This paper reports the experience of reconstructing a surveying instrument—the plane table—using the description found in Arthur Hopton’s Speculum topographicum: or The topographicall glasse : ‘Of the Plaine Table, with a description thereof, and the parts thereunto belonging’. One of the most detailed early printed descriptions of the instrument, it is illustrated with woodcut diagrams of components but no image of the complete plane table. The reconstruction process did not prove entirely straightforward. An examination of its various stages reveals how (...) Hopton’s text set out to persuade and lead the reader, rather than issuing orders to be followed exactly; the reader, left to make some decisions himself, would thus create a plane table with an element of uniqueness in its character. The role of the maker of such an instrument, even when following written instructions, was a creative and collaborative one, rather than purely passive.Keywords: Reconstruction; Instrument; Diagrams; Text; Instrument-maker; Collaboration.

The historic scientific collections of well-established University Museums—the Whipple at Cambridge and the Museum of the History of Science at Oxford, for example—have long served in university teaching and as objects of research for historians. But what is involved in starting such a museum from scratch? This paper offers some reflections based on recent experiences at the University of Leeds. In a relatively short period, the Leeds project has grown from a small volunteer initiative, aimed at salvaging disparate scientific collections (...) from all over the campus, to a centrally supported and long-term scheme to provide collections care, exhibitions, and public events, as well as material for teaching and research within history and philosophy of science. Recent work undertaken on a range of Leeds objects and collections, including a camera reportedly used to take the first X-ray diffraction photographs of DNA in the 1930s and the Mark 1 prototype of the MONIAC, built and designed at Leeds in 1949 to model the flow of money through the economy, highlights the national and international significance of the University’s scientific heritage as well as the project’s ambition of providing students with on-going collections care responsibilities and object-research experience. Sketching possible futures for the Leeds project, the paper considers challenges confronting the heritage sector more broadly, and how those involved with historic scientific collections can make use of new opportunities for teaching, research, and public engagement.

Historians have usually connected the presentation of nature as a part of natural history with the natural cabinet or the natural history museum. A closer look at travel and field work, however, shows that display of nature as a spatial concept and set of material conditions begins already in the first moment of collecting objects, specimens and economic information about a region. In 1720 Tsar Peter I of Russia sent the German physician Daniel Gottlieb Messerschmidt to Siberia to explore this (...) hitherto terra incognita. During his travels Messerschmidt established two main instruments for collecting data and things, which I shall describe as organizing, material principles for his field work: written lists and notes, and boxes and cases. An analysis of these material objects and their specific uses reveals the intellectual and practical traditions in which learned activities and strategies took place at the beginning of the eighteenth century.

With the interest in studying science as practice came an interest in the material artefacts and things that form part of scientific activities in the laboratory, the field, the classroom, or the political arena. This shift in interest in connection with new modes of knowledge production raises new questions regarding the “archive” of science: what should be preserved and where to make it possible to reconstruct scientific practices in the desired detail? While digital media may be able to bridge some (...) of the traditional divisions between the collection of scientific artefacts in museums and the written archival depositories, the move to performing science in silico produces new challenges in respect to establishing the material archives of current science. The paper will discuss these and related questions with special reference to the archives of the contemporary life sciences. (shrink)

Scientists, their allies, and opponents engage in struggles not just over what is true, but who may validate, access, and engage contentious knowledge. Viewed through the metaphor of theater, science is always performed for an audience, and that audience is constructed strategically and with consequence. Insights from theater studies, the public understanding of science, and literature on boundary work and framing contribute to a proposal for a framework to explore the construction of audiences during scientific controversy, consisting of three parameters: (...) history, composition, and role. Applying this framework to the controversy over the presence of genetically modified maize in Mexico demonstrates how multiple and contested audiences form during a scientific controversy. Different scientific ?productions? construct distinct or overlapping audiences; audiences constructed at one time become ?easy recruits? for later stages of the controversy; and the various roles cast for different audiences showcase strategies for building scientific power and reflect assumptions about the capacity for publics to participate in the governance and production of science.

