"Time of Variables" is a fun book about mathematics all around us. Twenty-eight fascinating stories devoted to various aspects of mathematics are accompanied by funny author's drawings. Mathematical analysis for Orlin is a universal language capable of expressing everything that we encounter every day - love, risk, time and, most importantly, constant change.

The theme of the movement of time is reflected in the titles of the book's sections - "Moments" and "Eternities", and in its characters - from Sherlock Holmes to Mark Twain and David Foster Wallace. With his characteristic humor and ingenuity, Orlin reveals the connections between mathematical analysis, art, literature and his beloved dog named Elvis.

The author of the sensational "Mathematics with Silly Pictures" also aims in this book not only to captivate the reader with his favorite subject, but to make us wiser and more thoughtful.
