The Military-industrial Scientific Research System of the Academic Master Chapter 896

Chapter 896 I will be the editor-in-chief

After sending Li Yabo away, Chang Haonan, who regained his good attitude, enjoyed the warm sunshine of early spring while starting to check his emails again.

Now, almost a year has passed since he and Perelman published the paper proving the Poincaré conjecture.

The heat on this matter has also cooled down a lot.

However, the term "popularity" ultimately refers to the media.

ˆAlthough there is also a saying and phenomenon of pursuing hot research directions in academia, unless it is a field such as biology or materials where the results are relatively short and fast, the significance is really limited.

So overall it is quite restrained.

On the other hand, compared to Perelman, who has been almost completely missing, Chang Haonan still has some traces in the past year.

Therefore, many institutions, scholars or students will still send emails to this mailbox.

In fact, this also includes Perelman himself.

Although he is basically missing from the outside world, his connection with Chang Haonan has never been broken.

In addition to the usual exchange of mathematical inspirations, perhaps because they have realized their long-cherished wish to solve the Poincaré conjecture, the content of the emails exchanged between the two also contains a lot of content that has nothing to do with research -

˜Music, life, art, literature and even philosophy.

Perelman is indeed a genius in the literal sense, and he has some experience in these fields.

Although Chang Haonan is not a professional, he is still a person who has experienced the Internet era. It is not a big problem to be a listener and a fan.

In short, they act like they have been friends for many years.

ˆThrough these daily email exchanges, Chang Haonan also learned a lot about the other party.

As a Jew, some of Perelman's relatives chose to immigrate to the Great Patriotic State after the collapse of the Soviet Union, but he himself chose to stay in Russia with his mother after traveling around the West.

Perhaps this is one of the reasons why the other party is usually taciturn.

For example, there is an email in Chang Haonan's mailbox right now that he received last week, asking if he knows how to remove the fishy smell from fish soup...

Of course, not all emails have such daily content.

Marian Mirzakhani, who had contacted him before and expressed her desire to come to Torch Lab for graduate school, but was rejected out of hand, sent another email nearly a year later.

She first said that she had converted from a master's degree to a doctorate at Harvard University, and thanked Chang Haonan for his encouragement and support last year.

Immediately afterwards, I asked Chang Haonan below about the feasibility of a research route, that is, whether it is possible to reversely use the idea of the Poincaré conjecture proof process to project the interface tracked in the three-dimensional or two-dimensional space into a higher dimension. space to be processed.

Concerning Mariam Mirzakhani, Chang Haonan actually didn't take it seriously when the other party sent her an email for the first time.

However, he vaguely remembered later that this woman seemed to be the first female mathematician to win the Fields Medal in her previous life.

The research direction seems to be geometry.

“Don't let me take my research interests astray...”

Chang Haonan looked at the content in the email and thought helplessly.

Even if they are both geniuses in the field of mathematics, different people have different specific talent directions.

Mirzakhani can make outstanding achievements in the fields of hyperbolic geometry and symplectic geometry, but it does not mean that she can reach the same height in another direction.

But, no matter what.

Since others asked the question sincerely, Chang Haonan didn't mind answering the question.

After all, firstly, he happens to be free, and secondly...

This problem is really his area of expertise—

It refers not only to topology, but also to the numerical calculation methods that he had been studying earlier.

[For solving this type of problem, you can try to learn about the level set method in the field of applied mathematics. During the numerical simulation of multiphase interfaces, this method is usually used to circumvent the parameterization process and directly use the Cartesian grid to solve the problem. Calculate curves or surfaces that change with time. However, from a theoretical mathematical perspective, this method still has the problem of non-conservation...]

At the beginning, Chang Haonan just wanted to briefly introduce the level set method itself to the other party, as well as some ideas for solving non-conservation problems in engineering fields, such as speed reconstruction of the level set method.

But as he wrote, he actually came up with some ideas.

So he immediately stopped typing, took out a piece of scratch paper, and began to calculate step by step.

However, the peaceful time did not last long.

