Chapter 378: I still have to learn

Unlike the previous Wenhai self-driving trip, this time Li Zheng was driving a lot more stable both in his mentality and in his driving skills.
Because he knew that no one's car could hit him on the entire highway.
While driving, he pointed to the trunk.
"There is also GPS positioning. If we roll over in the mountains, the rescue team can easily find it."
"In addition, there are a week's worth of food reserves, emergency medical kits, knives to control the edges and small water purification devices.
"Theoretically, we only need to purify the water discharged from our body to live a long time."
"I have also read the edible guide for insects and wild mushrooms. It's steady.
"Um..." Lin Yujing became more and more terrified when she heard it, "Should we go to Wushan or cross the Taklimakan..."
"Be prepared or not." Li Zheng smiled. "This is probably the consciousness of the head of the family."
Lin Yujing looked back and saw all kinds of emergency supplies in large and small packages. Although it was too much, she shook her head and smiled: "However, you are really careful. I thought you would bring a car of papers..."
Li Zheng's eyes glared, and he almost stepped on the brakes: "Say it earlier, now it's too late to turn around and print the papers and go to the study room."
"Oh..." Lin Yujing sighed helplessly, "Sure enough, I'm still trying to force myself... Actually, I can do it. I can make papers and go camping."
"???" Li Zheng's expression tightened, realizing that things are not simple.
Based on the principle of "women speak against hearing", she should have a clear intention.
If you speculate like this, there is no doubt -
This is a trap!
"When you say camping, you must camp." Li Zheng said sharply, "I like camping."
"You really don't have to force yourself." Lin Yu rested quietly on the car window, lit the glass casually, and sighed.
Li Zheng also felt cold.
Under what circumstances is the mood so depressed?
Is this also a trap?
After weighing it up, Li Zheng said tentatively: "If you feel uncomfortable... why don't we just find a place to relax and relax?"
"It's okay."
All right?
Woman, there is no okay.
Their existence is something.
Li Zheng thought for a while and decided to take a gamble.
Because of the guarantee of vehicle safety, for the first time in his life, he chose to hold the steering wheel with one hand and silently put his right hand on Lin Yujing.
Lin Yujing shrank with a groan, but didn't shoot him away either.
Li Zheng was stable, and he smiled casually, "If you have any troubles, just talk about it. Is the lesson too simple or the teacher is too slow?"
"It's a professional thing..." Lin Yujing sighed again, "Astronomy... I feel like there is nothing to do..."
"Aren't there many big astronomy projects?"
"We have to wait, and we have to wait a long time. Even if the telescope and astronomical satellite are built, we have to wait a long time to accumulate data, and then find out the worthy part of them." Lin Yujing stared at the sky, "Although I hate going abroad , But sometimes, I really want to see what Voyager 1 sends back..."
After thinking a little bit, Li Zheng gradually returned to the state of holding the steering wheel with both hands.
"Can I understand this way--"
"In view of the one or two generation gap between our country's astronomical telescopes and Europe and the United States, the astronomical data you will have access to in the future will be extremely limited, and even those that European and American astronomers have studied half a century ago."
"As for the new generation of large-scale telescopes, although our project has been launched, some things can be researched in the distance, and there may be 10 years away."
"Yeah." Lin Yujing nodded, "For a long time, the observation data I have access to are not as attractive as those published by NASA and the European Observatory."
"So you haven't even eaten with me recently, so you've been worrying about this?"
"No, I have been studying."
This seems very perfunctory.
But Li Zheng has a way to know if she is really perfunctory.
Learn the wheel of eyes-卍jie!
【Lin Yujing】
【Academic Ability: 2268】
In contrast, Li Zheng himself experienced crazy learning in the second half of the week, and his academic ability was only 4327.
This progress has been exaggerated.
"Um..." Li Zheng trembles a little while driving, "After Huang Er, I am a little uncomfortable with your study intensity."
"Then do you know why?" Lin Yujing turned to look at Li Zheng with a smirk.
"Ha, I knew it." Li Zheng raised his eyebrows excitedly, "You finally like learning too."
"Um..." Lin Yujing rubbed her forehead with difficulty.
The reason is of course not that she likes to learn...
But Li Zheng, who she likes, likes to study.
She just didn't want to be too far behind, and went from head to head to gradually become coaxed by Li Zheng.
that……
Wouldn't it be the second Zhang Xiaoke!
