The Fibonacci series emerges again, and this time its wearing quite an impending and ominous cloak: the hurricane Irene. Here’s a satellite image of the hurricane looming over the Eastern coast of US – with Fibonacci spiral overlay.
Note that the eye of the hurricane is a bit off-center – which calls for a disclaimer. It’s not difficult to find an approximation of any mathematical relation in nature which is replete with myriad shapes. There’s no divine, mystical governing principle that guides the shape and size of objects.
Having said that, there are situations in which a Fibonacci (and other) series may arise naturally. See my earlier post Nature by Numbers for some interesting examples.
