I really just want to be a scholar

Chapter 589 Professor Qin Ke and Professor Ning Qingyun's first class
Today is September 9th, Tuesday, Qin Ke got up early in the morning, practiced the Oriental Secret Code with Ning Qingyun, and after having breakfast together, he returned to the boys' dormitory and changed into a more formal suit.

It was just around 8 o'clock in the morning, and the little chubby Jiang Zhenjie just jumped out of bed yawning, and his eyes widened when he saw Qin Ke in formal attire: "Brother Ke, you are dressed so formally, are you going to get engaged?"

Facing the mirror, Qin Ke simply straightened his collar, combed his hair casually, and said with a smile, "I don't want to get engaged now, and I'll just get a marriage certificate in two years. I'm planning to go to the Qiuzhen Academy for classes." .”

Jiang Zhenjie just woke up and was still a little confused: "Oh, class... Brother Ke, what class do you still go to Qiuzhen Academy? Which teacher can guide you in mathematics? Mr. Qiu personally guides you?"

But Hua Manting, who had already woken up and was chatting on WeChat with his girlfriend Gan Peixuan, remembered, and raised his head and said, "Brother Ke, are you going to teach the students of Qiuzhen Academy? Brother Ke and the school committee are researchers in the Department of Mathematics. Qiuzhen Academy is a specially appointed professor of mathematics, responsible for algebra, geometry, mathematical analysis and number theory, didn’t the school’s official website issue a notice before?”

Jiang Zhenjie just patted his forehead, laughed and said: "Look at my memory, I saw Brother Ke every day, and thought I was still in the basic science class together, and then I remembered that Brother Ke and the school committee are already full professors... Hey, I I decided to talk to my girlfriend about an idea, and it happened that she was going to create a comic called "My Professor's Roommate Is Sassy and Handsome", and it would definitely be very popular."

This joke immediately made dormitory 501 burst into laughter, and even Li Xiangxue, who was reading next to him, smiled.

He got up and looked at Qin Ke: "Brother Ke, can I also go to your class."

Qin Ke knew that the little brother worshiped him, so he patted him on the shoulder and said with a smile, "Go if you want. Anyway, Qiuzhen Academy doesn't restrict listening, but you'd better bring your own stool, otherwise you might not be able to get a seat."

Li Xiangxue scratched his head, grabbed a coat and put it on, and then actually picked up his chair.

Qin Ke couldn't help laughing, grabbed the chair and put it down, pulled his arm and walked out: "Let's go, my brother is going to attend my class, and he has to bring his own stool. That's a big joke."

Arriving downstairs in the girls' dormitory, Ning Qingyun, who was dressed appropriately, just came downstairs and came to the door.

A pure white top with a large lapel, a big black bow tie on the chest, and a pair of loose jeans. It is dignified and elegant without losing youthful vitality. It looks like a professional white-collar worker, but it has a strong student atmosphere. It is very suitable for Ning Qingyun, whose appearance and figure have hardly changed with the times, is youthful and charming.

The girl obviously changed her clothes specially for the lecture, which caused many girls in the girls' dormitory to secretly look at her and study her outfits.

Although Ning Qingyun is not an art student, she has a natural sensitivity to beauty. It is not obvious when she usually wears low-key and simple clothes, but as long as she is a little more serious about matching clothes, she will immediately become the target of imitation by girls.

Even the boys who were waiting for their girlfriends downstairs in the girls' dormitory were stunned, but when they saw Qin Ke coming, they hurriedly either looked away or greeted Qin Ke warmly.

Probably only people like Li Xiangxue who only see problems and scientific research in their eyes can remain indifferent.

When Ning Qingyun saw Qin Ke brought Li Xiangxue out, he greeted Li Xiangxue unexpectedly, then stretched out his hand to straighten Qin Ke's clothes, smoothed some creases with his small hands, and sprayed on Qin Ke's combed hair Put on a setting spray and tidy up carefully.

"Okay. This looks a bit like a professor." Ning Qingyun put his hands behind his back, took two steps back, and looked at Qin Ke with satisfaction, looking very cute.

