Last January, I was innocently sitting in class, minding my own business, when a fellow student — a well-meaning individual with a wife and a baby and a dog — announced that infinity is such a poorly defined and poorly understood idea that it really symbolizes everything truly unknowable and…something something something pray about it. (That’s actually what I heard. Sometimes my ears turn off in self-defense. I imagine the final movement of Shostakovitch’s 5th for a few minutes and then rejoin the conversation.)
Thankfully, infinity is a hot topic these days, and the next time this comes up, I have a YouTube playlist ready.
Thank you, John Green, for helping to make set theory so unbelievably popular.