Lin Yujing's originally relatively low mood was aroused by this again, and she turned angrily out of the window: "I warn you, never coax me."
"Huh? Why did you say this after a good conversation?"
"Just don't coax!" Lin Yujing turned her head and stared.
"Well, don't rush, don't be angry, don't be angry."
"You are just coaxing." Lin Yujing instantly regained the feeling of screaming and punching, "Dogs want to coax."
"Where and where are all this..." Li Zheng laughed nonchalantly, "Well, well, I'm going the other way...what you love, I learn from me, it has nothing to do with you."
"Well, that's right." Lin Yujing nodded in satisfaction.
Li Zheng has never seen such a requirement, and the number of layers has exceeded the limit of his emotional intelligence.
However, it seems that he has a high status.
so be it.
Let's talk and study more happily.
Li Zheng turned to ask: "Speaking of which I have recently focused on studying condensed matter, have you learned it?"
"???" Lin Yujing said in shock, "I just happened to be learning this recently."
Sure enough, it's still fun to study!
To your mother's feelings, we will only talk about studying in the future.
Li Zheng just got interested: "How far have you learned?"
"Ordinary graduate student status."
Li Zheng laughed at the words: "Aha, you can't do that. I am at least an excellent graduate student."
"I am self-effacing."
"There is no self-humility in learning, you just don't have confidence."
"Turn around! Take the papers!"
"Don't worry." Li Zheng smiled, "Take it, I'll go out overnight, can I not bring the paper?"
"Just know!"
"I'll talk about it later," Li Zheng asked again, "After learning, I have a new understanding of cutting-edge science."
"!!!" Lin Yujing seemed to have been poked, and instantly gestured with radiance.
"That's it. Before going to university, I always thought that the more you get to the forefront, as the majors are subdivided, the distances in various fields will get farther.
"Who knew it was the opposite."
"The frontier science part is exactly the intersection of various disciplines."
"The previously coarsely divided physics, chemistry, and biology have been recombined in every field."
"For example, the electron microscope you just did is a device for biological research invented by physicists, and it turns out that chemistry is also very useful."
"Condensed matter also has a lot of chemistry and materials science content."
"It feels like the elites in various fields, when they have nowhere to go, they suddenly start to visit each other."
"100% of the same feeling." Li Zheng also exhilarated, "I thought condensed matter was such a difficult thing, but when I learned it, I was inexplicably smooth, but now I think about it, it is a hodgepodge of disciplines."
In fact, the specific content of condensed matter is not as tall as its name itself.
Approximately equivalent to "solid physics + materials science + physical chemistry + chemical physics".
Essentially, it is still studying the structure and properties of matter.
The application is mainly focused on materials.
Maybe it was just to distinguish from those few seemingly earthy majors that I took such a tall, handsome and physical name.
Objectively speaking, 70% of physics professionals in the world are engaged in condensed matter.
There is no other reason. This has application value, and it is easy to get funds and produce results.
At the same time, this seemingly "dirty" major eventually became the ultimate destination of most "physical geniuses who aim to unify field theory."
Li Zheng and Lin Yujing are relatively simpler. Although theoretical physics is the Holy Grail, they are not too obsessed with it. Moreover, it is useless to obsess over such things.
Before they knew it, they all became "big net players."
The atmosphere on this road also transitioned from "emotional running-in" to "learning and discussion" in an instant.
Speaking of condensed matter, this quickly involves the most popular "topological material" aspect.
If ordinary people can barely understand the concept of condensed matter, it is almost impossible to understand topology. It is a difficult concept of advanced mathematics.
But as Li Zheng who insists on the "Feynman Learning Method", he has very high demands on himself.
For him, the ultimate criterion for understanding a concept is
Can explain to Liu Xin within 50 words.
From general relativity to calculus in Russian elementary schools.
Of course, based on Liu Xin's knowledge structure, this type of explanation always ignores some rigor and uses some grounded metaphors.
For example, topological materials, if they are translated to Liu Xin, can only be crudely "resistant materials".
The so-called resistant material means that no matter how you twist it, tear it, freeze it, scald it and electric shock it, its properties can be as perfect as before without a slight change.
In theory, even you can arrange its atoms into a one-dimensional straight line, but its essence can still be the same as the original.
It can be said to be a macroscopic display with a strong quantum flavor.
