2.4 Course on "Arab Mathematics between the East, the Maghreb and Spain"
At the invitation of the University of Mons-Hainaut and the Free University of Belgium, Ahmed Djebbar (Algeria) delivered in February and March 2003 a series of 8 lectures on the themes "Arab mathematics between the east, the Maghreb and Spain."
The 8 dealt with the following topics:
Thirty teachers and researchers took part in the course. A book will be published containing the text of the lecture series.
2.5 History of Science Activities in Cairo
During the month of April 2003 the University of Cairo and other Egyptian cultural organisms organised, in collaboration with the French Centre for Cultural Co-operation (CFCC), several activities around the theme "when science speaks Arab." Some of these activities envisaged a public of school going youth: publication of booklets on Arab art and sciences, and organisation of games. Other activities concerned the general public: an exhibition, an international colloquium and a series of lectures.
The exhibition took place at the Cairo Museum for Islamic Art. It was dedicated to different scientific activities in Egypt and other islamic countries in the period from the 9th to the 15th century and displayed manuscripts and ancient scientific instruments.
The colloquium took place at the University of Cairo (April 15-16). It was organised in collaboration with the University of Science and Technology of Lille (represented by Ahmed Djebbar and Bernard Maitte). The following papers were presented:
A series of lectures on the history of mathematics and physics was given in the buildings of the Supreme Council of Culture before and after the colloquium:
In parallel to these activities, Ahmed Djebbar organised a working session with mathematics lecturers of Cairo University interested in the history of mathematics. During this meeting, in which also Nefertiti Megahed (member of AMUCHMA) took part, a fruitfull exchange of ideas took place with the aim to determine the possibilities and modalities of the development of activities in the field of the history of mathematics at Cairo University.
During the opening session of the colloquium, a convention of co-operation was signed by Bernard Maitte, Director of the Centre for the History of Science of the University of Science and Technology of Lille and by Refaat Hilal, Director of the Heritage Centre of Cairo University.

3. CURRENT RESEARCH INTERESTS
3.1 Note on research inspired by the historical reconstruction of mathematical ideas in the 'sona' geometric tradition of Southern-Central Africa
Wolfgang Jaritz (1983) of the University of Graz (Austria) may have been the first to do mathematical research inspired by the 'sona' tradition of the Cokwe and related peoples of eastern Angola and neighbouring regions of Zambia and Congo. Informed by the anthropological studies of Gerhard Kubik, he studied the algorithm for drawing a particular class of 'sona' and compared it to the paths of a ball at a billiard table. Marcia Ascher (1988, 1990) of the Ithaca College (USA) analysed several 'sona' as graphs. The book by Gerdes (1993, 1994, 1995, 1997a) contributed to the historical reconstruction and analysis of mathematical ideas inherent in the 'sona' tradition. He has developed further the geometry of the 'sona' introducing the concept of mirror curves and inventing Lunda-designs, presented for the first time in (Gerdes 1990). Inspired by this research, Slavik Jablan (Belgrade, Serbia) has studied mirror curves and their relationship with mathematical knot theory (Jablan 1995, 2001); Robert Lange (Brandeis University, USA) developed 'sona tiles' in the early 1990s; Franco Favilli and his student Laura Maffei at the University of Pisa (Italy) have been developing software for the construction of mirror curves and Lunda-designs; and Mark Schlatter (Centenary College of Louisiana, USA) is studying mirror curves and permutations. Nils Rossing (University of Science and Technology, Trondheim, Norway) and Christoph Kirfel (2003) applied methods of 'sona' analysis by mirror curves to the mathematical analysis of a class of traditional Norwegian mats. Gerdes himself advanced with the study of Lunda-designs and a sub-class called Liki-designs, and found several interesting classes of matrices, like cyclic, helix, cylinder and chess-board matrices. Several of his papers are available in on-line journals (1998, 1999b, 2002c-g). Other links with determinants and magic squares were established (2000, 2002i). The newness and the multiple relationships of mathematical ideas arising from the analysis of the 'sona' tradition with other areas of mathematics reflects the profoundness and the mathematical fertility of the ideas of the Cokwe master drawers.

