The book "No273 Crystallophysics: Mineralogy of Natural Processes: a Course of Lectures" written by the author's team as part of T. I. Small, N. R. Mansurova and O. In. Blue is a fascinating and deep dive into the world of crystals and minerals, exploring their physical properties and the natural processes that shape our planet. This publication will be a real find for students, graduate students, teachers and anyone interested in geology, mineralogy and physics. Crystallophysics is a science that studies the structure and properties of crystalline bodies, and in this book, the authors offer readers not just theoretical knowledge, but also practical aspects that will help them better understand how minerals form in nature. The book covers a wide range of topics, ranging from the basics of the crystal lattice to complex crystallization processes, making it a valuable resource for those who want to deepen their knowledge in this area. One of the key features of the book is its accessible and understandable style of presentation. The authors aim to make complex scientific concepts accessible to a wide audience, which is especially important for students and beginning researchers. The book is filled with vivid illustrations and diagrams that help to visualize the processes studied and make the material more visual. This is not just a collection of lectures, but a real learning platform that inspires further study of crystal physics. The topics raised in the book cover not only the physical and chemical properties of minerals, but also their role in ecosystems, as well as the influence of various natural factors on their formation. Readers will be able to learn about how crystals affect the environment, as well as their practical application in various industries, from jewelry to high technology. This book will be of interest not only to students of geological specialties, but also to everyone who is fond of nature, its processes and beauty. The book 273 Crystallophysics can also attract the attention of those interested in ecology and sustainable development. Understanding the processes of mineral formation and their interaction with the environment can help in the development of more effective methods for the use of natural resources and the protection of ecosystems. The authors are experienced specialists in the field of mineralogy and crystallphysics. T. I. Small, N. R. Mansurova and O. In. Golubev - well-known scientists who have made a significant contribution to the development of this field of knowledge Their previous work has also gained recognition in the scientific community, and this book continues the tradition of a qualitative and in-depth approach to the study of minerals. Readers familiar with their other publications will find familiar ideas in this publication, but in a new light, which makes it particularly valuable. Thus, “273 Crystallophysics: Mineralogy of Natural Processes: A Course of Lectures” is not just a textbook, but a real encyclopedia of knowledge that will help readers understand complex natural processes and their impact on our lives. This book will be an excellent addition to the library of anyone who seeks to expand their horizons in the field of mineral and crystal science. Do not miss the opportunity to immerse yourself in the exciting world of crystal physics and discover new facets of natural processes!
