Research starts with PhD students

Chapter 6 Maybe this is the wrong decision?

Chapter 6 Maybe this is the wrong decision?
Luo Yongjun came to the central office building of the experimental base with the report.

The center's office building is the office location of the Institute of High Energy Physics' resident working group. The experimental review group is composed of the working group and influential scholars from several universities.

The office of the Area B Data Review Group is on the first floor.

When Luo Yongjun was about to reach the office, he met Professor Tian Guilin from the Department of Physics of Tongzhi University.

Tian Guilin and Luo Yongjun met when they were assigning experimental tasks, and half of the work content of the two groups was repetitive.

When reviewing, compare the analysis results with each other.

This will ensure that no problems occur and greatly reduce the difficulty of auditing.

With the same work content, there is competition among them.

Tian Guilin is an old professor in his fifties. He also has a competitive spirit and hopes that his group will perform better than other groups.

However, Tian Guilin didn't take Luo Yongjun seriously at all, because Luo Yongjun was just an ordinary scholar in the field of PDE.

There are a lot of such scholars.

It can be described this way: pick any two mathematics professors, and one of them will definitely focus on PDE as his main research direction.

Luo Yongjun is far from being outstanding. He is in his forties and is only doing general projects. It is hopeless for him to apply for the Young Elite Scientist Award. His personal level can be inferred.

In addition, Luo Yongjun only supervises two doctoral students, who are very young and have just enrolled. It is very likely that he completed all the work in their group by himself.

Although the other party was not very competitive, Tian Guilin still waved and greeted him, and asked in confusion, "Professor Luo, why are you here?"

When Luo Yongjun saw Tian Guilin, his eyes lit up immediately. He stood in front of the data group office in Area B and said loudly, "Submit the report!"

"Submit a report? What report?"

Tian Guilin didn't react for a moment.

Luo Yongjun smiled and continued loudly, "Of course it's the experimental data report. Our group has already finished it."

"impossible!"

Tian Guilin's voice was firm and resolute.

Luo Yongjun didn't care. Instead, he patted the documents he was carrying with his hand and said with a smile, "I won't say any more to you. Director Liu Ye is here, right? I'll go in first."

The door opened from the inside.

A middle-aged man with a square face looked outside, then walked out and asked, "Is it... Professor Luo? I heard it from inside. Has your group finished?"

Luo Yongjun nodded with a smile on his face and handed over the document in his hand, "Director Liu, this is our group's report."

"Are you really done?"

Liu Ye was very surprised, and then he praised, "I remember that the data given to your group was no less than that of other groups, and you were able to complete it so quickly... Professor Luo, your group is really good."

"Thank you, thank you!"

Luo Yongjun's face was almost smiling.

He glanced at Tian Guilin sharply.

When the work tasks were being divided, he disliked this old guy. The other party always acted condescending, as if he was looking down on an ordinary professor like him.

it's good now!

"My group is just faster than yours!" Luo Yongjun thought happily, and no longer paid attention to Tian Guilin. Instead, he talked to Liu Ye about applying for the experimental simulation program.

Liu Ye was immediately surprised. "A doctoral student in your group wants to conduct a study on the overall analysis of experimental data?"

"Correct."

Luo Yongjun nodded.

Tian Guilin couldn't help but ask, "Isn't this a bit too much? A doctoral student analyzing experimental data? And also using an experimental simulation program? Are you kidding?"

"How can I joke about such a thing?" Luo Yongjun said with a glare.

"but……"

Before Tian Guilin could say anything, Liu Ye asked, "What exactly is it? Why is it related to the simulation program?"

"Deviation analysis!"

Luo Yongjun introduced it in one sentence: "Study the deviation between real experiments and simulations."

"The deviation between the experiment and the simulation..."

Liu Ye tried to understand. He and Tian Guilin looked at each other and frowned at the same time.

He shook his head and asked, "Professor Luo, can you be more specific? How do you analyze the deviation between the experiment and the simulation?"

"Uh~~~"

Luo Yongjun scratched his head vigorously.

All he knew was what Zhang Shuo introduced. He didn't understand how to analyze or the logic of the main algorithm, but he didn't understand the specific content.

As a doctoral supervisor, isn't it a bit embarrassing to say that you don't understand anything about the research done by your doctoral students?

Especially, Old Man Tian is still here!

He gritted his teeth, exerted force, and pulled out a few strands of hair.

Got it!

"The deviation between the experiment and the simulation is the difference between the actual data and the ideal data. When using a core algorithm to calculate, the amount of computation involved will be very large."

"I will come here to apply for the simulation program first. After submitting the report for review, I may design and improve the program. The calculations will also use large computers..."

"In short, the research is very interesting. You will know the details when you make a report at the experimental conference!"

Luo Yongjun finished speaking in one breath.

Liu Ye was stunned for a moment, then shook his head and said, "Okay. It's just a simulation program, far from being confidential. I'll talk to Professor Liao and you can just go get it from him."

There are many experimental simulation programs for particle collisions, and some simple animated graphics can be found on the Internet.

However, the simulation program for each experiment is different. The difference is not in the main program, but in the input data, including differences in particle beams, energy level values, and so on.

Different particle beams and different energy intensities will naturally produce different effects on the impact.

Luo Yongjun got the reply and left.

Liu Ye turned around and asked Xiang Tian Guilin, "Professor Luo introduced a lot of things, but why do I feel like he didn't say anything?"

"He didn't say anything in the first place! What he just said was all nonsense."

"You don't have to keep your research secret like this..."

Tian Guilin complained vigorously, but he didn't think about the situation that Luo Yongjun didn't know. He shook his head and returned to the topic of the report. "He submitted the report so early. Is he really finished? Director Liu, you have to review it carefully."

