The preparation for this experiment is much more complicated than before. The requirements for temperature adjustment and detection are higher, so the experimental design, process, and control must be more precise.
In addition, the experiment used an iron-based alloy superconductor, and the superconducting excitation temperature is only about 20K (Kelvin). It is necessary to create ultra-low temperatures below minus 250°C, which is several times more difficult.
"It's best to have a large device that controls the temperature accurately."
Xiang Qiansheng said, "To conduct this experiment with our current equipment, the experimental design will be very complicated and the accuracy is not enough."
Wang Hao thought for a while and asked, "The accuracy is almost acceptable. I just want to see the phenomenon."
He Yi sounded a little distressed, "This experiment will probably cost a lot of money."
"Don't worry about the funding." Wang Hao did not consider the funding issue. As long as it is within the normal cost range, it is acceptable. Even if it costs more, a few million for one experiment is enough.
Xiang Qiansheng thought for a while and then suggested, "Professor Wang, are we going to do experiments like this in the future? If we do a lot, I still recommend purchasing a large-scale equipment that can accurately control the temperature."
Wang Hao asked, "How much does it cost to buy such a piece of equipment?"
"Money is not the key."
Xiang Qiansheng said, "This kind of equipment is imported and ordered from a fixed manufacturer. It takes a long time from ordering to manufacturing, transportation and debugging. This kind of equipment can be delivered in one year, which is already very fast." Soon."
He continued, "If it is used a lot in the future, we can purchase it from other laboratories. The Superconducting Laboratory has an idle temperature control equipment, and it has been idle for more than two years. Their projects cannot use it temporarily."
"How much does it cost?" He Yi immediately asked. It is good to buy second-hand top-notch scientific research equipment, but the main reason is that the price of cutting-edge equipment is too high and ordinary laboratories cannot afford it.
"It will cost more than 30 million."
Xiang Qiansheng thought for a moment and gave a figure, then explained, "The introduction of that equipment cost 60 million. Although it has been used for many years, it only cost 30 million, and the Superconducting Laboratory is not willing to sell it. "
Top-notch scientific research equipment is not an ordinary electronic product.
The market for this kind of cutting-edge equipment is small, and only large laboratories will buy it, but again, it is difficult to buy it.
Wang Hao nodded and said, "Let's prepare this experiment first. If the results are in line with expectations, we will then consider purchasing new equipment."
After the meeting ended, everyone in the laboratory became busy.
This is a large experiment.
It took more than a week to prepare for the experiment. Without purchasing new equipment or materials, every part of the experimental device was built by hand, and even the circuits inside were connected one by one.
After everything was ready, everyone gathered in the operation room and prepared to officially start the experiment.
Everyone's face was filled with tension and anticipation.
This is a very large experiment, not because of how large the scale is, but because the requirements for the experiment are too high and the corresponding costs are also very high. The total cost of the experiment is more than five million.
The previous experiments they conducted had a maximum cost of only 600,000 or 700,000.
In addition, the goal of the experiment is also very interesting. It is hoped to detect the AC gravity field phenomenon before the superconducting state is excited.
"If the superconducting state is not excited, will an AC gravity field be produced?"
"This is what Professor Wang said. It should be okay, right? I don't believe anyone, but I also believe Professor Wang."
"But it still sounds unreliable."
"If the AC gravity field can be detected without exciting the superconducting state, doesn't it mean that it is possible to activate the AC gravity field at room temperature and normal conductivity?"
"Now we are creating ultra-low temperatures, are you thinking too far ahead?"
Many people were discussing in low voices.
They were indeed very curious about the experiment, as were Liu Yunli and the other three. They felt as if they were about to witness a miracle.
People in the physics laboratory have great trust in Wang Hao, and it can even be said that they are fanatical. They have not reached this level yet, and they still feel that it is impossible to achieve anti-gravity in a non-superconducting state.
