Die Emigration der Kulturwissenschaftlichen Bibliothek Warburg und die Anfänge des Universitätsfaches Kunstgeschichte in Großbritannien

Aby M. Warburg (1866- 1929) the famous art historian, critic and great promoter of cultural history collected a unique research library which became a semiofficial part of the newly founded University of Hamburg called ?Kulturwissenschaftliche Bibliothek Warburg”? in 1920. At the end of 1933 this library and its staff left Germany in order to prevent the Nazis from destroying this Jewish foundation. Great Britain gave home to it and at the end of 1944 London University incorporated the library now named The Warburg Institute. The Warburg Institute efficiently helped to promote art history as an academic discipline in Great Britain though its actual aims are of interdisciplinary nature and go far beyond art history as it has been the case since the days of Warburg.     

Erfahrung und Vorurteil im naturwissenschaftlichen Denken Johannes Keplers

The change from ancient and medieval to modern natural science, called Wende (instead of ‘revolution’), must be associated with the work of Johannes Kepler and not that of Nicolaus Copernicus. Copernicus merely showed the way, introducing heliocentricity as the order of the planets. This Wende resulted from the synthesis of several disciplines formerly isolated from each other, namely mathematical (i.e. hypothetical) astronomy, new physics, mathematical harmony, astrology, new physical optics, and natural theology. Whereas Copernicus united mathematical astronomy and peripatetic (Aristotelian) physics, Kepler was first to see the necessity for providing a physical explanation and an ontological foundation to the heliocentric system. He was the first to consider and measure the movement of the planets in depth. The elements for his new physics Kepler obtained not from newly observed data, but from a harmonic archetypus of the regular polyhedra fitted in between excentric planetary spheres. On the basis of this archetypus (which he considered to be God's model in creating the universe) he accepted the new heliocentric planetary system as a physical reality. That is why astronomy, by way of taking into account stereometric quantities, is, in Kepler's eyes, a kind of divine worship. Later, the best empirical data had also to be taken into consideration as a means of proving this a priori archetypus (Vorurteil, preconception). The result was, on the one hand, a universal natural science able to explain natural processes in grater abundance than ever before or since in the history of science. Although accepted only in parts, it resulted in founding a new natural science with adherent mathematical and empirical methods. It also led Kepler to establish, step by step, the elliptical path of the planets, thereby overcoming, for the first time, the two axioms of ancient astronomy, requiring uniform and circular planetary motion. It has been shown that this Keplerian Wende was possible only within the Historischen Erfahrungsraum (‘historical field of experience’) of Renaissance Humanism (cf. this Journal 9/1986, p. 201), which came about itself as the result of reactivating the scientific and philosophical thinking of the ancient Greeks and was accomplished by three steps (phases) relating to the revival of (1) original ancient writings, (2) the ancient knowledge of natural facts and data, and (3) the ancient scientific and philosophical ideas and mentalities (Drei-Phasen-Modell).     

Erfahrung,Weltbild und Erkenntnis bei Nikolaus Cusanus

To explain the interaction of stillness and motion of thought, Nicholas Cusanus formulated his renowned comparison with a cosmographer, which through five gateways, corresponding to the five senses, receives information about the world in the form of messages. What follows therefrom is not directly an analysis of the world but of the Creator, whom the philosopher mirrors in himself as a creator of scientific symbols. Cusanus was repeatedly suspected of Pantheism. What is crucial, however, for the critique of reasonning is the parallelism, that God's omnipresence in his creation corresponds to a universal capacity of the human mind to perceive everything by means of a hypothetical otherness (alteritate coniecturali). Therefrom proceeds the general projection that everything can be seen in mathematical terms. Mathematical calculating, working with figures, reducing to units, leads Cusanus to God's creative power as much as to the functioning of the intellect. However, his renowned mental experiments on the minimum and maximum were purely in pursuit of the goal of describing the fluid frontiers of defined thought. This is also true of his cosmology. Cusanus argued mathematically in order to prove the non-mathematical and the non-realistic.     

Die Pansophie des Comenius und der Baconismus der Royal Society

The specific comprehension of the subject of the modern times in the 17th century articulates itself in the pretension to be the master of the world of nature and human beings. This pretension, however, was not longer legitimated in a theological or biblical argumentation, but with the philosophical hint on a special qualification of the human being: knowledge and science. In this view, the philosophical reflections of Francis Bacon of Verulam, which were culminating in the well-known judgement of the coincidence of knowledge and power, became the very important philosophy of science of the most prominent academy of sciences in the 17th century: The Royal Society of London. This “Baconism” distincted himself strictly from all questions belonging to religion, politics, social or moral problems. This distinction was the reason for its opposition to the “Pansophie” of Johann Amos Comenius, whose main intention was the general reformation of the whole world, including a reform of science, religion and politics. The insistence of Comenius for the social responsibility of science is still up-to-date.     

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.     

Einfluß der Chemischen Industrie auf den Chemieunterricht Abriß einer historischen Entwicklung

This historical inquiry into the enfluence with the Chemical Industriy and the chemistry education at German classical stateschools is described since the revolution of 1848. The introduction of chemistry lessons at German classical stateschools step by step is further observed between 1882 and 1901. Specially the author gives a comprehensive survey about the development after the World War II.     

Arbeit und Zeit,Körper und Uhr: Die Konstruktion von ‚effektiver’︁ Arbeit im ‚Scientific Management’︁ des frühen 20. Jahrhunderts

The concept ‚Scientific Management’︁ was invented in 1910 for what was then called the ‚Taylor‐system’︁ of shop management. Frederick W. Taylor had developed his system to eliminate the “waste of human effort” mainly by “time study”, the analysis of the work of “first‐class workman” with a stop‐watch and the synthesis of standard times for given tasks which make the “waste” of effort visible and measurable. A reading of Karl Marx's work shows the “paradigm of productivity” governing mid‐century discussion of the value of labor. Time is a central element in the valuation of industrial labour, but only with Taylor the precision of the stop‐watch is introduced to observe and control the productivity of the body of the worker. As disciples of Taylor Frank and Lillian Gilbreth introduced motion studies and micromotion studies into Scientific Management. Their analysis of the motion of workers, technically assisted by high‐speed watches and cameras, goes beyond the surface‐observation of the first‐class workman to enable the design of efficient motion. The body of the worker is represented in lines of light and tables of data. The objects of desire are the time‐lines of efficiency and productivity. In both cases, Taylor and the Gilbreths, various observations further lead to the conclusion that science and schooling are an important historical background to the rise of Scientific Management that deserves closer inspection.     

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.
