Learning Demon Cultivation System

Chapter 382 Magic Angle

For those who are interested in scientific research, learning is the only thing that cannot be stopped.

He is dead when he stops learning and spends his past knowledge to get by.

In other words, it is scarier than death.

He will unconsciously become a high-ranking exploiter, using his prestige, status and connections to become a resource allocator that young people have to rely on.

Fortunately, most scholars did not stop.

Li Zheng wanted to surpass him even more.

With the in-depth study of condensed matter and superconductivity, Yuan Yuan finally became a learning object that he could not avoid.

Unlike those academic achievements that are too complicated for ordinary people to understand, Yuan Yuan only did one seemingly insignificant thing in his amazing thesis——

Stack two graphene films on top of each other.

Then rotate 1.1°.

Then, like the consecration of the Buddha.

This sheet of graphene becomes a superconductor.

In order to confirm this, an environment of 1.7K (-271.45°C) is also needed.

Although the environmental requirements are relatively strict, it still does not hinder the importance and magic of this discovery.

It is so magical, the rotation of 1.1° has completely changed the nature of a lump of matter.

Therefore, this angle is also called Magic-angle, "magic angle".

Once Magic appears, it often means that this is something that humans cannot explain.

But that doesn't stop humans from trying to debunk it.

Scientists, aren't they just a group of people who just expose magic?

Since then, scholars have conducted in-depth observations of the magic-angle graphene system using scanning tunneling microscopes.

Although modern science is still unable to explain this matter with abstract principles, scientific tools have been sophisticated enough to observe the movement of each electron in it.

The study found that when there are too many or too few electrons, the magic-angle graphene is like a normal metal, and the electrons in it are in a state independent of each other.

However, when the number of electrons is at the critical point where superconductivity occurs, strong interactions and entanglement suddenly occur between electrons.

Just like the phrase "let there be light", superconductivity occurred at this moment.

With the emergence of terms such as "strong interaction" and "entanglement", the theoretical research on this phenomenon has reached the edge of science.

There is no doubt that this is already a matter of quantum physics.

Going deep to this point, Li Zheng also gradually realized a funny fact in modern scientific research.

Although scientific principles have been stopped for a long time, scientific experiments have no reason to stop.

Even twisting two layers of two-dimensional graphene by 1.1° can be done, which shows that experimental physics has been insane for many years.

This is of course a great discovery, but as long as it cannot be explained in basic principles, then it is only a discovery.

These layers of "why" questions will eventually be handed over to quantum physics to answer without exception.

But quantum physics itself does not seem to have finished defining itself.

In the classroom before the class of "Biophysics", Li Zheng breathed a sigh of relief and closed the book.

"This time, it's a really difficult challenge."

"Let's say it's a gamble." Lin Yujing dragged and scrolled the catalog of papers on the computer screen, "Every substance that seems to be superconducting will be torn and twisted in various ways, and then placed in a low-temperature environment Once the superconductivity is triggered, there will be a feeling of stability in this life..."

"Superconductivity?" A classmate from behind poked his head over, "Are you guys playing that game too? Isn't ice + thunder triggering superconductivity?"

The two turned their heads 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 serious scrutiny of the two, the classmate quickly shrank back.

"Excuse me... I must have made a mistake... Is it okay to stop playing..."

At this time, Mo Nian in the front row also turned around and asked restrainedly.

"I've been listening, can I express my opinion?"

"Brother Mo please." Li Zheng nodded of course.

Mo Nian spread his arms at this point: "Actually, not only physics, but also biology. They all make various mistakes like headless chickens under microscopic conditions, and hope that one of them will find something great. The same is true for chemistry in general. I don’t like it very much, but I don’t know what else to do in the future.”

"Even if there is still a little bit of inspiration, who is willing to take the route of brute force?" Lin Yujing closed the computer, resting her chin in her hands lifelessly, "It seems that if we want to make superconductors, it is nothing more than Find a direction with a high probability, find a reliable substance and start hitting by mistake."

Mo Nian said with a smile: "I want to be more open, anyway, I don't know what else to do. Being able to go into the laboratory and mess around is better than taking classes here."

"Hush..." Li Zheng quickly raised his hand, "Teacher Cui is looking over here..."

Mo Nian glanced at Cui Shenzhi, who was sneaking aggrieved glances here, and quickly turned around and bowed his head: "Offended, offended..."

Mo Nian turned back, and Lin Yujing lay down on the table and sighed softly: "Otherwise, change the direction, half of the physical world is walking in the field of bumping heads, just want to avoid it..."

"Cough..." Li Zheng coughed dryly and laughed, "Is the first reaction to escape again?"

"Since I was a child, I have instinctively resisted crowded places... No matter how delicious the grilled fish is, I don't want to wait in line."

"Okay." Li Zheng spread his hands, "This time I also think it's meaningless to try and gamble, and there are too many people doing this, and it is inevitable that there will be a lot of secret and repetitive research, which is a waste of research resources. Not to mention wasting resources... Even if I read their existing papers, I can hardly read them, and they are growing at a rate of dozens every week..."

