Chapter 127 Is Chen Yuanguang qualified?

Chen Yuanguang can understand why everyone is so enthusiastic about room-temperature superconducting technology.

Whether you understand it or not, you should pay attention to it. A live broadcast room of a person burning a stove on Bilibili can have tens of thousands of people watching online, and Damao’s live broadcast on Twitter also has tens of thousands of people watching.

The whole world is experiencing the same cold and heat, and everyone hopes that what the Koreans say about LK99 is real.

The reality is too cruel. Technology has stagnated, the benefits brought by the traditional division of labor among countries around the world have disappeared, and geopolitical conflicts have intensified. If we look at a longer period of time, we will find that the intensity of hot geopolitical events is gradually increasing every year.

People find it difficult to see hope in the real world. Everyone misses the golden age around the millennium. Although classes and the gap between the rich and the poor still exist, there is more room for class mobility.

Compared with the present, it seems so beautiful.

It is difficult to return to the golden age in reality, and everyone’s intuitive feeling of the golden age is the rapid development of the Internet. Internet technology and the golden age are highly tied together. In a sense, the productivity explosion brought about by Internet-related technologies is an important reason for the formation of the golden age.

When LK99 appeared, people realized that if room-temperature superconductivity is true, then technology can solve most problems.

The cake is not big enough to be divided, but room-temperature superconductivity can be achieved. First, the cake can be exponentially larger, and second, there is an expectation. The technological breakthrough can bring the next golden age to the world.

At least thirty years.

It is precisely because of this beautiful fantasy that people’s discussion and attention to LK99 are unprecedentedly high, and everyone hopes that it is true.

LK99's original paper was reproduced at the speed of light by Chinese scientific research institutions.

On the Chinese Internet, even if this thing is developed by Koreans, everyone hopes it is true.

Because once room-temperature superconductivity is achieved, all of humanity will benefit.

To put it more bluntly, the large-scale application of room-temperature superconductivity requires industrial production capacity, and China is the only country in the world that can produce such a large amount of capacity.

A large number of netizens on Zhihu have clearly analyzed the interests involved. One netizen joked: "Even if this allows Koreans to monopolize the Nobel Prize in Physics for the next ten years, I still hope that room-temperature superconductivity is true."

There are also a lot of people following Chen Yuanguang’s Weibo hoping that he can talk about this matter.

As China's most well-known scholar in materials science, netizens want to hear Chen Yuanguang's opinions.

"Light God, what do you think of LK99?"

"It is said that the Meissner effect has been observed. If room-temperature superconductivity is true, what impact will it have on society?"

The Meissner effect refers to a physical phenomenon in which a material repels a magnetic field when it transitions from a normal state to a superconducting state.

The LK99 material that has gone viral on the Internet and is suspended above a magnet is what we are talking about: the Meissner effect.

"God of Light, are people's previous directions for achieving room-temperature superconductivity wrong? Is flying bricks with great force the right way?"

From ChatGPT at the beginning of the year to room-temperature superconductivity in the middle of the year, plus SpaceX's Falcon 9, netizens feel that these explosive technological breakthroughs are a bit like flying bricks.

Like rocket launches, we used to think that it depended on rocket design, fuel, etc. SpaceX launched one after another, with the frequency of explosions as high as fireworks, and finally made the Falcon 9, which clearly tells you that it depends on horsepower, and if the horsepower is strong enough, it can fly.

If one engine doesn't have enough horsepower, then use two. If two aren't enough, then use four. In short, it's always possible to get a few more engines bundled together.

Previously, people thought that the core of artificial intelligence lies in models and algorithms. ChatGPT tells us that models don’t matter, what matters is data and computing power.

Combining the success of these two, everyone would think that room-temperature superconductivity is also based on the same principle, that it requires great force to make miracles happen.

The Koreans used furnaces to produce usable room-temperature superconductors.

After Chen Yuanguang reviewed the recent chaos regarding room-temperature superconductivity, he knew what he should do:

"Room-temperature superconductivity will undoubtedly be one of the important keys to the new world. If it is truly realized, new batteries, global power grids and quantum computers will become possible, and the research and development of controlled nuclear fusion will also be accelerated.

There is no doubt that it is very important. Whether LK99 is real or not, I think it is not a superconductor itself. The superconductivity it shows experimentally comes from the structural transformation of Cu2S. "

Chen Yuanguang rarely posted a long Weibo post in response, which increased the already high level of discussion even more.

