Except for one doctor, two masters stayed, and the other four went back first.

To be honest, the quality of the students enrolled this time is very average, at least in Lu Zhou's opinion.

But this can't be blamed on others, after all, he was busy with controlled fusion engineering all year last year, and he didn't have time to take care of the school's side, and he didn't update his information on the admissions website until the end of the year.

Normally, the quality of the students is basically divided every summer.

Among the students in the master's group, except for Han Mengqi, who is engaged in computational materials, and another mathematician named Feng Jin, most of the others have no scientific research experience.

For example, Liu Siyuan, who is standing here, is another master in the direction of computational materials. Although the grade point of the four-year undergraduate is quite good, and the undergraduate degree is also very valuable, the scientific research experience is almost zero.

But even so, it doesn't matter, after all, most undergraduates in the undergraduate stage, except for experimental courses and course design, if they are not particularly close to the teacher or lucky enough to catch up with the talent training plan of the school, they will not have the opportunity to participate in scientific research projects.

"You used to be Aurora?"

Wu Shuimu: "Yes. ”

Lu Zhou: "Who is your mentor?" ”

Wu Shuimu: "Professor Liu Xianglong, the direction of functional analysis I read with him. ”

Lu Zhou thought for a while, but he didn't have any impression of the name, so he changed the topic and continued to ask.

"Have you ever been exposed to materials science before?"

Wu Shuimu scratched the back of his head embarrassedly, "I have been in contact with a little, our professors from the Institute of Chemistry have done a project on the mechanical dispersion of single-walled carbon nanotubes in a medium, and I helped them model and analyze the collected data. ”

Raising his eyebrows with interest, Lu Zhou asked with a smile, "This is the opportunity for you to choose computational materials?" ”

"Sort of," Wu Shuimu said with a smile, "I feel that I have touched my ceiling in functional analysis, and no matter how much I research, it is difficult to innovate on the original theory, so my teacher suggested that I switch from pure theory to application." It was during that time that I saw your acceptance speech when you received the Cafford Prize, and I was deeply touched by the words that mathematics changes science, and from then on I made up my mind to do computational materials! ”

At the end of the day, there was almost a sense of mission in his voice.

Liu Siyuan looked at this senior brother with admiration, and secretly said in his heart, "Ah, this licking skill is simply invincible."

Han Mengqi twitched her eyebrows, and she couldn't bear to look away.

Hearing this, Lu Zhou smiled embarrassedly.

Is this considered sycophancy?

Anyway, he's pretty comfortable to listen to anyway.

Clearing his throat, Lu Zhou spoke.

"Now that you have your goals, work hard towards them. In addition, according to what you said, you should be a bit basic in calculating materials, so I will assign you some relatively comprehensive tasks. ”

After that, he looked at Lin Yuxiang, who was closest to his desk.

"Come over for my marker."

"I'm looking for ......"

Lin Yuxiang rummaged through the drawers, quickly found a black marker, and handed it over with a smile.

"Give~"

"Thank you."

Habitually saying thank you, Lu Zhou took the marker from her hand, walked to the whiteboard on the edge of the office, stared at an empty whiteboard and muttered for a while, and then picked up the pen and wrote on it.

【Ψ（r1，r2，……，rn）=∏Ψt（rt）】

【{pi²/2m+V（ri）+1/4πε0∑∫drf|Ψj（rj）|²e²/|ri-rj|} Ψi（ri）=EiΨi（ri）】

【……】

Looking at the lines of calculations on the whiteboard, Wu Shuimu's expression was slightly moved: "This is ......"

"The theoretical model of the electrochemical structure interface," finally wrote the last line of calculations, stopped the marker in his hand, Lu Zhou smiled and said, "You should have understood." ”

Wu Shuimu coughed dryly and said, "Professor, you are laughing...... Now do computational chemistry in this direction, who doesn't know your theoretical model of the electrochemical structure interface. ”

A first-principles calculation, a theoretical model of the electrochemical structural interface, these two plates are now almost two mountains of computational materials science.

When he was studying at Aurora, his mentor, Professor Liu Xianglong, highly praised this theoretical model, saying that it brought the method of functional analysis to the extreme.

Although at his current level, he still can't understand what the "extreme" is that makes his mentor amazed, but when he watched Lu Zhou write out these steps on the spot, his heart was still quite shocked.

He asked himself, even if it was a paper written by himself, it was impossible to say that it was written word for word, and at most it was just a final conclusion.

He believed that it was impossible for Lu Zhou to remember the papers he had written word for word.

Thinking about it this way, it is very likely that these things were deduced by him on the spot......

looked at the communication between the senior brother and the professor with a confused face, and the two master's students couldn't say a word.

Even Han Mengqi, who has been a part-time intern at the Institute of Computational Materials for two or three years, didn't understand what they were discussing. Although he has participated in several research projects, it is clear that the people in the institute do not throw too much work to an undergraduate student.

Something as advanced as "a theoretical model of the electrochemical structural interface" is still too advanced for her to get started.

Lu Zhou: "In fact, this model is not absolutely perfect, or there is room for improvement and further generalization to other fields. For example, with the many-body wave function as the basic variable, we can evolve new configuration correlations, many-body perturbation theory and coupling cluster methods at different levels, and the accuracy of their calculation and prediction can also be systematically improved. ”

"What I need you to do now is to make further generalizations on this theoretical model of the electrochemical structural interface. While the work is probably similar to retouching a window on a completed building, it's just as important. After all, with your current ability, it is not enough to add a floor to this building. ”

Wu Shuimu nodded seriously and said, "I know, I will do what you say." ”

Lu Zhou nodded with satisfaction.

