Chapter 276 String Theory

The International Union of Mathematicians Congress came to an end with warm applause.

Qin Yuanqing returned to Shuimu and looked at the freshmen who had begun military training under the guidance of instructors. Qin Yuanqing's heart was full of pride. These were another group of national talents. They would enjoy the best educational resources here, and then after graduation

Make your own contribution to national construction.

According to the latest statistics, 10% of the 3,300 undergraduates who have just graduated choose to study abroad, 60% of students choose to continue their postgraduate studies, and only 30% of graduates choose to find employment.

And some of these 30% 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. As that saying goes, if you are dissatisfied with any aspect, go and personally participate in it and transform it.

When President Chen attended the meeting of university presidents, he made a work report, reporting that Shuimu defense students had applied for border defense after graduation. There are many people on the front line. Many graduate students and doctoral students gave up their high salaries and went to the west after graduation. President Chen took a photo

I can honestly say that Shuimu's ideological education has achieved great results.

Qin Yuanqing was very happy to see Shuimu students adhering to their original aspirations and contributing to national construction. After all, the mission of colleges and universities is to cultivate talented people for the country.

As in the past, military training will all be transferred to the military camp on September 1st, but instead of just being on your own, you will share a military camp with Yanda, and you will compete in the military camp.

During the break, under the guidance of the officers, the freshmen sang military songs, such as "Green Flowers in the Army", "Battle Hymn of a Strong Army", "The Motherland Will Not Forget" and other popular songs, resounding throughout the campus, becoming this

The beautiful scenery of the campus.

Qin Yuanqing thinks that this kind of military training is quite good. Why are there so many teachers who oppose military training and say that military training is too long and a waste of time? Qin Yuanqing feels that military training is the most precious wealth in life and a rare patriotic education.

"Dad~~" Qin Yuanqing had just returned home. His precious daughter, who was playing in the yard, also saw Qin Yuanqing with sharp eyes. She didn't care about playing in the sand. She cried out in a milky voice, opened her hands and trotted towards Qin Yuanqing.

come over.

At only 1 year and 3 months old, the little girl is running very smoothly and can talk a lot. She can call her grandparents and uncles. She is also very smart and can gesture or point when she doesn't know how to speak.

"Baby girl, where's the mother?" Qin Yuanqing picked up the baby girl, pinched her cheeks, and asked.

"Mom, cook!" the baby girl said.

"Brother, you can't play with my toys!" Then the daughter saw the brat playing with her forklift and shouted.

"I'm not a stinky brother, I'm a brother and you are my sister!" The stinky boy also learned to speak at this time, and his speech was already very smooth.

"Dad, say I am the elder sister and you are the younger brother!" The precious girl looked at Qin Yuanqing as if her eyes could speak.

"Nonsense, mom said I am the brother and you are the sister!" the brat retorted.

"I'm my sister!"

"I'm my brother!"

"Dad said it!"

"Mom said it!"

Qin Yuanqing looked at the twins, where had the legendary loving family gone? How come they started quarreling before they could even speak, and they are quarreling now.

Headache!

Nervous!

Qin Yuanqing went in with a child in one hand. Qin Yuanqing couldn't remember who was older and who was younger. The two children were born one minute apart. At that time, he couldn't remember who came out first. Even the time written by the nurse was exactly the same.

The result was that Qin Yuanqing said that his precious daughter was his sister and that brat was his younger brother. Jingtian once told the brat that he was a different person and that his dear daughter was his younger sister.

The two of them quarreled so often.

When I entered the room to wash the children's hands, I saw my wife cooking in the kitchen. After becoming a mother, she had unknowingly developed her cooking skills. She had thoroughly studied the recipes suitable for children.

In his wife, Qin Yuanqing saw what it means to be strong as a mother. No matter what major you studied, no matter how much you liked to play before getting married, or how much you yearned for life in the West, after you have 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 matters, but also some meetings of the WeChat Group were held by her.

Qin Yuanqing thinks this is quite good, with the warmth of a family. It would be great if it could always be like this! It's a pity that the young lady is not willing to die like this. She always wants to pay again. According to her, she also wants to make some achievements in her own field.

Come instead of becoming a housewife early.