The front is like this. It was already a multi-person movement of materials science, physics, and chemistry. However, when it comes to topological materials, even quantum physics is actively involved.
...
In the parking lot at the foot of Wushan Mountain, when Li Zheng stopped the car, he was already sweating.
It’s not that I’m tired of driving, but it’s a good chat.
Sure enough, learning is the ultimate enjoyment.
It is fun to study with the people in the academy, but the rhythm is still too old, how can it collide with Jingjing.
Similarly, Lin Yujing has re-experienced the suffocation of sweaty shirts in high school.
The reason why the university is dull and boring...
Turns out it was just because the scum smell was not enough!
"Sure enough... we made a mistake." Li Zheng turned off the engine and nodded vigorously, "Go to death with boyfriend and girlfriend... Study, I really want to study with you."
"Hmm!" Lin Yujing was so bad that she was aphasia, "Don't stop, it's time to say that graphene is superconducting."
Hearing the word graphene, Li Zheng frowned.
"Oh ha!" Lin Yujing raised her brows, "Yuan Yuan is second?"
"To shut up……"
"Hahahaha!" Lin Yujing covered her mouth and laughed wildly, "Yuan Yuan II, Yuan Yuan's successor, purely made in China Yuan Yuan..."
"Is it fun?"
"Extra fun."
no way……
Speaking of physics, condensed matter, topological materials, superconducting topological materials, graphene.
You can't get around Yuan Yuan, a young genius.
Compared with Li Zheng, he is more rooted and popular. He was born in the Junior Class of the University of Science and Technology and became famous in Berkeley, California.
When Li Zheng turned out to be born, the media would naturally take him to Yuan Yuan, who appeared on Nature at the age of 22.
Of course, Li Zheng himself respects him very much, but he is very vomiting when he is called XX second all day long.
If not, he would rather be called Li Yi II.
No loss, and faintly showing a domineering.
The two talked about graphene while they were backpacking for mountain climbing.
This is undoubtedly another serious blow to the mood for the family of three who were traveling neatly and happily next to each other.
"No one understands graphene better than me."
"You are still excited by saying that you are Yuan Yuan's second place. Then tell me what is the one-dimensional structure of graphene?
"nanotube."
"Zero dimension."
"Taylene."
"Three-dimensional?"
"Three-dimensional...what is the three-dimensionality of graphene?"
"Graphite, scum!"
"Damn... I lost on such a boring question... Then can you name three ways to make graphene?"
"Chemical vapor deposition, mechanical stripping, molecular assembly, this kind of problem is too stupid, slag. Now you can fill in the hexagonal honeycomb structure of graphene. Set the distance between two carbon atoms as a, immediately The mind calculated its two-dimensional inverted vector."
"Wait, I have to stop and stare at this... well a/2(3, +-√3). Now that you have raised your level to this point, we might as well discuss the Fermi energy level..."
Originally and He Meimei's family, watching these two people quickly pass by.
Unconsciously, it rolled up.
"You look at people, you are about the same age as you... What did you learn in school?"
"Language... Language..."
"Recite a "Song of Everlasting Regret"."
"Huh? Is there this?"
This way, like flying clouds and sweeping the sun, others can't see the two of them at all. They only hear nouns such as "tight-binding model" and "I-V curve" that will kill you, and they are left behind.
When they reached the top, the two had a clear condensed matter.
Although there was no intention to take a photo, he still reached the commanding height of the mountain with an elevation stone monument.
Thoroughly, there is a desire to shout.
Li Zheng didn't care about it, so he faced the mountains and started panting.
"Don't don't!" Lin Yujing looked around nervously, "Don't shout strange words here..."
"Eh, it's a very serious word." Li Zheng sucked Mouzu, and yelled at the mountains with a demon-like nature
"Lin Yujing, I want to study the subject with you!!! Wonderful or not!!!"
After all, he is a strong physique, this roar is full of breath, and the echo is loud.
It made everyone around me stupid.
What is this horse riding?
Suicidal confession of extremely straight male academic bully?
This should have been shameful, but Lin Yujing was inexplicably ignited.
Under Li Zheng's push, he started to face the mountains and squeezed his eyes hard to respond.
"Wonderful! Condensed state is wonderful!!"
Everyone around sat down.
This is... a pair of Wenquxing, fallen into demons?
