Scholar’s Advanced Technological System

The answering room is full of seats.

The juniors who are interested in the postgraduate study are concentrating on reviewing.

Sitting next to the desk, Tang Zhiwei, a professor of mathematics at Jinda University, saw that he had put down his newspaper at the moment and was staring at the topic on the draft paper with meticulous attention. The fingers of his right hand flipped the pen cover of the pen.

Standing on the side of Lu Zhou is very clear, this little action means that he is trapped in thinking.

"...what did you get from?" Staring at the calculations on the draft paper for a long time, Tang Zhiwei suddenly asked.

“The reference to the Fourier coefficient is mentioned in the reference book. I went to the library and looked up the relevant information. I found that there are several variants about the Fourier inversion theorem, as well as several variants. Application, I tried this derivation, and found that this step can not be solved." Lu Zhou embarrassed smile, a look of trouble with your expression.

Tang Zhiwei looked at Lu Zhou and his eyes continued to turn to the draft paper. This time he put down the pen cover and picked up the chalk. He walked over to the blackboard and reached for a draft on the blackboard.

Lu Zhou stared at the blackboard intently, perhaps because he had done this in advance, he found that he could keep up with the rhythm of the teacher.

The chalk squeak on the podium attracted attention. Sitting on the top of the junior high school seniors who studied the high numbers, they looked up from time to time, looked at the calculations on the blackboard on the blackboard, and then quickly turned their heads. Buried down.

Emmm...

What do you write about this?

Time passed by, and the entire blackboard was filled up unconsciously.

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

Seriously staring at the blackboard, Lu Zhou nodded: "Understood."

Tang Zhiwei’s eyebrows were picked and asked: “Do you really understand?”

Lu Zhou said: "I really understand."

Tang Zhiwei did not speak, picked up the blackboard eraser, wiped off the things on the blackboard, picked up the chalk and continued the book next, and the evaluation of Lu Zhou in his heart was a half point.

He hates two kinds of students in his life. One is to ask for a change in his gift, and the other is to ask for a super-topic in front of him.

Especially the latter is pure waste of his time!

Obviously not interested in mathematics, but also to show their own research, look disgusting! This kind of person only wants to be close to the teacher all day long. He hasn’t figured out what he is learning for.

At the end of the writing, there were still a few lines left to write. Professor Tang Zhiwei suddenly stopped and looked back at Lu Zhou. He suddenly said with a smile: "I have calculated this step, should you understand?"

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

Sitting in the first row of corners to review the high number of Chen Yushan, has been secretly watching the two men on the podium, listening to the two people's "I don't understand?" "Understanding." The exchange is full of fog .

What did you understand?

What are they talking about?

Realizing that they could not understand their dialogue, Chen Yushan felt desperate about her mathematics.

Is it... I am actually a student?

Hearing Lu Zhou’s answer, Tang Zhiwei smiled and put the chalk on the desk, went back to the chair and sat down, picked up the thermos and drank the tea, and said slowly: “Do you understand? Then you Come and finish the rest of the steps for me."

You know a fart!

When I wrote it, I stood there like a idiot. I didn’t even do a single note. If you can understand this, I will eat this cup!

A look at Professor Tang Zhiwei's expression, Lu Zhou immediately understood, the professor is skeptical that he did not listen to it, test himself!

Thinking of this, Lu Zhou was crying and laughing.

Heaven and earth conscience, I really understand!

He didn't know why, when Professor Tang was calculating on the blackboard, the formula of that article was so familiar in his eyes. He always felt that he had seen it before, but couldn't tell where it was?

Is it because the knowledge of system point redemption covers this part of the knowledge point? Or is it because of the increase in the value of his own mathematics experience that he has improved his feelings about mathematics?

In short, he did understand it.

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

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

Professor Tang’s eyebrows jumped and he said that this kid wouldn’t really write the rest of the steps?

impossible.

Absolutely impossible!

Even if he has completed most of the proof process, the calculations of the remaining lines can never be completed by a freshman undergraduate! It is the graduate students he brought, and he has to repeat his proof process several times from beginning to end to understand the doorway!

And this guy, but when listening to the lecture, even the notes are not done!

Time passed by, and the strangeness in Professor Tang’s heart has turned into a deep shock and eventually turned into praise.

