Research starts with PhD students

Chapter 5 Sometimes lies can really help people!
"Using the knowledge from my previous life can also be considered my own achievement..."

"In other words, as long as I achieve a research breakthrough that does not exist in this world, even if it is plagiarized, it will be considered a breakthrough achieved by my own research?"

Zhang Shuo's eyes suddenly lit up.

Although it was just a task difficulty rating, he gained insight into the internal mechanism of the system.

First, the system is not cross-world.

The difficulty evaluation of scientific research tasks established in the system is related to the difficulty of research, but not to the "imagined difficulty" or "promoting effect on academic or technological development".

The central anchor point connection algorithm is not difficult for scientific research. It is just a method to simplify the amount of calculation.

The difficulty of the 'bias assessment system' associated with it can reach the C-level, but the most important thing is not the difficulty, but 'how to come up with it'.

For example, when Newton saw an apple fall to the ground, he thought that the ground had gravity, which promoted the development of basic mechanics.

If we use the system mechanism to give a difficulty rating to the initial thinking itself, perhaps it can only reach level D?
Because, 'thinking of' is not included in the difficulty coefficient.

In addition, some small studies can have a huge impact on academic or technological development.

Some highly difficult research may have no practical significance and may just be shelved.

The difficulty evaluation mechanism of system tasks is only related to the "research difficulty" and has nothing to do with the possible impact.

“So, the system is also very old-fashioned.”

"Like a cold machine, it just runs according to a fixed internal logic..."

Zhang Shuo was relieved.

At the same time, we are looking forward to research even more. Completing research tasks above level D will be rewarded with scientific research coins.

Scientific research coins are good things!
He calmed down, used the research coins obtained from the "minimum living allowance", quickly entered the research mode, and wrote the main algorithm framework according to the ideas in his mind.

The experimental data deviation analysis will be a repetitive calculation program supported by the main algorithm. Each repetitive calculation will be compared with the ideal simulation trajectory of the particle collision and evaluated using the "deviation evaluation system".

The simulated trajectory is the theoretically perfect state formed by particle collision.

That's the ideal situation.

Real particle collision experiments are affected by environmental factors, collision location, energy difference, etc., and the resulting particle escape trajectory images deviate from the simulated trajectory.

Normally, as long as a large number of experiments are conducted, the data is sufficient, and there are no interference from other factors, the resulting image will always be infinitely close to the simulated form.

That's the problem.

Analysis of particle collision experiments in the past has found that no matter how much data is input, the resulting image will not infinitely approach the simulated form, but will hover around a fixed deviation value.

This is the problem of trajectory deviation of massive particles.

The goal of Zhang Shuo's research and analysis algorithm is to analyze whether there is a problem of trajectory deviation of massive particles in the experiment.

Compared with super-large particle colliders, the performance of electron-positron colliders is not very high, the scale of experiments conducted is relatively small, and the analytical conclusions obtained are also very biased.

But even with less data, it is possible to find a signal.

His purpose was not to prove the existence of a trajectory deviation problem, he just wanted to conduct an analysis in the hope of finding a "possible signal".

This is very important.

The world we live in in our previous life and this life are very similar, but there are still differences in some research directions and contents, just like the parallel worlds in some physical theories.

Are the physical rules of parallel worlds consistent?
In order to continue to verify the "source point theory", we must first determine the consistency of physical laws.

This is also part of the research.

When Zhang Shuo was fully devoted to the algorithm research, Luo Yongjun had already completed the report. He read it carefully from beginning to end and couldn't help but smile with satisfaction.

After doing a simple layout and clicking the print button, he breathed a sigh of relief. Looking up, he saw Liu Chengjie standing behind Zhang Shuo, who was typing away at the computer.

He walked over with curiosity and saw Zhang Shuo writing code.

With the sound of keyboard clicking, lines of code quickly appeared on the screen.

That process and that speed seem to require no thinking at all, yet it is even faster than copying.

“Too professional, isn’t it?”

Luo Yongjun's expression was a little exaggerated. He also watched from behind for a long time and couldn't help asking, "What is this?"

Zhang Shuo's fingers stopped moving.

Maintaining the same posture for a long time made his whole body feel stiff. He did two chest expansion exercises and rubbed his hand joints with his left and right hands. Then he turned around and explained, "Design an algorithm to analyze the experimental data."

"What are you analyzing? Tell me in detail." Luo Yongjun immediately became interested.

"Is such that."

Zhang Shuo clicked the mouse and found the algorithm framework interface, then turned his chair and explained briefly, "This core algorithm will analyze and evaluate the experimental data."

"After the analysis and evaluation, each path will be compared with the simulated form of the particle collision experiment, and the deviation can be analyzed."

Luo Yongjun half opened his mouth and asked in confusion, "The deviation between the analytical experiment and the simulation? Why?"

"Perhaps there will be some discovery?"

Zhang Shuo asked back, and continued to explain, "Due to interference from environmental factors, collision location, and poor capabilities, the real image formed by the experiment must deviate from the simulated situation.

