The little maid was eating noodles as usual and didn't care at all.
Xiao Ruxue had at least read a book and knew that the sky was round and the earth was round. But what about the little girl? She couldn't even recognize the words, and it was difficult to read other books except picture books.
For Xuan'er, as long as she can be with her young lady and uncle, it doesn't matter whether the earth is square or round, or even if it is a rhombus, it doesn't matter to the little maid.
But Xu Qing is different!
At this moment, Xu Qing faced the little girl again, and suddenly felt as if he had found a soulmate.
In this feudal society, masters would instill the concept of a round sky and a square earth into their students from an early age, and the students would then instill it in their students when they became teachers.
Any student who listens carefully to the lecture will have no doubts about the theory that the sky is round and the earth is round.
But the little girl was an exception, because she never listened carefully to the lectures. Halfway through, her thoughts flew to the martial arts field to draw bows, shoot arrows, ride horses, and slash.
Others accept the holy words of the venerable sages with almost fanaticism. How could the saints be wrong?
The words of the saint are the truth!
No one has ever dared to have the slightest doubt about the words of the sages, and they simply do not dare to question the errors of the words of the sages.
But just because they don't dare doesn't mean no one dares.
The little girl's attitude towards the highly respected sages of ancient times is different from those of them. As much as they, the scholars, respect the sages, the little girls who don't like reading hate the sages.
She has hated the authors of the Four Books, Five Classics and Poetry Dictionaries since she was a child. It was because of these people that she had a miserable childhood.
Who does she like?
What she likes is people like Xu Qing who write martial arts novels for her and tell her fairy tales by Andersen.
The authority of the sages was nothing more than rubbish in her eyes, and she never took it seriously.
The worldview structure of feudal society, which took thousands of years to take shape, suddenly opened a crack in the worldview of a little girl who never liked studying.
Xu Qing saw the look of approval in Xiao Ruxue's eyes and said, "You are right, the earth we step on is indeed not square, but?"
Xiao Ruxue asked: "But what?"
Xu Qing said: "It's a ball."
Xiao Ruxue said repeatedly: "I said it's not square, but Master didn't listen! I just said it's not square."
But as she was talking, Xiao Ruxue suddenly felt something was wrong: "Wait a minute, what does it mean to be a ball? The ground I'm stepping on is obviously very flat."
Xu Qing said: "What if the ball is made very big? Can you still feel the arc?"
Xiao Ruxue shook her head and said: "That's not right. If we stand on top, then the people, water, land, etc. living under this ball, won't they all fall down?"
Xu Qing said: "Chang'e has lived on the moon for so long and hasn't fallen off yet."
Xiao Ruxue argued, "That's different. Chang'e can fly, but we can't fly."
Xu Qing said: "Then let me ask you another question, why does water flow to lower places and why do ripe apples fall?"
Xiao Ruxue said, "But the apple just fell to the ground. I saw it!"
Xu Qing said: "Then why don't apples fly to the sky?"
Xiao Ruxue's little head suddenly became dizzy. She rubbed her head and said, "I...how do I know...this is a fact."
Xu Qing said: "Have you ever heard of the causal cycle?"
Xiao Ruxue said: "I've heard of it."
Xu Qing said: "Everything that has a cause has an effect. The apple will fall to the ground for you to see the effect. You have to trace its cause through the effect, so that you can gain something."
Xiao Ruxue nodded in understanding. Suddenly she felt that the noodles in her hand were no longer fragrant, and her mind was filled with the ripe apple that would fall to the ground.
The apples shipped from Zhao State are crispy and sweet, especially delicious.
One bite and your mouth is filled with juice.
Suddenly I want to eat apples...
Why do you have to wait for the apple to ripen and fall to the ground?
Can you pick the apple before it falls and eat it yourself?
No one will find out, right?
Oh, there are no apples to eat in winter...
Xiao Ruxue's thoughts started to wander further and further.
Xu Qing looked at Xiao Ruxue who was deep in thought and thought he could make an astronomical telescope for her. Such a scientific woman who has the courage to pursue the truth cannot just go to waste.
If you miss this, who knows how long it will take for the Chu Kingdom to give birth to the second Princess Yongle who is not afraid of anything, who doesn't take anything seriously and dares to question everything.
Princess Yongle was loved by the wise king in every possible way every day. She held it in the palm of her hand for fear of falling, and held it in her mouth for fear of melting. No matter what she said, it was always right.
The same cannot be said for Xiao Ye. If he dared to ask if the ground was round, Xian Wang, who couldn't answer, would probably become angry on the spot and then let him feel the affectionate father's love.
To sum up, Princess Yongle's enlightenment was both accidental and inevitable.
No one else would have dared to be so bold. He might have been tied to a pillar and burned to death as if he was possessed by an evil spirit as soon as he expressed this idea.
Xu Qing told Xiao Ruxue a lot today. Many basic sciences in Xu Qing's eyes became like fantasy or even heresy when put here.
Xu Qing made the little girl understand today that there is only one sun in the world, not a bunch of suns lining up to rise from the east and set from the west.
He also told her that besides the Central Plains and the West, there were many, many unowned lands waiting to be conquered and occupied. With the powerful force of the Chu State, it was entirely possible for the little girl to achieve greater feats than King Qin who conquered Liuhe.
If you start from here and walk straight ahead, you will go in a circle and return here again. However, if you walk in the woods, deserts or even uninhabited grasslands, where you can't find any reliable reference points, you will return to the starting point within a short time, because our
The earth is constantly rotating. Affected by the deflection force of the earth's rotation, you may think you are walking in a straight line, but in fact you are going in circles.
Water will flow downwards and apples will fall because of gravity.
The little girl nodded in understanding, still thinking about the crispy and sweet apple.
It would be great if you could think about this bias while eating an apple.
But now that all the fruits in the cellar have been eaten, the little girl may have to wait until next year if she wants to eat apples.
And when Xu Qing told her that he could make her a telescope that could see the stars clearly, she was extremely happy.
You can magnify the stars many times. If you aim at the moon, will you see Chang'e?
Will you see the laurel tree?
Is there really a fool who can do nothing but cut down osmanthus trees all day long?
These all aroused the little girl's endless curiosity.
