The 20,000-word summary is simply a nightmare existence for the four of them, and they have to be handed in tomorrow, no human being can do such a thing, and it is not a human being like Mentor Xu...

"In the microcosm, we generally use the wave function to describe the state of motion, and the state will follow a certain law of return with time. Xu Mang said solemnly: "The state of the particle at a certain moment is known, and the state of the particle in the future needs to be determined by the Schrödinger wave equation." ”

"At this point... You're doing a great job. Xu Mang said: "I have lived up to the knowledge I learned in the theoretical physics major of the Department of Physics. ”

"But..."

"This ability to calculate and think needs to be imposed, as well as the concept of the wave function. Xu Mang said solemnly: "In general... I'm very dissatisfied with your performance!"

The two high-achieving students from the Department of Physics were criticized by Xu Mang, but they didn't dare to talk back, the other party crushed him in terms of identity and strength.

"And you!"

"The so-called high-achieving students of the Department of Materials. Xu Manchong said to the two students of the Department of Materials: "Don't you think there is a problem with the bonding bond between atoms and molecules?"

"Lin Wanwan!"

"Tell me what covalent bonds and metal bonds are!" Xu Mang asked, "This is the content of "Fundamentals of Materials Science", tell me right away." ”

may have been frightened by the serious Xu Mang, Lin Wanwan forgot all about it for a while, the binding key should be a very basic thing, but now she has forgotten what the binding key is.

Facing Lin Wanwan, who was silent, Xu Mang turned his head to look at Liu Zhuo and asked, "The three sources of Van der Waalsli, tell me which three!"

"Uh..."

"Electrostatic force, inductive force... And... And..."Liu Zhuo also forgot the most basic things he had learned because of nervousness.

Xu Mang is so angry, what's going on?

Not fully learned?

Probably not,

Xu Mang thinks that these people's abilities are much better than ordinary students, otherwise they would not be recommended to come here to do research, after all, this is a project in cooperation with Qing University, and there is only one reason that can explain the current situation.

The psychological quality of these people is so poor that they are casually scolded by themselves, and they forget what they have learned, so they are not suitable for research because of their ability to resist pressure.

At this point,

When the four of them saw Xu Mang's silent face, they all lowered their heads in shame.

Lose face!

What a shame!

At the critical moment, the chain actually dropped.

Followed by

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

soon

Xu Mang's calculations are about to reach their final stage.

"The energy of the particles in this potential well is quantized, and we can only take a set of values. Xu Mang said expressionlessly: "The quantization of energy is the natural result of the duality of matter and waves. ”

"This is an expression of the density of particles. ”

This is the expression that the particle is in a state where the quantum number is n. ”

Words fall,

Xu Mang pointed to his two-dimensional image and said solemnly: "This image represents the energy level, wave function and probability density distribution curve, from which we can know that for different quantum numbers, at a certain characteristic point, the probability of particle appearance is also different. ”

"For infinitely deep potential wells, particles can only move in a specific area. Xu Mang glanced at the four of them and asked curiously, "Do you understand?"

“...”

“...”

“...”

What a deep content!

This is much deeper than what the professor taught.

"Do you understand?" asked Xu Mang.

Lin Wanwan pointed to a certain equation and said to Xu Mang: "From here, I am a little confused, and then I basically listen to the book of heaven." ”

"You don't need to understand the physics concepts behind it. Xu Mang asked the two top students of the physics department, "What about the two of you?"

“...”

“...”

Zhang Xu and Li Wentao nodded and said silently: "I basically understand." ”

"Oh..."

"Let's go back. Xu Mang stretched his waist, and suddenly said with a smile: "Don't forget to hand in a 20,000-word report tomorrow, write a little more profoundly, it would be best if it could be illustrated and written." ”

Words fall,

Xu Mang left the laboratory.

Looking at the back of the leaving, the four of them couldn't accept such a defeat for a while, and a few people who belonged to the top students themselves were determined to get Xu Mang's approval.

"Ugh..."

"It's called a gap. Zhang Xu said helplessly: "Since I was a child, I have been among the top few in the school, but when I met a real top-level genius, my strength is simply ridiculous... This time it was too miserable. ”

Zhang Xu's words were also the voices of the other three, but soon several people were relieved again, and they were not on the same order of magnitude at all, so they couldn't compare, because he was not human.

Illustrated?

What to do?

Write a summary and learn to draw...

...

At this point,

Xu Mang found Director Fang, he needed a top student majoring in chemistry, preferably a chemistry student who knew physics, but Director Fang asked Xu Mang to find it himself.

soon

Xu Mang came to the building of the Department of Chemistry.

"Classmates. ”

"How do you get to the chemistry building?" asked Xu Mang.

"Third floor. ”

"Oh..."

Xu Mang was about to leave, but the girl suddenly stopped Xu Mang and asked curiously, "Are you... Xu Mang?"

"That's right. ”

"Is there something wrong?" Xu Mang asked with a confused expression.

"Huh?"

"No... Nothing. The girl said: "I am a graduate student majoring in physical chemistry in the Department of Chemistry, and my main direction is to study physics problems in the field of chemistry. Good bye. ”

Words fall,

The girl left silently.

Xu Mang: Σ(°△°|||) ︴

That's her!

"Wait a minute, this classmate!" Xu Mang hurriedly called out to 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 café, and Xu Mang wanted to conduct the necessary assessment of this girl.

