“A poetic and profound meditation on the mathematical imagination.” —The Christian Science Monitor

“[A] quizzing, quizzical little book...The window which Mazur cuts into the world of imaginary numbers is just as exciting, and almost as provocative, as anything in Phillip Pullman.” —The Observer (London)

“Through anecdotes, poetry, and philosophy, Mazur...makes a delightful case for the pleasures of abstract thought.” —New Scientist

“This absorbing and in itself most imaginative book lies in the grand tradition of explanations of what mathematical imagination is...and will appeal particularly to lovers of literature.” —John Hollander

“Barry Mazur's Imagining Numbers is quite literally a charming book; it has brought even me, in a dazed state, to the brink of mathematical play.” —Richard Wilbur, author of Mayflies: New Poems and Translations
