String Figures as Mathematics?

Eric Vandendriessche has obtained the French "Agrégation" of mathematics (1992). In 2010, he received his Ph.D. in History and Philosophy of Sciences from Paris Diderot University. Eric Vandendriessche is a member of the Sciences–Philosophy–History French laboratory (UMR SPHERE 7219 – CNRS & Paris Diderot University). He is currently carrying out research in ethnomathematics, doing fieldwork in Papua New Guinea and Vanuatu (Melanesia, South Pacific). The aim of his work is to study the mathematical rationality that underlies activities involving geometrical and algorithmic practices (such as string figure-making or sand-drawing in Oceania), while attempting to analyze how the practitioners of these activities conceive - or have conceived - them in societies of oral tradition. Eric vandendriessche is in charge of the "String figures: cultural and cognitive aspects of a mathematical practice" research program (2012–2015), financially supported by the city of Paris (program "Emergences" 2011).

"Vandenessche (Paris Diderot Univ., France) divides the volume-which is really many books in one-into four parts: 'How to Study String Figure-Making,' 'Mathematics and String Figures,' 'Analysing String Figure Algorithms,' and 'String Figures in the Field.' ... Summing Up: Highly recommended. Upper-division undergraduates through faculty and professionals." (D. V. Feldman, Choice, Vol. 53 (3), November, 2015) "Vandendriessche gives a mathematical analysis of string figure-making. ... The author does recommend that every reader try following his instructions to create some of the string figures. I found his instructions clear and the multicolored pictures helpful. ... Anthropologists and ethnomathematicians will benefit from the richness of Vandendriessche's discussion." (Joel Haack, MAA Reviews, March, 2015)
