Book Description
Essays on photography and the medium's history and evolving identity. In Each Wild Idea, Geoffrey Batchen explores a wide range of photographic subjects, from the timing of the medium's invention to the various implications of cyberculture. Along the way, he reflects on contemporary art photography, the role of the vernacular in photography's history, and the Australianness of Australian photography. The essays all focus on a consideration of specific photographs—from a humble combination of baby photos and bronzed booties to a masterwork by Alfred Stieglitz. Although Batchen views each photograph within the context of broader social and political forces, he also engages its own distinctive formal attributes. In short, he sees photography as something that is simultaneously material and cultural. In an effort to evoke the lived experience of history, he frequently relies on sheer description as the mode of analysis, insisting that we look right at—rather than beyond—the photograph being discussed. A constant theme throughout the book is the question of photography's past, present, and future identity.

Flow and Reactions in Permeable Rocks
Author: O. M. PhillipsPublisher: Cambridge University Press
ISBN: 9780521380980
Category : Nature
Languages : en
Pages : 300
Book Description
The formation of ore deposits and the patterns of mineral alteration in rocks frequently involves the transport of large amounts of dissolved solids, sometimes transiently, but often over long periods of time. Knowing or suspecting this, we logically seek to resolve several questions: What are the large- and small-scale patterns of flow in geological materials? What is the direction and rate of flow in a given structure? What factors control the rates of chemical reaction within the rocks? What governs the dissolution of materials in some regions and their deposition in other areas that, over eons, leads to the distribution of minerals we see today? The search for answers to these issues involves a combination of approaches and subjects that includes geochemistry, structural geology, and fluid mechanics. In Flow and Reactions in Permeable Rocks, Dr. Owen Phillips provides the first book-length work that connects these different fields of study and applies them to the problem of flow and flow-controlled reaction in rocks. The author begins by specifying the general physical and chemical principles that govern fluid flow and chemical reactions in rocks. He then develops the theoretical underpinnings for a variety of different patterns of flow and for the three basic types of flow-controlled reaction: fronts, gradient reactions, and reactions in mixing zones. In the next chapter he explores some conditions for stability and instability in fluid flow, for instance the conditions under which one state of flow pattern spontaneously evolves into another. Finally, Dr. Phillips describes in detail the two great driving forces of large-scale fluid circulation in rocks: pressure differences and thermal convection. Typical geological examples are given and, wherever possible, compared to numerical results or field observations. The analytical developments require some familiarity with college-level mathematics, but derivations are easy to follow or may even be skipped by the trusting reader.
The Cornish Overseas

Book Description
In this fully revised and up-dated edition of The Cornish Overseas, Philip Payton draws upon almost two decades of additional research undertaken by historians the world over since the first paperback version of this book was published in 2005. Now published by University of Exeter Press, this edition of Philip Payton’s classic history of Cornwall’s ‘great emigration’ takes account of numerous new sources to present a comprehensive, definitive picture of the Cornish diaspora. The Cornish Overseas begins by identifying some of the classic themes of Cornish emigration history, including Cornwall’s ‘emigration culture’ and ‘emigration trade’, and goes on to sketch early Cornish settlement in North America and Australia. The book then examines in detail the upsurge in Cornish emigration after 1815, showing how Cornwall became swiftly one of the great emigration regions of Europe. Discoveries of silver, copper and gold drew Cornish miners to Latin America, while Cornish agriculturalists were attracted to the United States and Canada. The discoveries of copper in South Australia and in Michigan during the 1840s offered new destinations for the emigrant Cornish, as did the Californian gold rush in 1849 and the Victorian gold rush in Australia in 1851. The crash of copper-mining in Cornwall in 1866 sped further waves of emigrants to countries as disparate as New Zealand and South Africa. In each of these places the Cornish remained distinctive as ‘Cousin Jacks’ and ‘Cousin Jennys’, establishing their own communities and making important contributions to the social, political and economic development of the new worlds. By 1914, however, Cornwall was no longer the international centre of mining expertise, the mantle having passed to America, Australia and South Africa, and Cornish emigration had dwindled as a result. Nonetheless, the Cornish at home and abroad remained aware of their global transnational identity, an identity that has been revitalised in the late twentieth and early twenty-first centuries.
