Lewis Carroll's writings have inspired and entertained generations of readers, but now his forgotten achievements in the world of numbers are finally brought to light by highly acclaimed author and mathematician Robin Wilson. Here Wilson explores the singular imagination of Charles Lutwidge Dodgson - known to millions around the world as Lewis Carroll - the creator of Alice's Adventures in Wonderland and Through the Looking-Glass. Lewis Carroll in Numberland shows how this incredible mind was not limited to the exuberant fantasy and word play of his chidren's books which brim with mathematical allusions - arithmetical, geometrical, logical and mechanical. Dodgson's exceptional talent as a mathematician won him the Christ Church Mathematical Lectureship at Oxford, a position he held for over twenty-six years. During this time he published extensively and brilliantly in the traditional fields of geometry, logic and algebra. Wilson's passionate celebration of Dodgson's mathematical achievements reveals that his work in numbers went far beyond the purely academic. We are taken inside the mind of a man who turned his mathematical genius to the study of voting patterns, to the design of tennis tournaments and even to the prolific creation and popularization of imaginative, numerical puzzles.
