After writing his thesis in the dormitory for two days, Xu Chuan wanted to attend the meeting of the astronomy department on the third day, but he called Qiu Chen, the dean of the Astronomical Academy, and learned that the meeting had been delayed for some time.

Moreover, after receiving the materials submitted by NTU, the Chinese Astronomical Society took the initiative to turn this conference from the internal meeting of the School of Astronomy and Space Science of NTU directly into a large-scale national astronomical conference, and some relevant institutions in the domestic astronomical community will come to participate in the meeting.

The first is to study and discuss the influence of companion stars in Betelgeuse's tetrahydrogen envelope on Betelgeuse, and the second is to learn the method of the Xu-Weyl-Berry theorem to accurately calculate the parameter information of distant celestial bodies.

A more accurate method of calculation than before is certainly worth learning for the astronomical community.

The person who invented this method is now at NTU, and he is invited to come to the stage to give a report and explanation, and everyone can listen to it, and whether they can understand it or not is another matter, but the posture of learning must be put on a posture.

As for NTU, it must be happy.

Organizing such large-scale conferences is crucial to enhancing NTU's impact, both for the School of Astronomy and Space Sciences, and for NTU itself.

........

A week passed quickly, and Xu Chuan wrote the two papers and threw out the method of accurately calculating the parameters of distant celestial objects according to the Xu-Weyl-Berry theorem.

As for the journals to which he submitted, he chose neither mathematics nor astronomy, but the astrophysical journal Annual Review of Astronomy and Astrophysics.

The journal was founded in 1963 and published by Annual Reviews Inc. publisher in the United States.

This journal has a huge academic influence in the field of astrophysics industry, belongs to the top journal, the world's first-class journal, the attention and professionalism are very high, the original articles are required to be highly innovative, and the difficulty of passing the review is top.

But again, its impact factor is frighteningly high.

In 2016, that is, this year, its impact factor index was 34.226, which is outrageously high.

Although the impact factor of the two top academic journals in the academic world, "Nature" and "SCE", can also be as high as 40, correspondingly, their sub-journals related to astronomy are not so exaggerated.

For example, Nature Astronomy, a sub-journal of Nature, has only about 10 points of influence.

Compared to the Annual Review of Astronomy and Astrophysics, it is a level lower.

Of course, this is also related to the wide range of papers included in Nature, from biology to medicine, to natural materials, natural astronomy, etc., the range of included papers is quite wide, and a large number of sub-journals have also been derived.

The Annual Review of Astronomy and Astrophysics, on the other hand, only includes papers on astronomy and astrophysics.

In Xu Chuan's view, although the method of accurately calculating the parameter information of distant celestial bodies is extended from mathematics, the object of its service is not mathematics, but astrophysics.

So it would be appropriate to vote for the Annual Review of Astronomy and Astrophysics.

Of course, there is no problem with it being submitted to a mathematics journal, but if this paper is submitted to a mathematics journal, he will be completely crushed by mathematics in physics now.

In order to balance it, Xu Chuan chose to submit it to the top journal of astrophysics.

Moreover, with the status of the Annual Review of Astronomy and Astrophysics in the astrophysical community, there is no need to worry about sinking this paper.

Of course, at the same time that the paper was submitted to the Annual Review of Astronomy and Astrophysics, Xu Chuan also threw it on the ARXIV preprint server for other scholars' reference research and exchange.

.........

After the paper was submitted, Xu Chuan took a short break, but when he was resting, the paper he threw on the arxiv preprint server caused quite a stir.

As the largest, oldest and most popular preprint server in the world, arxiv has articles from a variety of fields, such as physics, mathematics, computer science, and statistics, and astrophysics is also included.

Whether it is a student, a professor, or a research institute or laboratory outside of academia, perhaps the most cutting-edge knowledge in the current scientific community is necessary.

Generally speaking, there are two ways to obtain the most cutting-edge knowledge, one is to subscribe to the journals that need the corresponding knowledge.

For example, "Nature" and "SCE".

But ordering these journals is not cheap, take "Nature" as an example, to read a piece of Nature generally costs 20 yuan, which is equivalent to more than 100 yuan.

This price is not expensive, it is not cheap, and it is not a problem to buy a site lise or reimburse it in most rich companies and schools.

But for individuals who are interested in scientific research, or for schools in backward areas, it is very problematic.

In countries like Malawi and Central Africa, in 2016, the per capita GDP in official data was only 400 US dollars (read about 20 articles). Should knowledge be concentrated in the hands of a few like wealth?

In addition, it is becoming more and more difficult to pay for subscribing to journals, not only in schools in these backward regions, but also in developed countries, as the volume of various scientific research literature increases.

Don't talk about the rest, just take Huaguo as an example.

