Chapter 9 I'm Afraid I Went to a Fake University

The Q&A room was full.

The juniors and seniors who are interested in the postgraduate entrance examination are burying their heads and concentrating on reviewing.

Sitting next to the desk is Professor Tang Zhiwei of the Department of Mathematics of Jinda University. He saw that he had put down the newspaper in his hand and was meticulously staring at the title on the scratch paper. The fingers of his right hand turned the cap of the pen back and forth.

Lu Zhou, who was standing beside him, knew very well that this small action meant that he was lost in thought.

"...Where did you get the question from?" After staring at the formula on the scratch paper for a long time, Tang Zhiwei suddenly asked.

"The reference book mentions the Fourier coefficient, so I went to the library to check the relevant information, and found that there are several variants of the Fourier inversion theorem, as well as several variants. Application, I tried to deduce it, and found that I couldn't solve it at this step." Lu Zhou smiled embarrassedly, with a look of trouble on your face.

Tang Zhiwei glanced at Lu Zhou and continued to turn his attention to the scratch paper. This time he put down the cap of the pen, picked up the chalk, walked to the blackboard for a while, and reached out to start a draft on the blackboard.

Lu Zhou stared intently at the blackboard, perhaps because he had done his homework in advance, he found that he could keep up with the teacher's rhythm unexpectedly.

Attracted by the swishing sound of chalk on the podium, the juniors and seniors, who were sitting below reviewing advanced math, raised their heads from time to time, staring blankly at the calculations written on the blackboard, and then quickly turned their heads. buried.

emmm...

What the hell is this written about?

Time passed minute by minute, and before you knew it, the entire blackboard was filled with writing.

From the upper left corner of the blackboard to the lower right corner of the blackboard, Tang Zhiwei stopped writing, turned around, looked at Lu Zhou and asked, "Do you understand this part?"

Lu Zhou, who was staring at the blackboard seriously, nodded: "Understood."

Tang Zhiwei raised his eyebrows and asked, "Do you really understand what is fake?"

Lu Zhou said: "I really understand."

Tang Zhiwei didn't speak, picked up the blackboard eraser, wiped off the things on the blackboard, picked up the chalk and continued writing the next step on the blackboard, but the evaluation of Lu Zhou in his heart dropped by half a point.

He hated two kinds of students in his life. One was the one who gave him gifts to ask him to change his grades, and the other one was the one who pretended to ask him for advice in front of him with a question beyond the outline.

Especially the latter, it is purely a waste of his time!

Obviously not interested in mathematics, but also pretending to be a researcher, it is disgusting to look at! This kind of person just wants to be close to the teacher all day long, and he has no idea what he is studying for at all.

At the end of the writing, there are still a few lines of steps left to write. Professor Tang Zhiwei suddenly stopped, looked back at Lu Zhou, and suddenly smiled and said, "I've come to this point, you should understand?"

Lu Zhou nodded: "Understood...Thank you teacher!"

Chen Yushan, who was sitting in the corner of the first row reviewing advanced mathematics, has been secretly watching the two people on the podium, listening to the two people's constant "Understand?" "Understand." .

What do you understand?

What are they talking about?

Realizing that she couldn't understand their conversation at all, Chen Yushan despaired of her mathematics.

Could it be... that I'm actually a scumbag?

Hearing Lu Zhou's answer, Tang Zhiwei smiled, put the chalk lightly on the lecture table, went back to the chair and sat down, picked up the thermos and sipped a sip of tea, and said slowly: "Do you understand? Then you Come and write the rest of the steps for me."

You know the shit!

When I write, I stand there like a second fool, without even taking a note. If you can understand this, I will eat this cup!

Looking at Professor Tang Zhiwei's expression, Lu Zhou immediately understood that the professor suspected that he didn't listen at all and was testing himself!

Thinking of this, Lu Zhou couldn't help crying and laughing.

Heaven and earth conscience, I really understand!

He didn't know why. When Professor Tang was doing calculations on the blackboard, the formulas seemed so familiar to him.

Is it because the knowledge of system points exchange covers this part of the knowledge? Or is it because your math experience value has increased, which has improved your sense of math?

Anyway, he really understood.

Lu Zhou didn't know the specific reason, but it was obviously not the time to think about it. Professor Tang was still there waiting for him to perform. In order to publish the paper in a logical way next semester, he couldn't make mistakes at this juncture.

I saw Lu Zhou smiled confidently, picked up the chalk and walked to the blackboard.

Professor Tang's eyebrows jumped, thinking that this kid can't really write the rest of the steps, right?

impossible.

Absolutely impossible!

Even if he has completed most of the proof process, the remaining few lines of calculation are definitely not something a freshman can do! Even those graduate students he brought, had to ponder his proof process several times from beginning to end before they could figure out the way!

And this guy, but when he was listening, he didn't even take notes!

Time passed by, and the surprise in Professor Tang's heart had turned into deep shock, and finally turned into praise.

