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.

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.

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.

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.

The Western world has a profound historical engagement with medicinal resources originating from China. Following the Opium War, missionaries were granted access to China and established residence there. Motivated by clinical necessities and the inquisitiveness of the Western scientific community, these missionaries meticulously documented the medicinal resources available in China, endeavoring to incorporate this knowledge into Western pharmacology. Among the various reports produced in multiple languages, the contributions in English have emerged as particularly influential. This article seeks to analyze the information-gathering processes within the missionary network and among other naturalists, commencing with Robert Morrison, the inaugural compiler of the English-Chinese dictionary, and extending to Stephen A. Hunter, who collaborated with Chinese officials to develop a complete translation for pharmaceutical nomenclature.

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.

Before World War II, Taiwan became the second-largest coca leaf production base in Asia, second only to Java, contributing to Japan's position as the world's largest exporter of cocaine. While Japan's opium empire has been the subject of extensive academic inquiry, its coca empire has received far less attention. This article explores Taiwan's role in Japan's dual empire of opium and coca, focusing on the environmental and historical factors that enabled the island to rapidly expand coca production. It finds that, in addition to Taiwan's favorable climate for coca cultivation, the island's long-established tea industry provided mature techniques for harvesting and drying the coca leaves. Furthermore, the sugar company supplied the necessary equipment and capital for the extraction of cocaine, becoming a key resource in the industry's development. Learning from the limitations of the opium monopoly—where raw materials were increasingly constrained by international markets—the colonial government sought to promote self-sufficiency in coca production. This strategy not only ensured a stable supply of raw materials but also allowed the coca industry to balance for the declining incomes from opium as international controls tightened. From all angles, the coca industry met Japan's expectations as a “promising drug.”
