Blog post: ajb: My phone number is in pi!

I found a website that allows you to search the number $latex pi$ for stings of numbers. The Pi Searcher can search for any string of digits (up to length 120) in the first 200 million digits of $latex pi $.

The number $latex pi $ is transcendental meaning it cannot be written as any combination of rational numbers and their n-th roots.

Phone numbers here in Poland are 7 digits and it turns out that there is a  99.995% chance that the Pi Searcher can find it, Of course, if it can't find it then it may well be still in $latex pi $ somewhere,  which is related to the fact that we think it is a normal number.

Anyway my home phone number here in Poland appears 10 times in the first 200 million digits! My IOP number (6 digits) appears 186 times!
