Chapter 137 The team is very important, but grilled fish is more important!
Wang Hao spent the next day absorbing knowledge.
He went to the Electron-Positron Collider Center again and worked with the team from Xijing Jiaotong University, where 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 initially began with the law of 'parity non-conservation' proposed by Chenning Yang and Tsung-Dao Lee, for which they won the Nobel Prize in Physics, "parity"
"The law of non-conservation" holds that there is a "mirror" spatial 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 eventually formed all the particles in the universe today.
substance.
Because of this, there is only positive matter in the universe and no antimatter.
This is an explanation of the source of matter.
In recent decades, particle physicists have been looking for evidence to support the theory, and the way they do it is to study the phenomenon of 'CP violation'.
‘CP destruction’ is a phenomenon in which the decay processes of positive particles and antiparticles are different.
The research method of ‘CP destruction’ is still to study special particles.
The Corsi hyperon produced by the electron-positron collider is a very important research object. Since ten years ago, the electron-positron collider team has been studying the decay of the Corsi hyperon.
To study Corsi hyperons, we need to study J/psi particles.
The decay of J/psi particles will produce ‘positive-anti-Corsi hyperons’. After that, the positive-anti-Corsi hyperons will continue to decay until they disappear.
The current experiment is to start the equipment to conduct a new collision experiment, collect enough data, and conduct detailed research with more precise measurement and analysis methods, hoping to make new discoveries.
After understanding the overall experimental content, Wang Hao focused on the work of his team, which was 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 machines outside.
The experimental process was not as gorgeous as expected from the particle collision, and the sound was just very irritating.
You can imagine what is happening in the large equipment, but it is impossible to see it. People participating in the experiment can only see some bright spots from the detection device.
This is a real particle collision experiment.
The preparation for the experiment took a long time. In fact, the real experiment took a very short time, and the experimental process was an instant collision. Most of it was spent on preliminary preparation and particle acceleration.
Soon, the experiment ended.
There was a buzzing sound coming from the machinery, but the sound was obviously getting weaker.
In the afternoon, the research team held a work allocation meeting. Wang Hao's team went to three people, Xue Wenzhuo, and Dong Zhihui, another physics professor from Xijing Jiaotong University.
After they entered the conference hall, they sat in a seat 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 permanent team, it is also temporarily formed, but it is relatively more formal. The working group is led by Academician Tian Guilin of the Institute of High Energy.
There are also two high-energy physics experts and several mathematical physics professors from Capital University. Naturally, their strength is not at the same level as other teams.
They are also responsible for data analysis work, and the work includes the work of the Xijing Jiaotong University team.
The seventh working group is the main working group.
There are two subordinate teams, namely the team from Xijing Jiaotong University and the team from Huzhou University.
The two subordinate teams are all pieced together. For example, the team of Xijing Jiaotong University comes from three universities, as well as Xihai University and Xijing University of Science and Technology.
The Huzhou University team is also very similar.
This kind of temporary team formed by universities is here to study, but it is also effective. Each of them is assigned half of the workload of the Seventh Working Group. The final data analysis will be compared with the data results of the Seventh Working Group.
If the data from both parties are consistent, there will naturally be no problem with the analysis results.
If there is any inconsistency, you need to find out the problem with one of the parties. In most cases, there must be a problem with the temporary team data.
After Xue Wenzhuo and Dong Zhihui sat down, the seventh group of people in the front row looked back and nodded towards Xue Wenzhuo. Some of them who knew Dong Zhihui also nodded.
Wang Hao was also looked at several times. No one recognized him at first, until someone in front of him whispered something, and suddenly several people turned around.
"Professor Wang Hao?" asked a professor in the front row.
Seeing Wang Hao nod, the people next to him suddenly became more enthusiastic.
Wang Hao exchanged greetings with a few people and prepared to start the meeting. He sat in his seat and listened carefully to the work assignments in the meeting. It still felt very novel to participate in this kind of meeting.
