For those who can not speak Greek, the Greek letter π is one of the most important letters globally. We did our research in Wikipedia and here is some useful info:
Pi (/ˈpaɪ/; Greek: [pi], uppercase Π, lowercase π) is the sixteenth letter of the Greek alphabet, representing [p].
The letter “π” is the first letter of the Greek words “περιφέρεια” ‘periphery’ and “περίμετρος” ‘perimeter’, i.e. the circumference.
The lower-case letter π is used as a symbol for the mathematical real transcendental (and thus irrational) constant π ≈ 3.1415926535897932384626433832795028841971…, the ratio of a circle’s circumference to its diameter in Euclidean geometry.
On top of all the reasons above, we recently found another reason why we adore the Greek letter Π: the region of Peloponnese used the word Π in the Mythical Peloponnese 3D Animation Video, where a 3D Π represent the Peloponnese’s logo!
The outcome was amazing (!) exemplified by the fact that the team behind the advertisement got the Silver award in the Tourism Awards 2015 (Toposophy, Atcom Business Unit for the Mythical Peloponnese 3D Animation Video). The 3D logo was developed by Mindworks Interactive. Well done all!
Watch the video and surely you will also become a fan of the Greek letter π!
