The emergence and development of modern science and technology have brought earth-shaking changes to our lives, enabling us to have better contact information, reach our destination faster and shop more conveniently ... These changes have become an indispensable part of our lives. No one can tell what our life would be like without these scientific and technological products in modern society. However, behind the emergence of these scientific and technological products, we have left a lot of enlightenment, which is worth thinking about.

Nowadays, science and technology are developing rapidly, from Galileo's free fall experiment of the leaning tower of Pisa to the advent of ever-changing high-tech products, such as computers and mobile phones (with increasingly advanced functions) and so on.
/kloc-At the beginning of the 7th century, Galileo made a free-falling experiment on the leaning tower of Pisa, which overturned the long-standing misconception that "heavy objects fall faster than light ones". Since then, it has also opened up, and facts are more important than imagination.
Science and technology is the primary productive force and a revolutionary force to promote the progress of human civilization. Entering the 2 1 century, science and technology are changing with each passing day. Scientific and technological progress and innovation are increasingly called the main ways and means to improve the country's comprehensive national strength. Relying on science and technology to realize the sustainable utilization of resources and promote the harmonious development between man and nature has increasingly become a strategic choice faced by all countries. As the core competitiveness, science and technology are increasingly called the focus of competition among countries.
Throughout the ages, every progress of human society is accompanied by the progress of science and technology. In particular, the rapid development of modern science and technology has opened up a broader space for the development of social productive forces and human civilization and effectively promoted economic and social development. The rapid growth of high-tech enterprises such as computers, communications, biomedicine and new materials in the world has greatly improved the industrial technology level of various countries, promoted the labor productivity of industry and agriculture, and effectively promoted the development of the whole world economy. Practice has proved that high-tech and its industries have become the leading industries in contemporary economic development.
Science and technology are the symbols of human civilization. The progress and popularization of science and technology have provided mankind with new means to spread ideas and culture, such as radio, television, movies, videos and the Internet, which has given spiritual civilization a new carrier. At the same time, it is of great significance to enrich people's spiritual life, update people's ideas and get rid of superstitions.
Scientific and technological progress has created enormous material wealth and spiritual wealth for mankind. With the advent of the era of knowledge economy, the endless development of science and technology and its unlimited creativity will continue to make greater contributions to human civilization.
The relationship between science and technology is different in different historical periods, from technology-led to science-led development, from the separation of technology and science to the precise combination of science and technology. The development of modern science and technology shortens the time between the basic research of science and the application and development of technology, especially the birth of system science, which makes automation, computer and communication technology transform rapidly from technology to industrialization. The application of system science in biomedicine leads to the coupling of system biology and synthetic biology, which will quickly lead to the application of system medicine and system bioengineering, thus leading to the biomedical and bio-industrial revolution of individualized medicine, translational medicine and medical engineering system, and making science and technology as the productivity of social and economic development more and more prominent.
In today's world, peace and development are the themes of the times. However, the "cold war" mentality still exists, and hegemonism and power politics are still the main sources that threaten world peace and stability. It is the same choice for a powerful country in science and technology to become a modern country.
The level of modern science and technology has become a bargaining chip in international political struggle and a symbol of great power status. Deng Xiaoping once pointed out: "If China had no atomic bombs, hydrogen bombs and satellites since the 1960s, China would not be a big country with important influence and would not have such an international status."
The productivity of scientific and technological development has created a highly developed material civilization, but improper use of science and technology has caused worldwide environmental problems.
At present, the world labor productivity has been greatly improved. Turning science and technology into productive forces as much as possible will greatly improve production efficiency, thus promoting rapid economic development, and its role greatly exceeds the transformation of the economy by capital and labor.
Modern scientific and technological revolution has greatly improved the role of human subject factors in today's world, which is reflected in the relationship between man and nature. Due to the integration of science and technology, the relationship between man and nature has changed from over-interpretation to control; There is a process from analyzing material structure and natural process to purposefully synthesizing material structure and influencing natural process, and even synthesizing life and influencing life. It shows that people's position in the production system has also undergone important changes. People have changed from people who directly participate in the production process to supervisors and managers who control the whole production process, which has become a key factor to determine the productivity and competitiveness of economic growth.
But in the process of rapid development of science and technology, it left us with profound problems:
Resource problem: there is only one earth for human beings, and the resources on the earth are limited. According to statistics, crude oil on the earth can only be used for 350 years, and coal on the earth can only be used for 3500 years. Although the available substances on the earth can expand continuously, such as hydrogen in water, they will be exhausted one day. In the process of using resources, we must pay attention to saving. For example, at present, China's coal mines and other mineral resources have been dug and mined indiscriminately in many places, which has caused great waste of resources. If positive measures are not taken, this waste will continue and the consequences will be unimaginable. We should think of future generations, save resources and use them effectively.
Environmental problems: the living environment of human beings has been deteriorating. Due to industrialization, there are more and more harmful substances, which will continue to enter the surrounding environment of human life, such as water and air. Now many rivers are polluted, the air in many cities is polluted, and even the food they eat is polluted. Some fish and some creatures are endangered. If this development continues without taking active measures, mankind will eventually destroy itself.
Human activities will inevitably change the natural environment and even destroy the natural ecosystem. At the same time of change and destruction, whether we can establish a new ecological balance through ecological construction from the overall concept of natural environment is undoubtedly the key to determine the favorable or unfavorable feedback of geographical environment. Therefore, we should not only preserve certain natural ecosystems to protect species resources and improve the environment; It is also necessary to establish an artificial ecosystem that is beneficial to human beings and does not lead to environmental deterioration, create higher productivity, and make human society and nature form an organic ecosystem.
