One, two......

Three, four......

It was not until the eighty-seven articles were downloaded that Chen Zhou stopped searching the literature.

Instead, he devoted himself to studying the downloaded literature.

Between the last experimental data and a large amount of literature, Chen Zhou chose the latter.

In other words, the experimental data that Chen Zhou has not processed until now has to be a little later.

And Professor Friedman, who has never looked for Chen Zhou, will have to wait for a while before Chen Zhou can take the initiative to find him.

The literature downloaded by Chen Zhou almost includes the experimental papers published by the world's major mainstream research laboratories.

It also contains a number of pre-printed papers from the first edition of this website.

Of course, for these preprints, Chen Zhou really only makes a reference.

The time quickly came to noon, and Chen Zhou, who had always been immersed in the literature, also put down the pen in his hand after finishing another piece of literature.

The time that belongs to physics today has passed.

After eating, it's time for math.

"Why don't you start with the Galois theory?"

Chen Zhou, who was sitting at the desk again, habitually took a pen and clicked on some scratch paper.

I looked at the content that I had combed through last night, and then looked at the "linear representation of the Artin L function of the Galois group" which was written on the scratch paper on the side, one of the two major problems left by the old professor Artin, but which Professor Atin called a sub-topic.

In the end, it was decided to start with the Galois theory.

For this theory that is not very familiar, Chen Zhou still admires it a little.

For the mathematician commemorated by this theory, Chen Zhou admired it even more.

The history of mathematics is a history of geniuses, and Galois is undoubtedly the genius of geniuses.

In the five years from the age of 16 to 21, he systematically developed the whimsical idea of replacing calculation with group theory, creating the brilliant Galois theory.

It is no exaggeration to say that the Galois theory is the way to enter modern number theory and even modern mathematics.

In Wiles's proof of Fermat's theorem, the Galois theory was mainly applied.

The only regrettable thing is that Galois's age has stopped forever at 21 years old.

Otherwise, he may well become a man who surpasses the great mathematicians of his time, such as Gauss, Cauchy, and Fourier.

Because, these great mathematicians of that era did not understand Galois's theory.

For example, Abel's paper "There is no general algebraic solution to unary quintal equations" devotes more than 50 pages and a lot of calculations to prove that it is impossible to solve general unary quintal equations in a radical form.

But if we use the Galois theory to prove this.

The argument process is that "the Galois group of the general unary quintile is isomorphic to the total displacement group S5, and S5 is not a solvable group, so the general unary quintile cannot be solved radically." ”

This kind of gap doesn't need to be carefully tasted.

When you see a large number of problems that are difficult to prove through complicated calculations.

When it can be proved concisely and accurately using an ingenious mathematical structure.

The beauty of Galois's theory is embodied.

In Chen Zhou's words, unless he can come up with mathematical tools and mathematical research directions as great as Galois Theory next year.

Otherwise, he really verified a sentence, that is, some people can't catch up even if they are really open......

What's even more terrifying is where Chen Zhou remembers seeing it when the 21-year-old Galois wrote down his main research results on scratch paper with extremely concise, leaping thinking.

No one knows that the Galois theory has been in Galois's mind for more than 1 year.

Of course, Galois probably went with a bigger plug-in......

Chen Zhou soon became immersed in Galois theory.

"Numbers and operations can be combined to form a mathematical structure, which is a more essential, more abstract mathematical structure......"

"When this structure continues to be abstracted away from numerical and conventional operations, the concept of 'group' is formed......"

For the first time, Chen Zhou understood the concept of "group" from this perspective, and he couldn't help but feel a little surprised.

Add to that the concept of rings and domains.

These abstract guys have all appeared.

A group is not something that can be formed casually.

domains, perhaps, are a little more complicated.

And these are the steps that need to be stepped on to climb the peak of the Galois theory.

It is also the content that Chen Zhou is obsessed with at this moment.

"If we take groups, rings, and domains as the starting point, then the expanded domains, radical solvables, and radical towers in Galois's theory are ingenious concepts......"

"And the automorphism of the domain, the Galois group and the Galois correspondence, are the stroke of God......"

The pen in Chen Zhou's hand left lines of text on the scratch paper, which matched the mathematics.

The scratch paper also changed from one to two and then to three......

Zhang Zhang was filled.

And these are the proofs of the passage of time.

It took two days for Chen Zhou to focus on Galois theory and give a profound taste.

If anyone sees the scratch paper on which Chen Zhou studied Galois theory.

You will be surprised to find that this guy actually simulates one of Galois's thought processes.

That is, Galois created the idea of the "Galois Theory".

To put it simply, it's about looking at numbers and calculations at a higher level.

Then the concept of groups and domains was formed.

Then, through the method of domain and extended domain, a more accurate mathematical definition of the root formula of the equation is given.

From the study of the domain, it is found that a certain kind of autoisomorphic mapping of the domain corresponds to the displacement of the root of the equation.

Thus the mystery of the solvability of the root formula of the equation is found.

Then he took the key that opened the door to the mystery, that is, the Galois correspondence, and beautifully corresponded the domain column with the group column.

