RésuméLes observatoires occidentaux se transforment en véritable usine scientifique à partir du milieu du 19e siècle. L'astrométrie symbolise ce passage à une économie industrieuse des pratiques scientifiques. Le chronographe imprimant, qui permet de réduire les équations personnelles des observateurs, s'impose, d'abord aux Etats-Unis, puis en Angleterre, en instrument-emblème de cette transformation profonde. En France, les initiatives de l'astronome Liais restent prototypiques. Ce n'est qu'au début du 20e siècle, par les voies détournées de l'observatoire d'Hendaye et de l'abbé Verschaffel, que le (...) chronographe imprimant fait son retour et conquiert les espaces savants. La centralisation excessive de l'astronomie française, l'autoritarisme du directeur de l'Observatoire de Paris Urbain Le Verrier, et la faiblesse du marché des instruments expliquent pourquoi le chronographe imprimant n'a fait souche que très tardivement en France.

According to Hugo Münsterberg, the direct application of experimental psychology to the practical problems of education, law, industry, and art belonged by definition to the domain of psychotechnics. Whether in the form of pedagogical prescription, interrogation technique, hiring practice, or aesthetic principle, the psychotechnical method implied bringing the psychological laboratory to bear on everyday life. There were, however, significant pitfalls to leaving behind the putative purity of the early psychological laboratory in pursuit of technological utility. In the Vocation Bureau, for (...) example, psychological instruments were often deemed too intimidating for a public unfamiliar with the inner workings of experimental science. Similarly, when psychotechnical means were employed by big business in screening job candidates, ethical red flags were raised about this new alliance between science and capital. This tension was particularly evident in Münsterberg's collaboration with the Paramount Pictures Corporation in 1916. In translating psychological tests into short experimental films, Münsterberg not only envisioned a new mass medium for the dissemination of psychotechnics, but a means by which to initiate the masses into the culture of experimental psychology.

To those not engaged in the practice of scientific research, or telling the story of this enterprise, the image of empirical observation may conjure up images of boredom more than anything else. Yet surprisingly, the profoundly uninteresting nature of research to many science workers and readers in history has received little attention. This paper seeks to examine one moment of encroaching boredom: nineteenth-century positional astronomy as practised at leading observatories. Though possibly a coincidence, this new form of astronomical observation arose (...) only a few decades before the English term ‘boredom’, for which theOxford English Dictionaryhas no record prior to 1850. Through examining forms of observatory labour and publications, I offer in this paper an example of how boring work and reading helped shape a scientific discipline. (shrink)

ArgumentThe discovery of the Alps in the second half of the eighteenth century spawned an aesthetics of sublimity that enabled overwhelmed beholders of mountains to overcome their confusion symbolically by transforming initial speechlessness into pictures and words. When travelers ceased to be content with beholding mountains, however, and began climbing them, the sublime shudder turned into something else. In the snowy heights, all attempts to master symbolically the challenging landscape was thwarted by vertigo, somnolence, and fatigue. After 1850, physiologists intervened, (...) using the Alpine terrain as a laboratory landscape that was ideally suited to examine one of the most threatening concerns offin de siècleindustrial societies: fatigue. This essay examines how the picturesque voyage turned into an experimental physiology of fatigue, and how the “wordless subjectivity” of romantic travelers turned into the “wordless objectivity” of life scientists.

This paper presents the data gathering of Matthew Fontine Maury at the U.S. Naval Observatory as pushing an epistemic boundary outside traditional laboratory walls. Maury's use and control of civilian navigators explicates the development of an astronomic epistemology deeply embedded in nineteenth century American society. In conclusion, following the movement of epistemic boundaries is offered as a guide to crucial moments in the development of a multifaceted modernity.

Often the truth value of a scientific claim is dependent on our faith that laboratory experiments can model nature. When the nature that you are modelling is something as large as the tallest terrestrial mountain on earth, and as mysterious as the reaction of the human body to the highest point on the earth's surface, mapping between laboratory and ‘real world’ is a tricky process. The so-called ‘death zone’ of Mount Everest is a liminal space; a change in weather could (...) make the difference between a survivable mountaintop and a site where the human respiratory system cannot maintain basic biological functions. Predicting what would happen to the first human beings to climb that high was therefore literally a matter of life or death – here inaccurate models could kill. Consequently, high-altitude respiratory physiology has prioritized not the laboratory, but the field. A holistic, environmentally situated sort of science used a range of expertise to prove the laboratory wrong time after time. In so doing, Everest was constructed paradoxically both as a unique field site which needed to be studied in vivo, and as a ‘natural laboratory’ which could produce generalizable knowledge about the human body.

The 'Reaction experiment with Hipp chronoscope' is one of the classical experiments of modern psychology. This paper investigates the technological contexts of this experiment. It argues that the development of time measurement and communication in other areas of science and technology (astronomy, the clock industry) were decisive for shaping the material culture of experimental in psychology. The chronoscope was constructed by Matthaus Hipp (1813-1893) in the late 1840s. In 1861, Adolphe Hirsch (1830-1901) introduced the chronoscope for measuring the 'physiological time' (...) of astronomical observers. Hirsch's observatory at Neuchatel (Switzerland) served to control the quality of clocks produced in the nearby Jura mountains. Hipp provided the observatory with a telegraphic system that sent time signals to the centers of clock production. Time telegraphy constituted the stable surroundings of the reaction time experiments carried out by both astronomers and psychologists. This technology permitted precise measurements of short time intervals and offered to Hirsch, as well as to Wilhelm Wundt (1832-1920), a useful metaphor for conceptualizing their respective 'epistemic objects'. But time telegraphy also limited the possibilities of the experimental work conducted within its framework. In particular, noise from outside and inside the research sites at Neuchatel, Leipzig and elsewhere disturbed the precise communication of time. (shrink)

This paper argues for continuity in purpose and specific results between some hand drawn nebulae, especially those ‘descriptive maps’ by John F. W. Herschel and E. P. Mason in the late 1830s, and the first photographs made of the nebulae in the 1880s. Using H. H. Turners’ explication in 1904 of the three great advantages of astrophotography, the paper concludes that to some extent Herschel’s and Mason’s hand-drawings of the nebulae were meant to achieve the same kinds of results. This (...) is surprising not only because such drawings were conceived and achieved over forty-years earlier, but also because the procedures used in the production of these pictorially and metrically rich images were those directly inspired by cartography, geodesy, and land-surveying. Such drawings provided the standard for what was depicted, expected and aimed at by way of successful representations of the nebulae; standards that seemed to have been used to judge the success of nebular photographs. Being conditions of expectation and possibility for later photography, these drawings were themselves made possible by such techniques of representation and measurement as isolines and triangulation, so fundamental to Imperial and ‘Humboltian science.’Keywords: Ebenezer Porter Mason; Cartography; Draughtsmanship; Observation; Scientific Representation; Philosophy of Scientific Practice.
