Research starts with PhD students

Chapter 4: Non-existent Bias Assessment System
Luo Yongjun was much more excited than Zhang Shuo, as if he had completed the great research himself.

No wonder he was so excited.

Mathematics, especially pure mathematics, is the most difficult subject, not even "one of the most difficult subjects".

Most mathematics PhD students have to delay graduation, and what holds them back is two words:
paper!

Every direction of pure mathematics is difficult, and PDE (partial differential equations) has become the most popular field.

This field has many directions, many applications, and a wide range, which means that there is a lot of content to be studied, but many PhDs are still stuck on dissertation issues.

Graduation thesis is just one of them.

Many universities require students to publish SCI papers during their doctoral studies. Soochow University has the same requirement, and doctoral graduates need to publish at least one SCI paper.

There are the most mathematicians in the field of PDE, and the largest number of professional academic papers, but it is still very difficult to publish excellent SCI papers.

Based on influence, SCI journals are divided into four zones. Zones 50 and have the greatest influence, while Zone is the dividing line of over %.

Most mathematics PhDs can only publish one or two SCI Zone 4 papers during their doctoral studies, or simply switch to mathematics and computer science and publish a paper.

If you want to publish a mathematics paper in SCI Zone 3, you need to have content and innovation.

This is a very difficult thing.

There are many scholars in the PDE field, and no matter which sub-direction it is, it can be said that it has been thoroughly studied. Most innovative research only expands on a small field.

For example, incompressible fluids.

A large number of scholars are engaged in the research of incompressible fluids, and countless papers can be found. If you want to have innovative research in related fields, you can only expand in a small direction.

The method of changing the PDE equation group developed by Zhang Shuo can be applied to equation groups with one PDE equation, and can even be expanded to two. The application fields involved are very wide. In other words, the research itself has a great application basis.

With an application foundation, the paper will receive many citations and have a high impact after publication.

This kind of mathematics paper with a wide coverage reaches the standard of SCI Zone 3 journal just by looking at the content.

If you try hard, your submission to a Zone 2 journal may be accepted.

A Zone 2 SCI paper in mathematics will be an important addition to a mathematics professor's resume, and will directly help with project applications and professional title promotion.

Not to mention, Zhang Shuo has only been a doctoral student for half a year.

"When you return to school, you should focus on writing your paper. If you have any questions about the content, English, and submission, please come to me."

"With this paper as a foundation, you can prepare your doctoral thesis with peace of mind..."

Luo Yongjun said a lot of things in succession.

Zhang Shuo pretended to listen attentively. He knew that Luo Yongjun was doing this for his own good, but he had never worried about the thesis issue.

……

The next day, Luo Yongjun, Zhang Shuo and Liu Chengjie came to the office early.

Luo Yongjun quickly entered working mode and began to write the data report seriously.

Their group has completed the computational analysis of the experimental data. All that remains is to make a small summary, list the key figures, and write a simple report.

“It’ll be done in an hour!”

Luo Yongjun decided to complete the work before the official working hours so that he could send the report to the review team as soon as possible. By then, others would know that their group completed the work in just one day.

Liu Chengjie had nothing to do.

He couldn't participate in the report writing work, so he simply found a movie to kill time, but he was obviously a little uneasy and couldn't help turning his head to look at Zhang Shuo.

He and Zhang Shuo are not familiar with each other.

After entering the doctoral program, they were not assigned to the same dormitory and only met once during classes and weekly discussions.

But when you are under the same mentor, you will always compare yourself with others.

Liu Chengjie always felt that he was better than Zhang Shuo. When he learned that Zhang Shuo's master's degree was revoked, he even looked down on him in his heart - a guy whose master's thesis was suspected of plagiarism probably just cheated his way through graduate school.

Even if the school did not expel Zhang Shuo and decided to let him continue his doctoral studies, it became very uncertain whether he could continue his studies and whether he could graduate.

Yesterday was a disruption.

Zhang Shuo demonstrated excellent computing ability and was able to quickly complete complex tasks with his tutor. Later, his tutor excitedly praised his achievements.

And they said that the highest submission is to SCI Zone 2?

