Phi is an irrational mathematical constant, approximately 1.618.., and is often denoted by the Greek letter φ. Other commonly used names for Phi are: Golden Mean, Extreme and Mean Ratio, Divine Proportion and Golden Ratio.
In navigation the Phi symbol denotes latitude; it describes the work function in electronics; in psychoanalysis it represents the phallus; and in philosophy it stands for a generic act.
Phi was named for the Greek architect, mathematician, painter and sculptor, Pheidias, who used the divine proportion in his architecture. Because of the relationship between the Golden Ratio and the pentagon, some scholars have claimed that φ was known as early as the time of the Babylonians.
But this “Phi” — the Divine Proportion, the Golden Mean, the Golden Ratio — appears everywhere in nature, primarily in three ways — spirals, pentagrams, and phyllotaxis, the arrangement of leaves around a stem.
Phi (/faɪ/; uppercase Φ, lowercase φ or ϕ; Ancient Greek: ϕεῖ pheî [pʰéî̯]; Modern Greek: φι fi [fi]) is the 21st letter of the Greek alphabet.
Phi ( Φ = 1.618033988749895… ), most often pronounced fi like “fly,” is simply an irrational number like pi ( p = 3.14159265358979… ), but one with many unusual mathematical properties. Unlike pi, which is a transcendental number, phi is the solution to a quadratic equation.
Protected health information (PHI), also referred to as personal health information, is the demographic information, medical histories, test and laboratory results, mental health conditions, insurance information and other data that a healthcare professional collects to identify an individual and determine appropriate ...
The symbol ("phi") was apparently first used by American mathematician Mark Barr at the beginning of the 20th century in commemoration of the Greek sculptor Phidias (ca. 490-430 BC), who a number of art historians claim made extensive use of the golden ratio in his works (Livio 2002, pp.
where the Greek letter phi ( or ) denotes the golden ratio. The constant satisfies the quadratic equation and is an irrational number with a value of. 1.618033988749.... The golden ratio was called the extreme and mean ratio by Euclid, and the divine proportion by Luca Pacioli, and also goes by several other names.
Phenyl group (Φ), a functional group in organic chemistry.
As Phi and it's reciprocal phi are 1.618 and 0.618, respectively, we see that this Holy Name of God intrinsically represents a set of ratios that reflect the golden ratio, or the Divine proportion, that we see all throughout His creation. The Hebrew word for “when they were created” is BeHebaram.
Phi (Φ,φ) is called Phi after the famous Greek sculptor Phidias (5th century B.C.), the creator of towering architectural landmarks like the Parthenon in Athens.
The inverse of Phi, 1/Phi, is commonly referred to as the “lowercase phi” (Both symbols for Phi and phi are at top of page). Any division of two quantities that results in Phi or phi yields the Golden Ratio.
PHI stands for Protected Health Information. The HIPAA Privacy Rule provides federal protections for personal health information held by covered entities and gives patients an array of rights with respect to that information.
Examples of PHI
Addresses — In particular, anything more specific than state, including street address, city, county, precinct, and in most cases zip code, and their equivalent geocodes. Dates — Including birth, discharge, admittance, and death dates. Biometric identifiers — including finger and voice prints.
Introduction to selected problems of enduring philosophical importance, including such topics as the nature of morality, knowledge, human freedom, and the existence of God. Content varies with different sections. Credit is not allowed for both PHI 205 and PHI 210.
Pi can be found in the ratio of the circumference to the diameter of any perfect circle. The Golden Ratio or Phi can be found in the ratio of the arm of a five pointed star to the side of the pentagon at its center.
Alpha Phi is the 4th oldest National Women's sorority. Alpha Phi is one of only 3 international sororities. Alpha Phi has over 175 active alumnae chapters. Alpha Phi is pronounced Alpha "fee" (long "e") not "fie" because "Alpha" is a vowel and "Phi" is pronounced "fee" when it follows a vowel.
The Golden Ratio (phi = φ) is often called The Most Beautiful Number In The Universe. The reason φ is so extraordinary is because it can be visualized almost everywhere, starting from geometry to the human body itself! The Renaissance Artists called this “The Divine Proportion” or “The Golden Ratio”.
The First Fraternity - Phi Beta Kappa
They chose the Greek letters Phi Beta Kappa because those letters represented their secret motto: Philosophia Bios Kybernethes, which roughly translates to “Philosophy is the guide to life.”
golden ratio, also known as the golden section, golden mean, or divine proportion, in mathematics, the irrational number (1 + Square root of√5)/2, often denoted by the Greek letter ϕ or τ, which is approximately equal to 1.618.
