Shortly after 2:29 p.m. on Tuesday, August 14, 2012, the population of the United States reached exactly 314,159,265. That’s 100 million times pi, or π x 108 Americans. No word yet as to whether or not that population is to be considered rational.
"Pilish" is a style of writing in which the lengths of consecutive words match the digits of pi, usually in the form of a poem or rhyme. Cadaeic Cadenza is a short story noteworthy in that it corresponds to the first 3,835 digits of the number. It begins "One: A Poem - A Raven: Midnights so dreary…", or 3: 1 4 - 1 5: 9 2 6…
In 1897, in a vain attempt to “square the circle” (an impossible task), the lower house of the Indiana State Legislature moved to supplant scientific truth by majority rule, passing a bill announcing that, hence forth, “the ratio of the diameter and circumference [of a circle] is as five-fourths to four” - in other words, pi is equal to exactly 3.2. Though the bill passed general assembly, it was tabled once it reached a slightly more scrupulous Senate committee.
The record for calculating pi currently stands at ten trillion decimal digits. The calculation took 191 days to complete using a custom-built desktop computer attached to 44 terabytes of external storage. The number itself, stored as an uncompressed text file, is over 16.6 terabytes. This calculation was a followup by the same two individuals who, a year prior, set the previous record of five trillion digits.
