The End 2016 A-To-Z feels like the one where I figured out how to do these things. Normal Numbers, this entry, is a piece that felt like I was making the breakthrough I wanted. Some of it is about the technical definition of normal numbers. But I also got into why normal numbers are interesting. Mysterious, even, in the medieval-theologist sense of of mystery. Almost every number is normal, but we only know a handful of normal numbers. So far as I’m aware, though, we don’t know of any number that’s interesting in its own right that’s also normal. It seems like a paradox.
