There were two major events at Xilin Mathematics College in mid-June.

One is Edward Witten's special lecture on Friday, and the other is the wedding of Li Jiangao, a well-known professor at the school, on Sunday.

The former is the college took the initiative to advertise it on the official website, and I can't wait to announce it to the whole country.

Xu Dajiang almost asked Doudou to help him publicize it.

As for the latter, Li Jiangao still didn't want too many people to know, and even many colleagues didn't inform him.

Helplessly, when the outside world found out, it naturally spread to the unit.

Originally, Li Jiangao didn't even notify his friends Jiang Da, Zhang Chunlei, Liu Jian, Chen Xujiang, and Wang Ming, after all, everyone is usually in different cities, and it is inconvenient to come here on weekends.

But in just a few days, not only a few old friends knew, but all the professors who had a relationship with him called one after another. In a word, invitations are a must, and weddings are a must.

In the end, it became a well-known secret, and everything was useless.

And Li Jiangao also came back to his senses.

Everybody's planning is good.

It just so happened that Edward Witten was coming to Xilin, and there was a briefing. I happened to come to listen to the report on Friday, stay in Xilin for a day on Saturday, attend the wedding at noon on Sunday, and go back to their respective homes by high-speed train in the afternoon, which is just perfect.

Come on, let's come, but what made Li Jiangao worried was that he only wanted to do it simply, so he only booked three tables in total and prepared another table. Then I called the hotel and wanted to add a table, but there was no place for them.

But with so many people coming, four tables were clearly not enough.

Fortunately, Xu Dajiang still listened to some of Xu Dajiang's words.

His face may not be big enough, but José deserves it. Just gave José a call.

Of course, Qiao Ze didn't pay attention to these things, and directly said to Su Mucheng.

Xiao Su may not be so powerful, but Xiao Su's father is stained with Qiao Ze's light, and now he is a celebrity in Xilin.

After a few phone calls, I simply changed to a more upscale hotel and took down the entire restaurant.

Su Lixing didn't talk to Li Jiangao about money, just said: "You are Qiao Ze's mentor, I am Qiao Ze's future father-in-law, speaking of which, we are all a family with the same spirit, and we will take care of each other in the future, so it's not interesting to talk about money!" ”

What's more, I have to thank you for bringing Qiao Ze to Xilin, otherwise it would not have been possible to achieve this marriage! In this way, there will not be many red envelopes, and it will be interesting when the time comes. You don't have to worry about the cost of the hotel, don't talk about it, it would be really hypocritical to talk about it again. ”

Facts have proved that an academic professor like Li Jiangao can't argue with a businessman like Su Lixing.

In the final analysis, he is actually too thin-skinned, and he is not at all an opponent like Su Lixing, who started his own business after graduation and then crawled in society for decades. In a few words, he was defeated.

In this way, Li Jiangao waited until Friday in the daily phone and WeChat bombardment.

Edward Witten's day of giving a presentation in a large conference hall.

……

Friday morning, Institute of Mathematics, Qiao Ze's office.

After reading the paper and writing and drawing for more than two hours, Edward Witten leaned back, looked at Qiao Ze, who had been quiet next to him, and asked, "Will you be attending my report this afternoon?" ”

"What are you going to say at the presentation that is deeper than what we usually talk about?" Qiao Ze looked up and asked.

"Obviously unlikely. In fact, a report of this nature would not be able to say those things. You know, there's not that much time, just a few superficial things. Edward Witten replied.

"So what's the point of me going? Squandering time? Qiao Ze asked rhetorically, then turned his gaze back to the computer screen in front of him.

Edward Witten was a little bored.

Qiao Ze is good at everything, but he doesn't care about human feelings at all, which makes people angry.

Isn't it a crime to squander two hours?

He came to Huaxia to participate in Qiao Ze's two report meetings, and now he is making a report at the door of Qiao Ze's house, but this guy is too lazy to go.

"What I'm trying to say is actually ...... Well, in the words of the Chinese people, it is a courtesy exchange? ”

Qiao Ze raised his head and looked at Edward Witten with a thought-provoking expression.

After a moment, Qiao Ze's words were so sincere that he was ashamed.

"You are too active in academia, and you often attend various conferences and presentations, which seriously affects the efficiency of your research. For me, it's a negative textbook. ”

Forget it, he suddenly didn't want to invite Qiao Ze very much.

This young man is not interesting.

In comparison, it is still the dean Xu Dajiang who is cute.

"Joze, do you have any friends?" Edward Witten couldn't help but ask.

