WHAT DO YOU KNOW ABOUT PI?
Maybe you would say it’s a handy constant, helpful when trying to figure out a circumference or area. Maybe you’d say it’s irrational and transcendental. Maybe you’d say you know the first five digits, 3.1415 (or maybe you even know the first 10 or 15 or more). But whether you know the first 5 or the first 5000 digits, there are a lot of questions we can ask about the digits that make up pi.
We could wonder about whether a specific string of digits (such as your birthday) exists somewhere in pi or even if all possible finite strings of digits appear somewhere in pi.