If it weren't for the students coming and going around, Qin Ke couldn't help but want to pinch her little face.

The three of them walked together and soon arrived at Qiuzhen Academy.Qiuzhen Academy is actually a major of "Mathematics and Applied Mathematics", but it is relatively independent of the Department of Mathematics, and implements the "3+2+3" continuous undergraduate, master, and doctoral training mode. Each session only recruits less than 100 students. The dean is Qiu Mr. Qiu, all the affairs inside, including the employment of teachers, are decided by Mr. Qiu. The goal is to cultivate a group of first-class talents who will lead the development of mathematics in the world according to Mr. Qiu's thinking.

Qin Ke and Ning Qingyun each have a 60-minute class on Tuesdays and Fridays every week. Qin Ke is mainly in charge of algebraic geometry and calculus (that is, mathematical analysis), and Ning Qingyun is in charge of the number theory part.

Regarding the teaching mode, Qin Ke and Mr. Qin also discussed with Mr. Qiu, and decided to imitate the relatively advanced international education system, and guide students to discuss while asking questions, so as to stimulate students' creative thinking.

In addition, Mr. Qiu also made a request, that is, to learn and communicate in English throughout the course, which is also the main language of the college's usual lectures.Because Mr. Qiu encourages students to communicate more with outstanding mathematics students of the same age at home and abroad, so as to realize the collision of different cultures and views, he usually pays attention to the cultivation of students' foreign language ability.

Qin Ke went to the first class first, Ning Qingjun sat down in the teaching assistant's seat in the front row, and Li Xiangxue found an empty seat to sit down by himself.

This is the largest West Lecture Room of Qiuzhen Academy, which can accommodate about 100 people. However, considering the teaching effect, the students are divided into two groups to attend class, one group on Tuesday and one group on Friday. Qin Ke has to teach the same content twice , but the advantage is that the number of students will be reduced to 50, which is convenient for communication, questioning and guiding thinking.

When Qin Ke walked to the podium, the students in the audience quickly quieted down, and everyone cast curious and admiring glances at their peers standing on the podium, especially when they saw that Qin Ke was empty-handed and even the textbooks were empty. When I didn't bring it, I couldn't hide my surprise.

Qin Ke stood still in front of the podium, looked around at everyone, and said in English with a smile: "Hi everyone, I am Qin Ke, I believe Dean Qiu has told you before, yes, starting today, I will be responsible for giving you weekly lectures. A big class on algebraic geometry and calculus."

In the audience are sophomores from Qiuzhen Academy. Basically, they have spent a year trying to catch up on English. It is not a problem to attend classes. The current classroom applauds like thunder. Everyone has heard the name of Qin Ke, a mathematical genius. Many people As soon as he entered school, he went to Room 501 of the boys' dormitory building to meet Qin Ke—of course, more people met Qin Ke at the school's commendation meeting.

Qin Ke pointed to Ning Qingyun again: "This is Ning Qingyun, who also gives you a big class every week. She is responsible for explaining the direction of number theory to everyone."

This time, the applause from the boys in the audience was even louder, with some kind of eagerness faintly revealing.

Not to mention Ning Qingyun's great reputation, at least there is such a beautiful girl of similar age standing on the stage to give lectures, it is also very eye-catching, right?
Qin Ke lightly pressed his hand, and the students quickly calmed down again.

Qin Ke smiled and said: "Thank you for your warm applause. I won't waste everyone's time now, and get to the point as soon as possible. After all, when I was in high school, I was most afraid of being talked about by the teacher-do you know that you are wasting everyone's life? Just Because you wasted 1 minute of class, the whole class was wasted 1 minute of life, adding up to 53 minutes! Are you worthy of others and the class?"

The students in the audience suddenly burst into laughter.Who hasn't been told that by a teacher in high school?It's just a memory kill.

So these playful and familiar words suddenly enlivened the classroom atmosphere.

