The Xijing Jiaotong University team works in several offices on the left side of the third floor of an office building.

Adjacent is the Huzhou University team.

Xue Wenzhuo went to the team of Huzhou University to take a look, they are all doing the analysis of the data of the F area, the work content is very similar, and the comparative discussion and exchange are also very meaningful.

When he got back to the office, he saw a file of submitted data displayed on his computer.

"Data analysis summary file? He Yi sent it? Xue Wenzhuo glanced at the content and was immediately very surprised.

The experiment was just completed yesterday, and the work assignment was also yesterday afternoon, and it has only been a full day now, so how can the data analysis summary file be submitted?

Xue Wenzhuo simply pushed the door and walked out, and went to the small office where He Yi, Wang Hao and the other foursome were, he pushed open the door and glanced at it, only to find that it was empty and there was no one inside.

"What about people?"

Xue Wenzhuo muttered a little strangely, and then came back to continue to look at the data file submitted by He Yi.

He roughly glanced at it and knew that all the data of He Yi and Wang Hao's group were already in it.

"Impossible~~"

"How can it be so fast?" Xue Wenzhuo was very puzzled, he found the original document, tried to verify the two data in the report document, and the results were all correct.

He simply walked out of the door and shouted, "Professor Dong! Xiao Zhang! You guys come over and help take a look at this. ”

'Xiao Zhang's name is Zhang Lijun, and he is a doctoral student led by Xue Wenzhuo.

Professor Dong is Dong Zhihui.

After the two came over, they were also very surprised to hear Xue Wenzhuo talk about He Yi's group and the data analysis work had been completed.

Dong Zhihui even said, "It can't be made up, right?" ”

"This can't be, right?" Xue Wenzhuo said, "I just manually measured two data, and the results are correct, let's test them together to see if there is any problem." ”

The three of them immediately began to manually verify.

He Yi's group is responsible for the particle characteristics analysis of ordinary light spots, which is to analyze what particles each small light spot is, and then add other measurement data of small light spots.

The most important of these is to verify the particle properties.

The three people randomly selected some raw data and then manually calculated for each one.

Twenty minutes later, Dong Zhihui said with surprise, "There is no problem with the data I just drawn, only one is wrong, it is a difficult kind of calculation, and the error rate is very low." ”

Zhang Lijun buried his head in the calculations and said, "It's the same on my side, I haven't found any data with errors." ”

Xue Wenzhuo simply stopped writing, and he, like Zhang Lijun, did not find any mistakes, indicating that the quality of this particle characterization analysis data is still very high.

Particle characterization work has a certain fault tolerance rate.

Generally, if the error rate is less than 1%, it is qualified, and the error rate is about 0.5%, which is already very good.

Judging from the data extracted so far, the error rate of this particle characterization data is likely to be less than 0.5%.

Xue Wenzhuo felt a little incredulous, "How did they do it?" Done in a day? So fast? Even with Professor Wang Hao, it's impossible, right? ”

Dong Zhihui and Zhang Lijun also couldn't understand it.

No matter how powerful Wang Hao is, he is just one person, even if he can directly divide the data when he sees it, and the results can be directly obtained from complex calculations, it is impossible to complete all the particle characteristics analysis work in such a short time.

"Ask them!" Dong Zhihui turned around and was about to go to the small office of the foursome.

Xue Wenzhuo reminded, "There is no one in the office, they all went out." ”

Dong Zhihui thought for a while, and immediately took out his mobile phone, "I'll make a call, I have He Yi's phone, ask them what they are doing, come back quickly." ”

When he was about to make a phone call, Zhang Lijun suddenly said, "They're going to have a big dinner." ”

"Huh?"

Xue Wenzhuo and Dong Zhihui looked at it together.

Zhang Lijun showed them the screen of his mobile phone, which displayed the information of the circle of friends.

Deng Xiaoying took a video and posted it to a circle of friends, the content of the video is a large table of dishes, and there is a grilled fish that is delicious when you look at it, and you can smell the fragrance through the screen.

There are also He Yi, Wang Hao and Xiao Xinyu in the picture, they are eating grilled fish and drinking beer, and they seem to be eating very happily.

Xue Wenzhuo watched the whole video, and there was a 'gurgling' sound in his stomach, and he said with some embarrassment, "I didn't eat a few bites of the lunch box at noon, and it's almost time for dinner, right?" ”

"The meal was just delivered, and I have no appetite, and I have no appetite after watching this video."

