Imagine something small enough to fit in your head but too large to fit in the world - or even the universe. What would you call it? And what would it be? How about...infinity?
In Beyond Infinity, musician, chef, and mathematician Eugenia Cheng answers this question by taking listeners on a startling journey from math at its most elemental to its loftiest abstractions. Beginning with the classic thought experiment of Hilbert's hotel - the place where you can (almost) always find a room, if you don't mind being moved from room to room over the course of the night - she explores the wild and woolly world of the infinitely large and the infinitely small. Along the way she considers weighty questions like why some numbers are uncountable or why infinity plus one is not the same as one plus infinity. She finds insight in some unlikely examples: planning a dinner party for seven billion people using a chessboard, making a chicken-sandwich sandwich, and creating infinite cookies from a finite ball of dough all tell you more about math than you could have imagined.
An irresistible book on the universe's biggest possible topic, Beyond Infinity will beguile and bewitch you and show all of us how one little symbol - ∞ - can hold the biggest idea of all.
"The idea of infinity is one of the most perplexing things in mathematics, and the most fun. Eugenia Cheng's Beyond Infinity is a spirited and friendly guide - appealingly down to earth about math that's extremely far out." (Jordan Ellenberg, author of How Not to Be Wrong and professor of mathematics at University of Wisconsin-Madison)
