Chapter 172: no problem
Chapter 172 No problem
Xu Heng looked uneasy when he returned home. His wife Zhang Shuqin saw it and wondered, "What's wrong with you? Did something go wrong with your recent project?"
Zhang Shuqin is also a professor at Lanzhou University, teaching history.
"Nothing." Xu Heng said vaguely, "I'm going to the capital tomorrow."
“What are you going to the capital for?”
“Go and see the teacher.” Xu Heng said as he walked into the room. He had to put things away.
Zhang Shuqin was surprised. It wasn't a New Year or a holiday, nor was it his teacher's birthday. Why was he going to see him? And isn't he very busy recently? Still have time to run to the capital?
Early on the next morning, Xu Heng, who had barely slept all night, took the earliest flight to the capital. He was so immersed in emotion that he almost forgot to call the teacher and almost missed it.
“Xiao Xu, why are you here?” Fang Ruxin’s wife, Ms. Li Yu, was a kind old lady. She looked at her husband’s student who appeared at the door of her home in surprise in the early morning.
Xu Heng smiled with a smile on his face, "Hello, Mrs., is the teacher here?"
“Come in.” A strong voice came from inside.
Fang Ruxin is over sixty this year. He has a strong body and only half white hair. He is used to getting up every morning to practice two calligraphy writings.
"That's right." Xu Heng nodded, trying to calm down, "This is the manuscript of the entire process of proving the Riemann hypothesis."
“Okay.” Xu Heng sat down as instructed.
At this moment, he had just put down his pen and blew out the wet ink. The words on the rice paper were flying and dancing, quite elegant. If he had put it down normally, Xu Heng would definitely praise it, but now he has no such intention at all.
“Teacher, I came here today to show you something.”
“Thank you, Master.”
Xu Heng quickly thanked him, and Li Yu took him to the door and went out.
“It has not been completely determined, but judging from the half that has been verified, there is nothing wrong.” Xu Heng used accent on the last four words.
"Oh? What is it? You have to travel all the way to deliver it here?" Fang Ruxin became interested, "Let's make a deal first. If you are here to give me a gift, there is no need."
When she was studying, several students often came to her house for food. She remembered the taste of her husband’s students.
But after just a few glances, he almost accidentally knocked over the scalding tea. He hurriedly put the tea away. It didn't matter that he was burned, but he couldn't get it wet.
Xu Heng remained silent, not daring to disturb the teacher.
"Tell me, what happened?" Fang Ruxin glanced at him who was about to speak but hesitated.
"Let me take a good look." Fang Ruxin's face was horribly serious. He took out his reading glasses and read every word, while his hands were moving quickly to calculate.
Fang Ruxin took it and saw that the cover was just an ordinary draft, but he knew that something that could attract Xu Heng's attention must not be simple, so he turned to the first page.
Xu Heng unzipped the bag that was tightly covered all the way and took out the contents. "Teacher, I want to ask you to take a look at this."
Li Yu served two cups of hot tea, "You guys chat first, I'll go buy groceries and make you the squirrel mandarin fish you like for lunch."
Early this morning, this student who had not been visiting for a long time suddenly called and said that he would come to visit today. I was afraid that he would go to the Three Treasures Hall for nothing.
Fang Ruxin: "Are you sure? Have you verified it?"
"This is..." Fang Ruxin's facial muscles trembled in disbelief.
“Sit down first and speak slowly.”
"of course not."
After a long time, Fang Ruxin took off his glasses and rubbed his sore eyes. After all, he was old and would feel tired if he looked at things for a long time.
But his eyes shone astonishingly, and he was obviously very excited. "I haven't found any problems yet. His thinking is very special."
Over the years, many people have challenged to prove the Riemann Hypothesis and have imagined many ideas and methods, but none of them have been successfully demonstrated. The ideas in this manuscript are completely different from those of the predecessors. Even if the proof is incorrect, it can still be proved. To put it bluntly, this author is an absolute genius.
“Give me a few more days and I’ll take a good look and verify it.” Fang Ruxin knew that this manuscript was of great significance.
"Okay, teacher, that's what I mean." Xu Heng nodded quickly, that was exactly what he came for.
Fang Ruxin pondered for a moment and asked him: "Can you tell me who the author of this manuscript is?"
The handwriting of the manuscript was obviously not Xu Heng's, and Fang Ruxin never thought it was his. Although this student was quite talented, he was still far from the manuscript.
But since such an important thing was sent by him, then this person must have a close relationship with him.
Xu Heng hesitated and then told the truth, "He is a student of Qi Fang."
“Qi Fang?” Fang Ruxin was stunned when he suddenly heard the name and ignored the last three words.
Qi Fang can be said to be the most talented student in mathematics he has ever encountered in his educational career. But in the end he did not choose to pursue the path of mathematics research and went to teach in some middle school, wasting his talent in vain.
Of course, he didn't mean that there was anything wrong with teaching and educating people. He was also a teacher, but he still felt pity for Li Qifang. He could have achieved higher achievements.
