Hammer of Technology

But it's all in English.

It is more laborious to read, but now this is no obstacle for Ning Wei at all.

Yes, Ning Wei had a whim. Now that he sees a topic, he can infer other things from it. So what will happen after reading the papers published in the world's top journals?

He wants to try.

However, at a glance, big news was discovered.

An American scientist named Smith Heath Front published a paper claiming to prove that the NS equation is not unique.

In other words, the uniqueness and smoothness of the NS equations are disproven.A more detailed description is that its three-dimensional overall smooth solution is proved or rejected.

The paper quickly aroused Ningwei's interest.

If this paper is correct, it will be a major event that can subvert the world of mathematical theory, and it will also have a profound impact on the world of physics.

Not to mention that Ning Wei still remembers that when a professor of mathematics talked about the NS equation, he also said that the current research on the solution of the NS equation in the mathematical community has been completely solved in the two-dimensional case, and it has been proved that the three-dimensional short-time smooth solution exists .

Why was it suddenly falsified?

------------

008 Pure number field

The full name of the NS equation is the Navier-Stokes equation.

At the same time, it is also one of the seven millennium mathematics problems specially listed by the Science Advisory Committee of the Clay Mathematics Institute of the United States.The main thing is to describe the equation of motion for the conservation of momentum of a viscous incompressible fluid.

In layman's terms, it is probably the mathematical model expression of fluid mechanics.

How famous is this math puzzle?

Let's put it this way, whoever can give a result that all mathematicians agree with, whether it is a proof or a proof, or just further promotes the explanation of this equation, will be able to get a $100 million reward from the Clay Mathematics Institute .

If there were no other better mathematical achievements in these years, such as solving the NP-complete problem or completely solving the four-color problem, basically the Fields Medal could be included in the bag.

In other words, if this paper written by this mathematician named Smith Heath Front can stand the test and be widely recognized by the world's theoretical mathematics community, it will basically be the next Phil Here's the winner.

When Ning Wei read this paper, he also checked the resume of this American mathematician. He was only 36 years old, and he did not exceed the maximum age limit of 40 years old for the Fields Medal.

And this is indeed a master in the field of theoretical mathematics, a standard mathematical genius. The one who was accepted by Harvard at the age of 16 is now a professor at Harvard and a member of the National Academy of Sciences.

Of course, the publication of this paper in the "Nature" journal has already shown that this paper is still in stock, at least it has been recognized by a small range of mathematics circles.

Otherwise, as the world's top journal, it is impossible to publish it directly.

However, the publication of this paper in "Nature" does not mean that this paper is correct.

With the development of theoretical mathematics to the point where it is today, difficult problems at the level of NS are no longer the era when the first few reviewers could give a definite review opinion.

Many similar problems are published first, and then theoretical mathematicians from all over the world discuss together to find faults. If they can't find faults, everyone can only give a thumbs up and praise the author.

If the paper is quickly overturned, you can just throw a sentence that the author is an idiot.

However, there must be no obvious mistakes in the paper. After all, as a top journal, the jury of "Nature" is still very strong.If any messy paper can be published in a journal, it will not be regarded as a top academic journal.

In the past, Ning Wei would definitely not waste time on this kind of paper.

After all, the things in the papers of the mathematics bigwigs are not something that can be understood by majoring in mathematics.

For the vast majority of undergraduates, researching these papers is nothing more than a waste of time.

But now Ning Wei really has the confidence.

……

Soon Ning Wei was immersed in this thesis.

The master's thesis is extremely proficient in the application of high-level mathematical language, which is why it is difficult for ordinary people to understand this type of paper.The simplest mathematical language, such as a, b, and c, is an arithmetic sequence, which can be directly expressed by a+c=2b in mathematics.

Higher-level mathematical languages ​​will naturally use more and more complex mathematical expressions.

These expressions are often the starting point of dyslexia.

But at this time, Ning Wei would automatically annotate the meanings represented by various expressions in his mind.

With the translation of various English terms, Ning Wei could even feel that his brain was running at high speed.

But soon he was immersed in the world constructed by this paper.

A whole new door is opening to him.

