From small town academic to chief scientist

Existence and smoothness of Navier-Stokes equation.

It is a super difficult problem that has troubled the mathematics and physics circles for more than a hundred years.

Around the 19th century, many mathematicians and physicists saw that the theoretical fluid was too far from the actual engineering practice, and tried to add a friction term to Euler's ideal fluid motion equation.

Many famous mathematicians and physicists have modified Euler's equation in their own different ways.

Among them, Stokes used the dynamic viscosity coefficient μ for the first time.

Now, the basic equations for these viscous fluids are called Navier-Stokes equations.

Zhou Yi is now preparing to gradually solve this problem.

In the process of studying the NS equation, it may bring other surprises.

You know, whether it's a breeze or turbulence,

They can all be explained and predicted by understanding the solutions to the Navier-Stokes equations.

If you master the prediction of breeze and turbulence, it will not only have some applications in controllable nuclear fusion, but also

It can also be used in fighter jets.

In conjunction with Zhou Yi's original research on dark matter, it can even be applied to interstellar missiles.

Currently, two-phase flow is mainly studied in China because two-phase flow can be applied in all directions.

It has high application value and economic value.

Three-phase flow only remains in the theoretical stage, with few practical engineering applications.

However, in Zhou Yi's view, it is not that there are few practical engineering applications, but that there is no direction for application.

As Zhang Yitang said at the beginning, maybe some theories have no application value for the time being, but it does not mean that there will be no application value in the future.

Maybe people just haven't found its application value yet.

However, Zhou Yi did not intend to publish the research results of the NS equation in the end.

Because many people know its application value, Zhou Yi does not care about a millennium problem. What he cares about is whether others will use these theories to create something powerful to deal with Daxia.

So Zhou Yi thought for a long time. It would be good to study the BSD conjecture while studying the NS equation.

Because the BSD conjecture is essentially about number theory,

Regarding the content of this piece, Zhou Yi said that he was very familiar with it.

Even though there are many people who have a deep understanding of the BSD conjecture and have the powerful tool of Zhou's analytical method,

But no one has solved it after so many years.

Zhou Yi could only say that the opportunity was given to them. If they didn't cherish it, they couldn't blame themselves.

It's been three years, and you still can't solve the Riemann Hypothesis and the BSD Hypothesis. Zhou Yi is also very helpless.

Except for those old guys in the entire mathematics world, only Xiao Wanyi of the younger generation could make him take a second look.

If other mathematicians knew Zhou Yi's thoughts, they would definitely want to confront Zhou Yi.

Mathematics, especially number theory, has been developed for so many years and there are many tools. However, no one has solved the famous conjectures.

This requires not only hard work and talent, but also that elusive inspiration.

Inspiration is something that can only be encountered but not sought.

Zhou Yi now has no scientific research results every day, not to mention that it is not a problem to study two Millennium Problems at the same time.

There is no pressure to study three Millennium Problems at the same time. At most, time will just slow down a bit.

Only those with Ph.D. degrees in mathematics have been under great pressure for three years, and they are afraid that Zhou Yi will accidentally make some big move again.

They were unable to graduate. At that time, Zhouyi published a major result every few months, which really shocked the mathematics world and the academic world.

If the imperial court of Daxia had not asked Zhou Yi to apply it,

It is estimated that many doctoral students will have to postpone their graduation in the next two years, and may even hang themselves at the gate of Chongqing High School.

Just when Zhou Yi was checking the literature every day and reading about the NS equation results and BSD conjecture results in the past ten years,

Sure enough, Chou Guo couldn't help it anymore and told what happened on October 1st.

The exaggerated description made it obvious to the world that it was a problem in Daxia.

[Oh my God, it’s unimaginable that it would be like this. Daxia’s technology could actually block the connection between aircraft carriers and fighter jets.

What kind of communication technology is this? Why do I feel like when the ugly country beat up Ira K? 】

[The application of modern technology has changed the pattern of war. I just want to ask when will Daying have such a fighter jet? 】

[Unable to aim. It’s hard for me to imagine what kind of technology this is. Neither radar nor satellites can scan it. If a fighter jet reaches our airspace, does that mean we can just wait to die?

What does the Academy of Sciences use such high annual funding for?

Being overtaken by the rising star of Great Xia, I want to protest and demand that Da Ying announce its finances! 】

[Zhouzhou Oppa, come back quickly. We in Korea really need this kind of technology.