Faraday demonstrated electromagnetic induction in 1831 using an iron ring wound with two wire coils; on interrupting battery current in one coil, momentary currents arose in the other. Between Faraday's ring and the induction coil, coiled instruments developed via meandering paths. This paper explores the opening phase of that work in the late 1830s, as the iron core, primary wire coil, and secondary wire coil were researched and differentiated. ‘Working knowledge’ gained with materials and phenomena was crucial to innovations. To (...) understand these material-based interactions, I experimented with hand-wound coils, along with examining historical texts, drawings, and artefacts. My experience recovered the historical dead-end of two-wire coils and ensuing work with long-coiled single conductors initiated by Faraday and Henry. The shock and spark heightened in these coils provided feedback to the many instrumental configurations tested by Page, Callan, Sturgeon, Bachhoffner, and others. The continuous conductor differentiated into two segments soldered together: a thick short wire carrying battery current and a long thin wire for elevating shocks . The joined wires eventually separated, yet their transitional connection documents belief that the induced effects depend on continuity. These coiled instruments, with their intertwined histories, show experimental work and understandings in the process of developing. Seeing the nonlinear paths by which these instruments developed deepens our understanding of historical experiences, and of how people learn. (shrink)

History of science provides access to a reservoir of meaningful experiments that can be studied and reproduced in classrooms. This is the case of Joule’s paddle-wheel experiment which displays the potentiality to help students improve their understanding of the concept of energy. This experiment has been mentioned in many physics textbooks during the twentieth century. Recently, it has received renewed attention by several researchers in science education. However, the accounts of Joule’s experiment proposed by these researchers are at variance with (...) each other: either in terms of equivalences, in terms of energy change, or in terms of energy transformation and Rankine’s definition. This raises several questions: What is their respective contribution to the understanding of the historical emergence of the energy concept, and to the understanding of the very meaning of this concept? Are these accounts concurrent? Eventually, how can they help for the teaching energy? To investigate these questions, historical details concerning this experiment are first considered. It is stressed that Joule did not made use of the concept of energy, and instead described his experiment in terms of conversion of living force into heat. The three accounts of Joule’s experiment are then presented and their respective contribution discussed. By emphasizing different aspects of this experiment, they are shown to suggest different strategies for teaching energy. For all that, they are not contradictory and, considered together, they bring to light the great potential of Joule’s experiment to foster students understanding of this concept. (shrink)

Perfumes embody a chemical record of style and technology. Blurring the boundary between what counts as natural and artificial in both a material and a perceptual sense, perfumery presents us with a domain of multiple disciplinary identities relevant to social studies: art, craft, and techno‐science. Despite its profound impact as a cultural practice, perfume has seldom featured in historical scholarship. The reason for this neglect is its inherently qualitative dimension: perfume cannot be understood via codified representation but requires direct acquaintance (...) with its sensory and material basis. The historical study of perfumery thus necessitates an experimental approach that comes not without challenge. This article looks at contemporary recreations of old perfumes to identify the difficulties involved in the experimental recreation of fragrances as sensory and performative artifacts. We highlight the need for a reconceptualization of methodology for inconcrete objects of study as part of the broader interest in experimental approaches to the humanities. (shrink)

ABSTRACT Beginning with the meaning and use of the word “performance,” this essay analyzes some of the ambiguities and tensions performance has historically engendered. These tensions were both social and epistemic and can be sketched out with relation to either the corrupting influences of performance as dissimulation and masquerade or its didactic possibilities as exemplary of morality, virtue, and truth. Following these tensions across the history of antitheatrical literature into early modern natural philosophy, the essay attempts to show some of (...) the ways that natural philosophy was used to perform—regulate, discipline, and direct—its audience(s), while simultaneously being itself performed—through interlocking practices enacted by sites, objects, and humans—as demonstrative of the legitimacy of its social and epistemic authority.

