Resumen
There are many different types of spirals1; these include Archimedean, hyperbolic, and logarithmic (or equiangular) spirals. I suspect that nearly everyone has heard of the “golden ratio,” the Fibonacci sequence, and the related golden rectangles and golden spirals (often referred to in a botanical context, especially in connection with the arrangement of seeds in sunflower heads).
It is often claimed that golden rectangles and spirals can be found in many places, fitting (suitably cropped) pictures of the Parthenon in Athens, the human body, works of art (such as the Vitruvian Man by da Vinci), shells, spiral galaxies, hurricanes, curling waves, and so on.
