On Weathering

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.

Our landscape is constantly changing, but before the dramatic effects of erosion and mass movement take place, more subtle forces work on the rocks, minerals and soils around us. Weathering is the initial process which exposes the top few layers of the Earth to the potential for change. This book provides an introduction to the scientific principles behind mechanical, chemical and biological weathering. Starting with a consideration of the chemical and physical properties of rocks and water, the authors proceed to an accessible explanation of the weathering processes themselves, concluding with a review of weathering rates and intensities, and a survey of the effects of weathering on the landscape. Assuming little background knowledge, the authors develop ideas from first principles to provide a straightforward introduction to weathering for students of geography, geology and earth and environmental science.

A New York Times Notable Book of the Year. Pearl doesn't know how she's ended up in the river--the same messy, cacophonous river in the same rain-soaked valley she'd been stuck in for years. But here her spirit swirls and stays . . . Ada, Pearl's daughter, doesn't know how she's ended up back in the house she left thirteen years ago--with no heating apart from a fire she can't light, no way of getting around apart from an old car she's scared to drive, and no company apart from her own young daughter, Pepper. She wants to clear out Pearl's house so she can leave and not look back. Pepper has grown used to following her restless mother from place to place, but this house, with its faded photographs, its boxes of cameras and its stuffed jackdaw, is something new. Fascinated by the scattering of people she meets, by the river that unfurls through the valley, and by the strange old woman who sits on the bank with her feet in the cold, coppery water, Pepper doesn't know why anyone would ever want to leave. As the first frosts of autumn herald the coming of a long winter and Pepper and Ada find themselves entangled with the life of the valley, with new companions who won't be closed out, each will discover the ways that places can take root inside us, bind us together, and become us.

'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

Volume 31 of Reviews in Mineralogy reviews current thinking on the fundamental processes that control chemical weathering of silicates, including the physical chemistry of reactions at mineral surfaces, the role of experimental design in isolating and quantifying these reactions, and the complex roles that water chemistry, hydrology, biology, and climate play in weathering of natural systems. The chapters in this volume are arranged to parallel this order of development from theoretical considerations to experimental studies to characterization of natural systems. Secondly, the book is meant to serve as a reference from which researchers can readily retrieve quantitative weathering rate data for specific minerals under detailed experimental controls or for natural weathering conditions. Toward this objective, the authors were encouraged to tabulate available weathering rate data for their specific topics. Finally this volume serves as a forum in which suggestions and speculations concerning the direction of future weathering research are discussed.

Soil science is perhaps one of the oldest practical sciences, having been of concern to man probably from the time he progressed from a strictly preda tory life to one in which agriculture became important. In view of the anti quity of concern with the subject, it is perhaps surprising that it can be approached from a fresh viewpoint, as is done in this book. Because soil science is an applied science, it is not surprising that the approach is usually descriptive, rather than imaginative. For agriculturalists and other land users, perhaps the most important part of soil science is the description of soils and the capacities of such soils to maintain crops, and this is reflected by the fact that soil science is usually treated ima highly descriptive manner, with soil classification being one of the main efforts. The treatment of the subject from a geological point of view, with considerable emphasis on the evolution of soils and the reasons governing their composition and form, makes this a highly readable book. Books on soil science are timely, with present-day concern with such major problems as the pollution of our environment and the possibility of overreaching our capacity for producing food for an expanding population.
