/kloc-a venetian businessman in the 0/5th century often went out to do business, but he was worried that his wife would go out to have an affair. One rainy day, he was walking in the street, with a lot of mud on his heels, and he walked very hard. Businessmen are inspired by this, because Venice is a water city and boats are the main means of transportation. The businessman thinks that his wife will not be able to walk on the springboard in high heels, so she can be trapped at home.
Unexpectedly, his wife felt very novel when she put on these shoes. Accompanied by the servant, she got on and off the boat and played around. High-heeled shoes made her more graceful, and fashionable ladies rushed to follow suit, so high-heeled shoes quickly became popular.
raincoat
1747, French engineer Franois Fraineau made the world's earliest raincoat.
He used latex obtained from rubber wood to dip cloth shoes and jackets in this latex solution, which can play a waterproof role.
McIntosh, who works in a rubber factory in Scotland, can't afford rain gear because he lives in poverty. Every rainy day, he can only go to work in the rain. One day, he accidentally spilled rubber juice on his clothes and couldn't wipe it off, so he had to wear this dirty clothes to go home. It was raining outside, but when McIntosh came home, he was surprised to find that his clothes were not wet at all. He just smeared rubber juice on his clothes. This is the first rubber raincoat in the world.

1828 sheffield made a single-sided protection blade, which is the predecessor of the safety blade.
1895, an American salesman, Gillette, stumbled upon the inventor painter, hoping to make a lot of money and invent something that everyone needed once.
One day, Gillette shaved and found that the razor blade just met this idea. He designed a safe razor handle, but he couldn't find a manufacturer who could make thin blades. It was not until 190 1 that he met Carson, a mechanic, that he solved the technical problem, combined the hoe rest with the double-edged replaceable blade and applied for a patent.
As early as 1900, the electric shaver was patented in the United States, but the first electric shaver suitable for commercial manufacture was designed by retired American army colonel Hick and patented in 1928.

Our ancestors made beautiful "transparent mirrors" more than 2000 years ago. /kloc-At the beginning of the 4th century, Venetians painted tin foil and mercury on the back of glass to make mirrors, which looked very clear. /kloc-The convex lens made in Nuremberg in the 0/5th century was made by coating a layer of mercury in the glass.
Modern mirrors are made by the method invented by German chemist Libiger in 1835. Silver nitrate is mixed with reducing agent to precipitate silver from silver nitrate and attach to glass.
Traction chain
Zipper was first invented by Chicago mechanic Judson in 189 1 year.
In order to relieve the trouble of tying shoelaces every day, Judson invented a zipper which can replace shoelaces. This zipper consists of a row of hooks and a row of buttonholes. Pull an iron slider from bottom to top, and the hook and buttonhole can be fastened one by one. Judson sent the sample to Columbia Expo on 1893, which was well received and patented.
Nowadays, there are more and more kinds of zippers, and their applications are not limited to daily necessities, but also enter the fields of scientific research, medical care, military affairs, etc., and are praised by some as one of the 10 great civilizations in the field of science and technology in the 20th century.
fridge
The first artificially compressed poplar was invented by Harrison at 185 1. Harrison is the owner of Quilen advertising company. When he cleaned the type with ether, he found that ether had a strong cooling effect on metals.
Ether is a liquid with low boiling point, which is easy to evaporate and absorb heat. Harrison developed a refrigerator using ether and pressure pump through research, and applied it to a brewery in Victoria, Australia, for refrigeration and cooling during brewing.
The first refrigerator with motor-driven compressor 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 at 1925.
Edison, the king of invention
Telegraph, telephone and electric light are so common and common in today's advanced technology that no one will be surprised. But do you know how important these things were to people at that time and how ecstatic they were? Humans thus remembered their inventor-Edison.
Edison, known as the "King of Invention", is a famous American scientist and inventor. In his life, there were 1328 inventions registered in the patent office alone. How can a person who has only studied for three months have so many inventions? I think, if you have heard the story of "Edison incubating chickens", you will understand that his success stems from strong curiosity.
1847, Edison was born in a merchant family in Milan, Ohio, USA. Edison showed great curiosity when he was very young. Whenever he sees something he doesn't understand, he grabs the adult's skirts and keeps asking questions, insisting on asking ugly questions.
