By one of our most imaginative mathematicians, a mind-expanding trip through the beauty--and the mysteries--of infinity "Cheng does a great service by showing us non-mathematician schlubs how real mathematical creativity works."-- Wall Street Journal 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? MathematicianEugenia Cheng has some answers. Whether pondering why some numbers are uncountable, or why infinity plus one isnot the same asone plus infinity, Cheng takes readers on a staggering journey from math at its most elemental to itsloftiestabstractions. Along the way she considers how you could use a cheeseboard to help plan a dinner part for 7 billion people, what it would mean to make a chicken-sandwichsandwich, and whether you could create infinite cookies from a finite ball of dough (the math saysyes!). An essentialbook on the universe's biggestpossible topic,Beyond Infinitywill beguile and bewitch you, and show how onelittlesymbol-- ∞ --can hold the biggest idea of all.
