Wang Yinan was a little surprised that Professor Tao was invited to attend the press conference, and it was not surprising that Mr. Yau could attend, because Hong Kong Island is very close to the imperial capital, and Mr. Yau has always had a reputation in the industry for promoting backward people.

On the morning of the press conference, Wang Yinan made a special trip to the airport to greet Professor Tao and her wife and assistant Laura.

"Our president entrusted me to come", Professor Tao's answer was very simple,

"Just to let me say that the door of UCLA is always open for you", Wang Yinan suddenly realized, no wonder UCLA has been booming in recent years, just looking at the courage of people to poach people, it is not comparable to second-rate universities in China.

Wang Yinan formally thanked the president of UCLA for his hospitality, but Wang Yinan and Li Wenjing, who had just been promoted to distinguished professors of Imperial Capital University, estimated that they would have to spend at least a while at Imperial Capital University.

According to the original plan, the press conference was originally going to be held in the auditorium of the Department of Physics, but just after noon, reporters from all walks of life and self-media people who followed the trend had already filled the auditorium of the Department of Physics.

Therefore, the Imperial Capital University hurriedly coordinated to cancel an open class originally scheduled for the university's large lecture hall, and the press conference was rescheduled to the large lecture hall, and the police were temporarily invited to maintain order. At half past one in the afternoon, with the joint arrival of Mr. Qiu and Professor Tao, reporters gathered around like crazy, "May I ask Mr. Qiu, are Wang Yinan and Professor Li Wenjing your new students?"

"May I ask Professor Tao, you have rarely participated in public events recently, why did you participate in this press conference of Imperial Capital University this time?"

"There is news that you will be a visiting professor at Imperial Capital University, is the news true?" ，

"May I ask Mr. Qiu, it is said that you have a conflict with Professor Tao and rarely appear in the same public place, is this true?"

Ignoring the reporters' harassment, Wang Yinan and Li Wenjing accompanied the two Fields Medal winners to the VIP room at the edge of the conference hall.

The room has gathered many domestic physics leaders, including but not limited to the presidents of Imperial Capital University and Mizuki University, Director Zhao of the Institute of Cryogenics of the Chinese Academy of Sciences, and Professor Cui of Ji University, who once observed superconductivity in high-pressure hydrogen sulfide.

After a brief greeting and introduction, the time for the press conference is about to come, under the leadership of the staff of Imperial Capital University, the guests from all walks of life in the VIP room were brought to the simple rostrum to take a seat, today's protagonists are undoubtedly Wang Yinan and Li Wenjing, so they were arranged to sit in the middle of the rostrum, in the world of science, there are not so many seniority, what should be yours is yours, Wang Yinan and Li Wenjing did not give in.

Rong and the company's relatives and friends occupied the most front position in the audience, Zhang Qi, Qian Zhonghua, and of course, Deng Ruoyan and Zhou Hui arrived early, and they waited for the historic moment together with many reporters.

didn't invite another host to distract him, how could Principal Lin give up this kind of opportunity to show his face to others.

The hour hand pointed to two o'clock, and President Lin motioned for the audience to be quiet, "Today, all the experts, leaders, and friends from the media, in their busy schedules, I would like to express my heartfelt thanks and great honor to be able to attend the press conference held by the Joint Laboratory of Low Temperature Physics of Imperial Capital University-Ronghe Company."

"I am President Lin XX of Imperial Capital University, and I would like to introduce you to all the guests who participated in this press conference."

"Mr. Yau, Director of the Institute of Mathematics, Hong Kong Island Chinese University, Fields Medal Winner",

"UCAL Professor, Fields Medal Winner Mr. Tao Zhexuan",

"Academician of the Chinese Academy of Sciences, Academician of the Third World Academy of Sciences, Professor Zhao YY",

。。。

Balabala introduced more than a dozen names, of course, all of them are names that are qualified to be on the rostrum, and the department heads of ordinary universities are not qualified to be on the rostrum.

After the introduction, President Lin didn't talk nonsense, "Next, I would like to invite Professor Wang Yinan and Professor Li Wenjing of Imperial Capital University to introduce their research results to you."

Wang Yinan took the microphone,

"It has been exactly 100 years since Onnes discovered that the resistance of mercury disappears at low temperatures",

"Even if it is more than 50 years since the BCS theory was proposed, it is still a luxury to have a complete theory that can predict the phenomenon of superconductivity until today."

"Because everyone knows that the BCS theory does not apply to the copper oxides that have recently made great breakthroughs."

While Wang Yinan was talking, on the other side of the ocean, in the office of Princeton in the early morning, Cheng Qian, Thomas and the main members of the team gathered around and watched the live broadcast of Huaguo TV, "I heard the theory of superconductivity phenomena correctly", Thomas asked, Cheng Qian was responsible for translating Wang Yinan's speech into English.

"You heard it right, that's what Wang Yinan said", Cheng Qian's face was cloudy, and he couldn't see his emotions.

