Research starts with PhD students

Chapter 123: Doing the experiment in reverse? The theory you are studying?
The news that the Second Academy of Aerospace invited Zhang Shuo to give a lecture and paid him 60 yuan in lecture fees spread.

Many faculty and staff in the university are talking about this.

60 million.

This number is shocking!

It is normal for scholars to go out and give lectures.

Some professors with a certain degree of fame will often receive invitations to give lectures, including giving lectures to students in middle schools, giving lectures at other universities, and being invited to other units to explain their research results.

Zhang Shuo's situation belongs to the latter.

The cost for scholars to give lectures outside is generally only a few thousand yuan, some even only a few hundred yuan, and some even tens of thousands of yuan.

Scholars whose lecture fees can exceed ten thousand yuan are all academic leaders in their respective fields.

Some famous scholars sometimes receive tens of thousands of dollars in lecture fees, which is already a very high-end level.

In the School of Mathematics of Soochow University, only Tan Youming had received tens of thousands of yuan in lecture fees, and that was because he had the title of academician.

It is not easy for other professors to get a chance to give lectures. Many of them are only invited by middle schools to give speeches to encourage students to study hard.

In terms of personal research, it is too difficult to give lectures.

The lecture fee is as high as 60, which I have never heard of.

In addition, the inviting unit was the Second Academy of Aerospace Science and Technology.

The Second Academy of Aerospace Science and Technology is a large scientific research institution with a large number of professional scientific research talents. From academicians to doctoral students, there are hundreds of scholars with senior titles, and those engaged in administration all have a master's degree.

It is an honor in itself to be invited to give a lecture by such a scientific research institution.

The other party is also willing to pay 60 for the lecture!

This incident sounded incredible, and everyone else was envious and jealous.

Honor plus money!
Who doesn’t want to!

……

Not only Soochow University and the Second Academy of Aerospace Science and Technology knew that Zhang Shuo was invited to give a lecture, but some well-informed departments also knew about it.

For example, the Aerodynamics Technology Research Institute of the Aviation Group.

The Institute of Aerodynamics Technology is responsible for technical experimental research related to aircraft and aircraft engine aerodynamics.

They have been looking to upgrade their aerodynamic simulation system.

If aerodynamic simulation can be made more accurate, aircraft design will be more scientific and improve safety performance.

In this field, the requirements for fighter jets are the highest.

Fighter jets have to adapt to various harsh environments and perform supersonic flights, which require various high-pressure tests, so aerodynamic calculations must be more precise.

Faced with such demands, aerodynamic calculation and simulation is naturally very important.

The Institute of Aerodynamics Technology did not know that Zhang Shuo had published two other papers. They only saw the "NS Equation Computational Simulation". The related research can replace the DNS method, provide more accurate and stable predictions, reduce the amount of calculation to a certain extent, and help improve the high-pressure simulation system.

They also want to invite Zhang Shuo to give a lecture.

"During the previous meeting, we invited Professor Zhang Shuo to visit the institute."

In the office, Huang Junwei smiled bitterly and said, "Actually, I just want him to talk about his research so that we can understand it more deeply and see if it can be used."

"An invitation to visit is definitely not an option. Isn't that just saying you want to get free research?"

Qin Haifan said in annoyance, "I don't know what the Second Hospital is thinking. Six hundred thousand for a lecture? What should we do?"

"It's to drive up the lecture fees!"

"We had already planned to invite Professor Zhang Shuo to come, how can we bring this up now?"

Both of them were talking to Zhao Pengcheng.

Zhao Pengcheng is the leader of the institute and is responsible for related affairs. He thought for a moment and said, "The Second Institute has paid such a high lecture fee. We really can't invite them in the name of a visit."

He shook his head and said, "Lecture fees are not a problem, but 600,000 is impossible!"

"Even if I agree, my superiors won't approve it."

Zhao Pengcheng was also very depressed as he spoke, his voice full of doubt, "Is the aerospace department so rich?"

"Six hundred thousand!"

"What kind of lecture is worth 60? This is the funding for a big project."

The three of them discussed it and finally decided to wait.

It’s not too late to invite Zhang Shuo again after he comes back from his lecture at the Second Hospital. At the same time, if one of them was invited to give a lecture for 60 yuan, the other would not be able to ask for anything at all.

Zhang Shuo must be making a comparison in his mind.

Colleagues will also have something to say.

