If π is expressed in base 26, then each of its digits can be associated with a letter of the alphabet (0=A, 1=B, … 25=Z). This produces an endless string of letters:

If the digits of π are truly random, then this string “emulates the mythical army of typing monkeys spewing out random letters,” writes Mike Keith. “Among other things, this implies that any text, no matter how long, should eventually appear in the base-26 digits of π.”

In examining the first million letters, Keith has found that the word CONJURE appears at position 246,556. If a carriage return is added after each 2,736 letters, then we have a two-dimensional field in which further words appear, in the style of a word search. Now HOCUS and POCUS appear, intersecting CONJURE (with POCUS in the shape of an L).

When each row is 14,061 digits long, then ALPHA, OMEGA, and GOD appear in a group near position 148,655. And when rows are 13,771 digits long, then DEMON and SATAN appear interlocked near position 255,717. Keith even found the makings of a charming haiku near position 554,766 when rows are 1,058 letters long:

Sun, elk in water;
Oho! For her I’ll try to
Be a hero yet.
