The ArgumentIt is often assumed that all sciences travel the path of increasing precision and quantification. It is also assumed that such processes transcend the boundaries of rival scientific disciplines. The history of the personal equation has been cited as an example: the “personal equation” was the name given by astronomers after Bessel to the differences in measured transit times recorded by observers in the same situation. Later in the nineteenth century Wilhelm Wundt used this phenomenon as a type for (...) his experiments on reaction times. For historians of psychology, this has been taken to be an exemplary case where quantified laboratory science rescued astronomy by showing that this was really a psychological phenomenon measurable only in complication experiments. This paper challenges this story. Astronomers neither ignored, nor despaired of, the personality problem. Instead, the managers of the great observatories developed a new chronometric regime of vigilant surveillance of subordinate observers. The astronomers' solution was thus intimately connected with social and material changes in their way of life: a division of labor in the observatories, a network of observing sites, a mechanization of observation. The paper documents these changes and then presents a study of one case where managers, amateurs, and psychologists clashed for authority over the personality problem. Measurement is given its meaning when situated in specific contexts of styles of work and institutions. Disciplines give meanings to values, and often resist attempts by others to redefine these meanings or to gain authority over measurement. Quantification is not a self-evident nor inevitable process in science's history, but possesses a remarkable cultural history of its own. (shrink)

ABSTRACT While historical studies of “popular science,” variously conceived, have grown in number and sophistication, they have sometimes seemed marginal to the discipline. James Secord's recent call to reintegrate the histories of both science popularization and science in popular culture within a more comprehensive history of “knowledge in transit” promises to overcome this marginalization. At the same time, however, Secord suggests that “popular science” should be abandoned as a “neutral descriptive term” because it is historically freighted, not least with “diffusionist (...) baggage.” This Focus section explores the historical and historiographical implications of abandoning an essentialist definition of “popular science” and of examining instead its complex and varied history as an actors' category during the last two centuries. The essays emphasize the importance of transnational and interdisciplinary perspectives in exploring the very diverse ways in which the discourses and practices of “popular science” have been employed. In addition, they consider the implications of the modernity of such discourses and practices for the history of science in the longue durée. (shrink)

This survey outlines a history of museums written through biographies of objects in their collections. First, the mechanics of the movement of things and the accompanying shifts in status are considered, from manufacture or growth through collecting and exchange to the museum. Objects gathered meanings through associations with people they encountered on their way to the collection, thus linking the history of museums to broader scientific and civic cultures. Next, the essay addresses the use of items once they joined a (...) collection, whether classificatory, analytical, or in display. By thus embedding the study of scientific practice in material culture, this approach contributes to constructivist histories of science. The final section addresses the role of objects in the experience of the visitors, emphasizing how fruitful the history of museum objects can be in the study of the public engagement with science.

Because Francis Galton (1822-1911) was a well-connected gentleman scientist with substantial private means, the importance of the role he played in the professionalization of the Victorian life-sciences has been considered anomalous. In contrast to the X-clubbers, he did not seem to have any personal need for the reforms his Darwinist colleagues were advocating. Nor for making common cause with individuals haling from social strata clearly inferior to his own. However, in this paper I argue that Galton quite realistically discerned in (...) the reforming endeavors of the 1860s, and beyond, the potential for considerably enhancing his own reputation and standing within both the scientific community and the broader Victorian culture. In addition, his professionalizing aspirations, and those of his reformist allies, were fully concordant with the interests, ambitions and perceived opportunities of his elite social group during the Victorian period. Professionalization appealed to gentlemen of Galton's status and financial security as much as it did to the likes of Thomas Huxley and John Tyndall, primarily because it promised to confer on the whole scientific enterprise an unprecedented level of social prestige.
