Wang Hao re-examined the content on the whiteboard, and then turned his head with a helpless expression.
He felt that the explanation was detailed enough.
This is just a calculation and analysis method, not a proof of the effectiveness of the method. The difficulty of the two is not at the same level at all.
Li Jianhua and the other three felt very embarrassed.
Zhao Xindu didn't want Li Jianhua to speak. The two of them could still understand part of it, but only less than a third of the first part, and they couldn't keep up with the rest.
They naturally knew why Li Jianhua couldn't understand it, because there was a lot of profound mathematical content at the beginning.
Later, it involves very advanced discrete mathematics, functional analysis, etc., and it will be difficult for them to keep up.
Li Jianhua was embarrassed for a long time.
He discovered that he had estimated the difficulty level wrong.
I know it after thinking about it.
That is the analysis of a system of partial differential equations, and in the system of partial differential equations, there are two NS equations that cannot be solved. Even if you want to analyze it, it is very difficult, let alone find the approximate solution of the entire system of partial differential equations.
Already.
This difficulty is several levels higher than analyzing a single NS equation.
Li Jianhua took a deep breath and asked, "Professor Wang, like the system of equations that Cui Xunnian brought over, how long will it take you to use this calculation method to solve a set of approximate solutions?"
Wang Hao thought about it carefully and said, "I first found six ungroups, and then performed transformation analysis on each ungroup. Each ungroup was converted three times. It would be too complicated to continue."
"If it is a set of approximate solutions, it will take about four to six hours to convert three times."
He said and shook his head.
In this method of continuing to obtain approximate solutions, each analysis will be more precise, and the calculation and analysis involved will be more complex. It can even be said that the difficulty increases exponentially.
The second conversion takes more than twice as long as the first conversion, and the third conversion takes more than twice as long as the second conversion.
Most of his calculation time was spent on the third conversion, so he did not continue the conversion.
Mainly because it feels like it takes too long and doesn’t improve much.
Four to six hours doesn't sound like a long time, but if you think about it carefully, considering Wang Hao's level of ability and the method he created himself, it would still take a few hours.
If someone else used the same method, how many days would it take?
Dozens of days?
"It doesn't matter how long it takes, the key is to be able to make it!"
"But the main thing now is that I don't understand..."
Li Jianhua looked at Wang Hao thoughtfully and said, "Professor Wang, let me tell you straight. It is too difficult for us to understand what you are talking about here."
He was a little frustrated when he spoke, but he continued, "Professor Wang, do you have time? Can you come to our institute to give a lecture? Your research is really important to our aircraft design."
"Of course, I will definitely report the matter. Your research is still your research. We will also help summarize it."
"Don't worry about the lecture. I've seen the application from the Institute of Materials Science and Technology. It seems to be half a million, right?"
"no problem!"
Li Jianhua gritted his teeth and said, "We also offer half a million!"
He had some confidence when he said that the lecture fee was 500,000 yuan. If he had not applied for the Institute of Materials Science and Technology, let alone 500,000 yuan for the lecture fee, even if it was only 200,000 or 300,000 yuan, he would not dare to guarantee it.
However, having already had a ‘record’ from the Institute of Materials Science, the situation is different.
Wang Hao went to the Institute of Materials Science and Technology to give a lecture and received a lecture fee of 500,000 yuan. He also received unanimous praise from everyone in the Institute of Materials Science and Technology, including experts from Wuhan Iron and Steel Co., Ltd. who gave absolute affirmation. The evaluation of the Polymer Laboratory was also good.
Now Wang Hao is invited to give a lecture at the Aircraft Design Institute. With the report from Institute 103, it goes without saying that Wang Hao’s research is important to aircraft design. The aviation group will have a toothache, but it will eventually be approved.
If it is not approved, someone will say, "It is also Professor Wang Hao's lecture. Why can the Institute of Materials Science and Technology approve it, but our Shencheng Aircraft Design Institute cannot?"
In short, Li Jianhua is very confident.
When Wang Hao heard that there was a lecture fee of 500,000 yuan, he still hesitated, "It's not that I don't want to go, but I have an experiment to do recently."
"How about this!"
He thought about it and said, "I'll take a look at the beginning of next month. I'll go there if I have time."
"Okay, then it's settled." Li Jianhua was really anxious. He couldn't wait to understand the calculation method, but he couldn't be anxious about this kind of thing. After all, it was a very complicated calculation and analysis method. He might not be able to fully understand it after it was explained.
It takes some time to understand and then apply it.
