From University Lecturer to Chief Academician

Wang Hao spent the next day absorbing knowledge.

He went to the Electron Positron Collision Center again, and with the team of Xijing Jiaotong University, he had a clear understanding of the research purpose of the spectrometer experiment.

The ultimate goal of this research is to solve the mystery of quark matter and find the asymmetric origin of matter and antimatter.

The asymmetry of matter and antimatter is a phenomenon that particle physicists have been looking for. The research first started with the law of "parity non-conservation" proposed by Yang Zhenning and Li Zhengdao. They won the Nobel Prize in Physics for this, "Cosmos It is called the law of non-conservation, which holds that there is a "mirror" space-reflection asymmetry in the weak interaction of particles.

Later, a theory emerged, which believed that the "decay" of positive and negative particles was asymmetrical. During the annihilation process of every billion positive and negative particles, one positive matter particle was left behind, and finally formed all the particles in the universe today. substance.

Because of this, there is only positive matter in the universe, but no antimatter.

Here is an explanation of the origin of the substance.

For decades, particle physicists have been looking for evidence to support their theories, and they did so by studying the phenomenon of 'CP violation'.

'CP Violation', that is, the phenomenon that the decay process of positive particles and antiparticles is different.

The research method of 'CP destruction' is still to study special particles.

The Corsy hyperon produced by the electron-positron collider is a very important research object. Since ten years ago, the team of the electron-positron collider has been studying the decay of the Corsy hyperon.

And to study the Cosy hyperon, it is necessary to study the J/psi particle.

The decay of the J/psi particle will produce a 'positive-anti-Causy hyperon', and then the positive-anti-Causy hyperon will continue to decay until it disappears.

The current experiment is to start the equipment to do a new collision experiment, collect enough data, and use more accurate measurement and analysis methods to do detailed research, hoping to make new discoveries.

After understanding the overall experimental content, Wang Hao still focused on the work of his own team, that is, the work he wanted to participate in. After all, the experimental research was initially completed by a team of hundreds or thousands of people.

In a team of hundreds or thousands of people, the power of one person is very limited.

On the morning of the third day, a new experiment officially started, but except for the staff involved in the experiment, no one else could do anything. They just waited in the room and listened to the buzzing of the machine outside.

The experiment process was not as gorgeous as imagined particle collisions, but the sound was very disturbing.

It is conceivable what happened in the large-scale equipment, but it is impossible to see it, and the people participating in the experiment can only see some bright spots from the detection device.

This is the real particle collision experiment.

It took a long time to prepare for the experiment. In fact, the real experiment took a very short time, and the experimental process was an instantaneous collision, and most of it was spent on the preliminary preparation and particle acceleration.

Soon, the experiment is over.

There was a humming sound from the machinery and equipment, but the sound gradually became weaker.

In the afternoon, the research team held a work assignment meeting. Wang Hao's team went to three people, Xue Wenzhuo, him, and another physics professor Dong Zhihui from Xijing Jiaotong University.

After they entered the conference hall, they sat in a position in the back row, but in front of them was the formal Seventh Working Group, composed of experts from the Institute of High Energy and the Capital University team.

The seventh working group is not a resident team, it is also formed temporarily, but it is relatively too formal. The working group is led by Academician Tian Guilin of the Institute of High Energy.

Among them are two high-energy physics experts and several professors of mathematical physics from Capital University, and the strength of other teams is naturally not at the same level.

They are also responsible for data analysis, and the work includes the content of the Xijing Jiaotong University team.

The seventh working group is the main working group.

There are two subordinate teams, namely the team of Xijing Jiaotong University and the team of Huzhou University.

The two subordinate teams are all patchworks. For example, the Xijing Jiaotong University team comes from three universities, as well as Xihai University and Xijing University of Science and Technology.

The Huzhou University team is similar.

This kind of temporary team formed by universities came here to study, but it is also effective. They each allocated half of the workload of the seventh working group, and the final data analysis will be compared with the data results of the seventh working group.

If the data of the two parties are consistent, the analysis result is naturally no problem.

If it is inconsistent, it is necessary to find out the problem of one of the parties. In most cases, there must be a problem with the improvised team data.

After Xue Wenzhuo and Dong Zhihui sat down, the seventh group in the front row looked back and nodded towards Xue Wenzhuo, and some who knew Dong Zhihui also nodded.

Wang Hao was also looked at several times, but no one recognized him at first, until someone whispered something in front of him, and suddenly several people turned their heads together.

"Professor Wang Hao?" A professor in the front row asked.

Seeing Wang Hao nodding his head, the people next to him became more enthusiastic.

