Book Description
Early practitioners of the social studies of science turned their attention away from questions of institutionalization, which had tended to emphasize macrolevel explanations, and attended instead to microstudies of laboratory practice. Though sympathetic to this approach--as the microstudies included in this book attest--the author is interested in re-investigating certain aspects of institution formation, notably the formation of scientific, medical, and engineering disciplines. He emphasizes the manner in which science as cultural practice is imbricated with other forms of social, political, and even aesthetic practices. This book offers case studies that reexamine certain critical junctures in the traditional historical picture of the evolution of the role of the scientist in modern Western society. It focuses especially on the establishment of new disciplines within German research universities in the nineteenth century, the problematic relationship that emerged between science, industry, and the state at the turn of the twentieth century, and post-World War II developments in science and technology. After an Introduction and two chapters dealing with science and technology as cultural production and the struggles of disciplines to achieve legitimation and authority, the author considers the following topics: the organic physics of 1847; the innovative research program of Carl Ludwig as a model for institutionalizing science-based medicine; optics, painting, and ideology in Germany, 1845-95; Paul Ehrlich's "magic bullet"; the Haber-Bosch synthesis of ammonia; and the introduction of nuclear magnetic resonance instrumentation into the practice of organic chemistry.

Book Description
An understanding of the quantum mechanical nature of magnetism has led to the development of new magnetic materials which are used as permanent magnets, sensors, and information storage. Behind these practical applications lie a range of fundamental ideas, including symmetry breaking, order parameters, excitations, frustration, and reduced dimensionality. This superb new textbook presents a logical account of these ideas, staring from basic concepts in electromagnetsim and quantum mechanics. It outlines the origin of magnetic moments in atoms and how these moments can be affected by their local environment inside a crystal. The different types of interactions which can be present between magnetic moments are described. The final chapters of the book are devoted to the magnetic properties of metals, and to the complex behaviour which can occur when competing magnetic interactions are present and/or the system has a reduced dimensionality. Throughout the text, the theorectical principles are applied to real systems. There is substantial discussion of experimental techniques and current reserach topics. The book is copiously illustrated and contains detailed appendices which cover the fundamental principles.

Book Description
It has long been assumed that new product innovations are typically developed by product manufacturers, an assumption that has inevitably had a major impact on innovation-related research and activities ranging from how firms organize their research and development to how governments measure innovation. In this synthesis of his seminal research, von Hippel challenges that basic assumption and demonstrates that innovation occurs in different places in different industries. Presenting a series of studies showing that end-users, material suppliers, and others are the typical sources of innovation in some fields, von Hippel explores why this variation in the "functional" sources of innovation occurs and how it might be predicted. He also proposes and tests some implications of replacing a manufacturer-as-innovator assumption with a view of the innovation process as predictably distributed across users, manufacturers, and suppliers. Innovation, he argues, will take place where there is greatest economic benefit to the innovator.

Book Description
Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.

Book Description
A history of the origins and development of the American atomic bomb program during WWII. Begins with the scientific developments of the pre-war years. Details the role of the U.S. government in conducting a secret, nationwide enterprise that took science from the laboratory and into combat with an entirely new type of weapon. Concludes with a discussion of the immediate postwar period, the debate over the Atomic Energy Act of 1946, and the founding of the Atomic Energy Commission. Chapters: the Einstein letter; physics background, 1919-1939; early government support; the atomic bomb and American strategy; and the Manhattan district in peacetime. Illustrated.

Book Description
In this historical volume Salvatore Califano traces the developments of ideas and theories in physical and theoretical chemistry throughout the 20th century. This seldom-told narrative provides details of topics from thermodynamics to atomic structure, radioactivity and quantum chemistry. Califano’s expertise as a physical chemist allows him to judge the historical developments from the point of view of modern chemistry. This detailed and unique historical narrative is fascinating for chemists working in the fields of physical chemistry and is also a useful resource for science historians who will enjoy access to material not previously dealt with in a coherent way.
