<h2 class="featurette-heading">Galaxies <span class="text-muted"></span></h2>
<p class="lead">Not surprisingly, spiral galaxies also follow the familiar Fibonacci pattern. The
Milky Way has several spiral arms, each of them a logarithmic spiral of about 12 degrees. As an
interesting aside, spiral galaxies appear to defy Newtonian physics. As early as 1925,
astronomers realized that, since the angular speed of rotation of the galactic disk varies with
distance from the center, the radial arms should become curved as galaxies rotate. Subsequently,
after a few rotations, spiral arms should start to wind around a galaxy. But they don't — hence
the so-called winding problem. The stars on the outside, it would seem, move at a velocity
higher than expected — a unique trait of the cosmos that helps preserve its shape.</p>

<h2 class="featurette-heading">Shells <span class="text-muted"></span></h2>
<p class="lead">The unique properties of the Golden Rectangle provides another example. This shape,
a rectangle in which the ratio of the sides a/b is equal to the golden mean (phi), can result in
a nesting process that can be repeated into infinity — and which takes on the form of a spiral.
It's call the logarithmic spiral, and it abounds in nature.</p>

<h2 class="featurette-heading">Flower Petals <span class="text-muted"></span></h2>
<p class="lead">The number of petals in a flower consistently follows the Fibonacci sequence. Famous
examples include the lily, which has three petals, buttercups, which have five (pictured at
left), the chicory's 21, the daisy's 34, and so on. Phi appears in petals on account of the
ideal packing arrangement as selected by Darwinian processes; each petal is placed at 0.618034
per turn (out of a 360° circle) allowing for the best possible exposure to sunlight and other
factors.</p>

<h2 class="featurette-heading">Faces <span class="text-muted"></span></h2>
<p class="lead">Faces, both human and nonhuman, abound with examples of the Golden Ratio. The mouth
and nose are each positioned at golden sections of the distance between the eyes and the bottom
of the chin. Similar proportions can been seen from the side, and even the eye and ear itself
(which follows along a spiral).</p>
