Qin Ke looked at the door of the classroom, only to see a young man in his twenties and seventies looking at him with a smile.

This young man is wearing a casual suit, formal but not serious, and has short hair, looking very capable.

Qin Ke said unexpectedly: "Professor Chen, are you looking for me?"

He did know Chen Licheng. The first time they met was in an online academic live broadcast room when he was a sophomore in high school. Chen Licheng, who was still studying for a Ph.D. at MIT at the time, met with him and kindly invited Qin Ke to join his scientific research team. The second was two weeks later.

Many years ago, Vice President Gu asked him to go to the roundtable conference room for a meeting. Chen Licheng was also among the professors attending the meeting. The two had a brief chat. Only then did Qin Ke know that Chen Licheng had returned to China and was studying mathematics at Qingmu University.

I'm an associate professor in the Department of Science, but classes haven't started yet.

Chen Licheng walked in and said with a smile: "You don't have to call me Professor Chen. As I said last time, just call me senior. I won't disturb your class, right?"

Chen Licheng released his intimacy and kindness, and Qin Ke would not refuse. He also had a good impression of this cheerful and capable senior: "It's just a break between classes. What's the matter with Senior Chen looking for me? How about we go out and chat?"

"Okay, I'll just interrupt you for a few minutes." Chen Licheng smiled and said to Ning Qingyun, who was standing next to him: "Xiao Ning, do you mind if I lend you your boyfriend for a few minutes? Don't worry, I'm not introducing another girl to you.

He knows him."

These words made Ning Qingyun blush. She was not good at talking to strange boys, let alone joking with them. And Chen Licheng was a professor-level teacher, so she couldn't roll her eyes at him, so she had to

He looked at Qin Ke as if asking for help.

Qin Ke said with a smile: "Senior Chen is really impeccable in his work. He has even considered this slim possibility. He is worthy of being a top talent specially brought back by the country. Such a scientific research attitude is worthy of serious study by us juniors."

Chen Licheng laughed and patted Qin Ke on the shoulder: "You kid, no wonder some people say that even if you don't engage in scientific research, you will have a smooth path to politics."

The two of them were talking and walking, which attracted a lot of curious eyes.

Arriving at a secluded spot in the corridor, Chen Licheng got straight to the point: "Junior Qin Ke, this time as a senior I have encountered a problem in a scientific research project, and I would like to ask for your help."

Qin Ke asked strangely: "Senior Chen, you can't solve it even with your abilities?"

Chen Licheng shook his head bitterly: "If we hadn't encountered a difficult hurdle that almost stalled the project, I wouldn't be shameless enough to trouble you. I know you still have the subject of Polignac's conjecture to do.

, I usually have a lot of courses...Of course, I won’t ask you to join my team, just as a foreign aid, you can provide some help or ideas.”

Qin Ke saw the worry on Chen Licheng's eyebrows and knew that he was telling the truth, so he became curious.

For someone who loves mathematics like him, he can't help but be eager to try if he finds a difficult problem that can actually defeat a very high-level associate professor.

"My level is not as good as the senior's. If the senior needs my help and advice, I can try my best."

Chen Licheng was overjoyed and said in a low voice: "Whether it succeeds or not, this time I, as a senior, owe you a favor. Alas, as you know, this is the first scientific research project I have taken on, and it is not good either."

Ask other professors for advice...otherwise you will make people laugh."

Qin Ke immediately understood that Chen Licheng came back with a halo, which would naturally attract the attention of many professors. It would be really embarrassing if he asked his colleagues for help on his first project.

But Qin Ke is different. Chen Licheng had called him "Junior Qin" in front of others before. That is the relationship between senior and junior. It is normal for seniors to exchange academic issues with juniors. Who can chew their tongue?

Chen Licheng's trust and intimacy made Qin Ke feel very comfortable. Perhaps this is also the charm of Chen Licheng. He is a bit proud but has an open mind.

"No problem, Mr. Chen, please tell me when is the appropriate time to go to your laboratory?"

