Science and technology are the primary productive forces and play an important role in the development of human history. In human life, science and technology are widely used in various fields.
In agriculture, due to the application of science and technology, human beings have cultivated hybrid rice and genetically modified fruits ..... to continuously increase grain output and optimize grain quality. Humans have also invented all kinds of seeders, fertilizers and harvesters ..... which makes the labor force put into agriculture less and less.
In medical treatment, due to the application of science and technology, people have invented various high-tech medical instruments and drugs, which can treat patients painlessly and prolong people's life.
In national defense, due to the application of science and technology, scientists from various countries have invented various scientific and technological weapons ―― aircraft carriers, missiles, fighter planes, radars, etc. They play an important role in safeguarding the territorial integrity of the country.
In life, due to the application of science and technology, we invented telephones, televisions, computers, cars and airplanes ..... so that we can go to heaven and get in touch with people thousands of miles away.
Technology is amazing! Scientists are so great!
I love science, because if there is no science, Armstrong, who is well-known to women and children all over the world, will be submerged in the vast sea of people like an ordinary youth and stagnate; Without science, people can't create one invention after another; Without science, Galileo in the17th century might never get ahead in his life.
Science is everywhere, which facilitates the communication between China and foreign countries. For example, if you chat with a foreign compatriot, but you can't speak a foreign language and the other person can't understand Chinese, then at this time, science can come in handy! You can buy a translator, so that you can talk with friends all over the world. Science can make human life better.
Because of TV, people can learn about big things, small things and things happening in the world faster; Because of the telephone, people can tell the truth with distant relatives and friends more quickly; Because of the plane, we can drink and chat with friends from all over the world as quickly as possible. What do these depend on? It is science! Most importantly, science is a magic weapon for human beings to fight against natural disasters in difficulties. Take the earthquake of magnitude 8 that occurred in Wenchuan, Sichuan on May 12 as an example. Many people survived the earthquake because they knew that human urine contained salt, so they drank urine instead of water to maintain their lives and waited for help. After the earthquake, the rescue team rescued many people. Why? Because they have a treasure life detector that can save people from fire and water, it can detect the position of the living according to the heat energy emitted by the human body. This is science!
Science is everywhere, let's swim freely in the ocean of science!
Some people say that science is terrible, while others say that science is interesting. In my opinion, science is interesting because it is terrible, and science is terrible because it is interesting. Today, I came to Zhejiang Library to have a close contact with a great British scientist and a great cartoonist. Are they Nick? Arnold and Tony? Dessauce.
The two of them jointly published a series of interesting children's science books, telling terrible science. At about 8: 50 this morning, our reporter from Hangzhou Net came to the conference room of the library early, waiting for Nick? Arnold and Tony? The existence of decubitus ulcer. About 10 minutes later, I saw two approachable people? Foreigners? As soon as they came in, they said, Nick? Arnold and Tony? Dessauce.
They brought us many performances, among which Nick's scientific experiment was my favorite. The name of this experiment is: eggs that can't be broken by shaking. First take a cup and fill it with water, then put an egg in the water and shake the cup desperately. Guess what? The egg is not broken! Under our questioning eyes, Nick solved the mystery for us. Because the eggs were boycotted!
Science is very interesting and terrible. Many scientists have been killed to stick to the truth. I should cherish the scientific achievements now, because they may have been bought with the lives of one or two or even more scientists!
