Cats, Spirals, patterns
The cat species Felis catus is also known as the domestic cat or housecat to distinguish it from other felines and felids. Cats are a small furry domesticated carnivorous mammal valued by humans for their companionship and its ability to hunt vermin and household pests. Associated with humans for over 95 thousand years, today cats are the most popular pet in the world and are found almost everywhere on earth. Cats come from the Kingdom of Animalia, the Phylum of Chordata, and the Mammalia Class. They are of the Order Carnivora, the Felidae Family and the Genus Felis. Similar in anatomy to the other felids, cats have strong, flexible bodies, quick reflexes, sharp retractable claws, and sharp teeth. They are nocturnal predators, with acute hearing and ability to see in near darkness. Cats hear sounds too faint for human ears and can also hear sounds higher in frequency than humans can perceive. A social species, cats use body language and their voice to communicate. This includes purring
A spiral is a type of curve that has several definitions. The two primary definitions of a spiral provided by the American Heritage Dictionary include a curve on a plane that winds around a fixed center point at a continuously increasing or decreasing distance from the point, or a three-dimensional curve that turns around an axis at a varying distance while moving parallel to the axis. In mathematics, a spiral is a curve which emanates from a central point, getting progressively farther away as it revolves around the point. The spiral is often seen in nature, in art, and in science. The spiral plays a specific role in symbolism, and appears in megalithic art, notably in the Newgrange tomb or in many Galician petroglyphs such as the one in Mogor. See, for example, the triple spiral. Spirals are also a symbol of hypnosis, which comes from the trite showing of people and cartoon characters being hypnotized by staring into a spinning spiral.
The word pattern comes from the French patron, which is a type of theme of recurring events or objects, sometimes referred to as elements of a set of objects. Patterns are elements that repeat in a predictable manner. The most basic patterns are called Tessellations. These types of patterns are based on repetition and periodicity. A single template, tile, or cell, is combined with duplicates without change or modification. Visual patterns are very common and can be simple decorative patterns (stripes, zigzags, and polka dots). Others can be more complicated, however, they may be found anywhere in nature and in art. In art, one recurring pattern in a single piece of art can be termed a motif. In Math, any sequence of numbers that may be modeled by a mathematical function is considered a pattern. Patterns also are used in computer science where complex mathematical models may be designed to create more complex patterns. Patterns appear in geology and other aspects of nature.
