“From sculptures, paintings, sketches, buildings, monuments, to mathematics- everything can be connected to this magnificent ratio. Leonardo Di Vinci found importance in it, as seen evident in his paintings. Composers produced their music to the length and timing of this Ratio or Section. Nature grows in accordance to this. This is a universal equation to help describe, mathematically, why we like things we do. ” (Da Vinci – Golden Ratio)