Finally, based on profound logical derivation, the concept of solvable groups is formed.

And it is proved that the root solvability and the Galois group are the equivalence relationship of the solvable group.

Doesn't it sound like a step-by-step process that doesn't take much time?

Actually, it didn't take much time.

It took five years for Galois, but in reality, it probably didn't even take a year.

He created the core of these Galois theories.

When Chen Zhou was studying and researching Galois theory, he also remembered a famous sentence of Galois:

"Jump out of calculations, group operations, and classify them according to their complexity, not appearances......"

After the Galois theory, Chen Zhou turned back to the "Atin L function" of the sub-topic "Linear Representation of the Atin L Function of the Galois Group".

In this way, after returning from Providence, Chen Zhou started a new round of rotational learning mode.

In physics, the literature is combed as a whole.

Rely on the direction of the wrong question set to determine your own research direction and the feasibility of the experiment.

In mathematics, the sub-topic and Gochai go hand in hand.

It's just that the sub-projects progress faster and take more time.

And Gechai can only play soy sauce on the side, and from time to time glance at whether there is any movement in the distribution deconstruction method.

This is not contrary to Chen Zhou's original intention.

Because Chen Zhou is looking for and making up for the knowledge of algebraic geometry.

His aim was to develop distributive deconstruction through the content of algebraic geometry.

So as to solve the answer to the difficult problem of Gochai on the side.

During this time, Yang Yiyi was mainly on LIGO's side.

In the middle of the way, I followed Professor Weiss to Europe for an academic exchange.

In this regard, Yang Yiyi also specially asked Chen Zhou if his mentor had mentioned this matter to him.

Chen Zhou's answer was naturally no.

It had been too long since he had seen Professor Friedman.

Not even an email communication.

Of course, there can be no such thing as academic exchange.

Yang Yiyi was still a little strange when she heard Chen Zhou's answer.

This academic exchange in European physics is mainly based on high-energy physics.

And it's also in charge of CERN, the world's largest particle physics laboratory.

It seems to be a summary of the physics discoveries and research progress in 2016.

In a sense, this is not an inconsequential meeting.

Friedman, as a leading figure in the field of high-energy physics, is likely to participate.

Why didn't you mention it?

Chen Zhou didn't explain much about this, anyway, now he is also addicted to his own rhythm and can't extricate himself.

In addition to not being able to go to Europe to meet Yang Yiyi, Chen Zhou was happy to stay in the dormitory.

Anyway, the academic exchanges hosted by CERN will definitely be able to see the content of the relevant conference later.

And the physics of 2016 can only be said to be fairly stable.

The most striking thing is the gravitational waves, which were discovered last year.

Therefore, although Chen Zhou learned about the academic exchange of European physics in Yang Yiyi.

But he didn't take the initiative to go to Friedman and ask about the situation.

Chen Zhou believes that Friedman will definitely inform him in advance if he has arrangements.

And Friedman never looked for himself from beginning to end, which means that either Friedman took someone else there, or Friedman himself did not go.

Chen Zhou prefers the latter.

For such an old man, and an old scholar who is immersed in his own research, Chen Zhou feels that he is more likely to stay in the office.

Like myself, I am waiting for the relevant CERN meetings.

The facts also confirmed Chen Zhou's suspicion, and after the academic exchange in Europe began, Yang Yiyi told Chen Zhou that she had not seen Professor Friedman.

Moreover, during the academic exchange time in Europe, Friedman did not find Chen Zhou.

After this academic exchange, Yang Yiyi also returned to LIGO.

Chen Zhou once asked Yang Yiyi when she would return to MIT.

But Yang Yiyi herself doesn't know, there is no definite time.

Chen Zhou had no choice but to jokingly say that if he doesn't come back, the next time he comes to MIT will be the next semester......

That's right, as winter gets colder, the time is getting closer to the date of winter break.

When Yang Yiyi heard Chen Zhou's words, she just looked at Chen Zhou in a daze for a while, and then said with a smile: "Then when I come back, we will go home together~"

As Chen Zhou expected, on December 16, CERN took the initiative to publish the content of the last academic conference.

The main thing is what Yang Yiyi said, a review of 2016 and the outlook for the new year.

At the same time, CERN's experimental plan for the next year was also partially revealed.

Chen Zhou is basically in the video with Yang Yiyi, and he has heard Yang Yiyi say it.

There is nothing new.

Moreover, the tone of physics has now largely been set.

Physics inside the Standard Model, and new physics outside of the Standard Model.

Both of these are the core tasks of the current development of physics.

In addition, since it is an academic exchange conference hosted by CERN.

Naturally, it is indispensable to blow a wave of CERN's own deeds.

However, these are exactly what CERN has achieved.

Just like CERN's Large Hadron Collider (LHC) 100m underground, at the end of June this year, the operating brightness reached the original design target, that is, the collision rate of 10^34cm²·s.

In addition, in the first half of 2016, CERN conducted several experiments on the LHC, and the results of the new data obtained from the study of the God particle "Higgs boson", the signal significance of which has exceeded the results of the first phase of the operation.

