Chapter 416 of “Complete Collection of Mathematics” is published!
“Okay, everyone, just concentrate and ignore those old people outside.”

Xu Qingshan spoke up to remind the students who were sitting down.

The bunch of old men outside the door were still peeking in, so Xu Qingshan could only ignore them all and started his first class.

“You don’t have to take out your textbooks yet. What I’m going to talk about in this class is not in the textbook, and this version of the textbook is a little different from what I arranged.”

Xu Qingshan didn’t even turn on the computer, he just patted the blackboard behind him.

The students who were about to take out their books looked at each other, put their books back and took out their notebooks.

Xu Qingshan wrote the word “number theory” heavily on the blackboard behind him with satisfaction.

He turned around, put his hands on the desk, and asked the students first.

“Before learning number theory, please tell me, what is number theory in your mind?”

Xu Qingshan randomly called on a few students who raised their hands.

“A numbers game.”

“It looks a bit boring, but it should look awesome.”

“Something I don’t understand.”

This group of students were quite active. They raised their hands more frequently than each other, but their answers were more ridiculous than each other.

Xu Qingshan smiled, asked the last student to sit down, and continued speaking.

“In fact, if you really want to talk about it, number theory itself doesn’t seem to be very useful. But let’s not discuss the definition of useful and useless here.”

Xu Qingshan raised his hand and began to tell a story.

“As early as 1940, when the Battle of Britain broke out over the English Channel, Mr. Godfrey Hardy, who was still in Cambridge at the time, published an article on mathematics called “A Mathematician’s Apology.” In this article, Mr. Hardy said that the proudest thing about his life was that he had never done anything useful.”

“And mathematics is what he did his whole life.”

“From that time on, there was a view in the mathematical community that real mathematics was useless, artistic, and beautiful, while useful mathematics was mundane and boring.”

“But in fact, Mr. Dai’s favorite number theory, which he considered the most useless pure mathematical aesthetics, has been deeply applied to cryptographic systems that can control nuclear missiles more than 40 years later and has become the most important theoretical basis of public key cryptography.”

“So when we study prime numbers, we are not only fighting for the beauty of mathematics, we are also fighting for the future.”

Xu Qingshan smiled and wrote the word “prime number” behind him.

“When everyone first got to know me, I think it was when I solved the twin prime conjecture, but today we will definitely not talk about something that complicated. We will first talk about prime numbers.”

“Prime numbers are actually very interesting. They are like lone rangers in the mathematical world, like lone wolves living alone. No one can divide them except 1 and themselves.”

“You may be wondering, is 1 a prime number? Those who have prepared in advance should know that 1 is called a unit number. But it was not a unit number at the beginning because many top mathematicians argued over this issue and even overturned the table during the discussion, but they could not reach a consensus in the end.”

“There was nothing we could do. After everyone finished discussing it, they simply kicked him out of the group chat and changed it to calling him in single digits.”

Xu Qingshan spoke very easily and his story easily attracted the students in the audience.

Although his lecture did not contain any deep mathematical thinking, the group of senior students watching outside stared at each other with wide eyes, as if to say, “You are a Fields Medal winner, and this is what you are teaching us in your first class?”

This is not a kindergarten car, this is a prenatal education car!
However, while the teachers were listening with envy, the students in the room were listening very attentively.

These Peking University students were already very excited to be able to choose Xu Qingshan’s course. Many of them had already taught themselves number theory in advance and were looking forward to performing well in Xu Qingshan’s class.

But unexpectedly, as soon as the class started, Xu Qingshan asked them to put away their books.

Then it turned into a story lesson.

However, Xu Qingshan’s identity and status are there, so even if he tells everyone stories and jokes, these students will calm down and listen patiently and constantly recall the truth that Xu Qingshan wants to tell them in the stories.

After the class, Xu Qingshan felt relaxed and comfortable.

When the bell rang for the end of get out of class, Xu Qingshan licked his lips with satisfaction.

“Okay, the first class today ends here. The class committee members of each class please add my QQ number. Before the next class, I will let you pick up the class materials.”

