I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 411 Song Yao: Do ​​you want to try something exciting?
on Monday.

Xu Qingzhou stood at the door of the classroom, looking at the lively scene in the classroom, with an expression of surprise on his face.

Last time there were only about twenty people, but this time not only was the seat full, there were people even standing in the corridor.

Occasionally, you can see a few middle-aged faces in the crowd, who appear to be professors and scholars from MIT.

It's quite popular.

As Xu Qingzhou walked in, the originally noisy classroom suddenly became quiet.

Everyone's eyes were on him.

Xu Qingzhou walked up to the stage with a calm expression, "Good afternoon, everyone. I'm glad that so many people are interested in my class."

He did not change the pace and content of the class because of the extra people.

"As of this morning, I have received six answers to last class's homework. As far as the results are concerned, there are no problems. I have already written down some areas that can be improved in the email. Now, it's time to listen to my ideas."

Xu Qingzhou took a marker and wrote down a row of formulas, saying, "First, I will consider starting with the summation on the right side of equation (8) above. Of course, for better generalization, I will replace ψ(x) with any function F defined on positive real numbers ≥ 1."

"."

In just over ten minutes, several rows of formulas appeared on the whiteboard.

Many people nodded slightly below the podium, sighing that he was worthy of being the master who solved the three prime number conjectures.

The verification is simple, the logic is clear, and there is no unnecessary step in the whole process.

Just talking about the calculation process, it is much better than theirs.

These are the thoughts of the bystanders.

As for the students who attended the class last time, quite a few of them were already struggling and could not keep up with Xu Qingzhou's pace.

However, Sun Simin was not included here. What surprised Xu Qingzhou was that she was the first person to send an email.

As for the steps, there are a lot of redundancies, but the result is okay.

Just like the answer to the question is D, she is ABABECRD.

Xu Qingzhou is directly ABCD.

But overall, Xu Qingzhou is quite optimistic about this girl. Although she looks a little dull, she is talented and willing to work hard.

"The right side is the most difficult to process, so we separate the innermost summation and process it separately."

Xu Qingzhou's voice echoed in the classroom.

He went a little deeper and went over the proof of the prime number theorem.

The audience was paying close attention.

30 minutes later, Xu Qingzhou entered the second part, which was Gauss's research on the distribution of prime numbers in arithmetic series and Xu Qingzhou's own research on the distribution of prime numbers in arithmetic series when proving the twin prime theorem.

After all, to study prime numbers, one cannot avoid the issue of their distribution.

By this part, the people who had barely understood what was said just now began to lose track of Xu Qingzhou's train of thought and turned into ruthless camera machines.

Xu Qingzhou also noticed this change, but he also did not deliberately slow down.

The current content is indeed hellish for freshmen, but in his opinion it is only because of the large amount and it takes some time to digest.

Some people acted like fools in the last class, but they understood some of the previous content in this class.

Moreover, a certain level of intensity can just screen out those who just want to cheat for credits.

In the corner, ever since Xu Qingzhou started to talk about new content, Mars, who had complained about the simple things in the last class, gradually fell into a state of listening to a foreign language.

He looked at the friend next to him, "James, do you understand?"

"I originally thought that Professor Norwich's mathematical analysis class was quite perverted, but now I find that Professor Norwich is very kind."

Mars nodded in agreement.

"That's all for today, thank you everyone."

Seeing that the time was almost up, Xu Qingzhou put down the marker.

Ninety-nine percent of the questions are correct, but some of the questions asked by this group of young people can really make people think of something new.

For example, a guy named Dino Connolly just asked a question about the statistical law of deviation of prime numbers.

Interesting.

Let Xu Qingzhou consider whether he should focus on studying the law that the distribution of prime numbers alternates between "short intervals" and "long intervals".

Perhaps the solution to the Riemann hypothesis lies in it.

Xu Qingzhou couldn't help but think of Horn's joke last time.

The class passed like this.

Before the get out of class ended, Xu Qingzhou emphasized one last time: "I think it is necessary to remind the students who have chosen this course. If you are interested in prime numbers, you are very welcome, but if it is for credits."

"I suggest you change to other courses before the course selection ends. Otherwise, I can only say with regret that this semester will be very difficult. And, believe me, the probability of getting credits will be lower than the probability of God throwing the dice and hitting you."

There was a sudden murmur from the audience, and many people began to feel confused.

Xu Qingzhou didn't care and waved his hand to signal everyone to end the get out of class.

As soon as he finished, a young man came up with a manuscript and said, "Mr. Xu, I have a question I want to discuss."

Xu Qingzhou took a look and saw that it was about the growth problem of Euler function.

