Fractals are characterized by the repetition of similar patterns at ever-diminishing scales. Fractal geometry has emerged as one of the most exciting frontiers on the border between mathematics and information technology and can be seen in many of the swirling patterns produced by computer graphics. It has become a new tool for modeling in biology, geology, and other natural sciences. Anthropologists have observed that the patterns produced in different cultures can be characterized by specific design themes. In Europe and America, we often see cities laid out in a grid pattern of straight streets and right-angle corners. In contrast, traditional African settlements tend to use fractal structures-circles of circles of circular dwellings, rectangular walls enclosing ever-smaller rectangles, and streets in which broad avenues branch down to tiny footpaths with striking geometric repetition. These indigenous fractals are not limited to architecture; their recursive patterns echo throughout many disparate African designs and knowledge systems. Drawing on interviews with African designers, artists, and scientists, Ron Eglash investigates fractals in African architecture, traditional hairstyling, textiles, sculpture, painting, carving, metalwork, religion, games, practical craft, quantitative techniques, and symbolic systems. He also examines the political and social implications of the existence of African fractal geometry. His book makes a unique contribution to the study of mathematics, African culture, anthropology, and computer simulations.

This fascinating study of mathematical thinking among sub-Saharan African peoples covers counting in words and in gestures; measuring time, distance, weight, and other quantities; manipulating money and keeping accounts; number systems; patterns in music, poetry, art, and architecture; and number magic and taboos. African games such as mankala and elaborate versions of tic-tac-toe show how complex this thinking can be. An invaluable resource for students, teachers, and others interested in African cultures and multiculturalism, this third edition is updated with an introduction covering two decades of new research in the ethnomathematics of Africa.

"A groundbreaking scholarly publication, accompanying an exhibition organized by the National Museum of African Art, Smithsonian Institution, African Cosmos- Stellar Artsbrings together exceptional works of art, dating from ancient times to the present, and essays by leading scholars and contemporary artists to consider African cultural astronomy- creativity and artistic practice in Africa as it is linked to celestial bodies and atmospheric phenomena. African concepts of the universe are intensely personal, placing human beings in relation to the earth and sky, and with the sun, moon, and stars. At the core of creation myths and the foundation of moral values, celestial bodies are often accorded sacred capacities and are part of the “cosmological map” that allows humans to chart their course through life."

Kuba Textiles and Design is an engaging introduction to one of the most unusual and fascinating of all African arts. The textiles of the Kuba people of the Democratic Republic of Congo are decorated not with human or animal figures, but with astonishing abstract designs. Although the Kuba have been producing these textiles for four hundred years, there is something strikingly modern about their aesthetic. A perfect entry point for casual readers and a gift to collectors hoping to learn more about the pieces they treasure.

How the presence of the tsetse fly turned the African forest into an open laboratory where African knowledge formed the basis of colonial tsetse control policies. The tsetse fly is a pan-African insect that bites an infective forest animal and ingests blood filled with invisible parasites, which it carries and transmits into cattle and people as it bites them, leading to n'gana (animal trypanosomiasis) and sleeping sickness. In The Mobile Workshop, Clapperton Chakanetsa Mavhunga examines how the presence of the tsetse fly turned the forests of Zimbabwe and southern Africa into an open laboratory where African knowledge formed the basis of colonial tsetse control policies. He traces the pestiferous work that an indefatigable, mobile insect does through its movements, and the work done by humans to control it. Mavhunga's account restores the central role not just of African labor but of African intellect in the production of knowledge about the tsetse fly. He describes how European colonizers built on and beyond this knowledge toward destructive and toxic methods, including cutting down entire forests, forced “prophylactic” resettlement, massive destruction of wild animals, and extensive spraying of organochlorine pesticides. Throughout, Mavhunga uses African terms to describe the African experience, taking vernacular concepts as starting points in writing a narrative of ruzivo (knowledge) rather than viewing Africa through foreign keywords. The tsetse fly became a site of knowledge production—a mobile workshop of pestilence.

Every year, millions of Americans visit planetariums and are captivated by their strikingly realistic portrayal of the night sky. Today, it is indeed difficult to imagine astronomy education without these magnificent celestial theaters. But projection planetariums, first developed in Germany, have been a part of American museum pedagogy only since the early twentieth century and were not widespread until the 1960s. In this unique social history, former planetarium director and historian of science Jordan D. Marché II offers the first complete account of the community of individuals and institutions that, during the period between 1930 and 1970, made planetariums the popular teaching aids they are today. Marché addresses issues such as the role of gender and social developments within the planetarium community, institutional patronage, and the popularization of science. He reveals how, at different times, various groups, including financial donors, amateur scientists, and government officials, viewed the planetarium as an instrument through which they could shape public understanding and perceptions of astronomy and space science. Offering an insightful, wide-ranging look into the origins of an institution that has fascinated millions, Theaters of Time and Space brings new perspectives to how one educational community changed the cultural complexion of science, helped shape public attitudes toward the U.S. space program, and even contributed to policy decisions regarding allocations for future space research.