6.1 Further Sources on Numeration in Africa : Duodecimal
Numeration in Nigeria
In addition to the sources on numeration systems in Africa presented in AMUCHMA 9, AMUCHMA 22:4, and AMUCHMA 23:6.1, the following sources give information on duodecimal numeration in Nigeria:
Bouquiaux, Luc: A propos de numération:
L'emploi du système décimal et du systéme
duodécimal dans la langue birom (Nigéria septentrional),
Africana Linguistica, Tervuren, 1962, 7-10
Webmaster's Note: As certain symbols must be made as graphic images, the reproduction of the next table as a web page is not quite faithful. The pdf version of the entire document is better.
Mathews, H.F.: Duodecimal numeration in Northern Nigeria, The Nigerian Field, and Notes on the Nungu tribe, Nassawara Province, Northern Nigeria, and the neighboring tribes which use the duodecimal system of numeration, Harvard African Studies, 1917, Vol. 1, 83-93.
The author, a colonial assistant district commissioner, describes (pages 92-93) the numeration systems used by the Nungu and by neighboring peoples like the Ninzam on the north, the four clans known as the Artum, Barrku, Burrza, and Upye on the east, and the people known collectively as the Mada on the south. Reproduction of pages 92 and 93:
"All these tribes use the duodecimal system of counting, as do also a number of others living to the north and northeast i.e. along the bottom and top of the western escarpment of the Bauchi Plateau. I have had no opportunity of investigating the geographical limits of the system of duodecimal numeration. None of the tribes have any system of writing. The various languages extend over very limited areas and shade off at the edges into the neighboring ones. A native traveling twenty miles from his village would in most cases have great difficulty in making himself understood. This appears to be due to two causes: first, the languages, not having been reduced to writing, tend to alter rapidly; and second, the mutual distrust and hostility between villages and tribes restrict intercourse so much that the alterations are quite local, and the languages tend to diverge. Owing to the primitive character of the people, and to the limited time at my disposal for such researches, I have been unable to collect very large vocabularies, or to get sufficient data to compare fully the various inflexions, particles, prefixes, and suffixes they employ, but I have collected enough to show that the languages are very varied both in grammar and vocabulary. I have also been able to compare the numerals in four of the languages, namely, Nungu, South Mada, Mama, and Ninzam and have made the appended comparative table. I have drawn certain conclusions from the data given thereby, and these conclusions I will first state and then explain. My conclusions are: (10 originally the tribes from which the present ones are descended used a quinary, and then a decimal system of numeration, (2) that at a comparatively recent date some influences, which affected a large area comprising many tribes, introduced words for eleven and twelve on which, with their previous decimal system, were built the present duodecimal vocabularies. This introduction was not only original, but was a stroke of genius, for it produced a system which is far more convenient than the decimal system, the twelve-group being divisible by two, three, four, and six whereas the ten-group is only divisible by two and five."
"The data which seem to support the two conclusions are as follows. Even at the present day there remain sufficient indications that the numbers from six to nine were originally formed by some sort of compounding of five with the numbers from one to four respectively the essential characteristic of a quinary system. The Nungu shows this least. But even here we see ata (=5) with tamba (=7). It is true that the termination ba (=2), very common around the Niger-Benue confluence, seems to be lost here, unless it emerges in the Mama word bari. We have also a similarity between anne (=4) and isane (=9)."
"In South mada the words from six to nine have af- in common for their first syllable, and four and nine are enye and afwunyei respectively."
"In mama we have bari (=2) and tañzabari (=7), iyenu (=4) and tinzhenu (=9). These last two are even more closely allied than the spelling indicates, for the actual difference is very slight between the sounds which in the formar was reduced in writing to iy- and in the latter to zh-. In each the tongue is in contact with the palate, and the teeth are not closed, the regulating shade of difference seeming to be determined by the first syllabe in tinzhenu."
"In Ninzam there is etoñi (=5) which with iri (=1) seems to give tañre (=6). With the above-mentioned ba termination for two, eton (=5) gives tañba (=7), while with itra (=3) gives tandra (=8)."
"Further, it is noticed that although the numerals from one to ten in the respective languages differ widely, the numerals for eleven and twelve have an obvious similarity. Thus, eleven in Nungu is opo; in South Mada helaiobo (the last two syllables therefore equivalating opo); in Mama po, and in Ninzam ipo. Twelve is in Nungu oso; in South Mada eswo; in Mama so, and in Ninzam tso. It seems natural, therefore, to infer that these two numerals for eleven and twelve have not been influenced by the causes making for divergence to anything like the extent that the other ten have. But as the only cause discernible is the passage of time, it would seem (unless these conclusions are refuted by data collected from the remaining tribes in the future) that the names for eleven and twelve must be comparatively modern additions to what were formerly, as shown by internal evidence, quinary and decimal systems."
"The decimal system is now being very gradually reverted to by dropping the numerals for eleven and twelve and forming the higher number on multiples of ten. This is due to increasing intercourse with the Hausa and Yoruba traders and the surrounding tribes which, until the establishment of the British administration, did not dare to enter these parts."

