From University Lecturer to Chief Academician

Xue Wenzhuo was originally in a good mood. He crossed his legs in the office, drinking coffee and watching TV.

Academician Tian Guilin came over and said hello.

It's no big deal.

He said clearly that the program Wang Hao made analyzed the characteristics of the particles, and as a result, several people questioned it, as if they had done something wrong.

This made Xue Wenzhuo very upset.

Although he is a university professor and a physicist, he can be included in the ranks of scientists, but scientists also have temper. What is questionable?

As for what "couldn't be done ten years ago", it doesn't mean that it can't be done now.

Hasn't the Kakutani conjecture been proved by Professor Wang Hao?

Professor Wang Hao still has a lot of mathematical achievements, and he has also studied many algorithms. What's the big deal about him making a program to assist in the analysis of particle characteristics?

Xue Wenzhuo also had a temper. He took a few people to the computer, opened the program to test it, and told them how to use it. Then he said angrily, "If you don't believe me, just try it. This is the program."

"It's okay to use the program to test, but not to copy the code!"

Xue Wenzhuo felt more and more depressed when he thought about it, even in front of Tian Guilin, his tone was a little bit bad.

Academician, so what?

Tian Guilin is an academician of the Institute of High Energy, and he is a professor of Xijing Jiaotong University. He is not here to participate in the spectrometer detection experiment, and they are completely irrelevant.

A few people found that Xue Wenzhuo's tone was bad, but they didn't care too much. They also knew that what they did was a bit annoying when they came to question him.

But, they just don't believe it.

In fact, the difference lies in experience and work experience. Several of them are experts from the Institute of High Energy, engaged in work related to electron-positron colliders. They have been doing research, hoping to use computer means to simplify the analysis process, but most of the analysis has failed. The method is completed by computer.

The same is true internationally.

Most of the initial data had to be manually classified, and calculations could only quickly screen out those more obvious particle signals.

For example, photons.

Most of the photon data is obvious, and the photons can be screened out with a simple filter.

Other particles are relatively more difficult, especially for those similar particles, there is no way to directly distinguish them from the collected information, and it still needs to be calculated manually.

Now hearing that Wang Hao has designed a program that can sieve the characteristics of particles, it naturally feels very incredible.

That's what they've been doing and haven't been able to do.

The next few people were busy around the program on the computer. They entered some data for verification, and then calculated it manually, and they made a surprising discussion, "This group is correct!"

"Academician Tian, ​​this group is also correct, but I miscalculated one of the figures."

"There is an error here, but it's not necessarily true. The data is very vague. I'm not sure what the particle is."

"It seems that the result is very accurate..."

There were voices of repressed and amazed narrations, accompanied by occasional shouts.

Xue Wenzhuo sat beside him with his toes up. He only watched the operations of a few people to prevent them from copying the code and doing things like verification.

He couldn't help but feel a little proud, "I said it's okay a long time ago, but you just don't believe it. If you can't do it, doesn't it mean that others can't do it?"

"We've all used this program to analyze Group F data, and the error rate is very low, what's there to question?"

Xue Wenzhuo has been watching from the side.

Several people gathered around the computer to verify for a long time, and discussed it in a low voice. Finally, someone came over and asked with a blushing face, "Professor Xue, can we copy this program and study it?"

"no!"

Xue Wenzhuo shook his head immediately, "I've said it all, this is a program designed by Professor Wang Hao, I have no right to let you copy it away."

Tian Guilin also came over.

He knew that other people didn't have that much face, so only he said that Xue Wenzhuo would let go, so he still said, "Professor Xue, look, this program of yours is of no use to you, can you copy it?" Give us..."

Xue Wenzhuo continued to shake his head, but he still stood up and said, "Professor Tian, ​​what I just said is the truth. This is a program designed by Professor Wang Hao. I can't let you take away other people's things, can I?"

"Or else..."

Xue Wenzhuo thought for a while and said, "I'll call Professor Wang Hao and ask."

"Okay, then ask." Tian Guilin heard that there was still a turnaround, so he quickly asked Xue Wenzhuo to make a call.

Soon, the call was connected.

There was a panting voice and a strong wind on the phone, and Wang Hao shouted, "Professor Xue, what's the matter? I'm..."

