The top student must be diligent

He couldn't help asking: "No way? Can you understand this?"

Xiao Yi replied: "Well... I didn't understand it just now, but I understood it after reading it for a while. Isn't the definition written here?"

"... Is it true?" Chen Wei didn't believe it. Xiao Yi understood it after reading it for a while, but he couldn't understand it?

Can the gap between people be so big?

So he took another look, "Riemann integral... The function f(x, y) is defined in the closed area D. Take any point (x, y) on the closed area D, and give the point (x, y) an increment vector in the positive direction of the axis..."

"What the hell is this!"

He covered his head and was a little frustrated.

However, when he turned his head again, Xiao Yi had already seen another page!

Please, do you have to be so exaggerated?

"No, brother, are you really sure you can understand it?"

Xiao Yi nodded while reading it, and said: "It's okay, and don't you think this is interesting?"

As he said, he turned the page.

Chen Wei: Damn...

I'm tired, destroy it, hurry up.

It turns out that the gap between people can really be so big! !

Chapter 19 This is what I want to learn

A monthly exam made Xiao Yi successfully "show his cards to his classmates, I won't pretend anymore, I am a top student".

Although he had already shown his cards a long time ago.

Of course, the news of this incident was not only spread in their class. With the announcement of the results of this monthly exam, he, as the first in the grade, was also quickly known to the whole grade.

The first in the grade who suddenly jumped up, and also surpassed the whole grade with a total score of 700, which was "the most powerful in the class", and left the second place - Shen Xing from the first science class 37 points.

For a while, Xiao Yi's name became the subject of discussion among students of the whole grade. Of course, because he appeared too abruptly, students of the whole grade thought that this person was a transfer student.

That is, the kind of student who originally studied in a good school in another place, and then had to return to his hometown school to take the college entrance examination because the college entrance examination must be taken in the place where the household registration is located.

If he was not such a transfer student, how could this guy have such a great result?

But the problem is, they are only in the second year of high school!

There is still more than a year before the college entrance examination. How could such a transfer student transfer back now?

So soon, the fact that Xiao Yi was a transfer student was proved to be false.

Because the score sheet still showed the improved ranking compared with the previous exam, and Xiao Yi's "+98" in this box was fiercely pierced into the eyes of everyone in the grade.

This fully shows that this person is not a transfer student, but a dark horse.

With further digging, the news that Xiao Yi was the student selected by the junior class was finally lifted by the two grade directors and began to spread.

For a time, Xiao Yi was not only watched by his classmates, but also by students from other classes.

Their time in the second year of high school was not as tight as that in the third year of high school, so these students still had such leisure to witness what a super academic master who could get a total score of 700 in the monthly exam and could also be in the junior class looked like.

Naturally, Xiao Yi also received unanimous praise from the girls in each class.

"Don't look at him as if he seems a little unkempt and stupid. Once he starts studying, he is so handsome."

"Is this a science and engineering boy? He looks so handsome when he thinks. Ah, I am going to fall in love with him!"

"I really want to know what he thinks in his mind when he is studying. It must be hard for ordinary people like us to imagine, right? As a girl, I envy boys like him."

"..."

"Go away!"

Xiao Yi pushed Chen Wei aside speechlessly, "I still have to study!"

"Hey, hey, hey, I haven't finished yet." Chen Wei said teasingly: "During the breaks, I stood outside and carefully wrote down what the girls said."

As he said, he continued to say in a tone imitating a girl's voice: "Oh, our super academic bully is so handsome, I really want to get to know him!"

Xiao Yi pulled the corner of his mouth, weird, right?

He immediately asked back: "Are you jealous?"

Chen Wei immediately got angry like a cat whose tail was stepped on: "You are slandering me!"

"Would I envy you? Even if I fall to my death or jump off here, I will not envy you!"

"It's just a few girls! If I didn't focus on studying, if I dressed up well, the girls chasing me would surround our class!"

The man below!

Xiao Yi looked at him with contempt.

"What are you looking at!" Chen Wei got angry again.

