Influencing Cybernetics

The use of African material culture as a form of analog representation is particularly vivid in cases of recursive information flow. In African architecture, recursive scaling – that is fractal geometry – can be seen in a variety of forms. In North Africa it is associated with the feedback of he “arabesque” artistic form, particularly in the branches of branches forming city streets. In Central Africa it can be seen in additive rectangular wall formations, and in West Africa we we circular swirls of circular houses and granaries. This is not limited to a visual argument; the fractal structure of African settlement patterns has been confirmed by computational analysis of digitized photos in Eglash and Broadwell (1989).
Recursive scaling in Egyptian temples can be viewed as a formalized version of the fractal architecture found elsewhere in Africa, and is most significant in it’s use of the Fibonacci sequence. The sequence is named for Leonardo Fibonacci (ca. 1175-1250), who is also associated with an unusual example of recursive architecture in Europe. The Fibonacci sequence was one of the first mathematical models for biological growth patterns, and inspired Alan Turing and other important figures in the history of computational morphogenesis. Since Fibonacci was sent to North Africa as a boy and devoted his years there to mathematics education (Gies and Gies 1969), it is possible that seminal example of recursive scaling is of African origin...[continue reading]
