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 quite a bit.

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

Although there is also a saying and phenomenon of pursuing hot research directions in academia, unless it is a field like biology or materials that produces relatively short and fast results, the significance is really limited.

So overall it's 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 still send emails to this mailbox.

In fact, this includes Perelman himself.

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

In addition to the usual exchange of some 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, so it is not a big problem to be a listener and admirer.

All in all, they looked like they had been friends for many years.

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

Of course, not all emails are such life-like content.

Mariam 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.

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

However, he later vaguely remembered 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.

Just because Mirzakhani can make outstanding achievements in the fields of hyperbolic geometry and symplectic geometry does not mean that she can reach the same heights in another direction.

But no matter what.

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

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

This issue is really his area of ​​expertise——

Not only topology, but also 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, but from a theoretical mathematical perspective, this method still has the problem of non-conservation...]

At first, 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 I 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 to order cumin duck legs for dinner.

The phone on his desk suddenly rang.

It's the white one.

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

Outside calls.

Usually 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 over there.

"Dean Yuan?"

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

During the period 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.

"Is your journal already ready?"

"Professor Chang's words are obvious, right?"

There was an unstoppable smile in Yuan Xiangya's words:

"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 point.

Mainly because he was really hungry.

There is no large-scale takeout industry these days. If you find someone to bring food, it will basically be cold when you 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. However, 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 Department..."

"..."

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 very high independent authority for JCAS journals.

Plus Chang Haonan, the "externally hired" editor-in-chief.

It can be considered 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 officially taking office, he must know when the DDL of the task is.

"The first issue is in the third quarter of 2001, and the plan is to be between the end of June and the end of August. Of course, the specific time depends on your work schedule. If the appointment process goes smoothly, then 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 contrast, 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 ensure a good start, so see if you can..."

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

If you were just serving as editor-in-chief, it might not attract much attention.

But if he publishes an article as the first author after a year, 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 scraps of 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 just wait for Professor Chang's good news..."

"..."

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.

Immediately afterwards, I opened a new Word document and entered the title of the paper I just thought of:

A conservative level set method for two phase flow.
