That's not necessarily true and probably is false. What we know about Pi is that it includes an infinite number of elements, but this says nothing about the structure of those elements. An infinitely long random sequence will probably hold every pattern possible (I'm not a mathematician so correct me if I'm wrong) but any structured or repeating sequence doesn't.

This is not true. Pi is probably irrational, which means we know it doesn't repeat itself. However, it is not proven to be normal, so it's a conjecture (but not fact) that it contains every finite sequence of digits at some point.

That's the worst possible typo for this conversation.

Pi is provably irrational, and probably normal!

Damn autocorrect! And it's too late to edit it, too.

Yes, that should say "provably irrational".
