I really just want to be a scholar

Chapter 376

Unsolvable groups are another difficult point in group theory, and after nearly 40 minutes of intensive knowledge bombardment, most people's brains are still buzzing. When they hear this question, they all look confused and dare not raise their hands to answer.

Fortunately, everyone soon noticed that Professor Xu was not looking at him, and they were relieved. Many people also followed the professor's gaze curiously.

Oh, it's that top-notch beauty with a strong literary atmosphere and the physics department boy next to her.

Qin Ke also noticed Professor Xu's gaze, but he didn't intend to stand up and answer.He just came to accompany his girlfriend to attend lectures, and he didn't want to make publicity, let alone hit the Yanda students in the classroom.

Seeing that Qin Ke "dare not" or "can't" answer, the students in Yandali began to gloat.

It's nothing more than a student from the Department of Physics who came to sit in on a professional class in our School of Mathematics. He dared to bring such a beautiful girlfriend to "show off". This time, he was targeted by the professor, right?
The most "happy" thing is that this arrogant guy can't answer!
"Professor Xu, can I go directly to the stage and write the answer?" Suddenly a boy stood up.

"can."

The boy gave Qin Ke a provocative look, then strode up to the blackboard, and wrote out the proof process: "S2 is an exchange group, so it can be solved; [S3, S3]=A3, [A3, A3]= {(1)}……"

After writing, he threw down the chalk smartly, grinned at Ning Qingyun again, and gave Qin Ke a demonstrative look before walking back to his seat.

There are still a lot of good people in Yanda. This student just went down, and then two students went up one after another. They used two different proof methods to prove Professor Xu's question, and without exception, they walked back to their seats after writing the answer. , all cast provocative and mocking glances at Qin Ke.

The way schoolmasters attract girls' attention is often this way, showing off what subjects they are best at, especially in front of her boyfriend, and stomping them into the dust to prove that they are far better than her boyfriend.

Professor Xu nodded slightly: "That's right. These three proofs are all good, but they are not innovative enough. Has anyone else thought of a new proof? Especially the proof of the insolubility of S5."

None of these three proof methods satisfied Professor Xu?
The Yan University students who were present were collectively silent, and even the three academic masters who were somewhat proud of themselves frowned and thought hard.

"Let me try to prove the incomprehensibility of S5." A melodious girl's voice sounded in the silence, and then the students of Yanda University were surprised to see that wearing black-rimmed glasses and a pure white beret, The cute literary girl with twin ponytails stood up, walked briskly onto the podium, and picked up the chalk.

A question arose in everyone's mind in surprise.

She wants to prove this difficult problem that only three top scholars in the whole classroom can prove?

But I saw the girl standing in front of the blackboard, holding the chalk in her slender white and jade-like hands. After a moment of contemplation, she saw the nib of the pen flying, and the dust fell, and then the beautiful handwriting outlined a line in the light projected from the window. Proof of the line:

"Proof 4: If S5 is solvable, then there is a normal subgroup N that makes S5/N interchangeable. Let f be the natural homomorphism from S5 to S5/N, and examine the three-term cycle (a, b, c) ∈S5, take another two elements d, e. Let x=(d, b, a), y=(a, e, c)..."

"That is, x-1y-1xy=(a, b, c) ∈ N. Therefore, N contains all three rotations. Similarly, its normal group sequence contains three rotations, so it is impossible to end at 1."

The air in the classroom was almost still at this moment, only the thin sound of breathing and astonished and unbelievable gazes were left, all focused on the pretty girl on the podium.

Professor Xu was stunned for a while, with a look of admiration in his eyes, nodded and said: "That's right, this proof method is quite new..." Before he finished speaking, he stopped suddenly, and then talked with the boys from Yanda University in his class. Together, stare wide-eyed at the girl with twin ponytails, and continue to write "Proof 5: Suppose N is a non-trivial normal subgroup of An..."

The elegant and dignified handwriting took about 3 minutes to complete "Proving the Fa 5". Then the girl bowed slightly to Professor Xu, put down the chalk lightly, and returned to her seat with a scent of lime-like fragrance. superior.

Quiet, the audience was silent, as if the air had been pulled out, the boys opened their mouths in disbelief, looked at the "Proof 4" and "Proof 5" on the blackboard, and then turned to look at the man wearing a The girl with double ponytails who wore black-rimmed glasses but still couldn't hide her exquisite beauty looked like a dog at this moment.

She originally thought she was a liberal arts girl who came to accompany her boyfriend to attend classes, but she turned out to be a peerless expert who could shatter the void in mathematics!
Compared with her, the sophomore in the School of Mathematics of Yanda University, Xueba was completely crushed into scum!
I don't know who applauded first, and soon thunderous applause resounded throughout the classroom. The boys looked at the girl with twin ponytails with a kind of sacred and pious gaze, as if looking at the most perfect girl in their hearts. goddess.

