"[Cheng] does a great service by showing us non-mathematician schlubs how real mathematical creativity works." --Wall Street JournalWhether pondering why some numbers are uncountable, or why infinity + 1 is not the same as 1 + infinity, we've all asked the same question: What is infinity? In Beyond Infinity, Eugenia Cheng takes us on a staggering journey from elemental math to its loftiest abstractions. Along the way she considers how to use a chessboard to plan a worldwide dinner party, how to make a chicken-sandwich sandwich, and how to create infinite cookies from a finite ball of dough. Beyond Infinity shows how this little symbol holds the biggest idea of all.