Wang Hao stood in front of the experimental equipment, stared at it for a long time with his lips pursed, and then waved his hand, "Let's get started."
Then he stepped aside and watched.
Although the experiment is very expensive and requires higher detection accuracy, the experimental process is no different from the original one.
The experiment is to continuously lower the temperature after power is turned on. After it drops to minus 150°C, the speed begins to slow down.
When it drops below minus 200°C, the rate of decrease becomes even slower, and the value also drops a little bit. The superconducting temperature of the iron-based superconductor used in the experiment is minus 259°C.
When the temperature reached minus 250 degrees Celsius, everyone looked carefully at the logo - ultra-thin balloon.
Several ultra-thin balloons are suspended directly above the device. The average density of the balloons is almost the same as that of air. Because the top and sides are isolated by glass covers, there is no air flow inside, and the balloons will not rise.
The temperature is still slowly dropping.
-
251℃.
-
252℃……
When it reached '-253°C', the balloon in the glass cover suddenly slowly rose upwards.
Although it only rose a little, the operation still caused a burst of exclamation, because the temperature has not yet reached the critical line of superconductivity.
The temperature continues to drop.
-
253℃.
Several balloons have been attached to the top of the glass cover. Other detection equipment has also changed its values. The pointer that detects the AC gravity field value has also deflected slightly.
Everyone was very excited, but everyone held their breath.
The experiment continues.
The final temperature reached minus 259°C. When the superconducting state was activated, the detection pointer suddenly deflected significantly.
But it's no longer important.
"That's it!"
Wang Hao's voice was also slightly excited. The theory he studied was verified again, which showed that his research direction and conclusions were correct.
The people participating in the experiment are still carefully recording the data.
Others couldn't help but excitedly discuss, "Is this a brand new discovery?"
"It turns out that stimulating an AC gravity field does not necessarily have to be in a superconducting state. Ordinary conductive states are also possible..."
"It may also be that in the ordinary conductive state, the AC gravity field is so small that it cannot be detected? It is completely covered by the electromagnetic field?"
"The AC gravity field may also be related to the electromagnetic field?"
"Anyway, this is definitely a big discovery! A super big discovery!"
Liu Yunli, Ruan Weiping and Xue Chang were also very shocked. They also knew that they were definitely making a big discovery in front of them.
They are only technically studying the AC gravity field, but no matter how much they study technically, it is impossible to make such a discovery.
The three of them were silent together.
Xue Chang said, "So I have always felt that our research is meaningless."
"It's better to move here quickly!"
"With the help of Professor Wang's theoretical research, we can find the direction of improvement in technology..."
Ruan Weiping pursed his lips and said, "You can apply for the move here first, but I think it's more important that we study Wang Hao's annihilation and topology theory."
"If we don't understand this, we'll never catch up."
Liu Yunli and Xue Chang nodded together. They had not paid attention to the 'annihilation topology theory' before, but now they finally discovered that the 'difficult to understand' theory mentioned by Wang Hao was the most important.
If they cannot understand the basic theory, they can only follow and watch, and it is impossible to truly participate in the research.
…
After new discoveries are made, the laboratory still summarizes data and summarizes experiments.
Wang Hao began to do further research. He encountered a bottleneck in his topological research on microscopic morphology within conductors.
But soon, good news came.
Lin Bohan officially resigned and came to Xihai University, signed an agreement to become an associate researcher at the Mason Number Laboratory, and also joined the exchange gravity research project of the Physics Laboratory.
Lin Bohan's resignation was not easy, mainly because the Mathematical Sciences Center attached great importance to him.
There are many postdocs working in the Mathematical Sciences Center. Lin Bohan is not the best among them, but he is very promising.
One is because he is a doctoral student from Shuimu University.
The second reason is that his field is geometric topology and he has published a top-ranked paper.
This is amazing.
A top-ranked paper seems to be nothing. In fact, the content of the publication also needs to be distributed. Topology is a minor subject of mathematics. There are very few scholars engaged in geometric topology research, and the research threshold is also very high.
