Academy.

Superconducting Physics Laboratory, Office of Nuclear Magnetic Resonance Research.

Several academicians and researchers are sitting in the office talking about the latest experiments, and they are doing a theoretical research project on superconductivity, that is, using nuclear magnetic resonance to study the principle and mechanism of superconductivity.

This research is the basic theoretical research of superconductivity.

Because the latest experiment did not meet expectations, when several people talked about it, they were not in a good mood, but in fact, it was not expected to be expected.

The theoretical mechanism is already very difficult to study, and the project has been going on for ten years, and there has been no progress for a long time.

Fortunately, the country attaches great importance to cutting-edge superconductivity research, and the project funds are continuously supplied.

Academician Zhang Zhongxian, who is 60 years old, is the main leader of the project and a well-known superconductivity expert in China, and he encouraged, "This experiment did not meet expectations, but it can be regarded as laying the foundation for the next experiment, so don't worry too much." ”

Zhou Pengcheng, a researcher next to him, shook his head and sighed, "We haven't achieved results for a long time, and I feel that the theoretical research on superconductivity has reached a bottleneck." ”

The others were silent.

It's the truth.

Superconductivity refers to the state in which the resistance of a conductor at a certain temperature is zero.

The phenomenon of superconductivity has been discovered for hundreds of years, and superconductivity technology has also appeared for decades, and has always been regarded as a cutting-edge technology, but due to the limitations of use, it has not been able to be applied on a large scale.

Now the superconducting industry is studying how to break through the technical bottleneck, and theoretical support is very important.

Many people in the industry believe that there is no higher-level breakthrough in theory, and it is difficult to apply technology on a large scale.

theoretical research, which limits the development of technology.

Because of this, various countries continue to invest in the theoretical mechanism of superconductivity.

Another researcher, Xiang Qiansheng of the Institute of Electrical Engineering of the Academy of Sciences, said, "It is precisely because of this that we will support research in various directions related to superconductivity. ”

He shook his head as he spoke, obviously not optimistic.

The theory of 'alternating gravity' has been around for 30 years, and it was only 20 years ago that experimental discoveries were reported.

As the superconductivity laboratory of the Academy of Sciences with the most powerful level in China, they naturally did related research, but later found that they could not do it if they wanted to replicate the experiment.

On this project, they spent 20 million dollars, but they didn't even find anything.

Later, I had to give up.

They are the State Key Laboratory under the Academy of Sciences, with academicians and researchers from the Academy of Sciences, each of whom can be said to be experts in superconductivity, and they have spent 20 million yuan to find nothing.

The physics laboratory of Xihai University has applied for a grant of 200 or 3 million, what results do you want to achieve?

How can it be!

Zhou Pengcheng also followed, "This kind of project is obviously looking for a gimmick to apply for some funding, everyone knows it, and it is impossible to find it." ”

Zhang Zhongxian said, "This also shows that the country attaches great importance to this aspect, superconductivity research is too critical, which may become a key technology for future competition, and theoretical research is the top priority." ”

Several people began to shake their heads and sigh again.

Regardless of other small labs, their research is indeed stuck in a bottleneck, and it is difficult to make a breakthrough in a certain direction.

This bottleneck even makes them wonder how to design experiments and continue their research.

Of course, for the research on the theoretical mechanism of superconductivity, it is normal to fall into a bottleneck and have no results, and it is necessary to constantly summarize and study in order to find the right direction.

……

Physics Laboratory, Seohai University.

Wang Hao said that if he wants to participate in the experiment, he will naturally really participate.

The next day he went to the physics lab, where he worked with others to prepare new experiments and learned more about all aspects of the experiments.

Then he found that the experimental design was very crude.

This is mainly due to the fact that there is very little known information about the content, and they can only try to reproduce the content of the data.

It's hard to say whether the information is true or not.

Wang Hao knew less about the experiment, he just watched to understand some of the content, and did not participate in the preparation of the experiment.

In addition, the preparation of the experiment is not completed at once, because some materials require special approval, and some of them also require a certain amount of time to purchase.

"At least a week or more." He Yi estimated the time, "The last experiment consumed too many materials, and we need to buy new materials. ”

Wang Hao asked, "Is there any difference between this experiment and the last one?" ”

"This ......"

He Yi thought hesitantly, "I discussed it with Professor Xiao and felt that a new conductor layout method should be adopted. ”

"Is it just a conductor layout...... Wang Hao sounded a little unreliable.

He Yi also knew that it was a little unreliable, but he had no other way, because there was too little relevant information, so he could only try to design it again and again.

