Chapter 459 It’s Just a Common Occurrence

Xu Chuan originally thought that Mr. Yang was trying to persuade him to delay the construction of the large powerful collider. Unexpectedly, after hearing his question, the old man fell silent.

In the living room, the atmosphere was quiet for a while before Mr. Yang breathed a long sigh of relief and said, "If you had asked me this question a few months ago, I would probably still be opposed to the construction."

"But today, to be honest, I'm a little confused."

"Previously, research on the large collider has been going on for nearly a hundred years. After countless experiments and research, it is nearing completion, and the standard model has been built."

"At that time, the remaining task was to verify the standard model and a few conjectures. And the risk of such research being fruitless was very high."

"Therefore, I think that without building a super large collider, there are still other directions in high-energy physics worth exploring. If this money is invested in other more practical research, the benefits may be more considerable and more practical. feasible."

As he spoke, he looked at Xu Chuan, took a deep breath, and continued: "And at that time, I thought I could only see things within the standard model in my life."

"I didn't expect you to bring a new dawn."

"I thought CERN could do it, but it turned out they couldn't do it."

"Now it seems that if you want to completely break the standard model in this era and find an existence beyond it, you probably have the hope."

"Perhaps you haven't reached the top yet in theoretical physics, but the method you have established using mathematics is undoubtedly the most promising."

After a pause, he continued: "But now I still feel that spending 200 billion to build a large collider is a waste of time and money."

"Although controllable nuclear fusion has been realized under your leadership, the country still has a lot of infrastructure that needs to be built, and many places are still poor."

"No one knows how long it will take for breakthroughs in basic science, especially high-energy physics and particle physics, to be transformed into applied technologies."

"In this regard, even if you reach the top, you may not be able to surpass other countries by much."

After hearing Mr. Yang's words, Xu Chuan understood the complicated thoughts in this old man's heart.

In the past, he did resist the construction of the Large Strong Particle Collider. On the one hand, it was out of patriotism and did not want to waste people and money.

After all, two hundred billion is a huge number for China, which has just entered the new century. Even in the 1990s, the country's total annual GDP was only a few trillion.

It is undoubtedly not worth spending a lot of money to build a basic scientific facility that cannot be transformed into the country's own strength or gains in a short period of time.

On the other hand, the path of high-energy physics can be said to have reached the end of this century before the emergence of sterile neutrinos.

Things within the Standard Model have been basically perfected, while things beyond the Standard Model have been impossible to observe in the past.

Under such circumstances, if we build a large strong particle collider, we will gain very little.

However, the situation has changed now. The emergence of sterile neutrinos, particles beyond the standard model, has shocked the entire physics world.

Things beyond the Standard Model are the hopes that the entire physics community has been pursuing.

It can help the scientific community gain a deeper understanding of the entire world and the entire universe.

Dark matter, dark energy, and how to incorporate gravity into the framework of quantum mechanics and physics all need to break through the standard model.

If this discovery is further confirmed, it means that basic physics, which has almost stalled for mankind, has taken a big step forward, and it also indicates that the universe has opened a new window to mankind.

Through this window, there will be a new physical world.

So Mr. Yang was now conflicted and confused.

On the one hand, having come from the 1990s, he knows how difficult it is for the country's economic development. Two hundred billion is not a small number.

On the other hand, it is the inner desire for a new world of physics.

After all, for a physicist, few devices are more fascinating than the Large Strong Particle Collider.

After thinking about this clearly, Xu Chuan smiled and said: "Building a large strong particle collider is my suggestion to the superiors."

"If you want to ask me what I think, I will naturally support it without any reservation."

"I believe Mr. Yang knows how important the Large Strong Particle Collider is to the development of high-energy physics and particle physics."

"As for funding, 200 billion is a lot of money, but if this money is used to open a new world in physics, it will definitely be worth it."

"What's more, controllable nuclear fusion technology has been realized. In the energy sector alone, the annual savings are at least trillions, and 200 billion is just a fraction."

Mr. Yang glanced at him and said softly: "But it is undeniable that this is not a small amount. With a capital of 200 billion, this kind of project is a super project in the world. Can you control it?" "

Xu Chuan coughed lightly and said with a smile: "If we follow the previous exchange rate, 200 billion RMB is actually only 30 billion gold."

