NATIONAL BESTSELLER • “Steven Pressfield brings the battle of Thermopylae to brilliant life.”—Pat Conroy At Thermopylae, a rocky mountain pass in northern Greece, the feared and admired Spartan soldiers stood three hundred strong. Theirs was a suicide mission, to hold the pass against the invading millions of the mighty Persian army. Day after bloody day they withstood the terrible onslaught, buying time for the Greeks to rally their forces. Born into a cult of spiritual courage, physical endurance, and unmatched battle skill, the Spartans would be remembered for the greatest military stand in history—one that would not end until the rocks were awash with blood, leaving only one gravely injured Spartan squire to tell the tale. . . .

Norman Bruce Ream was born in southwestern Pennsylvania in 1844, the son of a farmer. He exhibited a commercial sense, but the Civil War interrupted his ambitions. Wounded twice, he returned home a hero. After some unsuccessful business ventures out west, he went to Chicago in 1871 and became a commission merchant in the Union Stockyards. A few years later, he moved uptown and traded grains and provisions in the pits of the Board of Trade. Money poured in. Indeed, by 1886 he was a millionaire (also married and the father of several children). He started investing in real estate, urban transit companies, railroad stock—and began consolidating and financing enterprises. At century’s end, he was traveling to New York City, impressing financiers like J. Pierpont Morgan. Indeed, he helped Morgan put together the U.S. Steel Corporation and the International Harvester Company, served on many boards, and even advised Morgan during the panic of 1907. But life grew turbulent. Public sentiment soured towards Wall Street and the wealthy. This, along with the presumed indiscretions of some of his children, kept his name in the press. He died in 1915, and gradually, his life was forgotten.

How much further should the affluent world push its material consumption? Does relative dematerialization lead to absolute decline in demand for materials? These and many other questions are discussed and answered in Making the Modern World: Materials and Dematerialization. Over the course of time, the modern world has become dependent on unprecedented flows of materials. Now even the most efficient production processes and the highest practical rates of recycling may not be enough to result in dematerialization rates that would be high enough to negate the rising demand for materials generated by continuing population growth and rising standards of living. This book explores the costs of this dependence and the potential for substantial dematerialization of modern economies. Making the Modern World: Materials and Dematerialization considers the principal materials used throughout history, from wood and stone, through to metals, alloys, plastics and silicon, describing their extraction and production as well as their dominant applications. The evolving productivities of material extraction, processing, synthesis, finishing and distribution, and the energy costs and environmental impact of rising material consumption are examined in detail. The book concludes with an outlook for the future, discussing the prospects for dematerialization and potential constrains on materials. This interdisciplinary text provides useful perspectives for readers with backgrounds including resource economics, environmental studies, energy analysis, mineral geology, industrial organization, manufacturing and material science.
Lock Gates and Other Closures in Hydraulic Projects shares the authors practical experience in design, engineering, management and other relevant aspects with regard to hydraulic gate projects. This valuable reference on the design, construction, operation and maintenance of navigation lock gates, movable closures of weirs, flood barriers, and gates for harbor and shipyard docks provides systematic coverage on all structural types of hydraulic gates, the selection of gate types, and their advantages and disadvantages. The discussion includes the latest views in new domains, such as environmental impact of hydraulic gate projects, sustainability assessments, relation with the issues of global climate change, handling accidents and calamities, and the bases of asset management. Heavily illustrated, this reference provides a generous amount of case studies based on the author's own and their colleagues' experiences from recent projects in Europe, America and other continents. - Presents extensive coverage of the operational profiles of hydraulic closures, including gates in navigation locks, movable closures on river weirs, closures of flood barriers, spillway closures and valves, and more - Outlines the different structural types of hydraulic gates, including miter gates, vertical lift gates, flap and hinged crest gates, radial gates, rolling and barge gates, sector gates and many other - Clearly outlines the selection process for gates for navigation locks, river weirs, flood barriers, hydroelectric plants, shipyard docks and other hydraulic structures - Provides comprehensive discussion of design loads and other actions to which hydraulic gates may be subjected during their service life, followed by an overview of analysis methods and tools - Addresses the newest challenges and concerns in hydraulic gate projects, such as environmental impact of hydraulic gate projects, risk-based design, sustainability issues, handling accidents and calamities, and gate maintenance in view of asset management - Presents the experiences from many recent projects in Europe and America, including the rolling gates in large European sea locks, gates in the Panama Canal new locks, flood barriers in New Orleans and the Netherlands
