Raincoat/KLOC-In the 0 ~ (th) century, MacIntosh, a rubber factory in Scotland, couldn't afford rain gear because of financial difficulties, and had to go to work in the rain every rainy day. 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.
Shaver 1828 Sheffield made a single-sided protective blade, which is the predecessor of the safety blade. 1895, an American salesman Gillette met an inventor and painter. Painter wants to make a lot of money and invent something that everyone needs and can use once. One day, Gillette was shaving, and painter found that razor blades were just right for 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.
Mirrors Our ancestors made beautiful "transparent mirrors" more than 2,000 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.
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.
Zipper 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 and so on, and are praised by some as one of the top ten inventions in the 20th century.
The first artificial refrigeration compressor in the refrigerator was invented by Harrison in 185 1 year. Harrison, the owner of Quilen Advertising, an Australian newspaper, found that ether had a strong cooling effect when used to clean type. 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 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.
Sonar is invented according to the positioning system of dolphins ~
2. According to the structure of the Bird's Nest, the main stadium tube (named Bird's Nest) of Beijing 2008 Olympic Games was built.
According to the inspiration of the chameleon's escape, people invented special military uniforms for different geographical environments.
Helicopters were invented by dragonflies.
Underwater dynamics was invented through the body of fish.
The invention of mankind-inspired by animals-ships and submarines came from people's imitation of fish and dolphins. Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose. The rocket takes off by using the recoil principle of jellyfish and squid. Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability. Scientists studied frog eyes and invented electronic frog eyes. The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes. Humans also used the principle of leapfrog to design a toad ram (hang). Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation.
Bionic and high-tech modern radar, a radio positioning and ranging device: scientists found that bat monsters rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bat magic emits ultrasonic waves when flying, it can also detect the ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device ... Scientists have invented an artificial dolphin skin that can improve the speed of torpedoes by studying the tiny swimming resistance of dolphins; And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert.
Inspired by King Penguin, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-"King Penguin" brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface and supported by a wheel spoon, and the driving speed can reach 50 km/h.
Scientists make space robots by imitating insects.
A research team of Australian National University has developed a small navigation and flight control device by studying several insects. This device can be used to equip a small aircraft for Mars exploration.
Inspired by bionics, British scientists are developing a new submarine, which can swim in an S shape by swinging its tail fin. The main innovation is the use of a device called "trunk actuator". "Elephant trunk" consists of a group of thin and soft hoses, which imitate muscle activity and promote fin movement. This new submarine can be used as an underwater mine-clearing submarine to deal with mines that will detonate under the slightest noise or interference.
Enlightenment of nature to human beings
Nature is beautiful, so we should protect it. We shouldn't throw rubbish, spit and cut down trees. Then, I will tell you a story.
Once upon a time, there was a village. He doesn't like to protect nature, so he cuts down trees and makes them into chairs and tables. Soon, everyone in the village felt that the house was old and should be replaced. People went to chop wood to build houses, and the houses were finished. People in the village there cried happily. Some people were very proud. Their houses were more beautiful than others. In this way, people cut down trees every day.
Soon the flood came and the village was completely destroyed by the flood. Even the most beautiful houses were washed away by the fierce flood, because some houses were washed away because of countless obstacles, and this place became a wasteland. This story is for everyone not to pick up the land indiscriminately.
Nature is so good, why would anyone want to destroy it? Let me talk! Because some people have nowhere to throw, they can't throw them underground. Some people think it's just a waste of garbage and no tutor. In our class, some people don't eat apples, but also draw pictures on them. Some people chew and spit on the ground, which makes life on duty very troublesome. In such a good environment, they learned to listen. The small bones of ants help us unite, while bees collect honey and teach us to work hard. Do you think nature is so beautiful that you are willing to destroy it?
The revelation of nature
The ancients had an extremely profound saying: Learn from nature. Great! Nature has indeed taught us many, many lessons, and each lesson is more exciting than the next. Listen to a story first.
Story 2: In order to dry clothes, someone tied wire to two trees not far apart. Over time, the iron wire formed an iron hoop and was firmly pulled into the trunk, leaving a deep impression on the tree. Two years later, the hoop was deeply pulled into the tree. The poor tree seemed doomed to death, but a miracle happened because of it. The tree didn't strangle, but stood up firmly and swallowed the terrible iron hoop alive! And all this happened to be seen by a desperate old man, and he summoned up the courage to live. The old man has cancer! He overcame his illness and survived. After living for several years, his last words when he died were: Thank you for that tree!
Look! How profound nature is, although silent, it can give people extraordinary power.
Yes, there are many similar stories. Mature ears of wheat droop their heads, which is teaching us humility. A group of ants can carry big bones, which is teaching us unity. Gentle water drops can pass through rocks, which teaches us tenacity. Bees are busy shuttling among flowers, which teaches us to work hard. The poor grass silently closed the leaves, which told us not to overstretch the fields.
Yes, nature is the best teacher. As long as we are willing to study, we will gain something every day.
/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.
