Osnovi radiofonije – zbirka pokusa

Gustav Šindler is the author and editor of the book Basics of Radiophony – a collection of experiments, published in 1951, in the series "Small Library for Mathematics, Physics and Chemistry" School Books.

The work is a practical manual with illustrations, diagrams and tables, which, through a series of simple and feasible experiments, explains the basics of radiophony – from basic electrical phenomena, through radio waves, detectors, amplifiers, to primitive radio receivers. It was written in the spirit of popularizing technical sciences in the post-war period, when there was great interest in amateur radio engineering and electronic construction in Yugoslavia.

Šindler's approach is extremely practical: the emphasis is on the fact that the reader can carry out experiments with simple materials available at the time. The book is intended for high school students, physics teachers and young radio amateurs. The style is clear, concise and pedagogically adapted, typical of the popular-technical literature of the School Book from the 1950s.

In the context of the time, this is one of the early Croatian/Yugoslav publications that popularized radio technology in the period when radio was still the leading mass medium, and amateur construction of receivers and transmitters was a very popular activity. Today the book is considered a rare antiquarian publication and is sought after among collectors of old technical literature and historians of science and technology in Croatia.

The book represents an interesting document on the level of technical education and popularization of science in socialist Yugoslavia in the early 1950s.