We want to dominate the universe. 】

Countless people left messages under the video released by Ugly Country.

At first, everyone thought that the Chou Kingdom was just joking, but now the Chou Kingdom’s court has announced it so solemnly,

I don't think it's false anymore.

Europe held a meeting again,

The president of Country F, classmate Xiao Ma, had a gloomy look on his face. Originally, Europe was already a mess.

Now Daxia's technological leadership has made countless people feel chilled.

If the performance of Daxia's engines were improved, wouldn't it be possible to fly quietly over Europe?

The President of Italy said:

"We suggest that Brother Ma send out an aircraft carrier to test the situation and see if it is as evil as Chou Guo said.

Practice is the only criterion for testing truth. If this is really the case, we can talk to Daxia Kingdom first. "

Classmate Xiaoma said:

"Forget it, I would rather believe it is true. That Zhou Yi is a genius. There will always be a genius every few decades or hundreds of years, right?"

Everyone had a lonely chat, and then left with their own thoughts.

You definitely need to ask Daxia if they can sell this type of fighter jet.

If other countries buy it, wouldn't it be like having a sword hanging over your head if you don't buy it?

Who can sleep at night?

After the presidents of various countries return home, they immediately go to the Academy of Sciences.

In any case, we must at least develop anti-stealth technology and know whether there are any aircraft in our airspace.

Otherwise, live in the air-raid shelter every night?

Xiao Ma repeatedly asked the academicians of the French Academy of Sciences.

"No matter how much money is spent, anti-stealth technology must be developed for me. I don't want a knife hanging over my head, and I don't want to sleep in a bomb shelter at night."

Not only the French President Xiao Ma, but also the entire European Union and the academies of sciences of various countries around the world are under great pressure.

Daxia Kingdom would do something like this, which would frighten everyone to death.

Fortunately, the plane can't fly far, and it can't reach Europe and Australia. It's just that Asian countries are unlucky.

But this does not mean that Daxia's technology will not make breakthroughs in the future.

What if there is a breakthrough?

Preparing for a rainy day is what their leaders should consider.

For a time, scientific researchers in various countries complained endlessly.

All were rolled up.

I was already under great pressure in scientific research, but now I was directly interviewed by the president.

You can imagine how much pressure there is.

Scientists all over the world were so troubled by Zhou Yi that they couldn't sleep at 3 o'clock in the evening.

The peace-loving country of Daxia will definitely not mess around, but the suspicious character of its own country's leaders will definitely not give up.

In particular, the top leaders of North and South Korea, island countries, South Vietnam, Asan and other countries almost broke through the door of their own national academies of sciences.

I have to go for a reminder almost every day.

For example, the Korean Bangzi and the South Vietnamese Monkey not only urged each other every day, but also sent various envoys to Daxia to seek peace.

Only Dongying and Asan didn't believe in evil, and wanted to test whether it was as evil as Chou Guo said.

When they confidently dispatched fighter jets, they were already known by the satellites in the sky.

Every move is under surveillance.

When General Li, who was in charge of the western military, saw this scene, he sent out the new J-20 to meet with them without thinking.

The result is no surprise,

A scene exactly like the one in Chou Country was staged.

The top officer of the Asan Air Force Command collapsed on his chair, his face full of disbelief.

They pride themselves on being a great country with a strong military, not inferior to Great Xia.

I didn't expect that the strength would be stretched so far now.

If I had known that Zhou Yi was a scourge, I should have killed him when he came to India to receive the Ramanu Gold Award.

The top commander of the island country's air force was no different from Asan, slumped in his chair, very desperate.

"Baga, the Academy of Sciences must develop anti-stealth technology, otherwise we will never be able to sleep peacefully."

Matsushita slapped the table fiercely, then got up and went straight to the Academy of Sciences.

Zhou Yi also received the news at this moment. The test between Asan and Japan undoubtedly made the country that originally had doubts put down its doubts.

It became an active cooperation with Daxia.

Zhou Yi was interviewing the elder at this time.

"Elder, do you mean to tell us about the performance of our aircraft?"

The elder said kindly:

"That's right, after testing it so many times, they have tested the performance of the aircraft to the point where it is indistinguishable.

We might as well admit it openly and give them some deterrence. "

In fact, after several years of edification and cooperation with various senior officials, Zhou Yi also understood some politics and said:

"good."

The elder thought of something and asked thoughtfully:

"Zhou Yi, do you think this new fighter jet can be sold now?"