Yes, she is so good-looking, has such a high IQ, and studies so well, what is it if she is not a goddess?
When the applause subsided, many boys were asking each other, which college did this vaguely familiar beautiful girl belong to? Why have I never heard of such an outstanding female student in science before?

In the midst of these whispers, the girl only heard: "Is there any problem with my proof?"

To everyone's surprise, what she said was not to the professor on the podium, but to the boyfriend next to her.

Everyone was stunned again, and all their eyes were on the boy from the physics department.

The boy who also wore black-rimmed glasses, a blue baseball cap, and the brim of the hat was pressed a little low gave a thumbs up with a smile: "No problem, it's amazing to be able to come up with these two proofs in such a short period of time, I Proud of you!"

The girl with two ponytails showed a shy and charming smile, and said again: "I believe you must have other proofs, you can go up and write about it."

The boy with glasses smiled: "Forget it, it's enough to have these two proofs, don't affect the professor's class."

"But..." The girl looked at the boys around with a little displeasure, as if she was not happy with the provocative gazes of the boys on her boyfriend just now, she just went up and wrote two innovative proofs, just to fight back against those provocative The eyes of my boyfriend.But in the bottom of her heart, she is still the same as other girls, and she hopes to see her boyfriend go up and easily crush all dissatisfied domineering appearances.

The boy with glasses smiled and shook his head: "I'm here to accompany you in class, so why bother with others?"

Hearing what the boy with glasses said, the high-achieving students of Yanda University felt uncomfortable.

Damn it, you admit that it's okay to come to accompany your girlfriend to class, but what's the matter with your attitude of disdain and mediocrity?

A tall and thin school bully who had gone to the podium and wrote the proof 2 snorted coldly, and said to himself: "It's so funny, some people can only brag and talk in front of girls, but they talk like they are so good."

He didn't even turn his head, and kept staring at the blackboard, and his voice was very low, but because the classroom was very quiet, most of the people still heard it, and laughter immediately rang out.

"squeak--!"

The sound of seats moving interrupted the harsh laughter.

It was the boy with glasses who suddenly stood up, gently took off his glasses and hat, put them on the table, and walked to the podium with his head held high.

Everyone only saw his back, and found that this boy was quite tall, in his early 1.8 meters, and he was quite strong.

Professor Xu next to the podium saw his face clearly, and suddenly froze.

The boy smiled at Professor Xu: "I'm sorry, Professor Xu, is it okay to waste a little time in your class?"

"You...you can do whatever you want." Professor Xu didn't seem to expect this boy to appear in his class, and he didn't recover for a while.

The boy picked up the chalk, dragged his hands in the mud for half a second, and wrote three words in correct handwriting-"Proof 6", followed by lines of mathematical formulas.

His writing speed is very fast, his movements are smooth and fluid, and he finishes it in one go, which makes people dazzled. In less than 1 minutes, "Proving the Fa 6" has been written.

Then, the boy who was ridiculed by the students of Yanda just now for only bragging in front of his girlfriend, didn't give everyone any time to digest, and continued to release the second round of shock.

"Proof 7: Let φ∈S5 be 3-rotation...".

The whole classroom was stunned, watching him write from "Proof 7" to "Proof 9", writing densely in the remaining space on the blackboard, and the mathematical symbols became more difficult to understand as he went to the back , even the three most powerful mathematicians in Yandali were stupefied, their mouths gaping open.

Only Ning Qingyun's eyes were shining, she pursed her lips and smiled, and looked at her boyfriend on the stage proudly.

At the end of the writing, the boy finally stopped the chalk and said to Professor Xu, "I'm sorry, Professor Xu, there is no space on the blackboard, so I won't write Proof 10 and Proof 11, is that okay?"

At this moment, under the podium, the YSU students felt that his back was unusually tall, as if it was like an unattainable mountain, which made everyone breathless.

The three academic masters who were provocative before only felt their faces were hot, as if they were slapped several times in the face, and they felt like they were beaten to pieces.

Professor Xu stared at the blackboard for a long time, especially Proof 9. He looked at it for almost 2 minutes before showing a smile of admiration and admiration: "Amazing!" He looked at the boy and the girl with two ponytails in the distance, He smiled and said: "So it's you, no wonder you don't even need to take notes. Why did you two come to my class?"

"Professor Tian Jianlan recommended that your 'Abstract Algebra' course is the best in China, let us sit in and learn a thing or two."

Professor Xu shook his head and said with a smile: "With your current level, isn't it a waste of your time to attend my class?"

The boy hurriedly said: "Where is there, I listened to your class with great interest, especially your alternative interpretation of symmetry groups and conjugate classes in class, which benefited me a lot."

"Okay, okay, don't flatter me, I can't give you credits anyway. If you two really like it, come and listen to it, and I can print two more copies of the exam papers for you to do. But it's okay Don't hit my students like today again, I'm afraid they will be autistic collectively." Professor Xu said at the end, and let out a hearty laugh.

