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

Academician Tian Guilin came over and greeted him.

It's not a big deal.

He said plainly that Wang Hao's program analyzed the characteristics of particles, and as a result, several people were questioned, as if they had done something wrong.

This made Xue Wenzhuo very unhappy.

Although he is a university professor and a physicist, he can be classified as a scientist, but scientists also have tempers, and the data analysis report they made was clearly handed in, and the verification also said that the error rate was below 0.2%, what else is there to question?

As for 'I couldn't have done it 10 years ago', it doesn't mean I can't do it now.

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

Professor Wang Hao has a lot of mathematical achievements, and has also studied a lot of algorithms, he made a program to help analyze the characteristics of particles, what's the big deal?

Xue Wenzhuo also has a temper, he took a few people over to the computer, opened the program to check it, and told them how to use it, and then said angrily, "If you don't believe it, just try it, just this program." ”

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

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

Academician, so what?

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

A few people found that Xue Wenzhuo's tone was not good, but they didn't care too much, and they also knew that they had come over to question and do something a little annoying.

However, they just don't believe it.

In fact, the difference lies in the experience and work experience, several of them are experts in the Institute of High Energy Studies, engaged in the work related to the positron and negative electron collider, they have been researching, hoping to use computer means to simplify the analysis process, and as a result, most of the analysis cannot be done with computers.

This is also true internationally.

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

For example, photons.

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

Other particles are relatively more difficult, especially those similar particles, there is no way to directly distinguish from the collected information, and they still have to rely on manual calculation.

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

That's what they've been doing, but 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 used manual calculations, and they sent out a very surprised discussion, "This group is correct!" ”

"Academician Tian, this group is also correct, and there is one data that I calculated wrongly."

"There's a mistake here, but it's not necessarily, it's a blurry data, and it's not sure what the exact particle is."

"It seems that the results are accurate......

A suppressed narrative of exclamation, accompanied by the occasional chant.

Xue Wenzhuo sat next to him on tiptoe, he only watched the operation of a few people, preventing them from copying the code and verifying it at will.

He couldn't help but feel a little proud in his heart, "I said no problem a long time ago, you just don't believe it." Just because you can't do it doesn't mean others can't? ”

"We've all analyzed the data of Group F with this program, and the error rate is very low, what else is there to question?"

Xue Wenzhuo has been watching from the side.

Several people surrounded the computer for a long time to verify, and discussed in a whisper, and finally someone came over, blushing and asking, "Professor Xue, can we copy this program and study it?" ”

"No way!"

Xue Wenzhuo immediately shook his head, "I said it, this is a program designed by Professor Wang Hao, and I don't have the right to let you copy it." ”

Tian Guilin also walked over.

He knew that other people's faces were not so big, so he would only let go when he said Xue Wenzhuo, so he still opened his mouth, "Professor Xue, you see, your program is useless to you, can you make a copy to 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 other people's things, right?" ”

"Or ...... it else"

Xue Wenzhuo thought for a moment 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 on the other side of the phone, and there was a heavy wind, and I heard Wang Hao shouting, "Professor Xue, what's the matter?" I'm ...... now."

The signal is broken.

It took a long time for a sentence to come, "Speak?" Sorry, I'm in the Great Wall and the signal is not good. ”

"Something......"

The signal on the other side of the phone was noticeably intermittent.

"That's right. Academician Qu of the seventh group wants you to copy this code, ask if you can copy it, and study it. ”

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

As a result, there was only one sentence on the other side, "I can't hear what you say, can you wait for me to go back and talk about it!" ”

"Doodoo~~"

Xue Wenzhuo put down the phone a little embarrassed, looked at Tian Guilin and said, "Otherwise, when Professor Wang Hao comes back, I'll ask him again?" ”

Tian Guilin was also a little depressed, he opened his mouth to beg for help, Xue Wenzhuo just didn't let go, and called Wang Hao, but the other party's signal was not good and there was no reply.

So what are you doing here?

Tian Guilin didn't say anything more, he shook his hand and left directly, he felt that his old face was about to be lost.

