Chapter 471 Wei Teng: How Is This Possible? !

Beijing, mid-to-late January.

As time passed, this ancient city welcomed flights from all over the world as usual.

There was a constant flow of people coming and going, but what was different from usual was that the lively atmosphere was filled with some academic atmosphere.

With five students, Xu Chuan took the high-speed rail to come here again.

He was urged by Mr. Qiu.

The old man was probably afraid that Xu Chuan would forget the "International Academic Conference on the History of Mathematics and Mathematics Education" and let the mathematics community down, so he started calling him a few days in advance to ask when he would come.

Although I understand Mr. Qiu's feelings, does he look like the kind of person who would let people down?

Obviously not.

So Xu Chuan chose to bring all five students to Beijing, in the name of an appointment, to see the world.

In fact, eat more at the banquet! Eat Shuimu University out of money!

The first time they were taken by their mentor to attend such a high-end seminar, several students were like a tail, following Xu Chuan nervously, and they were definitely students who had never seen the world.

Xu Chuan didn't care, and came to the hotel for the seminar according to the invitation letter.

It has to be said that as one of the two top universities in China, Shuimu University is really well-funded.

Perhaps in order to show the charm and history of China in front of mathematicians from all over the world, the hotel provided by the "International Academic Seminar on the History of Mathematics and Mathematics Education" for the mathematicians attending the seminar is the top-level Aman Yihe Hotel.

The most distinctive feature of this hotel is that it is not in the form of a high-rise building, but in the form of an ancient courtyard.

Entering this hotel, even Xu Chuan was a little emotional, so rich.

And the students who came with him to see the world needless to say, they were directly shocked.

Following behind his own tutor, Cai Peng couldn't help but be amazed at the luxurious courtyard, and asked curiously: "Professor, do you usually stay in this kind of place when you are on business trips?"

Beside him, the other four friends pricked up their ears and listened curiously.

Xu Chuan shrugged and said, "To be honest, this is also the first time I live in such a courtyard."

He paused, and just as he was about to add another sentence, he saw an old man in a windbreaker dragging luggage walking in from the gate of the courtyard.

He stopped talking, walked over quickly, and greeted with a smile: "Teacher, I didn't expect you to come too."

Hearing the voice, Deligne, who was dragging a suitcase, stopped, looked up, and saw the familiar person in front of him, and a rare smile appeared on his face: "Long time no see."

Xu Chuan nodded, took the luggage for Deligne, and smiled: "Yes, it's been two years."

Looking at the still young student in front of him, Deligne was a little emotional: "I heard that Qiu Chengtong brought a lot of old friends to this conference, so I came to see it."

"And being able to leave something for the mathematics community in my later years, this is my What should be done. "

Xu Chuan smiled and said: "Knowledge is never new or old. Even the methods that have been replaced have once shone in the history of civilization. It carries the dream of civilization and is a treasure worth remembering by everyone."

After a slight pause, he continued: "And the old methods sometimes have new uses. If they change to another field, perhaps they can shine again."

Hearing this, Deligne looked at him curiously: "Are you going to come up with something at this report meeting?"

He knew this student. If he hadn't found something, he probably wouldn't say that.

Perhaps, we can see something interesting at this seminar?.

Xu Chuan smiled mysteriously and said: "I will have a half-hour exchange report at this seminar. You will know then."

Hearing this, Deligne nodded and didn't ask any more questions.

It's just one day. He can wait.

January 20th.

In the auditorium of Shuimu University, the first 'International Academic Seminar on the History of Mathematics and Mathematics Education' kicked off.

It was not even nine o'clock yet, but the auditorium of Shuimu University was already crowded with people.

Arriving at the venue, Xu Chuan walked through the crowd and found his seat according to the instructions.

What surprised him was that next to him sat another old man in a woolen sweater.

"I didn't expect that you, my mentor, would come here too. Isn't CERN busy?"

Looking at the familiar old man, Xu Chuan was a little surprised.

The person sitting next to him was another professor of his at Princeton, Edward Witten.

If Professor Deligne's arrival was expected, then Witten's arrival was really unexpected.

Hearing Xu Chuan's inquiry, Edward Witten smiled and said in a teasing tone: "Although the outside world regards me as a physicist, I am an authentic Fields Medal winner, the kind with a medal."

"If even I am not qualified to attend this seminar, I can't think of who would be more qualified."

Hearing this, Xu Chuan couldn't help but cough dryly. He almost forgot that his mentor was the first to win the Fields Medal as a physicist.

