Chapter 32 - The classroom is full of sunlight, and the creeper outside the window is blown by the wind.Shen Dayye looked back, wondering who that Garrett.P was.Generally speaking, after throwing the paper airplane, the other party will be curious to see the reaction of the person who was thrown and will be very nervous, but in fact, Shen Dayye didn't notice that anyone was looking at him, most of them were listening to Chen Xiaozhi's class.Shen Dayye looked for a while and then gave up.-- A note of accosting.For Shen Dayye, this note is actually very common, after all, he receives one or two every year.Shen Dayye was born delicate and soft, and his eyebrows and eyes were soft when he smiled, like before the stars fell on the flowers.The girl's beauty can be seen in junior high school - and girls who receive love letters in junior high school often don't lack people to talk to when they go to college.Shen Dayye couldn't even remember the faces of the people who passed her notes.But she remembers that she rejected everyone.At that time, there was a freshman boy from Yuanpei Academy, and when he handed a note to his senior sister, he even put a purple swallow flower in her book.-- Starting a relationship with someone of the opposite sex is a very mysterious thing, and it is very emotional.No matter how good the other party is, if you don't call, it's useless for the other party to do anything.Twenty-five-year-old Shen Dayye looked at the note.What really attracted her to that note was that it quoted a sentence from Pablo?
Neruda's poem.- Pablo, who is still young?
Neruda wrote to his lover the fourteenth of the famous "Twenty Love Poems".Shen Dayye looked up at Chen Xiaozhi who was in class.The sun was shining on the person who made her feel strange.At the age of twenty-five, he smoked again than before, and his handsome face faded from the childishness she once knew and became angular - he stood on the podium and could be called radiant.Not everyone can give such a lecture and do his kind of research, and not everyone can have such a clear logical and terrifying knowledge reserve, innovation ability and thinking.Chen Xiaozhi is already very unfamiliar.Shen Dayye thought in a daze.However, at the age of twenty-five, every bit of light on his body could see the traces of the young Chen Xiaozhi.The glorious boy is still here, but he has grown up.-- Shen Dayye couldn't even speak, but this young professor seemed to be born for the celestial bodies and the universe, and for the reason of all things.In the next second, in the shroud of golden sunlight and flower shadows, Professor Chen drew a huge fan on the blackboard to represent the space of the stellar structure, threw the chalk, and asked the students below in a standard American and Western accent: "So, if you want to know the structure of the star, it is up to the scholars to build a model and make the next inference."
It's obviously impossible to drill a hole in a star that is tens of thousands of degrees hot and see what it looks like inside. ”"We all know that the heat of a cosmic star of several thousand degrees can make the human body vaporize instantly."
Chen Xiaozhi said casually: "--There are not even bones left. ”"And our astrophysicists' observations are themselves burning the budget, so we must have sufficient theoretical support before making actual observations.That is, our assumptions and inferences must be satisfactory and unassailable. ”Chen Xiaozhi added: "Therefore, one of the important research methods of astrophysics is also different from other applied disciplines - we first need to simplify the hypothesis, then list the basic equations, find out the relevant boundary conditions, and finally conduct actual observations to test our hypothesis." ”Chen Xiaozhi asked: "Let me ask you the first step, how do you simplify the assumptions. ”"Suppose I," the young Professor Chen patted the chalk ash on his finger and looked sharply at the students below, "wondering about the structure of a star......
So first, what kind of model should I build?
”A black female student below didn't know what to say, the whole class was laughing, and even Chen Xiaozhi bent his eyebrows in the sun.Shen Dayye drank bitter coffee with a sad face, and found that Chen Xiaozhi actually had a kind of teacher's kindness."
Totally wrong."
Professor Chen said kindly: "And I found that your knowledge of fluid mechanics is so weak that you don't even consider this factor. ”The black female student spoke with an Orleans accent and a pair of black and white eyes, looked at Chen Xiaozhi and said, "I haven't studied fluid mechanics yet." ”Chen Xiaozhi smiled: "Then you'd better come back after studying, otherwise you will encounter a lot of difficulties in taking this course - I'll find someone to answer this question."
How will you build the model?
”Shen Dayye picked up the triple espresso given by Chen Xiaozhi, pinched the cup sleeve and took a small sip, looking at him in a daze.Isn't he able to smile at other girls, Shen Dayye suddenly uncontrollably appeared above his head, and a small bubble with small ideas appeared.Then, like a broken window, a series of bubble porphyries popped up: how could he be so fierce to me if he could smile at a student he didn't know......
Even if it's an ex-girlfriend, it's a bit too fierce, it's okay to be a dead person......
The string of thought bubbles one after another, Shen Dayye felt a little aggrieved.In the next second, Chen Xiaozhi, who was insulted by Shen Dayye's heart, stepped off the podium and slapped Shen Dayye's table hard.