To teach this group of young men, Xu Qingshan would definitely want to use his own books.

Although the “Complete Book of Mathematics” has not been fully written yet, he has already completed the number theory part. It is perfect to select the introductory part and use it as a teaching material for these students.

This is Capital University.

Xu Qingshan does not have any teaching indicators. He does not even need to care about the pass rate or excellence rate of these students.

He just needs to teach these students.

Of course, this step alone is enough to cause headaches for many university professors, because it not only involves their teaching ability, but also involves the students’ subjective initiative.

No matter how well you lecture or how brilliantly you teach, it will be useless if students don’t want to listen.

Fortunately, Xu Qingshan has an advantage in teaching courses, that is, the number of seats in the class is limited, and the students who can grab his course are almost all those who are interested in in-depth research in number theory itself.

The reason why I used “almost” instead of “all” is because there are indeed some students mixed in here who are here purely for Xu Qingshan.

Of course, such students have a stronger passion for learning.

They were eager to perform better in class, do their best on their homework, and then get the opportunity to be praised by Xu Qingshan and leave a deep impression.

Xu Qingshan’s second class came not too late, just one day later.

These students, who were still immersed in the previous story class, immediately felt the malice from the youngest Fields Medal winner in history.

“Mom, save me! Open the door quickly, this is not the car to the kindergarten.”

“Oh my god, the last class was so relaxing, and this one is like a freeway race.”

“Stop yelling. Although this class is very strenuous and difficult, I feel like I have really learned it.”

“I suspect the teacher is stuck at the limit of what we can absorb and keeps pulling us back.”

Xu Qingshan grinned when the get out of class was over, and strode out of the classroom with his materials. The students in the classroom, who had been tense, instantly relaxed at this moment and began to complain to each other.

“But you really shouldn’t tell me. Although I am really tired, I always have the urge to go back to the dormitory and continue my research.”

“You guys are so ungrateful for what you have. I think I have the worst talent in this class, but I still managed to keep up.”

“Look at Luo Shen sitting in the first row. He is still writing.”

Two classes of time.

These students have already completely determined their goals.

They all want to study hard and work hard, and then strive to be admitted to Xu Qingshan’s experimental team. Those who have not listened to Xu Qingshan’s class cannot feel Xu Qingshan’s charm at all.

Some students have even started planning their postgraduate studies two or three years in advance. Although Beijing University has many guaranteed places for postgraduate studies.

But this does not mean that they can join Xu Qingshan’s team just by being admitted to graduate school at Beijing University.

Because there are still students who have been guaranteed admission to graduate school from all over the country who are eyeing the opportunity, and the number of students that Xu Qingshan’s team can recruit each year is limited. They must really work hard to get in, while the number of places for postgraduate entrance examination students that will inevitably be opened up.

Therefore, many people are making several plans in their minds. If they fail to get Xu Qingshan’s admission promise when they are admitted to graduate school, they may still stubbornly give up the admission and choose to fight for it again by taking the postgraduate entrance examination.

Of course, those who can make such a decision in their hearts are generally the best in Kyoto University and have absolute confidence.

It’s just that any passerby picked out from Beijing University is a unique young genius in his city.

Xu Qingshan naturally didn’t know that he had only taught two classes, but the students in the audience were already agitated. He returned to his office and asked Wang Wei to help him print out the new materials that the students would use and put them in the reception room on the first floor.

He has already notified the student committee members to come to his laboratory tomorrow morning to collect the new information.

Anyway, Xu Qingshan didn’t have the complete book, so he just printed it out for the students in parts.

Xu Qingshan had just finished making arrangements when Zhou Qifeng came over following the smell.

“Qingshan, I heard that you printed out the textbooks you used in class today?”

Xu Qingshan nodded without even raising his eyes.

“Did you print them the number theory section of the Complete Book of Mathematics?”

Zhou Qifeng smiled and rubbed his hands.

Xu Qingshan looked up at Lao Deng in front of him and curled his lips.

