The Poincaré conjecture is a fundamental proposition in topology, which will help mankind to better study three-dimensional space, and its results will deepen people's understanding of the nature of manifolds. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Like Han Xuan's current economic research topic, it has little relevance to 99.9999999% of the world's people, and it is difficult to access in daily life, but it is very important.

Ms. Fintana was skeptical of Isabelle's words, and she did not think that the young girl would be able to solve the Poincaré conjecture as she had said.

This problem of the century has plagued countless mathematicians for a hundred years, and countless people have rushed to participate in it, but finally failed.

But Han Xuan knew that Isabelli would definitely do what she said.

There weren't many things that bothered her in this mortal world, and the problems of science were one of them.

So when the knowledge has accumulated to a certain level, Isabelli frantically solves these problems, whether it is physics, astrophysics, finance, mathematics, biology, to pass the time and have fun.

She has a lot more time than ordinary people, and IQ aside, Isabelli is actually much smarter than Han Xuan.

This refers to in terms of academic research.

Isabelli is smart and smart, but to take a simple example, she can't tie her shoes, can't read a map, and often loses everything, while Han Xuan is more comprehensive.

Probably the difference between Einstein and Leonardo da Vinci, one only likes physics, the other likes everything, and studies everything a little.

It's hard to say who is better......

Isabelle went out on a phone call to gather the results of previous studies into the Poincaré conjecture, and then sat in the classroom again, listening like a normal student.

The boring course begins.

Han Xuan has no interest in simple equations, and this is the third time he has learned it before he is reborn, so it's no wonder that he can be interested.

For the first ten minutes, he was able to pretend to listen, and then he dozed off and sat there staggering, as if he was going to collapse at any moment.

The cameraman who caught him at the door had to cover his mouth so that he wouldn't laugh out loud.

Gabriel, who peeked at it, was already laughing so much that he couldn't straighten his waist, and it was usually difficult to see this embarrassing appearance of the little boss.

Shaking his hand to signal that he can't do it, let Owen come over and help watch, he has to go to the garden to laugh for a while, and he can't make too much noise......

Anya had no intention of attending classes.

She also brought textbooks with her when she went out to play, and Han Xuan or Isabelli would take the time to teach her, and now she has learned the lessons she has taken.

Turning his head to stare at Han Xuan's funny sleep at the moment, he bit his lip and held back a smile.

It feels like you're watching bad students who don't like to study, and only they sleep during class.

Teacher Fenata could pretend not to see at first, but when Han Xuan snored slightly because of her incorrect sleeping position, she could no longer ignore it.

stopped lecturing, and came to Han Xuan with a helpless expression on his face.

The lesson just now was like a lullaby, and it suddenly stopped, but Han Xuan didn't adapt, and when he fell forward, his head hit the table hard.

Immediately raised his head, sleepily looking left and right.

Seeing the math teacher in front of him, he smiled awkwardly and said, "It's my fault, sorry......"

"I know you've learned, but it means that my class isn't appealing to you, and I feel hurt. ”

Teacher Fintana was joking, pointing at Isabelle and continuing, "Look at your friend, she's serious.

It's just that the mind has flown out of the classroom, and I don't know where it is......"

This caused the students in the classroom to burst into laughter, and Isabelle came back to her senses to see that everyone was looking at her.

I vaguely heard the teacher call his name just now, and asked stupidly, "Sorry, what?"

……

"It's been a long time since I've slept so comfortably, and I really enjoy sleeping on my desk the most. Han Xuan's expression was lazy, and he stretched out and walked out of the classroom.

The recess in other middle schools is only three minutes, and Snow Mountain Middle School is very humane to give ...... Four minutes.

Classes are not in a fixed classroom, and each student is free to choose when and what class to attend.

The major courses are prescribed, and the credits are given according to the elective courses, and if you reach it, you will be able to graduate, but if you want to go to an excellent university, you are destined to be more diligent than others.

After the first math class, Han Xuan accompanied Anya to a foreign language class.

Surrounded by students in a hurry, some classrooms are far away, and four minutes is barely enough to trot.

One of the characteristics of Snow Mountain Middle School is probably the large pile of books they hold in their arms.

School bags are not allowed in the school, and when students enter the school building, they all leave their school bags in the cupboard at the door.

There is a tight time to change books between classes, so most students take all the books they need for the day with them from the first class.

A male student suddenly appeared in the girls' pile, and there was a camera to shoot with him, so he couldn't attract attention.

Wherever Han Xuan walked, the surrounding female students of all colors were densely packed and there would erupt into a commotion, causing many heads to poke out from the back-shaped corridor upstairs and downstairs.

It's too popular with girls, which makes him very distressed.

Dozens of half-grown little beauties blocked the way for him and Anya to pass.

also asked questions and boldly asked for contact information, which was simply delaying his study time, and he was about to be late.

There are also some senior girls who eat tofu, throw flattering eyes, pinch their faces and touch their hair, etc., obviously trying to soak themselves, which is really unbearable.

The environment of the school is relatively safe, and only two bodyguards came to follow from afar today.

Owen and Gabriel have a deterrent effect on adults in society, and these female students are not afraid of them, so the two can only let Han Xuan ask for more blessings.

Irving still had a heart to sigh: "I'm so envious, when I was a quarterback on the football team, I wasn't so popular." ”

"Yes, if I could be like him back then, I would definitely not lack a girlfriend. Gabriel smacked his lips in a tone of envy......

When Han Xuan struggled to squeeze it out, the new school uniform had been ravaged and a button had fallen off, and his hair was messy.

Even though I ran desperately to the classroom, I was still late when I arrived, and classes had already started inside.

The foreign language class was only 21 minutes, and now it is halfway over.

The teacher turned his head to look at Han Xuan, and took the lead in applauding and said, "It seems that there are two new students in our class, let us welcome them."

Han, did you just come back from the Gulf Battlefield?"

This was a joke about his messy look, as if he had gone to war, and then said, "As punishment, I would like to ask you to recite this article in German, otherwise you will only have to lose your midterm grades." ”

Han Xuan looked at the German on the projector and quickly read: "This night, the people there stood by the window, and from time to time, the snow under the moonlight was even reflected in the opposite side of the rose.

People watched intently, the livestock hitting the fence of the shed, and perhaps people were nodding their heads in the dark.

Bald men stood at the table, and two hours earlier, one of them had drawn a line with a red pen on a map.

There was a dot on the map, and this was the village, and then a man called, and then the soldiers erased the patches of color from the night: the village that burned with blood-red fire.

Wiped away, along with the screaming cats freezing in the rose-red snow......"

"I heard that you know what other languages you can speak, what do you do?

Why don't you try reading it again and give it to these students?

Also, the German just now is very standard, even more standard than me. ”

The female teacher laughed.

Han Xuanhui has a slightly more foreign language.

In addition to English, the official language of the United States, he speaks Chinese, Japanese, Korean, Mexican, French, German, Portuguese, Hindi, Dhivehi and, more recently, Arabic and Russian.

I read it quickly in these languages, and just as the class ended, the teacher and the whole class were dumbfounded.

Han Xuan smiled, took Anya's hand and ran away, and went to the next class...... (To be continued.) )
