I Exchange For Black Technology By Blowing Up The Bully

Gong Shasha was stunned, "Really, do you still read mistakes in college papers?"

Nie Jun couldn't believe it, "Can't it? This is a public paper. If there is a mistake, how can the review teacher not see it?"

Wu Xiaole laughed, he just took it as a joke, "When it comes to bragging, we have to watch Song He! I almost pretended it for you!"

Several other people present didn't believe it at all, only Xu Tingfeng was dubious, frowning and examining Song He.

"Undergraduate thesis review is very loose, because undergraduates have not yet entered the scientific research stage, and the teacher knows that a rooster cannot lay golden eggs, so when reviewing, he only looks at the format and the source of the data." It's normal."

Song He praised, "Yes, Xu Tingfeng, you know how to do it."

"So you found the right and wrong data, right? Some text descriptions are wrong?" Xu Tingfeng asked.

"No, it's just the wrong data!" Song He denied

As soon as these words came out, the scene became silent again.

The eyes of the others became even more suspicious, this time even Xu Tingfeng was seriously suspicious.

Although the undergraduate thesis is poor, it has also been reviewed by the university, and the key scope of the review is the data!

Serious data error or data falsification, once found out, is academic misconduct, and the degree certificate will be revoked!

After the degree certificate is revoked, not only the unlucky students will lose their university studies, but even the related majors of the university will be implicated!

If academic misconduct is detected in the first year, the scope of spot checks will be expanded in the second year. If there are any more problems, the entire major will even be disqualified from running the school, and teachers and school leaders will be suspended. The consequences are extremely serious!

Therefore, under normal circumstances, all public undergraduate papers, although they are flooded and non-nutritious academic garbage, are at least correct garbage without obvious mistakes.

Song He said that the data was wrong, which caused other people present to be suspicious.

What obvious mistakes can a high school student spot at a glance?

What mistakes can be seen by high school students, can't the professors reviewing papers in universities see?

"Tell me what's wrong." Xu Tingfeng was full of curiosity, "Let me judge."

"I'm afraid you don't understand." Song He chuckled.

The few people present were speechless and rolled their eyes at him, feeling like they were being played. Isn’t it a lie to keep saying that the thesis has errors, but you find an excuse not to mention the specific errors?

"I am the champion of the biology competition team!" Xu Tingfeng reminded.

"That's right, I'll explain it to you, maybe you can understand." Song He spread Yi Chunxiao's papers on the table.

Everyone present immediately turned their heads over.

"I'll tell Xu Tingfeng, why are you joining in the fun? Do you understand?" Song He was surprised.

"My biological score is higher than yours!" Wu Xiao bared his teeth angrily, "Song He, don't pretend to be a wolf with a big tail. What mistakes can you find in this undergraduate paper? I will expose your tricks on the spot!"

[Wu Xiao is despised by you, and feels resentful, resentment value +200! 】

[Gong Shasha feels underestimated, and feels unhappy, resentment value +100! 】

[Nie Junren feels a little embarrassed, resentment value +100! 】

After successfully reaping a wave of resentment, Song He no longer kept a secret, and turned to the paper data page.

"Look at this set of data, the random number of bacteria in hundreds of petri dishes, look at the first number, did you find anything?"

Several people frowned and looked at it for a long time, all with blank faces.

"Among the first digits, 1 accounts for only 5%, while 8 accounts for as much as 20%. The distribution of other numbers is as weird as an electrocardiogram. Have you heard of Benford's Law?"

Seeing that everyone showed a dumbfounded expression, Song He sighed helplessly, with a look of resentment.

"A lot of real data in real life, the number with 1 as the first digit accounts for about 30.1%, 2 is 17.6%, and then it gets lower and lower, until 9 is only 4.6%."

"For a set of average growth data, the time it takes for the initial number a to grow to another number starting with a+1 must take more time than the number starting with a+1 to grow to a+2, and the occurrence rate will increase become higher. Is this easy to understand?" Song He explained.

Wu Xiao was dumbfounded, she has always been bad at math, and now she is listening to heaven.

Nie Junren and Gong Shasha were thoughtful, and they still had a little understanding of pure mathematics.

"I've heard of Benford's Law, which is used to simply judge data falsification." Xu Tingfeng nodded, "But the data sample in this paper is not large enough, what if it happens by chance? After all, Benford's Law is not 100% applicable , there are always some special circumstances.”

"Yes, yes, you can't just take a mathematical law and slander this paper as a falsification, right?" Wu Xiao's eyes lit up, and he quickly agreed.

Nie Junren and Gong Shasha exchanged glances, and both felt that Song He was being unreasonable.

