The book "Mathematical events of the twentieth century", edited by the outstanding mathematician Vladimir Igorevich Arnold, is a fascinating and in-depth analysis of the most significant achievements and discoveries in the field of mathematics that have occurred during the past century. This is not just a collection of facts and dates, but a real intellectual odyssey that immerses the reader in the world of mathematical ideas, theories and their impact on the development of science and technology. The book examines the key events that defined the face of mathematics in the twentieth century. From chaos theory to new directions in algebra and geometry, each of these discoveries not only changed ideas about mathematics, but also had a huge impact on other sciences, such as physics, computer science, and economics. Arnold and his colleagues skillfully connect theoretical concepts with practical applications, which makes the book interesting for both professionals and amateurs. This book will be especially useful for students and teachers of mathematical disciplines, as well as for anyone interested in the history of science and its development. If you are interested in mathematics, want to understand how different theories interact with each other and how they affect the modern world, then the Mathematical Events of the 20th Century will be a real discovery for you. Even if you are not an expert in the field, but just want to expand your horizons and learn more about how mathematics shapes our understanding of the world around us, this book will be an excellent choice. The topics raised in the book cover a wide range: from philosophical questions about the nature of mathematics to practical aspects, such as the application of mathematical models in various fields. The reader will be able to see how mathematics serves not only as a tool for solving problems, but also as a language spoken by nature itself. Arnold, having a unique style of presentation, makes complex ideas accessible and understandable, which allows the reader not only to learn the material, but also to enjoy the learning process. The author, Vladimir Igorevich Arnold, is himself an outstanding figure in the world of mathematics. His work covers many fields, including differential equations, dynamical systems, and topology.