The signal is broken.

It took a long time before a sentence came, "Speak? Sorry, I'm at the Great Wall, and the signal is not good."

"There is something..."

The signal on the phone was obviously choppy.

"It's like this. Academician Qu from Group Seven wants your code. I'm asking if you can copy it and study it."

Xue Wenzhuo said it twice in a row, still shouting at the top of his voice.

As a result, there was only one sentence from the opposite side, "I can't hear what you said, can you wait for me to talk about something!"

"Beep beep beep~~"

Xue Wenzhuo put down the phone in embarrassment, looked at Tian Guilin and said, "Why don't I ask Professor Wang Hao when he comes back?"

Tian Guilin was also a little depressed. He even asked for help, but Xue Wenzhuo didn't let go. He called Wang Hao, but the other party's signal was not good and he didn't reply.

What are you still doing here?

Tian Guilin didn't say anything, just walked away with a wave of his hand, he felt that his old face was almost lost.

The others quickly followed.

When he returned to the office area of ​​the seventh group, Tian Guilin immediately said to the others, "That program is very powerful, but how many years have we been doing this work?"

"If you are overtaken by a team from a university this time, how shameful you will be? Think about it for yourself."

"I don't ask for anything else. From now on, everyone must show their attitude. It doesn't matter if the speed is slow, but the quality of the analysis we do must be high."

This sentence speaks to the hearts of many people.

Several of them are professors of the Institute of High Energy and have worked on the electron-positron collider for many years. The other members of the team are at least associate professors of Capital University.

With such a group of people forming a team, can't they keep up with a newly designed program?

They immediately spoke to others, and everyone worked together to continue fighting for the remaining analysis.

...

In fact, there is a reason why people in the seventh group do not believe that they can analyze the characteristics of particles.

One is because many of them have not found a way for many years.

In addition, the program designed by Wang Hao is not a small program.

Although it is nothing to him at all, it contains his understanding of mathematical equations and programming algorithms.

Some of the programs use the idea of ​​effective and irrelevant carry screening algorithm.

The last point is unattainable.

Unless there is an in-depth study of the effective and irrelevant carry screening method, it is not easy to understand his algorithm.

This is mainly because effective and irrelevant carry screening is not popular. Even some people who specialize in research need a deep mathematical foundation to fully understand.

Most of the computer engineers engaged in programming rarely have a very rich theoretical foundation in mathematics.

Herein lies the paradox.

Therefore, even though the effective and irrelevant carry screening method has been published and reported at the Zhucheng International Computer Conference, there are still very few people who can understand and apply it.

The program designed by Wang Hao contains content about solving equations, and part of it involves the method of fuzzy evaluation.

The reason why many people think that particle analysis needs to be done manually is because some equations cannot be solved and can only be evaluated and judged vaguely.

This part is carried out using a very clever algorithm.

The program Wang Hao designed seems to be simple, but in fact, the core algorithm is very difficult, and I hope it is not easy to understand.

Because of this, Tian Guilin and others were very surprised that the program can analyze particle characteristics, and they could not make a program with similar functions.

Wang Hao didn't come back until the next day.

They climbed the Great Wall and walked a long way on it, but He Yi still couldn't stand it first. Wang Hao helped He Yi down, so naturally he didn't have the energy to go back that day.

They slept in a hotel on the Great Wall for one night, and returned to the experimental base after noon the next day.

After returning, Xue Wenzhuo told Wang Hao what Tian Guilin had found.

Wang Hao thought for a while, and said, "It's okay to let them use it. It's better to copy it and study it. We will hand over this program to the Institute of High Energy. They want to study the program, and they can go to the Institute of High Energy after the experiment is over."

Not only Tian Guilin's Seventh Working Group was interested, but everyone else was also interested.

The experimental review team was curious about how quickly the Xijing Jiaotong University team could complete the analysis. After asking Xue Wenzhuo, they found out that they used an analysis program.

Zhang Yifang, academician of the Institute of High Energy, heard that Wang Hao had returned to the base and immediately looked for him.

Zhang Yifang is the general manager of the spectrometer detection project and also the leader of the experimental review team.

After he found Wang Hao, he talked about program analysis and asked, "I already know that the program you designed is very powerful, and it can directly analyze the characteristics of particles."

