“Fibonacci’s Nautilus” is inspired by the shape of sea shells and the Fibonacci numbers, which appear in various “family trees” and patterns of spirals, leaves and seeds. It is known that the ratio of two successive numbers in Fibonacci’s series is the value called the golden number. Although the Nautilus spiral, as it appears in nature, is not exactly a golden spiral (it does sometimes exhibit dimensions whose proportions come close to the golden number), I have created a sea shell spiral according to the Fibonacci numbers, in view of the fact that the golden ratio is believed to relate to the most visually satisfying of all geometric forms, widely used in art. I think that Nautilus in general is a beautiful example of how the organic and the inorganic fascinatingly intertwine: the living creature (a cephalopod mollusc) is intimately linked to its inorganic shelter (a spiral shell), an organic body is interfaced with an inorganic body. Although my work represents only the inorganic Nautilus, the living Nautilus is indirectly present as well, as every Nautilus shell has or has had an animal within. Therefore, I intended to make a connection between abstract mathematics and the natural world and ultimately between nature and art.