Wang Hao thought about it and said, "In this way, don't rush to prepare the materials first, the funds are limited, let's study it as a whole first, and then make preparations after thinking about how to conduct the experiment." ”

"It's fine." He Yi nodded.

This experiment already has the experience of the last time, so there is no need to prepare for that long, but because the last time it failed, it is difficult to say whether the experience is useful or not.

He Yi, Xiao Xinyu and Wang Hao discussed it and decided to summarize the last experiment again.

It is good to prepare the new experiment slowly, and with the summary of the previous experiment, we will study the new experimental method, and then prepare the experiment after everything has been thought out.

The Physics Laboratory held an internal wrap-up meeting.

The main purpose of the meeting is to summarize the last experiment, that is, to analyze why the experiment failed.

Of course, there are many possible causes.

Wang Hao also participated in the meeting, he thought that he would just listen to it, but soon found that the meeting was very embarrassing, and almost no one else spoke, it was He Yi and Xiao Xinyu who were talking.

Gravity is a phenomenon that may and may not exist, and international reports are only a few words, and very little information can be found.

Although they have conducted relevant research, the progress of the research has been minimal, and at most it can support the writing of a few papers, but it is only an experimental paper, because there is no successful replication of the experiment, and there is even less to summarize.

Yan Jing was trusted by He Yi, but she only talked about some experimental data, and she couldn't enter the theoretical content from the experimental data.

In the end, He Yi simply asked Wang Hao, "Professor Wang, can you say a few words?" ”

Everyone looked at Wang Hao.

Wang Hao thought for a while and said, "I am a layman in physics research, and the research of superconductivity is even more layman. ”

He continued, "But I've been reading a lot of relevant materials lately, and I can be regarded as having a little personal understanding of this research. ”

"I think it's like this kind of research, if you don't have a good idea, you analyze it from the mechanism of the theory?" His tone was a little uncertain, and he looked at He Yi with doubts.

He Yi didn't know whether to nod or shake his head. From this sentence, Wang Hao is indeed a layman.

The study of physics is all about discovering phenomena first and then analyzing the principles.

Because of this, they are obsessed with replicating experiments, and only by replicating experiments can they analyze the data and find out the mechanism and principles contained in it.

Now Wang Hao said to analyze the principle first, how can it be analyzed?

He Yi just glanced at Wang Hao and didn't show his attitude.

Wang Hao continued, "In terms of theoretical mechanism, we must first study the theoretical mechanism of superconductivity. ”

"More than ten years ago, there was a theory called degenerate superconductivity, which you should all know."

"According to this theory, the microscopic physical mechanism of superconductivity has been discovered, that is, the relative separation of 'superconducting free electron gas' and 'degenerate positive ion lattice' in the superconducting state, and the two do not collide in any way."

"From this principle, the possibility of the existence of antigravity is related to the ion lattice formed by the superconducting state."

This is based on a personal judgment of the study, but the system directly feeds back the results.

Because of this, Wang Hao will discuss from the theoretical point of view.

"Let's assume that it is directly related to the ion lattice." After receiving the feedback from the system, Wang Hao immediately became confident, "So how can the phenomenon of 'alternating gravity' be generated?" ”

"Is there a possibility that this is due to the spin of the ion lattice in some arrangement?"

"If we follow this principle, how can the ion lattice be arranged to produce a special field force?"

"Maybe it's not a field force, but a gravitational block, or maybe it's a special case of a mixture of magnetic and electric fields? These are all possible. ”

"We analyze them in turn to get some kind of hypothesis to test. This is the method of microphysics research. ”

The last sentence made everyone nod.

In the study of the mechanism of superconductivity, it is almost always the discovery of new physical phenomena, and then the mechanism is deduced from the phenomena.

However, the study of microphysics starts from theory, because there are many microscopic physical phenomena that cannot be directly explained, so theoretical physics needs to provide support, and theoretical physics can be constructed to deduce other problems.

For example, the Higgs particle and neutrino are all theories that have been discovered in experiments.

Wang Hao said at the beginning that he would study the theoretical mechanism first, and everyone present would definitely disagree, but if he just assumed a theory and then designed experiments based on theoretical derivation, to some extent, there was some truth.

Wang Hao's speech was to ask some questions, and then make a detailed analysis of each part.

In this way, it takes more than an hour to talk about it.

The meeting was suddenly lively.

Because they just make assumptions and imagine, many people began to speak enthusiastically and boldly express their ideas, and the speech of 'teaching' quickly became 'scientific research', the difference is that one person speaks and studies with many people.

Wang Hao found that he also had more inspiration.

This inspiration is not reflected in the task, because it is not directly related to the study of annihilation, but only in his thoughts and judgments.

