From small town scholar to chief scientist

Chapter 254 Some Clues to Dark Matter
After Zhou Yi left,

The leading abbots said to the monks below them:
"In the future, the threshold for recruiting people will be lowered. Undergraduate students only need mathematics students, while postgraduate students only need science majors. Those who are not good at mathematics are not required. It is best to study mathematics."

Several monks in charge of recruiting disciples said:
"Okay, host."

And several Taoist priests looked embarrassed, their Taoist sect didn't have so many requirements,

It's just that after the Buddhist sect does this, the Taoist sect may be even weaker.

After Zhou Yi returned to his room, Peony said in Zhou Yi's ear:

"Master, the signal sent back from the enhanced version of Wukong, the data of low-energy electronic recoil is somewhat abnormal."

Zhou Yi was surprised when he heard the news:
"Could it be that dark matter has been found?"

"No, it may be other high-energy ray sources. Has the data been transmitted to the computer?"

Zhou Yi asked a series of questions.

The enhanced version of Wukong can well reduce the interference of other high-energy ray sources and obtain the most accurate data.

Peony said:

"The data has been sent to the computer, and it is waiting for the master to analyze it and finally draw a conclusion."

Without further ado, Zhou Yi turned on the computer and started working.

What is dark matter, many people do not know.

In the vast Milky Way, in addition to stars, planets and other celestial bodies visible to our naked eyes, there may also be many invisible dark matter.

Many physicists speculate that they do not emit light, and basically do not interact with other substances. Under the observation of ordinary optical means, they are like "invisible".

To put it in simple academic terms, dark matter refers to a class of matter that does not participate in electromagnetic interactions.

Seeing objects through the human eye and most astronomical observations utilize electromagnetic interactions,
Dark matter cannot be detected by electromagnetic waves because it does not participate in electromagnetic interactions.

Then the question arises, since dark matter cannot be found by people, how do people guess that there is dark matter?

This is because astronomers found that there is a contradiction between the mass calculated by the law of gravity and the mass detected by electromagnetic waves,

For this reason, it is assumed that there are a large number of substances that cannot be detected by electromagnetic waves but have gravitational effects in the universe.

In 1931, Dutch astronomer Jan Oort discovered that stars located on the outer edge of the Milky Way were orbiting faster than previously estimated.

The pre-estimated orbital speed is obtained by observing electromagnetic waves, and only includes the gravitational effect of visible matter.

The actual orbital speed is contradictory.

Without changing the law of universal gravitation, in order to explain this contradiction, it is necessary to introduce matter that does not participate in electromagnetic interaction but has gravitational effect, that is, dark matter.

This is where the concept of dark matter comes in.

Then, in 1933, the Swiss-American astronomer Fritz Zwicky used spectral redshifts to measure the speed at which galaxies in the Coma cluster moved relative to the entire cluster.

And use the force theorem to find that the relative motion speed of many galaxies is very high.

The centrifugal force estimated from galaxy velocities is much greater than the gravitational force corresponding to the visible mass of the galaxy cluster.

Therefore, it can be conjectured that there are many unobservable substances in these galaxy clusters, and their masses are large enough to produce gravitational effects that can restrain galaxies moving at high speeds.

Later, many physicists came to similar conclusions,

And the enhanced version of Wukong launched by Zhou Yi is to search for the result of the accidental collision of dark matter particles.

When a pair of dark matter particles collide by chance, they can annihilate, releasing high-energy particles such as electrons, positrons and gamma rays.

If the information of these particles can be accurately "captured", it is possible to reverse the clues of the existence of dark matter.

Now the enhanced version of Wukong has sent back a lot of data.

Zhouyi asked Peony to process these data according to the method used in the world at the beginning,

It was not until today that Peony discovered that the data sent back not long ago was abnormal.

If the data is going well,

Then a new physics may be on the horizon.

A whole new kind of particle will be discovered.

For several days in a row, Zhou Yi was doing high-intensity calculation work with Peony.

Five days later, Zhou Yi calculated the various data through the Boltzmann equation and its total action rate.
obtained its remaining abundance.

Seeing this result, Zhou Yi felt a little frustrated.

"Mad. Is their mathematical model wrong? This abnormal value gives me a strong hunch that it is a new kind of particle.

And it's an inert neutrino. "

Zhou Yi was cursing while replying to the news in recent days.

For the past few days of retreat, students Zheng Keyu and Zhang Jiahui took turns delivering meals.

