Chapter 903: Poaching talents from the United States!
As far as Chang Haonan is concerned, as long as the other party agrees to hold the award ceremony in China, everyone will be happy.
The issue of face is secondary.
Of course, on the other hand, he really didn’t know what the original arrangement of this ceremony was -
The proof process of the Poincaré conjecture in the previous life did not cause any problems like last year. There was such a turmoil in public opinion that Perelman successfully refused to accept the award in the end.
Therefore, there is actually no prize for the Millennium Mathematical Puzzle.
This is the first time in his two lives.
In short, in his reply to Arthur Jeff, he first said that "the venue of the award ceremony cannot be adjusted at will according to the requirements of the winners", but then turned around and said that "the award ceremony will be held at the nearest Held at the International Congress of Mathematicians, Chang Haonan finally chose to see through this behavior, which was inconsistent with integrity.
He also wrote back highly praising the Clay Mathematics Institute's efforts in reducing extravagance and waste and practicing thrift.
I just don’t know if the person at the other end of the network cable will vomit blood after seeing it...
However, Yuan Xiangya's reaction next to him was still a little slow. After seeing this reply, he frowned slightly:
"Professor Chang, isn't this 'the nearest International Congress of Mathematicians' next year?" That time?”
“Yes.”
Chang Haonan said, closing the mail receipt interface, and then clicked on an email from the inbox.
Judging from the domain name, it should be from Ohio State University.
"But I remember...next year's class is already close to ten, and it's decided to start at BJ?"
Yuan Xiangya obviously still lacks some deep understanding of the attribute of "tsundere".
"Hey... foreigners, good face."
Chang Haonan shook his head helplessly:
"If I ask them to present awards in Beijing, then the other side must be I can’t agree directly, after all, there is no reason for the person who gives the award to be manipulated by the person receiving the award.”
"But having said that, because of what happened last year, Perelman and I don't have to accept this award, but for the sake of its own reputation, the Clay Institute must not not give it."
"So I can only find some ways to save face."
Yuan Xiangya felt that his visit today was really not in vain.
He has seen more anecdotes in this hour than in the past ten years combined -
People who think that $500,000 is a hot potato are begging for it. The awarding party that distributes money to the winners.
However, it is always a good thing.
The Chinese mathematics community has never been as proud as it is today -
More than half a century ago, there were some systematic achievements in theoretical mathematics in China.
However, as a poor and weak country at that time, China was inherently unable to make much noise in the international community.
This is true in any field.
Later, the Chinese people stood up.
As a result, Huaxia Mathematics fell again...
In short, it just did not catch up with the good times.
But now, it is probably the end of all the hardships...
Looking at Chang Haonan who was immersed in work again, Yuan Xiangya suddenly felt that even though he had passed the best age for performance, if If we change the route, it seems that we can't do something else...
"Then I won't disturb your work."
Thinking of this, Yuan Xiangya stood up and prepared to leave.
This time, Chang Haonan just sent him to the door of the office:
"I just received a very interesting paper, so I sent it not far away."
The two shook hands as a farewell.
"It doesn't matter, I understand this feeling."
Yuan Xiangya is also an academic after all, and he knows that Chang Haonan is definitely not an excuse:
"It's very frustrating to be interrupted when reading a paper. I won’t be this evil person anymore because of things that irritate people. Goodbye.”
…
After sending Yuan Xiangya away, Chang Haonan almost jogged all the way back to the computer.
The paper on the screen that was highly praised by Chang Haonan was naturally from the research group of Professor Harold Huang.
AfluxReconstructionApproach to High-OrderSchemesIncludingDiscontinuousGalerkinMethods (high-order flux reconstruction method including discontinuous Galerkin method).
Almost as soon as he saw the title of the paper, Chang Haonan was already Mesmerized.
After reading the abstract and highlight, he was basically determined to accept this article.
To put it simply, Professor Harold unified a series of compact and high-precision formats that have emerged in recent years through a method called "high-order flux reconstruction (FR)".
As long as different flux correction functions are selected in the FR method, almost all high-precision formats based on intra-unit polynomial reconstruction can be covered.
It can be said that this achievement is equivalent to the "grand unified theory" in its subdivision.
This is especially true for Chang Haonan.
High-precision format is a very hot research direction in the past two years.
However, this has nothing to do directly with Chang Haonan himself or the Torch Group.
If I have to say something, it can only be said that the emergence of the catfish TORCH Multiphysics has made the entire numerical calculation field active, thus giving birth to a series of achievements that did not exist at all in previous lives, or did not appear until much later in previous lives. .
