Chapter 769 CTV Interview

In three days, Xu Chuan finalized the two major module technology research and development forces of plasma and electromagnetic deflection shield at the Energy Research Institute.

The person in charge of plasma wall research and development is naturally the thin and weak Luo Ming wearing glasses, and the person in charge of magnetic polariton electromagnetic field research and development is a middle-aged researcher named "Li Kaichang" selected from the Institute of Aerospace Research.

As early as the research on aerospace engines, Li Kaichang was one of the main scientific researchers at the time.

The most important components of aerospace engines are ionization acceleration fields and spiral magnetic fields, which are undoubtedly the core of aerospace engines.

And the strong magnetic regulator and electrode ion generator inside the engine are developed by Li Kaichang.

Xu Chuan is still relieved to hand over the technology related to the magnetic field to him.

As for himself, judging from the work situation in 2024, he has no time to take charge of these things personally.

First of all, there is the competition between CERN and CRHPC. Whether it is the verification of the strong electric unified theory or the detection and search of inert neutrinos and dark matter, he needs to lead it personally.

Compared with plasma and electromagnetic deflection shield, in theoretical physics, apart from him, there is really no soul figure in China who can carry the banner.

If Mr. Yang Zhenning was 50 or 60 years younger, it might be okay, but he is now 102 years old.

If the report on the theory of strong-electric unification was not a meeting that a physicist could not miss, Mr. Yang would not have traveled thousands of miles from Beijing to Nanjing.

For the standard model, Yang-Mills theory can withstand experimental and time verification, and it has pioneering and epoch-making significance.

The theory of strong-electric unification has also been expanded on this basis. Whether it is strong interaction or symmetry breaking coupling constants and other calculation prediction data are completed based on this.

However, time waits for no one, and this old man is now 102 years old.

It is said that the waves behind push the waves ahead, and each wave is higher than the other, but for the domestic physics community, without him, many things really cannot be done and cannot be promoted.

For example, the construction of the CRHPC Circular Strong Particle Collider, although the Physics Society helped to promote it, for the top management, there was no one else who had the real influence to prompt them to make this decision by investing hundreds of billions of dollars.

Including the subsequent verification of the strong electric unified theory and the detection of inert neutrinos and dark matter, without his presence, these works cannot be carried out at all, but the speed of advancement will probably be more than one level slower.

In today's fierce competition between CERN and CRHPC, whoever can seize these results first will have a great reputation.

If CERN can make these results first, its status as a holy place in the physics world will be maintained.

And if CRHPC can take the lead, it means that there will be an organization in the physics world that can share the same status with CERN.

As for leading, at present, it can only be said that CRHPC still has a long way to go if CERN does not make a big mistake.

In other words, the CRHPC circular collider will have a chance only if it makes major achievements and discoveries in the field beyond the LH-LHC energy level.

After all, they have been operating for decades, and many Western countries have advantages in this basic science field. If you want to pull those physicists over, you can only say that the road is long and the journey is long.

In addition to the work in the fields of high-energy physics and particle physics, the development of the aerospace field, such as the construction of the lunar outpost scientific research station base and the exploration of Mars, also requires him to preside over the overall situation.

This is not that there is no one in the domestic aerospace field, but that he cannot give up the dominant position of Xinghai Research Institute in the aerospace field to others.

After all, the development of the space shuttle also involves his subsequent exploration and transformation plan for Mars.

On the basis of the possibility of transforming Mars into another planet of life, he will never give up the most core aerospace resources.

Only by mastering the right to speak on aerospace resources can he have the opportunity to do what he wants to do.

Three days passed quickly, and the interviewers from CTV arrived as scheduled.

In the office of Xinghai Research Institute, Xu Chuan met the interview team of C Media. The person in charge of interviewing him is an old acquaintance.

Sun Yutong, the beautiful reporter who has been interviewing him since the Crafford Award.

"Hello, Professor Xu."

CTV reporter Sun Yutong, who was wearing a white business suit, came up to greet him with a smile, and stretched out her hand to gently shake hands with Xu Chuan: "We meet again."

After shaking hands, Xu Chuan smiled and said, "Long time no see, reporter Sun."

Knowing that this person is usually busy with research, Sun Yutong, who was in charge of the interview, did not waste time on greetings, and quickly brought the topic to the interview.

"The interview may take up a little time, please trouble you."

"During the interview, we will ask some questions about physics research. If there are any of these questions that are not convenient to answer, Academician Xu, you can just tell me the next one, and the interview videos released at that time will be edited."

Xu Chuan smiled and nodded, saying, "Then let's get started."

After sitting down on the sofa, Sun Yutong adjusted her sitting posture with a very friendly smile on her face. After signaling the photographer next to her to get ready, she looked at Xu Chuan and said:

"I am honored to have this opportunity to interview you. I believe that not only me, but also the viewers sitting in front of the TV will be very curious about your research work."

"For example, I believe that many viewers have heard about and understood the report on the unified theory of strong electricity that you held at NTU a few days ago."

"But for this theory that can change the present and future of the entire physics world, I think most viewers are like me. It is difficult to have a specific understanding of it, and it is difficult to concretely feel its significance. So it can Could you please give us a brief introduction to your work, Academician Xu?"

Hearing this question, Xu Chuan smiled and said, "For most ordinary people, talking about mathematical formulas and complex theories on how to calculate the unification of strong electricity may make people more confused."

"If we want something like a rough unified theory of strong electricity, we need to understand the background of the Standard Model and some high-energy physics theory."

After a pause, he thought for a moment and then continued: "In terms of today's physics, the origin of the universe we live in is undoubtedly the 'Big Bang Theory' that is more convincing."

