From Almighty Scholar to Chief Scientist

Chapter 399 Erased blackboard, write again
The familiar Beijing auditorium, as well as some familiar faces, of course, there are also some unfamiliar faces.

However, these unfamiliar faces are only unfamiliar to the auditorium of the Beijing University, but to the physics community, these people are all familiar faces.

Among them are Juan Maldacina, who also came from the Institute for Advanced Study in Princeton, as well as Nobel Prize winners in physics Penrose, Jim Peebles, Gross and so on.

All in all, if these physicists disappear, human physics may have to stagnate for at least 20 years, or even longer.

Of course, if everyone else except these physicists disappears, then let alone physics, mathematics will probably stagnate for decades.

Because many familiar faces present are the world's top mathematicians who have come here several times to listen to Lin Xiao's report.

For these mathematicians, they have been here too many times recently, and they are all familiar with the way when they come in.

"Hey, Deligne, was the bun just delicious?"

"Oh, it's Roujiamo, Roujiamo, Pompieri, not Mojiarou, please correct me."

"Oh! Look at my memory, I almost forgot again, it's Roujiamo."

Deligne and Pompieri continued to chat about the original Rougamo issue, while Maldacina next to him heard the conversation of these two colleagues and couldn't help asking curiously: "What are you talking about? Steamed buns, steamed buns with meat?"

"Oh, it's the breakfast we ate today. It's a unique snack in Huaguo and Qin Province. You can try it more." Deligne said with a smile, "It's called Roujiamo, it's...well, it's like a hamburger, It's just that instead of sandwiching meat with bread, they sandwich meat with pizza-like dough."

"Oh, so it's this one. I remembered it. I saw it today." Maldassina nodded, and then said: "But speaking of this, I recommend you to try the snack called tofu nao, especially It’s salty tofu nao, that’s a must.”

At this time, a voice came from the side: "Salty tofu nao? No, no, you have to eat sweet tofu nao, it's delicious."

Maldassina turned his head and said, "Witten, Witten, you have completely forgotten us old fellows, and you are reluctant to go back after staying in Huaguo?"

"Of course not." Witten said with a smile, "It's probably the sweet tofu that makes me want to stay."

"Hehe, then you still have to try salted tofu nao." Maldacina said, "You will find another world."

"No no, you probably haven't tried sweet ones, you..."

The two foreigners just started arguing over sweet and salty tofu, which confused Deligne and Pompieri next to them. Is there any difference between sweet and salty?

So they discussed whether they should try separately next time.

Of course, as time passed, it was almost ten o'clock, and everyone present became quiet, and did not talk about other things. After all, they all knew that the really important thing was Lin Xiao's few days of lectures.

Everyone present was a little impatient.

Especially physicists like Maldacena.

Compared with those Nobel Prize winners who came here just to witness the history of the physics world, they have already achieved their fame, but for a young physicist like Maldassina, he still needs a Nobel Prize winner. Bell Prize in Physics to thoroughly prove himself.

Even in the current physics world, the main force of research is young physicists like them.

"Witten, you have been with Lin for a long time, do you know how to report to Lin?"

Just before the start, Maldacena asked Witten in a low voice.

The people around also looked at Witten, showing curiosity.

Witten shook his head and said, "I don't know the details."

"However, all I can say is that there will be surprises in this report, and it will probably be a big one."

"big surprise?"

Everyone else became curious.

And at this moment, the host stepped onto the stage.

The host is the dean of the School of Physics. Facing those faces who are extremely well-known in the academic world, Dean Wang said with a smile: "Hello everyone, welcome to all respected professors and doctors who have come here from a long distance. After today, the monument of physics will once again be added with a rich and colorful touch. At the same time, our physics will also open a new page. From then on, we will study the theory of everything without worrying about It's relativity and quantum mechanics after all."

"Then, don't say anything else, let's invite our protagonist now, welcome Professor Lin Xiao!"

Applause rang out, and everyone present saw that very familiar figure walk onto the stage.

No matter for mathematicians or physicists, Lin Xiao's figure is very familiar to them. For mathematicians, Lin Xiao's figure has been engraved in their hearts. For physicists, Lin Xiao The report that proposed the multidimensional field theory, this young figure, has made them unable to forget.

