An der Schwelle zum Atomzeitalter. Die Vorgeschichte der Entdeckung der Kernspaltung im Dezember 1938

On the Threshold of the Atomic Age: The History of the Discovery of Nuclear Fission in December 1938: - Fifty years ago in mid-December 1938, Otto Hahn and Fritz Strassmann at the Kaiser Wilhelm Institute of Chemistry discovered nuclear fission by demonstrating, using chemical methods, the presence of barium in the decay products of neutron-irradiated uranium. This essay points out the constellation of conditions and prerequisites (Historischer Erfahrungsraum/“historical field of experience”) which led to the discovery of nuclear fission, and was constituted by specific components (“presentabilia”) both internal and external to science in general and to atomic research in particular. A decisive role was played by the constellation of the three members of the Berlin team and their personal situations under the political conditions of the 1930s. Further “presentabilia” were the institutional, instrumental and disciplinary conditions under which the team worked and the methods available to the individual members of the team. It was very important that some of the “presentabilia” were “not-present” to the members of the team. In particular, after Meitner's departure from Berlin Hahn and Strassmann had no access to methods and tools for proving the presence of alpha rays; nothing was known of the existence of actinides; no cyclotron or other source of neutrons more productive than those already in use in Berlin, Paris and Rome was available; it was very important that Strassmann and Hahn were not convinced of the strong validity of the resonance process induced by thermal neutrons; etc.

Das Wissen der Schulden. Recht,Kulturtechnik und Alltagserfahrung im liberalen Kapitalismus

The Knowledge of Debt: Law, Media Technique, and Everyday Experience in Liberal Capitalism. Performing an object such as ‘the economy’ hinges on practices of formatting knowledge. The article proposes to look at such instituting moments in connection with social conflicts over the legitimate rules of exchange. This is exemplified by way of recounting the story of the codification of Swiss bankruptcy law in 1889. In order to homogenize the legal procedures of debt collection and bankruptcy, two subject categories were instituted: ‘merchants’ and ‘non-merchants’. These different categories were thought to account for the diverging temporalities and spaces of credit exchange in everyday economic life. The introduction of the commercial register, a media-technical apparatus, enabled a formal distinction between ‘merchants’ and ‘non-merchants’. However, this boundary was contested and proved to be porose.     

Science With a Difference: Parody and Paradise in Margaret Cavendish's The Blazing World (1666)

Wissenschaft mit Unterschieden: Parodie und Paradies in Margaret Cavendishs The Blazing World (1666) . Mit ihrer utopischen Erzählung The Blazing World (1666) ist Margaret Cavendish, Duchess of Newcastle, eine der wenigen Autorinnen der Frühen Neuzeit, die sich sowohl im Feld der Literatur als auch der Naturphilosophie betätigten. Auf den ersten Blick scheint die Welt jenseits des Nordpols, in die die Protagonistin nach gewaltsamer Entführung und Schiffbruch gerät, ein weibliches Wissenschaftsparadies: Nach eilig erfolgter Vermählung mit dem Kaiser regiert sie eigenverantwortlich über die wissenschaftlichen Institutionen ihres Reichs und debattiert mit Bären-, Vogel-, Wurmmännern und ähnlichen Hybridwesen über die neuesten wissenschaftlichen Errungenschaften. Bald schon stellt sich jedoch heraus, dass ihre „Wissenschaftler“ denjenigen der englischen Realität sowohl in ihrer blinden Begeisterung für neue Forschungsinstrumente wie in ihrem ermüdenden Austausch von Meinungen und Glaubenssätzen durchaus ähnlich sind. Unterstützung für ihre Kritik und für eigene Forschungs- und Schreibprojekte findet die Protagonistin in der Autorin selbst, der Duchess of Newcastle, in deren Welten sich die beiden gemeinsam begeben. Parodie und Satire, die auf zeitgenössische Modetorheiten im Umfeld der Royal Society abzielen, stehen im Fokus des vorliegenden Aufsatzes ebenso wie utopische Perspektiven, die durch die Eröffnung neuer Denkräume entstehen. Auf dem von ironisch kommentierten Fetischen und Hybriderscheinungen gepflasterten Weg dorthin bewegt sich die Erzählung zwischen Realität und Virtualität, Fakten und Fiktionen, kritisiert epistemologische und institutionelle Vorgaben und testet die Grenzen der Geschlechter im neu entstehenden Feld von Wissenschaft und Literatur. Summary : Science With a Difference: Parody and Paradise in Margaret Cavendish's The Blazing World (1666) . Margaret Cavendish's The Blazing World (1666) is one of the very few utopian accounts by women in the early modern period. At first sight, the world beyond the North Pole that Cavendish's beautiful heroine enters after surviving abduction and shipwreck seems to offer the utmost in terms of early modern feminine scientific utopias: after the shortest love story in history, the heroine becomes Empress and is given a whole Empire to govern at her pleasure. But soon it turns out that the hybrid creatures of her newly founded scientific communities, bear-men, bird-men, worm-men, and the like are far from utopian truth-seeking, but, like their earthly counterparts, all too often revel in tedious meaning and believing. The paper will focus on such parodic moments as well as on alternative modes of dealing with science more adequate to the term Paradise. Only with the support of her this-worldly friend, the Duchess of Newcastle, who also happens to be the author of the story, the Empress can not only improve her utopian state, but also the state of affairs in the real world. On the way, the boundaries between fact and fiction, real and virtual, masculine and feminine, sense and nonsense are continuously tested – reflecting and commenting on early modern fear and fascination of the unknown and the promises of science and technology.
