The Symbol of Beauty
One of the more striking
observations to be made about nature is the strong propensity
towards symmetry and repetitive patterning. Symmetry is evident
in living and non-living structures. Throughout the ages, from
primitive tribal communities to modern electronic civilizations,
symbols have been used to describe the simple, complex, tangible
and intangible. These symbols display a wide range of materials
and techniques, yet they also carry a common denominator. This
common thread is the composition of symmetry which is influenced
by nature and the environment. It is a recurring visual
composition which has evoked passion in all human beings. But
what exactly is this passion and from where does this passion
come? In comparing and contrasting art objects throughout
history it becomes clear that symmetry is a basic concept for
creating images and that there are a wide range of objectives
associated with these images. Is their an innate link between
symmetry and the end goals of these art objects? Could
symmetrical composition be an intricate part of defining beauty?
Symmetry in Nature
Many species in nature are
symmetrical many more exhibit random or repeating patterns.
It is important to determine if the species or object is
symmetrical or merely contains a pattern.

Realizing
the symmetry of living organisms will help us to better
understand the anatomy of the organisms. Understanding the
symmetry of inorganic material such as crystals will better help
us to determine the qualities and uses of the substances.
Sandollars,
sea shells, flowers, faces, fish (even flounders)... the list
goes on and on. Each item offering a unique form immersed in
symmetry. In detail, there are always imperfections rendering an
object not perfectly in equilibrium but the overall form is
symmetrical. Symmetrical patterns in nature have influenced
artists and architects throughout history and have played an
important role in the shaping of our environment as well as the
creation of our culture and society.
The word ‘symmetry' is often used
in everyday language, and usually people of all ages (young and
old) can recognize symmetry when they see it.
Do you ever wonder why that happens?
Well, the reason for this is that symmetry can be found
everywhere and in everything around the world. There are several
different kinds of symmetry, but the one that appears in nature
most often is called bilateral symmetry.
Here are some examples of bilateral symmetry in nature:

If you take any of the pictures
above and divide them vertically in the middle, the left and the
right halves of the image will be mirror reflections of each
other.
The beauty of symmetry in nature inspired a famous poet William
Blake to write a poem about it:

Symmetry is also an innate
characteristic of human psychology. "As infants, humans have a
preference for looking at faces. Young infants also prefer
looking at complex patterns such as a bull's eye or a
checkerboard rather than simple ones"3. It is truly fascinating
when infants are learning to focus. Their pupils dilate and
narrow as they begin the process of vision. First in black and
white and later in color the visual world is a new experience
and being able to recognize providers and threats is a
challenge. The first images infants focus on are faces. These
faces provide the infant with a reference of survival. It is in
these symmetrical images that the newborn infant realizes a new
security. The infant can find peace and reassurance in
recognizing a parent. The human being is a complex organism
which itself is symmetrical. When we first encounter a newborn
our fears are centered around health. Is the baby OK? Does the
baby have two hands, two feet, five fingers on each hand and
foot? Health is immediately perceived through visual symmetry.
Once the newborn has passed this visual exam, it is beautiful,
it is perfect, and with this notion comes a complete feeling of
happiness. A joy that dispels all the fears of deformation and
proves them to be false.
Is there a link between symmetry and beauty?
Is symmetry the symbol of beauty?

HUMAN SYMMETRY
THE 'PROPORTIONS OF MAN' IS A
FAMOUS WORK OF ART BY LEONARDO DA VINCI
THAT SHOWS THE SYMMETRY OF THE HUMAN FORM.

A Snowflake

We don't have to examine nature very closely to see its beauty.
A bird, a forest or a galaxy has a form of beauty which is
typical of complex organised systems. A snowflake has another
element to its beauty which is also very common in nature but
which is often only evident on close inspection. We call it
symmetry.

The snowflake begins its life as a minute hexagonal crystal
forming in a cloud. During its passage from there to the ground,
it experiences a sequence of changes in temperature and humidity
which cause it to grow at varying rates. Its history is recorded
in the variations of thickness in its six petals as it grows.
This process ensures that each petal is virtually identical and
accounts for the snowflakes symmetry.

When a snowflake is rotated through an angle of 60 degrees about
its center, it returns to a position where it looks the same as
before. It is said to be invariant under such a transformation
and it is invariance which characterizes symmetry. The shape of
the snowflake is also invariant if it is rotated through 120
degrees. It is invariant again if it is turned over. By
combining rotations and turning over it is possible to find 12
different transformations (including the identity transformation
which does nothing). We say that the order of the snowflakes
symmetry is 12.