"So, Donggang University said it was 'plagiarism' and revoked Zhang Shuo's master's degree. There must be something wrong, right?" "Zhang Shuo is so outstanding..."

"But why? I am also a newly enrolled doctoral student, and my grades have always been among the best in undergraduate and graduate studies. Is it possible that the teaching level of Donggang University is higher?"

Liu Chengjie couldn't figure it out.

Zhang Shuo didn’t think that way.

His mind was not on the report or the paper, but on checking the experimental data of Zone B in the computer.

The "Source Point Theory" was originally proposed based on the discovery of unexplainable phenomena - trajectory deviation and electromagnetic energy loss - during data analysis of large-scale particle collision experiments.

After a comprehensive and detailed study of the tiny particles after the collision, the research organization found that there was a deviation between the trajectory of the massive particles and the simulated trajectory.

Electromagnetic energy loss is calculated based on the electromagnetic radiation and residual energy caused by particle collisions.

The deviations between the two phenomena and the simulation situations are very small, and they can only be analyzed and detected by conducting super-large particle collision experiments and very precise calculations.

In addition, there are many explanations for the deviation.

The initial explanation was that external interference, even if it was just sound interference, could affect the test results.

Other explanations include 'miscalculation of mass and energy'.

The collision of particle beams will generate energy, and energy has the property of transfer. When comparing the initial and final results in the experiment, it is normal to have deviations in particle trajectories and energies.

The source point theory explains this as a connection between electromagnetic force and other forces.

This view was initially totally unacceptable.

Traditional physics believes that the four forces are the basic forces in the universe and have no connection with each other.

As the influence of the "Source Point Theory" expands, more people participate in the work of shaping the theory, and the Source Point Theory becomes more and more perfect and is accepted by more and more people.

The appeal of the origin point theory lies mainly in that it breaks through the physical bottleneck and creates unlimited possibilities for technological development.

Zhang Shuo came into contact with the source-point theory through his mentor Hu Jian, and later became deeply fascinated by the mathematical logic contained therein.

After conducting in-depth research, he became a firm believer in the source-point theory, and his scientific research goal was to improve and verify the theory.

What is being conducted now is a particle collision experiment, the goal of which is to measure the quantum state characteristics of the particles. This requires repeated experiments to accumulate to the point where quantitative changes lead to qualitative changes.

They were only participating in a small experiment in the research process, but no matter how small the scale of the experiment or how low the intensity, the basis is to conduct particle collisions and analyze and study microscopic physical phenomena through data monitoring.

"Large-scale particle collision experiments will experience trajectory deviation and electromagnetic energy loss. Small-scale particle collision experiments will definitely have the same phenomenon, but the signal is so weak that it cannot be detected."

"Perhaps even when the deviation is large, it can be measured? What means can be used?"

Zhang Shuo was thinking.

The deviation measurement of particle collision experiments in the past used a method called 'Lbnt analysis' to analyze the simulation deviation problem of collision phenomena.

The 'Lbnt analysis method' can not only be used to study particle collisions, but can also be used to study phenomena in the macroscopic world, such as explosions, impacts, volcanic eruptions, and so on.

"The 'Lbnt analysis method' is too complicated and it is impossible to develop it in a short time."

"The data scale of this experiment is not large. Perhaps we can find a comprehensive analysis method?"

"If we start from the data at the center and make anchor points for line analysis, the amount of calculation will only be several times more, but because the calculation is simple and the data scale is not large, it can be completed by using a supercomputer to run for a period of time."

Zhang Shuo thought about it and started writing down the analysis method.

After drawing a few algorithm frameworks, he suddenly thought of the scientific research support system and tried to establish a research task -
【Task 1】

[Research project name: Central anchor point connection analysis data simulation bias (difficulty assessment: C). ]

【Progress: 0.203%.】

(The task can be canceled. The current number of research coins required to cancel the task is 0.)
(The remaining progress requires 100 scientific research coins.)
【Scientific research currency: 1. 】

"C-level?"

"Is it that high?"

"The method of connecting the central anchor points is not difficult even for designing the main program. The difficulty should be... the deviation assessment system?"

"This world has no bias assessment system, so..."

"If I take the knowledge and use it, can it be considered as my own research?"
