Rule department scholar

Yan Yi is a lecturer at a university. She graduated with a Ph.D. and has been working for one year.

Whether it is education, work, or appearance, they all meet Liu Chengjie's expectations. In addition, when he first came to the laboratory, he was cautious and cowardly, which was enough to make Liu Chengjie's heart flutter.

but……

Zhao Yi looked very upset, not because he had any thoughts about Yan Yi, the main thing was that Yan Yi came to work on the first day.

The purpose of recruiting new people in the laboratory is to increase manpower and prepare for project research, not to find a girlfriend for Liu Chengjie.

This guy is too fast!

Zhao Yi took a deep breath and asked Zhang Wei, "Sister Zhang, how much money do we have left?" He was referring to the shared funds of the laboratory.

The common funds of the laboratory are the remaining funds for the project, as well as the bonus given for the completion of the project, all of which can be freely used.

Zhao Yi's laboratory has completed the rheumatoid arthritis project, and the settlement of the previously completed project can be said to be the richest in the institute.

Zhang Wei said, "It's about 260 million, do you want to use it?"

These funds are free to purchase equipment for the laboratory.

If Zhao Yi had a thicker face and a darker heart, and even put some of it in his pocket, no one would say anything.

Zhao Yidao, "I was thinking, the project has already been applied for, and we just need to wait for the approval. We should also do some preparatory work."

He stood up and paced around, as if giving a speech, "What is the most important thing in the laboratory? Not the equipment, but the people."

"Every one of us is very important, and everyone will contribute to the completion of the project. Only by working harder can we complete the project faster and better..."

"So I was thinking, before the project is approved, we should motivate everyone!"

"I've decided. Each person will be given a bonus of [-]. Teacher Yan is a newcomer and hasn't officially started working yet, but he is also a member of us. Let's give... [-] too!"

Yan Yi was suddenly surprised, and she immediately said, "I don't need it."

"Don't push it, I have the final say on this laboratory." Zhao Yi said forcefully, and then looked at Liu Chengjie, "However, I don't think Brother Liu will need it anymore. I think he is already very motivated."

He walked over and patted Liu Chengjie on the shoulder and said, "Come on, Brother Liu, I like you!"

"..."

"..."

Zhang Wei and Ai Lixin burst out laughing together.

Yan Yi's face turned red, and she didn't know whether to smile or not.

With a bitter face, Liu Chengjie said, "Professor Zhao, brother Zhao, our bonus..."

"come on!"

Zhao Yi gave Liu Chengjie a thumbs up, "You can do it without a bonus!"

"..."

Zhao Yi was just making a little joke with Liu Chengjie.

AIDS-related projects have been applied for, just waiting for approval.

During this time the laboratory was very free, and Zhao Yi didn't need to go there every day, so he simply re-invested in 'finding inspiration'.

Zhao Yi felt that the inspiration he got from the fish before was very valuable, but he has not yet found out where the specific value is reflected.

Walking around the school, he thought of the word "physics", "Since it's physics, maybe I should go to...physics class?"

In Yanhua University's biological science major, physics is studied in the freshman year, and the main subjects in the sophomore year are chemistry and biology.

It's a pity.

Zhao Yi simply went directly to the teaching building of the Faculty of Science, and walked around to see if there was a classroom where physics was being taught.

In the big classroom on the right hand side of the third floor, he really found a physics class.

The way is very simple -

He saw a familiar teacher, Professor Gao Yihua.

Zhao Yi glanced at the back door, walked in cautiously, and sat silently in the last row.

There were a few students in the last row, who thought they were late when they saw someone coming in, and a tall, skinny guy with a short cut reminded him, "Dude, you're late, the roll call is over."

"Ah."

Zhao Yi nodded towards him friendly.

The tall and thin man was startled immediately, and he stretched out his voice in a low voice, "Zhao———"

"Don't disturb the teacher's class." Zhao Yi also reminded.

The tall and thin man immediately told the people next to him, and the people next to him told the front row, and many people looked over immediately. Fortunately, the students were still afraid of disturbing the teacher in class, so no one yelled directly.

on the podium.

When Gao Yihua saw the situation in the back row, he couldn't help frowning. He thought that some students were late. He didn't like the phenomenon of being late. .”

That is, 'being late equals not coming'.

This requirement is still very strict. Some students simply did not come when they found out that they were late.

Gao Yihua didn't pay much attention to it, so he continued to devote himself to the course. He was a sophomore in the Department of Mathematics of the Faculty of Science. The physics course of the mathematics department was more profound than that of the biological science major. A lot of knowledge was not available in the physics course of biological science.

Gao Yihua was also very involved in the lectures, which he thought was progress.

Last year he was in charge of the physics class of the biological science major, but Zhao Yi was always sitting in the audience. This semester, he simply applied to lead the mathematics department, and he still took the three majors. There are many classes every week, but he It feels very comfortable, because there is no blinking student in the audience.

Gao Yihua has let himself go a little bit, and occasionally improvised during lectures.

For example, now.

Gao Yihua was talking about the introduction of quantum physics, but he jumped to domestic physics research for some reason.

He mentioned Zhao Yi.

"Zhao Yi used a computer-biased method and used particle collision experimental data to find the signal of a new example."

"This is an amazing achievement, because previous top physicists asserted that the strength of the test collision experiment was not enough to support the discovery of the Higgs particle..."

"The new particle discovered by Zhao Yi is probably the Higgs particle..."

Gao Yihua's lecture on letting go of himself was really interesting. He later talked about the research of the Chinese Nobel Prize winner Yang Zhenning - the law of parity non-conservation.