@无限好文, it's all in Jinjiang Literature City, "There are only you in the first row," Professor Chen paired Shen Dayye, and the Meixi accent instantly became extremely different: "This young lady in the C position, tell me, how do you build a model?"
”"......"
Shen Dayye knew as soon as she heard that Chen Xiaozhi was here to give her a horse.He also patted the coffee cup, a little grumpy, and motioned for her to answer quickly.The difference in treatment is too great!
Shen Dayye felt angry and sad at the thought of the treatment of the other students—she looked at the fan-shaped and blackboard-filled board, and thought to herself, what the is this?
You look down on me so much?"
The premise of these inferences," Shen Dayye narrowed his eyes, "it should be that the star has a fluid sphere of radiation transfer inside under the action of its own gravity and internal pressure, which satisfies the conditions of no magnetic field and non-relativistic symmetry with the sphere." ”This line of thinking should be correct, Shen Dayye thought.Chen Xiaozhi: "Basically correct, what else?"
”"The theoretical model should be an isolated planetary system," the sun shone on Shen Dayye's arm, and she sat down in her chair and thought for a moment, "only by the action of self-gravity and internal pressure, and to satisfy the equilibrium of hydrostatics." ”Chen Xiaozhi narrowed his eyes: "Define the meaning of spherical symmetry." ”"......"
Shen Dayye thought to himself, can't you ask others this little question......
Then she said: "Concentric spheroids, the substances of a single sphere are homogeneous. ”Prof.
Chan: "What equations do you use?"
”“…… Mass distribution equations, hydrostatic equilibrium equations, energy balance equations, energy flow equations. ”Shen Dayye recalled the English name of the last equation, which she hadn't touched for almost five years, so her memory was a little rusty - and then Shen Dayye said the last noun firmly: "- almost all equations of matter."
There shouldn't be any omissions. ”When Shen Dayye said the name of the last equation, she raised her head slightly and looked at Chen Xiaozhi who was standing in front of her.There was a strong wind outside the window, and she was so fluent that a student shouted Bravo from below.Shen Dayye thought to himself that I probably wouldn't be praised, and then the next second, Chen Xiaozhi patted her table, with a hint of looking for something, and said, "That's a good answer, but don't look at your teacher like that."
You look like you're going to eat me. ”Shen Daye: "............"
Shen Dayye looked at the face of Professor Chen, which she was familiar with, and there was only one inexplicable and abstract sentence left in her mind - that sentence was repeated by one of her junior sisters in the office while smashing the table after meeting a scumbag in online dating: 'I will penetrate your mother. ’- You're just trying to get something out of me!
- At about three o'clock in the afternoon, the sun in California sank a little more, the sky was blue, and the wind blew through the gladiolus outside the window.On the podium, Chen Xiaozhi said to the students below: "Everyone rest for a while, come back and continue." ”The lecture hall instantly became more noisy than before, some girls in plaid shirts went to the toilet outside, and one or two people went up to ask Chen Xiaozhi questions, and he leaned on the podium to communicate with those students casually.Shen Dayye sat alone on the stool, taking small sips of bitter coffee and flipping through the red-skinned textbook.Chen Xiaozhi did well in class, and she also took a lot of notes.- But why did he treat himself so badly?
Shen Tianye couldn't figure out how to think about it, so he sat at the table a little uncomfortably and sighed, and when he raised his head, he saw the adult Chen Xiaozhi smiling and holding a pen and clicking a few times on a student's notebook.The sun is gilded on their bodies, and there is an indescribable romance and warmth.Shen Dayye sat dumbfounded, remembering the way he trained himself, and after a while, he felt a kind of despair that couldn't find a way out, and he fell into the book with a bang.…… It's not her world.-- Shen Dayye is already twenty-five years old.This is her eighth year in college.-- Freshmen are still very different from sophomores, and many people can tell at a glance the difference between a college student who has been in school for one year and a college student who has been in school for two years.Four years is enough, but what about eight years?
Even if Shen Dayye came to take undergraduate courses, he no longer had the vitality of an undergraduate.She had no friends or support in this strange place, like a dead tree in the wilderness.Although Chen Xiaozhi didn't scold her seriously, it is an indisputable fact that she is only a passer-by in this course and even this university - Shen Dayye can't enjoy a colorful life, has no parties and no acquaintances, and is always out of step with the surrounding environment.Pale and transparent like a petal floating in the water, the wave will sink to the bottom of the water and never be seen again.Just like the years she had been.-- It was a kind of loneliness without belonging.Shen Dayye was lying in the book, and she heard the wind whirring outside the window, like a whole autumn that was about to blow, and she also heard Chen Xiaozhi's voice coming intermittently above.Twenty-five-year-old Shen Dayye closed his eyes and lay on his stomach in the book, trying to squint a little.However, in the next second, there was a 'bang', and a heavy schoolbag slammed into Shen Dayye's side!
