 The Golden Spiral above is created by making adjacent squares of Fibonacci dimensions (I did mine using a scale of 2). An arc is then made across each square.       This spiral is called equiangular, because for each quarter turn (90 degrees or pi/2), the spiral increases by a factor of phi. That is, if you take one point, and then a second point one-quarter of a turn away from it, the second point is phi times farther from the center than the first point. All equiangular, or logarithimic spirals increase by a factor of phi.       When the golden spiral is graphed on a polar axis, it looks like the image above. The coordinates of a point, such as A, are written as . Points can also be written in terms of . In these instances, and . If you combine these two equations, you end up with . | home | introduction | constructions | biology | aesthetics | games | about | contact | Created by Andi, Mel, and Shuj for Thinkquest Internet Challenge 2000