Not bad, yes, the children can be taught.

"Come on, if you really go deep into this field, maybe you can do two JACS works before you graduate with a Ph.D."

Two top publications and one work!

This is enough to rely on the threshold of Qingqian!

Hearing this, Wu Shuimu suddenly said happily: "Hmm! I'll try! ”

Lu Zhou nodded with a smile and continued to look at the two masters.

"Your task is to understand what I'm writing on this whiteboard first."

"When you understand these basic things, I will assign you specific scientific research tasks. If you encounter something you don't understand in the process of studying, you can ask your senior brother Dr. Wu Shuimu, and if he can't explain clearly, you can ask me again. ”

Where is this thing based......

Although Liu Siyuan and Han Mengqi both wanted to complain like this, they still nodded stubbornly.

Especially Liu Siyuan.

He can only be regarded as an ordinary study in the undergraduate level, although the grade point is already very good, but there are no additional points in the academic field.

Although he had a certain amount of psychological preparation before this, he still didn't expect that he would have a feeling of difficulty at the beginning.

Sure enough, it is not easy to go to graduate school under the Nobel Prize bigwig.

If you don't have a talent that is far beyond ordinary people, if you want to keep up with his rhythm, you can only rely on bursting your liver......

……

After explaining their respective tasks, Lu Zhou threw down the marker pen in his hand and announced the disbandment, so that they could go back first.

Before leaving, Han Mengqi deliberately slowed down and stayed at the end.

After the others left, she looked at the door, then at Lu Zhou, and whispered.

“…… Master. ”

Looking at the little girl's nervous face, Lu Zhou couldn't help but be a little amused, and said, "What's wrong?" ”

The overlapping index fingers and thumbs were entangled with each other, and Han Mengqi, who lowered his head, whispered, "That...... I did it. ”

Originally, she had a lot to say, but she didn't know why, and at this moment, she didn't know how to speak.

Lu Zhou: "Well, congratulations! ”

Staring at the gap between the tiles on the floor, Han Mengqi pursed her mouth lightly with some unhappiness.

"Don't you have anything else to say?"

Lu Zhou thought for a while and said, "To be honest, I'm quite surprised. ”

Han Mengqi: "...... Astonished? ”

Lu Zhou smiled and said, "Well, do you remember what I said to you at the beginning?" If you can be admitted to Kim University, I will agree to you being my apprentice...... I didn't expect you to actually do it. ”

Hearing that Lu Zhou actually underestimated himself, Han Mengqi said a little unhappily: "What, I'm a student you taught, can't I even do this little thing?" ”

"Don't be like this, it's still a bit difficult to get into Jinda," Lu Zhou coughed lightly and continued, "Of course, what really surprised me was not that you were admitted to Jinda four years ago, but that you are still standing here four years later. ”

Han Mengqi looked at him with some confusion, not understanding what he was talking about.

After a pause, Lu Zhou continued.

"I've always believed that time can change a person. In other words, not just people, it can change anything, including the particles that make up the most fundamental part of this universe. ”

"All the problems that cannot be solved for the time being can theoretically be solved by time...... And you, let me see another possibility. ”

Han Mengqi tilted her head: "Another possibility? ”

Lu Zhou nodded: "Well, even time, there are things that it can't change." Just like you told me at the time, you like math the most, but I didn't take it to heart at the time, just a child's joke. However, after four years, I didn't expect you to persist as always, and with your own efforts, you were admitted to my master's degree...... To be honest, I was surprised. ”

When he said this, Lu Zhou's mood was actually full of complexity.

If there really were something that time could not change......

From the outset, then, the idea of leaving that matter to time to solve was a mistake in itself.

"Actually, it's not just math...... didn't realize Lu Zhou's mood, Han Mengqi scratched her cheeks a little embarrassed, stared straight at the toes of her shoes, and gently rubbed the edge of the tile gap, "Chemistry or something, I'm also quite interested." ”

Coming back to his senses, Lu Zhou covered up the unnaturalness of his expression with a smile.

"Well, it's a lot of fun to study science, and I hope you enjoy it as always."

"I will!" Looking up at Lu Zhou, Han Mengqi nodded firmly, but after a while, her raised gaze drifted to the floor again, "That, there's one thing, in fact, I've always wanted to tell you......"

Lu Zhou: "What's the matter?" ”

Han Mengqi: "In August last year, my mother and father divorced......"

Looking at the concerned expression on Lu Zhou's face, the corners of Han Mengqi's mouth curved.

Although she didn't really want to talk about this sad topic, she continued.

"If it had been before, I would have cried a lot, and I would have been unable to get out of that room, and I would have missed a lot of interesting things......

As she spoke, a cheerful smile bloomed on her face.

"Although it may have been four years late...... But I still ......"

“…… I still want to say thank you to you! ”

Thank you for saving me......

After saying this sentence silently in her heart, Han Mengqi turned around and ran out of the door.

Looking at the back that slipped away from the office, Lu Zhou was slightly stunned, then shook his head with a smile, and his originally slightly boring mood was also diluted a lot.

I didn't expect to be such a joyful thing to help others.

To be honest, he didn't think about it at all when he was doing that part-time job......