All doubts are like the snow on the cornices in spring, melting the ice and snow at the moment when the sun shines.

When Lu Zhou wrote the last symbol on the blackboard, Professor Tang, who was staring at the blackboard, nodded approvingly: "Not bad...well written."

The solution of the last few steps is slightly different from his thinking, and it is a little more cumbersome, but it is also a novel idea. This shows that he not only listened to what he said, but also incorporated his own thinking into it.

And this is the most valuable.

It seems that he was wrong...

"Thanks to the teacher's guidance, if it was me, I would definitely not be able to count this step..." Lu Zhou smiled embarrassedly.

He didn't lie about this sentence. In the calculation steps given by the system, there are many places similar to "a=b", and he did not clearly tell him why the equal sign can be drawn between the two.

And what he asked Professor Tang for advice was the specific proof about this part.

"Don't be humble with me, I can see your level." After putting the lid on the thermos, Professor Tang continued to ask, "Which class are you from?"

"The freshman class, Lu Zhou." Lu Zhou answered truthfully.

"Lu Zhou..." Professor Tang nodded and recited it a few times, as if to remember the name.

It turns out that this senior is called Lu Zhou...

Chen Yushan, who was sitting in the corner eavesdropping, nodded suddenly, suddenly felt that something was wrong, and immediately reacted.

Big, freshman? !

Thinking of calling him senior for a long time, Chen Yushan's face turned red, her whole body was like an ostrich, her head slammed on the table.

It wasn't just Chen Yushan who was full of shock in their hearts. The seniors and seniors in the first row of the Q&A room also looked at this junior with a bewildered look, rushing through 10,000 alpacas in their hearts.

Are all freshmen now so good?

And let no one live!

"Are you going to take the high school entrance exam? How's your review going?"

"The review is almost done, I just want to read some extracurricular books." Lu Zhou smiled shyly.

"Heh, let you take the test, I'm afraid I will look down on you." Tang Zhiwei laughed and joked, "How about I give you a separate test?"

"Don't, teacher, people will die!" Lu Zhou couldn't tell whether to laugh or cry.

"Hmph, you can kill someone by doing a question? I don't believe it." Tang Zhiwei looked Lu Zhou up and down, and nodded approvingly, "Yes, very good, I rarely praise a student like that. If it wasn't for you, Freshman year, I really want to say hello to the people from the Academic Affairs Office and transfer you to my office for research."

"Teacher, you have lifted me up. I still have a lot to learn. If I really want to do research with you, it must be a hindrance for you." Lu Zhou knew that Professor Tang was joking, so he said modestly.

Tang Zhiwei snorted and criticized: "Hmph, don't come to me with those polite words, and those who are scholarly should be well-educated, and don't always put those scenes in your stomach."

Although he was criticized inexplicably, Lu Zhou knew that Professor Tang was not really angry, but really regarded himself as his student and taught himself.

The old gentleman was definitely smiling when he was angry. For example, when he was writing on the blackboard just now, when he mistakenly thought that he was pretending to do fake knowledge there, he would definitely be angry.

"The teacher is right, I know."

Seeing the sincere expression on Lu Zhou's face, Tang Zhiwei nodded, softened his tone a bit, and continued: "It's a good thing to be interested in mathematics, I hope you can continue to keep it. Also, the direction you chose is good, although it counts Not in any popular direction, but it is easy to get results. If you have a good idea, you can do it boldly. If you don't understand, you can read and ask more. This is how knowledge comes out. Something that can't be found."

After a pause, Professor Tang continued: "Although the mathematics department of our Jinda University is not very strong, the physics department still has nothing to say. In the application of Fourier transform, in spectrum analysis and data compression and orthogonal frequency The applications of multiplexing and multiplexing are quite extensive. If you make a difference in this area, I believe that when you are in your senior year, several professors in the Department of Physics next door will definitely be rushing for you."

Speaking of this, Professor Tang smiled and said, "Learn more, see more, practice more, and study more. I'll stop talking nonsense here. You can go and think about it yourself, and I won't waste your time."

"Thank you, Professor! Your words from the bottom of your heart, the students will keep in mind." Lu Zhou said sincerely.

"Don't talk about the scene, what did I tell you just now? Just say thank you if you want to. Hurry up when you're done. Do you want me to get up and see you off?" Tang Zhiwei scolded with a smile.

Lu Zhou smiled, turned around and walked out the door with the scratch paper and pen, and took the door of the answering room with him.

Looking back at the blackboard, Tang Zhiwei smacked his mouth and sighed, feeling full of emotion in his heart.

Jinling is indeed the ancient capital of the Six Dynasties, with outstanding people.

We, Jin Da, stand on this dragon vein, and it really is a talented person!

The undergraduates in the audience looked confused, looked at the dazzling formulas on the blackboard, and looked at their exercise book, with mixed feelings.

I'm afraid I went to a fake university...
