What is Radio Electronics?

HOW DID SUCH A SCIENCE AS ELECTRONICS APPEAR? The purpose of this lesson is to give an idea of electronics as a science — a branch that, both in the past and today, fills its niche in almost all areas of the national economy, education, and technology. In this lesson, you will also get an idea of the structure of matter and electrically charged particles. We will also touch upon the structure of the atom, the concept of electricity, and the electrification of bodies. At the end of the lesson, there will be a small practical assignment. As the large encyclopedic dictionary tells us, ELECTRONICS is the science of the interaction of charged particles (electrons, ions) with electromagnetic fields and the methods of creating electronic devices and equipment (vacuum, gas-discharge, semiconductor), used mainly for the transmission, processing, and storage of information. Electronics as a science emerged in the early 20th century; initially, it was mainly vacuum electronics that...
