Comeback 1992

The weather is too hot, kind of stuffy.

Combined with the sunless sky, it is clear that a heavy summer rainstorm is brewing.

As soon as I entered the house under the eaves, a heavy rain suddenly swept through.

Han Songlin couldn't help laughing, feeling that today's luck is really good.

It doesn’t fall early, it doesn’t fall late, it will rain when I get home.

I believe many people have experienced this feeling.

God, this is too much face.

But when he entered the room, Han Songlin was stunned.

What's the situation?

Did you invite someone to come to your house for a meeting today?

Why are all the bosses from the Mathematics Department of Star University running here.

More than 20 people sat around together, but fortunately the living room in the house is big enough, otherwise it really wouldn't be able to sit down.

Han Yufei was surrounded in the middle, with a small whiteboard beside her, on which Han Yufei kept writing mathematical formulas and so on.

Then said with a small mouth.

Han Songlin said that he seemed to understand that it was Chinese when he said it alone, but he couldn't understand it together!

Liu Yuyan and Song Rong were in the kitchen, and the door of the kitchen was closed.

Obviously didn't want to be disturbed by the sound of the kitchen outside.

Chapter 871 Second Proposition

"What's the matter?" Han Songlin reached out and took a piece of stewed meat from the plate and put it in his mouth. There is really no shortage of stewed meat in this house.

There are many flavors of lo mei.

Liu Yuyan patted Han Songlin's hand: "Hands are dirty!"

Han Songlin raised his hands and signaled, "It's clean!"

Rolling her eyes at Han Songlin, Liu Yuyan put the cut vegetables on the plate.

"After you left this morning, they came. They were called by Qiuqiu. At noon, everyone made a donburi to eat." Liu Yuyan was really tired today.

Suddenly, I had to prepare meals for more than 20 people, and I didn't prepare at all.

There was not enough food at home, so I quickly called the supermarket to send some food over.

Han Songlin understood, now he is preparing dinner for the evening!

The preparation is naturally very rich.

If the kitchen in the house is not big enough, it can't be opened.

Liu Yuyan said in a low voice: "It seems that Qiuqiu proved the Riemann conjecture. Everyone was so excited that they were reading Qiuqiu's manuscript while eating."

There is a photocopier in the house, and I copied more than 20 copies of the manuscript, and each person took a copy, and combined with Han Yufei's explanation, he followed what Han Yufei said.

"The Riemann conjecture has been proven?" Han Songlin's voice was raised twice, and he carefully glanced at the kitchen door to make sure that the living room was not affected by his voice.

Han Songlin lowered his voice in disbelief: "Are you sure?"

Liu Yuyan shook her head: "I don't know, isn't Qiuqiu telling everyone now?"

She also has a little basic scientific literacy.

Knowing that a research has produced results does not mean that if you say it, it will be counted.

There must be a special expert group to conduct the review. Only after passing the review of the expert group can the result be considered real.

Whatever you say, it's not a mess.

I also said, I can build a nuclear fusion device!

This is no bullshit.

Han Songlin also realized that asking Liu Yuyan was asking the wrong person.

Slightly opened the kitchen door, and the voices from outside came in clearly.

"Do you have any other questions?"

"On the sixth page of No.20 of the proof, here is a question I want to ask, about..."

Han Songlin didn't understand what he was asking at all.

Han Yufei pondered for a moment, and then wiped off all the things written on the whiteboard with a rag.

Then write on it with an oil-based pen.

This oil-based pen is widely used in teaching and discussion in Star University.

Compared with the chalk used in class, using an oil-based pen to write on the teaching board is healthier for teachers.

Those who are teachers now basically have occupational diseases.

Among them, lung disease is quite serious.

The more responsible the teacher is, the more serious it is; these are left over from writing on the blackboard for a long time.

Han Songlin closed the door silently, but he didn't feel shocked because he couldn't understand their discussion.

I don't understand, isn't this a normal thing?

He was thinking about a question, how likely is Han Yufei to prove it?

Judging by everyone's reaction, it seems that there is a great possibility.

Later, just wait until the sound of everyone seems to be leaving.

Han Songlin and Liu Yuyan came out quickly: "Everyone, eat your dinner before leaving. Everything has been prepared."

"Boss, lady boss, we won't eat. We all have to go back and digest what Qiuqiu said today. Let's bother again tomorrow."

Seeing that he couldn't keep him, Han Songlin had no choice.

However, Han Songlin still left two people behind.

Liu Yutong and Yang Hai.

"Academician Liu and Academician Yang, do you think Qiuqiu's proof is correct?"

