Rebirth of the God-level Xueba

"Hey? What does this guy do? It'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, "I am a graduate student from another school. I want to take the Ph.D. of our school, thinking I'm going to spoil him?"

"This person, I think he is a person." Mao Qiming muttered, "I wasn't here just now, or else, listening to him talking to you like this, I have to slap him so that he knows the rules and misses us." At the time of high school, students from other schools had to bow their heads when they came to this school, otherwise, be careful not to be beaten... ah, the rest of the meal ticket."

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

"Just keep it. There will be a party next time. If I'm not here, you will pay the money." It's almost a week since school starts. Yang Rui usually eats out. On Friday, he invites his classmates in the school cafeteria, whoever wants to come. Come, he just pays the bill, no matter what the person is doing.

　　Using this method, Yang Rui's reputation quickly improved. Although the evaluation of big money is inevitable, it is actually more of a positive evaluation.

On the surface, his manuscript fee is as much as several thousand yuan, and in the canteen of Peking University, it is rare to spend 20 yuan for a meal. Most of the time it is about ten yuan. Please everyone once a week. Not prominent.

　　Wang Yaping or a researcher in the laboratory, if they consciously helped, they would come and have a meal at ease. Those students who were nervous on the weekend, and some who were not so comfortable would come and have a meal, Yang Rui didn't care about it.

　　 Mao Qiming is the only student who often comes to the dormitory. He has a very active temperament and joined the student union with Yang Rui's help, so he deliberately walked very close to Yang Rui, and was willing to help Yang Rui deal with some trivial things in the dormitory from time to time.

Hearing Yang Rui said that he was receiving the money, Mao Qiming happily picked up the money, consciously being trusted, and said: "I will go back to make a small book and keep the accounts. By the way, are the students from outside school still here? Looks pretty good. Obviously old, let's work."

　　 "It should be a job, an educated youth, after going to university and then going to graduate school." Yang Rui said casually.

"When you come back, you must call me, you have to teach him some rules." Mao Qiming raised a little thin arm, made two gestures in the air, and said: "Being honest is important, right? You can't just come here and just talk nonsense, why are you? It might be bad for him."

　　Yang Rui smiled and said, "There is indeed a misunderstanding."

　　 "So, hey, how do you misunderstand, do you know a professor who can accept a Ph.D.?"

　　 "I don't know, so it was a misunderstanding. He thought I told the professor something, but I didn't actually say it." Yang Rui said halfway, and he quietly hid what he said to the outside world.

　　 "You have a very good temper, so you don't let people 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.

　　 Li Xin, who left the canteen, walked around the campus of Peking University before returning home.

　　He deliberately stimulated Yang Rui.

Li Xin is not afraid that Yang Rui will seek help from the "relatives of the Department of Higher Education". In the end, he will be replaced by another professor to test his doctoral students. There are no doctoral students who are optimistic about Professor Li in advance. The other doctoral supervisors are all academic, yes. For Li Xin, there is no difference.

　　 Li Xin changed a professor's doctoral student to take the exam, basically there is no cost, and Yang Rui wants to prevent him from taking the doctoral student of a certain tutor. As Li Xin wanted to come, it was costly.

　　 So, Li Xin was a little bit expecting Yang Rui to stop him. He provoked and went to see Professor Tao again. He didn't notice that Professor Tao's attitude had changed, so he felt relieved and thought: If Yang Rui just gave up.

　　 Yang Rui naturally did not give up.

　　 He just used a method, completely different from Li Xin's imagination.

　　 He didn't even spend much time on himself, he just borrowed the resources of 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 redoed the experiment, saw Yang Rui again and disdainfully commented on Li Xin's experiment, saying: "It was originally a very simple experiment. He didn't do it well, so he had to guess..."

　　 "Did you guess right?" This is the main point that Yang Rui pays attention to.

　　Academic fraudsters are not fools. Simple academic frauds are usually caused by the researchers failing to make the desired experimental results to match the themes or conclusions of their thesis, so they create false figures and even false charts.

　　 Sometimes, they are right, sometimes they are wrong, and the purpose of the experiment is the same to test whether the theory is correct.

Therefore, whether academic fraud can be discovered often becomes a probability question. Sometimes, some people can guess the experimental results even if the experimental steps are omitted. In the face of such academic fraud, it will be difficult to expose. too much.

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

　　 "Why?"

"There is a problem with his experimental foundation, and there should be a collective deviation. 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 deviation. Then, the data can be used. As a result, there is no offset in his data, so it is determined that it is a fraud." Wei Zhen said a little proudly.

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

Especially the less rigorous collectives are cheap, and some data will be quite confusing. Saying that 2468 becomes 3579 means that the collective has shifted 1 position to the right. The judgment of 2378 is not easy to say, when the data changes very much. When it's complicated-think about the nauseous Mathematical Olympiad, and you can see the difficulty of some parts.

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

　　 Find someone else to falsify. If you find that your data is wrong, it will be embarrassing.

　　 At the request of Yang Rui, Wei Zhenxue’s experimental records were very complete.

　　 This is a good habit. When the experiment record can fully reflect the experiment, the wrong experiment becomes as valuable as the correct experiment. If something goes wrong, you can find the reason through the experiment log.

　　 When Yang Rui was a scientific research dog, he seldom paid attention to this point—the scientific research dog didn’t need much brains, and he didn’t need to use experimental records to judge conclusions. It just had to work.

　　 But when Yang Rui progressed to scientific research 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 are from different manufacturers, and there is no complete experimental record. The two experiments could not be done completely.

　　 It can be seen from Wei Zhenxue’s experimental records that the deviations in his first few experiments were very large, but the deviations were concentrated in a certain area.

　　 Next, Wei Zhenxue did several more experiments based on this, determined the deviation value, and thus determined the final curve.

　　 Compared with Li Xin’s paper, Wei Zhenxue’s experiments have increased the difficulty, and the difficulty of data processing has also increased several times, and before the calculation, the probability of obtaining the desired conclusion is also reduced.

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

"To be fair, it is estimated that it took a lot of time to set up his thesis, and then to wait for funding, and then determine the target. Time is tight, money is tight, and it is possible that I can't achieve the result like mine." Wei Zhenxue suddenly went into boasting again. Mode, said: "Of course, to achieve results like mine, the level is not enough..."

“It’s true that graduate students are under great pressure. He spent more than a year writing three papers, and an average of one is half a year. If the work is not smooth or the funding is not in place, he may not be able to finish the experiment. .Uukanshu.com However, this is not the reason for falsification. He has one thesis that is enough to graduate, and he pursues three papers and then completes it by falsification?" Yang Rui shook his head and said, "He is just staring at the doctor's goal. of."

"Perhaps."

"Okay, publish the paper, and then send a letter to his thesis editor, let them deal with it." This is not an academic dispute, there is no need to write fraud in the paper, Wei Zhenxue published his thesis as usual, but published the Li Xin paper For journals, they will naturally find a way to solve the problem, usually withdrawing the paper and notifying the unit.

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

　　 "There are others." Before Wei Zhenxue's pride was gone, he said, "I found something else by the way."

"other things?"

　　 "Metal glass, I reworked iron-based glass, and the final product I got, I feel that the soft magnetic properties seem to have improved."

　　 "Feeling?"

　　 "I didn't find similar documents, but compared the performance of the finished products on the market, it should be improved." Wei Zhenxue was a little excited in his words, and it was not the same to do physical 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 is fine, not bad. This is the first result in our laboratory. If we can earn back the experiment cost, I will give you a bonus!"

　　 It is a rare joy in the laboratory to produce extra surprises by doing research, and there are many laboratory legends born from this.