"Hmm..." Lin Yujing suddenly got up and stood up, then murmured earnestly for a few times, then suddenly turned her head and asked, "Do you still remember how scientific laws are produced? The three most basic steps."

"1. Discover phenomena, 2. Summarize and put forward hypotheses, 3. Practice verification."

Lin Yujing asked with bright eyes, "Which part of it will the smartest person do?"

"Of course it's about summarizing the rules." Li Zheng rolled his eyes and slapped the table, "Wonderful!"

"So." Lin Yujing raised her hands, "There are thousands of papers on phenomena in front of us, why not try to be the smartest part?"

"There is no doubt that many smart people are already doing it..." Li Zheng rubbed his chin and thought quickly, "But if we do it... I think of a lot of ideas in chemistry... and mathematics... I It’s been a long time since the strength of the algorithm has come in handy... All in all, it’s... Wonderful!"

"And this idea does not need to grab laboratory resources, otherwise it will be very troublesome."

Li Zheng nodded immediately: "The disadvantage is that it is difficult to produce results, and it is very likely that a year's effort will be wasted."

"So what?" Lin Yujing licked her lips and smiled, "Anyway, I'm also a person who just gives up~"

"Wait, why are you so cute all of a sudden?"

"Let's go, let's go!" Lin Yujing only asked, "Do you want to do it?"

"Is there any reason not to do it?" Li Zheng immediately stood up from the table, "The science is at the edge, let's go!"

Mo Nian in the front row suddenly turned around like a banana gentleman, with a smile on his face: "I heard the call."

"Brother Mo, calm down...this time is purely theoretical research...There is no room for you to develop."

"Ah..." Mo Nian shrank in an instant, and slowly turned around, "Yeah... this time it should be the world of the two of you... Anyway, just call me if you need anything..."

Then, Li Zheng and Lin Yujing held hands and slipped out of the classroom just before the bell rang.

The physics class should have breathed a sigh of relief, but think about it carefully...

This restless departure, this impulsive punishment.

Where would they go if they left so impatiently?What will you do?

Damn... this class still doesn't taste good in the end!

The worst was Cui Shenzhi.

Obviously... I worked hard to prepare for a week...

Make up your mind, this time I will try my best to grab your hearts...

Don't give me a chance?

The only exception is a person who does not seem to exist.

Yang Jun wiped his glasses, then put them on firmly.

"Oh, I can finally listen to the class in a down-to-earth manner."

……

In fact, the students' guesses are not unreasonable.

Li Zheng and Lin Yujing did go to a dark place hand in hand.

That is the basement of Yingpei Academy.

Since last weekend, under the arrangement of Niu Gang, this activity room has become an activity room dedicated to the science side.

In addition to the regular multimedia functions, this place is also full of various mechanical devices made by Tu Yikou. In fact, when Tu Yikou skipped class and couldn't sleep at night, he would often stay here alone and piece together. Let's realize the dream of building Gundam.

Lin Yujing was dumbfounded as soon as she came in: "Why does this seem to have a CNC machine tool? Are you going to build cannons?"

"Well, Tu Yikou told me that he was assembling men's toys."

"It's such a powerful toy...but the electricity here...wait what is that...transformer or generator?"

"Don't worry about it." Li Zheng pulled Lin Yujing over, "Before Ke Qing and Mo Ming come..."

"Hmm??? Don't be so sudden..."

10 minute later.

When Chang Keqing and Lin Moming came in, they only saw Lin Yujing lying on the table.

Li Zheng, on the other hand, just wiped his lips lightly: "Come on, sit down."

Chang Keqing's face tensed, as if he smelled a sour smell, which was worse than the engine oil that Tu Yikou got here.

Should have turned around and left.

Can……

Li Zheng's study is really great.

Sudden emergency call, that must be an exciting subject...

Scumbag!

That's what scumbags are like... except for scumbags...

There are advantages and charms all over the body.

As long as you don't want to be boyfriend and girlfriend, you are simply the most worthwhile person to make friends with.

Unlike Chang Keqing's psychological struggle, Lin Moming didn't have any extra thoughts, but ran to Lin Yujing's side with tight legs: "Sister, are you feeling well?"

"Comfortable..." Lin Yujing answered blankly, then suddenly got up with a red face, "No, no, no... uncomfortable..."

"Wow..." Lin Moming looked at her closely, becoming more and more confused, "Look carefully, sister, you are so beautiful..."

"No... not pretty..." Lin Yujing blushed and turned her head, "You can sit too."

"Can I sit next to you?"

"casual……"

"Can I sit on your lap?"

"..."

"Haha, just kidding, I'm not a child." Lin Moming pulled out the chair as he spoke, and sat on it with a jump. It was very good.

Chang Keqing sat opposite very sadly.

Not only is Li Zheng a scumbag, Lin Moming is also a scumbag...

I had to sleep with my sister the night before, and I posted it as soon as I saw a cuter one.

Sure enough, I still love to bury my heart alone.

Here, Li Zheng picked up the water bottle to replenish some water before he proposed the idea of ​​this project.

"Condensed matter is the biggest research hotspot in physics now."

"Among them, the research on superconductivity is the hot spot among the hot spots."
