Fan Qingxue is a research expert in the field of superconductivity.
He has worked as a researcher in the Superconductivity Laboratory and has more than ten years of experience in research on superconducting mechanisms.
Although I have not led a team to do large projects, I have participated in theoretical research projects and have rich relevant experience.
As long as scholars are familiar with Fan Qingxue, they all recognize his level in the field of superconductivity research.
Because of this, Wu Hui asked Fan Qingxue to come to Xihai University because he wanted Fan Qingxue to provide some professional guidance for research in the physics laboratory.
In Wu Hui's opinion, Fan Qingxue is definitely better than He Yi.
He Yi is a physics professor at Xihai University and the head of the physics laboratory, but he does not have any experience in participating in large projects, so his resume is naturally inferior to Fan Qingxue.
As for comparing it with Wang Hao, it's hard to judge.
However, Wang Hao is a mathematician and is not specialized in superconducting physics research, so he may not understand many things.
Fan Qingxue really didn't understand why the physics laboratory held a theoretical meeting.
Based on his experience, some research projects that have no clue will focus on theoretical demonstration, such as the replica experiment of communicating gravity, which is the kind of research that has no clue.
Because there is very little relevant information and some references are not of great significance, it is natural to conduct certain theoretical demonstrations.
What we are doing now is also an experiment on AC gravity, but we have been able to create an AC gravity field. We are only studying the influencing factors of the AC gravity field, which is equivalent to a purely comparative research project.
Comparing research projects, what can be demonstrated?
This kind of research is to conduct experiments directly and adjust different parameters to analyze the results. Even if you make an argument, it is impossible to directly deduce the results, so it is naturally meaningless.
For example, in the simplest way, study the relationship between current and resistance.
Directly conduct experiments to adjust the voltage, and then detect the intensity of the current, and you can get the value of the resistance.
Current research is the same.
As long as the parameters are continuously adjusted and analyzed based on the results obtained, some interfering factors can be identified and eliminated, and relevant conclusions can be drawn.
Fan Qingxue thought so, but he obviously couldn't convince Wang Hao, because Wang Hao's goal was to surpass the two competitors.
With normal research methods, it is simply impossible to surpass the other two large superconducting institutions.
Definitely.
In this case, other methods must be used.
Fan Qingxue could only sit aside and watch.
…
The theoretical meeting officially begins.
He Yi first gave a theoretical explanation, and then explained some possible influencing factors.
Everyone records it.
The meeting process is to allow everyone to explain their thoughts on each factor.
Everyone is very positive because they already have "relevant experience" and know that theoretical demonstration is very important.
Even if it is just a comparative experiment, as Wang Hao said, if you want to surpass the other two large laboratories, you must conduct more precise theoretical demonstrations, so that you can reduce the number of experiments and obtain more accurate data and results.
The study of AC gravity field may be related to many factors.…
He Yi mentioned an important factor at the beginning, "Factors related to superconducting materials are very critical."
Superconducting materials are not just one factor. The first is the arrangement and layout of superconducting materials, that is, how to place superconductors and how to arrange them.
This is also an important factor supporting the creation of communicative gravity.
The arrangement of superconducting materials is not just a flat or simple spiral structure, but their demonstration did not conduct a detailed analysis, but only made certain modifications to the original structure.
The argument was not very in-depth.
Wang Hao decided to continue the original "four-node layout" for the first experiment, which means placing the superconducting material in four fixed positions, greatly increasing the width of the material. It can be understood as an arrangement of two wires and small spheres at intervals.
This factor does not change.
Changes in the layout of superconducting materials are to make the superconducting materials 'thicker' or change the arrangement to see if it can affect the final result.
The impact of superconducting materials also lies in the difference in materials.
Many superconducting materials have now been discovered, which can be divided into low-temperature superconducting materials and high-temperature superconducting materials based on the requirements for achieving superconducting state characteristics. Different superconducting materials may also have different effects on the AC gravity field.
Superconducting materials can also be divided by the composition of the material, including oxides, metal alloys, organic materials and even liquid materials, etc.
The second factor is related to electricity. Voltage and transmission power may have a direct impact. Because superconducting materials theoretically have no resistance, the current will be amplified many times, and even theoretically the current is infinite.
Of course, the actual current cannot be infinite.
"Critical current density may also be one of the influencing factors of the AC gravity field." Wang Hao emphasized.
The critical current density is related to the critical magnetic field.
This is a complex issue.
The first theoretical meeting does not need to be too in-depth, just analyze the superficial factors together.
In addition to the effects of superconducting materials and electricity, there are other factors that may also affect the AC gravity field.
There are many factors, including ambient temperature, the influence of altitude, air density, air flow, and even the spin of the earth, etc.
Of course, the influence of electromagnetic field forces cannot be directly ruled out.
The current research is to eliminate factors that have no influence and find out those factors that have a direct influence.