Just when Chang Haonan felt a sense of hunger in his belly, he decided to go to the canteen and order cumin duck legs for dinner.

The phone on his desk suddenly rang.

　　is the white one.

This made Chang Haonan, whose nerves suddenly became tense, relax a little.

Outside phone calls.

Generally it's not anything particularly fatal.

After calming down, Chang Haonan picked up the phone receiver. “Professor Chang, you are well!”

Yuan Xiangya's voice came from the other side.

“Dean Yuan?”

Chang Haonan's brain was running rapidly, and he quickly guessed the purpose of the other party's call to him.

Perhaps just after the Poincaré Conjecture was proved, he once suggested that Yuan Xiangya could establish a comprehensive natural science journal like Science or Nature as a benchmark and representative of Chinese academic journals.

The other party also invited him to serve as the editor-in-chief of the journal.

●Today's phone call is probably about this matter.

“Is your journal already ready?”

“Professor Chang's words are obvious, right?”

Yuan Xiangya's words contained an unstoppable smile:

"You are the editor-in-chief of the Journal of the Chinese Academy of Sciences. If you really want to say it, this is the journal for all of us..."

“Can you tell me the specific situation of the journal?”

Chang Haonan did not continue to be polite, but went straight to the topic.

Mainly because he was really hungry.

There is no large-scale takeout industry these days. If you find someone to take food out, it will be hard to come back.

"certainly."

Yuan Xiangya replied:

“At present, it has been initially determined that the journal will be published quarterly, with paper and electronic versions published simultaneously. In principle, submissions in both Chinese and English will be accepted, but only the English version will be published regularly, and the Chinese version may be published irregularly in the form of special issues.”

“The editorial department operates independently of the institutes of the Academy of Sciences and operates in parallel, and is only responsible to the Academician Conference and the Presidium of the Academic Division…”

It can be seen that in order to avoid some long-standing abuses in the academic circle as much as possible, the Academy of Sciences has set a fairly high level of independent authority for JCAS journals.

Coupled with this is Chang Haonan, the "externally hired" editor-in-chief.

It can be regarded as a great effort.

Considering that establishing China's own academic system is one of Chang Haonan's goals, he naturally has no reason to refuse this job.

Therefore, after listening to Yuan Xiangya's introduction, Chang Haonan immediately asked:

“Dean Yuan, when do you plan to publish the first issue of this JCAS journal?”

Before he officially takes office, he must know when the DDL of the task is.

“The first issue is in the third quarter of 2001. It is planned to be between the end of June and the end of August. Of course, the specific time depends on your work arrangement. If the manuscript request process goes smoothly, it is not impossible to do it earlier..."

With the gradual promotion of electronic journals, the publication dates of major publishing houses are getting earlier and earlier.

Many monthly magazines are even released 4-6 months in advance.

In comparison, JCAS only published the third quarter in June, which is already relatively slow.

“Also, Professor Chang.”

Seeing that Chang Haonan did not reply immediately, after a slight pause, Yuan Xiangya continued:

“After all, we are a brand-new journal, and this first issue… we have to make sure it gets off to a good start, so see if you can…”

Today, Chang Haonan's name is still well-known in the international academic community.

If you just serve as editor-in-chief, it may not attract much attention.

But if a year later, he publishes an article as the first author, it will definitely be big news.

“Is this...”

Chang Haonan wanted to say that he needed to think about what to write before replying, but at this time, out of the corner of his eye, he saw the several pieces of draft paper on the table that had just been filled with his writing.

“Okay, I happen to have a fairly mature idea on hand, and it should be completed soon.”

He replied decisively.

Yuan Xiangya was overjoyed:

“Then we will wait for the good news from Professor Chang...”

After hanging up the phone, Chang Haonan took off his coat and sat back on the chair.

He first called Yao Mengna and asked her to bring him a dinner.

　　Next, open a new Word document and enter the title of the paper you just thought of:

Aconservativelevelsetmethodfortwophaseflow (a conservative level set method for two-phase flow).
