2.2 Papers presented at recent meetings

* At the Conference in Honor of the 65th Birthday of Ubiratan D'Ambrosio (the 'father of ethnomathematics'), realized on January 6, 1998 in Baltimore (USA), two talks were related to the history of mathematics in Africa. Paulus Gerdes spoke about the historical development of ethnomathematical research in Mozambique and D'Ambrosio's influence. Nkechi Agwu (City University of New York) presented the paper "Mathematical teaching techniques inherent in Nigerian cultures".

* At the 76th Annual Meeting of the National Council of Teachers of Mathematics (2-4 April 1998, Washington DC, USA), various papers were presented which are related to mathematics in or from Africa:

Ron Eglash & Gloria Gilmer: African hairstyle designs;

Arthur Powell: Out-of-school application of ethnomathematics: the game of oware;

Daniel Ness: Ethnomathematics and Asante kete drumming;

Beatrice Lumpkin: Some mathematical gems from Egypt;

John Sims: Designs from the Kuba (Congo) and the teaching of mathematics to arts students;

Paulus Gerdes: Exploring geometrical ideas from Southern Africa;

Nelson Sanz: Problem solving and 'aha' calculation experiences with the Rhind mathematical papyrus;

Anthony Stevens & Janet Sharp: Learning about fractions and ratios by using African rhythms played on drums.



* Franz Gnaedinger (Zurich, Switzerland) is concluding a book entitled "Geometrie und Mathematik im alten Ägypten" (Geometry and Mathematics in ancient Egypt).

* Milo Gardner (Sacramento, USA) is analysing fractions in Ancient Egypt and prepared several manuscripts on "'false position' arithmetic that 'picked a number' to solve Egyptian fraction problems".



This section is reserved for questions that readers would like to have answered; these are the 'queries'. The answers will be the 'notes'. If you have questions or answers about sources, dates, names, titles, facts, or other such matters related to the history of mathematics in Africa, frame them in clear and concise language and send them to the editors. If you are answering a question, make clear reference to that question. All readers may send both questions and answers. Each will be published with the name of the sender.

* Mathematical manuscripts from Mali?

Mike Morelli (University of Wisconsin-Stout) has the following query "A while back, the Chronicle of Higher Education printed an article which stated that Dr. Henry Louis Gates, while in Mali, discovered 4000 books from a 14th century university library (Timbuktu?). I have been trying to get more information about this important discovery. What do you know about this? In what language are the books written? Were any of them math books? "



5.1 On the History of Mathematics in Africa

#248 Bashakova, I.: Diophantus and Diophantine Equations, Mathematical Association of America, Washington, 1997, 104 pp.

Presents the works of Diophantus of Alexandria, focusing on Diophantus' general methods of obtaining rational solutions of indeterminate equations of the second and third order. The second part of the book considers the evolution of the theory of Diophantine equations from the Renaissance to the middle of the 20th century.


#249 Kielland, Else Christie: Geometry in Egyptian Art, Alec Tiranti, London, 1955, 214 pp.
Presents a brief survey of Egyptian geometry based on the papyri that have been found, followed by the interpretations which scholars placed on the geometric marks found on the Egyptian works of art. Finally, Lange's law of frontality is discussed, with its revision by Schäfer.

#250 Lumpkin, Beatrice: From Egypt to Benjamin Banneker: African origins of false position solutions, in: Ronald Calinger (ed.), Vita Mathematica, Historical Research and Integration with Teaching, MAA Notes (MAA = Mathematical Association of America), 1996, Vol. 40, 279-289
Describes the use of the rule of false positions in ancient Egypt, in the work of later Alexandrian mathematicians, like Diophantus (c. 250), and of Abu Kamil (born 850), the influence on mathematicians in Europe and later on Benjamin Banneker (1731-1806), one of the first African American who dedicated himself to mathematics (cf. # 32, 82).

