Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. [ 1] Early Greek philosophers studied pattern, with Plato ...
Trypophobia is an aversion to the sight of repetitive patterns or clusters of small holes or bumps. [ 3][ 4][ 5] It is not officially recognized as a mental disorder, but may be diagnosed as a specific phobia if excessive fear and distress occur. [ 1][ 4] Most affected people experience mainly disgust when they see trypophobic imagery. [ 4]
A hair whorl is a patch of hair growing in a circular direction around a visible center point. In a fingerprint, a whorl is each ridge arranged circularly around a central point on the finger. In histopathologic architecture, a whorled pattern consists of multiple concentric objects, or a spiral-shaped pattern. Bone tissue is shown.
The neural network scanned vegetation in those images and identified repeating circular patterns that resembled patterns of known fairy circles, evaluating the circles’ sizes and shapes as well ...
Circular dichroism (CD) is the differential absorption of left- and right-handed circularly polarized light. Circular dichroism is the basis of a form of spectroscopy that can be used to determine the optical isomerism and secondary structure of molecules. In general, this phenomenon will be exhibited in absorption bands of any optically active ...
Concentric objects. An archery target, featuring evenly spaced concentric circles that surround a "bullseye". Kepler's cosmological model formed by concentric spheres and regular polyhedra. In geometry, two or more objects are said to be concentric when they share the same center. Any pair of (possibly unalike) objects with well-defined centers ...
Butterflies. Butterfly/ butterflies. A common motif used in Chinese embroidery and in Chinaware. [ 12] The butterfly is a symbol of joy and summer. [ 12] It also implies long life, beauty and elegance. [ 6] Pair of butterflies. Pair of butterflies embroidered on clothing strengthens the energy of love.
Pennsylvania Dutch hex signs are a familiar type of motif in the eastern portions of the United States. Their circular and symmetric design, and their use of brightly colored patterns from nature, such as stars, compass roses, doves, hearts, tulips, leaves, and feathers have made them quite popular.