When he was about thirty years old, he published a top-level paper in a related field, which can be classified as a "rare talent".
Qiu Chengwen valued Lin Bohan very much. He knew that Lin Bohan was going to Xihai University, and he almost burst out with an angry curse directed at Wang Hao.
He had a stubborn temper to begin with, and he gasped in anger when he heard the news.
Finally, Lin Bohan was invited to have a face-to-face talk.
Lin Bohan said that he wanted to do research with Wang Hao, and Xihai University's salary was very good, he could directly participate in large projects, and he didn't have to worry about funding. He couldn't even find a reason to refuse.
He wanted Qiu Chengwen to think of a reason for him, but Qiu Chengwen couldn't think of any.
The conditions of Shuimu University are indeed good, but because there are so many talented people, the treatment that can be given to Lin Bohan will definitely not be as good as that of Xihai University. It is not even possible to directly hire an associate researcher, not to mention the funding, which is basically impossible.
of.
It is true that good universities have a lot of funding, but high funding has nothing to do with the bottom class. Ordinary scholars still have to apply for it on their own, and at most they can get a little subsidy.
Even scholars from the Mathematical Science Center must apply for the outstanding youth and outstanding youth projects themselves.
The funding for these projects is very intense, and the subsidy rate has long been below ten points. It is very difficult to get approved for pure mathematics research.
If it is a major category of mathematics, such as the field of partial differential equations, it is relatively easy to apply for funding. Topology research is one of the most difficult fields to apply for funding. Many people even believe that algebraic geometry and topology research have nothing to do with reality.
If there is any relationship, the research will have no practical significance.
Qiu Chengwen could only say with depression, "It's better to go to Wang Hao. Wang Hao is the best mathematician. He is very thoughtful and capable. He has already surpassed me."
"He asked you to go by name, so you don't have to worry about the treatment."
"Xihai University lacks talents, and you will be more valued there..."
Then Lin Bohan came.
Wang Hao really attaches great importance to Lin Bohan.
After Lin Bohan officially joined the company, he immediately took him to do research together, "Dr. Lin, you are here at the right time!"
"I'm having a headache with my research."
He pulled Lin Bohan and started talking, "I am studying a geometric problem similar to microscopic morphology. This microscopic morphology, after undergoing topological phase transformation, will form a two-dimensional infinitely extending shape..."
Wang Hao spoke carefully.
His imagination of the microscopic shape within a conductor is like an irregular sphere, with both sides of the sphere open.
In imagination, the microscopic form is a special sphere, but its real structure is not like this. Several requirements must be met.
One is that after extrusion, the "special force field" wrapped inside will escape, or it will affect the microscopic applications in the central channel, forming an exchange of gravity.
The second is its topological form, which is an infinitely extending two-dimensional cylindrical plane. The two-dimensional cylinder is not perfect. There will be some holes in the middle. The cylinder itself will not affect the microscopic motion.
Third, any two straight lines on the surface of a special sphere will intersect. At the same time, due to its topological shape, any two straight lines are parallel and do not intersect.
The last point is the most difficult to satisfy, and the research also involves complex geometric analysis.
This special geometric requirement is directly related to the nature of the microscopic morphology within the conductor.
Wang Hao believes that the microscopic morphology within a conductor is directly related to the electromagnetic force, or in other words, the microscopic morphology determines the electromagnetic force.
In the special state of superconductivity, the topology of the microscopic morphology results in a conductor in the superconducting state that is no longer affected by electromagnetic force (this has been confirmed).
In addition, there is a direct relationship between microscopic morphology and AC gravity field. Some microscopic morphologies are more complete and more difficult to topologise, which means that the requirements (temperature) to activate the superconducting state are higher.
On the contrary, it is a high-temperature superconducting material.
