In fin de siècle Argentina a secularist ideology of science was part of the positivist world view espoused by liberals and socialists. Between the years 1910 and 1935, a period in which the Catholic Church experienced a significant cultural expansion, the activities of the Catholic naturalist Ángel Gallardo and the astronomer and priest Fortunato Devoto challenged the so far prevailing idea of science as opposed to religion. This paper explores the connections between the scientific, religious and political aspects of those figures in order to get some insights into the complexity of the relationships between science and secularization in societies with a Catholic majority.

This paper uses a case study of a 1970s controversy in artificial-intelligence (AI) research to explore how scientists understand the relationships between research and practical applications. It is part of a project that seeks to map such relationships in order to enable better policy recommendations to be grounded empirically through historical evidence. In 1972 the mathematician James Lighthill submitted a report, published in 1973, on the state of artificial-intelligence research under way in the United Kingdom. The criticisms made in the report have been held to be a major cause behind the dramatic slowing down (subsequently called an ‘AI winter’) of such research. This paper has two aims, one narrow and one broad. The narrow aim is to inquire into the causes, motivations and content of the Lighthill report. I argue that behind James Lighthill's criticisms of a central part of artificial intelligence was a principle he held throughout his career – that the best research was tightly coupled to practical problem solving. I also show that the Science Research Council provided a preliminary steer to the direction of this apparently independent report. The broader aim of the paper is to map some of the ways that scientists (and in Lighthill's case, a mathematician) have articulated and justified relationships between research and practical, real-world problems, an issue previously identified as central to historical analysis of modern science. The paper therefore offers some deepened historical case studies of the processes identified in Agar's ‘working-worlds’ model.

This article situates Edward Gresham's Astrostereon, or A Discourse of the Falling of the Planet (1603), a little-known English astronomical treatise, in the context of the cosmo-theological debate on the reconciliation of heliocentrism with the Bible, triggered by the publication of Nicholas Copernicus's De revolutionibus orbium coelestium in 1543. Covering the period from the appearance of the ‘First Account’ of Copernican views presented in Georg Joachim Rheticus's Narratio Prima (1540) to the composition of Astrostereon in 1603, this paper places Edward Gresham's commentary and exegesis against the background of the views expressed by his countrymen and the thinkers associated with the Wittenberg University – such as Philipp Melanchthon, Caspar Peucer, and Christoph Rothmann. Comparing the ways in which they employed certain biblical passages – either in favour of or against the Earth's mobility – the paper emphasizes Gresham's ingenious reading of the Hebrew version of the problematic excerpts, and his expansion of the accommodation principle.

Britain's nineteenth-century railway companies traditionally play a central role in histories of the spread of standard Greenwich time. This relationship at once seems to embody a productive relationship between science and capitalism, with regulated time essential to the formation of a disciplined industrial economy. In this narrative, it is not the state, but capitalistic private commerce which fashioned a national time system. However, as this article demonstrates, the collaboration between railway companies and the Royal Greenwich Observatory was far from harmonious. While railways did employ the accurate time the observatory provided, they were also more than happy to compromise the astronomical institution's ability to take the accurate celestial observations that such time depended on. Observing astronomical transits required the use of troughs of mercury to reflect images of stars, but the construction of a railway too near to the observatory threatened to cause vibrations which would make such readings impossible. Through debates over proposed railway lines near the observatory, it becomes clear how important government protection from private interests was to preserving astronomical standards. This article revises our understanding of the role of railway companies in the dissemination of standard time and argues that state intervention was essential to preserving Victorian British astronomical science.

In 1962 a team of scientists conducted their first joint fieldwork in a Xavante village in Central Brazil. Recycling long-standing notions that living Indigenous people represented human prehistory, the scientists saw Indigenous people as useful subjects of study not only due to their closeness to nature, but also due to their sociocultural and political realities. The geneticists’ vision crystalized around one subject – the famous chief Apöwẽ. Through Apöwẽ, the geneticists fixated on what they perceived as the political prowess, impressive physique, and masculine reproductive aptitude of Xavante men. These constructions of charismatic masculinity came at the expense of recognizing how profoundly colonial expansion into Mato Grosso had destabilized Xavante communities, stripping them of their land and introducing epidemic disease. The geneticists’ theorizing prefigured debates to come in sociobiology, and set up an enduring research programme that Apöwẽ continues to animate even four decades after his death.

