Golden ratio

Definition

The golden ratio, often denoted by the Greek letter phi (Φ), is a mathematical ratio approximately equal to 1.618 that is frequently found in nature, art, and architecture. It represents an ideal balance and harmony in composition, leading to aesthetically pleasing proportions. This concept influenced various artistic techniques, architectural designs, and scientific observations during the Renaissance, reflecting a deeper understanding of beauty and symmetry.
