Chapter 335

The summary of 20000 words is a nightmare for four people, and it will be handed in tomorrow. If human beings can't do such a thing, it's just that Mr. Xu is not human...

"in the micro world, we usually use wave function to describe the motion state, and the state will follow a certain return law with the change of time." Xu said solemnly: "the state of a particle at a certain moment is known. We need to use the Schrodinger wave equation to determine the future state of the particle."

"At this point... You've done a good job." "I live up to what I learned in theoretical physics in the Department of physics," Xu said

"But..."

"this computational and thinking ability needs to be imposed, and the concept of wave function also needs to be strengthened." Xu said solemnly, "generally speaking, I am very dissatisfied with your performance."

Two high-quality students from the Department of physics were criticized by Xu Mang, but they did not dare to talk back. The other side was crushing himself in terms of identity and strength.

"And you

"The so-called top students in the materials department." Xu Mangchong, two students in the Department of materials, said, "don't you think there is a problem with the bond between atoms and molecules?"

"Lin wanwan!"

"Tell me what covalent bonds and metal bonds are!" Xu asked, "this is the content in the foundation of materials science. Let me know now."

Maybe she was frightened by the serious Xu mang. Lin wanwan forgot everything for a while. The combination key should be a very basic thing, but now she has forgotten what is the combination key.

Facing the silent Lin wanwan, Xu mang turned to look at Liu Zhuo and asked, "the three sources of van der Waals force, tell me which three are!"

"Er..."

"electrostatic force, inducing force... And... And..." Liu Zhuo also forgot the most basic things he had learned because of his nervousness.

Xu mang is so angry. What's the situation?

Not all knowledge?

It should not be,

Xu mang thinks that these people are not less capable than ordinary students. Otherwise, they would not be recommended to do research here. After all, this is a cooperative project with Qingda, and there is only one reason to explain the current situation.

These people's psychological quality is too poor. If they scold them casually, they forget what they have learned. This kind of pressure resistance ability is not suitable for research.

At this time,

when they saw Xu Mang's silent face, they all lowered their heads in shame.

Shame!

What a shame!

The chain fell off at the critical moment.

Then,

in silence, Xu mangmo began to use the equations of quantum mechanics to obtain the motion and distribution of an electron. The whole laboratory was silent in a depressed environment.

Soon,

Xu Mang's calculation is coming to the final stage.

"The energy of particles in this well is quantized, so we can only take one set of values." "The quantization of energy is the natural result of the wave particle duality of matter," Xu mang said expressionless

"This is an expression of particle density."

"This is the expression of a particle in the state of quantum number n."

In a word,

Xu pointed to his two-dimensional image and said seriously: "this image represents the energy level, wave function and probability density distribution curve. From the above, we can know that for different quantum numbers, the probability of particles appearing at a certain point is different."

For a particle in a certain region, it can only move in a certain region Xu mang looked at the four and asked curiously, "do you understand?"

"..."

"..."

"

"... "

what a profound content!

This is much deeper than the professor taught.

"Do you understand?" Xu asked.

Lin wanwan pointed to a formula and said to Xu: "starting from here, I'm a little confused. I'm basically listening to the book of heaven."

"You don't need to understand the physical concepts behind it." Xu Mangchong, two top students in physics department, asked, "what about you two?"

"..."

"..."

Zhang Xu and Li Wentao nodded and said in silence: "basically understand."

"Oh..."

"go back." Xu mang stretched out a stretch, and suddenly said with a smile: "don't forget to hand in a report of 20000 words tomorrow. It will be better if you can write it in a more profound way."

As a result,

Xu mang left the laboratory.

Looking at the back of leaving, the four can't accept such a defeat for a while. They belong to Xueba and are determined to win Xu Mang's approval.

"Alas..."

"this is the so-called gap." Zhang Xu reluctantly said: "I was in the top of the school since I was a child. As a result, I met a real top-level talent. My strength is ridiculous... This time is too tragic."Zhang Xu's words were also the voice of the other three people, but soon several people were relieved that they were not on the same scale, so they could not compare with each other because he was not a human being.

Picture and text?

What to do?

Write a summary and learn to draw...

...

at this time,

at this time,

Xu mang found director Fang. He needed a high-quality student majoring in chemistry, preferably one who knew physics. However, director Fang asked Xu mang to find out by himself.

Soon,

Xu mang came to the building of the Department of chemistry.

"Classmate."

"Can you tell me how to get to the building of the Department of chemistry?" Xu asked.

"The third floor."

"Oh..."

Xu mang was about to leave when the girl stopped Xu Mang and asked curiously, "are you... Xu mang?"

"Yes."

"What's the matter?" Xu mang stopped and asked with a confused face.

"Ah?"

"No... nothing." "I'm a graduate student majoring in physical chemistry in the Department of chemistry. My main direction is to study physics in the field of chemistry. I'll... Goodbye."

The girl left in silence.

Xu Mang: ∑ (°Δ°||︴︴︴︴︴︴︴︴︴︴︴︴︴︴︴︴︴!

"This classmate, wait a minute!" Xu mang quickly stopped the girl who had just left: "there is a research opportunity here. Did you lose it?"

"Yes The girl said happily.

