Chapter 161 The aircraft chief designer comes to visit, Wang Hao: It’s just a simple matter
Academy of Sciences.
Superconducting Physics Laboratory, Nuclear Magnetic Resonance Research Office.
Several academicians and researchers are sitting in the office talking about the latest experiments. They are doing a theoretical research project on superconductivity, which uses nuclear magnetic resonance to study the principles and mechanisms of superconductivity.
This research is a basic theoretical study of superconductivity.
Because the latest experiment failed to meet expectations, several people were not in a good mood when talking about it, but in fact, it was expected that there were no expectations.
Research on theoretical mechanisms is inherently difficult. The project has lasted for ten years and there has been no progress for a long time.
Fortunately, the country attaches great importance to cutting-edge superconducting research, and project funds are continuously supplied.
Academician Zhang Zhongxian is 60 years old. He is the main leader of the project and a well-known superconducting expert in China. He encouraged, "This experiment did not meet expectations, but it can be regarded as laying the foundation for the next experiment.
Don’t take it too seriously.”
Zhou Pengcheng, the researcher next to him, shook his head and sighed, "We have had no results for a long time. I feel that the theoretical research on superconductivity has reached a bottleneck."
The others were silent after hearing this.
This is the truth.
Superconductivity refers to the state in which the resistance of a conductor is zero at a certain temperature.
The phenomenon of superconductivity has been discovered for hundreds of years, and superconducting technology has been around for decades. It has always been considered a cutting-edge technology, but due to limitations in usage conditions, it has not yet been able to be applied on a large scale.
Now the superconducting industry is studying how to break through technical bottlenecks, and theoretical support is very important.
Many people in the industry believe that without a higher-level breakthrough in theory, it will be very difficult to apply technology on a large scale.
Theoretical research limits the development of technology.
Because of this, various countries are constantly investing in research on the theoretical mechanism of superconductivity.
Another researcher, Xiang Qiansheng from the Institute of Electrical Engineering of the Academy of Sciences, said, "Because of this, we support research in various directions related to superconductivity. Last year, even the small laboratory of Xihai University applied for theoretical research
Project, what does it say about studying superconducting antigravity phenomena?”
He shook his head as he spoke, obviously not optimistic about it.
The theory of 'communicating gravity' appeared thirty years ago, and the actual experimental discovery was reported twenty years ago.
As the most powerful superconducting laboratory of the Academy of Sciences in China, they have naturally done relevant research, but later found that they could not replicate the experiment.
They spent 20 million on this project, but found nothing.
Later, I had no choice but to give up.
They are a national key laboratory affiliated to the Academy of Sciences. They have academicians and researchers from the Academy of Sciences. Each one of them can be said to be an expert in superconductivity. They spent 20 million yuan and found nothing.
The Physics Laboratory of Xihai University is applying for a grant of two to three million yuan. What results do you expect?
How can it be!
Zhou Pengcheng also followed, "This kind of project is obviously just a gimmick to apply for some funds. Everyone knows that there is no possibility of discovery."
Zhang Zhongxian said, "This also shows that the country attaches great importance to this aspect. Superconducting research is so critical. This may become a key technology for future competition, and theoretical research is even more top priority."
Several people started shaking their heads and sighing again.
No matter what other small laboratories are like, their research has indeed reached a bottleneck, and it is very difficult to think of a breakthrough in a certain direction.
This bottleneck even makes them don't know how to design experiments and continue research.
Of course, it is normal for the research on the theoretical mechanism of superconductivity to fall into a bottleneck and achieve no results. It requires continuous summary and research to find the right direction.
…
Sokai University, Physics Laboratory.
Wang Hao said he wanted to participate in the experiment, so naturally he actually participated.
He arrived at the physics laboratory the next day, prepared new experiments with others, and gained a detailed understanding of all aspects of the experiment.
Then he found that the experimental design was very crude.
This is mainly because there is very little known data content, and they can only try to replicate the experiment based on the data content.
It is difficult to say whether the information is true or false.
Wang Hao knew even less about the experiment. He only watched to understand some of the contents and did not participate in the preparation of the experiment.
In addition, experimental preparations cannot be completed at once, because some materials require special approval, and some require a certain amount of time to purchase.
"It will take at least a week." He Yi estimated the time, "The last experiment consumed too much material, and we need to purchase new materials."
