Xueba: The knowledge I teach, critical hits are returned

"I wrote these papers"......

All of a sudden, everyone in the 201 lecture hall looked at the door.

A young man stood at the door of the classroom. He was dressed in ordinary clothes, tall, a little thin, but with three-dimensional features. He was holding the door frame with one hand and breathing heavily.

Seeing Gu Bai at the door, all the senior students in the classroom were stunned for a moment.

But immediately, all the senior students had a thought in their minds: This kid......Was it Wu Hai who invited him to take the blame?

Because from the outside, Gu Bai looked less than 20 years old. Although he looked like a good student,...Too young, at most a sophomore, maybe even a freshman.

Professor Luo Shifei on the stage just now also said that these 11 papers were written by one person in less than a month.

They would not believe that a freshman has such strength.

When Wu Hai saw that Gu Bai really came, a hint of hope appeared on his face, but he did feel a little guilty.

Professor Luo Shifei standing on the stage was also slightly stunned.

Of course...He thinks differently from everyone else.

""Why is it this guy?"

Luo Shifei frowned, and he obviously recognized Gu Bai.

Some time ago, Luo Shifei was the invigilator for the Advanced Mathematics 2 exam of the Department of Nonwoven Materials and Engineering. Because Gu Bai handed in his paper early and got full marks, he was impressed. After the exam, he asked Professor Yao Qizhi to transfer Gu Bai to their Department of Mathematics.

But he didn't expect that this guy would come to help Wu Hai?

Luo Shifei had the same idea as other mathematics students. He didn't think that these 11 papers were written by Gu Bai.

Although Luo Shifei thought that Gu Bai had a good talent for mathematics, Gu Bai was only a freshman after all.

Besides, these 11 papers were graduation theses for seniors in mathematics. Gu Bai had never learned many mathematical formulas, and...Just relying on a full-mark test paper in advanced mathematics doesn't mean much.

Luo Shifei smiled and said,"You said you wrote the 11 papers of Wu Hai and others?"

"That's right." Gu Bai nodded in acknowledgement.

He had already been discovered, so Gu Bai didn't intend to hide it. At worst, he would give up the money and let senior Wu Hai and the others rewrite it. Anyway, it wasn't time for the final graduation defense.

"Ah~~"Luo Shifei shook his head, a little disappointed, but didn't say anything.

Someone in the audience couldn't help but shout,"Brother, take it wherever it's cool. This is our senior year mathematics department graduation thesis, not your simple advanced math problem."

Hahaha, everyone laughed immediately

"Wu Hai, where did you find this actor? You didn't even bother to find an older one?" The mathematics department monitor glared at Wu Hai and said with some dissatisfaction.

As the monitor, he certainly didn't want his classmates to be unable to graduate because of the graduation thesis issue.

But now things are obviously heading in a worse direction. Professor Luo Shifei hates lying the most.

Wu Hai was a little helpless. What he said was the truth, but no one believed him.

Hearing the laughter of the students below the stage, Gu Bai was not angry, but Luo Shifei's expression became serious. He looked at Gu Bai and asked calmly:"In the first year of your major, you should have only studied two books, Advanced Mathematics 1 and 2, right?"

"That's right."Gu Bai said

"Come and have a look at these papers: Research on two problems in probability theory and random processes, Analysis of the problem of finding the maximum value of a function using geometric knowledge, Convergence of random variable series and their mutual relationship...."

"....Which of these papers can be solved using the textbook knowledge of Advanced Mathematics 1 and 2?"

"Especially this one." Luo Shifei pointed to one of the papers, titled"Laplace Transform and Its Properties in Random Processes", and looked at Gu Bai with a hint of anger in his eyes:"Laplace transform, this is something we don't even learn as undergraduates? You told me that you wrote this, how did you write it, what did you use as a freshman to write it?"

"Nonsense, really nonsense!!!"

Professor Luo Shifei was a little angry.

Originally, he had a good impression of Gu Bai. He admired some talented mathematicians, but...At this time, Gu Bai still insisted that he wrote it, and he was not going to show any mercy.

Seeing Professor Luo Shifei about to go berserk on the stage, all the students in the audience looked at Gu Bai with pity.

Wu Hai felt even more guilty. He regretted that he should not have sent a message to Gu Bai, and he should have insisted on it.

But it was too late to say anything now.

"Go, go directly, Gu Bai." Wu Hai prayed in his heart.

However...

Gu Bai did not leave.

As soon as he saw Luo Shifei's expression, Gu Bai knew that Professor Luo Shifei did not believe him.

But... this is what he wrote, and he typed it out word by word.

After a pause, Gu Bai recalled the content of the paper and said lightly:"'Laplace transform' is the same as 'Fourier analysis'. It is a kind of integral transform commonly used in engineering mathematics, but compared with the reductionism and analytical specialism of 'Fourier analysis', Laplace transform is a linear transformation that can convert a function with a parameter real number t (t≥0) into a function with a parameter complex number s, so it is more widely used....."

"...The paper I wrote used the initial value solution of the backward stochastic differential equation, that is, using the equation F(s)=∫∞0_f(t)??-The convergence factor of a complex function that transforms a time domain function into a complex frequency domain in tdt...."

Gu Bai described the entire process of the paper and its logical thinking.

His voice was not loud, but...But it reached everyone's ears.

At this moment.

The entire...Professor Jieti 201's senior mathematics students all looked at Gu Bai on the stage with a blank face.

What the hell is he talking about, is it Chinese?

Yes.

But why can't I understand?

Only Professor Luo Shifei standing on the stage calmly supported his eyes, thinking that this paper that is fully qualified to be submitted to SCI Weekly couldn't really be written by this kid.

However, how is this possible?

Freshman, he is only a freshman! What was he doing when he was a freshman?

Digging mud? That's not the case, but...when he was a freshman, he, Luo Shifei, was definitely not as good as the young man in front of him, even those professors from Tsinghua and Peking University were definitely not as good as the young man in front of him. Of course, Luo Shifei had read this paper that was qualified to be submitted to SCI, and he was very careful.

Putting aside some minor flaws, this paper, whether it is the calculation process, proof logic, or mathematical application, can't find any problems at all, and even some mathematics weekly editors will directly pass the review. Are freshmen so competitive now?

Is this what freshmen should do?.........................................