"But, as far as I know, no one has ever studied how big the deviation is from one experiment to another, and found an ideal situation where everything is simulated by computer."

Luo Yongjun frowned and thought for a long time before grasping a key question, "Will the amount of calculation be very large?"

"I've thought of a way."

Zhang Shuo pointed to the algorithm framework diagram on the screen and said, "Starting from the central data, we can connect the data of all locations one by one by making aiming points."

"The data analysis in the center is more complicated, so the data at the edge only needs to be substituted in, which can greatly reduce the amount of calculation." Luo Yongjun pursed his lips tightly, nodded thoughtfully, and suddenly he didn't know what to say.

He hopes to provide guidance to students in their research.

But I don’t understand it at all!

He thought it was impressive that he could understand what was said, while Liu Chengjie next to him simply acted as if to say, "I don't understand what you are talking about at all."

“This is a normal student.”

Luo Yongjun felt gratified, but still felt that he should say something in order to demonstrate the correct attitude of a doctoral supervisor.

He thought quickly and scratched his scalp with his hand, and ended up pulling out a few hairs.

His eyes suddenly lit up, and he said, "You want to compare it with the simulation, right? Don't worry about the simulation program part, I can help you apply for it."

"The experimental base must have such a program. Even if we can't apply for it, we can still make a connection." He added, "What you write yourself can only be an ideal simulation program. Every experiment is different, and the simulation program will also be different."

Zhang Shuo nodded and said, "It would be best if we had a simulation program for this experiment. This way, the comparison results would be more accurate."

Luo Yongjun was pleased that he could help. He smiled and continued, "Also, even if we try to reduce the amount of calculation, it's still huge, right?"

"Correct."

Zhang Shuo nodded vigorously.

Luo Yongjun continued, "It's unlikely to complete the programming in just a few days."

"First, you should complete the main framework algorithm part, which can be regarded as the research results of an experiment, and then write an introductory report."

"There will be a paper review at this experimental meeting. You can submit it for review first. If the Institute of High Energy Physics is interested, they will urge you to improve the algorithm program. By then, you may be able to get funding."

"If it doesn't work, it can be considered an experimental result. If it passes the review, it will be archived and counted as an experimental paper. It may also be published later, which will be beneficial to you personally."

Zhang Shuo thought for a moment and asked, "If the Institute of High Energy Physics is not interested, after I perfect the program, can I apply to use a large computer to verify the results?"

"Supercomputers are impossible..."

Luo Yongjun grinned vigorously. He was just an ordinary mathematics professor and had no ability to apply for a supercomputer.

The computing power of a supercomputer costs money. The startup and operation of a supercomputer are constantly burning money. Not counting the loss of hardware, just the normal operation state can burn tens or hundreds of thousands of dollars in a day.

He continued, "But I can help you apply to the school for the use of the computer lab's server."

"The server has less computing power, but it runs longer, so maybe that's OK?"

Zhang Shuo nodded and said sincerely, "Thank you, Mr. Luo."

"You're welcome."

Luo Yongjun exhaled lightly and smiled, "No matter what, I am your mentor, and helping students is my job."

……

Luo Yongjun picked up the printed report and left, leaving Zhang Shuo and Liu Chengjie alone in the office.

Zhang Shuo was about to continue his research when he saw Liu Chengjie pulling a chair and sitting next to him. He asked with a complicated expression, "Zhang Shuo, how come you are so amazing?"

"Uh~~~"

Zhang Shuo was silent for a moment, feeling that the question just now was strange.

Liu Chengjie continued, "I mean, look, you can work with Professor Luo, discuss problems, and do this kind of research..."

"I just watched you for a while and I feel like you are a professional programmer, and a very good one at that."

“This one~~”

Zhang Shuo stretched out in his chair and said hesitantly, "Maybe I'm working harder?"

"effort?"

Zhang Shuo turned his head and said, "Look, I've been working and doing research all the time."

"Right."

Liu Chengjie thought about it and realized that it was indeed the case.

In the office, Zhang Shuo has been working all the time, and when he is free, he either looks for a movie to watch or reads the news.

Even when working, it is common to be distracted.

"Then how can I do what you do? Is it enough to just work hard? I feel like no matter how hard I try, I can't do it in a short period of time?" Liu Chengjie continued to ask.

Zhang Shuo looked Liu Chengjie up and down, nodded affirmatively, "I think hard work will definitely be useful."

"Spend more time learning various knowledge and thinking more. When we learn mathematics, the most important thing is thinking."

"If you can't figure out a problem, just keep thinking about it..."

"Isn't that how most of the world's research is done? You're no worse than me, you can definitely do it."

He said this with a sincere look on his face.

"Really?"

Liu Chengjie smiled happily and waved his hand vigorously, "Okay! I'll listen to you and go read a book too!"

He walked back to his seat with full motivation.

Zhang Shuo pursed his lips tightly, feeling that he had done a good thing, and his mood became much better.

Lies can sometimes really help others!
