From failed candidate to chief scientist

Chapter 130 String Theory

"Here, Lin Mo, how about we change it?"

Shan Gang was a little panicked.

As we all know, string theory is not particularly difficult to study.

A basic point of string theory is that the basic units of nature are not point particles such as electrons, photons, neutrinos and quarks, but very small linear "strings", similar to rubber bands.

The only difference between it and the particle type is the difference in the frequency at which the string vibrates.The different vibrations and movements of the string produce various different elementary particles.

This sounds very fantasy, because it is equivalent to telling you that all the real substances you see are actually vibrated by extremely small rubber bands.

Of course, the actual string theory is not like this. If you have a deep understanding of string theory, you will understand that the so-called string is a manifestation of energy.

In the theoretical model, the most basic unit that makes up all matter is a small "energy string". Basic particles as large as interstellar galaxies and as small as electrons, protons, and quarks are all composed of this "energy string" occupying two-dimensional space and time. "Composed of.Particles are different manifestations of energy line vibrations.

Theoretically speaking, string theory is the most promising theory to unify the fundamental particles of nature and the four forces of interaction.

It can solve the two seemingly incompatible major theoretical problems in physics, quantum mechanics and general relativity, and unify them into a "theory of everything" for the entire universe.

String theory sounds very advanced and seems to be the end of physics, but in fact, although string theory has made great progress and established many theories, with the full dedication of countless scientists, string theory has become more and more rich and perfect. , but so far, string theory still cannot be demonstrated experimentally.

This makes string theory seem like a castle in the air, flashy and unrealistic.

Therefore, many current studies on string theory remain at the theoretical stage, and more research is conducted using mathematical methods. This is why problems in the physical field of string theory appear in mathematical problems.

The origin of string theory can be traced back to 1968. When Gabriele Veneziano was looking for the formula for the strong force that describes the nucleus, he found the 200-year-old Euler's formula. Using Euler's formula He described the strong force he sought to solve.

Then Leonard Su Shikan further understood this formula as a small elastic "line segment" that can twist and shake like a rubber band, that is, a string, and later developed it into "string theory".

It is an old tradition for physicists to use mathematical means to solve physical problems.

Otherwise, scientists in the Middle Ages were often both physicists and mathematicians.

"No, that's it!"

Lin Mo shook his head, rejecting Shan Gang's suggestion to change.

"But this difficulty..."

String theory is indeed very attractive, because every step you take is making history. However, it is not easy to take this step. No matter how many people invest more than ten years in research, they may not be able to take this step.

"It's okay. Take your time. How can you be afraid of difficulties when doing research? At worst, it's better to just do a long-term project."

"Ok."

"Well, Gangzi, please write down the project approval reports for these two projects. Marina is not familiar with our process after all."

Shan Gang nodded and made an Oak gesture.

So when Tian Fangyi arrived at the Mathematics Research Center, he was ready to tell Lin Mo that the research he and Zhang Qihua had done according to the research plan given by Lin Mo had been completed, the paper had been written, and the good news that the Mathematics Research Center had officially upgraded to a provincial laboratory When I was in ink, I received two project approval reports handed over by Shan Gang.

Tian Fang was a little confused for a moment.

"The Bockner-Ries multiplier problem? The integrability problem in the AdS/CFT correspondence conjecture?"

Tian Fangyi can still understand the previous project approval. After all, the Fourier transform and the Kakeya conjecture have been solved, and it is a matter of course to solve the Bockner-Ries multiplier problem.

But the AdS/CFT issue...is this research that our mathematics research center can touch upon at this stage?

In Tian Fangyi's view, such cutting-edge issues about string theory should be studied by large international institutions and top scientists, rather than a small Mathematics Research Center of Dongshan University, which is full of calculations and only has five people. Issues that should be studied in individual provincial mathematics laboratories.

Tian Fang opened his mouth, trying to dissuade Lin Mo, but when the words reached his lips, Tian Fang swallowed them back.

Because based on his understanding of Lin Mo, Lin Mo wouldn't listen to him even if he told the truth. Isn't that what Kratz suspected at the beginning?

And the final result was that he was slapped in the face. Lin Mo not only solved Kratz's conjecture, but he also did it in a short time.

In the end, Tian Fangyi could only attribute this to a genius like Lin Mo, which cannot be inferred using common sense. What if someone could have done it?Will you not be the one getting slapped in the face then?
Tian Fangyi summarized one thing, that is, whatever Lin Mo advocates, give full support and that's it.

So Tian Fang swallowed back his words of dissuasion.

"Ok."

Tian Fang agreed happily.

"By the way, Lin Mo, the interview is scheduled to start at 9 a.m. tomorrow, in the conference room next door. Don't forget it."

"Interview? What interview?"

Lin Mo was at a loss.

"Regarding the interview of talents in the field of mathematical statistics and probability theory, we have invited all the candidates to come and interview them together tomorrow."

"Oh well."

"By the way, there is one more thing..."

Tian Fang was ready to leave when he suddenly thought of something else.

"what?"

"Something about that algorithm."

"algorithm?"

"That's the Holt Laboratory. They have cashed in the $100 million reward for Kratz's conjecture. Didn't you agree to help them sort out an algorithm? They have already promised to pay an additional $100 million. cost."

"Oh, I remembered, no problem, I happen to be free these two days, I will take the time to do it, don't worry."

As soon as Tian Fang got the answer he wanted, he turned around and left with satisfaction.

Algorithm... Lin Mo thought for a while and finally approached Jiang Fanjun.

"Teacher Jiang, there is a project you want to do?"

"what?"

Jiang Fanjun was a little confused. Are the projects of Dongshan University Mathematics Research Center so rich?I haven't finished the project on NS equations at hand, so you are arranging another project for me?

Moreover, I am not from your Mathematics Research Center. Is it really okay for you to arrange work for me like this?
Jiang Fanjun came to help in order to repay Lin Mo's favor, and also because he could participate in the NS equation research project. It was purely voluntary labor, but now Lin Mo is...

Do you regard him as one of your own at the Mathematics Research Center?