……

While Ning Wei was watching this paper, the world's theoretical mathematics community had actually exploded because of this paper.

In other words, it is not only the mathematics field, but also the physics field and related engineering fields.

Because NS equations describe physical fluid dynamics.

Of course, the NS equation is not the whole of fluid mechanics. In practice, it either fails or needs to be coupled with other equations.

For example, fluctuating hydrodynamics should be used for small scales; thinner gases have sliding boundaries, and dsmc should be used for thinner ones; Stokes Flow should be used for mesoscopic ones; in some special cases, Boltzmann equations or higher-order Burnett equations than NS equations should be used.

In other words, even if the NS equation is proved or rejected, it will not affect the current fluid mechanics.How should water flow or how should it flow, and how should an airplane fly in the sky or how to fly.

However, the entire academic community has always believed that NS equations can be used to describe the physical mechanism of fluid motion.Now that it has been falsified, doesn't it mean that all the various models that used the NS equation as their theoretical basis were built with a wrong theory?

It is conceivable how crazy the entire academic world is at this time.

To put it bluntly, the entire academic world has already been blown up because of this paper published in "Nature".

Although everything seemed calm to the outside world, it was because the scientists, as academics, would not think about posting a Weibo first and outputting crazily at the moment when their ideas exploded.The first choice must be to read the paper first.

Then whether it is support or opposition, you must come up with something conclusive.

Therefore, when various controversies or breakthroughs in the scientific community reach the ears of ordinary people, there is often a lag.

After all, it will take a long time for academic controversies and breakthroughs to affect the lives of ordinary people.Most people are more concerned about whether the stars have washed their faces when they go out today.

The omnipotent Internet greatly shortens the lag time.

But after all, this paper has only been published for more than a day, and the madness and controversy in the academic world have not had time to let Ning Wei and these mathematics students know about it. Of course, it is impossible for the outside world to react too much.

Or some niche public accounts have already reported, and people in related majors have started discussions on academic forums.But the real academic masters definitely don't have the time to deal with these things at this time.

For example, the masters of Peking University School of Mathematics.

As we all know, the Mathematics Institute of Yanbei University is definitely the number one in China in the field of pure numbers.

Probably even the Wudaokou Vocational and Technical College opposite them would not dare to refute.

After all, it was the first of the four madhouses of Yanbei University in the legend. A standard academic bully would mistakenly think that he was an idiot when he went in, and he didn't realize that he was actually quite smart until he walked out.

Although it was already ten o'clock in the evening, the Yanbei International Mathematical Research Center by the Weiming Lake was still brightly lit.

Several people in the office are sitting around their desks, reading this Smith Heath Front paper.

Needle drop could be heard in the office.

If Ning Wei came to this office at this time, he would not even dare to breathe.

Because the seven people in the conference room are all top scientists in the category of Chinese number theory or mathematical physics, there are only three professors with the title of academician, and the remaining four are also leading figures in the Chinese young generation of mathematics and physics.

------------

009 Ning is a classmate, calm down!

After a long time, a young man in the academic circle who looked only in his 30s or [-]s got up from the computer, walked straight to the window, and began to stare at the scenery outside the window.

It's just that the eyes are obviously not focused, and it's obvious that the brain still hasn't stopped thinking.

If there are students from the Mathematics Academy here at this time, they will immediately recognize that this unassuming guy is actually the youngest associate professor in the history of the Mathematics Academy of Yanbei University, and also one of the most legendary mathematics gods in the history of the Mathematics Academy Lu Dongyi.

He entered the national team directly in his freshman year of high school, and represented China in the International Mathematical Olympiad Competition, and won the gold medal with a perfect score of all six questions. In the same year, there were only three people who got all the questions right in the IMO.

The following year, the second year of high school participated in the IMO mathematics competition again, and won the gold medal again with a perfect score, which directly filled the honor.

Not to mention the questions that others can only complete in 3 or 4 hours during training, he can usually solve them in an hour.

In the third year of high school, he had no desire for honor and did not participate in IMO again. However, he was admitted to Peking University School of Mathematics without examination by virtue of his existing honor, and he still did not stop making history.

