Xie Qi led Li Zheng out of the school, and found a familiar Sichuan-style snack restaurant. He ordered a few plates of hot and spicy dishes, and then chatted with a bottle of wine.
As soon as he drank the wine, he was more talkative than usual, and the topic was more jumping.
I was just talking about mechanics, and suddenly sprayed quantum.
Spraying spraying extends to Schrodinger's open marriage. How can the upright wife and concubines be in groups, the red flag at home does not fall, and the colorful flags flutter across the city.
Then, on the subject of drought and waterlogging, the topic changed strangely to the "suppression of science students", saying that he had wanted to do a paper on "the correlation between scientific research efficiency" when he was an undergraduate, and was rejected. But he felt that this direction was possible, so he modified the topic and changed it to "impact on IQ", and then there was no more.
He still thinks that this topic cannot be done, not because it is not reliable, but just to take care of the self-esteem of the majority of science students.
When chatting here, Li Zheng couldn't hold back a bit, and wanted to get the topic back to learning, so he asked a fluid mechanics question.
Solve their problems and not hesitate to enlighten me, and immediately gave Li Zheng a topic
【Fluid Mechanics Analysis】
Looking at Li Zheng's stiff face after hearing the selected topic, he was very appreciative.
"Look, what a big topic this question is." Xie Qi laughed, sullen at the beer.
Li Zheng coughed: "There is a man named Bi Dao in the bar. He may be interested in this topic."
"No." Xie Qi raised his hand resolutely, "such a good topic cannot be given to elites."
"Do you seriously understand the teacher... what is the point of this topic selection?"
"Yes, the application prospect is very broad." Xie Qi said, "I will say a few things?"
"This... it seems that medicine has been solved."
"Can that be the same? Don't you think physics is more interesting?"
"Okay..." Li Zheng shook his head and said with some hesitation, "Of course it's okay to talk about these while eating...but I still care more about the topic you are really doing. These things sound like,..."
"Minke?" Xie Qi smiled and opened a new bottle of wine. "It's okay, just say, I have been sprayed like this for more than ten years."
"No, I want to say Doraemon."
"Haha, it doesn't matter." Xie Qi's dull and half-bottle, looking at Li Zheng's eyes, he finally couldn't refuse to sigh, "I don't do anything now, if someone is willing to give money... "
"..."
"Okay, I know you are annoying me." Xie Qi put down the bottle and grabbed two dishes. "Hurry up and go back and give you a lecture."
"It's not annoying, teacher." Li Zheng picked up the bottle instead and poured himself half a glass. "It's just that with someone like you, I would unconsciously want to absorb the nutrients in physics and want to know. What kind of research did the early champion like you have done, and what kind of content did you think about?"
"Study, think?" Xie Qi shook his head and sang the tiger dish. "It's still early, Comrade Xiao Li, it's not that I don't want to say, it's because you shouldn't listen now."
"It's okay..." Li Zheng sincerely toasted, "I'm mentally prepared, even if you are really a perpetual motion machine, I can accept it. Without telling you, I trusted your knowledge at the beginning and doubted you very much 'S personality... Now it's the other way round. I trust your personality very much, but I start to doubt my knowledge..."
Xie Qi was stunned for a while, but he quickly picked up the bottle and bumped into Li Zheng again.
"Thank you for your trust." Xie Qi occasionally got serious and stared at Li Zhengdao, "I will show you my way of thinking and training methods as much as possible. But I really think about physics, sorry, now Not yet."
"why?"
"No, it's not good." Xie Qi put down the bottle, his face was no longer frowning, but he was covered with a layer of numbness.
Li Zheng said nothing, and he wouldn't answer, even if he said anything about doubling up.
He just pulled out his phone and walked to the counter a little skewed, leaving only the back of an ordinary middle-aged drunkard.
On the way back, the two did not say a word.
When I returned to the small classroom, it was already 8 o'clock in the evening. In the large experimental classroom next to me, the people in the training team were still doing experiments.
Xie Qifan was not interested in this, just returned to the blackboard and scribbled casually.
Although he was a bit drunk, he wasn't too interested, but the content he spoke was still remarkable.
"A few hours ago, you learned a new way to solve problems."
"Draw a physical image, and then convert it into a mathematical problem, and restore the physical result after calculation."
