"This book, on the mathematics of natural and artful form, is a lively new entrant to the small shelf of those fine works."
Scientific American
"If I had only one book in my library to which I refer for mathematics questions in art and architecture, this would be the one."
Nexus Network Journal
"A worthy volume rediscovers the golden mean for readers in the postgeometry generation."

"... Kappraff's book is nothing less than the first textbook of design science."
Bulletin of the Buckminster Fuller Institute
"This is no less than an early and strong move toward implementing Buckminster Fuller's call for a Comprehensive Anticipatory Design Science. Even a less-than-rigorous reading will convince you that something important is being presented here."
Whole Earth Review
"For the visually oriented person with a hunger to understand pattern, Connections can be a bridge to a new world."
American Journal of Physics
"A spectacular presentation of design science -- 'the grammar of space' -- that explores with rich details instances of similarity, proportion, tilings, graphs, lattices, polyhedra, isometries, and symmetry in art, architecture, engineering, and science. Punctuated with exercises and problems (thus making the monograph useful as a course or seminar text); illustrated with over 200 figures; supported by an extensive multi-disciplinary bibliography that is well-referenced to the text. A superb option for interdisciplinary seminars."
American Mathematical Monthly
The first edition of Connections was chosen by the National Association of Publishers (USA) as the best book in "Mathematics, Chemistry, and Astronomy -- Professional and Reference" in 1991. It has been a comprehensive reference in design science, bringing together in a single volume material from the areas of proportion in architecture and design, tilings and patterns, polyhedra, and symmetry. The book presents both theory and practice and has more than 750 illustrations. It is suitable for research in a variety of fields and as an aid to teaching a course in the mathematics of design. It has been influential in stimulating the burgeoning interest in the relationship between mathematics and design. In the second edition there are five new sections, supplementary, as well as a new preface describing the advances in design science since the publication of the first edition.
