Entertaining mathematics. Perelman Ya.I.

“Entertaining mathematics” - the legendary work of Jacob Perelman, which is rightfully considered the forerunner of the modern “scientific”. First published in 1927, she withstood dozens of reprints and to this day has not lost its relevance. With the examples of the works of the immortal classics of Herbert Wells, Jules Verne, Kurda Lasswitz, the author talks about the relativity of space and time, about heavenly mechanics and a mathematical analysis of games, the fourth dimension and large numbers. The book is addressed to both adolescents and adults who decided to interest their children with accurate sciences.
