Thought experiments are performed in the laboratory of the mind. Beyond this metaphor it is difficult to say just what these remarkable devices for investigating nature are or how they work. Though most scientists and philosophers would admit their great importance, there has been very little serious study of them. This volume is the first book-length investigation of thought experiments. Starting with Galileo's argument on falling bodies, Brown describes numerous examples of the most influential thought experiments from the history of science. Following this introduction to the subject, some substantial and provocative claims are made, the principle being that some thought experiments should be understood in the same way that platonists understand mathematical activity: as an intellectual grasp of an independently existing abstract realm. With its clarity of style and structure, The Laboratory of the Mind will find readers among all philosophers of science as well as scientists who have puzzled over how thought experiments work.

The untold history of how Chicago served as an important site of innovation in environmental thought as America transitioned to modern, industrial capitalism. In Nature's Laboratory, Elizabeth Grennan Browning argues that Chicago—a city characterized by rapid growth, severe labor unrest, and its position as a gateway to the West—offers the clearest lens for analyzing the history of the intellectual divide between countryside and city in the United States at the end of the nineteenth century. By examining both the material and intellectual underpinnings of Gilded Age and Progressive Era environmental theories, Browning shows how Chicago served as an urban laboratory where public intellectuals and industrial workers experimented with various strains of environmental thinking to resolve conflicts between capital and labor, between citizens and their governments, and between immigrants and long-term residents. Chicago, she argues, became the taproot of two intellectual strands of American environmentalism, both emerging in the late nineteenth century: first, the conservation movement and the discipline of ecology; and second, the sociological and anthropological study of human societies as "natural" communities where human behavior was shaped in part by environmental conditions. Integrating environmental, labor, and intellectual history, Nature's Laboratory turns to the workplace to explore the surprising ways in which the natural environment and ideas about nature made their way into factories and offices—places that appeared the most removed from the natural world within the modernizing city. As industrialization, urbanization, and immigration transformed Chicago into a microcosm of the nation's transition to modern, industrial capitalism, environmental thought became a protean tool that everyone from anarchists and industrial workers to social scientists and business managers looked to in order to stake their claims within the democratic capitalist order. Across political and class divides, Chicagoans puzzled over what relationship the city should have with nature in order to advance as a modern nation. Browning shows how historical understandings of the complex interconnections between human nature and the natural world both reinforced and empowered resistance against the stratification of social and political power in the city.

With more than 250 million active users, Facebook is the world’s #1 social networking platform. But developing successful Facebook applications presents unique challenges, both technical and nontechnical. Now, two of the world’s most experienced Facebook developers show you exactly how to meet those challenges. Essential Facebook Development offers insider guidance and up-to-the-minute best practices for the entire application lifecycle: design, coding, testing, distribution, post-launch monitoring, metrics, and even application marketing. Using extensive real-world examples, John Maver and Cappy Popp reveal why some Facebook applications succeed brilliantly while others fail. Next, they walk through building a complete application using every major component of the Facebook platform. Maver and Popp thoroughly cover Facebook’s most important new features, including Facebook Connect, and provide extensive information available nowhere else–from measuring application success to monetization. Coverage includes Thorough introductions to Facebook’s current architecture, integration points, and development technologies Discussion of successful Facebook applications–and what makes them successful What every developer must know about Facebook’s Terms of Service Creating an effective application infrastructure Creating canvas pages with FBML and IFrames Adding support for profiles, application tabs, and messaging Incorporating JavaScript into Facebook applications with FBJS Integrating Facebook into external sites with Facebook Connect and the Facebook JavaScript Client Library Debugging techniques for Facebook applications Spreading, monitoring, and tuning applications

This highly original work presents laboratory science in a deliberately skeptical way: as an anthropological approach to the culture of the scientist. Drawing on recent work in literary criticism, the authors study how the social world of the laboratory produces papers and other "texts,"' and how the scientific vision of reality becomes that set of statements considered, for the time being, too expensive to change. The book is based on field work done by Bruno Latour in Roger Guillemin's laboratory at the Salk Institute and provides an important link between the sociology of modern sciences and laboratory studies in the history of science.
