From University Lecturer to Chief Academician

The preparation for this experiment is much more complicated than before, and the requirements for temperature adjustment and detection are higher, so the experimental design, process, and control must be more precise.

In addition, an iron-based alloy superconductor was used in the experiment, and the superconducting temperature is only about 20K (Kelvin), so it is necessary to manufacture ultra-low temperatures below minus 250°C, which is several times more difficult.

"It is best to have a large-scale device with precise temperature control."

Xiang Qiansheng said, "To do this experiment with our current equipment, the design of the experiment will be very complicated, and the precision 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 felt distressed, "This experiment will probably cost a lot of money."

"Don't worry about funding." Wang Hao didn't consider the issue of funding, as long as it is within the normal range of expenses, it is acceptable, even if it costs more, a few million yuan is enough for one experiment.

Xiang Qiansheng thought about it, and then suggested, "Professor Wang, shall we do this kind of experiment in the future? If there are more experiments to be done, I still recommend buying a large-scale equipment with precise temperature control."

Wang Hao asked, "How much does it cost to buy such a device?"

"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 commissioning. This kind of equipment can be delivered within one year, which is already very fast." Soon."

He continued, "If we use it more in the future, we can buy 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 are temporarily unusable."

"How much will it cost?" He Yi immediately asked. It is also good to buy second-hand top-notch scientific research equipment, mainly because the price of cutting-edge equipment is too high for ordinary laboratories to afford.

"It should be more than 30 million."

Xiang Qiansheng thought for a while and said a number, and then explained, "The introduction of that equipment cost 60 million yuan. Although it has been used for many years, it is estimated to only cost 30 million yuan, and the superconducting laboratory is not willing to sell it. "

Top scientific research equipment is not an ordinary electronic product.

The market for such cutting-edge equipment is small, and only large labs buy it, but again, it's hard to find.

Wang Hao nodded and said, "Let's prepare for this experiment first, and if the results meet expectations, we will consider purchasing new equipment."

After the meeting was over, the lab was busy from top to bottom.

This is a large experiment.

It took more than a week to prepare for the experiment. Without purchasing new equipment and 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, ready to officially start the experiment.

There was tension and anticipation on everyone's face.

This is a very large-scale experiment, not to say how large the scale is, but because the demand for the experiment is too high, and the corresponding cost is also very high. The total cost of the experiment is more than five million.

The highest cost of their previous experiments was only 600,000 or 700,000.

In addition, the goal of the experiment is also very interesting. It is hoped that the AC gravity field phenomenon can be detected before the superconducting state is excited.

"Without exciting the superconducting state, would an AC gravitational field be produced?"

"This is what Professor Wang said, so it shouldn't be a problem, right? I don't trust anyone, but I also trust Professor Wang."

"But it still sounds unreliable."

"If the AC gravitational field can be detected without exciting the superconducting state, doesn't it mean that it is possible to excite the AC gravitational field under normal temperature?"

"Now we are making ultra-low temperatures, are you thinking too far?"

Many people are discussing quietly.

They were indeed very curious about the experiment, and so were Liu Yunli and the other three. They felt as if they were going to witness a miracle.

The people in the physics laboratory have great trust in Wang Hao, and it can even be said to be a kind of fanaticism. They have not yet reached this level, 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, pursed his lips and looked at it for a long time, then waved his hand, "Let's start."

Then he stepped aside to watch.

Although the experiment costs a lot and requires higher detection accuracy, the experiment process is no different from the original one.

The experiment is to continuously lower the temperature after the power is turned on, and the speed has already started to slow down after dropping to minus 150°C.

When it is lowered below minus 200°C, the rate of reduction is even slower, and the value also drops a little bit. The iron-based superconductor used in the experiment has a superconducting temperature of minus 259°C.

When the temperature reached minus 250°C, everyone took a serious look at the sign—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 the air. Because the top and sides are isolated by glass covers, there is no air flow inside, and the balloons will not rise upwards.

The temperature is still dropping slowly.

