Chapter 93 Am I really not capable of this?
101 Dormitory.
Looking at the darkened Xu Zhengyang, Xu Qingzhou could only say, "You are really a talented person." Thousands of words can be summed up in one sentence: "Old Xu, take care of yourself."
Kong Xianbo and Zhai Ziqiang also showed expressions of admiration.
I made up a day of classes on Sunday.
On Monday, September 9, the National Day holiday is about to begin.
Xu Qingzhou's afternoon class ended very early, but Song Yao's get out of class didn't finish until after 5 o'clock, so he had to go back to the dormitory to wait for her. After the class, he went directly to the airport to meet up with Guo Ziyang and the others.
I will catch a flight back to Chengdu tonight.
Xu Qingzhou originally thought it was too early to leave at night, but Guo Ziyang and the others wanted to go back early. After all, it was their first time traveling far away and they missed home.
And the daytime air tickets during this period are not cheap.
After discussion, everyone decided to buy tickets for 20:30 in the evening.
"Brothers, see you at the start of school!" Xu Zhengyang's home is in Kyoto. After class, he packed his luggage and waved goodbye in a cool manner.
"See you at the start of school." Zhai Ziqiang smiled.
Xu Zhengyang thought of something and stopped at the door: "By the way, I must be the first one to arrive. Let me make it clear that those who don't bring any local specialties will not be allowed in."
Xu Qingzhou nodded: "Call dad first and come to listen, and I will bring it to you."
"In my case, you can call me Second Uncle," said Kong Xianbo.
Zhai Ziqiang scratched his head and looked at Xu Zhengyang shyly, "Then I am the third uncle."
Xu Zhengyang: “.”
Kong Xianbo and Zhai Ziqiang are leaving tomorrow. They made an appointment to go to the library. Soon, Xu Qingzhou is the only one left in the dormitory.
He didn't waste time and proceeded according to the plan he had written previously.
There are currently two major directions regarding Cramer's conjecture.
The first one is to use different sieve methods, such as the Sieve of Gilberg and the Sieve of Xia's Remainder Theorem, to accurately understand the distribution of prime numbers, and then find suitable mathematical tools to establish a mathematical model.
The second method is to use analytic number theory, which first uses mathematical analysis methods such as series and integrals to conduct in-depth research on the distribution laws and properties of prime numbers, and also uses methods in statistical physics to study the clustering and distribution patterns of prime numbers.
Among them, it is still necessary to construct an upper bound function about the prime number interval through the ζ function.
This is similar to the proof of the version that was castrated n times some time ago, except that the process is countless times more complicated.
Both of these methods ultimately require the use of the college's supercomputers to conduct large-scale prime number screening and improve the ability to calculate and analyze the distribution patterns of prime numbers.
6 pm.
Xu Qingzhou came to the South Gate to wait for Song Yao.
The things he brought were simple: a mountaineering bag with two sets of clothes, and the rest were a computer and research manuscripts.
The school gate was full of students pushing their suitcases and preparing to go home.
About 10 minutes later, a beautiful figure appeared in Xu Qingzhou's sight. She was wearing a white skirt, looking like a pure college girl, and was pushing a huge suitcase that reached her waist.
Xu Qingzhou took the suitcase from Song Yao and asked, "You need to bring so many things in 7 days?"
"I just brought some clothes and cosmetics." Song Yao said.
Xu Qingzhou shook his head, dragged his suitcase and went to the subway entrance with Song Yao.
Passing the security checkpoint, he picked up his suitcase and prepared to lift it onto the conveyor belt.
He exerted force with his hands, and the terrifying downward force from the suitcase made him stunned.
Not moving at all?
Xu Qingzhou's mouth twitched, and he turned to look at Song Yao: "Did you stuff all the beds in the dormitory in there?"
Just after he finished speaking, he saw Song Yao grab the handle with his left hand, raised both hands, and put the box on the conveyor belt. Without changing his expression, he raised his chin at him, and his meaning was very clear: That's it?
Xu Qingzhou: “.” On the subway.
Xu Qingzhou still couldn't figure it out. Was it really him who was not capable enough?
No, no, Song Yao is a woman who cannot be treated as an ordinary person. It must be her problem.
He exhaled and said faintly, "Show me your hands."
Song Yao didn't understand what he wanted to do, but she still stretched out her left hand.
Xu Qingzhou grabbed Song Yao's hand and looked at it. Her fingers were white and slender, very beautiful. He pinched them a few more times. They were soft and icy cold.
Song Yao pulled her hand back instantly as if she had received an electric shock, and glared at him angrily: "Xu Qingzhou, if you want to take advantage of me, just say so."
"Who wants to take advantage of you? I just wonder if you've mutated, otherwise why do you have so much strength? Hiss~ Why are you pinching me again!"
At seven o'clock in the evening, the two met Guo Ziyang, Ding Jiahui and others at the airport. Except for Xu Qingzhou, the other three were dragging suitcases.
Check-in and baggage check-in.
At 20:10 in the evening, Xu Qingzhou and four others had boarded the plane.
It was a Boeing 747 with four seats in the middle. According to their tickets, the order of seats should be Guo Ziyang, Xu Qingzhou, Song Yao, and Ding Jiahui.
Xu Qingzhou pointed to the leftmost seat where Ding Jiahui used to sit and said, "Fatty, go sit over there."
"Why?" Guo Ziyang didn't react.
Xu Qingzhou said seriously: "To protect the girls, we two grown men should of course sit in the aisle."
Ding Jiahui thought about it and felt that it made sense. She also didn't like sitting by the aisle because it was very uncomfortable with people coming and going and she would be bumped by people from time to time.
So, Guo Ziyang gave Xu Qingzhou a look of gratitude and successfully came to Ding Jiahui's side.
Song Yao sat down and spoke to Xu Qingzhou in a low voice: "You really speak without thinking."
"Look, aren't they both very happy?" Xu Qingzhou spread his hands.
Song Yao curled her lips and thought to herself, why haven't I seen you be so considerate before? You make me angry every day.
The night sky was clear and the stars were shining. The plane taxied on the runway and slowly climbed. The brilliant lights of the city on the ground soon disappeared from sight.
After the plane's attitude stabilized, Xu Qingzhou laughed and soon fell sleepy.
Song Yao and Ding Jiahui were browsing Taobao and discussing in low voices which clothes looked good.
When Xu Qingzhou woke up from his sleep, he found that his shoulder felt heavy. He turned around and saw Song Yao sleeping soundly with her head resting on it.
Looking to the side, Ding Jiahui was also sleeping next to Guo Ziyang.
Guo Ziyang couldn't sleep at all. He sat straight and saw Xu Qingzhou looking at him, and he kept grinning foolishly.
It's the first time for love.
At 11: in the evening, the plane landed in Chengdu. As soon as he got out of the cabin, he felt the temperature suddenly rise. Xu Qingzhou took off his coat and held it in his hand.
Song Yao nudged Ding Jiahui with her arm and said, "Jiahui, did you sleep well?"
"It's all because of you. We are sisters, but you tilted your head and leaned on Xu Qingzhou's shoulder." Ding Jiahui didn't think there was anything wrong with her and even complained.
"You're too thin. It's uncomfortable to sleep." Song Yao pursed her lips.
Ding Jiahui had an expression that showed she had seen through everything and said, "Look at you. You said no, but your body was very honest."
Song Yao said nothing and looked elsewhere.
Seeing Song Yao and Ding Jiahui falling behind, Xu Qingzhou was somewhat helpless, "You two are like turtles, hurry up!"
Song Yao's father is on vacation today and said he was here to pick them up. He had been waiting at the airport gate half an hour ago.