And he also wants to summon more experts in aerodynamics and fluid mechanics to learn together.
Five hundred thousand cannot be spent in vain!
After Wang Hao finished talking, Li Jianhua and the other two walked out of the computer laboratory building together. While they were looking forward to Wang Hao's lecture, they also felt a little depressed.
Zhao Xin's feeling is more obvious. They specialize in appearance design calculations, but now they feel that it is too difficult to do research.
Looking back at history.
Hundreds of years ago, craftsmen did not need culture at all, they only needed experience and craftsmanship.
Later, in the era of the Industrial Revolution, if you understand some engineering, you can become an outstanding technical research and development personnel.
Later, that is, decades ago, there was a professional aerodynamics expert in the aircraft shape design project, who was very impressive.
Nowadays, fluid mechanics experts and aerodynamics experts are standard equipment. They think they are already very advanced in the industry, but they find that they are likely to be eliminated in the future.
Their level is still far from enough!
According to the mathematical analysis and calculation method explained by Wang Hao, not only aerodynamics professionals are needed, but experts in the field of partial differential equations are needed, and they also need to be proficient in mathematical analysis...
That is a very good mathematician!
Both Zhao Xin and Zhao Xin felt that they had been eliminated by the times, and they were filled with emotions.
But there is no doubt that Wang Hao's research is very important for aircraft appearance design. They are specialized in this research, and the aircraft appearance is designed based on the calculation results of the power pack.
Therefore, the method must be learned, otherwise the problem will not be solved at all.
The three of them returned to the team together.
At this time, the team had visited the NanoVis laboratory and was walking around the campus, not knowing exactly what they were going to do.
Xia Guobin awkwardly led the way. Fortunately, there were Zhu Jianhua, Yang Haiyan and others beside him, so he couldn't help but complain, "This team is here purely for Wang Hao. It has nothing to do with our Navitas laboratory."
."
"They didn't tell me in advance, so I don't know."
Yang Haiyan said, "We just try our best to entertain them."
Zhu Jianrong said, "Didn't your NanoLab apply for a project from the Institute of Aeronautical Materials? The Aircraft Design Institute and the Institute of Materials also have some relationship..."
"I think so too." Xia Guobin said and shook his head.
The three of them, Li Jianhua, found the team on the road, and then several people from the school came over to chat.
After exchanging pleasantries, several people followed him around the campus.
After having dinner at the school restaurant at noon, they were about to leave. Before leaving, Xia Guobin couldn't help but ask, "Designer Li, do you think our NanoLab's project with the Institute of Aeronautical Materials will be successful?"
Any chance?"
"this……"
Li Jianhua didn't know the situation at all. He couldn't take charge of the Aeronautical Materials Institute, and he didn't go to the NanoVis laboratory. He could only say, "I'll ask you later."
This is a very insincere statement.
Xia Guobin could only continue to sigh. He thought about it carefully and found that the aircraft design team he was looking for was completely irrelevant. It was better to ask Wang Hao directly.
Wang Hao knows many people in the Institute of Materials Science and Technology, including big shots who can make project decisions.
…
Wang Hao doesn't care about NanoLab's bidding projects.
Now he is concerned about the replica experiment in the physics laboratory. The preparation of the experiment will take about more than a week.
On this day, all the materials were in place and the experimental preparations were almost completed.
Wang Hao went to the laboratory in the morning and asked about the experimental problems, "How are the preparations going, Professor He?"
"It's almost done."
He Yi was busy with the work at hand, "We designed the experiment based on the research to arrange the superconducting material parts in a spiral structure, but this will cost more..."
He sighed and said with a wry smile, "If we don't find it this time, our project will be over."
The project I applied for last year was expected to be funded for three years, but the funding was exhausted in just over a year.
After completing such a project, it will probably be difficult to apply for other projects.
He Yi is still very stressed.
Wang Hao smiled and said, "Let's think on the bright side, what if the experiment finds something? I feel that there is no problem with our theoretical research. If there is still no discovery, maybe the communication gravity theory is wrong?"
"This should be considered the result, right?"
"What you said makes sense." He Yi thought about it carefully and said, "If the experiment fails and there are no other findings, we will report it like this."
"Ha ha."
The two chatted and laughed and continued preparing for the experiment.
The difficulty of superconducting experiments also lies in the preparation of superconducting materials. They use iron-based superconductors. The main difficulty lies in lowering the temperature. In the process, a lot of liquid nitrogen and other means are used to maintain ultra-low temperatures.
