Weathering

Describes how scientists learn about the earth by studying different kinds of rocks and how they weather and erode.

This series offers a detailed, informative and lively discussion on four of the key areas of physical geography. Each book helps develop the knowledge of how specific features of the Earth are formed, their causes and effects, patterns and processes, and our study and understanding of them. The series aims not only to answer, but also to inspire questions about different environments and landscapes, and our relationships with some of the greatest forces of nature we experience on Earth. Photographs bring the effects of the subject vividly to life, while diagrams enhance the readers' practical understanding of the processes that have created the landscapes of the world in which we live today.

On Weathering illustrates the complex nature of the architectural project by taking into account its temporality, linking technical problems of maintenance and decay with a focused consideration of their philosophical and ethical implications.In a clear and direct account supplemented by many photographs commissioned for this book, Mostafavi and Leatherbarrow examine buildings and other projects from Alberti to Le Corbusier to show that the continual refinishing of the building by natural forces adds to, rather than detracts from, architectural meaning. Their central discovery, that weathering makes the "final" state of the construction necessarily indefinite, challenges the conventional notion of a building's completeness. By recognizing the inherent uncertainty and inevitability of weathering and by viewing the concept of weathering as a continuation of the building process rather than as a force antagonistic to it, the authors offer alternative readings of historical constructions and potential beginnings for new architectural projects.

This report describes the theory of weathering and its effect on polymer properties, methods of stabilisation, and natural and accelerated weathering tests. The problems associated with particular polymers used in outdoor applications are explained. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

This volume is intended to provide an up-to-date overview of the approaches, methodologies and techniques devoted to better understand-ing of the weathering conditions of rock masses on slopes. According to the local conditions, a variety of slope movements may take place and involve weathered rock masses. Shallow and rapid soil slips evolving to debris flows are probably the most common type of slope movement. At the same time, deep-seated, intermittent landslides can also affect large volumes of weathered rocks and soils. Despite the high frequency of landslides in weathered materials, and the damage and casualties they repeatedly cause, little is known about the relationship between weathering and slope move-ments. This book presents worldwide case studies, where a variety of geo-logical and geomorphological settings are discussed. The content is divided into three sections: the first is devoted to broad aspects of the weathering/landslide processes; the second and third sections include papers dealing with igneous/metamorphic and sedimentary weathered rocks, respec-tively.

'It's not just the body that changes: Fashions and hairstyles evolve; pets come and go; typewriters, analog clocks, and telephones with cords disappear; and finally, film gives way to digital and the computer replaces the darkroom. While Weathering Time is a personal archive, and I am mining the archive to address issues of the female body, the family snapshot and loss, I am also interested in producing images that suggest some of the experiences of my generation. Indeed, the photographs underscore the cultural, technological, and physical changes that have occurred over the past thirty-five years--from my youth to the dawn of my old age.' Nancy Floyd
