Comeback 1992

There is no way to go on in the creation camp alone.

Now, no matter what industry you are in, it is difficult to go on without a team of people.

Unless it is said that your strength is surprisingly strong, let other people cooperate with you.

When they are performing, they will use the power of the team to cover up their individual shortcomings.

Liu Yuyan ate the next grape, and it is not the season for grapes to be officially launched.

Of course, as long as you want to eat, you can eat it all year round.

Glancing at Han Songlin and Han Xuan, Liu Yuyan's mouth twitched and spit out the seeds.

The hobbies of the father and son are really strikingly similar.

"Han Xuan, is the pretty lady on TV looking good?"

Han Xuan hesitated a little: "It looks good!"

"Compared to Big Mom?"

Han Xuan didn't answer right away, looked at Liu Yuyan, and then watched TV: "Auntie looks good!"

Han Songlin silently gave Han Xuan a thumbs up, he can talk!

Liu Yuyan giggled, satisfied with Han Xuan's words.

He got up and took the grapes and watermelon on the coffee table to Han Yufei and Han Yumeng who were reading upstairs.

Seeing Liu Yuyan leave, Han Songlin asked Han Xuan in a low voice, "Is it the young lady on TV or your aunt?"

"Truth or lie?"

"lie!"

Han Xuan supported his head, and said leisurely: "I have already said it before."

It has been said!

Han Songlin looked at Han Xuan silently, this little guy is very smart!

Last time, Han Songlin went to Hongxing Middle School to inspect and saw Han Xuan lying on the table and not paying attention to the lecture.

At that time, Han Songlin remained calm.

After the final exam results came out, I planned to let Han Xuan know the truth about not being too arrogant.

But who knows, Han Xuan actually got double hundred marks in the final exam.

This had to make Han Songlin suspect that Han Xuan was a very smart child.

Is my gene too good?

But Liu Yuyan didn't know the conversation between the father and son, and didn't know how he would feel.

Perhaps, Liu Yuyan has already prepared in her heart. After all, no matter how beautiful she is, how can she beat time?

Han Yufei's room was wide open.

Han Yumeng was sitting on the bed, barefoot, reading a book in her hand.

Han Yufei was sitting at the desk, writing something.

Han Yumeng usually likes to go to Han Yufei's room, and even the two of them often sleep in the same room.

Han Songlin and Liu Yuyan naturally knew about this.

It is a good thing that the two sisters have a good relationship.

"mom!"

"Come and eat watermelon and grapes."

Han Yumeng stood up and picked up a piece. Seeing that Han Yufei didn't respond, she ignored her.

Liu Yuyan glanced at Han Yufei who was immersed in writing, but didn't care.

He whispered to Han Yufei, "What is Qiuqiu doing?"

"Prove the Riemann Hypothesis!"

Riemann conjecture Oh!

It's like a mathematical conjecture.

Chapter 870 What is the situation

The last time Han Yufei perfected someone else's proof, Liu Yuyan realized Han Yufei's talent in mathematics.In fact, Han Yufei's talent no longer needs people to be aware of it, but has been fully displayed.

In Star University, Han Yufei often discussed with the professors, and then left the professors speechless.

However, everyone was eager to teach Han Yufei.

Shouldn't the most gratifying thing in the world be that students are better than teachers?

One generation is stronger than the next!

Relying on Han Yufei, Star University took the opportunity to invite several internationally renowned mathematicians from abroad to teach at Star University.

Facing Han Yufei, a talented girl, everyone was shocked.

Shocked and ecstatic at the same time!

Huaguo has always produced talents in large numbers. Under their leadership from generation to generation, this is the biggest reliance that Huaguo has been able to go all the way from the wild and primitive for 5000 years.

Otherwise, it would have been submerged under the yellow sand of history just like the other three ancient civilizations.

Liu Yuyan stretched her head to look at the draft paper on Han Yufei's desk, all of which were filled with various numbers and formulas.

Seeing mathematics, Liu Yuyan expressed dizziness.

Forget it, let's not disturb Han Yufei's calculations.

Liu Yuyan walked out of the room lightly and went downstairs.

