Given an integer $q\ge 2$, we say that an irrational number is {\it $q$-normal} if, as we examine its base $q$ expansion, we find that any sequence of $k$ digits appears with a frequency of $1/q^k$. We will show how one can use the local chaos and global regularity both inherent to the factorization of integers in order to create large families of normal numbers.

Joint work with Imre K\'atai (Eotvos Lorand University, Hungary).