Xiao Yi picked up the draft paper next to him, wrote on it, and then handed it to Chen Wei, saying: "Since you said you focus on studying, then write this question."

"Write it..."

Chen Wei took a look at the question.

[What is the sum of the horizontal coordinates of all the intersection points of the graph of the function y=1/(x-1) and the graph of the function y=2sinπx? 】

Finally, "Uh, ahem, I'm going to the bathroom, we'll talk later."

After that, Chen Wei ran away.

Xiao Yi breathed a sigh of relief, finally, it was quiet around him.

Next time this guy comes to cause trouble, I'll give him a math problem.

He lowered his head and continued to read the book "Mathematical Analysis" in his hand.

Although he only got the book this morning and only three classes have passed so far, he has already finished more than half of it.

The reason is very simple. He reads this book whether in class or after class. In addition, some of the knowledge in this book is actually what he has learned in high school mathematics, so he reads it very quickly.

As for why he can read this book during other classes, it is "teacher privilege".

Because the junior class has ensured his future, and the test results of this monthly exam also make him basically not worry about the college entrance examination. At the same time, there is Liu Bin's expectation for him-before officially enrolling, he can complete all the mathematics subjects during the undergraduate period, so Xiao Yi has obtained the privilege of learning mathematics by himself in any class.

In this way, after reading three classes in a row, he has read so much of this book, and it is only a matter of lunch break to finish it.

Their school does not force lunch breaks, so even during lunch breaks, he can study by himself to avoid wasting time.

After finishing this book, I will read advanced algebra, and then the book "Analytical Geometry".

It is expected that I will be able to finish reading all of them before tomorrow afternoon!

...

In fact, Xiao Yi reads faster than he thought, because after the BUFF upgrade, his reading speed has increased by 20% compared to before, so he had already read "Analytical Geometry" before the last evening self-study class that night.

And he finished reading this book when he was only in the second class of the next morning.

Then, he started to study the fourth book, "Abstract Algebra" without stopping.

Now he is deeply fascinated by these new knowledge.

These new knowledge are more in-depth than high school knowledge, and there is a certain degree of difficulty in understanding - although for Xiao Yi, these difficulties are not worth mentioning, but it is still much better than those high school knowledge that has gradually made him drowsy.

Especially abstract algebra, this book is not thick, but it is much more difficult.

According to Professor Liu, mathematical analysis may be the most difficult thing for him when he first started learning it, but in fact, the difficulty of mathematical analysis lies mainly in the change of thinking. They need to convert the mathematical thinking in high school.

However, changing thinking has never been difficult for Xiao Yi, so in his opinion, mathematical analysis is basically not difficult to understand except that the amount of calculation is more than other courses.

Only abstract algebra made him understand what Liu Bin told him at the beginning, which is truly at the forefront of mathematics.

"This is what I want to learn~"

As Xiao Yi finished reading the book on abstract algebra, he closed his eyes in ecstasy, as if he felt an intracranial orgasm.

Chapter 20 Academician's Interest

In the conference hall of a Shangri-La Hotel in Shangjing, a banquet was being held.

This is a mathematics academic conference held by the China Mathematical Society. The participants include mathematics professors from various universities across the country, or related research institutes, societies, etc., mathematics enthusiasts and mathematics students who have registered for the conference, etc.

There are too many such academic conferences for the mathematics community, and they are even too frequent.

Of course, for these scholars and professors who study mathematics, they like to attend such conferences.

The reason is very simple, because if they don't attend academic conferences, they basically don't know what they can do in their daily life.

Do projects?

They do this, but the saying about mathematics is the same for any person who studies mathematics in the world - if you don't know how to do it, you can't learn it no matter how hard you try.

So sometimes, the cycle of a mathematics project is often very long, even starting from one or two years.

When they are not studying projects, they usually have free time, so they might as well attend academic conferences. Maybe they can listen to other people's reports and communicate with other friends, and then they will have some ideas for their own projects?

What's more, attending academic conferences can legitimately spend project funds, which has basically always been one of the main expenditure items for mathematics project funds.
