Scholar’s Advanced Technological System

Q & A room is full.

The senior junior and senior sisters who have aspiring to enter the postgraduate entrance examination are burying their heads intently to review.

At the desk, there was Tang Zhiwei, a professor of mathematics at Jinda University. At this moment, he had put down the newspaper in his hand, stared at the title on the draft paper meticulously, and flipped the lid of the pen back and forth with the fingers of his right hand.

Lu Zhou, who was standing next to him, knew very well that this small gesture meant that he was thinking.

"... where did you get the question?" Staring at the formula on the draft paper for a long time, Tang Zhiwei suddenly asked.

"Fourier coefficients are mentioned in the reference book, so I went to the library to check the relevant materials, and found that there are several variants of the Fourier inversion theorem mentioned in it, as well as several variants. Application, I tried this derivation, and found that this step could not be solved. "Lu Zhou smiled embarrassed, with a troubled expression on his face.

Tang Zhiwei glanced at Lu Zhou and turned his attention to the draft paper. This time, he lowered the pen cover, took the chalk, walked to the blackboard, paused, and reached for the draft on the blackboard.

Lu Lu stared intently at the blackboard, perhaps because he had done his homework beforehand, and found that he was unexpectedly able to keep up with the teacher.

The snoring of chalk on the podium attracted attention. The senior juniors and seniors who were sitting underneath to review the high numbers looked up from time to time, staring blankly at the formula on the blackboard, then quickly turned their heads again. Buried.

Emmm ...

的 What the **** is this?

The time passed by one minute and one second, and before I knew it, the entire blackboard was full.

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?"

舟 Lu Zhou, staring at the blackboard seriously, nodded: "I see."

Tang Zhiwei raised an eyebrow and asked, "Do you really understand?"

Lu Zhou said, "I really understand."

Tang Zhiwei didn't say anything. He picked up the blackboard eraser, wiped the things off the blackboard, picked up the chalk to continue the next step of the blackboard writing, but the evaluation of Lu Zhou in his heart fell by half.

He hated two kinds of students the most in his life. One was to give him gifts to ask him to change points, and the other was to ask him for a question in front of him.

Especially the latter, wasting his time!

Tong Mingming is not interested in mathematics, but he must also show that he is very researched and looks disgusting! This kind of person just wants to be close to the teacher all day long, but he hasn't figured out exactly what he is learning for.

After writing to the end, there are a few lines of steps left. Professor Tang Zhiwei suddenly stopped, looked back at Lu Zhou, and suddenly smiled and said, "I have reached this step, you should understand?"

Lu Zhou nodded: "I see ... Thank you teacher!"

Sitting at the corner of the first row to review the high numbers, Chen Yushan has been secretly watching the two on the podium, listening to the communication between the two "understood?" And "understood." .

What do you understand?

到底 What are they communicating with?

Realizing that she could not understand their conversation at all, Chen Yushan was desperate for her mathematics.

Isn't that ... I'm actually a scum?

After hearing Lu Zhou's answer, Tang Zhiwei smiled, put the chalk lightly on the desk, returned to the chair, sat down, picked up the thermos and sipped tea, and said slowly: "Really understand? Then you Come and write the rest of the steps for me. "

You know what a fart!

Lao Tzu was standing there like a second fool when writing, not even taking a note. If you can understand it, I will eat this cup!

At first glance at Professor Tang Zhiwei's expression, Lu Zhou understood instantly. The professor suspected that he hadn't heard it at all and was testing himself!

I thought of this, Lu Zhou couldn't help crying.

Conscience, I really understand!

He didn't know why. When Professor Tang calculated on the blackboard, the formulas seemed so familiar to him. I always felt that I had seen them, but I couldn't tell where.

Is it because the knowledge of system points conversion covers this part of knowledge? Or is it because your own experience in mathematics has increased and you have improved your feelings about mathematics?

In short, he did understand.

Lu Zhou didn't know the specific reason, but now obviously he is not thinking about this time. Professor Tang is still waiting there for him to perform. In order to be able to publish the thesis in a logical way next semester, he can't make a mistake in this section.

I saw Lu Zhou smile with confidence, picked up chalk and walked to the blackboard.

Professor Tong Tang's eyebrows jumped, and he said that this kid would not really be able to write the remaining steps?

Impossible.

Absolutely impossible!