Liu Ye said, "Professor Tian, half of the data in your group is repeated with that in Professor Luo's group, right? Then you should hurry up, and we will know when the time comes by comparing them."

Tian Guilin could only nod dejectedly.

What he meant just now was that he hoped the audit team would directly review Luo Yongjun's report and then find out the problems.

Liu Ye didn't want to do any extra work and just followed the regular review process.

After the data analysis report is submitted, it is not directly reviewed by the review team, but it will be compared with other groups. If the results are not too deviant and there is no problem with the comparison, it will be considered passed.

The audit team will only conduct a serious review if the results are inconsistent or the deviation is too large.

Reviewing and verifying every piece of data is of course a very tedious task.

Tian Guilin felt depressed when he thought of Luo Yongjun's expression. He left the center building and quickly walked back to the office. He found several doctoral students chatting and immediately shouted, "Get to work!"

“We need to work harder today and try to finish it in one day!”

He finished explaining, “I’m not urging you, I just have no choice!”

"I have some news for you. Luo Yongjun's team, which has duplicate data with us, has already submitted a report. There are only three people in their team, including Luo Yongjun, and we have five in total!"

"If we don't hurry up, we'll be laughed at!"

Several doctoral students wailed.

Someone immediately couldn't help asking, "How come they are so fast? They've handed in the report now? Is the level so high?"

"What do you mean by high level?" Tian Guilin immediately refuted loudly, "There must be something wrong! Once we finish the work, we will know after comparing the results!"

……

Luo Yongjun returned to the office, handed the simulation program to Zhang Shuo, and then couldn't wait to ask about the research content.

He doesn't want to be able to only give a rough idea of the direction the next time he is asked. Understanding the entire content of the student's research is the correct attitude of a doctoral supervisor.

Zhang Shuo gave a detailed introduction, "Using algorithms and evaluation systems, we can conduct deviation analysis in experiments and simulations."

"The algorithm for connecting the central anchor points to cover the data is just an introduction. The purpose is to reduce the amount of calculation as much as possible. The deviation assessment system is the key."

“Much of my research has been focused on improving bias assessment systems.”

"Fortunately, the scale of this experiment is not large, and the deviation assessment used is not that complicated. We can list them one by one..."

Luo Yongjun understood.

He thought about it for a long time, and his expression suddenly became a little exaggerated, "Can you really do it?"

"what?"

"I mean, your research...it sounds like this evaluation system is difficult!"

“It is indeed difficult.”

Zhang Shuo nodded and said, "We need to make dozens of algorithm packages, reduce the detection bias through continuous calculations, and then conduct evaluation."

"But I already have an idea."

"Ok."

Luo Yongjun took a deep breath and felt that he should still believe in his students. Zhang Shuo’s performance was extraordinary. Maybe he could really do it?

"If this research can really be done, let alone what will happen in the future, I feel that it will be no problem for the Institute of High Energy Physics to provide the funding!"

"Can this still happen?"

"of course."

Luo Yongjun smiled and said, "This is experimental research, which is directly related to experiments. We analyze experimental data, and we need to complete a lot of code to make a real program."

"If the Institute of High Energy Physics is interested, they will of course provide funding..."

"By the time……"

He chuckled and made a gesture as if he was counting money.

Zhang Shuo was also moved.

I had no pressure in life in my previous life. Firstly, my family was well-off, and secondly, I got a high-paying job after graduating with a Ph.D. The only thing I cared about was money. It was to raise funds for large-scale experiments.

That involves a huge amount of money of tens or hundreds of millions.

This life is different.

He comes from a very ordinary family. He has been financially independent since he started his graduate studies, but he still has to consider living expenses.

The treatment of doctoral students at Soochow University is not bad. The minimum basic standard for a single doctoral student is 36000 yuan per year, and the state subsidy is 15000 yuan, so the basic income is 51000 yuan. Doctoral students can also receive various scholarships. Not counting the allowance from the doctoral supervisor, they can get more than yuan a year.

Unlike other doctoral students, his master's degree was revoked.

Soochow University decided to let him continue his doctoral studies, but the department head Wu Qiao had a serious talk with him and made it clear that he could not receive any bonuses during his doctoral studies.

"If you get the bonus, those students who didn't get the bonus might be dissatisfied. If that gets into the public eye, it will be a problem for both the school and you."

"This is also a protection for the school and for you..."

Zhang Shuo could understand it after thinking about it.

Even without a scholarship, even if there is a public opinion problem, there will be an explanation to the outside world!
For the school, paying less bonus to a doctoral student is not a problem at all, but for him personally, it will make life a little difficult.

There are many grants available for PhD students.

For example, the tuition scholarship of the third level can cover all tuition fees. Without this scholarship, it will cost an extra 10,000 yuan each year.

Tuition, accommodation fees, plus other miscellaneous expenses, cost more than 20,000 yuan a year.

"Fifty thousand a year, and expenses are over twenty thousand."

"The monthly living expenses are only over 2,000 yuan, and there are other expenses..."

In short, it's very embarrassing.

Zhang Shuo pursed his lips as he thought about it, and smiled at Luo Yongjun, "If we can really get funding, Mr. Luo, you must help us get more."

"no problem!"

Luo Yongjun patted his chest vigorously and said, "Leave it to me!"

"I'm an expert in this area!"

"Last time, for a small project, the school allocated 30,000 yuan. I went directly to talk to the dean, and he later gave me an extra 10,000 yuan!"

"It's a small project, and it's worth 40,000!"

Luo Yongjun happily talked about his glorious history of asking for funding.

"Uh~~"
