Bringing together a team of international scholars with an interest in urban transformations, spatial justice and territoriality, this volume questions how the interstice is related to the emerging processes of partitioning, enclave-making and zoning, showing how in-between spaces are intimately related to larger flows, networks, territories and boundaries. Illustrated with a range of case studies from places such as the US, Quebec, the UK, Italy, Gaza, Iraq, India, and South-east Asia, the volume analyses the place and function of interstitial locales in both a ’disciplined’ urban space and a disordered space conceptualized through the notions of ’excess’, ’danger’ and ’threat’. Warning not to romanticize the interstice, the book invites us to study it as not simply a place but also a set of phenomena, events and social interactions. How are interstices perceived and represented? What is the politics of visibility that is applied to them? How to capture their peculiar rhythms, speeds and affects? On the one hand, interstices open up venues for informality, improvisation, challenge, and bricolage, playful as well as angry statements on the neoliberal city and enhanced urban inequalities. On the other hand, they also represent a crucial site of governance (even governance by withdrawal) and urban management, where an array of techniques ranging from military urbanism to new forms of value extraction are experimented. At the point of convergence of all these tensions, interstices appear as veritable sites of transformation, where social forces clash and mesh prefiguring our urban future. The book interrogates these territories, proposing new ways to explore the dynamics, events and visibilities that define them.

The present book provides a clear and comprehensive introduction to the topics of crystallography and diffraction for undergraduate and beginning graduate students and lecturers in physics, chemistry, materials and earth sciences, but will also be of interest to the layperson who wishes toknow about these topics beyond the level given in more general trade science books. The book shows how crystal structures may be built up from simple ideas of atomic packing and co-ordination, and develops the concepts of crystal symmetry, point and space groups by way of two-dimensional examples ofpatterns and tilings. Furthermore, the concept of the reciprocal lattice is explained in simple terms and its importance in an understanding of light, x-ray and electron diffraction shown. Finally, the book covers practical examples of the applications of these techniques, and describes theimportance of diffraction in the performance of optical instruments. For this second edition, the existing material has been thoroughly updated, additional figures and exercises have been supplied and two new chapters added. From reviews on the 1/e: '... This is a timely, well-constructed bookwhich should be seriously considered by every teacher of crystallography and can be recommended to anyone who wants to get to grips with crystallography and diffraction.' P. Goodhew, Journal of Microscopy, June 1998 'IUCr publications have always been outstanding for quality of presentation andexposition and this book maintains that high standard.' J.E. Chisholm, Mineralogical Magazine, February 1998

An introductory textbook on the structural principles of inorganic-chemical molecules and solids. Traditional concepts and modern approaches are considered and demonstrated with the aid of examples. The most important structural types are examined from different perspectives.
