After writing a paper for two days in the dormitory, Xu Chuan originally wanted to attend a meeting in the Department of Astronomy on the third day, but he called Dean Qiu Chen of the Academy of Astronomy and asked, and only then did he find out that the meeting had been delayed for a while.

Moreover, after receiving the materials submitted by Nanyang University, the China Astronomical Association took the initiative to directly turn this meeting from an internal meeting of the Nanyang University School of Astronomy and Space Science into a large-scale national astronomical conference. At that time, some major and senior institutions in the domestic astronomical community will come to attend the meeting.

First, we will study and discuss the impact of companions in the Betelgester tetrahydrogen cladding on Betelgester titanium together, and second, we will learn the xu-weyl-berry theorem to accurately calculate the parameter information of distant celestial bodies.

A more accurate calculation method than before is definitely worth learning for the astronomy world.

The person who invented this method is now at Nanjing University. He asked him to come on stage to give a report and explanation. Everyone can listen to it. Can you understand it? But the learning attitude must be put forward.

As for Nanjing University, I must be happy.

Organizing such large-scale conferences is crucial to enhancing the influence of Nanjing University, which can be greatly enhanced by the School of Astronomy and Space Sciences, or Nanjing University itself.

...........

A week passed quickly. After writing the two papers, Xu Chuan cast out the method of accurately calculating the parameter information of distant celestial bodies.

As for the journals submitted, he chose neither the mathematics journal nor the astronomical journal, but chose the astrophysics journal "Annual Review of Astronomy and Astrophysics".

The English name of this journal is "anronomy and astrophysics". It was founded in 1963 and was published by the publisher of annual reviews inc. in the United States. Their acceptances cover the entire fields of geologic astronomy-astronomy and astrophysics.

This journal has a huge academic influence in the field of astrophysics industry. It is a top journal and an international first-class journal. It has a high level of attention and professionalism. It requires high innovation in original articles and is top-notch.

But again, its impact factor is terrible.

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

Although the impact factors of the two top 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, the sub-publication of Nature's Astronomy, "Nature" has only about 10 points of influence.

Compared with the Annual Review of Astronomy and Astrophysics, it is one level lower.

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

The Annual Review of Astronomy and Astrophysics only contains papers on astronomy and astrophysics.

In Xu Chuan's view, although the method of xu-weyl-berry theorem to accurately calculate the parameter information of distant celestial bodies is extended from mathematics, its service object is not mathematics, but astrophysics.

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

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

At least astrophysics is related to physics, and the dual cultivation of matter and numbers is achieved. In order to balance it, Xu Chuan chose to submit it to a top journal of astrophysics.

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

Of course, while investing the paper to the "Annual Review of Astronomy and Astrophysics", Xu Chuan also threw it on the arxiv preprint server for reference, research and communication among other scholars.

.........

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 a lot of sensation.

As the world's largest, oldest and most popular preprint server, arxiv has articles from multiple fields, such as physics, mathematics, computer science and statistics, etc., and astrophysics is naturally among them.

Whether it is a student, a professor, or a research institute or laboratory outside the academic community, or perhaps the most cutting-edge knowledge in the scientific community is a must-have.

There are generally two ways to acquire cutting-edge knowledge. One is to order journals that require knowledge.

For example, "nature" and "sce".

However, ordering these journals is not cheap. Take "nature" as an example. It usually costs 20 meters to read a natures, which is equivalent to more than 100 yuan.

Whether this price is expensive or not, it is not cheap. It is not a problem to buy a site lise or apply for a reimbursement in most wealthy companies and awesome schools.

However, it is very problematic for individuals with interest in scientific research or schools in backward areas.

In countries like Malawi and Central Africa, in 2016, the GDP per capita was only $400 in the official data (about 20 articles). How do you let others play? Should you let knowledge concentrate in the hands of a few people like wealth?

In addition, it is not only schools in these backward areas, but also schools and research institutions in developed countries, as the number of various scientific research documents increases, it is becoming increasingly difficult to pay for the fees generated by subscribing to journals.