Wang Hao asked, "Is there any difference between this experiment and the last one?"
"this……"
He Yi hesitated and thought for a moment, "I discussed it with Professor Xiao and felt that a new conductor layout method should be adopted."
"Is it just the conductor layout..." Wang Hao sounded a little unreliable.
He Yi also knew that it was somewhat 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 case, don't rush to prepare materials first. Funds are limited. Let's study it as a whole first and think about the specific experiments before making preparations."
"That's fine." He Yi nodded.
This experiment already has experience from the last one, so it doesn’t take that long to prepare. But because the last time failed, it’s hard to say whether the experience will be useful.
He Yi, Xiao Xinyu and Wang Hao discussed it and decided to summarize the last experiment again.
Just prepare the new experiment slowly. With the summary of the last experiment, you can study the method of the new experiment and prepare for the experiment after everything is thought out.
The physics laboratory held an internal summary meeting.
The meeting is mainly to summarize the last experiment, that is, to analyze why the experiment failed.
Of course, there are many possible reasons.
Wang Hao also participated in the meeting. He thought he would just listen in, but he soon found that the meeting was very awkward. There were almost no other people talking, only He Yi and Xiao Xinyu were talking.
Communication gravity is a phenomenon that may or may not exist. There are only a few reports in the world, and very little information can be found.
Although they have conducted relevant research, the progress of the research has been very little. At most, they can support the writing of a few papers, but they are only experimental papers. Because they have not been able to successfully reproduce the experiment, there is even less content that can be summarized.
Yan Jing was trusted by He Yi, but she only talked about some experimental data and was unable to enter the theoretical content from the experimental data.
He Yi finally 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 an amateur in physics research, and I am even more of an outsider in superconductivity research."
He continued, "However, I have read a lot of relevant information recently, and I have a little personal understanding of this research."
"I think this kind of research, if you don't have a good idea, just analyze it from the theoretical mechanism?" 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. Judging from this sentence, Wang Hao was indeed an outsider.
Physics research first discovers phenomena and then analyzes the principles.
Because of this, they are obsessed with replicating the experiment. Only by replicating the experiment can they analyze the data and find out the underlying mechanism.
Now Wang Hao said to analyze the principle first, how can it be possible to analyze it?
He Yi just looked at Wang Hao without showing his attitude.
Wang Hao continued, "In terms of theoretical mechanism, we must first study the theoretical mechanism of superconductivity."
"There was a theory called degenerate phase superconductivity more than ten years ago. You should all know this."
"According to this theory, the microphysical mechanism of superconductivity has been discovered, which is the relative separation of the 'superconducting free electron gas' and the 'degenerate positive ion lattice' in the superconducting state, without any collision between the two.
."
"Based on this principle to relate the possibility of antigravity, I think it is related to the ion lattice formed in the superconducting state?"
This is based on a personal judgment about research, but the system directly feeds back the results.
Because of this, Wang Hao will discuss it from a theoretical perspective.
"We assume it is directly related to the ion lattice." After receiving feedback from the system, Wang Hao suddenly became confident, "So how can we produce the 'exchange gravity' phenomenon?"
"Is there a possibility that it is due to the spin of the ion lattice in a certain 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 barrier to gravity, or a special case of mixing magnetic and electric fields? These are all possible."
"We analyze it in turn to get a certain hypothesis to verify. This is the method of microphysical research."
The last sentence made everyone nod.
In the study of the mechanism of superconductivity, new physical phenomena are almost always discovered, and then the mechanism is deduced based on the phenomena.
However, the study of microphysics starts from theory, because there are many microphysical phenomena that cannot be directly explained, so theoretical physics is needed to provide support, and after theoretical physics is framed, other problems can be deduced.
Things like the Higgs particle and neutrinos were discovered in experiments only after existing theories.
Wang Hao initially said that he should study the theoretical mechanism first, which everyone present must have disagreed with. However, if you just assume a theory and then design experiments based on theoretical derivation, it makes sense to a certain extent.
Wang Hao's speech consisted of asking some questions and then conducting a detailed analysis of each part.
It took more than an hour to talk like this.
The meeting suddenly became lively.
Because I was just making assumptions and imaginings, many people began to speak enthusiastically and boldly expressed their thoughts. The "teaching" speech quickly turned into "scientific research". The difference is that one person speaks and many people speak together.
Research.
