Zhu Yuanzhang looked particularly happy.
I just feel that my eldest grandson is worthy of being my eldest grandson.
This child has been smart since he was a child, just like me as a grandfather.
Even smarter than my grandfather!
There were some questions that he, a grandfather, didn't expect, but he asked them.
Let’s see how this bastard Mei Yin responds!
The sky is round and the earth is round, this is the conclusion that our ancestors have come to many years ago.
The understanding of heaven and earth has been concluded.
It turned out well for him.
After arriving at his place, he had to make some changes.
It is said that the earth is a ball.
Next, I will take a good look at what kind of nonsense he uses to prove that what he said is right.
Even if Mei Yin talks about flowers, the land will still be flat!
There is absolutely no way it could be a ball!
When he was thinking this, Mei Yin in the simulator also spoke.
“Before, I still thought that the sky was round and the earth was round, and I felt that what our ancestors said was right.
But since I made a bigger and stronger telescope, I use it to watch the stars and the moon.
I found that what I saw was different.
Also, I often communicate with the crew members of my Ming Dynasty who sailed overseas.
Through them, I discovered an interesting thing.
That is, when they were sailing on the sea.
When I saw the ship appearing in the distance.
The first thing you see is not the whole thing, but the highest mast, and then the sail.
Then there is the hull.
As the distance got closer and closer, finally the entire ship could be seen.
It is said that the water surface is very flat, there are no mountains or flat land.
So, when you see a ship, you should first see the whole ship.
Instead of seeing the top of the mast first, then the sail, and finally the entire ship.
So, I gave this question some thought.
Discovered that the ground is not flat, only round.
Only in this way can such a phenomenon be reasonably explained. ”
As Mei Yin spoke, he took out a small sailboat that had been prepared in advance.
Then he put it on the globe and started doing experiments with Zhu Xiongying.
His movements confirmed that what he said was indeed the case.
On the globe, after conducting experiments with the help of the globe.
Mei Yin placed the small sailboat on a flat table.
What you see directly is a whole ship.
"Did you see that?
That's it.
So after conjecture and verification, I think the only proof that can explain this phenomenon is that in the past, our understanding of some things was wrong.
This land is not flat,
But it is like this only if it is a ball as a whole. ”
Zhu Xiongying, who was in the simulator, listened to what Mei Yin said and then conducted some experiments with Mei Yin himself.
Everyone seemed very excited.
I feel very good,
All of a sudden, the motivation to study was boosted.
I just think it is really interesting to study with Mei Yin, my second uncle.
In Wuying Hall, Zhu Yuanzhang, who was watching the simulator, heard what Mei Yin said.
There was a look of thought in his eyes.
There is still some enlightenment.
His attitude has changed a lot,
I no longer think Mei Yin is talking nonsense.
This matter does seem to make some sense.
Then, he thought of a scene he saw when he was on the grassland.
That's when someone came galloping on horseback in the distance.
It is not that people and horses are directly seen.
But see the head first.
Then there is the whole person.
In the past, he didn't think there was anything.
I just think it's a normal phenomenon.
But now, after listening to what Mei Yin said, I suddenly realized that these things have a lot in common.
This...it seems like things are really as Mei Yin said!
The land underground is really a ball!
Only a ball can explain this phenomenon clearly,
When such thoughts arose in his heart, Zhu Yuanzhang felt dumbfounded.
He really didn't expect that things would be like this.
This was something he had never thought of before.
Regarding Mei Yin, more and different opinions emerged.
This kid Mei Yin sees things from a different angle every day!
The same phenomenon seemed normal to me and others.
Never think too much about it.
But he was able to directly connect from such things to the earth where he and others lived.
Moreover, we can also draw such a conclusion from it, which seems very reasonable.
This kid is really no ordinary person!
I don’t know how I grew this brain!
At this time, Zhu Yuanzhang's understanding of the round sky and the square place had undergone a great change.
He no longer feels that no matter what Mei Yin says, even if he talks about flowers, he will think that the sky is round and the earth is round.
What Mei Yin said is wrong.
Thinking like this, I noticed what Mei Yin just said.
A better telescope?
When did Mei Yin make this?
Apparently, he also used this thing to look at the stars and the moon.
Could it be that you can also bring the stars, the moon and other things in front of your eyes at once?
Then...is there Chang'e on the moon? Is there a Jade Rabbit? Is there a laurel tree?
What does Chang'e look like?
Zhu Yuanzhang suddenly had infinite reverie in his heart.
Why don't these things show up in the simulator?
Zhu Yuanzhang felt itchy in his heart.
I also wrote this idea down.
From now on, we must always pay attention to the situation in Mei Yin.
Let’s see when Mei Yin can make something like this.
Use it to watch the stars and the moon.
At that time, I must use this thing as soon as possible to take a good look at the moon.
It would be great if there really was Chang'e on it!
You can also see what these people are like.
While thinking about this, Zhu Yuanzhang also had a big doubt in his heart.
That's what my eldest grandson proposed. Since this thing is a ball, why can't I feel that it is a ball when I stand on it?
And it’s very stable to stand on it.
And when his doubts arose, Mei Yin in the picture also spoke at this time.
"As for what you said, Xiongying, if it is a ball, why we can't feel it and can still stand so firmly is easy to explain..."
Easy to explain? !
After Zhu Yuanzhang heard what Mei Yin said in the simulator.
They couldn't help but blinked.
For a moment, they all doubted whether they heard correctly.
Is this thing easy to explain?
How is that possible!
It's obviously not easy to explain at all?
He wanted to see what Mei Yin had to say about this.
Can you tell me a particularly convincing reason like you just did?
"The reason why we can't feel this is a ball.
It's because this earth is really too big.
Moreover, the surface is not that smooth.
