From University Lecturer to Chief Academician

Fan Qingxue is a research expert in the field of superconductivity.

He worked as a researcher in the superconducting laboratory and has more than ten years of experience in superconducting mechanism research.

Although I have not led a team to do large-scale projects, but because I have participated in theoretical research projects, I have rich relevant experience.

Scholars who are familiar with Fan Qingxue will recognize his level in the field of superconductivity research.

Because of this, Wu Hui asked Fan Qingxue to come to Xihai University, just to let Fan Qingxue give some professional guidance to the research of the physics laboratory.

In Wu Hui's opinion, Fan Qingxue must be better than He Yi.

He Yi is a professor of physics 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 that of Fan Qingxue.

As for the comparison with Wang Hao, it is difficult to judge.

However, Wang Hao is a mathematician, not a professional superconducting physics research, so there may be a lot of things he doesn't understand.

Fan Qingxue did not understand the theoretical meeting held in the physics laboratory.

According to his experience, some research projects without a clue will focus on theoretical demonstrations, such as the replica experiment of communication gravity, which belongs to the kind of research without a clue.

Because there are very few relevant materials, and some references are of little significance, it is natural to carry out certain theoretical demonstrations.

What is being done now is also an experiment of communication gravity, but it has been able to create an communication gravity field, and the research is only on the influencing factors of the communication gravity field, which is tantamount to a purely comparative research project.

Contrasting research projects, what can be argued?

This kind of research is to directly conduct experiments and adjust different parameters to analyze the results. Even if it is an argument, it is impossible to directly derive the results, so it is naturally meaningless.

For example, the simplest is to study the relationship between current and resistance.

Directly conduct experiments to adjust the voltage, and then detect the intensity of the current, and then the value of the resistance can be obtained.

The current research is the same.

As long as the parameters are constantly adjusted, and then analyzed according to the obtained results, some interference factors can be determined and eliminated, and relevant conclusions can be obtained.

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 impossible to surpass the other two large superconducting institutions.

Definitely.

In this case, other methods must be used.

Fan Qingxue could only sit and watch.

...

The theory session officially begins.

He Yi first opened his mouth to elaborate on the theory, and then explained some possible influencing factors.

Everyone records it.

The meeting process is to let everyone explain their ideas for each factor.

Everyone is very positive because they already have 'relevant experience' and know that the theoretical argument is very important.

Even if it is just a comparison experiment, as Wang Hao said, if you want to surpass the other two large-scale laboratories, you must conduct more accurate theoretical demonstrations to reduce the number of experiments and obtain more accurate data and results.

The study of the AC gravity field may be related to many factors.

He Yi mentioned an important factor when he came up, "The factors related to superconducting materials are very critical."

The factor of superconducting materials is not just one factor. The first is the arrangement and layout of superconducting materials, that is, how to place superconductors and how to arrange superconductors.

This is also an important factor supporting the generation of AC gravity.

The arrangement of superconducting materials is not just a tile or a simple helical structure, but their argument did not carry out a detailed analysis, but only made certain modifications to the original structure.

The argument didn't go very deep either.

Wang Hao decided to continue the original "four-node layout" for the first experiment, that is, to place the superconducting material at four fixed positions and greatly increase the width of the material, which can be understood as the arrangement of two wires and small spheres at intervals.

This factor does not change.

The change in the layout of the superconducting material is to make the superconducting material 'thicker', or change the way of arrangement, to see if it can affect the final result.

The influence of superconducting materials also lies in the difference of materials.

Now many superconducting materials have been discovered, which can be divided into low-temperature superconducting materials and high-temperature superconducting materials according to the characteristics of the superconducting state. Different superconducting materials may have different effects on the AC gravity field.

Superconducting materials can also be divided by the composition of materials, including oxides, metal alloys, organic materials and even liquid materials.

The second factor is related to electricity. Voltage and transmission power may have a direct impact, because superconducting materials theoretically have no resistance, and the current will be amplified many times, even theoretically, the current is infinite.

Of course, the actual current cannot be infinite.

"The critical current density may also be one of the influencing factors of the AC gravity field." Wang Hao especially emphasized.

The critical current density is related to the critical magnetic field.

This is a complicated question.

The first theoretical meeting does not need to be too in-depth. It is enough for everyone to analyze the superficial factors together.