One day, he pointed to the hen that was hatching eggs and asked his mother, "Why is the hen sitting under her ass?" Mother said, "Oh, that's a chicken!" " "In the afternoon, Edison suddenly disappeared, and the family was anxious to look around and finally found him in the henhouse. It turned out that he was squatting in a chicken coop with a lot of eggs under his ass to hatch chickens! When his parents saw it, they were so distressed that they had to pull him out and wash his face and clothes. Another time, when he saw birds flying freely in the sky, he thought: Since birds can fly, why can't people fly? So, he found a kind of powder for his friends to eat, in order to let them fly into the sky. As a result, the little friend almost died, and Edison was severely beaten by his father.
Finally, Eddie grew up to 8 years old, and his parents sent him to a rural primary school, thinking that he could go to school safely from now on. Who knows, he still loves to get to the bottom of it, and often asks 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 is 2 plus 2 equal to 4?" This question puzzled the teacher. He thinks Edison is a troublemaker and always disagrees with his teacher. So Edison attended classes for three months and was driven home by the teacher.
Edison's mother is a great mother. She didn't blame her only son for being driven back. Instead, he decided to educate the child himself. When she found Edison curious and particularly interested in physics and chemistry, she bought him books about physics and chemistry experiments. Edison started the experiment on his own according to books. It can be said that this is Edison's enlightenment education in scientific inventions.
When he grew up, Edison learned radio transmitting and receiving technology. He got a job as a night shift operator at Stratford Railway Sub-bureau. According to the regulations, the night shift operator must send a signal to the train service director every hour after 9 pm, no matter what happens. In order to have a good rest at night and study and invent during the day, Edison designed a telegraph that can automatically send signals on time. This is the prototype of the telegram.
Soon after, he improved the telegraph. After many tests, a new type of telegraph was successfully trial-produced. Edison looked at the machine he invented and smiled with relief.
It should be said that every invention of Edison is closely related to his curiosity. After inventing the telegraph, he began to do telephone experiments. He found that the diaphragm in the microphone could vibrate with the sound, so he observed it carefully and made a detailed record in his notebook. Thus, a "talking machine" was made. 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 his wisdom.
Not only famous scientists need curiosity, but we ordinary people also need curiosity to learn knowledge and achieve something. 199 1 In July, Guangming Daily Science and Technology Department conducted a questionnaire survey on 1 18 middle school students who won the National Youth Science and Technology Invention Competition. In the column of "Your main psychological characteristics", 92% of the students wrote "Strong curiosity". He Ji, a teenager from No.1 Middle School in Daoxian County, Lingling District, Hunan Province, couldn't help wondering when he went to the henhouse to get eggs one day: How can eggs be big or small? Is the big head first out of the matrix or the small head first out of the matrix In order to find out this problem, he rushed home immediately after school every day, squatted by the chicken shed and observed quietly, sometimes even forgot to eat dinner. After more than two months, He Qi finally found that the egg came out first. To this end, he wrote a paper, which was praised by many biologists. His discovery is actually a new discovery that has not been recorded in bird literature.
Being a talent requires curiosity, but being curious doesn't mean that you will become a talent. If you want to achieve something, you still need to work hard. Curiosity is like a seed. Without it, a towering tree cannot grow, and people without curiosity cannot invent or create anything. After the seeds are sown in black soil, they will gradually break through the soil and grow into pillars through watering and cultivation. With curiosity, sweat and hard work, you will certainly become a useful talent. Dr. Li Zhengdao, a famous contemporary physicist, said: "Curiosity is very important, and curiosity is indispensable for science. The reason is very simple. Only curiosity can ask questions and solve problems. The terrible thing is that you won't ask questions and take the first step. " Because curiosity is so important, many people call it the first virtue of successful people. For an ambitious and eager teenager, curiosity is the most precious thing.
Both the story of Edison, a great inventor, and the story of He Ji, a middle school student, have proved a truth to us: curiosity-the heart of an inventor.
Do you long for your flower of wisdom to bloom soon? Are you eager for your creative inspiration to come soon? Then, observe life carefully! A person who does not love life and is indifferent to everything around him will not have a curious heart. If you want to be a bright star on the future life stage, take the first step of your success from now on-enhance your curiosity!
