The paper is in Chinese, but fortunately, the formula is universal.

When a glass of boiled water was placed on Edward Witten, the big man just looked at the steaming glass and frowned slightly, then put it aside and ignored it.

The next moment, Qiao Ze had already written down the most important equation of the high-dimensional graviton wave function in the paper and handed it to Edward Witten.

Slightly more complicated, a completely new equation is a new challenge even for professionals.

However, Edward Witten was not in a hurry, and after reading it carefully, he waited for Qiao Ze's explanation.

Jozer didn't disappoint him either, and after he had read it once, he explained what the function was made of.

"△s is the Laplace operator in the supercoil coordinate system; v (s,t ) represents the potential energy of the graviton in the supercoil coordinate system;

"fk (Ψ, s ) is a set of nonlinear functions that describe the interaction of gravitons with supercoiled space-time, which contain the topological and geometric properties of high-dimensional spaces, as well as graviton effects derived from the second theorem of supercoil coordinate systems.

αk is the fixed curvature constant of each curve of the supercoiled coordinate system, and different curves represent different physical effects. ”

After a brief introduction, Qiao Ze was silent.

Waiting for Edward Witten to think.

As in his previous paper, understanding this function expression requires a basic understanding of the supercoil coordinate system.

Because functions involve complex geometric properties and additional physical dimensions and structures, they are even more complex if expressed in traditional equations. This is already the simplest form, and if you start with this piece, it can save a lot of time.

However, Qiao Ze soon discovered that even if Princeton started a special study, his understanding of the supercoil coordinate system was still insufficient. The frowning brow of Edward Witten on the other side said it all.

So Qiao Ze simply wrote another equation and handed it over.

This function is in a more traditional form, which can be simply understood as a direct translation of the content about the supercoil coordinate system.

"You compare the two equations first. □ denotes the Dalembert operator in D-dimensional space-time, μ is the mass parameter of the graviton, R is the D-Verridge scalar, which describes the curvature of space-time, and M is a high-energy scale that describes the physical effects of additional dimensions......"

It was clear that Edward Witten understood very quickly this time.

After a few minutes, he frowned and said, "I probably understand, but this doesn't describe the trajectory of gravitons, as you told Lott Dugan. ”

"Simple deformation is needed." Qiao Ze said succinctly.

Then he picked up the pen again, wrote down a manuscript, and handed it to Edward Witten.

Edward Witten looked up at Qiao Ze before staring intently at the formula Qiao Ze handed him.

Very confused.

"As described in the previous equation, the potential energy v ( s, t ) of the graviton is combined with the nonlinear function f k(Ψ,s) of the graviton interaction and contains a mathematical form that describes the properties of the spiral motion. Because this involves the unique topological and geometric properties of the supercoil coordinate system, I can only explain it simply.

This equation represents the spiral topological defect and the corresponding spiral energy minimization path. βk is a constant in the supercoil coordinate system, and θ(s) is the phase function related to the spiral path. ”

José watched Edward Witten's expression carefully, rather than doing anything else as usual.

Although it is a discussion, it can also be said that it is a test from Qiao Ze's point of view.

This is also the reason why he chose to give the formula directly to Edward Witten's understanding.

That's how he teaches graduate students.

It's like the last time at the report meeting, he heard Wang Yu talking below, and then came down to a theorem and asked Wang Yu to prove it as an extra homework assignment. This is not a punishment, but Joser has always believed that these formulas summarized by theorems are the best topics.

As long as you prove or fully understand the theorems summarized by your predecessors, then you will also have the corresponding knowledge.

So the materials he gave to the five graduate students also started from here.

The assignments were also given to test their understanding of supercoiled algebra and the fundamental theorems of transcendental geometry.

Now it seems that he is very efficient with this method, but it is difficult for his students.

So José was going to try it on Edward Witten first.

If even this industry boss can't adapt to his way of communicating, it probably means that the way he teaches students is indeed very problematic, and most of the responsibility for the current state of the five graduate students lies on him.

Edward Witten had closed his eyes slightly, apparently having memorized the equation in his mind, and began to think about the meaning of it in conjunction with Josser's explanation.

This made José start to look forward to, one minute, five minutes, ten minutes......

After a long silence, Qiao Ze began to become a little disappointed.

Well, the blame will fall on him after all.

This kind of highly efficient teaching innovation is something he takes for granted after all.

Although the big guy in front of him is in his seventies and his thinking is no longer agile, the precipitation of knowledge is there after all.

