At first, the computer needed a room to hold it, and several people had to work together to operate it. At that time, the computer was running very slowly, and it took a long time to calculate a mathematical formula.
But because of the progress of science and technology, the computer has become a pure screen computer, which runs faster, but its size has become smaller, so one person can operate and move! The most important thing is that computers have more and more functions.
With the continuous efforts of scientists, pure screen computers have become liquid crystal computers. The computer screen is very thin, with little radiation and much clearer screen.
Under the research of scientists, LCD computers have become portable computers with more functions, which can be carried around and communicated with people all over the world on the train.
This is the process of computer development! This is the change brought by the development of science and technology!
Chapter 2: Founder of scientific and technological development.
How amazing the development of science and technology is now, and the living standard of human beings is also improving step by step. However, when New China was just founded, China's heavy industry was very backward, and its science and technology were not very developed, so it was in urgent need of a large number of economic, scientific, cultural and educational talents.
But at that time, China was an oil-poor country. In addition, American scientists have concluded that China has no oil reserves underground. Just when everyone was desperate, one person said: Science has proved that China is rich in oil and natural gas resources. He is Li Siguang, an outstanding geologist in China. It is said that after the birth of People's Republic of China (PRC), Li Siguang returned to the embrace of the motherland in the spring of 1950, and joined the China * * * Production Party in 1958. Subsequently, Daqing Oilfield with large scale and high output was proved, and China got rid of the label of "oil-poor country", which made the world sit up and take notice.
Geologist Li Siguang got rid of the label of "oil-poor country" for China, and Yuan Longping contributed to the complete set of hybrid rice seed production technology in China.
From 65438 to 0973, Grandpa Yuan Longping cultivated and developed a set of hybrid rice seed production techniques. After Grandpa Yuan Longping developed hybrid rice, many international organizations hired him to work abroad with high salaries, but he declined politely: "My roots are in China, and my goal is not only to feed the whole country, but also to eat well." Grandpa Yuan Longping often said, "You can't be a scientist if you don't love your country."
There are many talents in our country. It is precisely because of these talents that our country can be rich and strong. However, these talents can only stand up after layers of tests and hard training; In the field of science and technology in China, these people, as pioneers, wrote their own glorious side and became the founders of science and technology in China. 1964, China's first atomic bomb exploded successfully. 1970, the "Dongfang-1" artificial earth satellite was successfully launched. These examples are enough to prove that science and technology in China are developing rapidly. I think as a student in the 2 1 century, we should study hard and strive to make greater contributions to our motherland.
Chapter III: Changes brought by the development of science and technology.
Today, the teacher assigned a composition. The requirement is: read the text taught today to mom or dad, ask them to talk about the changes brought about by the development of science and technology, and then write down their words. In the evening, my father came back, and I couldn't wait to ask, "Dad, please tell me what changes technology has brought us?" Dad said: "Modern technology can develop, and water heaters and electric lights have been invented, which has added convenience to our lives." I was puzzled and asked, "Dad, how did you live at that time?" Dad replied: "At that time, we could only boil water with coal and light with matches, which was not as comfortable as it is now, such as water heaters and electric lights." I broke the sand pot and asked, "Dad, how do you harvest food?" Dad said, "In the past, the harvesting tool was a sickle, but now there is a harvester tooting, and farmers are sitting on the harvester, laughing like a blooming flower." These high technologies have brought farmers the joy of harvest and infinite hope, and the development of these technologies has brought one surprise after another to our lives. "
Ah! Today, with the development of science and technology, our life is getting better and better. I believe that through our continuous efforts, our life will be icing on the cake!
Chapter IV: Harmonious development, and * * * creation and development.
We humans are on the same earth. Why can't we work together for the development of science and social progress? Why do some people like to steal, steal and fight? But some shameless people rob in broad daylight, which shows the lack of unity in modern times. If a person robs in front of you, people will have two choices. One is to help the robbed person, and you will become a hero in that person's heart. If everyone lends a helping hand when others are robbed, there will be no more robbers in the world. Second, when you don't see it, in the long run, robbers will rob your house sooner or later. Why are human nations in different countries? Why can't we merge into one family and develop together? People always think that the technology of aliens is more advanced than that of earthlings, but I believe that countries on other planets must not exceed 10. We are all a small particle in the universe. Why do some people have no dignity and some people like to bully the weak? In today's society, some women actually sell their bodies for some immediate interests, insulting and humiliating the only and noblest and most sacred emotion of mankind. Beethoven once said a famous saying; Physical union without love is like animals. Why can't they make a career by their own efforts? Now many women have become successful! Mr. Lu Xun once said a famous saying: "If a person dies and is not remembered, then he is really dead." Therefore, we human beings cannot be blinded by immediate interests. We should look to the future. If a person doesn't live for decades, he will live his whole life in vain. Why is our human science and technology developing so slowly? This is because the earth is actually divided into hundreds of countries, and each country is only for its own interests and scientific and technological development. If countries discuss and integrate their own scientific and technological achievements and jointly develop world science and technology, then human beings are not only the masters of the earth, but also the masters of the universe.
