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)
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!
