Rebirth of the God-level Xueba

"Huh? What does this guy do? He's very arrogant." Mao Qiming brought the braised pork to the table, looked at Li Xin's swaying back, and curled his lips in disdain.

Yang Rui smiled and said, "He's a graduate student from another school. He wants to get a doctorate from our school. Do you think I'm going to spoil his good deeds?"

"This man, he already considers himself a character." Mao Qiming said in a broken voice, "I wasn't here just now, otherwise, listening to him talking to you like this, I would have to give him a few slaps to let him know the rules and miss us. When I was in high school, students from other schools had to keep their heads down when they came to our school, otherwise they had to be careful not to be beaten... Well, the leftover meal tickets."

Mao Qiming put the braised pork on the table, and returned the extra meal ticket to Yang Rui.

"You keep it. There will be a party next time. If I'm not here, you can pay the money." It's almost a week since the start of school, and Yang Rui usually eats out. On Fridays, he invites classmates in the school cafeteria. Come, he just pays the bill, no matter what the visitor does.

Using this method, Yang Rui's reputation quickly improved. Although it was unavoidable to have comments from the big money, in fact, most of them were positive comments.

On the surface, his manuscript fee is as much as several thousand yuan, but in the cafeteria of Peking University, it is rare to spend 20 yuan for a meal, and most of the time it is around ten yuan. does not stand out.

Wang Yaping or the researcher in the laboratory, if they consciously help, they will come to have a meal at ease, and some students who are nervous on weekends will also come to have a meal not so comfortable, Yang Rui doesn't care.

Mao Qiming is the only student who often comes to the dormitory. He has a lively personality, and with Yang Rui's help, he joined the student union, so he deliberately got close to Yang Rui, and was willing to help Yang Rui with some trivial matters in the dormitory from time to time.

Hearing that Yang Rui said he was taking the money, Mao Qiming happily put the money away, feeling trusted, and said: "I'll go back and make a small book to keep accounts. By the way, are the students from other schools still coming? It looks pretty good." Look old, let's go to work."

"It's time to work, educated youth, after college and graduate school." Yang Rui said casually.

"Call me again, and you have to teach him some rules." Mao Qiming raised his thin arm, gestured twice in the air, and said, "The most important thing to be a human being is honesty, right? You can't just come here and talk nonsense, why don't you It might be good for him.”

Yang Rui chuckled and said, "There is indeed some misunderstanding."

"So, hey, why did you misunderstand, you know a professor who can accept a doctorate?"

"I don't know him, so it's a bit of a misunderstanding. He thought I told the professor something, but I didn't say anything." Yang Rui said halfway through his speech, and he quietly hid his words for the outside world.

"You have such a good temper. If you do this, don't let others ride on your face. Next time this graduate student comes again, you must call us." Mao Qiming said, stretched out his chopsticks, and rushed towards the braised pork.

After leaving the cafeteria, Li Xin walked around the Peking University campus before returning home.

He deliberately went to stimulate Yang Rui.

Li Xin is not afraid that Yang Rui will ask "relatives of the Department of Higher Education" for help. At worst, another professor will take the exam for his doctoral students. Without Professor Li's doctoral students whom he is optimistic about in advance, the other doctoral supervisors are all academic. For Li Xin, there is no difference.

For Li Xin to change another professor's doctoral student to take the exam, it basically cost nothing, but if Yang Rui wanted to prevent him from taking the exam for a certain supervisor's doctoral student, according to Li Xin's thinking, it would cost a lot of money.

Therefore, Li Xin expected Yang Rui to stop him. He provoked him and went to see Professor Tao again, but he didn't find any change in Professor Tao's attitude.

Yang Rui naturally did not give up.

The method he just used was completely different from what Li Xin had imagined.

He didn't even spend much time on himself, he just borrowed resources from Wei Zhenxue and the laboratory.

The time spent by Wei Zhenxue and the resource consumption of the laboratory were far less than the two expected.

"This person is too lazy." Wei Zhenxue, who had redone the experiment, saw Yang Rui again, and commented on Li Xin's experiment with disdain, saying: "It was a very simple experiment, but he didn't do it well, so he had to guess..."

"Guess right?" This is the main point of Yang Rui's attention.

People who commit academic fraud are not fools. Simple academic fraud usually starts with the researcher failing to produce the desired experimental results to meet the theme or conclusion of his thesis, so he creates false numbers or even false charts.

