Available in PDF, EPUB and Kindle. Book excerpt: Offering a comprehensive narrative of the early history of stereochemistry, Dr Ramberg explores the reasons for and the consequences of the fundamental change in the meaning of chemical formulas with the emergence of stereochemistry during the last quarter of the nineteenth century. As yet relatively unexplored by historians, the development of stereochemistry - the study of the three-dimensional properties of molecules - provides a superb case study for exploring the meaning and purpose of chemical formulas, as it entailed a significant change in the meaning of chemical formulas from the purely chemical conception of 'structure' to the physico-chemical conception of molecules provided by the tetrahedral carbon atom. This study is the first to treat the emergence of the unique visual language of organic chemistry between 1830 and 1874 to place in context the near simultaneous proposal of the tetrahedral carbon atom by J.H. van 't Hoff and J.A. Le Bel in 1874. Dr Ramberg then examines the research programs in stereochemistry by Johannes Wislicenus, Arthur Hantzsch, Victor Meyer, Carl Bischoff, Emil Fischer and Alfred Werner, showing how the emergence of stereochemistry was a logical continuation of established research traditions in chemistry. In so doing, he also illustrates the novel and controversial characteristics of stereochemical ideas, especially the unprecedented use of mechanistic and dynamic principles in chemical explanation.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide a synthesis of the history, generation, use, and transfer of images in scientific practice. It delves into the rich reservoir of case studies on visual representations in scientific and technological practice that have accumulated over the past couple of decades by historians, sociologists, and philosophers of science. The main aim is thus located on the meta-level. It adopts an integrative view of recurrently noted general features of visual cultures in science and technology, something hitherto unachieved and believed by many to be a mission impossible. By systematic comparison of numerous case studies, the purview broadens away from myopic microanalysis in search of overriding patterns. The many different disciplines and research areas involved encompass mathematics, technology, natural history, medicine, the geosciences, astronomy, chemistry, and physics. The chosen examples span the period from the Renaissance to the late 20th century. The broad range of visual representations in scientific practice is treated, as well as schooling in pattern recognition, design and implementation of visual devices, and a narrowing in on the special role of illustrators and image specialists.

This book was released on 2013-04-17 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: constitutive of reference in laboratory sciences as cultural sign systems and their manipulation and superposition, collectively shared classifications and associated conceptual frameworks,· and various fonns of collective action and social institutions. This raises the question of how much modes of representation, and specific types of sign systems mobilized to construct them, contribute to reference. Semioticians have argued that sign systems are not merely passive media for expressing preconceived ideas but actively contribute to meaning. Sign systems are culturally loaded with meaning stemming from previous practical applications and social traditions of applications. In new local contexts of application they not only transfer stabilized meaning but also can be used as active resources to add new significance and modify previous meaning. This view is supported by several analyses presented in this volume. Sign systems can be implemented like tools that are manipulated and superposed with other types of signs to forge new representations. The mode of representation, made possible by applying and manipulating specific types of representational tools, such as diagrammatic rather than mathematical representations, or Berzelian fonnulas rather than verbal language, contributes to meaning and forges fine-grained differentiations between scientists' concepts. Taken together, the essays contained in this volume give us a multifaceted picture of the broad variety of modes of representation in nineteenth-century and twentieth-century laboratory sciences, of the way scientists juxtaposed and integrated various representations, and of their pragmatic use as tools in scientific and industrial practice.
Download or read book The Construction of Analogy Based Research Programs written by Rebecca Mertens and published by transcript Verlag. This book was released on 2019-04-30 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the German chemist Emil Fischer presented his lock-and-key hypothesis in 1899, his analogy to describe the molecular relationship between enzymes and substrates quickly gained vast influence and provided future generations of scientists with a tool to investigate the relation between chemical structure and biological specificity. Rebecca Mertens explains the appeal of the lock-and-key analogy by its role in model building and in the construction of long-term, cross-generational research programs. She argues that a crucial feature of these research programs, namely ascertaining the continuity of core ideas and concepts, is provided by a certain way of analogy-based modelling.
Download or read book A Cultural History of Chemistry in the Nineteenth Century written by Peter J. Ramberg and published by Bloomsbury Publishing. This book was released on 2023-12-14 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Cultural History of Chemistry in the Nineteenth Century covers the period from 1815 to 1914 and the birth of modern chemistry. The elaboration of atomic theory - and new ideas of periodicity, structure, bonding, and equilibrium - emerged in tandem with new instruments and practices. The chemical industry expanded exponentially, fuelled by an increasing demand for steel, aluminium, dyestuffs, pharmaceuticals, and consumer goods. And the chemical laboratory became established in its two distinct modern settings of the university and industry. At the turn of the century, the discovery of radioactivity took hold of the public imagination, drawing chemistry closer to physics, even as it threatened to undermine the whole concept of atomism. The 6 volume set of the Cultural History of Chemistry presents the first comprehensive history from the Bronze Age to today, covering all forms and aspects of chemistry and its ever-changing social context. The themes covered in each volume are theory and concepts; practice and experiment; laboratories and technology; culture and science; society and environment; trade and industry; learning and institutions; art and representation. Peter J. Ramberg is Professor of the History of Science at Truman State University, USA. Volume 5 in the Cultural History of Chemistry set. General Editors: Peter J. T. Morris, University College London, UK, and Alan Rocke, Case Western Reserve University, USA.