Zhou Yi looked into the elder's eyes and understood what the elder meant.

Zhou Yi said without reservation:

"Yes, they cannot imitate the technology of every aircraft. We will set up a program so that once someone dismantles it, it will be destroyed automatically.

Secondly, these fighter jets are detectable under our integrated air-sea-air-ground system.

Our procedures can also be changed so that once a fighter jet flies to our border, we will be automatically notified. "

Zhou Yi thought for a while and decided to tell the elder in the most reassuring words,

"We have the absolute technology to detect the movements of these sold fighters."

After saying these words, the elder laughed and said:

"Okay! Then I'm relieved. How about letting you play with the new fighter jets when they are sold?"

Anyway, there won't be any problems at home. "

Zhou Yi wanted to refuse immediately, but the elder continued:

“Actually, you can go and have fun, you can also bargain with them and set the price.

Dongying and Asan have given us two free advertisements. "

Zhou Yi thought about it and found that it seemed possible. The conversation should not last more than a few days and would not delay his study of mathematics.

So Zhouyi said:

"Okay. I'm going to have some fun. Can I bring my family with me?"

Zhou Yi felt that he had been married for so long and took advantage of the first anniversary of his wedding to go out for his honeymoon.

The elder smiled and said:

"Okay. It's not a big deal. We have the right to be so domineering. They begged us, not us.

You can give me whatever face you want, they will come back to beg us in the end anyway. "

Zhou Yi also understood what it meant. As long as these countries did not make technological breakthroughs for one day, they would have to come to Daxia every day.

Daxia can show them whatever they want.

Moreover, Zhou Yi went there in person to give them face.

Today is different from the past. Back then Zhou Yi was just a well-known scholar, but now Zhou Yi is a top scholar who determines the direction of the world.

Being able to communicate and negotiate prices also gives them face.

Zhouyi asked:

"What countries are probably interested in buying?"

The elder said:

"There are many. Europeans all want to buy them, followed by the Middle East and other places, as well as various Asian countries. There are too many. You can slowly talk to them when the time comes."

Zhou Yi smiled and said:

"I'll just go there and watch the excitement."

"Haha, just ask Xiao Sun what you need. If he can't satisfy it, let him report it. We will find a way to satisfy it. You are our national treasure."

The elder said finally.

Zhouyi said:

"good."

After Zhou Yi sent the elder away, Zhou Yi returned home and told Xia Xue the news.

"Xue'er, do you want to see how other countries beg us?"

After Xia Xue knew the whole story, she thought for a while and asked:

"Senior, can you please bring back some cultural relics? I see that there are many cultural relics from our country in the Daying Museum.

There are also many cultural relics from our country in island countries. Can you bring some back? "

Zhou Yi thought for a while and said:

"You can give it a try. They begged us anyway, and we have absolute dominance."

Xia Xue said:

"There are lost fragments of the Yongle Grand Ceremony abroad. You can get them back. I want to see them."

Zhouyi said:

"Yes! Speaking of Yongle Dadian, I also like the sword of Emperor Yongle very much.

Come back together. Otherwise I will not admit the sale. "

The sword that Emperor Yongle awarded to the Living Buddha was the one Zhu Di himself used.

Zhou Yi clearly remembered that the sword was 90.3 centimeters long, with a blade length of 76 centimeters. The sword body was made of fine steel, and the hilt was covered with pearl patterns.

The blade of the sword is also engraved with two golden dragons.

The living Buddha was returned to Zhu Di after his death, but unfortunately he was taken away by the officers of the Ying Kingdom.

Zhou Yi thinks this sword is very beautiful and must come back.

The island country’s museums also have many cultural relics belonging to the Great Xia Kingdom, as well as Wang Xizhi’s authentic works.

Zhou Yi felt that he could come back.

Zhou Yi felt that it was very profitable to exchange the semi-finished sixth-generation machine for these.

And it’s just an included product.

If not, Zhou Yi will sell two new and improved fifth-generation fighter jets to Goryeo.

This is probably even more terrifying than Daxia having this kind of fighter jet.

When the engines of the sixth-generation aircraft are ready, the new fifth-generation fighter jets will be phased out.

Now, in addition to being a deterrent, this fighter is also used to make money.

I am a top scientist attending your negotiation. Isn’t it too much to ask for something from your museum?

Are you not going to give me any cards?

Then I'll sell you a hammer!