"Hello everyone."

At this moment, Lin Xiao, who came to the acting stage, faced every scholar off the stage, with a faint smile on his face, and then bowed slightly.

"Then, most of the friends here should know me, and I basically know every friend here, so let's start directly."

Lin Xiao opened a PPT, the PPT is very simple, basically there is no bells and whistles.

On the first page of PPT, there are only a few words
[Gravity, graviton, relativity, quantum mechanics]

"The reason why everyone came here is very clear to me, and it is probably because of my original paper."

"Especially the derivation process from the NP problem to the P problem."

"Yes, from the NP problem to the P problem, I have also read the article written by Professor Faltings. The description in it is very correct. I did use the ideas in the P=NP problem."

"Here I also want to thank Professor Witten. If he hadn't accidentally mentioned a P=NP problem, I probably wouldn't have changed my thinking to this direction."

Speaking of this, Lin Xiao also smiled and glanced at Professor Witten, and everyone present looked at Witten in surprise. He never thought that Lin Xiao would think of using this problem in computing technology and mathematics to solve their physical problem. , actually because of the inspiration provided by Witten.

At this time, Lin Xiao also smiled and said, "Then, in this report, I will focus on how I use the P=NP idea to solve my problem."

Turn the page of the PPT, and then an explanation of the P=NP problem appears above.

For the scientists present, it was not difficult to understand the meaning of this question, but there were also some school students sitting in the back row, especially those from the School of Physics, who participated in this report.

It's just that when these students saw the question given by Lin Xiao, they immediately showed a confused expression.

What does this question mean?
Now they can't even understand the meaning of the question.

Of course, Lin Xiao obviously wouldn't take care of these students, and didn't waste time on it.

Soon, after telling these things, he moved into the explanation of his steps and ideas, which is the most important thing for the physicists and mathematicians present.

Because of this idea, it is very likely that it will help them in their subsequent research.

And then, under Lin Xiao's detailed explanation, the steps that they were still at a loss when they read the thesis, they suddenly understood at this moment.

In the seat below, Maldassina said in amazement: "Oh my God, it turns out that it is like this, is it possible to reconcile and transform Einstein's field equations? Such mathematical ability... This is really enviable. ability."

"Yes, that's true." Witten nodded and said, "I thought I had understood his steps, but I didn't expect there to be such a deep meaning!"

"Professor Lin, what else does he know?" On the other side, in the professor's seat of Shangjing University, Dean Zhao Qi was also amazed.

Next to him, Xu Ji shook his head and said: "Probably not, number theory, algebraic geometry, differential geometry, cohomology, harmonic analysis... I really can't find it, and now he has shown this in computer mathematics. Tell me he can prove that P=NP, and I'm probably willing to believe it."

"Fortunately, he is a member of our school." Zhao Qi said with a smile, but at this moment, he caught sight of Wang Changsheng, the dean of the school, who was sitting in another row of seats, and his smile froze immediately. Then silently covered his heart.

It hurts, it hurts too much.

……

In this way, Lin Xiaowei perfectly explained the most incomprehensible part of his paper to everyone present.

At this point, everyone present also understood, but at this time they also understood one thing, that is, Lin Xiao's method, only Lin Xiao can use it, and it is very difficult for them to use it.

Because this is a kind of virtuosity that Lin Xiao performs in mathematics, just like a pianist named Liszt, who created the piano virtuoso school because his piano skills are too good, so that only he can play some songs Come on, the method Lin Xiao gave at this time is exactly the same.

This is Lin Xiao's unique skill, which requires inspiration and technology to complement each other. It is very difficult for others to use it. At least the time it takes needs to be multiplied.

Thinking of this, besides being helpless, the people present were also shocked.

It is unbelievable that only one person can use a mathematical method.

And then, this report became simpler. The next steps, those present basically read Lin Xiao's paper and understood the latter part, can also deduce it.

So, Lin Xia quickly finished the last part of this paper.

However, just when the people present thought that today's report was over, Lin Xiao suddenly erased the words on the blackboard and started to write again.

[U(a,L)A(x)U(a,L)...]

Seeing Lin Xiao's steps, the people present were puzzled for a while, but soon, someone exclaimed: "This is... the existence of the Yang-Mills gauge field?!"
