How can anything be bigger than infinite? Shouldn't ∞ +1= ∞ What about ∞ x ∞? Is that like ∞2? What about ∞∞? We'll spend the night working through the ideas of Georg Cantor, the father of modern set theory. We'll reexamine the concepts of number and size, and head off towards the infinite, where careful analysis will light the way. We'll develop a real way to measure infinite sets.
