Zhou Hui didn't return to the hotel until almost twelve o'clock, and as soon as she walked into the room, she was startled, wondering if she had broken into something she shouldn't have entered.

Although ENS Paris is quite like Huang Shiren's, at least Wang Yinan was not badly treated in terms of living, and they generously booked a suite for Wang Yinan, which is a living room with a sofa and a large LCD TV screen. When Zhou Hui walked into the room, he saw Wang Yinan standing in front of the LCD TV, and there was a big whiteboard on the side, which should have been asked by him from the hotel.

The LCD screen is divided into four pieces, Wang Yinan's own picture is in the upper left corner, and there is a relatively young man, a very young woman and an elder of a small grade, that woman Zhou Hui knows, it is her former competitor, Li Wenjing.

It turned out that Wang Yinan put his mobile phone on the side of the LCD TV, using the hotel's network, and was conducting a video discussion across the blue star, don't you say, this discussion brought together experts from Balli in France, the imperial capital of China, Hong Kong Island in China and UCLA in the rice country, and the IQ of the participants was estimated to be eight or nine hundred.

As for the content of the discussion, of course, it was the stack of manuscript paper that Wang Yinan got in the afternoon.

Wang Yinan took a picture of each of the stacks of manuscript paper, and then sent them to the other three people, and the content on the manuscript paper seemed to have a huge magic, so that everyone put down the work at hand and participated in the discussion.

"I basically figured out the previous part, it is a combination of algebraic geometry and formal systems, this direction is very novel, and there have been few related discussions in recent times", Mr. Qiu is older and well-informed.

"From the style and details of the article, I seem to see the shadow of an old friend, but he has been out of mathematics for decades, and I don't think it should be him," said Mr. Qiu.

"The logic of the article seems to be very confusing, involving too many fields, and the author seems to hate details very much, I see that he has almost ignored all the manual work, and the proof and derivation are very unrigorous", said Professor Tao.

"But I feel that there seems to be a very consistent logic hidden in it, chaos is only the appearance, the internal logic is very rigorous, but we have to find this internal logic first," Li Wenjing added.

"I feel that the author seems to want to solve a very common problem, which should be very deeply related to our work some time ago," Wang Yinan said.

"As long as you understand what the problem is that the author wants to solve, all doubts will be solved."

The discussion was so enthusiastic, as if there was no concept of time, Wang Yinan saw Zhou Hui come in, and he just said hello casually, and continued to immerse himself in the unknown ocean.

You know, for a real scientist, the most beautiful things are those unknown things, and if these unknown things show a unique rhythm in their eyes, as if they open their mouths, when a dignitary confides something to themselves, if you let the scientist take his eyes away, to be honest, it is light to beat you.

Zhou Hui sat on the sofa and listened for a while, with her scientific literacy far higher than that of ordinary people, she felt that every word Wang Yinan said seemed to be Chinese characters, but together, how could I not understand a single word?

Being bombarded with words that she didn't understand was a terrible experience, and after a while, Zhou Hui felt a splitting headache, so she had to wash up and go to sleep.

The next morning, when Zhou Hui woke up, it was almost noon, the sun shone in through the gaps in the curtains, the dust in the room could be seen clearly, they formed a charming pillar of light, and when he walked to the living room, Zhou Hui found that Wang Yinan was lying on the sofa and fell asleep, the whiteboard was full of unintelligible words and formulas, and of course, there was a large string of question marks.

Fortunately, ENS Paris is not Huang Shiren after all, what was arranged today is for Wang Yinan to visit the scenery and museums, and he did not let a group of big cows and calves continue to ask for advice, otherwise Wang Yinan would definitely be abused to death in his current state.

Zhou Hui found a blanket to cover Wang Yinan, and when he was about to go to the museum by himself, Wang Yinan woke up, "What time is it", he asked Zhou Hui,

"It's almost eleven o'clock," Zhou Hui replied, "What time did you discuss it last night?" ”

"It's four or five o'clock, it's too brain-burning, and in the end everyone can't hold on",

"What are you discussing", Zhou Hui was a little puzzled, "This lineup is a little too exaggerated."

"Discuss a mysterious paper," Wang Yinan said.

"Or strictly speaking, it can't be counted as a thesis, after all, there are more non-rigorous conjectures and assumptions in it",

"But it's really great, it's valuable, and we all feel like it's going to be a huge discovery when we understand it thoroughly."

"What about the end, do you understand", Zhou Hui asked,

"No, some key points still haven't been figured out", Wang Yinan was a little frustrated,

"By the way, where we planned to go today",

"The Centre Pompidou", Zhou Hui said, "seems to be very close to the hotel, and it takes only ten minutes to walk there".

"Let's go", Wang Yinan said, "go out to eat by the way",

"Aren't you tired, I see you like you're about to die", Zhou Hui asked in surprise,

"As long as I don't use my brain, I'm in good shape, and I shouldn't need to think about it when I look at the art," Wang Yinan said.

