In the confusion, Xu Chuan felt someone calling him. He wanted to open his eyes, but it was very difficult. The whole person seemed to have gone through a long journey, or had a long dream, and was very tired.
"What's wrong with you today? You're still sleeping after lunch break."
The voice in his ears came again, Xu Chuan opened his eyes suddenly, and the bright sunshine outside the window shone on the wooden desk.
In front of me is a huge blackboard with white chalk writing on it.
Next to him, a boy who looked about seventeen or eighteen years old was looking at him strangely.
Xu Chuan was stunned for a moment, and the memory suddenly appeared in his mind. He was stimulated by the weightless feeling of rapid falling and tightly grasped the desk in front of him. It was not until the falling feeling dissipated and the solid touch came from his feet that he calmed down a little.
Come down.
After taking a few deep breaths, Xu Chuan raised his head and looked around. In the noisy classroom, some familiar and unfamiliar faces emerged from his memory.
"This is Class 1201, the third year of high school?"
"Did I have a dream? Or did I travel through time and go back twenty years ago?"
"If it was a dream, how could those memories be so real?"
Looking at the familiar yet unfamiliar classroom, Xu Chuan was a little confused for a moment.
The memories of the future in my mind were extremely clear, and the scene of the plane crash was even more frighteningly real.
"What's wrong with you? Do you have a cold? Go to the infirmary?"
Hearing the voice, Xu Chuan raised his head, glanced at his former deskmate, and shook his head.
"I'm fine, I'm going for a walk."
...
Outside the teaching building, the playground with gray cement floor tiles was extremely flat. Xu Chuan was walking on it, and some scattered classmates were doing activities, which also brought him some memories buried deeply in his mind.
After finding a step and sitting down, Xu Chuan looked at the two iron trees that were blooming not far away, with a wry smile and bitterness at the corner of his mouth.
He didn't expect that he would come back like this.
You must know that there were not just him on that plane, there were officials who accompanied him back to the country, there were also people from that country, and even an important figure who was accompanying him on the trip.
In addition, there were nearly 300 ordinary passengers and crew members.
Coupled with the exchange of countries, I thought I could return home safely under such multiple guarantees, but I didn't expect that I still couldn't come back.
It is a pity that before he died in his previous life, he was only one step away from the motherland, but he had not yet entered the territory of the motherland.
...
After sitting quietly on the steps for a while and relaxing his mood, Xu Chuan stood up, patted the dust on his pants, and turned around to enter the classroom.
The familiar desk, the familiar textbooks, the familiar classmates, everything was exactly the same as the scene he remembered when he was seventeen years old.
"Am I really reborn?"
Xu Chuan touched the thick textbooks piled up with bookends on the table. His fingers felt the thickness and touch of the books. It was very real, and it also made him fascinated and confused. There was also a trace of fear, fearing that this was just a dream before the crash.
.
"Even if it's just a dream, please stay a little longer."
Xu Chuan raised his head and looked at the bright sunshine outside the window, with a bright and determined smile on his face.
...
"Ring ring ring ring..."
The shrill ringtone echoed throughout the campus.
In class 1201, a middle-aged man with a thermos cup and a thick test paper under his arm walked into the classroom. The originally noisy classroom quickly became quiet.
"The midterm is coming soon. Let's do a preliminary test in this class. The monitor will come and divide the test papers. Don't think about cheating. It doesn't make any sense."
A middle-aged man named Tang Gaoyuan is the physics teacher of Class 1201 and the head teacher of Class 1201.
Tang Gaoyuan looked at the students in the classroom solemnly, put the test paper in his hand on the table, and then added.
"Xu Chuan and Cao Weicai come with me first."
Xu Chuan stood up and walked out with another young man with thick eyes.
"Teacher Tang."
"Teacher Tang."
In the corridor, Tang Gaoyuan was sipping tea from a thermos cup. Xu Chuan and Cao Weicai greeted him respectfully and stood aside.
