In my message about pi having lots of weird digits, I wanted to know if pi contained every finite string of digits. Is the set of all such numbers which have this property special? Is there a name for it. I am just curious because it always seems that mathematicians have considered so really oddball questions.

No one knows if the decimal expansion of pi contains every finite string of digits and no one ever will because only a finite number of digits may be produced. Topics to look up for study include waiting times and expecta- tions. The expected number decimal positions (starting at any unknown value) before the onset of a string of 999 nines is 10^999 and then there is only a reasonable probability (0.632) that the desired string will be found in the 10^999 digits. A billion centuries is a small time interval compared to the time it would take to try this out, given the best of modern comput- ing speed.
