Super Military Scientist

The first thousand and ninety chapters have a day of culture

Also, how these rockets and spacecraft were developed. In space, how do these rockets and spaceships fly?

You must understand these problems now, or else, if you encounter some spacecraft malfunctions after you fly for nine days, you just don't know what to do.

So, you are now to study these theoretical knowledge well. You must learn these theoretical knowledge. Only in this way, you will know how to solve the problem of the spacecraft after flying on the rocket for nine days.

Otherwise, you don't even know what to do! So, now you have to learn these theoretical knowledge well.

In a sense, these theoretical knowledge are more important than your physical fitness. Because your physical fitness only guarantees that you can live a healthy life in space. It will not help you solve some machine failures encountered in space.

Therefore, all of us must pay attention. Starting today, we must work hard to learn these theoretical knowledge. Only by mastering these theoretical knowledge can we grow into a qualified astronaut. "

After Zhao Zhongyao finished speaking, he looked at everyone and said: "Now, you first look at these learning materials, we will study the content of Chapter One today. If you don't understand, you can also ask me.

What we learned in Chapter 1. In fact, the relationship with our astronauts is still very great. Because the content we learn in each chapter is mainly about some knowledge about space.

What is space? In the eyes of ordinary people, it cannot be the blue sky and white clouds. This is just space in the eyes of ordinary people. In the eyes of our astronauts, space is another matter.

We astronauts live and work in two hundred kilometers of space. What does two hundred miles of space look like? We have never seen it personally until now. It's just that we know some atmospheric components from some theoretical knowledge.

We all know that the thickness of the earth’s atmosphere is between 2,000 and 3,000 kilometers. The space for our astronauts is generally between two hundred kilometers and three hundred kilometers.

In this way, do you feel that we are still quite close to the ground? Does it mean that in two hundred kilometers of space, it is similar to the surface we live on now. If you think so, you are definitely wrong.

Everyone knows that the atmosphere on our planet is thousands of kilometers thick. The thickness of the atmosphere that can truly be suitable for human existence is about ten kilometers. Because, within the thickness of ten kilometers, it belongs to the troposphere. The oxygen content in this layer of the atmosphere is very high. Only in this atmosphere can people breathe freely.

But when the altitude of the atmosphere increases to more than 20 kilometers, the oxygen content can be reduced by half. In such an environment, humans will feel difficulty breathing.

When the altitude of the atmosphere increases to more than 30 kilometers, the oxygen content in the air is already very small. Human beings can no longer survive in such a space. And our astronauts are going to live in two hundred kilometers of space. In such a place, there is no oxygen at all. Human beings simply cannot live in such a space.

Let alone oxygen. Even gravity is very small at this height. When a person reaches this height, he has almost reached the point of weightlessness. In such a space, ordinary people cannot live at all.

What we are learning in this first chapter today is some knowledge about the atmosphere. Don’t feel that we seem to have learned this knowledge before. It feels like there is nothing to learn.

If you think so, then you are wrong again. The geographical knowledge you learned before. It's just simple knowledge, just let you understand some of the composition of the atmosphere. There is no more explanation about this space knowledge at all.

But the knowledge we have to learn now is different. What we have to learn is some very detailed space knowledge. Even the knowledge of the atmosphere is very detailed. You must study hard. These theoretical knowledge will be very helpful for your future life in space. "

After Zhao Zhongyao finished speaking, he looked at everyone and wanted to hear their opinions.

These pilots, after listening to Zhao Zhongyao's speech, began to discuss again.

"Unexpectedly, to be an astronaut, you have to learn knowledge about the atmosphere. We didn't have learned this knowledge before when we were in college."

"Yes, we are pilots. We learned this knowledge when we were in the military academy."

"Yes! We have studied before. However, I just looked at this knowledge, and it feels that it is much more detailed than when we were in college."

"It seems that we still have to study hard! Otherwise, we will not be able to meet the requirements of Mr. Zhao!"

After hearing what Zhao Zhongyao said, the pilots began to talk quietly.

After Zhao Zhongyao waited for them to discuss for a while, he looked at them and said: "Okay, you have seen it almost, let me tell you the main content of this first chapter!"

After Zhao Zhongyao finished speaking, he picked up the chalk on the desk and wrote a few words about space and atmosphere on a blackboard hanging on the wall.

After he finished writing, he gave a lecture to everyone.

The ten astronauts, as soon as Zhao Zhongyao started to lecture, they all listened carefully. After all, there were ten people in this classroom. If anyone is lazy in this class, the teacher will see clearly.

Zhao Zhongyao took that copy of the learning materials and told everyone about the content of the first chapter.

After listening to everyone, they also felt that the knowledge about the atmosphere that they had learned before was really too simple. The knowledge that Zhao Zhongyao talks about now gives them a deeper understanding of the entire earth’s atmosphere.

After Zhao Zhongyao spoke, he looked at the pilots and said, "Okay, I have finished speaking now. You feel that there are some places that you don't understand! If you don't understand, you can raise your hand to ask questions now. "

After these pilots heard what Zhao Zhongyao said, some felt that they didn't understand well, so they raised their hands to ask questions. Zhao Zhongyao also gave them a serious explanation. They all understood the knowledge on the learning materials.

This day is over. Zhao Zhongyao taught them one day of class, and the ten astronauts of them just became students for one day. It feels like it's back to the time of entering the military academy.

