Book 1580 Crystallography and Crystal Chemistry: Razd. Indication of planes and directions in crystals: study. Rosin K . M. and Petrakova V. C. is an indispensable resource for students, graduate students and anyone interested in crystallography and crystal chemistry This tutorial not only illuminates the theoretical aspects of indicating planes and directions in crystals, but also offers practical tasks, making it ideal for a deep understanding of the subject. Crystallography is a science that studies the structure of crystals, their symmetry and properties, and crystal chemistry investigates the relationship between the crystal structure and the chemical properties of substances. The book by Rosin and Petrakov focuses on the indication of planes and directions, which is a key aspect in understanding the crystal structure. The authors offer the reader not only theoretical foundations, but also practical examples, which allows to better assimilate the material. This book will be of interest to students of natural and technical specialties, as well as teachers and researchers working in the field of materials science, chemistry and physics. It is suitable for both beginners and more experienced readers who want to deepen their knowledge in this area. If you are interested in topics such as crystal lattices, crystal symmetry or methods for determining structure, then this manual will be a real find for you. Key topics that are raised in the book include methods for indicating planes and directions, the use of different coordinate systems, and their influence on the interpretation of data. The authors pay attention to practical aspects, such as the use of software for analyzing crystalline structures, which makes the material especially relevant in the light of modern technologies. The book also addresses issues related to the application of crystallography in various industries, including pharmaceuticals, materials science and geology. The style of the authors is clear and accessible, which allows the reader to easily assimilate even the most complex concepts. Rozin and Petrakov are known for their scientific works and teaching aids, which are popular among students and teachers. Their previous work also covers a wide range of topics related to crystallography and crystal chemistry, which confirms their authority in this field. The book “No. 1580 Crystallography and Crystal Chemistry” will become a reliable assistant for those who want not only to study the theory, but also to put their knowledge into practice. It will help develop analytical thinking and teach a critical approach to solving problems, which is an important skill for future scientists and specialists. If you are looking for a tutorial that combines theoretical foundations and practical tasks, then this edition is your ideal choice. Do not miss the opportunity to immerse yourself in the fascinating world of crystals and their properties with the help of the book by Rosin and Petrakov.
