From Almighty Scholar to Chief Scientist

However, under the reminder of Witten at this moment, it brought another inspiration to Lin Xiao.

Because, at this moment, the direction he wants to study has become the unified theory of relativity and quantum mechanics.

"So, as you said, it is difficult to truly achieve the unification of the two, but this does not prevent us from starting in the direction of progressive freedom."

"Well." Witten nodded, and said: "Quantum mechanics and relativity are not contradictory in many respects, but this does not mean that they can tolerate each other. The key to unifying them lies in gravity."

"And since we want to unify the four fundamental forces as stated in our goal, we might as well assume that the four fundamental forces are unified. Although we don't know the form, we can still base on this To extend the framework, to explore the mysteries of each other, perhaps, you can find some clues."

"Yes."

Lin Xiao nodded in agreement, and he was sure of the next research direction in his heart, and then he couldn't help laughing: "It seems that inviting you over is a very correct decision. With full confidence."

"Haha." Witten smiled, and then said: "Of course, your question is yours, and mine is mine. Do you have any other ideas about strings?"

"of course."

Lin Xiao nodded.

Back and forth, since Witten has brought him help, he naturally needs to bring some help to Witten's problems.

Of course, regarding Witten's question, he has actually thought about it these days.

In the process of studying diffraction, he had proved the existence of strings in an indirect way through mathematical demonstrations and proofs from subsequent experimental phenomena.

For Witten, the existence of strings is the one thing he hopes to see most.

After all, M theory, or the entire string theory, is developed based on the existence of strings, but so far, no experiment can directly or indirectly prove the existence of strings, and in the future, there is no known experiment able to clarify this.

Because it requires a collider with a very large collision energy to complete this feat, which is larger than an earth, which is obviously unrealistic.

For Lin Xiao, being able to find traces of strings in diffraction is mainly based on the properties of light, or electromagnetic waves.

But it’s still the same, how he found the string method at the beginning, obviously he couldn’t tell Witten, the role of wave coherent superposition equations in national defense has become more and more important, and it has become a state secret theory, so anything that may lead to Its disclosure or things that are also deduced by others are not allowed.

Of course, how to avoid the confidential content here, and find another way to prove the existence of strings, Lin Xiao has roughly some ideas.

So then he told Witten this method.

"Starting from the photons in the process of electromagnetic interaction force interaction?"

Hearing Lin Xiao's suggestion, Witten couldn't help being stunned.

"Yes." Lin Xiao nodded and said, "Since it is impossible for us to start from the actual experiment, we should start from these basic particles composed of strings. I always believe that many phenomena in the microscopic world should have strings. The role of the string is involved, and as long as we eliminate these things and find things that may have the characteristics of strings, perhaps, we can find the existence of strings."

Just like the process when he discovered the existence of strings, it was realized based on this method. Some clues about strings were found in the diffraction of waves, and then the existence of strings was confirmed.

"Get rid of those things?" Witten thought about it, and said after a while, "Is it like your 'mathematical vaccine'?"

Lin Xiao was taken aback for a moment, then nodded with a smile, and said, "Yes, at least in terms of form, the relationship between the two is very similar."

The mathematical vaccine is the mathematical method he created in CERN to eliminate the errors caused by noise in the experimental data, which is quite similar to the method he said.

Witten nodded. He was at CERN with Lin Xiao at the beginning, and he also witnessed how Lin Xiao used this mathematical vaccine to find the proof of the existence of artificial black holes in those data.

Then he laughed and said, "Speaking of which, I didn't think of your mathematical vaccine at the time. Looking at it now, it feels like a P=NP problem."

"P=NP?"

Lin Xiao was taken aback for a moment, then nodded, it was true.

How to understand what the P=NP question is about is like understanding a tongue twister, but to put it simply, you only need to know that the entire cryptography is based on the assumption that P is not equal to NP, and once it is proved If P=NP, cryptography will collapse, because through P=NP, all passwords can be easily cracked within a certain period of time.

And Lin Xiao's mathematical vaccine is very similar to this.

However, Witten's seemingly off-topic ridicule gave Lin Xiao some extra thoughts.

P=NP problem?

Seeing Lin Xiao suddenly thinking again, Witten smiled slightly. This is the case for a genius. A casual word from others may bring a seemingly unintentional reminder to the genius.

