Short video spoiler history: The beginning of modern warfare

Chapter 93 Shenzhou

Tang Dynasty, Chang'an City.

Many people in the neighborhood have developed a keen interest in the phonograph. This invention is easy to understand at first glance, and those who are good at hands-on work have already started to work on it.

Inside the palace.

"The essence of sound is the vibration of air?" This was the first time that Li Shimin heard such a novel statement.

Literally speaking, if there is no air, there is no sound?

How to prove it? Li Shimin suddenly thought of NASA's free fall experiment, and perhaps he could do this experiment in that vacuum laboratory.

However, the vacuum laboratory specially evacuated the staff at that time. It seems that the vacuum environment is very harmful to people. The danger of suffocation is one of them, but what about other aspects?
He picked up a pen to write down these thoughts, then looked at the phonograph in the sky, and became more and more delighted the more he looked at it.

The Master stood by a river and said: “The past is like this, it never stops day or night.”

The phonograph can preserve the memory of yesterday. Although it only preserves the sound, it is still fascinating.

The lofty ambitions of youth, the pride of passing the imperial examination, the joy of both host and guest on the wedding day, the sweet words when treating each other as equals, the crying of a baby when he is born, and even the warm greetings from old friends thousands of miles away, there are so many moments that should and can be recorded.

Anyone with a keen business sense knows that this is a groundbreaking invention, a product that is bound to become popular and quickly popularized. Moreover, this thing has both a hand-cranked version and an electric version, which perfectly fills the gap before the popularization of electricity.

Li Shimin tried to analyze from a business perspective and found that industries that rely on pure sound services would be greatly affected, such as storytelling and opera industries. In addition to this, what other impacts would there be?

Li Shimin could not figure this out, nor did he dare to be too confident, because business is changing rapidly and he could not see the trend clearly.

The sky screen switched again.

[Congratulations on the successful launch of the Shenzhou 18 manned spacecraft! #Shenzhou18]

【3, 2, 1, fire! 】

As the three men lying in the sky raised their hands and saluted, the sky camera switched to a distant perspective.

With a loud "boom" sound, the Shenzhou 18, with flames spewing from its tail, slowly climbed up from the ground.

At the same time, a huge amount of white gas spurted out from the flame at the tail of Shenzhou 18. The gas spread, collided and stacked layer by layer, forming a magnificent and dreamy cloud mountain, which was dyed a fiery red by the flames.

Among the clouds and mountains, Shenzhou 18 was like a flying sword dragging a fiery red light, with a blazing flame longer than itself at its tail, flying straight up.

At this time, in addition to the rumbling sound, there was also a series of continuous "firecracker" sounds.

The camera on the sky screen always follows Shenzhou 18, from the ground level to mid-air, and then to an upward-looking angle, watching it slowly change from the size of a tree to the size of a thumb, and then to smaller than the little finger. Shenzhou 18 is like a sharp blade, piercing into the blue sky and white clouds.

When it rose to a point where its figure could no longer be seen, a long "white cloud" was left behind it.

Tang Dynasty, in the imperial palace of Chang'an City.

The emperor and his ministers were all stunned. Was this the actual scene of a rocket launch?
They had previously learned that hot air balloons, airplanes, and rockets each have their own flight principles and application fields. Airplanes are mainly used in transportation, etc., while rockets are mainly used in military, aerospace and other fields.

Looking at the barrage of comments that kept passing by, it was obvious that the Shenzhou 18 at this time was used in the aerospace field, as a manned spacecraft, going into space.

"Outside the earth is space. There is nothing there. What do people in the future go to heaven for?" Li Shimin asked softly, his voice a little dry.

"I don't know."

Li Shimin certainly did not expect them to give any answer. At this moment, his mind was still deeply shocked by the image just now. He knew that there was nothing in the blue sky. After breaking out of the earth, there was space, and that was where the stars were. There was no doubt that Shenzhou 18 was going to break out of the earth and go to some space station.

What is a space station? Does it have a launch speed requirement like an airplane? Is the fuel used petroleum? Why don't the earth, sun, moon, stars, etc. fall down?

[First of all, warm congratulations on the successful launch of the Shenzhou 18 spacecraft! ]

[Let's first review the history of the Shenzhou series of spacecraft. Shenzhou-1999 was our first unmanned test spacecraft. It was launched on November 11, 20. It was the first flight of the Shenzhou spacecraft and the Long March 2F rocket. It flew in orbit for 21 hours and 11 minutes and circled the earth 14 times, verifying the basic design and performance of the spacecraft and laying the foundation for subsequent manned spacecraft.]

[Shenzhou II is my country's first unmanned spacecraft. It was launched on January 2001, 1 and was the first space experiment to be carried out in a self-developed spacecraft]

[Shenzhou V, carrying the first astronaut Yang Liwei, was successfully launched on October 2003, 10. It is my country's first manned spacecraft, realizing the Chinese nation's thousand-year dream of flying into space. This also makes my country the third country after the former Soviet Union and the United States to independently master manned space technology]

[Shenzhou VII, launched on September 2008, 9, was the first spacewalk by Chinese astronauts and another milestone in my country's space history. Astronaut Zhai Zhigang became the first Chinese person to walk in space]

[Shenzhou 2011 was launched on November 11, 1, and successfully achieved space rendezvous and docking with the Tiangong space station on November 11, achieving a major leap in space technology and also a prerequisite for the construction of our space station]

Ming Dynasty, Jinling City, in front of Fengtian Palace.

For Zhu Yuanzhang and others, the shock this time was no less than that brought by the Voyager 1 probe. What they saw was nothing short of magical.

This may be a memory that they will never forget.

