Practical examples of applying reduction to absurdity in daily life prove that the food in this restaurant is terrible.

Suppose it's delicious, then business is good on a weekend night, but there are no customers, so it's contradictory, so the assumption is not true, so it's delicious.

The science in our daily life is about 200 words in the fifth grade of primary school. Science and technology is the representative of 2 1 century. In our life, there are traces of technology everywhere. 2 1 century is a technological era. We can't live without life, and life can't live without technology. Therefore, science and technology are indispensable in our life.

bionics

Man is a very clever animal with Qian Qian's ideas. We want to become fish and swim in the sea. We want to become birds and soar in the sky; We want to become a cheetah and run freely on the boundless grassland ... In order to realize our wish, people imitate the habits, structures and life characteristics of animals and apply this knowledge flexibly to housing construction, military affairs and so on. This is the famous bionics.

thin shell structure

In the familiar Great Hall of the People, it is built according to the principle of bionics. The designers who designed the Great Hall of the People used the thin shell structure of eggs. As we all know, when we peel eggs, we won't crush them easily. If we just let them die, it can only be very tired. Therefore, we pick up a corner of the egg and knock it in a sharp place before we can crack it. This is the dispersed stress structure of eggs, and the Great Hall of the People was built with this structure.

Lingyuan Zhonghua Shuilong

On the earth where we live, there are hundreds of animals. Some of them fly in the sky, some swim in the ocean, and some run on the grassland. Every animal has its own lifestyle and behavior habits. Every animal is an individual, and they all look different. In modern times, scientists put two kinds of animals together to mate, which will produce new species. For example, the common hybrid species now is the tiger lion or the tiger lion beast. The tiger lion refers to the cubs born when the lion is the male and the tiger is the female, which is called the tiger lion; Tiger lion beast means that the tiger is male and the lion is female, and the cubs born by mating are called tiger lion beast. Now in yunnan wild animal park, near the Golden Temple in Kunming, Yunnan, a male sheep and a female sika deer fall in love. So, will there be one more creature in the world? Let's wait and see.

cloning technology

In the fairy tale of The Journey to the West, the Monkey King, a man with miraculous powers, changed himself several times by blowing a hair on his head. Fairy tales are fairy tales after all, and can't be taken seriously. However, this phenomenon can occur in this 2 1 century of scientific and technological development. Dolly, the first cloned sheep in the world, do you know how he was born? It was born in England on 1996. The difference is that the ewe that gave birth to it is not its biological mother. It turns out that he didn't develop from a fertilized egg. There are not one ewe related to her identity, but three ewes. The process is as follows: scientists first extract the nucleus from the egg cells of sheep A, then extract the nucleus from the mammary cells of sheep B and inject it into the seedless egg cells from sheep A, thus obtaining the egg cells with the nucleus of sheep B. This egg cell divides to form a small embryo. Then transfer this embryo into the uterus of sheep C and let it continue to develop. After a while, a lively and lovely lamb was born. This is Dolly. Although little Dolly was born from sheep C, she looks nothing like sheep C, but almost exactly like sheep B. ..

Our life is inseparable from science and technology, which is closely related to our life. Science and technology are the greatest wealth in our world. Science and technology make us progress and make us live better in this world. Science and technology are widely used in housing construction and aerospace. 2 1 century is an era of science and technology, which is everywhere.

Examples of evaporation in daily life are usually evaporation: drying clothes, drying rivers and drying hair.

The white gas that can be seen after water is boiled is liquefied.

Examples of noise in daily life The source of noise

There are three main sources of noise, namely traffic noise, industrial noise and living noise.

traffic noise

Traffic noise is mainly produced during the execution of vehicles. Such as cars, planes and trains, are all sources of traffic noise. Investigation shows that motor vehicle noise accounts for 85% of urban traffic noise. The spread of vehicle noise is closely related to the number of roads and the size of traffic measurement. In a city with narrow passages and rows of tall buildings on both sides, the noise is reflected back and forth, which is more noisy. The same noise source sounds 5- 10 decibels higher in the street than in the open space. In motor vehicles, the noise of heavy vehicles such as trucks and buses is 89-92 decibels, and the noise of light vehicles such as cars and jeeps is about 82-85 decibels. The above sound level was measured at a distance of 7.5 meters from the vehicle. The speed of the car is also closely related to the noise level. The faster the speed, the greater the noise, the higher the speed 1 times the noise increases by 6- 10 dB.

Automobile noise mainly comes from automobile exhaust noise. If the muffler is not added, the noise can reach more than 100 decibel. The second is engine noise and tire noise. The engine noise can reach more than 90 decibels when the car is running normally, and the tire noise can reach about 95 decibels when the speed is above 90 km/h. Therefore, installing a muffler in the exhaust system can reduce the exhaust noise of the car by 20-30 decibels. For engines, replacing diesel engines with gasoline engines can reduce engine noise by 6-8 decibels.

In addition, the railway passenger and freight station near the city center has a great influence, especially when the passenger flow is large, because the train has to pass through the urban area. The noise source of subway is similar to that of train. Because the vehicle runs in the tunnel, the noise is not easy to dissipate, which greatly interferes with the people in the carriage. According to the actual measurement in Britain, the noise in the window is as high as 102 decibel.

Although land and water traffic noise has a wide influence, it is still air traffic noise in terms of direct and significant harm. The aircraft is in the period of internal combustion engine, and the noise of air transportation is not prominent. However, after the jet plane appeared, the air transportation noise gradually had a greater impact. On the one hand, the jet noise level is high, on the other hand, it is also the result of the increasingly busy air transport. In fact, the airport will not only produce noise when the plane takes off and lands, but also produce strong noise during airport ground maintenance and aircraft trial operation, which has a great impact on nearby residents. When a large jet plane took off, the language communication on both sides of the runway 1 km was disturbed, and people within 4 km could not rest and sleep.

industrial noise

Industrial noise mainly comes from mechanical vibration, friction, impact and airflow disturbance in production and various working processes. Although the influence of noise and vibration produced by the production and operation of various factories and municipal and building construction in the city is not as wide as that of transportation, the regional pollution is much more serious than transportation. Therefore, the influence of these noise vibrations on the surrounding environment should also be paid attention to.

Life noise

Living noise mainly refers to the sound generated by various living facilities and crowd activities in streets and buildings. For example, in the living room, children cry and play radio, television and audio equipment loudly; Loud voices outdoors or in the street, loudspeakers used for publicity or advertising, etc. These noises can be divided into two categories: indoor noise and public noise. They are generally below 80 decibels, which have no direct physiological harm to people, but will interfere with people's conversation, work, study and rest.

Give two examples to illustrate the scientific knowledge in daily life: 1, suction by straw, atmospheric pressure.

2, light bulb, photoelectric effect.

3, motor rotation, electromagnetic induction.

4. Camera, projector and convex lens imaging.