Review by Claudia Zaslavsky (Author of Africa Counts [#20, 199, 283]) of Paulus Gerdes' Awakening of Geometrical Thought in Early Culture, MEP-Publications, Minneapolis MN, 2003, 200 pages (ISBN 930656-75-X). [Foreword by Dirk Struik (MIT)]
Paulus Gerdes is the author of many books and articles in several languages dealing with ethnomathematics, the interface between mathematics and anthropology. For many years, he and his colleagues in Mozambique have been investigating and documenting the mathematics inherent in the daily activities of various African cultures. Among his recent books in English are Geometry From Africa: Mathematical and Educational Explorations (Mathematical Association of America) and Women, Art and Geometry in Southern Africa (Africa World Press).
With Awakening of Geometrical Thought in Early Cultures, Gerdes digs deeper into the origins of geometric concepts. In this book, a translation and revision of an earlier work in Portuguese and German, he investigates the mathematical thought "frozen" in the activities of early societies, relying on both literature and on observation of such current practices of mat- and basket-weaving and house building as have survived colonization.
Basic to his analysis is Engels' theory of "human labor" as the driving force in the construction of knowledge. Gerdes writes: "The dialectical interplay between active life and abstract thinking constitutes the motor of the development of geometry" (page 9). The ability to abstract the geometric properties of objects is the outcome of a lengthy historical development based on experience. People learned to apply geometric principles in their practical lives, to fulfill their human needs.
The role of labor is central to this development. As one among
several examples, Gerdes describes in detail the process of weaving
a basket, using a wealth of diagrams and other illustrations.
Over the generations, practitioners developed various styles of
weaving, giving rise to geometric shapes-squares, hexagons, circles,
cylinders. They found the optimal angles at which to fold the
strips to produce the desired effect. They discovered that symmetrical
shapes were not only the most practical, but also the most beautiful,
as illustrated by drawings of decorative designs of several different
societies. They observed and were influenced by phenomena in nature.
Gerdes applies a similar analysis to house building and other activities. What practical activities inspired the Egyptians to memorialize their kings with square-based pyramids? How did they carry out that amazing feat of ancient Egyptian mathematics, the derivation of the formula for the volume of a truncated pyramid? Here again, Gerdes describes the possible path to this achievement in the "material products of human labor and in their empirically discovered relationships" (page 126).
Much has been written about the early development of geometric concepts. Gerdes analyzes these writings and reveals their shortcomings, from "unscientific" mysticism to inadequate probing into the origins of geometric ideas.
With its clear exposition, its hitherto-untapped theoretical concepts, its wealth of drawings, diagrams, and other illustrations, and its many references to the literature, Awakening of Geometric Thought in Early Cultures will appeal to mathematicians, anthropologists, historians, philosophers, educators, the lay public, and students of many disciplines.

The study begins with an introduction on the city of Béjaïa, as a centre of contact between the Moslem and Christian worlds. It continues with the presentation of the various intellectual activities of this city in particular those that have a direct or indirect link with mathematics (logic, astronomy, inheritance, geography). Mathematical activities are presented through some authors having a link with Béjaïa and who are known through their production or their biography (al-Qurashi, Fibonacci).

This is the French translation of an important book of al-Khayyâm, that includes three chapters: the first contains an attempt of demonstration of the postulate of parallels. The second presents new definitions of the equality and the inequality of two proportions considered better than those given by Euclid in Book V of the "Elements." The third chapter deals with the composition of the proportions, which was an operation very useful for the astronomers.

"Accepting as a premise that numerical entities must be associated to the social reality in which they appear, this article exposes that ancient Egyptian fractions are considered to be expressions of the magnitude quantities which have been obtained after being equally shared-out. Taking into account this view, an exhausting analysis of the different cases collected in the table which appears in the Recto of the Rhind's papyrus has allowed as the reconstruction of the shared-out processes used by the scribe Ahmes. Such a process has been undoubtedly complex, due to the fact that, for each one of the situations collected in this table, the scribe must make those decisions which will help the realization of a real share-out under the most suitable conditions. This reconstruction has enabled us to interpret Egyptian fractions as the addition of the partial results obtained when the share-out must be carried out following consecutive stages, as well as to devise two possible alternatives about the way in which the scribe would execute the numerical calculations associated to the share-out process."

9.1 Death of Khalil Jaouiche
Khalil Jaouiche, French historian of mathematics of Egyptian origin died on September 2, 2002, in Paris at the age of 78. His works in the history of mathematics deal essentially with the continuation of the Greek tradition of Alexandria in Arab mathematics. In this context he published two important books:
* Le livre du Qarasn de Thabit Ibn Qurra, Brill, Leiden, 1976.
* La théorie des parallèles en pays d'Islam, Vrin, Paris, 1986 (#67, 146).
9.2 Election to the African Academy of Sciences (AAS)
In "recognition of his distinguished career and achievements", AMUCHMA's Chairman Paulus Gerdes was elected a Fellow of the African Academy of Sciences. The AAS Governing Council approved his election in November 2002. He became the first Mozambican scholar to be elected to the AAS.
