We have tried to write this book in a light and simple style, not denying ourselves the pleasure of an occasional joke with the reader. But this does not in any way mean that our Physics for Everyone is an easy book. Many of its pages must be read attentively for a long time; in order to understand physics, one must very often think hard and tensely. The book's main concern is the fundamental laws and concepts of physics. However, we have tried not to forget about illustrations from life and technology, true, not having the aim of dealing in any way with the inexhaustible field of applied physics.
