Great Country Academician

On the second day, Xu Chuan finally got Wei Teng's reply.

"A very beautiful proof method and thesis. The mathematical problems in the proof process are quite quintessential."

"If you haven't decided which journal to submit this paper to, then I recommend "Physical Review" to you. Its D series is very suitable for this paper, and it is a semi-monthly journal, and the review speed is faster. If you see your paper published in the journal as soon as possible."

"In addition, I applied for the LHC's proton accelerator for you to solve this problem. The time is on the 25th of this month. Remember to prepare things like visas and passports."

The reply email was very simple, only three sentences in total, but it made Xu Chuan excited in an instant.

In the old professor's three sentences, one praised the paper, one sentence recommended him for submission, and the third sentence informed him of his application for the use of the proton accelerator.

Among them, the last sentence that caught his attention the most was the application for the use of the proton accelerator.

This is the most critical thing.

As for who the old professor recommends him to submit papers to, it is the same as his choice.

"Physical Review" is an academic journal in the United States, founded in 1893.

The journal publishes the latest research results and scientific reviews in all aspects of physics. It is published by the American Physical Society and is divided into sub-journals such as ABCDE.

Area A is atomic, molecular and optical physics, area B is condensed matter physics, material physics, area C is nuclear physics, area D is particle, field, gravity, cosmological physics, etc.

In addition, there are various aspects of physics such as statistical physics and nonlinear physics.

It can be said that "Physical Review" covers all branches of physics, regardless of popular ones.

However, its requirements for papers are not very high. As long as the paper is creative enough and the argument is clear, it can be submitted for review or even published.

This is a good thing for academic research, but it also causes its impact factor to be low, and some papers are flooded.

However, its overall article quality is still higher than other academic journals.

Because publishing in the "Physical Review" requires articles, the articles must be creative enough or solve some of the more important physical problems.

Many major discoveries in physics have also been published in "Physical Review", such as the quantum Hall effect, gravitational waves and so on.

Of course, in the past two years, "Physical Review" has also begun to limit the number of articles published in order to seek to increase the impact factor within a certain range.

Overall, though, it fits the proton radius puzzle quite well.

After submitting the paper to Physical Review, all that was left was to wait.

Although there are many review editors for "Physical Review", it still takes a lot of time to complete the review of a paper that can be said to be "significant".

This is not a problem of a certain journal, but a common response of all top journals when facing top papers.

It takes a long time for them to ensure that the papers submitted to them have no problems and can be published in journals.

Just like Xu Chuan's "The Xu-Weyl-Berry Theorem Accurately Calculating the Parameter Information Method of Distant Celestial Objects" submitted by Xu Chuan to the "Annual Review of Astronomy and Astrophysics", it has been two or three months now, and it has not yet been officially published. journal.

It can be seen how long it takes for a top SCI paper to be published in a journal.

However, the opportunity for the weak Weyl-Berry conjecture to be published in a journal in just over a month is simply irreplaceable.

For this, Xu Chuan has nothing to do, this is the rule of the academic world, and it is also a necessary process to ensure scientific accuracy.

Even if Einstein traveled over to write a thesis, I believe it needs to be reviewed.

So after delivering the thesis, Xu Chuan returned to his normal life at Princeton University.

On the one hand, I follow Professor Deligne to learn the knowledge of number theory and differential equations, and on the other hand, I listen to the lectures of other professors.

As for his leisure and entertainment time, it is far less than other Princeton students, or almost none.

He has almost never been to the business cards and invitations of various clubs he has received before.

The second Princeton study after rebirth was even more thorny than the first time before rebirth.

Who made him double cultivation in 'name' this time?

Compared with domestic universities, Princeton's doctoral degree has many more classrooms.

Although a doctorate is not learned, you can't get a doctorate just by "learning" existing knowledge, but you can't do it without studying.

Especially the two courses of mathematics and physics are different from other subjects.

If you want to achieve considerable achievements in the two fields of mathematics and physics, you have to go step by step from the path walked by the predecessors.

Start with the simplest set or category, and go to the problem that needs to be solved.

You need to use the "definition theorem" to prove that a long chain of logic can be strung together, and many concepts need to be added to form a network of concepts.

To complete a result, such as proving a theorem, you need to master all the concepts in this network, otherwise you will not understand what you write.

This is the minimum requirement for knowledge, but often it already straddles several areas in mathematics.

No exceptions, that's fair.

A genius may be able to find a shortcut to skip some details faster, but the most primitive accumulation cannot be skipped anyway.

The days passed day by day, and the time soon came to mid-July.

After confirming with Chen Zhengping that his experiment would start on the 18th, Xu Chuan asked Professor Deligne for leave again, and then bought a ticket to fly to Europe.

It is much easier to go to Europe from Princeton than to return to China.

Just a few hours is enough without jet lag.

When he arrived in Switzerland, Xu Chuan called his mentor, took a taxi according to the location and found the hotel smoothly.

The city Chen Zhengping lived in was Geneva, and the hotel he chose was a five-star international hotel. Anyway, accommodation and other things can be reimbursed, so there is no need to save too much.

By the way, he came to Europe this time, whether it was air tickets or accommodation, he was also reimbursed with Chen Zhengping.

Of course, he can also choose to reimburse Princeton, and I believe that both Deligne and Witten will be happy to apply for the travel funds for him.

Arriving at the hotel smoothly, in the lobby, just as Xu Chuan was about to go to the front desk to check in, a young man with a Chinese appearance walked over.

"Brother Xu Chuan?"

The familiar Chinese made Xu Chuan look over curiously, and the figure in sight made him feel a little familiar, but he couldn't remember who it was for a while.