"Actually, we have also studied the use of computer methods to analyze particle characteristics, but there has been no progress. Can you tell me how to do it? I'm really curious!"

There were a few others listening.

Wang Hao explained indifferently, "I felt that this analysis work was very complicated at the beginning, and many of them could be solved by computer methods."

"Some of them involve solving equations, and they can also be solved by fuzzy calculation."

"Actually, the biggest difficulty lies in the overall analysis. I have used some of my own algorithmic means. You may have heard of it. I have studied a new algorithm called Valid and Don't Care Carry Screening. This method can..."

Wang Hao explained a lot in succession, but the people beside him nodded, but none of them could fully understand.

There are also mathematicians among them, but they are not proficient in computer algorithms, and those who are proficient in computer algorithms are not proficient in mathematics.

However, they still memorized it carefully. According to their level, as long as they go back and study it, they should be able to understand it.

Zhang Yifang came to Wang Hao not just for the particle characteristic analysis program, he wanted Wang Hao to make a related report at the work meeting.

Then, he took Wang Hao to visit the data center.

The electron-positron collider research base has a data center, but it is generally only open to insiders and related research partners.

The team sent by the university wants to enter the data center, they must apply for it, and no one specifically applies to go in and see, it is not very meaningful.

Zhang Yifang also explained their work to Wang Hao along the way.

From the mouth of a physics academician who specializes in spectrometer detection, he can have a deeper understanding of the research on positron-electron collisions and general instrument detection projects.

The biggest achievement of Puyi's detection research is to develop a high-precision measurement method, which can simultaneously measure the decay of positive and negative Cauchy hyperons, hoping to find the 'cp destruction' of hyperon decay. Simply understood, it is The mirror image of the decay is not symmetrical, and it is creating the problem of the positive particle.

But up to now, no “cp violation” of positive-negative Cauchy hyperon decays has been found, even if a large number of positive-negative Cauchy hyperon decays have been tested, there is still no direct evidence of “CP violation”.

"The problem now is that we can only keep doing experiments and keep testing."

Zhang Yifang said, "Our measurement methods are already world-leading, but the problem is that the number of hyperons we have produced is not large. American's Fermilab has an experiment called 'HyperCP', which produces more hyperons than us. Our advantage lies in the low degree of pollution, but the number of hyperons is also very important to discover.”

"In addition, the analysis method is also very important. We not only need accurate measurement, but also need more sophisticated analysis methods. These are the directions of future research."

"Professor Wang, if you are interested in Puyi detection, you can also participate, check the relevant experimental data, and do some related research."

"This kind of research really needs very good data analysis experts..."

Wang Hao understood the reason for Zhang Yifang's enthusiasm.

The particle characteristic analysis program can indeed improve the initial work efficiency of experimental analysis, but in fact, the application is still limited, and it can also be replaced by artificial means, so the importance is not as high as imagined.

Zhang Yifang hopes that he can participate in the data analysis of positive-negative Cauchy hyperon decays. Through a large amount of decay data, it is the goal of the spectrometer detection project to find strong evidence to prove the occurrence of 'CP violation'.

Wang Hao asked, "How do you participate in this project? Isn't it coming to work?"

"Of course not."

Zhang Yifang said with a smile, "As long as you become a cooperation expert of the project, you have the right to view relevant data, enter the intranet to view some reports and materials, as long as you pay attention to confidentiality. If you want to do analysis, you can do it yourself. Many results are It came out like this."

Wang Hao nodded clearly.

Spectrometer detection is not a small project. Relevant scholars have published more than a thousand related papers, and some papers have been published in the journal "Nature". It is impossible for all papers to be published by the project team. There are many cooperative scholars in the project. If you are qualified to view the experimental data, you can draw some conclusions based on the analysis of the experimental data.

Some of these achievements are small, some are large, and some are even based on personal imagination based on data, but in any case, they are also the results of data analysis.

Since it will not affect work and life, but only has one more authority, Wang Hao naturally agrees.

After submitting the particle characteristic analysis task, he also created a new task out of curiosity——

【Task 2】

【Research Project Name: Analysis of CP Violations of Positive and Negative Kosy Hyperons (Difficulty: S). 】

[Inspiration value: 0. 】

When he saw the difficulty of the research project, Wang Hao regretted it a little.