In addition to the effects of superconducting materials and electricity, there are other factors that may affect the AC gravitational field.

These factors are more, including the influence of ambient temperature, altitude, air density, air flow, and even the spin of the earth, etc.

Of course, the influence of electromagnetic field force cannot be ruled out directly.

The current research is to eliminate the 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 views.

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 also went on for more than three hours and didn't end until one o'clock in the noon.

Fan Qingxue has been sitting by the side and listening, watching the meeting summarize one by one, but he always feels a little weird, because some factors are directly excluded by the 'theory'.

For example, the factor of air movement.

Everyone discussed it in detail, and finally believed that the flow of air cannot affect the exchange gravity field.

But doesn't this need an experiment to prove it?

After the meeting ended, Wang Hao didn't forget about the expert group, so he invited them to dinner together. On the way, Fan Qingxue also asked, "Professor Wang, it's unscientific for you to exclude some factors directly in this meeting?"

Wang Hao nodded and said, "Actually, in my opinion, experiments should be done to prove each factor, instead of being ruled out 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 some factors that may have no effect."

"We have to do research more efficiently."

"Our funds are also limited. Right now, we only have funds from the school, and the funds from the province will have to wait for a few days, let alone the foundation." He shook his head helplessly.

Fan Qingxue had nothing to say after hearing this.

Although the process is indeed a bit unscientific, but listening to Wang Hao's explanation, I feel that it is true. Because of limited funds and two strong opponents, it is impossible to design experiments for every factor.

...

The morning meeting was a demonstration of the theory. They identified some 'possible' factors and excluded some 'unlikely' related factors.

The experiment is designed according to the theoretical analysis results.

The most difficult thing is the layout of superconducting materials, because it takes a while to prepare for changes to the overall device.

The laboratory is busy in the afternoon, and I hope that I can complete the preparations in one afternoon and wait for the experiment tomorrow morning.

The members of the expert group left in the afternoon, and they really came for a formality.

Fan Qingxue did not leave.

One is because he came with a work task, which is to conduct research guidance for the physics laboratory.

This is the job that Wu Hui explained.

On the other hand, it is because he is curious about the results of theoretical demonstrations.

Fan Qingxue felt that there were a lot of inaccuracies in it, and it seemed that he came to a conclusion inexplicably. At the same time, he also wanted to see if the experimental results were as he thought, and it was meaningless.

This is his judgment, based on personal experience.

The atmosphere of the theoretical demonstration meeting was very active, and it went on for more than three hours, but it is hard to say whether it has any effect.

Fan Qingxue still does not believe that theoretical demonstrations can have an effect on experiments.

At eight o'clock the next morning, the physics lab was already busy.

They are making final preparations for the experiment.

When the experiment was about to start, 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 study is on the layout of superconducting materials. Your four-node design is critical."

"I listened to your meeting yesterday, but there seems to be no relevant arguments. Why?"

In Fan Qingxue's view, the layout of superconducting materials is the most important, because it involves a very complicated design.

Because of this design, the AC gravity experiment was successfully reproduced.

This is also the only difficulty in the study.

Many people who know the relevant research think that it is difficult to improve the four-node design by ordinary comparative experiments.

Wang Hao nodded when he heard what Fan Qingxue said, "This is a secret."

"??"

Fan Qingxue was stunned for a long time.

Wang Hao said seriously, "Professor Fan, let me just say it bluntly. The key to the AC gravity experiment lies in the design of the four nodes, which lies in 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 alternating gravitational field."

"This correlation is likely to become the general direction of research. It is difficult to achieve results in this direction for the comparative experimental research we are doing now."

"However, we will continue to explore in this direction. However, changes in the design of the experiment should not be known to too many people."

"It's classified."

"Generally, only a few core people discuss it, and I won't say this at the meeting."

Fan Qingxue suddenly realized, but he still felt a little awkward because he himself was excluded. He asked depressedly, "This experiment should not have changed the structure and layout of the superconducting material, right?"

He was asking whether the changes in the experiment were all the same as those summarized yesterday, rather than adding some so-called 'confidential' content.

Wang Hao said with a smile, "That still needs to be a follow-up research direction. Now we are only conducting experiments on simple influencing factors."

When the two were talking, the experiment was ready.

Wang Hao, Fan Qingxue, He Yi, and Xiao Xinyu checked the condition of the equipment together. After confirming that there was no problem, they walked away and stood a little far away, and prepared to conduct experiments.

