Book excerpt: The work (which has had seven editions in Russian, the latest in 1970-1) is widely used in Soviet secondary schools and technical colleges, and is equally popular with pupils and teachers. The material is presented in clear, simple language with a wealth of illustrations, which makes it useful as a means of independent home study. Its merit is that it gives a basic explanation of the physical aspects of various processes in nature and technology, taking into account the latest advances in each field. This book covers the problems pertaining to the study of oscillations and waves. Mechanical oscillations and elastic waves are followed by a discussion of acoustic. The chapters on electromagnetic oscillations and waves naturally lead to the study of the most important practical applications of these problems --- to the discussion of the fundamentals of radio physics and radio engineering beginning with the invention of radio by A. Popov, of the electromagnetic nature of light, and of the principles of wave (physical) and ray (geometrical) optics. The volume ends in a description of the phenomena related to the modern theory of the atom.Great effort was made in these volumes for the student to understand the physical essence of the phenomena being considered. Mathematical deductions again occupy little space. The number of questions not contained in secondary school curricula is very limited, but with the aim of making the material quite clear, the authors considered many questions in greater detail than is usual practice in secondary school textbooks.It should also be noted that the exposition of the phenomena of atomic and nuclear physics deals with a greater circle of questions than is the rule in school instruction. The authors followed the purpose of considering these questions with sufficient detail, with a view to students most interested in these topics. On the other hand, in these chapters it is difficult to explain all the problems dealt with quite consecutively, so that this part of the book has the nature of a textbook to a smaller extent than the remaining ones.