The meeting lasted more than two hours.

Wang Hao concluded, "Therefore, a more likely judgment is that the occurrence of AC gravity phenomenon is related to the spin of the ion lattice inside the material in the superconducting state. ”

"The arrangement may be parallel or vertically superimposed, and we can design experiments based on this inference."

"I guess the next step is to know how to do the experiment, right?"

He looked at He Yi.

He Yi also participated in the discussion, but he didn't really say a few words, he was just very surprised.

Originally, he just asked Wang Hao to talk about his thoughts, but he guided the meeting into a 'theoretical seminar', and then everyone spoke enthusiastically, and really studied a 'possible theory'.

This one......

Although I was personally involved, it was a little strange to think about it.

Why wasn't that the case at the meeting he chaired?

That's not right!

"I was supposed to preside over this meeting." He Yi tugged at the corners of his mouth vigorously, and he found that he should let Wang Hao preside over the meeting in the future.

Although his research field is superconducting physics, it seems that Wang Hao is more professional than him in the study of theoretical mechanisms.

……

Wang Hao left after attending the meeting.

He also gained a lot, just the knowledge and ideas in his head, as well as a deeper understanding of superconductivity, made him feel that he benefited a lot.

In addition, he found himself very good at leading scientific research projects.

Because of "The Gift of Teaching" and "The Gift of Scientific Research", he can easily put the discussion content on the right track, and it is very helpful to analyze the experiment or the theoretical mechanism.

Then it will be very efficient to do project research naturally.

"Shall I apply for a big project as well?" Wang Hao suddenly became a little interested, and after thinking about it carefully, he couldn't apply for any big projects, at least for the time being, because he was just a mathematician.

After the Mason Mathematics Lab is established, he can apply for some computer-related projects.

But he didn't have much interest in similar projects, because most of the computer research is applied research, which involves some algorithms, architectures, etc., even if you can find the right direction, the research is very time-consuming.

Relatively speaking, in materials science and physics research, the correct research direction is more important than anything else.

If you find the right direction every time, you will get results in no time.

Of course, interest is also important.

Wang Hao hopes to complete the 'alternating gravity' experiment to gain a deeper understanding of annihilation.

However, his idea is to construct the mathematical basis of the 'annihilation theory', rather than to use this discovery to do anything or verify anything.

Annihilation is only a theory, and only he knows that it is the correct theory, even if there are more discoveries, it will not be 100% certain for the time being.

Micro theories are hard to say.

When Wang Hao was thinking about the 'alternating gravity' experiment, the gate of Xihai University was very lively.

The school welcomed a team from the Shencheng Aircraft Design and Research Institute of the Aviation Group, the famous aircraft designer Li Jianhua.

Li Jianhua's team stayed in the 103 Institute for nearly a week, and verified three sets of approximate data with the 103 Institute, and found that the corresponding wind pressure test evaluation values were all below 20.

This shocked everyone.

After that, Li Jianhua led a team to visit other relevant scientific research institutions, and later thought about it and couldn't help but come to Xihai University.

Computational studies of aerodynamics are so important for aircraft design.

If the desired results can be achieved in every calculation, the performance of the designed aircraft will definitely go up a notch.

This is much more important than visiting some research institutes.

So Li Jianhua came.

Of course, he can't say that he came to find Wang Hao, but in the name of visiting Xihai University.

What to examine?

The first thing that came to mind at Seohai University was the Navitas Laboratory, because the Navitas Laboratory was striving for the materials project of the Institute of Aeronautical Materials, a subsidiary of the Aviation Group.

Seohai University also has a power laboratory, but it has little impact at all, and it is certainly impossible to attract an aircraft design team to a small laboratory built by the university.

It is precisely because of this judgment that Xia Guobin is mainly responsible for entertaining Li Jianhua and his party.

Xia Guobin greeted Li Jianhua and his entourage, and after a warm introduction, he welcomed them into the school gate.

He took people to the Navitas Materials Lab, intending to introduce the lab's projects and R&D level.

Xia Guobin is very much looking forward to this.

But when he arrived at the door of the laboratory, he found that he couldn't find Li Jianhua.

He asked the others suspiciously, "What about your President Li's design?" Where did it go? ”

An assistant-like figure next to him said, "Mr. Li said that he went to find someone and let us go in for a visit." ”

“——？”

Xia Guobin was stunned when he heard this, and even opened his mouth in surprise, a team came to visit and investigate, and the core of the team left to find someone and let the rest of the people visit.

Why does this routine sound familiar?

Xia Guobin suddenly felt weird, and he also thought of the reason depressedly.

He already had an experience.

