What is Pixel

Handbook of Research on Computational Arts and Creative Informatics
Usually this word is used in the technical sense (and probably one you are well familiar with). But the general concept is often a hazy one. The term being popularly bandied about with careless excitement, refers digital-ity. It is the smallest indivisible element in a collection of like elements that comprise an entity. “All in all it’s just another brick in the wall.” You could say the places on a checkerboard are pixels. But they needn’t even be square. City blocks may be considered pixels. But they needn’t be configured in any orderly fashion. Cells in a cluster of tissue could be pixels. The audio equivalent of resolution is called the sample rate. Usually to call something a pixel, there needs to be an encompassing (explicit or implied) system. A colored dot of ink is not necessarily a pixel, until you consider it part of a larger picture, say in a newspaper.

Abstract
Culture is a byproduct of our brains. Moreover, we’ll look at ways culture also employs ritual (from shamanistic practices to grocery shopping) to shape neural paths, and thus shape our brains. Music has a definite (well researched) role in this feedback loop. The ear learns how to discern music from noise in the very immediate context of the environment. This serves more than entertainment purposes however. At a glance, we often can discern visual noise from images, nonsense from words. The dynamics are hardly unique to audial compositions. There are many kinds of compositional rules that apply to all of the senses and well beyond. The brain develops these rule sets specific to the needs of the culture and in order to maintain it. These rules, rarely articulated, are stored in the form of icons, a somewhat abstracted, context-less abbreviation open to wide interpretation. It may seem somewhat amazing we can come up with compatible rules, by reading these icons from our unique personal perspectives. And often we don’t, as we each have differing tastes and opinions. However, “drawing from the same well” defines abstract groupings, to which we choose to subscribe. We both subscribe to and influence which rule-sets we use to filter our perceptions and conclusions. But the way we (often unconsciously) choose is far more elusive and subtle.
