Great Country Academician

Holding a cup of tea, Xu Chuan flipped through the paper in his hand.

Although it is a pity that this paper did not make a new breakthrough in the non-trivial zero distribution of the Riemann hypothesis, its research ideas and directions are indeed novel.

Using the exact form of the phase function tlogn implied by the Dirichlet function, a key phase matrix n^(it)=e^(itlogn) is raised to the sixth power.

The stationary phase method is not used to simplify the Fourier integral. The problem is divided into three cases of small, medium and large additive energy E(W), and each different case is handled by changing the parameters.

Xu Chuan did not think about this way of handling, which has a great inspiration for his study of mathematics, especially analytic number theory.

"However, the style of this paper seems to be somewhat familiar, especially in the application of sieve method, which is very interesting."

Flipping through the paper in his hand, Xu Chuan's eyes were full of interest.

I don't know if it's his illusion, he always feels that the mathematical method used in this paper is a bit familiar.

It should not be an acquaintance, but he must have read this scholar's paper carefully.

After all, for scholars like them who have already stood at the top of the academic world, most of them have their own areas of expertise and habitual methods for dealing with a certain problem.

In addition, there are some unique styles in the choice of words, sentences, style, etc. when writing papers.

Although the review invitation of "New Advances in Mathematics" is double-blind, in principle, the reviewers cannot see the names of the contributors, and the contributors do not know who is reviewing their papers.

But if you want to determine who submitted the manuscript, there are actually many ways.

Whether it is to find an acquaintance to find out who is currently studying the difficult problems in related fields, or to find a preprint website such as Arxiv to see if there are any corresponding papers.

After all, in recent years, perhaps influenced by him. Many scholars, especially in the fields of mathematics and physics, have the habit of posting their papers on Arxiv or other preprint websites before formally submitting them.

With some curiosity, Xu Chuan shouted: "Xiao Ling, help me search arxiv and similar preprint sites to see if there is a paper called "New Large Value Estimation Based on Dirichlet Polynomials" or similar papers on them."

"Received!"

"Trying to find it~, hahaha (ov)ノ"

In the lower right corner of the display, a chat box that was originally hidden popped up, and the text on it jumped.

Soon, a new reply jumped.

"Found it, Master! There is an identical paper on the Arxiv preprint site."

"So fast?"

Xu Chuan asked in surprise. It only took five or six seconds to find it?

"Of course, I'm awesome, right? Master!"

"Awesome, you're the best."

Xu Chuan smiled and praised casually, and then asked: "Who is the author of the paper?"

The pop-up box jumped, and Xiao Ling's reply came quickly.

"Shy face covering.JPG, the authors of the paper are Professor James Maynard from Oxford University in the UK and Professor Larry Guth from the Massachusetts Institute of Technology in the United States."

Looking at the names in the chat box, Xu Chuan suddenly understood.

No wonder he felt that the paper was familiar but not familiar, it turned out to be Professor Maynard.

James Maynard, a scholar who was supposed to win the Fields Medal at the 2018 International Congress of Mathematicians, was squeezed out of that session because of his appearance.

However, at the 2022 National Congress of Mathematicians, he successfully won the Fields Medal that originally belonged to him.

No wonder he felt that the style of the paper was familiar.

Professor Maynard's research in the field of analytic number theory, especially in the field of sieve method and prime numbers is quite profound.

Like the famous Peter Schultz, James Maynard is also a genius who was born in his youth.

As early as his doctoral stage, he developed a new sieve method to detect prime numbers in bounded length intervals. And later used this method to solve Paul Erdős conjecture about the large gap between prime numbers.

I have to say, this world is really small.

The paper he reviewed was actually from an acquaintance.

Looking at the name that popped up in the chat box, Xu Chuan chuckled and shook his head.

Unexpectedly, Maynard also jumped into the super pit of the Riemann hypothesis.

But it is normal to think about it. After all, he is a top scholar in analytic number theory, and the Riemann hypothesis is undoubtedly the biggest problem in this field. It is normal to focus on this.

After all, four of the seven millennium problems have been solved, and the remaining three are even more precious.

Just as Xu Chuan was about to search for Maynard's recently published papers, the office was suddenly knocked a few times, and a person who was somewhat unexpected walked in from outside.

"Haha, Academician Xu, long time no see."

Hearing this familiar voice, Xu Chuan looked up, a little surprised, and smiled and said: "Long time no see, Gao Hall."

The person who came was Gao Hongming, the former director of the Strategic Planning Department of the Science and Technology Department, who should have been promoted now.

