Have a Pi, Maybe Two Today

March 14, 2017 by GµårÐïåñ
The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi" (/paɪ/).

The number π is a mathematical constant, the ratio of a circle’s circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter “π” since the mid-18th century, though it is also sometimes spelled out as “pi” (/paɪ/).


Being an irrational number, π cannot be expressed exactly as a fraction (equivalently, its decimal representation never ends and never settles into a permanent repeating pattern). Still, fractions such as 22/7 and other rational numbers are commonly used to approximate π. The digits appear to be randomly distributed. In particular, the digit sequence of π is conjectured to satisfy a specific kind of statistical randomness, but to date no proof of this has been discovered. Also, π is a transcendental number, i.e., a number that is not the root of any non-zero polynomial having rational coefficients. This transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge.

deviantArt profile for GµårÐïåñ on deviantArt

Facebook i have made a personal choice after their "name policy" witch hunt which repeats every 2 years it seems at the whim of the "bully mob" (even when they make you jump through hoops and verify you), to just quit it and be done with it, they are not worth my time. I don't need it, I don't miss it, in fact it has made my life more productive and void of gross hate, vitriol and drivel. To those who say they can't stay in touch if I am not on there, if you can't reach me because I am not on Facebook, then you are not trying AT ALL - therefore, good riddance.
