Huang Tianxiang is a senior reporter and full-time reader of Beijing News Group.
President of China Science Popularization Association, President of National Evening News Science Popularization Editors Association, President of Beijing Science and Technology Journalists Editors Association, and member of the Reading Section of Beijing Press and Publication Bureau. He has served as the head of the science popularization section of Beijing Evening News and the director of the science and education department of Beijing Evening News for a long time, witnessing the whole process of the development and change of China media science popularization and science and technology reporting after the reform and opening up. Main works: The illusion of the sunset has been included in the junior high school textbook (the first volume of grade eight) The Illusion of the Sunset (selected from the sixth issue of Science and Life 1982), with slight changes. ) Science and Life People in Huang Tianxiang love to watch the sunrise and admire the spectacular sight when the sun rises. However, for the sunset, few people stay to watch and chant. What is the reason? I'm afraid it's emotional influence. "The sun is dying." Didn't even our ancients leave a poem "to see the sun, for all his glory, buried by the coming night"? In fact, the sunset is as spectacular, beautiful, mysterious and charming as the sunrise. If you have a chance to watch the sunset, it will fascinate you: the sun lies quietly on the western horizon, becoming so big and the color is so deep yellow and red; It descends slowly, contracting and flattening as it approaches the horizon. If there are clouds in the sky, you will see a brilliant sunset; There are no clouds all day. Don't forget to look back. You will find a mysterious blue-gray dark arc in the sky behind you, and there is an obvious bright arc outside the dark arc. While the dark arc and the bright arc rise, charming purple light will appear in the western sky. As the sun goes down, the purple light moves down and disappears when it approaches the horizon. Unfortunately, this beautiful purple light is rare. The sunset is really beautiful, colorful and unpredictable. However, the audience will not think that most of these strange scenes are illusions, and the sunset itself has not changed. Astronomers have long discovered that the earth's atmosphere scatters light. 187 1 year, British scientist Rayleigh proved that the scattering of short-wave light is much stronger than that of long-wave light. Therefore, the intensity of short-wave light-violet light scattered by tiny dust and air molecules in the atmosphere is more than 10 times that of long-wave light (which can explain why the sky is always blue). Because at sunset and sunrise, the atmosphere penetrated by sunlight becomes thicker, and yellow and red light have the greatest penetration ability, so the sun at this time looks dark yellow and crimson. Generally speaking, there is more smoke and dust in the air at dusk than in the morning, so the color of sunset is different from that of rising sun. Because the earth's surface and atmosphere are curved, the distance of the sun's light passing through the atmosphere near the horizon is much longer than that of the upper layer, so the light entering the bottom layer decays quickly, and the shadow of the earth caused by the sun sinking into the horizon appears blue-gray dark arc in the sky; However, the upper atmosphere has a low density and weak light scattering, which leads to a bright arc on the dark arc. This wonderful atmospheric optical phenomenon rises to the zenith with the setting of the sun and disappears with the arrival of darkness. As for the beautiful purple light, it is caused by the superposition effect of human eyes, which makes the red light passing through the atmospheric dust overlap with the blue scattered light of the purer air in the upper atmosphere. The illusion that the sun is flat appears not only at sunset, but also when the sun jumps out of the horizon. This is because when light passes through the air, the speed slows down by 87 kilometers per second, so the refraction of light changes accordingly. Therefore, when the lower edge of the sunset touches the horizon, the ratio of the height to the width of the sunset is 26.5 ∶32 through refraction, and the sun in the eyes of the viewer is naturally flat. The most puzzling illusion is that the sun at sunset looks two and a half to three and a half times bigger than it did at high altitude, just like a huge jade plate hanging in the distance of the horizon. But in fact, astronomers outside the atmosphere have used various instruments, including cameras, to prove that the sun at dusk is the same size as the sun at noon. The Illusion of the Sunset is an extracurricular anthology. This article is a popular science article, explaining in scientific language that the beautiful sunset in people's eyes is actually an illusion, inspiring people to treat everything around them with scientific spirit, so that everyone can raise their heads and seek the truth of everything at this secular moment.

In the book "The King of Wu", he is a general of the Western Zhou Dynasty and the son of King Huang of Wu Cheng.
In the list of gods, he was named the highest day star. The greatest super warrior in martial arts can't do it, but he is the only one among the gods who defeated the immortal with mortals. Although he was defeated by witchcraft in the end, his brilliant record of killing LAM Raymond, doing well and defeating Qiu Yin has proved his existence value as the first military commander in Zhou Ying.
