Chapter 138 The team completes the work efficiently, program analysis? Tian Yuan
Scholar: This is impossible!
The Xijing Jiaotong University team works in several offices on the left side of the third floor of an office building.
Nearby is the Huzhou University team.
Xue Wenzhuo went to look at the Huzhou University team. They were all doing data analysis in Area F. Their work content was very similar, and the comparison and discussion were also very meaningful.
After returning to the office, he saw a submitted data file displayed on his computer.
"Data analysis summary file? He Yi sent it?" Xue Wenzhuo took a look at the content and was immediately surprised.
The experiment was just completed yesterday, and the work was assigned yesterday afternoon. It has only been a full day. How come the data analysis summary file has already been submitted?
Xue Wenzhuo simply opened the door and walked out to the small office where He Yi, Wang Hao and the other four people were. He opened the door and took a look, only to find that it was empty and there was no one there.
"Where are the people?"
Xue Wenzhuo muttered something strange, then came back to continue reading the data file submitted by He Yi.
He took a quick glance and knew that all the data of He Yi and Wang Hao's teams were already in it.
"It's impossible~~"
"How could it be so fast?" Xue Wenzhuo was very puzzled. He found the original document and tried to verify the two data in the report file. The results were all correct.
He simply walked out of the room and shouted, "Professor Dong! Xiao Zhang! Come over and help take a look at this."
‘Xiao Zhang’’s name is Zhang Lijun, and he is a doctoral student under Xue Wenzhuo.
Professor Dong is Dong Zhihui.
After the two came over, they were also very surprised when they heard Xue Wenzhuo talking about He Yi's team and that it had completed the data analysis work.
Dong Zhihui even said, "It's not just made up, right?"
"Isn't this impossible?" Xue Wenzhuo said, "I just measured two data manually, and the results are both correct. Let's test it together and see if there are any problems."
The three people immediately began to manually verify.
He Yi's team is responsible for analyzing the particle characteristics of ordinary light points. To put it simply, it analyzes what particles each small light point is, and then adds other measured data of the small light points to it.
The most important of these is to verify the particle properties.
Three people randomly selected some raw data and then performed manual calculations for each one.
Twenty minutes later, Dong Zhihui said with surprise, "There is no problem with the data I drew just now. Only one of them is wrong. It is a very difficult calculation and the error rate is very low."
Zhang Lijun buried his head in calculations and said, "It's the same here, I haven't found any erroneous data yet."
Xue Wenzhuo simply stopped writing. Like Zhang Lijun, he found no errors, which showed that the quality of this particle characteristic analysis data was still very high.
Particle characteristic analysis work has a certain error tolerance.
Generally, if the error rate is below 1%, it is considered qualified, and if the error rate is around 0.5%, it is already excellent.
Judging from the data extracted now, the error rate of this particle characteristic analysis data is likely to be less than 0.5%.
Xue Wenzhuo felt a little incredible, "How did they complete it? Completed it in one day? So fast? Even with Professor Wang Hao, it couldn't be possible, right?"
Dong Zhihui and Zhang Lijun couldn't understand either.
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 can directly obtain the results of complex calculations, it is impossible to complete all the particle characteristic analysis work in such a short period of time.
"Ask them!" Dong Zhihui turned around and went to the small office of the foursome.
Xue Wenzhuo reminded, "There is no one in the office, they have all gone out."
Dong Zhihui thought for a moment and immediately took out his mobile phone, "I'm going to make a call. I have He Yi's number and ask them what they are doing and come back soon."
When he was about to make a call, Zhang Lijun suddenly said, "They are going to have a big dinner."
"ah?"
Xue Wenzhuo and Dong Zhihui looked over together.
Zhang Lijun showed them the screen of his mobile phone, which displayed information about his circle of friends.
Deng Xiaoying made a video and posted it on WeChat Moments. The content of the video was a large table of dishes and a grilled fish that looked delicious. You could smell the aroma through the screen.
There are also He Yi, Wang Hao and Xiao Xinyu in the picture. They are eating grilled fish and drinking beer. They look very happy.
After watching the entire video, Xue Wenzhuo felt his stomach growl and said with some embarrassment, "I haven't eaten a few bites of the lunch box, is it almost time for lunch?"
"The food was just delivered and I lost my appetite. After watching this video, I lost my appetite even more."
"Me too, I also have no appetite..."
The three of them looked at each other with sad expressions.