In China, the most famous is CNKI, although it is not a journal, but it is better than journals in terms of knowledge fees.

This is probably the pain that every college student and graduate student has when writing their graduation thesis.

Nowadays, the price of domestic students' graduation theses is about 200 yuan, and the price is about 200 yuan, while the price of the master's and doctoral thesis is about 350 yuan within 200,000 words.

This price can be said to be quite expensive.

Moreover, when a college student writes a graduation thesis, he may check the plagiarism more than once, and sometimes if there are more, a graduation CNKI can scavenge thousands of dollars from a college student.

Not to mention master's and doctoral students, as well as professors at universities.

Although it is normal to pay for knowledge, the fees of knowledge websites such as CNKI and academic journals are rising day by day, resulting in many schools and scientific research institutions being unable to keep up with the pace of development of academic journals.

It's as if people have always wanted the Internet to be neutral, i.e., that Internet service providers such as telecom operators and cable companies should treat all traffic through their networks equally. And people don't want money to stop the spread of knowledge.

Hence the 'Budapest Declaration' of the scientific community, which calls for open access to all new peer-reviewed research and its promotion to all disciplines and countries.

On this basis, the preprint websites such as Arxiv, Biorxiv, Chemrxiv, and The Winnower have developed quite rapidly and have been supported by many researchers.

As these preprint sites grow in size and contain more papers and ideas, many university professors and researchers like to browse these preprint sites.

This is a way to gain new inspiration and knowledge from above, or to keep an eye on the progress of other people's research projects.

And these pre-printed websites can basically be set to be interested in, or follow content tracking.

For example, in the physics world, you can set a label for high-energy physics, or particle physics, or condensed matter physics, and if someone finds the content of these tags on the website, then the website will push it to you as soon as possible.

No, graduate students, professors, and researchers who are concerned about the astrophysics community received the website push as soon as possible.

"A Method for Accurately Calculating the Parameter Information of Cosmic Celestial Bodies Using the Xu-Weyl-Berry Theorem." 》

The title of Xu Chuan's paper has always been simple, but this simple title has attracted the attention of most of the researchers who have paid attention to this push.

In the world of science, whether in mathematics, physics, materials, biology, astronomy, etc., the emergence of computational methods is often far more difficult than the results.

In the field of astrophysics, the method of calculating the parameters of cosmic celestial bodies has not been updated for a long, long time.

Whether it is the gravitational formula, or the Herrault diagram, the luminosity calculation, or the transit calculation, or the radial velocity method, these are actually things more than ten years ago or even decades ago in the last century.

These methods have developed to the present, in fact, there are quite a few flaws.

The biggest problem is, of course, that the calculated data is inaccurate.

As far as Betelgeuse, one of the hottest observation targets in the astronomical community, is concerned, up to now, the definition of its mass in the astronomical community has deviated so much that it can start from 10 times the mass of the sun and span to 20 times the mass of the sun.

Although there are reasons why the observation methods are not in place, the bigger problem is that the previous calculation methods can only be accurate to such a value.

Astronomers can no longer use the observed data to further calculate the data for parameter four.

Now a whole new approach has emerged, and even if it is thrown on a website like arxiv, where most of the papers and ideas are, it is enough to attract attention.

But when these expectant astronomers downloaded and opened the paper, they were dumbfounded.

What is this paper about?

The calculation process in the middle is all the devil's symbol, right?

The final conclusion, are you sure that it was not written randomly?

........

The Hobby Space website forum is home to a large number of astronomy enthusiasts and astronomers.

The paper thrown by Xu Chuan on ARXIV caused a heated discussion here.

[Someone read Arxiv's "A Method for Accurately Calculating the Parameter Information of Cosmic Celestial Bodies Using the Xu-Weyl-Berry Theorem."] This paper? 】

[I read it, but I can't understand it at all, the math in it is too profound.] 】

[I seriously suspect that some mathematician is deliberately trying to disgust us, maybe all the calculations in it are wrong, and finally write a random value on it.] 】

[That's not it, I've also read this paper, the author I know, the eighteen-year-old super mathematical genius who proved the Weyl-Berry conjecture in Princeton some time ago, the xu-Weyl-Berry theorem can indeed be used to calculate the parameters of celestial bodies, I can guarantee that, but as you said, these calculations are too difficult to understand. 】

[If it's true, then we should have a more accurate calculation method in the future, but didn't he study mathematics?] Why is this paper not placed under the Mathematics category? Instead, it was dropped into the astrophysical classification. 】

[Maybe the object of this paper is not mathematics, but celestial objects in the universe?] 】

[But the whole paper is full of mathematical proofs and calculations, I'm afraid that no one in the entire astronomical community can understand it, wouldn't it be better to put it under mathematical classification?] 】

Who knows.......
