The Science Fiction World of Xueba

Pang Xuelin narrated this period of history, and the classroom was quietly heard. Everyone was attracted by the story of Abel and Galois, and also became very interested in group theory.

"I thought Pang Shen's lecture would be boring, but I didn't expect it to be so interesting."

"Shen Pang is really good at fooling around. After hearing about the achievements of Galois and Abel, it aroused my desire to learn mathematics in an instant. It's really scary... Fortunately, reason helped me curb this evil thoughts."

"Galois and Abel are awesome, you said I'm starting to study hard now, is it possible to be like them?"

"Hmph, it's just you, think too much, the one on the podium is about the same!"

...

From time to time, there were slight discussions from the audience, and unconsciously, more than an hour passed.

Pang Xuelin looked at the time and said: "Okay, today I will talk about the history of algebra, the origin of group theory, and the stories of two great mathematicians, Abel and Galois, about how Galois and Abel passed group theory. Thoughts prove that there is no root solution for the quintic equation in one variable. We will formally explain it in the next class. The reason why I have talked so much with you is that I hope that you can always keep your heart on the road of learning mathematics. In the near future, Among all of you here, there can also be mathematicians like Galois and Abel who can fundamentally promote the progress of human civilization! There are still 20 minutes left, and if you have any questions, you can ask them at any time."

There was a buzzing sound in the classroom, and soon, each arm was raised high like a forest.

"This classmate, yes, is the one wearing glasses and a plaid shirt!"

Pang Xuelin pointed to a boy sitting in the back row.

Soon, a dull-looking boy wearing thick glasses got up and said, "Professor Pang, I have previewed the concepts related to abstract algebra before class, but it was very difficult to understand. I would like to ask if it is suitable for me. Do you recommend any reference books?"

Pang Xuelin laughed and said: "Well, let me recommend a few books to you. The first one is "The Basics of Abstract Algebra" by Mr. Qiu Weisheng. The second book is "Field and Galois theory". This book is characterized by step-by-step, and each theorem is clearly proved. In addition, I especially recommend Lederman's "Introduction to Group Theory". The treasure for beginners should be available in our school library. You can compare this book with Mr. Qiu Weisheng's "Abstract Algebra Basics". The content of the two books is the same, and the proof methods are almost the same, but different people Using different narrative methods will give you completely different feelings, and it will also give you a deeper understanding of some basic concepts of abstract algebra."

"Thank you, Teacher Pang! I will collect the books you recommended as soon as possible."

The boy with glasses sat down, and Pang Xuelin pointed to a tall and thin boy and said, "Student, do you have any questions?"

The tall and thin boy said: "Professor Pang, I would like to ask. Recently, it has been rumored on the Internet that you have proved the BSD conjecture. Is this news true?"

As soon as the voice fell, the classroom was silently heard, and all the students focused their attention on Pang Xuelin.

Although the proof of the BSD conjecture has not been officially made public, there have been many rumors on the Internet and in the school. Most of the people here understand the importance of the BSD conjecture, so they all want to hear what Pang Xuelin himself has to say.

Pang Xuelin smiled slightly and said: "I did write a proof paper on the BSD conjecture, but this paper is still in the peer-review stage, so I can't tell you whether I have proved the BSD conjecture, which requires colleagues in the mathematics community We will give you an answer, but I think this day should not be too long!"

The boy said again: "Teacher Pang, how sure do you think your proof is correct?"

Pang Xuelin said: "As far as I am concerned,

Since I have submitted that paper, I am 100% sure, but we still need to wait and see whether it will be recognized by my peers in the mathematics field! "

"Thank you, Teacher Pang!"

The tall, thin man sat down.

At this time, a female voice suddenly came out of the classroom: "Mr. Pang, you just named the boys to ask questions. Now it's our girl's turn, right?"

Pang Xuelin followed the prestige and found that it was the beautiful mixed-race girl he had seen in the morning who made the noise.

Pang Xuelin smiled and said, "Okay, student, do you have any questions?"

The mixed-race girl stood up with a sly smile on her face and said, "Mr. Pang, I want to ask if you have a girlfriend?"

With a buzz, the originally serious class instantly became lively.

Ha ha ha ha--

The students roared with laughter, and many boys even whistled.

The mixed-race girl pursed her lips tightly and looked at Pang Xuelin with big eyes without blinking. Pang Xuelin said helplessly: "Not yet!"

"Then have you ever been in love before?"

Pang Xuelin said: "This is a personal question, can I refuse to answer it?"

The girl smiled and said: "Okay, then I will change the question, Teacher Pang, do you have a girl you like now?"

Pang Xuelin patted his head. Are the post-95s and post-00s all so fierce?

After a while, he replied: "No!"

The mixed-race girl nodded in satisfaction and said with a smile: "Mr. Pang, thank you, I have no other questions!"

Fortunately, after the girl asked the question, the get out of class bell rang on time.

Pang Xuelin couldn't help but heaved a sigh of relief, and quickly said: "Okay, today's class will end here first, and get out of class is over now!"