…
It was not until seven o'clock in the evening that Xue Wenzhuo finally saw He Yi, Wang Hao and others return.
He walked over full of sorrow and asked, "How did your group finish it so quickly?"
"We came back in a hurry just to talk about this..." Deng Xiaoying burped as she spoke, showing no signs of being anxious at all.
Xue Wenzhuo's expression became even sadder. Are you in a hurry to come back?
So full?
Deng Xiaoying continued nonchalantly, "Professor Wang Hao designed a program that can analyze the characteristics of particles, so we completed it quickly."
Xue Wenzhuo immediately realized, "Is there such a procedure?" He said and looked at Wang Hao.
Wang Hao nodded lightly and said, "That's why we came back, or we would have just returned to the hotel. It would be great if you also use this program for analysis. You can directly classify the particles and then fill in the data."
"That's great." Xue Wenzhuo was immediately pleasantly surprised. Because he had already tested the data, he had no doubt about the effectiveness of the program.
This is definitely a program that can greatly improve efficiency and reduce workload.
Xue Wenzhuo followed Wang Hao to the computer and copied the source code. While test-running it, he sighed, "Professor Wang, you really gave us a big surprise. This program is so important."
"If all the data can be analyzed by programs and the results can be obtained, we can complete all the work tomorrow and the day after tomorrow."
After Xue Wenzhuo ran the program, he used all the data as input and then performed the output in one operation. He quickly found an efficient way to use a computer to do the calculations, and then let one person operate the specified files and transfer them separately.
Give it to others and continue with the next step of data filling.
When the time came the next morning, everyone in the team knew the news. They did not need to further divide the particle characteristics, they only needed to fill in the data and calculate. The work was relatively simple.
Everyone is full of energy and continues to work hard together.
He Yi, Wang Hao and others re-involved to share some of the work with the team so that the work can be completed faster.
By noon on the third day, all data analysis work had been completed.
Xue Wenzhuo also summarized the data. After doing a series of analyses, he stretched and took a breath and submitted the content with a smile on his face.
Then he walked out of the office and announced, "Our job is done!"
"Everyone can go around if you are in the mood. The capital is still worth visiting. The Great Wall, the Forbidden City, and the Summer Palace are all there. You can't come here in vain."
"Yeah~~!!"
Everyone cheered excitedly.
They came to participate in the data analysis of the particle collision experiment, but they did not expect to go around and have fun, because the data analysis work was very heavy, and they were mentally prepared.
As a result, work has ended early, and the extra few days have become vacations, which is really happy.
…
The speed with which Xijing Jiaotong University completes its work is very surprising.
The data in Area F cannot be said to be complicated, but the analysis work is definitely not simple. Normally, it would take at least five days for a team of less than twenty people to analyze half of the data in a single area.
This is still very fast.
The Xijing Jiaotong University team is a mixed team. Many people are participating in similar work for the first time and have no experience at all. The speed of analysis is naturally much slower. Under normal circumstances, it takes a week to complete.
As a result, on the afternoon of the third day, the Xijing Jiaotong University team submitted the data summary report.
The report is submitted to the Experimental Review Committee.
This committee was temporarily formed and includes academicians and professors from the Institute of High Energy, resident experts from the spectrometer experimental team, and scholars from institutions participating in international cooperation.
Tian Guilin is also one of them.
Tian Guilin is responsible for leading the seventh working group and is also a member of the Experimental Review Committee.
After the Xijing Jiaotong University team submitted the data report, he quickly learned the news and was very surprised. "Why is the Xijing Jiaotong University team so fast?"
"It's been less than three days. Isn't this speed abnormal?"
Tian Guilin frowned and was puzzled.
A professor from Capital University next to him said, "Could it be Wang Hao? Wang Hao's mathematics level is top-notch. He can play a big role in this kind of work."
"impossible."
Tian Guilin immediately denied, "In this kind of complex analysis work, one person's role is limited. No matter how fast he does calculations, the calculations are only second. At most, he is just a little faster than others."
Tian Guilin said he couldn't think of the reason, so he simply said, "Let's first finish the part of the data that the Xijing Jiaotong University team is responsible for, and compare it with their data."
"There may be problems with the data analysis completed so quickly..."
Tian Guilin thought about it and continued, "It is not enough to pursue speed alone, but also to pursue stability and accuracy. The Xijing Jiaotong University team has little experience. This time we will teach them a lesson and tell them that in data analysis, accurate results are more important.
