In his recent authoritative Helmholtz and the Conservation of Energy, Kenneth Caneva has claimed that earlier authors had invoked the principle of conservation of living force only in cases of a system returning to an earlier state, or of one without Newtonian forces. Relaying on texts in the tradition of the French Analytical Mechanics form Lagrange to Coriolis, I argue that this was not the case, and that the principle had been formulated and used for cases where living force proper (...) (mv2) was not conserved but its sum with an integral function (refers today as potential) was constant. In addition. I show that contrary to Caneva’s claim, the principle had been connected to the impossibility of creating power out of nothing. The two points indicate a stronger link between the analytical tradition and Helmholtz and his readers than usually portrayed, and the significant contribution of mechanics to the emergence of energy conservation. On a methodological level the use of living force shows that a common term and even a concept, like energy, is not always needed for its successful employment. (shrink)

The idea of an inevitable conflict between science and religion leading to relentless hostility between the two emerged in the nineteenth century and has become a powerful narrative of modernity. Most historians of science trace the origins of the so-called ‘conflict thesis’ to the English-speaking world, more precisely to scientist-historian John William Draper and literary scholar Andrew Dickson White. Their books on the history of scientific-religious conflict turned into bestsellers. Yet, if we look beyond the Anglo-American world, the conflict thesis (...) appears in new historical settings. This paper argues that the science vs. religion narrative flourished already in Germany before Draper and White announced the warfare between science and religion in England and the USA. Focusing on Germany, we aim to show that the conflict thesis emerged in a polycentric process shaped by various political, cultural, and social struggles. It became a rhetorical weapon for liberal scientists in Germany to oppose Ultramontanism and, at the same time, to discredit their rivals as unscientific, fanatic, or even as ‘henchmen’ of the Pope. Our paper makes a case for a decentred approach to the history of the conflict thesis, which brings to the fore specific political and cultural tensions shaping this narrative in the nineteenth century.

Although natural philosophers of Enlightenment Europe shared common ideals, like reliance on reason and natural philosophy, to promote what they deemed to be progress; there were national differences in attitude and disciplinary focus. This paper takes various eligibility criteria as a starting point from which to define a Nordic Enlightenment science; and situates endeavours in climate science within visions of useful science and international conventions for scientific practice. Two perspectives are explored: the make-up of the Nordic Enlightenment science; and the (...) Nordic natural philosopher’s various platforms for work and knowledge transfer. While historians differ as to what constitutes Enlightenment thought and spirit, I establish the existence of a Nordic Enlightenment science by identifying and examining several of its indicators. The paper concludes with a more specific discussion of climate science in Norway in which I show how climate observations performed during the eighteenth century by a sample of Norway’s clergymen and civil servants bear testimony to an internationally-oriented science, through articles produced for science journals and conventions followed for data presentation and instrumentation. The findings corroborate existing knowledge of a progress-driven, Enlightenment science in Nordic countries; reveal differences between countries, and present Norway’s early-modern climate science in an international light.

Species that died without leaving descendants Darwin called ‘utterly extinct’. They far outnumber the ancestors of all living things, so they resemble the dark matter of modern cosmology, which far outweighs visible matter. He realized in 1837 that their absence is what creates the groups in a natural classification. In his Notebook B he combined the idea that species multiply with the idea that ancestors' relatives must mostly be extinct. The fossil Megatherium was utterly extinct. The iconic branching ‘I think’ (...) diagram shows extinction causing the origin of genera by eliminating intermediate species. Darwin’s concept of taxonomic ranks, starting with the genus, was informed by his interaction with taxonomists. Based on his familiarity with demography, Darwin reasoned that the survival of transitional forms was unlikely, which helped him decide to focus at the species level. When drafting his theory in the 1840s, he left out these speculative ideas, but they emerged again in the 1850s when he realized his theory needed a cause for branches to diverge. His ecological answer worked at the species level, but his Principle of Divergence was unconvincing at higher taxonomic levels. In the Origin, Darwin repeatedly insisted on the importance of utter extinction. (shrink)