When Chen Licheng saw Qin Ke being so cheerful, his feelings for him increased greatly. This junior Qin was more popular in the school than many professors, and he indeed had a very likable personality.

"If it's convenient, I'll treat you and Xiaoning to dinner at noon, and then go to my research laboratory together?"

"I'll treat you to lunch, and I'll make up for the feast for Senior Chen at that time."

"Hey, no, no, no, no, it's me, the senior, who should welcome you and Xiaoning to Qingmu University. That's it."

…

After lunch, Qin Ke asked Ning Qingyun to go back to the study room to study first, while he followed Chen Licheng to the research room.

Although Chen Licheng also invited Ning Qingyun, Qin Ke knew that this scientific research project was too important to Chen Licheng and it was not appropriate for Ning Qingyun to follow him.

Chen Licheng saw it and appreciated it even more.

This kid is really good at doing things, but it's a pity that he can't bring him into his research team, otherwise he will definitely become his most trusted general.

——Chen Licheng is still self-aware. Although his Schrödinger equation is also very important and difficult, it is still far behind the world-famous problem of Polignac conjecture. Qin Ke is already working on it with Ning Qingyun.

With the conjecture of conquering Polignac, how could he join his team?

"Speaking of which field does Mr. Chen specialize in at MIT?"

"My main field of study is mathematical physics, and my second field is functional analysis."

The so-called mathematical physics is a mathematical theory and mathematical method aimed at studying physical problems. It is an important branch of mathematics. It uses mathematical language to describe physical phenomena by establishing mathematical models. Simply put, it uses mathematical methods to

Interpret and predict physical phenomena.

Functional analysis is also an important branch of mathematics. It can be regarded as the analytic geometry and mathematical analysis of infinite-dimensional vector spaces. It is widely used in mathematical physics equations, probability theory, and computational mathematics.

Mathematical physics and functional analysis are indeed the golden combination.

Qin Ke smiled and said: "Then I guess, Mr. Chen, the topics you study are mostly in the direction of mathematical physics."

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "You guessed it, my topic is to study the Schrödinger equation. Do you know the Schrödinger equation? It is the most important equation in quantum mechanics."

Qin Ke has mastered the theoretical knowledge from the undergraduate physics department, so how could he not know the Schrödinger equation? It is a non-relativistic wave equation that reflects the laws that describe the state of microscopic particles changing with time.

The status of Schrödinger's equation in quantum mechanics is equivalent to that of Newton's law in classical mechanics, and it is one of the basic assumptions of quantum mechanics.

However, Qin Ke still modestly said that he had only heard the general outline and did not know much about the details.

Chen Licheng is not surprised. To be honest, Qin Ke has achieved relatively few achievements in physics, just a perfect score champion in IPhO. That is only in the category of high school physics. Compared with the scientific research achievements in mathematics and even computers, it is simply

Can be ignored.

Chen Licheng patiently explained the Schrödinger equation to Qin Ke, and then said: "Currently, our team is encountering difficulties in studying the regular solution of the steady-state form of the Schrödinger equation—that is, the solution under mass constraints.

The 'steady state form' mentioned here refers to the situation of two material states. Because there are two mass constraints, it becomes more difficult and complicated to prove the existence of the solution."

While talking, the two of them had arrived at Chen Licheng's research room.

Chen Licheng's laboratory is located to the southeast of the scientific research center. The mathematics laboratory is the easiest. It only needs tables, chairs, blackboards, whiteboards, and manuscripts. It doesn't even require experimental equipment, so his laboratory is obviously relatively spacious and even has a bathroom.

There is also an independent lunch room, which is convenient for the research team to take a lunch break - of course, it is even more convenient to sleep here directly after staying up all night.

The five doctoral students in Chen Licheng's team were still arguing there, and the quarrels could be heard in the distance.

Chen Licheng said with some helplessness: "We have been stuck here for almost a month. Everyone is a little angry. Don't be offended if someone speaks more irritably later. People who do mathematics have somewhat awkward personalities. Oh, of course.

