Comeback 1992

"Where are Han Xuan and Han Yumeng?"

Han Yufei: "Han Xuan went to play with his classmates. The second sister is sleeping in the room."

go to bed?

Sleepy in spring, tired in autumn, nap in summer!

There is nothing strange about sleeping.

"Didn't you go to school today?"

As for where did Liu Yuyan and Song Rong go?

Han Songlin didn't ask, maybe he's meeting someone to play cards.

When a group of people have nothing to do, they make an appointment to play mahjong together.

Han Yufei: "I've been there, and I'm back again. Grandpa Li said that he would hold a lecture on the proof of the second proposition of Riemann's conjecture at school, and I agreed."

Han Songlin didn't care about Han Yufei's private decisions.

She is capable of making decisions for herself.

"Are there many people coming to this lecture?"

Needless to say, the importance of Riemann's conjecture.

Just looking at more than 1000 theorems of human beings based on the correctness of Riemann's conjecture, we can know how important it is.

After more than [-] years of struggle, human beings have proved the first proposition of Riemann's conjecture; after another century and a half, human beings have finally proved the second proposition of Riemann's conjecture.

So, the third proposition of Riemann's conjecture, even Riemann himself is not sure that it is correct, can it be finally proved?

Perhaps, we have to continue to wait, and wait for hundreds of years before human beings can come up with proof.

To be honest, this situation is too normal.

Or maybe, it won't be long before it can be resolved.

"It should be a lot. I don't know." Han Yufei really didn't care too much about this. She knew that her proof was not a problem.

Mathematics is like this, if there are problems, there will be problems, and if there are no problems, there will be no problems.

Han Songlin smiled lightly, and couldn't help rubbing Han Yufei's little head. How could this little head be so smart?

It seems that whether a person is smart or not is not necessarily directly proportional to the amount of brains.

Han Yufei straightened out her hair. Because she was too lazy to take care of it, Han Yufei's hair was not long, it just reached her shoulders.

She even wanted to have the same hairstyle as Han Songlin, but Liu Yuyan firmly opposed it.

Liu Yuyan has no objection to engaging in scientific research and being a scientist, on the contrary, she is very proud.

But when Han Yufei wanted to keep Han Songlin's cut, Liu Yuyan naturally firmly opposed it.

Girls, you still have to look good.

Han Songlin rested his chin with his hands: "I will ask Fuller Hotel to handle the reception."

Han Yufei: "Grandpa Li said that the school will pay for the entertainment expenses!"

Han Songlin sneered: "Is there any difference between going out from school and going out from me?"

Han Yufei couldn't help but also smiled, it didn't seem to make any difference.

There are also donations from Star University, but the biggest source of funding for Star University comes from the Xinghai Group and financial allocations.

Financial allocations are divided into two parts, local financial allocations and central financial allocations.

In total, there can be more than one billion a year.

Star University itself also has some income, mainly from the transfer and authorization of technology patents.

Chapter 874 Countless Great Gods Are Coming

On August 20th, the students of Star University began to return to school, and the freshmen also completed their registration and officially started military training.The students returning to school naturally did not immediately enter the learning state.

It will take some time for many people to completely subside the impact of the holiday.

Some people are looking forward to returning to school at home.

For example, in the library of Star University, there are already quite a few students sitting quietly and reading.

At this time, there are still 25 days left before Han Yufei's speech.

The lecture will be held at Star University on September [-]th, and the invitations have already been sent out.

As for the person who invited him, he was the world's top mathematician.

These mathematicians have seen Han Yufei's proof of the second proposition of the Riemann Hypothesis before.

Not even just once, but several times over and over again.

I have to say that they didn't find any loopholes in Han Yufei's proof, and the whole proof was perfect.

It feels that when Han Yufei proved it, she intentionally wrote the whole proof process perfectly.

I am afraid that others will not understand what I am writing.

Considering that Han Yufei is only 12 years old, well, 12 years old, I don't know how many people know Han Yufei's age, and she looks heartbroken.

People were able to prove the second proposition of Riemann's conjecture when they were 12 years old, but when I was 12 years old, I didn't know how to play with mud there!

Maybe he wasn't playing with mud, maybe he was playing with bugs.

Anyway, that's what it means.

After receiving the invitation letter, all mathematicians who were free basically agreed to the invitation. They wanted to come and listen to Han Yufei's speech together.

At this time, in people's minds, it was actually confirmed that Han Yufei's proof was correct.

But everyone wanted to confirm it at the lecture and listen to Han Yufei's speech.

At this time, a heavyweight mathematician came to Rongcheng ahead of schedule, his name was Qiu Chengtong.

A mathematician with great reputation in the world.

