This study examines the historical transformations and multifaceted applications of stalactite (shizhong ru) in premodern China (3rd c. BCE-17th c. CE). Initially regarded as an elixir for consumption, stalactite gained popularity due to its perceived medicinal benefits, especially as a safer alternative to the toxic Five-Stone Powder. However, its usage declined due to increasing medical concerns, quality inconsistencies, and regional climatic factors, particularly in southern China. As doubts over safety intensified, stalactite was gradually relegated from "non-toxic" dietary use to cautious prescription and eventually became the subject of debates on its toxic potential. At the same time, its restorative logic extended beyond the human body to agriculture. Over time, its application re-emerged in both medical and agricultural contexts, where it was applied to enhance fertility and vitality. By tracing these shifts through historical and medical texts as well as environmental factors, this study highlights the dynamic relationship between natural resources, medicine, and societal needs, offering new insights into the evolution of mineral-based therapeutics for land as well as humans in premodern China.

Drawing on previously unknown sources, this article documents the physicist Johannes Stark's unsuccessful attempt to publish a declaration by German Nobel laureates in support of the August 1934 referendum. Following the death of Reich President Paul von Hindenburg, this referendum aimed to legitimize the transfer of the two highest state offices-Reich President and Reich Chancellor-to one single person, thereby making Adolf Hitler the head of state and Führer of the German people. At the suggestion of the Propaganda Ministry, Stark sent a telegram to eleven "Aryan German Nobel laureates" in chemistry and physics, and urged them to sign a public appeal to participate in the referendum and support "the great national commitment of the entire German people" to Adolf Hitler as "Führer of the German people." Responses to Stark's telegram ranged from wholehearted support to rejection. The majority of the laureates declined to lend their signature, and the initiative ultimately failed. The episode reveals that Stark-although at the height of his influence as president of the Physikalisch-Technische Reichsanstalt (Imperial Institute of Physics and Technology) and the Deutsche Forschungsgemeinschaft (German Research Foundation)-was largely isolated within the scientific community of the so-called Third Reich.

How is historical evidence conveyed? How could an eighteenth-century scholar vouch for the information stored on paper, drafted with the quill, and publicized in copperplate engravings or letterpress? In this article, I employ material and medial perspectives to reconstruct the multiple production stages of Johann Christoph Gatterer's Historia genealogica dominorum Holzschuherorum (1755) and, thereby, reveal how historical knowledge was shaped by the media that presented it. By focusing not only on the text but mainly on the engraved plates inserted within the pages of this work, I will reveal how, in the eighteenth century, historical knowledge was collectively achieved through complex scholarly, artistic, and editorial negotiations that encompassed issues of authorship and intellectual authority as well as disputes that occurred both in the making of visual evidence and the trading of authoritative editions. After exploring many drawn, handwritten, typeset, and engraved sources related to this editorial project, I argue that Gatterer's work relied on an information system based on the interplay between verbal and visual information and their relationship to the material evidence of the past. Moreover, I show how this system itself was shaped by the different media that it, in turn, used to reproduce historical evidence.