"Me too, I don't have an appetite ...... either"

The three of them glanced at each other, their expressions a little sad.

……

waited until seven o'clock in the evening before Xue Wenzhuo finally saw He Yi, Wang Hao and others come back.

He walked over with a grief and asked, "How did your group finish so quickly?" ”

"We rushed back in a hurry just to talk about it......" Deng Xiaoying said with a full burp, not seeing the meaning of being in a hurry at all.

Xue Wenzhuo's expression became even more complaining, you are in a hurry to come back?

Eating so much?

Deng Xiaoying continued unconcernedly, "Professor Wang Hao designed a program that can analyze the characteristics of particles, so we completed it quickly. ”

Xue Wenzhuo immediately reacted, "There is still this kind of procedure?" He said and looked at Wang Hao.

Wang Hao nodded lightly and said, "We came back for this, or we would have gone back to the hotel just now." You also use this program to do analysis, you can directly classify the particles, and then fill in the data. ”

"That's great." Xue Wenzhuo was immediately very pleasantly surprised, because the data had already been tested, and he had no doubt about the effectiveness of the program.

This is certainly a program that can greatly improve efficiency and reduce workload.

Xue Wenzhuo followed Wang Hao to the computer to copy the source code, and sighed while trying it out, "Professor Wang, you really gave us a big surprise, this program is too important." ”

"If all the data can be analyzed by the program, we will be able to complete all the work tomorrow and the day after tomorrow."

After Xue Wenzhuo ran the program, he used all the data as the input end, and then output it at one time, he quickly found an efficient way, using a computer to do the calculation, and then let one person operate the specified file, pass it to others respectively, and then continue to the next step of data filling.

When it was the next morning, everyone in the team knew the news, and they didn't have to divide the particle properties again, they just needed to fill in the data and calculate, and the work was relatively much simpler.

Everyone is full of energy and continues to work hard together.

He Yi, Wang Hao and others re-participated, but also shared another part of the team, so that the work could be completed faster.

By noon on the third day, all the data analysis had been completed.

Xue Wenzhuo also summarized the data, and after doing a series of analyses, he stretched his waist and exhaled lightly, and submitted the content with a smile on his face.

Then he walked out of the office and announced, "Our job is done!" ”

"Next, everyone is in the mood to go around, the capital is still worth turning, the Great Wall, the Forbidden City, and the Summer Palace are all going around, you can't come in vain."

"Yay~~!!"

Everyone cheered excitedly.

They came to participate in the data analysis of particle collision experiments, but they didn't expect to be able to play around, because the data analysis work is very heavy, and they are mentally prepared.

As a result, the work ended early, and the extra days became holidays, which is really happy.

……

The speed with which Xijing Jiaotong University has done its work is very surprising.

Normally, a team of less than 20 people can analyze half of the data in a single area, and it takes at least five days to analyze half of the data in a single area.

And that's still the case with speed.

The Xijing Jiaotong University team is a mixed team, many of whom are participating in similar work for the first time, without any experience at all, and the speed of doing analysis is naturally much slower, under normal circumstances, it takes a week to complete.

As a result, just on the afternoon of the third day, the team from Xijing Jiaotong University submitted the data summary report.

The report is submitted to the Experimental Review Committee.

This committee is set up on an ad hoc basis, including academicians and professors of the Institute of High Energy Studies, resident experts of the spectrometer experimental team, and scholars from international cooperation participating institutions.

Tian Guilin is also one of them.

Tian Guilin leads Working Group 7 and is also a member of the Experimental Review Committee.

After the team from Xijing Jiaotong University submitted the data report, he quickly learned the news and was immediately very surprised, "The team from Xijing Jiaotong University, why is it so fast?" ”

"In less than three days, this speed is not normal, huh?"

Tian Guilin wrinkled his brows, a little puzzled.

A professor from Capital University next to him said, "Could it be Wang Hao?" Wang Hao's level of mathematics is top-notch, and he can play a big role in this kind of work. ”

"Impossible."

Tian Guilin suddenly denied, "In this kind of complex analysis work, a person's role is limited, even if he can do calculations faster, but the calculations are only secondary, he is at most faster than others." ”

Tian Guilin couldn't think of a reason for it, so he simply said, "Let's finish the part of the data that the Xijing Jiaotong University team is responsible for first, and compare it with their data." ”

"Data analysis that was done so quickly is likely to be problematic......"

