This Monday is very unusual for Cui Shenzhi.

After a few weeks of school, Li Zheng and Lin Yujing rarely came to his "Biophysics" class.

No matter how kind Cui Shenzhi is, he also has a temper.

So he planned to warn the two of them during the midterm exam, although he looked down on the teacher, even if the teacher was stupid, at least the power to determine the test center was still in the hands of the teacher.

After that, for no apparent reason, he suffered an even more tragic blow.

For a lecturer, there is nothing more cruel than "the person who does not attend the class takes the first place", and there is a feeling of self-worth being denied.

But today, they came in unison.

And very honestly, didn't do anything too much in class.

Just quietly bow your head and study on your own.

Wait a minute...... On self-study?

Is it because the teacher's voice is more suitable for background sound?

If that's the case......

Cui Shenzhi thought of this, blushing and bowing his head.

That teacher is at least somewhat useful......

Presumably, if you study on your own in a biophysics classroom, it will at least be more comfortable than a silent environment.

With such a responsibility, Cui Shenzhi's lecture today is a little more gentle than before.

However, Mo Nian, who was sitting in the front row of Li Zheng, was still very uncomfortable.

The reason for the discomfort is also in terms of "self-worth".

In the past few months, he has tried to get close to Li Zheng's topic this time.

But fuck you!

What the hell?

He also learned "Advanced Mathematics", but Li Zheng and the others seem to be engaged in "Advanced 3rd Mathematics" this time, so high that they don't know where to go in mathematics.

As a pure-blooded man, this is unacceptable to Mo Nian.

He would rather be kicked out of the margins of science than tolerate being the one dragging his feet.

Go to school, learn mathematics and physics, just bow your head and study hard,

I let out a moan of pain as I learned.

"...... It's not a good thing to escort......" Mo Nian grabbed Yang Jun's thigh, "I'm lazy, I'm lazy everywhere outside of creatures......"

"Brother...... It hurts ......," Yang Jun groaned with red eyes.

Hearing such a moan, Mo Nian's heart moved, and the stone Buddha's belief was a little shaken.

But when he turned his head and saw Yang Jun's face, he instantly came back firmly.

"I'm sorry......" Mo Nian twitched his hand and said, "I've been struggling to learn high math and big things lately......"

Yang Jun rubbed his thighs and said aggrievedly: "If you are struggling, you can just tell me......"

"Your brother who doesn't know how to use a mobile phone knows a fart. Mo Nian casually unfolded the textbook, "For example, the topology here, I understand every word and every symbol, but as long as I look at more than 18 characters in a row, an infinite loop of DNA structure will appear in my mind, and then I won't know anything." ”

"This is very basic, right, wouldn't it be nice to add a few more conditional definitions to the concept of high school sets?"

"Yes, exactly. Mo Nian nodded, "I can understand every word you say, but I don't know what you're talking about." ”

"Yes, I always gave lectures to my classmates in high school, you see I use math sets to give you examples......" Yang Jun said, taking out the discarded printing paper he had taken out of the computer room and scribbling on the back.

Unlike the abstract descriptions in textbooks, Yang Jun's interpretation is extremely simple.

So much so that after reading it, Mo Nian still didn't know what topology was, but he had a kind of confidence that he could do the question.

"Yes...... It's right to put it in when you do this......"

"Hmm. Yang Jun pushed the paper to Mo Nian, nodded and said, "Actually, I don't understand many concepts, and our teachers there don't understand either, so I have to summarize some home remedies for doing questions by myself. ”

"You ...... It's very similar to artificial intelligence ......" Mo Nian shook his head, and he didn't know whether he was praising or scolding, "Although the computer doesn't know it, there is only a large string of 1s and 0s in the underlying thinking...... But it is to be able to defeat the Go champion. ”

"Where do I have the ability? Yang Jun scratched his head shyly, glanced at Li Zheng who was thinking hard behind him, and then smiled and lowered his head again, "Brother Li is still powerful, he understands the concept well, and he is ...... fast in doing problems and calculations."

"If that's ......" Mo Nian's expression gradually tightened, and he looked at his hands and said, "I'm just ...... Hands-on skills?"

"Brother Nian, don't ......be like this," Yang Jun was afraid that his leg would be pinched by him, so he hurriedly asked, "I heard the teacher say that 90% of the content of biological research is experimental? ”

"Yes for the time being. Mo Nian looked nervously, "But think about it, no matter how high the precision of human manual work is, is it higher than that of machinery? Now experimental robots have not replaced 90% of the experimenters, there is only one reason - people who are engaged in biology...... It's so fucking cheap. ”

"How do you feel, I'm talking about my second uncle who insists on cutting wheat by hand......"