Download or read book A History of Folding in Mathematics written by Michael Friedman and published by Birkhäuser. This book was released on 2018-05-25 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: While it is well known that the Delian problems are impossible to solve with a straightedge and compass – for example, it is impossible to construct a segment whose length is cube root of 2 with these instruments – the discovery of the Italian mathematician Margherita Beloch Piazzolla in 1934 that one can in fact construct a segment of length cube root of 2 with a single paper fold was completely ignored (till the end of the 1980s). This comes as no surprise, since with few exceptions paper folding was seldom considered as a mathematical practice, let alone as a mathematical procedure of inference or proof that could prompt novel mathematical discoveries. A few questions immediately arise: Why did paper folding become a non-instrument? What caused the marginalisation of this technique? And how was the mathematical knowledge, which was nevertheless transmitted and prompted by paper folding, later treated and conceptualised? Aiming to answer these questions, this volume provides, for the first time, an extensive historical study on the history of folding in mathematics, spanning from the 16th century to the 20th century, and offers a general study on the ways mathematical knowledge is marginalised, disappears, is ignored or becomes obsolete. In doing so, it makes a valuable contribution to the field of history and philosophy of science, particularly the history and philosophy of mathematics and is highly recommended for anyone interested in these topics.
Download or read book Methods and Styles in the Development of Chemistry written by Joseph Stewart Fruton and published by American Philosophical Society. This book was released on 2002 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry as it is known today is deeply rooted in a variety of thought & action, dating back at least as far as the fifth century B.C. In this book, Joseph Fruton weaves together the history of scientific investigation with social, religious, philosophical, & other events & practices that have contributed to the field of modern chemistry. The story begins with the influence of alchemy on early Greek numerology and philosophy, followed by the historical account of chemical composition and phlogiston. The life and work of Antoine Lavoisier receive extensive coverage in Chapter Three, with the remaining six chapters devoted to atoms, equivalents, and elements; radicals and types; valence and molectualr structure; stereochemistry and organic synthesis; forces, equilibria, and rates; and electrons, reaction mechanisms, and organic synthesis.

Download or read book Image and Reality written by Alan J. Rocke and published by University of Chicago Press. This book was released on 2010-05-15 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nineteenth-century chemists were faced with a particular problem: how to depict the atoms and molecules that are beyond the direct reach of our bodily senses. In visualizing this microworld, these scientists were the first to move beyond high-level philosophical speculations regarding the unseen. In Image and Reality, Alan Rocke focuses on the community of organic chemists in Germany to provide the basis for a fuller understanding of the nature of scientific creativity. Arguing that visual mental images regularly assisted many of these scientists in thinking through old problems and new possibilities, Rocke uses a variety of sources, including private correspondence, diagrams and illustrations, scientific papers, and public statements, to investigate their ability to not only imagine the invisibly tiny atoms and molecules upon which they operated daily, but to build detailed and empirically based pictures of how all of the atoms in complicated molecules were interconnected. These portrayals of “chemical structures,” both as mental images and as paper tools, gradually became an accepted part of science during these years and are now regarded as one of the central defining features of chemistry. In telling this fascinating story in a manner accessible to the lay reader, Rocke also suggests that imagistic thinking is often at the heart of creative thinking in all fields. Image and Reality is the first book in the Synthesis series, a series in the history of chemistry, broadly construed, edited by Angela N. H. Creager, John E. Lesch, Stuart W. Leslie, Lawrence M. Principe, Alan Rocke, E.C. Spary, and Audra J. Wolfe, in partnership with the Chemical Heritage Foundation.