ABSTRACT As well as the mathematically-supported celestial mechanics that Newton developed in his Principia, Newton also proposed a more speculative natural philosophy of interparticulate forces of attraction and repulsion. Although this speculative philosophy was not made public before the ‘Queries’ which Newton appended to the Opticks, it originated far earlier in Newton’s career. This article makes the case that Newton’s short, unfinished manuscript, entitled ‘De Aere et Aethere’, should be seen as an important landmark in Newton’s intellectual development, being the (...) first work in which Newton assumed there are repulsive forces operating at a distance between the particles of bodies. The article offers an account of how Newton came to write ‘De Aere et Aethere’ and why. It also outlines its relationship to the ‘Conclusio’, with which Newton briefly intended to finish the Principia, and to the ‘Queries’ in the Opticks. The date of the manuscript is disputed, and the article also aims to settle this dispute. Claims that the ‘De Aere et Aethere’ must have been written before the ‘Hypothesis... of Light’ of 1675 are dismissed, and it is suggested, following R. S. Westfall, that it was written after a well-known letter Newton wrote to Boyle early in 1679. (shrink)

ABSTRACT While the link between navigation and astronomy is quite evident and its history has been extensively explored, the prognosticatory element included in astronomical knowledge has been almost completely left out. In the early modern world, the science of the stars also included prognostication known today as astrology. Together with astronomical learning, navigation also included astrology as a means to predict the success of a journey. This connection, however, has never been adequately researched. This paper makes the first broad study (...) of the tradition of astrology in navigation as well as its role in early modern globalization. It shows how astrological doctrine had its own tools for nautical prognostication. These could be used when dealing with the uncertainty of reaching the desired destination, to inquire about the condition of a loved one, or an important cargo. It was widely used, both in time and geographical context, by navigators and cosmographers for weather forecasting and elections for the start of a successful voyage. (shrink)

ABSTRACT This paper examines the rise and fall of the British popular microscopy movement during the decades surrounding the turn of the twentieth century. It highlights that what is currently understood as microscopy was actually two inter-related but distinct communities and argues that the recognized collapse of microscopical societies in the closing decades of the nineteenth century was the result of amateur specialization. It finds the roots of popular microscopy in the Working Men’s College movement and highlights how microscopy adopted (...) its Christian Socialist pedagogy of equality and fraternity, resulting in a radical scientific movement that both prized and encouraged publication by its amateur adherents, who often occupied the middle and working classes. It studies the taxonomic boundaries of this popular microscopy, particularly focusing on its relationship with the study of cryptogams or ‘lower plants’. It explores how its success combined with its radical approach to publication and self-sufficiency created the conditions for its collapse, as devotees established a range of successor communities that had tighter taxonomic bounds. Finally, it shows how the philosophy and practices of popular microscopy continued in these successor communities, focusing on the British expression of mycology, the study of fungi. (shrink)

Information on the origins of the Accademia del Cimento is extremely limited. Almost all of the surviving correspondence relating to the year before the Academy began its activities variously concerns print culture. Lists of books (read, studied, purchased, and researched), handwritten notes on old or new publications, vernacular translations of edited passages, and inquiries about new works punctuate the archive. The study of these lists and of the relationship between reading practices and ones related to annotation and knowledge production leads (...) to a reinterpretation of certain aspects of the Accademia del Cimento, suggesting the pursuit of a more flexible agenda.Through the analysis of some book lists, this contribution aims to shed light on the presence in Florence of interconnected groups of scholars, common epistemic practices, and a kind of methodological unity centred on the sharing of materials and agreement concerning the need to subject theories to experimental verification.

At the end of the 1920s, Tanganyika Territory experienced several serious rodent outbreaks that threatened cotton and other grain production. At the same time, regular reports of pneumonic and bubonic plague occurred in the northern areas of Tanganyika. These events led the British colonial administration to dispatch several studies into rodent taxonomy and ecology in 1931 to determine the causes of rodent outbreaks and plague disease, and to control future outbreaks. The application of ecological frameworks to the control of rodent (...) outbreaks and plague disease transmission in colonial Tanganyika Territory gradually moved from a view that prioritised 'ecological interrelations' among rodents, fleas and people to one where those interrelations required studies into population dynamics, endemicity and social organisation in order to mitigate pests and pestilence. This shift in Tanganyika anticipated later population ecology approaches on the African continent. Drawing on sources from the Tanzania National Archives, this article offers an important case study of the application of ecological frameworks in a colonial setting that anticipated later global scientific interest in studies of rodent populations and rodent-borne disease ecologies.

