How massive are the cosmos, exactly? What is the total amount of digits? Is it true that Infinity plus one is the same as one plus Infinity? Such concerns arise in the brains of both young children and our finest thinkers. And they are all asking the same question: what is the definition of Infinity?

In Beyond Infinity, Eugenia Cheng takes us on a mind-boggling trip through mathematics, starting with its most fundamental concepts and progressing to its most abstract abstractions. A few of the topics she discusses are how to plan an international dinner party with the help of a chessboard, build an Asian chicken sandwich, and manufacture endless cookies from a finite ball of dough. Beyond Infinity demonstrates how a small sign can hold the most important concept of all.
