Spekulation und Physik im 18. Jahrhundert. Lomonossow,Kant und Lavoisier in Sachen Erhaltungsgesetz und Äther

As far as the law of preservation of matter and the existence of ether are concerned, Kant, Lomonossow and Lavoisier had very similar views. Nevertheless, according to historical evidence they worked out their theories never taking each other's results for granted. Whereas it is well known that Lavoisier did not base his experiments on the former ones by Lomonossow, it has been argued that Kant based his philosophy of nature on Lavoisier's experiments. I try to show here, that Kant had his philosophy of nature done, prior to Lavoisier's Elements of Chemistry. Further that the only one to have been able to influence Kant was not Lavoisier but Lomonossow. But Kant never mentioned Lomonossow. There is strong evidence that the similarity of views in Kant, Lomonossow and Lavoisier is not due to any kind of interaction between them. This also holds of the (same) mistakes, which Kant and Lomonossow made. The only substantial difference is that Kant thought, that some laws of nature may be logically inferred without experiments.

Physik und Politik in der frühen Bundesrepublik Deutschland. Max Born,Werner Heisenberg und Pascual Jordan als politische Grenzgänger

Physics and Politics in the Early Federal Republic of Germany. Max Born, Werner Heisenberg and Pascual Jordan between Scientific and Political Discourse. – Contrasting the historiography of two major developments in 20th century German history, the creation of quantum mechanics in 1925 and the dispute on the nuclear armament of the Federal Republic of Germany in 1957, the question is raised to which extent the scientific culture was able to bridge political disagreement within the German physicists' community. A twofold story of the private and public exchange between Max Born, Werner Heisenberg and Pascual Jordan among others on the scientists' position to nuclear armament on the one hand and the writing of the history of quantum mechanics on the other hand displays different types of relating scientific work and moral responsibility. Neither politics nor science went on unaltered after the disputes between physics and politics in the early Federal Republic of Germany.     

Deutsch-italienische Wissenschaftsbeziehungen im 18. und 19. Jahrhundert — Dimensionen und Perspektiven

The scientific interrelationships between Italy and Germany in the 18th and 19th centuries — a hitherto neglected area of research — are discussed in an overview according to the following ten dimensions: language knowledge and translations; reviews and bibliographies; library content; personal contents and correspondance; travel reports and travel guides; diaries and autobiographies; university studies and research sojourns; membership in academies and scientific societies; practical and theoretical resonance; comparisons to other countries. This approach, which has to be concretized in future studies, promises at the same time general insights into the logic of science and its progress.