Wang Hao exchanged pleasantries with several people, and the meeting was about to start. He sat in his seat and listened carefully to the content of the work assignment of the meeting. It was still a novelty to participate in this kind of meeting.

During the meeting, Xue Wenzhuo also explained the work of the team, and said with some self-deprecating, "We are marginal players, and the seventh group in front is the main force."

"But we are mainly here to learn, and others have not had this opportunity yet."

Wang Hao didn’t care about the main force and substitutes. It is normal for two teams to do the same data content. Otherwise, only one team would do it, and it would be difficult to find mistakes in the research. He followed to watch the experiment, just came here out of curiosity Circle, and participate in the work by the way.

If it can play a certain role, of course it is the best, and it doesn't matter if it can't play a role.

He wasn't a physicist anyway.

Wang Hao was concerned about the time issue, "How long will this analysis take to complete?"

Xue Wenzhuo said, "Generally three to five days will be enough. If the progress is slow, it will take a week."

This time is still acceptable.

Wang Hao continued to ask, "That is to say, we can leave after finishing the data analysis of this experiment, right?"

"right."

Xue Wenzhuo nodded, "We mainly come here to participate in the experimental analysis work, so that other people can also know how to do similar work. It is best to have results, such as faster completion, such as consistent with the data of the seventh working group. It’s a good performance.”

"Working Group Seven, how long will it take to complete all the analyzes?" Wang Hao asked curiously.

"They have twice as much data as us, but it should be over within five days?" Xue Wenzhuo is also a little uncertain, but generally speaking, the main working group is very strong, even if it is twice as much data, it will be faster Finish.

...

In the afternoon of the experiment, the various work teams began to distribute work downwards.

The Xijing Jiaotong University team is responsible for the upper half of the data in Area F. Several people in the team are involved in the work, so they start to explain to others how to analyze and distribute the work.

The team needs to divide and cooperate. Some people are responsible for the analysis of big highlights, some are responsible for the removal of small data, and most of them are doing the analysis of ordinary data to determine which particles belong to them, and calculate and record relevant detailed data.

He Yi also participated in an experimental analysis work. He is a professor at Xihai University. Naturally, he focused on taking care of Wang Hao and Xiao Xinyu, and explained to them in detail the methods and conditions of data analysis.

After Wang Hao listened to it, he understood most of it, but the specific analysis must be done later. He asked with some doubts, "Can this analysis of ordinary light spots only be calculated manually? I think Some can be directly divided by computer, but some need to be calculated manually."

"What else?" He Yi pursed his lips forcefully, "The difference between many particles is too small, and each situation is different. Only manual calculation can guarantee the accuracy. Anyway, until now, there is no one The method can be sure to complete the analysis of all ordinary light spots."

Wang Hao nodded after thinking, but still felt that the speed was too slow, no wonder it took several days for a team of more than a dozen people.

He thought about it carefully, and simply set up a task to try——

【Task 2】

【R\u0026D project name: Particle analysis of ordinary light spots in the data of F area (difficulty: D). 】

[Inspiration value: 0. 】

so easy!

Wang Hao was a little surprised when he saw the difficulty of the research and development content, but it was normal when he thought about it carefully. He already understood the work.

The current work is to distinguish particles based on experimental data, but distinguishing particles is only one of them, and it is also necessary to calculate the various characteristics reflected.

However, the main difficulty in data analysis of ordinary light spots is to distinguish particles according to their characteristics.

As long as the properties of the particles can be determined, it will be easy to analyze other relevant data, but some of them still need to be calculated manually, but because the properties of the particles can be directly determined, the workload will definitely be greatly reduced, and it is roughly estimated that it can be reduced by more than 80% .

"This research is still worthwhile."

When some people had already started to devote themselves to work, Wang Hao did not start to do analysis, but continued to ask and discuss his own doubts.

He, He Yi, Xiao Xinyu, and another in the group is Deng Xiaoying, a female professor in Xijing Jiaotong University who is around forty.

When Wang Hao kept asking questions and discussing, it would definitely affect the progress of the work. Deng Xiaoying said a little depressed, "Professor Wang, can we analyze it first, and then study it carefully? It doesn't help."

Wang Hao explained, "I'm just here for work now. The data we've been given will probably take me several days to do, so I want to find a good way to help the analysis be completed quickly."

"Is there still such a good way?" Deng Xiaoying's eyes lit up when she heard it. She felt very annoyed when she saw a lot of data displayed on the computer. It would be great if there was a simple way.

He Yi asked suspiciously, "You want to find a simple method, but you can't find it in a day or two, right?"

"That's not necessarily the case, I already have an idea."

Wang Hao said seriously, "Listen to my thoughts first..."

"I am going to design a program that can divide the characteristics of particles. If the division of particle characteristics can be realized, most of the work will be completed."

