Familiar!

The more you look at it, the more familiar it becomes!

Ignoring the chaotic crowd and discussions, Zhang Ye retreated into the distance, found a place where no one was around, opened the game interface quietly, bought a "memory search capsule" in the mall, and ate it on the spot without hesitation, his eyes scattered, and he suddenly fell into memory.

……

Another Earth.

It was in high school.

In the past, the school was closed on Friday afternoon, but it may be a requirement of the education department, in the second half of the year, Friday afternoon became an interest training class, and every student had to apply for a class. The lecture is not about exam-taking courses, but about expanding knowledge.

This is the Fermat conjecture, one of the world's three major mathematical conjectures, after more than 300 years of history, it was finally proved in 1995, so it is not called a conjecture now, but Fermat's theorem. ”

"Teacher, can you tell us more about it?"

"Hehe, I have a detailed explanation here, I put it on the projection, you can take a look at it casually, in fact, you can't understand it, well, teacher, I don't have this level to speak, the deduction process of this theorem is extremely complicated, and my level is limited. ”

"Wow. ”

"Or in Chinese and English?"

"It's so profound, it's amazing!"

"Huh, you see?"

"Uh, I don't understand it at all!"

……

The man returned, and his eyes were opened.

Zhang Ye still had a confused look in his eyes before, but now he was extremely clear, he said how could he be so familiar, what Dell conjecture Asus conjecture or IBM conjecture! Isn't this just a different name! Because the person who put forward this conjecture in this world is called Dell, so the name of the conjecture is also called Dell, but the content of the conjecture obviously has nothing to do with the name, this Dell conjecture is exactly the same as his Fermat conjecture on the earth!

It's the same thing!

The conjecture is the same!

The only difference is that on this earth, this conjecture has not been cracked by the world's mathematicians, and it has only been proposed for a few decades, while in Zhang Ye's former world, the world's mathematical problems have been revealed, and the Fermat conjecture, the four-color conjecture and the Goldbach conjecture were called the three major conjectures in mathematics at that time!

Zhang Ye glanced at the American-Chinese mathematician.

A mathematician named Louis was closing his eyes.

Another young mathematician named David ran to the Frenchman's booth and chatted with a French female mathematician, as if she was picking up girls.

As for the young contestants from the United States this time, they won the championship, which made them all proud and smiling.

Zhang Ye sneered.

Dale guessed?

He picked up his mobile phone, found Wu Zeqing's name, and sent a text message, "Old Wu." ”

Wu Zeqing, who was far away, turned his back to this side, as if he was still looking at the jade wrench, but there was no response, it was estimated that there were too many people and the voice was too noisy, so he didn't hear it.

Zhang Ye made a phone call, rang a few times and hung up.

He saw that Wu Zeqing noticed the phone and picked it up.

After a moment or so, the reply was: Hmm.

Zhang Ye sent: Do you like that jade wrench?

Wu Zeqing: Hehe, make do.

Zhang Ye: That's what I like very much.

Wu Zeqing: They won't sell, even if they do, the eldest sister can't afford it, this should be an old object in the palace before, and it is worth a lot of money.

When Zhang Ye saw it, he said: Okay!

Wu Zeqing: ?

Lao Wu obviously didn't understand what he meant.

Zhang Ye didn't reply, put away his mobile phone, and squeezed towards the crowd.

……

Inside the venue.

Wang Yiming, as the team leader, had already walked to the American-Chinese-Chinese booth, and Xin Ya and Han Henian also followed and protested sternly against the old American mathematicians in English.

Wang Yiming said: "Why do you want to use our country's things for the prize?"

Lao Mei's team leader, mathematician Louis looked at him, obviously they knew each other, and everyone was no stranger to each other, "Wang, this is our thing." ”

Wang Yiming said: "Can I understand that you are provoking?"

“NONONO。 Louis said: "This thing is the legacy of a teacher of our Mathematical Association, he donated some items to the association before he died, for the promotion and research of mathematics, I don't know the origin of this thing, but now he is not yours, the ownership is ours, we have the right to dispose of it, use it, there is no other meaning and intention, do not misunderstand." ”

Xin Ya said: "But you have already made us misunderstand!"

David, the mathematician who was picking up girls over there, also came back, "What happened?"

Wang Yiming pointed to the question board, "You change the topic, let's have a fair competition in the field of mathematics." ”

“NO。 Louis shook his finger, "That's our problem, Wang, we've been working on the Dale conjecture, and we want to use this world's math puzzles to communicate with mathematicians from various countries, what's wrong with that? There's nothing unfair about that, and the game is over, our team has won the final victory, that's the result of the game, there's no other competition." ”

David also spread his hands and smiled: "It's a pity. ”

The competition was lost, and the exchange event could not be found, and Lao Mei was disgusted with the objects he snatched from their country as prizes, and the mathematicians of the republic were very angry!

