MTL - The Science Fiction World of Xueba-Chapter 377 New Generation 1 Manned Space Project

Associated Press: "The Swedish Nobel Prize Jury has just announced that Chinese scholars Pang Xuelin and Kirton Walker have jointly won this year's Nobel Prize in Chemistry."

The Times: "The youngest Nobel Prize for science in history was born, and Pang Xuelin set a new age record maintained by the late British physicist Lawrence Prague."

Agence France-Presse: "The lithium-air battery project won the Nobel Prize in Chemistry this year, and the Chinese genius has become the youngest Nobel Prize winner in history."

Sankei Shimbun News: "The son of the dragon creates another miracle, and the Nobel Prize in Chemistry ends in China."

Chosun Ilbo: "Pang Xuelin leads China's scientific and technological progress. Unfortunately, Pang is not a Korean ..."

"..."

Compared to the sour tone of foreign media, Chinese media is not blowing money.

Tencent News: "Guo Shi Wu Shuang, Academician Pang Xuelin won the second Nobel Science Prize trophy in China, and the Chinese academic community ushered in the era of Pang Xuelin."

Today's headline: "Shocked! The story I had to tell with Professor Pang Xuelin, it turned out that Professor Pang in daily life turned out to be like this ..."

Sina News: "The twenty-four-year-old Nobel Prize winner, Academician Pang Xuelin will inject new impetus into China's scientific and technological innovation."

Observer: "What else can we say besides worship? China won two Nobel Prizes in chemistry in one day. In a sense, Pang Xuelin has become an icon of our time!"

Fenghuang.com: "The pride of Chinese people in the world, Professor Pang Xuelin will surely enter the annals of history!"

"..."

Pang Xuelin doesn't have much time to watch online discussions and news.

After answering those congratulatory calls, he had to continue the Xiangshan Science Conference.

When the plan is basically approved by the congregation, in the afternoon, the participating scientists will start discussions on the technical route of the scheme listed by Pang Xuelin.

This kind of discussion is much easier than the kind of needlepoints that are coming to Maimang in the morning.

However, in most cases, it was Pang Xuelin who explained and the experts attending the meeting were listening.

After all, for such an unprecedented super project, no one except Pang Xuelin has experience.

Therefore, Pang Xuelin can only decompose the entire plan, and each project is explained to everyone.

The afternoon meeting lasted until five o'clock. When Pang Xuelin thought that he could finally rest, Zuo Yiqiu came over and told Pang Xuelin that the reporter from CCTV was here and hoped to have an exclusive interview with Pang Xuelin.

Pang Xuelin had to follow Zuo Yiqiu to the reception room of the room and saw Dong Qing, an old acquaintance who had been waiting in the reception room for a long time.

"Reporter Dong, it's you, it's been a long time."

"Academician Pang, I did not expect that after a year, we will meet again. You are already the legendary Nobel champion."

"Haha, reporter Dong joked."

"..."

When Dong Qing interviewed Pang Xuelin last year, the two were already familiar with each other, so this time, the two talked very easily.

"Professor Pang, this interview is more formal. In addition to" NEWS Hookup "in the evening, we will also release the full content of the interview in" JD Interview "later. Do you need to prepare for the questions I will ask next? ? "

Pang Xuelin smiled and shook her head: "No need, just start."

If it was left in the past, Pang Xuelin might be a little bit prepared. Now, after the transformation of genetically optimized medicaments, when it comes to agile thinking, he is no less inferior to those real geniuses, and naturally will not show cowardice in this situation .

Dong Qing winked at the cameraman on the side and smiled: "Since this is the case, let's start now, the first question."

"Professor Pang, when did you receive your news about your award? How was your mood then?"

Pang Xuelin said: "It should be around 10:30 in the morning. I was in a meeting at the time, and then Mr. Herbert Green, the chairman of the Nobel Prize Judging Committee, suddenly called. I was still a little bitter when I picked it up."

