Volume 1: Student Life Chapter 177 (3Xn+1)/2^m=1
After coming out of the library, Chen Zhou and Yang Yiyi were on their way back to the dormitory.
When the two of them reached the nameless lake, they stopped unconsciously.
Under the light, Wuming Lake has a unique scenery.
Chen Zhou tilted his head to look at Yang Yiyi and said softly, "Yiyi, shall we walk along the Wuming Lake for a while?"
Yang Yiyi nodded: "Okay."
Chen Zhou took Yang Yiyi's hand, and the two of them walked quietly along the shore of the nameless lake.
Objectively speaking, Yan University is not only one of the top universities in China, but its campus scenery can also be regarded as one of the most beautiful universities in China.
After all, there are many quaint buildings on the Yanda campus, and they also have certain historical significance.
Take Yanyuan for example. It was originally Shaoyuan in the Ming Dynasty and later became a royal garden in the Qing Dynasty.
Now it has become the campus of Yanda University.
The most famous place in Yanda is the nameless lake where Chen Zhou and his companions are strolling at the moment.
It is known as the "One Tower and One Lake" together with Yabo Tower and Yanda Library.
If you wait until the lotus flowers are in full bloom, the entire area around the Nameless Lake will be filled with fragrance.
In addition, the Yabot Tower on the shore rises high into the clouds and stands majestically, as if guarding the mountains and rivers.
The movement of Wuming Lake is matched with the stillness of Yabot Tower. The lake is moving while the tower is still. The lake is gentle while the tower is firm. The tower and the lake complement each other.
Chen Zhou pointed at the Yabota in the distance and asked softly, "Yiyi, do you know what this Yabota was originally used for?"
Yang Yiyi took a look at the Yabo Tower, which imitated the ancient Randeng Tower in appearance, and said with a smile: "Of course I know, it was originally used as a water supply tower."
Chen Zhou nodded slightly and asked, "Then do you know the meaning of Yabota and Wuming Lake?"
Yang Yiyi thought for a moment and replied, "Yabota means broad-mindedness, as for Wuming Lake, I don't know."
Chen Zhou stopped and looked at the Yabota in the distance, and said slowly: "Pray for erudition in front of the Yabota, and swear to be famous by the Nameless Lake. The meaning is to swear in the Nameless Lake to become a erudite person."
Yang Yiyi looked at Chen Zhou with a smile: "Okay, okay, I know you are a Chinese language genius."
"Hehe." Chen Zhou smiled embarrassedly.
Yang Yiyi glanced at Chen Zhou and asked softly, "Are you worried about something?"
Chen Zhou shook his head, then nodded, but said nothing.
Seeing this, Yang Yiyi asked softly, "About the project?"
"Yeah." Chen Zhou nodded. "In today's small class, Professor Zhang taught a math game. It was an inspiring lesson ."
Yang Yiyi asked: "What game?"
Chen Zhou: "Hail hypothesis."
As smart as Yang Yiyi is, she naturally understood what Chen Zhou meant.
She thought for a moment and said, "It's indeed difficult to take this as a research topic. But if you have made up your mind, why are you hesitating?"
Chen Zhou turned his head and looked at Yang Yiyi. He was indeed hesitant.
Although I made the decision to study the hail hypothesis, I also set a deadline for myself.
However, he was still somewhat afraid of this global problem.
The worst thing is to spend time and get nothing.
Chen Zhou admitted: "I don't know if I can complete this project."
Yang Yiyi held Chen Zhou's hand tightly and said softly, "It's not like you to hesitate like this. The person who dared to make a 725 agreement with all the teachers and students in the school and planned to graduate from both the Department of Mathematics and the Department of Physics in his freshman year should be a person who would not hesitate no matter what happens."
“We don’t know what the future will be like, but we can take every step today for the future. And the results of this project will only be known after we do it.”
"Most importantly, I trust your decision."
This was the first time Chen Zhou heard Yang Yiyi say so much. He saw complete belief in Yang Yiyi's eyes.
Chen Zhou smiled gently and rubbed Yang Yiyi's head with his other hand: "You are right, you should know after you do it. Instead of hesitating after you have made a decision."
"Yes." Yang Yiyi said with a smile, "Just like what you said just now, we seek Boya in front of Yabo Tower and become famous by the Wuming Lake. Aren't we..."
Before Yang Yiyi could finish her words, Chen Zhou suddenly exerted force on his hands and pulled her into his arms.
He hugged me tight.
Her hands also changed from being panic-stricken at the beginning to slowly resting on his body.
Chen Zhou whispered softly in Yang Yiyi's ear: "Thank you, Yiyi, it's great to have you."
Although Yang Yiyi didn't say anything, a smile appeared unconsciously on the corner of her mouth.
After a long time, the two separated.
Chen Zhou looked at Yang Yiyi's red face and couldn't help but joked, "Did you turn into a red apple?"
"Humph." Yang Yiyi snorted, "You are the red apple."
When Chen Zhou returned to the dormitory , it was almost 11 o'clock, which was much later than usual when he came back from the library.
As soon as they entered the dormitory, Zhao Qiqi and the other two looked at Chen Zhou.
Chen Zhou asked in confusion: "Why are you looking at me like that?"
The three of them said in unison: "Nothing, I thought you wouldn't be coming back tonight."
Chen Zhou was a little embarrassed: "If I don't come back, where will I sleep?"
Zhao Qiqi said: "I don't know then."
After a pause, Zhao Qiqi noticed something and whispered, "You smell like her perfume. It's my nose that's guilty..."
Chen Zhou: “…”
Zhu Mingli and Li Li were laughing secretly on the side.
Ignoring the three people, Chen Zhou picked up the washbasin and went to wash up.
"Fuck..."
While washing up, Chen Zhou realized why these three people were looking at him like that.
When he hugged Yang Yiyi, a strand of Yang Yiyi's hair fell on his clothes.
Still a very conspicuous location...
At night, Chen Zhou was lying on the bed, thinking of Yang Yiyi's words, and a smile unconsciously appeared on the corner of his mouth.
Chen Zhou also became more eager to solve the hail conjecture.
After sending a "good night" message to Yang Yiyi, Chen Zhou fell asleep.
In the following days, Chen Zhou studied the physics department textbooks according to the plan.
On the one hand, I spent a lot of time looking up topics related to the hail conjecture.
There was one discovery that surprised him, which was the algebra discussion class about Zhang Zhongyuan.
Some of the content discussed in class was recorded in the wrong question collection.
This also indirectly proves that the content discussed in that class was flawed.
Those that were not recorded also provided Chen Zhou with some references for the subject.
"Formulating the problem is necessary to solve the conjecture. Regarding the hailstone conjecture, or the 3X+1 conjecture, its formula is an iterative formula with input, output, and feedback..."
Chen Zhou first formulated the hail hypothesis and then conducted research on it.
【Xn＋1=（3Xn＋1）/2^m, where each X is an odd number, m=1, 2 , 3...】
[Until the even number 2^m in 3X+1 is extracted and canceled out, making the right side of the equation an odd number. If this odd number is not 1, but another odd number, continue iterating until it reaches 1. ]
[In other words, what needs to be proved is (3Xn＋1)/2^m=1]
