Download E-books Lunda Geometry: Mirror Curves, Designs, Knots, Polyominoes, Patterns, Symmetries PDF

By Paulus Gerdes

The e-book "Lunda Geometry" explains how the mathematical options of replicate curves and Lunda-designs have been came across within the context of the authors study of 'sona, illustrations typically made within the sand through Cokwe storytellers from jap Angola (a area known as Lunda) and neighboring areas of Congo and Zambia. Examples of replicate curves from numerous cultures are awarded. Lunda-designs are aesthetically appealing and show attention-grabbing symmetry houses. Examples of Lunda-patterns and Lunda-polyominoes are awarded. a few generalizations of the idea that of Lunda-design are mentioned, like hexagonal Lunda-designs, Lunda-k-designs, Lunda-fractals, and round Lunda-designs. Lunda-designs of Celtic knot designs are constructed.
Several chapters have been released in journals like 'Computers & pix (Oxford), 'Visual arithmetic (Belgrade), and 'Mathematics at school (UK). (198 pp.)