"
…
Other experts on the Experimental Review Committee, including Hetian Guilin, had the same judgment. They were surprised that Xijing Jiaotong University quickly submitted the data analysis report.
At the same time, they believe that fast speed does not mean anything, what is important is the accuracy of analysis.
The Xijing Jiaotong University team is just a "second subordinate team". It may be for the reason of "fighting for breath" and wants to complete the work quickly, but it is very difficult to ensure accuracy.
Of course.
The Experimental Review Committee cannot make judgments based on imagination, they still conduct random inspections.
This test method is the same as Xue Wenzhuo's, which is to randomly select a part of the data for calculation.
Because the seventh working group was the 'home team', there were only two people doing the calculations at first. Later, they found that most of them were correct, so they found more people to check.
After two hours of testing, everyone was shocked by the results——
"Particle characteristic classification, the error rate is less than 0.2%!"
This error rate is quite alarming.
In fact, it is the same as solving difficult problems. No one can guarantee that every question can be answered correctly. In addition, some questions are very vague, some particle properties are very similar, and the captured information will be affected by other influences, so there is no way to completely solve the problem.
Determining what particle it is, that is, there is no precise answer.
Because of this, particle characteristic analysis has a certain error tolerance rate, and all errors below 1% are qualified.
Generally, the error rate of data submitted by a regular working group is between 0.5% and 0.8%, as long as it meets the error expectations.
0.2% is an unimaginable number. It can be said that except for some controversial data, everything else is correct, which is equivalent to a perfect score.
There is no confidentiality in the initial analysis of particle characteristics in the experiment. It is just the initial data analysis. To put it simply, it is to classify the experimental data to lay the foundation for the next step of analysis.
Soon many people knew the news.
Tian Guilin also learned the news immediately. He felt a little incomprehensible and also felt very stressed.
The seventh working group is also a temporary team, but they have several experts from the Institute of High Energy. There are also several people in the team who have been engaged in related work for a long time. Others are also professors from Capital University. They formed a working team together to do data analysis.
The speed and quality cannot keep up with the 'subordinate' Xijing Jiaotong University team?
Several people in the Seventh Working Group found it unacceptable after hearing the news.
They also analyzed the reason together, "Although I don't know what happened, I feel that this time it may be related to Professor Wang Hao of Xihai University."
Tian Guilin did not refute again this time.
The fast speed and high quality of experimental data analysis shows that there must be capable and expert people in the team.
Searching the Xijing Jiaotong University team from top to bottom, we can only attribute the reason to Wang Hao. He is an expert in theoretical mathematics. He has just completed the proof of the Kakutani conjecture and is recognized as a top mathematician.
A mathematician of this level might have some good ways to simplify things when doing mathematical analysis?
“Fortunately, there is Huzhou University!”
Tian Guilin sighed, "If the two subordinate teams are faster and higher quality than ours, our seventh working group will be meaningless."
"What a big shame this time!"
the other side.
Du Qisheng, the team leader of Huzhou University, found Xue Wenzhuo, and he also heard that Xijing Jiaotong University had completed the analysis work.
Du Qisheng felt very incredible.
Compared with Xijing Jiaotong University's team, the team from Huzhou University is still a little behind, but the difference is not too much, and the tasks assigned to them are similar.
The Huzhou University team has just completed one-third of the work, while the Xijing Jiaotong University team has already completed it.
This efficiency gap is also too big.
Xue Wenzhuo and Du Qisheng were very familiar with each other, so they mentioned that Wang Hao had developed a program that could be used to analyze particle characteristics. Finally, they called Wang Hao to see if he could help the Huzhou University team with the analysis.
.
Wang Haozheng was visiting the Forbidden City with He Yi and Xiao Xinyu, and he immediately agreed after receiving the call.
The program he designed was specifically for the analysis of particle characteristics, even if it was only for the data from this experiment, it had no commercial value and would have little meaning after the experiment.
If other teams want to use it, they can naturally use it too.
After the Huzhou University team used the program designed by Wang Hao to analyze particle characteristics, the speed of analysis immediately doubled. In less than a day, they completed all the remaining work and submitted the data immediately.
.
This is only the fifth day since the experimental analysis work began.
The Experiment Review Committee received the data submitted by the Huzhou University team and immediately conducted testing and analysis. It was found that the error rate was within 0.5%, which is also a very excellent particle characteristics analysis report.