Each item was discussed at the meeting.
Everyone spoke enthusiastically and expressed their opinions.
Wang Hao conducted targeted analysis, while He Yi was mainly responsible for controlling the meeting process and making a series of records.
Everyone has a clear division of labor.
The meeting lasted for more than three hours and did not end until one o'clock in the afternoon.
Fan Qingxue had been sitting nearby and listening, watching the meeting being summarized one by one, but he always felt a little weird because some factors were directly excluded by the 'theory'.
For example, air flow factors.
Everyone discussed it in detail, and finally concluded that the flow of air cannot affect the AC gravity field.…
But, doesn’t this need to be confirmed by experiments?
After the meeting ended, Wang Hao did not forget about the expert group and invited them to have a meal together. Fan Qingxue also asked on the way, "Professor Wang, you just eliminated some factors in this meeting. Isn't it a bit unscientific?"
Wang Hao nodded and said, "In fact, in my opinion, experiments should be done to prove each factor, rather than being eliminated through analysis."
"Then why...?" Fan Qingxue didn't understand.
Wang Hao explained in one sentence, "It's very simple. Because we have two very strong opponents, we can't waste time on factors that may have no impact."
"We have to complete research more efficiently."
"Our funds are also limited. We only have allocations from schools now. Funds from the province will have to wait for a few days, not to mention the foundation." He shook his head helplessly.
Fan Qingxue had nothing to say after hearing this.
Although the process is indeed a bit unscientific, after listening to Wang Hao's explanation, it feels like it is true. Because of limited funds and two strong opponents, it is impossible to design experiments to study every factor.
…
The morning meeting was a theoretical demonstration. They identified some 'possible' influencing factors and eliminated some 'unlikely' related factors.
Experiments are designed based on theoretical analysis results.
The most difficult part is the layout of the superconducting material, because it still takes a while to prepare for changes to the overall device.
The laboratory is busy in the afternoon. I hope I can complete the preparations in the afternoon and conduct the experiment tomorrow morning.
The expert group left in the afternoon. They were really just here for a formality.
Fan Qingxue did not leave.
One reason is because he came with a work assignment, which was to provide research guidance to the physics laboratory.
This is the work assigned by Wu Hui.
On the other hand, it was because he was curious about the results of the theoretical argument.
Fan Qingxue felt that there were many imprecisions in it, and it seemed that he had come to some inexplicable conclusions. At the same time, he also wanted to see if the experimental results were what he thought, and they were meaningless.
This is his judgment, a judgment based on personal experience.
The theoretical demonstration meeting was very lively and lasted for more than three hours, but it is difficult to say whether it had any specific effects.
Fan Qingxue still does not believe that theoretical demonstration can have an effect on experiments.
At eight o'clock the next morning, the physics laboratory was already busy.
They are making final preparations for the experiment.
When the experiment was about to begin, Fan Qingxue stood with Wang Hao. He thought for a long time last night and decided to talk to Wang Hao again, "Professor Wang, I think the focus of this experimental research is on the layout of superconducting materials.
Your four-node design is very critical."
"I listened to your meeting yesterday, but there seemed to be no relevant evidence. Why is that?"
In Fan Qingxue's view, the layout of superconducting materials is the most important, because it involves very complex designs.
It is precisely because of this design that the AC gravity experiment was successfully reproduced.…
This is also the only difficulty in the research.
Many people who know the relevant research believe that it is difficult to improve the four-node design through ordinary comparative experiments.
When Wang Hao heard what Fan Qingxue said, he nodded and said, "This is confidential."
"??"
Fan Qingxue was stunned for a long time.
Wang Hao said seriously, "Professor Fan, let me put it bluntly. The key to the AC gravity experiment lies in the design of the four nodes and the layout of the superconducting material."
"So there is no doubt that the layout of the superconducting material is directly related to the strength of the AC gravity field."
"This correlation is likely to become a general direction of research. It is difficult to achieve results in this direction with the comparative experimental research we are doing now."
"However, we will continue to explore in this direction. However, we cannot let too many people know about the design changes in the experiment."
"This is confidential."
"Usually only a few core people discuss it, and I won't talk about it in meetings."
Fan Qingxue suddenly understood, but he still felt a little awkward because he himself was excluded. He asked with depression, "In this experiment, there should be no changes to the structural layout of the superconducting material, right?"
He was asking whether the changes in the experiment were as summarized yesterday, rather than adding some so-called 'confidential' content.
Wang Hao smiled and said, "That still requires follow-up research. Now we are only conducting experiments on simple influencing factors."
As the two of them talked, the experiment was ready.
Wang Hao, Fan Qingxue, He Yi, and Xiao Xinyu checked the equipment together. After confirming that there were no problems, they walked away and stood farther away and prepared to conduct experiments.
"let's start!"
After everyone was ready, Wang Hao started the experiment directly.
Equipment, officially started!
