I’ve already told you that the book is finished, and you’re still turning down the pages?

Under the rising moon, Rolf anxiously ran through the birch forest after nightfall.

In order to maintain balance, Suifengzhigui's pair of "J"-shaped elastic steel prosthetics have a very large contact area. Walking on flat ground always has a strange feeling. However, unexpectedly, the wide contact area makes him feel uncomfortable.

It was easier to move forward in the snow, especially when he controlled the wind, it was like walking on flat ground on the snow.

But Rolf had never had any experience tracking in the snow, and he had never lived in the north where the snow never melts - the central area of ​​​​the stars can only see seasonal sporadic snow. In the long and narrow Camus Alliance, the southeast

The five city-states were even dryer and warmer - this brought great trouble to his tracking, even though he was the first one to notice something strange about Serena's carriage and immediately pursued it.

The ability to control the wind allows Rolf to move with the wind like a fish in water in the narrow and crowded Hongfang Street, and his speed is no less impressive in the dense birch forest.

But he must find the boy.

The boy who gave the ghost of the wind new life.

Rolf walked through a forest and saw a flat piece of snow ahead.

His eyes suddenly froze!

The ghost with the wind was shaken and fell on the snow.

Under the moonlight, a charming woman wrapped in a cloak gently relaxed her hands.

A seven or eight-year-old boy with his hands tied behind his back slipped from her fingers without any reaction and fell on the snow like a murdered prey.

like a statue.

The alluring and charming woman turned around slightly, licked her tongue at Rolf, and showed a strange smile.

No.

Rolf fell to his knees on the snow in disbelief, and stretched out his trembling hands towards the boy with his eyes closed.

No breathing.

There is no heartbeat.

No pulse.

No.

That boy.

That grown-up boy.

The boy who gave himself a choice.

The boy who saved himself from the abyss of despair.

The amazing boy who taught him literacy, spelling, and sign language communication.

died.

No.

Rolf raised his head, half of his face hidden behind a silver mask, his expression indistinguishable.

"What's wrong?" Serena Corleone tilted her head and winked charmingly: "Oh, are you here to see little Thales?"

Rolf clenched his fists and slowly stood up, staring at the enchanting woman with resentment and anger in his eyes.

"Sorry, he fell asleep." Serena giggled:

"Come find him again in the next life."

Suddenly a strong wind blew on the flat ground,

Serena's expression changed!

The wind is getting stronger and stronger.

The snowflakes were blowing around Rolf, blowing all over his clothes.

The ghost with the wind stared at Serena.

He didn't know how strong the woman in front of him was.

But he will do his best to make the other party pay the price.

In this way, I owe that boy a debt.

Just pay it off.

But just the next moment, Rolf was shocked to discover:

He was stiff all over.

Can't move anymore.

what happened?

Is it...he rolled his eyes...this woman?

Serena laughed happily, her eyes never leaving Rolf, maintaining the pressure of the 'pause gaze'.

"Children these days," she pouted and shook her head as if in distress, nodded the side of her eyes, looked at Rolf who was frozen in place, and said:

"You don't have to use your brain to fight?"

————————

Too dark.

So dark.

Can't feel the time.

There is no space either.

Why did it suddenly light up?

It's so bright, it's so dazzling.

These are...memories?

So many memories.

Familiar or unfamiliar scenes flashed rapidly before his eyes.

Chaos.

In the end, only messy sounds remained:

[The central limit theorem provides sufficient basis for our random sampling... Don't get distracted! Learn these well, and at least you can go to the market research departments of various companies after graduation...]

What's this?

["Qi Ren, if you were in a different world waiting to be saved, would you become stronger, farm, advance in technology, compete for hegemony... would you want to change it?" "Forget it, social changes are always inevitable.

Elusive...unless I am the God of Creation..." "Okay, conclusion: there is no point in asking you this question." "What's the matter with your eyes full of contempt?"]

Such a familiar voice...

[Class issues are often combined with inequality, education, income, capital, these are common terms... Blau and Duncan, remember these two scholars, they will be your nightmare in the next two years... In our

In that era, if you didn’t know how to use log-linear models, don’t even think about doing social class analysis...]

It’s so confusing...why these combinations have no logic...

["Why are you so confused! Just one sentence, should we be together...why are you frowning!"]

Why does everything seem familiar, yet there seems to be a layer of fog...

[The key to the logistic regression model lies in this probability function, and the probit model is actually the same as it... If you only understand general linear regression but not logistic regression, don't say you have learned the regression model... nothing else

The reason is, I just think it’s embarrassing...]

Where am I……

[Everyone classifies him as one of the three great patriarchs, but compared to Weber's extensive quotations and scientific arguments, his kind of philosophical meditation that he came up with while sitting on a chair is classified as... Some radical scholars, including me personally, think

,This is simply an insult to our discipline...]

What is this... But, it’s such a familiar name...

[The one-mode social network can be represented by a symmetric matrix, while the two-mode is more complicated... Look at your stupid looks, haven't you ever studied linear algebra... Why haven't you studied advanced mathematics?

Think you have the ability to learn this subject well? Fart!]

Wait, I know what these are...I, I have studied, even written, taught...

["I don't know what the use of working so hard at home and reading so many books for you is, but our old Wu family always has an idea: knowledge may not be useful, but it must be priceless..."]

Who's talking...what the hell are these!

[For example, teachers, school location, class nature, parents’ income, the impact of different factors on student performance always play a role at different levels, some at the individual level, some at the class level, some at the school level, etc.

To distinguish the effects of different levels and simply assume that they are effective in the same dimension, the conclusion of "which student performance is most affected" is unconvincing... Therefore, hierarchical linear models are often used in education to overcome this point.

This principle also applies to our research...]