“Old Zhou, you are asking questions even though you already know the answer. You came to me with a copy in your hand and asked me, “You’ve already read the book, so why can’t I use it in class?”

“No way.”

Zhou Qifeng put down the copy in his hand, sat down, and placed the briefcase he brought on Xu Qingshan’s desk, interrupting his work.

“I have good news for you. You won’t have to make copies starting tomorrow. Take a look at this.”

Zhou Qifeng took out a large book from his briefcase. It was not too thick, about the size of an A4 paper, and handed it to Xu Qingshan.

The main element of this book is black, with four large white characters written on the cover.

The Complete Book of Mathematics

And the subtitle below it reads “—— Part One: Number Theory”.

The cover design of the whole book is simple and elegant, which is very consistent with Xu Qingshan’s aesthetic.

“This is a sample designed by the publishing house. Just flip through it and see if there is anything that needs to be changed.”

Zhou Qifeng was very happy.

It was good to have Xu Qingshan. All of these were his achievements. If I spent my time on others, I wouldn’t necessarily gain anything. But with Xu Qingshan, there were almost continuous rewards.

“It’s printed out so quickly? Let me take a look.”

Xu Qingshan remembered that it had only been a month since Zhou Qifeng and others took away the photocopied manuscript of the number theory article.

You should know that the publishing process of academic monographs is quite long.

Normally, the publishing of academic monographs is completely different from that of popular reading materials. The publishing models of monographs are divided into public publishing and self-funded publishing.

Publicly funded publishing is relatively rare, as the expenses are borne by the publishing house. This requires academic monographs with strong market profit potential for publishing houses to be willing to take a chance.

The mainstream is self-publishing, with the author bearing all the expenses. Of course, publishing expenses reimbursed through scientific research project funds are also counted as self-publishing.

This is actually quite normal, because just by looking at the name of the academic monograph, you can tell that it only applies to the vertical market field, and the audience itself is already pitifully small, so it is extremely difficult to make a profit.

Generally speaking, only those versions that have been clearly designated as national textbooks during the writing stage can be published at public expense.

Moreover, the print run of academic monographs is generally relatively small.

But Xu Qingshan was different. When Zhou Qifeng took it, he had already said that Capital University would bear all the expenses, and it was made by Capital University Press. No matter whether it was revenue, production, or design, every aspect was the best.

But even if the speed is faster, the general publishing cycle takes at least 4 months.

Even if the process is the fastest and simplest, it still needs to go through three reviews and three proofreadings. The initial review is to check the format and specifications, the re-review is for academic quality, and the final review is to clarify the corresponding political and legal regulations.

In the formal publishing market, any content involving ethnicity, religion, party history, etc. requires special filing and special case review. Special monographs such as medical and biological monographs also need to pass ethical review.

After passing the review, the publishing house also needs to go to the official website of the General Administration of Press and Publication to register and complete the CIP data verification.

Only at this step can you start designing the layout and making sample books.

But now Zhou Qifeng was holding the finished book in front of him, which meant that many of the processes were quickly skipped by them using special channels.

“Of course we have to handle your matter as quickly as possible. If you think there is no problem with this design, our school’s publishing house will be able to publish this batch next month.”

“If you find it troublesome to print materials for your classes, the first batch of books will be transferred to your students for use first.”

Zhou Qifeng waved his hand.

“So good? Will it really be sold?”

Xu Qingshan shook the beautifully crafted book in his hand.

“Can’t sell it?”

Zhou Qifeng raised his eyebrows.

“I think you don’t understand. Do you know how many schools have come to me for reservations?”

Zhou Qifeng stretched out two fingers and gestured twice.

“I just had someone submit the application form for the book number for your book The Complete Book of Mathematics, and many people have heard about it and have come to me privately to see the sample.”

“After the manuscript is printed, we will have received pre-order intentions. Of course, we cannot sign a contract now that the book is not out.”

“22 families.”

“A total of 22 985 universities that were able to receive the news in advance have come to us to place orders for books.”

“Do you know what this means?”

Zhou Qifeng was delighted.