"What's more, the Centre Pompidou is worth visiting, and our company's architectural style is the inheritance of the Centre Pompidou," Wang Yinan said while washing his face.

"You just talk about it, just your humble homely style, and Pompidou, leather belly", Zhou Hui casually refuted while applying lipstick.

"This decoration style of steel bars, pipelines and glass is the first application of the Centre Pompidou to modern architecture, not to mention, 90% of the IT companies in the village are very similar to this style."

The two of them staggered to this huge reinforced concrete building, in the antique Bali, such a building is really an anomaly, but this extreme incongruity has brought a different beauty to the whole neighborhood.

There are many people in front of the center, and there are various performances or exhibitions here every day, and an advertisement for a joint exhibition suddenly attracted Wang Yinan's attention, "GEB, Chaos and Order", "Look at this", Wang Yinan said to Zhou Hui,

The two of them bought tickets to the venue of the exhibition, perhaps because the content was too profound, there were few people visiting the exhibition, and a beautiful French girl stood at the door, "Do you need an explanation?" ”，

Wang Yinan was a little flustered, he glanced at the young girl, "Explanation? ”，

Then he added, "You explain to us?" ”，

"Of course, I'm a graduate student at Bali University, and I came here to work and study in the summer", the girl is very confident,

"Thank you, no need", Wang Yinan politely refused, and took Zhou Hui inside, facing the door of the exhibition hall, was a print, the painting had two hands, one left hand, picked up the pen and drew the right hand on the other side, and similarly, the right hand on the other side picked up the pen and drew the left hand.

"This is the E in GEB, that is, the painter Escher", Wang Yinan told Zhou Hui.

"Escher's paintings are full of contradictions, such as the staircase that rises infinitely in a loop, the snake that bites its own tail, or the structure that depicts three dimensions on a two-dimensional picture."

Zhou Hui was very curious and stopped in front of another painting on the side, on that painting, it happened to be the infinitely rising staircase that Wang Yinan said, staring at the stairs for a while, Zhou Hui's eyes turned around and around on the painting, and almost didn't faint himself.

Wang Yinan held her, "Do you look dizzy?" ”，

"Sort of, these paintings all feel wrong," Zhou Hui said.

"Yes, it's normal to make mistakes when using two dimensions to depict three dimensions," Wang Yinan said, "If I told you that the world around us is actually 10 dimensions, would you go crazy."

“...“

On the edge of the exhibition hall, there is a large music score, which reads "The Dedication of Music", "Bach (Boch) is the B in GEB, this should be Bach's masterpiece", Wang Yinan pointed to the score and said,

"It was Bach who arranged the music on the theme that King Friedrich gave him",

"With a lot of canon tricks, the tune feels like it's always going up, but after a few key changes, it miraculously returns to the original key."

As if hearing Wang Yinan's introduction, Bach's famous song sounded in the small exhibition hall, and this magical melody made people feel a little dizzy like looking at Escher's prints.

Wang Yinan turned his head to look, it turned out to be the music that the little girl at the door turned on just now, and she also gave Wang Yinan a thumbs up, which probably means, "You spoke very well."

Zhou Hui was a little puzzled, you are a physicist, how can you be like a god, you know both painting and music.

"Then who is the G in GEB", Zhou Hui asked,

"Also, why are the three of them put together, and why are you so familiar?"

"It's a long story", Wang Yinan said, "Have you ever read a book called "GEB An Eternal Golden Belt"",

"I haven't seen it", Zhou Hui shook his head,

"This book came out very early, at about the same time as The Third Wave, which advocated the information revolution."

"But because it's much more professional and difficult, it doesn't have much influence, and very few people know about it," Wang Yinan said.

"It seems that yes, I've heard of "The Third Wave", but I really haven't heard of any gold belts", Zhou Hui nodded.

"The author of this book is Glass. Hofstadt, a very famous expert in artificial intelligence in the seventies".

"By the way, let me ask you another question, do you know the new three theories and the old three theories", Wang Yinan asked,

"I don't know", "I don't know", this time there were two voices of answers, Wang Yinan took a closer look, it turned out that the little girl standing at the door was also standing on the side like a studious student and answered, she looked at Wang Yinan, and said embarrassedly, "I recognize you, you are Professor Wang who gave a lecture at ENS Paris yesterday, and I also went yesterday, but there were too many people to squeeze in."

There seems to be no harm in having multiple students, not to mention that this student is not too ugly, Wang Yinan continued,

"The old three theories are cybernetics, systems theory and information theory, which are traditional macroscopic theories, and the main source of ideas can be considered to be Mao Xiong, and of course the cybernetic master who is worth five divisions",

"The new three theories are dissipative structure theory, synergy theory and mutation theory, of course, this statement is not rigorous, but from the evolution of the new three theories and the old three theories, we can see a lot of interesting things",

"In this, I think the book "GEB An Eternal Golden Belt" is indispensable",

"Don't sell it, the more you talk about it, the more confused you become", Zhou Hui was ready to do it.

"Don't, don't, I said", Wang Yinan hurriedly raised his hand to surrender.
