Chapter 387: Learn! determine!

This night is destined to sleepless.
When researchers are full of inspiration, no one can stop them from burning their lives.
If something is destined to be made by God, then this night is the moment when God's hand comes.
In their intense discussion, Li Zheng did not even deliberately guide, just follow the branches of the theory to explore, and the research route naturally emerged from the mist.
Among the three scientific cards that have been launched before, [High Temperature Superconductivity] belongs to the experimental field, and you can buy with academic funds for inspiration at any time.
In the field of superconductivity, the meaning of high temperature is somewhat different from that of daily life. Even -50°C can be regarded as high temperature.
Even two or three years ago, if superconductivity can be achieved at a temperature of "-50°C", it would be enough to make headlines in "Nature".
Of course, the pursuit of temperature is only one direction in superconductivity research.
For example, Yuan Yuan’s graphene superconductivity was achieved extremely close to absolute zero (-271.45°C) without any breakthrough in temperature, but this does not prevent him from helping people approach the truth.
The pursuit of "high temperature" is more like a race to break the world record.
According to classical theory and experimental results over the years, for the same substance, to achieve higher temperature superconductivity, it will inevitably rely on a higher pressure environment.
Therefore, in the field of "high temperature superconductivity", scientific research competition has gradually evolved into an industrial competition. Whoever can create a higher pressure environment has the capital to win.
This also explains why superconducting temperature records are refreshed several times a year.
As of this evening, the temperature record was temporarily -23.15°C, which was achieved by a German team using lanthanum cyanide compounds.
Of course, this still requires one million times the atmospheric pressure, which is approximately equivalent to the pressure of the earth's core.
This temperature is very encouraging for laymen, but condensed matter scholars are very calm about it, and they have no doubt that this record will be broken in a short period of time, just find something reliable at two million atmospheres.
Just like challenging the world record, this route itself is full of Olympic flavors, and its honorary significance has far exceeded its practical value. After all, the cost of building a superconducting cable with a pressure of 1 million atmospheres has long exceeded that of -200℃. The latter can be realized a long time ago, and it will even be installed in Xujiahui area of ​​Shanghai Stock Exchange.
From Li Zheng’s point of view, even if he buys this card and has a full set of experimental parameters, I am afraid he will not be able to have a laboratory that can provide geocentric pressure. There are only three or five in the world, and it is not his turn. .
What's more, this card only requires 500 academic qualifications, which is the same level as the previous cryo-EM.
How come this mission is going to be level 1500!
Relatively speaking, the [Magic Horn Model] this technology card fully meets Li Zheng's expectations.
Although there are three existing theories that seem to be unrelated to superconductivity to be learned, as long as they can be learned, there is no problem.
As for the description of the card, it is even better.
【Magic Horn Model】
[Discover the preconditions of superconductivity theory. 】
[Humans have already discovered the existence of magic horns, and can even calculate and infer magic horns to a certain extent, but still cannot fully understand it. 】
[Exploring two-dimensional quantum tunneling and finding electronic speed bumps will be the key to understanding it. 】
[Extending it further to three dimensions will be the true starting point of superconductivity theory. 】
【After you complete the pre-content learning, you can spend 2000 points to get inspiration. 】
【Pre-Content:】
【Quantum Chromodynamics】
【Tight Binding Model】
【Strong Association System】
At the end, this is no longer a wonderful question.
Li Zheng's mind is full of two words.
Study, study, study, quietly, study, study...
Although something is coming in, I can't wait to be hungry and want to learn.
As for these three pre-contents, the [tight-binding model] is the core tool of the Portuguese papers and must be learned. [Strong correlation system] has been introduced in the conversation, so Li Zheng only needs...
"Hmm..." Li Zheng nodded with his chin, "I feel that our knowledge of quantum chromodynamics is still slightly insufficient..."
"According to what you said, everything is a little insufficient." Lin Yujing only habitually scolded because she knew Li Zheng too much, "You just want to learn more!"
"Wait..." Jie Qifen raised his hand. After thinking about it carefully, he was surprised, "You kid is smart enough!", "Li Zheng mentioned the norm theory of strong interaction. It can indeed provide a very basic perspective for the next research."
Hearing this, Li Zheng quickly pressed Lin Yujing, who was awkward, waved his hand and said, "That's for sure. After we have supplemented the three parts of quantum chromodynamics, tight-binding model, and strong correlation system, we will focus on collecting all relevant magic. Kok’s theoretical essay. In my spare time, I turned this Portuguese essay into a purely mathematical problem and handed it to Guijian Fengpinpin."
"Okay, that's it." Xie Qi breathed a sigh of relief, got up and picked up the table, "I have found an exact direction, but I don't know what time it is. If it's still early, I will accompany you to have a supper..."
After he finished speaking, he raised his hand and took a look: "Why is it past six o'clock..."
"This..." Li Zheng swallowed and spit out and looked out the window, "This is obviously morning, old explanation."
"!!!" Jie Qifen was startled, and hurriedly stuffed things into his bag and ran out, "It's over, my mother is going to scold me! Tomorrow...oh no, see you tonight."