"Chen Yuanguang publicly responds to LK99" quickly topped the Weibo hot search list.

A group of media called the securities management department of Guangjia Technology, hoping to interview Chen Yuanguang.

The media are creatures that survive by chasing hot topics. As there are no sensitive factors that prevent people from talking about these hottest global topics, they are naturally crazy about them.

“How do you evaluate Chen Yuanguang’s claim that LK99 is not a superconductor and that its superconductivity comes from the structure of Cu2S?”

After the two hot topics on Zhihu intersected, the questions also quickly sparked discussion among netizens.

If you want to dash everyone's hopes, don't blame the Zhihu netizens for being rude:

"Lexation, what does Chen Yuanguang, a perovskite researcher, know about superconductors?

First, he has not done any experiments, and second, he is not working in this field. Why does he suddenly come out and say that LK99 is not a room-temperature superconductor?
I know that because there have been too many room-temperature superconductivity scams in the past, people have doubts about this, including the recent case in March when the room-temperature superconductivity proposed by the University of Rochester was proven to be a scam.

That achievement was rated as one of the top ten discoveries in the world in 2020, but was falsified this year. This time it was Gao Li who claimed that he had figured out room-temperature superconductivity.

Goryeo's academic credibility is even lower, so it is normal for people to have doubts.

However, it is obviously unreasonable for Chen Yuanguang, as a public figure, to say this. He leads the public in this direction without any evidence, which is disrespectful to the researchers who have been adhering to LK99 for a long time.

Why are people paying so much attention to this and feel it is highly credible? Because there are theories, phenomena and historical accumulation.

It did not emerge suddenly. Looking back now, Professor C began to study room-temperature superconductivity many years ago and proposed the one-dimensional superconductivity theory:
Some linear materials may have superconductivity because the electrons in linear materials move in a straight line and do not run around in other directions, making it easier to achieve superconductivity.

This theory is logically self-consistent, and other physicists have also put forward similar views, including the superconducting effect we have observed in some polymer materials.

Of course, this theory is a relatively niche theory and not many people agree with it, but historically it is common for niche theories to make a comeback. For example, graphene and liquid crystal were both theoretically believed to be impossible to exist, but they were both synthesized and finally new models were found theoretically to explain them.

Therefore, Professor C discovered that the most powerful way to prove that the theory he supported was correct was to synthesize a linear-structured superconducting material according to this theory, and then all doubts would be silenced.

In 1999, two students of Professor C made LK99, which showed anti-magnetism. We can see in the video that it can levitate on the magnet, which is the Meissner effect. This is because when a superconductor enters a magnetic field, an induced current will be generated inside, and the induced current will generate a magnetic field. The repulsion between like charges will cause the superconductor to levitate.

And because it is a superconductor with no resistance, this induced current will exist forever, which means that the superconductor will remain suspended like this forever.

LK99 exhibits incomplete anti-magnetism, which means that one side of the LK99 material will stick to the magnet, while the other side will always float.

At the same time, from the observation point of view, LK99 has a resistivity jump at room temperature, which means that the resistivity of LK99 will suddenly decrease at a certain temperature.

This is the specific property that LK99 exhibits when it is synthesized.

The properties exhibited by LK99 are consistent with the one-dimensional superconductivity theory proposed by Professor C. It is divided into two parts, one is an insulator with no conductivity, and the other is a one-dimensional superconducting structure.

LK99 cannot be completely suspended on the magnet because the one-dimensional superconducting structure inside LK99 provides suspension force for the material, but because there are still a lot of insulating structures inside, it can only be partially suspended. Moreover, since the distribution of the one-dimensional superconducting structure is uneven, part of LK99 must be attached to the magnet.

The reason for the change in resistivity is also easy to explain. The superconducting phase in the material reaches the transition temperature, so the resistance is greatly reduced. However, due to the large amount of insulating structure in the material, the overall resistance of the material is still very high.

LK actually does not want to publish the research results so quickly because it is not rigorous enough at present, which is also the main reason for the controversy.

The third party published the paper without permission, and many laboratories have reproduced the experiment, but no conclusion has been reached yet. It is undoubtedly inappropriate for Chen Yuanguang to directly make a judgment on the case on Weibo. "

"I object to the answer with the highest number of likes under my real name. Guang Shen, as a PhD in materials science from MIT, is not qualified. But you amateur scientists are qualified, right?
Isn't perovskite also a compound? There is no essential difference between it and LK99's alchemy? Guang Shen can refine perovskite to the best in the world. What's wrong with his opinion on LK99?
As for not respecting the R&D personnel of LK99, do we have to support LK99 to show respect? And Guangshen also expressed his own views, without any personal attacks or definite conclusions. He only said what he thought, not what it must be.