If even a boss of this level understands what he wants to express by relying solely on the transformation formula, it is enough to show that this teaching mode is not very universal.

Unfortunately, the three-year graduation plan was not realized. It may take two years just to lay the foundation, and then do advanced research and write a thesis, it is estimated that it will take two years, so it is good for five people to graduate in five years.

If something happens in between, it may take longer.

This made José feel extremely disappointed.

He likes to get things done ahead of schedule rather than having to put it off.

It's as if he has made a plan for himself for half a year and then finishes it in three months, which makes him feel happy from the bottom of his heart, because half of the time is saved and can be used to do other research.

The original plan had to be postponed, and the feeling it brought to Qiao Ze was probably exactly the same as the loss that ordinary people felt after learning that the first million they had saved had made a splash and that they would never come back.

Fortunately, Edward Witten's first words, which he had been silent for a long time, somewhat gave Jozer some hope.

"What about the direction? Lack of definition of direction. ”

"There is a guide axis in the supercoil coordinate system, of course you can understand that it is a special vector field, and we can use it to define the geometric composition and direction of the spiral path, and its expression is like this......"

This time José wrote fast.

For example, the guide axis a (s) not only determines the geometry of the spiral path, but also indicates the local direction of the path. For example, when a graviton moves along a spiral path, its momentum may be correlated with the direction of the guide axis. This can be described by a momentum operator associated with the guide axis a(s......"

One formula after another, Edward Witten really felt like his brain was about to explode.

He was right, Josser's theory of supercoil coordinate systems had made mathematics a quadratic abstraction.

It is probably as difficult to fully understand as it is to the remaining number theory problems.

"Tell me your conclusions first, Jozer, so that I may be able to understand them." Edward Witten said with a wry smile, then pointed to his head and said, "Don't look too highly at a seventy-year-old man, his brain cells may really not have much left. ”

Qiao Ze nodded slightly, still a little disappointed after all, but he still explained seriously: "The graviton contained in the contained quantum theory continues to interact with the Higgs particle, resulting in gravity. Its direction is determined by the Higgs particle and moves along a spiral path in the direction of the guide axis.

The spiral path is a dimension that we cannot observe, because its bending scale is smaller than the Planck scale that we can understand so far, which means that some of the energy will escape into a higher dimensional scale that we cannot observe during the motion.

But at the same time, we can find the guide axis by calculation. Theoretically, if we can interfere with the guiding axis, i.e., the a(s) vector field, it means that we have the ability to control the direction of the gravitational force.

At present, the greatest significance is probably to show that gravity has the same effect on matter as antimatter, and according to this theory, antimatter does not have the ability to resist gravity, and it is impossible to have the ability to resist gravity. At least mathematically.

Again, if my theory is correct, as long as you control the pointing axis, you can control the direction of gravity. The deeper idea is that there is no minimum resolution in the universe at present, and that there is a new physics under the Planck scale that we have not yet touched. ”

After saying that, Qiao Ze took a deep breath and said in an almost divine tone: "In other words, if I am right, then our world must be material!" God could not have created such a perfect world! ”

Edward Witten was silent, and after a long pause, he spoke, "Josser, I need to read the full paper. I can swear by my academic reputation that it will never be leaked. If you're not at ease, I can just look at it in this office, not take. I don't even need to go through the trouble of translating for me. I can ...... with the help of translation software"

Qiao Ze nodded and said, "Yes." ”

A theoretical dissertation is only mathematically almost perfect proof, and at present there is almost zero guidance for practice.

And Edward Witten flew tens of thousands of kilometers for this paper, there was no need for him to refuse.

Then Qiao Ze looked around the office that was still quite spacious, and took the initiative to speak: "I'll find someone to add a temporary table for you?" ”

"That couldn't be better." Edward Witten nodded repeatedly.

He didn't think he would be able to read the whole paper in a short time, in fact, it was impossible to think about it.

"By chance, if you're free, we'll be able to talk about the Joe's coordinate system. You know, the Joe Algebraic Geometry Research Group in Princeton is also doing this, but to be honest, progress has been slow. ”

Qiao Ze nodded, this request was not excessive.

……

"What? That Professor Witten is going to stay at the Institute of Mathematics for a while? The office is still located in Professor Qiao's office? ”

Lu Bei was shocked when he heard the news conveyed by Doudou.

Although he also specifically understood Edward Witten's status in the academic world, this professor was a professor at Princeton after all, and he settled in the secret mathematics research institute in such a grand manner?