……

The Research Institute Building of Soo Dong University.

Zhang Shuo's office.

Luo Yongjun found Zhang Shuo with the printed materials. He put the materials on the table, operated the computer to download the email content, and then began to explain it carefully.

He went to see Zhang Shuo to see the results of his analysis of the experimental data from the Quantum Research Institute.

This is the problem encountered by the Quantum Institute.

After Zhang Shuo guided the direction of data analysis, Luo Yongjun has been doing the analysis. After completing the analysis, he still felt a little lacking in confidence, so he came here to talk about it specifically.

Zhang Shuo listened patiently, and the progress of the task continued to rise.

[Task 0.533, progress +%. ]

[Task 0.483, progress +%. ]

[Task 0.20, progress +...]

Luo Yongjun spoke for more than half an hour, from the judgment of the overall data to the detailed analysis methods and then to the analysis results.

After listening to all the explanations, the 'Task 1' prompt is completed.

Zhang Shuo looked at Luo Yongjun with a gratified expression and exclaimed, "Teacher Luo, your analysis is really good. I can't do better than you!"

Luo Yongjun was so pleased with the compliment that he quickly waved his hands, "No, no, I can't compare to you!"

Having said that, he couldn't hide his smug expression.

Sun Xingli strolled in, pushed the door open, and saw the two people talking about research issues, so he simply sat on the sofa and listened.

Zhang Shuo submitted the task.

The research was all completed by Luo Yongjun, and the mission rewards were very small.

【Scientific research coin +1.】

“It paid off!”

When establishing the task, Zhang Shuo spent some scientific research coins to find the direction, and after completing the research, he got his "principal" back.

At the same time, there are other gains.

Completing the task will help him gain a deeper understanding of the research itself, and immediately find some minor problems in the analysis.

That won't affect the overall results, but the data analysis in some places is slightly biased.

Zhang Shuo found a few pages from the information and explained them one by one. "There is no problem with the overall analysis, but some details can be improved. For example, here..."

Luo Yongjun looked over.

Zhang Shuo explained, "This position can be calculated using another method..." "We can study it in different areas, and then..."

"And this place..."

He mentioned several locations in succession.

Luo Yongjun listened patiently. He didn't think anything at first, but later he found something was wrong.

Zhang Shuo just said that he couldn't do any better?

"So they were all trying to comfort me?"

"I'm so happy!"

Luo Yongjun shook his head depressedly, picked up the documents and went out with a strange mood.

Sun Xingli quickly caught up with him and walked out of the research institute building with him. He could no longer hold back and teased, "Lao Luo, your report to Teacher Zhang just now went very smoothly. Congratulations."

"Teacher Zhang just praised you, that's great!"

Sun Xingli patted Luo Yongjun on the shoulder and said, "Come on! There should be no problem this time. You can hand in the homework after some revisions!"

After he said that, he ran away.

Luo Yongjun didn't react for a moment. He stood there in a daze for a moment. When he came to his senses, he kicked out with a big kick, but was dodged.

He stamped his feet in anger and cursed, "Grandson! Don't run!"

"I'm not going to beat you up!"

Luo Yongjun simply took off his shoes and threw them over, then gasped heavily on the spot. Thinking about it carefully, he felt even more depressed.

mainly……

Sun Xingli’s description is so damn similar!
……

Near the end of the month.

Zhang Shuo devoted himself to the preparatory work for the CP group's experiments.

At the same time, I also received some invitations.

For example, Qiu Chengwen invited him to visit the School of Mathematical Sciences at Shuimu University.

Zhang Shuo thought about it and finally agreed. He was going to the capital anyway, so it wouldn't hurt to visit Shuimu University.

In this way, the itinerary in the capital includes the CP group of the Institute of High Energy Physics, the headquarters of the Second Academy of Aerospace Science and Technology, and Mizuki University.

Zhang Shuo suddenly found himself becoming very busy and thought that he should have an assistant. It would be much easier if he had an assistant to help with itinerary arrangements, carry things, take care of daily life, etc.

In the end, he went alone.

After getting off the plane at the Capital Airport, he got on the car sent by the Institute of High Energy Physics to pick him up, and then headed straight to his first destination -

Particle collision experimental base.

This was my third visit to the particle collision experiment base, and the reception I received was also the most grand.

Yu Fei and Zhu Wang from the CP group, Liu Ye, Cao Jiankun and others from the basic experiment group were already waiting at the door.

