“Squares and logarithms” is a fascinating work written by the famous Russian mathematician and popularizer of science, Valentin Markushevich .. This book is not just a textbook, but a real intellectual odyssey, in which the author masterfully combines mathematics with philosophy, art and everyday life. If you have ever thought about how mathematics permeates all aspects of our existence, then this work will be a real discovery for you. The book covers a wide range of topics, ranging from the basics of geometry to more complex concepts such as logarithms and their application in various fields. Markusiewicz is not limited to dry formulas and theorems; he seeks to show the reader how mathematics can be beautiful and inspiring. Each chapter is filled with real-life examples, making the material accessible and understandable even to those who are not professional mathematicians. "Squares and logarithms" will be interesting for both schoolchildren and adults who want to refresh their knowledge or simply expand their horizons. If you like to solve puzzles, look for connections between different phenomena or just want to understand how the world around you works, this book will become your faithful companion. It is especially suitable for those who are interested in mathematics, physics, as well as those who want to develop critical thinking and analytical abilities. One of the key topics raised in the book is the relationship between mathematical concepts and their practical application. Markushevich emphasizes that mathematics is not just a set of formulas, but a language spoken by nature itself. It shows how logarithms help solve real-world problems, such as in economics, biology, and even the arts. The reader will be able to see how abstract mathematical ideas can be applied to solve specific problems, which makes the book especially relevant in the modern world. Markuevi's style is easy and accessible. He is able to explain complex things in simple language, which makes his work attractive to a wide audience. His previous works, such as Mathematics for All and How to Understand Mathematics, have also been popularized through this approach. In "Squares and Logarithms", the author continues this tradition, adding elements of fascinating narrative and personal reflection, which makes reading not only informative, but also pleasant. The book also touches on the philosophical aspects of mathematics, raising questions about how we perceive the world and what roles numbers and shapes play in our perception of reality. This makes "Squares and Logarithms" not just a textbook, but a real reflection on life, science and art. Readers interested in the philosophy, culture and history of science will find in it a lot of interesting and inspiring. If you are looking for a book that will not only expand your mathematical horizons, but also make you think about deeper issues, “Squares and Logarithms” is the perfect choice. This work will be a great addition to your library, as well as give you new ideas and inspiration for further study of mathematics and its connection with the world around you. Do not miss the opportunity to immerse yourself in the world of numbers and forms with Valentin Markushevich - you will not regret it!
