Chapter 93 Am I really not good enough?
101 Dormitory.
Looking at the blackened Xu Zhengyang, Xu Qingzhou could only say, you are really a damn talent. Thousands of words combined into one sentence: "Old Xu, take care of yourself."
Kong Xianbo and Zhai Ziqiang also expressed admiration.
I made up one day of classes on Sunday.
On September 30, Monday, the National Day holiday is about to begin.
Xu Qingzhou's afternoon class ended very early, but Song Yao didn't finish class until after 5 o'clock, so he could only go back to the dormitory and wait for her. After that, he went directly to the airport to meet Guo Ziyang and the others.
Tonight I will catch a flight back to Chengdu.
Xu Qingzhou originally felt that leaving at night was too urgent, but Guo Ziyang and others wanted to go back early. After all, it was their first time traveling far away and they missed home.
And daytime air tickets are not cheap during this time.
After discussion, everyone decided to buy a ticket at 20:30 in the evening.
"Brothers, see you at the beginning of school!" Xu Zhengyang's home is in Kyoto. After class, he packed his luggage and waved goodbye gracefully.
"See you when school starts." Zhai Ziqiang smiled.
Xu Zhengyang thought of something and stopped at the door: "By the way, I must be the first to come. I made an agreement in advance that no one without specialties will be allowed in."
Xu Qingzhou nodded: "First call dad to listen, and then I will bring it to you."
"My name here is Second Uncle." Kong Xianbo said.
Zhai Ziqiang scratched his head and looked at Xu Zhengyang shyly, "Then I will be the third uncle."
Xu Zhengyang: "."
Kong Xianbo and Zhai Ziqiang were leaving tomorrow, and they made an appointment to go to the library. Soon, Xu Qingzhou was the only one left in the dormitory.
He didn't waste time and moved forward according to the previously written plan.
Regarding Kramer's conjecture, there are currently two broad directions.
The first is to accurately understand the distribution of prime numbers through different sieving methods, such as Erberg's sieving method and Xia Guo's remainder theorem sieving method, and then find suitable mathematical tools to establish a mathematical model.
The second method is to use analytic number theory, first use mathematical analysis methods such as series and integrals to conduct in-depth research on the distribution rules and properties of prime numbers, and also use methods in statistical physics to study the aggregation and distribution patterns of prime numbers.
Among them, it is still necessary to construct an upper bound function on the prime interval through the ΞΆ function.
This is the same as the proof of the castration n times version some time ago, but the process is countless times more complicated.
Both of these methods will eventually require the use of the college's supercomputer to conduct large-scale prime number screening and improve the calculation and analysis capabilities of the distribution patterns of prime numbers.
6pm.
Xu Qingzhou came to the south gate to wait for Song Yao.
The things he brought were very simple, a hiking bag with two changes of clothes, and the rest was a computer and research manuscript.
At the school gate, there are all students pushing their suitcases to go home.
About 10 minutes later, a beautiful figure appeared in Xu Qingzhou's sight. She was wearing a white skirt today, looking like a pure female college student, pushing a huge suitcase that reached her waist.
Xu Qingzhou took the suitcase from Song Yao's hand, "Do 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 and dragged his suitcase to the subway entrance with Song Yao.
Passing by the security checkpoint, he picked up his suitcase and prepared to carry it onto the conveyor belt.
He exerted force on his hands and was stunned by the terrifying downward force coming from the suitcase.
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?"
As soon as he finished speaking, he saw Song Yao holding the handle with her left hand. She raised both hands and put the box on the conveyor belt. She raised her chin at him without changing her expression. The meaning was obvious: That's it?
Xu Qingzhou: "." On the subway.
Xu Qingzhou still couldn't figure it out. Could it be that he was really not good enough?
No, no, this woman Song Yao cannot be treated as an ordinary person, it must be her problem.
He exhaled and said quietly: "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. The fingers were white and slender and very beautiful. He squeezed it a few more times. It was soft and cold.
Song Yao pulled her hand back instantly as if she was electrocuted, 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 have mutated, otherwise why would you be so strong? Hiss~ Why are you pinching people again!"
At seven o'clock in the evening, they met Guo Ziyang and Ding Jiahui at the airport. Except for Xu Qingzhou, the other three people all dragged their suitcases.
Go through check-in procedures and check in luggage.
At 20:10 in the evening, Xu Qingzhou and four others had already boarded the plane.
Boeing's 747 has four seats in the middle. According to the tickets, they should be Guo Ziyang, Xu Qingzhou, Song Yao, and Ding Jiahui in this order.
Xu Qingzhou pointed to Ding Jiahui's spot on the far left and said, "Fat man, go and sit over there."
"Why?" Guo Ziyang didn't respond.
Xu Qingzhou said matter-of-factly: "Protect girls, of course we two big boys should sit in the aisle."
Ding Jiahui thought about it and thought it made sense. She didn't like sitting by the aisle. It was uncomfortable when people were coming and going, and she had to be bumped into from time to time.
So, Guo Ziyang gave Xu Qingzhou a look of thanks and successfully came to Ding Jiahui's side.
Song Yao sat down and spoke to Xu Qingzhou in a low voice: "You really just opened your mouth."
"Don't you think they are both very happy?" Xu Qingzhou spread his hands.
Song Yao curled her lips and thought to herself: Why haven't I seen you so considerate in normal times? You make me angry every day.
The night sky was clear and the stars were twinkling. The plane taxied on the runway and climbed slowly. The brilliant lights of the city on the ground quickly disappeared from sight.
After the plane's attitude stabilized, Xu Qingzhou laughed and quickly fell asleep.
Song Yao and Ding Jiahui were shopping on Taobao, discussing in low voices which clothes looked good.
When Xu Qingzhou woke up in a daze, he realized that his shoulders were a little heavy. Turning his head, he saw Song Yao sleeping soundly on her pillow.
Looking to the side, Ding Jiahui was also sleeping against Guo Ziyang.
Guo Ziyang couldn't sleep at all. He sat up straight and saw Xu Qingzhou looking at him, giggling all the time.
It's my first love.
At 11:30 p.m., the plane landed in Chengdu. As soon as he stepped out of the cabin, he felt the temperature rise sharply. Xu Qingzhou took off his coat and held it in his hands.
Song Yao pushed Ding Jiahui with her arm and said, "Jiahui, did you sleep well?"
"It's not because of you. We are obviously sisters. It's good for you, but you tilted your head and leaned on Xu Qingzhou's shoulder." Ding Jiahui didn't feel that there was anything wrong with her at all, and even complained.
"You are too thin to sleep comfortably." Song Yao pursed her lips.
Ding Jiahui looked like she had seen through it a long time ago and said, "I see you, you say no, but your body is very honest."
Song Yao said nothing and looked elsewhere.
Seeing Song Yao and Ding Jiahui lagging behind, Xu Qingzhou was a little helpless, "Are you two turtles? Go faster!"
Song Yao's father was on vacation today and said he was just coming to pick them up. He had been waiting at the airport gate half an hour ago.
