"Non-Euclidean Geometry" is an outstanding work of B. A. Rosenfeld, who immerses the reader in the fascinating world of mathematical thought and philosophy This book will be a real discovery not only for students and teachers of mathematics, but also for everyone who is interested in deep concepts of space and time. Rosenfeld, known for his in-depth research in geometry and its foundations, offers the reader a unique opportunity to look at the world from a perspective different from the usual Euclidean geometry. In Non-Euclidean Geometry, the author explores various systems of geometry that go beyond classical representations. He examines hyperbolic and elliptical geometry, raising important questions about the nature of space and its perception. The reader will be able to learn how non-Euclidean geometries affect our understanding of physics, as well as how they have become the basis for many modern scientific theories. This book is not only informative, but also provocative, forcing us to think about how we perceive the world around us. Who can like this work? First of all, it will be interesting for students and graduate students studying mathematics, physics or philosophy . However, the wider audience, including science lovers and just curious people, will find a lot of fascinating things in the book. If you’ve ever wondered what alternative ideas of space are, or want to expand your horizons in mathematics, Non-Euclidean Geometry is what you need. The topics raised in the book go far beyond simple mathematical concepts. Rosenfeld touches on the philosophical aspects of geometry, discussing how different systems can influence our understanding of reality. He also explores the historical context of the development of non-Euclidean geometries, recounting the great minds such as Lobachevsky and Riemann who made revolutionary discoveries in this field. The reader will be able to see how these ideas have evolved and how they have influenced modern science. Rosenfeld's style is clear and accessible, making complex concepts understandable even to those who are not experts in mathematics. His ability to explain abstract ideas in simple language makes the book attractive to a wide audience. B. A. Rosenfeld is also known for his other works, such as Fundamentals of Geometry and Mathematical Logic, which are also noteworthy and can complement the understanding of topics discussed in Non-Euclidean Geometry. This book is not just a textbook, but a real intellectual adventure story in which the reader becomes an accomplice in finding answers to important questions. It inspires reflection and encourages further study of mathematics and philosophy. If you are looking for a book that will not only expand your knowledge, but also make you think about the nature of reality, Non-Euclidean Geometry A. Rosenfeld is exactly the way to go.
