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.     

Von der „Natur der Sache”︁ zur Geschichte der Sprache Der Übergang von der Sprachforschung zur Sprachwissenschaft zu Beginn des 19. Jahrhunderts

From the “nature of things” to the history of language: The transition from the study of language to historico-comparative linguistics. This brief essay deals with a somewhat problematic phase in the history of linguistics and tries to investigate the process by which language could be understood as a historical phenomenon with a history of its own. This new understanding of language turned out to be the starting condition for a new and very prolific way in the study of language. The conjecture is that this is due to certain alterations in the semantic field of some important notions relating to language and its study. The process of alteration began by the end of the eighteenth century with conceptual achievements which could adequately be termed as temporalization of aspects of language and the notions related to these aspects. In connection with the so called discovery of the Sanskrit language and the gradual reception of its grammatical structure, looking upon language as an organic entity with autonomous and internal structures of developpement became possible after the German romantic language philosophy had developped a strictly abstract concept of language as a notion of form. This essentially metaphorical mode of speaking nevertheless inaugurated that languages were concieved of as having their own history totally independent of their speakers. With language as an autonomous object the study of language rapidly became the science of language.     

Dualistische Entwürfe zur Einheit der Naturphänomene und die Anfänge der Romantischen Naturphilosophie

The importance of German Naturphilosophie for the development of a unified view of nature is often emphasized. The search for ultimate unity of natural phenomena, however, was already too common among physicists of the waning 18th century to ascribe its popularity to the influence of philosophers. To avoid the plethora of imponderable fluids, many ?atomists”? reduced electric, magnetic, thermal, and chemical phenomena to a dualism of contrary principles, thereby prefiguring the ?dynamic”? ideas of romantic Naturphilosophen. In particular we show how Schelling's early account of his Naturphilosophie was shaped by J. A. Deluc's atomistic theory of gases and vapours.     

Alltagswissen – Körperwissen – Praxiswissen – Fachwissen. Zur Aneignung,Bewertungs‐ und Orientierungslogik von Wissenskulturen

Everyday knowledge – body knowledge – knowledge of experience – specialized knowledge: Acquisition, assessment and the orientation of logic concerning cultures of knowledge. – The essay explores changes in the understanding, legitimisation, and practice of midwifery. It was one of the earliest professional activities for women. During the eighteenth century a new culture of expertise emphasized theoretical knowledge and adherence to medical disciplines over the empirical practice gained by women. This early phase of professionalisation, with its hierarchies and preferred use of medically accredited knowledge, was not, however, solely divided along gender lines. Female professionalism was not just supplanted by male academic medicalisation. New ways of attaining and assessing knowledge, a different perception of how it is organised, and above all, social change created new patterns of understanding. This process achieved a new professional ethos. In pursuing the issue of gender, various examples are chosen to illustrate how changes in scientific knowledge and its relevant application are mediated. The construct of scientific knowledge and how it is used reflects gender relations and power structures. There is not only competition between female and male perceptions of knowledge, but also male stereotyping of female knowledge, in particular male notions of what kind of knowledge is necessary and how this is perceived by women. Karen Offen used the term ‘knowledge wars’ to describe how a monopoly of scientific expertise and relevant knowledge works within the professions.     

“… daß der Liebhaber etwas Erfreuliches und Nützliches zu leisten im Stande ist.” Goethe,Soemmerring und das Os intermaxillare beim Menschen

Goethe's theoretical comments on the acknowledgement of the natural sciences dilettante differ considerably from his own experiences in this role (Farbenlehre, Zwischenkieferknochen) of dilettante. Therefore, it seems necessary to raise general questions on the concept: dilettante of natural sciences during Goethe's time, furthermore, on the characterization and labeling of such a dilettante in an historical-scientific context. This is especially important since up to the present time this particular problem has hardly ever been examined. In addition, there is a summary of an historical case study, the discovery of the human intermaxillary bone by Goethe and of the specialists' reactions on this discovery, especially that of Soemmerring.     

Romantische Naturkunde - Die Doppelsinnigkeit der Naturbildung des Bernhard Heinrich Blasche (1766-1832)

Naturbildung, written by B. H. Blasche in 1815, seems a typical philanthropic study about science education private organized. But it also demonstrates romantic philosophy influences, which led at least from describing natural history to biology. There was no success in Blasche's reformatory efforts: first reason because the idea of private education-institution was out of discussion. Second reason was, on the way to stateorganized schoolsystem in Germany classic philology dominated and repressed deeply science education.     