Han Yumeng glanced at Han Yufei, who was still immersed in the calculation, but did not speak. She took out a piece of toilet paper to wipe her hands, and threw it directly into the trash can.

Continue reading.

Liu Yuyan sat beside Han Songlin with a happy face, and said with a smile, "Guess what Qiuqiu is doing?"

"Study math?"

Liu Yuyan's expression froze: "You know?"

"What else can Qiuqiu do besides studying mathematics now?" This should not be something that can be guessed immediately.

"Riemann guesses you know?"

Han Songlin: "It seems to be number theory!"

What is number theory?

How does Liu Yuyan feel that she is too ignorant?

In fact, Han Songlin is not very clear about number theory, he knows that number theory studies the properties of integers.

What is an integer?

This is elementary school knowledge.

Positive integers, zero and negative integers form an integer system; integers do not include decimals and fractions.

比如说0、1、2、3、-10、-3、-2、-1这类的数就是整数。

Seeing this, is there a need for research on integers?

Anyway, having such an idea can only show our ignorance.

Although we don't understand, we only need to know the importance of research.

Exploring the mysteries of the universe should be the ultimate goal of human beings as intelligent creatures.

Han Songlin suddenly reacted: "You said, Qiuqiu is proving the Riemann conjecture?"

"Mengmeng said that, I saw Qiuqiu sitting there writing and drawing, so I didn't bother."

Han Songlin wanted to go up and ask, but he held back.

How important is the Riemann Hypothesis to humans?

The Riemann Hypothesis has three propositions!

The first proposition was taken by Riemann in one stroke, and he did not give a proof at all, so he wrote a sentence: This is the result of self-evident universality.

The relaxed and freehand tone has taken 40 years to prove.

The complete proof process was given by the Hans country mathematician Montgomert 46 years later.

For the second proposition, Riemann said with certainty that it was correct, and then said in a letter with a friend: The proof of the proposition has not been simplified to the point where it can be published.

Even Riemann himself was a little uncertain about the third proposition, and wrote very cautiously: This is very likely to be the correct conclusion.

Are mathematicians so unreliable?

For example, the Fermat conjecture should now be called Fermat's theorem.

Fermat wrote down his views on a problem on the margin of a book, but the key proof was missing, and finally came a sentence: because the paper is too small to write down.

Are you angry?

Getting old.

The Fermat conjecture was completed 358 years later, that is, in 1995, by the Chinese mathematician Wiles with the most difficult modern tools.

For Riemann's conjecture, don't think about the third proposition now. Human beings have not even proved the second proposition of Riemann's conjecture.

The proof has not been simplified enough to be published. What kind of proof is required?

Over the past century and a half, more than 1000 mathematical theorems have been established on the assumption that the Riemann Hypothesis is true.

If a counterexample is found and falsified, then this incomparably brilliant number theory building will collapse.

No one can tell how it will affect the development of human science and technology at that time.

Of course, such a situation should not happen.

We have to believe in the self-confidence and calmness of a great mathematician.

Han Songlin didn't really believe that Han Yufei could prove Riemann's conjecture. The Goldbach's conjecture was proved last time because someone had already given the proof, and then Han Yufei understood and understood the proof.

Then the proof was given in another way.

To be honest, apart from explaining Han Yufei's intelligence, it didn't seem to explain too much about other things.

Forget it, let Han Yufei do it.

Studying mathematics is also a very meaningful thing.

Because Han Yufei had to study mathematics at home, the summer trip was naturally cancelled.

Han Songlin didn't want to go out either, and there was nowhere to go when he went out.

The scenic spots around Rongcheng have already been there.

As for going abroad to play?

It's a good choice.

It's just that, let's not rush this matter.

In the next few days, Han Yufei's condition seemed quite normal, but she stopped going to Star University.

It's summer vacation, what do you go to school for?

The students are indeed on summer vacation, but for the school professors, there is no such thing as summer vacation.

Continue to do research.

Taking advantage of the lack of class, you can still devote yourself to research.

When it was meal time, Han Yufei was able to come down to eat on time.

Also go to bed on time.

Let Han Songlin and Liu Yuyan relax, everything is fine.

Until a week later, Han Songlin came back from the Xinghai Group in the afternoon, sweating profusely.
