The Science Fiction World of Xueba

I don't know how long, Pang Xuelin opened his eyes blankly, the first thing that caught his eyes was the white ceiling.

The moonlight shines through the windows. Compared with the softer artificial light source of the dungeon, the natural light in front of the eyes makes Pang Xuelin slightly unaccustomed to it, but it has a sense of intimacy.

Xu Pang Xuelin turned over and picked up the time on the nightstand, which was shown on November 6, 2019 at 19:30 in the evening.

Pang Xuelin remembers that he entered the wandering earth world at 00:00 on November 5, 2019. He spent 22 years in the wandering earth world, but the real world only passed 19 hours.

A moment of simmering flowers, the vicissitudes of the sea.

Xi Pang Xuelin has never felt this way, time is such a terrible existence.

I think of Yao Bingxia, Pang Xuelin's heart is still throbbing.

Although he knows that once he returns to the real world, sooner or later he will still part with Yao Bingxia, but at this moment, he is still a little unacceptable.

"I will never fall in love again in the Plane World!"

After a while, Pang Xuelin felt his stomach groaning for a while.

Although the system once said that after entering the plane world adventure, you can reduce your body metabolism and ensure nutrition supply.

But the food in the stomach will still be digested, and it will still be hungry.

Xi Pang Xuelin picked up his mobile phone, changed his clothes, and went out to find something to eat.

Tonight is a rare full moon night. The bright moon hangs high in the sky. The night wind blows the leaves and rustles. It's late autumn and there is a chill in the air, but Pang Xuelin feels a Unprecedented intimacy.

Recalling the world of wandering earth that has long been beyond recognition, this peaceful and peaceful world is the real golden age!

Xu Pang Xuelin stood at the entrance of the corridor, closed his eyes and enjoyed the beauty of the real world for a while. Suddenly, he was patted on the shoulder, and a crisp voice suddenly interrupted his thinking.

"Student, what are you doing here?"

Pu Pang Xuelin opened his eyes. A beautiful girl came into view, exquisite looks, well-shaped figure, and in his tone seemed to be familiar with himself.

Wu Pang Xuelin frowned. It seems that there is such a person in his memory, but he has spent more than 20 years in the wandering earth world. Many people in reality have long forgotten it. He had long lost his mind what the girl's name was.

"Oh, it's okay, I'm going out for a meal, let's go!"

Xi Pang Xuelin barely smiled, and then walked directly beside Qi Xin without saying a word.

咦 "Oh, what happened to this guy?"

Qi Qixin turned around and looked at Pang Xuelin's back with some confusion, always feeling that Pang Xuelin behaved strangely.

When I came to the restaurant, Pang Xuelin was almost blinded by the variety of food. The wandering earth world was in a state of scarce supplies. Even in Pang Xuelin's status, he didn't want to eat what he wanted.

Back to the real world is like returning to heaven.

Xi Pang Xuelin took a full two servings of various fruits and vegetables and it took half an hour to fill his stomach.

After eating, Pang Xuelin took another walk on campus.

As I walked along the road, from time to time I could see young students in trouble, couples whispering in the corner, night runners walking on foot, old professors walking leisurely ... life was comfortable and comfortable.

Pang Xuelin secretly sighed, what a wonderful time!

After walking around the campus for more than an hour, Pang Xuelin slowly sorted out her memories in the real world, familiarized herself with Jiangda's campus, and then returned to her residence.

Later, Pang Xuelin took out his mobile phone and first called his grandparents and his parents. For them, Pang Xuelin hadn't seen him for a few days, but for Pang Xuelin, he hadn't seen him for more than 20 years. Loved ones.

Then, Pang Xuelin began to find some people in his mobile phone address book who he didn't remember.

He didn't return to China for a long time, and there are not many people in the address book, but Pang Xuelin saw a lot of familiar names.

Pang Xuelin, who is a big man like Qiu Chengtong, Tao Zhexuan, Deligne, and Faltings, will not forget. These people are all added to the address book after the BSD conjecture report.

Liu Tingbo also had an impression, as if he was the president of Jiangda Mashu University.

Just who is this Qi Xin?

Pang Xuelin froze slightly, and the figure of that beautiful girl whom she had seen downstairs appeared in her head.

He pondered for a moment, turned out WeChat, opened the circle of friends, and really found Qi Xin's selfie in it.

Then Pang Xuelin entered Qi Xin's circle of friends according to this account, and accidentally found himself in a photo with her.

In the photo, Qi Xin stood in front of him, posing a cute scissors hand, while standing behind him, smiling awkwardly.

The essay is: On the first day of returning to school, I met Professor Pang Xuelin, the legendary learning god, hehe, he was more approachable than I thought. Today, thanks to his help, he carried my 100-pound box to the eighth floor, otherwise I am tragedy.

Wu Chenfeng's memories were slowly awakened, and everything about Qi Xin reappeared in Pang Xuelin's mind.

"It seems that my relationship with her is a bit ambiguous, but I did not break through the last layer of window paper ..."

A faint nostalgia and sadness appeared on the face of Xun Pang Xuelin.

Xu and Yao Bingxia experienced that sad relationship in the stray earth world ~ www.readwn.com ~ Pang Xuelin did not think of falling in love for a short time.

"How do you get along with her next?"

"Forget it, don't want so much, take a step and count it!"

Uh ...

Xi Pang Xuelin shook his head, put down the phone, and began to think about the next work plan.

Now, only by devoting myself to work, can I suppress the guilt and pain of Yao Bingxia in my heart.

In the wandering earth world, he completed the construction of Ponzi's geometric theory system by himself, and used this theory to give the general solution of the system of nonlinear partial differential equations in the general sense.

的 The exact solutions of nonlinear partial differential equations are aimed at the numerical solutions of such equations. The general solution is to obtain the solution form of the equation by some methods. After giving the specific initial boundary value conditions, the special solution is obtained.

However, at present, only simple hyperbolic, elliptic and other equations can get the general solution and special solution.

Most of the nonlinear partial differential equations can't get accurate solutions at all, so for Ponzi geometry, the nonlinear partial differential equations are like the group theory of the year when solving the equations.

But in the field of number theory, the value of Ponzi geometry has not yet been developed.

I know that I had come up with Ponzi geometry theory in order to solve the ABC conjecture. Who thought that in the wandering earth world, this theory unexpectedly played an unexpected role in solving nonlinear partial differential equations.

In the past few years, my main work in the stray earth world has been on the scientific committee, and I don't have time to think about the ABC conjecture.

Now, it's time to consider solving this problem.

Xi Pang Xuelin thought for a moment, pulled out the manuscript paper, and went back to work.
