The book "Probability Theory and its Application in Engineering and Technical Calculations" by A. Shchukina is a fascinating and in-depth study that opens the world of probabilistic methods and their practical application in engineering to the reader. This work will become an indispensable assistant for students, graduate students and practicing engineers seeking to master the complex concepts of probability theory and learn how to apply them to real-world problems. Author, A. Shchukin is known for his analytical approach and ability to explain complex mathematical ideas in simple and accessible language. In his book, he masterfully combines theory and practice, which makes the material not only understandable, but also interesting. Readers who are already familiar with such works as “Statistics for Engineers” or “Mathematical Methods in Engineering” will find much useful and new in this book. The book begins with the basics of probability theory, where the author consistently introduces the reader to key concepts and accents. Shchukin not only lists formulas and theorems, but also illustrates them with real examples from engineering practice. This allows the reader not only to understand how probability models work, but also to see how they can be used to solve specific problems, such as risk assessment, process optimization, and decision-making under uncertainty. One of the main themes of the book is the application of probabilistic methods in various fields of engineering, including mechanical, electrical, and construction. Shchukin examines in detail how theoretical concepts can be used to analyze the reliability of systems, design sustainable structures and assess the likelihood of emergency situations. This makes the book particularly relevant to those working in areas where accuracy and reliability are paramount.. The book will be of interest not only to engineers, but also to students of technical specialties who want to deepen their knowledge in the field of statistics and probability theory. It can also attract the attention of researchers engaged in data analysis and modeling, because the author shares not only theoretical aspects, but also practical tools that can be used in scientific work. Writing style A. Shchukin is clear and logical . It avoids overly complex mathematical formulations, which makes the material available to a wide audience. Each chapter ends with practical tasks, which allows the reader to consolidate the knowledge gained and apply it in practice. This approach makes the book not just a textbook, but a real tool for self-education. The book “Probability Theory and Its Application in Engineering Calculations” is not just a collection of theoretical knowledge, but a practical guide that will help readers learn how to use probability methods to solve real problems. It will be an excellent addition to the library of any engineer or student seeking professional growth and development. If you are looking for a book that combines theory and practice, and want to learn how to apply probabilistic methods in your work, then this publication should definitely be on your shelf.
