Today the school organized us to visit the Science and Technology Museum, I came to the school early in the morning, excited, I thought: I heard that the Museum of Science and Technology built a new exhibition hall bigger than before, but also added a lot of new scientific and technological facilities, and some of them can also be operated by hand, which is really interesting, this time I must have a good visit.
We came to the Science and Technology Museum, led by the teacher to the new exhibition hall, the teacher announced the dismissal, we screamed and shouted and rushed to the inside. Instead of visiting blindly, I read the tour brief and learned what was on each level before going on the tour.
First, I visit the first floor. The first floor has four main exhibition areas: machinery, materials transportation energy and aerospace technology. We learn what nano-nano technology and aligned atoms are all about on the first floor.
Next, I come to the second floor. The second floor has modern communication technology, virtual human reality, display technology, microelectronics technology, sensors, electronics and computer application technology.
Then I went to the third floor. The third floor could be considered the most interesting one. I was very interested in the third floor because there were several major exhibits in the third floor, including Environment, Life, High Voltage Discharge, Sound, Light, Electromagnetism, Brain Science and Mathematics, which were somewhat similar to the knowledge taught in our textbooks, so I was very interested in them. One of the exhibits is called "A Glimpse of Infinity". I think it is very good. It is an optical phenomenon. From the mirror, you can see endless repeated images. I gently turned the frame with my hand and found that the position of all the images changed accordingly, so I didn't understand what was going on, so I asked the science teacher who was visiting. Science teacher told me: "This is a piece of two plane mirrors composed of reflection imaging optical system. In front of a semi-transparent half-reflective mirror, behind a fully reflective mirror, the two mirrors are in parallel position, with a number of reflective imaging characteristics, such as in the middle of them to put an object, you can reflect many images, when turning the frame to change the angle of the two mirrors, due to changes in the angle of incidence of the light, so the position of the reflected image also changes." After listening to my science teacher's explanation, I instantly understood the reason for this phenomenon. I was happy that I had understood a physical phenomenon.
As I walked on, I saw a sign that said "Tilt Hut". My curiosity led me there, and I saw people coming out of the hut, all tilted and dizzy. I wondered, "It's just a tilted hut, why would it be like this? I walked in with a disdainful mood, who knew that just inside, I hit a wall, knocked me out of my eyes for a while to slow down. Upon closer inspection, I realized that the house was very unusual, high on one side and low on the other, and it was on the low side that I had crashed. I carefully walked forward, but my body always involuntarily fell to the low side, every step is very difficult. I thought: there should be a sign here describing this cabin. So I slowly leaned against the wall and looked around. Sure enough, an introductory sign was hanging on the opposite wall, and I made a strong dash for it, grabbing hold of one of the railings and quickly looking at the description. But before I saw a few words, I let go and fell back to the lower wall. At that moment, I saw another ball on the opposite side resting on one end of a specific circle of track, and on the high end, and I wondered: could it be that there were magnets on that end? I rushed up once more, quickly read the instructions, and finally understood: the inclination of this circle of track with respect to the flat ground is in the opposite direction to the inclination of the hut's put, so we see that the ball stops at the high end, which is actually a visual error.
And finally, after seeing the four floors of the exhibition of ancient Chinese technological achievements, we were on our way home.
Sitting in the car on the way back, I thought: today I went to the Science and Technology Museum, I learned a lot of scientific knowledge, in the past I think it is impossible to have things, and many people think it is impossible to realize things, are now realized, can see how advanced science and technology now. Although I am still only a middle school student, can only visit other people's inventions, but I must study hard, and in the future, they invented more advanced high-tech products, benefit the society.
