June is our farewell song

Chapter 134 Understanding and Not Understanding
The sun was setting, and there was a faint fragrance of green grass in the air. Liu Qingsi was clearing up the sundries on the counter at the door, when she suddenly saw a book pressed under the kettle. When she picked it up, it turned out to be "The Shining".

"This...who put it here?"

"Ah, sorry, it's me."

Gu Yuan raised his hand, and Qing Si threw the book to him.

"Why do you keep a copy of The Shining under the kettle?"

"The more I looked at it last time, the more scared I became, so..." Gu Yuan pointed at the red kettle, "I think the bright red color and heavy objects should be able to calm down the anger a little bit?"

"Put the book under the kettle and you'll be safe?"

"Well... at least it will have some effect?" Gu Yuan said holding the "The Shining", "Every time I read this horror novel, I must make sure that there must be some heavy objects at hand, which can be used to... Squeeze it."

"Isn't it the first time you've seen it?"

"Yeah, don't you often read a book over and over again? Don't you just open it after reading it?"

"That's true. I've read "Wuthering Heights" many times, but...those are classics." Qing Si pressed the heating button of the kettle, "What's so good about "The Shining"? Haven't you read such a book? Is it enough once?"

"You should ask, what's not good about "The Shining"." Gu Yuan leaned on the back of the chair, watching her walking up and down in the activity room, "and the answer is yes, 'no', you know ?This is the scariest book ever, not only does it have scary moments like other horror novels, but it also puts the reader in a trance-like state where you might suddenly feel like someone or something is in your In the room, it’s as if they are right beside you. Regardless of the connotation, just from the perception, it’s definitely more than a dozen streets away from those ‘masterpieces’.”

"I don't believe it." When it comes to literature, Qing Si is always extremely firm.

"Well... how about this? Anyway, I haven't watched "Wuthering Heights", let's make an exchange. There are three days until the art festival. In these three days, I finished watching "Wuthering Heights", and you see After finishing The Shining, let’s discuss whether it’s the classics that are more readable or the popular novels, what do you think?”

Because it was a horror novel, Qing Si hesitated for a while, but in the end her strange competitive spirit prevailed.

"Deal." She said, and then took the tattered copy of "The Shining" from Gu Yuan, "The second row from the top to the bottom, the third from the right hand, go get it Well, Wuthering Heights."

"Okay, okay, don't rush, don't rush." ​​Gu Yuan raised his hands and walked towards the bookshelf. Halfway there, he turned around and said, "This is an agreement. Since I agreed, I must read it. If you give up halfway, yes will be despised by all."

"Oh, stop looking down on me."

Liu Qingsi straightened her waist, raised her head, her face was full of confidence.

At noon the next day, the sun was shining brightly.

Qi Yu sat on the seat by the window, holding a half-eaten piece of bread in his hand.The bread was terrible, dry and salty, but she had to make do with it because there was no time to eat.She had a physics book spread out on her left, and looked up every time she took a bite of bread.Although she told herself at the beginning of every semester since she entered school: "We must put our efforts in the usual way, and we can't cram our feet on the spur of the moment."

But the fact is always - until a few days before the exam, there are still quite a few pages that have not even been turned.

The prosperous sunlight shines through the window and spreads on the table.The tiny suspended matter that only appeared in the sun, floated up against the sun without any weight, climbed onto her forehead, and mingled with the fine sweat.

How warm can the sun be in December, but the sweat is coming out one after another.Those cumbersome equations, like wriggling bugs, refused to stay in her mind honestly—well, Bernoulli's equation, the pressure of a fluid plus the product of density, acceleration and height, and... What else is there?

Anxiously, Qi Yu stuffed unpalatable bread into his throat, and he had to remember the physics equations that were annoying to the point of death.Getting more and more anxious, sweating more and more, I simply pushed my hand-I quit!
However, after a few seconds, I pitifully grabbed the books and bread back. After the art festival, there was a monthly exam, and there were two days before the art festival, that is to say, there were two days before the exam plus a weekend.If you give up reviewing now, then when you go to the examination room next Monday, you can only hold the determination to die.

Why are those two idiots, Gu Yuan and Feng Ziqiu, able to memorize these things so easily?Why do they still say how "beautiful" these equations are when they are ugly?Is there anything more depressing in this world than these?
Then Qi Yu thought of mathematics, and thought of the bunch of unexplained theorems in number theory, and she felt that she was going to be depressed soon.

