.

For him, the academician-level boss was already a ceiling-level figure, let alone the top academic figure in the country in front of him.

The name Xu Chuan has long been familiar to him. He even peeked at it several times during the bidding meeting yesterday. He didn't expect to receive an invitation from this person today.

Xu Chuan smiled and said, "What would you like to drink?"

Ji Shi: "Just a glass of boiled water."

Xu Chuan smiled and said, "You don't have to be so polite. I can still afford a cup of coffee."

Ji Shi said with some embarrassment: "Um, Academician Xu, I'm allergic to coffee and I can't drink coffee."

The corner of Xu Chuan's mouth twitched. He didn't expect this. He said awkwardly: "Ahem, I'm sorry, I didn't expect this."

"It's okay, just give me a glass of boiled water. I always drink bottled water at the institute." Ji Shi shook his head quickly and said with a smile.

"Okay, waiter, could you please give me a glass of water and a cup of green tea?"

Xu Chuan shouted and asked the waiter to prepare. Then he looked at Ji Shi, who was sitting opposite him, and continued with a smile: "I take the liberty of interrupting Professor Ji, mainly because I have something to ask."

Ji Shi nodded quickly like a chicken pecking rice: "Academician Xu, please ask."

"It's like this. Yesterday at the bidding meeting, I saw the 'satellite capture' technology you reported on stage. I am somewhat interested in this. Could you please Professor Ji and talk to me about this?"

Ji Shi nodded and said, "Of course it's no problem."

After pondering for a while and organizing his words, he continued: "About satellite capture technology, it refers to the satellite moving to the space orbit of the target satellite under ground-assisted guidance and autonomous guidance, and then slowly approaching the target spacecraft. technology to dock or drag the target within a given capture tolerance.”

"Including the assembly and docking of the space station and the transportation of materials in aerospace engineering, some of them are also related to this technology."

"Compared to foreign countries, domestic rendezvous and docking technology has just started. The environmental specificity, complexity and high cost of space rendezvous and docking technology have resulted in relatively few research results."

"However, the importance of this technology is still quite high. Whether it is used to clean up the increasing amount of space junk, retire satellites, orbit refueling, assemble the International Space Station, space offensive and defensive confrontation, etc., it needs to be used. technology."

Ji Shi briefly introduced the core and future of satellite capture technology. Xu Chuan nodded after listening and asked: "What is the cost of this technology? Can it be used on meteorites or asteroids?" "

Hearing this question, Ji Shi thought for a while and replied cautiously: "The cost of satellite capture technology is not very high. Generally speaking, another spacecraft is captured in orbit through a robotic arm."

"If it is used to capture meteorites or asteroids, I'm afraid it will be more difficult."

"Because compared to equipment such as spacecraft and satellites, the speed of meteorites and asteroids is much faster overall."

"If it is those meteorites and asteroids heading toward the Earth at high speed, their speeds can even reach tens of thousands of kilometers per hour, and can reach exaggerated speeds of hundreds of kilometers per second."

"If you want to capture this type of celestial body, you need the capturer to have the ability to resist the kinetic energy generated by this speed. In fact, the current satellite capture technology, whether in terms of kinetic energy, robotic arms, materials, etc. Don’t have such ability.”

"Even the most advanced FREND robotic arm in the United States can only be applied to most non-cooperative target satellites in space. It is also powerless against high-speed flying asteroids."

Ji Shi shook his head and explained softly.

He thought that the young national treasure-level scholar in front of him wanted to develop technology for intercepting meteorites and asteroids.

But honestly, it's just too difficult.

Instead of using satellite capture technology to change the trajectories of meteorites and asteroids rushing towards the earth, it is better to directly use missiles or nuclear bombs to smash and burn them in the atmosphere, or change their trajectories/turn them into small pieces, etc., which will reduce the impact on the earth. The damage and impact power are more realistic.

Xu Chuan thought for a moment and said, "What if it's for meteorites or asteroids orbiting in fixed orbits in the asteroid belt between Mars and Jupiter?"

After a slight pause, he continued: "In other words, if I want to pull out meteorites or asteroids from the asteroid belt and move them to other locations, can this satellite capture technology be used?"

Hearing this question, Ji Shi glanced at Xu Chuan in surprise, not quite understanding what this person meant or what he wanted to do.

But literally speaking, there is an answer to this question.

After thinking for a while, he said: "This depends on the size and speed of the meteorite or asteroid. If you want to change the trajectory of an object running in space, or stop it completely, you must have corresponding work."

"While in theory this can be done, it would be a huge strain on the robotic arms commonly used in satellite acquisition technology."

After a pause, Ji Shi made a joke and said: "Instead of doing this, it is better to follow the method in Wandering Earth and install planetary engines on the surface of the planet to change the trajectory of the earth."

"At least compared to the Earth, the size and mass of meteorites and asteroids in the asteroid belt between Mars and Jupiter are countless times smaller. It is nothing to slowly change their orbits through the Hall propulsion unit. impossible things."

Hearing this, Xu Chuan's eyes suddenly lit up.

Yes, why bother using satellite grabbing technology to change the trajectory of an asteroid? Isn't it enough to think of meteorites and asteroids as a spacecraft, using small engines to change its direction and movement?

This method is really good and theoretically feasible!

After thinking for a while, he looked at Ji Shi with bright eyes and said with a friendly smile: "Professor Ji, are you interested in working at Xinghai Research Institute?"

"In terms of salary, I can guarantee that it will be at least twice what you get at Aerospace Science and Industry. What about benefits and benefits? I think you should have heard of the reputation of Xinghai Research Institute. It will definitely not be bad."

"ah?"

Hearing Xu Chuan's invitation, Ji Shi was stunned for a moment, with a confused look on his face.