For Xu Chuan, Tang Gaoyuan was his enlightenment person in physics. He taught him physics from the first year of high school. It can be said that without him, he would not have been able to stand at the pinnacle of physics in future generations.
Seeing the two of them, Tang Gaoyuan smiled gently, completely different from the serious look on his face before in the classroom.
"This year's animal contest will start soon. I'll sign up for you. You should prepare yourself. Training will begin in a few days. I hope you can get better results this year than last year."
Normally, unless senior high school students are particularly outstanding and are confident enough to enter the national training team, they rarely participate in competitions such as the physical education competition.
Generally, the majority of students participating in competitions such as physics and mathematics competitions are sophomores in high school.
After all, most students still have to take the college entrance examination, and participating in competitions is very time-consuming and energy-consuming.
But it would be different if you could join the national training team. Every student who could join the training team and represent the country would have universities rushing to get him.
The two in front of me are Xu Chuan and Cao Weicai. They both joined the training team in their sophomore year of high school. It can be said that it was the most glorious year for Star City No. 1 Middle School in recent years.
"Business competition?"
Xu Chuan was slightly confused, and then realized it was IPHO. At the same time, the memory deep in his mind was revealed.
IPHO refers to the International Physics Olympiad. Participants must not be older than 20 years old on June 30 of the year of the competition.
It is held every year and is hosted by the member states that make up IPHO in turn.
This member state basically covers most of the countries in the 18 regions around the world.
It's almost like every country in the world sends its five most elite high school students, and then they fight on the physical battlefield to compete for the first place.
He participated in this competition as a sophomore in high school last year and as a freshman the year before. In his freshman year in high school, he barely made it to the provincial team and entered the national finals due to lack of knowledge. However, he was not able to compete for the country. Last year in his sophomore year, he successfully competed.
I joined the national team and entered the final world championships, but unfortunately I didn't win the gold medal.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! It is now late August, which is almost the time when the first round of IPHO selection begins in China. According to the historical development before rebirth, he will also participate in IPHO this year
, and successfully entered the national team to compete with students from other countries.
It's just a pity that although he successfully won the gold medal in next year's IPHO, he did not win the "absolute winner" and was two points behind the Korean player.
The so-called absolute winner is the contestant with the highest score in the physical competition. In addition to winning the gold medal, he will also receive a special award. This is also his regret.
But when talking about IPHO, Xu Chuan thought of another competition, the International Mathematics Olympiad (IMO).
The reason why he remembered this was because he remembered a piece of news he knew before he was reborn.
...
Rebirth brought Xu Chuan not only the various scientific research knowledge in his mind for the next twenty years, but also the general international trends in the future, as well as some other news.
It is now 2014, if there is no problem with some memory in his mind.
From unknown time in the past to 2017, the country opposite the west coast has increased its penetration into other countries, and various information activities have become stronger and more frequent than before.
And for this event, the country on the west coast adopted a brand new information security method to communicate and deliver information.
This information security communication method is based on a mathematical law. Only by finding this mathematical law can the information inside be deciphered.
But the key point is that the logic and functions in the mathematical rules used by each intelligence are different, and it takes a certain amount of time from intercepting the other party's intelligence to manually deciphering it.
Often it is within this period of time that the other party has completed the information transfer.
According to the information Xu Chuan knows, starting from next year, we will begin to seek help from mathematics students who have participated in IMO competitions. Of course, it is also possible to put these topics into the study scope of competition students.
He never looked at those math problems, because when he learned about it later, these things had already passed.
But if you think about it for a moment, you will know that those questions are definitely not something that ordinary high school students, college students or even graduate students can solve.
Anyone who can devise this set of mathematical laws and use them for national invasion is definitely not a vegetarian.
Although high school students who can reach the IMO finals and win medals are extremely talented in mathematics, in the face of this kind of thing, they will not be of much use.
So there is a high probability that it will be the latter.
But for Xu Chuan, this is an opportunity to be exposed to this matter. If he can show enough mathematical talent in the competition, then it is possible to participate in this matter.