The Euler function is disgusting to many people because its graph seems to be disorganized and confusing.

The growth law of number theoretic functions themselves is very elusive, so many mathematicians will first discuss the average growth law of number theoretic functions.

But that doesn't seem to work here.

Xu Qingzhou thought for a moment and said, "Generally speaking, the appearance of asymptotic formulas will appear in the order of interchangeable summation. Perhaps, here we can expand the Euler formula into some kind of summation, and finally... I think we may use the Moebius inversion."

The young man pondered for a long time, then nodded excitedly, "Oh, Xu, your idea is really great."

"Mr. Xu, I heard that you are currently studying the Riemann hypothesis. Here are a few pages of research on the Riemann function." A middle-aged man came up.

Xu Qingzhou took a closer look and then began to check the calculations on the whiteboard.

It really feels a bit like an academic exchange meeting.

Rows of complex formulas soon appeared on the whiteboard.

The result is just three words: it doesn’t work.

The get out of class is over, but there are still quite a lot of people in the classroom.

Sun Simin and others wanted to broaden their horizons. Even though they couldn't understand what was being said, they felt a sense of grandeur and elegance as they were discussing philosophy.

This is what a top university should look like.

It wasn't until 40 minutes later that the classroom finally quieted down.

Several scholars thanked Xu Qingzhou and left with satisfaction.

When Xu Qingzhou was putting away his manuscripts, he noticed that Sun Simin was still there.

"Senior Xu, I have two difficult problems here, and I haven't been able to solve them after spending a long time trying to solve them." Sun Simin said timidly.

"Are you still planning to continue attending the class?"

Xu Qingzhou took the manuscript and asked with a smile. This girl said before that she was here to get credits.

"Well, now I suddenly think that prime numbers seem to be quite interesting."

Sun Simin said embarrassedly.

"Then you must be prepared to endure hardships."

"I can endure hardship."

The question is not difficult. It requires deriving the fundamental theorem of prime numbers from the sieve of prime numbers.

10 minutes passed.

After Xu Qingzhou finished answering the questions for Sun Simin, he went to Professor Roberts to ask two questions.

The first one was about complex functions, the power series problem he thought of when he was looking at Weierstrass's series path.

The second is the sequence of real numbers, which is related to his current research on Landau-Siegel zeros.

This side, Professor Morton's office.

At the desk, Professor Morton was staring at the paper on the screen with a serious and meticulous expression.

Opposite her was a young man of twenty-five, standing there obediently.

"Well, we can move on to the next step."

Professor Morton checked the analysis report and nodded.

The young man breathed a sigh of relief. Before leaving, he glanced at Song Yao, who was reading a book with her head down, and was a little surprised.

"Huh, I finally passed." The young man walked out the door and let out a long breath. He just happened to see Kelly standing next to him, so he invited her, "Hey, Kelly, let's go have a drink together?"

"I have an appointment," said Kelly.

"Well, I'd rather invite the girl next to Professor Morton to drink with you than to have a drink with you. But I see she's wearing a ring. Does she have a lover?"

"Yes, I have a boyfriend, and they love each other very much."

Kelly stopped, turned around and warned, "Don't have any illusions. You... don't have any hope."

After saying that, she strode downstairs.

Beauty has no nationality. Even she, a foreigner, thinks Song Yao is very beautiful.

Her friend has a completely different style in front of her boyfriend. She is a little cold and aloof.

This may be what love is, being gentle to only one person.

If Xu Qingzhou knew that she used the word "gentle", he would definitely cry.

It was obvious that he was the only one being violent!

The young man shrugged. He was used to being beaten by Kelly. He caught up with Kelly and said, "Boyfriend? I'm curious about what kind of boyfriend you are."

“Excellent,” said Kelly.

"Oh? Do I know him?" the young man was even more curious.

"know."

Kelly said that she remembered Granville Xavier had talked about Xu Qingzhou before, and lamented that this Xia countryman was so powerful.

"Xu Qingzhou." Kelly didn't keep the secret.

"Xu Qingzhou?"

The young man was silent for a long time, then he sighed slowly: "That's really great, let's go have a drink tonight?"

"Don't go."

"I'm sad."

At the same time, inside the office.

Song Yao was reading "Microeconomic Theory: Basic Principles and Extensions" with a cold expression on his face, and his long eyebrows trembled slightly as he was thinking about something.

The fingers holding the pen are slender, and under the light, the fingertips seem to glow.

Next door, the old lady pushed her glasses and her usually frowned brows relaxed.

"It's very well written, even perfect. What are your next ideas?"