Die Französische Revolution im Spiegelbild. Die Reaktion der deutschen Ärzte auf die Revolution und das Revolutionieren

The German physicans and medical scientists reacted to the French Revolution in several ways, if you judge only from the medical literature:

• 1 At the beginning of the French Revolution, the scientist answered with still silence, whereas the young intellectual generation was filled with enthusiasm. But after the battle of Valmy (1792) this enthusiasm vanished and they resigned to execute an equal revolution in Germany.
• 2 When, in the middle of the 1790s, scientists gave commentaries on revolutionary acts, they despised the revolution itself. This could only destroy the old – and even better – order. They argued that you can have recourse to science to avoid the political and socially deranged situation.
• 3 This rejection against the political revolution was combined with a rejection against the influences of natural philosophy on medicine. Schelling's philosophy plays the role as an scientific revolution with all negative aspects like the political one. In this sense, the science in the old scientific manner has to be an accepted refuge.
• 4 But in this retreat they developed ideas of German national science to conteract on the French influences. The consciousness of nationalism was supported by the scientists of romantic movements.
• 5 The following degree is characterized by a mental leap. Now, they argued, it will never be necessary to revolutionize the medicine: in science all the ideals of French Revolution are realized – freedom, equality and fraternity.
• 6 Consequently, only in a formal sense did they respond to the French Revolution and so they avoided recognizing, that science is influenced politically and also science itself exercises on in a political way.

     

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.     

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.     

Friedrich Ratzel and the nature of (political) geography

It is impossible to understand Ratzel's Politische Geographie without placing the figure of its author in the perspective of the critical bourgeois geography of the eighteenth century and the first half of the nineteenth century. From this point of view, Ratzel is the last representative of this bourgeois movement born in the first part of the eighteenth century in Germany with the name of “pure geography” or “natural geography”, and developed in the following century thanks to the great works of Karl Ritter and Alexander von Humboldt. The purpose of bourgeois critical geography was to create a geographical discourse (a reasoning) able to transcend the identification between geographic knowledge and cartographic representation that was maintained by the Staatsgeographen—that is by the state geographers who defended the feudal aristocratic regime. But it is precisely this identification that German bourgeois geographers appropriated in the second half of the nineteenth century, after the bourgeoisie came into power through a compromise with its ancient political opponent. Only Ratzel, direct heir of the Erdkunde tradition of Ritter and von Humboldt, was an exception by opposing the new bourgeois state geography with his own state-based geography.     

Das erste Jahrhundert deutschsprachiger meteorologischer Lehrbücher

Sequences of text books published during a longer time span offer the opportunity to describe the development and forming of scientific disciplines. Here, the forming of meteorology as a separate discipline is analysed from German textbooks published between 1803 and 1901. This first century of meteorological textbooks can be divided into three phases: (1) a phase of the final definition of meteorology as a discipline within physics (1800–1840), (2) a phase which sees meteorology as an established part of physics (1839–1870), and (3) a phase of further developments within meteorology on the basis of the theoretical equations of hydrodynamics (1875–1901) during which meteorology finally forms as a separate discipline. In phase 1, meteorological textbooks were written by physicists, mathematicians, and other natural scientists. In phase 2, the textbooks were based nearly completely on Pouillet's textbook on physics and meteorology, and finally in phase 3, meteorologoical textbooks were written by meteorologists. The Germanlanguage meteorological textbooks from 1803 to 1901 are listed in Table 1. These books document the shaking off of old views in the beginning of the 19^th century, the establishment of meteorology as a separate discipline in natural sciences in the middle of that century, and the beginning of a specialisation within meteorology at the end of that century.     

Universitäre Freiräume im Spätmittelalter als Wegbereiter neuzeitlicher Naturwissenschaft

University freedom in late Middle Ages as a way to modern natural history: The question regarding the relation between faith and natural history in late Middle Ages was answered in different ways. In the way of thinking shaped by Augustinian philosophy there existed, in early Middle Ages, a close connection between natural science and religious belief. In the second half of the 13th century attempts were made at dividing natural science from supernatural sphere. In late Middle Ages it was endeavoured not only to liberate natural history from the domination of theology and metaphysics but also to achieve the autonomous treatment of nature. These endeavours became fully accomplished by Nicolaus Copernicus.     

Scenic tourism on the northeastern borderland: Lake Memphremagog's steamboat excursions and resort hotels, 1850–1900

Lacking the salt-water beaches, accessible mineral springs, and rugged mountains that attracted the first tourists to the northeastern United States, the Vermont–Quebec borderland did boast a number of clear and picturesque bodies of water, the largest of which was Lake Memphremagog. Once this lake became accessible by rail, American and Canadian promotional literature and graphic illustrations emphasized the romantic nature of its paddle-wheel excursions, scenic landscape, and resort hotels. This type of tourism was depicted as essentially a passive, civilizing experience in which participants affirmed their aesthetic sensibility and social status by admiring the view of lake and mountains from boat decks and hotel verandahs. But the exclusive nature of this romantic sensibility was undermined to some extent by the fact that local newspapers and railway companies encouraged groups of people from the surrounding communities to join the sight seeing tours. Local entrepreneurs were also quick to take advantage of the market for scenery and, in contrast to other tourist zones, there was no apparent conflict with the industrial development that was taking place at both ends of the lake.     

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.     

