The golden ratio is a mathematical concept often found in nature and art, representing an ideal proportion. It is approximately equal to 1.618 and is denoted by the Greek letter phi (φ). This ratio occurs when a line is divided into two parts, such that the whole length divided by the longer part is equal to the longer part divided by the shorter part.
What is the Golden Ratio?
The golden ratio is a unique mathematical relationship that has fascinated mathematicians, artists, and architects for centuries. It is often seen as a symbol of beauty and harmony due to its frequent appearance in nature, art, and architecture.
- Mathematical Definition: If a line is divided into two parts, A and B, the golden ratio is achieved when (A + B) / A = A / B = φ (approximately 1.618).
- Symbol: Represented by the Greek letter φ (phi).
- Decimal Approximation: 1.618033988749895…
How is the Golden Ratio Used in Art and Architecture?
