Technological revolutions are qualitative changes in technological methods of production, the essence of which is the radical redistribution of basic technological forms between the human and technical components of the productive forces of society. All the technological changes occur sequentially and continuously. But it is possible to allocate periods of technological change, which lead to the production of a new qualitative level. The impetus for the technological revolution usually becomes the accumulation of a certain critical amount of knowledge about the world, which together with the growing needs of people contributes to the search for new and more efficient production methods. A characteristic feature of the technological revolutions in the history of mankind is the exponential growth rate of technology development. The cycle between each technological revolution becomes shorter each time.
During the first technological revolution manufactories were replaced by factories, where most of the work was carried out not by people, but by machines. Such a transition was made possible after the invention of steam engine by James Watt. The first technological revolution was of great importance in the history of mankind. Significant growth of industrial production made it possible to introduce machines in production, which led to an influx of the labor force in cities. Most of the achievements of that time were successful solutions of inventors and engineers, received as a result of trials and errors rather than theoretical substantiation of efficiency of application of various technologies in the workplace.
The second technological revolution is associated with the introduction of new energy sources, development of the chemical industry, and metallurgy. With the invention of an inexpensive industrial production of stainless steel heavy industry was developed. Gas and oil came in place of the coal. There were efficient internal combustion engines, which eventually began to replace steam engines. This was the time of studies of the phenomenon of electricity and its transmission over long distances. At this time, the telegraph, telephone, radio, and television were invented.
Unfortunately, along with the improvement of the quality of human life, technological revolutions bring negative consequences. If in the era of agrarian society people only oppressed nature, cutting down forests for fields and pastures, with the development of technologies that influence began to acquire a depressing character.
