The Fibonacci Spiral

Fibonacci spiral

by Dave on May 18, 2010

Nature is full of spirals.  In the header of this blog I’ve chosen three from different sources.  The first is a fiddlehead fern, before it unclenches into its mature state.  The second is a prehistoric petroglyph, showing an ancient human fascination with spirals.  The third is a nautilus shell, which gives us an example of a Fibonacci spiral.

Leonardo Fibonacci was an Italian mathematician who, among other things, brought Hindu-Arabic arithmetic to the West.  Here are a few links for more information.