"As I said just now, I am in charge of algebra, geometry, and calculus, that is, the three directions of mathematical analysis. Some people may think, is it okay for you to teach three courses at the same time? And these three courses Usually, we already have a teacher to give us it."

The students did have such doubts in their minds. When Qin Ke mentioned it, they became more focused.

"My answer is, yes! I don't have teaching materials for my courses. I think you have all the relevant advanced, geometry, and calculus teaching materials, and there are other teachers to teach them, so I don't need to repeat them to the books. Once again."

Students look at each other in blank dismay, don't use textbooks to teach?is it possible?How to focus on the exam?
"Are you not used to the classroom without teaching materials? Do you feel that without teaching materials, the lectures will be very scattered, disorganized, and difficult to master? Are you afraid that it will be difficult to pass the exam?" Qin Ke patted the podium lightly, and replied in a firm voice: " of course not!"

Qin Ke's eyes were calm and bright: "Some people say that mathematics is a tool, but in my opinion, mathematics is an art! Great art! Different angles and different combinations will see different mathematics. landscape!"

The slight commotion in the audience quickly quieted down, and everyone subconsciously looked at Qin Ke, moved by the momentum brought by his berating Fang Qiu.

"Before I show you the art of mathematics, let me ask you a question, algebra, geometry, counting and fractions, why do mathematics have these three different branches? Is there any relationship between the three?"

The students in the audience were stunned. The previous questions were easy to answer. Algebra is a general solution and its properties for studying numbers, quantities, relations, structures and algebraic equations.Geometry is the study of the structure and properties of space.A few points is mathematical analysis, advanced calculus, specializing in the study of real and complex numbers and their functions.

There is a big difference between the three, so it is natural to divide them into three branches. Coupled with number theory, they are the four most important branches in mathematics.

As for the relationship between them, it's really hard to describe at once.

For example, geometry studies the relationship between figures, while algebra studies the relationship between numbers...

But the students in Qiuzhen Academy are the top mathematics students selected in the country after all. After a while, some students still raised their hands and replied: "Simply speaking, with the help of the Cartesian coordinate system, the relationship between geometric figures can be described by algebra. And the quantitative relationship between algebras can also be represented by graphs.”

Qin Ke nodded with a smile and said, "What's your name?"

The boy cheered up and replied, "Professor Qin, my name is Jiang Yunxing."

"Very good, student Jiang Yunxing, add 5 points to your usual score."

Wow, the students in the audience got excited one after another, it turned out that the answer would give them the usual points!
Seeing that Qin Ke immediately aroused everyone's enthusiasm for answering questions, he smiled and said: "Student Jiang Yunxing answered the relationship between algebra and geometry just now, but didn't mention scores. Can anyone add something? Let me explain first. For a moment, if the answer is correct, the normal points will be added, but if the answer is wrong, the normal points will be deducted.”

Everyone's attitude became more cautious.

After a while, the students raised their hands: "Mathematical analysis can be cut into analytic geometry through calculus to help solve geometric problems of spherical surfaces and deformed objects."

"Correct answer, plus 5 points."

Qin Ke said with a smile: "Very good. I am very pleased by the students of Qiuzhen Academy. They are active in thinking and good at thinking. This is your advantage! But your thinking can be bolder and more open. Algebra may not be just Algebra and geometry are not necessarily just geometry. Just like Grothendieck, who is known as the "Emperor of Algebraic Geometry", summed up all algebra and geometry structures at that time, and realized the close connection between the two branches of disciplines. Professor Wiles In the process of proving Fermat's last theorem, we can also see the combination of algebra and geometry, for example, we can see modern abstract algebraic structures and elliptic curve modular structures..."

"And these are important milestones in the direction of the unification of mathematics."

"Regarding the unification of mathematics, everyone should be familiar with it. Now the ultimate goal of the international mathematics community is the unification of mathematics, explaining all mathematical problems under a framework of rules, which is like building blocks and the rules of building blocks, and then using the building blocks To build everything needed. I think this is a very good prospect, but the future will be more difficult, requiring the hard work and sweat of countless mathematical elites."

