Präzision versus Exaktheit: Konfligierende Ideale der angewandten mathematischen Forschung: Das Beispiel der Tragflügeltheorie

It is often supposed that mathematical argument provides a model of precision for the sciences. In contrast to this view, the present article proposes to distinguish between mathematical exactness as a (historically variable) ideal regulating the inner standards of mathematical argumentation and precision as a (historically variable) norm governing the relation between products of mathematical reasoning in scientific contexts and empirical or practical data. By discussing a major achievement in the mathematization of flight, Ludwig Prandtl's lifting line theory of wings, it is shown that exact reasoning does not necessarily lead to scientific precision, and that the achievement of precision may even require to loosen existing standards of exactness. It is argued that the main contribution of mathematical argument to generating precision in science lies in its capacity to provide sophisticated tools for the production of data, rather than in its adherence to an ideal of exactness.     

Natur-Wissenschaft und Gotteserkenntnis: Das jüdische Modell

The thesis proposed here is that in Judaism creation is seen as a unique act of God at a specific point in time. In medieval philosophy the act of creation is interpreted as natural science, which concerns itself only with products of divine creation. This is contrasted with theology, which is concerned not with creation but with God. Francis Bacon takes this model from Moses Maimonides for his work Nova Atlantis. Natural science replaces theological studies for Bacon.     

Vom Nationalsozialismus vertriebene Wissenschaftler auf dem Markt. Die Arbeitsvermittlung des englischen Academic Assistance Council (SPSL) am Beispiel von Türkeiemigranten

After 1933 many scientists and university teachers were obliged to relinquish their posts in the universities of Germany because of national-socialist laws. Organizations-in-aid like the Academic Assistance Council in Great Britain tried to ‘defend science and learning’ raising funds and finding new openings for the expelled academics. But as immigration laws were tight and jobs were scarce in the host countries the AAC and the other organizations had to select the most qualified from among the applicants for support. – The questions the article tries to answer are: What kind of criteria were applied in this selection? Who were the experts? How were the placements made? How did the applicants react to the decisions? Taking for example the AAC, it examines measures to assist a group of scientists who, having tried to settle down in England, finally emigrated to Turkey.     

Briefe im 19. Jahrhundert als wissenschaftshistorische Quelle. Dargestellt am Beispiel des Briefwechsels des Apothekers A. P. J. Du Menil (1777–1852)

The aim of this article is to demonstrate the importance of scientific communication of pharmacists in the 19th century. 89 letters were analysed both written received by August Peter Julius Du Menil (1777–1852). In the paper also a summary is given about the importance of extensive activity of the pharmacist Du Menil. He was be in correspondence with 39 scientists, for instance 13 physicans and 12 pharmacists. The letters are an interesting document about scientific community in the 19th century.     

Disziplinerneuerung und Universitätsreform: Das Ius publicum Romano Germanicum

What caused the reforms which permitted the universities in the Holy Roman Empire to become leading places of scientific communication and mental orientation for centuries? In most cases, outside influences - pressures from governments, princes, scholars, councillors, consistories, or, as we would say today, state and churches - were decisive. But some reforms were the consequences of paradigm-changes within the universities themselves. Such shifts were less likely to originate with faculties concerned with medicine or the natural sciences than with those which were concerned directly with the political community or human societies. This changed only in the nineteenth century, which cannot be dealt with here.