Wie kann man einen historischen Blick auf das eigene Fach werfen? Diese Frage ist nicht einfach zu beantworten - will man einerseits nicht in einer Nabelschau und Hagiographie enden, andererseits aber auch keinen umfassenden Entwurf einer zukünftigen Historiographie vorlegen. Die hier in loser Folge publizierten Interviews mit bekannten Protagonist:innen der Berliner Wissenschaftsgeschichte von ca. 1970-1990 in West und Ost rücken die Geschichte des Faches deshalb in einem bestimmten Milieu in den Fokus und versuchen, die Historiographie jenseits einer Institutionen- oder Theoriegeschichte voranzutreiben. Welche Motivationen oder Probleme bewegten einzelne Wissenschaftler:innen, sich der Geschichte ihres Faches zu widmen oder sich etwa aus der Soziologie oder Philosophie in die Wissenschaftsgeschichte zu bewegen? Welche Ausbildungspraktiken existierten in diesem heterogenen, zwischen den Disziplinen angesiedelten Feld, welche Anregungen bezog man aus welchen Kontexten? Wie war Lehre strukturiert und welche Netzwerke bildeten sich mit der Zeit? Kurz: Mit welchem Interesse kam man zur Wissenschaftsgeschichte und was wurde daraus? Die Auswahl der Interviewees erfolgt ohne Anspruch auf Vollständigkeit oder Proporz; der Fragenkatalog der Interviews richtet sich individuell nach den Biographien und dem Werk und entfaltet sich oft spontan im Gespräch. Die Interviews wurden digital aufgezeichnet, transkribiert, der Schriftsprache angepasst, gegebenenfalls gekürzt, annotiert und von den Interviewees authentifiziert. Wir beabsichtigen mit dieser Serie von Interviews zunächst die Dokumentation rezenter Geschichte durch eine Oral History, die subjektive Wahrnehmungen und persönliche Erlebnisse einschließt. Auf diese Weise werden Segmente einer größtenteils ungeschriebenen Geschichte anhand von Biographien erfahrbar und damit auch einer weiteren kritischen Bearbeitung und Integration in ein Gesamtbild zugänglich. Da uns im Zuge der jeweiligen Vorbereitung und Durchführung, Transkription und Abstimmung der Interviews daran gelegen war, aus Sicht der Akteur:innen wichtige Sammelbände und Aufsätze, Monographien oder auch "graue Literatur" zu erfassen, wird nebenbei eine kommentierte Bibliographie zur Geschichte der Wissenschaftsgeschichte entstehen. Unsere Hoffnung besteht darin, mittels dieser Sammlung mit Berlin einen fruchtbaren Raum und mit den siebziger und achtziger Jahren eine produktive Zeit des Faches jenseits von Reminiszenz oder Nostalgie zu erkunden - nicht zuletzt auch, um den Blick für gegenwärtige Herausforderungen des Faches zu schärfen.

The article is based on the hitherto unknown correspondence between the Polish scholar and founder of the Slavic-Philological Seminary in Breslau, Władysław Nehring (1830-1909), and the secret Prussian Minister of Culture Friedrich Althoff (1839-1908). The archival material sheds new light on the establishment and early years of the institution and the background to Prussian science policy. Nehring's self-portrayal and the incorrect dating of the founding of the institute, which has so far not been scrutinized by researchers, only provide a very inadequate picture of the circumstances of its origins. Finally, the widespread idea of Althoff as despiser of professors also needs to be reconsidered in this context.

Edmond Locard's L'enquête criminelle et les méthodes scientifiques marks a pivotal moment in criminology's transformation from a largely unmethodical practice to a scientific discipline. While Locard is best known for advancing laboratory methods of forensic analysis, this article argues that at the heart of his conception of forensics lies the assertion that it is not rationality, but vivid imagination that makes or breaks the criminal investigation. Following Locard's claim that one of the most crucial challenges in teaching forensics is to introduce fellow criminologists to the art of using intuition and creativity for problem-solving, this article examines the concrete ways in which L'enquête criminelle attempts to actively engage the reader's imaginative faculty by presenting problems that can only be solved through "lateral thinking" and "abductive reasoning." To introduce his speculative methods, I argue, Locard borrows from detective fiction in two ways: Firstly, he counterfactually presents literary case studies by Poe as real-world cases, endorsing Dupin's detective technique as a viable criminological practice. By planting hidden clues and red herrings in semiotic puzzles to be deciphered by the reader, secondly, Locard appropriates narrative techniques to sharpen his reader's hermeneutics instincts.

