Analogien in Physik und Technik im 19. und 20. Jahrhundert

In this paper the use of analogies in physics and in technology is analysed. First the important role philosophically deep rooted analogies played in romantic physics is discussed. The work of Schelling and Ritter is treated in particular. Second the mechanical analogue models in the kinetic theory of gases and in electrodynamics are examined, as well as the severe philosophical criticism which they received. A sketch of the theory of the electron gas is presented as an example for the success and the shortcomings of analogue models. Finally mechanical and electric analogue models in technology are considered; moreover biological analogies in engineering research, and the principle of similitude as applied to model experiments in shipbuilding are discussed. The analysis of the historical examples shows that in the 19th and 20th century the word “analogy” is no longer a vague notion. It represents a scientific method, which, however, inevitably leads to both an extension of the original theoretical models and to special theories of mapping.     

Ars critica. Der Rhetorlehrer Quintilian als Vorbild für Begriffe und Aufgaben von Kritik in neulateinischen Reden und Schriften Deutschlands im 18.Jahrhundert

Theme of this article is the ancient Roman tradition of criticism based of the standard ">institutio oratoria« of the late Roman teacher of rhetoric Quintilianus and the reception of rhetorical and critical theory among German 18th century philologists. Just like Immanuel Kant's terminology of 'Kritik' the Latin terms critica and ars critica became in the 18th century basic terms for the research in the history of philology and the social importance of this scientific work. The researchers' documentations in the 18th century demonstrate the ancient tradition between criticism and the liberal arts of the trivium which are studies in rethoric, dialectic and grammar.     

Vertrauensvorschuß und wissenschaftliches Fehlhandeln — Eine reliabilistische Modellierung der Fälle Abderhalden,Goldschmidt, Moewus und Waldschmidt‐Leitz

Reliabilist philosophy of science considers scientific misconduct a transgression against the principles of good cognitive practice. Good practice in research is characterised by the reliability, efficiency and fertility of the cognitive processes involved. The reliabilist approach is closely connected to the idea of mutual cognitive dependency of the research community. Trust in the testimony of others is not an inevitable but a favouring factor of scientific progress — and misconduct damages the testimonial chain, respectively the principle of trustworthiness. Within the reliabilist framework, the main focus on questionable research is not on whether or not there are fraudulent intentions (that means particular mental events of the past), but on recognisable consequences for the research community. Criticising the constructivist modeling of questionable research, we reconstruct certain contributions by Emil Abderhalden, Richard Goldschmidt, Franz Moewus, and Ernst Waldschmitz‐Leitz as serious misconducts respectively frauds. We also show that specific social factors — often regarded as “apologising” conditions — decisively interfere with the principle of trustworthiness in the scientific community.     

Wissenschaft im Gehäuse: Vom Nutzen und Nachteil institutionengeschichtlicher Perspektiven

Research is realized in social and cultural context, it is established in institutions, as far as different forms and conditions of practice are concerned. In this article some German examples demonstrate how flexible and varied the institutions of research can be during the course of history of science. The first part deals with historically grown, yet chronologically overlapping institutions of research: beginning with the lonely scholar, going on to hierarchally organized big science and ending up with virtual institutions. In the second part, at the intersection of political‐social administration and styles of scientific thought terms like German Realpolitik, science in context, and science policy are discussed within the modernization process.     

Kleinstadt und Bibliothek in der Frühmoderne. Zu Genese und Struktur der Ratsbibliothek der fränkischen Reichsstadt Weißenburg

Small town and library in early modern times: Even small German imperial towns in particular were unable to conduct their daily business without maintaining a library with a wide range of excellent and usefull books suitable for employment by the judiciary, the administration, the health-care services, the church and school system as well as for supporting the interests of the town effectively. It is clear that the municipial council placed high value on the acquisition of the most important works in the field of law, theology and literature treated in school considering the relatively rational manner in which the “Ratsbibliothek” (library of the council) of the imperial town of Weißenburg (Bavaria) took stock of its books in the early modern times (16th to 18th century): this can be seen in the contemporary cataloguing (1600/1745/1829) of the library. Since the library orientated itself pragmatically towards the administrative interests of the town, there was hardly any inclination towards the acquisition of works in the fields of philosophy or poetry. — This study is based on the first edition of the “Beringer-catalogue” included (1600).     