Fang Ruxin sighed, "That kid Qi Fang has been thinking that I am angry with him all these years, and he feels ashamed of my teachings to him. He has not even dared to come to the door for so many years."
“He has been thinking about you, otherwise he wouldn’t have let me come to you with this.” At this time, Xu Heng still put in a good word for Lao Li.
"Humph, thinking about me?" Fang Ruxin snorted, "Why doesn't he come by himself when he's thinking about me?" "Don't he have to teach students?"
“Class?” Fang Ruxin suddenly paused. What did Xu Heng say to Qi Fang just now?
“Who did you say the author of the manuscript was from Qifang?”
“It’s his student.” Xu Heng didn’t know whether to laugh or cry. He asked why the teacher was so calm. He didn’t hear clearly at all.
"Student?" Fang Ruxin was stunned, "Isn't Qi Fang teaching high school? When did he go to teach at the university?"
Even if it is a university, this is not possible, right?
Although he didn’t know who the author of the manuscript was, he could tell from between the lines that the author had profound mathematical accumulation. That kind of accumulation would be impossible without decades of accumulation. How could it be a young student?
"No, Qi Fangta teaches high school." Xu Heng shook his head and denied his teacher's thoughts. To be honest, if he hadn't seen it with his own eyes, he wouldn't have believed it.
“High school? High school!” Fang Ruxin lost her composure, “How is that possible?”
“Impossible!” he muttered.
"I saw it with my own eyes. It seems that the birth of this manuscript has something to do with me." Xu Heng told him the whole story, regardless of whether his teacher's heart could bear it.
“You mean, a high school girl proved the Riemann Hypothesis in five days.” Fang Ruxin said in a calm tone. When a person is extremely surprised and shocked, he will calm down.
Xu Heng nodded, "Yes."
Fang Ruxin looked at the bright sun shining outside the window, listening to the real chirping of cicadas, and shook her head with a sigh, "If this manuscript hadn't been placed here, I would have thought you were making up stories to make me happy. "
Xu Heng smiled bitterly, "Don't talk about you, I still feel like I'm dreaming."
Why doesn’t Fang Ruxin think so? If Xu Henggang said what he said, others would definitely regard him as a lunatic. It is really unbelievable!
"There are talented people from generation to generation. We are lucky to have such talents in our country!" Scholars like Fang Ruxin who have come from the turbulent times want to see the emergence of such talents most. Let them have successors and the country prosper.
Fang Ruxin: "You really gave me a big gift. By the way, what's the name of the child?"
"Yunsu, the cloud of flowing clouds, the su of Fusu."
“Good name.” Aiwujiwu, Yunsu’s clear words can be praised by him. ,
However, Fang Ruxin frowned, "Why does this name sound familiar?"
Xu Heng: "You may have seen her on the news before. She won the gold medal at IMO some time ago, and she was the only one with a perfect score."
Fang Ruxin usually pays close attention to the news in the mathematics world. It is normal to have seen Yunsu on TV. When Xu Heng said this, he remembered it.
“Is she the girl who spoke at London University?” Fang Ruxin remembered clearly that she had praised this girl for making the Chinese people proud.
“Yes, that’s her.” Xu Heng nodded.
“Qi Fang does have a good student.” Fang Ruxin sighed.
“Yeah, I’m so jealous.”
“Hahaha.” Fang Ruxin laughed heartily.
"You two haven't finished talking yet? Wash your hands and eat quickly." Li Yu interrupted the conversation between the teacher and the student.
“Okay, come on, let’s go, eat, and see if your wife’s craftsmanship has deteriorated.”
“That’s definitely not the case.” Xu Heng stood up.
Li Yu is a typical Jiangnan person. His specialty is Subang cuisine, and squirrel mandarin fish is one of the classic dishes.
Using mandarin fish as the raw material, it is deboned, cut into pieces, and fried to take on the shape of a squirrel. After the shape is set, it is poured with sweet and sour marinade. It tastes fresh, sweet, crispy, and tender, and you won’t get tired of eating it.
“Come, have a try.” Li Yu gave him a chopstick.
“Thank you, Master.” Xu Heng took a bite and praised, “It’s delicious, it still tastes like this.”
“I’ll come here more often after it’s delicious. Your teacher and I are retired now and have a free day. I’m looking forward to having you come over to make the house more lively.”
“That’s because you have time, but I don’t.” Fang Ruxin retorted.
Xu Heng smiled and agreed, "Okay, I will definitely bother you more in the future, as long as you and the teacher don't find me annoying."
"Look at what you are saying, eat quickly, the food will get cold later." Li Yu said angrily.
They had a pleasant lunch. Neither the teacher nor the student mentioned what had just happened at the dinner table. They understood each other tacitly. Before it was confirmed, the less people knew about it, the better.
"Then I'll take my leave first. Teacher and mistress, please take care of yourself." Xu Heng said goodbye.
"Okay, be careful on the road." Fang Ruxin knew that he was also very busy. "Go back and ask Qi Fang to call me. I will ask you carefully. If I have any results, I will inform you."
“Sorry to trouble you.”