#251 Robins, Gay: Proposition and style in Ancient Egyptian Art, University of Texas Press, Austin, 1994, 279 pp.
"It has long been known that much Egyptian art executed in two dimensions as painting or relief was conceived and carried out on a squared grid, which helped to determine the proportions of the human figure. Although there have been several previous studies of the Egyptian grid, these have been almost entirely limited to single standing or seated male figures... In this book I have attempted to base my own ideas ... primarily on observations carried out on the actual monuments. I have considered female figures as well as male, other postures besides standing and sitting... I show that the squared grid had an important influence on the composition of scenes as a whole and in helping to determine the characteristic style of a particular period. I consider the effects of the major change in the grid that occurred in the twenty-fifth dynasty and persisted thereafter, and elaborate my discovery of the grid system adopted during the Amarna period." (Preface, p. vii)


5.2 Publications on the History of Mathematics, Ethnomathematics and Mathematics Education

#252 Ascher, Marcia: Malagasy Sikidy: A Case in Ethnomathematics, in: Historia Mathematica, New York, 1997, Vol. 24, 376-395
"Sikidy is a system of divination that plays a significant role in the lives of the people of Madagascar. Here we focus on the mathematical ideas which it embodies. Formal algebraic algorithms are applied to initial random data, and knowledge of the internal logic of the resulting array enables the diviner to check for and detect errors. Sikidy and the mathematical ideas within it are placed in their cultural and historical contexts".

#253 Doumbia, Salimata: Maths et Cultures: Pythagore en Afrique, in: Bulletin Harmonisation des Programmes de mathématiques des pays francophones d'Afrique et de l'Océan Indien, Abidjan, 1997, Vol. 3, 6-11
Gives examples of Pythagorical figurative numbers in West Africa and presents some ideas of Paulus Gerdes' book "African Pythagoras" on African crafts and the Pythagorean theorem (cf. # 108, 182).

#254 Eglash, Ron: Scaling hexagons in a Bassari initiation mask, in: Mathematics Teacher, Reston VA, 1995, Vol. 88, No. 7, pp. 618, 620
Short note that analyses the presence of a scaling series of hexagons in a mask from the Bassari (eastern Senegal) and compares it with the use of the number six in other contexts (time reckoning, string tallies, divination).

#255 Eglash, Ron: Bamana Sand Divination &#151 Recursion in Ethnomathematics, in: American Anthropologist, Arlington VA, 1997, Vol. 99, No. 1, 112-122
Reflecting on his fieldwork realized among Bamana (or Bambara) diviners, the author compares their use of recursion, where the iterative function is addition modulo 2, with Cantor's recursion (cantor set), and hypotheses that an African concept of self-generated fecundity is the shared origin of both the Bamana divination and transfinite set theory.

#256 Eglash, Ron; Christian Sina Diatta and Nfally Badiane: Fractal structure in Jola material culture, in: Ekistics, Athens, 1994, Vol. 368, 367-371
Discusses self-similarity in altar, house, and village structures among the Jola in the Lower Casamance region in southern Senegal.

"Benjamin Banneker (1731-1806) is well known for his accomplishments in early American applied science, as well as for his seminal role in African-American science history. Historical and linguistic evidence suggests that his grandfather was of Wolof origin, and that his father was from the area between what is now Ghana and Nigeria. This cultural heritage may have emerged in some of his mathematical thinking" (p.307). (cf. # 32, 82)

#258 Eglash, Ron: Geometric algorithms in Mangbetu design, in: Mathematics Teacher, Reston, 1998, Vol.91, No.5, 376-381
Analyzes an ivory hat pin from the Mangbetu (northeastern Zaire / Congo) and the geometric algorithm involved in its production. The top of the pin is composed of four scaled, similar heads (forming isosceles right triangles in photographic projection).

#259 Gerdes, Paulus: On culture and mathematics teacher education, in: Journal of Mathematics Teacher Education, Dordrecht, 1998, Vol. 1, No. 1, 33-53

#260 Huylebrouck, D.: The bone that began the space odyssey, in: The Mathematical Intelligencer, New York, 1996, Vol. 18, No. 4, 56-60
Describes the Ishango bone (Congo / Zaire) as a Mesolithic mathematical artifact, some interpretations of the notches, and uses. Shallit remarks in a letter to the editor (Vol. 19, No. 3, p. 7) that papers by A.S.Brooks present a date of 20,000 years ago (not 11,000 years ago as stated by Huylebrouck) for the bone (cf. #20, 99, 162)