Although he was unwilling in his heart, Qin Yuanqing still chose to respect him!

If it were him, Qin Yuanqing wouldn't want to be the head of the family.

"I'm going to Europe in a while. There is a high-energy physics experiment at Cern, and I need to participate!" Qin Yuanqing said while eating.

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

"Yes!" Jingtian nodded to show that he understood: "My mother will come back in a few days, and I will leave the child to my mother!"

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

It's okay if you want to act, but someone has to take care of the child after all. After all, it's still a bit uneasy to have a nanny. Qin Yuanqing's family members all have language barriers in their hometown, so the only hope is Jing's mother. Jing's father has no one in the Northeast system.

hope.

But Jing Ma also has her own business. After all, there is such a big company there and it has been running for more than ten years. This does not mean that she can just give up.

"Just help me take care of it for a few months, and then we can think of a solution after filming this drama!" Jingtian said.

Qin Yuanqing nodded slightly. She participated in the investment in the movie "Ghost Blowing the Lamp: The Secret of the Dragon" and won the lead female role.

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

In the first class cabin on the plane, everyone was chatting about string theory.

The so-called string theory mainly attempts to resolve the seemingly incompatible contradiction between the two major physical theories, namely quantum mechanics and general relativity, and to create a "theory of everything" that describes the entire universe, which is also known as the legendary "

Grand Unified Theory".

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

Venechino, who works at the European Center for Nuclear Research, originally wanted to find a mathematical formula describing the strong force in the nucleus. As a result, he found the 200-year-old Euler's formula in an old mathematics book, and

Unexpectedly, he found that this formula could successfully describe the strong force he wanted to solve.

Under such a chance coincidence, the prototype of string theory was born!

Including the later bochromatic string theory, superstring theory, and the "unifying world" m-theory proposed by Witten, they were 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 hot research topic and the frontier of physics. It has achieved great results and produced many famous scholars. But in China, this is a bit embarrassing. The development of string theory can be said to be at the third-rate level in the world.

In China, the theoretical physics community simply regards string theory as a ‘mathematical freak’ and is not very willing to accept it!

Isn't it surprising that it is obviously a theoretical physics topic, but the theoretical physics community is not keen on studying it and regards it as a weirdo, while the mathematics community is accepting and open to string theory.

"Academician Qin, what do you think of string theory?" Gao Bo, a researcher at the Institute of High Energy Research, suddenly asked.

"As for the development of string theory, I agree with Mr. Yang'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 thinking for a while, he said: "The core idea of ​​string theory points out that the basic units of nature are not point particles such as electrons, photons, neutrinos, and quarks, but very small one-dimensional strings. And in nature

All basic particles are produced by the vibration of strings. But so far, our understanding of matter still remains at the level of microscopic particles, and no one has really seen the existence of that string. What supports these assumptions are just some observations.

Like a beautiful mathematical formula.”

The development of string theory is also in a very embarrassing situation in the world. It was almost Witten who initiated the first revolution in string theory, and the second revolution promoted the development of string theory. However, great progress has been made in theory, but it has never been achieved in experiments.

Confirmation, this is a bit embarrassing. After so many years, Cern has also started many experiments, but can't find relevant evidence.

It is precisely for this reason that Witten has been unable to win the Nobel Prize in Physics.

Cern's facilities and technical capabilities are definitely the best in the world, with hugely expensive colliders, the most advanced computers, and the best researchers, but they are unable to advance the pace of string theory in experiments.

The reason why Yang Mills' theory could not win the Nobel Prize in Physics is because although the relevant particles have been confirmed in physical experiments, there is no way to prove it from a mathematical perspective in the mathematical community. In other words, the Yang Mills equation cannot be proved to be true.

Fake.

But string theory is exactly the opposite. The mathematical community has reached a consensus on it, so Witten won the Fields Medal. However, it has been lagging behind in terms of physical experiments, so many physics people have always thought that it just looks weird.

A beautiful theory, but in reality it is just a castle in the air, a mirage that only looks good but does not work.

Sometimes it is 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 a major upgrade, it will be very difficult to achieve results on the existing basis, unless it is

Fortunately, the blind cat meets the dead mouse. Otherwise, Witten will never be able to win the Nobel Prize in Physics for his string theory.