This is also the part that consumes the most money.
The reason why superconducting technology is difficult to apply on a large scale is precisely because it is difficult to reduce the temperature.
Even for high-temperature superconducting materials, it is necessary to create an environment of about minus 200 degrees Celsius, which is obviously very difficult.
We prepared for several hours that day, and it wasn't until 2pm that we were sure everything was ready.
People involved in the project in the physics laboratory gathered around the experimental hall.
Experimental equipment is installed in the middle of the hall. The core is the superconducting material spirally wrapped in the middle and the power supply device next to it. The pipes built around the equipment are all used to transport liquid nitrogen for cooling.
Testing instruments are installed on the edges, above and inside the experimental equipment.
A group of people gathered around for a long time, but no one said anything. Wang Hao asked He Yi, "Can we start?"
He Yi pursed his lips, as if he had made some important decision, and took a deep breath before saying, "Let's get started!"
This is indeed a very important decision for a physics laboratory.
An experiment only lasts for ten or dozens of minutes, and the preparation work takes a long time. It costs hundreds of thousands of dollars, which is also the last money they spend on the project.
Wang Hao didn't feel anything at all. It only cost hundreds of thousands of dollars. Of course, major experiments would cost a lot of money. Isn't it normal?
The experiment officially begins.
Two associate researchers are responsible for the experimental operation, including Yan Jing, who is responsible for recording and checking data, and several postdoctoral fellows, who are responsible for maintaining the normal operation of the liquid nitrogen delivery device to ensure that the experiment can proceed smoothly.
He Yi, Xiao Xinyu and Wang Hao stood nearby and watched.
After the experiment officially started, they all couldn't help but hold their breath and glanced at the balloon above the equipment disk.
In order to observe the phenomenon of exchange of gravity, they prepared a balloon with a density very close to that of air, placed it above the disk, and floated there most of the time.
If the phenomenon of exchange of gravity occurs, upward air movement will be formed, that is, wind force. Even if the gravity is only reduced by 1%, the balloon will rise.
This is a phenomenon that can be seen with the naked eye.
Of course, it is not just the balloon that is responsible for the detection, but also a small smoke-generating device. There is no wind in the laboratory, and every researcher also wears a mask to try to keep the air inside as still as possible.
When the smoke blown out reaches the top of the disk, if the phenomenon of exchange of gravity occurs, the route will definitely change, and they can make calculations based on the change in route.
In addition, there are two detection devices, and the effect can also be seen from the parameters.
finally.
With a buzzing sound, the equipment was officially started. Liquid nitrogen was continuously filled into the inside of the superconducting material tube, and the temperature inside was continuously decreasing.
When a certain critical line is reached, everyone looks at the balloon in the middle, hoping to see a miracle happen.
Everyone held their breath.
One second, two seconds, three seconds... More than ten seconds passed, but nothing seemed to change. Some people had already given up.
At this time, I found that the balloon was rising little by little.
Suddenly.
Everyone's eyes widened, including Wang Hao. Even after completing research, he had never been so excited.
What is happening before our eyes is a phenomenon that is truly happening at the cutting edge of science and technology.
Communicating gravity is, to put it bluntly, anti-gravity.
This is an incredible phenomenon.
When he actually saw the phenomenon happening before his eyes, he couldn't help but feel very excited.
The balloon rose little by little, not very fast.
Even so, many people were obviously excited. He Yi and Xiao Xinyu's cheeks turned red, but they still held back their words and just looked at the balloons.
Soon, the smoke generator started.
The smoke visible to the naked eye sprayed out in a straight line, and when it reached the top of the disk, the route changed slightly.
That kind of change is not big, but it still makes many people exclaim, "The route has changed, it has changed!"
"Did you see it? Did you see it?"
"The balloon also rose just now."
"Our experiment was successful, right? The experiment was successful! Anti-gravity really happened..."
"This is true or false!"
When someone exclaimed, everyone couldn't help but get excited and shouted excitedly.
He Yi couldn't help but hugged Wang Hao, "Did you see that? Professor Wang! We succeeded! We succeeded!"
"There really is a phenomenon of exchanged gravity! It's anti-gravity!"
Xiao Xinyu couldn't help but be excited. He shouted, "This experiment was carried out by the Academy of Sciences to no avail, but we succeeded."
"It must have been a success!"
Wang Hao also felt very excited, as if he saw a miracle happening before his eyes, and his eyes flashed with incredible light, "It should be a success, just like our judgment."
