divine proportion

The divine proportion, often represented by the Greek letter phi (Φ), is a special ratio approximately equal to 1.618. It appears in nature, art, and architecture, symbolizing harmony and beauty. When a line is divided into two parts, the longer part divided by the shorter is equal to the whole line divided by the longer part. This ratio creates pleasing aesthetics and has been used by artists like Leonardo da Vinci and architects in designs, suggesting a deeper sense of balance and proportion that resonates with human perception and nature.
