Golden Ratio
The golden ratio is an irrational mathematical constant, approximately 1.6180339887 and denoted by the Greek letter φ (phi), defined by the geometric relationship in which a line segment is divided such that the ratio of the whole to the longer part equals the ratio of the longer part to the shorter.
Overview
It satisfies the algebraic equation φ² = φ + 1 and is intimately related to the Fibonacci sequence, whose consecutive term ratios converge toward φ; in geometry it appears in the construction of regular pentagons, pentagrams, and Platonic solids, and was studied extensively by Euclid under the name 'extreme and mean ratio.'
Why it matters
The golden ratio serves as a rare conceptual bridge linking abstract mathematics, natural science, and the visual arts — φ emerges in the arrangement of seeds in sunflowers, tree branching patterns, and shell spirals, while architects and artists from ancient Greece through the Renaissance have sought to incorporate it as a principle of fundamental proportion and visual harmony.
