On January 11, 2007, China conducted an anti-satellite missile experiment. Foreign media reported on this one after another on the 18th. On the 23rd, the Chinese Foreign Ministry officially admitted the matter and emphasized: "In principle, China advocates the peaceful use of space, opposes the weaponization of space, and never participates in the space weapons competition."

Since then, many foreign media have conducted negative reports on the anti-satellite missile experiment, including some domestic media have published reports of similar tendencies. Many people at home and abroad who are paying attention to this matter have also discussed this.

Fang Chang'an heard the students' discussions about this matter in the classroom after morning self-study class on the 26th.

"Isn't the Cold War just an arms race... and it disintegrated later..."

“Didn’t the Ministry of Foreign Affairs say that it will not participate in the space weapons competition?”

"The anti-satellite missiles have been made. Who would believe you if you don't participate?"

At first, there were only a few people talking about it, mainly a few boys who were studying at the day, Huang Yuanwu, the one who Zhao Dalong came to the classroom to find fault and then quickly approached Fang Chang'an, but Fang Chang'an had no idea about his name, a boy named Cao Yunhua and Liu Feng, a total of four or five boys. Later, Su Xuan and a few girls also interjected a few words, and the scope of discussion quickly expanded.

"Even Russia seems to have said something against us..."

"More than just the United States, Britain, Japan and Canada, all these are said..."

"Then if we don't develop, what will happen if people beat us in the future?"

"Now it's globalization. We have all joined the WTO and the Olympics are about to be halfway through. You're fine, why do they want to hit you?"

As a boy named Cao Yunhua took some content seen in the newspaper to "popularize science" to the students and reposted some foreign media words, several students who had originally opposed the words gradually decreased, and Cao Yunhua held his mobile phone and continued to read the content above:

"Look, the space garbage produced in this experiment, which says... more than 2,300 pieces of space garbage, which can still be traced. More than 35,000 pieces of space garbage larger than 1 cm and more than 1 million pieces of space garbage larger than 1 mm...it will probably take decades to run out..."

"What does exhaustion mean?"

"This is a satellite orbit, and there is also an atmosphere on it, but it is relatively thin..."

"That shouldn't be..."

Zhao Zizi, who hadn't spoken much, heard this and participated in the discussion, "It's definitely not OK to make space garbage..."

"Breaking the truth."

Liu Yu, who was a little "angry young", just returned to his seat. After understanding what was going on, he immediately stood up, "If you don't develop missiles, are you waiting to be beaten? The Eight-Nation Alliance has just left for a few years and forgot?"

“That’s two different things.”

Cao Yunhua immediately retorted tit-for-tat, "National defense is to defend the country, not an arms race, let alone a space race? And not to mention anything else, how to deal with so much space garbage? Does anyone care? What if they all do this?"

"Yes, this is just like protecting the environment."

Zhao Zizi immediately agreed with Cao Yunhua, "Look, we are full of black smoke, all kinds of pollution, and garbage thrown everywhere... If it were the end of the world that day, it would probably be done by humans themselves."

"Don't change your concept."

Liu Yu knew that environmental protection could not be said, so he brought the topic back to the topic, "Aren't you talking about anti-missile satellites?"

Cao Yunhua corrected: "It's an anti-satellite missile."

Many people burst into laughter, and Liu Yu's expression was a little awkward, but he still refused to admit defeat: "No matter what, just do it."

"Okay, you say."

Liu Feng signaled Cao Yunhua not to rush to argue with others first, and looked reasonable like "We want to let others speak and then reason." Cao Yunhua said: "Okay, then what is the significance of this anti-satellite missile? What is it not a space arms race?"

"How do I know?"

Liu Yu had never paid attention to this matter at all, so he just followed the argument, so he could not say it, "Anyway, what Guo Jing did must make sense."

"What's the reason? How much does a missile cost? It's only a few hundred thousand? Including R&D, it's definitely more than tens of millions, so why can't this money be used?"

"yes……"

This conversion of money has touched many people. After all, this is something that is related to everyone's interests. Especially some students from rural areas agree with this principle. With so many poor people, where is it not good to spend this money?

"I……"

Liu Yu couldn't speak for a moment, looked around and said to Fang Chang'an: "Fang Chang'an, you say it!"

