Laboratory Workshop on Physics . Fluctuations, waves, structure of matter", written by a team of authors led by I. A. Avenarius, Afanasiev and Belova, is a unique textbook that will become an indispensable assistant for students and teachers studying physics at the level of higher education. This edition is not just a set of laboratory tasks, but a whole system that allows a deeper understanding of the main physical phenomena, such as vibrations, waves and the structure of matter. On the pages of the book, readers will find carefully thought-out experiments that will help not only to consolidate theoretical knowledge, but also to develop practical skills in working with physical devices. Each task is accompanied by detailed instructions, which makes the learning process more accessible and fun. The authors pay special attention to ensuring that each experiment is understandable and logical, which allows students to independently investigate physical patterns and draw conclusions based on the obtained data. The book will be of interest not only to students of physical and mathematical specialties, but also to everyone who is fond of natural sciences. It is suitable for both beginners and more experienced readers who want to deepen their knowledge in the field of physics. Teachers will find in this workshop useful materials for organizing laboratory classes, as well as ideas for independent work of students . The topics raised in the book cover a wide range of issues related to oscillations and waves, which is the basis of many physical phenomena. Readers will be able to learn about the different types of oscillations, their characteristics and applications in real life. Also, the book touches on issues related to the structure of matter, which allows you to better understand how the world around us is arranged. These topics are not only relevant, but also cause interest among young people seeking to understand the complex processes taking place in nature. The style of the authors is distinguished by clarity and accessibility of the presentation, which makes the material easy to perceive. and . A. Avenarius, known for his work in the field of physics and teaching methods, together with other authors creates an atmosphere in which learning becomes not only useful, but also fascinating.