Despite the vast amount of work produced by philosophers, historians and sociologists on the nature of scientific activity, “observation itself is rarely the focus of attention and almost never the subject of historical inquiry in its own right”. This general lack of interest in the nature of scientific observation was perhaps most clearly reflected in the Vienna Circle’s attempt to establish an analysis of science beginning at the level of protocol sentences. To do so, of course, they had to disregard (...) the humidity and fogged lenses facing the primatologist in the jungle, or the way in which flights aboard military aircraft were once sought by physicists in order to expose...

James Prescott Joule’s (1818–1889) bicentenary took place in 2018 and commemorated by the IDTC with a Symposium—‘James Joule’s Bicentenary: Scientific and Pedagogical Issues Concerning Energy Conservation’—at the European Society for the History of Science (ESHS & BSHS), 14th–17th September, 2018, in London. This symposium had three main objectives: It aimed specifically to celebrate James Joule’s achievements considering the most recent historiographical works with a particular focus on the principle of conservation of energy; It served the purpose of discussing the scientific (...) and pedagogical issues related to heat, energy and work and how they are presented in textbooks and worked out in classrooms; It also provided discussions on the present situation of teaching and learning science through the use of History of Science, both in K-12 and college level with an emphasis on energy and related concepts. In the following, the Introduction of this Special Issue on Joule is presented. (shrink)

In this article, Thomas Kuhn’s theory of incommensurable paradigms learned through exemplars is discussed as a theory of acculturation akin to those of cultural anthropology. Yet his hermeneutic approach results in a classic problem, referred to here as the paradox of objective relativism. A solution, at least for observers of contemporary cultures, is drawn from Kuhn’s own writings: a fieldwork method of “going native.” It is argued that Kuhn’s views are as important a corrective for anthropologists studying native systems of (...) knowledge as they have been for philosophers and sociologists of science. The epistemological and disciplinary implications of such a methodology are discussed. (shrink)

In this paper I discuss a cardboard dissected globe made in 1813 by Edward Mogg, a cartographer and map seller, to instruct children in the principles of astronomy. Since little is known about the maker or the specific object, I draw on evidence beyond the sphere itself to construct an account of how the object might have been used. In particular I address conversation as a key part of astronomical education and examine the way in which the cardboard plates of (...) the sphere, the presentation slipcase and the accompanying booklet would have prepared young learners for polite astronomical discourse around large instruments in later life.Keywords: Dissected globe; Edward Mogg; Educational toys; Astronomy; Conversation.

This paper deals with calibration in scientific practices which investigate relatively well-understood natural phenomena by means of already standardized instrumental devices. Calibration is a crucial topic, since it conditions the reliability of instrumental procedures in science. Yet although important, calibration is a relatively neglected topic. We think more attention should be devoted to calibration. The paper attempts to take a step in this direction. The aims are two-fold: (1) to characterize calibration in a relatively simple kind of scientific practices; (2) (...) to provide conceptual and taxonomic tools of broader scope that help to get a better understanding of calibration in more complex cases and other kinds of scientific practices. For this purpose, we first provide indications for why a conceptual framework is needed. Second, a bibliographic survey of works dealing with calibration is attempted. Third, we introduce different tools to enable a better understanding of calibration. Fourth, we turn to the elaboration of what we call a “simple exemplar” of calibration, illustrated through the case of the calibration of an equal-arm balance. Fifth, the tools previously introduced, and the framework of the simple exemplar, are applied to a more complex case of calibration: calibration procedures in X-ray experiments. This serves to show the work accomplished by the simple exemplar and to emphasize features of more complex cases of calibration. Eventually, we revisit and specify the nature, status, scope and value of the proposed framework. (shrink)

To analyze science as practice and culture has become, since the early 1970s, the object of the new history and sociology of science. Hence, historians and sociologists pay now more attention to the role of experiment in science. In order to study experiments we need to think more carefully about instruments, apparatus and their use. In this article I put forward a method which allows to do both, to study the materiality of experiment as well as the activities involved in (...) the production of experimental results: The replication of an experiment, ie. the reworking of historical experiments with a replica as close to the original as possible. A study of the experiments jointly done by James Joule, and William Thomson in 1852 will demonstrate what might be learned by this method about an experiment. The origins of instruments and the apparatus used in these experiments, their historical context and use will be discussed in detail. With the help of this case study I will try to show that the replication of experiments has much to contribute to an enhanced understanding of experimental practices. (shrink)