"The phenomenon of AC gravity exists, and anti-gravity exists!"
Everyone was very excited, and only those involved in the experiment were still suppressing their excitement and continuing with the work at hand.
They were obviously very excited. You could see that the pen in Yan Jing's hand was shaking, and the two people in charge of the liquid nitrogen device pursed their lips vigorously.
The experiment lasted twenty minutes, which was longer than expected.
Because the experiment was successful, they didn't care about consuming more materials. They still wanted to continue to verify and see how long this phenomenon could last. They found that it could continue forever.
It's just that the balloon didn't continue to rise, but stopped after reaching a certain position.
This is a very important phenomenon, and it is probably related to the propagation intensity and coverage of the AC gravity field.
Finally, the experiment is over.
All the equipment was stopped, and He Yi suppressed his excitement and said, "Quick, quick, quick, write down all the data!"
"Everyone, keep going!"
"Look at the detection parameters, we need timely data!"
Everyone immediately became busy.
But this time, everyone was very motivated because their experiment was successful, and they suppressed their excitement while doing follow-up work.
This is definitely a major discovery.
Although it is not an innovative research, because there are very few internationally publicized data, the replication experiment is also very meaningful.
Wang Hao stood aside and did not participate in the experimental work.
He wants more.
The phenomenon of AC gravity is actually anti-gravity. Even if the gravity is only reduced by one percent, it is a qualitative change from 0 to 1.
Now it is just a replica of foreign experiments, but it is still very meaningful. Regardless of whether the research can have follow-up, at least it will not lag behind others in anti-gravity research.
Regarding the experimental project, he was not as excited as the people in the physics laboratory, because whether the project was successful or not had no impact on him.
…
The final experimental data was that gravity was reduced by about 1.5%.
According to internationally published data, the value of reducing gravity is 2~3%, but it is difficult to say whether the data is true because there are no subsequent relevant reports.
Even if gravity is only reduced by 1%, it is a breakthrough from 0 to 1, which also illustrates the success of the replica experiment.
This is enough.
After the experiment was over, everyone in the physics laboratory was taking notes, and their project no longer needed to be continued.
One is because there is no financial support.
Secondly, because the results have been achieved, as long as the information on the exchange of gravity experiments is reported, it can be said that the project has been completed perfectly. The subsequent acceptance, summary and analysis will not only involve the physics laboratory.
He Yi and Wang Hao talked about this issue, "The next step is to submit the report and accept it. I estimate that I can get follow-up support and apply for a relevant large project."
"but……"
"It's possible that you won't be able to apply." He said with some bitterness, "Maybe other superconducting research laboratories will rely on this result to carry out follow-up research, but the equipment and personnel of our laboratory are still too far behind."
This is a very embarrassing and depressing question.
The physics laboratory has completed a replica experiment of AC gravity, but they are not necessarily able to apply for follow-up research projects based on this experiment.
On the contrary, other capable laboratories, such as the Superconducting Laboratory of the Academy of Sciences, can continue to carry out follow-up research based on their results.
Wang Hao smiled and said, "You don't have to think too far ahead. After you have this result, it will be much easier to apply for other projects."
"It's true." Xiao Xinyu said, "Old He, you don't need to think too much. An experimental discovery is better than nothing. We have successfully replicated this experiment. Even if we get to the Academy of Sciences in the future, we will still have face."
"The superconducting laboratory of the Academy of Sciences didn't even make it!" He Yi laughed at the thought, "I still have to thank Professor Wang. Your theoretical analysis is really professional."
"If it were us, we would have hastily conducted experiments and spent all the funds carelessly. Now we have succeeded in one go."
"Professor Wang, don't worry, you are the leader in this research!"
"That's no need."
Wang Hao shook his head. After witnessing the success of the experiment, he also began to think about his own research problems.
The reason why I participated in this experiment is mainly because the experiment is related to the study of annihilation force.
However, during the entire experiment, he did not notice where the annihilation force was reflected, nor did his inspiration value increase at all.
This is what makes Wang Hao puzzled.
He felt that there must be something that he had overlooked or hadn't thought of.
On the way back, Wang Hao was thinking about this problem. He suddenly thought of the physics laboratory meeting that day, where everyone explored the principle of communication gravity.
"Is it related to the ion lattice spin? However, theoretical research has not brought much inspiration."
"Or the experiment itself? How does the phenomenon of AC gravity occur? Why does it happen..."
"Is it gravitational isolation, or space oscillations, ripples?"