Shen Tianye was startled and raised her head—there was a young Hispanic young man standing in front of her.The young man was quite tall, with his bag belt still in his hand, slightly long dark brown curls, and dark black eyes.He had an indescribable, poet-like romantic air on him, wearing a simple hoodie and jeans, and smiled at Shen Dayye: "Hi, I'm Garrett. ”Shen Dayye was stunned, and subconsciously removed his coat to make room for the young man.Then in the bright sunshine, the Hispanic young man asked her in awkward, but somewhat gentlemanly Chinese: "Miss, can I sit next to you?"
”-…… Shen Tianye burst out laughing and said in English, "You can speak English with me." ”The golden light reflected the flower branches outside the window, gladiolus confided flower buds, Shen Dayye moved a place for him, but this young man named Garrett did not sit beside her, but left a comfortable distance for Shen Dayye and vacated a place with her."
Garrett Perrotta," Garrett stretched out a hand and smiled at Shen Dayye, "You can call me by my name directly." ”Shen Dayye smiled with crooked eyebrows, shook Garrett's hand cooperatively, and said, "AprilShen." ”"I was very impressed with your performance in class," Garrett said with a smile, "and your name is nice -- April, it's spring." ”Shen Dayye felt that this person was very interesting, and said in a friendly manner: "-This is the name my father gave me, my Chinese name is not called this, but it is not too much." ”Garrett asked with interest, "Do you name your daughter April?"
”"Yes, because I was born in the spring," Shen Dayye said with a smile, "And my mother has a poem that I like very much, called "You are the April Day of the World", and my English name is April." ”@无限好文, Garrett said with a smile: "It's a very beautiful name." ”Shen Dayye said politely, "Thank you." ”"Will you come back to the next class?"
Garrett asked mildly and a little romantically, "Or are you only here this time?"
”Shen Dayye glanced at Chen Xiaozhi.This said that he was going to eat his sassy was leaning on the podium, leaning on the podium, giving a lecture to the students like a dog-Shen Dayye felt a little autistic.Shen Dayye said to him, "......
I should be here this semester. ”"The lecturer is......
It's my mentor. ”Shen Dayye sighed: "It was he who asked me to come and listen to his class, so I should be listening to the end of the term, so to answer your question, I am still there in the next class." ”Garrett laughed, "Then he's a little bad for you." ”Shen Dayye thought for a while and summed it up succinctly: "-- This is the reason left over from history. ”"I forgot to introduce, I'm from law school."
Garrett said gently, "Because this course is interesting and recommended by a friend, I chose it at the beginning of the semester."
I just noticed, you answer so smoothly and so charmingly. ”Shen Dayye was praised a little, his ears were a little red, and he whispered: "I'm almost forgotten all about it......"
"Has anyone said that," Garrett smiled and spread out his notebook, his charming black eyes looked at Shen Dayye and said, "-Your eyes are beautiful?"
Well?
”"......"
Shen Dayye said very honestly, "-Yes." ”"That's a lot of people."
Finally realized that I was being teased, and the polytechnic girl said rigorously: "But to be honest, I don't know where it looks good." ”Garrett: "Like a black pine forest......

Shen Dayye rubbed his forehead and asked in a low voice: "Don't pine forest, don't pine forest, I have a question, are you from Italy?"
”Garrett: "yes, what's wrong?"
”@无限好文, all in Jinjiang Literature City Shen Dayye: "......
It's nothing. ”-…… Three p.m., Circular Lecture Hall.Chen Xiaozhi lowered his head and explained to a student the method of measuring the temperature of the sun in a way that was as simple as possible.Obviously, the temperature of the sun cannot be measured by any thermometer, nor can it be measured by infrared - its original measurement method was proposed by a 19th century scientist Eddington, the theoretical basis is that the sun transfers heat through radiation, and it is also through the establishment of a model, using the ideal gas heat balance as a model, to calculate the initial temperature of the sun in the ideal model: 39 million degrees Celsius.Astrophysics, especially the theoretical part, is extremely model-dependent.There are not only physics students in his class, but also many people from other colleges who have come to join in the fun, and now there is also a 'doctor' he brought with him - Shen Dayye.Chen Xiaozhi thought of this name and unconsciously grinded his teeth.- 'Shen Dayye. ’The name almost made his eyes red with hatred.The girl represented by these three words is thousands of miles away, but she does not exist beside him all the time, like a ghost that winter.But now she's sitting in this classroom."
Okay," Chen Xiaozhi said: "The class has to start again...... he pinched a piece of chalk and raised his head.
