What are some stories about scientific inventions?

High heels\x0d\A Venetian businessman in the 15th century often had to go out to do business, and he was worried that his wife would go out to have a romantic affair. One rainy day, he was walking on the street, and the heels of his shoes were stained with a lot of mud, so he had difficulty walking. The businessman was inspired by this, because Venice is a water city and boats are the main means of transportation. The businessman believed that his wife would be unable to walk on the springboard if she wore high heels, so he could trap her at home.\x0d\Unexpectedly, his When my wife put on these shoes, she felt very novel, so she was accompanied by a servant, boarding and disembarking, and playing everywhere. The high heels made her more graceful, and fashionable ladies followed suit, and high heels quickly became popular.\x0d\ Raincoat\x0d\In 1747, French engineer Fran?ois Freno made the world's earliest raincoat.\x0d\ He used latex obtained from rubber wood and soaked cloth shoes and coats in this latex solution. After coating, it can play a waterproof role.\x0d\In the Scottish rubber factory, McIntosh was in a difficult situation and could not afford to buy rain gear. Every rainy day, he could only commute to get off work in the rain. One day, he accidentally removed the rubber The juice was all over his clothes and pants, and he couldn't wipe them off, so he had to wear the dirty clothes and go home. It was raining outside, but McIntosh came home and was pleasantly surprised to find that the clothes he was wearing were not wet at all. He simply wiped the rubber juice away Cover your entire body. This is the world's first tape raincoat.\x0d\Razor\x0d\In 1828, Sheffield made a blade with one side protected, which was the predecessor of the safety blade.\x0d\In 1895, the United States Gillette, a salesman, met the inventor Painter by chance. He wanted to make a lot of money and invent something that everyone needed and could be used once.\x0d\One day, Gillette was shaving and found that the razor blade was exactly the same. Suitable for this idea. He designed a safety razor holding handle, but could not find a manufacturer that could make a thin blade. In 1901, he met the machinist Carson and solved the technical problem, making the hoe-shaped tool holder and The double-edged replaceable blade was integrated into one and patented.\x0d\ As early as 1900, the electric razor had been patented in the United States, but the first commercially manufactured electric razor was invented by a retired U.S. Army colonel. Designed by Sigg and patented in 1928. \x0d\Mirror\x0d\ Our ancestors made exquisite "translucent mirrors" more than 2,000 years ago. In the early 14th century, the Venetians used tin foil and mercury to coat Mirrors are made on the back of the glass to see clearly. Convex lenses were made in Nuremberg in the 15th century. They were coated with a layer of mercury inside when making the glass. \x0d\ Modern mirrors were invented by the German chemist Liebig in 1835. It is made by mixing silver nitrate and reducing agent to precipitate silver from the silver nitrate and attach it to the glass.\x0d\Zipper\x0d\The zipper was first invented by Judson, a Chicago machinist in the United States in 1891.\x0d\Judson To relieve the trouble of tying shoelaces every day, we invented a zipper that can replace shoelaces. This zipper is composed of a row of hooks and a row of buttonholes. Use an iron slide to pull up from bottom to release the hook. Fasten them one by one with the buttonholes. Judson sent the sample to the 1893 Columbian Exposition for display, which was well received and obtained a patent. \x0d\ Today, the types of zippers are increasing, and their applications are not limited to daily necessities, but also have entered the market. In the fields of scientific research, medical treatment, military and other fields, it has been hailed by some as one of the ten major civilizations in the scientific and technological world of the 20th century.\x0d\Refrigerator\x0d\The first artificial refrigeration compressor was invented by Harrison in 1851. Sen is the owner of Australia's Geelong Advertiser. When he used ether to clean lead type, he found that ether had a strong cooling effect when applied to metal.\x0d\Ether is a liquid with a low boiling point and it evaporates easily. Endothermic phenomenon. After research, Harrison developed a refrigerator using ether and a pressure pump, and applied it to a brewery in Victoria, Australia, for cooling and cooling during brewing.\x0d\The first compressor to be driven by an electric motor The machine-operated refrigerator was invented by Swedish engineers Brighton and Mendes in 1923. Later, an American company bought their patent and produced the first batch of household refrigerators in 1925.\x0d\"The King of Inventions" Eddie

