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.

"Global Africa will complicate conventional views of Africa as a place of violence, despair and victimhood--a place and space that other people, states, and organizations act on and steal from. Instead, they aim to document some of the significant global connections, circulations, and contributions that African people, ideas, and goods have made in the world--not just in the United States, but in South Asia, Latin America, Europe, and elsewhere. They will showcase new framings of Africa, but will not romanticize the conditions and circumstances in which too many people on the continent currently live. The essays in this volume will amplify those voices that offer complex and insightful explanations, strategies for solutions, and inspiration for the future."--Provided by publisher.

The year’s finest mathematical writing from around the world This annual anthology brings together the year’s finest mathematics writing from around the world. Featuring promising new voices alongside some of the foremost names in the field, The Best Writing on Mathematics 2018 makes available to a wide audience many pieces not easily found anywhere else—and you don’t need to be a mathematician to enjoy them. These essays delve into the history, philosophy, teaching, and everyday aspects of math, offering surprising insights into its nature, meaning, and practice—and taking readers behind the scenes of today’s hottest mathematical debates. James Grime shows how to build subtly mischievous dice for playing slightly unfair games and Michael Barany traces how our appreciation of the societal importance of mathematics has developed since World War II. In other essays, Francis Su extolls the inherent values of learning, doing, and sharing mathematics, and Margaret Wertheim takes us on a mathematical exploration of the mind and the world—with glimpses at science, philosophy, music, art, and even crocheting. And there’s much, much more. In addition to presenting the year’s most memorable math writing, this must-have anthology includes an introduction by the editor and a bibliography of other notable pieces on mathematics. This is a must-read for anyone interested in where math has taken us—and where it is headed.

The poor economic performance of some African countries since independence has been a major concern to both African leaders and policy makers. This volume, which draws together contributions from academics based in Africa and its diaspora, situates the continent within its historic and socio-political background: from the 1960s, the decade of independence, through to its development outlook as the new millennium unfolds. It examines a broad range of contemporary issues -- from development and culture to linguistics and is unique in identifying and examining issues that are common both to Africa and the diaspora.

This text explores the multidisciplinary context of African Indigenous Knowledge Systems from scholars and scholar activists committed to the interrogation, production, articulation, dissemination and general development of endogenous and indigenous modes of intellectual activity and praxis. The work reinforces the demand for the decolonization of the academy and makes the case for a paradigmatic shift in content, subject matter and curriculum in institutions in Africa and elsewhere – with a view to challenging and rejecting disinformation and intellectual servitude. Indigenous intellectual discourses related to diverse disciplines take center stage in this volume with a focus on education, mathematics, medicine, chemistry and engineering in their historical and contemporary context.

Throughout history, nature has served as an inspiration for architecture and designers have tried to incorporate the harmonies and patterns of nature into architectural form. Alberti, Charles Renee Macintosh, Frank Lloyd Wright, and Le Courbusier are just a few of the well- known figures who have taken this approach and written on this theme. With the development of fractal geometry--the study of intricate and interesting self- similar mathematical patterns--in the last part of the twentieth century, the quest to replicate nature’s creative code took a stunning new turn. Using computers, it is now possible to model and create the organic, self-similar forms of nature in a way never previously realized. In Fractal Architecture, architect James Harris presents a definitive, lavishly illustrated guide that explains both the “how” and “why” of incorporating fractal geometry into architectural design.

It has been clear for many years that the ways in which archaeology is practised have been a direct product of a particular set of social, cultural, and historical circumstances - archaeology is always carried out in the present. More recently, however, many have begun to consider how archaeological techniques might be used to reflect more directly on the contemporary world itself: how we might undertake archaeologies of, as well as in the present. This Handbook is the first comprehensive survey of an exciting and rapidly expanding sub-field and provides an authoritative overview of the newly emerging focus on the archaeology of the present and recent past. In addition to detailed archaeological case studies, it includes essays by scholars working on the relationships of different disciplines to the archaeology of the contemporary world, including anthropology, psychology, philosophy, historical geography, science and technology studies, communications and media, ethnoarchaeology, forensic archaeology, sociology, film, performance, and contemporary art. This volume seeks to explore the boundaries of an emerging sub-discipline, to develop a tool-kit of concepts and methods which are applicable to this new field, and to suggest important future trajectories for research. It makes a significant intervention by drawing together scholars working on a broad range of themes, approaches, methods, and case studies from diverse contexts in different parts of the world, which have not previously been considered collectively.
