Phi (/faÉª/; uppercase Ï, lowercase Ï or Ï; Ancient Greek: ÏÎµá¿ pheÃ®; Modern Greek: ÏÎ¹ fi ) is the 21st letter of the Greek alphabet. In Ancient Greek, it represented an aspirated voiceless bilabial plosive (), which was the origin of its usual romanization as ph.
Phi, like Pi, is a ratio defined by a geometric construction. Just as pi (p) is the ratio of the circumference of a circle to its diameter, phi ( ) is simply the ratio of the line segments that result when a line is divided in one very special and unique way. Divide a line so that: to the length of the smaller line segment (C).