The two had worked together for several years. When he returned to China to carry out the "Nuclear Energy β Radiation Energy Aggregation and Conversion into Electric Energy Mechanism Project" and the "Controlled Nuclear Fusion Project", it was Gao Hongming who cooperated with him.

After the controlled nuclear fusion project was completed, Wen Yuanhang took over.

"Yes, it's been almost two years since we last met." Gao Hongming said with a smile: "The last time we met was when the Haixi aircraft carrier was launched."

Xu Chuan called out to the assistant room outside, asked Tang Ran to help make two cups of tea, and said with a smile: "There shouldn't be any big problems with the operation of the Haixi now, right?"

This is an aircraft carrier that was converted from conventional power to nuclear fusion power. The transformation project is not big or small.

However, this is the first time that a fusion reactor has been installed on a ship.

Gao Hongming said with a smile: "Problem? What problem can there be? The Haixi is showing off now. It also sailed to the Mediterranean some time ago."

"Mediterranean? What are you doing there?" Xu Chuan asked curiously.

Gao Hongming smiled and said, "Nominally, it is to escort our shipping, but it's been a bit chaotic there recently, you know."

Xu Chuan suddenly nodded, smiled and nodded, saying, "I understand."

After chatting for a while and drinking a cup of tea, Gao Hongming saw that the time was almost up, so he didn't waste any more time and smiled and said, "This time I came here mainly for project work."

As he said that, he took out a document from his briefcase and handed it over.

Xu Chuan took it and took a look at it, with a hint of surprise in his eyes: "It was decided so quickly?"

The document Gao Hongming handed him was nothing else, but the project he wrote a letter to send some time ago.

The instructions and plans for the "Lunar Orbit Mass Projector Project" and other materials.

Gao Hongming smiled and said, "Yes, after high-level discussions, the lunar orbital mass projector project was officially approved. It is directly controlled by the State Council, led by the Department of Science and Technology, and developed and built by the Xinghai Research Institute. I am responsible for coordinating related work, which is also the main purpose of my rushing here this time."

Xu Chuan flipped through the information in his hand and smiled and said, "I didn't expect to be able to cooperate with the Gao Department again."

Gao Hongming smiled and said, "I am looking forward to it too."

After chatting about the lunar orbital mass projector project for a while, Gao Hongming remembered another thing and found a document from his briefcase and handed it over.

"By the way, Academician Xu, I have another thing to trouble you this time. Please take a look at this document first."

Hearing this, Xu Chuan took the document with some curiosity, and the title caught his eyes.

"Feasibility Study of Ultra-High-Speed ​​Precision Strike Electromagnetic Railgun Technology"

After pausing for a while on the title, Xu Chuan raised his head, looked at Gao Hongming, and asked with a smile: "You don't want me to do this, do you?"

Gao Hongming smiled and said: "No, no, how could it be possible."

"This is something made by the Naval Equipment Department and the Academy of Sciences. However, the higher-ups are not very sure about the feasibility of this project, so they asked me to bring it here, and I would like to ask you to take a look at it."

Xu Chuan glanced at him, sighed and said: "Don't beat around the bush, just tell me, what problems have you encountered that you want me to help you solve?"

Hearing this, Gao Hongming smiled awkwardly, touched his head and said embarrassedly: "Then I'll tell you straight."

Thinking for a while, he continued: "Using electromagnetic rails or electromagnetic coils to complete the initial speed increase of kinetic weapons can greatly improve The speed of missiles or weapons can effectively enhance national defense. "

"As for the technology in this document, the experts of the Naval Equipment Department and the Academy of Sciences have almost demonstrated it, and the feasibility is still relatively large."

"However, I heard from relevant experts that when the electromagnetic track or electromagnetic coil is running, because it is at an extremely high speed, the aviation structure will be surrounded by a plasma shell, and the plasma shell is composed of atomic nuclei and electrons in a separated state, with high conductivity, so it will interfere with electromagnetic transmission. This will cause great damage to related control, guidance, communication and other equipment, affecting normal operation.

Gao Hongming worked hard to "recite" a whole paragraph of the problem that the expert from the Science and Technology Department told him. He was so embarrassed that he took several deep breaths before he recovered, and then said:

"I am not very clear about the specific situation and problems. After all, I am not an expert in this area. But it is written in this report. Why don't you take a look first? "

Xu Chuan's eyes moved. He didn't even need to look at the document when Gao Hongming said these words. He knew what the problem was.

To put it simply, it was the 'guidance problem' and 'orbital ablation problem' that occurred when the electromagnetic gun was launched.

Both were caused by the magnetic field, and they were also the two biggest problems in the practical application of the electromagnetic railgun.

As for the research on magnetic fields, he said he was second in China, and I'm afraid no one dared to claim to be the first.