In the context of the telegraphic distribution of Greenwich time, while the early experiments, the roles of successive Astronomers Royal in its expansion, and its impacts on the standardization of time in Victorian Britain have all been evaluated, the attempts of George Biddell Airy and his collaborators in constructing the Royal Observatory's time signals as the authoritative source of standard time have been underexplored within the existing historical literature. This paper focuses on the wide-ranging activities of Airy, his assistant astronomers, telegraph engineers, clockmakers and others, which served to increase the reliability of the Royal Observatory's time service between the 1850s and 1870s. Airy and his collaborators aimed to mechanize and automate their telegraphic time distribution system in order to improve its accuracy and reliability. The accomplishment of such technological innovations was disseminated via public lectures, journal articles and correspondence with experts, secondary distributors of standard time and the general public. These communications were used to build public trust in the Greenwich time service. However, the unexplored archival material used in the present paper provides fresh insight into the unstable nature of the Greenwich time system, including its clear limits in terms of its scale of automation and degree of accuracy.

Collecting seeds and specimens was an integral aspect of botany and natural history in the eighteenth century. Historians have until recently paid less attention to the importance of collecting, trading and compiling knowledge of their cultivation, but knowing how to grow and maintain plants free from disease was crucial to agricultural and botanical projects. This is particularly true in the case of food security. At the close of the eighteenth century, European diets (particularly among the poor) began shifting from wheat- to potato-dependence. In Britain and Ireland during these decades, extensive crop damage was caused by diseases like ‘curl’ and ‘dry rot’ – leading many agriculturists and journal editors to begin collecting data on potato cultivation in order to answer practical questions about the causes of disease and methods that might mitigate or even eliminate their appearance. Citizens not only produced the bulk of these data, but also used agricultural print culture and participation in surveys to shape and direct the interpretation of these data. This article explores this forgotten scientific ambition to harness agricultural citizen science in order to bring stability and renewed vitality to the potato plant and its cultivation. I argue that while many agriculturists did recognize that reliance upon the potato brought with it unique threats to the food supplies of Britain and Ireland, their views on this threat were wholly determined by the belief that the diseases attacking potato plants in Europe had largely been produced or encouraged by erroneous cultivation methods.

This article suggests that, during the 1820s and 1830s, Britain experienced a mirage moment. A greater volume of material was published on the mirage in scientific journals, treatises, travel literature and novels during these two decades than had occurred before in British history. The phenomenon was examined at the confluence of discussions about the cultural importance of illusions, the nature of the eye and the imperial project to investigate the extra-European natural world. Explanations of the mirage were put forward by such scientists and explorers as Sir David Brewster, William Wollaston and General Sir James Abbott. Their demystification paralleled the performance of unmasking scientific and magical secrets in the gallery shows of London during the period. The practice of seeing involved in viewing unfathomable phenomena whilst simultaneously considering their rational basis underwrote these different circumstances. I use this unusual mode of visuality to explore the ways the mirage and other illusions were viewed and understood in the 1820s and 1830s. Ultimately, this paper argues that the mirage exhibited the fallibility of the eyes as a tool for veridical perception in a marvellous and striking way, with consequences for the perceived trustworthiness of ocular knowledge in the period.

This paper draws on material from the dissertation books of the University of Edinburgh's student societies and surviving lecture notes from the university's professors to shed new light on the debates on human variation, heredity and the origin of races between 1790 and 1835. That Edinburgh was the most important centre of medical education in the English-speaking world in this period makes this a particularly significant context. By around 1800 the fixed natural order of the eighteenth century was giving way to a more fluid conception of species and varieties. The dissolution of the ‘Great Chain of Being’ made interpretations of races as adaptive responses to local climates plausible. The evidence presented shows that human variation, inheritance and adaptation were being widely discussed in Edinburgh in the student circles around Charles Darwin when he was a medical student in Edinburgh in the 1820s. It is therefore no surprise to find these same themes recurring in similar form in the evolutionary speculations in his notebooks on the transmutation of species written in the late 1830s during the gestation of his theory of evolution.

This article, through a case study of the Royal Dublin Society (RDS), traces the reception, experimentation with, and uses of radium in early twentieth-century Ireland. Throughout the nineteenth century there was increasing state intervention in the provision of scientific and technical education in Ireland. This culminated in the loss of the RDS's traditional role in this area. The article demonstrates that the RDS was forced to re-envisage its role as a scientific institution by actively seeking to support experimental research. Using radium as a case study, the article argues for the success of this tactic. It demonstrates that radium played a central role within the RDS as a nexus for the maintenance of an experimental and philanthropic culture that permeated much of the society's scientific output in this period. In doing this it highlights the importance of sociability in the promotion of science in Ireland in the early twentieth century. In addition, it explores the role of the RDS as an arbiter of scientific authority.

