On the other side, Huaguo, Jinling.

After dealing with the paper on the Yang-Mills equation, Xu Chuan did not pay attention to this.

Bryan Howard's situation, he also did not know, and he did not have the heart to pay attention to him.

There are still more than 20 days before the report meeting, and this time is enough for him to do something else.

For now, what worries him the most is not the development of miniaturized controllable nuclear fusion technology and aerospace engines.

After he has mastered the improved superconductor material, the early research will not encounter too many problems in theory.

As for the various problems that may be encountered in the middle and later stages, it will take longer time and experiments to test them.

At the moment, what worries him the most is the construction of the large strong particle collider.

After CERN suspended its cooperation with Huaguo, the relevant technical personnel have basically been evacuated, and it is impossible to send the technology related to the detectors that were originally stored in CERN.

And with Huaguo's own collider technology reserves, it is basically impossible to keep up with CERN.

After all, CERN has gathered funding from most of the world's countries capable of studying the field of high-energy physics over the years, and most of the world's high-energy physicists have done research there.

Fortunately, Xu Chuan was able to ease this concern a little by the fact that a few years ago, Hua Guo joined CERN and became a member of CERN, and obtained a lot of open technology from CERN.

And that includes a lot of stuff about the construction of the collider and the particle detectors.

Although none of these technologies are the latest reserve technologies, some directions for CERN's development can be gleaned from these technical materials.

On this basis, the optimization of the large strong particle collider and the design of the detector are undoubtedly the most important tasks he needs to carry out at present.

In the office, Xu Chuan turned on the computer and printed out the information transmitted by the Huaguo Physical Society.

Tang Ran took out the materials from the printing room and delivered them to him.

"Professor, your information."

Xu Chuan took it and nodded with a smile: "Thank you." ”

Glancing at the information in Xu Chuan's hand, Tang Ran opened his mouth and stopped talking.

Xu Chuan, who happened to see this scene, casually asked, "What's wrong?" What's the matter? ”

It may have been with Xu Chuan for a while, and Tang Ran's work in the office was not as restrained as at the beginning, she thought for a while and asked curiously: "It's nothing, but I'm a little curious."

Xu Chuan: "Huh? Curious about what? ”

"Aren't all of these documents available in electronic versions, but you seem to print them out every time, Professor?" Looking at the paper materials in Xu Chuan's hand, Tang Ran asked curiously.

Hearing this question, Xu Chuan raised the information in his hand with a smile and said, "For personal reasons, I prefer paper documents." ”

After a slight pause, he added: "Because this can make me feel the weight of knowledge clearly." ”

Tang Ran nodded as if he didn't understand, and turned to leave.

As a person who is accustomed to mobile phones, computers, and tablets, it may be difficult for her to understand the feeling of holding original books and materials.

Xu Chuan smiled and didn't care about this.

I sorted out the information in my hand and flipped through it.

There are three main types of colliders at the European Atomic Energy Research Agency.

The first section is the most spectacular particle acceleration ring, which is 27 kilometers long.

This part of the structure is housed in a near-perfect circular tunnel with two vacuum pipes placed in parallel.

The reason why there are two is because the proton beam is accelerated separately in the two pipes, one in clockwise motion and the other in counterclockwise motion in order to achieve the effect of a head-on collision.

The second part is a superconducting magnet wrapped around the acceleration pipe and a supporting refrigeration equipment.

This is easy to understand, just as controlled nuclear fusion requires a superconducting material in the outer ring to control the plasma inside the chamber, so the collider also needs a strong magnetic field formed by the superconducting material to accelerate the particles ejected from the launch gun.

The third part is the most critical part of the detector.

This is the core component of the LHC, and there are a total of seven experimental detectors.

Among them, the most well-known detector is the detector called ATLAS for short, its full name in Chinese is "hypertorus instrument".

With a total length of 44 meters, a circular diameter of 25 meters, and a weight of 7,000 tons, the device could fit two Boeing 737 airliners with about 150 passengers on board.

The God particle, announced in 2012, was discovered by this detector.

In addition, there are CMS compact μ coil detectors, LHC bottom quark detectors, full-section elastic scattering detectors TOTEM, and many more.

For Xu Chuan, there are not many things he wants to study, and those things like particle acceleration rings, particle acceleration pipes, and vacuum strong magnetic pipes don't need him to study.

His main research direction is detectors.

To be precise, it is a detector for the observation of dark matter and dark energy.

This is one of the core conditions for winning the competition with CERN.

After the discovery of the Higgs boson in 2012, the last big gap in the Standard Model has been filled, and the rest of the things, such as the four-quark particle and the five-quark particle, are almost all corner and corner discoveries.

The development of the field of high-energy physics has not been in any direction for 12 years.

Neutrinos, gravitational waves, cosmic rays, and all sorts of other things popped up during that time, and there was nothing that was being studied through the collider.

This didn't change until he discovered inert neutrinos.

This is the first particle beyond the Standard Model, and it can be said that it is the most important direction of research in the field of high-energy physics.

In the competition between CERN and Huaguo, whoever can discover the full picture of inert neutrinos first, or the first to find something related to dark matter and dark energy, will win the competition.

For CERN, the advantage is that they have more advanced detector technology in their hands, as well as sufficient experimental experience and a large number of experimental scientists.

And for Huaguo, the advantage is in him.

As a scholar who discovered inert neutrinos and dark matter dark energy in his previous life, no one knows better than him about the properties of these particles and what they appear on detectors.

It can be said that as long as the collider and the detector can capture their traces, he can stably find clues from the cumbersome and complex collision data and lock on to the target.

However, compared to CERN, detector technology and experience are their shortcomings.