A key difference between collecting life stories and doing research interviews is the role of the interviewer. While training in oral history may focus on using standard scripts to take a life story, research interviews are motivated by specific questions that arise from particular historical projects and are often not primarily focused on the biography of the interviewee. Therefore, the research interview can be seen as being both less personal with regard to the personal life story of the interviewee and more personal with respect to the foregrounding of the specific interests of the interviewer. Soraya de Chadarevian has been one of the first historians of science to systematically reflect on this and other differences between life story interviews and research interviews. In this contribution, Lara Keuck, who has herself made use of interviews in her research, interrogates de Chadarevian on her approach to research interviews in her historical practice. They discuss how de Chadarevian's personal approach has developed and changed over the past three decades and reflect on the methodological implications that can be distilled from this experience.

This paper presents initial findings on the interaction between astronomical procedures on Babylonian tablets. Using algorithms as a lens, this research investigates the relationship between procedures, data provided on the tablet, and the representations of methods within the tablets. This paper first provides a critical analysis of the term "algorithm" in a historical, Mesopotamian context and how algorithms may be used as an analytical tool for thinking about the relationship between astronomical procedures. Following this description, the paper moves on to discuss a case study from the planetary procedure texts that showcases how an algorithm-based analysis can inform reinterpretations of how the individual procedures interact on a given tablet. The ultimate goal of this work is to shed new light on how the authors and users of these astronomical tablets may have interacted with them.

This paper examines how an International Atomic Energy Agency (IAEA) expert mission for technical assistance in the late 1950s to Greece was effectively transformed into a mission to achieve the IAEA's central objective: to consolidate its position as the leading global authority on radiation protection. The study focuses on the work of Alfred Maddock, a professor at the University of Cambridge. In 1959, Maddock arrived in Greece as part of one of the IAEA's original missions, contributing to an educational program on radioisotopes. Beyond providing educational services, Maddock accomplished something more significant. As the Agency's facilitator, he introduced radiation protection materials and concepts to the country in accordance with the IAEA protocols. He introduced dosimetry devices (film badges) and, at the same time, reviewed, modified, and created architectural plans for the laboratories of the Greek Nuclear Centre to meet the IAEA safety standards. It is argued that Maddock's visit to Greece transcended a mere one-sided enforcement process. Rather, it catalyzed a dynamic interaction between Greece and the IAEA, characterized by robust elements of mutual cooperation. This mission stands as a prime example of the gradual integration of IAEA culture within a member state, tailored to local needs and conditions.

The term "epistemic object" has been recently used by some scholars in the history and philosophy of science to refer to the peculiar history of objects of inquiry such as RNA, genes, electrons, or phlogiston. Despite the relative success of this neologism as an analytical tool, a comprehensive analysis of its many versions is still lacking. In this article, an attempt has been made to sketch such an analysis first by comparing three main versions of this idea: epistemic things, epistemic objects, and representations of theoretical entities. Second, these conceptions are compared with the notion of scientific concept, arguing that, although similar, they are not the same thing. However, a proposal suggested from the history of concepts program, Klaus Hentschel's semantic layered methodology, could be usefully adapted for epistemic things. Third, accomplishing such adaptation by drawing from the tradition of evolutionary epistemology is recommended, analyzing the potential fit between historical epistemology and the Evolutionary Epistemology of Theories programme.

In 1976, the year that Werner Heisenberg passed away, Armin Hermann published a short biography, titled Werner Heisenberg in Selbstzeugnissen und Bilddokumenten. Since then, historians and biographers have offered their accounts on Heisenberg's life and his contributions to modern physics. Many of these biographies present Heisenberg as a genius. Upon closer inspection, the ideal of the genius relies on the topos of the experience of knowledge presented in Heisenberg's memoir from Der Teil und das Ganze. Gespräche im Umkreis der Atomphysik. This article discusses the influence of this topos on his biographies. The article first contextualizes Heisenberg's popular science texts among his academic career and the cultural contexts of the German Bildungsbürgertum. Second, it focuses on the aesthetic repertoire of knowledge production as the experience of knowledge. By going beyond the semantic level, it is shown that the topos of the experience of nature in Heisenberg's memoir is central to his scientific persona. Ultimately, the idea of the genius stands in a longue durée of German Romanticism and natural philosophy is shown to shape the masculinities and scientific personae of the modern physicist.