In his sophomore year, he won five golds and one silver in the Yau Mathematics Contest, sweeping everything by himself.

In the junior year, he won 2 golds, one silver and one bronze, so far he has won the Grand Slam of Qiu Sai.

After graduating from Ph.D., he got his Ph.D. in three and a half years. He has published more than 20 papers in various well-known SCIs. He is a standard academic figure.

Coincidentally, the research topic he chooses now happens to be the PDE direction under fluid mechanics, and has achieved a lot of results.

For example, the problem of quasi-spectrum and spectral lower bound of Oseen vortex operator, Lu Dongyi and his collaborators solved this conjecture through innovative methods, reconstruction, and mandatory estimation.

So when I saw this paper at this time, I was naturally delighted.

Not long after he stood up, another master came to his side.

This is Tian Yanzhen, a professor at Peking University School of Mathematics and academician of the National Academy of Sciences, who was his doctoral advisor.

"How is it? What do you think after reading this paper?"

"The divergence on a small scale always feels a bit weird." Lu Dongyi replied.

Tian Yanzhen looked at Lu Dongyi and sighed inwardly.

Age is also a big issue for scientists.

It also makes sense that the age of the Fields Medal is stuck at the age of 40.

40. 40 years old is the most vigorous time for a scholar. He is full of energy, broad-minded, quick to accept new things and respond very quickly. After [-] years old, it is basically a downhill road.

Knowledge and experience may have accumulated more abundantly, but memory, thinking ability and reaction are all in a decline stage.

Just when Tian Yanzhen sighed, Lu Dongyi started talking to himself again.

"In fact, this is a problem in an extremely turbulent system. We use the NS equation to model the fluid. The initial energy of the fluid will be gathered in the turbulent flow, and the dispersed kinetic energy in the fluid may be gathered in any small eddy. So Particles in a vortex can theoretically be accelerated to infinity."

"The smaller the scale of this research, the weaker the control effect of kinetic energy on the solution of the equation. So the solution can be arbitrary. The problem is how to limit this solution. The results given in the paper cannot be limited, so we cannot get a unique solution. Solution, the smoothness is proved..."

The voice of talking to himself became more and more vague, Tian Yanzhen, who kept listening, could only shake his head with a wry smile.

Well, this guy is stuck in the mathematical world he built again, and he also gave up the idea of ​​​​communication and returned to his position.

But then again, a paper of this level solves a world-class problem. It is normal for the academic circles to quarrel for several years after it is published in Nature.

It is whimsical to get results in a short time. He should continue to study, maybe he can give these young people some inspiration?

……

River City University.

Ning Wei finally finished reading this thesis completely. He was so immersed in academics that he didn't even feel the passage of time.

It made him speechless with a trace of joy, and the feeling of trepidation still persisted amidst the joy.

Because he really understood this paper.

Not only that, his brain also directly gave him feedback on the three major mistakes in this paper.

If the three major errors reported by his brain are correct, it is enough to support him to immediately write an SCI to refute the paper published in "Nature".

By the way, it can also promote the understanding of the NS equation in the academic world!

At this moment, Ning Wei even wondered if his brain was unknowingly enlightened by something.

Otherwise, why would he dare to have such an idea?

Send SCI to refute the world's top scientists, and push forward a big problem that plagues the theoretical mathematics community?

Does he deserve it?How many to match?

Yes, Ning Wei feels that she is really unworthy.

Unless his brain is really enlightened by a master, such as Gauss, Riemann, Euler, Newton, Einstein, after all, Einstein's achievements in mathematics are not as good as those academic giants of the same period them.

But the urge to try in his brain couldn't be restrained no matter what.

Just when he made up his mind to put all his eggs in one basket and start writing a paper to tell the whole world about the mistakes of this paper, the door of the dormitory "creaked" was suddenly pushed open, and at the same time, there was Liu Cong's loud voice.

"Ning Wei, good news!"

Ning Wei paused for a moment, and the creative impulse of his brain was interrupted.

He looked up at the time, no wonder, it was almost twelve o'clock.

In other words, it took him just over two hours to study this paper?

What kind of fairy speed is this?