After half a semester, I often played basketball together in the same dormitory. Everyone has some understanding of the concepts and tendencies of all aspects. Although I was a little disliked by Fang Chang'an at the beginning and thought he liked to pretend too much, after getting along with each other, Liu Yu was quite convinced of Fang Chang'an, so the first ally that came to my mind at this time was him.

The classmates in the classroom immediately turned around and looked over. Fang Changan, who was reading extracurricular books seriously, looked up, then stretched and sighed, "Do you know GPS?"

The group of people looked at each other for no reason, not knowing why he asked this.

"Of course I know!"

Cao Yunhua actually wanted to say "nonsense". If it were Liu Yu's question, he would have said that, but Fang Chang'an still had to give him some face, and Liu Feng had already shut up very simply. Of course, this was not a coward, but cautious, and was about to see what Fang Chang'an was going to say.

"Do you know Galileo?"

Zhao Zizi asked in confusion: "Didn't Galileo die long ago?"

"It's not that Galileo."

Cao Yunhua knew a lot, so he turned to Fang Chang'an: "Are you talking about the Galileo satellite navigation system in the EU?"

Fang Chang'an nodded, and Cao Yunhua asked again: "What does this have to do with anti-satellite missiles?"

Fang Chang'an smiled and said, "Don't worry, the relationship between Europe and the United States is closer to us, right?"

"Of course."

"We can use gps, can we use it in Europe?"

"Absolutely."

"Europe has ready-made GPS available, and it is well built. Why do you have to spend more on yourself to build a satellite navigation system from scratch?"

No one speaks.

Fang Chang'an continued to ask: "Have you heard of the Galaxy incident?"

Cao Yunhua, Liu Feng and others looked at each other and shook their heads. Instead, Su Xuan thought about it and asked: "Is it the Galaxy cargo ship from 1993?"

Fang Chang'an was a little surprised and nodded. Seeing that the classmates were all looking at him, Su Xuan became a little shy, and she pursed her lips slightly. She looked very good. She said embarrassedly: "Don't look at me, I've heard my grandfather mention this name... I don't know what's going on."

Fang Chang'an said: "In 1993, a cargo ship was sailing well on the high seas. The US suddenly jumped out and said that there were prohibited items on your ship, and asked to stop for inspection. Then he sent a warship and planes to track it. Then we stopped the ship and stopped on the high seas. We sent people to inspect it ourselves, and there were no prohibited items. However, people did not believe it and insisted on sending people on the ship to inspect it. We did not allow it. Finally, we proposed to let a third party inspect it. They still disagree... The stalemate was held for nearly a month, and the Galaxy was parked on the high seas. The food and drink on the ship were gone, and there was no supply, because they locked up GPS for you and let you go. You didn't know where to go on the ocean..."

Zhao Zizi was stunned for a while and said, "Then let them check it out, there is no banned anything anyway..."

"You're farting."

Liu Yu swears directly, "That's the high seas, not their country. Why should our ships make them check as soon as they want? He told me that you have stole something and want to search for you. Do you want to search for it?"

He was not very polite, and Zhao Zizi's expression was not very good because of this. He stood up and said, "Come on, search, just search."

"Oh, don't interrupt."

Su Xuan angrily said, then continued to ask Fang Chang'an: "Did they check it in the end?"

"I checked, otherwise what can I do?"

Fang Changan shrugged, "Then the EU wants to play Galileo and invite us to join us. Their skills are better than ours, so we quickly agreed to join and gave the money, but later they changed their leaders and had their relationship with the Americans fixed, and they kicked us out again... It seems that the money has not been refunded yet."

"But there seems to be no movement in Galileo Navigation now, because the Americans do not allow it, saying that if you dare to do this, you put the satellite on it and I will shoot it down for you."

"We are now preparing to vigorously build our own global satellite navigation system... to understand why we need to experiment with this anti-satellite missile? Otherwise, we can master the technology in this way, and we may not have to shoot down and do an experiment."

"Then I understand!"

Liu Yu squinted his eyes a little, and at this time he blinked his little eyes and looked excited, "That means that we also have this kind of missile now. If you dare to attack our satellite, I will shoot down yours too. Is that what it means?"

"almost."

