An investigation into how machines and living creatures fly, and of the similarities between butterflies and Boeings, paper airplanes and plovers. From the smallest gnat to the largest aircraft, all things that fly obey the same aerodynamic principles. In The Simple Science of Flight, Henk Tennekes investigates just how machines and creatures fly: what size wings they need, how much energy is required for their journeys, how they cross deserts and oceans, how they take off, climb, and soar. Fascinated by the similarities between nature and technology, Tennekes offers an introduction to flight that teaches by association. Swans and Boeings differ in numerous ways, but they follow the same aerodynamic principles. Biological evolution and its technical counterpart exhibit exciting parallels. What makes some airplanes successful and others misfits? Why does the Boeing 747 endure but the Concorde now seem a fluke? Tennekes explains the science of flight through comparisons, examples, equations, and anecdotes. The new edition of this popular book has been thoroughly revised and much expanded. Highlights of the new material include a description of the incredible performance of bar-tailed godwits (7,000 miles nonstop from Alaska to New Zealand), an analysis of the convergence of modern jetliners (from both Boeing and Airbus), a discussion of the metabolization of energy featuring Lance Armstrong, a novel treatment of the aerodynamics of drag and trailing vortices, and an emphasis throughout on evolution, in nature and in engineering. Tennekes draws on new evidence on bird migration, new wind-tunnel studies, and data on new airliners. And his analysis of the relative efficiency of planes, trains, and automobiles is newly relevant. (On a cost-per-seat scale, a 747 is more efficient than a passenger car.)

In Discovering the Possible Luca Meldolesi recounts over half a century of Hirschman's work, exploring the motivations, methodology, and unexpected developments of his research. Published simultaneously in Italian, Spanish, and English, Discovering the Possible is the first book to probe the whole corpus of Hirschman's work and to highlight the wealth of his ideas and the sharp self-irony with which his intuitions are forged into thoughts. The book will interest students and professionals in economics, sociology, political science, and moral philosophy, as well as those who focus on the development sector of these disciplines.

Many coastal communities have built structures at their beaches and added quantities of sand in contoured designs to combat erosion. Are such beach nourishment projects technically and economically sound? Or are they nothing more than building sand castles, as critics claim? Beach Nourishment and Protection provides a sound technical basis for decisionmaking, with recommendations regarding the utility of beach nourishment, the appropriate role of federal agencies, responsibility for cost, design methodology, and other issues. This volume Examines the economic and social role of beaches, the history of beach nourishment projects, and management strategies for shore protection. Discusses the role of the U.S. Army Corps of Engineers and other federal agencies, with a close-up look at the federal flood insurance program. Explores the state of the art in project design and prediction of outcomes, including the controversy over the use of traditional and nontraditional shore protection devices. Addresses what is known about the environmental impacts of beach nourishment. Identifies what outcomes should be targeted for continued monitoring by project officials. Beach Nourishment and Protection provides insight into the technical, economic, environmental, and policy implications of beach nourishment and protection, with examples and suggested research directions.