At night, after Li Chengwei and the others returned to the dormitory, they began to talk and laugh again. After all, this first day's life was somewhat calm for them. Everything is not as terrible as they thought. That is to be a student.

"Hey, the astronaut recruits have nothing special about their lives! Isn't it just learning some cultural knowledge!" Yang Chengwei said now looking at Zhai Fanggang and Jing Tianpeng.

"I think, Mr. Zhao is also thunderous and rainy! We will not be strictly trained, that is, to learn some cultural knowledge!" Zhai Fang just heard Yang Chengwei's words, so he echoed this sentence.

"We don't need to panic. We have been pilots for more than ten years. What kind of air danger has not been encountered. Even if you fly to an altitude of two hundred kilometers, it is not the same as dealing with problems in the work of some spacecraft. I feel that we don’t have to worry at all, as long as we can be good pilots, we can be good astronauts."

Jing Tianpeng heard what Yang Chengwei and Zhai Fanggang said, and felt that the life of this astronaut's recruit company was really nothing special, and there was no need to worry about anything.

But Yang Chengwei was a little worried about what Zhao Zhongyao said during the day. After all, Zhao Zhongyao said. Their training plan is physical fitness classes on the 1st, 3rd, 5th, and cultural classes on the 24th, 6th. Today is Tuesday, so they first took a day of culture class. Tomorrow is Wednesday, but they are going to have physical training.

What will this physical class look like! These reserve astronauts also have no bottom in their hearts. They don't know what the physical fitness class of this astronaut looks like.

"Hey, you said, what will our astronaut's physical fitness class look like? Is it similar to the common subjects we trained in the recruit company!" Yang Chengwei thought of tomorrow's physical fitness class, and he looked at Zhai Fanggang like this Said with Jing Tianpeng.

"What else is going on? It must be about the same subjects as our recruit company. Are we the recruit company now! Of course it's not nearly the same as the previous recruit company." Zhai Fang just heard Yang Chengwei's words and said again.

"Yeah! We don't have to worry at all, but it's just like the recruit company. What else can there be, it's all the same, we don't have to worry about it." Jing Tianpeng agreed with Yang Chengwei's words.

The three of them don't pay attention to tomorrow's physical fitness class now, feeling that it is just the same thing.

After talking for a while, the three went to bed.

When they first lay down, everyone couldn't sleep either. After all, after changing to a new environment, this identity was different from before, and it naturally made people feel a little excited.

Yang Chengwei, Zhai Fanggang, Jing Tianpeng and the three of them have their beds next to each other. They are not sleepy now. Although they are lying on the bed, they are still chatting!

"Oh, Cheng Wei! You said, on the first night of our recruit company, will we have a special job! This first night, supposedly, will leave us with some impressions!"

Zhai Fang just thought of when he was in the recruit company, but on the first night, their company commander gave them a slap in the face. The first night of the recruit company. In the freezing wind, they came to an emergency assembly.

Thinking of that emergency assembly. Zhai Fanggang is still fresh in his memory. Because the emergency assembly that night was really dramatic. It makes people laugh out loud.

Because the soldiers of these recruit companies are all fresh from the local army. We haven't stayed in the army for a day, so many things can you know! Just this emergency assembly, that was also just heard from the monitor. I have never had such a personal experience. I just heard from the monitor that this thing is very ‘stimulating’. Will make you sleep well all night!

Imagine that a group of soldiers who have just joined the army have never experienced an emergency assembly. Then they suddenly came to the army. At midnight on the first night, they suddenly encountered an emergency assembly. You can imagine what kind of situation it will be.

Now that Zhai Fanggang thinks about the situation at that time, it feels very funny! Later, when he went to military academy and met Yang Chengwei and Jing Tianpeng, he would often talk to them about the fun "first night" he had in the recruit company.

The situation at that time was like this. When Zhai Fanggang and the more than one hundred recruits came to this beautiful military camp from all sides of the motherland, they were very happy.

When they first arrived in the army, the leading cadres were very enthusiastic towards them, and it made people feel that they were back home. It doesn't seem to be a soldier.

That night, due to the hard work of the day, everyone quickly fell asleep.

It was winter, and the strong wind outside was blowing, and everyone was lying in the warm blankets, feeling very comfortable. Just thinking about sleeping until dawn!

But in the middle of the night, when everyone was sleeping Zhengxiang, suddenly there was a rapid whistle downstairs.

"DiDi--DiDi--DiDi--"

The sound was so harsh, it awakened all recruits in the company.

This is the first time such a voice has been heard for this hundred-odd recruit. As soon as this sound came, all the recruits woke up.

But everyone does not know what this whistle means. After all, everyone was in the place before, but rarely heard such voices. Although you can hear such a sound in physical education classes at school, it is definitely not so harsh.

"What are you doing! What kind of whistle was blowing in the middle of the night to prevent people from sleeping." The voice of a recruit with a southwestern accent.

"What's the matter? Whoever is full and holding on, now blow the whistle." The voice of a recruit from the Central Plains area.

"Insane! Blowing the whistle in the middle of the night and preventing Lao Tzu from going to sleep." A recruit who was just a small **** in the place became angry immediately after hearing this sound.

At that time, Zhai Fanggang heard the voices of these recruits and said nothing. However, he knew that a storm was coming, no one wanted to hide.