Brother Qin, you are an exception. You have a cheerful personality and are not prone to depression. Ha, mathematicians are said to be more prone to depression than writers."

Qin Ke smiled and nodded, and the two of them pushed the door open and walked in. They saw a few doctoral students dressed casually, without even combing their hair, and with tired faces, pointing at the mathematical formulas on the whiteboard and arguing.

Seeing that Chen Licheng was here, the doctoral students stopped arguing and greeted each other: "Professor Chen."

It can be seen that Chen Licheng's prestige in the team is still very high.

The eyes of several doctoral students soon fell on Qin Ke. They were surprised, curious, and confused.

Chen Licheng said: "This is junior Qin Ke. I believe everyone has heard of his name, right?"

A doctoral student with narrow eyes was the first to react and said enthusiastically: "It turns out to be junior Qin Ke. I have heard of your name a long time ago. I heard that you solved the twin prime conjecture? Is this true?"

Qin Ke said with a smile: "I can't say whether there is such a thing. I don't understand it even if I say it. It needs to be recognized by the international mathematics community."

"So the rumors are true? It's true that the Yangtze River is pushing the waves ahead. I admire you. My surname is Hua, and my name is Hua Hong. I am the Hong of the torrent, not the one who was cut off by Guan Yu Wenjiu."

The other doctoral students were silent or introduced themselves. After a brief greeting, Qin Ke said with a smile: "I happened to meet Mr. Chen at lunch today. I heard him mention your topic. I was also very interested, so I asked him to guide you.

Come and see me, Senior Chen also takes good care of me, so I can stand here. Don't dislike me, a freshman physics student, for coming to join in the fun."

These words were 70% true and 30% false, and Chen Licheng's authority in the team was immediately safeguarded.

Chen Licheng felt even more moved.

This junior is really good at being a good person. Chen Licheng has made a decision this time. Regardless of whether Qin Ke can help or not, at least he must remember Qin Ke's favor.

"Junior Qin has great experience in partial differential equations. I also wanted to brainstorm ideas, so I asked him to come and take a look." Chen Licheng explained a few sentences, and then took a few pages and handed them to Qin Ke: "This is what we are currently facing.

to the bottleneck part.”

The calculation and argumentation process in this part is not very long. It only takes about five pages in total, because it only discusses intraspecific attraction and interspecific repulsion.

Qin Ke looked through it quietly, and several people around him also looked at his face intently.

Those doctoral students finally realized that Qin Ke turned out to be a foreign aid!

But this Qin Ke is only a freshman. No matter how good he is in number theory, he can't be as proficient in partial differential equations, right? This is a problem that several of their doctoral students, including Professor Chen Licheng, cannot solve!

Some of them haven't understood that Qin Ke is a foreign aid, and they are a little unhappy with Qin Ke seeing their results, but they think that this part is just the failed and problematic content, not the team's scientific research results, and it was given to Qin Ke by Chen Licheng.

They just frowned slightly and didn't say anything.

To everyone's surprise, Qin Ke read quickly. He read the five pages filled with complex calculation formulas and argumentation processes in three minutes. After reading, he put down the paper, walked to the whiteboard, picked up a pen and meditated slowly.

I started writing slowly.

"???"

Including Chen Licheng, everyone has question marks on their minds.

How can you really read so many pages of manuscripts in three minutes? This is not a novel, but a very complicated and difficult mathematical formula that even an ordinary mathematics graduate student may not be able to understand!

They looked at the expressions written by Qin Ke with confusion, and found that Qin Ke's writing was very fragmented and scattered. He only excerpted the most critical expressions from a few pages of the manuscript - it is not accurate to say that the excerpts were taken, but it should be said that it was

Written silently.

Good guy, can you write it down by dictation after just reading it once?

Amid everyone's surprised and confused gazes, Qin Ke looked at these gestures for a while, then suddenly turned back and said with a smile: "Seniors, you should know about 'Zeno's Turtle', right?"