"well……"

Many people in the classroom immediately let out a sigh, as if they were a little disappointed that they could no longer see the scene where the mathematician molested the student god.

Pang Xuelin put his laptop into his computer bag, packed his things, and followed the flow of people out of the classroom with his computer bag.

Before taking two steps, there was a call from behind.

"Teacher Pang, Teacher Pang!"

Pang Xuelin stopped in his tracks, and saw the tall mixed-race girl running up to him in small steps. When she got closer, the girl was no longer as generous as before, and her delicate pretty face was slightly flushed. , sweetly smiled and said: "Mr. Pang, I was sorry just now. I was a little too excited to see my idol, so the question I asked was more sensitive. By the way, if I apply for your graduate school in the future, you will not brush me off." Bar?"

Pang Xuelin had a headache and said: "Then you have to work hard, I have very high requirements for students!"

The mixed-race girl clenched her fists and said, "Teacher Pang, don't worry about this, I will definitely meet your requirements. By the way, my name is Ai Ai, you must remember it!"

Pang Xuelin was slightly taken aback: "Ai Ai?"

Ai Ai smiled and said: "My father is Chinese, his surname is Ai, Ai from Ai Cao, and my mother is British, her name is Alice, so they named me Ai Ai."

"Okay, I remember!"

"Teacher Pang, then I won't bother you, goodbye!"

"goodbye!"

Pang Xuelin looked at Ai Ai's bouncing back, couldn't help but shook his head with a smile.

Just then, his cell phone rang suddenly.

Pang Xuelin was slightly taken aback, picked up the phone and pressed the answer button, and Liu Tingbo's hearty laughter came from the other end of the phone: "Xiao Pang, Tao Zhexuan just published a blog, officially acknowledging your proof of the BSD conjecture, which is The first heavyweight mathematician in the world to publicly acknowledge your achievements may cause a storm of public opinion, so you have to be mentally prepared!"

Pang Xuelin smiled and said: "Dean Liu, don't worry, I know it well!"

Soon, Pang Xuelin returned to the apartment, turned on the computer and posted Tao Zhexuan's blog.

In the blog, Tao Terence comprehensively analyzed Pang Xuelin's proof paper on the BSD conjecture, and made such an evaluation: "The correctness of a mathematical proposition depends on whether the conclusion is concise and powerful. Pang has done a great job. He On the issue of the BSD conjecture, he has blazed a new path, starting with the problem of congruent numbers, and finally completing the proof process of the entire conjecture. This is another masterpiece after Perelman completed the proof of the Poincaré conjecture in 2002."

Pang Xuelin couldn't help being a little moved. He is just a little-known mathematician in the world. The BSD conjecture uploaded to arXiv before only caused a certain reaction in the mathematics community. All major media are still in the wait-and-see stage.

Tao Zhexuan made such a statement now, while pushing himself to the forefront, he also built up his academic reputation.

However, to some extent, it also shows Tao Terence's confidence in this paper.

Terence Tao's influence is extraordinary. Half an hour after his blog was posted, CNN first reported the relevant news: "Not long ago, the Chinese mathematician Pang Xuelin published a paper on the proof of the BSD conjecture on arXiv, which recently won the Fields Medal. The winner, Professor Terence Tao from the University of California, Los Angeles, publicly admitted that a reporter from our station interviewed Raymond, a researcher at the Cray Mathematics Institute in the United States. Raymond said that the Cray Institute has organized relevant experts to verify the results!"

As soon as CNN finished reporting, major media outlets around the world followed up.

Associated Press: "Chinese mathematicians overcome the seven millennium problems and are expected to win a million-dollar prize!"

BBC: "The seven major math problems of the millennium have made another breakthrough, and the 23-year-old math prodigy in China has shown extraordinary talent."

Reuters: "Chinese mathematician Pang Xuelin claims to have completed the proof of the BSD conjecture, and won the support of Fields Medal winner Terence Tao!"

Xinhua News Agency: "Professor Pang Xuelin, a Chinese mathematician, recently published a 63-page BSD conjecture proof paper on the internationally renowned paper preprint platform arXiv, which has attracted widespread attention in the mathematics community. According to the introduction of Professor Qiu Chengtong, an internationally renowned mathematician and the first Chinese Fields Medal winner, Pang Xuelin The establishment of the proof scheme has been widely favored by the academic community, and the results are currently being further verified."

...

Major media around the world reported the news that the BSD conjecture was proven, and Pang Xuelin was caught in a storm of public opinion.

In less than half a day, Pang Xuelin received more than one hundred calls from major media around the world.

God knows how these reporters got their own private cell phone numbers.

Except for a few words at the beginning, Pang Xuelin simply set the phone to silent, and refused to answer all the calls except for a few.

On the Internet, discussions about Pang Xuelin and the BSD conjecture quickly spread from niche forums to the entire network.

On the hot search list on Sina Weibo, the hot search with Pang Xuelin as the keyword ranked first, the second place was BSD conjecture, and the third place was actually the million dollar prize...

At the same time, Pang Xuelin's photos and related resumes from childhood to adulthood were also picked up and put on the Internet.
