The Fibonacci spiral is considered a logarithmic spiral, which are found everywhere in nature. Jakob Bernouli, a mathematician from a great family of brilliant people, called the logarithmic spiral spira mirabilis, or "the Miraculous Spiral," so called because the size increases but its shape is unaltered with each successive curve. This kind of spiral shows up in shells, in hurricanes, in flowers and even in the human body!
Logarithmic spiral: "A logarithmic spiral, equiangular spiral or growth spiral is a special kind of spiral curve which often appears in nature." // Seen in: nautilus shell, Romanesco broccoli, weather patterns, space (spiral galaxies)
Rafael Araujo – The Colossal Shop.. At a technology-free drafting table he deftly renders the motion and subtle mathematical brilliance of nature with a pencil, ruler and protractor." Araujo creates an imagined mathematical framework of three dimensional space where butterflies take flight and the logarithmic spirals of shells swirl into existence.."
