Resting at the heart of modern mathematics is the concept of infinite sets. It's a notoriously difficult concept, and in my own evaluation, it strikes me as logically contradictory.
So, I accept an invitation to talk with an ex-mathematician who specializes in set theory - perhaps he can set me straight and help me understand the basic ways of thinking about these "completed infinities."
