It was September soon, and in the last two days before school started, Su Qingyun went to the county and found her teacher Chu Xianming.
"Teacher." Su Qingyun placed the award certificate she received in front of Chu Xianming. She smiled mischievously, "I did it. Fortunately, I lived up to my fate."
Chu Xianming looked at the award certificate in front of him and smiled happily, "Well done, Qingyun."
She was able to win the first prize in the individual award. This result was what he expected and was not a surprise. However, Su Qingyun's perfect score still surprised Chu Xianming.
??"I heard that you were the only one to solve the last question in this written examination?" Chu Xianming asked her.
"right."
Su Qingyun glanced at the newspaper pressed under his glass plate. It was the page where she won the award. The teacher must have learned the question from it.
"Tell me, what is the question?" Chu Xianming was somewhat interested.
?"Assume that positive integers a and b satisfy ab+1 and can divide a2+b2, proving that (a2+b2)\/(ab+1) is a perfect square number." Su Qingyun directly repeated the question.
Chu Xianming quickly wrote it down in his notebook. After thinking for a while, he frowned and said, "Weida jumps."
"Yes." Su Qingyun nodded with a smile.
The teacher is indeed a teacher, and he soon discovered the key to solving the problem.
Chu Xianming: "It is indeed not easy, but you did a good job."
"Maybe it's because I have done more questions, so my thinking is more active than others." Su Qingyun smiled.
"Don't be too modest." Chu Xianming also smiled, "What about the free explanation session later? What topic did you draw?"
Although there are some reports in newspapers, they are not detailed enough to write out the title.
Su Qingyun paused, "It's the Riemann Hypothesis."
"Riemann Hypothesis?" Chu Xianming was stunned, with a rare expression on his face, "How could it be the Riemann Hypothesis?"
How is it possible to explain such a world-class mathematical conjecture within 10 minutes? Is that organizing committee crazy?
"All the test questions were randomly selected. Among so many participating team members, only one other team member and I got the world-class conjecture questions. He was Fermat's conjecture, and I was Riemann's conjecture. Maybe it was my luck. it's not good."
Su Qingyun explained the situation at that time in a few words.
"That's all, it can be considered a kind of fate." After Chu Xianming said this, he suddenly realized a question, "In other words, after you drew the Riemann Hypothesis, you still got full marks in this link?"
"Well, at that time the review team was more interested in some of my ideas on the Riemann Hypothesis, so they gave me high marks."
"What's your idea? Can you tell me?" Chu Xianming said impatiently, with a somewhat anxious expression.
"Okay." Su Qingyun nodded and began to speak slowly, "What I think is the Riemann Hypothesis is actually like this..."
There was no one in the library. The sunlight filtered in bits and pieces through the gaps between the leaves outside the window. The atmosphere in the library was very quiet, with only the low voices of teachers and students communicating.
I don't know how long it took, but Su Qingyun finally stopped talking, and Chu Xianming's expression was already a little dazed.
Although the things his student said were not very in-depth, he felt that this was indeed a very novel idea. If he continued to calculate further, no one knew what would happen next.
No wonder those on the review team would give her full marks. If it were him, he would do the same.
"Have you ever calculated these thoughts and ideas yourself? I mean, have you actually calculated the Riemann Hypothesis yourself?" Chu Xianming asked very seriously.
Su Qingyun paused, "No."
In fact, there was, but that was herself in the previous life. In this life, she was too busy, and indeed she had never calculated the Riemann Hypothesis by herself. If she hadn't been given this test question at that time, she had almost forgotten that she had been with this person. World-class mathematical conjectures are beyond comparison.
"You can do the math yourself." Chu Xianming encouraged her with a serious expression, "Maybe this is really a way."
Su Qingyun smiled and said, "How can it be so simple, teacher."
"If you don't do it, you will never know the result. You will know it only after you do it."
"I understand." Su Qingyun also looked serious and nodded.
In fact, when we were in Country E, during the night of discussion with everyone in the review team, they seriously told Su Qingyun that she should concentrate on studying the Riemann Hypothesis after returning to China. As long as she has some results, she can compile it into a paper. Everyone can help her check and make changes.
"I'll try to do it."
"That's good." Chu Xianming looked at the time and said, "It's almost there. That's it for today. You go back early."
"Okay, thank you teacher."
After Su Qingyun thanked her, she walked out of the library and got on the bus home. After arriving in the town, she unlocked her bicycle, but instead of going home, she walked in another direction. That direction was, the town. The direction of the government family home.
She went to find Ji Yue.
?When she arrived at the town government family home, Su Qingyun stopped her bicycle. When she was about to go in, she hesitated. At this time, she didn't know whether Uncle Ji, Aunt Ji, and the others were at home.
If they were there, it would be a little disturbing for her to go, and she would be left to eat by the enthusiastic Aunt Ji. If they were not there, it would be even worse. Although she thought it was okay, but if she was left by other people in the family home, Seeing that she and Ji Yue were alone at home, it was inevitable that they would gossip.
Su Qingyun thought for a while and stopped a child playing outside the family courtyard.
"Hey, kid."
The little boy, who was all dirty after rolling on the ground, blinked his big black eyes and looked at the beautiful elder sister who was pulling him in confusion, "What's the matter with you?"
Su Qingyun took out two milk candies from the bag and handed them to her, "Sister, I'll give you candies. Can you do me a favor?"
She thought that children of this age would agree to everything after seeing the candy. Unexpectedly, the little boy looked at her warily, "Why did you give me candy? Do you want to kidnap me?"
Su Qingyun: "..."
"Do I look like a kidnapper?" She had always suspected others of being kidnappers, and this was the first time Su Qingyun had been so suspected.
"Don't think that just because you're pretty, you don't look like a kidnapper." The boy still looked wary, "My mother said that the prettier a girl is, the better she is at lying. I won't fall into your trap. !”
Su Qingyun: "..." Is this a compliment to her? Or will it harm her?
Are all the children in this government family home so vigilant?
