The book "Thermal radiation of cavities" by Sergey Petrovich Rusin and Vladislav Eduardovich Peletsky is a deep and fascinating study in the field of thermodynamics and physics. This work will be a real find for students, graduate students and professionals working in the field of heat exchange, as well as for anyone who is interested in physical processes occurring in different environments. In this book, the authors examine the phenomenon of thermal radiation in detail, focusing on its features in cavities. The reader is immersed in the world of thermodynamic processes, where heat is transmitted not only through conduction and convection, but also through radiation. Rusin and Pelecki explain how various factors, such as the temperature, shape, and composition of the cavity, affect the characteristics of radiation. This makes the book relevant not only for theorists, but also for practitioners working in engineering and design. The topics raised in the book cover a wide range of issues, ranging from the basics of thermal radiation to its application in modern technologies. The authors discuss both classical approaches and the latest achievements in this area, which allows the reader to get a holistic view of the subject. They share their knowledge of thermal radiation measurement techniques as well as process modeling, making the book useful for researchers and engineers. The book will be of interest not only to specialists, but also to those who want to deepen their knowledge in the field of physics. Students of technical and natural sciences will find in it useful materials for preparing for exams and writing term papers . Professionals working in the field of thermal energy can use it as a reference for solving practical problems . And for lovers of science, seeking to understand how the world around us is arranged, the “thermal radiation of cavities” will be a real discovery. The style of the authors is distinguished by clarity and accessibility of the presentation, which makes it easy to assimilate even the most complex concepts. Rusin and Peletsky use many examples and illustrations, which makes the material more clear and understandable. Their approach to explaining scientific concepts helps the reader not only to remember information, but also to realize its practical significance. This book not only expands the horizons of knowledge, but also inspires further research. The authors, with extensive experience in physics and engineering, offer the reader a unique view of familiar things, making you think about how much more to learn about thermal processes. Their previous work is also worthy of attention, and perhaps "Thermal Cavity Radiation" will be a starting point for you to study their other works. If you are looking for literature that combines deep scientific knowledge and an accessible style of presentation, then “thermal radiation cavities” is exactly what you need. This book will be a reliable companion on your scientific journey, opening new horizons and deepening your understanding of thermodynamic processes. Do not miss the opportunity to get acquainted with this fascinating and informative work, which will definitely find a response in the hearts of everyone who is interested in physics and engineering.
