Learning Demon Cultivation System

A lot of people from outside also poured in, filling the classroom in no time.

Xie Qifen shook his head, asked Lu Yang for a bottle of mineral water, took two sips and started speaking again.

In an instant, the tenderness was gone, and the content returned to what I told Li Zheng at the beginning.

Cut into pieces, then micro a moment, all came out.

It belongs to the kind of rhythm that simply taking notes can't keep up.

gradually……

The number of people began to decrease...

"Excuse me, Mr. Xie..."

"These... you can't pass the exam at all..."

"Why do I feel like I'm listening to Mathematical Analysis..."

"Let's go back to sleep..."

"Li Zheng, can you understand this?"

After more than 20 minutes, all the people who had just squeezed in were squeezed out again.

Only Qi Yingnan with thick eyebrows and big eyes was left, sitting at the farthest place from Li Zheng, and he just listened hard.

Seeing his constipated expression, Xie Qifan also smiled, dropped the chalk and asked, "To be honest, how much do you understand?"

"Zero!" Qi Yingnan replied vigorously.

"Then what are you listening to?"

"The truth of physics!" Qi Yingnan didn't give in at all, and nodded in a daze, "You asked at the beginning, who wants to get close to the truth of physics, I think."

"Oh? Are you still asking this?" Li Zheng in the back row said in surprise, "Then I want to too."

"Ignore you." Qi Yingnan shook his head, as if holding grudges, and didn't care about Li Zheng at all.

Xie Qifan glanced at his watch, then at the two of them, couldn't help but shook his head and sighed: "It's past ten o'clock, look at the virtues of the two of you. Then let me talk a little bit, I'm just a leader of imagination, Don't think too deeply."

As he said, he turned and pointed to the puddle of water just drawn on the blackboard: "What I have been teaching just now is nothing more than describing physical problems into physical images and transforming them into mathematical problems for solving, right?"

The two nodded in unison.

"The other way around?" Xie Qifen picked up the eraser and wiped away the puddle of 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 then fell into thinking.

Then, Qi Yingnan raised his hand first: "No."

"why?"

"This mathematical equation is too simple and can only describe the fluid state of a certain state in a physical environment."

"Very good." Xie Qifan 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're fine too." Xie Qifan nodded, and then looked at Qi Yingnan, "Describing physics with simple equations is actually what the sages of the classical physics era did."

After finishing speaking, he turned to Li Zheng: "Now, scientists are doing their best to deduce the equations that describe everything. There will be many, many groups. This is why modern science is too complicated."

"Quantum mechanics, which I hate the most, is also one of them."

"It's not that quantum mechanics is necessarily wrong, on the contrary, I understand quantum mechanics better than most so-called experts, but that doesn't stop me from hating it."

"I hate it because my math is so good that I disapprove of it intuitively and hate it physically."

"It creates a lot of unreasonable concepts that cover up the key points that are difficult to describe in mathematics. To me, they are like magic sticks, using their own words to create a bunch of plausible causes and effects, and then erect extremely high knowledge. threshold."

"Some of the most disgusting people claim that they have the ability to 'interpret the oracle', so they are looked up to by a bunch of people who don't understand, cheated, cheated, cheated and beaten."

"For me, physics must satisfy mathematics, otherwise I would be disgusted, just like seeing a group of people preaching with the Bible."

"But I'm not much better off if I don't talk about it."

"I have my bible, too—mathematics."

"This is the only unshakable thing I can accept, the only reliable achievement of mankind."

"So, when I realized that I rejected quantum mechanics and at the same time didn't have the experimental talent."

"I picked up my Bible."

"If they're all working backwards from physical images to deduce mathematical formulas."

"Then I'll do the reverse, using math..."

"cough."

Li Zheng and Qi Yingnan were listening intently, when a moderate cough suddenly came from the door of the classroom.

The three looked at the past at the same time.

The person who came was a tall man in a suit. He should not be too old, but his hair was already grey. Against the backdrop of rimless glasses and a kind smile, he could be regarded as the kind of person who would definitely think that he was just a glance at him. Very knowledgeable appearance.

Even to solve the problem, he put down the chalk and nodded obediently: "Dean Zhong..."

"It's okay, it's exciting." The man raised his arm and nodded his watch with a smile, "It's just a little late today."

"Yes..." Xie Qifan hurriedly lowered his head and packed up his things, the exuberant look before was gone.

It seems that the school ruffian is just bullying and fearing the hard, and immediately dare not speak when he sees the real boss.

But Li Zheng didn't pay attention to this, he really wanted to say "I'm not sleepy".

But the big boss is also a real big boss. Dean Zhong only stood in front of the door with a smile, and Li Zheng consciously stopped talking, unable to say a word.

Qi Yingnan went too far, looking at the big brother's kind face, he was already trembling a little.

On the other side, in front of the podium, after clearing things up in twos and twos, they walked out with a sullen head.

Instead, Dean Zhong raised his hand to stop him and said, "This batch of teachers from the meeting are back. Thank you for your hard work, let's say goodbye to the students anyway."

"Oh..." Xie Qifan waved his hands at the two of them copiously, "I've said everything that needs to be said, and the rest is for myself to understand, let's meet again when we have a chance..."

Before the two of them could reply, he nodded to the dean and left in a hurry.

Under the watchful eyes of Li Zheng and Qi Yingnan, Dean Zhong walked in with a smile, sat down at a table, put down his briefcase and said with a smile, "One of you must be Li Zheng, right?"

"Ah." Li Zheng responded blankly.

