Midnights so dreary, tired and weary,
Silently pondering volumes extolling all by-now obsolete lore ...."
~ Mike Keith, “Cadaeic Cadenza” (1996)
And how many digits can you rattle off by memory? Mathematician and software engineer, Keith created a short story wherein the lengths of the successive words spell out the digits of pi, with a ten-letter word representing each zero. Nearly 4 thousand digits of pi show up! The story’s protagonist, discovering that all of the books on his shelves have been translated into this constraint, must figure out what has happened! π 𝜋 𝛑 𝝅 𝞹 ℼ
A tartan for today's special date, March 14th, also known as Pi Day, for the transcendental number, starting with the digits forming today's date (in the month/day/year system) = 3.14159 ...
Recall that pi is the ratio of a circle’s circumference to its diameter.
This tartan "3.141592653 Pi Day" an unofficial tartan, was designed to mark the ultimate Pi day which occurred in year 2015, wherein the American dating system, Pi day officially occurred at
3-14-15, 9:26:53 A.M.
taking the first 10 digits of pi.
The designer used the various colours to signify the digits, starting with the special case of a wide red line to signify the whole number "3." See if you can see the intended sequence.
Pi has been studied by the human race for almost 4,000 years. By 2000 B.C., Babylonians established the constant circle ratio as 3-1/8 or 3.125. The ancient Egyptians arrived at a slightly different value of 3-1/7 or 3.143.
One of the earliest known records of pi was written by an Egyptian scribe named Ahmes (c. 1650 B.C.) on what is now known as the Rhind Papyrus. He was off by less than 1% of the modern approximation of pi (3.141592).
For those who like to display their memory prowess by reciting pi digits from memory ...
The most decimal places of Pi memorised is 70,030, and was achieved in October 21, 2015 by Suresh Kumar Sharma.
The recall took slightly more than 17 hours!