Among them is Wu Jianning, director of the Institute of High Energy Physics.

Wu Jianning was at the experimental base and came over to greet Zhang Shuo, also to show his importance to his arrival.

Yu Fei helped to introduce it.

Zhang Shuo was also surprised when he shook hands with Wu Jianning. "Hello, Academician Wu. I am flattered that you came to greet me in person!"

"Professor Zhang, you are an important person!"

The two exchanged pleasantries.

Wu Jianning really attaches great importance to Zhang Shuo. Their most important project is the large-scale experimental deviation analysis algorithm, and the algorithm ideas and framework of the algorithm project of the Computing Center were completed by Zhang Shuo.

In the field of high-energy physics, Zhang Shuo's influence is already very great.

High-energy physics institutions abroad are all researching related algorithms, hoping to complete deviation analysis for large-scale experiments.

Wu Jianning was even more curious about Zhang Shuo's decision to join the CP group.

The research of Zhang Shuo and Agostini disproved the signal conversion method in hyperon decay experiments and proved that the baryon CP violation signal would be hidden in other signals.

Such research negates the value of many of the CP group's results.

The reason why the CP group has fallen to such a state is directly related to the research of Zhang Shuo and Agostini.

Tan Zhiming resigned from the position of head of the CP group, but Zhang Shuo agreed to join and even prepared a new experimental direction?

Wu Jianning felt that he was getting old and could no longer understand anything.

New experimental direction?

Can it work?
Others also held skeptical attitudes. When it came to analyzing experimental data, Zhang Shuo was very authoritative.

Experimental data analysis is the follow-up work of basic experiments.

Joining the CP group now is completely different. It means directly participating in experimental work and even designing experiments to verify new research directions.

There is a huge difference between the two.

Wu Jianning and his team accompanied Zhang Shuo into the experimental base.

The CP group's research is an extension of particle collision experiments, and their spectrometer detection equipment is directly connected to the particle collider.

Zhang Shuo came to the experimental base to visit the spectrometer detection equipment for studying hyperon decay. He talked to Wu Jianning along the way, "I decided to join the CP group because I want to conduct research in a new direction."

Wu Jianning asked in confusion, "I heard from Yu Fei that it was strong electromagnetic interference hyperon decay. There has never been such an experiment in the world."

"The CP violation experiment is to minimize the magnetic field that affects the movement of hyperons."

"Do the experiment in reverse..."

Zhang Shuo said, "The new direction I mentioned can be related to the unknown physical phenomena in particle collision experiments, and at the same time, it can also be related to the study of baryon CP violation."

"I said there is a connection between the two because the content of the baryon CP violation signal in the standard model of particles is incomplete."

"The description of CP violation in the standard model of particles cannot explain the composition of positive matter in the universe."

"In this case, we cannot determine the form of the baryon CP violation signal, and the previous studies were based on the assumption that the baryon CP violation signal and the meson CP violation have the same form, that is, there is a spin difference between the positive and negative particles."

"The existence of baryon CP violation is not certain."

Wu Jianning listened and nodded. This problem does exist in the research on CP destruction signals.

After the discovery of the CP violation signal of mesons, the field of high-energy physics believed that the baryon CP violation signal also existed in a similar form, which led to the research on baryon CP violation.

If CP violation existed in a different form, experiments related to hyperon decay would not be able to make discoveries.

Wu Jianning was silent for a moment, then asked, "Does your new research have any theoretical support?"

Zhang Shuo said, "In this experimental direction, I have studied some theoretical content and will give a report at the Physics Center meeting in a few days."

Wu Jianning was stunned. "What theory are you studying?"

Zhang Shuo nodded calmly, "Including unknown physical phenomena in particle collision experiments, as well as new experimental directions, I have some unpublished theoretical results."

He changed his tone and said, "Director Wu, high-energy physics experimental research should not be for verifying perfected theories, or just imitating the experiments of other scientific research institutions and publishing some papers or results reports, right?"

"Of course." Wu Jianning nodded.

"My understanding is that high-energy physics experiments are designed to explore the fundamental mysteries of particle physics, study the deep laws governing the operation of the universe, and explain some phenomena that cannot be explained."

“That’s really the main goal of the research.”

Wu Jianjun was silent for a long time, then he sighed with mixed feelings, "Then we are looking forward to your report!"
