However, Liu Shiyuan did not go to a press conference this time, this time he was interviewed by the Arowana video website.

This is his own website, so naturally he needs a lot of care.

Because the boss is coming, many people are busy, they all know that it is not easy for Liu Shiyuan to come once, if he can't satisfy him, he may withdraw this website, if he is satisfied, maybe he can inject funds again.

"Move for me, all the hosts come to me, don't talk to me about what is off duty today, do you know what day it is? Today is the day when the boss comes, you must work hard, do your best, keep improving, and let the boss know that our team is a very close team. The director is also saying.

"And today's program is arranged for you to be proficient, the first thing to do is for the three of you to go into battle at the same time, but I remind you of one thing, not only to let the boss see that there is a beautiful woman in front of him, but also not to rob the lens of our protagonist today, who is the boss.

I'm sure you can do that, and that's the question you're going to ask today, because our boss colleague is also a mathematician, and he's going to do a really great thing today.

Announce his conjecture. ”

"Attention, everyone, the boss is here." I don't know who said that, but many people have entered the state of work. Even if you don't have a job in hand, find something to do.

"Boss, you are here, I am Guo Feiyu, the director of Arowana Video, and I will be in charge of all your matters next." Guo Feiyu said with a smile, and the tension could be heard between the words.

"Don't be nervous, it's not a big deal. It's good to have a normal heart. Let's not talk nonsense either, let's start now. Liu Shiyuan said with a smile.

Guo Feiyu led Liu Shiyuan to the studio.

A lot of people and three beautiful hosts are already in place.

The lively and lovely Zhao Bingbing said: "Thank you for your support for Arowana Video, the guest we invited today is Liu Shiyuan, who is also the real boss of our Arowana Video." ”

Niu Yayan, a spicy girl with a big grin, said: "Yes." I was a little nervous because I met our real boss. ”

In the end, I thought it was Xie Xiuqiao and said: "Then I will talk to you about Liu Shiyuan's back today, and the most important thing is that Liu Shiyuan is naturally going to announce a mathematical conjecture today, which is also our main purpose today, and I will ask our boss Liu Shiyuan to answer his conjecture for us." ”

Each of the three beauties has its own unique beauty.

And Cui Wenxu didn't want to let much.

Liu Shiyuan walked in step by step and said: "Thank you for meeting you here, today is of course to announce a mathematical conjecture for you." If someone can solve this conjecture, I, Arowana, will pay a million dollars in bonuses. ”

The people below were shocked. Suddenly, many people became very interested in this issue.

"I really don't know what topic Liu Shiyuan is going to come up with this time, do you know? The last time Liu Shiyuan solved the problem, it was a conjecture in the mathematical world, and you must know that this conjecture has stumped a large number of people. But it was solved by the people of Huaxia. This is definitely a thing that gives us a very long face in Huaxia. ”

"Who's to say it isn't? I heard that many people say that it is a pity that Liu Shiyuan's talent is not to be a mathematician. ”

"You haven't seen a foreign scientist, no matter how you say that he uses it, I believe that if this conjecture is correct, it will definitely alarm many people."

"Needless to say? Liu Shiyuan is also too talented, the more talented people are, the richer they are. Let's not say anything. ”

Many people listened attentively to the question that Liu Shiyuan was about to say.

"Any single connected. A closed three-dimensional manifold must be homogeneous to a three-dimensional sphere.

To put it simply, a closed three-dimensional manifold is a three-dimensional space without boundaries; Single connectivity means that every closed curve in this space can be continuously contracted into a point, or in a closed three-dimensional space, if each closed curve can be contracted into a point, this space must be a three-dimensional sphere. ”

Seeing that everyone was confused, Liu Shiyuan knew that many people did not understand these questions.

He continued: "If you think this statement is too abstract, let's imagine this:

We imagine such a house, this space is a ball. Or, imagine a giant soccer ball. It was filled with gas, and we drilled inside. We might as well assume that the walls of this spherical house are made of steel. Very sturdy, no windows, no doors, we were in such a spherical house. Take a balloon and bring it to this spherical house.

