The logarithmic spiral, also known as the growth spiral, was first studied by Descartes in 1638 and Jakob Bernoulli. This spiral often appears in nature. Probably the most important aspect of the logarithmic spiral is that if we increase the angle ø by equal amounts, the distance r from the poles increases in equal ratios.
