Let me go, these ladies don’t look like good people, are they so vicious? You actually want me to be a eunuch?
Jia Huan's eyes flashed fiercely, and he was already considering whether to kill someone or not.
However, he finally compromised.
After thinking for a moment, Jia Huan couldn't help but said: "It's not impossible to prove it, but I need props."
Princess Anle nodded and said, "What props do you need? Just tell me."
Jia Huan said: "I need a house with very high beams, a rope, a funnel and some sand. The way to prove it is to hang the funnel with a rope and fill the funnel with sand."
"Then you pull the funnel sideways and let go, and the sand in the funnel spreads a line of sand on the ground. What do you think the shape of that line will be?"
Princess Anle said without hesitation: "Do you need to ask? It's naturally a straight line."
Jia Huan smiled slightly and said: "Princess, you will find out once you have time. This is my method of proof."
After saying that, Jia Huan turned around and ran away.
As a result, he failed to sneak away and was directly grabbed by Princess Anle.
"Stop here, don't try to escape. You and I will do this experiment together. If you dare to lie to me, hehe, you will have to go to the consequences yourself."
After that, Princess Anle directly dragged Jia Huan away.
The supervisors along the way looked at everyone they saw and then left as if nothing had happened, pretending that nothing had happened.
Not long after, Jia Huan was dragged into a big house by Princess Anle.
This house meets Jia Huan's experimental requirements.
After a while, all the equipment needed for the experiment was complete.
The funnel was suspended high, filled with sand, and temporarily blocked at the bottom.
Next, Princess Anle ordered a eunuch to pull the funnel and retreat due east.
When you are almost back, remove the blockage at the bottom of the funnel and order the eunuch to let go.
Next, the funnel swings out naturally, and the sand leaked from the bottom spreads a straight line of sand on the ground.
Princess Anle sneered and said: "Jia Huan, what do you think? Is it a straight line? You are really lying to me. I must report it to my father and let you be a little eunuch."
Jia Huan couldn't help but frown and said, "This is just the beginning, just keep watching."
Princess Anle saw that Jia Huan was still speaking harshly, and a sneer appeared at the corner of her mouth.
After a moment, Princess Anle's delicate little mouth opened and she let out an exclamation.
Because at this time, the yarn on the ground has deviated and is no longer a straight line.
This, how is this possible?
Why isn't it a straight line?
Perhaps it's because the sand is constantly decreasing, causing the funnel to shake?
Princess Anle couldn't help but frown and began to think.
As time goes by, the yarn on the ground deviates more and more, leaving oval trajectories on the ground.
These ovals are constantly superimposed to form a mysterious and complex image.
This image is very much like the mysterious starry sky.
At this time, Princess Anle was completely stunned.
She couldn't help but ask Jia Huan, "Jia Huan, why is this happening?"
Jia Huan smiled slightly and said: "This proves that my answer is correct. The earth is rotating."
Princess Anle asked again: "But why weren't we thrown out? Also, the sun obviously revolves around the earth, why do you say that the earth revolves around the sun?"
Jia Huan explained: "We were not thrown out because the ground has an attractive force that pulls us firmly to the ground. Do you see why the ripe apples fall to the ground instead of flying into the sky? You threw them Why do things eventually fall to the ground?”
"It's all because of this gravitational force, and the fact that the earth revolves around the sun. Well, it doesn't actually matter. Just think that the sun revolves around the earth."
This kind of problem is difficult to explain clearly to such a scientifically illiterate person. Jia Huan didn't bother to explain.
Princess Anle said angrily: "No, you must explain clearly, otherwise, I will ask my father to invite you into the palace as a eunuch."
I'll go, you're not done yet, are you?
You threaten me again and again, do you really think I have no temper?
If the tiger doesn't show off its power, do you think I'm a sick cat? I'm afraid you will become even more complacent in the future.
Thinking of this, Jia Huan snorted and said: "Princess, when you are riding a carriage and looking at the scenery outside, do you have such a feeling? That it is not the carriage that is moving, but the scenery outside is moving? This shows that there is Even what you see with your own eyes will deceive you.”
"It is not easy to prove that the earth revolves around the sun, but you can use it as a reference by observing the Big Dipper. Watch the Big Dipper in the four seasons of spring, summer, autumn and winter, and you will find that its handle will rotate, and the directions are Southeast, northwest.”
"And this is not actually the Big Dipper that is rotating, but the earth that is rotating around the sun. Princess, it's getting late today, I'm going back first? If you have any questions, just ask me later."
"However, I am preparing to take the provincial examination this year. In the past month or so, I am afraid I don't have much time. When the examination is over, I will have more time. If the princess has any doubts then, I will definitely tell you everything I know. "
Well, when things came to a head, Jia Huan still gave up.
The person standing behind him is the emperor, he cannot be offended, he cannot be offended.
And Jia Huan discovered that Princess Anle was not actually that savage, she was just a little spoiled.
As long as you follow her and coax her, it can be easily done.
As expected, after hearing Jia Huan's words, Princess Anle couldn't help but said: "I've delayed your class time today. You should go back quickly. Before your provincial examination, can I only ask you one question a day?"
Jia Huan nodded and said: "Of course it is possible, but in the future, princess, can you not ask me to prove everything? Because some issues are really difficult to prove."
Princess Anle stuck out her tongue and said with a smile: "Yeah, I understand, go back quickly."
After Jia Huan returned to the dormitory, he found that only Wei Ruolan was there, while Liu Changqing and Xu Shichang had gone to attend the lecture.
Not long after, Liu Changqing and Xu Shichang returned from get out of class.
Xu Shichang looked at Jia Huan and couldn't help but said: "Brother Jia is so charming and suave. I envy you all. Tell us quickly. The princess asked you to go there all afternoon. What did you do?"
Jia Huan looked at Xu Shichang and Liu Changqing and said slowly: "It's nothing. I just talked about Brother Xu and Brother Liu with Princess Anle. In front of the princess, I will praise you two as rare in the sky and unparalleled on earth."
"The princess admires your talent very much and is preparing to tell the Holy Emperor that you should quietly enter the palace and serve Princess Anle!"
Hearing Jia Huan's words, Xu Shichang and Liu Changqing couldn't help but take a breath.
Xu Shichang couldn't help but come up and strangle Jia Huan's neck: "Brother Jia, how can you be so vicious? I will fight you!"
