Xueba: I study hard in the wasteland world

The European Organization for Atomic Energy Research, also known as the European Particle Research Institute, often referred to as CERN, is the world's largest particle physics laboratory and the birthplace of the Internet.

Founded on September 29, 1954, it provides scientists from around the world with scientific research tools on how matter is formed and the forces between matter.

There are more than 4,000 full-time employees working here, in addition to approximately 6,500 scientists and engineers from 80 nationalities, representing more than 500 university institutions, conducting experiments at CERN.

It can be said that half of the physicists and mathematicians of human civilization are gathered here!

At the beginning, there were only 12 signatory sponsors of the European Organization for Nuclear Research. Now the membership has increased to 25 member states, including of course China. As a new beacon of human civilization, China is now the largest "funder" of the organization. "!

Although Su Yu is a Nobel Prize winner in physics, his achievements are in the field of materials science, which are still two branches far away from high energy physics.

But even so, the European Atomic Energy Agency still expressed a very warm welcome to Su Yu.

"It's really good!"

Standing in front of the CERN headquarters, Su Yu nodded and took a photo in front of the monument to the "Origin of the Internet."

Yes, the Internet was not born in the United States, but was born here. At the beginning, it was just to enable better communication and better data analysis for CERN's scientific research staff.

"Professor Su, please!"

In order to welcome Su Yu's arrival, Professor Bilaire Goddard, the director of CERN, deliberately learned a few Chinese sentences and spoke to Su Yu in Chinese with a smile.

"Oh, Professor Bilaire, your Mandarin is very good!"

Because she knew that the old professor was from France, Su Yu also responded politely and praised the old professor in less fluent French.

"Hahaha!"

Su Yu and Professor Bilaire Goddard walked into the hall of CERN while complimenting each other!

A few years ago, when Su Yu saw such a high-end and advanced laboratory, she would be as surprised as "Grandma Liu entered the Grand View Garden", very unpromising.

But in recent years, various high-end and advanced laboratories in China have sprung up like mushrooms after a rain. There are really a lot of them.

Especially the "NPU Fruit Candy New Materials Laboratory", with Su Yu's constant donations, this laboratory is very luxurious.

Therefore, Su Yu was very calm when she walked into the laboratory.

Regarding CERN, Su Yu first became aware of it when she read the novel "Angels and Demons" by American writer Dan Brown when she was in middle school.

Later, he went to college and became a pure science and engineering man. All physics documents and various textbooks were from CERN. This was once the "holy place" in Su Yu's heart.

Su Yu felt quite happy to be able to work in the once holy place.

Next, Su Yu began his visiting life at CERN, where he would stay for more than half a year until scientists from all over the world completed the preparations for the large collider experiments and completed the experiments.

After staying here for only a few days, Su Yu quickly became familiar with the life and study here, and started a life of "CERN" and "home" every day!

On an ordinary Monday, Su Yu, who had spent the whole weekend in the villa, drove his Ferrari into the parking lot of CERN and started a new week of study tour work.

When walking into an internal teaching and research room, Su Yu was attracted by a line of calculations on the blackboard in the teaching and research room:

Linear transformation is the linear mapping M:V→V from M linear space v to itself,

For ψu, v∈V, ψp belonging to P all satisfy:

(1), M(u+v)=M(u)+M(v)

(2), M(pu)=pM(u)

The formula was very complicated, but Su Yu saw at a glance that it was a formula related to "group theory". Su Yu was attracted and walked into the teaching and research room.

As soon as Su Yu entered the teaching and research room, the physicists and mathematicians from all over the world who were sitting in the teaching and research room said hello to Su Yu.

Su Yu nodded and replied to their greetings. She crossed her hands on her chest and thought seriously about the calculations on the blackboard.

Looking at Su Yu coming in, the professors in the teaching and research office did not have much fluctuation. They continued to lower their heads and do their own calculations.

They need to solve the equation on the blackboard, because this equation is related to the preparations for the Large Collider Laboratory.

As for Su Yu being able to solve this equation, no one in the teaching and research department had this idea.

Of course, if what is listed on the blackboard is a material science or partial differential equation, everyone will definitely believe that Su Yu can solve it, because Su Yu, who invented the "fruit candy screen" and "proven the NS equation", is a material science and World authority in the field of partial differentials.

But this is a "group theory" problem related to high-energy physics. No one has heard of Su Yu's achievements in the field of high-energy physics.

But after Su Yu thought about it, he raised his eyebrows and showed a happy smile on his face: He found a way!

"Can I try it?"

Su Yu pointed to the topic on the blackboard and asked the professors in the teaching and research office.

Su Yu's question made all the professors present raise their eyebrows. This is a problem that has troubled the entire CERN for more than half a year. Su Yu just wanted to try it after looking at it for so long?

The image of this young Su Yu to the world has always been modest and polite, but today everyone was stunned. Unexpectedly, he was like most young people, with a sense of overestimation!

In the teaching and research office, a physics professor from Zhejiang University in China hurriedly reminded Su Yu: "Professor Su, this question is a bit difficult!"

Su Yu smiled and said to everyone in English: "I am a layman. If I make a mistake, please don't laugh at me!"

After walking up to the blackboard, Su Yu took a deep breath, picked up a piece of chalk, and began to perform calculations on the blackboard:

".

It is known that M is a linear transformation of the complex space. We can find the eigenvalue λ by solving its eigenequation |MλM|=0,

The eigenvalues ​​may be degenerate, but they will never have no solution. At least one p∈p can be found that satisfies the above equation.

Then the equation |uyu|=0 actually shows that the matrix umt is a singular matrix.

The determinant value is zero, which means that if we treat each column of it as a vector, that is |ulv|=

"

With his mind completely open, Su Yu's calculations instantly became extremely smooth. After simple logical processing, the knowledge accumulated in his mind was outputted like silk.

Su Yu has been busy with various tasks recently. It has been a long, long time since Su Yu experienced this feeling of concentrating and studying a problem wholeheartedly and smoothly.

This feeling made Su Yu feel ecstatic and addicted!

Mario Sloan in the teaching and research department is a professor of physics and mathematics from Harvard University. He has heard of Su Yu’s name. The mobile phone he uses is also a Warwick mobile phone equipped with a fruit candy screen, but after all, he is in the same field as Su Yu. Yes, I don’t have a cold feeling towards the young Su Yu.

Especially today, the young Su Yu actually wanted to challenge the blackboard problem that troubled all the world's top physicists and mathematicians present. His impression of this young Su Yu was even worse!

"He, my God, he, he actually used this method! And, there doesn't seem to be any problem!"

And when he looked up and saw Su Yu's calculations line by line on the blackboard, he was stunned, like a lustful man watching a graceful goddess taking off her clothes, stunned!
