The book is dedicated to the history of outstanding discoveries and inventions in the field of electrical engineering, power engineering and radio electronics. The history of electrical engineering is described in most detail - from the first observations of electrical and magnetic phenomena even before our era to the creation of modern devices, machines and instruments. The origins of radio electronics are examined more briefly - from the discovery of thermionic emission to the creation of the first radio receivers, radio tubes and the emergence of microwave technology.

The book may be useful to young people embarking on the path of creativity - high school students, students, graduate students, young engineers and scientists, as well as aspiring teachers of physics and electrical engineering.
