      ( views) Vector Analysis by J. Willard Gibbs - Yale University Press, A text-book for the use of students of mathematics and physics, taken from the course of lectures on Vector Analysis delivered by J. Willard Gibbs. Numerous illustrative examples have been drawn from geometry, mechanics, and physics. ( views).   They were the elite in the Chokwe society. The slave trade caused the sona drawings to disappear. What we know of sona drawing comes mainly from drawings collected by an ethnographer in the s and s. The sona used geometric algorithms to construct their drawings. They used a type of coordinate system with a grid (net) of points.

"This volume provides readers with a glimpse into Paulus Gerdes's seminal work on the mathematics of an African tradition-sona geometry, a drawing and narrative tradition from Angola with embedded mathematical ideas.

The work represented in this book contributes significantly to efforts by other African mathematicians and mathematics educators Author: Paulus Gerdes. Sona (sing. Lusona) drawing is an ideographic tradition known across eastern Angola, northwestern Zambia and adjacent areas of the Democratic Republic of the Congo, and is mainly practiced by the Chokwe and Luchazi people.

These ideographs function as mnemonic devices to record proverbs, fables, games, riddles and animals, and to transmit knowledge.

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’.

Sona is an international auxiliary language created by Kenneth Searight and described in a book he published in The word Sona in the language itself means "auxiliary neutral thing", but the name was also chosen to echo "sonority" or "sound".

[citation needed]Searight created Sona as a response to the Eurocentricity of other artificial auxiliary languages of his time, such as Esperanto Created by: Kenneth Searight. In Sona Geometry, Gerdes demonstrates the inextricable links between sona and various branches of mathematics.

Through the knowledge of sona, passed from generation to generation via beautiful, often symmetric, designs made in the sand, Gerdes uncovers mathematical ideas and presents examples of how they may be used in.