"Mathematics is like the story of the Three Kingdoms that we are very familiar with. If you are united for a long time, you will be divided, and if you are divided for a long time, you will be united."

"The branching is the inevitable result of specialization, and the great unification is the specialization is too small, which has caused the division between the branches, making it impossible for people to control the new pursuit of the overall situation of mathematics... At the beginning, the development of mathematics did not reach a high level and a wide range Gauss, who is a super mathematical genius who spans several major disciplines and is proficient in several major disciplines, will have Gauss in the field. If you change to the densely packed subdivision of the modern field, the literature calculated in TB, even if Gauss is reborn, it is impossible to be proficient. Half of them..."

Qin Ke stood on the podium and talked eloquently, from the history of mathematics to the three major branches of mathematics, and made the boring mathematics interesting.

The students also discovered that Qin Ke was not talking about any subject of algebra, geometry, and fractions, but the combination and transformation of the three. This is unique among all mathematics courses in the country.

Moreover, Qin Ke speaks in a simple way, and from time to time he will ask a question for students to come up to answer, and then continue to analyze according to the students' thinking and steps in solving the problem, and discuss with the students whether there is a more perfect and ingenious solution, whether they can pass the three The interconnection of large branches realizes the transformation of the problem. What are the benefits of such a transformation...

The more the students listened, the more exciting they felt, and the more excited they became, especially when they were learning a subject alone, many details that they could not understand were suddenly enlightened by Qin Ke's uncanny combination of explanations. Some students even thought angrily that if they had heard this class earlier, they would not have wasted so much time on those unreasonable problems and avoided many detours.

During the whole class, the students had no time to wander off, and no one dared to be distracted. While they were using their brains to think about keeping up with the class, they were taking notes quickly.

They feel as if they have come to Baoshan, where the mysteries of mathematics are everywhere. Missing and wasting is simply the most shameful behavior. How can they have the leisure to be distracted?

Even Ning Qingyun was fascinated by it. She is best at number theory, and she is also good at mathematical analysis, but she is relatively weak in geometry and algebra. After all, her two academician teachers are specialized in number theory.

Li Xiangxue was even more engrossed, and his eyes never left the pen in Qin Ke's hand.

The more serious and focused you are, the faster time passes. It seems that in the blink of an eye, the bell for the end of get out of class rang.

The students let out a collective howl.

How come get out of class is over so soon?Hearing the wonderful part!Oh no, it seems that the whole class is wonderful...

"Okay, that's the end of my class today. Don't worry, you can't become a big fat man with one bite. The road to mathematics is very long, and I will walk slowly with you. Take a break for 15 minutes, and the next class will be taught by Ning. Come give us a lesson in number theory."

The students in the audience cheered and stood up, giving the warmest applause of thanks.

The second session was Ning Qingyun's number theory class. Although the single-tailed girl did not have Qin Ke's excellent eloquence, she still explained the knowledge points of number theory very thoroughly. Listening to the girl's soft and pleasant voice was a kind of enjoyment in itself.

The students also listened very carefully, and once again gave warm applause when the class was over.

Old Mr. Qiu, who was quietly standing outside the window and had listened to two classes, and several teachers from Qiuzhen Academy looked at each other before quietly retreating.

"It's amazing. You can explain the relationship and transformation among the three branches of mathematics so brilliantly. You are indeed the mathematical genius that Dean Qiu values."

"Did you forget the several 'lime number theory processing methods' created by him and Ning Qingyun? Each of them is scientifically intertwined and blended in this way."

"Indeed, Ning Qingyun's number theory class is also very interesting. The unique knowledge structure seems to be a fusion of Academician Tian's Chen School and Academician Wang's Wang School..."

Listening to the discussions of the teachers next to him, old Mr. Qiu's eyes shone with relief and joy.

Finally, it was not in vain. I spent a lot of effort to invite these two students to give lectures. This kind of class is the most ideal class in my heart!
He looked at the distant sky, as if he saw a prosperous and prosperous future in Xia Kingdom's mathematics circle, where a hundred flowers bloomed.