After confirming that he did not find the wrong person, the young man grinned and said, "Hello, my name is Qi Xishao. I studied physics with Chen Zhengping's tutor in the early years."

"Hello, Senior Brother Qi." Xu Chuan greeted quickly.

After such an introduction, he quickly remembered who this person was.

Qi Xishao, a researcher in condensed matter physics and high energy physics.

In 2015, the LHC's Large Hadron Collider bottom quark experiment discovered two new pentaquark particles, confirming the prediction for half a century: "There are actually many types of pentaquark particles."

In this discovery, the senior brother Qi, who was still an intern at the time, was responsible for part of the data analysis work.

But physics is not the same as mathematics.

A mathematician can count forever with a piece of paper and a pen.

But in physical experiments, individual strength, especially this kind of large-scale scientific research experiment project involving the cooperation of dozens of countries, the calculation of one person is too insignificant for the entire project.

However, the results of this research also successfully allowed this Senior Brother Qi to successfully become an official researcher of the European Nuclear Research Center LHC Cooperation Organization.

Don't underestimate the title of this official researcher. With the age of this senior brother Qi in his early thirties, he can be said to be one of the proper leaders among the younger generation of high-energy physics in the domestic physics world.

Although science knows no borders, CERN's LHC cooperation rarely recruits Chinese nationals as their researchers.

Interns are rarely recruited, let alone formal ones.

Those who are qualified to come to CERN to do experiments, not to mention academicians in China, are also well-known top physics experts.

Being able to become an official researcher of the LHC cooperation organization in his early thirties, this senior brother Qi is still very capable.

"Little brother, this is your first time here."

Downstairs in the hotel, after checking in, Qi Xishao smiled and led Xu Chuan upstairs to the hotel.

Xu Chuan nodded. If it is only counted in this life, it is indeed the first time for him to come here.

Geneva is known as the "City of Peace".

Historically, John Calvin and other Protestants who were persecuted in their own country received asylum here. Rousseau, Voltaire, Byron, etc. started to fight for human rights in Geneva; there is also the great proletarian revolutionist Lenin, also They all worked hard for the realization of their ideals in the "City of Peace".

Today, there are more than 200 specialized agencies of the United Nations and various international organizations gathered in this city.

Such as the International Labor Organization, the United Nations Refugee Agency, the International Red Cross Headquarters, the World Health Organization, the Women's Peace and Freedom Alliance, the International Telecommunication Union, the World Intellectual Property Organization, the International Meteorological Organization, the International Organization for Standardization...etc.

It can be said to be quite legendary.

Of course, this also has something to do with Switzerland, a permanent neutral country.

It is a pity that in the future, this permanent neutral country will eventually break its reputation of permanent neutrality.

Hearing this, Qi Xishao smiled and said, "If you have time, you should take a stroll. There are many famous classics here, especially the St. Pierre Cathedral in the old city. If you have time, you can go to pray."

"Pray? Brother Qi, do you believe in religion?" Xu Chuan asked curiously.

"No, I'm a non-denominational." Qi Xishao shrugged.

Hearing this, Xu Chuan immediately understood.

This is probably the characteristic of the Chinese people, and they must bow to everyone they see.

The two chatted all the way up the elevator, and soon came to the seventh floor.

Their tutor Chen Zhengping and some other physics experts and professors from Huaguo basically lived on this floor.

Knock on the door, and soon there was movement inside.

"Teacher, I brought him here."

"teacher."

Xu Chuan and Qi Xishao greeted at the same time, Chen Zhengping smiled and let them into the room.

"Sit down and come in for tea."

Chen Zhengping smiled and boiled a pot of water and brewed two cups of hot tea: "You two should have known each other just now, right? I don't need to introduce you."

"This is my former student, Qi Xishao, who is now an official researcher of the LHC collaboration."

"Xu Chuan, my current student, is currently studying at Princeton."

After talking about not much introduction, Chen Zhengping still smiled and introduced each other to the two.

After exchanging pleasantries, Chen Zhengping looked at Xu Chuan and asked, "This time, do you still want to apply for an intern in the Huaguo Research Group of ATLAS? Or are you following Wei Teng?"

Xu Chuan thought for a while and said, "Sorry, teacher, I'm afraid I haven't joined the research team in our country. On the 25th of this month, Mentor Wei Teng applied for a proton accelerator for me. To study the mystery of the proton radius."

Chen Zhengping smiled and said: "It's okay, it's okay, no one else can ask for such an opportunity. But then again, how sure are you to solve this problem this time?"

Xu Chuan: "Solving the mystery of the proton radius may not be possible for the time being, unless I can calculate the radius of the proton simply from first-principle calculations without using any experimental data."

"But obviously this is not what I can do. What I can do this time is to use that proton accelerator to verify the data used in my thesis multiple times."

On the side, Qi Xishao suddenly smiled and interjected: "Junior Brother Xu, you did something big this time."

Hearing this, Xu Chuan looked over suspiciously.

Qi Xishao smiled and said: "Whether the radius of a proton is 0.87 femtometer or 0.84 femtometer is a matter of endless debate in the physics world. Your paper, at least, can bring hundreds of millions of meters of gold to particle physics." New research funding."

"But~"

After a pause, Senior Brother Qi smiled narrowly, and continued: "But I'm afraid there will be many stubborn old guys who will trouble you. They firmly believe that a large proton radius is the truth. Get ready and wait for you The experiment is completed, and you probably have a lot of trouble."

"At least, that bad old man Richie Flick won't let you go."

The corner of Xu Chuan's mouth twitched, what does this have to do with him.

What is the radius of the proton?

He just "slightly" pushed the real value ahead of time.
