Golden Spiral - Spirals in Nature

Spirals in Nature

Approximate logarithmic spirals can occur in nature (for example, the arms of spiral galaxies). It is sometimes stated that spiral galaxies and nautilus shells get wider in the pattern of a golden spiral, and hence are related to both φ and the Fibonacci series. In truth, spiral galaxies and nautilus shells (and many mollusk shells) exhibit logarithmic spiral growth, but at a variety of angles usually distinctly different from that of the golden spiral. This pattern allows the organism to grow without changing shape. Approximate logarithmic spirals are common features in nature; golden spirals are one special case of these.

Famous quotes containing the word nature:

    I fairly confess that, acting as nature and simplicity dictated, no sooner did I see the once loved bosom of my Ferdinand free from those deformed demons which had crept in and filled up the vacant space, than beholding my natural home once more the seat of innocence and truth, my heart joyfully danced into its delightful abode.
    Sarah Fielding (1710–1768)