"That is, the universe was originally a singularity with extremely high density and high temperature. More than 10 billion years ago, a big bang occurred at this singularity. The big bang caused the energy and matter in the singularity to scatter out, and the universe continued to expand. Expansion, the temperature also dropped accordingly, and later all galaxies, stars, planets and even life appeared in the universe. "

"Including the gravity, strong force, weak force, and electromagnetic force that we are familiar with, in today's physics, they all appeared after the Big Bang."

"To put it simply, we can think of the universe after the Big Bang as a primitive sea of ​​fire full of energy. Its temperature and energy are very high. On this basis, all the elementary particles we have discovered with the help of contemporary equipment They can extract enough energy from the fireball to turn into real particles and wander around in the fireball."

"At that point, they were truly equivalent, and all the fundamental interactions were equally strong and long-range, not just similar."

"But as the universe expanded and the temperature of this sea of ​​energy dropped, these particles began to lose the ability to obtain energy, and then gathered together, evolving into today's gravity, strong nuclear force, weak nuclear force, electromagnetic force, etc. wait."

"The unified theory of strong electricity is to find out how high an energy level we need so that the three forces of the strong nuclear force, the weak nuclear force, and the electromagnetic force will become the same form of expression, just as I described at the beginning The same particles in the sea of ​​primordial energy.”

Sun Yutong smiled and said: "This sounds very interesting, it feels like we are reaching the same destination through different paths."

After a slight pause, she then asked: "Now that you have completed the unified theory of strong electricity, what do you think of the future of physics? What will it be like?"

Hearing this question, Xu Chuan thought for a moment, shook his head and replied: "As for the future of physics, to be honest, this question is not easy to answer."

Hearing this, Sun Yutong immediately turned his gaze over, with a look in his eyes indicating whether he should cut off this section first.

Xu Chuan smiled and continued: "The question of the future of physics is too broad, and our understanding of the current universe is too little."

"Even if my unified theory of strong electricity is verified to be correct through experiments, we still have a series of unsolved mysteries such as gravity, possible dark matter, dark energy, the origin of the mass of neutrinos, etc. Even in future exploration "It is not impossible for us to find other energy or matter in the universe."

"While talking about this, I'm afraid I can't give an answer."

After a pause, he continued with a smile: "But in the short term, we must first verify the unified theory of strong electricity, and then explore possible substances such as dark matter and dark energy, and finally gravity. The source is judged and integrated into the strong electricity theory."

Sun Yutong: "This sounds indeed exciting, but for most ordinary people, these things seem to be very far away. Can you give us some concrete explanations about the impact of the development of these theoretical physics on the development of our civilization and society? meaning?”

Hearing this question, Xu Chuan smiled and said, "In fact, this is not the first time I have heard and seen this question."

"For many people, the point of doing research in theoretical physics is a difficult thing to figure out."

"Because in the eyes of many people, whether it is the research on the unified theory of strong electricity or the construction of large strong particle colliders such as CRHPC and LHC, it is difficult to bring direct development to today's society."

"And a group of the most intelligent scholars of our time have invested huge social resources in undertakings just to satisfy their "desire for knowledge"?"

Speaking of this, Xu Chuan glanced at Sun Yutong with a smile, then at the camera, and continued: "In 1854, Riemann proposed the preliminary idea of ​​Riemannian geometry. In 1905, Einstein published the special theory of relativity. In 1916, Einstein published his general theory of relativity, which used Riemannian geometry as a core mathematical tool."

"That's the theory."

"In 1957, the first artificial satellite Sputnik 1 was successfully launched; in 1959, the first satellite positioning system Transit began to be developed; in 1978, the first GPS satellite was successfully launched."

"This is the application."

"When developing GPS satellites, researchers and scholars discovered that according to the special theory of relativity published by Einstein in 1905, due to the speed of movement, the atomic clock on the satellite will be 7 microseconds slower than the atomic clock on the ground every day."

"According to the general theory of relativity published in 1916, due to different positions in the gravitational field, the atomic clock on the satellite will be 45 microseconds faster per day than the atomic clock on the ground."

"In other words, if the GPS positioning system does not rely on clock pulse signals with an interval of 20-30 nanoseconds for calculation and positioning, and does not calibrate the time, its positioning position will drift. The drift distance is about 10 kilometers per day. "

"Without Riemannian geometry and the theory of relativity, there would be no global satellite positioning system."

Smiling, he looked at the camera and asked: "So, standing in 1854, 1905, or 1916, can people imagine the use of theories such as Riemannian geometry and relativity?"

"Every theory, when it was born, probably could not have imagined its impact on today's daily life."

"For subjects such as theoretical physics and theoretical mathematics, what they study is not science as people imagine, but a kind of 'feasibility'."

"Theories allow us to understand the nature of how the world works and tell people what is feasible and what is not feasible; then engineers in the engineering field use these theories to efficiently build our living environment."

"They complement each other, and many things move from theory to practice."

"Of course, compared to applications, theoretical physics has indeed gone further, and it will be practiced for decades or even further in the future."

"And currently we can't see its use, which doesn't mean it has no value. It's just that we can't realize its value now."

“So, if applied technology is now, then theory is the future.”

“Which direction does it guide us in the future?”

PS: I originally agreed to have double updates today, but when I woke up early this morning, I found that I seemed to have a cold or something. My tonsils were inflamed and red, my nose was blocked, my brain was even more foggy, and my whole body was sore and backache.

I asked for leave and stayed at home for a day without going to work. I went to bed in the morning and got up in the afternoon to grind out four thousand words. I'm sorry, I broke my promise. I promised to add more chapters and make up for it later. I went to bed first. I hope It'll be fine tomorrow.
