On January 5, 1845, the Prussian Cultural Minister received a request by a group of six young men to form a new Physical Society in Berlin. In fields from thermodynamics, mechanics, and electromagnetism to animal electricity, ophthalmology, and psychophysics, members of this small but growing group--which soon included Emil Du Bois-Reymond, Ernst Brucke, Werner Siemens, and Hermann von Helmholtz--established leading positions in what only thirty years later had become a new landscape of natural science. How was this possible? How could a bunch of twenty-somethings succeed in seizing the future? In Aesthetics, Industry, and Science, M. Norton Wise answers these questions not simply from a technical perspective of theories and practices but with a broader cultural view of what was happening in Berlin at the time. He emphasizes in particular how rapid industrial development, military modernization, and the neoclassical aesthetics of contemporary art informed the ways in which these young men thought. Wise argues that aesthetic sensibility and material aspiration in this period were intimately linked, and he uses these two themes for a final reappraisal of Helmholtz's early work. Anyone interested in modern German cultural history, or the history of nineteenth-century German science, will be drawn to this landmark book.

"The Values of Precision" examines how exactitude has come to occupy such a prominent place in Western culture. What has been the value of numerical values? Beginning with the late eighteenth century and continuing into the twentieth, the essays in this volume support the view that centralizing states--with their increasingly widespread bureaucracies for managing trade, taxation, and armies--and large-scale commercial enterprises--with their requirements for standardization and mass production--have been the major promoters of numerical precision. Taking advantage of the resources available, scientists and engineers have entered a symbiotic relationship with state and industry, which in turn has led to increasingly refined measures in ever-widening domains of the natural and social world. At the heart of this book, therefore, is an inquiry into the capacity of numbers and instruments to travel across boundaries of culture and materials.

Many of the papers focus attention on disagreements about the significance and the credibility of particular sorts of measurements deployed to support particular claims, as in the measures of the population of France, the electrical resistance of copper, or the solvency of insurance companies. At the same time they display the deeply cultural character of precision values. Contributors to the volume include Ken Alder, Graeme J. N. Gooday, Jan Golinski, Frederic L. Holmes, Kathryn M. Olesko, Theodore M. Porter, Andrea Rusnock, Simon Schaffer, George Sweetnam, Andrew Warwick, and M. Norton Wise.

Physicists regularly invoke universal laws, such as those of motion and electromagnetism, to explain events. Biological and medical scientists have no such laws. How then do they acquire a reliable body of knowledge about biological organisms and human disease? One way is by repeatedly returning to, manipulating, observing, interpreting, and reinterpreting certain subjects-such as flies, mice, worms, or microbes-or, as they are known in biology, "model systems." Across the natural and social sciences, other disciplinary fields have developed canonical examples that have played a role comparable to that of biology's model systems, serving not only as points of reference and illustrations of general principles or values but also as sites of continued investigation and reinterpretation. The essays in this collection assess the scope and function of model objects in domains as diverse as biology, geology, and history, attending to differences between fields as well as to epistemological commonalities.Contributors examine the role of the fruit fly Drosophila and nematode worms in biology, troops of baboons in primatology, box and digital simulations of the movement of the earth's crust in geology, and meteorological models in climatology. They analyze the intensive study of the prisoner's dilemma in game theory, ritual in anthropology, the individual case in psychoanalytic research, and Athenian democracy in political theory. The contributors illuminate the processes through which particular organisms, cases, materials, or narratives become foundational to their fields, and they examine how these foundational exemplars-from the fruit fly to Freud's Dora-shape the knowledge produced within their disciplines.

For much of the twentieth century scientists sought to explain objects and processes by reducing them to their components-nuclei into protons and neutrons, proteins into amino acids, and so on-but over the past forty years there has been a marked turn toward explaining phenomena by building them up rather than breaking them down. This collection reflects on the history and significance of this turn toward "growing explanations" from the bottom up. The essays show how this strategy-based on a widespread appreciation for complexity even in apparently simple processes and on the capacity of computers to simulate such complexity-has played out in a broad array of sciences. They describe how scientists are reordering knowledge to emphasize growth, change, and contingency and, in so doing, are revealing even phenomena long considered elementary-like particles and genes-as emergent properties of dynamic processes. Written by leading historians and philosophers of science, these essays examine the range of subjects, people, and goals involved in changing the character of scientific analysis over the last several decades. They highlight the alternatives that fields as diverse as string theory, fuzzy logic, artificial life, and immunology bring to the forms of explanation that have traditionally defined scientific modernity. A number of the essays deal with the mathematical and physical sciences, addressing concerns with hybridity and the materials of the everyday world. Other essays focus on the life sciences, where questions such as "What is life?" and "What is an organism?" are undergoing radical re-evaluation. Together these essays mark the contours of an ongoing revolution in scientific explanation. Contributors.