Of love and national borders: the Croatian anthem ‘Our Beautiful Homeland’

Croatia became a UN member only in 1992, after the violent break‐up of Yugoslavia. Its anthem is marked by historically founded ambivalences as to the nature and territorial extent of the nation in question. This article offers an interpretation of the current version of the anthem and an analysis of the narrative and imagery of the nineteenth‐century poem from which the anthem originates. Three of the anthem's four stanzas speak about the Croats’ love for their homeland and their people and of the steadfastness and immortality of their love; the remaining stanza extolls the beauty of the homeland. By addressing the homeland's rivers and the sea directly, its singers appropriate this geography and so demarcate the borders of their much‐loved homeland. The anthem thus asserts Croatia's unity (against potential pretenders) and its unbreakable ties with its people. In contrast, the original fourteen‐stanza poem ‘The Croatian Homeland’, written in 1835, is a paean to the Croats’ ties to nature, their simple life and bravery – the romantic virtues of pure national souls. On their path to anthemhood, the four stanzas drawn from this poem have undergone significant modifications and additions, the result being a song that is doubly reassuring: it reassures the singers first of the people's love for themselves as a people, and second that this love is the means by which the ‘natural’ territory of the homeland is maintained.     

Zur Pluralisierung im Luthertum des 17. Jahrhunderts und ihrer Bedeutung für die Deutungen von ‚Natur’︁

Building on methodological considerations in cultural history and historical anthropology, the following contribution proceeds from the concept of ?nature’? rather than from ?natural science’?, with the former understood here as the object of culturally determined projections, values and practices. This ?constructive’?, practice‐oriented concept of nature exposes perceptions of and attitudes towards nature that, owing to the usual reduction of nature to natural science, would otherwise have remained hidden, but which may well be essential to its constitution. To a certain extent, the term ?nature’? continues the terminological extension from ?natural science’? to ?natural philosophy’?, but as a heuristic device it more strongly implies the significance of culturally mediated practices and dynamics. The essay raises the following questions: Which religious conceptions entered into which attitudes towards nature and which religious expectations and interpretive matrices were the motivating forces behind which studies of nature? The figures within seventeenth‐century Lutheranism who shaped and promoted nature‐oriented attitudes and practices were not the ?orthodox’? scholars more strongly tied to academic and controversialist theology, but rather reform‐oriented theologians critical of the church. In the context of the inner differentiation and pluralization of seventeenth‐century Lutheranism, these reform‐oriented groups not only inspired innovate theological projects but also assumed a leading role, along with liked‐minded Christian laypersons, in interpreting and studying ?nature’?.     

Die Verlegung der Berliner Sternwarte nach Babelsberg — ein konservativer Neubeginn

In 1913 the Berlin Observatory was moved from the center of the city to Babelsberg on the outskirts of Berlin, now part of Potsdam. The new observatory was considerably larger in size and with respect to its staff, and it had got a completely new equipment. At that time it was the most modern astronomical observatory in Germany and possibly even in Europe. However, the scientific results achieved afterward were not comparable to that of other institutions, especially in the USA. A main reason was the conservative concept for the observatory, drawn up by Wilhelm Foerster and his colleagues, and restricting the work to classical fields of astronomy. Foerster's successor Hermann Struve tried to follow rather strictly this concept as well as the traditions of his family of astronomers. This led to conflicts with his collaborators Eugen Goldstein, Erwin Finlay Freundlich and Paul Guthnick, who were interested rather in astrophysics than in the classical problems.     

Die Rezeption der humanistischen Gedächtnislehre bei Luther: Natur,Kunst und Konfessionen

Iconoclasm is one of the central characteristic of the reformation movement. In several books it was argued that there was a connection between iconoclasm and the interpretation of nature as a language and as a text since about 1600. This article discusses the artist as a creator in Renaissance culture. It shows the reaction of Luther to this concept and to iconoclasm, focussing on the connection between the Lutheran control of pictures and images and his conception of the mind and of memory on the one hand and of creatures as images and natural history on the other. In Lutheran context the book of nature was a book made of images as signs of the word of God.     

Zum Verhältnis von Religion und Zoologie im 17. Jahrhundert (William Harvey,Nathaniel Highmore,Jan Swammerdam)

Jan Swammerdam was one of the first scientists to do biological research on the basis of physico-theology. He was a very religious man and thought that by studying the secrets of nature he could best serve the Almighty God. He saw his life's work in demostrating the importance of God in the world of the smallest animals. The most important works of Swammerdam refer to the world of the insects and other lower animals, which he called the ?legions of the God of Israel”?, through which God tells mankind to recognize their sins, to desist from them and to honour him with greater humility. ?The miracles of nature”? he said ?are an open bible, which everywhere points to God as its eternal origin.”? This is one of the reasons for the title of the work Biblia naturae. It was Swammerdam's declared aim to demonstrate that the insects were no less perfect than the higher animals. Therefore, he tried to refute all three arguments used by his contemporaries to show up the difference between the higher animals and the insects: 1. insects were believed to have no inner anatomy; 2. they were thought to originate by spontanous generation; 3. development occurred through ?metamorphosis”?. Swammerdam succeeded in refuting all three arguments by exact studies of the nature and development of the insects. Most important for him was his aim to demonstrate that even the structure and the development of the smallest of animals demonstrate that they could only be made by God himself. Science as God's worship must be strictly objective, he said, because only than could one understand the laws of nature and in this way the real nature of God himself.     

„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.
