Chapter 275 String Theory (Addition 4)

Chapter 276 String Theory
The International Union of Mathematicians Conference ended with warm applause.

Qin Yuanqing returned to Shuimu, looking at the first-year freshmen who started military training under the guidance of instructors, Qin Yuanqing was full of pride in his heart. This is another batch of national talents. They will enjoy the best educational resources here, and after graduation Make your own contribution to national construction.

According to the latest statistics, 3300% of the 10 undergraduates who have just graduated choose to study abroad, 60% of the students choose to continue their studies, and only 30% of the graduates choose to work.

And some of these 30% of graduates choose to take the civil service examination to enter the official career, and only a very small number of students choose private enterprises for employment.In response to that sentence, if you are dissatisfied with any aspect, you can personally participate in and transform it.

When President Chen participated in the meeting of university presidents, he made a work report. He reported that Shuimu national defense graduates filed application reports and went to the frontier defense. Many graduate students and doctoral students gave up their high salaries to go to the west after graduation. With his chest in his arms, Mizuki's ideological education has achieved great results.

Qin Yuanqing is very happy to see that Mizuki students are adhering to their original aspirations and contributing to the country's construction. After all, isn't the mission of universities to cultivate talented talents for the country?

As in the past, all the military training will be transferred to the barracks on September 9st, but instead of being alone, I will share the same barracks with Yanda University and will compete in the barracks.

Watching the rest period, under the guidance of the officers, the freshmen sang military songs, such popular songs as "Green Flowers in the Army", "Battle Song of a Strong Army", "The Motherland Will Never Forget" and so on, resounded through the campus and became the The beautiful scenery of the campus at that time.

Qin Yuanqing thinks this kind of military training is pretty good. Why do so many teachers oppose military training and say that military training takes too long to waste time? Qin Yuanqing thinks that military training is the most precious wealth in life, and it is a rare patriotic education.

"Father~~" Qin Yuanqing had just returned home, and the baby girl who was playing in the yard saw Qin Yuanqing all of a sudden, and couldn't care less about playing with the sand, she cried childishly, opened her hands and trot towards Qin Yuanqing come over.

Only 1 year and 3 months old, the little girl is running very fast, and she can talk a lot. She can be called grandpa, grandma, and uncle. She is also very smart, and she will gesture or point at things she can't speak.

"Baby girl, where's mother!" Qin Yuanqing picked up the baby girl, squeezed her face, and asked.

"Mom, cook!" said the precious girl.

"Smelly brother, you can't play with my toys!" Then the girl yelled when she saw the brat playing with her forklift.

"I'm not a stinky brother, I'm an older brother, and you're a younger sister!" The stinky boy also learned to speak at this time, and he was already very slick.

"Father, say I'm an older sister and you are a younger brother!" The precious girl looked at Qin Yuanqing with eyes that seemed to be able to speak.

"Nonsense, Mom said I'm an older brother and you are a younger sister!" The brat retorted.

"I'm my sister!"

"I am brother!"

"Dad said it!"

"Mom said it!"

Qin Yuanqing looked at the pair of dragon and phoenix twins, where did the legendary loving family go?How come they started making noise before they could speak, and now they are making noise.

Headache!

nerve-wracking!
Qin Yuanqing went in with a child in one hand. Qin Yuanqing didn't remember who was older and who was younger. The two children were born 1 minute apart. How could he remember who came out first? Even the time written by the nurse was exactly the same.

The result is that Qin Yuanqing said that the precious girl is the elder sister and the brat is the younger brother.Jing Tian once told the brat that he is the elder brother and the precious girl is the younger sister.

The two quarreled so often.

After entering the room to wash the children's hands, I saw my wife cooking in the kitchen. After becoming a mother, she unknowingly practiced her cooking skills. She thoroughly researched what recipes are suitable for children.

In his wife, Qin Yuanqing saw what it means to be a mother, no matter what major you are studying, no matter how much you like to play and yearn for Western life before marriage, after having children, the Chinese female genes engraved in your bones will burst out Come out, no matter how hard or tired you are, you are willing to pay for your children.

Qin Yuanqing felt that half of his honor was due to the woman behind him!Not only family affairs, but also some meetings of the WeChat group were all held by her.

Qin Yuanqing thinks this is pretty good, with the warmth of a family, it would be great if it can continue like this!It's a pity that the young lady is not reconciled to leaving the film like this, and has always wanted to give in again. According to her, she also wants to make some achievements in her own field, instead of becoming a housewife early.

Although he was unwilling in his heart, Qin Yuanqing still chose to respect it!
If it were him, Qin Yuanqing would not be willing to let him concentrate on being the man of the house.

"I'm going to Europe in a while, CERN has a high-energy physics experiment, I need to participate in it!" Qin Yuanqing said during the meal.