-

251°C.

-

252°C...

When it reached '-253°C', the balloon in the glass cover suddenly rose slowly.

Although it only rose a little bit, the operation still couldn't help but let out a burst of exclamation, because the temperature has not yet reached the critical line of superconductivity.

The temperature continued to drop.

-

253°C.

Several balloons have been attached to the top of the glass cover, and the values ​​of other detection equipment have also changed. The pointer for detecting the value of the AC gravity field has also slightly deflected.

Everyone is very excited, but everyone is holding their breath.

The experiment continued.

In the end, the temperature still reached minus 259°C. When the superconducting state was activated, the detection pointer suddenly deflected greatly.

But that doesn't matter anymore.

"Okay!"

Wang Hao's voice was also a little excited. The theory he studied was verified again, which showed that his research direction and conclusion were correct.

The people involved in the experiment are still carefully recording the data.

Others couldn't help discussing excitedly, "Is this a brand new discovery?"

"It turns out that it is not necessary to be in the superconducting state to excite the AC gravity field, and the ordinary conductive state is also possible..."

"It may also be that in a normal conductive state, the AC gravity field is so small that it cannot be detected? It is completely covered by the electromagnetic field?"

"Communication of gravity field, may it also be related to electromagnetic field?"

"Anyway, this is definitely a big discovery! Super big discovery!"

Liu Yunli, Ruan Weiping, and Xue Chang were also very shocked, and they also knew that there was definitely a big discovery in front of them.

They are only technically studying the exchange gravity field, but no matter how much they study technically, it is impossible to have such a discovery.

The three were silent together.

Xue Changdao, "So I have always felt that our research is meaningless."

"Let's 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 should 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 didn't pay attention to the "annihilation topology theory" before, but now they finally found that the "difficult to understand" theory mentioned by Wang Hao is the most important.

If they can't figure out the basic theory, they can only follow and watch, and it is impossible to really 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 the topology research of the microscopic morphology in the conductor.

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 Center for Mathematical Sciences attached great importance to him.

There are many postdoctoral fellows in the Mathematical Sciences Center, Lin Bohan is not the best among them, but he is very promising.

One is because he is a Ph.D. student at Mizuki University.

The second is because his field is geometric topology, and he has also published a top journal paper.

It's amazing.

A top-published paper seems to be nothing. In fact, the content of the publication must also be distributed. Topology is a small subject of mathematics. There are very few scholars engaged in the study of geometric topology, and the threshold for research is also very high.

At the age of 30 or so, he has published a paper in a top journal in a related field, which can be classified as a "rare talent".

Qiu Chengwen attached great importance to Lin Bohan. He knew that Lin Bohan was going to Xihai University, so he almost spewed out a curse against Wang Hao.

Originally, his temper was a bit stubborn, and he was gasping for breath when he heard the news.

In the end, 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 paid well, and he could directly participate in big projects without worrying 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 it either.

The conditions of Shuimu University are indeed good, but because there are too many talents, the treatment that can be given to Lin Bohan is definitely not as good as that of Xihai University, and it is even impossible to directly hire an associate researcher, not to mention the funding. It is basically impossible of.

Good colleges and universities do have a lot of funding, but the high funding has nothing to do with the bottom. Ordinary scholars still have to apply on their own, and at most they can get a little subsidy.

Even the scholars of the Center for Mathematical Sciences have to apply for the Excellent Young Scholars and Outstanding Young Scholars by themselves.

The funding for these projects is very intense, and the subsidy rate has been below ten points for a long time. It is difficult to apply 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 areas to apply for funding. Many people even think that the research of algebraic geometry and topology has nothing to do with reality. If there is any relationship, the research will have no practical significance.

Qiu Chengwen could only say with gloom, "It's good to go to Wang Hao. Wang Hao is the best mathematician, very thoughtful and capable, and 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 attached great importance to Lin Bohan.

After Lin Bohan officially entered the job, he immediately pulled him to do research together, "Dr. Lin, you came just in time!"