In 1961, the National Aeronautics and Space Administration (NASA) and the Franklin Institute, a popular science museum in Philadelphia, PA, launched a mobile science education program in the U.S. called the Spacemobile. The program went international a year later, touring 53 countries by 1969. NASA's Educational Programs Division, part of the Public Affairs Department, collaborated with the U.S. Information Agency (USIA) and the U.S. State Department to facilitate the international circulation of science education diplomacy at the height of the early Cold War. Using primary sources from NASA, the USIA, the State Department, oral histories, and memoirs, it is argued that the Spacemobile program mediated the circulation of NASA's technoscientific knowledge and materials around the world by teaching the basic science behind the space program to students and other public audiences. Mediation Occurred when the Spacemobile program accompanied NASA's technoscientific collaboration and exchange agreements, confirms geopolitical alliances, eased sociopolitical tensions over tracking station expansion, and when it appealed to student audiences receptive to Western ideological perspectives about space science.

Short-lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles-an integral part of the conceptual framework of quantum field theory (QFT)-exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status. Central to these debates is Richard Feynman's diagrammatic technique for QFT calculations, which provided in the late 1940s the first systematized and generalized description of the concept of virtual particles. At the time, however, the curious characteristics and the ontology of the latter were the subject of little, if any, debate. This article explores how the concept of virtual particles gradually became subject to interpretative scrutiny in the post-war period. It examines the weight of various aspects of pre-Feynman developments which once guaranteed a firmer phenomenological anchoring of the scientific practices associated with the virtual particle concept. Subsequently, it shows how the questioning of this concept did not result from a simple assessment of its curious characteristics but was part of a wider critique of the new quantum electrodynamics and Feynman's methods.

The 2011 Fukushima Daiichi Nuclear Power Plant accident underscored the crucial role of nuclear engineering experts. However, the specific arguments and motivations of scientists advocating for the introduction of foreign reactors remain unclear. This study delves into the contribution of Ryōkichi Sagane (1905-1969), a prominent figure during their introduction, and analyzes the specifics of his arguments for the importation of reactors examining his motivations and background. Sagane, who studied nuclear physics in the U.S., gained expertise in nuclear experiments and became acquainted with American scientists. In the late 1950s, with the period of Japan's adoption of nuclear power, he understood the arguments of foreign and domestic experts and disseminated this information to the public. His claims for importation of reactors rested predominantly on the ground of economic and managerial rationality. Beyond mere rationalism, Sagane's drive for reactor introduction was rooted in international humanitarianism based on personal friendships that transcended national borders. The rhetoric of promoting nuclear power for the sake of humanity resonated with the nuclear energy policy of the U.S. during the early Cold War. However, unlike the motivation of the U.S. to suppress opposition to the development of nuclear weapons, Sagane's motivation arose from his scientific practice.

When cosmic rays-high-energy particles from outer space-encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic-ray background radiation. I examine how the first such detection of neutrinos in 1965 by an international team of physicists at the Kolar Gold Fields (KGF) in India-a gold mine where the British began mining in 1880-was made possible by the invisible labor of lowered-caste, or Dalit, miners. By studying the underground, this paper contributes to recent attention to verticality in the history of science, while moving away from the dominant approach to spatial studies of sites of science, the lab-field framework, and instead examining the social, political, and economic conditions that made KGF, with its depth, possible as a site for physics. Using labor histories of KGF and archival material about the experiments, I argue that the mines became nearly three kilometers deep only because of a regime of racialized labor in which Dalit miners worked in difficult and dangerous conditions for less than subsistence-level wages. I also show how the experiments depended on this invisible labor that ran the mines.