Not to mention the others, just take China as an example.

In China, the most famous one is CNKI. Although it is not a journal, it is even better than journals in terms of knowledge charges.

This is probably the pain of every college student and graduate student when writing his graduation thesis.

Nowadays, the price for plagiarism checking for graduation thesis of domestic students is about 200 yuan if the characters are within characters, while the price for plagiarism checking system for master's and doctoral thesis is about 350 yuan if the characters are within characters.

This price can be said to be quite expensive.

Moreover, when a college student writes a graduation thesis, he may check the pound more than once. Sometimes, if there are too many, you can plunder thousands of yuan from a college student at one graduation.

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

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

Just as people have always wanted the Internet to be neutral, that is, Internet service providers such as telecom operators, cable companies, etc. should treat all traffic through their networks equally. People do not want money to block the spread of knowledge.

Therefore, the scientific community has the ‘Budapest Declaration’, which calls for open access to all new peer-reviewed research and to promote it to all disciplines and countries.

On this basis, preprint websites such as arxiv, biorxiv, chemrxiv, and the winner have developed quite rapidly and have received support from many scientific researchers.

As these preprint websites become larger and larger, there are more and more papers and ideas on them, many university professors and researchers like to browse these preprint websites.

In this way, we can gain new inspiration and knowledge from above, or keep a close eye on the progress of other people's research projects.

These preprint websites can basically be set up for content tracking that are of interest or are interested in content tracking.

For example, in the physics world, you can set up a tag of high-energy physics, or particle physics, or condensed matter physics. If someone discovers these tags on the website, the website will push it to you as soon as possible.

No, if there are graduate students or professors who are concerned about the astrophysics industry, the researchers will receive a push from the website as soon as possible.

"A Method for Accurate Calculation of Parameter Information of Universe 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 scientific researchers who have paid attention to this push.

In the scientific community, whether in mathematics, physics, or subjects such as materials, biology, and astronomy, the emergence of calculation methods is often far more difficult than results.

In the astrophysical world, the method of calculating the parameter information of cosmic celestial bodies has not been updated for a long time.

Whether it is the universal gravitational formula, the Hero diagram, the luminosity calculation, the Lingxing World calculation, the radial velocity method, they are actually things from more than ten years ago or even decades ago in the last century.

These methods have actually had considerable flaws since their development.

The biggest problem is naturally that the calculated data is inaccurate.

Take Betelgeuse, one of the most popular observation targets in the astronomical world, as of now, the definition of its mass in the astronomical community has a large deviation from ten times the mass of the sun and a span of twenty times the mass of the sun.

Although there are reasons for inadequate observation methods, 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 of parameter 4.

Now a brand new method is emerging, even if it is thrown on websites like arxiv where most papers and ideas are dross, it is enough to attract attention.

However, when these astronomers who were full of expectations downloaded and opened the paper, they were all stunned.

What is this paper written?

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

The final conclusion is certainly not written randomly?

...........

Hobby Space website forum, where there are a large number of astronomical enthusiasts and astronomical workers gather.

The paper that Xu Chuan threw on arxiv caused heated discussion here.

[Did someone read the paper "A Method for Accurate Calculation of Parameter Information of Universes using the xu-weyl-berry Theorem." on Arxiv?]

[I read it, but I can't understand it at all. The mathematics inside is really too profound.]

[I seriously suspect that a mathematician deliberately disgusted us. Maybe all the calculations inside were wrong. Finally, I wrote a number on it like a decent one.]

[That's not. I have read this paper, and I know the author. The 18-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 this, but as you said, these calculation processes are really too difficult to understand.]

[If it is true, then we should have a more accurate calculation method in the future, but didn’t he learn mathematics? Why is this paper not included in the mathematics classification? Instead, it is thrown into the astronomical and physical classification.]

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

[But the entire paper is full of mathematical proof and calculation. I am afraid no one in the entire astronomical world can understand it. Isn’t it better to put it in mathematical classification?]
