From Almighty Scholar to Chief Scientist

Chapter 389 Witten Arrives
"Professor Lin, I have read your paper, first of all, please let me express my admiration for your mathematical skills."

When the physics world was once again in shock, Lin Xiao received a call from the United States.

The caller was Edward Witten, the founder of M theory.

Lin Xiao was a little surprised by Witten's call. Of course, he also knew that it must be because of the paper that he called to communicate with him.
After hearing Witten's first words, Lin Xiao couldn't help laughing and said, "Haha, Professor Witten is being modest. You are also a winner of the Fields Medal."

"I don't need to talk too much about these problems. Anyway, after studying Ni's multidimensional field theory many times, I haven't found out that such delicate deformation can be performed at all. The only one who can find this kind of connection is Professor Lin. .”

Witten said.

Indeed, as Witten said, Lin Xiao's thesis is based on past theories, and to do this, one needs to have a keen sense of knowledge and a sufficient amount of knowledge.

Without these two, it is obviously impossible to do this, so this is why Witten admires Lin Xiao.

Otherwise, if it was easy to do, Lin Xiao's achievement would probably have been discovered by other physicists a long time ago.

This is like Maxwell's equations. The first version of the equations produced by Maxwell was composed of [-] equations, including [-] variables, so even if the things in it already existed in the academic world, But it takes a genius mind to do it.

"Hehe, it's a great honor for me to receive such praise from Professor Witten."

Regarding Witten's praise, Lin Xiao smiled, and then said: "Of course, after talking so much, let's talk about why Professor Witten came to me."

"Well, it's actually like this, Professor Lin, I deduced some of the content in your paper, and then came up with some surprising results."

"Oh? What is it that even Professor Witten attaches so much importance to?"

Lin Xiao couldn't help being interested.

Witten said it was amazing, so it must be very heavy, right?

Witten said: "As you said in your paper, the graviton in the standard model of our three-dimensional world is extended to a four-dimensional form by means of integration, then if we do not integrate, but differentiate How about going down?"

"Is it differentiating?"

Lin Xiao thought about it, and was taken aback for a while: "Can it be differentiated exactly four times?"

"Yes, it is quadratic. After all, this function is not smooth. Therefore, if we follow the realistic intuition, after differentiation to the cubic, it is equivalent to changing from three-dimensional to zero-dimensional, regardless of the graviton in the zero-dimensional space. What will it look like, but why can we still differentiate next? It can't be negative one dimension, right?"

Witten joked again: "Or from zero to eleven suddenly?"

After all, the upper limit of the dimensional space of M theory is eleven dimensions.

However, Lin Xiao didn't understand his joke, but thought about other things.

After hearing Witten's idea, he related this method to the problem he was actually working on, that is, the Yang-Mills gauge field existence and mass gap problem.

The paper he produced was originally intended to serve this problem.

At this time, Witten's question gave him an idea.

That is, what if he also uses the form of continuous differentiation to analyze the gluons and quarks in the strong force?

His distraction caused Witten to call out in doubt: "Lin?"

"Oh!" Lin Xiao came back to his senses, and then smiled: "Witten, I know what you mean, what you want to say is that the result of continuing to differentiate is the string you dream of, right?"

Witten said: "Yes, it's strings... To be honest, this differentiation process is really difficult. If I didn't refer to your integration method, I don't know how long it would take-of course, it is precisely because So, I think that's the string, because the end result, it's so simple and beautiful, it's like I'm seeing the string in digital form."

Lin Xiao pondered for a moment, Witten's idea also made him very interested, and he also supported Witten's idea, after all, for this person, discovering strings is of great significance.

Although in this regard, he has to say sorry to Witten, because he had already found the decisive evidence to prove the existence of strings in the demonstration of wave coherent superposition equations.

Of course, Witten's idea also gave him the idea of ​​having more exchanges with Witten.

Thinking of this, he said: "Witten, I can't agree more with your idea. In addition, I also have some other ideas, and I want to discuss more with you, so... Do you want to come to China for a while? ?Now I invite you to be a visiting researcher at my institute so we can have more discussions."

Hearing Lin Xiao's proposal, Witten was taken aback for a moment, and then after a short thought, he readily agreed: "I think, I have no reason to refuse, and it just so happens that I can come to Huaguo for fun."

Lin Xiao suddenly smiled and said, "Then I welcome you."

……

In this way, it was decided that Edward Witten came to Dingguang Research Institute and became a visiting researcher at Dingguang Research Institute at the invitation of Lin Xiao, and it was also spread.

It seems quite normal, after all, academic exchanges, coupled with Witten's reputation, it is not a big deal to be invited to be a guest researcher, but the academic circles know that Lin Xiao's paper has just been published not long ago At this time, it turned out that Witten was going to discuss with him at this time. Could it be that they were going to do something big?

Of course, no one knows what sparks of wisdom will arise between a leader in string theory and a leader in multidimensional field theory, so we can only guess.

For the domestic physics community, Edward Witten's visit is also a matter of concern, and he will even conduct research at the Dingguang Institute for at least one month, which can't help but attract more attention. Dingguang Research Institute.

Some are envious, some are jealous. Of course, the Dingguang Research Institute has always been a big attraction, and there are too many lice and it is not ticklish.

In this way, in mid-April, Witten set off from the United States and came to Lin Xiao's Dingguang Research Institute.

"Witten, we meet again."

Seeing Edward Witten getting off the car, Lin Xiao greeted him with a smile.

"Forest."

Witten also smiled and nodded towards Lin Xiao, looking at Lin Xiao's still young face, his heart once again gave birth to those emotions, probably when he is all gray-haired, Lin Xiao will still be like this Are you young?
Afterwards, Lin Xiao didn't keep chatting with Witten. He didn't have too much formalism here. At least he wouldn't let people go through the process after sitting on a plane for more than ten hours, so he took Witten nearby first. Let him have a good rest for a day, and then go through some procedures, such as the ceremony of hiring Witten as a visiting researcher at the Dingguang Research Institute.

After that, Witten officially became a member of the Dingguang Research Institute, and he was the only foreign scientist.

At this time, the two finally had the opportunity to conduct academic exchanges directly.

……

"What? Lin, what you want to study is actually the problem of mass gap?"

When Lin Xiao said the problem he wanted to solve, Witten said in astonishment.

"Yes."

Lin Xiao nodded, "I think, current physicists want to really understand the strong interaction force, right? And this is exactly what I want to solve."

"And if we can unify quantum mechanics and relativity, then this problem, I think, will be easily solved."

"I buy it." Witten couldn't help but exclaimed, "If I hadn't come, I probably would never have thought that your purpose would be this."

Lin Xiao smiled and said, "No matter what, at least I have taken the first step."

"Yes." Witten nodded slightly.

In that paper, Lin Xiao has taken the first step. The theory of relativity has been involved with quantum mechanics, and the bridge in the middle is the graviton under the multidimensional field theory.

"So, Witten, what do you think about this?"

Hearing Lin Xiao's question, Witten began to think quietly, and after a while, he suddenly said: "It is still difficult to achieve the unification of the two and a perfect fit, but you You should know about progressive freedom, right?"

"Of course I know... Wait, what do you mean?"

Lin Xiao nodded slightly, and suddenly, he understood Witten's meaning.

Witten smiled and nodded at him, "Yes."

He knew that Lin Xiao had already understood what he meant.
