Chapter 649: Basic Science
Xiao Ruxue has read books anyway, and knows the roundness of the sky, where is the little girl? I can't read all the characters, and it's hard to read other reading materials 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, even if it is a rhombus, it doesn't matter much to the little girl.
But Xu Qing is different!
At this moment Xu Qing faced the little girl again, and suddenly felt as if he had found a confidant.
In this feudal society, the concept of a round sky and a round earth was instilled in the students by the master from an early age, and the students became teachers and then instilled in their students.
All the students who listened carefully to the class would have no doubts about the round sky and the earth.
But the little girl was an exception, because she had never listened to the class seriously, and when she was halfway through her thoughts, she flew to the martial arts field to draw a bow, shoot an arrow, ride a horse, and hack and kill.
Others accepted the venerable words of the sages almost with a fanatical attitude. How could Saint 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 dare not question the mistakes of the words of the sages at all.
But they dare not mean that no one dares.
The little girl's attitude towards the ancient sages who are highly respected in ancient times is different from those of them. How much they respect the sages, the little girl who doesn't like reading hates the sages.
She hated the authors of the Four Books, Five Classics and Poetry Dictionary since she was a child, and it was because of them that she had a miserable childhood.
Who does she like?
What she likes are people like Xu Qing who wrote her martial arts stories and told Hans Christian Andersen's fairy tales.
In her eyes, the authority of the sages is like a fart, and she never takes it seriously.
The feudal worldview structure that took thousands of years to form, let a little girl who never liked to study cut a crack abruptly.
Seeing the approving look in Xiao Ruxue's eyes, Xu Qing said, "You're right, the earth we're stepping on is indeed not square, but?"
Xiao Ruxue asked, "But what?"
Xu Qing said: "It's a ball."
Xiao Ruxue said brilliantly again and again: "If I say it's not from Fang, Master won't listen! I'll say it's not from Fang."
But while talking, Xiao Ruxue suddenly felt something was wrong: "Wait a minute, what is a ball? The ground I'm stepping on is obviously very smooth."
Xu Qing said: "Then what if you make the ball bigger? Can you still feel the arc?"
Xiao Ruxue shook her head and said: "That's not right, then if we stand on it, the people living under this ball, the water, the land, won't they all fall down?"
Xu Qing said: "Chang'e lived on the moon for so long and didn't fall off."
Xiao Ruxue argued; "That's different, Chang'e can fly, but we can't."
Xu Qing said: "Then let me ask you another question, why does the water flow downhill, and why does the overripe apple fall down?"
Xiao Ruxue said, "But apples just fall to the ground. I saw it!"
Xu Qing said: "Then why don't apples fly into the sky?"
Xiao Ruxue's little head became dizzy for a moment, she rubbed her head and said, "I...how do I know...this is the truth."
Xu Qing said: "Have you heard of the Karma cycle?"
Xiao Ruxue said: "I've heard of it."
Xu Qing said: "When there is a cause, there is an effect. The apple falling to the ground is the effect for you to see. You have to use this effect to trace its cause, so that you will gain something."
Xiao Ruxue nodded half understanding, and suddenly felt that the noodles in her hand were no longer fragrant, and her mind was full of the apple that would fall to the ground when it was too ripe.
The apples shipped from Zhao Guo are crunchy and sweet, especially delicious.
One bite, mouth full of juice.
Suddenly craving an apple...
Why do you have to wait for the apples to fall to the ground when they are ripe?
Can you pick off the apple before it falls and eat it yourself?
No one should find out, right?
Oh, no apples to eat in winter...
Xiao Ruxue's thoughts started to drift further and further away.
Xu Qing looked at Xiao Ruxue, who was lost in thought, and thought that she could make an astronomical telescope for her. Such a science girl who had the courage to pursue the truth couldn't just be wasted.
If you miss this, who knows how long it will take for Chu to give birth to the second Princess Yongle who is not afraid of anything, who dares to question everything without To put in one's eyes.
Princess Yongle is loved by the virtuous king every day, she is afraid of falling if she holds it in the palm of her hand, and afraid of melting if she holds it in her mouth, no matter what she says is right.
Xiao Ye couldn't do it anymore, if he dared to ask if the ground was round, the virtuous king who couldn't answer would probably become angry on the spot and then let him feel the kind father's love.
In summary, Princess Yongle's enlightenment was both accidental and inevitable.
No one else would dare to be so bold. Maybe this idea would be regarded as a demon possessed and tied to a pillar and burned to death as soon as he uttered it.
Today Xu Qing told Xiao Ruxue a lot, and many basic sciences in Xu Qing's eyes turned out to be like fantasy or even heresy.
Today Xu Qing let the little girl understand 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 apart from their Central Plains and the West, there are many, many unowned lands waiting to be conquered and occupied. With the powerful force of the Chu State, the little girl is entirely possible to make a greater feat than King Qin's sweep of Liuhe.
If you start from here and go straight ahead, you will go around in a circle and return here, but if you can’t find any reliable reference points in the woods, deserts or even uninhabited grasslands, you will return to the original point after a short walk, because our The earth is constantly rotating. Affected by the deflection force of the earth's rotation, you think you are walking in a straight line, but in fact you are circling in situ.
Water flows downhill, and apples fall because of gravity.
The little girl nodded half understanding, still thinking about that crisp and sweet apple.
It would be great if I could eat an apple while thinking about this biased force.
But now that the stored fruits are all gone, 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 overjoyed.
You can magnify the stars many times. If you point it at the moon, will you see Chang'e?
Will you see the laurel tree?
Is there really a fool who can't do anything but cut laurel trees all day long?
All these aroused the little girl's endless curiosity.