The boy smiled shyly: "Isn't this forced? You can't be bullied in front of your girlfriend and keep silent, right?"

"You... that's fine, go back and sit down, I'm going to continue my lecture." Professor Xu smiled and motioned the boy to go back.

Seeing the conversation between the boy and Professor Xu who seemed to be very familiar, the students of Yanda University were even more puzzled.

Until then, the boy finally turned his head and walked off the podium with his head held high. Everyone saw his face clearly for the first time.

I don't know who took a deep breath first, and said in a voiceless voice: "Qin...Qin Ke?"

The whole classroom suddenly exploded.

"Damn it, I still said which guy is so terrifying, it turns out to be the famous God of Qin!"

"Hey, could it be that the girl just now is... classmate Ning?"

"It must be classmate Ning, no wonder I always feel a little familiar! I think so, so good at science and such a good-looking female student god, who else in the world besides classmate Ning?"

"Qin Shen, student Ning, why did you come to our Yanda University to attend lectures? Do you think our Yanda University is better? Welcome to our Yanda University!"

"When it comes to mathematics, we are Yan Daniu, Qin Shen, why don't you just transfer to another school and become our alumni? By the way, give me an autograph after class is over!"

Qin Ke smiled slightly: "Hello everyone, Ning and I are just ordinary students who are observing. Professor Xu's class time is precious, and I hope everyone will cherish it."

Although Qin Ke and Ning Qingyun did not show any outstanding performance while sitting in their seats, the sensation caused by the exposure of their identities did not subside until Professor Xu coughed heavily.

Professor Xu pointed at the blackboard, and said simply: "You can at most read Proof of Fa 6, and the rest is the knowledge of graduate students. You can't understand it for the time being. Alright, let's continue the class..."

One sentence caused countless sighs of shock and shock.

On the same day, the news of Qin Ke and Ning Qingjun's appearance at Yanda University was uploaded on Yanda's BBS. Many students in the classroom began to pay attention to the strange students who were unfamiliar, and many of them wanted to make friends with each other. These two famous academic gods...

Qin Ke and Ning Qingyun actually only attended two classes at Yanda University, and then returned to Qingmu University by bicycle to continue their courses.

It was different in Qingmu University. Although the freshman compulsory courses were taken by more than a hundred people from the Department of Physics, many of them were unfamiliar with Qin Kening and Qingyun, so they would cast their eyes curiously, but they were all from the same department after all. , the dormitory is also close, and it is not difficult for a thick-skinned person to visit and get to know each other, so the attention it has attracted is not outrageous.

Qin Ke and Ning Qingyun's first week of college courses was busy and relaxed.

Speaking of being busy, it was naturally because both of their schedules were full.I said it was easy because the two of them came to each class with the mentality of swimming in the ocean of knowledge, and did not force themselves to learn a certain level, so their mentality was very peaceful and their spirits were in a relaxed state.

After half a month of relaxation, Qin Ke's brain, which had been fully loaded for a long time, finally recovered. The faint feeling of soreness in his temples has disappeared, his thinking is clearer, and his learning efficiency is higher.

Only then did he resume his studies and scientific research.

In terms of study, he mainly uses his free time to continue to absorb the remaining basic knowledge of chips and study the physics textbooks specified by Academician Jiang, about two hours a day.

In terms of scientific research topics, the first thing to start is the Polignac conjecture.

It’s just that this conjecture is very difficult. Qin Ke tried it for a while and found that the construction method should be applicable, but the “finite number system” cannot prove Polignac’s conjecture, and a new system must be constructed. It takes a lot of time to ponder, and it is certainly not something that can be overcome in a few months, so he is not in a hurry, and only spends about an hour a day studying Polignac's conjecture.

The compilation of high school supplementary materials, the arrangement of knowledge points in charge of Qin Ke, and the supporting exercise booklets have all been completed. At present, they are mainly writing the storyline with Ning Qingyun. This project is estimated to be completed in mid-October.

As for the subject of plant cross-breeding, Qin Ke has taken the time to complete all the cross-breeding of rice, corn, wheat, rape, and tomatoes in the virtual world, and has accumulated detailed experimental records. Wei Xueming, a researcher in the Plant Cultivation Laboratory, and several farmers were responsible for the implementation, and the artificial intelligence "Shimmer" also took over the temperature and humidity control work in the greenhouse through the remote control function, and accurately controlled the temperature and humidity in the greenhouse according to the temperature and humidity curve entered by Qin Ke. Implement and record relevant video data.

—— Ning Qingjun is responsible for regular contact with the plant cultivation laboratory, collecting and sorting out real experimental data, and improving the theoretical part.

What Qin Ke really spends the most time and thought on is his "Cabbage Cultivation Program".
