Book Description
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.

Book Description
Scientists often try to understand the world by building simplified and idealised models of it. Adam Toon develops a new approach to scientific models by comparing them to the dolls and toy trucks of children's imaginative games, and offers a unified framework to solve difficult metaphysical problems and help to make sense of scientific practice.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
"This is one of the most important studies of nineteenth century chemistry produced during the past two decades. Building on his equally important earlier book . . . this work will establish Rocke as the leading scholar in this field."--Frederic L. Holmes, Yale University "With this work, Rocke has become the leading authority on German chemistry in the first two-thirds of the nineteenth century."--Kathryn M. Olesko, Georgetown University