He used to be such a genius, but now, Lin Xiao also showed this enviable talent in front of him.

So then, he waved his hand and said, "Okay, it seems that Professor Lin has gained some additional gains, and of course, I have also gained some gains, so let's do this first, I have to go back and start my research .”

Lin Xiao came back to his senses, then smiled and said, "Okay, then I wish you a pleasant time here."

"Of course, thank you. Let's talk about it later when I have an idea." Witten nodded and said, "Of course, if you have something you want to discuss, you can also come to me."

"Okay." Lin Xiao nodded, and then the two bid farewell to each other, leaving Lin Xiao standing alone thinking.

The inspiration given to him by Witten before and the current P=NP problem actually have certain similarities, but the latter is closer to the essence.

so…….

"Maybe they can actually be combined and think together?"

"Hmm..." Lin Xiao lowered his head and pondered for a moment, then his eyes lit up slightly.

He knew what he had to do.

"P=NP, what a good question."

Shaking his head slightly, he left here.

Although the P=NP problem is mentioned, it does not mean that he is going to solve this problem again.

If the P=NP problem is really proved, he doesn’t have to think about solving the so-called Yang-Mills gauge field’s existence and mass gap problems, he just designs the program and finds a powerful supercomputer , Maybe after a while, this problem will be solved directly, and there is no need for him to waste time here.

Let alone this problem, even the Riemann conjecture and the BSD conjecture can all be solved directly, making the so-called Millennium Prize problem a history.

Of course, although this cannot be done, he can develop a method similar to the form of P=NP for his problem with common sense, just like his "mathematical vaccine" root check method, just like This special version of the P=NP form for particle collider data.

Then, he can easily find the answer that perfectly fits quantum mechanics and relativity.

As for how to develop this special edition P=NP form...

In Lin Xiao's mind, a storm of thinking began to set off.

And maybe it was the experience brought by the original study of Root Cha method that gave him an idea soon.

"Right, that is it."

When he raised his head, his eyes lit up.

Then, he quickly ran back to his office and started to follow his thoughts.

……

Time flies, and four weeks pass quickly.

"Phew~ It's finally done. From the looks of it, it's basically right, this is it."

When Lin Xiao raised his head and stopped the pen in his hand, a piece of straw paper filled with various symbols appeared on his desk.

If you show it to someone who doesn't understand mathematics, you will definitely think this thing is a ghost.

But Lin Xiao's heart was full of joy at this moment.

This thing is his special version of P=NP, which is specially designed to solve the unification problem of quantum mechanics and relativity.

Including this last page, he worked on a full fifty pages before completing this method.

Of course, the next important step is to input these contents into the computer and turn them into programs to run.

After all, since P=NP, of course a computer is needed to verify it, and without the help of a computer, it is obviously impossible to rely solely on personal calculations.

As for how to convert these mathematical formulas to the computer...

"Uh... let's find someone."

A full fifty pages, if it is written as a program, God knows how many lines of code it will take to run, so he chose to find labor.

Fortunately, there is still such a labor force in their research institute.

So he found four intern researchers in the institute who were very good at writing programs, and then handed over this task to them.

The four intern researchers were very excited about the task that Lin Xiao gave them, and they had no dissatisfaction, so they agreed directly.

Then it took them three days to convert all the mathematical processes of this fifty-page paper into a computer program.

Next, Lin Xiao can start running these programs, and then verify, under what conditions can quantum mechanics and relativity be unified, or in other words, they cannot be unified at all.

3Chapter [-] Did running the program cause problems with Shenwei?

"Thank you."

After taking over the USB flash drive from the four intern researchers, Lin Xiao naturally wanted to thank them well. It took three days to get it done. It is conceivable that they must have spent a lot of time. After staying up all night, after all, Lin Xiao gave them a week at the beginning.

"It's nothing, Lin Shen, please be polite."

"That's right, Lin Shen, you are my idol, so I'm sure it's fine to do things for you."

"It's all small things. After all, Lin Shen deserves to be you. No matter how I look at your formulas, I can't understand what you are talking about, so I can only write out the program according to those formulas."

Naturally, these intern researchers are also young people, and they are not so reserved when talking to Lin Xiao.

