Science and technology literally refer to both the actual processes and the materials used in the manufacture of different services and products, and the theories and principles that guide them. It also includes the physical resources that make up the earth and the living organisms on it. Science and technology have become a major part of our lives and have significantly affected all aspects of human activity, be it transportation systems, information exchange, communication, or manufacturing. A lot of technological innovations have been introduced in the past century to address these issues, and newer fields and technologies continue to emerge.
One of the most significant effects of science and technology is the impact it has had on our society. Science and technology have opened the doors of opportunity for people around the world, giving them the opportunity to participate in scientific and technological research and development, and reap the benefits eventually. Not only does this help the economy by creating jobs, but it also helps to maintain international cooperation and diplomacy. Science and technology play a large role in the public welfare of society, because it has helped eliminate some of the most devastating diseases and environmental issues in the past century. Without the scientific knowledge to detect and treat these problems, many people would have perished.
Another important effect of science and technology is its impact on the economy. Science and technology have enabled the industry to develop, providing jobs for a large number of people and industries, as well as facilitating the economic growth of countries with such advances in their economy. Science and technology have also contributed significantly to the betterment of society by developing the society and infrastructure that are required for the betterment of human health and society as a whole. Given all the contributions that science and technology have made to our lives, it can clearly be said that without the scientific advances of the past century, many things today would not be possible.