"Parity."

"This word is very professional. It describes the multiplicative quantum number of the transformation properties of particles under space inversion. It is quoted as P. It has only two values ​​​​+1 and -1."

"If the wave function describing a particle changes sign under the space inversion transformation r→-r, the particle has odd parity P=-1, and if the wave function remains unchanged under the space inversion, the particle has even parity Say P=+1..."

After explaining a lot of content that was difficult to understand, Gao Yihua switched to the simple mode, "Parity is not conserved, it can be understood as follows: there are two mirror images of each other, the driver of car A sits in the left front seat, the accelerator pedal The pedal was near his right foot; while the driver of Car B was seated in the front right seat, the gas pedal was near his left foot."

"The driver of car A turns the ignition key clockwise and presses on the gas pedal with his right foot; the driver of car B does the exact same thing, just swapping left and right."

"So, how will Car B move?

"Perhaps most people would think that the two cars should be moving forward at exactly the same speed, but in the particle world, car B will be traveling at a completely different speed and not necessarily in the same direction!"

"This is parity violation!"

Gao Yihua's lectures were completely substituted into it, and he found that many of the students understood, and even felt a little proud.

He scanned the classroom, his eyes suddenly stopped.

last row……

That figure with its chin propped up and looking at it seriously seems a little familiar?

"Zhao Yi!"

Gao Yihua's eyes widened immediately, his mouth half-opened and he couldn't close it, his face was no longer proud, but tears were about to flow.

"why……"

"You are a sophomore and I am also teaching the mathematics department, why can I still see you in the classroom?"

"Brother..."

"Can't you let me go!"

Chapter 300 The Microcosm: Particle Boundary Theory

"Zhao Yi, why did you come to the classroom? This is obviously a classroom of the mathematics department..."

"Why is he here!"

"Did you listen to the whole class? By the way, it seems that a student came in through the back door just now. Could it be him..."

Gao Yihua's mentality collapsed.

In the past few years, he taught physics classes in the School of Life Sciences. He did not expect to meet a "super student" Zhao Yi. Not only was he a top-notch mathematics talent, but he also went to CERN to test his skills. The experimental site simply solved the problem of discovering new particles.

With this achievement alone, he is recognized as the world's top physicist, and even insiders know that he uses more computer methods.

What does it matter?Results are what count.

Even if you use completely irrelevant biological knowledge, as long as you can solve important physical problems, your physics level will definitely be recognized.

So Gao Yihua felt unable to attend class.

There was an internationally renowned physicist in the class. He didn't know how to give lectures, and he barely survived the rest of the courses. Gao Yihua was really depressed. He simply applied to be a teacher in the Faculty of Science, which was far away from the Faculty of Life Sciences. It would be best to have no connection at all.

This semester, Gao Yihua felt too relaxed.

Whenever he is in the classroom, he can always think of the experience of the last semester, and then he glances at the classroom and feels at ease.

just now……

It seems to be back again?

"That guy!"

"here we go again!"

Gao Yihua didn't know how to react, he froze on the podium for a while, and found the strange eyes of the students, and he came back to his senses, knowing that the normal class should not be affected because of Zhao Yi's arrival.

It's not that he is so dedicated, but that Zhao Yu sat quietly in the back row and didn't affect other people.

As a teacher, he certainly can't affect the progress of the course because of his mentality.

So go ahead!

Gao Yihua gritted his teeth hard, pretending that Zhao Yi didn't exist, or didn't see anything, "He's not here! He's not here! He's not here! He's not here..."

That of course didn't work.

Gao Yihua's mentality was still affected. His face was no longer relaxed, nor was he free and easy. Instead, he became much more serious. Continuing with the content just now, he subconsciously spoke in more detail and depth.

"It doesn't matter if the other students understand or not... You must not be looked down upon!"

That's what Gao Yihua thought, as if he was undergoing a knowledge review.

……

Backstage.

Zhao Yi listened carefully with his chin resting, and fell into thinking following Gao Yihua's explanation. Of course he knew about the non-conservation of parity.

It was the research of Yang Zhenning, a famous Chinese physicist and Nobel Prize winner in physics.

Parity violation means that in the weak interaction, the motions of matter that are mirror images of each other are asymmetric.

This study was later verified by Wu Jianxiong with cobalt 60.

Before 1956, the physics community always believed that all things in nature are mirror-symmetrical, whether it is a strong force or a weak force, they will all conform to the principle of mirror symmetry.

The understanding of "parity" is that the mirror image of a particle is exactly the same as its own nature.

In 1956, the physics community discovered that theta and t mesons had exactly the same spin, mass, lifetime, and charge. Most people believed that they were the same kind of particle, but two π mesons were produced when theta meson decayed, and two π mesons were produced when the t meson decayed. 3, which means that they are different kinds of particles.

Contradictions arise.

This year, Li Zhengdao and Yang Zhenning, after in-depth and meticulous research on various factors, boldly asserted that: t and θ are exactly the same particle (later called kaon), but in the environment of weak interaction However, their laws of motion are not necessarily identical.

To put it simply, if these two identical particles look at each other in a mirror, their decay methods are actually different inside and outside the mirror.

In scientific language, the "θ-t" particle is not parity-conserved under the weak interaction.

At the beginning of the discovery, the "θ-t" particle was only regarded as a special exception, and people were still unwilling to give up the parity conservation of the overall microscopic particle world. The experiment verified the "parity non-conservation".

Since then, "parity non-conservation" has been truly recognized as a basic scientific principle with universal significance.
