Chapter 380 (1/2)
For those who are interested in scientific research, learning is the only thing that can't be stopped.
When he stops studying and consumes the knowledge of the past, he will be dead.
Or worse than death.
He will unconsciously become a superior exploiter, and use his reputation, status and contacts to become the resource allocator that young people have to rely on.
Fortunately, most scholars did not stop.
Li Zheng wants to surpass the past.
With the further study of condensed matter and superconductivity, Yuan Yuan has finally become a learning object that he can't get around.
Different from those academic achievements which are too complex to be understood by ordinary people, Yuan Yuan did only one seemingly trivial thing in his amazing paper -
stacking two graphene films together.
Then rotate 1.1 degrees.
Then, like the Buddha.
This piece of graphene becomes a superconductor.
To confirm this, an environment of 1.7k (- 271.45 ℃) is needed.
Although this kind of environment is strict, it still does not hinder the importance of this discovery, as well as the magic.
It's just this magical, 1.1 degree rotation that completely changes the nature of a lump of matter.
Therefore, this angle is also called magic angle.
Once magic appears, it often means that this is something that human beings can't explain.
But that doesn't prevent humans from trying to debunk it.
Scientists are just a group of people who expose magic.
Since then, scholars have carried out in-depth observation of magic angle graphene system by using scanning tunneling microscope.
Modern science can't explain this with abstract principles, but the tools are so sophisticated that they can observe the movement of each electron in it.
It is found that when there are too many or too few electrons, magic angle graphene is like a normal metal, in which the electrons are in independent state.
However, when the number of electrons is at the critical point of superconductivity, strong interaction and entanglement occur suddenly.
Just like the sentence ”to have light”, superconductivity happened at this moment.
With the emergence of the terms ”strong interaction” and ”entanglement”, the theoretical research on this phenomenon has reached the edge of science.
There is no doubt that this is the subject of quantum physics.
In this step, Li Zheng gradually realized a funny fact in modern scientific research.
Although the principle of science has stopped for a long time, there is no reason for scientific experiments to stop.
We can even twist two layers of two-dimensional graphene by 1.1 degrees. It can be seen that experimental physics has been crazy for many years.
It's a great discovery, of course, but as long as the fundamentals don't explain it, it's just a discovery.
These layers of ”why” questions will eventually be handed over to quantum physics to solve without exception.
But quantum physics itself does not seem to have completed its own definition.
”Biophysics” in the classroom before class, Li Zhengshu breath, closed the book.
”This time, it's really a high challenge.”
”It's better to cast a net and gamble.” Lin Qijing dragged and rolled the catalogue of papers on the computer screen and said, ”every substance that seems to be superconducting will be torn and twisted in various ways, and then it will be electrified in a low temperature environment. Once superconductivity is triggered, it will be stable in this lifetime...”
”Superconductivity?” One of the students in the back looked up and said, ”do you play that game, too? Can't ice and thunder trigger superconductivity? ”
The two turned around and looked at the classmate incomprehensibly.
Although I don't know what he is talking about, it seems reasonable that low temperature + electrification = superconductivity.
Under the two people's serious examination, the classmate quickly retracted.
”Excuse me I should have made a mistake Can't you stop playing... ”
At this time, Mo Nian in the front row also turned around and asked with restraint.
”I've been listening. Can I make an opinion?”
”Brother Mo, please.” Li Zheng certainly nodded.
Mo Nian opened his arms and said, ”in fact, it's not only physics, but also biology. It's all under the micro conditions like a headless fly that makes all kinds of mischievous collisions, hoping to discover some extraordinary function in one of them. So is chemistry in general. I don't like it, but I don't know what else to do in the future. ”
”Even if there is a little inspiration, who is willing to take the route of exhaustive method?” Lin Qijing closed the computer, lifeless hands holding his cheek, ”now it seems that if we want to do superconductivity, we are just looking for a big probability direction, looking for a reliable material to start hitting by mistake.”
Mo Nian said with a smile: ”if you want to be more open, I don't know what else I can do anyway. It's better to enter the laboratory and have a blind talk than to have a class here.””Shhh...” Li Zheng quickly raised his hand, ”Miss Cui is looking at this side...”
Mo Nian took a look at Cui Shenzhi, who was wronged to steal a glance. He quickly turned back and bowed his head: ”offended, offended...”
Mo Nian turns back, and Lin yuejing lies on the table and sighs: ”otherwise, change the direction. Half of the physical world is walking in the field of head smashing, just want to stay away from it...”
”Cough...” Li Zheng coughed and said with a smile, ”is the first reaction to escape?”
Many people have resisted instinct since childhood No matter how delicious the fish is, I don't want to wait in line. ”
”All right.” Li Zheng said, ”this time, I also think it's meaningless to try and gamble blindly. There are too many people doing this. It is inevitable that there are a large number of secret repetitive research, which is a waste of research resources. Don't waste resources Even if I look at their existing papers, I can't see them, and there are dozens of them growing every week... ”
”Well...” Lin qiojing suddenly got up and stood up. After a few serious pauses, he suddenly turned his head and asked, ”do you remember how scientific laws came into being? The most basic three steps. ”
”1. Discover phenomena; 2. Summarize and put forward hypotheses; 3. Practice verification.”
”Which part of it is the smartest person to do?” Lin asked with all his eyes
”Summarizing the rules, of course.” Li Zheng eyes a stare, a clap table, ”wonderful ah!”
”So.” ”Thousands of papers about phenomena are in front of us. Why not try to do the smartest part?”
”There is no doubt that a lot of smart people are already doing it...” Li Zheng rubbed his chin and thought quickly, ”but if we do I think of a lot of chemical ideas And Mathematics My algorithm strength has not been used for a long time All in all Wonderful
”And this idea doesn't have to grab laboratory resources, otherwise it will be very troublesome.”
Li Zheng immediately nodded: ”the disadvantage is that it is very difficult to achieve results, and it is likely to waste a year's efforts.”
”So what?” Lin Yue Jing licked his lips and said with a smile, ”anyway, I am also a person who gives up casually ~”
”wait a minute, why do you suddenly become small
”Go, go, go!” ”Do you want to do it?” Lin asked
”Why not Li Zheng immediately raised the table and said, ”the edge of science, step up!”
Mo Nian in the front row, in an instant, a strong man with banana king style turned back and said with a smile: ”I heard the call.”
”Brother Mo, calm down This is pure theoretical research There's no room for you. ”
”Ah...” Mo Nian suddenly withered down and slowly turned back, ”yes This time it should be the world of two of you In a word, just call me whenever you need to... ”
Then, Li Zheng and Lin Yue Jing, holding hands, slipped out of the classroom at the moment before the bell rang.
Physics class should be relieved, but think about it carefully
This restless leave, this impulsive punishment.
Where will they go when they leave in such a hurry? What are you going to do?
Damn it In the end, the lesson still doesn't smell good!
The worst is Cui Shenzhi.
Clearly Worked hard to prepare for the week's
Make up your mind, this time you'll catch your heart
Don't you give me a chance?
The only exception is someone who doesn't seem to exist.