"A little shit? Are you surprised that you won?"

"It's not an accident, how to say? I didn't expect Mr. Green to call directly because I was discussing a very important topic at that time, I didn't think so much at all."

"Then what do you think of your own award? And according to the record, you have broken the record of the youngest Nobel Prize for Science held by British physicist Lawrence Prague. What do you think of this?"

Pang Xuelin said: "I was prepared for the award. After all, it has been on the Internet for so long. As for the record breaking, I have great respect for Mr. Lawrence Prague, and I am honored to break the record maintained by Mr. Prague. , I also hope that someone will continue to break my record in the future, because this represents the future of humanity. "

"Thank you Academician Pang, did you call your family after winning the award? What did you say to them?"

Pang Xuelin smiled awkwardly: "I haven't talked to my parents on the phone."

"what?"

Dong Qing's face was surprised.

Pang Xuelin laughed: "My parents sent me a WeChat, but they didn't say much. They knew that I was busy, so if I was okay, I rarely contacted me. Generally, I contacted them when I was free. People get together again. "

Dong Qing nodded with a smile and said, "What about your friends and colleagues? Have you talked to them?"

Pang Xuelin nodded: "There are a lot of this. After winning the award, I received at least more than 20 congratulatory calls. There were Tao Zhexuan, my postgraduate mentor from the other side of the ocean. Professor Schultz in Europe, Professor Faltings. Of course, more domestic colleagues, friends, and students ... Oh, by the way, Kirton Walker also called me to congratulate me, Then I also congratulated him. "

Dong Qing couldn't help laughing, "The two Nobel Prize congratulators congratulate each other, and the scene should be very interesting."

Pang Xuelin smiled and nodded.

Dong Qingdao: "Can you tell me the story of you and Mr. Kirton Walker? The outside world's interactions between you are all from Professor Kirton Walker. You never seem to talk to the media about this. topic."

Pang Xuelin smiled and said, "Courton Walker bragging for me, will I take the initiative to blow myself, will it be too high-profile?"

"Haha!"

Dong Qing raised his thumb to Pang Xuelin and said, "But we just want to hear how you tout yourself."

Pang Xuelin deliberately revealed a reluctant look on his face, and smiled, "I'll try it."

"The first time I met Professor Kirton Walker, at a cold dinner in Princeton, I gave a report in Princeton, and then unexpectedly proved that Polignac conjecture ..."

"At the first sight of Professor Kirton Walker, I thought he was a liar."

"con man?"

Dong Qing was somewhat surprised.

Pang Xuelin laughed: "Yes, that's the kind we often see on TV to promote health products. He told me at the time that he could get a lithium-air battery, and then bragged me how wonderful the future of the lithium-air battery is. In fact, my heart was rejected at that time, because I knew the plight of lithium-air batteries. It wasn't until he told me to isolate the aqueous electrolyte of lithium-air batteries by graphene. Because of this idea and I happened to agree on the lithium-air battery project. "

"Then we talked more and more speculatively, and Professor Kirton Walker proposed cooperative research to me. But considering the sensitivity of this technology and the investment in research and development, I asked Professor Kirton Walker to come to work at Jiangda University. I I was thinking about whether the other party would hesitate. After all, Princeton and Jiang University, objectively there is still a certain gap between the two universities. I did not expect that the other party agreed without hesitation. Later I learned that Professor Kirton Walker It has been blackened by the American industry, and it is not valued in Princeton ... "

"..."

The interview lasted more than an hour before it was considered over.

Due to time constraints, Dong Qingwan rejected Pang Xuelin's invitation to eat and set off directly for the city.

In the "NEWS Hookup" that night, Yang Ma rarely gave Pang Xuelin a report time of nearly ten minutes and introduced all his achievements since his appearance in the academic world.