Any balloon can be used (in fact, there are requirements for this balloon).

This balloon is not deflated, but has been blown into a certain shape, any shape can be (there are certain requirements for the shape).

But this balloon. We can also continue to blow it up, and assuming that the skin of the balloon is particularly strong, it will certainly not be blown up. It is also assumed that the skin of this balloon is infinitely thin.

Okay, so let's go ahead and blow up the balloon. Blow all the time. What happens at the end of the blow? Monsieur Poincaré guessed that the surface of the balloon must have been tightly attached to the surface of the walls of the whole spherical house, and there was no gap in between.

Think about it another way: if we stretch the rubber belt around the surface of an apple, then we can neither tear it off nor let it off the surface, so that it slowly moves and shrinks into a point.

On the other hand, if we imagine that the same rubber belt is stretched on a tire face in the appropriate direction, then there is no way to shrink it to a point without tearing off the rubber belt or tire face. We say that the apple surface is "single-connected", while the tread is not. ”

A lot of people are a little confused. But it's not their fault.

"I don't think I need to prove it, I think I can think of it."

"I don't know how you guys are? Anyway, I don't know what he's talking about right now. ”

It seems that this is easy to figure out, but mathematics is not "just thinking about it" to prove a conjecture, it requires rigorous mathematical reasoning and logical reasoning. For more than a century, countless scientists have racked their brains and even devoted their lives to proving it, but to no avail.

From this point of view, it is still a very difficult problem to solve.

Poincaré, the scientist who asked this question, asked many groundbreaking questions in his lifetime, and his life's achievements were not in his achievements, not in how many problems he solved, but in how many questions he asked, and this conjecture was only one of his many conjectures.

Not only are the people below a little blindsided, but even the host doesn't know what Liu Shiyuan is talking about.

The three of them didn't know what question to ask, but Zhao Bingbing, one of them, said smartly: "May I ask the boss, we don't understand why we ask this question, and what is the use of asking this question?" ”

Liu Shiyuan looked at everyone and said: "I also believe that many people think so, which is helpful for us to study spatial streamlines, or in fact, we are using mathematics to calculate a spatial equation." I'm sure no one will write the answer to this question anytime soon.

If no one has answered this question in ten years, I will mention this method of calculation in my book "Dream World". ”

At this time, many scientists got the news, and Liu Shiyuan once again published his mathematical conjecture.

Many people want to see what Liu Shiyuan is proposing.

"Boss, have you solved this problem?" Zhao Bingbing said in surprise.

Liu Shiyuan said with full confidence: "I am researching, and I believe that I will definitely be able to study this problem in ten years." ”

"And one last point, boss, you sing songs on CCTV and in many areas, I wonder if you can bring you a song here too?" Zhao Bingbing said.

This is also a concern for many people.

"After everyone said this, I think if I were a different song, it would be really not interesting, okay, I did prepare a song, this song is not Chinese style, not Cantonese song, but it is definitely a very, very relaxing song, I also believe that it can bring many people happiness."

"It's really good, I have long wanted to listen to Liu Shiyuan sing songs, but I just don't have the opportunity, I really don't want to come this time, what you don't know is that I don't know anything about mathematics at all, I am sleeping every time I take math class, I can come today because I want to see our most famous genius in China." I like his songs more. ”

"Liu's products must be high-quality."

Liu Shiyuan handed the USB disk he was carrying to the sound engineer.

"This song is still composed by me and by Liu, the music master. "Walking on the Country Road" is given to everyone, I hope you can like it, and I hope you can all wish for success, health and safety. Liu Shiyuan's voice sounded.

The hosts all withdrew from the stage.

Especially Zhao Bingbing, she really can't figure it out, how many things are in Liu Shiyuan's head?

How his songs are one after another. And all classics of classics?

Each has its own merits.

There is no song that no one cares about, and there are always many people who follow the song.

Liu Shiyuan is very golden, and Liu is not an ordinary creator at all.

They are simply classic making machines. (To be continued......)