Many tourists have heard it, especially some young people, and their English is good.

"Sister!"

"It's so good!"

"Stink--what!"

"Whew!"

A lot of tourists are scolding on the periphery.

The young David looked at it, but he didn't understand what everyone was saying, squeezed out a handsome smile, waved at the crowd, and made a kiss gesture to a female tourist with high hip bones.

Everyone is even more angry!

Corner.

The little players of the republic are all together.

"Sister, don't cry. Huang Leilei saw that his sister was sad, and he was also in a sad mood, and he kept pulling his sister's arm by the side.

"Captain. ”

"Captain, I really don't blame you. ”

The other children have also been comforting her, Huang Lingling has been taking care of them like a big sister for the past six months, everyone likes her very much, and they don't want to see her uncomfortable.

But Huang Lingling is obviously a stubborn girl, she is the captain of the Republic team of this year's International Youth Mathematics Competition, and she is a representative selected from millions of students in thousands of middle schools, she not only represents herself, represents the school, but also represents the country this time, as the captain, she frequently makes mistakes in several key topics, which makes her regretful, and even thinks that it would be good if she didn't come to the competition, if someone else competed instead of herself, maybe their grades would be better, it was all her own fault, she lived up to the trust of the teachers and professors, looking at the professors who didn't pay attention to them at all, Huang Lingling's heart was screwed together, knowing that the teachers were completely disappointed in them.

Blame me!

It's all my fault!

Huang Lingling bit her lip and didn't speak, and suddenly, as soon as she raised her head, she looked at the question board of the U.S.-China team, her eyes became more and more determined, and she suddenly took steps and walked up.

Huang Leilei was stunned, "Sister, what are you going to do?"

Several other members of the squad also ran over to follow her, "Captain?"

Soon, everyone else also noticed Huang Lingling's strange behavior, and looked over for unknown reasons, no one knew what she was going to do.

Louis looked at the little girl strangely, "Huh?"

In the next second, Huang Lingling picked up the pen she used in the competition, gritted her teeth and stood in front of the American-Chinese-people question board, looking at the world math problem above, stubbornly took the pen and began to answer the question on a blank question board next to her, wrote a formula, she gritted her teeth, and clumsily wiped it off with her hand, and then wrote again, writing stopped, but it was a mess, with her level, of course, it was impossible to solve this kind of mathematical problem, let alone her, even if it was her teacher's teacher's teacher, she couldn't solve this problem!

Only then did everyone understand that the little girl wanted to solve the Dale conjecture, to make up for her mistakes in the game, for the sake of honor? or ...... For the sake of dignity?

At this moment, many tourists were impressed!

Including Zhang Ye, he also walked up and took a deep look at the stubborn girl.

Mathematicians and contestants from other countries all looked at it, some stunned, some speechless, and some laughed.

American-Chinese mathematician David shook his head again and again, muttering something in English that others couldn't understand, which was certainly not a good thing anyway.

An American-Chinese contestant glanced at Huang Lingling, "What is she doing?"

"I don't know. Another American-Chinese girl sneered: "The world's mathematicians have studied problems that they can't solve for decades, who does she think she is?"

"Joker!" said a young man.

The American-national team let out some laughter.

A young man on the British team said to her in English with a gentleman's kindness: "Don't write it, you can't solve it, you made a mistake in the previous game just carelessly, and it will be fine next time." ”

A French girl also said, "Yes, you are great." ”

But Huang Lingling didn't seem to hear it, she was still desperately calculating the problem, changing the picture, changing the picture.

Wu Zeqing sighed.

The tourists outside couldn't stand it either.

"Good boy, stop writing!"

"If you lose the game, you can't blame it all, it's not your responsibility!"

"Child, you are all the pride of the country, don't blame yourself, it's okay, it's really okay!"

Hearing everyone's words, Huang Lingling's eyes turned red again, and tears dripped into her mouth, but she didn't wipe them, and she was still struggling to calculate on the question board.

Huang Leilei clenched his fists and went up, "Sister, I'll help you!"

"And me!" a teenager from the Republic team also picked up a pen.

"Captain, and us! Let's count together!" The members of the team of the Republic have all stood beside Huang Lingling, some of them are only in their early tens, and some are less than one meter four tall, holding pens, and they have to tiptoe desperately to reach the question board in front of them.

In the face of this world's mathematical problem, they seem very small.