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 surpassed by a university team this time, will you lose face? Think for yourselves. ”

"I don't ask for anything else, from now on, everyone has to show an 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 at the Institute of High Energy Studies, and they have worked around the positron collider for many years, and the rest of the team is at least an associate professor at Capital University.

Such a group of people forming a team, together still can't catch up with a newly designed program?

They immediately spoke to the others, and together they continued to fight for the rest of the analysis.

……

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

One is that many of them haven't figured out how to do it for 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, as well as his understanding of program algorithms.

Some of these programs make use of the idea of effective and irrelevant carry screening algorithms.

This last point is unattainable.

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

This is mainly due to the fact that effective and irrelevant carry screening is not widespread, and even for some people who specialize in research, a deep mathematical foundation is required to fully understand it.

Most computer engineers who are engaged in programming rarely have a very strong foundation in mathematical theory.

That's 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 some of them involve fuzzy evaluation methods.

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

This part is carried out using a very clever algorithm.

Wang Hao's program seems to be simple, but in fact, the difficulty of the core algorithm is very high, and it is not easy to understand.

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

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

They went to climb the Great Wall and walked a long, long way on it, but He Yi couldn't stand it first, Wang Hao helped He Yi down, and 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 coming back, Xue Wenzhuo told Wang Hao about what Tian Guilin had found.

Wang Hao thought for a while and said, "It's okay for them to use it, it's better to copy it for research." We finally handed over this program to the Institute of High Energy, and they wanted to study the program and find the Institute when the experiment was over. ”

It was not only Tian Guilin's Working Group VII who was interested, but others were also interested.

The experimental review team was very curious that the Xijing Jiaotong University team could quickly complete the analysis, and asked Xue Wenzhuo to find out that they had used an analysis program.

Academician Zhang Yifang of the Institute of High Energy immediately came over when he heard that Wang Hao had returned to the base.

Zhang Yifang is the general person in charge of the spectrometer detection project and the person in charge of the experimental review team.

After he found Wang Hao, he talked about program analysis and asked, "I already know, 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 means 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 other people listening.

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

"Some of them involve solving equations, which can also be solved by fuzzy calculations."

"In fact, the biggest difficulty is in the overall analysis, I use some of my own algorithms, you may have heard of it, I have studied a new algorithm, called effective and irrelevant carry screening, this method can be ......"

Wang Hao explained a lot in a row, but the people next to him nodded their heads, 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 by heart, and at their level, they should be able to understand it as long as they go back and study it.

Zhang Yifang came to Wang Hao not simply for the program of particle characterization analysis, he wanted Wang Hao to make a relevant report at the work meeting.

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

The Positron Collider research base has a data center, but it is generally only open to insiders and related research partners.

If the team sent by the university wants to enter the data center, it must apply, and no one specifically applies to enter it, which is not a meaningful thing.

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

From the mouth of a physicist who specializes in spectrometer detection, we can have a deeper understanding of the research on positron collision and general instrument detection projects.

The biggest achievement of the Puyi detection research is to develop a high-precision measurement method, which can measure the decay of positive and negative Cosi hyperons at the same time, hoping to find the 'cp destruction' of hyperon decay, which is simply understood as the asymmetry of the decay mirror and the problem of creating positive particles.

However, up to now, no 'cp destruction' of positive-negative Cosi hyperon decay has been found, and even if a large number of positive-negative Cosi hyperon decay have been examined, no direct evidence of 'CP destruction' has been found.

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

Zhang Yifang said, "Our measurement methods have been world-leading, but the problem is that the number of hyperons we make is not large, Ameriken's Fermi Lab, there is an experiment called 'HyperCP', which produces a thousand times more hyperons than us, our advantage is that the degree of pollution is low, but if you want to make a discovery, the number of hyperons is also very important." ”

"In addition, the analytical method is also very important, we not only need accurate measurements, but also more sophisticated analytical methods, which are the direction of future research."

"Professor Wang, if you are interested in general detection, you can also participate, view the relevant experimental data, and do relevant research."

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

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

Particle characterization programs can indeed improve the initial efficiency of experimental analysis, but in fact, the application is still limited, and it can also be replaced by humans, and the importance is not as high as imagined.