The last time people from the Institute of Aeronautical Materials came to visit the Navitas laboratory almost symbolically, and when they had lunch at noon, a few leaders could not be found, and later they learned that they were going to find Wang Hao, and even stayed for Wang Hao until the next day.

It seems to be the same now!

……

Xia Guobin guessed correctly.

Of course, Li Jianhua came for Wang Hao, he not only went to find Wang Hao by himself, but also brought two aerodynamics experts.

Their luck was better than that of the people in the Materials Academy, and they did not encounter a situation where they were not allowed to enter the building.

They found Wang Hao very smoothly, and then explained their intentions.

"Professor Wang, Cui Xunnian, remember? The equations he gave you, your analysis is so accurate! Li Jianhua's words let Wang Hao know the other party's intention.

He was a little curious, "Does it help you?" ”

"It's not us, it's ...... 103 institutes. The last few words were whispered in Wang Hao's ear.

Wang Hao hurriedly shook his head, "You don't need to tell me this." "He didn't want to hear anything confidential, and even if he did, he was just helping to solve the equations.

Li Jianhua nodded and said bluntly, "We are here this time to learn from you about the calculation method, is it convenient for you to say this?" He asked first.

Because I don't know what method Wang Hao used to obtain the approximate degrouping, but there is no doubt that this method is very important.

Wang Hao didn't care, "Is it useful to you?" That's just a small step forward in my research on the NS equation, if you're useful, I'll tell you about it? ”

It's not that he doesn't care at all, it's just that because similar methods have a wide range of applications and are very important in some fields, it doesn't seem good to publish papers directly.

However, holding back and being the only one who knows it has no practical meaning.

If he can help with the design of the fighter, he is still willing to do his part.

"That's great!" The aerodynamics expert next to him, Zhao Xin, immediately said excitedly.

Li Jianhua said, "I can't let you talk in vain, I will report to my superiors, whether it is a bonus, a medal, or my project, I must have a credit for you." ”

Wang Hao likes to listen to this.

He laughed, "It's just a small study, you don't have to worry too much." ”

After a few people said yes, Wang Hao took them to the Mason Mathematics Science Laboratory and went directly into the director's office.

The director's office is relatively large, the sound insulation effect is also relatively good, and the door is hung with a 'Do Not Disturb' sign, and generally no one will come to knock on the door.

When he arrived in the office, Wang Hao began to explain, "My research is based on finding the approximation of the NS equation. ”

"Have you read my research published in New Advances in Mathematics?"

Zhao Xin immediately raised his hand, "I've seen it, and I've studied it carefully." ”

"That's good."

Wang Hao said, "That's the most basic method, and it's easy to do it with a foundation." ”

"In fact, the focus is on the substitution equation, mainly the comparative analysis of the substitution equation and the original equation, in which some discrete mathematics and functional analysis methods are applied, and some Li Qun comparison methods are applied."

"I'll give you a simple example, like ......"

He wrote a determinant on the whiteboard.

Then the quick conversion writes a determinant.

"These two are the original equation and the substitution equation, so let's analyze, start the comparison from the previous bits, establish a group, and do the comparison and screening of numbers......"

"We need to ......"

"In this way, you can know the ...... through analysis"

"Wow-wow-wow-la-......"

Wang Hao spoke for more than 20 minutes in a row, which also made the faces of the three people present turn blue when they heard it.

Li Jianhua didn't understand it from the beginning, and he also had research on aerodynamics, but after all, he didn't specialize in this work.

The other two aerodynamics experts were able to keep up at first, but after a few minutes they couldn't, because some of the transformations they couldn't understand at all, and they must have involved very advanced mathematical theories.

They couldn't help but complain in their hearts, "This is called small research? ”

"It's simple?"

"Excuse me, what do you mean by difficulty? With this method, you can't learn it in a few months......"

Looking at Wang Hao, who was explaining, with a look of indifference, it seemed that he really felt that it was just a small study, and it was very easy to understand, and they all felt a kind of sadness called 'IQ limitation'.

Then they heard Wang Hao say, "This is the first conversion method, that's it, there are three more methods behind, let's analyze the method just now......"

When he found that Wang Hao wanted to continue explaining, Li Jianhua hurriedly interrupted, "Professor Wang, Professor Wang, it's enough to get here." ”

"Huh? Do you all understand? ”

"Uh~~"

"Is there something you don't understand?"

"Uh~~"

"Is this here? Here, or here? Wang Hao clicked three positions in a row.

"Uh~~"

Li Jianhua thought for a while and said, "It's from the position where you said you want to compare the original equation with the replacement equation." ”

“…… Isn't that just the beginning? ”
