Available in PDF, EPUB and Kindle. Book excerpt: This study focuses on the French chemists of 1830-1858, and their roles in the development of organic chemistry and its eventual connectin with atomic and valence-bond theory, and uncovers new complexities in the thought processes that led to the concept of valence. The exploration of Laurent's early career reveals that this French chemist had proposed a hyposthesis to explain phenomena due to valence fifteen years before August Kekule's Exposition of the classic valence-bond theory in 1858. Laurent put forward a hypothesis supposing the dividibility of atoms at a time when such a theory was far removed from the possiblity of experimentation. Within the positivist philosophy which prevailed at the time, few besides him would have dared to advance such a hypothesis. Laurent's hypothesis influenced certain advances in his chemistry, and that of his close associate, Charles Gerhardt, and eventually these advances helped turn most chemists to atomism.

Download or read book Philosophical Chemistry written by Manuel DeLanda and published by Bloomsbury Publishing. This book was released on 2015-05-21 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Philosophical Chemistry furthers Manuel DeLanda's revolutionary intervention in the philosophy of science and science studies. Against a monadic and totalizing understanding of science, DeLanda's historicizing investigation traces the centrality of divergence, specialization and hybridization through the fields and subfields of chemistry. The strategy followed uses a series of chemical textbooks, separated from each other by fifty year periods (1750, 1800, 1850, and 1900), to follow the historical formation of consensus practices. The three chapters deal with one subfield of chemistry in the century in which it was developed: eighteenth-century inorganic chemistry, nineteenth-century organic chemistry, and nineteenth-century physical chemistry. This book creates a model of a scientific field capable of accommodating the variation and differentiation evident in the history of scientific practice. DeLanda proposes a model that is made of three components: a domain of phenomena, a community of practitioners, and a set of instruments and techniques connecting the community to the domain. Philosophical Chemistry will be essential reading for those engaged in emergent, radical and contemporary strands of thought in the philosophy of science and for those scholars and students who strive to practice a productive dialogue between the two disciplines.
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 Molecular World written by Catherine M. Jackson and published by MIT Press. This book was released on 2023-07-04 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compelling and innovative account that reshapes our view of nineteenth-century chemistry, explaining a critical period in chemistry’s quest to understand and manipulate organic nature. According to existing histories, theory drove chemistry’s remarkable nineteenth-century development. In Molecular World, Catherine M. Jackson shows instead how novel experimental approaches combined with what she calls “laboratory reasoning” enabled chemists to bridge wet chemistry and abstract concepts and, in so doing, create the molecular world. Jackson introduces a series of practice-based breakthroughs that include chemistry’s move into lampworked glassware, the field’s turn to synthesis and subsequent struggles to characterize and differentiate the products of synthesis, and the gradual development of institutional chemical laboratories, an advance accelerated by synthesis and the dangers it introduced. Jackson’s historical reassessment emerges from the investigation of alkaloids by German chemists Justus Liebig, August Wilhelm Hofmann, and Albert Ladenburg. Stymied in his own research, Liebig steered his student Hofmann into pioneering synthesis as a new investigative method. Hofmann’s practice-based laboratory reasoning produced a major theoretical advance, but he failed to make alkaloids. That landmark fell to Ladenburg, who turned to cutting-edge theory only after his successful synthesis. In telling the story of these scientists and their peers, Jackson reveals organic synthesis as the ground chemists stood upon to forge a new relationship between experiment and theory—with far-reaching consequences for chemistry as a discipline.
Download or read book Nationalizing Science written by Alan J. Rocke and published by MIT Press. This book was released on 2000-11-08 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: After looking at the early careers of Wurtz's two mentors, Liebig and Jean-Baptiste Dumas, Rocke describes Wurtz's life and career in the politically complex period leading up to 1853. He then discusses the turning point in Wurtz's intellectual life—his conversion to the "reformed chemistry" of Laurent, Gerhardt, and Williamson—and his efforts to persuade his colleagues of the advantages of the new system. In 1869, Adolphe Wurtz (1817-1884) called chemistry "a French science." In fact, however, Wurtz was the most internationalist of French chemists. Born in Strasbourg and educated partly in the laboratory of the great Justus Liebig, he spent his career in Paris, where he devoted himself to introducing German ideas into French scientific circles. His life therefore provides an excellent vehicle for considering the divergent trajectories of French and German chemistry—and, by extension, French and German science—during this crucial period. After looking at the early careers of Wurtz's two mentors, Liebig and Jean-Baptiste Dumas, Rocke describes Wurtz's life and career in the politically complex period leading up to 1853. He then discusses the turning point in Wurtz's intellectual life—his conversion to the "reformed chemistry" of Laurent, Gerhardt, and Williamson—and his efforts (social and political, as well as scientific) to persuade his colleagues of the advantages of the new system. He looks at political patronage, or the lack thereof, and at the insufficient material support from the French government, during the middle decades of the century. From there Rocke goes on to examine the rivalry between Wurtz and Marcellin Berthelot, the debate over atoms versus equivalents, and the reasons for Wurtz's failure to win acceptance for his ideas. The story offers insights into the changing status of science in this period, and helps to explain the eventual course of both French and German chemistry.

Download or read book Experiments Models Paper Tools written by Ursula Klein and published by Stanford University Press. This book was released on 2003 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early nineteenth century, chemistry emerged in Europe as a truly experimental discipline. What set this process in motion, and how did it evolve? Experimentalization in chemistry was driven by a seemingly innocuous tool: the sign system of chemical formulas invented by the Swedish chemist Jacob Berzelius. By tracing the history of this “paper tool,” the author reveals how chemistry quickly lost its orientation to natural history and became a major productive force in industrial society. These formulas were not merely a convenient shorthand, but productive tools for creating order amid the chaos of early nineteenth-century organic chemistry. With these formulas, chemists could create a multifaceted world on paper, which they then correlated with experiments and the traces produced in test tubes and flasks. The author’s semiotic approach to the formulas allows her to show in detail how their particular semantic and representational qualities made them especially useful as paper tools for productive application.
