davi: Infrastructure: A Field Guide to the Industrial Landscape
Brian Hayeshttp://www.amazon.com/gp/product/0393329593/ref=pd_lpo_k2_dp...This book is a "how it works" guide to the infrastructure of modernity: the power grid, mining, steel production, etc. Great photographs & readable text. I read it cover to cover and was enriched thereby.