Lin Bohan suddenly felt a little incomprehensible after hearing what Wang Hao said, "In the concept of topology, there is no concept of size. The infinitely extending two-dimensional cylindrical plane should be discussed in terms of geometric directions."
"Perhaps it can also be understood as 'directional topology'?"
"If we study the original form of topology, we can create a brand new geometric space..."
Lin Bohan said that his main direction is geometric topology, but he has some experience in Euclidean geometry and Riemannian geometry. "If it is to create a new geometric space, the definition must be more rigorous."
Wang Hao asked, "How to understand a specific three-dimensional geometric space where any two straight lines intersect?"
"This is easy!"
Lin Bohan wrote down the definition and made a graph, and then the two of them discussed it together.
…
It is indeed a very interesting task to define a new geometric space according to the actual needs of research.
Geometry is not fixed.
The geometric theorems in primary and secondary school textbooks are just the foundation among the foundations. Once you truly enter the field of geometry, all conventional definitions and axioms become ordinary basic definitions.
For example, the famous Riemannian geometry.
A basic definition of Riemannian geometry is that any two straight lines in the same plane have a common point (intersection).
The existence of parallel lines is not recognized in Riemannian geometry. Another postulate of it says that straight lines can be extended infinitely, but their total length is finite.
These definitions obviously go against common sense.
However, Riemannian geometry is the mathematical foundation of general relativity. At the same time, Riemannian geometry is also a very important tool in mathematics. It is not only the basis of differential geometry, but also used in differential equations, variational methods, and complex variable function theory.
The current work done by Lin Bohan and Wang Hao is to try to define a new geometric space so that it can meet the research needs.
To this end, Wang Hao also set up a task of "research on the internal microscopic morphology of conductors"——
【Task 1】
[Research Project Name: Research on the Internal Micromorphology of Conductors (Difficulty: S).]
[Inspiration value: 17.]
…
When you are really involved in a research that you are very interested in, time seems to become the least important thing.
Soon another two weeks passed.
This time point has become very important, because the International Congress of Mathematicians held in Austria is about to begin.
Domestic academic circles are paying close attention to this International Congress of Mathematicians.
A lot of people are paying attention to the awards.
Although it is said that Wang Hao will definitely win the Fields Medal, there is no 100% certainty as to whether it will be awarded to Wang Hao, and Wang Hao's award is obviously of great significance.
For one thing, he will become the first domestic scholar to win the Fields Medal.
Second, he will become the youngest winner in Fields history.
Both of the above points are very important.
Xihai University is not worried about winning the award, especially those who know the details, including Luan Haiping, Chen Qinghua, and other senior leaders of the school, they all know that Wang Hao will definitely win the award.
because……
The medals and certificates have been sent to Xihai University in advance.
The Fields Awards Committee attaches great importance to Wang Hao’s award.
They seemed to be afraid that Wang Hao would not accept the award, so they sent staff to Xihai University in advance. On the one hand, they wanted to deliver the medals and certificates, and on the other hand, they wanted to hold a simple award ceremony through video communication.
There were two staff members who came.
One is named Jin Xinian and the other is named Brown Brodbeck.
After they arrived, they received a warm reception from Xihai University. Even if they were just ordinary staff, but they came specially to deliver Fields medals, the treatment they received was definitely different.
Brown-Brodbeck was more focused on work. After he arrived, he wanted to talk to Wang Hao about receiving the award.
"Excuse me, where is Dr. Wang?"
"We need to talk about the award receiving process, or the communication process."
Jin Xinian explained, "Our job is not just to deliver medals, but also to ensure smooth communication. We wait until Dr. Wang finishes his report before leaving."
The school sent someone to find Wang Hao.
Wang Hao and Lin Bohan are doing research together. It can be said that they are modest even without leaving home. Their research is so crazy that they ignore time.
When he heard that the Mathematical Society had sent someone to deliver medals, he just waved his hand and said, "I paid attention to the time, isn't it tomorrow?"