Wang Hao found that he also had more inspiration.
This inspiration is not reflected in the mission, because it is not directly related to the research of annihilation force, but is only reflected in his thoughts and judgments.
The meeting lasted for more than two hours.
Wang Hao concluded, "So a more likely conclusion is that the emergence of the 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. We can design experiments based on this inference."
"I think next, you will 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, Wang Hao was just asked to share his thoughts, but he turned the meeting into a 'theoretical discussion', and then everyone spoke enthusiastically, and a 'possible theory' was actually developed.
this……
Even though I personally participated in it, it still feels a little weird no matter how you think about it.
Why didn't this happen in the meetings he chaired?
its not right!
"I was originally presiding over this meeting." He Yi tugged at the corner of his mouth. He realized that Wang Hao should be the one to 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.
His gains were also very great. Just the knowledge and ideas in his mind, as well as a deeper understanding of superconductivity, made him feel that he had benefited a lot.
In addition, he found that he was very good at leading scientific research projects.
Because of the "Gift of Teaching" and "The Gift of Scientific Research", he can easily lead the discussion to the right track, which is very helpful for analyzing experiments or analyzing theoretical mechanisms.
Then naturally the efficiency of project research will be very high.
"Should I also apply for a big project?" Wang Hao suddenly became interested. After thinking about it carefully, he decided to forget it. At least for the time being, he couldn't apply for any big project because he was just a math scholar.
After the Mason Mathematical Sciences Laboratory is established, he can apply for some computer-related projects.
However, he is not very interested in similar projects, because most computer research is applied research, involving at most some algorithms, architectures, etc. Even if he can find the right direction, 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 can find the right direction every time, you will get results quickly.
Of course, interest is also very important.
Wang Hao hopes to complete the 'exchange gravity' experiment to gain a deeper understanding of the annihilation force.
However, his idea was to construct the mathematical basis of the 'annihilation force theory', rather than to use this discovery to do or verify anything.
The annihilation force is just a theory, and only he knows that it is a correct theory. Even if there are more discoveries, it cannot be 100% certain for the time being.
Microscopic theory is difficult to say.
When Wang Hao was thinking about the 'exchange gravity' experiment, the gate of Xihai University was very busy.
The school welcomed a team from the Shencheng Aircraft Design Institute of the Aviation Group and the famous aircraft designer Li Jianhua.
Li Jianhua's team stayed at Institute 103 for nearly a week and verified three sets of approximate data with Institute 103. It was found that the corresponding wind pressure test and evaluation values were all below 20.
This shocked everyone.
After that, Li Jianhua led the team to visit other related scientific research institutions, and then he couldn't help but come to Xihai University after thinking about this matter.
Computational research on aerodynamics is extremely important to aircraft design.
If ideal results can be achieved in every calculation, the performance of the designed aircraft will definitely rise to a higher level.
This is much more important than visiting some research institutions.
So here comes Li Jianhua.
Of course, he couldn't say that he came to see Wang Hao, but came in the name of visiting Xihai University.
What to investigate?
The first thing Xihai University thought of was naturally the NanoLab, because the NanoLab is competing for the materials project of the Aeronautical Materials Institute under the Aviation Group.
Xihai University also has a power laboratory, but it has little impact. It is a small laboratory built by the school and it is certainly impossible to attract an aircraft design team.
Because of this judgment, Xia Guobin was mainly responsible for entertaining Li Jianhua and his party.
Xia Guobin came over to welcome Li Jianhua and his party. After introducing them warmly, he welcomed them into the school gate.
He took people to the Nanomaterials Laboratory, intending to introduce the laboratory's projects and research and development levels.
Xia Guobin is looking forward to this very much.
But when he arrived at the entrance of the laboratory, he found that Li Jianhua was nowhere to be found.
He asked the others in confusion, "Where is your design, Mr. Li? Where have you gone?"
An assistant-like figure next to him said, "General Manager Li said he was looking for someone and asked us to go in and visit."
"——?"
Xia Guobin was stunned when he heard this, and even opened his mouth in surprise. A team came to visit and inspect, but the core member of the team left to find someone, leaving the rest of the people to visit.
Why does this routine sound familiar?
Xia Guobin suddenly felt strange, and he thought about the reason depressedly.
He has already had an experience.
