Yakov Perelman proves that geometry is not at all a "desk" science created to torment schoolchildren. Each section of this book contains tasks and stories that will help you not only easily memorize complex formulas, but also put them into practice.
Perelman examines not only well-known theorems, but also practical everyday issues. How can I measure the circumference of a glass without a ruler and a centimeter, or count how many stars are reflected on the surface of a river? Why do wooden barrels have bulging sides?
You will begin to enjoy science and begin to notice the laws of geometry everywhere: on the street, at home, and even in fiction! In "Entertaining Geometry," for example, it tells about the geometric mistakes Swift and Pushkin made in their books.
The book will be interesting not only for children, but also for adults, and the illustrations and diagrams will help to better understand and assimilate the material.
