Learn

Mathematics?

The boat was slightly stunned.

After a moment's silence, he began with a slight cough.

"Computational materials is also a kind of Mathematics..."

"I don't want to learn computational materials," Han Mengqi shook her head stubbornly. "I just want to learn mathematics."

As if she didn't think her expression was very accurate, she added another one immediately after.

"I mean, pure mathematics."

"Pure mathematics..."

Hearing this request, the boat suddenly felt a big head.

Although it's reasonable to say that he doesn't really want to talk about other people's ideals

But

Put down the ballpoint pen in his hand, cross his fingers on the desk, and Lu Zhou looked at Han Mengqi seriously and asked.

"Can you tell me the reason You have been studying computational materials for three years. Why do you choose to study pure mathematics at this time? "

Generally speaking, it's very common to study other applied mathematics subjects from pure mathematics, but it's rare to study pure mathematics from this applied mathematics subject.

And if it's someone else, that's all. But of all the students who study computational materials, Han Mengqi is the most gifted and satisfied one.

Even Jericho, who has gone to MIT to study in Bo, is not necessarily better than her in talent.

It's impossible to say that he doesn't feel sorry at all when he wants to study a new field of computational materials.

After all, Lu Zhou devoted a lot of effort to her cultivation.

Facing the serious eyes of Lu Zhou, Han Mengqi slightly moved his eyes away, hesitated for a moment, then said with some complicated tone.

"I don't like chemistry at all The reason why we chose chemistry was just because of the adjustment. In fact, I originally planned to transfer to mathematics major. As a result, you got an undergraduate training plan at JINDA. I was just in the top of the grade points in the Department. After being told a few words by the director, I was confused to sign up... "

Maybe she felt that her reason was so naive that she was embarrassed to go on.

Adjustment?

There was almost no old blood gushing out of the boat.

Little sister Oh no, little sister, you are graduating from the master's degree. Is the old yellow calendar really suitable?

"It's nothing to adjust, isn't it? My math major is also adjusted, "Lu Zhou tried to persuade with a look of crying and laughing." the key is not to adjust, but to adapt - "

" not to adapt, "Han Mengqi shook his head, looked at Lu Zhou carefully, and said," but like it or not. "

Looking at her serious eyes, Lu Zhou was slightly stunned.

It seems to be the first time she has refuted her point of view

After a while of silence, Lu Zhou recalled what he had said, and finally sighed and said.

“…… You are right. Interest is the best teacher. "

Regardless of the systematic factors, he really likes to study mathematical problems and the feeling of immersing himself in the mathematical world, so that he can choose mathematics as the direction of his struggle.

If his students really like mathematics

He did not stop her position.

Even in his opinion, computational materials are more suitable for her than mathematics.

Hearing that Lu Zhou agreed with her idea, Han Mengqi's face burst into a smile and said happily.

"That --"

"I won't stop you," continued Lu Zhou, looking at Han Mengqi, who was full of joy. "But my doctor is not so good Especially pure mathematics. "

Slightly pursed the next lip angle, Han Mengqi said firmly.

"It doesn't matter I will try. "

“…… Some things can be done with more than effort. Mathematics is a discipline that tests talents, especially pure mathematics. There are many people engaged in the research in this field, but few of them can really make achievements. Some people are poor in their lives, but also just learning and summarizing the knowledge of predecessors, far from creating. "

With that, Lu Zhou took out a piece of straw paper from the table, picked up the ballpoint pen on the table, conceived it for about ten seconds, and wrote a line of calculation on the paper.

[for any real number s > 1, define ζ (s) = ∑ 1 / (m ^ s) ]Looking at this formula, Han Mengqi slightly wrinkled Qiong's nose.

"Is this...?"

It looks very simple.

"Riemannian zeta function," replied the boat lightly

With that, he wrote down the last part of the question.

【…… It is proved that ζ (2n) is the transcendental number. ]Hearing the two words of Li Man, Han Mengqi, who was still thinking about the problem and seemed to be very simple, immediately got a thrill and said with fear, "will you give me such a difficult assignment as soon as you come up?"

"Don't be afraid to hear Li Man. You live in the future 150 years after he died." Lu Zhou smiled and handed the super high self to Han Mengqi. "Besides, it's not homework, it's exam."

“…… Examination? "

"Yes," Lu Zhou nodded. "If you can solve this problem, I will allow you to study for a doctor's degree in pure mathematics here."

At this point, he paused for two seconds, then added a sentence later.

"Of course, if you change your mind and want to read computing materials, the door of my office is still open to you."

After all, Lu Zhou was quite satisfied with her paper on topological crystal insulator. If the little girl can get out of the way and come back to study the computational materials, of course, he is quite welcome.

Want to learn pure mathematics

This thing is not so easy to learn.

Staring at the draft paper in his hand, looking at this line of calculation and the problem of seeking transcendental number, Han Mengqi felt numb.

Don't say how to solve it. She didn't even know the problem.

In the past, when she studied the problems of computational materials, the mathematical methods she used were basically focused on functional analysis, geometry and topology, such as the knowledge of analytic number theory, which she didn't remember even if she had heard it

However

If I give up like this, it's not like her.

After biting his teeth, Han Mengqi raised his head and stared at Lu Zhou.

"Don't expect me to go back I'll start by collecting information. "

"Why, I'm looking forward to your answer," Lu Zhou continued with a smile. "But your time is only two months. I hope you can give me an answer before the end of the year."

"Hum, where can I use it for two months? One month is enough."

Han Mengqi, with this piece of paper, turned around and walked away.

After the door opened and closed, the office returned to the quiet, only to hear the sound of brush.

After sitting in the office chair and thinking for a long time, Lu Zhou suddenly looked up at he Changwen, who was sitting at the table not far away from him - the pure doctor of mathematics he was taking now, and asked.

"Chang Wen, if you can prove that ζ (2n) is a transcendental number, you can think of several ways."

He Changwen stopped his pen and hesitated for a moment. Then he pushed his glasses on the bridge of his nose with his pen cap in the back and said.

"I Maybe I can think of a No, there should be two ways. "

The last half of the sentence, after a moment of hesitation, was said in a positive tone.

With his ability, this sentence should be true.

The boat nodded and said briefly.

"Two are good."

He Changwen hesitated a little and asked, "is it too difficult for a master's degree student?"

Although he didn't listen to the conversation between the professor and the postgraduate just now, he heard some passively.

For those who have not been exposed to pure mathematics in the undergraduate and master's stages, it is really a little too difficult to challenge such a difficult problem.

This is not only the lack of mathematical methods, but also the need to test a kind of thinking of learning pure mathematics. These things, for a beginner, are not easy to cross, let alone a layman who has not yet started.

The boat smiled faintly.

"At the doctor's stage, it's time to learn to ask questions and find solutions."

"If she can come up with a different way than the standard answer, it's the best."

"If she can't think of it, it only means that she doesn't have the talent in this field. It's better to carefully reconsider the future road."