Qiao Ze thought for a moment and replied uncertainly: "It depends on how to give a friend an accurate mathematical definition." ”

Edward Witten was stunned for a moment before he spoke: "Qiao Ze, friends can't be defined by mathematics!" ”

Qiao Ze thought for a while and said, "Not necessarily, it can be explained by graph theory. Set an undirected graph, e.g. g=(v,e), so that v is the set of nodes in the graph g, each representing a person. e is a collection of edges, and each edge { u,v }∈ e represents a friend between nodes u and v. ”

After saying that, Qiao Ze thought carefully for a moment and added: "Well, if you understand it this way, I can be regarded as having 1.5 friends and a girlfriend." ”

Edward Witten's brows furrowed and he asked, "1.5 friends?" ”

"Well, the three roommates are half friends, and they add up to 1.5 friends." Qiao Ze nodded, affirming this conclusion.

Edward Witten was at a loss, and then suddenly felt that he should carefully comb through the contents of the afternoon's briefing. It's okay to make friends, he doesn't want to be an incomplete person himself.

I don't know how the 1.5 friends in Qiao Ze's mouth will feel when they hear Qiao Ze's words today, but he really thinks that if someone says that he is only half a friend, he will feel offended.

Qiao Ze glanced at Edward Witten and saw that the big guy had nothing to say, so he nodded at the other party and continued to get busy with his own business.

Unlike these idlers, he has too much to do.

Edward Witten opened the school's official website and looked at the introduction again.

Presentation: "New Physics After the Discovery of the Graviton"

Speaker: Edward Witten

Place:......

Introduction:......

Looking at the introduction of his life on the official website, Edward Witten's tangled mood at this time calmed down a little.

Fortunately, there is only one freak like Qiao Ze, and if there are more, it will be very uncomfortable.

When did it become derogatory to appear more active in the academic world?

……

At noon, Xu Dajiang and the school leaders came to invite Edward Witten to the luncheon.

Edward Witten was keenly aware that everyone just said hello to Qiao Ze, but no one opened their mouths to invite.

Although he was not very interested in Qiao Ze's communication method, it still made him very confused.

So sitting in the box, I couldn't help but ask: "I noticed just now, you don't seem to have invited Qiao Ze to dinner?" ”

Hearing this question, Xu Dajiang was the first to laugh: "Haha, Professor Witten, you don't know anything." Qiao Ze used to be willing to eat with us old men, but then he didn't bother to pay attention to us. He didn't think we talked too much during the meal, and he didn't want to talk to us much. ”

"Yes, there are a lot of people who want to invite Professor Qiao to dinner. But there are too few people who can be invited. If he spoke, he must have refused, and he was still annoyed. So now there is a tacit understanding. I simply don't mention it. Principal Chen also sighed on the side, and then glanced at Li Jiangao, who was sitting there silently.

He didn't want to invite Qiao Ze to some banquets, but unfortunately his face was obviously not enough in Qiao Ze's area, and Qiao Ze didn't want to ask him for invalid socializing.

Now that Li Jiangao's wedding can be so popular, Chen Yuanzhi suspects that it is because he is probably the only person who can invite Qiao Ze to participate in this so-called ineffective social network.

According to Qiao Ze's theory, Chen Yuanzhi suspected that all social interaction in this world was probably ineffective.

However, the words of the two made Edward Witten feel more comfortable.

It's good, it seems that Qiao Ze is not only impatient with him, but also with everyone else.

Of course, for a person with only 1.5 friends, this is probably normal.

……

At two o'clock in the afternoon, the lecture hall that can accommodate more than 300 people was full.

There were not many students who came, only about 30 people, and most of the places were occupied by professors who came to visit.

This once again made Edward Witten, who was sitting on the podium, feel a sense of relief.

Although, as Qiao Ze said, he is very active in the academic world, often attending various conferences and giving presentations at conferences, the feeling of coming to China this time is still different after all.

Especially when I think that even the taxi driver he met by chance at the airport had read his book and even waived his fare......

Well, Edward Witten didn't care about that fare.

After driving such a long way, it was less than fifty dollars, which was even quite cheap for Edward Witten, who had never taken a taxi in Huaxia. When he took a taxi in the United States, although there were slight differences in each city, the distance was about the same, and the tip basically fluctuated around $80.

So to this day he still believes that the taxi driver read his writings.

Of course, it may also be because he has written a lot of books.

"I'm glad to be invited here today to give this lecture, but in fact, I have always felt that the topic of this seminar is actually more appropriate for Professor Qiao Ze from the Xilin Institute of Mathematics, as we all know, the graviton is derived by Professor Qiao Ze with a very mysterious mathematical method, and in this way revolutionizes the whole theory of quantum gravity, and I have only done some trivial verification work.