Tobacco mosaic virus has served as a model organism for pathbreaking work in plant pathology, virology, biochemistry and applied genetics for more than a century. We were intrigued by a photograph published in Phytopathology in 1934 showing that Tabasco pepper plants responded to TMV infection with localized necrotic lesions, followed by abscission of the inoculated leaves. This dramatic outcome of a biological response to infection observed by Francis O. Holmes, a virologist at the Rockefeller Institute for Medical Research, was used (...) to score plants for resistance to TMV infection. Our objective was to gain a better understanding of early to mid-twentieth century ideas of genetic resistance to viruses in crop plants. We investigated Holmes’ observation as a practical exercise in reworking an experiment, having been inspired by Pamela Smith’s innovative Making and Knowing Project. We had a great deal of difficulty replicating Holmes’ experiment, finding that biological materials and experimental customs change over time, in ways that ideas do not. Using complementary tools plus careful study and interpretation of the original text and figures, we were able to rework, yet only partially replicate, this experiment. Reading peer-reviewed manuscripts that cited Holmes’ 1934 report provided an additional level of insight into the interpretation and replication of this work in the decades that followed. From this, we touch on how experimental reworking can inform our strategies to address the reproducibility “crisis” in twenty-first century science. (shrink)

Works in science and technology studies have repeatedly pointed to the importance of the visual in scientific practice. STS has also explicated how embodied practice generates scientific knowledge. I aim to supplement this literature by pointing out how sound and hearing are integral aspects of experimentation. Sound helps define how and when lab work is done, and in what kinds of spaces. It structures experimental experience. It affords interactions between researchers and instruments that are richer than could be obtained with (...) vision alone. And it is a site for tacit knowledge, providing a resource for the replication of results, and the transmission of knowledge, and the construction of social boundaries within instrumental communities.

The focus of this paper is one of James Prescott Joule’s scientific contributions: the laws of heat production by electric currents in conductors. In 1841, the 22 years old Joule published a paper with the title “On the heat evolved by metallic conductors of electricity, and in the cells of a battery during electrolysis” where he presented an experimental study of that phenomenon and proposed two laws that were allegedly supported by his trials. On closer inspection, both his laboratory work (...) and his inferences can be challenged. The emphasis of this article is an attempt to understand Joule’s experimental undertaking, its highpoints and shortcomings, by a detailed analysis of this specific episode and by studying the precedents of his work and subsequent advancements. It is possible to point out several serious deficiencies of that investigation, and Joule’s contemporaries, such as Edmond Becquerel and Heinrich Lenz, did criticize some of his flaws and undertook new experiments to provide a sound basis for those laws. Besides providing a historical examination of that specific episode, this article uses this case study to tackle some features of the nature of science that may contribute to scientific education.

Starting from the seminal experience of James Prescott Joule, this paper aims to debate the possibility of “making” science outside universities and academies. Joule himself studied as an autodidact and did not make his own discoveries while following an academic path; on the contrary, at first, the associations and academic societies of the time tended not to recognize his works officially. All of this happened throughout the nineteenth century during the period of the first relevant tendency to science popularization. For (...) example, looking at the second half of the England of the 1800s, we can refer to Michael Faraday’s open lessons for children like The Chemical History of a Candle. Following this perspective from a historical view, this paper explores the Italian attempts to communicate science—from the ‘50s to the ‘70s—to a larger public via television and other media, also considering the political and social backgrounds behind this choice. In particular, this paper also deals with Lucio Lombardo Radice’s work on TV programs and writings in social-political journals and daily newspapers, as a mathematician and pedagogist engaged on the importance of what he specifically called “Scientific mediation”, as a “method” to teach and popularize science to a larger public.