The last time people from the Aeronautical Materials Institute visited the NanoVis Laboratory almost symbolically, when it was time to eat at noon, the leaders could not be found. Later I found out that they were looking for Wang Hao, even for Wang Hao.
Hao stayed until the next day.
It seems to be the same now!
…
Xia Guobin guessed correctly.
Of course Li Jianhua came here for Wang Hao. He not only went to Wang Hao himself, but also brought two aerodynamics experts with him.
Their luck is better than that of the people in the Materials Institute, and they have not encountered any problems in not being allowed to enter the building.
They found Wang Hao smoothly and explained their purpose of coming.
"Professor Wang, Cui Xunnian, do you still remember? Those equations he gave you, your analysis was so accurate!" Li Jianhua's words let Wang Hao know the purpose of the other party's visit.
He was a little curious, "Will it be helpful to you?"
"It's not us, it's... Institute 103." The last few words were whispered in Wang Hao's ear.
Wang Hao quickly shook his head, "You don't need to tell me these things." He didn't want to hear any confidential information. Even if he participated, he just helped solve the equation.
Li Jianhua nodded and said bluntly, "We are here this time to learn about the calculation method. Is it convenient for you to tell me?" He asked first.
Because I don’t know what method Wang Hao used to obtain the approximate solution, 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 progress in my study of NS equations. If it's useful to you, I'll tell you about it?"
It’s not that he doesn’t care at all, it’s just that similar methods have broad application prospects and are very important in certain fields. It doesn’t seem good to publish papers directly.
However, there is no practical significance in holding it in until only you know it.
If it can help in fighter design, he is still willing to do his part.
"That's great!" Zhao Xin, an aerodynamics expert next to him, immediately said excitedly.
Li Jianhua said, "I can't let you talk in vain. I will report it to my superiors. Whether it is bonuses, medals, or my projects, you will definitely have a share of the credit."
Wang Hao liked to hear this.
He smiled and said, "It's just a small study, you don't need to pay too much attention to it."
After several people agreed, Wang Hao took them to the Mason Mathematical Science Laboratory and directly into the director's office.
The director's office is relatively large and has better sound insulation. There is a "Do Not Disturb" sign on the door, so no one usually comes and knocks on the door.
When he arrived in the office, Wang Hao began to explain, "My research is based on obtaining the approximate value of the NS equation."
"Have you read the research I published in New Advances in Mathematics?"
Zhao Xin immediately raised his hand, "I have read it and studied it carefully."
"That's good."
Wang Hao said, "That is the most basic method. Once you have the foundation, it will be easier to handle."
"In fact, the focus is on the replacement equation, mainly the comparative analysis of the replacement equation and the original equation, in which some discrete mathematics and functional analysis methods are applied, as well as some comparative methods of Lie groups."
"Let me give you a simple example, for example..."
He wrote a determinant on the whiteboard.
Then quickly converted and wrote another determinant.
"These two are the original equation and the replacement equation, so let's analyze it, start the comparison from the front, establish a group, and do numerical comparison and screening..."
"We need to..."
"After this round, we can know through analysis..."
"Wow wow wow..."
Wang Hao kept talking for more than twenty minutes, which made the three people present turn blue.
Li Jianhua couldn't understand it from the beginning. He also did research on aerodynamics, but after all, he was not specialized in this work.
The other two aerodynamics experts could keep up at first, but after a few minutes they couldn't because they couldn't understand some of the transformations, which must have involved very advanced mathematical theories.
They couldn't help but complain, "Is this called small research?"
"Is this called very simple?"
"Excuse me, what does it mean to be difficult? You can't learn this method even if you study it for several months..."
Looking at Wang Hao who was explaining, he had a nonchalant look on his face. It seemed that he really felt that it was just a small study and it was very easy to understand. They all felt a kind of sadness called "limited IQ".
Next they heard Wang Hao say, "This is the first conversion method, that's it. There are three more methods later. Let's analyze the method just now..."
When he realized that Wang Hao was about to continue explaining, Li Jianhua quickly interrupted, "Professor Wang, Professor Wang, that's enough here, that's enough."
"Ah? Do you all understand?"
"Uh~~"
"Is there something you don't understand?"
"Uh~~"
"Is it here? Here, or here?" Wang Hao clicked on three locations in succession.
"Uh~~"
Li Jianhua thought for a while and said, "That's where you said you want to compare the original equation and the replacement equation."
