Chapter 111 World Map
Not long after, Qin An took out the world map.
Ying Zheng and others were sitting on the stone table waiting anxiously.
The world map, that is the world map of the future, the map of the entire world in Qin An's mouth.
Qin An took the newly drawn world map and said to everyone: "I'm really sorry for keeping you waiting for so long."
Then he placed the world map on the stone table and continued: "This is the world map."
"Why is it round?" Gong Shuyang asked.
"That's a good question." Qin An said, "Because the ground we are standing on is spherical, and we call it the earth."
"Sir, don't be ridiculous. We have been talking about the round sky and the square earth for a long time. You suddenly said that we are standing on a round ball, which makes people laugh out loud. Besides, how can people stand on a ball." Gong Shuyang said immediately. .
Others nodded.
Meng Yi smiled and said: "Sir, your statement is very interesting. Mr. Gongshu, since he dares to say this, he must have his basis. Don't draw conclusions so easily."
Ying Zheng nodded and said, "Yes, we might as well listen to what Mr.
Qin An said: "It's normal for you to have such thoughts. Those of us standing on the ground say that the ground is round. It's actually very simple.
When everyone looks from the mountains into the distance, the last thing they see is the sky, not the same height, or even higher and bigger mountains, right? "
Only then did everyone notice this thing that they usually never pay attention to.
Yes, the last thing I saw was the blue sky, and there was nothing else. No, there was a line, a line connecting the earth and the sky.
Is the ground where we are really spherical and called the earth?
"No." Gong Shuyang said, "How can a person stand on the ball?"
Qin An smiled and said: "Because the earth has gravity. This idea was discovered by a foreign man named Newton.
It's interesting to say that Newton questioned many phenomena that many people were not accustomed to, and finally discovered the conclusion of universal gravitation. "
"What's happening?" Gong Shuyang asked.
Qin An said: "A ripe apple fell to the ground, this phenomenon."
"Isn't this a normal thing? It's not just apples that will fall to the ground when they are ripe. Many fruit trees will fall to the ground when they are ripe." Gongshujia said.
"Yes, I think it's normal. Where else could this ripe fruit fall if it didn't fall to the ground?" Qin An said, "But Newton asked why this apple fell to the ground, and then based on this question .Finally got the answer.
This is the origin of universal gravitation. Through the law and formula of universal gravitation, the density of celestial bodies, the action of force, etc. can be calculated.
This is a bit esoteric, and even if I tell you, you won’t understand it. Let’s continue looking at our world map. "Qin An said.
Everyone was stunned when Qin An said, "What about gravity, Newton?" They could understand every word, but when they were put together, they were a little confused.
Fortunately, Qin An changed the topic to the world map.
Everyone looked at the map again, no longer shocked by why the world map was round.
What's still shocking is that the continents on the world map are all in the east and west.
"Why is it that on the map I see, the land is in patches instead of complete?" Ying Zheng asked,
Qin An smiled and said: "This is a long story, and it starts from tens of millions of years ago, or hundreds of millions of years ago.
But I only know a rough idea, after all, I am not an archeology major. "
Damn it, does time have to start that far back? Who ruled the world at that time? Three Sovereigns and Five Emperors?
Everyone looked at Qin An with stars in their eyes.
Qin An's head was full of dark threads, knowing that he had to tell the story again.
"Oh, this is a long story. In fact, there was only one continent at the beginning of the earth. I don't know what it was like at that time. I only know that major earthquakes will happen every once in a while."
"What is an earthquake?" Meng Yi asked.
Qin An answered casually: "It's the earth dragon turning over. After countless earthquakes, coupled with the impact of sea water, the plate drifted, and finally it became what it is now."
Then Qin An pointed to China on the map and said: "This is China now, carrying an ancient civilization spanning five thousand years.
At present, whether it is economy, technology or military, China is the world's leading power.
Anyone who dares to invade China, whether it is a military invasion or an economic invasion, China will resolutely fight back.
Anyone who offends China will be punished no matter how far away they are. "
"Anyone who offends China will be punished no matter how far away he is." Ying Zheng said excitedly.
Meng Yi asked: "Sir, the world is so big. If we want to travel around the world, I'm afraid we won't be able to do it in our lifetime. How did we draw this map of the world?"
"Haha..." Qin An smiled, "That's a good question.
This is the strength of human beings. With the continuous development of science and technology, humans can now fly into the sky and even land on the moon with the help of tools.
Now that the country has built a space station in space, everyone says that the competition in the future will not be military competition, not economic competition, but technological competition.
Whoever has strong science and technology can become a world power, and whoever can take the lead in developing in space will have the future of this country.
Of course, I don’t know who drew the world map, but I know that the first fleet in the world to sail around the world was called Magellan’s fleet.
This matter is a long story, so I won’t talk about it for now. "
Qin An then introduced the four oceans and seven continents, as well as some current international situations.
This greatly shocked Ying Zheng and others. It turned out that they were frogs in the well, and the world was so big.
Ying Zheng asked: "Sir, the world is so big. It would be very difficult for me to go to other countries like this beautiful country."
"You can take a plane and you'll be there in a few days." Qin An said.
airplane? What is that? Flying hen or rooster?
Qin An saw Ying Zheng and others looking confused, and said with a wry smile: "This plane is a type of transportation, it can fly into the sky, and it is very fast.
You don't have to look at me like that, I can't make that thing by myself. "
Everyone was immediately embarrassed. It seems that they have overthought it. Sure enough, flying to the sky is not that simple.
Young Master Gao said: "But I remember your husband once said that if you want to fly to the sky, you can do it."
"Yes, Sir said that, and I remember it too." Ying Zheng said immediately.
Meng Yi and others were immediately confused. Can they really fly into the sky? Then he looked at Qin An again.
Qin An said without even thinking, "Yes, it's not difficult to fly. But if you want to fly at the same height and speed as a plane, it's impossible."
