Modern electronics
Many scientists believe at present that mankind has entered the era of a new technological revolution which was brought about by the advent of cybernetics, whose ideas and methods found their way into virtually all branches of science and engineering, all the way from biology and medicine to economy and industrial management.
Electronics is one of the main sciences, which forms the technological basis for using these new methods. Electronics studies the problems connected with the application of instruments and devices, the action that is based on the utilization of various phenomena that result from the movement of electrons through vacuum, gases and solid bodies.
Electronics surrounds us everywhere. Television, tape- recording, radio-receiving-electronics is at the heart of them all. That is only a small part of electronics and not the most important at that. Extremely complicated electronic systems control the work of huge plants, enterprises and power stations. Electronic appliances are indispensable for planning and controlling our national economy. Electronic computers are widely used in scientific research and industrial designing. Huge radio telescopes, equipped with sensitive instruments and powerful amplifiers enable man to gain an insight into the remotest corners of space, discover new and puzzling phenomena of nature.
Now humanity is in the second decade of the cosmic era. It was in 1957 that the first man – made satellite was launched in our country, and now man has already set his foot on the Moon, sends probes distant planets and orbits to the earth in space vehicles. All this could not have been done but for electronics.