All the suspicions are like the snow on the spring, and the snow melts at the moment of the sun.

When Lu Zhou wrote the last symbol on the blackboard, Professor Tang, who stared at the blackboard, nodded his approval: "Not bad... well written."

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

And this is the most valuable and valuable.

It seems that he is wrong with him...

"Thanks to the teacher's advice, if it is my own, it is definitely not this step..." Lu Zhou smiled embarrassedly.

In this sentence, he did not lie. In the calculation steps given by the system, many places similar to "a=b" did not explicitly tell him why the two could be drawn equal.

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

"Don't be modest with me, I can see your level," covered the lid of the thermos. Professor Tang continued to ask, "Which class do you have?"

"A big class, Lu Zhou." Lu Zhou answered truthfully.

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

It turned out that the schoolmaster called Lu Zhou...

Chen Yushan, who was sitting in the corner and secretly nodded, suddenly felt that something was wrong, and then he reacted.

Big, freshman? !

Thinking of calling him a half-day senior, Chen Yushan’s face was red, and the whole person was like an ostrich, and his head was on the table.

The heart is full of shocks not only Chen Yushan, but also a few junior high school seniors in the first row of the question room. They also looked at the school brother with a look of enthusiasm, and rushed over 10,000 alpaca.

Are the freshmen nowadays so arrogant?

Also let no one live!

"Want to test the high generation? How about reviewing?"

"The review is almost the same, I want to see some extracurricular books." Lu Zhou smiled.

"Oh, let you test the paper, I am afraid that it is a little bit of you." Tang Zhiwei laughed and joked, "Would you like me to give you a separate paper?"

"Don't be a teacher, it will be dead!" Lu Zhou couldn't help but laugh.

"Hey, can you still be a dead person? I don't believe it." Tang Zhiwei looked up and down a few times, and nodded with approval. "Good, very good, I rarely praise a student. If you don't see you." Freshman, I really want to say hello to the people in the office, and transfer you to my office for research."

"Teacher, you have lifted me up. I still need to learn more things. I really want to do research with you. It is definitely dragging your hind legs." Lu Zhou knew that Professor Tang was joking and said modestly.

Tang Zhiwei snorted and criticized: "Hey, let me come to those who have a lot of words, and the people who do the study will learn well. Don't always put those scenes in your stomach."

Although inexplicably criticized, Lu Zhou knows that Professor Tang is not really angry, but truly regards himself as his student and teaches himself.

When the old gentleman was angry, it was definitely a smile. For example, when I was on the blackboard, I thought that when I was pretending to do fake teaching, he would definitely not be angry.

"The teacher is right, I know."

Looking at Lu Zhou’s sincere expression, Tang Zhiwei nodded and relaxed his tone. He continued: “It’s a good thing to be interested in mathematics. I hope you can continue to keep going. Also, you choose the right direction, although It's not a hot direction, but it's easy to produce results. If you have any good ideas, you can do it boldly. If you don't understand, you should read more questions. Learning is like this. If you don't know, you can find someone else. Things that can't be found."

After a pause, Professor Tang continued: "The mathematics department of Jinda is not strong, but the physics department still has nothing to say. In the application of Fourier transform, in spectrum analysis and data compression and orthogonal frequency The application of sub-multiplexing is still quite extensive. If you make a difference in this area, I believe that when you are a senior, several professors in the physics department next door will definitely want you."

Speaking of this, Professor Tang smiled and said: "Learning more, seeing more, practicing more, and studying more. I will talk about nonsense here, and you will continue to ponder and ponder, I will not delay your time."

"Thank you Professor! Your words are in your heart, and students keep in mind." Lu Zhou said with a sincere heart.

"Don't you talk about some scenes, I just told you about it? I want to thank you for saying thank you. I will hurry and finish, let me get up and send you?" Tang Zhiwei smiled.

Lu Zhouxiao smiled and turned the paper out with the draft paper and pen. He also took the door of the answering room.

Looking back at the blackboard, Tang Zhiwei sighed and sighed, and felt a sense of emotion in his heart.

Jinling is not the ancient capital of the Six Dynasties.

咱金大 stood on this dragon vein, it really is a talented person!

The undergraduate students in the audience looked awkward, looked at the dazzling calculations on the blackboard, and looked at their own exercise books.

I am afraid I have read a fake university...
