Welcome! Today we are going to look at the motion of the sun with part 7 of chapter 3. First of all, our question is, is the earth standing still while the sun is moving around the earth? This question is closely related to the topic of today's lesson. Let's get started. The content of today's lesson is divided into two parts. The first is the motion of the sun and the second is the phenomenon of the sun rising and setting. We come up with two examples. That is, when we are driving and when we are spinning, are all the objects around us moving or are we moving? Because when we are driving or spinning, the objects around us run around. The question is, are the objects around us moving or are we moving? All of us know that the sun rises in the east and sets in the west. So is it really because the sun is moving or is it because of our movement that there is such a difference? The answer is, it is because the earth rotates itself, so we have the phenomenon of the sun rising in the east and setting in the west. The earth rotates itself according to the trend from the west to the east, so there is the phenomenon of the sun rising in the east and setting in the west. So our answer is, it is because the earth rotates, so we have the difference between the times we see the sun. And we have to pay attention to the two concepts, that is, the real movement and the visible movement. In this case, we see the sun rising in the east and setting in the west. That is our visible movement. And the real movement is the rotation of the Earth from the west to the east. That is also the reason for the phenomenon that when noon comes, the sun rises the highest above the earth. And when evening comes, the sun rises in the east. And in the morning, the sun rises, just like that, one more cycle. The Earth rotates around itself and rotates around the sun with an elliptical pattern. So we have the phenomenon of long, short days and nights, between different months, like in the poem, the day has been lighted up in May, and the day has not been darkened in October. In short, the phenomenon of day and night always occurs on the earth because the earth is illuminated by the sun and the rotation of the earth's rotation. That is also the cause of the phenomenon that we see the sun rising in the east and setting in the west. Expanding on today's lesson, have you ever heard of the quantum mechanics or quantum mechanics? Quantum mechanics tells us that the earth stands still and the earth is the center of the universe. The quantum mechanics says that the sun is the center of the universe. And now we all recognize that the sun is the center of the universe and other planets revolve around the sun, because the earth rotates around its axis. But before that, people thought that the earth was the center of the universe. And the first person to lay the groundwork for quantum mechanics, that is, the sun is the center of the universe, was Nicholas Cormac Meekus, born in 1173 and died in 1543. At that time, this idea of ​​his was not accepted by everyone, and it was considered to be illogical and sinful. Continuing this idea of ​​Cormac Meekus, Galileo Galilei, born in 1564 and died in 1642, also affirmed that the sun is the center of the universe and was not recognized by everyone. He has a very famous saying, that is, no matter what, the earth will still rotate. He said that when he was condemned for believing that the sun was the center of the universe, he was angry and went to court with the saying, no matter what, the earth will still rotate. Today's lesson is over. We remember two things. The first is the transformation of the sun's vision, the distinction between the transformation of vision and the transformation of reality. The second is the phenomenon of the sun rising and setting.