During the meeting, Xue Wenzhuo also explained the work of the team and said with some self-deprecation, "We are the marginal players, and the seventh group in front is the main force."
"But we are mainly here to learn. Others don't have this opportunity yet."
Wang Hao didn't care about the main force or the substitute. It was normal for two teams to do the same data content. Otherwise, only one team would do it, and it would be difficult to find errors in the research. He followed to watch the experiment and just came over out of curiosity.
Circle and participate in the work.
If it can play a certain role, of course it's best. If it doesn't, it doesn't matter.
He's not a physicist anyway.
Wang Hao is concerned about the time issue, "How long will it take to complete this analysis?"
Xue Wenzhuo said, "In general, 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, "In other words, we can leave after completing this experimental data analysis, right?"
"right."
Xue Wenzhuo nodded, "We are mainly here to participate in the experimental analysis work, so that others can know how to do similar work. It is best to achieve results, such as completing it faster, such as being consistent with the data of the Seventh Working Group. This
That performance would be great.”
"Working Group 7, how long will it take to complete all the analyses?" Wang Hao asked curiously.
"They have twice as much data as us, but it should be over within five days, right?" Xue Wenzhuo is also a little unsure, but generally speaking, the main working group is very strong, and even if it is twice as much data, it can be done faster.
Finish.
…
In the afternoon of the experiment, each work team 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, and they start to explain to others how to perform the analysis and allocate the work.
The team needs to divide the work and cooperate. Some people are responsible for the analysis of big highlights, some are responsible for the removal of small data, and most people do the analysis of ordinary data to determine what specific particles they belong to, and calculate and record them.
Relevant detailed data.
He Yi also participated in an experimental analysis work. He was 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 situations of analyzing data.
After Wang Hao finished listening, he understood most of it, but the specific analysis must be done later. He asked with some confusion, "Can this kind of analysis of ordinary light points only be calculated manually? I think
Some can be divided directly using computers, but some require manual calculation."
"What else?" He Yi pursed his lips hard, "The differences between many particles are too small, and each situation is different. Only manual calculation can ensure accuracy. Anyway, until now, there is no one
The method can definitely complete the analysis of all ordinary light spots."
Wang Hao thought and nodded, but still felt that the speed was too slow. No wonder a team of more than a dozen people would take several days.
He thought about it carefully and simply created a task to try——
【Task 2】
[R&D project name: F area data ordinary light point particle analysis (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 when he thought about it carefully, it was normal. He already understood the work.
The current job is to distinguish particles based on experimental data, but distinguishing particles is only one of them, and calculations of various reflected characteristics are also required.
However, the main difficulty in data analysis of ordinary light points lies in distinguishing particles based on their characteristics.
As long as the properties of the particles can be determined, it will be easy to analyze other related data. However, some parts still need to be calculated manually. However, because the properties of the particles are directly determined, the workload will definitely be greatly reduced. 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 work, Wang Hao did not start to analyze, but continued to ask questions and discuss his doubts.
He, He Yi, Xiao Xinyu, and another person in the group was Deng Xiaoying, a female professor in her forties at Xijing Jiaotong University.
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? You understand everything, and you are also familiar with the current work."
It’s not helpful.”
Wang Hao explained, "I am here just for work. The data we have been assigned will probably take several days to work on, so I want to find a good way to help the analysis be completed quickly."
"Is there such a good method?" Deng Xiaoying's eyes lit up after hearing this. She felt very irritated when she saw a lot of data displayed on the computer. It would be great if there was a simple method.
He Yi wondered, "If you want to find a simple method, 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 planning to design a program that can divide the characteristics of particles. If I can divide the characteristics of particles, most of the work will be completed."
The others nodded.
Wang Haodao, "Actually, these data look very complicated, and the actual analysis is not difficult. The main idea is to find..."
He began to speak.
