The Book of Physics . Sections "Mechanics. Molecular Physics . Thermodynamics" by O. A. Denisova is a fascinating and deep dive into the world of physics, which will be an indispensable tool for both students and anyone interested in the basics of this science. In his work, the author masterfully combines theory and practice, offering the reader not just a set of formulas and laws, but a whole system of knowledge that will help to understand how the world around us works. The book details three key areas of physics: mechanics, molecular physics, and thermodynamics. Each of these sections is revealed through the prism of modern scientific achievements and classical theories. Mechanics, as the basis of physics, explains the laws of motion and interaction of bodies, which is important for understanding not only physical processes, but also many phenomena in everyday life. Molecular physics, in turn, immerses the reader in the world of particles, their interactions and properties, which opens new horizons for understanding chemical and biological processes. Thermodynamics, with its laws and principles, helps us understand how energy is transformed and transmitted, which is key to many of the technologies and processes we face on a daily basis. The book will be of interest not only to students and schoolchildren studying physics, but also to teachers who are looking for accessible and understandable explanations of complex topics. It will also be useful for science lovers who want to expand their knowledge and look at physics from a new perspective. About. A. Denisov uses an accessible language, which makes the material easy to understand, and rich illustrative material helps to better absorb information. The topics raised in the book are relevant and important for modern society. Understanding physical processes helps not only in learning, but also in everyday life - from simple everyday phenomena to complex technologies. The book inspires further study of physics and related sciences, emphasizing their importance in our world. Style O. A. Denisov is distinguished by the clarity and logic of the presentation .