Seeing Xie Qifen rushing away, Li Zheng and Lin Yujing also smiled at each other.
"It turns out to be an aunt Boer..." Lin Yujing squeaked and carried her schoolbag.
"It shouldn't be so superficial." Li Zheng embraced Lin Yujing towards the door of the classroom, "Imagine that his mother should be his only support these years."
"In that case, he is the only thing my mother can rely on..." Lin Yujing suddenly felt a little sad, leaning in Li Zheng's arms and muttered, "I don't even dare to think about it... If one day my grandfather is gone... ...Then I..."
Li Zheng's eyes widened and his hands clenched: "Then you are mine alone!"
"???"
"Just kidding, my grandfather will live a hundred years old, a thousand-year-old turtle." Li Zheng laughed and turned off the light and locked the door, taking the opportunity to raise his eyebrows, "This guy is shouting not to get married. But I found out that he kept the photos of Teacher Tang."
"Teacher Tang?"
"Tang Zhifei, I have introduced it, like Fu Xuefeng and Tao Feifei."
"Is this...is this appropriate?" Lin Yujing scratched her head vigorously, thinking about it, "One must bear the smell of tobacco and alcohol... the other must bear... Then what, isn't this home going to be a chemical laboratory? Can the old lady bear it?"
"No, no, there is no way to react to tobacco, alcohol and foot odor. It is more likely that one of the parties has achieved a repressive victory." Li Zheng said, suddenly remembering something, "He seems to have not smoked for a long time."
"Yes, I remember you said he was smoking violently in class... Actually it doesn't seem to be?"
"Always so clear, it seems that I haven't drunk alcohol." Li Zheng nodded and said, "In this way, he is already working hard, and he only needs to resist the taste of Teacher Tang."
"Hey, when did it become a taste dispute?" Lin Yujing waved her hand vigorously, holding her cheek in a very understanding way, "Lao Jie has been refusing to meet, because he must feel that he is quiet. Don't go to Teacher Tang, this time, it just helps him build his confidence."
"Confidence? He doesn't lack confidence, right."
"Oh!" Lin Yujing zhenzheng raised her hand, "You are handsome, you have a good family, and you can also publish papers. You can't realize the psychological contradictions of normal people at all. Solving their disputes is definitely academically confident. Yes, but he is only a scientist in classrooms and laboratories. Once he leaves the campus and returns to society, he is no more than an unmarried lecturer in his 40s. No matter how bad his feet are, Mr. Tang is still more than 20 years old. Year-old beauty."
"Can you say that again."
"Teacher Tang is a foot..."
"Not here, the opening sentence."
"At the beginning? Even if you are a handsome family..." Lin Yujing realized what was going on in the middle of speaking, and thumped Li Zheng, "All boring!"
"Haha." Li Zheng laughed, "Let him decide on the old solution. We are only responsible for making the ‘scientist’ part well. Once this is done, everything will be fine naturally."
"I didn't expect that much." Lin Yujing smiled indifferently, "Although I really think that something can be done, it is a theoretical direction after all. What can I prove even if I write an article? Let alone us, even if It was published by someone of Zhong Ping's level. I am afraid that it will take many years for this kind of theoretical article to be recognized...If that is the case, even if we really create a terrific theory, the old explanation will be fifty or sixty. Years old... sigh... he couldn't speak earlier..."
"Whether he will marry a wife or not, why are you so anxious..."
"Distressed! Such a good teacher should have been successful. Chu Youhua's assets are hundreds of millions. The children's tuition fees are more than Lao Jie's salary."
"Is this so rich?"
"It seems that they are the shareholders of two listed companies in Quantum Science. I also heard people say."
"This is really uncomfortable."
Li Zheng rubbed his chin and responded.
"Looking back when there is a chance, you have to re-allocate..."
...
Time flies, learning like a shuttle.
Although the weather is getting colder, thinking and inspiration are steaming and cracking like magma.
Until one weekend in mid-December, Xie Qifen had to take his mother to the hospital to fetch medicine, and had to take a day off. Li Zheng and Lin Yujing did not die, but drove to an old community 5 kilometers away from the school.
According to the house address, the two climbed all the way to the fifth floor and knocked on a quaint big green door, uncertainly.
It was a thin man who opened the door. Although he met for the first time, he was terribly enthusiastic.
"Fengfeng's classmate, right? Quick, quick, please come in!"
Forbidden to change slippers, the man just pulled the two in, and kept muttering: "The first time a classmate came to him...what do you want to eat at noon? I will prepare it for you, and you can go out to eat. "
"Alright..." At this moment, when I saw the wind came out from the back room, he grabbed Li Zheng and Lin Yujing and pulled in, "You leave me alone, we just stay alone..."
Li Zheng was stagnant, not because of Gui Jianfeng’s lovely velvet pajamas, but because—
[Let's see the wind]
【Academic Ability: 2899】
Is this TM still a person? ?
It seemed to be around 1000 before.
What happened to Grandpa in the past few months?