Soon,

the two came to the coffee shop, and Xu mang wanted to make a necessary assessment on the girl.

"My name is Zhou Mengdi." Zhou Mengdi, a graduate student in the Department of chemistry, said, "I heard that there is a scientific research project cooperating with Qingda, so... I planned to try it tomorrow, but I just met you today."

"Oh..."

Xu mang thought for a moment and asked curiously, "how is your physics?"

"Very good."

"My direction focuses on Mathematics and physics. I use theoretical physics to study chemical reactions and material structures. Sometimes, I use theoretical physics to build models, describe them quantitatively with mathematics, and then write programs for computer simulation." Zhou Mengdi said: "in fact, it is theoretical chemistry."

Sleeping trough!

Isn't this just what I did?

Xu mang basically has the invincible conditions in theoretical chemistry. Physics and mathematics are basically his strengths, and theoretical chemistry just needs to use these two skills.

"Can you give me a brief description of what you did?" Xu asked.

"Er..."

"for example, classical mechanics or quantum mechanics are used to simulate the motion of atomic nuclei, to study the microscopic nature of chemical reactions, and to construct the potential energy surfaces of molecules and their interactions by using classical mechanics or quantum mechanics." "It's usually done on a computer," Zhou said

Yes!

It's a talent!

Xu mang was very interested in theoretical chemistry and immediately said, "come to my laboratory to do research tomorrow. You are responsible for it. Let's talk about it then."

Thank you

"I will try my best!" Zhou Mengdi said seriously.

Looking at Zhou Mengdi's departure, Xu mang shows a smile. He plans to learn theoretical chemistry secretly when he has time. Although he has all the invincible conditions in this field, he does not know the specific process of theoretical chemistry. Now Zhou Mengdi is here, and almost all the problems have been solved.

Then, Xu mang came to the director's office of the Department of chemistry. After hearing the call to come in, Xu opened the door.

"Are you?" An old man with white hair asked curiously.

"Hello, director."

"I'm Xu Mang of the physics department." Xu mang said with a smile.

"Xu mang?"

"What brings you here?" Knowing Xu Mang, the old man with white hair asked curiously, "are you planning to enter chemistry?"

"..."

"no, no, no!" Xu mang shook his head in a hurry and said seriously, "I don't have this plan for the time being. In fact, the director... I'm here to borrow a student from you."

"Borrowed?"

"To your project team?" The old man with white hair said, "I remember that there was a project cooperated with Qingda recently. Are you the person in charge of Fuda? Is it related to this project? "

Xu mang nodded: "yes, I want to borrow Zhou Mengdi."

"..."

"your boy's eyes are very poisonous!" The old man with white hair said with a smile: "I borrowed the top students of our department as soon as I opened my mouth. Have you done research before?"

"Just met at the door, and then talked for a while, feeling a bit fierce." Xu mang said with a smile: "director... I borrowed it?""All right."

"Since I participated in the cooperation project with Qingda, I should lend it to you." The old man with white hair said, "Xu Mang, you owe a favor."

With a smile on his face, Xu mang said, "how about if I buy you a big fruit basket, director?"

Fruit basket?

Is it Xue dingxu's fruit basket?

The old man with white hair pondered for a moment, and immediately refused Xu Mang's offer, because it was very likely that he would not be able to eat the fruit basket.

The next day, Xu mang came to the laboratory early and found that Lin wanwan and his four people were doing research, and there were four more summary reports on his desk.

After reading it for a while,

Xu mang signed his name on the last page and put it in the drawer to wait for Zhou Mengdi's arrival.

Soon,

Zhou Mengdi came to the laboratory.

"Cough!"

"To introduce you, this is a new member of the team, Zhou Mengdi from the Department of chemistry." "It mainly helps you with your research," Xu said

After a glance at Lin wanwan, Xu mang said, "Lin wanwan, tell Zhou Mengdi about our research."

Soon, the five became familiar with each other. It may be that Zhou Mengdi's theoretical chemistry is just related to materials and physics, and they are mutually related, cooperating and promoting each other.

So far,

Lin wanwan and Liu Zhuo are responsible for the macro problems of materials, Zhang Xu and Li Wentao are responsible for the micro problems of materials, while Zhou Mengdi clarifies the relationship between macro and micro.

Looking at the thriving picture, Xu mang is more gratified, and finally he can't carry the salted fish.

Xu Mang: zzz

at this time,

Zhou Mengdi found Xu mang sleeping and asked with a confused face, "Wan Wan Wan, what's the situation

According to Zhou Mengdi's direction, Lin wanwan saw Xu mang lying on the table sleeping and said helplessly, "don't be surprised, you will get used to it later."

"Habit?"

"As the responsible person of the cooperation project, Mr. Xu is not responsible?" Zhou Mengdi frowned and seriously said, "you just watch, master Xu degenerate?"

"What can I do?" Lin Wan Wan said bitterly, "we just had him educated yesterday."

"Mengdi..."

"never mind the affairs of tutor Xu." Lin wanwan said: "otherwise, he will give him a miserable education, a summary of 20000 words, and pictures and texts... You will collapse."

However,

Zhou Mengdi is a person who does not believe in evil.