The opening ceremony of the International Congress of Mathematicians is indeed tomorrow.
Brown-Brodbeck and Jin Xinian couldn't see Wang Hao, so they had no choice but to stay in a hotel for one night. But by the next morning, they still couldn't see Wang Hao.
Not only are they anxious, but also the people in the school are anxious as well.
This is the Fields Award Ceremony.
Even if he has definitely won the award, the process of awarding the award is still very important, because Wang Hao is likely to win the award, and there will be a live broadcast by the media, and many people will watch the live broadcast.
At eight o'clock in the morning, Luan Haiping called Wang Hao, and together with Chen Qinghua, Zhou Qingyuan and others, they quickly rushed to the restaurant and almost dragged him to the government affairs building.
In an office in the Government Affairs Building, everything is ready.
Wang Hao stood in the middle a little depressed, turned his head and saw the background of "a lot of mathematical symbols", which looked really good.
But it’s too deliberate!
"Actually, you don't have to worry. I have to pay attention to the time. It doesn't start until after nine o'clock. I also plan to go to the office..."
"It's already half past eight!" Zhou Qingyuan quickly emphasized.
Others still have to pay attention to their tone when talking to Wang Hao, but Zhou Qingyuan has no such scruples, "It starts in half an hour. We are all worried about you. What if you miss it?"
"Will not……"
Wang Hao said weakly. He was still thinking about the geometry problem in his mind. He really didn't care too much about the awards. He must have won the award anyway. He would just come over and show his face on the camera.
What follows is an anxious wait.
Others seemed more excited than Wang Hao, while Wang Hao felt like a groom about to get married, standing on the stage quietly waiting for the 'ceremony'.
Fortunately, the waiting time is not long.
The opening ceremony of the International Congress of Mathematicians was the award ceremony, and the first award awarded was the Fields Medal. It can be said that it reached a climax all of a sudden.
The screen next to the office showed the real-time situation at the scene, and the host shouted, "Next, the list of Fields winners will be announced."
"First of all, Lorscisco..."
"He was developing stochastic conformal mapping, the geometry of Brownian motion in two dimensions..."
"Elder Bhargava..."
"Alix..."
The host named three names in succession, and the mathematicians whose names were called came up to the stage respectively, received their medals and certificates, and also said a brief exclamation.
Then the host announced the last name, "I think everyone already knows it in advance."
"The last winner, Wang Hao!"
"Dr. Wang Hao has made outstanding contributions in the fields of number theory and partial differential equations."
"He proved the problem of the century, Goldbach's conjecture, and he solved the NS equation problem that is directly related to its application."
"At the same time, he also completed research on the Kakutani conjecture, the reduction of infinite series formulas, Monge's Ampere equation, etc..."
"This year's Fields Medal should be awarded to him of course."
There was fierce applause from the scene.
The host continued, "Dr. Wang Hao did not come to the scene, but we can contact him through video calls."
The big screen screen switched to the office in the Government Affairs Building of Xihai University.
Wang Hao was wearing casual clothes, with a symbolic background behind him. He stood in front of the camera, waved and said hello, "Hello everyone."
Brown-Brodbeck and Jin Xinian appeared together, handed over medals and certificates respectively, and also helped Wang Hao hang the medal around his neck.
When Wang Hao faced the camera again, he knew what he should say. He thought for a moment and said calmly, "Now, I feel very excited."
"The Fields Medal is the highest award in the international mathematics community and is very meaningful."
"Everyone knew I would win the award before, but actually even I didn't know."
"I went to have breakfast this morning, and I was pulled here to receive the award. What an unexpected surprise!"
"Thank you to the International Mathematical Society, thank you to Xihai University, and thank you all..."
After he finished speaking, he turned to look at the others, and what he said in his eyes was, "Is this okay?"
A group of people fell into collective silence.
The eyes and expressions they looked at seemed to describe a few big words, "Can you be more fake?"