The previous research and development tasks related to the analysis of experimental data were the most difficult and did not exceed level A.

Even data analysis with A-level difficulty is not so easy to do. S-level difficulty, especially with little correlation with your work and life, may take a long time to complete the research.

"However, if the asymmetric decay of hyperons can be found through data analysis, it should be a top particle physics achievement, right?"

"That's kind of interesting."

Wang Hao still had some expectations.

His previous achievements were all in computer and mathematics. Even if he was doing material-related data analysis, it was the result of data mining, not materials science.

Now it is also doing data analysis, but because it is the discovery of new phenomena, it will definitely be attributed to physical results.

...

The experimental analysis work of each team was completed, and the experimental base organized a working meeting.

The acceptance status of the data analysis reports of each division was announced at the meeting.

The other divisions all accept the analysis reports of the corresponding working groups, while the F area is a bit weird, it accepts the analysis reports of the teams of Xijing Jiaotong University and Huzhou University.

Professor Li Zewen, the host of the meeting, announced, "Area F, the upper and lower parts, accept the report of the working group of Xijing Jiaotong University led by Professor Xue Wenzhuo, and the report of the working group of Huzhou University led by Professor Du Qisheng."

Xue Wenzhuo and Du Qisheng suddenly laughed excitedly.

Xue Wenzhuo was still waving at the others. Du Qisheng didn't have such a thick skin. He really didn't do anything, but just used the program designed by Wang Hao.

Suddenly someone next to Xue Wenzhuo said sourly, "Xue Wenzhuo, shouldn't you be called the Xihai University Working Group? You are all relying on Professor Wang Hao, what does it have to do with you?"

"Relying on others is also strength, what do you know?"

Xue Wenzhuo directly turned back, "We, Xi'an Jiaotong University and Xihai University, do not distinguish between each other, and all research is done together."

"You guys are shit luck!"

"Next time there is this kind of research, I will definitely bring Professor Wang Hao over."

At the same time, many people looked at the seventh working group, because among the official working groups, only the seventh working group had no analysis report accepted.

Tian Guilin and the professors next to him blushed a little. They lowered their heads and tried not to speak.

They also tried to do analysis hard, but the final result proved that no matter how hard they tried, the accuracy of manual calculation could not keep up with the program designed by Wang Hao.

What else is there to say?

Fortunately, other people didn't know about it, and they cheered up their spirits and did useless work for several days...

Some of them couldn't help muttering, "You are just lucky, if Wang Hao is in the subordinate team, so are you..."

"The Xi'an Jiaotong University report has an error rate of 0.2%! How do you compare?"

This is the truth.

Among all the accepted analysis reports, the error rate of the Xijing Jiaotong University team is the lowest, and they can be directly hired in any group.

After announcing the employment analysis report, it comes to the stage of task assignment.

This content has nothing to do with college teams.

The meeting lasted for an hour and a half, and everyone took a short rest before arriving at the final team work report stage.

Some team leaders went up to give work reports, and some professors from the Institute of High Energy gave work reports.

When it was the third one, Wang Hao was called by his name.

Professor Li Zewen said on the stage, "Next, I will invite Professor Wang Hao from Xihai University to give a program report on 'Particle Characteristic Analysis'."

He also introduced, "The Xijing Jiaotong University team and the Huzhou University team used this program to do a more refined screening analysis, and the error rate can be reduced to less than 0.2%. This is a very important result of calculation and analysis methods!"

Li Zewen's introduction caused the audience to exclaim.

Many people know that Xijing Jiaotong University quickly completed data analysis because Wang Hao designed a program, but the specific situation is not clear.

They also didn't expect that it would be a program for particle characteristic analysis.

This surprised people in other working groups. Many of them are experts from the Institute of High Energy and have also done a lot of experimental analysis research.

Because of this, they feel incredible.

Particle Characterization Analysis?

How can it be?

In their astonishment, Wang Hao had already walked to the stage of the meeting place. He looked at the hundreds of scholars below, and suddenly smiled expectantly.

This is a big scene.

There are hundreds of scholars, among whom there are five academicians, and the professor level cannot be counted, and the minimum has a doctorate.

How much inspiration can so many top scholars bring?