Cao Yunhua was obviously a little unwilling to accept it, and he didn't know what to say for a while. The other students were somewhat impacted. Didn't they say that world peace? Why did it sound like they were not peaceful at all?

Su Xuan asked again: "Fang Chang'an, how do you know these things?"

"I just saw it."

Fang Chang'an didn't say much. In fact, if Liu Yu hadn't called him directly, he wouldn't have participated in the discussion. He was no longer a junior high school child. Each had his own prototype of his understanding of the world and would gradually improve in his later life. When he went to college in his previous life, he still had various things like "China is not good, it shouldn't be here." At that time, could he think that after graduation, he would take the initiative to watch their own patriotic videos online?

As long as you are not spiritually outward, you will sooner or later realize the truth of this world.

Compared with the cognitive bias of several students, what he cared more about is whether completing the anti-satellite missile experiment at this time means that the big strides of Beidou navigation actually started at this time?

This touched him a little recently about whether to choose the path of whether to compete with all kinds of bigwigs. He once had the idea of ​​"I want to set an example for Chinese technology companies", but just a flash, and he quickly returned to normal rational thinking.

Then in the morning computer class, Liu Feng gave him a "best kill", which finally made Fang Changan make up his mind - before the computer class started, Liu Feng gave him a USB flash drive, and Fang Changan gave him a questioning look. If this was not in the class, he almost doubted what kind of movie it was inside.

Liu Feng said three words without any expression: "I've written it."

Fang Changan was stunned for a moment before he realized what he meant. He inserted the USB flash drive into the computer. Song Tang, who was sitting next to him, gave Liu Feng a seat when he saw this. Liu Feng waved his hand and signaled not to sit.

There is only a file with exe suffix in the USB flash drive. Fang Chang'an clicked to install it. After opening it, a box popped up on the screen. In the ugly interface, there is a rabbit standing on the road. Liu Feng said behind it: "I don't know what to do, so I made a small game, which is similar to Mario. The rabbit you press the button will jump..."

Fang Chang'an tried it and it really worked. He was surprised for a moment. Looking back at Liu Feng, Liu Feng couldn't help but raise his head. Then he realized that he was sitting in Fang Chang'an so that he could not see his shocked and envious expression. So he lowered his head and said, "This is very simple. I actually spend more time writing about what I'll be faster..."

"sharp!"

Fang Chang'an praised him without hesitation and gave him a thumbs up. The classmates around him also came over to "see". Liu Feng was proud and unwilling to show it. He seemed to be very shallow and endured it very hard, so he waved his hand and prepared to go back to his seat. No one could be proud of it when he saw it.

"I'll give you a suggestion."

Fang Changan stopped him, "Since you write a game, it's better to make a simpler one, but you can continue playing... Of course, I'm not saying that you can't play the one you wrote, but I'm giving a suggestion."

"you say."

"Design a bird to fly in a cave. There are spikes everywhere in the cave, and there are spikes on the top and bottom. The bird must constantly adjust the height up and down and fly upwards. If the mouse clicks, it will fly upwards. If it doesn't click, it will fall down. It can be understood that clicking means flapping its wings... It can be as difficult as possible. If it hits a spike, it will hang, and the distance is the fraction."

Liu Feng thought for a while and said, "This is very simple... When will you want it?"

Fang Chang'an smiled and said, "I don't want it, I'll give you a suggestion. Try writing it when you have time."

"OK."

Liu Feng didn't talk nonsense, and simply returned to his seat and began to think about how to write this thing... The other students were still amazed and took turns to experience the boring game of the rabbit jumping and jumping out by Liu Feng. After a long time, there was no problem with the game. Fang Chang'an also fell into thinking when he saw this.

Fang Changan is not very fake about hardware when it comes to making mobile phones, because he has some understanding of some parameters and other things, and there is also a supply chain. Everyone is an assembly factory, so don’t laugh at anyone. It’s all about publicity and promotion.

He wanted to copy Xiaomi's path of success, and Miui made great contributions at the beginning of its founding, but he knew nothing about these things, so he couldn't help feeling guilty... Liu Feng's "appearance" was right, undoubtedly giving him a reassurance.

Liu Feng is a little stubborn and has to go to school. He can write a runnable game so quickly so much homework... It means that this thing is not as difficult as he imagined!