"I'm having a headache with research."

He pulled Lin Bohan and started to talk, "I'm studying a geometric problem similar to microscopic forms. This kind of microscopic form, after topological phase transition, will form a two-dimensional infinitely extending shape..."

Wang Hao spoke carefully.

His imagination of the microscopic shape inside the conductor is like an irregular sphere, with both sides of the sphere open.

In the imagination, the microscopic form is a special sphere, but its real structure is not like this, and several requirements must be met.

One is that after being squeezed, the 'special force field' of the inner package will escape, or it will affect the microcosmic application in the central channel, forming an exchange of gravity.

The second is its topological shape, which is a two-dimensional cylindrical plane that extends infinitely. The two-dimensional cylinder is not perfect, and there will be some holes in the middle, and the cylinder itself will not affect the microscopic movement.

The third is that any two straight lines on the surface of the special sphere will intersect, and at the same time, in its topological form, any two straight lines are parallel and do not want to intersect.

The last point is the most difficult to satisfy, and the research also involves complex geometric analysis.

This particular geometrical requirement is directly related to the nature of the microscopic morphology within the conductor.

Wang Hao believes that the microscopic shape in the conductor is directly related to the electromagnetic force, or in other words, the microscopic shape determines the electromagnetic force.

In the special state of superconductivity, the topology of the microscopic form leads to the conductor in the superconducting state, which will no longer be affected by the electromagnetic force (this has been confirmed).

In addition, there is a direct relationship between the microscopic morphology and the AC gravitational field. Some microscopic morphology is more perfect, and the topology is more difficult, which means that the requirement (temperature) for activating the superconducting state is higher.

On the contrary, it is a high temperature superconducting material.

After hearing what Wang Hao said, Lin Bohan suddenly felt a little incomprehensible. "In the concept of topology, there is no concept of size. The infinitely extending two-dimensional cylindrical plane should be discussed in terms of geometry."

"Maybe it can also be understood as 'directed topology'?"

"If we study the original form of topology, we can create a 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 discussed it together.

...

According to the actual needs of research, it is indeed a very interesting job to define a new geometric space.

Geometry is not fixed.

The geometric theorems in primary and secondary school textbooks are just the foundation of the foundation. When we really enter the field of geometry, all conventional definitions and axioms become a common basic definition.

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 (point of 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 the total length is limited.

These definitions clearly defy common sense.

But Riemannian geometry is the mathematical basis of general relativity. At the same time, Riemannian geometry is also an important tool in mathematics. It is not only the basis of differential geometry, but also applied to differential equations, variational methods, and complex variable function theory.

What Lin Bohan and Wang Hao are doing now is trying to define a new geometric space so that it can meet the research needs.

For this reason, Wang Hao also established a task of "research on the microscopic morphology inside the conductor"——

【Task 1】

【Research Project Name: Research on Microscopic Morphology Inside Conductors (Difficulty: S). 】

[Inspiration value: 17. 】

...

Time seems to be the least of the things when it comes to a really interesting study.

Soon another two weeks passed.

This time node has become very important, because the International Congress of Mathematicians held in Austria is about to start.

Domestic academic circles are very concerned about this International Congress of Mathematicians.

A lot of people focus on the awards.

Although it is said that Wang Hao will definitely win the Fields Medal, there is no 100% certainty whether it will be awarded to Wang Hao, and Wang Hao's award is obviously of great significance.

One is that he will become the first domestic scholar to win the Fields Medal.

Two, he will become the youngest winner in Fields history.

Both of the above points are very important.

Xihai University was not worried about winning the award, especially the few people who knew the details, including Luan Haiping, Chen Qinghua, and other senior leaders of the school, they knew very well that Wang Hao would definitely win the award.

because……

Medals and certificates have been sent to Xihai University in advance.

The Fields Award 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 medal and certificate, and on the other hand, they wanted to have a simple award ceremony through video communication.

There are two staff members who came here.

One is Kim Hee-nian and the other is Brown Brodbeck.