When they found out that Qiu Chengtong had come to Star University, Han Songlin and Han Yufei came to Star University together.

Qiu Chengtong looked at the little girl who looked like a jade carving in powder in front of her. This summer, she made the whole world feel crazy because of it.

"Little princess, Qiu Chengtong sends you hello!"

Han Yufei looked at Qiu Chengtong with wide eyes, and saw the smile on Qiu Chengtong's mouth.

She stood up straight and looked very serious: "Grandpa Qiu, I am very happy to accept your greeting. Please allow Han Yufei to send you greetings. I wish you a long life and a lot of math problems!"

Saying that, Han Yufei also saluted Qiu Chengtong.

Qiu Chengtong couldn't help laughing out loud.

Han Yufei's tutor is very good!

"Professor Qiu, I've heard you famous for a long time, and I finally meet you today!" Han Songlin shook hands with Qiu Chengtong happily.

Qiu Chengtong is also very satisfied with Han Songlin's enthusiasm. As a world-renowned mathematician, he naturally has his own pride.

Qiu Chengtong didn't think much of capitalists.

But Han Songlin was different.

Unlike all capitalists in the world.

What other capitalists think about every day is to make money, and then continue to make money.

But Han Songlin is also making money, but he will continue to invest in scientific research.

Over the years, no one actually knows how much Xinghai Group has invested in scientific research.

The Xinghai Group no longer announced its investment in scientific research.

Perhaps, we can only get a peek at one or two of the company's funding from Huaguo's announced scientific research funding.

Why does Xinghai Group no longer announce its investment in scientific research?

The main reason is that there is no need for Xinghai Group to attract talents in such a way.

Another point, Han Songlin considered that Xinghai Group's investment in scientific research in the country was too high.

It is easy to be hated.

Those who know will always know, and those who don't need to know, don't know.

"I've always heard of Director Han's name!"

Qiu Chengtong gave Han Songlin a thumbs up: "If Huaguo has a few more big entrepreneurs like Han Dong, our Huaguo is not strong, and we can't do it."

Han Songlin: "It's overrated. In Huaguo, there are many entrepreneurs who are doing better than me."

Huaguo's achievements today are the result of the joint efforts of 13 billion Huaguo people.

Han Yufei couldn't help curling her lips when she heard them bragging about each other in this business.

Han Songlin noticed Han Yufei's movements and didn't care.

Han Yufei didn't need to pay attention to these things in the future.

"Professor Qiu, let's go inside and talk!"

Everyone sat down in the reception room.

Han Yufei and Qiu Chengtong were assigned to the main seat, and Han Songlin sat next to Han Yufei.

How do you feel that Han Songlin got such a seat because of Han Yufei's father status?

In the reception room, Yishui is full of top domestic mathematicians.

In addition to top mathematicians, many promising mathematics students were also called.This kind of high-end exchange is a rare learning opportunity for students of the Department of Mathematics.

The Department of Mathematics of Star University is very strong, and naturally it has recruited quite a lot of outstanding mathematics reserves.

Huaguo's top mathematician, Star University occupies the fifth floor exclusively!

This is undoubtedly a very large number!

The Mathematics Department of Star University ranks first in the country and the top ten in the world. In the latest university professional rankings, the Mathematics Department of Star University barely entered the tenth place.

Of course, if the second proposition of Han Yufei's Riemann Hypothesis is confirmed, then the ranking of the Department of Mathematics of Star University will be greatly improved.

"Qiuqiu, I have read all your proofs. I can't find any flaws in your proofs."

No flaws can be found, and this is not his kind words.

That's the truth.

It is amazing that a 12-year-old girl can do so much.

"how did you do that?"

Han Yufei thought about it seriously, and then said, "All you need is a pen and paper."

What I said makes people wonder how to evaluate it.

As a mathematician, isn't it possible to study mathematics with a pen and paper?

Han Songlin helped his forehead, this inadvertent poisonous tongue is the most hurtful!

The others present couldn't help but shook their heads and smiled wryly, they really couldn't envy Han Yufei's talent.

No matter how envious, I will not be envious.

They seem to have seen that the mathematics of the entire human race will be under Han Yufei's rule in the future.

Qiu Chengtong came to Xingchen University, of course he couldn't come in vain, academic exchanges and so on must be needed.

Han Songlin stayed with him all afternoon.

Qiu Chengtong and Han Yufei communicated in mathematics. Many times, Qiu Chengtong couldn't keep up with Han Yufei's thinking.

Facing Han Yufei's question, he had to think for a while before he could answer it.

Chapter 875 Invitation

A group of people continued to communicate, and then an afternoon passed.Until Han Yufei raised her hand and looked at her small watch.

It was a delicate lady's watch, and it looked very small.

Specially made for women.