The others followed suit.

Wang Haodao, "In fact, these data look very complicated, and it is not difficult to analyze them. The main idea is to find..."

He started talking.

Wang Hao is very experienced in data analysis of design programs. Even though the initial inspiration value is '0', he still has a certain idea. During the process of explaining, he found that the inspiration value increased abnormally fast.

The most direct manifestation is that a lot of thoughts and ideas appear in the mind, some of which have never been thought of before, and some of them feel like a sudden flash of inspiration. After thinking about it carefully, they all feel very subtle.

Here is the inspiration!

Different from the effect brought by "The Gift of Teaching", "The Gift of Scientific Research" can increase the inspiration of others, and then filter the correct feedback to your own mind.

This kind of inspiration is different from knowledge and thinking, but it feels very subtle, just like doing a math problem, it is naturally very smooth to solve it step by step, but suddenly you can think of a formula to solve it, and you feel that you have found a shortcut directly.

In the process of explaining, Wang Hao not only had an unusually clear thinking, but because of the influx of some inspiration, he felt that he was really a super genius, and he could think of a more subtle method when he thought of a problem.

This feeling is really good.

Wang Hao was intoxicated and kept talking, until he reached the last step, he reacted and checked the task.

【Task 2】

[Inspiration value: 106. 】

"!!"

"Enough inspiration!"

At this time, the other three people looked at Wang Hao in surprise, because they heard a very targeted program design just now.

From the beginning to the end, every step is very delicate, and the conclusion can be directly analyzed in the end.

They listened carefully, but there were still some puzzles, especially those 'shortcut' methods.

But they can judge that there must be no problem with the program.

So, what are you waiting for?

"Let's start, let's do a program together, I don't think it should be difficult?"

"should be."

"Wang Hao, you are here to assign work." He Yi couldn't wait.

That day, the group of four was busy until nine o'clock in the evening. They just ate a fast food in the middle of the day and kept typing codes in front of the computer.

The next morning, I continued to work hard for an hour, and finally debugged the newly designed program.

"let's start!"

Deng Xiaoying felt a little excited. What she thought was a boring job turned out to be a design program, and they only took a few hours to complete it.

He Yi extracted the data content assigned by the group and entered it as an input file.

Then, the program officially runs.

This screening program is not very complicated. With only ordinary computers, each data analysis takes about one second, but it is definitely much faster than manual work.

Even if some data does not need to consume energy, you can know what the particle is just by looking at it, but the human reaction is definitely not as fast as the computer, and not all the data is obvious. A lot of data needs to be carefully analyzed to know what the particle is .

At this time, the computer analysis speed is reflected.

After the program ran for more than ten minutes, it output a large amount of data, and each data corresponds to a particle, indicating which particle the data belongs to.

That's enough.

The four-person team immediately started to record and calculate other data based on the characteristics of the output particles, and the workload was reduced by more than 70%.

Originally, I had to work ten hours a day, which required four to five days of work, but now it only takes one day to complete.

They also began to devote themselves to work patiently.

In fact, the ideas of several people are very simple, and they can rest after finishing the work in hand.

Data analysis work is a bit boring.

They do come to learn, but they just need to learn something, and don't need to spend a lot of time participating in it, after all, they don't specialize in this research.

The advantages of mathematicians are reflected when they are really invested in data analysis.

As Xue Wenzhuo said, what the experimental team lacks is mathematicians.

Wang Hao's work efficiency is obviously much faster than the other three. Some calculations, especially those involving equations, can be done easily and directly. Others have to think carefully, and occasionally encounter difficult ones and keep them at hand , temporarily give up not to record.

With the support of Wang Hao's super high work efficiency, all the data analysis work has been completed by 4 o'clock in the afternoon.

He Yi couldn't wait to submit the data.

"Huh~~"

"Finally finished!"

"So tired!"

The four of them stood up collectively, stretched their waists long, and couldn't help but feel the ease of finishing the work.

When he walked out of the small workshop and saw that other people were busy, he felt a sense of superiority.

He Yi looked at Wang Hao and asked hesitantly, "Do you want to help others? They are all in the same team."

Deng Xiaoying also looked over.

"Of course, but I'll talk about it after dinner, and now I have to explain it. It's so troublesome."

Wang Hao covered his stomach and complained, "The fast food at noon is really unpalatable. I didn't eat a few bites, and my stomach was almost flat. I'll eat it today...grilled fish, I want it spicy. Grilled fish and rice are a perfect match." !"

"It makes sense!"

"That's right, hurry up!"

"Don't worry about other people, I'm starving to death." Several people quickly walked out, took a taxi to the nearby commercial street, and completely left the rest of the team behind.
