A Guide to Infinity

“Math is rarely this precise and this readable at the same time. A gem for anyone who’s ever been curious about the infinite.”—Steven Strogatz, author of Infinite Powers“A delightful book about the fundamental concept of infinity! With remarkable clarity, Ed Scheinerman invites readers to explore the many paths for approaching the infinite.”—Avi Wigderson, Institute for Advanced Study, Princeton“A wonderfully well-presented set of explorations of infinity. Using only mathematics at the precalculus level, Professor Scheinerman enables the reader to effectively think about, and meaningfully work with, infinity from a variety of perspectives: algebraic, geometric, and set-theoretic.”—Susan Jane Colley, Andrew and Pauline Delaney Professor of Mathematics Emerita, Oberlin College“Ed Scheinerman succeeds in explaining the mathematical concept of infinity in its many guises, using only basic mathematical background. This is a beautiful description of a fascinating topic written by a superb expositor.”—Noga Alon, Princeton University

Edward R. Scheinerman is professor of applied mathematics and statistics and a vice dean at the Whiting School of Engineering, Johns Hopkins University. He is the author of The Mathematics Lover’s Companion.
