2.4 Colloquium dedicated to (10-13 July, Safi, Morocco)
On the occasion of the sixtieth birthday of the mathematician Mohamed Akkar, his former students, led by Mohamed Chidami, one of the Vice-president of the African Mathematical Union (AMU), organized an international colloquium on "Statistics in functional spaces" that took place in his home town Safi. Morrocco's Minister of the National Education and Secretary of State for Scientific Research attended the opening session of the colloquium and the ceremony of honoring. About one hundred scholars mostly from Morocco but also from Algeria, Benin, Burkina Fasso, France, Germany, Poland, and South Africa took part. Jan Persens, President of AMU, gave the closing address. Twenty five papers on statistics in connection with functional analysis and four papers of general interest were presented. Ahmed Djebbar (Algeria) presented the paper entitled "Debates and controversies among Arabic mathematicians (9th-14th centuries)."

"The first part of the paper analyses the archaeological, ethnohistorical and linguistic evidence that led the author to propose that in the 14th 15th centuries the Berber populations of Grand Canary Island systematically recorded numerical, astronomical and calendrial data by means of certain geometrical figures named tara, painted in white, red and black on wooden planks and on the walls of certain caves. One main conclusion of the study was the discovery of the use of a type of chess board of 3 vertical x 4 horizontal squares, named acano by the author, to represent 12 moons" (CF. AMUCHMA 19: 4.1).
#351 Barrios García, José: Tara: A study

chess board, in: C. Jaschek and F. Atrio Barandela (Eds.), Proceedings
of the IVth SEAC meeting "Astronomy and Culture",
Universidad de Salamanca, Salamanca (Spain), 1997, 47-54 [SEAC
= Société Européenne pour l'Astronomie dans
la Culture, European Society for Astronomy in Culture]
The paper presents the acano as a Berber lunar calendar and shows "how to number its squares to force the solstitial, equinoctial and eclipse moons to move across the board with very simple and stable patterns. These patterns provide a safe and clear mnemonic guide for performing on the acano an easy calculus of seasonal and eclipse moons over extended periods of time, just using the difference in days of the lunar year with either the solar year or the eclipse year to perform an elementary saw function on the squares. This calculus establishes the octaeteris, the metonic cycle and the 135-moon eclipse cycle as basic periods of the acano. The proposed calculus on the acano would reveal an unsuspected high level of Canarian mathematical astronomy [in the 14th - 15th centuries] and pose the question of the origin of this set of techniques" (CF. AMUCHMA 19: 4.1).
#352 DeYoung, Gregg: Astronomy in Ancient Egypt, in: Helaine
Selin (Ed.), Astronomy across Cultures, The History of Non-Western
Astronomy, Kluwer Academic Publishers, Dordrecht, 2000, 475-508
"Ancient Egypt had a wide-ranging but essentially qualitative understanding of the heavens. The regularity of the annual inundations removed the necessity to make extensive predictions of future meteorological or climatological events. Despite making extensive observations, the reliance on extremely simple observational devices effectively prevented the growth of any complex theories or predictive algorithms. The primary concern seems to have been connected with time measurement, both for agricultural and religious purposes, as well as articulating analogies that were taken to point toward the possibility of a future life through constant rebirth, like the celestial lights" (p. 507).

#363 Lumpkin, Beatrice: Mathematics used in Egyptian Construction
and Bookkeeping, The Mathematical Intelligencer, New York,
2002, Vol. 24 No. 2, 20-25
Presents "examples from ancient construction and bookkeeping practices [which] indicate that the development of relatively modern concepts, such as recognition of zero as a quantity and the metricizing of space, has a long history, going back at least 4,700 years in ancient Egyptian mathematics. The examples include a bookkeeping balance sheet with many columns containing zero remainders and numbered construction lines at pyramids and mastabas. The same symbol, nfr, was used for the zero remainders and the zero reference point on the construction guidelines. A third example was a very interesting architect's diagram that gave vertical coordinates for points located on a curve. The horizontal spacing of the points appears to be one cubit apart."
#364 Rossi, Corinna & Christopher A. Tout: Were the Fibonacci
Series and the Golden Section Known in Ancient Egypt, Historia
Mathematica, New York, Vol. 29, 2002, 101-113
"The Fibonacci series and the Golden Section have often been used to explain the proportions of ancient Egyptian art and architecture. All such theories, however, are based on our modern mathematical system. They have never been examined in the realm of ancient Egyptian mathematics, as we understand it from studying the surviving mathematical sources. This article analyses the compatibility of the Fibonacci series with ancient Egyptian mathematics and suggests how an ancient scribe could have handled it. The conclusion is that concepts such as phi and the convergence to phi have little in common with the surviving ancient Egyptian mathematical documents and that they are quite far from the ancient Egyptian mentality" (p. 101)