In the same way, I came to Xilin this time and stayed in Xilin for so long precisely because Professor Qiao Ze solved a key problem related to the world of microscopic particles, that is, the wave function equation containing gravitonns. It's a very curiously structured equation, and it may not be as beautiful as the mass-energy equation, but if you dig into it from a microscopic perspective, you can see how perfect it is. ”

As the words fell, the screen behind Edward Witten showed the equation that José had explained to him on his first day.

This is an opening magnification move.

The audience was in an uproar.

What's the situation?

Graviton wave function equation?

How long has it been?

It's hard to push?!

Is there really no limit to a professor's inspiration?

The most crucial thing is that Qiao Ze completed the work without publicizing it.

They even had to learn about it from a report from another foreign scholar?

Is José busy?

With such a significant achievement, he was not even willing to hold a report meeting?

As for Gao Lengcheng's appearance.

……

Edward Witten stood on the podium, smiling, not in any way annoyed by the sudden commotion from the audience.

That's exactly what he was hoping for.

Qiao Ze's idea was too extreme.

How can there be a student who does not press his paper to publish it in order not to be stimulated?

He didn't mind helping Qiao Ze become famous at all, because this guy was already famous enough, and there was no shortage of him to put the icing on the cake for this one.

But if everyone advises José to publish his paper quickly, he will benefit the entire physics community.

Now it seems that it really worked well.

From his point of view, he could even see Xu Dajiang and Li Jiangao, who were sitting in the front row, being frequently questioned. That's a good sign.

Most of the people who can sit in the front row of the report meeting are the most prestigious and respected seniors in the academic world.

These people are all interested in the paper, and Qiao Ze has no reason to hide it, right?

As for Qiao Ze's students......

Truth be told, Edward Witten felt that Qiao Ze's academic career was going too well, and it was necessary to recruit a few more stupid students to make him understand the rules of the world, and it was time for him to suffer some setbacks, and there was nothing wrong with giving him a perfect academic career a little color.

As for Li Jiangao, who was sitting in the audience, he and Xu Dajiang faced various problems and chose a modest smile.

This is also what Xu Dajiang explained earlier.

They had seen the PPT prepared by Edward Witten in advance, and they also expected the reaction on the spot.

A humble smile means that although we already know this, we don't want to make a big deal about it.

Look, the School of Mathematics of Xilin University of Technology is moving forward in a low-key, simple, and calm manner, which is different from the glamorous goods outside that are eager to be publicized with great fanfare if they have some achievements. There are a lot of good things, but we just don't advertise them......

Fortunately, there are many bigwigs who participated in this report meeting today, and there are academic bigwigs of Edward Witten's level on the stage, and it only looks like it will be two or three minutes, and the audience will gradually fall silent.

"So today I'm going to start today's report with the discovery of gravitons and their implications. The content of the report will include the following four aspects: understanding the fundamental interactions, the verification and challenge of theories, the impact on cosmology, and new research directions in physics.

In fact, the discussions with Qiao Ze these days have made me deeply aware of some serious shortcomings or inherent flaws in the theory of quantum gravity. Before I get into that, I'd like to quote a quote from José as an opening.

In the future, he said, we will reveal the deepest secrets of the universe in the slight flutter of gravitons, and finally prove that even the smallest of points hide infinite power and connection. ”

……

A Fields Medal bigwig, when giving his own report, used the words of a young theoretical scientist in his twenties to make an opening statement, and replaced any young scientist, which is a kind of honor.

But if it was Joze, it seemed to be a normal thing.

However, those in the audience who knew José were suspicious that Edward Witten had done some processing, and they could hardly imagine that such a beautiful description could come out of Josser's shriveled words to the point of outrageous mouth.

And that's just the beginning, because the next report will be a surprise to see if there is something wrong with Edward Witten.

Because it's hard to imagine that one bigwig's report could be filled with another person's point of view.

José said......"

"José suspects ......"

"José thinks ......"

"Josser's explanation/understanding/opinion on this is ......"

Really, for a while, Xu Dajiang felt wrong.

Big man, I invited you to do your own report meeting, not for you to be a substitute for Qiao Ze. Change Qiao Ze's name to me, are you Qiao Ze holding a report meeting?

No, José's report never says anything so shallow.

The guy will probably assume that these are things that everyone understands and understands, and will only analyze and interpret those complicated formulas, and dryly demonstrate the proof process, and try to simplify the otherwise tedious proof process as much as possible to fit the time of the presentation.