"For me, the investment in the controllable nuclear fusion project alone is almost 80 billion meters of gold. When converted, it is almost 550 billion."

As soon as these words were spoken, the living room suddenly became quiet.

The crowd then remembered that although the man in front of them looked young, the projects and funds he had handled were already beyond their reach.

A controlled nuclear fusion project alone could equal two and a half large particle collider projects.

The big projects and big numbers in their eyes were just commonplace for this man.

With a slightly awkward expression, Mr. Qiu forcibly broke the awkward atmosphere and laughed twice before saying, "I forgot about this. For you, 200 billion is indeed not a lot."

On the side, Mr. Yang didn't care too much. He nodded and said, "Since you have the confidence and the ability, I'll leave this to you."

After a pause, he continued, "To be honest, for someone like me who has one foot in the soil, no one knows whether he can open his eyes and see the sun tomorrow. Maybe I can't hold on to see the emergence of the new world."

Mr. Yang's words immediately resonated with the other two old men in the living room.

Even the youngest Mr. Qiu was over 70 years old.

Not to mention Mr. Yang, who will be 100 years old after the last few days of this year.

Although Xu Chuan fully understands it, he can also feel it more or less.

On the side, Pan Deming, who had been silent all this time, said, "It doesn't matter if you can't see it. There are successors and science is always moving forward. That's enough."

After a slight pause, he changed the subject and said, "Speaking of which, it's just right that you came. I was talking to Xu Chuan about his research before."

"He encountered a very troublesome problem in the strongly correlated electron system. Old Yang, you are engaged in condensed matter physics. Do you want to learn more about it?"

Hearing this, Mr. Yang looked up curiously, with some interest in his turbid eyes, and asked, "Strongly correlated electron system? What's the problem?"

Xu Chuan coughed lightly and said, "It's an unexpected discovery when I was studying KL-66 before. I won't bother you, Mr. Yang."

"What? Do you look down on me, an old man who is about to be buried?" Mr. Yang's tone was a little excited, staring at Xu Chuan and said, "I still have some research in condensed matter physics."

Xu Chuan was a little amused. It was true that the older this person got, the weirder his personality became and the more competitive he became.

But then again, there are not many scholars in China who can communicate with him about condensed matter physics.

Since they met by chance, Mr. Pan took the initiative to bring up this matter, so it would be good to communicate.

After thinking for a while, he briefly talked about his research in recent days.

On the side, Mr. Qiu also came over to listen. Although it was a physics question and he was a mathematician, mathematics and physics were often connected, not to mention that his physics ability was not low.

You should know that he was the only person in Harvard University's history who served as a professor of both the Department of Mathematics and the Department of Physics. Although condensed matter physics was not within his research scope, he knew a little about it.

After hearing Xu Chuan's question, Mr. Yang frowned and thought for a while before saying, "Strongly correlated electrons generally refer to materials in which the interaction between electrons is much greater than their kinetic energy. These systems have very rich physical phenomena, such as high-temperature superconductivity, giant magnetoresistance, metal-insulator transition, etc."

"Although I have paid attention to the KL-66 material developed in South Korea, I am too old to do experiments and learn more about it."

"In the absence of specific experimental data, judging from what you said, you want to use this system to calculate the critical magnetic field strength of enhanced superconducting materials. Theoretically, it should be possible, but it is probably very difficult."

"If the Green's function method, density functional theory, dynamic mean field theory and other methods are not applicable normally, I can think of the first problem you are studying. It has surpassed the ordinary strongly correlated electron system and entered the non-equilibrium strongly correlated system."

"Maybe you can try this aspect."

Hearing this, Xu Chuan thought for a while and asked, "Study the electron dynamics behavior of the strongly correlated system in the non-equilibrium state?"

This is indeed a path he has not studied yet.

Mr. Yang nodded and said, "I don't know if you have studied this, but if not, you can give it a try."

After a slight pause, he continued, "In addition, perhaps you can consider the direction of the strong correlation electron system and the strong interaction force. It may not be related to this, but it may help you better understand the properties of electrons and interactions in the strongly correlated system."