After they came, they were warmly received by Xihai University. Even if they were just ordinary staff members, they would definitely be treated differently if they came here to present the Fields medals.

Brown-Brodbeck is more focused on work. After he came, he wanted to talk to Wang Hao about receiving the award.

"Where is Dr. Wang?"

"We're going to talk about the award process, or the communication process."

Jin Xinian explained, "Our job is not only to deliver medals, but also to ensure smooth communication. We wait for Dr. Wang to finish his report before leaving."

The school sent someone to find Wang Hao.

Wang Hao is doing research with Lin Bohan, and it can be said that he is humble when he stays at home. Their research is so crazy that they ignore time.

When he heard that the Mathematics Association sent someone to present the medals, he just waved his hands and said, "I paid attention to the time, isn't it tomorrow?"

The opening ceremony of the International Congress of Mathematicians is indeed going on tomorrow.

Brown-Brodbeck and Jin Xinian couldn't see Wang Hao, so they could only stay in the hotel for one night in depression, but they still couldn't see Wang Hao the next morning.

Not only were they anxious, even the people in the school were also anxious.

This is the Fields Medal Ceremony.

Even if he has already won the award, the awarding process is also very important, because Wang Hao is likely to win the award, and there will be a live broadcast by the media at the scene, 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, rushed to the restaurant quickly, almost dragging him to the government affairs building.

An office in the government 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 time to pay attention. It doesn't start until after nine o'clock. I plan to go to the office..."

"It's already half past eight!" Zhou Qingyuan hurriedly 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, and we are all worried about you. What if we miss it?"

"Will not……"

Wang Hao said weakly, he was still thinking about geometry problems in his mind, and he really didn't pay much attention to the award, anyway, he must have won the award, so just come over when the time comes, and just show his face on the camera.

What follows is an anxious wait.

The others looked even 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 is the award ceremony, and the first award to be awarded is the Fields Medal. It can be said that it reached a climax all at once.

On the screen next to the office, the real-time situation of the scene was displayed, and the host shouted, "The list of Fields winners will be announced next."

"First of all, Lorcisco..."

"He was developing stochastic conformal maps, the geometry of Brownian motion in two dimensions..."

"Herder Bhargava..."

"Alex..."

The host said three names in a row, and the mathematicians whose names were called stepped onto the stage respectively, and took away their own medals and certificates, and also said a brief exclamation by the way.

Then the host announced the last name, "I think everyone has already known it in advance."

"The last winner, Wang Hao!"

"Dr. Wang Hao has made outstanding contributions in the field of number theory and partial differential equations."

"He proved the century-old Goldbach conjecture, and he solved the NS equation problem directly related to the application."

"At the same time, he also completed research on Kakutani's conjecture, the division of infinite columns, and Monge's Ampere equation..."

"This year's Fields Medal should of course be awarded to him."

There was loud applause from the scene.

The host continued, "Dr. Wang Hao didn't come to the scene, but we can contact him by video call."

The big screen switched to the office of the Xihai University Administration Building.

Wang Hao was dressed in casual clothes, with a background of symbols behind him. Standing in front of the camera, he waved and said hello, "Hi everyone."

Brown Brodbeck and Jin Xinian appeared together, handed over the medal and certificate respectively, and also helped Wang Hao hang the medal around his neck.

When Wang Hao faced the camera again, he also knew what he should say. He thought for a while and said calmly, "Now, I feel very excited."

"The Fields Medal is the highest award in the international mathematics community, and it is very meaningful."

"Everyone knew I was going to win, but I didn't even know it myself."

"I went to have breakfast this morning and I was dragged here to accept the award. What a surprise!"

"Thanks to the International Mathematical Society, thanks to Xihai University, and thanks to all of you..."

After he finished speaking, he turned his head to look at the others, and the meaning in his eyes was, "Is this okay?"

A group of people fell silent.

The eyes and expressions they looked at seemed to be describing a few big words, "Can you be more fake?"

(seeking a monthly ticket)