Production\x0d\Telegraphs, telephones, electric lights, these things are so common and commonplace in today's technologically advanced world, no one will be surprised by them. But you know how crucial and commonplace these things were to people at that time Are you ecstatic? Human beings have remembered their inventor - Edison. \x0d\ Edison, known as the "King of Inventions", is a famous American scientist and inventor. In his life, he only patented There are 1,328 inventions registered by the Bureau. How could a person who had only been educated for three months have so many inventions? I think if you have heard the story of "Edison hatching a chicken", you will definitely understand. , His success stems from strong curiosity.\x0d\In 1847, Edison was born in a business family in Milan, Ohio, USA. When he was very young, Edison showed a strong curiosity. As long as he saw If he didn't understand something, he would grab the hem of the adult's clothes and ask him non-stop, insisting on asking about the Chou Yinmao.\x0d\One day, he pointed to the hen that was hatching eggs and asked his mother: "The hen takes the eggs." What are you doing sitting under your butt?" Mom said, "Oh, that's hatching chicks!" In the afternoon, Edison suddenly disappeared. The family looked around anxiously and finally found him in the chicken coop. It turned out that he He was squatting in the chicken coop, with many eggs under his buttocks to hatch chicks! After his parents saw it, they couldn’t laugh or cry, so they had to pull him out, wash his face, and wash his clothes. Another time, he saw the bird The boy was flying freely in the sky, and he thought: Since birds can fly, why can't people fly? So, he found a kind of medicinal powder for his little friend to eat, in order to make the little friend fly into the sky. As a result, the little friend almost died. , Edison was also beaten severely by his father. \x0d\ Finally, when Edison reached the age of 8, his parents sent him to a rural primary school, thinking that from now on he would be able to go to school safely. Who knows, he He still loved to get to the bottom of things, and often made the teacher dumbfounded and embarrassed. Once in an arithmetic class, the teacher wrote "2 2 = 4" on the blackboard. Edison immediately stood up and asked: "Teacher, why does 2 plus 2 equal Where is 4?" This question stopped the teacher. He thought Edison was a troublemaker who was specifically trying to get into trouble with the teacher. So, after three months of classes, Edison was driven home by the teacher.\x0d\Edison's My mother was a great mother. She did not blame her only son for being driven back. On the contrary, he decided to educate the child well by himself. When she discovered that Edison was very curious and particularly interested in physics and chemistry, she bought him some related books. Books on physics and chemistry experiments. Edison followed the books and started experiments alone. It can be said that this was Edison's enlightenment education for scientific inventions.\x0d\When Edison grew up, he learned the technology of sending and receiving radio messages. The Tradford Railway Branch found a night shift operator job. According to regulations, night shift operators must send a signal to the train director once every hour after nine o'clock in the evening, regardless of whether they have something to do or not. In order to have a good night's rest, Edison could After studying inventions and creations, he designed a telegraph machine to automatically send signals on time. This was the prototype of the telegraph machine.\x0d\Not long after, he improved the telegraph machine. After many tests, a new type of telegraph machine was built. The trial production of the machine was successful. Edison looked at the machine he invented and smiled happily. \x0d\ It should be said that every invention of Edison is closely related to his curiosity. After he invented the telegraph, He began to experiment with telephones again. He discovered that the diaphragm in the microphone could vibrate in response to the sound of speaking. He observed it carefully and made detailed records in his notebook. From this, a "talking machine" was created. When people heard the news, they all came to watch and called him "the greatest inventor". Therefore, curiosity is a prerequisite for a person to succeed and show wisdom. \x0d\ Not only famous scientists need curiosity , we ordinary people also need curiosity to learn knowledge and achieve success. In July 1991, the Ministry of Science and Technology of "Guangming Daily" conducted a questionnaire survey on 118 middle school students who won prizes in the National Youth Science and Technology Invention Competition. In the column "Psychological Characteristics", 92 students wrote "strong curiosity". He Ji, a teenager from Daoxian No. 1 Middle School in Lingling Prefecture, Hunan Province, couldn't help but wonder curiously when he went to the chicken shed to collect eggs one day.

Dao: Why are eggs big on one end and small on the other? Does the big head emerge from the mother's body first or the small head first? In order to find out this problem, he rushed home as soon as school was over every day, squatted next to the chicken shed and observed quietly. Sometimes he even forgot to eat dinner. More than two months later, He Ji finally discovered that eggs emerge from the mother's body with the big head first. To this end, he wrote a paper and was praised by many biologists. His discovery turned out to be a bird New discoveries that have not been recorded in such literature.\x0d\Being successful requires curiosity, but having curiosity does not mean that you will be successful. If you want to be successful, you need to work hard. Curiosity is like a A seed. Without seeds, towering trees cannot grow. People without curiosity cannot invent or create anything. After the seeds are sown in the black soil, they will gradually break out of the soil after being watered and cultivated by people. From a seedling to a pillar, curiosity, coupled with sweat and hard work, will definitely make you a useful talent. Dr. Li Zhengdao, a famous contemporary physicist, said: "Curiosity is very important, and it is indispensable for science. Curiosity. The reason is very simple. Only curiosity can ask questions and solve problems. The terrible thing is that you can't ask questions and can't take the first step. "Because curiosity is so important, many people call curiosity a winner." The first virtue. For a young man who is aspiring to become talented and eager to succeed, curiosity is the most precious. \x0d\ Whether it is the story of the great inventor Edison or the story of primary and middle school student He Ji, they all prove to us a Truth: Curiosity - the heart of the inventor.
