In geometry, a [[Golden Spiral]] is a logarithmic spiral whose growth factor is φ, the [[Golden Ratio]]. That is, a golden spiral gets wider (or further from its origin) by a factor of φ for every quarter turn it makes.<ref>[https://en.wikipedia.org/wiki/Golden_spiral Golden | In geometry, a [[Golden Spiral]] is a logarithmic spiral whose growth factor is φ, the [[Golden Ratio]].