Liu Yutong and Yang Hai looked at each other, and then looked at Han Yufei who was sitting in front of the TV watching cartoons, "Let's Go, Xingchen" was playing on the TV.

When Chinese animation produced this animation, it fully drew on the experience of the previous "Xinghai", and made the storyline of "Xingchen" very long.

And it has the support of astronomers and physicists.

Han Yufei also wrote a long suggestion letter for Chinese animation.

Sent in an envelope from home.

When the Chinese animation sees the envelope, it attaches great importance to it, because the envelope is a special envelope for Xinghai Group headquarters.

"The two of us combined, this is considered an octogenarian! But I really feel that I have lived for so many years, and I have lived in vain."

Han Yufei's growth rate is really too fast.

In the first half of this year, Han Yufei has been studying in school, constantly asking questions from the professors in the mathematics department.

The School of Mathematics of Star University is the most powerful among all the universities and research institutes in Huaguo.

Also because of the powerful School of Mathematics, Xinghai Group also benefited a lot.

Many studies that require the use of mathematics can be solved for you, which feels very cool.

Research is afraid of being stuck.

If you get stuck in one place, you won't be able to do it later.

Only after the stuck place is broken through can the entire research project continue to advance.

Han Songlin: "Don't say it like this. If you say it like this, don't other people have to be ashamed to kill themselves to be able to thank the world?"

"Okay, stop joking. I personally feel that there is no problem with Qiuqiu's proof of the second proposition of Riemann's conjecture." Liu Yutong said, looking at Yang Hai.

Yang Hai is also a well-known mathematician in the world. He was invited by Star University to come back to do research.

Facing the invitation from Star University, Yang Hai came back after thinking about it for a while.

As far as the platform is concerned, Star University is indeed big enough.

It allows people to display their talents arbitrarily on this platform.

The most important point is the strong academic atmosphere of Star University.

Yang Hai spread his hands and said, "I don't see any problems. Her proof is extremely rigorous, and I don't think anyone else can find logical loopholes in her proof except herself. .”

Han Songlin had no doubts about the abilities and strength of Liu Yutong and Yang Hai.

In other words, Han Yufei really got it out of him.

"Now Qiuqiu has to write out her own proof and let the global mathematics colleagues review it. To be honest, there are probably not many people in the world who can understand it."

After they went back tonight, they had to continue studying Han Yufei's manuscript.

At this time, they all have a feeling of witnessing history.

"Many people believe that Riemann's second proposition is correct. But there is no way to prove it. Now it has finally been proved. For human mathematics, it is undoubtedly a huge leap forward."

Yang Hai nodded in agreement: "Now, the proof of Riemann's conjecture, maybe she is the only one in the world to prove it."

"Yeah, I am looking forward to the day when Riemann's conjecture becomes Riemann's theorem."

Han Songlin looked at Han Yufei. At this moment, she was just like thousands of children in Huaguo, staring at the TV with silly joy.

Chapter 872

etc!Why did Han Yufei end the seminar on mathematics?

Listening to everyone's meaning, it seems that I haven't fully understood it yet.

Watching TV, the corner of Han Songlin's mouth twitched involuntarily, and he seemed to have found the reason.

Liu Yutong and Yang Hai didn't eat at Han Songlin's house either, they had to go home and study it carefully.

Han Songlin sat next to Han Yufei, and the cartoon had to wait for a while before it finished.

Han Yufei glanced at Han Songlin, kicked off her shoes, and nestled in Han Songlin's arms to watch TV.

This was Han Yufei's favorite thing to do.

After the cartoon was over, Han Yumeng and Han Xuan didn't know where to come back.

Obviously, the two of them went out to play this afternoon.

That's right, with so many people in the family, it's impossible to play around.

Han Songlin asked curiously, "Where did you go?"

"My daughter's house."

Girl's house?

Han Songlin was very confused, who is this daughter?

Liu Yuyan brought the food to the table, and their meal time is relatively fixed now.

After the cartoon is over, it's almost time to eat.

"Academician Zhang Xia's granddaughter is called Nannan."

Han Songlin really didn't know this.

Zhang Xia is a member of Xingchen Academician, who mainly researches theoretical physics.

Han Songlin asked Han Xuan, "Is your niece pretty?"

Liu Yuyan rolled her eyes involuntarily, what kind of questions are they asking.

In other words, if my daughter is not pretty, will Han Xuan play with her?

Liu Yuyan felt that this question deserved a serious discussion.

Han Xuan nodded affirmatively: "Pretty!"
