Die Komplementarität von interner und externer Wissenschaftsgeschichte

In studies of the history of science two apparently diverging ‘ideal types’ can be distinguished. The internal analysis relies on methodology and on the philosophy of science and concentrates on the cognitive system and on the sequence of theories. The external analysis relies on sociology, the history of institutions, biographies, etc. and concentrates on the social system and on the interrelationship between science and society. Neither of the two approaches can claim to cover the whole truth and to give the only possible (causal) explanation, The cognitive content of scientific theories and the social process of bringing about and using them are by their very nature complementary.     

Geschlecht und Gesellschaft: Die ersten Ärztinnen und sozialpolitische Vorurteile

The objective mode of scientific inquiry has increasingly been called into question especially within feminist theory. I have tried to introduce two methodological approaches in examing a small area of medical opinion-making in the medical press at a period in which the question of women doctors was being discussed, but very few women doctors were actually practicing in Germany. Methodologically feminist history sees gender as a structural component used to ascribe sexual division of labour and to form concepts of “masculinity” and “femininity” in a society. It does not define “women's history” as a separate sphere additive to other traditional areas of historical writing including history of science. The second methodological approach is that of deconstruction: “objective” statements in medicine and the biological sciences are part of social and cultural preconceptions. I have examined the pattern of unreflected scientific statements about women's claims to want to become doctors. The pattern is one of preventive prejudice: representative doctors wrote about women in physiological and biological terms of being “weak” and “unfit”. This was an effective strategy for maintaining a status quo of dequalification. The historical examination of women entering the professions has not so much to do with their own capacities, but rather with socially conceived forms of argumentation indirectly applied: preventive statements in medicine about biological function, the “weaker” sex, intellectual denigration, physiological determinism. Some of the statements I found are amusing, but the humour becomes bitter when the consequences enter our social consciousness.     

“Lachkabinett” und “großes Fest” der Physiker. Walter Grotrians “physikalischer Einakter” zu Max Plancks 80. Geburtstag

“Funhouse” and “Big Celebration” of the Physicists. Walter Grotrian's ?Physical One‐Act Play”? for Max Planck's 80th Birthday. On the occasion of Max Planck's 80th birthday on April 23, 1938, a “big celebration of the physicists” (großes Fest der Physiker) was celebrated at the Harnack‐House in Berlin. The festivities were organized by the German Physical Society. Part of the ceremony was a “Physical One‐act‐play” (Physikalischer Einakter) written by the Potsdam astrophysicist Walter Grotrian. The actors of the humorous play were chief protagonists in the development of quantum theory such as Debye, Sommerfeld and Heisenberg. In this essay we analyze Grotrian's drama against the background of both the festive event and the professional and social setting of the physicists. We argue that below the level of comedy a number of characteristic and normally unexpressed aspects of the epistemic culture of the German physics by the end of the nineteen‐thirties is treated in the play.     

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.     

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.     

Dom Hans van der Laan’s Architectonic Space: A Peculiar Blend of Architectural Modernity and Religious Tradition

This article discusses the design methodology of the Benedictine monk-architect Dom Hans van der Laan (1904–91), famous for his manifesto De Architectonische Ruimte (Architectonic Space, 1977), in which he proposed his ideal elementary architecture. In the past, this ideal achitecture was linked to Van der Laan’s proportional system and to his general approach as an architect rather than to his Catholic background. Consequently, the changing conceptual landscape in which he developed his ideas on the relation between religion and design was neglected. Yet, as this article will argue, it is only by carefully exploring the relation between Van der Laan’s attempts to define a fundamental architecture and his ambition to understand the religious traditions they may have sprung from that one can understand how his religion and design methodology influenced each other. Based on unedited primary sources (letters, notes, design sketches, lectures), this article reveals forgotten interconnections between Van der Laan’s religious and architectural thinking. By analysing these motifs, it offers new insights on the interrelationships between religion and architecture that go beyond the traditionalist-modernist dichotomy.     

Two Careers across Two Cultures

Beginning with my recollection of hearing C. P. Snow's ‘Two Cultures’ lecture, I sketch my experience of building two academic careers in succession, first in one of the natural sciences and later in the history of such sciences. I outline both the difficulties and the rewards that I encountered in crossing the alleged gulf between the sciences and the humanities, but also emphasise the diversity of cultures that I experienced within each. I describe my own encounter with the academic culture of continental Europe, within which the concept of a monolithic singular ‘Science’ could be dismissed as an ‘anglophone heresy’, and viewed from which the Two Cultures debate could seem both provincial and redundant.