"Uncle Lu, is this surprising to you? Isn't it very reasonable for Edward Witten to read his father's papers in his father's office? Doudou's monitor began to flicker again, indicating that after reading Lu Bei's emotion, it didn't understand this emotion.

"No, Doudou, what we do, is secret-related, and it belongs to a secret-related unit." Lu Bei couldn't help but emphasized, although the thing in front of him was not a person.

"You're stupid, Uncle Lu. Not to mention that after evaluation, Edward Witten is not a threat, and it is better if he does. If we can keep him in Huaxia, wouldn't it be more useful than keeping the Ben Ronnie last time? The value generated by that guy's screwing in Huaxia is slightly higher than his daily consumption, but Edward Witten is different.

It's a pity, if it weren't for my father's permission, I would have wanted to design a plot and keep him in Xilin all the time. The most important thing is that you seem to look down on Doudou? All the confidential content here is guarded by Doudou. ”

Doudou's words are thought-provoking, and Lu Bei only feels empowered.

And I think that the biggest problem of the Institute of Mathematics is probably the contradiction between Professor Qiao's high moral bottom line and Doudou's behavior model without a lower limit!

This artificial intelligence is really not a big deal to see the excitement, right?

Designing a little conspiracy against someone like Edward Witten? Leave people in China like Ben Ronney?

Lu Bei could only say that it was fortunate that Qiao Ze didn't agree to this matter, otherwise, his only choice was probably to resign and go home.

The follow-up series of impacts, whether it is Qiao Ze or Doudou, can probably be idle, he is the most suitable to use it to relieve everyone's anger.

The reason is that Lu Beidu helped the director above think about it.

"Professor Qiao is still young, he is understandable if he is not sensible, can you also be ignorant? What did Professor Qiao do when you let you stay in such an important position as the Xilin Institute of Mathematics, do you really have no points in your heart......

This is the world of many middle-aged people, with the embarrassment of old age and childhood.

The little ones are disobedient, and there is nothing they can do.

The old one is too lazy to listen to you, there is nothing he can do.

The old ones are unreasonable and blindly favor the small ones, and the boards will hit you, and there is no way to do it.

To argue is "He's still a kid, what does he know?" What could be wrong? Didn't you teach it well?! ”

Logically, I can't really find the slightest fault.

Thinking about it this way, Qiao Ze just wants to add a desk to the office, which is simply not a problem.

"I see, I'll arrange for someone to get the desk done in the afternoon. Do you have any other needs? ”

"I also need a coffee machine, and bored humans like to use caffeine to improve their concentration. And we can show importance by satisfying the needs of bored humans. ”

"No problem, it'll be all done this afternoon."

……

On the other side, Su Mucheng was visiting the lithography factory in the north of Xilin City today.

This was made yesterday on WeChat with Zhang and Sheng, two academicians of the Institute of Precision.

In fact, after the successful trial operation of the lithography factory, Qiao Ze was invited to take a look, but Qiao Ze was not interested.

So when Su Mucheng mentioned this matter, the two academicians were busy and accompanied Su Mucheng around the factory area on the basement floor.

It's actually a toss-up.

When entering the dust-free workshop, you have to change the ultra-clean clothes that wrap the whole person. This thing is very cumbersome to wear, and if you are not skilled enough, you basically can't complete the operation independently.

It took just a morning to walk around the entire factory, and Su Mucheng also generously accepted the banquet of the two academicians.

"Haha, Xiao Su, when you go back, you have to introduce this place to Qiao Ze."

At the dinner, Zhang Zhijian said happily.

Without waiting for Su Mucheng to answer, Sheng Xuening asked with concern on the side: "Speaking of Qiao Ze, why didn't he come with you?" ”

"Hey, don't mention it, Professor Edward Witten from Princeton is here, it was supposed to be received by Uncle Li, but Uncle Li has been very busy recently, so he can only stay in the institute to receive it." Su Mucheng said with a smile.

Although Su Mucheng is not in the Institute of Mathematics, there is a little cutie like Doudou.

At any time, he can report the dynamics of Qiao Ze's side to Su Mucheng.

"Oh? Professor Witten is coming to Xilin again? What is he doing this time? Qiao Ze hasn't heard of a presentation recently, has he? ”

Su Mucheng smiled and said, "Some of the things that Brother Qiao has studied recently may be just right for Professor Witten's appetite, right?" I don't know the specifics. ”

"That's right." The two academicians glanced at each other.

If you don't know about it, forget it, but if you do, it's still necessary to pay a visit.

"Haha, Jiangao has also been busy after becoming the director. Such a powerful scholar came, and he couldn't find time to receive it? Gone to a meeting out of town? Sheng Xuening quipped.