"One meaning. Mo Nian hugged Yang Jun and said, "Jun, you must have come all the way here, you must not be willing to be a person who will be replaced sooner or later, you must not want to do some repetitive and boring work day after day, right?"

"This ...... In fact...... Farming is sometimes happier than studying...... Yang Jun said with a bitter face, "It's just that my hometown has a lot of fields, otherwise it may not be my turn to study...... Sometimes I envy other families who have farms...... Brother, we are different, the people in our hometown can have a job that is repeated day after day, and being able to eat and dress is the greatest happiness. ”

"Alas......" Mo Nian sighed, "I understand you, but when you really have those, you will want to get more, such as me now, there is no big problem in maintaining a research group with Professor Bing...... But Jun, I am inflated, and I want to do some of the most imaginative and groundbreaking work in Li Zheng's group forever, at the edge of science. ”

"Then ...... Try your best. Yang Jun waved his fist and said, "Although Brother Li is a very good person, why should people who can't even do a good job in topology work with him?"

Mo Nian'er glared, "What did you say?"

~" Yang Jun's legs were weak, "Brother, I was wrong......"

"No, push harder. Mo Nian gritted his teeth and unfolded the textbook, "I feel like I have fighting spirit...... Motivate me again. ”

"Ah...... Really, brother?"

"Yes, be ruthless!"

"Ahem......" Yang Jun's face turned grim, and he said stiffly, "Ordinary escort survivors still want to enter Brother Li's eyes? ”

"Right...... That's it...... Don't stop, louder, I can't hear clearly. ”

"Mo Nian, you're a waste that is good for nothing but living things. Yang Jun scolded and scolded and covered his face in shame, "As a tool person who can only do experiments, do you still expect Brother Li to look at you?"

"Uhh......hh It's hard to ......."

Mo Nian wanted to raise his head and let Yang Jun die down, but Yang Jun himself couldn't stop.

"Brother Li's eyes are only quiet, you are not worthy!"

"Don't ...... It's in the wrong direction, military ......."

Even Li Zheng and Lin Yujing in the rear raised their heads in horror.

With Mo Nian, whose face was flushed, the two of them frowned, and they couldn't help but be vigilant.

As for Cui Shenzhi on the podium, he blamed himself.

It must be that my voice is not soft enough and does not provide a good background sound, so I accidentally attracted your attention and made you distracted from self-study.

Give the teacher another chance, and I'll drop another half note.

……

This Monday is also very unusual for Shen Yuecen.

Because......

Fengfeng didn't reply to his email!

As Gui Jianfeng said, Shen Yuecen will send a few carefully selected papers to Gui Jianfeng every week, and leave a few post-class questions, Gui Jianfeng usually finishes it quickly and gives feedback, and Shen Yuecen will give the next week's papers according to this feedback for study.

But the week before, there was no reaction to the return wind.

Stayed until 12 o'clock at night, and there was still no news.

At that time, Shen Yuecen realized one thing.

What should come will always come.

Li Zheng forced the child...... Here the fuck is coming again......

Out of resentment, Shen Yuecen did not interact with Li Zheng in the math class this afternoon.

It's like a girlfriend who fights with her boyfriend every night, and suddenly one day, she copes with things and doesn't even scream.

This lesson has no taste, and Li Zheng is also tasteless.

In the teacher's lounge after class, Shen Yuecen also ignores him, but the weekly tutor is always inevitable, after all, Shen Yuecen is Li Zheng's only genuine tutor.

Whenever this happens, though, it's not so much about learning instruction......

It's more like a chatter within the family.

"Alas......" After Shen Yuecen sat down, he picked up the kettle with only one side of his head and a desolate face, "When I was young, I once met a wild cat, and I gave it food in the yard every day, and it came every day, and then there were more people who fed it, and it only came to my place to eat once in three or four days, and then later, a family gave it fish in the water, and occasionally something like pork liver and duck heart, and it never came back." ”

Li Zheng listened with a twisted face: "Grandpa...... Recent issues ...... There's really not much time to pass. Otherwise, when this period is over, I will go to you with Jingjing with the bed, you can find a bed, and we will live in it for a week. ”

Shen Yuecen almost squirted out a mouthful of water.

Looking at Li Zheng's loyal and filial eyes, he didn't even know if he was riding his face to provoke or if he really wanted to accompany the old man.

"My family is big!" Shen Yuecen was forced to wipe his mouth and scolded, "Four rooms, two of you are enough." ”

"What about you?"

"Even if I sleep on the sofa and sleep on the ground, you don't want to sleep for a ......," Shen Yuecen said and waved his hand vigorously, "That's it, it's time for young people to study, it's enough to know that you are learning, and you don't need to go through these forms." ”

"That's what you're saying. ”

"But the wind. Shen Yuecen's eyes narrowed, "What did you give him?"