"This is not really a new method. From middle school, physics problems can be solved in this way."
"It's just that now, after mastering the micro-sum product, there is no longer any obstacle to the conversion between physics and mathematics."
"But this does not mean that all physical problems can only be transformed by calculus."
"In other words, calculus is the dumbest method."
"Do you know the picture on the computer? It is to divide a picture into millions of pixels, and then display the entire picture by describing the color of each pixel. This is the most stupid way."
"If you are smarter, we can record the characteristics of the picture to describe it."
"For example, in a picture, the 1 million pixels in the upper left corner are all black. We only need to record the position of the critical point and the black information."
"And this is Euler's description in fluid mechanics."
"Next, let's put down the idea of ​​switching calculus, let's take a thinking journey with Lao Ou together."
The following class, unlike the initial mean jump, gradually became gentler, and many guides and examples that were easy to understand were added to make the whole class soft and comfortable.
Of course, where mathematics is involved, it is still very steep, and it always suddenly "slightly", and then Mao can not understand.
I don't know how long it took, and suddenly there was a knock on the door.
After answering their questions, the two boys stepped into the classroom, watching Li Zheng reconciling them, with a bit of sorrow in his eyes.
Li Zheng noticed that there were more people gathered at the door of the classroom. Lu Yang was trying to get everyone away, but he couldn't move.
Xie Qi rubbed his head, and it might be that Jiujiner came up, and asked anxiously, "What's wrong?"
"Teacher Xie...we want to hear..."
"You can't just give him a small stove and push us all out..."
When these two sentences are spoken, the outside is quiet.
"Listen." Xie Qi pointed to the empty seats in the classroom. "I'll let you listen. You're sitting."
The two were stunned, then immediately happy, and quickly found a seat to sit down.
A lot of people outside also poured in, and in a moment they filled the classroom.
Xie Qiwan shook his head, asked Lu Yang to ask for a bottle of mineral water, and gave it a second talk again.
In an instant, gentleness ceased, and the content returned to what Li Zheng originally told.
Cut it into pieces, and then a little bit, it's all out.
It's a rhythm that you can't keep up with just taking notes.
gradually……
People began to decrease...
"Excuse me, teacher Xie..."
"These...can't even take the exam..."
"How do I feel listening to "Mathematical Analysis"..."
"Go back to sleep..."
"Li Zheng, can you understand this?"
For more than twenty minutes, the people who just squeezed in all squeezed out again.
Only Qi Yingnan, who had a big eyebrow and big eyes, was sitting in the place farthest from Li Zheng, and he listened hard.
Xie Qi looked at his constipation-like expression and smiled. He dropped the chalk and asked, "To be honest, how much did you understand?"
"Zero!" Qi Yingnan answered Zhenzhen.
"So what do you listen to?"
"The truth of physics!" Qi Yingnan didn't give up, and nodded stupidly. "You asked from the beginning, who wants to get close to the truth of physics, I think."
"Oh? Did you ask this again?" Li Zheng in the back row startled, "Then I think too."
"Ignore you." Qi Yingnan shook his head, seeming to be vengeful, not Li Zheng at all.
Xie Qi looked at his watch and looked at the two again. He could not help shaking his head and sighed, "It's more than ten o'clock, look at the virtue of both of you. Then let me talk a little bit, just the imaginative head, Don’t think too deeply.

He said, turning back and pointing to the tuoshui that was just drawn on the blackboard: "What I have just taught is nothing more than describing physical problems as physical images and transforming them into mathematical problem solving, right?"
The two nodded together.
"The other way around?" Xie Qi picked up the wiper and wiped off the sloppy water, leaving only the equation next to it. "I only give you the mathematical equation. Can you describe the physical image?"
The two were startled, and immediately fell into thought.
Then, Qi Yingnan took the lead in raising his hand: "No."
"why?"
"This mathematical equation is too simple and can only describe a specific state of fluid state in a physical environment."
"Very good." Xie Qi turned to Li Zheng, "What do you think?"
"Still thinking..." Li Zheng pondered, "What if there are more equations? Enough to cover everything in this fluid?"
"You are also very good." Xie Qi nodded, then looked at Qi Yingnan, "using simple equations to describe physics, in fact, this is what the sages did in the classic physics era."
