Lin Zhaoxi found that the three openings were more difficult than expected.
One side is Olympiad training, the other side is advanced mathematics, and at the same time, she also has to explore the problems in the field of machine learning.
This is not to say that she can't cope with these things, but there are only 24 hours in a day, and she needs to study the intersection of computer and mathematics while completing the daily test questions.
And because the latter involves too much knowledge related to university mathematics, in order to understand the book, she is more eager to learn linear algebra and probability theory mathematical statistics more solidly.
These contents basically rely on self-study. Although Lao Lin is not around, fortunately Pei Zhi is still there, and life can be passed a little bit.
At the end of June, it was already very, very hot.
But at 5 o'clock in the morning, when the sky just dawned, the temperature was still relatively fresh and comfortable.
Lin Zhaoxi got up on tiptoe, packed her schoolbag, and was ready to go out.
The curtains in the dormitory were drawn tightly, and her movements were very light, but Yin Xiaolin, who was lying on the upper bunk, still woke up.
Yin Xiaolin turned over impatiently, as if she was holding back something.
After getting along for so many days, Lin Zhaoxi knew that this senior was really suffering from a nervous breakdown. She hurriedly picked up her schoolbag and went out quickly without buttoning her jacket.
Many people have said that the brain is the clearest in the morning, and the efficiency of study and work is the highest, provided that you can get up.
Lin Zhaoxi ran all the way to the cafeteria door with her schoolbag on her back, counting it as an early exercise.
There are only a few people in the campus, and even egrets and birds dare to come out to hang out.
Panting for breath, she sat on the steps, opened the textbook, and read it by herself.
After reading the book for a while, she took out a pen and paper, closed the book, and began to deduce and prove it. College mathematics understanding is more important. If you can't understand it, you should finish the questions and then understand. This sentence is what Lao Lin said.
After 6 o'clock, the cafeteria opens.
The master who opened the door knew her well, and when he saw her, he joked: "Others secretly go to the small pond to read, but you are the only one who opens the door of the cafeteria every day."
Lin Zhaoxi also laughed: "Master Ma, I'm really hungry!"
Jumping up and patting her butt, Lin Zhaoxi ran into the cafeteria and bought two steamed buns and a cup of soy milk. No matter how tight the time is, eating must never be relaxed.
Generally speaking, at 7:30 in the morning, Pei Zhi would come to the cafeteria to have breakfast with her.
This reflects Brother Pei's excellent work and rest tradition. No matter what timetable other people around him use, he always has his own set of standards. He gets up at seven and shows up at half past seven.
Generally speaking, as a good dog who needs Brother Pei's guidance, Lin Zhaoxi will buy Pei Zhi's breakfast and wait for him at around 7:20 to honor Brother Pei.
After all, Lao Lin is not here, and only Pei Zhiben can explain college mathematics to her.
The class officially started at 8:30. Lu Zhihao and Chen Chengcheng, as young people who needed sleep, often ran into the classroom with the bell ringing.
Their meal cards were simply placed with her after dinner every day. In the morning, she swiped them for breakfast, and then put the meal cards in the breakfast bag and returned them to them.
Because we are all young people, we like to sleep in rather than have breakfast.
So in the first class in the morning, the classroom will be filled with the sounds of unpacking and secretly eating breakfast.
The smell of steamed buns wafted everywhere, and even Zhang Shuping had to give up the first class for them to do a quiz, and instead gave lectures and gave them time to eat.
But when most people finished their breakfast, Zhang Shuping put down the chalk, and the test papers were handed out like flakes. They had to do the morning questions in pain.
The sweltering heat and the heat wave hit again, and the sun was frighteningly hot at noon.
Lin Zhaoxi was too lazy to go to the cafeteria to eat at this time, she would buy lunch in the morning, have a couple of snacks at noon, and then go to the computer room to use the computer.
Although matlab bars are more popular in this era, Lin Zhaoxi decided to learn python first.
She shamelessly registered in the library of Sanwei University and wanted the book on numerical methods engineering with python. The library really bought this book. As the first person to borrow a new book, she spread it out and read it non-stop.
But this is all in English.
Before she finished reading a page, she came across a dozen unfamiliar words. Looking at the book, the joy of borrowing the book in her heart was extinguished a lot.
Clicking on the browser, she began to look up the words one by one, and then continued to look down, but the progress was still very slow.
It would be great if I could go back, the thought popped up again.
