Why does one smoker die of lung cancer but another live to 100? The answer is 'The Hidden Half' - those random, unknowable variables that mess up our attempts to comprehend the world. We humans are very clever creatures - but we're idiots about how clever we really are. In this entertaining and ingenious book, Blastland reveals how in our quest to make the world more understandable, we lose sight of how unexplainable it often is. The result - from GDP figures to medicine - is that experts know a lot less than they think. Filled with compelling stories from economics, genetics, business, and science, The Hidden Half is a warning that an explanation which works in one arena may not work in another. Entertaining and provocative, it will change how you view the world.

The role of objects and images in everyday life are illuminated incisively in Material Vernaculars, which combines historical, ethnographic, and object-based methods across a diverse range of material and visual cultural forms. The contributors to this volume offer revealing insights into the significance of such practices as scrapbooking, folk art produced by the elderly, the wedding coat in Osage ceremonial exchanges, temporary huts built during the Jewish festival of Sukkot, and Kiowa women's traditional roles in raiding and warfare. While emphasizing local vernacular culture, the contributors point to the ways that culture is put to social ends within larger social networks and within the stream of history. While attending to the material world, these case studies explicate the manner in which the tangible and intangible, the material and the meaningful, are constantly entwined and co-constituted.
