![]() ![]() An even smaller proportion-perhaps 1%-are born innately ambidexterous. Most people who can use both hands with facility, called ambidextrous, are self-trained (and often culturally trained).īeing left-handed has never been popular, and left-handed people learn to use both hands. Why would nature choose the right hand over the left repeatedly for the human species? Language-the most important human attribute because it allows us to communicate across generations and cultures, thus increasing the likelihood of survival-resides in the left hemisphere of the brain, which controls the right side of our body. Whether flying, swimming, crawling or walking, animals must have appendages of equal proportion on both sides if they are to have reliable and balanced movement through space.Ī little over 90% of people are born right-handed, regardless of culture, writing preference and racial or linguistic qualities. the same on both sides when split down the middle). Most bodies of animals are bilateral along a mirrored line (i.e. After fertilization, an egg splits in half and begins the process of billions of subsequent divisions, resulting in the mirrored symmetry of a bilateral body. The beginning of life itself exhibits this symmetry. This symmetry involves coordinated two-sided movement, representing a higher order of symmetry. More complex than translation symmetry is reflection symmetry, a fundamental trait of all moving creatures. Is there a reason why this symmetry was chosen by these particular organizations? Bear in mind, too, that these kinds of design choices are often made at an unconscious level by the designer. How many examples of translation symmetry can you find in identity design? It’s not as common as the other symmetries explored here because it is perhaps not quite as engaging. Translation symmetry is a visually subtle way to convey this message. Individually, we may stand alone, but as a group, we are essentially the same. These public messages emphasize equality and unity. Not as linear as PBS’, this one gradually morphs from people into an eagle, transforming the US population into the country’s primary symbol. The US Department of Health and Human Services also uses a form of translation symmetry. The repeated visual is an effective way for the PBS to represent its balanced programming and to show its equal consideration of the ethnic, age and gender diversity in its audience. The repeating human face in its logo, alternating progressively from black to white and black again, visually conveys this purpose very well. PBS focuses on multi-generational and multi-cultural educational programming, delivered in an objective style. To take an example from graphic design, translation symmetry has been used to good effect by the PBS network. ![]() For example, a row of corn kernels contains genetic information for successive crops, and a pure-bred animal contains specially cultivated traits that will be passed down its line. Translation symmetry is also found in the basic notion of reproduction, by which a “lineage” is created by one generation inheriting the previous generation’s characteristics. In architecture, it is used for three-dimensional support by distributing weight evenly across load-bearing beams and columns. It is commonly used as a border to hold more complex patterns “in line” on a two-dimensional space. ![]() In its simplest form, symmetry is a repeating pattern of identical elements that are equally spaced out along a line. Effective Logo Design, Part 3: How Geometry Influences Logo Design.Applying Divine Proportion To Your Web Designs.Please consider reading our related articles: As a simple aesthetic, these opposites that work together can add visual appeal. Each of them has specific and practical expressions in nature, and each can be used to communicate intuitive principles when appropriately and subtly integrated in a design. There are several types of symmetry, but the most basic are translation, reflection and rotational. Consequently, humans have borrowed this principle for its most iconic creations and symbols. In nature, symmetry exists with such precision and beauty that we can’t help but attribute it to intelligence–such equal proportions and organization would seem to be created only on purpose. As a fundamental design principle, it permeates everything: from man-made architecture to natural crystalline formations. ![]() Symmetry is the ordering principle in nature that represents the center of balance between two or more opposing sides. ![]()