"It's just a math problem in some topics......"

"Is your subject the Riemann conjecture?"

"It's superconductivity, you know. ”

"Then why did you trap him for so long?" Shen Yuecen put down the cup and shook his head, "You don't know, every time I give Gui Jianfeng a math paper, doctoral students have to gnaw on it for two weeks to get it down, not to mention understanding it throughout, but Gui Jianfeng has never made me wait for a day, have you been working on something to this depth?"

"Slightly deeper......"

"Which teacher is engaged in superconductivity is taking you? Lu Dongsheng on the experimental side, or Zhang Qi on the theoretical side?"

Li Zhengqian said: "It's the teacher who solves the conflict, you may not know it." ”

"......" Shen Yuecen's face was stunned, and he didn't say anything for a long time, and finally said stiffly, "That's right...... It's going to be a while before I come back......"

"What?"

"Fish in the water, pork liver and duck heart. Shen Yuecen couldn't help but shake his head, "That cat smells this, can it still eat my family's leftovers?"

"......" Li Zheng swallowed and foamed, "You may have misunderstood, Gui Jianfeng has never met with Teacher Xie, and the questions asked Gui Jianfeng are all from me." ”

Shen Yuecen raised his hand and nodded to the table: "Can you say that there is no idea of resolving the dispute here?"

“…… I can't say that absolutely. ”

Shen Yuecen pointed at his head and said: "For people like them who are extremely smart, burying a button in the equation is enough to dig to the end." ”

Li Zheng scratched his head and said, "I'...... I don't think there's anything strange about it......"

"We are different, we are stupid people, we make up for our clumsiness, and we are just knowledgeable. Shen Yuecen sighed, leaned back in the chair for a long time, and then said, "At that time, you wanted to engage in superconductivity theory, and I didn't object to it, but you also promised some things, do you remember?"

"Yes. Li Zheng nodded immediately, "Limited to this semester, if there is no clear sign of results at the end of the semester, the project will end here." ”

"I'll give you some more grace, before the Spring Festival. Shen Yuecen raised his hand and said, "If you can't see hope at that time, just rest and rest." The so-called not hitting the south wall and not looking back is not a bad thing, but in some places, there is not even a wall, it is just pure endless. Or maybe there is a wall, but there is still no end to challenging it on the scale of a short life. ”

"Yes. Li Zheng then sighed, "You can at least allow us to follow along to resolve the disputes, which is already more enlightened than most teachers." ”

"Allowed, I don't allow it to work?" Shen Yuecen pointed at Li Zheng and scolded with a smile, "I don't allow you to skip class, and you don't want to be quiet outside of class...... Does it work?"

"Hey~"

"Hippie smiley. Shen Yuecen raised his hand and said, "Go ahead, solve the problem, you won't die." ”

"It's okay, it's very happy, let's count it with Jingjing. ”

"???" When Shen Yuecen reacted and wanted to find something to smoke Li Zheng, he was forced to run away, and only obscene laughter was still echoing in the corridor.

Shen Yuecen smiled helplessly, so he had to put on leather shoes again.

"Thirty years...... He should be able to control this measure. ”

……

After dinner, in the experimental classroom, as night falls, the sun that belongs to the trio rises as usual.

Li Zheng asked while arranging the tools on the table, "How is Auntie?"

"What?" said Xie Qifen, wiping the small whiteboard.

"Didn't you take your mother to the hospital on the weekend?"

"Oooh...... It's fine, routine checks. Xie Qifeng raised the black pen and said, "What about your side, are you interested in seeing the wind?"

"No—often interested. Lin Yujing also pulled her own small whiteboard, crossed her arms and gestured, "Forget it, I don't bring hunger for a day, I'm starving and fainting from the side." ”

"Can you faint from hunger?"

"Yes, that's what Li Zheng said. Lin Yujing said pitifully, "Anyway, when I woke up, I was already on the ground......

"What about the memories from before?" Xie Qifen rubbed his forehead and said, "I can remember the state before the break when I drank a fragment." ”

"Before...... Before...... Lin Yujing nodded his chin and said, "It seemed to be quite comfortable before, where did you lie down...... Where did ...... come from?"

"Ahem, it doesn't matter. Li Zheng once again erased Lin Yujing's memory with a loud voice, and then broke through his disagreement, "Guijian Feng seems to have raised the magic horn calculation twice, and it may have to use eight yuan." ”

"yes, yes, I skipped all of this when I read string theory before. Lin Yujing then asked, "Later, I found out that it is not only string theory, but also related to quantum logic, why didn't you tell us about it?"

