The Basics of Physics . T. 2 Fluctuations and Waves. Quantum Physics . Physics of the Core and Elementary Particles" by Yavorsky B. M. and Pinsky A. A. It is a fascinating and deep dive into the world of physical phenomena that form the basis of our understanding of the universe. This volume is a continuation of the first part and covers key topics such as oscillations and waves, quantum physics, as well as nuclear and elementary particle physics. If you are interested in physics, want to expand your knowledge or just looking for high-quality educational material, then this book will be a real find for you. The second volume of "Fundamentals of Physics" offers the reader a unique opportunity not only to get acquainted with the theoretical aspects, but also to see how these concepts are applied in real life. The authors, known for their deep knowledge and ability to explain complex topics, emphasize the importance of vibrations and waves in various physical processes. You will learn how sound waves, electromagnetic radiation and mechanical vibrations affect our everyday existence, as well as how they underlie many of the technologies we use today. Quantum physics, one of the most exciting and at the same time complex areas of science, is revealed in the book with special attention. The authors explain the basic principles of quantum mechanics, such as superposition, uncertainty, and quantum entanglement, emphasizing their significance for the modern scientific world. This part of the book will be especially interesting for those who want to understand how quantum phenomena affect the microcosm and how they can be associated with macroscopic phenomena. The physics of the nucleus and elementary particles is another important topic that is dealt with in this volume. Readers will be able to learn about the structure of the atom, the interactions between particles and how modern experiments in high-energy physics help us uncover the mysteries of matter. This part of the book will be especially useful for students and graduate students, as well as anyone interested in the latest achievements in the field of physics. The book will be of interest to both high school students and students studying physics, as well as anyone who wants to deepen their knowledge in this area. It is suitable both for self-study and for use in the educational process. The authors have done a great job to make the material accessible and understandable, which makes this book an ideal tutorial. The style of Yavorsky and Pinsky is distinguished by clarity and logical presentation, which allows the reader to easily assimilate complex concepts. Their previous work, such as "Fundamentals of Physics. T. Mechanics and Thermodynamics” has already won recognition among students and teachers, and this volume will not be an exception. The authors use many examples and tasks, which makes the study of physics not only useful, but also fascinating. The Basics of Physics . T. 2 Fluctuations and Waves. Quantum Physics . Physics of the Core and Elementary Particles” is not just a textbook, but a real encyclopedia of knowledge that will help you understand the world around you more deeply. If you are looking for a high-quality and relevant physics textbook that not only teaches, but also inspires, then this book will become your faithful companion on the way to knowledge. Do not miss the opportunity to discover the amazing world of physics together with Yavorsky and Pinsky!
