phi
Greek math letter
Phi is the twenty-first letter of the Greek alphabet (Φ, φ), used extensively in mathematics and science to represent various quantities.
In mathematics, phi often denotes the golden ratio (approximately 1.618), a proportion found throughout art, architecture, and nature.
In physics, it commonly represents magnetic flux or phase angle.
The architect incorporated phi into the building's proportions. (Capitalized Phi may refer to the Greek letter as a formal symbol or to fraternities and sororities using the letter in their names.)