After all, the former has been a holy place for physics in the past ten years, gathering a large number of physicists, engineers and other scientific research and technical personnel.

Flipping through the information in his hand, Xu Chuan suddenly remembered another thing.

In his last life, he heard that his motherland had developed a dark matter particle detection satellite for dark matter and dark energy detection.

If I'm not mistaken, it seems to be called "Goku".

Wukong is the name of Monkey King in the classical masterpiece "Journey to the West", "Wu" has the meaning of comprehension, and "Wukong" has the meaning of comprehension and exploration of space;

On the other hand, Wukong's fiery eyes are like the detectors of dark matter particle detection satellites, which can identify traces of dark matter in the vast space.

Perhaps, he could go to the National Space Science Center of the Academy of Sciences to learn about this technology?

As he was thinking, the phone on his desk vibrate.

Coming back to his senses, Xu Chuan picked up his mobile phone from the table and looked at the caller number, the number starting with 049.

This area code, not a domestic phone, was made from the Germanic state.

With a slight slide of his thumb on the screen, Xu Chuan connected the phone: "Hey, hello, who is it?" ”

On the phone, a smiling voice came, "Hello Professor Xu, I'm Martin Grechel. ”

Hearing this somewhat familiar voice, Xu Chuan reacted quickly, and said with a smile: "Secretary-General, don't come unharmed, I haven't heard from you for a long time." ”

Martin Grechel, member of the Executive Committee and Secretary General of the International Mathematical Union, is an old Germanic man who looks a lot like the bald eagle, the national bird of the United States.

When the International Mathematical Congress was held in 18, the two met.

Martin Glechel laughed, "But I've been hearing rumors and news about you all the time. ”

"I haven't seen it for a few years, and the seven millennial problems have been picked up by two by one person, and I believe that the Yang-Mills existential and quality gap problems will not last long, maybe this year, you will master the three major millennial problems alone."

"In the past, if anyone had told me that someone in the future would be able to solve the three millennial problems on their own, I would have shaken my jaw and couldn't believe it."

Xu Chuan smiled and said modestly: "It's just luck and inspiration." I wonder what the Secretary-General called me today? ”

Martin Grechel shook his head and said with a smile: "You are too modest. ”

After a slight pause, he restrained his smile and continued: "That's the case, Xu, I called here this time, mainly because there are two things." ”

"First of all, about the International Mathematical Congress to be held in Tsarist Russia this year, the International Mathematical Union would like to invite you to attend the conference as a special guest and award presenter to present awards to those Fields Medal winners."

Hearing this, Xu Chuan frowned slightly.

He hasn't been out for several years, and the last time he went abroad was when he went to Sweden to receive the Nobel Prize in 18 years.

It's not that he can't go out, as long as he doesn't go to the United States and North America, if he wants to, there is no big problem with going out for a short time.

It's just that compared to others, it will be very troublesome for him to go out.

Whether it's diplomacy or security, it's going to be quite a toss-up.

Therefore, he has never bothered the country.

After thinking for a while, he didn't think about how to speak, and on the other side, Martin Grechel continued: "Of course, Xu, we know that your situation may be special, but this meeting is held in Tsarist Russia. For Huaguo, this should be a friendly neighbor, and I believe they will also guarantee your safety. ”

"And for this meeting, I also called you in advance to communicate, and the time in the middle can facilitate your motherland to deal with it to a certain extent."

"In addition, there are some reports and special circumstances about you at this conference that require your personal presence, and believe me, it is far more important to participate in this international congress of mathematicians than not to participate."

Hearing this, Xu Chuan thought for a while, but did not immediately agree, he said: "I will think about this matter carefully, what about the second thing?" ”

Martin Grechel laughs: "The second thing is about this year's IMO International Mathematical Olympiad. ”

"In the past, you have also participated in international mathematics competitions, and this year's 63rd competition in Oslo, Norway, we would like to invite you as a special person to come up with a problem and put it in the final competition for the assessment of all talented young people."

"If you can't go to Norway to do the question on the spot, you can do it in China, and I will arrange someone to go to your side to pick up the question in person."

Hearing the second thing, Xu Chuan nodded with a smile and said, "This is no problem, I can provide a competition question." ”

After a slight pause, he smiled and joked: "It's just that the International Mathematical Union believes in me so much?" If you don't go to the scene, you can come up with the question, so you're not afraid that I will leak it in advance? ”

The topics of the IMO competition are provided by the participating countries of the host country, and the host country forms a committee to select the candidate topics from the submitted topics.

Team leaders from all countries arrive a few days before the team members to discuss questions and answers.

As a special guest like him, it is estimated that there are not many in the entire IMO competition, and it may even be the first time that he has done it.

On the other side, Martin Grechel laughed and said, "I think mathematicians all over the world are recognized for your academic character, and we all agree that you will not do such a thing." ”

Xu Chuan smiled and nodded, "Of course." ”

After a pause, he restrained his expression and said solemnly: "I swear in the name of mathematics that no one else will know the content of this math problem except me before the IMO competition. ”

Martin Grechel nodded seriously and said, "Then this matter will trouble you." ”

"Also, with regard to the International Congress of Mathematicians to be held in St. Petersburg, Tsarist Russia in July this year, we are very much looking forward to seeing you at this mathematical conference."

"For the sake of mathematics, I hope you can think about communicating with your country."

"After all, for the mathematical community, you are the label of this era, the dream that everyone is hoping for and trying to get closer."

Xu Chuan nodded and replied seriously: "Well, I'll think about it, and if there is any news, I will reply to you as soon as possible." ”

PS: The second more asks for a monthly pass!