From Shenzhou 1 to Shenzhou 17, each Shenzhou spacecraft had its own mission and goals, from unmanned test flights to unmanned spacecraft, and then to manned spacecraft, manned spacecraft extravehicular spacewalks, unmanned spacecraft docking with space stations, manned spacecraft docking with space stations, and so on.

Among them, two clips from Shenzhou V and Shenzhou VII startled Zhu Yuanzhang out of his chair. That was the scene where Yang Liwei was eating. The focus was not on the food, but on the food floating in the air, the notebook flying in the air, and Yang Liwei hanging in the air.
And Zhai Zhigang was also standing in the air five minutes after he left the cabin.

"Is this a miracle?" Everyone in the Science Department was stunned. If they hadn't seen it with their own eyes, it would be hard to believe why these things wouldn't fall down.

"That's why the sun, moon and stars don't fall down."

Zhu Yuanzhang was silent. If he had not seen it with his own eyes, it would be hard for him to imagine that there were such physical rules between heaven and earth, or in the words of later generations, the origin/laws of the universe.

Could it be that what is said in the book "Nanhua Jing" about standing on the wind and traveling between heaven and earth really exists?

At this time, all the ministers stood up one after another. Liu Ji looked at the past mentioned by Tianmu, scene after scene. He had a lot to say and ask, too many.

Hu Weiyong, Song Lian and others couldn't even finish a sentence, "This"

After walking for most of my life, my feet are almost touching the earth. I am ashamed that I still have no idea of ​​the vastness of the world and the mysteries of the universe.

At this moment, Song Lian was relieved of the dispute between the new and old knowledge. If he could hear the truth in the morning, he could die in the evening.

Isn't it that we study hard day and night and travel in the sea of ​​books just to understand the world? What's wrong with learning new or old?
If new knowledge can help us understand the world, then we should accept it. If old knowledge hinders us from understanding the world, then we should discard it.

Even a sage could say, "When three people walk together, one of them can be my teacher." How come people today are unable to accept new learning?
Voyager 1 had already told everyone that the sky is vast and the stars are out of reach, and the two are not on the same level at all. Now it has once again revealed some of the physical laws of space.

"What is it?" Du Ping asked himself, grabbing his head, with a look of pain in his eyes.

"It's gravity, or universal gravitation." Sun Chuanshi's face looked pale, obviously he was overthinking.

In fact, it is very easy to guess. In physics, only Newton's three laws and the law of universal gravitation seem to be related to this thing. Among them, Newton's third law is the principle of rocket launch, so only the law of universal gravitation is related to this.

"Law of universal gravitation?" Du Ping turned his head, his eyes full of confusion.

Zhu Yuanzhang and others also came to their senses, looking confused.

"Tianmu mentioned before that hot air balloons can float because the buoyancy provided by the hot air overcomes the influence of gravity. Even airplanes can take off because the lift provided by the airflow under the wings overcomes gravity."

"Then there is the Shenzhou spacecraft, which uses the force provided by the gases ejected from the combustion to overcome gravity."

"Everything we see in our daily lives, including stones thrown out, is affected by gravity and cannot fly, or float."

"Then why can they float?"

"It's probably because it's too far away, too far from the Earth, and out of reach."

Hu Weiyong and others were silent. This was the first time that they had a deep understanding of the "force" mentioned by Tianmu.

This thing, like electricity and magnetism, cannot be seen or touched, but it is everywhere.

For thousands of years, no one has realized this.

[As you can see, each launch of the Shenzhou spacecraft has an important mission. Do you know what the main purpose of the Shenzhou 18 spacecraft is? ]

[In fact, Shenzhou 6 has three main tasks. The first is to take turns with the crew of Shenzhou . After all, the astronauts on Shenzhou have been in space for months, and it is time to get off work.]

[The second is to carry out space science experiments, involving the fields of space material science, space life science, aerospace medicine, aerospace technology, etc. We will also study aquatic ecological projects in the sky and study the self-circulating aquatic ecosystem in space. In layman's terms, it means raising zebrafish and duckweed.]

[The third is to implement astronaut extravehicular activities and cargo entry and exit. In addition, there are some other tasks such as installing protective equipment, carrying out popular science education and public welfare activities, etc.]

[For example, China has been developing manned spaceflight for 30 years, and it is not just investment without output. Now more than 4000 technological achievements have been applied to various industries, such as memory foam in mattresses and pillows, real-time weather forecasts, water purifiers and diapers, dehydrated vegetable packets in instant noodles, diapers, smoke alarms, etc.]

【.】

[It is not easy for our space industry to get to where it is today. Back then, the United States and Russia led 16 countries to jointly build the International Space Station, but they excluded us because our space technology was too backward. We relied on our unyielding spirit and worked hard all the way until we now have our own space station.]

[Now many foreign astronauts have begun to learn Chinese, because the International Space Station will soon be retired, and we will be the only space station in space at that time]

Jinling City, Hexing Tea and Snack Shop.

Manager Wan and others felt that they had vented their anger. It was too bullying. Why did the sixteen countries join forces to form a space and exclude us?

And we finally built our own space station, and Manager Wan, Mr. Su and others all felt proud.

With the strength of one country, we have achieved the achievements of sixteen countries!
Although it was much later, it was the only space station in the world built single-handedly.

And now, the International Space Station is about to be retired.

"What a fate!" Mr. Su picked up a peanut, crushed it with his cheeks, and chewed it back and forth viciously, making a crackling sound.

"That's right!" Shopkeeper Wan felt the anger in his chest disappear. "Xiao Li, serve the guests some wine and snacks. It's my treat!"

"Good! The shopkeeper is generous!" Many people cheered for Shopkeeper Wan.
