Proselytizing Islam — Problematizing “Salafism”

This article discusses the contemporary European setting pertaining to Islamic interpretations, mainly so called Salafi Islam. The empirical material is based on publications by a Swedish group that conducts street da?wa, aiming to proselytize among non‐Muslims. The ideology, as presented in official publications to be used for da?wa, is described and analyzed as part of a larger da?wa‐movement with Salafi‐inclinations in Europe. The group is not unique, but rather one example of many in Europe, at least concerning the activism advocated. The presentation of the group serves to reflect upon global influences and similarities among contemporary Islamic da?wa activism, as well as effects that the national context has on the choice of predominant themes addressed by the group as well as interpretative strategies used. The overarching aim with the article is to problematize the common usage of the concept Salafi among scholars of religion to describe and characterize contemporary Islamic groups of various kinds. The conclusion calls for a more nuanced approach concerning conceptualizations and the use of typologies in studying contemporary Islamic groups in a minority setting.     

“Marsh fever”—The geography of malaria in England

The marshlands of Kent and Essex had exceptionally high levels of mortality from the sixteenth to the nineteenth century. The unhealthiness of the environment aroused frequent comment during this period and it was attributed to an endemic disease known as “marsh fever” or “ague”. Marsh parishes were perceived both as a danger to the local inhabitants and as a deterrent to potential settlers. This paper traces the geography and history of the “marsh fever” in England and shows that the disease was, in fact, plasmodium malaria transmitted by anopheline mosquitoes. Malaria, once indigenous in the coastal marshes of England, had a striking impact on regional patterns of disease and death. The discussion concludes with an examination of the reasons for the clinical disappearance of malaria during the nineteenth century, its reappearance after the First and Second World Wars and the possibility of new outbreaks of malaria in the future.     

Das Problem der “entscheidenden Experimente”

In this historical essay an attempt is made to discuss the problem of decisive experiments both from the point of view of History of Science and of Philosophy of Science. The first part deals with Francis Bacon's idea of instantiae crucis and with the use of the term experimentum crucis mainly in optics. With respect to the experimental confirmation of Maxwell's electrodynamics the Duhem-Quine Thesis is discussed. Duhem had argued that not a single hypothesis but only a complete theory is examined by experiment. So a single experiment neither can prove nor can disprove a single hypothesis. With regard to Bucherer's and Neumann's data concerning the velocity-dependence of the electron's mass the question of the certainty of conclusions arising from experimental tests is treated. In the last parts the really historical problem of the decisive experiments is considered, namely the gap between the context of design of an experiment and the context of evaluation of an experiment in retrospect. The examples here are the Michelson-Morley experiment, the Franck-Hertz experiment, and the Compton-Effect. In the conclusion parity violation is discussed. Perhaps due to the possibility of a single alternative in theory and an unambiguous result of the experiment this test really was crucial. In general, however, the experimentum crucis will prove to be a very seldom event.     

Wissenschaft — Mathematik — Technik: Ihre Wechselwirkung in der Antike

The question whether there exists an interaction between ‘science’ (foreign text ignored) and ‘technology’ (foreign text ignored, esp. foreign text ignored) in Greek and Roman antiquity is discussed controversially until today. Especially representatives of the philologies strictly deny any form of relation, whereas modern scientists tend to take for granted that the current interaction between (exact) natural sciences and technology has always existed, at least since the beginning of real natural science founded by the ancient Greeks. This paper shows that both parties are right — at least in a certain way. Following current terminology and contents of ‘science’ and ‘technology’ there had been such an interaction — particularly with mathematics as linking element in so far as in antiquity especially foreign text ignored (mechanics) was regarded as applied mathematics and not as science. The strong interaction between pure mathematics and such fields of applied mathematics (namely mechanical technology) based on the fact that technological (mechanical) artefacts were properly constructed mathematically. Some of them are mentioned in this paper (astrolabes and sundials, waterclocks, tools and machines — especially lifting gears, bucket elevators, guns, pneumatic tools —, architecture of temples); in so far the supporters of an interaction between science and technology are right. However, the post-Aristotelian Greeks and Romans did not consider mathematics to be part of ‘science (of nature)’ as the post-kantian exact scientists do. Mathematics to them was a mere ‘art’ — consequently, in the mentioned cases there had been an interaction between ‘arts’ and of course not between ‘science’ and ‘art’ (technology); and in so far those are right who deny an interaction between natural science and technology. This shows that the contrariety of the answers to the question depends on the different terminology chosen. Following the current understanding of ‘exact natural science’ the answer is: yes; following the conception of ‘science’ in the self-understanding of Greek and Roman antiquity the answer is: no — and this is right as well! The reason for this apparent contrariety are just the different meanings and contents of ‘science (of nature)’ in antiquity and modern times.     

Von Vielschichtigkeiten und Verschränkungen “Kulturen der Wissenschaft – Wissenschaften in der Kultur”

On Multiple Levels and Linkages: Introduction to the Symposium ‘Cultures of Sciences – the Sciences in Culture’. – The article presents briefly approaches to cultural history and cultural studies that seem potentially useful to or have recntly been applied in historical studies of the sciences. The first section discusses three such approaches: discourse analysis, symbolic artefacts (images and text), and cultures of scientific practice. Each of the three approaches raises issues of its own, and all of them share a common problem characteristic of cultural and social history in general: linking micro and macro levels of analysis. The second section presents three approaches to resolving this dilemma by focusing on specific linkages between cultures of science (or culture in the sciences) and general history: scientific thought and practice as norms for professional behavior, for example in fields of knowledge dominated by women; spaces of knowledge, for example the city; and linkages of cultural, media and economic history in fields such as radio and television.     

Charcoal analysis and the “Principle of least effort”—A conceptual model

The applicability of the Principle of Least Effort (PLE) to interpretations of palaeoclimatic data is considered, and found lacking in some instances. A conceptual model is presented to determine situations in which the PLE may, or may not, apply. This helps identify when the PLE may be a useful model for interpretation of appropriate data sets.     

“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.     

Das erste zoologische Kompendium in der Zeit der Renaissance: Edward Wottons Schrift „Über die Differenzen der Tiere”︁

The English physian Edward Wotton wrote the first zoological compendium in the time of the Renaissance. As a convinced representative of Renaissance-Humanism Wotton strictly applied Aristotelian methodological principles to Aristotelian facts. In this way he tried to make Classical Antiquity complete; the Renaissance of ancient zoology is here tantamount to a new beginning. Wotton's achievement is in the first place to have provided a good summary of the whole of ancient zoological knowledge to which he added a few observations of his own. He carried through the Aristotelian concept of differentiation by many distinguishing features more strictly than Aristotle himself and all subsequent authors. In this way he attained the first zoological system, which influenced all later systematic attempts. The main Aristotelian groups are further subdivided and the Zoophyta are separated for the first time as an independent group. Wotton used a practical indexation method and got rid of an excess of detail in the text, adding critical annotations to each chapter. By means of the two indices, one of the names and the other of the parts of animal, Wotton tried to improve the precision of nomenclature and by this the identification of the objects under examination. His critical position on fabulous animals reveals his progressive mind.