"Don't worry, Benford's law is only a rough test, which makes you vigilant, and then you have to use the knowledge in the biological field to judge." Song He said calmly.

The four present stared at him suspiciously.

"The experiment in this paper can be applied to the classic Luria–Delbrück experiment. Old Xu, you should know, right?"

When Xu Tingfeng heard it, his face suddenly changed. He grabbed the paper and stared at it carefully, and suddenly realized.

"So it is!" Xu Tingfeng exclaimed.

The other three were still confused and looked at Song He in surprise.

Song He had no choice but to communicate with a master like Xu Tingfeng, but it was troublesome to communicate with other idiots, and it took a lot of talking.

"The Luria–Delbrück experiment is one of the most important experiments in modern molecular biology."

"The problem to be solved in the experiment is how to judge whether the mutation of the bacteria in the petri dish is due to the influence of the environment, or whether the bacteria themselves are bored and have nothing to do with the mutation."

"If the number of colonies conforms to the binomial distribution, the mean and variance are almost the same value, indicating that the bacteria are mutated by environmental influences."

"If the colony has a typical long-tailed distribution, it is very likely that the bacteria are bored and mutating themselves."

Song He flipped through the paper, poked at the previous text description, and spoke firmly.

"Yi Chunxiao's paper is also in a similar situation. There will be errors in the data, but the overall trend will not change. That's why I judge the paper to be wrong!"

"Either she falsified the data, compiled the data or compiled it unprofessionally. Or there was a problem with the experimental environment, the petri dish was contaminated, the bacterial sample failed to be preserved, and the bacteria interfered."

"Anyway, Yi Chunxiao's thesis is correct, I'll just eat it!"

Wu Xiao, Nie Junren and Gong Shasha couldn't hear it, so they had to turn their heads to look at Xu Tingfeng.

Xu Tingfeng didn't directly make a judgment, but dragged the draft paper from the side, picked up a pen and calculated for a long time.

The data that Song He can calculate mentally at a glance, but for her, she has to go through tedious calculations. It's not that she is poor in math, it's mainly because Song He's math level is too bad.

After a long wait, Xu Tingfeng finally put down his pen with a "snap".

"Song He is right! There is indeed a problem with the data!" Xu Tingfeng raised his head and looked at Song He with admiration, "Amazing! His eyes are sharp!"

Wu Xiao was dumbfounded, his cheeks were flushed, and he felt like he was being slapped in the face.

Song He is already this strong? Even Fengfeng turned against him and praised him for his strength?

Could it be that this stinky brother can really surpass me in the next big exam? Wu Xiao felt apprehensive, with a worried look on his face.

Nie Junren and Gong Shasha were shocked.

Both of them thought that Song He couldn't understand college papers, and this errand was purely for nothing. Never expected that Song He could understand it, and even find out the mistakes?

Everyone present suddenly remembered that Song He corrected the biology test book earlier, which caused an uproar in the whole school.

Everyone stared at Song He with strange eyes, Ning is the master of error correction?

Song He finished reading Yi Chunxiao's thesis, quickly wrote down the judgment basis of the data error from the blank space, and handed it to Nie Junren.

Nie Junren took it with his hand, puzzled, "I'm a math competition student, why do you give me a biology paper?"

"Tomorrow you two are going to print your thesis, and give her Yi Chunxiao's thesis by the way, tell her there is an error, and save her life!" Song He ordered, "There will be random checks on the papers within a few years after graduation. Rectification in advance can avoid a catastrophe!"

"Do you want to print papers tomorrow?" Nie Junren's expression turned bitter.

"More than that, the box printed today is just an appetizer, and I'm afraid we'll have to print seven or eight boxes tomorrow." Song He smiled, "Coolery isn't hard work, so it can still be called coolie?"

[Nie Jun was arranged to work hard by you, his mentality collapsed, and his resentment value +500! 】

[Gong Shasha was so tired that she almost fainted, she was terrified, her resentment value +700! 】

[Biological progress detected, upgraded from silver level 32 to silver level 33! 】

...

Evening, dormitory.

There was a clatter of keys outside the door, and then the dormitory door opened.

Song He entered the room, quickly closed the door and locked it, with a sneaky look on his face.

"Bang!" A box of papers in his arms was thrown on the ground, he raised his leg and kicked, and the box slid to the corner.

The dormitory area is large enough, and the corners are very wide. It is estimated that many boxes of papers can be placed.

Song He sat down panting. Usually, he would return to the dormitory after the evening self-study, but today he slipped back before the evening self-study.

He wanted to do something private, and it was not good for Yuan Guang to see him.

This matter has to be done as soon as possible, and I rushed back to the classroom for evening self-study. It is the habit of the class teacher to go to the classroom on Sunday night for self-study and count the number of people.