Why is it not a female student who delivers the meals? Zhou Yi is afraid of causing unnecessary misunderstandings.

And Zhou Yi said a long time ago that female students are not allowed to look for him alone,
Female students must have a partner before they can find him, otherwise there will be some gossip,
Zhou Yi jumped to the Yellow River and couldn't clean it up.

This method is also used by many university professors.

He didn't even dare to stay alone in an office with female students.

These few days are the period for the college entrance examination to fill in the volunteers, Zhou Yi thinks it's okay if he can't do it for a while.

Let's take a look at the situation of filling in the Chongqing Higher Court this year.

There is no rush for this thing, it has been dozens or hundreds of years, and it has not been discovered, and Zhou Yi did not expect to be discovered by himself in a short while.

This unscientific.

Unless the subsequent data is more abnormal, and Zhou Yi innovates a new calculation method, it will be difficult.

These calculation methods are the most accurate models obtained after repeated revisions by top physicists and mathematicians.

It's hard to move a knife.

The news of Zhouyi's retreat quickly attracted the attention of senior officials of the Yuzhou Institute for Advanced Study and the metaphysics community.

Zhou Yi held a meeting, mainly to inquire about the situation of filling out volunteers for the exam.

It is now June 6th, and the voluntary reporting process has long since ended.

Therefore, it is necessary to know what level the future students are in the country.

Although the grades before entering the university are of no reference significance after entering the university,
But it can reflect a student's talent, learning habits and learning concentration from many aspects.

Not long after, a small meeting started.

Xu Youxiang was the executive vice president sent by the Yuzhou government, and also the former vice president of Yuzhou University.

To help Yu Gaoyuan deal with some things.

A research institute similar to a university must have people who can handle things,

It is impossible for everyone to engage in scientific research.

And Xu Youxiang is also the top professor under the academician, with a lot of academic achievements in the past.

There are many reasons for not being selected as an academician.

Finally turned from academics to administration.

At this moment Xu Youxiang said:
"Dean Zhou, all directors and professors, the scores of the students who reported to our Chongqing Higher School this year are the highest in the entire western region.

According to our previous enrollment quota,
TV University, Shu University, Yu University and many other universities are not as high as our score line,

The only ones that can compare with us are the two universities in Shanghai and Huawu.

The group of people with the highest scores is comparable to that of Mizuki University and Shangjing University.

And there are quite a few people in this group, adding up to more than 30 people. "

Everyone is very satisfied with this result. After all, in the first year, a lot of resources were invested in marketing.

The effect is good.

Zhou Yi said:

"Where did these 30 people mainly report?"

Xu Youxiang said:
"It's all math."

Zhou Yi: . .

Although I had guessed, I didn't expect it to be so scary.

"Not only that, tens of thousands of people signed up for our school, but less than 100 students are required by our research institute.
Therefore, after being admitted from high to low, the rest of the people will most likely slip. "

Xu Youxiang said.

Academician Zhang on the side said:
"Actually, many of the students here are quite good. Many of them scored 650 points. We can expand the enrollment appropriately.
The Institute of Physics, Chemistry, Computer and Artificial Intelligence, and Geodynamics all need to expand their enrollment.
Our teachers are enough. "

Zhou Yi hesitated for a while, then said:

"Let's expand the number of recruits for each major, and each major recruits 30 people."

There are 150 people in five majors, which is not too small.

The University of Chinese Academy of Sciences only accepts 400 students each year, and the subject of driving is much more than that of Chongqing University.

"With 150 people, we can almost digest it internally, and it is almost enough for each tutor to lead one or two students.

If the number of tutors increases, we can continue to expand enrollment. "

Academician Zhang Tiande said.

Wang Yifang on the side said:

"Physics can also charge more, because we already have many scholars in physics who want to join.
Including theoretical physicists who have won many awards.In the future, the Institute of Physics must be an academic institution that reaches the world's top cutting-edge. "

Zhou Yi said:

"Let's do this first, and we can expand the enrollment appropriately later."

After the discussion, Zhou Yi said:

"This admission was very successful. These students with the lowest scores can go to Shanghai Jiaotong University, Zheda University, or Aurora University. It is already very successful."

After everyone chatted for a while, Zhou Yi let Wang Yifang stay,

asked:

"Do you know about dark matter?"

Wang Yifang wondered:
"How did your old man come to study particle physics?"

Zhou Yi said:

"Isn't this a study of the nature of the universe? After solving the ABC conjecture, I want to change my taste and rest my mind."