Körpergefühl und Raumvorstellung: Leonardo und Descartes

“Experience and the conception of the world in science in transition to modern times” is the general subject. There are two different points to be made clear, i.e. 1. That the conception of the world had to be made imaginable by art before it could be taken over by science. The central perspective dates back to about three centuries before the time Descartes developed the co-ordinate system. 2. Furthermore it should be taken into account that it was first of all due to the lead of the painters (especially in the Italy of the Quattrocento’) that the possibility of making experiences had changed. In a space opened by a perspective view and seemingly thus appearing as measurable even the painted figures acquire a new reality. Due to his anatomic studies Leonardo could treat the natural movement of the figures shown in his paintings. It was the artists who first of all investigated optics and anatomy before relations could be measured with the aid of scientific methods ami before quantities — instead of qualities — could become the base of unbiased science, as called for by Galilei in 1623.     

Wissenschaftsgeschichte und Ur- und Frühgeschichte

During the past few years a history of special subjects and a history of science, being critical and historical as well as taking into account scientific theory and methodology, has established itself under the influence of philosophy in many domains of the sciences. Such a scientific history is now also required in the branch of the science of history. It demands the ability of re-evaluating historical sources and studies as well as the knowledge of the political aspect of a future scientific history. As a matter of fact a future scientific chronicle of prehistory has to examine not only the subject of historical research itself, but also its aim, method and the whole sociopolitical background. This is more important than a positivist study of individual and specific historical aspects, a thorough compilation of different approaches in historical research, scientists and institutions. It is also better than making an arbitrary selection of single biographies in order to have a political legitimation of the present state of research. Moreover, the danger of such a selection is the degradation of persons in history and the falsification of historical facts. Apart from a determination of the subject with regard to scientific and political aspects the search of historical clues as well as the re-evaluation of historical and archeological sources could both lead to a revision of prehistory.     

Das Arabische als Vermittler und Anreger europäischer Wissenschaftssprache

The role played by the ‘Arabs’, i. e. the peoples of Arabic-Islamic civilization, in the transmission and development of the sciences — from Antiquity and into medieval Europe — is well known. In the present contribution it is discussed in which way the ‘Arabs’ formed their own scientific terminology and in which way they contributed to the formation and development of the Western, European scientific terminology. In the translations of scientific works from Arabic into Latin in the middle ages, mainly four ways of rendering the Arabic terminology are observed: simple transliteration; modified Latinized transliteration; literal translation; and free rendering by newly formed or inherited Latin or Greek terms. In the course of time, transliterated Arabic terms were more and more suppressed — though many of them live on among us until today — and supplied by corresponding Western terminology.     

Aus Österreich emigrierte Sozialwissenschaftler. Überblick und Stand der Forschung

The article presents an general view over the enforced migration of Austrian social scientists after 1933. The author argues that the Austrian case is a specific one: first in consequence of the two successive dictatorships, second because of the devastating consequences of the emigration movement for the Austrian scientific community and culture. Only a few of the refugees returned to Austria after 1945. Further could be demonstrated that the Austrian refugees were quickly promoted in the scientific world of their exile countries, by way of comparison — especially in the United States.     

Wissenschaftliche Photographie als visuelle Kultur. Die Erforschung und Dokumentation von Spektren

This paper discusses facets of 19th‐century scientific photography as a visual culture. The example of spectral research and documentation is particularly well suited, because prismatically diffracted light from the sun or from luminous gases was one of the most frequently examined phenomena of that century. The results were significant not only for physics but also for analytical chemistry and astrophysics. The spectrum also served as an ideal test object for checking the effectiveness of a wide array of photochemically sensitizable surfaces to the various color regions. Scientific photography became the most important experimental technique in the infrared and ultraviolet. H. A. Rowland's spectrum charts are discussed as an example of the transition from comprehensiveness in documentation to fetishism. The discussion of the Lippmann process, one of the first methods of color photography, addresses the associated training of the eye. Issues of authenticity and the much averred ?mechanical objectivity”? are raised with regard to retouching. The overriding theme of visual science cultures leads furthermore to unanticipated interdependencies with other scientific fields, such as geography, and draws the importance of practitioners into the foreground.     

Isolde Hausser (7. 12. 1889-5. 10. 1951), Technische Physikerin und Wissenschaftlerin am Kaiser-Wilhelm-/Max-Planck-Institut für Medizinische Forschung,Heidelberg

Historical sociobiographic accounts on members of the scientific and technical professions in the years of the Weimar Republic and after, are as yet scarce. This applies notably to women in the scientific community. Having formally been admitted to academic studies at German Universities only in 1908, their claims of wanting to apply their newly gained knowledge and to pursue academic careers were still not unquestioned by society. The social and cognitive integration of “the female” in male dominated science organisation, especially in the natural sciences and their kin fields in industry, remains problematic to-day. Isolde Hausser, daughter of the ambitious but little succesful inventor-entrepreneur Hermann Ganswindt, took her doctoral degree in physics at Berlin University in 1914, then worked as head of a group at a “Telefunken” laboratory for vacuum tubes till 1929, before she became research scientist at the Kaiser Wilhelm Institute for Medical Research, Heidelberg. There she worked on photoerythemaes and the formation of pigment and discovered the specific action of longwave ultraviolet. She contributed important results to our knowledge on the constitution and the behaviour of organic compounds by modern physical methods. She died of cancer on 5th October, 1951.     

