The Poincaré conjecture is a proposition with basic significance in topology, which helps humans better study three-dimensional space. The results it brings will deepen people's understanding of the nature of manifolds.

Like the economic research topics currently conducted by Han Xuan and others, it has little to do with 99.9999999% of the people in the world and is difficult to get in touch with in daily life, but it is very important.

Teacher Fintana was skeptical of Isabelle's words. She did not think that the young girl could solve the Poincaré conjecture as she said.

This century-old problem has plagued countless mathematicians for a hundred years, and countless people have successively participated, but ended in failure.

But Han Xuan knew that Isabelle would definitely do it when she said it.

For her, there are not many things that can bother her, and the various problems in the scientific community are one of them.

So when the knowledge accumulated to a certain level, Isabelle frantically solved these problems, whether it was physics, astrophysics, finance, mathematics, and biology, so as to pass the time and have fun from it.

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

This refers to academic research.

Isabelle is smart, but to give a simple example, she can’t tie her shoelaces, look at maps, and often loses things, and Han Xuanze is more comprehensive and comprehensive.

It is probably the difference between Einstein and Leonardo da Vinci. One only likes physics, the other likes everything, and has a little research on everything.

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

Isabelle went out and made a call to collect the results of previous research on Poincaré's conjectures. Then she sat in the classroom again and listened like an ordinary student.

The boring course has begun.

Han Xuan had no interest in simple equations. Before he included rebirth, this was the third time he learned it, so it would be strange if he was interested.

In the first ten minutes, he was able to pretend to listen, then he started to doze and sat there swaying, as if he would fall down at any time.

The cameraman who photographed him at the door had to cover his mouth so that he would not make him laugh out loud.

Gabriel was peeking at her, and she couldn't stand up straight. It was difficult to see the boss's embarrassing appearance.

He shook his hand and signaled that he couldn't do it anymore, so he asked Owen to come and help him watch. He wanted to go to the garden to laugh for a while. It was too uncomfortable not to speak...

Anya didn't want to attend class.

She also brought her textbooks when she went out to play. Han Xuan or Isabelle would take time to teach her. Now she has learned the courses she is taking.

He turned his head and stared at Han Xuan's funny sleeping look at the moment, biting his lips and holding his smile.

It feels like watching bad students who don’t like to study, and only they will sleep during class.

Teacher Finnata could pretend to be invisible at first, but when Han Xuan snored slightly because of the incorrect sleeping position, she could no longer ignore it.

He stopped giving a lecture and came to Han Xuan with a helpless expression on his face.

The lesson just now was like a lullaby, and suddenly stopped. Han Xuan was not used to it. When he fell forward, his head hit the table hard.

Immediately raised my head, and watched from side to side with sleepy eyes.

When he saw the math teacher in front of him, he smiled awkwardly and said, "This is my fault, sorry..."

"Although I know you have learned it, it means that my class is not attractive to you and I feel very hurt."

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

But the mind has already flown out of the classroom, I don’t know where it is…”

This sentence made the students in the classroom burst into laughter, and Isabelle came to her senses and saw that people were looking at her.

Just now, I seemed to hear the teacher called his name and asked stupidly: "Sorry, what?"

...

"It's been a long time since I've been so comfortable in sleeping. It's true that I'm lying on the desk and sleeping the most enjoyable." Han Xuan looked lazy and stretched out of the classroom.

The rest time between classes in other middle schools is only three minutes, and Xueshan Middle School gives four minutes very humanely.

Classes are not in a fixed classroom, and every student has the freedom to choose when and what class to take.

The major subjects are specified, and credits are given according to the elective courses. Once you reach it, you can graduate. However, 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 take a foreign language class.

There are students walking in a hurry, and some classrooms are far away, and four minutes are too long and need to trot.

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

Schools are not allowed to bring schoolbags. When entering the teaching building, students put their schoolbags in the cabinet at the door.

It is very tight to change books during class, so most students bring all the books they need to use today from the first class.

A male student suddenly appeared in the crowd of girls, and there was a camera shooting. It was impossible not to attract attention.

The place where Han Xuan walked was densely surrounded by female students of all kinds of skin, and a burst of idiot-like disturbances would erupt, causing many heads to pop out from the back corridor upstairs and downstairs.

It was so popular among girls, which made him very upset.

Dozens of half-year-old beauties blocked the way and prevented him and Anya from passing.

I also asked questions and asked for contact information boldly. It was simply delaying my study time and was about to be late.

There are also some senior girls who eat tofu, flirt with their eyes, pinch their faces and touch their hair, and they clearly want to soak themselves, and they really can't stand it.

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

Irving and Gabriel are intimidating to adults in society. These female students are not afraid of them. The two of them can only let Han Xuan ask for more blessings.

Irving still thought about it and said: "I'm so envious. When I was a quarterback in the football team, I wasn't so popular."

"Yes, if I could be like him back then, I would definitely not be short of a girlfriend." Gabriel smacked his lips, and his tone was envious...

When Han Xuan went through a lot of hard work, the new school uniform had been ravaged and his hair was messy.

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

Foreign language classes are only twenty-one minutes long, and now half of the time has passed.

The teacher turned his head and looked at Han Xuan, and clapped first and said, "It seems that two new classmates have come to our class, so let us welcome them.

Han, have you just returned from the Gulf battlefield?"

This is teasing his messy look, like he went to a war, and then said, "As a punishment, I want to ask you to recite this article in German, otherwise you will be deducted from your midterm results."

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

People stared at the sight of the livestock slamming against the fences of the sheds, and perhaps people were still nodding their heads in the dark.

The bald men stood by the table, two hours ago, one of them drew a line with a red pen on a map.

There is a point on the map, which is the village. Then a man called, and then the soldiers wiped out the color blocks in the night: the village burning with blood-red fire.

The cats that were crying in the red rose snow were wiped out together…”

"I heard that you know the languages ​​of other countries, what do you know?

Can you try to read it and listen to these students?

Also, the German language just now is very standard, more standard than mine.”

The female teacher smiled.

The Korean Propaganda Conference has a little more foreign languages.

In addition to the official American language English, he also knows Chinese, Japanese, Korean, Mexican, French, German, Portuguese, Indian, Divighi, and also recently learned Arabic and Russian.

I quickly read it in these languages, and the get out of class just ended, and the teacher and the whole class were stunned.

Han Xuan smiled, took Anya's hand and ran away, going to the next class (~^~)
