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.
