City: Signing in starts with getting mind reading skills

Chapter 14

After a long while, Professor Chang stopped asking, and sighed in admiration: "Although I didn't ask many questions, they were all the key points of knowledge in each chapter. Zhou Xiaoyu, you have indeed mastered all the knowledge of advanced mathematics through self-study, which is really great."

Professor Chang gave a thumbs up.

"You flatter me……"

Zhou Xiaoyu's rare old face flushed, after all his knowledge was copied.

Professor Chang said: "However, there is a flaw that I still want to point out. For example, the structure of the solution of the linear differential equation we discussed just now. You cited a latest research on the second-order linear equation in the supplementary chapter of the textbook. There are slight differences in the formal explanation. Errors, although they do not affect the final conclusion, mathematics is a very strict logical dialectics, and no errors can be tolerated, so pay attention!"

Zhou Xiaoyu listened humbly, and suddenly thought of something, his expression shook: "Teacher, I have a bit of a disagreement about this latest research proof of the second-order linear equation."

Although he copied the knowledge in Professor Chang's memory, he did not simply transfer it, but added his own thinking on the basis of his understanding, and went to a higher level. At this moment, combined with what Professor Chang said, he suddenly discovered an important problem.

Professor Chang snorted, "Say it."

Zhou Xiaoyu said: "If the functions y1(x) and y2(x) are both solutions to the quadratic power of the equation y + P(x)y+Q(x)y, then y=c1y1(x)+c2y2(x) is also the solution of the equation solution, which is called the superposition of the solution. But in this way, the solution obtained is not necessarily the latest general solution of the second-order linear equation, but in several cases. This shows that the latest research on the second-order linear equation proves that Uncertain, so..."

Speaking of this, Zhou Xiaoyu emphasized his tone: "It is very likely that what is written in the textbook is wrong!"

what?

Everyone was taken aback.

Although they heard the mist in front of them, they understood the last sentence.

Zhou Xiaoyu's research on questioning textbooks proved to be wrong!

Shocking!

Professor Chang was also shocked, but he didn't refute Zhou Xiaoyu. Instead, he picked up the textbook and looked at the relevant parts carefully.

While watching, he muttered in his mouth, as if he was calculating something.

After a while, Professor Chang raised his head suddenly, his face full of excitement: "Zhou Xiaoyu, you are right, this research should prove to be wrong."

I go……

Everyone gasped, full of shock.

You should know that although this advanced mathematics textbook is compiled internally by the school, the editors are all experts or doctoral supervisors like Professor Chang, and it has to go through several proofreadings, rigorous inspections, and confirm that it is correct before it can be published as a textbook.

Zhou Xiaoyu pointed out the mistakes. Could it be that his mathematics level has reached the height of an expert professor?

Professor Chang paced back and forth excitedly: "Zhou Xiaoyu, what a discovery you made! When we were compiling this textbook, there was controversy over this research proof, but in order to expand the content of the supplementary chapter, we still added it. One year Another year has passed, and no one has found the error until you point it out. This discovery is so important that it can help us overcome a series of mathematical problems related to the solution of linear differential equations, and even mathematics in general. It is a major breakthrough !"

Speaking of this, Professor Chang couldn't help being overjoyed, and suddenly bowed solemnly to Zhou Xiaoyu: "Student Zhou Xiaoyu, your contribution is very great. On behalf of our school and all colleagues who study mathematics, thank you. The mathematics community will remember you! "

Everyone opened their mouths wide open, dumbfounded.

Are they...witnessing history?

Zhou Xiaoyu hurriedly said: "Professor Chang, you're welcome. I actually discovered this problem by accident after being taught and inspired by you. It's just luck. It's nothing at all. Even without me, you would have discovered it sooner or later."

This is not modesty. The reason why he was able to discover this mistake was mainly because of the knowledge of Professor Chang. It has nothing to do with the level.

As long as Professor Chang jumps out of fixed thinking, he will soon find out.

Professor Chang said with emotion: "There is no need to be humble. Since ancient times, heroes have been born in youth, and the ancients have never deceived me. Come on! Zhou Xiaoyu, as long as you work hard, you will definitely be a mathematician in the future!"

clap clap clap...

After a moment of silence in the classroom, spontaneous applause from the students suddenly resounded.

At this moment, facing Zhou Xiaoyu, they no longer have any emotions, only admiration and respect.

Jingle Bell……

The school bell rang.

Professor Chang stepped down from the podium: "Xiaoyu, let's add WeChat and contact information. There are a lot of things involved in the research and proof, and it needs to be sorted out. You are the one who pointed out the mistakes. I must ask you for help. Of course, I also I won’t use you in vain, you will be subsidized. When you graduate, if you take the postgraduate entrance examination, you must give priority to me. As long as you pass the initial test, I will give you an exemption from the interview!”

"Okay, Professor Chang."

Zhou Xiaoyu quickly agreed, took out his mobile phone and added Professor Chang's WeChat and phone number, groaning inwardly.

In fact, he doesn't like mathematics at all, and he seems to be pretending a bit too much today...

Seeing this, the other students lamented that a top student is a top student. He was just a freshman, and some professors planned to accept him as a graduate student. Looking at themselves, they were still worrying about how to pass the exam.

Students under the same roof, why is there such a big gap.

"goodbye students."

Professor Chang left happily.

"goodbye teacher."

The students are also very happy, because after class is the weekend, they can have fun.

"Zhou Xueba, please accept my worship!"

"Xiaoyu, how did you learn by yourself, can you impart some experience?"

"Zhou Xiaoyu, I want to ask you about advanced mathematics alone, what time is convenient for you?"

Many students surrounded Zhou Xiaoyu enthusiastically, as if fans saw their idols, and some bold female students even proposed dates in the name of studying.

No matter where, Xueba is welcome.

The girls also found that Zhou Xiaoyu was much more handsome than usual, especially his figure, tall and strong, full of masculinity, very attractive.

Why didn't I find this treasure before?

Li Xinran cast a gloomy glance at Zhou Xiaoyu, who was overwhelmed by the stars, and left the classroom silently.

In the past, because of his good studies, he always had a sense of superiority, and felt that Zhou Xiaoyu and others were inferior to him, even if he was cleaned up by Zhou Xiaoyu last night.

But today, his sense of superiority was completely shattered.

"I'm sorry, students, I still have something to do, so I'm leaving first."

Zhou Xiaoyu was in a hurry to go home, and with a few casual words, he woke up Zhao Mingqiang and Wang Jintao, who were sleeping like dead pigs, and left.

Back in the dormitory, Zhao Mingqiang and Wang Jintao fell on the bed and continued to sleep soundly.

Zhou Xiaoyu simply packed up his things and left the school.