Wang Yifang:?
To rest your brain is to study in another direction?

Have you ever rested like this?

Do you respect people.

Wang Yifang said:

"Of course we know that visible matter in the universe accounts for 4.9%, dark matter accounts for 26.8%, and dark energy accounts for 68.3%.

And we're very supportive of WIMP. "

Zhou Yi smiled when he heard the result, and said:

"Supersymmetry, it's normal for you to support it, maybe the final string theory is right, right?

After all, the hottest WIMP-type dark matter candidates are the lightest supersymmetric particles. "

Wang Yifang laughed awkwardly and said nothing, Zhou Yi said:
"I feel like an inert neutrino is more likely."

Wang Yifang laughed awkwardly and said:
"Professor Zhou, the XENONIT experiment seems to have some data supporting the existence of WIMP,
They detected some excess cases with an experimental confidence of about 3-4 σ. "

Wang Yifang didn't expect Zhou Yi to be so disapproving of string theory, so she could only explain with an embarrassed smile.

After all, he is the one who pays.

Zhou Yi pouted and said:

"It takes at least 5 σ to confirm, it's still early. Maybe it's wrong."

Wang Yifang still said in embarrassment:
"Professor Zhou's theory will be discussed later, let's talk about CEPC."

"Ah."

After Zhou Yi learned about the situation of CEPC, he was ready to continue retreating.

Before July [-]th, Zhou Yi vowed to get it out.

Let those who did not apply for the Chongqing Higher Court regret it.

No one is optimistic about the computer and artificial intelligence of Chongqing University of Higher Education. It is clearly the world's best, but it only sees mathematics.

This made Zhou Yi a little depressed.

As for the construction of CEPC, it is progressing steadily, faster than Zhou Yi thought.

The CEPC was built to help discover dark matter as well.

So Zhou Yi is very concerned about CEPC.

Just when Zhou Yi was about to retreat,
Zhang Jiahui ran in and said:

"Mr. Zhou, those people outside seem to be arguing to see you all the time."

Zhou Yi wondered:
"Who?"

Zhang Jiahui said:
"The group of people who engage in metaphysics. They are waiting for your results."

Zhou Yi said:

"No time, I'm busy later. Let them go back when they have nothing to do, and I will find time to write later."

Zhang Jiahui said:
"Oh, that's fine."

Zhou Yi thought for a while and said:

"Forget it, let's go out and meet them in person."

After Zhou Yi saw them, seeing them looking at him eagerly, Zhou Yi was very embarrassed.

One of the leaders said pitifully:

"Professor Zhou, please, please write the following text. We don't worry about others writing it. You are the guide of this book.
The patriarch of new metaphysics. "

Zhou Yi: . .

Zhou Yi also didn't want to offend them.After all, it is irrational to fight against a circle.

And they have a lot of basic fans, some teenagers who believe in metaphysics do some extreme things,
It may have a bad influence, and it may be possible to organize a group to come to the Chongqing Higher Court to make trouble.

Zhou Yi said:

"I'm really busy, I still have to study the data collected in recent months,

These data may shock the whole world.

Or let my apprentice continue writing?I'll read it myself when the time comes to see if there's a problem. "

Everyone wanted to say more, but when they saw Zhou Yi's expression was wrong, they dared not speak.

They can still distinguish between the achievements that shocked the world, which is more important, and know how Zhou Yi will choose.

The reason why Zhou Yi is so polite is that they supported Zhou Yi and criticized Ma Daoyin online.

Otherwise, Zhou Yi couldn't be so polite.

One of the monks said very respectfully:
"Okay, we understand that Professor Zhou is busy with scientific research, but Professor Zhou should know that this book will surely last forever and be regarded as a classic by countless people.
If it is done by others, it may not be that Professor Zhou has died alone, but someone will be side by side with you. "

It has to be said that these old Taoist priests and monks have a high level of controlling people's hearts.

After hearing this, Zhou Yi said lightly:

"Am I that kind of person? I will write it within half a year. Just wait."

After talking to them, Zhou Yi left directly.

These old things know people too well.

It's better to go back and grab those data.

Zhou Yi felt that no matter what, he had to change the mathematical model before he could make new discoveries.

Or the enhanced version of Wukong can discover more intuitive data.

The discovery of dark matter can not only complete the task, but also establish itself in the physical world in one fell swoop.

At that time, maybe there is still hope for the Dirac Award and the Nobel Prize.

PS: Ask for a monthly pass.
