Yu Zai conducted astronomical observations on this high mountain that only exists in the mythical world. This is the best place Yu Zai has ever found and seen, allowing him to better explore the mysteries of the world.
Yu Zai can determine many things, such as the trajectories of the stars and the sun and the moon. Their movement results are the same as the data predicted by themselves. However, the original observation data still cannot determine whether it is the correct large universe or the four directions of the cloudy sky.
In the world, Ruanzai's understanding of the field of astronomy is limited to what he has learned. After all, geography and astronomy are two different fields. There is overlap and learning, but it will not go too far.
However, no matter how magical this unexpanded world is, to observe the movement of the sun, we must use the celestial sphere model. The so-called celestial sphere refers to a sphere with the observer as the center and infinite length as the radius outward.
On the celestial sphere, we can see the projection of any celestial body, including the projection of the sun.
Then, the movement of the sun on the celestial sphere that an observer sees on the earth is the apparent movement of the sun. On the apparent movement diagram of the sun, we can determine the sunrise and sunset directions, the length of day and night, and the time at noon in a place.
The position of the sun in the sky.
Hongchao couldn't understand what Yu Zai was doing. He was confused and felt that studying was really hateful.
It’s because of top academics like you that the world of underachievers is so broken, you bastards!
And Chisongzi was also very angry!
Good disciple, I brought you here to level up, not to let you build the wonders of an observatory!
But the dissatisfaction in his heart was still dissatisfaction. He said that he wanted to build a simple observatory, and said that this is also a kind of natural principle, and it can be extended to more natural principles!
As soon as Chisongzi heard this, he immediately ran to help.
Good disciple, if you want Master to do anything, just ask him!
“I once gave Shuhai a stone ball because I had observed it and thought the earth was round.”
“This sounds ridiculous”
Hong Chao was not interested in this and thought that Yu Zai was talking nonsense. If the earth were a ball, wouldn’t he be singing and dancing rap anytime and anywhere?
Hello everyone, I am practicing the Earth’s two-and-a-half-year revolution?
But Yuzai took a new stone ball and made a simple parallel view, making the shape of revolution and autobiography. Hongchao, no matter how poor a student, understood it clearly.
He suddenly began to doubt the whole world.
“Since it’s a ball, why won’t I fall out?”
“For a great power has fastened you to the earth.”
Yu Zai wrapped a rope around the stone ball, and then started to spin it in circles. This new explanation made many problems in the past suddenly come to light. Chisongzi suddenly realized it, but Hongchao fell into fear!
“It turns out there was someone I couldn’t see dragging me away!”
Hongchao was shocked:
“No wonder I always roll out of the straw mat when sleeping. It turns out that this force is also at work!”
In the early morning of the next day, everyone watched the sea of clouds rolling in the east. The outline of the sun appeared, very far away but also very huge. It appeared from Tanggu, moved from the mountains where the sun and moon emerged, and arrived at Qu'a Mountain. At this time,
Data recording has already started.
Hongchao helped Ruzai get a lot of key materials. He searched for them in the mountains because Ruzai wanted to make an ancient astronomical telescope.
The sun has come over, getting closer and closer. Under the brilliance of the evening, it is extremely huge and begins to approach Kuangji Mountain!
Boom!
It was like something made a huge, hollow, reverberating sound, and the waves in the sea of clouds were like angry waves. Yu Zai felt that the sun totem was exploding with power!
Calling!
Ancient totems are the source of strength and spiritual sustenance for humans and gods in the past. They reflect the true nature and principles of all things in the world. In the world of gods and ghosts, and in the world of materialism, illusion and reality are intertwined!
Yanzai felt the wind!
That is the vast wind brought from the eternal distance. Now that you are in this strong wind, the totem pattern of the sun emits dazzling light all over your body, like a real flame.
At this time, Yuzai asked Chisongzi and Hongchao to help him record the data, and then he was ready to start congratulations!
The sun has stopped.
The time was short, but it did stop!
No, it was the light of the sun that was left behind.
This mountain is a mythical mountain. It has a long sunshine time and cannot be inferred by common sense. She had some ideas in her mind, but she needed further confirmation. She suddenly became very happy because this mountain is magical.
Mountain, it contains countless treasures.
As a master of geography, it is natural that he should establish an observation station here.
Yuzai entered Zhu's world, and what came face to face was still the ancient and distant illusory land, but due to the influence of the two suns, the desolate world was no longer desolate!
Yanzai began to simulate the changes of the sun throughout the day. The last time he became a great shaman-level qigong master, Yanzai had already simulated it. After Heng Yang died, the sun rose and everything revived.
From death to life.
In Zhu's world, in the call of the sun approaching the heaven and earth, the two suns, Heng Yang and Chaoyang, actually began to overlap and merge!
Afraid of the order of the heavens and the times, I will march westward with my radiant spirit!
Yu Zai felt the change. The two suns merged into the sun totem and changed into one. Then the day began to cycle over and over again, and the years began to migrate. Although this great power was still at the level of feeling and philosophy, Yu Zai could already
Touched to one and a half points.
The name of this kind of sun is called "Yao Ling"!
Different names represent different powers and meanings. Just like the red pine nuts talked about the types of rain, the Yellow Emperor also called out the names of various thunders in the south.
At this moment, another “sun” appeared!
When Yuan Zai saw the circle, he was a little surprised, because the sun totem was merging with Taiyuan at this time, so Yuan Zai woke up, looked at the outline of the sun that was about to leave, frowned, and wanted to give it a try.
, and drew Taiyuan against the sky!
It is a circle, the same circle as the sun!
The outline of the sun overlaps with Taiyuan!
In Taiyuan, both Hengyang and Chaoyang returned to their original nascent state, so in an instant, the Taiyuan phases in Yu Zai's hand suddenly dispersed, leaving an afterglow of flames and disappeared in an instant.
Yuzai was stunned for a moment, looked at his hands, and then touched his head.
Is there something wrong?
It seems that some experiments are still needed, but fortunately, there is indeed a reaction. This is a good start.
Yanzai conducted observations for a period of time, and after recording enough astronomical data, he began to practice again. On the contrary, Chisongzi became obsessed with the act of conducting astronomical observations.
Because Yu Zai built a "Galilean telescope"!
【Build a university near a mountain, allowing you to build an observatory!】
This kind of ancient telescope is easy to make, because Yu Zai has already pointed out the optical technology, Chong Hua has been equipped with glasses, and it was made by Yu Zai and Xiong Tao together.
Only a convex lens with a larger diameter and a larger focal length is needed as the objective lens, and a concave lens with a smaller focal length and a smaller diameter is needed as the eyepiece.
Use swim bladder glue and small grooves to assemble the two lenses, stick them in a hardwood tube, and then make a simple pedestal. Then a telescope that can see the mountains on the moon, the stars in the Milky Way, and the satellites of Jupiter is ready.
Made!
Yuzai made a copper tube for the sake of beauty and carved patterns of the sun, moon and stars on it. Chisongzi was completely fascinated by this "artifact". He got the ancient astronomical telescope and immediately began to search for the location of the Taiyi star.
