Chapter 154: Click me?
Yes, Xu Qingzhou is ready to strengthen his study in the field of number theory.
Number theory is a theory that studies the properties of integers. The basic element of integers is prime numbers. Therefore, it can be said that the essence of number theory is the study of the properties of prime numbers. To study prime numbers, we cannot do without various conjectures about prime numbers.
Krammell's conjecture is one, no, it should be called Krammell's law now.
In addition, there are Goldbach's conjecture and Fermat's last theorem among the world's three major mathematical conjectures, as well as the Riemann hypothesis among the seven major problems of the millennium.
These are top-level mathematical conjectures, each of which is hellishly difficult.
Xu Qingzhou is not that stubborn yet. In his opinion, solving mathematical conjectures is like fighting monsters and leveling up. If you act like the ultimate boss, you will die without even a scumbag left.
Solving these top-level conjectures is a matter for math enthusiasts among the people.
This is no joke. Folk scientists really have no interest in the mathematical problems of the third and fourth steps. They only study Goldbach's conjecture, the four-color conjecture, and the like. Some even want to disprove what has been proved. Fermat's last theorem.
Even if Xu Qingzhou had these things in his possession, he still wouldn't dare to think about them.
Turning on the computer, there was the paper he read before going to bed last night, "Bounded Distances Between Prime Numbers" by Zhang Yitang, which was a paper on twin primes published in the "Annals of Mathematics" in 2013.
Yes, let’s ignore the speculation about the difficulty of hell for the time being. To Xu Qingzhou, these things are like castles in the air that can be seen but cannot be grasped.
In the third echelon, you can try the twin prime conjecture.
Twin prime numbers refer to pairs of prime numbers that differ by 2, such as 3 and 5, 5 and 7, 11 and 13..., which can be described as follows: there are infinitely many prime numbers p, such that p+2 is a prime number.
This paper proves the weakening situation of the twin prime conjecture, that is, it is discovered that there are infinite pairs of prime numbers with a difference less than 70 million. This is the first time that someone has proved that there are infinite pairs of prime numbers with a distance smaller than a certain value.
70 million and 2 may seem far apart, but for analytical number theory, it is the difference between 0 and 1. Something comes from nothing, or in other words, it allows mathematicians to change from finding a needle in a haystack to finding a needle in a pond, or even Find a needle out of a swimming pool, find a needle out of a bowl.
Taking a deep breath, Xu Qingzhou took out his notebook and began to sort out the information he had seen recently.
At first glance, it seems very difficult.
Xu Qingzhou stayed at home like this for a day. In the afternoon of the next day, he received a call from Guo Ziyang, asking him to go online together. Xu Qingzhou refused. Playing games was no fun.
However, after thinking about it, he had to stay at home and was told by Ms. Wang, so he just went to ask Guo Ziyang what he thought, so he asked Guo Ziyang if he wanted to go out to dinner and treat him.
After hearing Xu Qingzhou's offer of a treat, Guo Ziyang agreed without even thinking.
Xu Qingzhou said hello to Ms. Wang and was about to go out when he received another message from Song Yao.
Song Yao: "I heard that a snack street has opened in Xueyuan Street. Can we go together in the evening?"
Xu Qingzhou typed: "Not today, I have to go find Guo Ziyang to talk about Ding Jiahui."
Song Yao: "Okay, let him be brave and act like a man."
Xu Qingzhou looked at the message from Song Yao with a strange expression, why did he feel like he was being targeted.
Phew~
I must be thinking too much.
After speaking silently, he put away his phone and went out.
At 5:30 in the afternoon, Xu Qingzhou saw Guo Ziyang at the intersection. Compared with the last time they met, this guy seemed to be much more mature. At least he didn't look so naive. This made Xu Qingzhou smack his lips. Love can really make people grow.
Just when he was sighing with emotion, Guo Ziyang's expression changed and he took his hand, "Zhouzi, hurry up, let me get the aura of the god of learning."
Saying that, he even hugged her.
"Go, go, I don't want to be gay." Xu Qingzhou quickly backed away, disgusted.
Guo Ziyang's eyes were full of resentment, and he walked towards the street with Xu Qingzhou. After walking for a while, he came over again and asked expectantly: "Zhouzi, what kind of dinner are we having?"
"We're here." Xu Qingzhou stopped at the door of a noodle shop.
"Noodles?" Guo Ziyang's mouth twitched.
Xu Qingzhou walked in first, "Forget it if you don't want to eat." "Eat!"
In the noodle shop, the two of them ordered a bowl of noodles each and then sat and chatted.
Guo Ziyang asked curiously: "Did you stay at home all day yesterday?"
"Well, I plan to study number theory." Xu Qingzhou nodded.
"Awesome." Guo Ziyang gave a thumbs up. He used to be envious and jealous, but now he is completely open.
Xu Qingzhou said: "It goes without saying that we all know things."
Guo Ziyang complained in his heart, Zhouzi felt even worse after not seeing him for a while.
Xu Qingzhou glanced at Guo Ziyang opposite and asked about business: "You really don't like Ding Jiahui?"
Guo Ziyang scratched his head and said sheepishly: "I like it, but I feel a little embarrassed."
"It's embarrassing." Xu Qingzhou rolled his eyes and complained: "Isn't it just a failure to express my love? If you get divorced in the future, you won't be able to live a good life."
Guo Ziyang: "Damn, Zhouzi, don't curse me!"
Xu Qingzhou curled his lips and said in his heart that if you continue like this, I'm really not cursing you, I'm just giving you a warning in advance.
"Give it a few more days, I'll still feel weird seeing her." Guo Ziyang sighed.
Xu Qingzhou smiled and said: "Ding Jiahui likes you. At this time, you just need to work harder."
"Really?" Guo Ziyang was doubtful. The last time they came back together, Ding Jiahui basically didn't talk to him. She obviously wanted to keep a distance.
"Yes, Song Yao said it herself."
After saying this, Xu Qingzhou stopped. His own cement seal was loosened, and he was still here as a dog-headed strategist.
"Xu Qingzhou, Guo Ziyang."
At this time, a voice sounded.
Xu Qingzhou turned around and saw a beautifully dressed girl standing behind them.
Looking at Tian Shuang, Guo Ziyang was surprised: "Are you really here?"
Xu Qingzhou looked at Guo Ziyang questioningly.
Guo Ziyang explained: "She asked us what we were doing just now, and I said we were going to Nanlin Road to eat noodles."
"I just happened to come here to buy something, but I didn't expect you to be here."
With that said, Tian Shuang sat down on the stool next to Xu Qingzhou, raised her hand to brush her hair, and said, "Classmate Xu Qingzhou, I won't even tell my old classmates when I return to Chengdu."
Tian Shuang is dressed very delicately and has a naughty touch when she behaves and speaks, making it easy for people to get close to her.
"I just got back too." Xu Qingzhou smiled lightly, haha, just right, how can there be so many just right.
Girls like Tian Shuang are beautiful, active, and generous. Many boys can't resist such girls.
Moreover, her family is pretty good and rich, which makes her better dressed than most girls of the same age. For example, at the last high school reunion, many girls were in the middle of high school and college in terms of dressing and makeup. stage, looks weird.
Tian Shuangzhen came to Xu Qingzhou with a very clear purpose, to establish a relationship. Since she knows so many boys, only an outstanding boy like Xu Qingzhou can become her boyfriend.
But Xu Qingzhou can't get enough food and salt.
