Archaeology, like most sciences that rely on stratigraphic excavation for studying the past, tends to conceptualize this past as lying deep underneath the ground. Accordingly, chronologies tend to be depicted as a movement from bottom to top, which contrast with sciences that illustrate the passage of time horizontally. By paying attention to the development of the visual language of disciplines that follow stratigraphy, I show how chronologies get entangled with other temporalities, particularly those of writing. Relying on recent ethnographic work (...) with archaeologists, the analysis reveals that excavation emerges as a double vertical movement of downward destruction and upward reconstruction that coincides with a systematic dissociation of time and space that has important effects for the understanding of the formation of sites. I conclude by looking at some of the implications of this dissociation for contemporary theoretical discussions, particularly those that emerged after the phenomenological push to horizontalize the discipline. Challenging this dissociation, I argue that the conceptualization of time in science should be understood as a process that depends on the body and unfolds in movement. (shrink)

This paper explores the history of radio echo-sounding , a technique of glaciological surveying that from the late 1960s has been used to examine Antarctica's sub-glacial morphology. Although the origins of RES can be traced back to two accidental findings, its development relied upon the establishment of new geopolitical conditions, which in the 1960s typified Antarctica as a continent devoted to scientific exploration. These conditions extended the influence of prominent glaciologists promoting RES and helped them gather sufficient support to test (...) its efficiency. The organization and implementation of a large-scale research programme of RES in Antarctica followed these developments. The paper also examines the deployment of RES in Antarctic explorations, showing that its completion depended on the availability of technological systems of which RES was an integral part. (shrink)

History of science's spatial turn has focused on the horizontal dimension, leaving the role of the vertical mostly unexplored as both a condition and object of scientific knowledge production. This special issue seeks to contribute to a burgeoning discussion on the role of verticality in modern sciences, building upon a wider interdisciplinary debate about the importance of the vertical and the volumetric in the making of modern lifeworlds. In this essay and in the contributions that follow, verticality appears as a (...) condition of knowledge production—a set of movements and mobilities, technical challenges, political negotiations, and bodily hardships—and an object of scientific inquiry, requiring new techniques of mapping and visualisation and generative of new insights into physical processes and temporal change. By foregrounding the vertical, historians of science can gain new insights and tell new stories about how science is done in the field, the observatory, and the laboratory, and about how those sciences have helped build a modern, three-dimensional world.

Translation abstractZusammenfassung: Daten, Modelle und Erdgeschichte ineinander gefaltet: Paläo‐ Simulationen und ihre epistemologische Unruhe. Klima‐ und Erdsystemmodelle werden nicht nur verwendet, um künftige klimatische Bedingungen zu prognostizieren, sondern auch, um vergangene Klima‐Ereignisse zu rekonstruieren. Dieser Beitrag ist der zweite in einer Reihe, welche die Paläoklimatologie – die Wissenschaft der Klimate vor Anbeginn direkter, instrumentenbasierter Messungen – als eine epistemisch radikale Praxis vorstellt, die in direkter und offener Weise die Unterscheidung zwischen Daten und Modell aufhebt sowie den Begriff des Experiments rekonfiguriert (...) und im Zuge dessen unsere Vorstellungen einer tiefen, d. h. geologischen, und einer flachen, d. h. historischen Zeit miteinander vermengt. Der vorliegende Artikel zeigt erstens, wie sich im Zuge der Einführung von General Circulation Models nicht nur die Wissensproduktion über die komplexen Ursachen und Abläufe früherer Klimawandel‐Ereignisse auf numerische Simulationen verlagerte, sondern diese Einführung selbst von paläoklimatologischen Fragen begleitet, wenn nicht gar eminent beeinflusst wurde. Zweitens erweisen sich die numerischen Experimente inzwischen als potente Katalysatoren eines neuen Verständnisses für die spezifische Zeitlichkeit, in der sich unsere Gegenwart im Übergang zum Anthropozän entfaltet. In der Diskussion der historischen Entwicklung der Paläoklimamodellierung und durch die Untersuchung der produktiven heuristischen Eigenschaften ihrer Praxis stellt der Artikel unsere Fixierung auf die Kategorie der Unsicherheit infrage.

An early example is von Neumann's and Charney's Princeton Meteorological Project in the period 1946–53 which ended with daily numerical prediction in less than 2 hours. After this stage, the questions of long-range forecasting and general circulation of the atmosphere became of greater importance. The late 1950s saw the emergence of an alternative: were atmospheric models used mainly for prediction or understanding? This controversial debate in particular occurred during an important colloquium in Tokyo in 1960 which gathered together J. Charney, (...) E. Lorenz, A. Eliassen, and B. Saltzman, among others, and witnessed discussions on statistical methods for predictions and/or maximum simplification of dynamic equations. This phase ended in 1963 with Lorenzs seminal paper on “Deterministic non periodic flows.”. (shrink)

In the early exploration and colonization of the Americas, Europeans encountered unfamiliar climates that challenged received ideas from classical geography. This experience drove innovative efforts to understand and explain patterns of weather and seasons in the New World. A close examination of three climatic puzzles (the habitability of the tropics, debates on the likelihood of a Northwest Passage, and the unexpectedly harsh weather in the first North American colonies) illustrates how sixteenth- and seventeenth-century observers made three intellectual breakthroughs: conceiving of (...) climates as a distinct subject of inquiry, crossing the hitherto-separated disciplines of geography and meteorology, and developing new theories regarding the influence of prevailing winds on patterns of weather and seasons. While unquantified and unsystematic, these novel approaches promoted a new understanding of climates critical to the emergence of climate science. This study offers new insights into the foundations of climatology and the role of the New World in early modern science. (shrink)