High-precision format is one of them.
Theoretically, the advantage is that when sufficiently high-precision meshing is used, the calculation error can be controlled to a very, very low level.
Or in other words, if such a low calculation error is not required, the number of grids can be greatly saved. Taking the level set method studied by Chang Haonan as an example, when the error constraint is 1e-6, the grid size corresponding to the fourth-order high-precision format is 32 times the grid size corresponding to the second-order format.
In the three-dimensional case, the mesh amount can be reduced to 1/30000.
In this case, the additional complexity brought by the high-precision format itself is basically negligible.
However, the application scope of each high-precision format is quite narrow and the complexity is very high. If each format is written into the software separately, the amount of code data will increase to an unacceptable level. level.
And many complex engineering models cannot be processed in one format at all.
Therefore, the current official version of the software has not included high-precision formats in the update plan.
The FR method, if it is what the author said, can solve this problem perfectly.
As long as the user sets the flux correction function.
As for why such a significant paper was posted to JCAS... Chang Haonan can probably guess it.
Although the FR method solves the problem of "narrow application scope of a single method", in order to truly realize its application, two other obstacles must be overcome -
It is difficult to popularize with the level set method. The reasons are almost the same.
High-precision formats have extremely high requirements on meshing accuracy.
If the mesh is rough, the results of the high-precision format may be worse.
Moreover, due to the relatively poor adaptability of high-precision formats, it also requires high levels of engineers using CFD software.
Even with FR, it is impossible to solve some simple problems just by relying on software presets like traditional low-level methods.
This is the case in the field of numerical computing. Different people use the same software tools to complete the same topic, and the results are often very different.
However, in the current initial stage of the development of the CFD industry, the level of the vast majority of users is difficult to describe.
Therefore, the industry is generally not optimistic about the development prospects of high-precision formats in the short term.
Even Chang Haonan was like this before today.
It’s just that he is two steps ahead of others -
Torch Group not only has the only meshing algorithm in the industry, but also has numerical calculations specifically responsible for “after-sales” The business department even has regular numerical calculation business training.
This is also one of the core reasons why TORCH Multiphysics dares to set high prices.
In other words, there are three big mountains facing competing products.
Go over one and there are two left.
But Chang Haonan was already standing in front of the third mountain. After climbing over another mountain, the road would be smooth.
The FR method in front of me is not even a trekking pole.
It's a shield machine.
You can just dig a tunnel out...
Thinking of this, he quickly threw the paper into the folder that was published in the first issue, then picked up the phone on the table, Prepare to ask the Torch Group office to send an email to Professor Harold in the name of the company.
See if you can poach the opponent directly.
However, after pressing two numbers, his right hand was hanging in the air again.
Due to the interruption of the dialing action, the receiver soon sounded a tone indicating that the phone number was empty.
After struggling for a moment, Chang Haonan put down the phone again.
Although Torch Group has gained a certain reputation in the industry, in the final analysis it is still a Chinese company.
It is now the beginning of the 21st century.
Even though Chang Haonan has used various means to make China develop much faster than in the previous life, for people who have not experienced the two timelines, this contrast cannot be felt.
Therefore, going abroad or even immigrating is still a lifelong dream and goal for many people.
Poaching people from developed countries, especially the United States, which seems to be still at its peak at this time...
It is more difficult.
Affected by the propaganda from the United States, China's image in the eyes of Americans, if not still at Daiqing, is at least not much different from that of a large South Asian country.
So, if you send someone an email so suddenly, I’m afraid the effect won’t be very good.
Still need to lay the groundwork.
Furthermore, Chang Haonan also had to confirm whether Harold Huang really had ink in his stomach.
After all, the journal editorial department is not responsible for the authenticity of the content of the paper.
But as a leader, he must be responsible for the development of the company.
With this in mind, Chang Haonan had a new plan in mind.
So, he picked up the receiver again and quickly dialed the number of the Torch Group's office.
“Hey, Old Song, it’s me, Chang Haonan.”
“Please remember to make arrangements. When the TORCH Multiphysics 2.0 version is officially released in the second half of the year, we will hold a numerical algorithm and calculation Science conference."
"Yes, for the whole world."
"You can consider the specific format and arrangements. The group will mainly bear the funding. Of course, it would be better if someone else is willing to sponsor it. .”
"Well...if our friends are willing to participate, we welcome them with both hands!"
