In every corner of life, science was everywhere. It was like a magical key that opened the door to a better life. Students, have you ever thought about the reason why the bird sleeps in the tree but does not fall? Why did Yan Qianniao brush the crocodile's teeth? How could a pigeon become a postman? Such questions are waiting for us to explore and find answers, and this process of exploration and search is science.
We all have this experience. The air after the rain is fresh and pleasant, and the sky is clear and clear. Especially at dusk after the rain, there will occasionally be beautiful rainbows in the sky. So how did the rainbow form? This requires us to discover, explore, and research. In fact, the process of constantly digging, breaking through, and surpassing common sense was exploration, which was also science.
Once, my parents took me to visit the Youth Science and Technology Museum. The rich scientific knowledge in the museum opened my eyes. As soon as I entered the hall, I was attracted by the scene in front of me and hurriedly ran over to investigate. It turned out to be a row of devices that displayed bird eyes, fish eyes, and insect eyes. I first looked at the world through my bird's eyes and found that everything had turned green. This was really amazing. Not only could my bird's eyes see things during the day, but they could also see at night. Then, he looked at the fish eyes. What it saw was the same as what the human eye saw, but its eyes could magnify the objects it saw. The fish eyes could discover microorganisms that the human eye could not see. Finally, the insect's eyes looked like countless mirrors reflecting the scene in front of them. It was dazzling. Upon closer inspection of the insect's eyes, one would discover that they were two large eyes made up of many small eyes. These were the so-called compound eyes. When insects were flying, they could quickly find food or enemies in front of them with their compound eyes, just like the big round eyes of dragonflies. The world in their eyes was so unique.
This visit made me secretly determined to study hard and become a scientist in the future. I will invent many useful things for mankind and make our lives better.

MemorialThe memorial was one of the documents that the officials submitted to the emperor during the Ming and Qing Dynasties. In the early Ming Dynasty, the subjects used memorials to the court. After the reform in the twenty-second year of Yongle, the title book and the memorial book were used concurrently. Officials used the title book for official business and the memorial book for private affairs. The Qing Dynasty followed the system of the Ming Dynasty, but the use of memorials was limited to officials, such as the appointment of officials, promotion, promotion, record, exemption, punishment, or dismissal of officials, special gifts, gratitude on behalf of officials, etc., all used memorials. At the beginning of the Qing Dynasty, it was stipulated that the number of words in memorials should not exceed 300 words, and the number of words and paper should be indicated at the end of the text. After the 13th year of Qianlong, it was abolished and used for public and private affairs.

Sharpness in photographySharpness in photography was a physical measurement used to measure the quality of the edge of a picture. It could also be called "definition." The quality of the edge was related to the definition perceived by the human eye. It was an indicator of the clarity of the image plane and the sharpness of the edge of the image.
From the perspective of imaging, sharpness described the speed at which the image information at the border transitioned. The transition speed of high contrast was fast and could form a clear edge, while the transition buffer existed in low contrast, and the image edge was blurred. The sharpness could be judged by the clarity of the edges and details of the objects in the picture. The higher the sharpness, the clearer the details of the picture. On the contrary, the picture was blurry, the details were not expressed enough, and the edges were not coordinated with the picture.
Sharpness was related to contrast. The higher the sharpness, the higher the edge contrast. Increasing the edge contrast would also increase the sharpness. The "sharpening" function in the image processing software used this principle.
In photography, different scenes had different requirements for sharpness. When shooting a landscape, one often pursued sharpness to obtain a sense of déjà vu. However, when shooting a portrait, too high sharpness would cause particles to appear on the skin of the character, magnify small skin flaws, and even cause white edges to appear on the edges of the face, hairline, eyebrows, eye sockets, nose, lips, and other black and shadow parts, affecting the image effect.
In addition, there were other factors that would affect the sharpness of the photo. In terms of lenses, the sharpness of a fixed-focus lens was generally higher than that of a zoom lens. Because of the large number of lenses in a zoom lens, it was more difficult to design, and it was easy to produce optical aberrations. Moreover, the large number of lenses would reduce the contrast and increase the facula. The fixed-focus lens usually had a larger aperture than the zoom lens. Under the same circumstances, the sharpness of a large-aperture lens was higher than that of a small-aperture lens. In terms of shooting operations, use a high-speed shutter when shooting with a hand-held camera, stabilize the camera to reduce shaking, use a low sensitivity to reduce noise, and focus correctly to make the subject clear.(Automatic focus is convenient and practical, and manual focus can achieve better control when shooting speed is not required), adjusting the photo style to increase the sharpness (can be directly set in the camera photo style), using a wide-angle lens to shoot scenery (large depth of field, large front and back clear range), long-distance shooting (the clear range of the focus can cover the background to make the picture clearer), etc. all help to improve the sharpness of the photo.