Along with the buzzing of the machine, the people surrounding the experimental equipment also began to get busy. They continued to fill the delivery pipes with liquid nitrogen and other cooling materials, and specialized people kept an eye on the voltage and power values.
Everyone else looked at the parameters of the detection equipment and the changes in the balloon above.
"It's floating!"
Fan Qingxue did not participate in the AC Gravity Reproduction Experiment at the Capital University Basic Science Center. This was the first time he saw the AC Gravity Experiment, and he was a little shocked when he discovered that the balloon suddenly floated.
He has only read some information on this.
Others in the lab have seen it once and are more concerned with the detection parameters.
Someone soon reported the value, "Roughly estimated, our gravity has been reduced by about 2%!"
"Keep experimenting!"
"Cool down again!"
"Increase the transmission power!"
After Wang Hao heard the numerical values, he issued several orders in succession, and others also got busy.
Soon another data was calculated, "gravity has been reduced by more than 2.3%."
"continue!"
Fan Qingxue was dumbfounded as he looked at the data shouted out one by one. This was his first time to see the AC gravity experiment live, but he had seen relevant information.
The exchange gravity experiment conducted by the Capital University Basic Science Center found that the final gravity reduction value was between 1.7% and 1.8%.…
This value is already higher than the physics laboratory report.
Now it has increased to more than 2.3%, and the increase can be described as amazing.
Fan Qingxue did not expect this result. He originally thought that even if there was an improvement, it would only be 0.1% at most, and it would be very good to reach the level of Capital University's replica experiment at that time.
It is difficult to explain the problem with this level of improvement, and it is necessary to conduct several consecutive experiments to determine the influencing parameters.
The other two major superconducting institutions have done this.
The first experiment in the physics laboratory was to increase the value by more than 0.5%. Such a huge improvement, even through just one experiment, some influencing factors can be determined.
Such an experiment is worth several experiments.
Fan Qingxue felt that it was very unscientific. Is there such a big improvement in the first experiment?
In addition, he didn't understand the theoretical meeting. He just felt that some conclusions were drawn in a hurry, as if they were just to analyze the maximum possibility instead of rigorously using experiments to rule out the problems.
Fan Qingxue also felt that the people in the physics laboratory had an amazing "admiration" for Wang Hao, which could even be described as "fanatic". As long as it was what Wang Hao said, no one would question it.
The theoretical conference is Wang Hao’s forum.
With so many problems existing, when we actually entered the experiment, the effect turned out to be so good, with an increase of more than 0.5% at once?
Fan Qingxue stood aside and watched, completely at a loss what to say.
He found that his feelings were very similar to the first time he participated in the superconducting experiment. He had no idea what to do or why he came to the conclusion. He just had someone to do the experiment with him.
What happened before him was beyond the scope of his knowledge and experience.
finally.
The intensity of the AC gravity field has been increased to 2.5%-2.6%, which is about 0.9% higher than the experiment done by the Capital University Basic Science Center.
This major development makes everyone in the laboratory very excited.
After the experiment was over, they actively carried out the finishing work and recorded all the data in detail.
After a busy morning, Wang Hao organized an experiment summary meeting in the afternoon.
Fan Qingxue didn't say a word the whole time.
He felt that he had nothing to say. He originally came here to provide guidance in the physics laboratory, but he found that he was of no use. He didn't even understand how to conduct a theoretical argument, let alone why, such an argument had such an effect. It can be so good.
"People do a comparative communication experiment and demonstrate that the efficiency can be greatly improved, but I even think that the argument is useless?"
"Is my idea too backward?"
"The experimental results prove that they are scientific and I am unscientific..."
When Fan Qingxue was thinking lonely, Wang Hao finished summarizing the experimental data. He glanced at the audience and noticed Fan Qingxue.
He felt that Fan Qingxue should be taken seriously.
After all, the other party is a superconducting expert, and was specially sent by Academician Wu Hui to help.
Wang Hao made a gesture of invitation and said, "Professor Fan, you are a professional superconductor expert. Come and talk to us and give us some advice."
Everyone looked at it expectantly.
Fan Qingxue was stunned for a long time with his mouth half open, and finally said, "The work done in your laboratory is perfect."
"I feel like there's nothing left to say."
That night, Fan Qingxue took a flight back to the capital, and returned to his job the next day.
Wu Hui was surprised that Fan Qingxue came back so quickly. He came over and asked, "Didn't I ask you to guide the physics laboratory? Why are you back so soon? How is the progress there?"
"..."
Fan Qingxue held the information in his hand and raised his head without speaking for a long time.
Finally, he sighed and said, "Professor Wu, I went to Xihai University. I feel that my level is still too far behind."
"So when I came back, I wanted to read more information, increase my knowledge, and learn a little bit."
"As for guidance..."
Fan Qingxue paused for a moment and said with a wry smile, "With my level, I am not qualified to guide them. I was mentored..."