Sometimes they're right, and sometimes they're wrong, and that's what experiments do, to test whether a theory is right.

Therefore, whether academic fraud can be discovered often becomes a question of probability. Sometimes, some people can guess the experimental results even if the experimental steps are omitted. Faced with this kind of academic fraud, it is difficult to expose it. too much.

Wei Zhenxue smiled and said, "If you guessed right, you guessed right, but his data is impossible to appear."

"why?"

"There is a problem with his experimental basis. There should be a collective offset. Therefore, if he really does the experiment and completes it, he will find that there is a problem with the data. After careful processing, he should be able to find the collective offset. Then, the data can be used. As a result, there is no offset in his data, so it must be fake." Wei Zhenxue said a little proudly.

He said it was easy, but it is not easy to find such data problems. It takes a lot of calculations and a little bit of luck to find them.

Especially if the collective is not rigorous, some data will be quite confusing. Saying that 2468 becomes 3579 means that the collective has shifted to the right by 1 position. The judgment of 2378 is not good. When the data changes a lot When it's complicated - think about the disgusting Mathematical Olympiad, and you can get a glimpse of some of the difficulty.

"Let me take a look." Yang Rui took Wei Zhenxue's experiment records and checked them line by line.

It will be embarrassing if you find out that your data is wrong if you find someone else to make a fake.

At Yang Rui's request, Wei Zhenxue's experimental records were very complete.

This is a good habit. When the experimental record can fully reflect the experiment, the wrong experiment becomes as valuable as the correct experiment. If something goes wrong, the cause can be found through the experimental records.

When Yang Rui first worked as a scientific research dog, he paid little attention to this point—a scientific research dog doesn’t need much brains, and it doesn’t need to judge conclusions through experimental records, it just needs to work.

But when Yang Rui progressed to scientific research on migrant workers, he gradually discovered the benefits of experimental records.

In many cases, the similarities and differences between the two experiments may be due to the fact that the two bottles of reagents come from different manufacturers and there is no complete experimental record. The two experiments may not be done for nothing.

From Wei Zhenxue's experimental records, it can be seen that his first few experiments had large deviations, but the deviations were concentrated in a certain area.

Next, Wei Zhenxue conducted several more experiments based on this, and determined the deviation value, thereby determining the final curve.

Compared with Li Xin's paper, the difficulty of Wei Zhenxue's experiment has increased, and the difficulty of data processing has also increased several times. Before calculation, the probability of getting the desired conclusion is also reduced.

"It's really a lazy guy." Yang Rui gave a similar evaluation.

"To be fair, it probably took a lot of time for his dissertation project to be established, and then to run funds and other funds, and then determine the goal. Time is tight, money is tight, and it is possible that I can't achieve the results like me." Wei Zhenxue went into boasting in a flash Mode, said: "Of course, if you want to make a result like mine, you don't have enough skill..."

"It's true that graduate students are under a lot of pressure. He spent more than a year writing three papers, and an average of one paper is half a year. It’s not a reason for falsification, he has one thesis enough to graduate, pursue three thesis, and then use falsification to complete it?” Yang Rui shook his head and said, “He’s just aiming at the goal of a doctorate.”

"Maybe."

"Okay, let's publish the paper, and then send a letter to the editor-in-chief of his paper to let them deal with it." This is not an academic dispute, there is no need to write fakes on the paper, Wei Zhenxue published his paper as usual, and published Li Xin's paper The journals will naturally find a way to solve the problem, usually by withdrawing the paper and notifying the unit.

Li Xin's master's degree will also be in jeopardy.

"There are other things." Wei Zhenxue's complacent look did not go away, and he said: "I found something else by the way."

"Something else?"

"Metallic glass, I reworked the iron-based glass, and the final product I got seems to have improved soft magnetic properties."

"Feel?"

"I didn't find any similar documents, but after comparing the performance of the finished products on the market, it should be improved." Wei Zhenxue was a little excited in his words, and it is still different to make real objects and pure laboratory research.

Yang Rui was also pleasantly surprised, and said: "As long as the performance is better than the finished product on the market, it's fine. This is the first result produced in our laboratory. If you can earn back the experiment fee, I will give you a bonus!"

It is a rare joy in the laboratory to make extra surprises for researchers, and there are many laboratory legends born from this.