What's going on? Why did he suddenly fast forward to invite him to Xinghai Research Institute?

Opposite me, Xu Chuan smiled and said, "How about it, Professor Ji? Although the reputation and history of Xinghai Research Institute are not as long as those of aerospace technology, working there is still quite good."

"I can guarantee that after you come here, in addition to doubling your salary, you will also be able to have your own independent laboratory, and you can also lead a team to continue the research and development of satellite acquisition technology."

After hearing Xu Chuan's words, Ji Shi finally came to his senses.

It has to be said that the conditions offered by Xu Chuan are quite tempting to him.

He has naturally heard of Xinghai Research Institute's status in the domestic academic world. Although this scientific research institution was not established very long ago, it is modeled after the Institute for Advanced Study in Princeton in the United States. It is definitely unique among domestic academic circles. of.

As for the evaluation and evaluation of scientific researchers within Xinghai Research Institute, it is completely different from the domestic academic community.

In addition, Xinghai Research Institute's salary, benefits and other benefits can be said to be top-notch in the country, and even in the world, it is considered very good.

The salary is doubled, the project remains the same, and I have my own independent laboratory.

I have to say that this condition is really tempting to him.

The only thing that made him consider was whether Aerospace Science and Industry would agree to his resignation, and the troubles that would arise from moving from Beijing to work in Jinling.

After thinking for a while, Ji Shi looked up at Xu Chuan and said emotionally: "If it is this condition, I would be very willing to work at Xinghai Research Institute, but regarding work transfer, it may be a bit troublesome for me. , it may take some time.”

Only after hearing this question did Xu Chuan react.

Aerospace Science and Industry is not only a state-owned enterprise, but also falls under the jurisdiction of the military. Its nature is quite special.

Employees like them, especially scientific researchers, have signed confidentiality agreements and the like when they join the company. If they want to leave, they can, but there are big considerations in the subsequent work and difficulty.

Smiling, Xu Chuan said, "There's no problem with this. I'll just ask the Xinghai Research Institute to say hello to the Aerospace Science and Industry when I get back here."

If he wants to be an individual, he is not a person with core technologies such as launch vehicles, aerospace missiles, etc. There won’t be any big problem, and the Aerospace Science and Industry Corporation will still give him the respect.

Hearing this, Ji Shi swallowed his saliva and said, "Then let me prepare when I get back here?"

Xu Chuan nodded and said with a smile: "Okay, you can just report directly to Xinghai Research Institute when the time comes. I will say hello to the personnel department."

Ji Shi took a deep breath and said excitedly: "I'm sorry to trouble you, Academician Xu."

Although this was just an unexpected gain after poaching a talent from the Aerospace Science and Industry Corporation, Xu Chuan was still in a good mood, so much so that Beihang University invited him to give a report, and he agreed.

This straightforward answer made the leader of Beihang University who invited him stunned for a moment. Then he jumped three feet high in excitement. After hanging up the phone, he quickly ran to inform others.

The next day, in the auditorium of Beihang University, standing on the stage, Xu Chuan used a clear and steady voice to give a lecture on the unified framework theory of "condensed matter physics" and "strongly correlated electronic systems" to the students of Beihang University. 'Report.

".Substances exhibit symmetry breaking in certain states, where the symmetries of the relevant physical laws are broken. A common example is crystalline matter, which has complete translational and rotational symmetry It’s all destroyed.”

"For example, in crystalline solids, these Goldstone bosons are called phonons - quantized forms of lattice vibrations. Others include magnons, quasi-electrons, excitons, polaritons, etc., which are present in Excitation at arbitrarily low energy is Landau’s elemental excitation.”

"Symmetry breaking is a ubiquitous phenomenon in condensed matter physics. Through the 'Grand Unified Framework Theory of Strongly Correlated Electronic Systems', we can understand changes such as symmetry breaking, high-temperature superconductivity, giant magnetoresistance, metal-insulator transition, etc." The basis of."

“Now I will focus on some applications of the ‘Grand Unified Framework Theory of Strongly Correlated Electronic Systems’”

The stage was dark and crowded. Not only were there no empty seats, there were even people sitting in the corridors.

After hearing this report on 'Condensed Matter Physics' and 'Grand Unified Framework Theory of Strongly Correlated Electronic Systems', not only students from Beihang University, but also students from Shuimu University and Peking University, and even some nearby materials research institutes The researchers all came running over.

The auditorium can accommodate thousands of people, but nearly 10,000 people might be squeezed into it.

For researchers from Beihang University, other universities such as Shuimu and Peking University, and even researchers from the nearby Institute of Materials, Xu Chuan personally explained the application of the "Grand Unified Framework Theory of Strongly Correlated Electronic Systems", which can be described as a feast.

Leaving aside those people from other departments who were just watching the excitement, most of the students sitting in the auditorium were listening very seriously, and their notebooks were already filled with various key notes.

For Xu Chuan, spreading his ideas, theories and results to other students and researchers is also something he is happy to do.

After all, the development of a discipline, the development of a country, and the development of a civilization is far from enough for him alone.

The core of condensed matter physics, the ‘Grand Unified Framework Theory of Strongly Correlated Electronic Systems’, is of great significance to the development of materials physics.

Especially for students from Beihang University, they have a large number of students and professors working in the aerospace field. For aerospace technology, the material itself is undoubtedly the top priority.

This report does not necessarily bring much results to Beihang University and other students, but it will at least enable these students, researchers, and even professors to walk on the path of condensed matter physics and materials physics more easily and more efficiently. farther away.

For these audience scholars, the only response to this lecture was the warmest applause.

Therefore, when the last words on the podium fell, the entire auditorium was instantly filled with waves of applause that lasted for a long time.