Tian Guilin thought about it and continued, "It's not enough to just pursue fast, but also to pursue stability and precision, the team of Xijing Jiaotong University has little experience, this time we will teach them a lesson and tell them that data analysis, accurate results are more important." ”

……

The other experts of the experimental review committee, Tian Guilin's judgment, were surprised by the rapid submission of the data analysis report by Xijing Jiaotong University.

At the same time, they believe that speed doesn't mean anything, what matters is the accuracy of the analysis.

The Xijing Jiaotong University team is just a 'subordinate second team', probably for the reason of 'fighting for a breath', and wants to complete the work quickly, but it is very difficult to ensure accuracy.

Of course.

The experimental review committee could not make judgments out of imagination, so they still did spot checks.

This test is the same as Xue Wenzhuo's method, which is to randomly select a part of the data for calculation.

Because Working Group 7 was the 'home team', there were only two people to do the calculations at first, but later it was found that most of them were correct, so more people were found to test them.

After two hours of testing, everyone was shocked by the results.

"Particle property classification, error rate is less than 0.2%!"

This error rate is quite staggering.

In fact, it is the same as solving a difficult problem, no one can guarantee that every question will be done correctly, in addition, some questions are very vague, some particles have similar characteristics, and the captured information will be affected by other things, so there is no way to be completely sure what particles are, that is, there is no accurate answer.

Because of this, particle characterization has a certain fault tolerance rate, and less than 1% is qualified.

In general, the error rate of the data submitted by the working group is between 0.5% and 0.8%, as long as it meets the error expectations.

0.2% is an unimaginable number, and it can be said that except for some controversial data, all others are correct, which is equivalent to answering a perfect score.

There is no confidentiality in the initial particle characterization of the experiment, just the initial data analysis, in short, the classification of the experimental data to lay the foundation for the next analysis.

Soon a lot of people knew the news.

Tian Guilin also knew the news for the first time, he felt a little incomprehensible, and at the same time felt very stressed.

The seventh working group is also a temporary team, but they have several experts from high-energy institutes, and there are several long-term related work in the team, and the others are also professors from Capital University.

Several members of Working Group VII were unable to accept the news.

They also analyzed the reasons together, "Although I don't know what's going on, I feel that this time it may be related to Professor Wang Hao of Xihai University." ”

This time, Tian Guilin did not refute again.

The speed and quality of experimental data analysis are fast, which shows that there must be capable and advanced people in the team.

Looking for the team from top to bottom, the reason can only be attributed to Wang Hao, who is an expert in theoretical mathematics and has just completed the proof of the Kakutani conjecture and is recognized as a top mathematician.

A mathematician of this level, doing mathematical analysis work, may have some good way to simplify?

"Fortunately, there is Huzhou University!"

Tian Guilin sighed, "If the two subordinate teams are faster and more high-quality than us, our seventh working group will be meaningless. ”

"What a shame this time!"

The other side.

Du Qisheng, the leader of Huzhou University, approached Xue Wenzhuo, and he also heard that Xijing Jiaotong University had completed the analysis.

Du Qisheng felt very incredible.

The team of Huzhou University, compared with Xijing Jiaotong University, is still a little worse, but it is not too bad, and the tasks assigned by them are similar.

The team of Huzhou University has just completed one-third of it so far, and the team of Xijing Jiaotong University has already completed it.

This efficiency gap is also too great.

Xue Wenzhuo and Du Qisheng are very familiar, so they talked about Wang Hao's research on a program that can be used to analyze the characteristics of particles, and finally called Wang Hao to see if he could help the Huzhou University team conduct an analysis.

Wang Haozheng was walking around the Forbidden City with He Yi and Xiao Xinyu, and directly agreed when he received the call.

The program he designed was specifically for particle characterization analysis, and even for the data of this experiment, which had no commercial value, and was of little significance after the experiment.

If other teams want to use it, they can use it too.

After the Huzhou University team used the program designed by Wang Hao to perform particle characterization, the speed of the analysis immediately doubled, and in less than a day, they completed all the remaining work and submitted the data immediately.

This is the fifth day of the experimental analysis.

After receiving the data submitted by the Huzhou University team, the experimental review committee immediately conducted a test and analysis, and found that the error rate was within 0.5%, which is also a very good particle characterization analysis report.

On top of that, the Huzhou University team was quick to complete the analysis.

Five days doesn't sound fast, but in fact, because the scale of the experiment is slightly larger and the data allocated is a little more, it will take more than a week for the professional team to complete the particle characterization analysis of a zone.