Even if he has completed most of the proof process, the calculation of the remaining lines of calculations is definitely not something a freshman undergraduate can do! Even the graduate students he brought, he had to ponder his certification process several times from beginning to end to figure out the way!

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

The time passed by minute by minute. The surprise in Professor Tang's heart has become a deep shock, and finally a praise.

All doubts are like snow on the spring eaves, and the snow melts at the moment when the sun is shining.

When Lu Zhou wrote the last symbol on the blackboard, Professor Tang, who was staring at the blackboard intently, nodded approvingly: "Yes ... well written."

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

This is the most precious thing.

I seem to blame him ...

"Thanks to the teacher's guidance, if I were to do this, I wouldn't have done this step ..." Lu Zhou smiled embarrassedly.

He didn't lie about this sentence. In the calculation steps given by the system, a lot of things like "a = b" didn't tell him clearly why the equal sign could be drawn between the two.

And what he asked Professor Tang for is the specific proof of this part.

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

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

"Lu Zhou ..." Professor Tang nodded and meditated several times, as if to remember the name.

It turns out that the senior is Lu Zhou ...

Chen Yushan, who was eavesdropping in the corner, nodded suddenly, suddenly feeling something was wrong, and then reacted.

Big, freshman? !!

I thought of calling him a longtime senior, Chen Yushan's face turned red, and the whole person was like an ostrich, his head was on the table.

It wasn't just Chen Yushan who was full of shock in his heart. The senior juniors and seniors in the first row of the Q & A room also looked at the student with a grimace and ran 10,000 alpacas in his heart.

Is the freshman so fresh now?

It makes people not live!

"Are you going to take the senior exam? How is the review?"

"I'm almost done reviewing, so I want to read some extra-curricular books." Lu Zhou smiled wryly.

"Oh, let you test that paper, I'm afraid I despised you a little bit." Tang Zhiwei laughed and joked, "Will I make a separate paper for you to do?"

"Don't be a teacher, it will be dead!" Lu Zhou couldn't say without crying.

"Huh, can you still be dead? I don't believe it." Tang Zhiwei glanced up and down and nodded approvingly, "Yes, very good, I rarely praise such a student so much. It was not for you As a freshman, I really want to say hello to the people at the Academic Office and transfer you to my office for research. "

"Teacher, you have elevated me. I still have a lot to learn. I really want to do research with you. It must be a hindrance for you." Lu Zhou knew modestly that Professor Tang was joking.

Tang Zhiwei snorted and criticized, "Hum, less come with those polite words, and those who are academics do their studies well, don't always put those scenes in your stomach."

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

When the old gentleman was angry, it was definitely smiling. For example, when he was writing on the blackboard just now, he must have been furious when he mistakenly assumed that he was pretending to be a fake learner there.

"The teacher is right, I know."

Seeing the earnest expression on the landing boat, Tang Zhiwei nodded, his tone eased a bit ~ www.wuxiaspot.com ~ went on to say: "It's a good thing to be interested in mathematics. I hope you can keep it. And you choose The direction is good, although it is not a popular direction, but it is easy to get results. If you have any good ideas, do it boldly. If you do n’t understand, just look at it and ask more. Learning is just like this. You will find things that others cannot find. "

After a pause, Professor Tang continued, "Although our math department at Jinda University is not that strong, the physics department still has nothing to say. In the application of Fourier transform, spectrum analysis and data compression, and orthogonal frequency The applications in these areas of multiplexing are still quite extensive. If you make a difference in this area, I believe that by the time you are in your senior year, several professors in the Department of Physics next to us must be eager for you. "

Speaking of this, Professor Tang smiled and said, "Learn more, watch more, practice more, study more. I'll stop here to talk nonsense, you go on thinking about it yourself, and I will not delay your time."

"Thank you, Professor! Your students have the heart in mind," Lu Zhou said sincerely.

"Don't you tell me some scenes, I just told you just now? Just want to thank me for saying thank you. After finishing speaking, hurry up and ask me to get you off?" Tang Zhiwei laughed and cursed.

Lu Zhou grinned, turned to the door with draft paper and pen, and brought the door of the answering room.

I looked back at the blackboard, Tang Zhiwei smashed his mouth, sighed, and kept feeling sigh.

Jinling is truly an ancient capital of the Six Dynasties.

Our Jinda is standing on this dragon vein, really talented!

The undergraduates on the stage looked aggressive, looked at the dazzling calculations on the blackboard, and looked at their exercise book, which was full of whimsy.

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