In short, he turned to Li Zheng: "Now, scientists are trying to perform equations that describe everything as much as possible, and there will be many, many groups, which is why modern science is so complicated."
"Quantum mechanics that I hate the most is one of them."
"It's not that quantum mechanics must be wrong. On the contrary, I understand quantum mechanics better than most so-called experts, but that doesn't prevent me from hating it."
"I hate it because my math is so good that I don't recognize it intuitively, and I hate it physiologically."
"It creates a lot of irrational concepts that cover the key points that are difficult to describe in mathematics. In my case, they are like sticks, using their own words to create a pile of specious causation, and then erected a very high level of knowledge. threshold."
"Some of the most disgusting people claimed that they possessed the ability to "interpret the oracles", so they were looked up by a bunch of people who didn't understand, and cheated on eating and drinking.
"Here, physics must satisfy mathematics, otherwise I am sick, just like seeing a group of people holding Bible preaching."
"But I'm not much better than what I said."
"I also have my Bible-mathematics."
"This is what I can accept, the only unshakable thing, the only reliable achievement of mankind."
"So, when I realize that I am repelling quantum mechanics, and at the same time I don't have the experimental talent."
"I picked up my Bible."
"If they are all using physical images to deduce mathematical formulas."
"Then I will turn it over and use math..."
"cough."
Li Zheng and Qi Yingnan heard the sound, and a loud and heavy cough suddenly came from the classroom door.
The three looked at the same time.
The visitor is a tall man in a suit. The age should not be too big, but his hair is already gray. With frameless glasses and a kind smile, it can be regarded as a kind of only one glance. Very learned look.
Even if it is to resolve the dispute, put down the chalk and nod and salute: "Chief Zhong..."
"It's okay, it's wonderful." The man smiled with his arm nodded, "It's just a little late today."
"Yes..." Xie Qi bowed his head quickly to pick up things, before the frantic look disappeared.
It seems that Xuepi is just bullying and afraid, and when he sees the real boss, he dare not speak.
However, Li Zheng did not pay attention to this. He wanted to call out and say, "I am not sleepy."
But the boss is also a real boss. Dean Zhong only smiled for a stop in front of the door, and Li Zheng consciously closed his voice, unable to say a word.
Qi Yingnan was even more overwhelmed, watching the big brother's kind face already trembling.
On the other side, in front of the rostrum, they solved it after two or three times, and then walked out with their heads blank.
Instead, Dean Zhong raised his hand and stopped, saying: "The teachers in this group have returned. You have worked hard, and you should treat your students individually."
"Oh..." Xie Qifu waved his hands at the two of them, "We should talk about everything, and the rest is our own understanding. Let's see you again..."
Before the two men answered, he nodded to the dean and left in a hurry.
Under the gaze of Li Zheng and Qi Yingnan, Dean Zhong walked in with a smile, and sat casually at a table, put down his briefcase and smiled: "Must one of you be Li Zheng?"
"Ah." Li Zheng responded dumbly.
"Zhou Yi specially mentioned this to me." Dean Zhong raised his finger and smiled more arrogantly, "Let me embarrass you."
Li Zheng stared.
Well you are in a circle!
Isn't it enough to give me a ring-like problem like honeycomb?
Dean Zhong looked at Qi Yingnan again: "This classmate is..."
Qi Yingnan was agitated and got up in shock: "Qi Yingnan...the first...the fourth."
"Well, they are all very good results." Dean Zhong nodded and asked casually, "What did the teacher just say?"
Upon hearing this question, Li Zheng and Qi Yingnan immediately looked at each other, and then bowed their heads together.
It's time for President Zhong to cough.
Plus a series of strange performances.
The two of them could feel that whether it was the dean or his own, it seemed that the content behind this lesson was taboo.
Although the two people were in awe of the dean, they did not want to sell them to understand their differences.
"Okay, don't be nervous." Dean Zhong only raised his hand and smiled, "If he talks about cellular automata or life games, it is really interesting, but you are still far from being deeply immersed in it. Teacher Xie's Talent is recognized, but its depth of thinking and research methods are not acceptable to everyone. If you can enter the school, you are not too late to ask for advice."
This is embarrassing.
