Dust Travels clip:
Dust is the never-tireless traveler on Earth, and it drifts with the turbulence of the air.
The air around us, from indoor to outdoor, from the city to the countryside, from the flat land to the mountains, from the desert to the ocean, has its whereabouts almost everywhere. A truly dust-free space can only be made in a laboratory.
Under a clear sky, the dust is invisible, and only when the sun's rays shine through the cracks in the blinds into the dark room, countless dusts can be clearly seen floating in the air. Large dust can be seen with the naked eye, but small dust is smaller than bacteria, and even ...... cannot be observed with a microscope

Hello dear, the overall book of "Dust Travel" includes three parts: first, scientific fairy tales, including "My Name", "My Hometown", "My Family Life", "Water Country Travel", etc.; the second is scientific essays, including "The Seven Periods of Life", "The Clothing, Food, Housing and Transportation of Bacteria", "The First Lesson of Bacterial Forest Learning", etc.; The third is the plain expository essays, including "Huizhen Talks about Glasses", "Temperature and Thermometer", etc. Gao Shiqi is a well-known microbiologist, popular science writer, poet, educator and social activist in China.
Gao Shiqi's life can be described as "legendary", graduated from Tsinghua University at the age of 20, and entered the Department of Chemistry of the University of Wisconsin in the same year (1925). In 1928, he was infected with the A encephalitis virus while doing experiments, leaving sequelae. In this extremely difficult situation in the previous spring, he resolutely returned to China, ran around for the medical cause of the motherland, and wrote a large number of popular science articles, "Dust Travel" is one of them.
Gao Shiqi has devoted his life to the popularization of science and the creation of children's books, and his representative works include "The Autobiography of the Fungus", "The Plague is Coming", "The Aspects of Disease", etc., leading readers to easily enter the world of science and unveiling the mystery of science for us.

The travel knowledge points of dust are as follows:
Bacteria travel in the air and have a great influence on meteorological changes. It turns out that bacteria are also small engineers who create clouds and raindrops, and they will help the moisture in the air to condense into clouds and raindrops.
Without them, there would be no white clouds, no heavy rain and light rain, and without them, in the summer, strong daylight would shine directly on the earth, making it impossible to lower the temperature. This is the function of bacteria in nature.
Bacteria are natural from the debris of mountain rocks, dry soil from fields, salt powder from the sea after evaporation of waves, volcanic ash, and cosmic dust from interstellar space.
Dust can be seen with the naked eye, and small ones cannot be observed with a microscope. Natsu dust has a lot of effects on weather changes. It is the little engineer who makes clouds and raindrops, without which there are no white clouds and rain.
In summer, it can block out daylight and rain low temperatures.
Bacterial hazards
Bacteria are the destroyers of the respiratory tract, they can cause nostrils to obstruct, cracked eggplant to change trachea inflammation, lung damage and cause colds, epidemics, pneumonia and other infectious diseases. In addition, bacteria from metals, especially lead, can poison people; Lime and cement bacteria can damage our lungs and corrode our **. In these cases, in order to resist the attack of germs, we must wear a mask or mask.