"Zhou Yi specifically mentioned something to me." Dean Zhong raised his finger and pointed at Li Zheng and smiled more presumptuously, "Let me make things difficult for you."

Li Zheng stared.

Hello Zhou Chenghuan!

Isn't it enough to give me a ring-forming question like honeycomb coal?

Dean Zhong looked at Qi Yingnan again: "This classmate is..."

Qi Yingnan was startled, and stood up in shock: "Qi Yingnan... the number one... the fourth."

"Well, they are all very good grades." Dean Zhong nodded affirmatively, and asked casually, "What did Teacher Xie say just now?"

Hearing this question, Li Zheng and Qi Yingnan immediately looked at each other, then bowed their heads together.

Dean Zhong coughed too much. It's about time.

Plus a series of strange performances.

Both of them could feel that both the dean and Xie Qifen seemed to think that the content after this class was taboo.

Although the two of them were in awe of the dean, they were unwilling to just pretend to understand their differences.

"Okay, don't be nervous." Dean Zhong just raised his hand and smiled, "If he talked about cellular automata or the game of life, it would be very interesting, but you are far from deep immersion. Mr. Xie Talent is recognized, but its depth of thinking and research methods are not acceptable to everyone. If you can enroll, it is not too late for you to ask for advice."

This is awkward.

Dean Zhong's original intention was to vaccinate them, so as not to lead the two of them astray.

However, Xie Qifen didn't say that much at all.

Instead, he personally sent the words "cellular automaton" and "game of life" to the two of them.

Dean Zhong looked at the rolling 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, held his nose and got up awkwardly, "Go back to the dormitory, I will make up the opening ceremony for you tomorrow morning."

Li Zheng and Qi Yingnan hurriedly got up and packed their things. After saying goodbye to the dean, they ran into the stairwell quickly.

At this moment, Qi Yingnan also forgot to remember Li Zheng's grudge, and as soon as he entered the corridor, he took Li Zheng's hand and shouted: "Cellular automaton?"

"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 mathematics, and mathematics has something to do with physics."

"Oh, I'm so anxious, what the hell are you doing!"

"Yeah, is it necessary to be so mysterious? It's not a perpetual motion machine."

Just as he was talking, a person rushed up from downstairs.

Fortunately, it wasn't the solution, it was Lu Yang.

Lu Yang is a really kind person, he didn't forget to take them to the dormitory right now.

They caught Lu Yang, of course they wouldn't let it go, and even if they asked about things they knew about him.

It's a pity that even Lu Yang doesn't know what kind of research Mr. Xie is doing and what kind of physics thinking is.

Lu Yang only knew that his research was stopped more than ten years ago, and Xie Qifen never did any research after that.

What stopped was not only research, but also the enthusiasm for life.

Xie Qifan still lives with his mother and has no intention of getting married or starting a family.

Although he hasn't commented on the title of professor so far, his image and qualifications are first-class. Over the years, many girls in the school have expressed their admiration, but he has thrown them away one by one like splashing water.

In the few years after the project was suspended, the leaders of the institute offered projects and funds to their mouths several times, but he didn't want them, and he didn't sign up when he was asked to evaluate the titles.

According to Lu Yang, this is probably a kind of resistance to the suspension of research.

If you don't want me to do this, then I will do nothing.

Of course, this kind of resistance must be a man's arms.

As Xie Qifen got older and more talents were added, he became a marginal figure, teaching those few classes every week. If it weren't for the various meetings colliding with each other these days, it wouldn't be his turn. Come bring camp.

"So, scientific research is like this." Lu Yang and the two walked slowly by the unknown lake, looking at the moon shadow on the lake and sighed, "No one knows where the right direction is, and no one knows whether it will be blocked or not. Stop it, no one knows whether to persist. Each professor is like a tree root spreading out in all directions. I just hope that in this life, I can reach a deeper place, touch more soil, and not hit a dead end. gone."

"Senior has a good literary talent." Li Zheng praised, "So you still don't know the direction of Teacher Xie?"

"I don't know... Some teachers may know, but they don't say anything, and we will get angry when we ask."

Qi Yingnan smiled and said, "Why is it like Voldemort in Harry Potter?"

"It's really about the same." Lu Yang gestured, "This is also the seventh of the seven taboos in our Academy of Sciences - the research to solve it."

"What about the first six?" Li Zheng and Qi Yingnan asked in unison.

"I don't know much, and I can't tell you if I know."

"Just say one."

"Please, Brother Lu Yang." Qi Yingnan flickered on Lu Yang's arm and acted coquettishly.

"Get out!" Lu Yang threw it away, and reluctantly said, "Then tell the two of you...you saw Dean Zhong just now, right?"

"Ah."

"Hmph..." Lu Yang looked at the two, gradually gritted his teeth, and said in a very low voice, "Dean Zhong... used to be the person next door..."

"A person from Jinghua?" Qi Yingnan asked in surprise, "A person from Jinghua came to be the dean of Ji University?"

"Hush!" Lu Yang said vigilantly, "Don't mention this in front of too many people... This is starting a war."

"Such seriousness is the second taboo..." Li Zheng asked, "What is the first one?"

"I don't know, probably only graduate students are qualified to spy on one or two." Lu Yang hugged the two of them and said, "You just need to know 'study physics, come to Ji University'. Of course it's not just physics, 'study chemistry' There is nothing wrong with coming to Ji University, "come to Ji University to study biology", "come to Ji University to study business management"..."

"Why do you look like Lan Xiang?"

"Shut up! Lan Xiang is next door."