"This ...... Mathematical expansion is another direction that is not necessarily related to superconductivity. "Let's go ahead and talk about ours, I'll go back and calculate the five sets of solutions simulated by the computer in the paper, three of them have no problems, and the other two groups should have a lot of errors." ”

Li Zheng and Lin Yujing had just picked up their chairs and were about to come up, when a heavy and then immature wheezing sound suddenly came from the door.

"Right...... That's right!" A boy with messy hair stared at the door, "Of the five standard solutions, three groups need to take into account extraterritorial ......"

"Fengfeng!"

"See the wind?!"

Li Zheng and Lin Yujing hurriedly got up and helped them over.

They were really frightened by the unkempt state of the wind.

"I came directly to the school, and Teacher Shen told me that you are here......" Gui Jianfeng was held all the way, and asked excitedly all the way, "Although all you gave me are numbers, this is actually a very deep quantum problem, right????"

"Hmm...... Is superconducting...... But down to this scale, it's really a quantum problem. Li Zheng said in a trembling voice, "You can reverse this......"

"It's not the key, the key is the three sets of virtual solutions...... "Seeing the wind shaking the paper in his hand and nodding constantly, "the virtual solution unfolded...... A new image unfolded...... Plus those 5 solutions...... 8 pips...... 8 pips...... All on one axis!!"

"What are you talking about??" Li Zheng was completely confused, "Isn't the solution here an angle, the traditional five solutions are only five angles, what is the matter with the key point and axis?"

"We've expanded a long time ago, have you forgotten!" Gui Jianfeng grabbed Li Zheng's arm and said, "Now it's a new number domain and space...... Judging by this new space...... These 8 solutions are all on one axis, it's amazing! You tell me that this is the result of a physical simulation experiment...... Let me count the coincidences of meeting special conditions, and I will figure it out...... But why are they on one axis? It's like an infinitely thin needle that pierces eight planes...... I don't know what to call it...... What the hell is it called...... You're good at language, you're ......."

Just when he saw that the wind was going crazy, he panicked.

A freezing sound pierced in.

"Tunneling paths. ”

"That's what it means!!Good name!!" Seeing the wind, he hurriedly turned his head.

He only saw a man with a stagnant look and a stiff face.

"Who told you to be a hypocrisy?" asked Xie Qifen word by word.

"I ...... I'll just ...... I feel it......" Gui Mifeng sighed, "those numbers are here...... Isn't that natural...... You must know there's something out there......"

"You're more ...... than I thought And ......" Xie Qifen was a little slurred, and after trying a few times, he stiffened up, "I'll go out for a cigarette and let him rest." ”

"Hey......" Li Zheng hurriedly pulled a handful of people, "It's hard not to smoke, so don't smoke anymore." ”

"Got it, thanks, let go. "Solve the coldness and say coldly.

After he walked away for a while, Gui Jianfeng asked, "What's wrong...... Why is everyone so unhappy...... Shouldn't you be happy to solve it?"

"Yes, but you...... Maybe it's too much. Li Zheng rubbed his head to appease Gui Jianfeng, and at the same time rushed to Lin Yujing, "Do you understand?"

"I ...... Give it a try. Lin Yujing walked to the whiteboard and worked hard to draw and describe.

"Imagine a plane with 5 singularities spread out on it. ”

"The two-dimensional people on the plane know that these points are magical, and they have worked hard for a long time, but they have not found any reliable laws and models. ”

It wasn't until Gui Mi Feng appeared that he calculated that there were three such singularities beyond the plane, where two-dimensional people could not see. ”

"This kind of thing that exists in theory is nothing. ”

But the problem is that Gui Jianfeng's mathematical thinking is too strong, he looks at the 8 points as if he thinks of something, and then ...... Then he thought mathematically...... There is an angle, and from there, the 8 points are on a one-dimensional axis. ”

Lin Yujing said and made a gesture of kneading paper balls.

"It's like folding and curling a two-dimensional plane, and then piercing it with a needle, and penetrating the two-dimensional plane exactly eight times, three of which are theoretical penetrations...... Don't look at me like that, Li Zheng, I don't know exactly what I'm talking about......"

"Anyway, Gui Mifeng thought it was a crazy discovery, but couldn't think of a name......"

"At this time, an old commentator—"

"Tunneling paths. ”

Lin Yujing covered her face with one hand and spread it out with the other: "I'...... I worked hard......"

"Very good!!" Gui Jianfeng nodded hurriedly and looked at Li Zheng expectantly, "Although it is not rigorous, but it probably means this, you should be able to understand it now, right?"

"I ......"

Li Zheng's brows gradually sank.

Liu Xin......

I, I shouldn't have done that to you......

I'm sorry.
