The Earth we live on is a planet in the solar system. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info While it revolves around the sun, it rotates itself from west to east. It's just that because we live on top of it, we can't feel its rotation. This is common knowledge that we already know in elementary school. Whenever I think about it, I always regret not being able to see the rotation of the planet we live in.

One summer, on a clear night. I sat in the open space in front of my house to cool off. Looking up at the starry sky, I couldn't help but think of this question again: "。。。。。。 It's just that they rotate with it, so you can't feel it moving. Then he thought, "If we leave the earth and go to the sky, we can see the earth spinning." "But even though the astronauts have gone to the sky, I can't do it yet. Suddenly I thought, "The stars in the sky are immovable relative to the earth." If we choose a star in the sky as a reference object and compare its position with that of an object on the ground, then we should be able to see that the earth is moving under our feet. ”

It just so happened that there was a four- or five-meter-high electric pole not far in front of me, which had long been abandoned and was smooth without any obstruction of vision. I thought, "If I stand on the east side of the pole and let my eyes look at the stars in the western sky through the top of the pole." When my eyes, the tip of the pole, and the stars become a line, both me and the pole will move with the earth as it rotates from west to east. And the stars are immobile relative to us, so if I stand on the east side of the pole, I will see the stars disappear behind the pole.

With that in mind, I got up and walked to the east side of the pole. In the western sky, a star was chosen that was closer to the top of the pole. I started walking back and forth, adjusting my position. Let your eyes pass through the top of the pole and just see the star. As soon as my eyes passed through the top of the pole and formed a straight line with the star, the star immediately disappeared behind the pole. I had to go backwards right away to keep my eyes on the three-point line between the top of the pole and the stars. However, as soon as I adjusted my position, the star disappeared behind the pole again. I hurried back away, and the stars disappeared again. So I retreated, and the stars disappeared again。。。。。。

In the midst of continuous regression, I suddenly noticed that the pole in front of me was moving. Then, I saw that the buildings around me were also moving. Finally, I saw the earth moving beneath my feet. Ahh。。。。。。h

I finally saw the earth spinning. And it's spinning just too fast. If it weren't for this experiment, I wouldn't have known that our time would have passed so quickly. How can we waste our time and not cherish it?

That night has been etched in my memory ever since. Because on that night, I not only saw the earth spinning, but also got a little precious revelation from life. Now whenever I encounter difficulties, I always say to myself, "Think about it, there will be a solution." As long as you are willing to use your brain, you can see the earth rotate when you stand on the earth!"