Today, we take international collaborations as a necessity, but 150 years ago, when travel was not so convenient, it involved an enduring and time-consuming challenge. This paper presents letters and reports written by German physicist Julius Plücker to his wife, Antonie née Altstädten describing his travels to Great Britain and France between 1853 and 1866. These letters provide a view into how international collaboration and communication were developed and maintained as well as how friendships were built within the scientific community (...) during the early industrial age, prior to telegraph, telephone, email, and internet.

The organization of the mobile atomic exhibition, Mostra Atomica, designed by the United States Information Service to travel through Italy in 1954–55, had to meet technical, scientific, artistic, and political challenges. The head of the group in charge of the exhibition was architect Peter G. Harnden whose pedigree in the intelligence and training in architecture were an ideal match for leading the unit dedicated to exhibitions. The political sensitivity of the Mostra Atomica also required the intervention of the Italian Ministry (...) of the Interior to guarantee safe mobility and secure shows. In every major town, American and British diplomats attended the local opening ceremony, while the very symbol of science diplomacy was Enrico Fermi, whose recorded message praised international cooperation. All in all, the USIS campaign promoting peaceful applications of nuclear physics was successful in reaching and involving Italian society. Visual and spatial aesthetics were particularly relevant: the geometrical design of the exposition rooms conveyed a strong sense of modernity that contrasted with the artistic heritage of Italian cities. The present article is based on archival files, newspaper reports, and photographs that document who was responsible for planning, setting up, and reporting this Cold War propaganda event. (shrink)

ABSTRACT Despite the increasing interest in science exhibitions, there has been hardly any work on mobile science exhibitions and their role within science diplomacy – a gap this thematic issue is meant to fill. Atomic mobile exhibitions are seen here not only as cultural sites but as multifaceted strategic processes of transnational nuclear history. We move beyond the bipolar Cold War history that portrays propagandist science exhibitions as instances of a one-way communication employed to promote the virtues of the two (...) major and conflicting political powers. Instead, Science Diplomacy on Display follows mobile atomic exhibitions as they move across national borders and around the world, functioning as spaces for diplomatic encounters. Exhibitions play a vital role not only in the production of knowledge and the formation of political worldviews but also as assets in diplomatic negotiations and as promoters of a new worldview in which nuclear stands at the centre. They are powerful iconic diplomatic devices, that is systems of representations that capture the diplomatic processes in action and make the nitty-gritty details of international relations visible. This issue seeks to trace the multiple and often contradictory meanings that mobile exhibitions took on for various actors. (shrink)

During the IAEA’s Mobile Radioisotope Exhibition (1960–1965) through the eventful roads of five Latin American countries (Mexico, Uruguay, Argentina, Brazil, and Bolivia), a variety of photographs were taken by an unknown Mexican official photographer, and by Josef Obermayer, a staff driver from Vienna. The exhibition carried not only bits of nuclear sciences and technologies, but also the political symbolism of the ‘friendly atom’ as a token of modernization. The photographs embarked on different trajectories, though all of them ended up at (...) the training and exchange official’s desk in charge of the exhibition, Argentinian physicist Arturo Cairo. The ones taken in Mexico also had a local circulation as propaganda intended to promote radioisotope applications. The two sets of images were intended to show the contrast between modernity and traditional society, but they did it from different gazes. Our paper argues that, in the case of Mexico, the photographer reinforced representations of the country which were already popularized by Hollywood for foreign and local audiences. On the other hand, the Viennese photographer’s gaze delivers an autoethnography of his dutiful journey. We also argue that Obermayer’s projection is one of what Roger Bartra has conceptualized as the ‘salvage on the mirror’. (shrink)

The Czechoslovak-Soviet exhibition ‘Atoms for Peace’ was held in Prague and Bratislava in 1956. This exhibition became a symbol of Czechoslovak-Soviet ‘friendship’ and Soviet influence on the Czechoslovak nuclear programme. At the Brussels World’s Fair in 1958 (Expo 58), one of the most popular Czechoslovak exhibits was the betatron, which would become a symbol of Czechoslovak nuclear pride. The article analyzes the planning, creation and reception of these two exhibitions, as well as the popular image of the Czechoslovak betatron in (...) the Czechoslovak press and literature of that time. It shows how, in Czechoslovakia, the paradigm of Czechoslovak-Soviet friendship and Soviet dominance converged and became entangled with the effort to present Czechoslovakia as an industrially developed country capable of building the nation’s nuclear industry (partly) on its own. One of the results of this entanglement was the betatron – a highly successful and celebrated Czechoslovak nuclear exhibit that captivated both domestic and international audiences. (shrink)