Wang Hao is very experienced in data analysis of design programs. Even though the initial inspiration value was ‘0’, he still had a certain idea. During the explanation process, he found that the inspiration value increased abnormally fast.
The most direct manifestation is that a lot of ideas appear in my mind, some of which I have never thought of before, and some of which feel like a sudden flash of inspiration. If you think about it carefully, you will feel that it is very subtle.
This is 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 in your own mind.
This kind of inspiration and knowledge has different ideas, but it feels very subtle, just like doing a math problem. It is naturally very smooth to solve it step by step, but suddenly I can think of a formula to solve it, and I feel like I have found a shortcut.
During Wang Hao's explanation process, not only was his thinking extremely clear, but because of the influx of inspiration, he felt that he was really a super genius, and he could think of more subtle methods when he thought of a problem.
This feeling is really great.
Wang Hao was intoxicated and kept talking. When he reached the last step, he came to his senses and checked the mission.
【Task 2】
[Inspiration value: 106.]
"!!"
“The inspiration is worth enough!”
At this time, the other three people looked at Wang Hao in great surprise, because they had just heard a very targeted programming.
From beginning to end, every step is very subtle, and the conclusion can be directly analyzed in the end.
They listened attentively, but there were still some things they didn't understand, especially the 'shortcut' methods.
But they can judge that there is definitely no problem with the program.
So, what are you waiting for?
"Let's get started. Let's do a program together. I think it shouldn't be difficult, right?"
"should be."
"Wang Hao, here you come to assign work." He Yi couldn't wait.
The foursome were busy until nine o'clock in the evening that day. They just ate some fast food and continued typing code on the computer.
I continued working hard for another hour the next morning, 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 it only took them a few hours to complete it.
He Yi extracted the data content assigned by the team and entered it as an input file.
Then, the program officially runs.
This screening process is not very complicated. It only uses an ordinary computer. Each data analysis takes about a second, but it is definitely much faster than manual processing.
Even if some data does not require any effort and you can tell what particles it is just by looking at it, human reaction is certainly not as fast as a computer, and not all data is obvious. A lot of data requires careful analysis to know what particles it is.
.
This is where the speed of computer analysis comes into play.
The program ran for more than ten minutes and output a large amount of data. Each data corresponded to a particle, indicating what particle the data belonged to.
This is enough.
The four-person team immediately started recording and calculating other data based on the output particle characteristics, and the workload was suddenly reduced by more than 70%.
It used to take four to five days of working ten hours a day, but now it only takes one day to complete it.
They also began to devote themselves to work patiently.
In fact, the ideas of several people are very simple, just finish the work at hand and then rest.
Data analysis work is somewhat boring.
They are indeed here to learn, but they just need to learn something and do not need to spend a lot of time participating in it. After all, they do not specialize in this research.
The advantages of mathematicians are revealed when they are truly involved in data analysis work.
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, while others have to think carefully and occasionally keep them handy when encountering more difficult ones.
, giving up not recording for the time being.
With the support of Wang Hao's super high work efficiency, by about four o'clock in the afternoon, all data analysis work had been completed.
He Yi couldn't wait to submit the data.
"Huh~~"
"Finally finished!"
"So tired!"
The four people stood up collectively and stretched their bodies, feeling relieved that they had completed their work.
When I walked out of the small workroom and saw other people busy, I suddenly felt a sense of superiority.
He Yi looked at Wang Hao and asked hesitantly, "Would you like to help others? We are all on the same team."
Deng Xiaoying also looked over.
"Of course, but we'll wait until after dinner. It's very troublesome to explain now."
Wang Hao clutched his stomach and complained, "The fast food at noon is really bad. I didn't eat a few bites, and I was almost starving. I'm going to eat today... grilled fish, spicy, grilled fish and rice, it's a perfect match."
!”
"That makes sense!"
"You're right, go quickly!"
"Don't worry about other people, I'm starved to death." A few people quickly walked out of the door and took a taxi to a nearby commercial street, completely forgetting the rest of the team.
