About the cover image, courtesy of Bahman Kalantari: Poly-
nomiography is the art and science of visualization in approxima-
tion of the zeros of polynomial equations using iteration functions.
Although its theoretical foundation can be traced to the well-
known Fundamental Theorem of Algebra, polynomiography offers
a new and exciting view into the world of polynomials as well
as the mysteries of this beautiful theorem itself. Not only is
polynomiography interesting and useful from the scientific and
educational points of view, but it turns the ancient root-finding
problem into a serious medium for creating artwork of great
variety and diversity through bination of human creativity
puter power. Each polynomial gives rise to an infinite
number of 2D images, each called a polynomiograph. Each natural
number can be identified as a polynomial. Hence, for each poly-
nomial and each natural number there is an infinite number of
polynomiographs waiting to be discovered. The particular image
on the cover is based on a polynomiograph produc
