For example, the invention and improvement of the steam engine in the first industrial revolution pushed mankind to age of steam, and the social productive forces developed greatly.
The application of electricity in the second industrial revolution brought mankind into the electrical age.
For example, the invention and application of telephone and telegraph promoted the development of human telecommunications, made people's communication more convenient and promoted economic development and social progress.
The invention and application of electronic computers and the application of information technology in the third scientific and technological revolution have brought mankind into the information age.
Nowadays, the Internet enables people to know the state affairs and current affairs news for the first time, and they can enjoy the book without leaving home, that is, "a scholar doesn't go out, and the world knows it." .
There is also the development of transportation, so that distant relatives can visit relatives in different places. Medical development has cured many serious diseases, and people who have lost their organs can be cloned.
Second, promote people's mode of production, lifestyle and way of thinking.
It promotes the development of productive forces, improves people's material and spiritual living conditions and improves people's quality of life. Accelerate the pace of social life and change people's ways of work and rest, communication, study, consumption and entertainment.
Bring us into the information age. It provides us with the means to process, store and transmit information, and brings convenience to study and work. Modern transportation, communication and other means make the earth smaller, and people communicate conveniently and quickly. At the same time, it will promote the development of the tertiary industry and the socialization of family functions, and part of the early education and housework originally undertaken by the family will be separated and undertaken by the society. The application of electronic computers enables human beings to engage in spiritual production and creative activities in science, art, culture and education instead of the production of material materials needed by human beings. With the improvement of labor productivity, people can develop in an all-round way and move towards the highest ideal!
With the development of society, science and technology are more and more developed. It is precisely because of the development of science and technology that our life is getting better and better and more convenient.
For example, our population is increasing now. Due to the development of science and technology, buildings can be built higher and higher, thus reducing the pressure on the ground. Moreover, most of us now use the elevator to go upstairs and downstairs, which is much more convenient. Look at our present kitchen, which uses high-tech development products such as natural gas, microwave oven and refrigerator, which greatly reduces our cooking time. And the computers and telephones we use every day. Computers enable us to achieve many things that the human brain can't achieve for the time being. Through the internet, we can solve many doubts in our hearts. What about the phone? It is convenient for our communication, especially the mobile phone, so that we can communicate anytime and anywhere.
So the great Deng Man Xiaoping once told us that "technology is the primary productive force"!
With the development of science and technology, human beings have also paid a high price.
First, it consumes a lot of resources, intensifies the pressure of resource shortage, destroys ecology and environment, and brings air pollution to mankind. These are the most direct and obvious disadvantages.
Second, the extinction of species is accelerating. This is caused by environmental pollution and human hunting, and it also belongs to the disadvantages of scientific and technological development.
Third, personal safety is increasingly insecure. Now there are tens of thousands of crimes every day on average, and their criminal methods are related to the new technology in Otawa, especially gun crimes, which make ordinary people hard to prevent. From the Second World War, we can already see that with the development of science and technology, the damage and losses caused by the current war are far from being comparable, and may even lead to the fate of human extinction.
Fourth, people's physical fitness is not as good as before. With the development of science and technology, the emergence of vehicles such as air cars, trains and planes has greatly changed human daily life. Humans no longer always rely on their own legs, so the physical quality of human beings can't be compared with before. In today's society, Xiang Yu can't "pull out mountains and rivers" as in the past, but if this situation continues to develop, it may shrink people's limbs and bring about new forms of human beings.
Fifth, all kinds of emerging germs are constantly emerging. The lethality of many germs has far exceeded the destructive power of previous germs. This is because the rapid development of medical science and technology has accelerated the mutation of virus, so that the development speed of science and technology can't keep up with the mutation speed of virus, and maybe one day mankind will perish from a great plague.