Exactitude. The Genesis of an Epistemic Virtue in the ‘Long Nineteenth Century’. The article examines the genesis of exactitude as an epistemic virtue in both scholarly and scientific contexts in the 19th century, mainly in Prussia. Starting with an influential historiographic work on ancient metrology three semantic fields of accuracy, exactitude and precision are differentiated and pursued in their etymologies as well as applications. The historic situation between 1790 and 1860 is identified as the crucial period when the exactness of (...) the exact sciences as well as the notion of accuracy in the humanities start to diverge from one another in order to develop an epistemic virtue each on its own.

This article is a contribution to the history of the Geiger-Müller counter, based on the replication method. Along with a historical analysis of the Geiger-Müller counter I present and discuss my experience with replicas of early counters from 1928. The explicit and tacit knowledge that was gained during my construction und the experimentation process allows a different view of the development process in 1928. Against this background, I discuss Walter Müller’s role in the development and the significance of experimental work (...) in Geiger’s laboratory by illustrating the status of data gained from indirect electrical measurements in the field of early radioactivity research. All things considered it was not the instrument itself, but Geiger’s influence and status that affected its establishment in the scientific community in an authoritative way. (shrink)

The bulk of the significant recent scientific heritage of universities is not to be found in accredited science museums or collections employed in research. Rather it is located in a wide variety of more informal collections, assemblages and accumulations. The selection and documentation of such materials is very often unsystematic and many of them are vulnerable to changes of staff, relocation and, above all, shortage of space. Following a survey of views on the values of the recent material heritage of (...) the sciences, I consider the many advantages—for teaching, engagement with wider communities, enhancement of institutional identity and work experience, celebration of scientific achievements, study of the recent history of the practices and fruits of the sciences, etc.—of “multi-site museums” formed through the coordination of such varied and scattered collections. I go on to reflect on ways in which the preservation and display of scientific heritage in dispersed collections may be enhanced and protected through institutional recognition and through provision of guidance and assistance in selection, documentation and digitisation, preservation and conservation, and display. The importance of adequate documentation of the contexts of production and use of objects is stressed, as are the benefits that can result from involvement of student “taskforces” and heritage-concerned scientists.

This article discusses the (re)construction and use of an Early modern instrument, better known as Herman Boerhaave's (1668–1738) little furnace. We investigate the origins, history and materiality of this furnace, and examine the dynamic relationship between historical study and reconstructing and handling an object. We argue that combining textual analysis with performative methods allows us to gain a better understanding of both the role of lost material culture in historical chemical practice, pedagogy, and knowledge production, and provide a deeper understanding (...) of the embodied experiences and knowledge of historical actors. Having made and used two versions of Boerhaave's furnace, we provide insight in what present‐day working models can tell us about historical materials and practices approximately three centuries ago.

This paper offers a novel way of reconstructing conceptual change in empirical theories. Changes occur in terms of the structure of the dimensions—that is to say, the conceptual spaces—underlying the conceptual framework within which a given theory is formulated. Five types of changes are identified: (1) addition or deletion of special laws, (2) change in scale or metric, (3) change in the importance of dimensions, (4) change in the separability of dimensions, and (5) addition or deletion of dimensions. Given this (...) classification, the conceptual development of empirical theories becomes more gradual and rationalizable. Only the most extreme type—replacement of dimensions—comes close to a revolution. The five types are exemplified and applied in a case study on the development within physics from the original Newtonian mechanics to special relativity theory. (shrink)

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

This chapter presents the historical-investigative approach used in science teaching. Both history and philosophy of science have come to a sophisticated understanding of the role that experiments play in the generation and establishment of scientific knowledge. This recent development, called the “experimental turn,” is discussed first. Next, this chapter analyzes how practical work has been discussed among science educators in recent decades. Based on such a broad perspective, the historical-investigative approach is linked to recent advancements in history and philosophy of (...) science and in science education. Several modifications of the historical-investigative approach are outlined in order to illustrate their particular objectives, potential, and richness. (shrink)