At the end of the news, Yang Ma reported: "Professor Pang Xuelin, as a national treasure-level strategic scientist, does not stigmatize his mission, leads scientific and technological innovation, and has made outstanding contributions to the scientific and technological progress of our country and all mankind. . "

After "NEWS Hookup" ended, "JD Interview" simultaneously broadcast Dong Qing's exclusive interview with Pang Xuelin.

The playful dialogue between Pang Xuelin and Dong Qing quickly spread on the Internet, causing a lot of sensation.

"Haha, the first time I saw Professor Pang have such a lifelike aspect, I feel that Professor Pang is no different from normal young people."

"It's no different, except that people's brains are filled with gold, and my brain is with thatch."

"Don't you find that Professor Pang is getting more and more handsome? It is much more handsome than those little fresh meat in the entertainment industry. What should I do? I feel like I want to powder him."

"Well, you know, is my favorite bean in the entertainment industry comparable to those cheap and cheap goods ..."

"Let my husband go, no one is allowed to rob me ..."

"..."

Even Pang Xuelin didn't expect that he didn't know when he had an exclusive fan group on the Internet. The fighting power of these fans, even among the rice circle girls, was among the best.

In the words of one of his fans: "It's called talent, it's a face ..."

Although he basically did not post Weibo on a daily basis, in just two years from opening to the present, Pang Xuelin has exceeded 20 million followers on Weibo.

This is the actual number of fans, and those who buy fans are essentially different.

Pang Xuelin didn't pay much attention to this, and now his main energy is still at the Xiangshan Science Conference.

The Xiangshan Science Conference lasted for three days before it was concluded.

After the meeting report is released, it will be submitted to the top leadership for final decision.

Pang Xuelin originally thought that nothing would happen to him.

As a result, after the Xiangshan meeting, he was called into Dainei and participated in a higher-level meeting.

Finally, on the last day of the National Day holiday, high-level decision-making passed the project plan of the electromagnetic orbit space launch system proposed by Pang Xuelin.

The name of the plan was named China's New Generation Manned Spaceflight Project, and Pang Xuelin became the commander of the project.

It's just that the plan came out, it seemed a bit silent, not only did there not be any reports in the media, even inside, it was in the stage of absolute secrecy.

According to Pang Xuelin's plan, this project will mainly make relevant theoretical and technological breakthroughs in the short term, and then allocate related funds in batches according to the progress of technological breakthroughs.

So on the first day of the plan's launch, the first batch of 10 billion RMB of scientific research funds was directly deposited into the Qiantang laboratory.

After all these tasks were busy, Pang Xuelin set aside two days to accompany Yao Bingxia for a round of fun around Beijing, and then returned to Jiangcheng by special plane.

The first time he returned to Jiangcheng, Pang Xuelin directly called all the members of the Flying Blade Materials project team and re-examined the upgrade plan of the Flying Blade Materials, and then asked the project team to dock with Xinkai Materials Co., Ltd. to realize the Flying Blade Materials as soon as possible Mass production.

Only then did Pang Xuelin begin to have time to focus his research on normal temperature superconductivity.

In fact, in Pang Xuelin's reward from the dark forest world, there is no related technology of room temperature superconductivity.

In the dark forest world, the reason why Wade and their team created a super-electromagnetic catapult orbit more than 20 kilometers long was piled up at no cost.

The niobium-titanium alloy and liquid helium used to maintain the superconducting effect alone cost trillions of dollars.

In the real world, Pang Xuelin cannot do this at all.

Therefore, he must find another way to find the superconductor physics mechanism with universal significance.

The so-called superconductor refers to a conductor with zero resistance at a certain temperature.

The discovery of superconductors is inseparable from low-temperature research. In the 18th century, due to the limitations of low-temperature technology, it was believed that there were "permanent gases" that could not be liquefied, such as hydrogen and helium.

In 1898, British physicist Dewar produced liquid hydrogen.

In 1908, Professor Camerin Ones of the Leiden Cryogenic Laboratory at Leiden University in the Netherlands successfully liquefied the last "permanent gas", helium, and obtained 1.15-4.25 by reducing the vapor pressure of liquid helium. K's low temperature.