The most important thing is that the Huzhou University team completed the analysis work very quickly.
Five days does not sound fast. In fact, because the scale of the experiment is slightly larger this time and more data are allocated, it will take more than a week for the professional working group to complete the analysis of particle characteristics in the last area.
The Huzhou University team is responsible for half of the data in a single district. Considering that they are just a 'subordinate' team and many people in the team have come here to study, it only took five days to complete the analysis of half of the data, and the error rate was still within 0.5%.
, the speed and quality are quite amazing.
Tian Guilin felt a little calm after receiving the news again.
With the precedent of the Xijing Jiaotong University team, the Huzhou University team was slightly faster, but it seemed nothing compared to it. He still asked, "Did Xijing help Huzhou University?"
He thought it was Xijing Jiaotong University, and after finishing the work at hand, he went to help the Huzhou University team.
Some professors immediately said, "Don't you have this?"
"I heard that the team in Xijing disbanded after finishing their work. It was completely empty inside, as if they all went out to play."
Several people nearby were a little envious when they heard this.
They were busy here, exhausted, and as a result, other people's teams had already gone out to have fun.
"Where is Wang Hao?" Tian Guilin asked specifically.
"She should be leaving too."
The person who just spoke continued, "Because they handed in the report very quickly, I paid special attention to it. I haven't seen Professor Wang in the past two days. There are only a few people in their office area. Sometimes, it's just Xue Wenzhuo himself."
Tian Guilin pursed his lips hard and thought carefully.
He is an academician of high energy physics. He is naturally very authoritative in the field of high energy physics research. He leads the seventh working group to do data analysis and is surpassed by the 'subordinate' team. He should not have much emotional fluctuations, but he does not have much emotion at all.
Can't calm down.
The speed and quality of data analysis completed by the two subordinate teams exceeded his working group.
Is this a capability gap among personnel?
of course not.
Tian Guilin shook his head vigorously, 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 the TV playing.
At the door of an open office, Tian Guilin knocked twice, "Boom, boom!"
Xue Wenzhuo was half lying on a chair, leaning on his legs and watching the video. He looked outside and said in surprise, "Academician Tian, why are you here?"
He walked out immediately, not forgetting to pause the video.
Tian Guilin smiled bitterly and said, "Professor Xue, you are really leisurely."
"Look at the TV show. After 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 can really take your time for a while. The analysis report you and Du Qisheng's team did is really outstanding. Our seventh working group is really overshadowed. You should be the main force. We
Be a substitute."
"Hahaha~~"
Xue Wenzhuo immediately said, "We are here to learn. Others in the group don't understand. You are the professionals."
Tian Guilin glanced at Xue Wenzhuo with a strange expression. He felt that the other party might be mocking him.
Come to study?
do not understand anything?
As a result, the particle characteristics analysis showed that the speed and mass completely exceeded them?
Tian Guilin pursed his lips hard, "I'm here this time. To be honest, I want to know how you completed the analysis? Don't get me wrong, because normally, such a lot of analysis work cannot take two or three days.
Done." 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 analyze particle characteristics, and then we used the program to do the analysis."
Tian Guilin was stunned after hearing this. He looked at Xue Wenzhuo carefully and asked seriously, "Make a program? Analyze particle characteristics? Are you kidding?"
Xue Wenzhuo said a little confused, "Academician Tian, are I kidding? How else could we complete it so quickly?"
"But……"
Tian Guilin made a long sound, but still didn't say anything.
A middle-aged man next to him helped and said, "Particle characteristics cannot be analyzed and classified by programs. Ten years ago, when I started studying Corsi superons, I had already tried to design this method, and the algorithm experts said it couldn't be done.
Otherwise, there would be no need for so many experimental teams to participate in the classification of particle properties."
Others who followed also said, "Yes, if a program can solve it, who would still use manual calculation?"
"This is impossible. Such a complex analysis cannot be done by a computer program."
"Moreover, there are some complex equation-solving problems in it."
"..."
Several people talked and talked, making Xue Wenzhuo feel that he was almost convinced.
He held it in for a long time and said, "You all say it's impossible, you'll find out if you come and see!"
"Walk!"
"This way!"
Xue Wenzhuo led the way and added angrily, "But, wait and see, after you see the effect, don't think twice about our program. You have to ask Professor Wang Hao."