The wind from the cold air conditioner couldn't resist the scorching sun outside the window, Lin Zhaoxi got hotter and hotter, sweat ran down her cheeks and dripped on the pages of the book, she hurried to wipe it off.
The moment her fingertip touched a drop of sweat, she turned it slightly, and she drew a line of formula on the paper.
e=mc^2
The main computer was running rustlingly, and the air conditioner was blowing out weak air. Lin Zhaoxi raised her head. She was still in the library of the old campus of Sanwei University, and nothing had happened.
What fool are you doing
Lin Zhaoxi rubbed her face, obviously, she should cherish the extra study time she had finally gained, and use it like ten minutes instead of trying to make up for the shortcomings with cheating fingers.
And what if, after she went back to the past, she suddenly couldn't come back
—
The time is tight, with more than 180 days in half a year, she has to face mountain-high courses and insurmountable knowledge barriers, and every minute is very precious.
Sometimes Lu Zhihao and Pei Zhi would come online with her, sometimes not.
Comrade Lu Zhihao is more gossip, he will ask her what book she is reading, why it is all in English, and what is she trying to do recently
But Pei Zhi never asked these questions.
Lin Zhaoxi thinks about it too, and she never asks Pei Zhi, "What are you learning?", "What are you thinking about with those ghostly symbols you wrote, and so on.
They tacitly kept a certain distance.
—Everyone has their own secrets and needs their own space.
This was what Lin Zhaoxi thought at the time, and she regretted it very much later.
In fact, this is not the case.
—
The day Pei Zhi left the training team was said to be the hottest day in June.
The temperature in Yongchuan City hit a record high. When she went out for a run at 5 a.m., she felt the scorching heat of the rising sun.
As usual, at 7:30, Pei Zhi stepped into the cafeteria on time.
Lin Zhaoxi waved to him happily, and when she had set up the breakfast, she noticed that the boy was carrying a heavy schoolbag on his shoulder, with a bright yellow check mark on it, and it was stuffed bulging inside. It was from when Pei Zhi came. Luggage bag.
"Brother Pei?"
Lin Zhaoxi was stunned.
"What's the problem today?" Pei Zhi put down his backpack as usual, picked up the habit and opened the soy milk, and asked her this.
"Why do you have to bring such a big bag to class?" Lin Zhaoxi continued to ask.
"I am going home."
"Why!?" Lin Zhaoxi moved her hand and almost knocked over the milk on the table.
"There is something at home."
"What's the matter, you're not participating in the training camp?" Lin Zhaoxi became nervous.
"Um."
"Is it because of your mother?"
"Maybe."
"Why 'possible', what about mathematics, do you continue to study mathematics?"
Lin Zhaoxi couldn't restrain her voice, and the questions continued like a cannonball.
"It's a long story."
But Pei Zhi didn't answer her question at all, he just said so lightly.
Lin Zhaoxi knew that Pei Zhi's stay in this training team might be boring, but he has always stayed here very firmly, even when he was in elementary school, he was very firmly with them.
So when he suddenly said that he wanted to leave, it was like a thunderbolt to her.
Now I really want Pei Zhi to clarify "what is a long story", and I really want to say "I can wait here for you to finish".
But whether it's Pei Zhi's expression or his tone so far, it's very clear: I don't want to talk about this right now.
Lin Zhaoxi's heart gradually cooled down.
After finishing the senior high school entrance examination, Pei Zhi said something that seemed to be joking and slightly ambiguous at the school gate.
But now it is very likely that this ambiguity is just her misunderstanding.
When a boy and a girl get closer, the boy probably thinks that you are just friends, but the girl can't help but think that the other party likes her.
This kind of misunderstanding has caused many embarrassing situations. Lin Zhaoxi is very uncertain now.
There was a long, icy silence.
Although they used to sit together without saying a word for an entire afternoon, that kind of quietness was completely different from the current silence.
"What's the matter, can you tell me?"
"To be honest, it's hard for me to explain clearly."
Lin Zhaoxi worked hard: "If you are in Anning, you can ask Lao Lin for any questions, and when you know, you can tell me what you want to say!"
"Ok, I know."
Pei Zhi pulled over her exercise booklet: "I'll finish it for you."
His fingers were slender, and he watched her handwriting with clear eyes, interrupting the heart-pounding words she was about to say at the right time.
Lin Zhaoxi felt it clearly.
