The book provides definitions of basic physical concepts, briefly formulates physical laws and the essence of the phenomena described by them, gives mathematical concepts necessary for using the reference book. This edition has been significantly revised taking into account the new achievements of physical science and the university program of the physics course . The handbook is addressed to engineering and technical workers, students and postgraduates of universities and universities, teachers of higher and secondary schools . Can be useful to anyone interested in physics. From myself: The latest edition from these authors is a truly great reference book (unfortunately, Detlaf passed away in 2003). From the foreword: "This edition in a certain sense sums up the whole era of the brand "Physics Handbook for Engineers and University Students" B. M. Yavorsky and A. A. Detlafa". In fact, all existing physics is described in one thick book. All definitions and formulas are conveniently structured. If you forgot some law - easily find on the alphabetical index. I am not ashamed to say - the quintessence of physics - the book which was used, is used and will be used by schoolchildren and students throughout the country