„Und setzet eure Worte nicht auf Schrauben”︁ Medizinische Semiotik vom Ende des 18. bis zum Beginn des 20. Jahrhunderts - Gegenstand und Forschung

There is no doubt that medical semiotics are having a revival at the moment. Different aspects of yesterday's and today's interest in semiotics and in the historical interpretation of signs of disease in the context of theory and history of medicine can be illuminated: their deciphering as the history of the sign in medicine by historic science, their overestimation by philosophy during the Age of Enlightenment, their reduction to a phenomenology of medicine and natural science during the first half of the 19th century and their transformation to medical diagnostics since the middle of the 19th century and recently even their functionalization as methodical instrument within the history of science. The following will show the change in meaning of medical semiotics. Modern development and especially the transition to medicine, based on natural science, will be emphasized.     

Britische Politiker als Liebhaber der Wissenschaft (ca. 1850–1914) — Zur Ideologie des Amateurismus

The various scholarly and scientific endeavours — comprising both arts and sciences —, which British statesmen persued in their leisure time, transcend the mere biographical aspect. In the light of the slow, yet steady professionalisation of educational and political institutions, many of them modernised or newly created in order to achieve what came to be called “National Efficiency”, the literary and scientific pastimes of men, like Gladstone, Morley, Salisbury, Balfour or Haldane, seemed soon to become somewhat obsolete. Yet, it is argued, that the often professedly amateurish activities did not merely display the traditional hobby attitude to the sciences, so characteristic of the wealthy aristocrat, but in some cases revealed a good understanding of the scientific and educational needs of society, leading up to their active advancement. The British amateurs, it would seem, were pleading for providing a balanced higher education and training, rather than going for the technical excellence of the political rival Imperial Germany, which dazzled and, at the same time, intimidated some of them.     

Jesuiten zwischen Religion und Wissenschaft

Natural sciences and natural philosophy of the Jesuits are based on theology. At least the concept of God is an integral part of their theoretical structure. Examples are taken from Rudjer Boskovic, Honoré Fabri and Nicolaus Cabeus. In fact, the Jesuits, e.g. Theophil Raynaud, dealt with natural theology as the spiritual foundation of knowledge independent of revelation. But natural theology, as in Raimundus Sabundus, has an anthropocentric and hence moral dimension: it links knowledge with religion. ‘Ignatius of Loyola influenced decisively the Jesuits’ concept of science and its relationship to religion through his Spiritual Exercises in which meditation and religious practice are developed into a technique and a scientific approach to faith.     

Naturwissenschaft und Religion in den Niederlanden um 1600

Dutch science flourished in the late sixteenth and in the seventeenth century thanks to the immigration of cartographers, botanists, mathematicians, astronomers and the like from the Southern Netherlands after the Spanish army had captured the city of Antwerp in 1585, and thanks to the religious and the socio-economic situation of the country. A strong impulse for practical scientific activities started from the Reformation, mainly thanks to its anti-traditional attitude, which had an anti-rationalistic tendency. Therefore, in the Northern Netherlands there was no ‘warfare’ between science and religion and the biblical arguments leading to Galileo's condemnation were not used. Although the growth of the exact sciences and of technology in the late sixteenth and the seventeenth centuries in Protestant cirles may be partly attributed to the expansion of trade, industry, navigation and so on, this does not explain why there was also at the same time a great interest in subjects as botany and zoology, which had no immediate economic utility. There were discussions about Copernicanism and Cartesianism. So a number of astronomers and theologians rejected the earth's movement on scientific and religious grounds, but there were also those who did not reject the Copernican system on biblical grounds. In the seventeenth century there was much discussion between science and religion in the Northern Netherlands, but that discussion was not followed by censure by the Church of the State. In the Republic there was a large amount of intellectual freedom in the study of the natural sciences, thanks to practical and ideological considerations. In the eighteenth century the seventheenth century tension between science and religion changed into a physicotheological natural science. It was believed that investigations into the workings of nature should lead to a better understanding of its Creator. So Bernard Nieuwentijt in his well-known book: The right use of-world views for the conviction of atheists and unbelievers (1715) intended to prove the existence of God on the basis of teleological arguments.     

