The book "Equalities of the state of solids at high pressures and temperatures", written by B. N. Zharkov and V. A. Kalinin, is a unique study that immerses the reader in the complex and fascinating world of solid-state physics. This publication will be a real find for students, graduate students and specialists in the field of physics, materials science and engineering, as well as for anyone interested in modern scientific research in the field of high pressures and temperatures. The book discusses the basic principles underlying solid state equations, which play a key role in understanding the behavior of materials in extreme conditions. The authors analyze in detail how high pressures and temperatures affect the physical properties of various substances, which in turn opens up new horizons for application in areas such as geophysics, astrophysics and materials science. The reader will be able to learn how state equations help predict the behavior of materials in conditions that may arise, for example, in the bowels of planets or in the process of creating new materials for high technology. The book will be especially interesting for those who are fond of physics and chemistry, as well as for those who work in scientific and research institutes. Students and graduate students studying the physics of solids will find in it a lot of useful information that will help them deepen their knowledge and prepare for scientific activities. It will also be useful for engineers and specialists working with new materials, since understanding state equations is an important aspect in the development and testing of new technologies. The topics raised in the book cover a wide range of issues, ranging from theoretical foundations to practical applications. The authors emphasize the importance of experimental data and their interpretation, which makes the book not only a textbook, but also a guide for practitioners. It considers both classical approaches and modern methods, which allows the reader to get a complete picture of the current state of science in this field. The style of the authors is distinguished by clarity and accessibility, which makes complex concepts understandable even for readers who do not have deep knowledge in the field of physics. In. N. Zharkov and V. A. Kalinin — experienced scientists whose work has already proven itself in the scientific community Their previous publications also deal with issues of physics and materials science, which confirms their expertise and deep understanding of the subject. The book "Equalities of the state of solids at high pressures and temperatures" is not just a collection of theoretical knowledge, but also a practical guide that will help readers better understand how the physics of solids affects our lives and technologies. It will be a useful resource for those who seek to expand their horizons and deepen their understanding of the physical processes taking place in our world. If you are looking for books on physics, materials science or just want to learn more about how high pressures and temperatures affect materials, this edition will be a real find for you. Do not miss the opportunity to immerse yourself in the fascinating world of science together with the “Equations of the state of solids at high pressures and temperatures”!
