The name of Yakov Perelman is familiar to several generations of readers. His books have become classics of popular science literature due to his rare ability to combine the accuracy of scientific knowledge with a keen interest in the world around him. Instead of dry definitions, Perelman suggests a research path in which every observation becomes a reason for reflection.This collection includes three works that form the basis of his popular science legacy. "Entertaining arithmetic" shows that the world of numbers is much richer than the usual school calculations. "Entertaining geometry" reveals unexpected properties of space and helps to look at the surrounding objects through the eyes of a researcher. "Entertaining mechanics" explains the laws of motion and operation of the mechanisms that accompany man from antiquity to the present.The book allows you to see science as a part of everyday life and reminds you that any discovery begins with curiosity. The collection will be interesting to anyone who appreciates clear thinking, intellectual tasks and the pleasure of finding answers on their own.