The Huzhou University team is responsible for half of the data in a single district, considering that they are only a 'subordinate' team, many people in the team have come to learn, and it only took five days to complete the analysis of half of the data, and the error rate is still within 0.5%, which is quite amazing in speed and quality.

Tian Guilin was a little calm when he got the news again.

With the precedent of the Xijing Jiaotong University team, the Huzhou University team was a little faster, and it didn't seem to be much in comparison, he still asked, "Did Xijing help Huzhou University?" ”

He thought it was Xijing Jiaotong University, and after finishing the work in hand, he went to help the Huzhou University team to do it together.

Someone immediately said, "No, right?" ”

"I heard that Xijing's team disbanded after finishing its work, and it was empty, as if it was all out to play."

A few people next to him were a little envious when they heard this.

They're busy here, and they're so busy that someone else's team has gone out to have a good time.

"What about Wang Hao?" Tian Guilin asked in particular.

"I should be gone, too."

The person who spoke just now continued, "Because they handed in the report quickly, I paid special attention. I haven't seen Professor Wang for the past two days, and there are only a few people in their office area, and sometimes, only Xue Wenzhuo himself. ”

Tian Guilin pursed his lips vigorously and thought carefully.

He is an academician of high-energy physics, and in the research field of high-energy physics, he is naturally very authoritative, leading the seventh working group to do data analysis, and being surpassed by the 'subordinate' team, there should not be too many emotional fluctuations, but he can't calm down at all.

The speed and quality of data analysis completed by the two subordinate teams exceeded that of his working group.

Is this a capability gap for personnel?

Of course not.

Tian Guilin shook his head vigorously, simply stood up, and went to the office area of the Xijing Jiaotong University team.

When he arrived at the office area, he saw that it was empty, but there was still the sound of a TV.

At the door of an open office, Tian Guilin knocked on the door twice, "Knock, knock!" ”

Xue Wenzhuo was half-lying on the chair, supporting Erlang's legs and watching the video, he looked out, and said with surprise, "Academician Tian, why are you here?" ”

He immediately walked out, not forgetting to pause the video.

Tian Guilin smiled bitterly, "Professor Xue, you are really leisurely." ”

"Watching the TV show, the work is done, there is nothing to do, just wait for the final meeting." Xue Wenzhuo was also a little embarrassed.

Tian Guilin shook his head and said, "You guys can indeed take a leisurely moment. The analysis report made by you and Du Qisheng's team is really excellent, and our seventh working group is really completely overshadowed, so we should let you be the main force and we should be the substitutes. ”

"Hahaha~~"

Xue Wenzhuo immediately said, "We are here to learn, the people in the group, others don't understand, you are professional." ”

Tian Guilin glanced at Xue Wenzhuo with a strange expression, and he felt that the other party might be mocking him.

Coming to learn?

Don't understand anything?

As a result, the speed and mass of the particle characterization completely surpassed them?

Tian Guilin pursed the corners of his mouth vigorously, "I'll come this time, let's just say it, I want to know, how did you complete the analysis?" Don't get me wrong, because normally speaking, so much analysis can't be done in two or three days. He said and looked at Xue Wenzhuo seriously.

Xue Wenzhuo felt that there was nothing to say, so he said directly, "It's Professor Wang Hao, he designed a program that can directly do particle characterization analysis, and then we use the program to do the analysis." ”

Tian Guilin was stunned when he heard this, he looked at Xue Wenzhuo carefully, and asked seriously, "Do a program?" Analyzing particle properties? You're not kidding? ”

Xue Wenzhuo said a little incomprehensibly, "Academician Tian, what am I kidding, otherwise how can we finish it so quickly?" ”

"But ......"

Tian Guilin pulled a long tone, but still didn't say it.

A middle-aged man next to him helped to speak, "Particle properties can't be classified by program analysis. Ten years ago, when I started to study Cosi hyperons, I had already tried to design this method, and those algorithm experts said that it could not be done, otherwise there would be no need for so many experimental teams to participate in the classification of particle properties. ”

The others who followed also said, "yes, if a program can solve it, who is going to calculate it manually?" ”

"It's impossible. Such a complex analysis, which computer program can do. ”

"Also, there are some complex equation solving problems."

“……”

A few people said and said, making Xue Wenzhuo feel that he was about to be convinced.

He held back for a long time and said, "You all said it was impossible, just come and see!" ”

"Let's go!"

"This way!"

Xue Wenzhuo led the way in front, and did not add angrily, "But, look at it, when you see the effect, don't hit us with the idea of this program, you have to ask Professor Wang Hao." ”
