(this is an irrational number, like pi or e.But we’re talking about the Fibonacci spiral, which is this:Another approximation is a Fibonacci spiral, which is constructed slightly differently. A Fibonacci spiral starts with a rectangle partitioned into 2 squares. Since the ratio between consecutive Fibonacci numbers approaches the golden ratio as the Fibonacci numbers approach infinity, so too does this spiral get more similar to the previous approximation the more squares are added, as illustrated by the image. And how it’s constructed: you see here the rectangle with added squares, and how a spiral that touches each junction between the squares becomes the Fibonacci spiral. From restaurant owners, to friendly neighbors, and people out for a walk, it seems like just about everyone has a sweet spot for these adorable Turkish cats.