I think LK99 supporters are crazy. If you don’t support LK99, you will be attacked.”

"Lexarnacle, I don't think Guang Shen didn't know about LK99, or that he didn't do experiments. He can clearly say that Cu2S is the effect, which means he has done experiments and comparative analysis, so he made this judgment.

The models and methods that Guangshen left behind in computational chemistry and biocomputing are still mainstream research methods. If he had stayed in academia, he would have been considered a top expert. Therefore, I personally still believe in Guangshen's judgment. His achievements in materials science are beyond doubt."

The point on which LK99's supporters on Zhihu oppose Chen Yuanguang's views is that he is not a superconductor researcher and is not qualified to make a judgment.

Chen Yuanguang's supporters cite his academic achievements as an example.

From Zhihu to Weibo to Douyin and Bilibili, the argument continues.

The degree of support is gradually increasing, with the lowest proportion of people supporting Chen Yuanguang on Zhihu and the highest proportion on Bilibili.

The popularity was too tempting, so the official staff of B station who was responsible for the operation of the up master found Li Xiyin and said, "Xiyin, is it possible to invite Guangshen to be interviewed again?
Let him talk about LK99.”

Li Xiyin looked worried. "I can't invite him. Guang Shen is studying LK99 and doesn't have time. I haven't seen him for a long time."

Li Xiyin actually didn't ask, not even to Lin Jia, because she felt that the topic of lk99 could not support a long interview.

Moreover, she didn't want to waste her favors on this, as it created another layer of distance between her and Chen Yuanguang.

The staff of station b also want to try: "Can we?"

Li Xiyin didn't wait for her to finish: "No!"

The popularity of room-temperature superconductivity is so high that the share price of a stock called Western Superconducting in the American Stock Exchange has soared by 30% and has continued to rise for several days. The so-called superconducting concept stocks in the A-share market have also followed suit.

Guangjia Technology is counted as a superconducting concept stock because it holds 20% of Xiaomi Auto's shares. Room-temperature superconductivity will allow electric vehicles to completely replace oil vehicles, which is a major benefit for new energy vehicles.

After Chen Yuanguang posted on Weibo, Western Superconducting began to plummet and returned to where it was supposed to be. At the same time, superconducting concept stocks in the A-share market also began to plummet.

Guangjia Aerospace actually rose, and no one knew why. The experts in the stock forum analyzed:
"Because of the insight and judgment shown by Guangshen in scientific research, investors are more optimistic about the future of Guangjia Technology."

In short, if you want to find a reason, you can always find it.

A month later, various experiments were completed one after another, and it became a consensus in the academic community that the superconductivity of LK99 came from Cu2S.

Of course, there are still supporters of LK99 who insist that LK99 is a superconductor and has superconductivity, but most of the academic community's attention is no longer on this.

On Zhihu, the previous question began to be dug up like crazy:

"clown?"

"? Question the God of Light?"

"The God of Light knew a month ago that the abnormality in LK99's resistance was caused by Cu2S. These institutions have to conduct experiments to find out. What is the scientific research intuition of top geniuses?"

"Are you still being tough?"

Chen Yuanguang's supporters patrolled the opposing answers on Zhihu as if they had won a battle.

In the Guangjia Aerospace laboratory, a thin sheet of material is suspended on a magnet. Unlike the one-sided suspension of LK99, this time the entire material is suspended on the magnet, which is very obvious.

The resistivity in the computer next to it has also dropped to a level much lower than that of LK99. The curve graph of the sudden drop is as attractive as the Qingming Shanghe Tu.

The researchers from Guangjia Aerospace who participated in this project stared at this thing with shining eyes:
“We did it.”

"This is not a superconducting phase. What is a superconducting phase?"

"The boss is amazing. This is a Nobel Prize-level achievement."

"Don't even mention the Nobel Prize. Winning a Nobel Prize for this achievement is an honor for the Nobel Prize, not an honor for the God of Light."

Inside Guangjia Aerospace, there are people called Boss Chen Yuanguang and others called God of Light.

Chen Yuanguang was not very proud of it because it was not his research but copied.

The biggest difficulty in making this thing is to reproduce it using the technology of modern time and space. Many equipment in the future time and space are not available in modern time and space.