Changed him a 3080 graphics card?
On the other side, even though the old man was left out, he still smiled and said, "Then I will go to your grandma's place. I will put the lunch money on the table and eat whatever you want."
After that, he took the bill and changed his shoes and left with a smile.
Gui Jianfeng breathed a sigh of relief when he heard the door closing, entered the room and motioned for the two to sit casually.
It's not that Li Zheng and Lin Yujing don't want to sit...
Mainly there is no place to sit.
Except for the aisle and the humanoid area on the bed, there are draft papers filled with calculations on all sides, and standing here is already very laborious.
Lin Yujing also swallowed and spit: "Fengfeng looks clean, the habits are so bad..."
After seeing the news, I hurriedly raised my hand and swept a few laps, and he just cleared the space for two buttocks on the bed, and scratched his head and smiled: "At first, my dad would clean up, but later I found that every time I cleaned up for a day. It’s going to happen again, just do it, sometimes I think of things I calculated before, and it’s easy to get them."
Li Zheng scanned the stacked layers of draft paper and said, "It's all messed up, can you still find what you need?"
"It's okay. Anything you have thrown will have an impression, such as the S matrix theory." After Gui Jianfeng said, his head immediately turned to the bed, then leaned over and twitched on the ground, took a look and smiled and flashed the draft paper to Li Zheng said, "So I like to stay at home~"
Li Zheng looked at the paper and shook his head blankly: "I don't care, you are fooling around. Anyway, I don't know what the S matrix is..."
"Haha, it's up to you." Gui Jianfeng brushed the paper on the chair and sat on it. "You didn't look for me during this period. It happened that my grandfather Jing had posted a lot of articles and topics for me, and I was always there. I didn't stop. Sister Jing said that he had read all the papers of mainstream mathematics journals in the past 40 years and selected them for me. I didn't believe it at the beginning, but now I am convinced.
"My grandfather really watched it." Lin Yujing nodded vigorously, "I remember the publication day, every time he cooks a meal in the morning on the publication day, he ignores me. , I dare not call him on the publication day."
"Ha, really." Gui Jianfeng said with a smile, "With this level of learning, only Li Zheng can fight with him, right?"
"Our father and I are not fighting." Li Zheng nodded his head in a focused manner, "It's a boil."
"You're fighting an eagle here."
"That's interesting." Li Zheng laughed, took out seven or eight sheets of paper and handed them to Gui Jianfeng, "This is a paper that inspired us before. I transformed it into a mathematical form. You Help me see, there are a few theoretical solutions."
"I know physics too. Don't do that." Gui Jianfeng shook his head and smiled and took the paper. After a glance, he immediately moved the chair back to the table, "I took back what I said just now. I have never seen this kind of physics. Wait a minute, give me 10 minutes."
Li Zheng panicked: "No, you can see this within a week. I may not be able to finish using the computer in 10 minutes."
However, Gui Jianfeng ignored him and started to pull the draft paper for himself.
Seeing this, Li Zheng had to smile with Lin Yujing and sat back on the bed.
Waiting like this is not a problem. After waiting for two minutes is boring, Li Zheng raised his hand and squeezed Lin Yujing.
"Why are you pinching me?" Lin Yujing cursed, covering her face.
"I'm trying." Li Zheng did face a serious expression, and looked at Fenbijishu's return to the wind seriously, "How far is he able to study like this?"
"Then why are you pinching me!!"
"I am idle as well. I think it's better to make some noises, do some things, and see how stable his academic spirit is."
"Then... Then why am I not pinching you?"
"Yes, come on, pinch."
"Don't stand up, what kind of posture is this."
"You don't pinch? Then I'll pinch you."
"You start and drive!!"
During the dispute, Gui Jianfeng suddenly waved his hand and said without raising his head.
"5...no no, wait a minute, 8 solutions."
Li Zheng's figure was shocked, and he could no longer be pinched or pinched.
It is the magic angle calculation process of double-layer graphene that is handed over to Gui Jianfeng.
The paper finally gave 5 possible magic angles, which is also Gui Jianfeng’s first reaction.
But 8? Are there situations that the computer has not considered?
"What then?" Li Zheng rushed over and asked, "How did those three come out?"
"It only exists in theory. You need to use imaginary numbers. No matter how many tools you can understand, you won’t understand." Returning to Jianfeng, twisting the pen and turning over the paper, "I haven’t calculated it yet, it’s just a feeling, but I have calculated it. With so much, I feel that the correct rate is basically 100%. Give me half an hour and I will try."
"please!"
Seeing Gui Jianfeng moving with all his strength, Li Zheng returned to the bed cautiously, never daring to mess around anymore, just staring at him silently.
"Only mathematics..." Even Lin Yujing had to be worshipped, "There is no room for resistance in front of Fengfeng..."
"Since he knows how to count...for more than ten years, he does 14 hours of math every day..." Li Zheng shook his head dullly, "I can't imagine his brain structure anymore..."
"I really want to see him solve puzzles with Lao..."
"Even if the two universes are about to collide..."
