The book "Mathematics of the Craftsman: Arithmetic and Geometry" is a comprehensive guide to understanding the fundamental principles of mathematics and their practical applications in various fields. The author, a renowned mathematician and educator, presents a unique approach to learning mathematics that emphasizes the importance of developing a personal paradigm for perceiving the technological process of developing modern knowledge. This paradigm is based on the idea that the survival of humanity and the unity of people in a warring state depend on our ability to adapt and evolve with technology. The book begins by exploring the history of mathematics and its impact on human civilization, highlighting the key milestones and breakthroughs that have shaped our understanding of the subject today. It then delves into the basics of arithmetic and geometry, providing clear and concise explanations of concepts such as numbers, fractions, decimals, percentages, ratios, proportions, angles, shapes, and measurements. The author emphasizes the importance of mastering these fundamentals, as they form the foundation for advanced mathematical concepts and real-world applications. As the reader progresses through the book, they will learn about the evolution of mathematics from ancient times to the present day, including the contributions of famous mathematicians and scientists such as Euclid, Archimedes, Isaac Newton, and Albert Einstein. The author also discusses the role of mathematics in modern technology, including computer science, engineering, physics, and economics.
