In The Mangle of Practice (1995), the renowned sociologist of science Andrew Pickering argued for a reconceptualization of research practice as a “mangle,” an open-ended, evolutionary, and performative interplay of human and non-human agency. While Pickering’s ideas originated in science and technology studies, this collection aims to extend the mangle’s reach by exploring its application across a wide range of fields including history, philosophy, sociology, geography, environmental studies, literary theory, biophysics, and software engineering.

The Mangle in Practice opens with a fresh introduction to the mangle by Pickering. Several contributors then present empirical studies that demonstrate the mangle’s applicability to topics as diverse as pig farming, Chinese medicine, economic theory, and domestic-violence policing. Other contributors offer examples of the mangle in action: real-world practices that implement a self-consciously “mangle-ish” stance in environmental management and software development. Further essays discuss the mangle as philosophy and social theory. As Pickering argues in the preface, the mangle points to a shift in interpretive sensibilities that makes visible a world of de-centered becoming. This volume demonstrates the viability, coherence, and promise of such a shift, not only in science and technology studies, but in the social sciences and humanities more generally.

This ambitious book by one of the most original and provocative thinkers in science studies offers a sophisticated new understanding of the nature of scientific, mathematical, and engineering practice and the production of scientific knowledge.

Andrew Pickering offers a new approach to the unpredictable nature of change in science, taking into account the extraordinary number of factors—social, technological, conceptual, and natural—that interact to affect the creation of scientific knowledge. In his view, machines, instruments, facts, theories, conceptual and mathematical structures, disciplined practices, and human beings are in constantly shifting relationships with one another—"mangled" together in unforeseeable ways that are shaped by the contingencies of culture, time, and place.

Situating material as well as human agency in their larger cultural context, Pickering uses case studies to show how this picture of the open, changeable nature of science advances a richer understanding of scientific work both past and present. Pickering examines in detail the building of the bubble chamber in particle physics, the search for the quark, the construction of the quarternion system in mathematics, and the introduction of computer-controlled machine tools in industry. He uses these examples to address the most basic elements of scientific practice—the development of experimental apparatus, the production of facts, the development of theory, and the interrelation of machines and social organization.