In Europa, Chinese graduate students who spent a lot of money from the physics department of the University of Berlin translated Wang Yinan's speech into German and English sentence by sentence, and when he heard the sentence "the theory of predicting superconductivity phenomena", like Thomas, Arthur repeatedly confirmed that Wang Yinan did not say so.

"Here I would like to mention an old man who pioneered the idea when he was at the University of Paris in France that Cooper pairs are nothing more than approximations of some superelectron pairs."

"As long as we master the theory of the formation of such superelectron pairs, we can establish a completely new theory of superconductivity, and it is even possible to predict the composition of superconducting materials."

"This old man's name is Li Shiyao, Li Wenjing's father and my teacher",

"After returning to China, Mr. Li continued to refine his theory, and first discovered the existence of superconductivity in copper oxides, of course, due to the scum of some scientific researchers, this honor was not attributed to his old man", Wang Yinan was silent for a while,

"History may be tortuous, maybe sometimes, dark clouds will block our eyes, but, one day, everyone will get a fair evaluation of history, true can not be false, false, not true."

"Fortunately, Mr. Li did not wait long in the sky, his students, and his daughter, followed the path he pioneered, and to this day, we have come far, far and far, to places that no one has ever been."

"We have been able to theoretically predict the composition and structure of superconductors, calculate their critical temperatures, and prepare them, and finally confirm our predictions with experiments!" ，

The information of this sentence is too big, the knowledgeable people in the audience, as well as all the experts who watched the live broadcast on Blue Star, including Arthur, Cheng Qian and Thomas, all gasped, and the scientists who had just won the world record in the Sun Country opened their eyes even more, and there were words in their mouths, "Bragging, he must be bragging, how can anyone do it to this extent."

Wang Yinan didn't let the audience wait too long, "Next, let's witness this great moment", he and Li Wenjing stood up and walked to the front of the rostrum.

"Please ask Professor Zhao of Imperial Capital University, as well as Director She of the Institute of Cryogenics of the Chinese Academy of Sciences, to help us take a hand", please these two, one is to let these two show their faces, and the other is to dispel some possible suspicions, if it is fake, please invite these two to make a show, don't do it? . .

All the cameras were aimed at the simple experimental table in front of the rostrum, Wang Yinan took out a coil, and the golden insulating paint concealed the color of the superconducting material itself, "This is a coil made of superconducting materials prepared according to our theoretical predictions."

The glasses of the melon-eating masses who watched the live broadcast fell to the ground again, such a large coil is actually superconducting materials? Could it be that these grandsons actually achieved mass production? But today's shock was enough, and Cheng Qian felt that he could withstand it.

Take out a piece of permanent magnet, Wang Yinan put it into the bottom of the container, "This is a piece of permanent magnet, please Professor Zhao demonstrate", Professor Zhao took out a coin, "snap", a little closer to the coin and firmly adsorbed on the permanent magnet.

Connect the two ends of the coil to the positive and negative poles of the DC power supply, and then place the coil on a metal bracket above the permanent magnet, Wang Yinan motioned to Director She to turn on the switch, "Okay, this is a simple energized coil, you see, nothing has happened now."

"As you know, an important characteristic of superconductors is that they are completely diamagnetic, and magnetic field lines cannot penetrate superconductors", Wang Yinan motioned to Li Wenjing to take out the thermos pot from under the table, opened the lid of the pot, and a wisp of mist came out, "Remind everyone, this is not liquid nitrogen", Wang Yinan said lightly.

He didn't care if he said this, and the people who ate melons were not calm at all, "What", Thomas shouted, "That's right, he said this is not liquid nitrogen", Cheng Qian seemed to have been mentally prepared, Arthur drew a cross on his chest, "Almighty Lord, it seems that the pagans in the East are actually going to take away your glory", and in the Sun Country, several scientists who are not very determined have begun to fantasize about the tragic situation of seppuku in their minds.

"This is a dry ice methanol bath, which I personally configured, and the cooling temperature is between minus 60 and minus 70 degrees Celsius," adds She, director of the Institute of Cryogenics of the Academy of Sciences.

There was a buzz in the conference hall, the previous record of the Sun Country was minus 132 degrees Celsius, which raised the critical temperature by 70 degrees Celsius, and the cost reduction and expansion of the application range from the liquid nitrogen temperature zone to the dry ice temperature zone are even more immeasurable.

Wang Yinan took the microphone away and whispered to Li Wenjing, "You come to complete the last step, on behalf of your father, this is his moment of glory."

Li Wenjing nodded heavily, and while Wang Yinan said loudly, "Let's witness the new era", he poured the dry ice methanol bath in the thermos pot into the container.

The transparent bath drowned the permanent magnets, the metal bracket, and the tiny coil in the billowing mist.

The cameras of the TV station were all focused on the small container on the test table.

At this moment, the entire Blue Star held its breath.
