I just want to be a quiet scholar

Chapter 532 M
Among the many "Kabila-Qiu Chengtong spaces", why choose the "Kabila-Qiu Chengtong space" whose absolute value of Euler's number is 6?
Witten did not explain the reasons for the choice in the first superstring theory revolution. With this "unproven inspiration", he directly led the second superstring theory revolution and proposed five different versions of superstring theory .

These five superstring theories exist at the same time and are compatible with each other, and Witten named it "M theory".

In the early 90s, Witten wrote in his thesis: "The meaning of M can be understood as Mystery (fan), Master (ruler) or Mother (mother) according to personal preference."

The academic world was shocked, and IMU was particularly excited, and awarded the Fields Medal to Witten as soon as the brain became hot.

Then, the third superstring theory revolution came, and British scientists proposed the concept of ten-dimensional supergravity theory.

But the problem is that no matter which school of thought it is, any scientist, including Witten himself, cannot give convincing evidence to explain the basic degrees of freedom of M theory.

The key question is that M-theory contains five compatible superstring theories. Which version of superstring theory describes the universe?What is the ultimate meaning of cosmic mathematics?
Mr. Hawking's intervention has led to a chaotic state of research in this field, with each group expressing their opinions and the situation becoming more and more complicated.

Because of the theoretical status of the Yang-Mie equation in high-dimensional space, Yang Zhenning and Mr. Mills also mentioned some remarks.

Superstring theory is not only a theory that unifies gravity and quantum mechanics, but also a theory of elementary particles.

There are electromagnetic force, strong force, weak force, and gravitation among elementary particles, so what kind of convincing theoretical system should be used to integrate the common principles hidden behind these four forces?

Even Einstein and Weyl have been dug out, and almost all the most famous physicists of the [-]th century have been directly or indirectly involved in the centuries-old debates of the superstring dispute, the rule of force, and the mysteries of the universe.

Although Witten sits on the throne of superstring theory No.1, there are many scientists who disagree with him, and scholars who question his theory will always question it.

"Children, I seem to have said the content of the textbook. What makes me feel lost is that the situation now is not much different from 30 years ago. We have not made a substantial breakthrough." Witten said, he This 70-year-old American scholar talked with a group of young Chinese scholars under the age of 40 about his masterpiece M-theory.

This set of theories seems to have really become a difficult mystery, and M should represent Mystery.

"If Mystery is solved, we will become Masters because it is Mother." Shen Qi said a rap, which was quite rhythmic.

"So?" Wei Teng asked, he knew that Shen Qi's mind would always hide new and exciting things.

"Edward, first of all, we must admit that the conclusion of the Cambridge team in the third revolution is correct." Shen Qi said.

"Who says no?" Wei Teng nodded.

Dr. Wei, who came back from Oxford, finally found a chance to speak: "Hey, those people in Cambridge are clever. They discovered that the ten-dimensional supergravity theory is not self-consistent with one-dimensional strings, but a two-dimensional membrane."

"Who says it's not." Witten smiled. There was a little-known story of falling in love and killing each other between him and the Cambridge boss Thompson.

"Edward, the M in your M theory has another hidden meaning, which is Membrane (membrane), right?" Shen Qi is well informed, he has heard the story of Lao Wei and Lao Tang falling in love and killing each other.

"Hmm." Wei Teng showed a bewildered smile.

The record in the official history of physics is that the American school headed by Princeton dominated the first and second superstring theory revolutions, and Witten is the leader who carries the flag and is the C position.

At the beginning of the third superstring theory revolution, the British school with Paul Thompson as the core actually denied most of the research results in the first and second revolutions.

This has also led to the chaotic situation of superstring theory's current hegemony.

But the description in the field history is different. There is obviously an affair between the C positions of the two camps, Witten and Thompson.

If the M in M ​​Theory stands for Membrane, Witten is a tribute to the pioneering work done by the British C position.

As the saying goes, 30 years in Hedong and 30 years in Hexi.

The international situation is changing, and the emperors take turns to sit.

Wei Teng and Thomson are now 80-21-year-old fathers. Hawking has left the world, and Mr. Yang lives in seclusion. The elders began to dominate the world.

Shen Qi is an undisputed C position among the younger generation of scholars. The C position in China put forward his point of view: "The two-dimensional membrane is discovered from the ten-dimensional supergravity theory, and can even be considered as a high-dimensional extension of the black hole solution." .”

"Schwarzzid's black hole solution is the solution of three-dimensional space, while Einstein's equation is any dimension and can be solved. An interesting and worthwhile topic is that the ten-dimensional space is distributed with a two-dimensional surface equal to the membrane, while Not dots and not strings."

"In other words, the question we urgently need to answer is, what will happen to the brane in ten-dimensional space after compacting the supergravity theory of ten-dimensional space into nine-dimensional space using a one-dimensional circle?" Shen Qi asked everyone.

"Yes, what will happen?" The rest of the Chinese scholars said in unison. Under the guidance of Shen Qi's logic, everyone seemed to be getting closer to the truth.

Rubbing their hands together in excitement, the faces of Ph.D.s in physics are glowing. Most of them will witness the solution of a century-old problem in physics within a few days after joining the center?

"Superstring theory is applicable to the space within nine dimensions, and in the ten-dimensional space, the membrane is considered as the basic unit of elementary particles. After the space is increased by one dimension, the basic unit is also increased by one dimension. The only constant is the quantum Mechanics, pay homage to Einstein, Schrödinger, Bohr and Heisenberg!" Shen Qi raised his arms and shouted, history and today are closely combined to point out the direction of the future, and the souls of the great physics gods lead everyone closer to the truth .

"Don't forget Fermi and Dirac!"

"And Planck and De Broglie!"

The doctors stood in a row and raised their right arms spontaneously and uniformly. This scene was very ceremonial.

Shen Qi added: "However, it is almost impossible to construct a theory with a two-dimensional membrane, which is also an important reason why superstring theory is in trouble."

thump!
The doctors fainted and all their ultimatums were activated, so you just tell us this?

Only Wei Teng was the calmest. He realized that what Shen Qi said was definitely not nonsense. After going around in a circle, he still needed to return to the original source.

Sure enough, Shen Qi said: "Tracing back to the source, I think the source of the problem is to thoroughly prove that the Kabila-Qiu Chengtong space with an absolute value of Euler's number of 6 is the best choice. Because a one-dimensional string moves in space The formed trajectory is a two-dimensional surface, and the topology of the two-dimensional surface is completely determined by the Euler number."

Willows and flowers brighten another village!
The doctors asked like chicken blood: "How to prove it? Professor Shen, do you have a plan?"

"Brothers, I've come to this point. Will the next thing be done by you?" Shen Qi recruited a group of returnee elites, not the melon-eaters watching. All problems were solved by Shen Qi. What is the use of this group of elite physics Ph.Ds?