Zhang Yifang hopes to participate in the data analysis of positive-negative Corsi hyperon decay. Through a large amount of decay data, finding strong evidence of 'CP destruction' is the goal of the spectrometer detection project.

Wang Hao asked, "How do you participate in this project?" It's not going to work, is it? ”

"Of course not."

Zhang Yifang said with a smile, "As long as you become a cooperative 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 the analysis, you can do it yourself, and a lot of results come out like this. ”

Wang Hao nodded knowingly.

Spectrometer detection is not a small project, relevant scholars have published more than 1,000 related papers, and some papers have been published in the journal Nature, papers cannot be published by the project team, the project has many cooperative scholars, qualified to view the experimental data, you can analyze the experimental data, to study and analyze to draw some conclusions.

Some of these results are small, some are large, and some are even personal imaginations 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 one more authority, Wang Hao naturally agreed.

After submitting the particle characterization task, he also set up a new task with curiosity -

[Task 2]

[Research Project Title: Analysis of CP Destruction of Positive and Negative Corsi Hyperons (Difficulty: S.)] 】

[Inspiration value: 0.] 】

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

In the past, the R&D task related to experimental data analysis was the most difficult and did not exceed grade A.

Even if it is an A-level data analysis, it is not so easy to do it, and the S-level difficulty, especially if it is not related to one's work life, can take a long time to complete the research.

"But if we can really find the decay asymmetry of hyperons through data analysis, it should be a top-level particle physics achievement, right?"

"It's kind of interesting."

Wang Hao still has some expectations.

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

Now I am 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 al-Qaida organization held a working meeting.

At the meeting, the acceptance of the data analysis reports of each sub-district was announced.

The other divisions are all the analysis reports of the corresponding working groups, and the F area is a little weird, and the analysis reports of the teams from Xijing Jiaotong University and Huzhou University are hired.

Professor Li Zewen, the presiding officer of the meeting, announced, "Area F, the upper and lower halves, 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 will be accepted. ”

Xue Wenzhuo and Du Qisheng suddenly laughed excitedly.

Xue Wenzhuo also waved at the others, Du Qisheng's face was not so thick, he really didn't do anything, he just used the program designed by Wang Hao.

Someone next to him suddenly said to Xue Wenzhuo sourly, "Xue Wenzhuo, shouldn't you call the Xihai University working group?" It's all Professor Wang Hao, what does it have to do with you? ”

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

Xue Wenzhuo replied directly, "Our Xi'an Jiaotong University and Xihai University, regardless of each other, all research is together." ”

"You're shit luck!"

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

At the same time, many people looked to Working Group VII, because among the formal working groups, only Working Group VII did not have any analytical reports.

Tian Guilin and several professors next to him were a little red, and they lowered their heads and tried not to speak.

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

What else is there to say about this?

Fortunately, the others didn't know about it, and they still cheered up for it and did it for days in a row......

Some of them couldn't help but mutter, "You are lucky, if there is Wang Hao in the subordinate team, you will be the same......"

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

It's the truth.

In all the analysis reports of the hires, the Xijing Jiaotong University team has the lowest error rate and can be directly hired in any group.

After the announcement of the acceptance of the analysis report, it is time for the assignment of work tasks.

This has nothing to do with the university team.

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

The team leader came up to make a work report, and there were also professors from the Institute of High Energy Studies who made a work report.

When it came to the third, Wang Hao was called by name.

Professor Li Zewen said on the stage, "I would like to invite Professor Wang Hao of Xihai University to give a report on the program of 'particle characterization'. ”

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

Li Zewen's introduction caused exclamations at the venue.

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 didn't expect it to be a program for particle characterization.

This surprised the other working groups, many of whom were experts from the Institute of High Energy Studies, and had also done a lot of experimental analysis.

That's why they feel incredible.

Particle characterization?

How can it be?

In their surprise, Wang Hao had already walked to the stage of the venue, and he looked at the hundreds of scholars below, and suddenly showed an expectant smile.

It's a big scene.

There are hundreds of scholars, including five academicians, and the number of professors is innumerable, and the minimum is a doctorate.

How much inspiration can so many top scholars bring?
