Artists and scientists have much to offer each other in perceiving and describing the world, as well as creatively addressing its many challenges. To enable a meaningful exchange, the data, theories, and mathematics of scientists must find common ground with the images, sounds, and forms of artists. A common language based on spatial and temporal patterns is a potential vehicle because patterns are more fundamental and recognizable than are numbers, words, or abstract symbols. Pattern languages developed for architecture, software design, music, and similar disciplines can be modified to enhance the communication between artists and scientists. An essential collection of patterns, their supporting components, and some basic rules for structure constitute a first step toward building a pattern language that will be continually amended by users. There is substantial commonality in the underlying spatial and temporal patterns of the arts and sciences that can be revealed and utilized in developing such a language.