This article explores the networking activities of Count Nikolai Rumiantsev and Adam von Krusenstern, his close collaborator. The visionary Russian statesman and the celebrated navigator were deeply involved in northern exploration. They funded and organized a circumnavigating voyage by the brig Rurik in 1815–18, with the explicit goals of searching for a northern passage between Eurasia and North America and conducting a series of scientific investigations in the Bering Strait region. This private exploratory enterprise profoundly influenced the exchange of information and reconfigured both local and global networks of knowledge. Based on an analysis of private correspondence, printed accounts and journal articles related to the Rurik's expedition, this study sheds light on how this transnational network of actors emerged and functioned, and how it promoted a lively circulation of information about exploration in the Bering Strait region in the 1810s–1820s. I argue that a complex interplay of geopolitical and intellectual competition, with exchanges, collaborations and coordination among various actors (e.g. patrons, navigators, scholars, entrepreneurs and publishers), stimulated further research on the global ocean's northern spaces and laid the foundations of marine science.

Around 1960, leading figures in the international conservation circuit – such as Julian Huxley, Frank Fraser Darling and E. Barton Worthington – successfully propagated new visions about the value of undomesticated African mammals. Against traditional ideas, they presented these mammals as a highly efficient source of protein for growing African populations. In line with this vision, they challenged non-interventionist ideals of nature preservation, and launched proposals for active management through game ‘ranching’ and ‘cropping’. As such, they created a new socio-technical imaginary for Africa's future, in which the consumption of wildlife meat took up a central position. This article explores the motivations of Western conservationists for this drastic rebranding. It argues that the rationale of considering African wildlife in terms of protein played an important symbolical role at various levels. It was crucial in the reorganization of the transnational networks of conservation, but also in the boosting of their scientific reputation, in the restructuring of their institutional ties, and in their attempts to maintain an authoritative position for Western ecologists in a rapidly decolonizing world.

This essay explores how hormone treatments were used to optimize and normalize individuals under Italian Fascism. It does so by taking the activities of the Biotypological Orthogenetic Institute − an Italian eugenics and endocrinological centre founded by Nicola Pende in 1926 − as the prime example of a version of eugenics, biotypology, which was based on hormone therapies. This essay first demonstrates that Italian Fascist biopolitics was not only concerned with increasing the size of the Italian population, but also with improving its quality. It suggests that under the Italian Fascist regime hormone therapies became eugenic tools of intervention to improve the Italian race. Second, while Pende's institute purportedly enhanced men and women, its activities show the extent to which the ‘techniques of normalization’ pursued by the Fascist regime were both systematic and invasive.

Today, the most powerful research technique available for assigning chronometric age to human cultural objects is radiocarbon dating. Developed in the United States in the late 1940s by an alumnus of the Manhattan Project, radiocarbon dating measures the decay of the radioactive isotope carbon-14 (C14) in organic material, and calculates the time elapsed since the materials were removed from the life cycle. This paper traces the interdisciplinary collaboration between archaeology and radiochemistry that led to the successful development of radiocarbon dating in the early 1950s, following the movement of people and ideas from Willard Libby's Chicago radiocarbon laboratory to museums, universities and government labs in the United States, Australia, Denmark and New Zealand. I show how radiocarbon research built on existing technologies and networks in atomic chemistry and physics but was deeply shaped by its original private philanthropic funders and archaeologist users, and ultimately remained to the side of many contemporaneous Cold War scientific and military projects.

While some seventeenth-century scholars promoted natural history as the basis of natural philosophy, they continued to debate how it should be written, about what and by whom. This look into the studios of two Amsterdam physicians, Jan Swammerdam (1637–80) and Steven Blankaart (1650–1705), explores natural history as a project in the making during the second half of the seventeenth century. Swammerdam and Blankaart approached natural history very differently, with different objectives, and relying on different traditions of handling specimens and organizing knowledge on paper, especially with regard to the way that individual observations might be generalized. These traditions varied from collating individual dissections into histories, writing both general and particular histories of plants and animals, collecting medical observations and applying inductive reasoning. Swammerdam identified the essential changes that insects underwent during their life cycle, described four orders based on these ‘general characteristics’ and presented his findings in specific histories that exemplified the ‘general rule’ of each order. Blankaart looked to the collective observations of amateurs to support his reputation as a man of medicine, but this was not supposed to lead to any kind of generalization. Their work alerts us to the variety of observational practices that were available to them, and with what purposes they made these their own.