"My name is Zhou Mengdi. The girl named Zhou Mengdi said: "I am a graduate student in the Department of Chemistry, I heard that there is a scientific research project in cooperation with Tsinghua University, so... I was going to try it tomorrow, but I happened to run into you today. ”

"Oh..."

Xu Mang thought for a moment and asked curiously, "How are you doing physics?"

"Very nice. ”

"My direction is biased towards mathematics and physics, using theoretical physics to study chemical reactions and the structure of matter, sometimes using theoretical physics to build models, using mathematics to quantitatively describe them, and then writing programs to study problems in computer simulation. Zhou Mengdi said: "In fact, it is theoretical chemistry. ”

it!

Isn't that exactly what I'm doing?

Xu Mang basically already has the conditions to be invincible in theoretical chemistry, physics and mathematics are basically his strengths, and theoretical chemistry needs these two skills.

"Can you briefly describe what you did?" asked Xu Mang.

"Uh..."

"For example, classical mechanics or quantum mechanics is used to simulate the motion of atomic nuclei, the microscopic nature of chemical reactions is studied, and classical mechanics or quantum mechanics is used to construct the potential energy surface of molecules and intermolecular interactions. Zhou Mengdi said: "It is usually done on the computer. ”

OK!

It's a talent!

Xu Mang was very interested in theoretical chemistry, and immediately said: "Come to my laboratory tomorrow to do research, you are in charge... We'll talk about that then. ”

"Thank you!"

"I'll work hard!" Zhou Mengdi said seriously.

Looking at the back of Zhou Mengdi's departure, Xu Mang showed a smile, he planned to have time to learn theoretical chemistry secretly, although he had all the conditions for being invincible in this field, he didn't know the specific process of theoretical chemistry, and now Zhou Mengdi was there, and almost all the problems were solved.

Followed by

Xu Mang came to the office of the head of the chemistry department, and after hearing the shouts from inside, Xu Mang pushed the door and entered.

"Are you?" asked a white-haired old man curiously.

"Hello Director. ”

"I'm Xu Mang from the Department of Physics. Xu Mang said with a smile.

"Xu Mang?"

"What kind of wind has blown you here?" The white-haired old man knew Xu Mang, and couldn't help but ask curiously, "Are you planning to enter chemistry?"

“...”

"No, no, no!" Xu Mang hurriedly shook his head and said seriously: "I don't have this plan for the time being, in fact, the director... I came to you to borrow a student from you. ”

"Borrow?"

"To your project team?" the white-haired old man said, "I remember that there was a project with Qingda recently, and you are the person in charge of Fuda, right?

Xu Mang nodded: "That's right, I want to borrow Zhou Mengdi." ”

“...”

"Your kid's eyes are very vicious!" the white-haired old man smiled: "As soon as you opened your mouth, you borrowed the top students of our department, did you do research before?"

"I just met at the door, and then we talked for a while, and it felt a little powerful. Xu Mang said with a smile: "Director... Did I borrow it?"

"Okay!"

"Since I am participating in a cooperation project with Qingda, I should lend it to you. The white-haired old man said, "Xu Mang, you owe a favor." ”

Xu Mang smiled and said, "Or... Director, how about I buy you a big fruit basket for you?"

Fruit basket?

Could it be Schrödingh's fruit basket?

The white-haired old man thought for a while, and immediately rejected Xu Mang's kindness, because it was very likely that he would not be able to eat the fruit basket he sent.

Following

Xu Mang came to the laboratory early, and when he opened the door, he found that Lin Wanwan and the four of them were engaged in research, and there were four more summary reports on his desk.

After looking at it for a while,

Xu Mang signed his name on the last page, and then put it in a drawer, waiting for Zhou Mengdi's arrival.

soon

Zhou Mengdi came to the laboratory.

"Ahem!"

"Let me introduce to you, this is a new group member, Zhou Mengdi from the Department of Chemistry. Xu Mang said, "Mainly to assist you in your research. ”

Words fall,

Glancing at Lin Wanwan, Xu Mang said, "Lin Wanwan, you and Zhou Mengdi tell us about our research. ”

Soon the five of them became acquainted, and it may be that Zhou Mengdi's theoretical chemistry happened to be interrelated, coordinated, and promoted with materials and physics.

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, and Zhou Mengdi is responsible for the relationship between macro and micro.

Looking at the thriving picture, Xu Mang felt very relieved, and in the end, he couldn't bear the salted fish.

Xu Mang: Zzzz

At this point,

Zhou Mengdi found that Xu Mang was sleeping, and asked with a confused face: "Wanwan, this... What's going on?"

Following the direction pointed by Zhou Mengdi, Lin Wanwan saw Xu Mang sleeping on the table, and couldn't help but say helplessly: "Don't be surprised, you will get used to it in the future." ”

"Habit?"

"Is Tutor Xu, as the person in charge of the cooperation project, so irresponsible?" Zhou Mengdi frowned and said with a serious face: "You just watched Tutor Xu fall?"

"What should I do? Lin Wanwan said with a bitter face: "We just educated him yesterday. ”

"Mondi..."

"Don't worry about Mentor Xu. Lin Wanwan said: "Otherwise, he will be given a miserable education, a 20,000-word summary, and it will be full of pictures and texts... You're going to crash. ”

But

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