A breakthrough in low-temperature research has laid the foundation for the discovery of superconductors.

In the physics world in the late nineteenth and early twentieth centuries, there were different opinions about the change in the resistance of metals near absolute zero.

One view is that the resistance of pure metals should decrease with decreasing temperature and disappear at absolute zero.

Another view, represented by William Thomson (Baron Kelvin), believes that as the temperature decreases, the resistance of a metal reaches an infinitesimal value due to the condensing of electrons onto metal atoms after reaching a minimum value.

In February 1911, Kamalin Onis, who mastered liquid helium and cryogenic technology, found that the resistance of platinum remained constant below 4.3K, instead of increasing after passing a minimum value. Therefore, Kamalin Onis believed that the resistance of pure platinum should disappear at the temperature of liquid helium.

To test this conjecture, Kamalin Onis chose mercury, which was easier to purify, as the experimental subject.

First, Kamalin Onis cooled the mercury to minus 40 ° C to freeze the mercury into a linear shape; then, the temperature was lowered to about 4.2K using liquid helium, and a voltage was applied across the mercury line; At K, the resistance of mercury suddenly disappears, showing a superconducting state.

Later, after research by many scientists, it was discovered that superconductors have three basic characteristics: complete electrical conductivity, complete diamagnetism, and quantization of flux.

The so-called full conductivity, also known as zero resistance effect, refers to the phenomenon that the resistance suddenly disappears when the temperature drops below a certain temperature.

Full conductivity is suitable for direct current. Superconductors will have AC loss under the condition of alternating current or magnetic field, and the higher the frequency, the greater the loss.

AC loss is an important problem to be solved in the practical application of superconductors. In the macro, AC loss is caused by the difference between the induced electric field and the induced current density generated inside the superconducting material. Caused by stagnation.

AC loss is an important parameter to characterize the performance of superconducting materials. If AC loss can be reduced, it can reduce the cooling cost of superconducting devices and improve the stability of operation.

Second, completely antimagnetic, also known as Meissner effect, "antimagnetic" refers to the phenomenon that the magnetic field cannot pass through the superconductor when the magnetic field strength is below a critical value, and the internal magnetic field of the superconductor is zero. "Complete" refers to reducing the temperature The order of reaching the superconducting state and applying the magnetic field can be reversed.

The reason for complete diamagnetism is that the surface of the superconductor can generate a lossless diamagnetic superconducting current. The magnetic field generated by this current cancels the magnetic field inside the superconductor.

Superconductors have a well-known characteristic of zero resistance, but superconductors are not equivalent to ideal conductors.

From the electromagnetic theory, the following conclusions can be derived: if the ideal conductor is cooled to a low temperature and then placed in a magnetic field, the internal magnetic field of the ideal conductor is zero; but if the ideal conductor is first placed in a magnetic field ~ www.novelbuddy.com ~ After cooling to low temperature, the magnetic field inside the ideal conductor is not zero.

For a superconductor, the two operations of reducing the temperature to achieve a superconducting state and applying a magnetic field, regardless of the order, the internal magnetic field of the superconductor is always zero, which is the core of complete diamagnetism and the key that distinguishes a superconductor from an ideal conductor.

Third, the flux quantization effect, also known as the Josephson effect, refers to the phenomenon that when an insulating layer between two superconductors is as thin as an atom, an electron pair can pass through the insulating layer to generate a tunneling current, that is, in the superconductor-insulator- Superconductor structures can generate superconducting currents.

Josephson effect is divided into DC Josephson effect and AC Josephson effect.

The DC Josephson effect means that an electron pair can form a superconducting current through an insulating layer.

The AC Josephson effect means that when the applied DC voltage reaches a certain level, in addition to the DC superconducting current, there is an AC current. The superconductor is placed in a magnetic field, and the magnetic field penetrates into the insulation layer. The size of the magnetic field changes regularly.