Also, at the end of 2015, signs of a new particle with a mass of 750 GeV appeared on the LHC, which became the focus of discussion among theoretical physicists.

Unfortunately, with the latest research data this year, the indication is just an illusion caused by statistical fluctuations.

These results or falsifications also show the strength of CERN.

In other words, it heralds the birth of a new physics, which will appear here at CERN.

Despite the lack of new physical signals, the living space of various new physical theories, including supersymmetry theory, has been further compressed.

In addition, neutrino physics, low-energy strong interaction physics, and dark matter search are the places that attract more attention from Chen Zhou.

In neutrino physics, in particular, another Nobel Prize-level achievement may be born.

This is the content of the Italian GERDA experiment report, in which they say that no neutrino-free bin β decay has been detected.

This result is more sensitive than before.

If this decay is detected, it means that the neutrino is its own antiparticle, that is, the Majorana particle.

It's definitely fun enough.

Of course, before that, Chen Zhou's first major topic in the field of physics, "where is the rubber ball", has not yet been accurately landed.

It's just that it's almost there.

Closing the page of CERN's official website, Chen Zhou prepared to return to his own world of rubber balls.

After sorting out the literature for more than half a month, I finally came to the experimental data of this SLAC, and it was time to process the data.

It's finally time to start getting serious.

The previous content can be said to be preparation.

But when it comes to the experimental data, it's really time to set the experimental parameters for the next experiment.

As soon as Chen Zhou opened the information, he heard a knock on the door before he could unfold his favorite scratch paper.

Chen Zhou got up suspiciously and went to open the door.

Outside the door, stood two unexpected people.

After Chen Zhou saw the faces of the two of them, he asked in surprise: "Two senior brothers, when did you come back? In the previous email, you still said that you don't know when you will come back?"

The two people standing in the doorway were none other than Coyle and McIsson, who were also PhDs under Friedman.

The two men had been left behind by Friedman since their last visit to the SLAC lab.

In an email exchange just a week ago, the two of them complained to Chen Zhou that they couldn't come back for Christmas.

As a result, it is not yet Christmas, and both of them have returned.

Hearing Chen Zhou's words, Coyle immediately urged: "We are here to urge you to process the experimental data quickly, but Professor Cross complains to us from time to time. ”

"Said that every time he sent you an email, you said that he was still processing, but after dealing with it for so long, it still didn't seem like there was any progress on your side, and he was really exhausted waiting......"

Chen Zhou was stunned for a moment, and then laughed softly: "Immediately, I will start processing the experimental data immediately, don't rush ......"

Speaking of this Professor Cross, Chen Zhou is actually quite sorry.

Cross is the conscientious type.

After Friedman's trip to the seaside, Cross took his duties as an "elder" seriously.

After all, he came to SLAC before Chen Zhou.

And whether it is qualifications or academic achievements in physics, they are also higher than Chen Zhou.

Therefore, Cross thought that he could take Chen Zhou with him and take fewer detours.

At least not to disappoint Friedman.

Compared to the rest of the people in SLAC, Friedman's arrangement, they can't afford to lose.

Unexpectedly, after Chen Zhou's kid returned to MIT, it was like disappearing.

No news at all.

Only when he took the initiative to send an email to ask, Chen Zhou would tell him "Yes, the data is being processed, I'll send it to you later".

It's almost immutable, it's always this one sentence.

So, Cross was in a hurry and didn't know what to do.

This is what Coyle calls complaining and complaining.

In this regard, Chen Zhou is still quite ashamed.

It is precisely because of Cross's identity that Chen Zhou can't treat him like he treats classmates and friends like Shen Jing and Zhang Yifan.

It is even more impossible to cooperate with Cross in the same way as Yang Yiyi.

If that's the case, Chen Zhou estimates that he can't explain it clearly.

Therefore, Chen Zhou had no choice but to adopt such a delaying strategy.

Wait until you have finished processing the data and hand over a complete "answer sheet".

Then Kross will review it, help with the revisions, check and fill in the gaps, and it's OK.

Chen Zhou sometimes wondered how good it would have been if Cross hadn't been an old man at SLAC and a professor in the physics department.

Then he can summon Cross to check the literature and sort out the information like Shen Jing and Zhang Yifan.

It's a good helper for a lot of work.

Otherwise, I wouldn't have been able to make sufficient preparations until now......

When Chen Zhou's voice fell, Coyle and Mai Xisen glanced at each other, and both of them said in surprise: "You really haven't processed the experimental data yet, right?"

It seemed to them that it had been so long since the end of the experiment.

No matter how slow and procrastinating Chen Zhou is, it is impossible that he has not started the processing of experimental data until now.

Moreover, they have also read Chen Zhou's paper.

Chen Zhou, who has a very high mathematical talent, is an extremely sensitive person to data.

When dealing with experimental data, you should be more handy.

How is it possible, for so long, without any progress at all?

Chen Zhou chuckled softly: "No, I just wrote two data, it should be counted, right?"

Coyle: "......???"

McThesson: "......???"