Ever since Erwin Schrödinger learned about Indian thought through Arthur Schopenhauer, it occupied a visible role in both his published writings and personal books. Schrödinger called for a "blood transfusion" of Indian thought into the West and, in one notebook, construed the Upaniṣadic slogan "Brahman = Atman" as the "closest thing to the truth." However, the historical and philosophical literature on his engagement with Indian ideas remains limited and often confused. Two questions should be addressed for a more comprehensive account of Schrödinger's philosophical views: which Indian insights did he embrace, and what was their role in his thought? I argue that examining what he termed the Indian "doctrine of identity" illuminates answers to these questions and can correct some historical misinterpretations. First, situating Schrödinger's reading of Indian works in his time and analyzing his personal notebooks reveals the dominance of Śaṅkara's Advaita Vedānta reading of the Upaniṣads. Second, by analyzing Schrödinger's published writings and personal notebooks, I argue that this doctrine of identity offered Schrödinger religious consolation, but, furthermore, that Schrödinger took these Indian ideas seriously in his philosophy as well. I highlight how Schrödinger adopted this doctrine of identity into his metaphysical ruminations about the nature of reality and show how it resonates with some of his reflections in the philosophy of science.

The oil and uranium industries always have been intertwined. Both industries are inherently global and span an extensive geological history. The formation of uranium and oil deposits, and their eventual extraction, is a story circling through early planetary history, continuing in depleted oil wells in Germany, Canada, and France, and lingering well into the second half of the past century. Understanding this history proved to be the key for two businesses that would shape the later twentieth century: the oil and nuclear industries. Oil companies are among the very first to integrate new quantum mechanics and knowledge about radioactive decay into their search for oil. This article locates the origins of this interconnectedness in the emergence of applied geophysics. Based on case studies to the experiments and research projects of geophysicist Richard Ambronn and the studies by the oil service company Schlumberger into measuring radioactive decay as a method of determining underground sediments and finding oil during the 1920s and 1930s, this article argues that the depleted oil sources at Pechelbronn and Celle formed the basis of both industrial and academic developments in the knowledge of radioactivity, geophysics, and petroleum.

This special issue presents six research papers that were developed within the Taiwanese-German working group "Materialities of Medical Cultures in/between Europe and East Asia." Our working group uses the concept of "in/between" as an umbrella term to study the cultural history of drugs and the practices of medicine and care. This issue's articles address the question of how drugs and medical knowledge emerged from the various in/between spaces created by encounters between East Asian and European medical cultures. Their focus is on the entanglements of matters and knowledge in the contexts of mission and colonialism, the production of medicinal substances and helminthology, as well as on premodern knowledge cultures concerning childbirth and the preparation and consumption of animals with a medicinal background. The contributions present a comparative perspective on material and knowledge cultures surrounding medical materials from plants, animals, and humans. In this introduction, we summarize the discussions within our Taiwan-German working group as case studies on how scholars of East Asian and European studies can meet under the "in/between" umbrella term as a productive approach to an interdisciplinary and comparative history of knowledge.

This paper was prompted by some striking similarities between both the ritual and the medical use of placenta in Ming China and in premodern Europe. Contrary to most accounts, which focus either on the rise of chemiatric medicine or on the growing interest in "exotic" substances, the seventeenth century in Europe also reveals a revived interest in substances from animals, including materials from human bodies. The paper will analyse the use of words signifying the placenta, and follow the trace of vernacular knowledge about the placenta and its role in birth-giving, and in medieval medical texts on women's medicine. I will then analyse how the placenta is treated in systems of signatures in the age of alchemy and will try to trace the advent of more complicated preparations in the seventeenth century, and how between the eighteenth and the twenty-first century, the placenta meandered between a token of folk medicine (re)productive material and pharmaceutical resource.

Humans and donkeys have had a closely interactive relationship throughout history, despite being two completely different species. How has Chinese society viewed the donkey in its long history? How have donkeys been used? And what kind of boundaries do people place on the donkey? This study has focused on the consumption of donkey in Chinese history from medical, cultural and legal aspects. All in all, considering food, medicine, and legal viewpoints, from the medieval period to the Qing Dynasty (1644-1911), the question whether or not one should consume donkey depended on its characteristics, taste, texture, and the side effects, as well as whether the manner of consumption is consistent with social moral standards and its derived legal boundary issues.