Song Yao stopped writing and briefly described her thoughts on the fourth part: "There are three directions"

8 pm.

When Xu Qingzhou returned, Song Yao was lying on the sofa playing with her cell phone, probably chatting with a girl from China.

School beauty Song wore a white suspender, revealing her smooth calves.

Two legs together, very tempting.

"I am back."

"Um"

Xu Qingzhou walked into the living room and immediately smelled a faint fragrance. He immediately realized that School Beauty Song had taken a bath.

"Have you finished writing the third part?" Xu Qingzhou asked with a smile as he put his things away.

He knew that Song Yao was going to talk to Professor Morton about her thesis today.

"Well, it's done." Song Yao nodded and stretched, the clothes on her chest swaying with the movement.

Xu Qingzhou was a little suspicious that this girl was trying to seduce him.

calm down.

Xu Qingzhou took a deep breath. Usually he was the one who was impatient, but today it was finally School Beauty Song's turn. Things must have changed.

He spread out the manuscript and thought about the distribution of several twin prime numbers during the afternoon class. He simply took notes and planned to improve it in the evening.

At 9 o'clock in the evening, after finishing his notes, he went to take a shower consciously.

Ten minutes later, Xu Qingzhou went over to the sofa and squeezed together with Song Yao.

But Song Yao sat up and gave Xu Qingzhou the first slap on the sofa.

"Hmm~"

half an hour.

The two people separated and put their faces together.

"Whoo~"

Xu Qingzhou stared at Song Yao with resentment: "You have ruined me again."

Song Yao put one hand on the sofa and hooked Xu Qingzhou's chin with the other hand, "Do you want to try something exciting?"

"???"

What kind of overbearing CEO behavior
Xu Qingzhou was a little confused and didn't react for a while.

What's going on? Did I cultivate School Beauty Song?!

Wait, he didn't act rashly. He suspected that Song Yao was fishing and just wanted to find a chance to beat him up.

Song Yao can still do this kind of thing.

This girl often does things unconventionally.

but.
Although I doubt Song Yao's motives, it's rare to see her like this.

The royal sister version of Song Yao.

However, Xu Qingzhou still asked tentatively: "Is it the kind of excitement I think?"

"It's more exciting than you think."

Song Yao licked the corner of her mouth and even used a queen-like voice, "Teacher Xu, do you want to?"

"miss you!"

Xu Qingzhou swallowed and nodded. Although he felt that it might be a trap, he couldn't tolerate it.

Even if it's a pit, I'll jump in!
Song Yao raised her eyebrows: "Then let's start."

"I am ready."

Xu Qingzhou nodded seriously, looking forward to it.

10 minutes passed.

Lying on the sofa, Xu Qingzhou stared at the ceiling, feeling hopeless about life and secretly sighing that his sharp sword was becoming outdated.

"Xu Qingzhou, can you do this?"

Song Yao was very happy and pinched Xu Qingzhou's face.

Xu Qingzhou felt offended, took a deep breath, and moved his arms, "I don't believe it, come again!"

"Oh, come on."

then.

The two started the second game.

"Double kill!"

"Triple Kill!"

"Quadra Kill!"

The sound of a quad kill from Song Yao's phone rang out in the living room.

Not long after, the second game ended.

Xu Qingzhou's shooter was once again led by Li Bai, the school beauty of Song.

"Facts have proved that I am suitable for being a gigolo." Xu Qingzhou put down his phone and stopped struggling.

"Then I'll try harder."

Song Yao raised her eyebrows again, in a good mood, looking at the results of the night, and said: "I will try to make you eat soft rice as soon as possible."

It really feels good to fly with Xu Qingzhou.

After playing the game, Song Yao happily chatted with Zhang Qiong.

Xu Qingzhou held up the legs of the school beauty Song and looked through the manuscript he had discussed with Professor Roberts in the afternoon.

10pm.

Song Yao put down her phone, and seeing that Xu Qingzhou didn't react, she rubbed Xu Qingzhou's thigh with her foot.

"Don't disturb me while I'm studying."

Xu Qingzhou said without raising his head.

"嘁~"

Song Yao snorted and tried to pull her legs back, but was pinched by someone again.

Song Yao pursed her lips: "Let's play something exciting?"

"Again?" Xu Qingzhou expressed his doubt.

Song Yao speaks with actions.

puff~
When he looked again, Xu Qingzhou had been pressed down on the sofa by Song Yao.

"."

Xu Qingzhou felt helpless.

In order to be lazy, School Beauty Song has been pretending to be weak for several days. Including her period, it has been more than ten days. Tonight is destined to be a fierce battle.