Zur Geschichte des Kaiser-Wilhelm-Instituts für physikalische Chemie und Elektrochemie. Zur geplanten Veränderung des Instituts in eine Forschungs- und Entwicklungsstätte des Heeres für den Gaskampf und Gasschutz auch in Friedenszeiten 1916 und nach 1933

A Contribution to the History of the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry: On Projected Changes of the Institute into a Research and Development Center of the Army for Chemical Warfare also in Times of Peace 1916 and after 1933. — The Kaiser Wilhelm Institute for Physics and Electrochemistry, today named after its first director Fritz-Haber-Institut, was in the first World War a place of research on chemical warfare. Evidences in the Archive for the History of the Max-Planck-Gesellschaft show that it was planned during the war to continue research in this area in peacetime. To realize this Fritz Haber proposed to found a special Kaiser Wilhelm Institute. As this could not be accomplished the war ministry founded 6 million marks to establish an extra department in the KWI of Physical Chemistry and Electrochemistry just before the end of the war. After Germany lost the war these were used for other research areas while work on chemical warfare was carried out elsewhere. When Fritz Haber resigned 1933 because of the race-laws of the nationalsocialists the war ministry in cooperation with the ministery for culture nominated an obliging scientist as director of the institute with the aim to take up again research in the area of chemical warfare despite of the opposition of the president of the Kaiser-Wilhelm-Gesellschaft and the ministery of the interior. After that time until the end of the second world war 1945 a good part of the work carried out in the institute was done for the war ministry.     

Gesundheitspolitik im 19. und frühen 20. Jahrhundert — Deutschland und England als Beispiele —Bericht über eine internationale Arbeitstagung am Zentrum für Interdisziplinäre Forschung der Universität Bielefeld, 7.–9. November 1986

Recent German publications on the social history of health policy stress longterm developments. Especially the preconditions, concepts, and anticipated as well as unexpected consequences must be elaborated more clearly. International comparison seems to be a valid scientific tool for this purpose. An international working group met at the Center for Interdisciplinary Studies/University of Bielefeld for a symposium on “Health Policy in the 19th and early 20th Century — Germany and England as examples”. The general subject was divided in several areas of discussion: social reactions to the cholera; hygienization of every-day-life; imperialism, armed forces and health policy; developments in occupational medicine.     

Zoologische Gärten in Stadtkultur und Wissenschaft im 19. Jahrhundert

The foundation and administration of European Zoological gardens in the 19^th century is analized. It is significant of such new institutions, that they are founded in the large cities, and that most of the founders looked at the great models in Paris and London, which are described first. Further it is shown that the change from princely menageries to public Zoological Gardens is caused both by common interests in people's education and pleasure and by scientific aims which leaded to choose the name Zoological “garden” in analogy to botanical gardens. It seems to be characteristic of such public institutions created by citizens in the 19^th century that they are mostly supported by commercial or scientific local societies. This is exemplified by describing the administration of the Zoological gardens of Berlin (1841), Frankfurt (1856) and Hamburg (1863), which initiated also research for acclimatization of wild animals.     

Die Embryologie im Spannungsfeld zwischen Tradition und Empirie

Already in classical antiquity people dealt with the principle of formation, developing different theories. Researchers in the renaissance, working in the conflict zone between tradition and experience, tried to prove one or the other of these theories by the means of new observations, especially of chicken development. Aldrovandi was the first to see the real principle of formation of the hen's egg, i. e. the blastodisc, but he didn't recognize the importance of his discovery due to his close adherence to Aristotle in the theoretical field. Fabricius even thought that traditional knowledge was of more importance than his own excellent observations. Parisano was the first to succeed in making a correct interpretation of the function of the blastodisc, but only by holding to a ‘false’ classical theory. Harvey combined his attempt to restore the developmental theory of Aristotle with a religious interpretation postulating God's intervention in all development. Subsequent to atomism, Highmore evolved a two seed theory of development, which in his view made a permanent engagement of God superfluous. Also the first observations using the microscope did not contribute to any improvement in developmental theory. Malpighi used them to confirm the theory of epigenesis, whereas Croone attributed to a piece of blastoderm the proportion of a whole embryo to demonstrate his ovistic theory of preformation. The founder of animalculism Leeuwenhoek, an amateur researcher, was at first not influenced by the trends of the scientific community. He postulated that the spermatozoa, which he discovered, contained perfect miniature animals. His investigations are a good example of where prejudices can lead, even when the observations are excellent. In the 17th century the tension between experience and tradition shifted in favour of experience, but a final solution had not by any means been reached.
