Jay Kappraff was an American professor of mathematics at the New Jersey Institute of Technology and author. [2]
Kappraff was trained in engineering, physical sciences and mathematics, earning a B.Ch.E. in chemical engineering at New York Polytechnic in 1958. He went on to be awarded a PhD in applied mathematics in 1974 from the Courant Institute of Mathematical Science, New York University and a M.S. in chemical engineering in 1960 from Iowa State University. He began work for DuPont DeNemours as a chemical engineer from 1961 to 1962 going on to teach mathematics for a brief period before obtaining a position at NASA as an aerospace engineer from 1962 until 1965. He went on to be an instructor of mathematics at the Cooper Union College, New York City from 1968 until 1974. Following this, he joined the New Jersey Institute of Technology, where he currently works. He was a consultant for the Department of Energy in 1976. In 1978 he developed a course in the mathematics of design for computer scientists, mathematicians and architects. [3] In bringing together such an interdisciplinary range of subjects, he began to study what he termed a common language of design and geometry. [4] He has been a lecturer on the relationship between art and science and published a large number or articles on subjects ranging from plasma physics, solar heating, aerospace engineering and fractals. He has also published a number of books on these and related subjects and compiled a series of video lectures on the science of design.
In 1991 his book Connections won a prize for the best book in chemistry, physics, mathematics, astronomy and reference from the Association of American Publishers. [2]
At the NJIT, Kapraff has organized various forums and tuition programs on subjects from Nuclear war and ancient geometry to experimental mathematics. he is a member of the faculty council and chairman of the NJIT Technology and Society Forum committee. He is a member of the Mathematics Association of America and on the editorial board of a new interdisciplinary journal, the International Journal of Biological Systems. He was also guest editor of the journal FORMA for a special issue on the golden mean in 2005.
In mathematics, a fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. Many fractals appear similar at various scales, as illustrated in successive magnifications of the Mandelbrot set. This exhibition of similar patterns at increasingly smaller scales is called self-similarity, also known as expanding symmetry or unfolding symmetry; if this replication is exactly the same at every scale, as in the Menger sponge, the shape is called affine self-similar. Fractal geometry lies within the mathematical branch of measure theory.
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. Expressed algebraically, for quantities and with , is in a golden ratio to if
A pattern is a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner. A geometric pattern is a kind of pattern formed of geometric shapes and typically repeated like a wallpaper design.
William Kingdon Clifford was an English mathematician and philosopher. Building on the work of Hermann Grassmann, he introduced what is now termed geometric algebra, a special case of the Clifford algebra named in his honour. The operations of geometric algebra have the effect of mirroring, rotating, translating, and mapping the geometric objects that are being modelled to new positions. Clifford algebras in general and geometric algebra in particular have been of ever increasing importance to mathematical physics, geometry, and computing. Clifford was the first to suggest that gravitation might be a manifestation of an underlying geometry. In his philosophical writings he coined the expression mind-stuff.
In botany, phyllotaxis or phyllotaxy is the arrangement of leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature.
Jay Hambidge (1867–1924) was an American artist who formulated the theory of "dynamic symmetry", a system defining compositional rules, which was adopted by several notable American and Canadian artists in the early 20th century.
Geometry is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a geometer. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts.
A dynamic rectangle is a right-angled, four-sided figure with dynamic symmetry which, in this case, means that aspect ratio is a distinguished value in dynamic symmetry, a proportioning system and natural design methodology described in Jay Hambidge's books. These dynamic rectangles begin with a square, which is extended to form the desired figure, which can be the golden rectangle, the 2:3 rectangle, the double square (1:2), or a root rectangle.
Islamic geometric patterns are one of the major forms of Islamic ornament, which tends to avoid using figurative images, as it is forbidden to create a representation of an important Islamic figure according to many holy scriptures.
Mathematics and art are related in a variety of ways. Mathematics has itself been described as an art motivated by beauty. Mathematics can be discerned in arts such as music, dance, painting, architecture, sculpture, and textiles. This article focuses, however, on mathematics in the visual arts.
Denis Louis Blackmore was an American mathematician and a full professor of the Department of Mathematical Sciences at New Jersey Institute of Technology. He was also one of the founding members of the Center for Applied Mathematics and Statistics at NJIT. Dr. Blackmore was mainly known for his many contributions in the fields of dynamical systems and differential topology. In addition to this, he had many contributions in other fields of applied mathematics, physics, biology, and engineering.
Anne Macaulay was a Scottish musicologist, author and lecturer.

Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. Early Greek philosophers studied pattern, with Plato, Pythagoras and Empedocles attempting to explain order in nature. The modern understanding of visible patterns developed gradually over time.
Vera Martha Winitzky de Spinadel was an Argentine mathematician. She was the first woman to gain a PhD in mathematics at the University of Buenos Aires, Argentina, in 1958. Between 2010 and 2017, she was full Emeritus Professor in the Faculty of Architecture, Design and Urban Planning of the University of Buenos Aires.

In the mathematics of circle packing, a Doyle spiral is a pattern of non-crossing circles in the plane in which each circle is surrounded by a ring of six tangent circles. These patterns contain spiral arms formed by circles linked through opposite points of tangency, with their centers on logarithmic spirals of three different shapes.
