So, I've started a new blog, Infinity Plus One, discussing more advanced math topics, but aimed at a lay audience. I thought this forum looked like a place where people interested in this kind of resource (or who know those who would be) congregate. So, here are links for my first two posts. I hope you enjoy them. First post: Infinity plus one Second post: The size of infinity

However, I disagree that infinity is not a number in any way. There are multiple contexts in which infinity is a perfectly good number and a blog discussing advanced math topics is likely to cover these.

I did make a slight mistake, however. I forget the name of the system but it is the real numbers with infinity attached, rather like the closure of the real line. I think it's called the extended real line or something of that nature. Dan

The extended real line doesn't include a number "infinity". It's more like a set of names for limit points.
