# Definition of Golden Ratio

The golden ratio is the number $\varphi = \dfrac{1 + \sqrt{5}}{2} = 1.6180339887 \dots$.

It is found when we divide a line up into two parts so that the ratio of the longer part to the smaller part is equal to the ratio of the whole length to the longer part.

The golden ratio features in the works of some artists and architects such as Le Corbusier and Dali as it is believed to provide a pleasing appearance. It also appears in some patterns in nature such as the spirals in the nautilus shell and the spirals formed by emerging fern leaves.
