Fractals in Nature and Mathematics
One way we see, model and construct/deconstruct the world is by the use of traditional (Euclidean) shapes of geometry, i.e. circles, squares, pyramids, spheres. For example, we can design and build a house (or deconstruct one) using such regular shapes. However, how would an irregular- or fragmented- shaped object, such as a mountain chain, coastline, tree, a snowflake, the Grand Canyon, a sprig of broccoli be modeled or constructed? If one looks closely at such objects, they might see that they can be broken apart into a shape that is a “reduced copy of the whole”. For example, the two-dimensional surface of mountain range can be modeled as a collection of triangles. Mathematically this is accomplished by taking a “seed” reflective of the whole, plugging it into an algorithm and continually iterating (repeating) the algorithm again and again. In this process, called recursion, the seed feedbacks on itself, further adding to and refining the resulting object.
The mathematical objects created by such iterative processes are called fractals,
a term coined by Benoît Mandelbrot in 1975. Fractals have their root in fractus, meaning broken or fractured. The dimensionality of a fractal is fractional, i.e. 1.39 or 1.67, and often between 1 and 2. Since the number of fractions is much greater than the number of whole numbers (0, 1, 2…) the number of fractals, and hence fractal dimensions and objects, dwarfs our habitual 2-D and 3-D views of the universe.
A well-known example of fractal mathematics used to model a a snowflake begins with an equilateral triangle (a triangle whose sides have the same length). The middle third of every side of the triangle is replaced with a pair of lines that form an equilateral “bump”. The result is called a Koch snowflake when iterated. A video of the process http://en.wikipedia.org/wiki/Fractal shows that only a few iterations will transform a triangle into a snowflake. I encourage you to watch the PBS Nova special (http://www.pbs.org/wgbh/nova/physics/hunting-hidden-dimension.html) about the history of fractal mathematics and to see how other objects are made.
To summarize, a fractal is a mathematical object that begins with a seed and grows, or as a friend of mine said, “as above, so below”. And, much like poetry and art, fractal mathematics is a geometry that finds order out of chaos.
Fractals in Art and Poetry
The recursive nature of fractal mathematics is often employed in media, animation, and digital art. Computer screensavers are one common example. Fractals are also found in “traditional” art. Computer analysis has shown fractal patterns appear in the paintings of Jackson Pollock. Why might Pollack’s paintings have fractal regions embedded in them?
Intentionally and unintentionally poets write fractal poems. A fractal poem is one that employs a seed phrase, uses symmetry and repetition of word-types and sounds, and considers dimensionality. Diana Der Hovanessian, with a nod to Edna St. Vincent Millay, beautifully describes the transition from Euclidean geometry to fractal geometry in her surprising poem Fractals (see http://aurorastyle.blogspot.com/2010/09/fractals-by-diana-der-hovanessian.html). Fractals is iteration on the traditions of mathematics and poetry!
Below are four other fractal poems that exhibit different aspects of fractals. Consider the following questions while you read the poems or say them aloud:
What is the seed, or seeds, of each poem?
What words or word-types add texture and dynamics to the poem and help move it? Consider the multiplicity of meanings that some of the words have;
How does the scale of the poem progress? Does it move outward, inward, or in another direction? What does this reveal to the reader about the author’s life or scene?
How does the author “escape” the fractal iteration and end the poem? What might this hint about the things that lie beyond the poem?
Escaping the Mandelbrot Set
Robin Chapman
She says
The coffee is fine
Though it could have been stronger
And cream would be nice.
She says
The weather today
Is, yes, fine, though cold
For summer and more rain likely tonight.
She says
The summer’s going well,
Of course awfully fast and won’t last
Long enough to get done what she’d planned.
She says
The marriage was ten good years
And then ten bad, and she’s learned
A lot since, though of course it’s lonely.
She says
Buying a new cappuccino maker,
Espresso roast, and best jam for her bread
Is frivolous, but we only have one life.

Migratory
Daniel Stewart
If no one; if nothing, if not me; if burning; if wing; if organ
(failing); eyes: mouths. Vise.
If trap knows teeth. If nerve knows cruel. If heart knows blood. If
water tongues fire.
Hiss of water. If hand kneads fire. If instinct (:desire). If seasonal,
flower. If I the liar.
I the liar. If God’s lips glazed with pollen’s praise.
If flight is ache is palm frond’s wince in salt and wind.
If whale, fin and foam, wave and spray.
If Man-O-War, promise sting.
If Monarch, splinter chrysalis into rein.

Fractal
Arthur Sze
Stopped at an intersection,
ruminating on how, in
a game of go, to consider all
the possible moves until
the end would take a computer
longer than the expected
lifetime of the universe,
you flit from piccolo
to stovepipe in a letter,
to scrutinizing faces
while standing in line
at the post office, to weather
forecast – a snowflake
has an infinite number of possible shapes –
consider, only last weekend,
a wasp threaded along a
screen door in south light,
mark the impulse to – not
see this, do that – water
leafing pear trees along
a curved driveway, relax
the intricate openwork mesh
of spring, recall lifting
a packet of flax seed
off the counter, and, checking
for an expiration date,
note – red light, green light –
sow when danger of
frost is past, then go, go.

Purification Fractal

Grand Canyon National Park
Booted, at the rim
step down forward
start reverse
step a minute, a day
sixty-thousand years
step, stepped, steeped
dry tawny Toroweap
my eyes weep
weeping, last night’s rain
pooled in sepia Esplanade
here is camp
tinaja, sandstone,
limestone, sandstone
salty sea bones
here is rattlesnake
here memory falls
form forming warping
worked Amerindian stone
working tool
clatter clattered
conglomerate rubble
sandstone, limestone
ocean silted
Red Wall limestone
rubbled, rubble
blistered, blistering
feet step, stepped,
layered, layers
faulted, avalanched
bloody pricks
of desert bricklebrush
proffered prickly pear
thunder thundered river
from sandstone wall
here is two-night camp
scorpion, scorpion-eating
pallid bat, hear pack rat
scurry, cottonwood rustle
silent great-horned owl,
hear morning camp-robber
raven flap flap
we hit the trail ahead
slick rain slickened
tumbled down
Cardenas ball-bearing
lava, Shinumo shale
narrow ledge
exposed exposure
above flowing
Tapeats ribbon
flowing into early,
early energy, pressured
heated folded
folded heated
folded river-severed
black, blackened, buried
two-billion-year old schist
gracing our handholds
released again
to movement
While it may seem these poems are no different than other “stream-of-consciousness” or abstract poems, there can be no doubt they affect the reader’s senses differently, such as haiku does. I, for one, get chills and tingles when I read and recite such poems. Or write one. Such results do not surprise me – the human circulatory system with its beating heart at the center, beginning and end is the quintessential fractal system found in Nature.
