As an image-making tool for scientists studying the transient, instantaneous photography has long been seen as opening up a visual realm previously inaccessible to the inferior testimony of the human eye. But when photographic pioneer Henry Fox Talbot took the first photograph of a moving object by the light of an electric spark in 1851, he was guided by existing visual practices designed to create instantaneous vision in the eye itself. Exploring the background behind the peculiar subject of his experiment - a mechanically spinning disc - reveals a hidden prehistory of spark-illuminated photography: physicists' pre-photographic techniques for stopping time. 相似文献

Alchemy is part of the cultural experience of early modern Europe and yet has had to overcome problems of demarcation to be considered relevant to the history of science. This essay considers historiographical and methodological issues that have affected the gradual demarginalization of alchemy among attempts to explain, and find things out about, nature. As an area of historical study, alchemy relates to the history of science as part of an ensemble of practices that explored the natural world through natural philosophy and speculative traditions and by functioning as a nexus of social and intellectual life. 相似文献