Article 5: Technology is with me.
Everyone is familiar with the word technology. Computers and televisions are gifts of technology. Since Watt invented the steam engine, the whole world has entered the era of science and technology. Since Edison invented the electric light, we have left the darkness and worshipped technology more; Newton discovered the law of gravity because an apple fell from the tree, which made science and technology take a big step forward.
Technology is fun, which contains at least several meanings. First, science and technology itself and the natural laws governing the universe are full of charm; Secondly, the process of exploring science and technology and revealing the laws of nature is also very interesting. Third, once science collides with life, there is a relationship between science and technology and human society-both positive, negative and interesting.
Technology is everywhere, and technology makes human beings extremely proud!
How important technology is to us, if one day, without electricity, people will continue to live in darkness; Without gas and oil, wouldn't people want to eat raw things or drill wood to make a fire and continue to pull carts with raw animals? Without mobile phones and computers, do people still use flying pigeons to pass books?
From this perspective, we can't live without the contribution of science and technology all the time. I believe everyone around us is exploring and contributing to the development of science and technology in their own way ... Although I am naughty, I really experienced the taste of technology: I put some baking soda powder in the quilt and then added white vinegar, and then the volcano erupted! Suddenly, white vinegar emerged.
With the rapid development of science and technology, science not only serves the cutting-edge technology, but also penetrates into our daily life more and more, which requires us to love and learn science in our youth. I participated in the provincial science and technology innovation and invention competition and won the second prize. He also participated in the municipal science and technology innovation and invention competition and won the third prize. These achievements are inseparable from the hard work of teachers. Participating in science and technology competitions and reading science and technology books have made me understand a lot. Precise robots, cars without fuel, virtual football matches, high-tech information transmission, and so on, vivid and interesting phenomena have aroused my desire to explore science more and more. Each of us should study science, spread civilization and create a new life while enjoying life. Nowadays, the technology products are updated faster and faster, and video TV, computer surfing and pacemakers are not new. From the vacuum cleaner invented by 190 1 to artificial earth satellites and manned spacecraft, science and technology have shown great power in different fields. With the popularization of electronic industry and communication technology, and the wide application of nanotechnology and superconducting materials, bioengineered foods such as space green peppers and artificial steaks will appear on your table in the near future. Studying science and technology is not only to become a scientist and adapt to life, but more importantly, to become the master of the new century, to undertake the new century and to make contributions to national construction and human civilization.
Since the founding of New China, China has made rapid progress in science and technology, such as synthesizing insulin, replanting severed hands, hybrid rice, exploding atomic bombs and hydrogen bombs, and launching satellites and spaceships. These remarkable scientific and technological achievements have greatly shortened the gap between China and advanced countries and injected vitality into China's modernization drive. Grandpa Deng Xiaoping said that "science and technology are the primary productive forces". Indeed, science has given wings to the take-off of our motherland. President Mao Zedong once told young people that the world is your and ours, but in the final analysis, the world is your. This sentence is full of the ardent expectations of our elders. If the elders of the 20th century built the motherland with hard work, then we should shoulder the burden of the new century with knowledge and science.
Chapter VI: Sustainable Development and Sustainable Progress
China is a developing country, and it's really not easy to develop from the backwardness in the past to the present. After 60 years of ups and downs, China, the Oriental Dragon, finally stands in the world and deserves our pride.
On June 5th, 2007, the17th National Congress of China * * * Production Party was held in Beijing. President Hu Jintao pointed out in his report: "Scientific Outlook on Development is the inheritance and development of the important thoughts on development of the party's three generations of central leading collective ..."
Yes, China needs to develop and is developing. The development of China is an important part of world development. The development of the world cannot be separated from China, and the development of China cannot be separated from the world. If a country and a famous nation don't develop, it means that they are backward and will always stay on the good road of progress. Countries that don't develop will soon be eliminated by the world. People compete with each other and countries compete with each other. People compete for money, power and power, while countries compete for development.
It is better to talk about development than progress.
Development seems to be the development of national economy, science and technology and other major events; But progress shows that a country's progress, development and people's progress are not people's progress. The common people in the world are the foundation of development. Isn't this small and insignificant progress a success of development? The people have made small progress in quality, morality and culture before they have created great development.
Progress seems to be the progress of national civilization, morality and other small things: but development is only carried out on progress, and the two complement each other. Is it not good to talk about development in terms of progress and progress in terms of development?
Development is for progress and for the benefit of ordinary people; Progress is for better development and the future of the country. In the final analysis, it is not for the happy life of the public, but for a better tomorrow of the motherland.