Lin Xiao laughed, and then said: "No matter what, thank you very much."

No matter what, if you let people do things, you have to give them a little help. It is obviously not good to ask people to help you and not give them any benefits.

So Lin Xiao thought for a while, and said, "Well, since you are all researching computing materials, I will give you a special grant of 40 yuan, and the four of you can work together on a project."

Hearing Lin Xiao's words, the four of them were immediately overwhelmed with excitement.

Lin Xiao's words are tantamount to supporting the four intern researchers to work on their own projects, and this is obviously a great reward for the intern researchers.

Generally speaking, intern researchers can basically only follow the big cows or young cows in the research institute to do research projects. If you want to set up a research group and conduct research alone, you must either have the money to rent a laboratory to do research, or it is impossible. .

After all, intern researchers do not have the experience of doing projects alone. Before they grow into full-fledged researchers who can handle their own work, they all need to follow those seniors to do projects, get familiar with the project process, and then wait until they have the opportunity to lead projects alone. On the road of becoming a Maverick-Daniu, of course, there may be no news halfway.

But now, several of their intern researchers have the opportunity to apply for funding and set up a project independently, which is undoubtedly an opportunity for them.

"Of course, you can each share the 40 yuan research funding and study your own research. I don't hinder that. However, I think that for your research materials, although it is calculation materials, I think [-] yuan should be spent. It's a little more than enough."

"So you need to think about it. After making a decision, print out a project application form and just come to me."

"Okay, that's it, I should go too."

With that said, Lin Xiao was about to leave, and he still had to verify the program in his hand.

The excited four people came back to their senses and shouted, "Thank you Lin Shen! Goodbye Lin Shen!"

Someone even shouted in a funny way: "Congratulations to God Lin!"

Hearing this "respectful farewell", Lin Xiao shook his head with a smile, and then left here.

Giving these people 40 yuan, Lin Xiao is not worried that the money will be wasted indiscriminately. He still has confidence in the people in his research institute.

And now giving them 40 yuan is not only to thank them, but also to cultivate them, to see if they can use the 40 yuan to cultivate talents. Even if one of the four people shows enough talent, it is good matter.

As for those minutiae, it is not something that Lin Xiao needs to think about. Even if it is 40, it is nothing to him now.

No longer winning the championship, he returned to the office with the USB flash drive, and then directly entered the Sunway TaihuLight system.

Since he has an internal account, he doesn't need to queue or anything. He directly connects to the supercomputing node, and he copies the program in the U disk into it. Next, he will hand it over to the supercomputing node for calculation.

P=NP focuses on a process of solving problems in polynomial time. As for what polynomial time is, in a word, it refers to problems that can be solved in a deterministic time, that is, to verify the problem by continuously giving answers. , can be regarded as a method similar to brute force.

Through exhaustion, all problems can be solved like a monkey typewriter, it is only a matter of time.

For simple problems, it takes a relatively short time to solve this similar exhaustive method, and when this simple problem is complicated, that is, after the scale of exhaustive enumeration becomes larger, the time required The timing problem will obviously become bigger, or even impossible.

But P=NP said that it is not necessary, it can still get this result in the time of simple problems.

Of course, there are still discrepancies between this explanation and reality, at least this cannot be said to be an exhaustive list.

But no matter what, Lin Xiao's method is to make the problem of "how to unify quantum mechanics and relativity" be solved through a program within a certain period of time, just like a special value of the P=NP problem.

As for how to prove P=NP, Lin Xiaoke still has no solution.

Next, watching the program start to run, Lin Xiao could finally relax temporarily.

Although I don't know how long it will take to solve this problem, maybe tomorrow, maybe a week later, it is not impossible to wait until a year.

But at least, as far as today is concerned, it will probably not be completed.

……

In the following time, Lin Xiao went to share his good news with Witten.

Witten was very shocked, "You actually found a polynomial calculation formula that can test the unified quantum mechanics and the theory of relativity?"

Lin Xiao smiled and said, "Yes."

"Oh my God." Witten couldn't help but shook his head, he was very shocked by this matter, he would never have thought that the unification of quantum mechanics and relativity would actually come out of a computer program , This kind of development made him feel unexpected, like a joke.