Wang Hao suddenly felt that he had found the direction, and continued to think deeply, "The ion lattice arranges the spins in a certain way, creating an AC gravity field. The phenomena that occur in the field are caused by the reaction in space."
"And the reaction of space can affect objects, which itself proves that space can have an effect on objects, not just objects causing ripples in space to form gravity!"
"This causal relationship itself is directly related to the force of annihilation!"
…
The AC gravity experiment in the physics laboratory is completed.
Wang Hao had made the progress he wanted and already had ideas for the next step. He also confirmed the time for the lecture with the Aircraft Design Institute.
He had no intention of doing further research quickly. It involved constructing a theoretical system of physics, which was very, very complicated and would be a huge task. He had better read the data to enrich himself first.
Including string theory, cosmology, and the Big Bang theory, you can take a look at the related mathematical frameworks and refer to them.
In this process, Wang Hao also felt that he had gained a lot.
The day before going to Shencheng Aircraft Design Institute, Wang Hao was still reading the information. He was studying seriously, but he seemed very leisurely.
He was crossing his legs, drinking coffee, and just looking at something seriously.
People in the office are all discussing thesis issues.
Sun Jian recently published a mathematics paper, which made Zhu Ping feel very envious and a little inferior.
As the eldest lady in the office, she is working hard to study for a Ph.D., but she still studies most of the time. She can only mutter, "Old man Chen is really unreliable. Even if he asks me to study, study, study, he doesn't know how to lead me to do it."
do research."
"Don't worry, Academician Chen will definitely let you start doing research when you're done studying." Zhang Zhiqiang had a good impression of Chen Qinghua, so he still said a word of help.
Zhu Ping said depressedly, "Of course you don't have to worry, you are already a great professor!"
"Sun Jian is also a genius!"
"Luo Dayong is going to be promoted to associate professor, Wang Hao..."
She couldn't speak any more.
Zhang Zhiqiang said helpfully, "I just saw that from March last year to now, Wang Hao has published 35 SCI articles..."
This number silenced everyone in the office.
If you were a professor who had been working for more than ten or twenty years, it would be nothing if he had published more than thirty SCI papers.
But Wang Hao has only been working for more than a year.
More than a year is equivalent to more than ten years for others.
After hearing this, Wang Hao asked in confusion, "Is there only 35 articles?"
"..."
"..."
People in the office don't want to talk anymore.
Wang Hao did not emphasize the numbers intentionally, but he opened the system and found that the number of papers had reached 39.
If the number of sci papers is 35, the remaining four should be blog papers, or some other related summaries should also be counted as papers.
He suddenly thought of a question, "Yes, 39 articles!"
"With one article left, "The Gift of Teaching" will be upgraded!"
Wang Hao looked at Zhang Zhiqiang gratefully and said, "Brother Zhang, you reminded me that I happen to have a study related to Li Qun, but I don't have a summary. I will summarize it now and post it on the blog later."
"Why not issue SCI?" Zhang Zhiqiang was a little confused.
Wang Haodao said, "Submitting to SCI is a lot of trouble. You have to pay attention to the format, and you have to wait for review and publication. For small research, just post it on a blog."
Zhang Zhiqiang felt a little like crying.
People just can't compare. He worked so hard to publish a paper. In the end, Wang Hao didn't care at all and just posted the summary on his blog?
He raised his head and looked at Zhu Ping and asked, "Zhu Ping, why don't we discuss it and change seats? I feel that if I continue to sit here, my life may be shortened by ten years."
"No, no!" Zhu Ping hurriedly shook her head and said, "I sit at the door, and students always come to me. It's convenient."
After she finished speaking, she quickly sat down, as if she was afraid that Zhang Zhiqiang would steal her seat.
"Do you always have students coming to you?"
Zhang Zhiqiang thought about it carefully and asked Luo Dayong with doubts, "Have you ever seen any students come to see her?"
Luo Dayong turned around and said, "Since you know, why do you still ask?"
"ah?"
"No one wants to sit with a genius. So in our office, Zhu Ping is the most popular."
"Oh, that's right!"
Zhang Zhiqiang glanced at Wang Hao and expressed strong agreement, "Zhu Ping is indeed the most popular, she is the stupidest."
I don’t know when, Zhu Ping stood beside the two of them, still holding a rolled-up book in her hand, staring at Zhang Zhiqiang with gritted teeth, "Zhang! Zhi! Qiang! What did you say? Who is the stupidest?"
"ah?"
"Sister Zhu, Luo Dayong said it, it's none of my business~~~"
