in how and why something happens or has happened. A theory is considered to become a part of scientific knowledge if it has been tested experimentally and proved to be true.
Scientific study can be divided into three major groups: the natural, social, and technical sciences. As scientific knowledge has grown and become more complicated, many new fields of science have appeared. At the same time, the boundaries between scientific fields have become less and less clear. Numerous areas of science overlap each other and it is often hard to tell where one science ends and another begins. All sciences are closely interconnected.
Science has great influence on our lives. It provides the basis of modern technology - the tools and machines that make our life and work easier. The discoveries and inventions of scientists also help shape our view about ourselves and our place in the universe.
Science and technology.
Technology means the use of peoples inventions and discoveries to satisfy their needs. Since people have appeared on the earth, they have had to get food, clothes, and shelter. Through the ages, people have invented tools, machines, and materials to make work easier.
Nowadays, when people speak of technology, they generally mean industrial technology. Industrial technology began about 200 years ago with the development of the steam engine, the growth of factories, and the mass production of goods. It influenced different aspects of peoples lives. The development of the car influenced where people lived and worked. Radio and television changed their leisure time. The telephone revolutionized communication.
Science has contributed much to modern technology. Science attempts to explain how and why things happen. Technology makes things happen.
