After falling into the carnival of discussion, Lin Xiufeng walked in again, stood on the podium and bowed to Li Zhen:

"Dean Li, I would like to ask you to give a lecture. In a different position, I'll listen. ”

"Lecture as usual. I would like to hear your lessons. ”

Li Zhen nodded, there was no nonsense, and immediately walked to the podium.

The moment Li Zhen walked to the podium, everyone on the podium ran down and sat down.

Those who left the venue early, as soon as they heard the news that Li Zhen was going to start lecturing, they ran back with a roll. They were all forced by Lin Xiufeng's chatter and left halfway.

In the auditorium, there was an instant silence. The teachers sent by the imperial court immediately sat down, holding their breath, looking forward to it, and nervous.

A person who has been able to cultivate so many amazing talents with his own efforts. What should he teach?

"I didn't prepare a lesson plan today, where did I talk about it yesterday?"

Li Zhen stood on the podium with a triangular ruler in his hand. I don't feel comfortable not holding something in my hand.

Liu Jinghong shouted: "It's time to talk about aerodynamics." ”

Hiss –

The teachers gasped.

Aerodynamics!

That lost knowledge, that discipline that can make human beings fly into the blue sky? The shocking statement?

Lin Xiufeng's eyes widened, as a senior lecturer in physics, he had naturally heard of aerodynamics. But literally, it is impossible to understand what the relationship between air and power is, and why.

It's so terrifying, has the Kyushu Institute of Physics entered this level? What are the stages of studying aerodynamics?

Li Zhen patted the table: "Be quiet." ”

"To understand aerodynamics, we first need to know a concept. Fluid dynamics. Have I mentioned fluid mechanics before? Who remembers? ”

"Me."

"I remember!"

"Master Li, I remember. 、”

"I remember too."

“……”

In the auditorium, everyone immediately raised their hands and shouted. It is a great honor to be named by Li Zhen to answer the question, and to answer it.

But unfortunately, Li Zhen usually doesn't ask questions by name. And in general, no one can answer the question......

Those teachers looked at the fiery atmosphere in amazement, this ...... What is fluid mechanics again? I've never heard of it.

And, how do so many people know? How come we don't know?

Lin Xiufeng looked at Li Zhen anxiously, how eager he wanted Li Zhen to repeat the previous lesson. He knew he must be lagging behind, he must have missed too much.

But it can't be. Li Zhen never repeats. If you understand it, you can listen to it, and if you don't understand it, forget it.

Li Zhen looked at the oldest person in the Kyushu Institute of Physics: "Tell me." ”

The white-bearded and white-haired old man stood up excitedly: "Master Li, you mentioned that fluid mechanics is a branch of mechanics. ”

Li Zhen asked: "What else?" ”

"Uh...... Also, there's something you haven't talked about yet. The old man's tone became cramped.

Everyone was silent, not daring to breathe. If you can't answer it...... The situation is very serious.

Li Zhen frowned: "You sit down." ”

"Yes, Master Li." The old man sat down ashamedly, his face flushed.

"Ladies and gentlemen, fluid mechanics is a branch of mechanics, do you still know mechanics?"

"Yes."

And the crowd said, Look at me, and I will look at you. I don't dare to answer casually, although I really know mechanics, Li Zhen has talked about mechanics, and everyone has studied mechanics. But no one has the courage to volunteer to answer at this time, what if they can't answer again?

"Fluid mechanics is a branch of mechanics, and aerodynamics is a branch of fluid mechanics. Remember, that's the point. If you want to study aerodynamics, you need to start with fluid mechanics. First know what fluid mechanics is, and only when you are proficient in fluid mechanics can you understand what aerodynamics is. ”

Before Li Zhen finished speaking, the entire auditorium fell silent for an instant, and then there was a 'rustling' sound.

The teachers looked around, only to see that everyone in the entire auditorium began to write frantically in their notebooks in various postures. The writing was so fast and scribbled that only they could recognize.

Lin Xiufeng's face was full of embarrassment, this is Li Zhen's authority. Giving a lecture on the podium by himself, some yawned, some were impatient, and some left halfway. And Li Zhen went up with just a sentence, and everyone began to take notes.

Those teachers also wanted to take out pen and paper to record, but they couldn't save face. Thinking that I am also a teacher, I said that I would be an auditor, but isn't it a bit ...... to take notes after listening to this audit? Inappropriate?

Li Zhen tapped the table with a triangle board and said, "What is fluid mechanics?" Fluid mechanics is the study of the stationary state and motion state of the fluid itself, as well as the interaction and flow law between the fluid and the solid boundary wall when there is relative motion under the action of various forces. ”

The person from the Physics Institute gasped and hurriedly recorded this tongue-twisting sentence in his notebook.

Li Zhen said again: "Let me give you a simple example......

Lin Xiufeng suddenly interrupted and said weakly: "I didn't hear it clearly just now, can you repeat it......"

Li Zhen didn't even look at him, and continued: "For example, we manage the river. Divert the flood water to other places and dredge it. This is within the scope of fluid mechanics. For example, a water pipe through which liquid flows, this is also within the scope of fluid mechanics. And these are relatively simple examples. ”

Lin Xiufeng lowered his head in embarrassment, Li Zhen didn't bird him at all. He has not yet been able to adapt to this high-intensity teaching environment, and he has been able to cultivate high-end training in a targeted manner, rather than casting a wide net. Li Zhen never repeats anything.

This is also a mode of teaching. When you like to learn and want to learn, the lecturer will only talk about the important points again. You will be in the full name of his lecture, mental strength, concentration and concentration. This kind of self-concentration is far more effective than repeating the explanation to you.

And this is the reason why everyone is crazy about taking notes, if you don't take notes, you won't be able to remember what he said after listening. It's too fast. After taking notes, everyone gathered around to discuss, discuss with each other, and get what each other needed.

When Lin Xiufeng was embarrassed, a young teacher took out his notebook and began to take notes seriously.

Some people took the lead, and the other teachers also took out their pens and papers. My hands were sore, and I was writing and taking notes quickly.

A wry smile flashed in Lin Xiufeng's eyes, and he also took out his notebook. And he was obviously sitting upright on a stool, and it was not easy to write when he was taking notes quickly. And the table is not enough.

Lin Xiufeng could only grit his teeth, simply lay on the ground, and listened to the lecture in a crawling mode.

After a while, all the teachers sat or lie on their stomachs in the positions they felt most comfortable with, or stood against the wall.

Lin Xiufeng was stunned, he finally understood why the Kyushu Academy of Sciences felt a miasma of smoke and did not look like a student. Because...... Li Zhen's lecture speed is extremely fast, if you don't find a way that is comfortable for you, there is no way at all.

PS: Recommend a friend's book "The First Immortal in the Human World": Swallow a golden pill in your stomach, and from then on my life will be up to me.

After a good night's sleep, you will become an immortal, what should you do in the future?

Teasing and teasing mortals, tossing and tossing immortals.

I am in the human world, but I am known as the first immortal of the Three Realms.

Wait, that's who, it's you! Say that I am the one who is the first scourge in the Three Realms, don't run, you have the ability to leave an address, I will go to your house tomorrow!

Don't worry, I promise with Xiange that I will never take a stitch from your family.
