Eugenia Cheng "Beyond Infinity: To the Outer Limits of Mathematics"

How big is the universe? How many numbers are there? And is infinity + 1 the same as 1 + infinity? Such questions occur to young children and our greatest minds. And they are all the same question: What is infinity? Dr. Cheng takes us on a staggering journey from elemental math to its loftiest abstractions. Along the way, she considers how to make infinite music, how to take infinite selfies, how to create infinite cookies from a finite ball of dough, and how one little symbol holds the biggest idea of all.
