    Ursula Klein (2012). Objects of Inquiry in Classical Chemistry: Material Substances. [REVIEW] Foundations of Chemistry 14 (1):7-23.
    I argue in the paper that classical chemistry is a science predominantly concerned with material substances, both useful materials and pure chemical substances restricted to scientific laboratory studies. The central epistemological and methodological status of material substances corresponds with the material productivity of classical chemistry and its way of producing experimental traces. I further argue that chemist’s ‘pure substances’ have a history, conceptually and materially, and I follow their conceptual history from the Paracelsian concept of purity to the modern concept (...)

    U. Klein (2003). Experimental History and Herman Boerhaave's Chemistry of Plants. Studies in History and Philosophy of Science Part C 34 (4):533-567.
    In the early eighteenth century, chemistry became the main academic locus where, in Francis Bacon's words, Experimenta lucifera were performed alongside Experimenta fructifera and where natural philosophy was coupled with natural history and 'experimental history' in the Baconian and Boyleian sense of an inventory and exploration of the extant operations of the arts and crafts. The Dutch social and political system and the institutional setting of the university of Leiden endorsed this empiricist, utilitarian orientation toward the sciences, which was forcefully (...)

    U. Klein (2001). Paper Tools in Experimental Cultures. Studies in History and Philosophy of Science Part A 32 (2):265-302.
    The paper studies various functions of Berzelian formulas in European organic chemistry prior to the mid-nineteenth century from a semiotic, historical and epistemological perspective. I argue that chemists applied Berzelian formulas as productive 'paper tools' for creating a chemical order in the 'jungle' of organic chemistry. Beginning in the late 1820s, chemists applied chemical formulas to build models of the binary constitution of organic compounds in analogy to inorganic compounds. Based on these formula models, they constructed new classifications of organic (...)

    The paper examines differences of styles of experimentation in the history of science. It presents arguments for a historization of our historial and philosophical notion of "experimentation," which question the common view that "experimental philosophy" was the only style of experimentation in the eighteenth and early nineteenth centuries. It argues, in particular, that "experimental history" and technological inquiry were accepted styles of academic experimentation at the time. These arguments are corroborated by a careful analysis of a case study, which is (...)

    A quantization procedure without Hamiltonian is reported which starts from a statistical ensemble of particles of mass m and an associated continuity equation. The basic variables of this theory are a probability density ρ, and a scalar field S which defines a probability current j=ρ ∇ S/m. A first equation for ρ and S is given by the continuity equation. We further assume that this system may be described by a linear differential equation for a complex-valued state variable χ. Using (...)

    I argue and demonstrate in this essay that interconnected systems of science and technology, or technoscience, existed long before the late nineteenth century, and that eighteenth-century chemistry was such an early form of technoscience. Based on recent historical research on the early development of carbon chemistry from the late 1820s until the 1840s—which revealed that early carbon chemistry was an experimental expert culture that was largely detached from the mundane industrial world—I further examine the question of the internal preconditions within (...)

    This paper studies the semiotic,epistemological and historical aspects of Berzelianformulas in early nineteenth-century organicchemistry. I argue that Berzelian formulas wereenormously productive `paper tools' for representingchemical reactions of organic substances, and forcreating different pathways of reactions. Moreover, myanalysis of Jean Dumas's application of Berzelianformulas to model the creation of chloral from alcoholand chlorine exemplifies the role played by chemicalformulas in conceptual development (the concept ofsubstitution). Studying the dialectic of chemists'collectively shared goals and tools, I argue thatpaper tools, like laboratory instruments, areresources (...)

    This paper studies European chemists’ shifting ontologies of materials by comparing the ways in which they classified materials. The focus is on plant materials, their different identities, and the changing ways chemists sorted out and ordered plant materials in the eighteenth and early nineteenth centuries. The main goals of the paper are to follow the development of plant materials from ordinary, everyday materials and commodities in the early eighteenth century to purified carbon compounds and organic substances familiar only to experts (...)

    This paper discusses stress patterns concerning the relation between intonation and the meaning of an utterance. It is argued that this should be done within a linguistic approach. While the first part of this paper deals with differences in meaning that are caused by differences in intonation, the second part gives an overview over the focus theories of Hohle, Rochemont, and Jacobs. Within this discussion the interrelation is shown between the syntactic feature (+F) (+focus) and the phonetic and semantic properties (...)

    E.F. Geoffroy's table of different relations ( rapports ) between different chemical substances is mainly based on empirical knowledge accumulated in 16th and 17th century metallurgy and pharmacy. The substances listed in the left half of the table were basic for the formation of salts which were produced for medical ends in the chemical-pharmaceutical practice of the 17th century. The right half of the table refers to substances and operations of metallurgy which had already been described in the metallurgical writings (...)

He visited mines, inspected smelting works, calculated budgets, wrote official reports, founded a mining school, performed technological experiments, and invented a miners? lamp and respirator. At the same time he also participated in the Republic of Letters, corresponded with savants in all Europe, and was a member of the Leopoldine Carolinian Academy and the Berlin Gesellschaft Naturforschender Freunde. He collected minerals, (...)

    As an adolescent and young adult who defined herself as a bookworm and aspiring scholar, I was hardly interested in sports growing up. Though outgoing and extroverted, I enjoyed creative pursuits such as writing fiction, playing the piano, and performing on stage in school theatricals and shied away from sports. As a child, I enjoyed riding my bike, roller skating, climbing trees, or sprinting short distances over the playground, but, at school, I was not adept at team sports. I was (...)

Members of the physical and mathematical classes of the Royal Prussian Academy of Sciences were involved in State projects such as surveying for the construction of canals, chemical analysis of Silesian iron, production of porcelain and of beet sugar. Some of these men were truly ?hybrid? experts living both in the worlds of State-directed manufacture and academic natural (...)