Hearing that the two academicians finally mentioned Uncle Li, Su Mucheng smiled even more happily: "No, Uncle Li will get married next week." I've been busy with weddings lately. Everyone knows Brother Qiao's feelings for Uncle Li, of course Uncle Li can't be kept busy with that little thing at this time. So Brother Qiao took the initiative to take care of everything. ”

"Oh? Jiangao is going to have a wedding next week? Hey, this kid, you didn't even notify us. Zhang Zhijian patted his thigh and said.

"Uncle Li said that he didn't plan to do it too grandly, so he would do it simply. Maybe I'm afraid it's too much trouble for everyone, so I haven't notified too many people, right? ”

"How can this work? I'll call Jiangao in the afternoon, marriage is such a thing, once in a lifetime, how can I do it casually? By the way, his object seems to be surnamed Mi, right? ”

"Yes, Shi Niang's surname is indeed Mi!"

"That's it, the daughter of the old Mi family, and the education system. No, this wedding is too simple, and the old Mi family still thinks that we have no confidence in building a high school. ”

"Lao Sheng is right, Jiangao is a sincere person, and it is not easy for young people nowadays, no matter what, we have to ask for a cup of wine."

Su Mucheng shrank his head and said, "Huh? Uncle Li didn't let me talk nonsense with Qiao Ze outside, I accidentally leaked my mouth just now, two grandfathers, don't tell Uncle Li that I told you. ”

"Haha, don't worry, it won't. He got married, Lao Xu must know, right? Let's just say I heard it from Xu Dajiang. Zhang Zhijian only thought it was funny, and said with a smile.

"Whew...... That's good, thank you two grandfathers. ”

"Okay, let's stop talking, come and eat, eat."

……

Xilin Digital Research Institute, Lu Bei's efficiency is very high, that is, the work of eating at noon, so he added a new position in Qiao Ze's office.

Fortunately, the previous office was spacious enough, with more than 50 square meters, and it didn't look too crowded when I added a desk to it.

In the afternoon, after learning the news that Edward Witten had arrived, Li Jiangao and Xu Dajiang also found time to visit together.

Just as Li Jiangao thought, Xu Dajiang was very excited after learning that Edward Witten had made a special trip to Xilin for Qiao Ze's thesis. By the way, a series of activities for Edward Witten have been arranged.

When a bigwig of this level comes, what does he do to keep people here, and if he doesn't hold a series of special lectures or even a series of special lectures in the academy, it is a dereliction of duty on his part.

Now the school is growing strongly.

In particular, Doudou's stroke of genius as the chief publicity officer of admissions is directly full.

Not to mention other places, the affiliated middle school next door has poached thirty-seven people from the top 100 top 100 students in the third grade of high school who were originally going to be able to pass the Qingbei high school this year, and they are all the kind that have signed a pre-recording agreement with the school.

You must know that in previous years, the number of people who could be admitted to Qingbei in the middle school affiliated to Xilin University of Technology was eighty or ninety people.

As for Qiao Ban and Ze Ban, there are many consultants, and there are more than 50 people who have pre-registered for the exam, all of whom are top competition students in China. There were even seven people who represented China in the International Mathematical Olympiad the year before and last year, and they all won gold medals.

But Xu Dajiang was not satisfied.

After all, Huaqing and Yanbei don't pay much attention to him now.

If you want to make Xilin mathematics a school of its own in the future, it is not interesting to only stare at these three melons and jujubes in China.

We still have to look further and have an international mindset.

At the very least, there must be some Harvard, Columbia, and all the momentum under their feet to create a perfect mathematics school in Xu Dajiang's mind.

Of course, this requires Xilin School of Mathematics to cultivate a number of graduates who can win world-recognized academic awards in the future in order to secure this position, but after all, that is a later matter, and before that, it seems to brush up the reputation.

One of the quickest ways to gain fame is to invite such world-class experts to give lectures.

No matter how much you can gain from a short one- or two-hour report, why do Fields Medal winners come to Huaxia instead of Huaqing and Yanbei, but come to the School of Mathematics of Xilin University of Technology to give lectures?

No way? Is it because Huaqing and Yanbei are not rare?

In short, Xu Dajiang's visit this time came with a mission.

What he didn't expect was that the layout of the office surprised him as soon as he entered the door.

Family, who knows? There's an extra desk in the office?

The Professor Witten he was thinking about was sitting at his desk and working seriously at his desk?!

Is this an edict?!
