The book “Lunda Geometry” explains how the mathematical concepts of mirror curves and Lunda-designs were discovered in the context of the author’s research of ‘sona’,... More > illustrations traditionally made in the sand by Cokwe storytellers from eastern Angola (a region called Lunda) and neighboring regions of Congo and Zambia. Examples of mirror curves from several cultures are presented. Lunda-designs are aesthetically attractive and display interesting symmetry properties. Examples of Lunda-patterns and Lunda-polyominoes are presented. Some generalizations of the concept of Lunda-design are discussed, like hexagonal Lunda-designs, Lunda-k-designs, Lunda-fractals, and circular Lunda-designs. Lunda-designs of Celtic knot designs are constructed. Several chapters were published in journals like ‘Computers & Graphics’ (Oxford), ‘Visual Mathematics’ (Belgrade), and ‘Mathematics in School’ (UK). (198 pp.)< Less
Sona Geometry from Angola: Mathematics of an African Tradition (color edition) By Paulus Gerdes
Paperback: $45.95
Prints in 3-5 business days
The ‘sona’ tradition belongs to the culture of the Cokwe and related peoples in Eastern Angola and neighboring areas of Northwest Zambia and the Congo. Observers have described... More > ‘sona’ as sand graphs, sand drawings, drawings in the sand, writing in the sand, pictographs and ideograms, and as a system of communication. The ‘sona’ tradition is multifaceted. It comprises aspects that are philosophical, educational, artistic, ideographic, and recreational. The book shows that mathematical considerations were involved and developed as the Cokwe invented ‘sona’ and built up a reservoir of symbolic-graphic expressions. The book presents an analysis and reconstruction of mathematical elements in the sona tradition. The first English language edition in color contains an updated bibliography and an appendix with a brief introduction to new mathematical ideas that came out of the study of ‘sona.’ Translation and Preface: Artur B. Powell, Rutgers University, Newark, USA; 248 pp., over 500 illustrations in color.< Less
