Golden ratio

Definition

The golden ratio is a mathematical ratio, approximately 1.618, that is often found in nature and is believed to represent aesthetic beauty. This ratio is expressed as $$rac{a+b}{a} = rac{a}{b}$$ where 'a' and 'b' are quantities such that 'a' is the larger one. It connects to visual harmony and balance, influencing how art is composed and evaluated, often perceived as a standard for aesthetic judgment.
