Vital reading is chapter 17 of "At Play With J", by Eugene McDonnell http://www.jsoftware.com/jwiki/At%20Play%20With%20J
Here's my resultant page of notes made back in 2010. Touches on the points in this thread: See: Contact, by Carl Sagan, for a novel pivoting heavily on finding patterns in pi. Piphilology comprises the creation and use of mnemonic techniques to remember a span of digits of the mathematical constant π. The word is a play on Pi itself and the linguistic field of philology. The Indiana Pi Bill, an 1897 attempt by the Indiana state legislature to dictate a solution to the unending decimal problem by legislative fiat. Pi search... http://www.angio.net/pi/piquery http://en.wikipedia.org/wiki/String_searching_algorithm Probability of finding strings in pi http://www.angio.net/pi/whynotpi.html Should the search for meaningful sequences in pi be called perimancy? The Feynman Point: APWJ p136 http://www.jsoftware.com/jwiki/Doc/Articles/Play151 From end of Eugene McDonnell's article: "Before we part, let’s look at a consecutive portion of these digits: (762+i.6){q1000 999999 Hmmm. Well, yes, that’s not too unusual.* In fact, if such strings didn’t occur every now and then, it would argue against randomness." FOOTNOTE: * Eugene has selected the so-called Feynman Point, a six-digit sequence 999999 in the decimal expansion of π to which Richard Feynman (1918-1988) used to draw attention in his lectures to make an instructive joke about what is and what is not perceived as random.