Dean Zhong’s original intention was to give preventive shots to prevent them from twisting the two.
However, there is not much to say about it.
Instead, he personally sent the words "Cellular Automaton" and "Life Game" to the two.
Dean Zhong looked at the turning eyes of the two, and seemed to realize something.
"Okay, don't think about it...the smell of smoke in this room...really..." He swallowed and snorted, covering his nose embarrassedly, "Go back to the dormitory, and I will fill up the opening ceremony for you tomorrow morning."
Li Zheng and Qi Yingnan got up and packed their things. After saying goodbye to the dean, they quickly ran into the stairwell.
At this time, Qi Yingnan also forgot to remember Li Zheng's hatred. As soon as he entered the corridor, he took Li Zheng's hand and shouted, "Cellular automata?"
"Game of life!" Li Zheng was equally excited.
"But what does this have to do with physics?"
"At least it has something to do with math, and math has something to do with physics."
"Oh, I'm so anxious, to understand what he is doing!"
"Yeah, is it necessary to be so mysterious, and not a perpetual motion machine."
As he said, a man hurried up from the downstairs.
Fortunately, it's not Lu Yang.
Lu Yang is a really nice person, and I don’t forget to take them to the dormitory building.
After catching Lu Yang, of course they will not let go, even if they ask about the things they know.
It is a pity that what Teacher Xie did in the end, what kind of physics thought was, even Lu Yang did not know.
Lu Yang only knew that his research had been stopped more than ten years ago, and since then he has not done any research.
What stops is not just research, but also the enthusiasm of life.
Xie Qifan still lives with his mother to this day, without any intention of getting married and starting a family.
Although he has not evaluated the title of professor so far, his image and seniority are one-on-one. Over the years, many girls in the school have expressed admiration, but he has thrown away everyone like a splash of water.
In the years after the project was stopped, the leadership of the college had sent the subject and funds to his mouth several times. He did not want to ask him to evaluate his job title, and he did not sign up. It has completely become a state of old Lai.
According to Lu Yang's words, this is probably a kind of rebellion against being stopped.
If you don't want me to do this, then I will do nothing.
Of course, this kind of resistance must be trivial.
As Xie Qi got older, and more talents were added, he became a fringe figure. He taught a few classes every week. If it weren’t for the various meetings these days, it wouldn’t be his turn. Come to bring training camp.
"So, scientific research is like this." Lu Yang and the two walked slowly on the bank of Anonymous Lake, watching the moon shadow rising over the lake and sighed, "No one knows where the right direction is, and no one knows whether it will be Stop, no one knows whether to persevere. Professors, like the roots of a tree spreading out, just want to reach deeper in this life, touch more soil, don’t hit the dead end. Now."
"Senior is good at writing." Li Zheng exclaimed, "So you still don't know the direction of Teacher Xie?"
"I don't know... some teachers may know, but they don't say it, we get angry when we ask."
Qi Yingnan laughed: "How is it like Voldemort in Harry Potter?"
"It's almost the same." Lu Yang said, "This is also the seventh of the seven taboos of our yard-a study to solve its problems."
"What about the first six?" Li Zheng and Qi Yingnan asked in unison.
"I don't know much, and I can't tell you about it."
"Just say one."
"I beg you, brother Lu Yang." Qi Yingnan flirted with Yang's arm.
"Go!" Lu Yang threw it away and said reluctantly, "Then tell you the second one... You just saw Dean Zhong, right?"
"Ok."
"Humph..." Lu Yang looked at the two, gradually gritting his teeth, and said in a very low voice, "President Zhong... used to be the person next door..."
"The elite?" Qi Yingnan exclaimed, "The elite people come to Ji Da as the dean?"
"Hush!" Lu Yang said vigilantly, "Don't mention this to too many people... this is a war."
"Such a serious problem is the second taboo..." Li Zheng asked, "What is one of them?"
"I don't know. Probably only graduate students are eligible to spy on one or two." Lu Yang embraced the two humanities. "You just need to know'Learn physics, come to Jida'. That's more than physics,'Learn chemistry. It’s okay to come to Jida University,'Students come to Jida University','Learn enterprise management to Jade University...'"
"How is it like Lan Xiang?"
"Shut up! Lan Xiang is next door."