I was accidentally fooled by him.

But it is true.

After all, if even the Fields Medal winner cannot attend, more than 99% of the people in this auditorium will probably leave.

After a dry cough, Xu Chuan sat down, chatting with Wei Teng while waiting for the report meeting to begin.

At 9:30, the first "International Academic Seminar on History of Mathematics and Mathematics Education" officially kicked off in the auditorium of Shuimu University.

First, the organizer of the seminar, Shuimu University, gave a brief report on the normal meeting process.

Then, the president of the International Mathematical Union IMU came to the stage to give a speech, and gave a detailed speech on research topics such as "History of Ancient and Modern Mathematics", "Mathematics Communication and Dissemination", "Mathematics Education and Mathematics Culture", and called on countries around the world and the mathematics community to protect, disseminate, develop and promote mathematical culture.

Then, the Chinese government personnel came to the stage to give a report on this seminar, saying that China will make a contribution to better promote mathematical culture research, promote mathematical development, spread mathematical culture, and lead the direction of mathematical development.

There was not much to see in the morning report.

The wonderful thing was the exchange meeting in the afternoon.

Shuimu University provided three lecture halls for scholars who came to the seminar to have different exchanges.

Xu Chuan did not wait for long. After the afternoon exchange meeting started, the second report in the No. 1 lecture hall was his time, which lasted about half an hour.

Because of the rules, around 3 pm, the No. 1 lecture hall was already full of people, and some mathematicians who came to the conference even sat directly in the aisle because they could not find a seat.

When Xu Chuan walked into the lecture hall, he saw the crowded scene and couldn't help wondering if all the scholars who came to attend the seminar this time squeezed in.

After all, the number of people was too exaggerated.

Fortunately, he was also a person who had seen big scenes. Although he was a little surprised, he still walked to the podium calmly.

After trying the microphone and confirming that there was no problem, he scanned the lecture hall and saw many familiar faces.

He smiled and slowly said, "I welcome all the scholars who have come from afar to participate in the seminar today. Today's exchange meeting is a very meaningful thing in my opinion."

"Of course, I don't need to repeat those words about protecting and developing mathematics, because I believe that everyone who can come here today loves mathematics."

"And the report I made today, to be honest, is not from the perspective of pure mathematics. The content of my report is more about the application of mathematics and its complementary physics."

"Maybe some people will not understand today's report, but I believe it will be worth it and will not waste your energy and time."

Listening to Xu Chuan's words, there was a slight commotion in the lecture hall.

Edward Witten, who was sitting in the front row, raised his eyebrows in surprise after hearing these words.

This is probably the first person in history to bring physics to a mathematics seminar.

After thinking for a while, he turned slightly to look at Deligne who was sitting next to him and asked, "Do you know what he is going to report today?"

Deligne shook his head and said, "I don't know."

After a slight pause, he remembered the unexpected encounter with this student yesterday and added, "But I am looking forward to it."

Xu Chuan didn't care about the commotion in the audience. He continued, "After thousands of years of development, the ancient discipline of mathematics has developed many branches in the past 100 years and has produced many applied disciplines."

"But looking back at history, the development of mathematics often benefits from the problems raised by physics, and every major revolution in physics is often accompanied by the introduction of new mathematics."

"The two complement each other."

"And some time ago, when I was studying some problems, I accidentally made some new discoveries. Today, I will share these results to add color to this seminar."

"Of course, it will be more inclined to the field of mathematical physics, and it may be a little difficult for scholars who are not in this field to understand, but I will try my best to report in the simplest words."

As he said, he turned on the projector behind him.

A silver-white screen slowly fell vertically.

After waiting for a few seconds, a gentle white light lit up on the screen, and a clear title appeared on the silver-white screen.

[Mathematical theory of non-equilibrium strongly correlated electron system and calculation method of a specific type of correlation! ]

A line of black regular script characters jumped into everyone's eyes.

Of course, considering that most of the scholars present are international scholars, there is also a line of English under the regular Chinese characters.

When the clear title on the silver-white screen caught the eyes of Professor Witten sitting in the front row, his brown-black pupils suddenly contracted violently, and he couldn't help but exclaimed in a low voice:

"Mathematical theory of non-equilibrium strongly correlated system, how is this possible?"

On the side, Professor Deligne, who was sitting next to him, noticed his movement, turned his head and looked over, and asked curiously: "What's wrong?"
