Xueba: The knowledge I taught will be returned by crit

“I wrote these papers.”

……

Suddenly, the eyes of everyone in the 201 lecture hall looked at the door in unison.

At the door of the classroom stood a young man, dressed in ordinary clothes, tall, a little thin, but his facial features were very three-dimensional, and he was panting with one hand on the door frame.

Seeing Gu Bai at the door, the seniors in all classrooms were stunned for a moment.

But immediately, all the seniors had a smear of thought in their heads: This kid… Did Wu Hai invite him to apologize?

Because from the outside, Gu Bai’s age is less than 20, although he looks like the kind of good study, but… Too young, sophomores at most, maybe even freshmen.

And 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 wouldn’t believe that a freshman had such strength.

Wu Hai saw that Gu Bai really came, and his face also showed a hint of hope at this time, but he did feel a little guilty in his heart.

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

Of course… He thinks differently from everyone else.

“How is this kid?”

Luo Shifei’s brows frowned, obviously he recognized Gu Bai.

Some time ago, the exam of Advanced Mathematics 2 in the ‘Nonwoven Materials and Engineering’ Department was proctored by Luo Shifei, because Gu Bai handed in the papers in advance and also scored a full score, so he was impressed, and after the exam, he also asked Professor Yao Zhizhi to let Gu Bai transfer to their mathematics department.

But I didn’t expect that this kid actually came to help Wu Hai?

Like other math students, Luo Shifei did not think that these 11 papers were written by Gu Bai.

Although Luo Shifei felt that Gu Bai’s mathematical talent was good, Gu Bai was only a freshman after all.

Besides, these 11 papers are all graduation theses of the fourth year of mathematics, and many mathematical formulas Gu Bai has not learned, and… A perfect score paper in advanced mathematics alone doesn’t say much.

With a smile, Luo Shifei said: “You said that Wu Hai wrote their 11 papers? ”

“That’s right.” Gu Bai nodded and acknowledged.

It has already been discovered, Gu Bai does not plan to hide it, it’s a big deal that the money is not needed, let the seniors Wu Hai write it again, anyway, there is no final graduation defense.

“Huh~~” Luo Shifei shook his head, a little disappointed, but did not speak.

Some of the students in the audience couldn’t help but shout: “Junior, go there and take it with you wherever it is cool.” This is our senior math thesis, not your simple high-math topic. ”

Hahaha, everyone laughed all of a sudden.

“Wu Hai, where did you get the actor? Don’t know if you’re looking for an older one? The head of the mathematics department glared at Wu Hai and said with some dissatisfaction.

As a class leader, he definitely does not want his classmates to fail because of their graduation thesis.

But now things are clearly going in a worse direction, and Professor Luo Shifei hates lying the most.

Wu Hai was a little helpless, he was telling the truth, but no one believed it.

Hearing the laughter of the students in the audience, Gu Bai was not angry, and Luo Shifei’s expression became serious, he looked at Gu Bai and asked lightly: “You should only learn two books of advanced mathematics 1 and 2 in the first year of your major, right?” ”

“That’s right.” Gu Bai said.

“Come, you take a look at these papers: the study of two problems in probability theory and stochastic processes, the analysis of the maximal value problem of finding functions using geometric knowledge, the convergence level of random variable columns and their interrelationships…”

“…. Which of these papers can be solved with book knowledge of Advanced Mathematics 1 and 2? ”

“Especially this one.” Luo Shifei put one of the papers called “Laplace Transform and Its Properties in Stochastic Processes”, and looked at Gu Bai with a hint of anger in his eyes: “Laplace transform, this is something we don’t learn in college?” You told me that you wrote it, how did you write it, what do you write as a freshman? ”

“, really!!!”

Professor Luo Shifei was a little angry.

Originally, his impression of Gu Bai was still good, he appreciated some talented mathematics, but… At this time, Gu Bai was still biting that he wrote it, and he was not ready to show mercy.

Seeing Professor Luo Shifei on the stage who was about to run away, all the students in the audience looked at Gu Bai with pity at this moment.

Wu Hai was even more guilty, he regretted that he should not send a message to Gu Bai, and he should carry it to the death.

But it’s too late to say anything.

“Go quickly, go directly Gu Bai.” Wu Hai prayed in his heart.

And yet….

Gu Bai did not leave.

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

Can.. This is what I wrote, and I typed it word by word.

After a pause, Gu Bai recalled the content of the paper and said lightly: “‘Laplace transform’, like ‘Fourier analysis’, is a kind of integral transformation commonly used in engineering mathematics, but compared with the reductionist and analytical characteristics of ‘Fourier analysis’, the Laplace transform is a linear transformation that converts a function with a parameter real number t(t≥0) into a function with a complex number s, so it is more widely used…”

“… The paper I wrote used the initial solution of the inverted stochastic differential equation, that is, using the equation F(s) = ∫∞0_f(t)?? -tdt transforms a function in one time domain to the convergence factor of a complex function in the complex frequency domain…”

Gu Bai told all the exposition processes of this paper, as well as the logical ideas.

His voice wasn’t loud, but… But it reached everyone’s ears.

This moment.

Whole.. The senior mathematics students of Ladder Professor 201 all looked at Gu Bai on the stage with a blank expression.

What is he talking about, is it Chinese?

Oh, yes.

But why can’t I understand?

Only Professor Luo Shifei, who was standing on the stage, calmly raised his eyes, thinking that this paper that was fully qualified to be submitted to SCI Weekly would not really be written by this kid.

However, how is this possible?

Freshman year, he’s only freshman!

What were you doing yourself in your freshman year?

Dreging? That’s not true, but: When he was a freshman, he Luo Shifei was definitely not comparable to the young man in front of him, and even those professors in Qingbei were definitely not comparable to the young man in front of him.

This paper qualified to be submitted to SCI, Luo Shifei has certainly read it, and he is very careful.

Aside from some minor flaws, this paper can not find any faults in the calculation process, proof logic, and mathematical application, and even some Math Weekly editors will directly pass the review.

Are freshmen so rolled up now?

Is this what a freshman should do?