On the surface, there are mountains, flatlands, ravines and many other things.
And we humans are too small compared to the huge earth.
It is simply much smaller than a small ant landing on the globe. It is also because of this that although the earth is a ball.
But within a certain area, from our perspective, we can't see any curvature.
Because it's so big!
In addition, there are various topography and landforms on the surface of the earth.
So we can’t feel this..."
This is what it looks like!
Zhu Yuanzhang thought about it and felt that this matter did make some sense.
"In addition to this, there is also the role of this thing.
Let us stand on this without slipping.
This is a fundamental thing.
I call this thing gravity.
This thing can also firmly attach us to the earth.
Can help us stabilize. ”
What the hell? !
Zhu Yuanzhang, who just now felt that what Mei Yin said made sense, suddenly heard what Mei Yin said.
They couldn't help but be stunned for a moment.
Why does it sound like Mei Yin's words have begun to sound unreliable?
So what kind of power is so powerful?
Can you suck so many people and so many things?
Thinking this, he jumped on the ground.
Isn't it easy to leave?
A slight jump can lift your feet off the ground.
It’s not as outrageous as Mei Yin said!
Zhu Xiongying in the simulator also seemed confused at this time.
Obviously, he didn't understand what Mei Yin meant.
"Things are actually quite easy to understand.
You will understand when we do something,”
As he spoke, he took out a small ball and handed it to Zhu Xiongying,
Let Zhu Xiongying throw the ball up.
Zhu Xiongying took it and threw it hard, and the ball flew up.
Then it landed on the ground and bounced a few times, rolled a certain distance and stopped moving.
"Xiongying, what can you see from this?"
Zhu Xiongying said: "I threw the ball up, and then the ball fell to the ground again."
"Yes! Very good! Xiongying, you said it very well!"
Zhu Yuanzhang looked at the simulator screen.
I just feel like I can't turn my head around anymore.
In his opinion, what Mei Yin was doing was perfectly normal.
Moreover, what Xiongying said was very simple.
How did it become so good?
Then can you tell your uncle why this ball fell down again after being thrown away?
Rather than keep running to the sky? ”
Zhu Xiongying was stunned for a moment.
Then he immediately said: That...it's because I used too little strength.
If I grow older, I will be stronger.
You can throw the ball farther and higher. ”
Zhu Yuanzhang nodded, yes! good! My eldest grandson is so smart!
That’s the truth!
Mei Yin, who was among the simulators, also nodded.
"Xiongying, what you said does make some sense.
But even the strongest person can throw the ball higher.
But after all, there are some limits.
The ball will still fall down, and eventually it will fall to the ground.
Then...why is this? ”
Zhu Xiongying couldn't help scratching his head.
Fell into deep thought.
Let alone Zhu Xiongying.
Even Zhu Yuanzhang, who was watching the simulator, looked unusually confused.
He also couldn't think of any good explanation.
This person only thinks that Mei Yin, a bastard, is not deliberately making things difficult for his eldest grandson, right?
What are these questions he asked?
These are all things that are taken for granted. What’s there to ask?
Mei Yin said: "This is the universal gravitation I just mentioned, it is working.
This means that there is a force on the earth beneath our feet.
It can attract many things on this earth to come down.
Not allowed to leave the ground.
It is also because of this that we humans will be able to walk steadily on this ground.
Will not fly out for various reasons...
Can you still say that? !
Zhu Yuanzhang was stunned for a moment.
Zhu Xiongying in the simulator seemed even more confused.
After doing this for a while, he suddenly seemed to think of something.
I suddenly became happy.
"Second uncle, second uncle, what you said is wrong!"
Mei Yin smiled and said: "What's wrong?"
"Second uncle, whatever you just said must be attached to this ground.
However, birds can fly, and butterflies and dragonflies can fly in the sky.
Isn't this just getting off the ground? ”
good!
As expected of our eldest grandson?
In the Wuying Hall, Zhu Yuanzhang, who was watching the simulator, couldn't help but stretched out his hand, slapped his thigh and praised it loudly.
"This kid is so smart!
At first glance, he is the son of his old Zhu family! ”
Now let’s see how this bastard Mei Yin will answer and explain this question next!
Let's just say that Mei Yin is talking nonsense.
These are all normal things, but he insists on saying them in such profound ways.
What if Mei Yin was defeated by a child like his eldest grandson?
Then this becomes fun.
Mei Yin in the simulator was unhurried.
"Xiongying, you can think of these, it's really good.
There is some truth in what you said.
Birds can indeed fly in the sky.
However, they can fly because they flap their wings to fly.
But once they stop flapping their wings, they still fall down.
Either fall on the ground or stand on a branch.
After all, it cannot fly for a long time.
Isn't it true that there is still a gravitational force attracting them? ”
Zhu Xiongying in the simulator fell into thinking after hearing this.
Zhu Yuanzhang in Wuying Hall was also confused by what Mei Yin said.
By the way, some time ago, I saw Mei Yin, a bastard, trying to teach his eldest grandson in the simulator.
Zhu Yuanzhang also brought some thoughts on teaching.
I feel that what Mei Yin said must be very simple.
You will understand it as soon as you hear it.
But who would have thought that after listening to it for a while, I would find that I didn't understand many things.
I can’t figure it out.
Mei Yin, this bastard, always has so many strange ideas.
Obviously many of them are very simple and easy to understand.
But he had to say so many things.
It makes people unable to understand the world.
"Second uncle, how did you come up with this universal gravitation?"
In the simulator, Zhu Xiongying looked at Mei Yin and asked, with some curiosity.
When Zhu Yuanzhang heard this, he immediately became stunned.
He stared at the simulator without blinking.
I want to see what Mei Yin will say on this matter.
He is also very curious about this matter...