Anglo-Swedish scholarly correspondence from the mid-eighteenth century contains repeated mentions of two merchants, Abraham Spalding and Gustavus Brander. The letters describe how these men facilitated the exchange of knowledge over the Baltic Sea and the North Sea by shipping letters, books and other scientific objects, as well as by enabling long-distance financial transactions. Through the case of Spalding and Brander, this article examines the material basis for early modern scholarly exchange. Using the concept of logistics to highlight and relate several mercantile practices, it examines ways of making scholarly knowledge move, and analyses merchants’ potential motives for offering their services to scholarly communities. As logisticians in the Republic of Letters, these merchants could turn their commercial infrastructure into a generator of cultural status valid in both London and Stockholm. Using mercantile services, scholarly knowledge could in turn traverse the region in reliable, cost-effective and secure ways. The case of Spalding and Brander thus highlights how contacts between scholarly communities intersected with other contemporary modes of transnational exchange, and it shows how scholarly exchange relied on relationships based on norms different from the communalism often used to characterize the early modern Republic of Letters. Thus the article suggests new ways of studying early modern scholarly exchange in practice.

From 8 February until at least 19 April 1686, the Dublin Philosophical Society was occupied with a prodigiously talented young girl whose name was never recorded. She was less than eleven years of age, but still much older than the society itself, which had begun meeting less than three years previously. Although one of many wonders engaging the curiosity of the nascent society, this girl served a surprising range of purposes, so that accompanying her anonymity was a curious malleability. Pressed into several different roles and identities, her exploitation affords a glimpse into the various qualities that could make a spectacle useful in a philosophical climate that was unique among the British Isles. The use of this girl therefore not only sheds light on the needs of a less familiar learned society, but also shows how these could differ from those of its better-understood counterparts. For a period of time, it was the versatility not of the gentlemen in Dublin, but of the prodigy they used, that best served this group on the periphery.

John Maynard Smith (1920–2004) was one of Britain's most eminent evolutionary biologists. For over forty years, from 1954 onwards, he also regularly appeared on radio and television. He primarily acted as a scientific expert on biology, but in the late 1960s and the 1970s he often spoke on the implications of science (biology and more generally) for society. Through four case studies, this paper analyses Maynard Smith's scientific broadcasting against developments within the BBC as well as the relation between science and society in Britain. It finds that while Maynard Smith acknowledged and accepted increasing mediation through the BBC and its producers, he stayed publicly and privately critical of both format and content decisions in his reflections on the science–media relationship. At the same time, we find that over a decade before the 1985 report by the Royal Society on the public understanding of science, Maynard Smith came to think of engagement with the public via the media as scientists’ responsibility.

This article analyses the production and reception of the natural history film series Secrets of Nature (1919–33) and its sequel Secrets of Life (1934–47), exploring what these films reveal about the role of cinema in public discourses about science and nature in interwar Britain. The first part of the article introduces the Secrets using an ‘intermedial’ approach, linking the kinds of natural history that they displayed to contemporary trends in interwar popular science, from print publications to zoos. It examines how scientific knowledge was communicated in the series, especially the appeal to everyday experience as a vehicle to engage mass audiences with scientific subjects. The second part examines the Secrets series through the lens of knowledge co-production, detailing how a range of different figures, including academic scientists, nature photographers, producers and teachers, became entangled in making the films. Recovering the term ‘ciné-biology’, it argues that Secrets developed a unique style of filmmaking that generated cultural space for the life sciences in British popular culture. The third part analyses two interwar cinema experiments to explore how audiences, imagined and real, shaped the kinds of natural knowledge characterized by the Secrets films.

Two aerodynamic concepts theorized in the early twentieth century – laminar-flow control and flying wings – offer the potential for more efficient aircraft. However, despite compelling advantages on paper and optimistic predictions, the fuel-saving benefits of these technologies have not yet been fully realized. This paper documents British work on these concepts, with a particular focus on laminar-flow control. Faced with an increasingly difficult funding context and a lack of a clear military rationale, these potentially significant advances in aircraft efficiency were stymied by a catch-22: the government was only prepared to provide financial support for the development of an operational prototype if operational performance had already been demonstrated. This case also highlights the challenges faced in the commercial uptake of radical aviation technologies, even when they appear to offer greater efficiency and environmental benefits.