"let's start!"

After everyone was ready, Wang Hao started the experiment directly.

Equipment, officially launched!

Accompanied by the buzzing of the machine, the personnel around the experimental equipment also began to get busy. They kept filling the delivery pipes with liquid nitrogen and other cooling materials, and there were dedicated personnel staring at the voltage and power values.

Everyone else watched the parameters of the detection device and the balloon above it change.

"It's floating!"

Fan Qingxue did not participate in the AC gravity replica experiment of the Basic Science Center of Capital University. It was the first time he saw the AC gravity experiment, and he was a little shocked when he found that the balloon suddenly floated up.

He only read some information about it.

Others in the lab have seen it once, and they are more concerned with detection parameters.

Soon someone reported the value, "Roughly estimated, our gravity has been reduced by about 2%!"

"Continue to experiment!"

"Cool down again!"

"Increase the transmission power!"

After Wang Hao heard the value, he issued several orders in a row, and the others also got busy.

Soon another data was calculated, "The gravity has been reduced by more than 2.3%."

"continue!"

Looking at the data shouted out one by one, Fan Qingxue was stunned. It was the first time for him to watch the communication gravity experiment live, but he had seen relevant materials.

In the AC gravity experiment conducted by the Basic Science Center of Capital University, the final value of reducing gravity is between 1.7% and 1.8%.

This value is already higher than the report of the physics laboratory.

Now it has increased to more than 2.3%, and the increased value 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 if it could reach the level of the capital university's replica experiment at that time.

This level of improvement is difficult to explain the problem, and it is necessary to do several experiments in a row to determine the influencing parameters.

The other two superconducting institutions are doing the same.

The first experiment in the physics laboratory was to increase the value by more than 0.5%. With such a huge improvement, some influencing factors can be determined even through only one experiment.

Such an experiment is worth several experiments.

Fan Qingxue felt that it was very unscientific. There was such a big improvement in the first experiment?

In addition, he did not understand the theoretical meeting, but he felt that some conclusions were drawn hastily, as if they were just for analyzing the greatest possibility, rather than rigorously using experiments to rule them out.

Fan Qingxue also felt that the people in the physics laboratory had a surprising "worship" for Wang Hao, which could even be described as "fanaticism". As long as it was what Wang Hao said, no one would question it.

The theoretical meeting is Wang Hao's talk.

In the case of so many problems, when it really entered the experiment, the effect was so good that it increased by more than 0.5% all at once?

Fan Qingxue stood and watched, not knowing what to say.

He found that his feelings were very similar to the first time he participated in a superconducting experiment. He didn't know what to do, and he didn't know why he came to the conclusion.

What happened in front of him was beyond the scope of his knowledge and experience.

finally.

The intensity of the AC gravity field has increased to 2.5%-2.6%, which is about 0.9% higher than the experiment conducted by the Basic Science Center of Capital University.

This major progress made everyone in the laboratory feel 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 give guidance to the physics laboratory, but he found that he was useless. He didn't even understand how to conduct a theoretical argument, let alone why. The effect of such an argument Can be so good.

"People do a comparative communication experiment, and a demonstration can greatly improve efficiency, but I even think that the demonstration is useless?"

"Is my thinking too backward?"

"The experimental results prove that they are scientific, and I am unscientific..."

When Fan Qingxue was thinking lonely, Wang Hao finished the summary of 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 an expert in superconductivity, and academician Wu Hui specially sent him to help.

Wang Hao made a gesture of invitation, and said, "Professor Fan, you are a professional superconductivity expert, so please come and tell us, or give us some advice."

Everyone looked forward to it.

Fan Qingxue was stunned for a long time with his mouth half open, and finally said, "Your laboratory is perfect."

"I feel like there's nothing left to say."

That night, Fan Qingxue flew 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 here and asked, "Didn't I ask you to guide the physics laboratory? Why did you come back so soon? How are they doing?"

"..."

Fan Qingxue held the documents in his hand, raised his head and didn't speak for a long time.

Finally, he sighed and said, "Professor Wu, I went to Xihai University, and I feel that my level is still far behind."

"So when I came back, I wanted to read more materials, increase knowledge, and learn."

"As for guidance..."

Fan Qingxue paused while talking, and smiled wryly, "How can I be qualified to guide them at my level, I have been guided..."