If you have to describe it, Qiao Ze's report will probably be the kind that doesn't contain a little moisture, it is all dry goods, and it is so dry that you can't find any moisture.

Edward Witten did a good job of not being too obsessed with the formulas and the proof process, but focusing on the implications of the study and deriving some results. When it comes to the theoretical part, only some mathematical ideas that focus on the proof process will be discussed.

Although it will be another hour or two, there is no doubt that Edward Witten's report will sound more relaxed. For those who can immerse themselves in it, it can even be described as funny, and of course, there are many thought-provoking places.

This is probably the same reason that rice that is too dry is difficult to swallow.

This also proves once again that water is the real source of all things, and human beings cannot do without water at any time, after all, there are too many times and places that need to be lubricated.

All in all, Edward Witten's presentation was a great success.

The report meeting was successfully concluded.

Edward Witten chatted with some acquaintances at the scene, and after leaving the venue, Li Jiangao became the focus of the stars.

"Jiangao, congratulations! You're not kind, I still know the news that you're getting married from Da Zhang, what's the matter? This is to be motivated, and I plan to dissociate myself from us. ”

"Hi, Professor Liu, you know I'm not that person. It's not that it's not easy for you to come from Anseong. The journey is tiring, and I have to go back to work after a meal, for fear of delaying things. ”

"You can't come to me if you ask for anything else. But what trouble are you afraid of when you get married? ”

"That's it, Jiangao, you're going to be criticized this time. Is it appropriate to engage in such a raw point? It seems that I will have to toast you a few glasses of wine the day after tomorrow. ”

"Hey...... Spare me. ”

"Haha, let me be fair, Brother Jian Gao is indeed a good intention, let's not embarrass him. Just one request, at the wedding the day after tomorrow, arrange your most proud students with a few of us at the same table, isn't that too much? ”

"Brother Zhang, you may have misunderstood my relationship with Qiao Ze. I usually listen to him now......"

"If you're going to say that's the case at work, I believe it. But at your wedding, I don't believe he can arrange it for you. ”

"Hehe......"

Li Jiangao wanted to say that even the hotel where he had dinner the day after tomorrow was arranged by Qiao Ze's father-in-law.

But after thinking about it, I held back.

After all, there are not only a few old friends today, but some of them are so deep that people think he is showing off.

Honest people are like this, they will always subconsciously consider the perception of others, and they are not free and easy.

At least it can't be done as Xu Dajiang said, go directly sideways.

"Hey, okay, okay, let's have a meal together tonight, and tomorrow you're sure to be busy with a bunch of things, so we won't bother you."

"Okay! Today I invite everyone, but first of all, I will pick up people tomorrow, and we can't drink. ”

"Okay, let's go, no one is drinking!"

……

The video of Edward Witten's presentation was previously signed and can be used for live streaming and replay.

The live broadcast and playback are fully operated by the Zhijie live broadcast academic platform of the Chinese Academy of Sciences. This platform itself is a public welfare academic video platform produced by the Academy of Engineering, and most of the content collected is also a variety of academic reports by top experts in various fields.

It has nothing to do with money.

Edward Witten's report is attractive enough, the scene will certainly not fit so many people, not everyone has the time to listen to this kind of report live, to maximize the effect, do live video and playback is naturally the most convenient, these will be the future of valuable academic audio-visual materials.

And for a dean who is obsessed with the influence of the Internet and is unwilling to give up any promotion of his own family, it is natural that he will not mind opening the door in this regard.

The two sides can be said to hit it off.

However, probably no one expected that this purely academic report would become popular on the Internet.

There is no other reason, there are also too many idlers in the academic world.

Probably someone who watched the report meeting and found it interesting, and directly began to edit how many times Edward Witten mentioned José in the two-hour report meeting, and then edited out all the sentences that mentioned Joze.

In just 90 minutes of the report meeting, after editing all the sentences mentioning Qiao Ze, it was as long as seven minutes and thirty-two seconds.

It was very interesting, so I simply posted it in the group.

"Come, let's count how many times Professor Witten mentioned Joser after a presentation."

This immediately aroused the interest of countless entire groups.

You may not think about it when you watch it, but when you edit it all together, it's really interesting......

"Is it mentioned so many times? I also watched the live video, but I really didn't find it. ”

"This is to help Qiao Ze hold a report meeting, right?"

"In this way, I am more interested in Professor Qiao's latest paper. It is said that Edward Witten came to China this time to discuss gravitons with Qiao Ze, but unfortunately he only saw a formula? ”

"By the way, what about Professor Joe's paper?!"
