At present, there are many research centers for high-energy particle research in the world, but there are only eight high-energy particle research institutes with international status, which are: Fermi National Accelerator Laboratory (fermilab) in the United States, CERN (CERN), Institute of High Energy Physics of the Chinese Academy of Sciences (IHEP), Japan High Energy Accelerator Research Institute (KEK), Brookhaven National Laboratory (BNL) in the United States, SCLA National Accelerator Laboratory in the United States, German Electron Synchrotron (DESY) and the Budker Institute of Nuclear Physics of the Russian Academy of Sciences (BINP). These eight institutions are collectively known as the world's eight high-energy particle research centers, or eight particle accelerator research centers.

Among them, the Beijing Large Positron Collider, which belongs to the Institute of High Energy Physics of the Chinese Academy of Sciences, is its main research machine. Peking University, Shuimu, Nanda, University of Science and Technology of China, Zhongshan, Fudan, Jiaotong University, etc. are closely related to IHEP in the research of high-energy particles, and the data analysis of high-energy particle physics puts forward high requirements for mathematics, so the connection with the mathematics majors of various partner universities is also very strong, which is also the main reason for Professor Hu and Professor Zhou to get acquainted.

Although it is not important for scientists to know each other at the top level, in general, each discipline often forms an academic circle because of the different directions of research. People in the circle may know each other, and if different circles want to know each other, then a certain amount of cooperation and opportunities are essential. The understanding of Professor Hu and Professor Zhou meets the above conditions.

In a series of introductions by Professor Hu to Professor Zhou, Junxin clearly understood that Professor Hu actually respected Professor Zhou very much. This not only shows that Professor Zhou's academic research skills are quite profound, but also leaves a deep impression on Professor Hu in terms of life.

Professor Zhou is also a talent who has returned from abroad, but unlike most people, most Chinese scientists either have the experience of studying in Europe, or have the energy to study in the Soviet Union, and very few purely study in the United States. Even Mr. Qian Xuesen has not always stayed at the University of California, but I heard Professor Hu say that Professor Zhou is a talent who has never been to other countries since studying outside the United States.

The agreed time with Professor Zhou was four o'clock in the afternoon of the next day, so after sending Gu Mengxue away, Junxin continued to collect what Professor Zhou had been doing, that is, to build a world-class high-energy particle collider, so as to build a physics high-energy research institute with first-class research level.

Naturally, Junxin quickly found all the information about BEPC in a pile of information.

In the afternoon of the next day, Junxin came to Professor Hu's office with the arrival of time, and it was in this office that Junxin met Professor Zhou, who is currently the head of the Department of Physics at Mizuki University.

"Hello Professor Hu, hello Professor Zhou!" Junxin greeted the two elders very politely.

"Haha, Jun is here, sit down!" Professor Hu excitedly sat Junxin down.

Junxin didn't say anything polite, he was already very familiar with Professor Hu, so he was basically no longer polite when they met. After Junxin sat down, Junxin looked at Professor Zhou carefully. Professor Zhou actually looks very ordinary, and even has a peasant's unique atmosphere, thinking that because he has been criticized, squatted in the cowshed, and went to the countryside to work as a farmer, the whole person seems a little ordinary. But when you see the sagity in his eyes, you can't help but be in awe and be in awe of his wise eyes.

This reminded Junxin of the scene of his meeting with Professor Edward Witten. The same is that the appearance is ordinary to the public, but that kind of wisdom will always be remembered in people's hearts.

"Is it Junxin?" Professor Zhou asked a little hesitantly.

"It's good to be called Junxin, why do you want to add a small one?" Junxin was a little powerless to complain about Professor Zhou's title, and after slandering in his heart, he quickly nodded: "You know me too?" I'm Junxin, because I want to ask you for some research questions, but I'm afraid that it would be a bit rude to rush to ask for advice, so I know you through Professor Hu's relationship, please don't mind. ”

"Hehe, I didn't expect that someone like me would come to inquire, I was really flattered!" Professor Zhou smiled a little bitterly and said. During this period of time, because of the repeated verification and discussion of the BEPC project, there were countless things mixed in during the period, which made Professor Zhou, who has always been mild-mannered, a little anxious. After all, there is no such thing as one of the world's eight high-energy particle research centers, and China still has a long way to go if it wants to become one of them.

"Professor Zhou, you're always laughing!" Jun Xin shook his head and persuaded: "At present, the research booth of high-energy particle physics is getting bigger and bigger, and the funding is also increasing, and it is not easy to build such a large project in China, but since it has been approved above, it will only be a matter of two years." Why should you be in a hurry? After a pause, Junxin continued, "Besides, today's discussion is only for the greater guarantee of the accelerator in the future, isn't it?" ”

Professor Zhou's face looked a little better, but he still complained: "I also know that we can't be in a hurry, the problem is that we can't be in a hurry, and we can't be in a hurry, in this way, it's not false not to make mistakes, but it's basically not enough to catch up with the world's top level." How can there be a reason why an experiment can't go wrong? ”

Junxin listened carefully to Professor Zhou's complaints, and then began to slowly explain his opinion: "You have been waiting for so long, from 72 years to now, eight years, we can hold on and don't care about waiting for a while, but according to the current schedule, I don't think it will take long for the collider to be operational." ”

Professor Zhou nodded with satisfaction, and suddenly said as if he remembered something: "By the way, Xiaojun, what do you say you want to ask me?" I also tried to read a little bit of your math paper, but maybe it was because of my lack of professional knowledge, so I understood it a little. But it stands to reason that you're very talented in mathematics, so why would you suddenly want to go to physics? ”

Junxin glanced at Professor Hu, who was there, and reluctantly repeated what he had said to Professor Hu succinctly.

"That's what it looks like!" Professor Zhou nodded, naturally understanding what Jun Xin meant. However, although he had already agreed in his heart, Professor Zhou, who had a rigorous style, still asked: "I'm not worried about your mathematics, but I don't know how your basic physics is." But I don't think it's that much worse. Well, I'll come up with a few questions, and I'll give you three hours to answer them, and if it's done, I can make up my mind and agree to your request, how about it? ”

Jun Xin didn't even think about it, and directly agreed: "Naturally!" ”