After Wei Teng told him about it, he received an official invitation from CERN the next day, and Qin Yuanqing also agreed to participate in this experiment.

"En!" Jing Tian nodded to show that he knew: "My mother will come back in a few days, and the child will be handed over to my mother!"

"Have you mastered your mother's ideological work?" Qin Yuanqing paused.

It’s okay to want to act, but the child must be taken care of by someone after all. After all, I still feel a little worried about taking care of the nanny. Qin Yuanqing’s family members have language barriers in their hometown, so the only hope is Mama Jing. Papa Jing is completely absent in the Northeast system. hope.

But Mama Jing also has her own business. After all, there is a huge company there, and it has been in business for more than ten years. It doesn't mean that you can give up if you give up.

"Just help me take it for a few months, and then figure out a way after filming this drama!" Jing Tian said.

Qin Yuanqing nodded slightly. She participated in the investment of the movie "Ghost Blowing the Lantern: Finding the Dragon", and then won the number one female lead.

After Qin Yuanqing stayed in the capital for a period of time, as the CERN experiment time approached, Qin Yuanqing took his three graduate students and doctoral students who were studying theoretical physics and two researchers from the High Energy Research Institute of Mizuki University on the plane and headed to Switzerland!

In first class on the plane, everyone chatted about string theory.

The so-called string theory mainly tries to solve the contradiction between the seemingly incompatible two major physical theories, that is, quantum mechanics and general relativity, and intends to create a "theory of everything" that describes the entire universe, which is the legendary "theory of everything". Grand Unified Theory".

Speaking of which, the discovery of this theory has a lot to do with mathematics.

Venecino, who works at CERN, originally wanted to find a mathematical formula to describe the strong force in the nucleus. As a result, he found the 200-year-old Euler's formula in an old mathematics book and wrote Surprisingly, it was found that this formula could successfully describe the strong force he wanted to solve.

Under such a coincidence, the prototype of string theory was born!
Including the later Bose string theory, superstring theory, and the M theory of "unifying the world" proposed by Witten, all developed on this basis.

Establishing a "grand unified formula" to describe everything in the universe is almost the ultimate goal of theoretical physics.

Of course, in Europe and the United States, string theory is a research hotspot and the frontier of physics. It has achieved great results and produced many famous scholars.In China, this is a bit embarrassing. The development of string theory can be said to belong to the world's third-rate level.

In China, the theoretical physics community simply regards string theory as a 'mathematical freak' and is not very willing to accept it!
Is it surprising that it is a topic of theoretical physics, but the theoretical physics community is not keen on studying it but regards it as a freak, while the mathematics community is open to string theory.

"Academician Qin, what's your opinion on string theory?" Gao Bo, a researcher at the Institute of High Energy Research, suddenly asked.

"As for the development of string theory, I quite agree with Yang Lao's point of view. Physics is a science based on experiments. A theory that cannot be verified in experiments has only mathematical representations, and its value is very limited." Qin Yuanqing After a little thought, he said: "The core idea of ​​string theory points out that the basic unit of nature is not point-like particles such as electrons, photons, neutrinos, and quarks, but very small one-dimensional strings. And in nature All the fundamental particles in the universe are produced by the vibration of strings. But so far our understanding of matter is still at the level of microscopic particles, and no one has really seen the existence of that string. Supporting these hypotheses are only some observations. It's like a beautiful mathematical formula."

The development of string theory is also in a very embarrassing situation in the world. It is almost Witten who initiated the first revolution of string theory and the second revolution to promote the development of string theory. Confirmation, this is a bit embarrassing. After so many years, CERN has also started many experiments, but it is impossible to find relevant evidence.

It is also true that Witten has been unable to win the Nobel Prize in Physics for a long time.

CERN's facilities and technical strength are absolutely top-notch in the world, with a hugely expensive collider, the most advanced computers, and the best researchers, but there is no way to advance the pace of string theory in experiments.

Yang Mills theory cannot win the Nobel Prize in Physics because although the relevant particles have been confirmed in physical experiments, there is no way to prove it from a mathematical point of view in the mathematical world, that is to say, the Yang Mills equation cannot be proved to be true. fake.

But string theory is just the opposite. The mathematical community has reached a consensus on it, so Witten won the Fields Medal.However, in terms of physical experiments, it has been delayed, so many physicists have always thought that it is just a theory that looks beautiful, but in fact it is a castle in the air, which is not useful, it is a mirage.

Sometimes it’s not good to have a theory that is too advanced. That’s it. In Qin Yuanqing’s view, if CERN’s equipment does not undergo major upgrades, it will be very difficult to achieve results on the existing basis, unless it is Good luck, the blind cat met a dead mouse, otherwise Witten would never have won the Nobel Prize in Physics for his string theory in this life.