If Gu Yuan could hear Qi Yu's voice, he would definitely refute it.First of all, memorizing so many complex formulas is not an easy task, at least for him.Secondly, he has always wanted to know why Qi Yu can always calmly find the correct answer from the pile of plausible options when doing English reading.You know, every time Gu Yuan asks her with a wrong question, when he sees her shake her head and then drop a light "intuition", he really wants to punch her bright forehead .

But he couldn't hear, and his attention was completely absorbed by the "Wuthering Heights" in his hand.Heathcliff's revenge and love stories made him addicted to it and he couldn't extricate himself. The masterpiece really has its own charm, which is a different reading experience from popular novels.

Looking past Gu Yuan, Qi Yu looked out of the window, the deciduous trees on both sides of Central Avenue, the leaves all over his body were washed away by the winter wind.The sky is no longer cloudy and cloudy like the stinky face of an old woman, but clean and cold, like the flaxen eyes of a half-breed.

"Look at me for what?"

"Who's watching you, narcissist."

"Then what are you looking at?"

"I'm tired of studying, look at the sky, why, can't you look far away?"

"Okay, okay, then you can continue."

Gu Yuan yawned as he spoke, then continued to look down at his book.

"Tell me about fluid pressure and flow velocity."

"No talk, no time."

"Are you going to talk?"

"Don't talk."

Qi Yu stretched out his left hand to Gu Yuan's waist.

"Ahhhhhhhhhhhhhhhhhhhhhhhhhhhh!!"

Then there was Gu Yuan's decibel howling.

"Shh - someone else is resting."

"I'm already very quiet, violent maniac. Okay, let's take a look."

"No hurry, hey, what are you looking at?"

"Wuthering Heights."

"So devoted?"

"Because it's so beautiful. Do you know that Catherine actually agreed to Linden's marriage proposal? It's unbelievable. Heathcliff and her are childhood sweethearts, and they have experienced so much together..."

"Yeah, I know I know." Qi Yu nodded, "It's indeed a pity, but is it so unbelievable? Childhood sweethearts, childhood sweethearts, do they have to be together?"

"It's not that it's certain, but... how should I put it, the emotional foundation is relatively deep."

"That's not the case. You should think about it this way. Since we've known each other for so many years and even grew up together, but neither of them became boyfriend and girlfriend, it means that maybe the two of you are not suitable for this path at all."

"Well... that sounds like a possibility too, so Catherine and Heathcliff are like that?"

"No, no, it's not the same, they are not like this." Qi Yu denied it, "You will know after reading it."

"Ok."

"and many more."

"what?"

"I haven't read the title yet."

"Oh, I see... Well, the first thing to be clear is the relationship between fluid pressure and flow velocity. The higher the flow velocity, the lower the pressure. Is there a problem with this?"

Qi Yu shook his head and nodded again.

"...Do you know or don't you know?"

"I know the theorem, but I don't know why."

"Okay, then I will tell you about the Bernoulli equation, which is the formula that specifically describes the relationship between pressure and flow velocity in a fluid. We know that the pressure P of a liquid is equal to the density of the liquid, the distance from the horizontal plane, and the acceleration of gravity g Product. Using this as a starting point, imagine a long and thin pipe in which an ideal liquid flows from left to right. Taking two different points A1 and A2, we obtain two cross-sections S1 and S2, And a piece of fluid. Next..."

"Wait, wait, speak slowly."

"It's already very slow. Is there anything you don't understand?"

"Too much.",

"for example?"

"What is fluid?"

"..."

Gu Yuan took a deep breath and let it out quickly.

"I can understand the concept of non-Newtonian fluids without knowing it. Is it too much to do fluid pressure without knowing fluids?"

"I don't want to be like this either! Don't talk about other concepts..."

"Hey, in short, you should memorize and understand the basic concepts first, and then try to solve the questions."

"Exhausting etiquette, Sister Li... If I can understand myself, can I still use you?"

"... There is no way to do this. If you don't even know the basic information, then understanding is empty talk."

As if her heart had been touched suddenly, Qi Yu's slightly emptied pupils were clearly filled with the noon sun, and she suddenly realized something.

Lack of information leads to incomprehension.

Not just physics, but other aspects as well.

Out of the corner of his eye, he saw Feng Ziqiu concentrating on the exercise in front of him, and the outline under the broken hair was covered with a thin layer of shadow.

A certain powerful force began to break through all the lines of defense and restraints, spreading crazily around.

"Hey, are you listening? Good words are just a few words away. If you don't listen to the old man's words, you will suffer."

"Go, go, you don't look good anymore."

Back to reality, Qi Yu felt as if he suddenly emerged from the bottom of the water.

"It was originally..."

While flipping through "Wuthering Heights", Gu Yuan grimaced, his eyebrows were raised high, and his chin was stretched out.
