Chapter 164 I suspect this guy is an alien! In the library, Xu Qingzhou spread out the draft paper and continued with the calculations he had just completed. For any r ≥ 3 (Nb, a) = 1, Np = "DI #(p:p< N, p= ba), (a, b)=1] Currently, he has found some information about the twin prime conjecture from a paper that shows that large even numbers can be expressed as the sum of a prime number and an almost prime number. Such as the double probability sieving method and Goldbach's conjecture (Yu Xinhe conjecture). The methods used in the reasoning process of Yu Xinhe's conjecture can also be tried on the twin prime conjecture. Zhang Yitang proved that there are infinite pairs of prime numbers (p, q), the difference between them does not exceed 7000 million. Later, in the "Poly-math8" project advocated by Terence Tao, the constant in the theorem continued to decrease and became 2 in February last year. However, a year later, this number has not improved. The fact that so many mathematicians have failed shows how difficult it is to prove the twin prime conjecture. However, this feeling of finding mathematical truth is indeed fascinating, no wonder so many mathematicians are crazy about it. 101 Dormitory.
Xu Zhengyang put his things away, put out his computer, logged into the game, and invited Kong Xianbo, "Old Kong, let's play the game!" This guy has been a playboy for half a semester, walking among the flowers but not picking a single leaf. He has given up completely this semester. What is a girlfriend? Can she have as much fun as playing games? Kong Xianbo shook his head. He was sorting out the materials for the first semester of his freshman year that he had received from his senior. He said in a muffled voice, "I want to read a book for a while." When I thought about the distance between me and Lao Xu every minute and every second, I felt like a stone was pressing on my heart. Xu Zhengyang turned around and saw Kong Xianbo was already preparing to go out. "Damn, he's already rolling around right after the school starts?" Okay, you guys go ahead and roll, I'll just indulge myself for a day first. Xu Zhengyang said in his heart. After the exams last semester, after more than ten days of anxiety, he decided to be more restrained. After all, there were 20 people who had to retake the mathematical analysis exam alone. If this continues, he will definitely be included in the reconstruction team that he despised last time. The most important thing is that during this year's New Year, the old man in the family has already said that if you fail the exam, he will break your legs. "Old Xu is working hard." Kong Xianbo sighed. Xu Zhengyang understood that this might be the despair of a top student being crushed by a genius student. Facing a pervert like Lao Xu, even he, a bad student, would feel a little bit of despair. Not to mention that Lao Kong has always regarded Lao Xu as a competitor. He sympathized with Kong Xianbo for a minute and advised: "Lao Kong, stop rolling. I have discovered a truth now - no matter how we roll, we can't avoid following Lao Xu and shouting 666." "." Kong Xianbo moved his throat and wanted to refute that only by knowing shame and then being brave enough could he catch up with Lao Xu's pace, but when he thought about it carefully, it was really true. What kind of quantum experiment is this? What kind of world-class problem is this? Can a serious person be so capable? Xu Zhengyang continued, "Isn't that right? Comparing with Old Xu is just asking for trouble. I even doubt if this old guy is an alien."
Kong Xianbo was very moved and felt that Xu Zhengyang expressed his true feelings. On this side, after Xu Zhengyang finished complaining, he saw that Kong Xianbo seemed a little shaken, and said lazily: "It's just reading, there's no need to rush for a day or two." "Besides, you worked so hard last semester and got first place in your major. Can't you enjoy yourself?" “I want to play Teemo.” Kong Xianbo was eventually dragged into the abyss of depravity by Xu Zhengyang. "Okay, come on, I'll build a room, and you can play whatever you want!" Xu Zhengyang was overjoyed. One of the happiest things during college was to drag his motivated roommate into decadence. In the Physics Department, Teacher Zhong Xiaodong, who came here to hand in materials, was stopped by Ji Yunshi. When they got closer, Ji Yunshi asked, "Xiao Zhong, how is classmate Xu Qingzhou doing?" "Everything is normal." Zhong Xiaodong said. "Oh? Have you ever encountered any instrument that you don't know how to use?" Ji Yunshi was surprised. Teacher Zhong Xiaodong smiled bitterly and said, "I've been there a few times, but Xu Qingzhou is quite familiar with those instruments." "This kid always brings me a lot of surprises." Ji Yunshi smiled gently, feeling much more relieved. He waved his hand and asked Zhong Xiaodong to go about his business first, thinking that maybe he could really get this kid to come up with something. This is actually a good thing. Some results can also shut up some people with conservative ideas and accuse them of approving projects indiscriminately and forcing things to grow. At 6 o'clock in the evening, Xu Qingzhou came to the optoelectronic laboratory again. After putting his things in the lounge, he went to the laboratory to take over from Ren Xiaoling. Hong Yayu and Gong Yunfei were both there, and Ren Xiaoling was also reading a book next to the laboratory table. "Senior Sister Hong, Senior Brother Gong." Xu Qingzhou greeted with a smile. Hong Yayu nodded indifferently as usual, which made Xu Qingzhou wonder if she had transferred all her expressions to the emoticon package on her phone. Gong Yunfei originally wanted to stand up and brag to Xu Qingzhou, but a look from Hong Yayu forced him back. He could only wave his hand and then immersed himself in the project calculations with a bitter look on his face. "Nothing unexpected, right?" Xu Qingzhou asked Ren Xiaoling. "It went very smoothly!" Ren Xiaoling shook her head. Hong Yayu praised: "Junior brother, your crystal is perfect." "Thank you, senior sister." Hong Yayu nodded slightly without saying anything else and continued to look at the information in her hand. Xu Qingzhou had already figured out this senior sister's personality, so he didn't try to find something to say. He said to Ren Xiaoling, "Senior sister, leave it to me. I'll start the crystal test at 9 o'clock tomorrow." "Make sure to be there on time!" Ren Xiaoling nodded excitedly. Xu Qingzhou sat down in Ren Xiaoling's seat just now and slowly flipped through the book "The Future of Lithium-ion Batteries" left by Wang Wei. At 10 o'clock in the evening, Hong Yayu and Gong Yunfei left, leaving Xu Qingzhou alone in the laboratory.
The surroundings are very quiet, with only the low humming sound when the equipment is running. Xu Qingzhou glanced at the crystal data on the screen. It was very stable. Judging from the situation, it would take about 3 hours. After checking the data, he walked out of the laboratory and called Song Yao on the balcony. The call was quickly connected, and a friendly girl's voice came, "Is the experiment over?" In addition to Song Yao's voice, one could faintly hear the whispers of girls, as well as Zhang Qiong's obvious reminder of "Speak softly, Xiaoyao is calling." "There are still about three hours left." Xu Qingzhou blew some hot air on his hands. Song Yao, wearing furry pajamas, lay on the balcony and whispered, "I can't go back to the dormitory tonight." "It's normal to do experiments." Song Yao was silent for a moment, and then reminded him, "It's quite cold at night, so be careful and don't get sick." In the dormitory, Zhang Qiong and two others stood together, looking at the girls on the balcony and gossiping in low voices. "What do you think, did they talk or not?" Zhang Qiong was depressed.
