Eine naturwissenschaftliche Forschungsbibliothek des 18. Jahrhunderts: Die Bibliothek der ‚Naturforschenden Gesellschaft’︁ zu Jena

The ?Naturforschende Gesellschaft’?, founded in 1793, proved instrumental for the development of science at the University of Jena around 1800. Its library can be considered as one of its most important facilities provided for research and for the education of students. Since this library has been preserved almost without losses, we can ask whether this library served the purpose of a research library in the newly established field of ?science’?. In consequence, the role of scientific societies and the genesis of specialised libraries in the area of science can be investigated in an exemplary case, with implications for the concept of scientific research around 1800.     

Messen und Zählen. Die Herstellung des normalen Menschen als Maß der Gesundheit

The emergence of a ‘norm of normalcy’ in 19th century laboratories and hospitals was in no way simply a byproduct of the scientific search for knowledge. It was instead closely associated with expectations of social egalitarianism which merged with the moral economy of a new scientific objectivity. The establishment of normal people as a valid measure for a population socially divided and segregated in estates was thus an essential element of the processes of social formation which created our modern society.     

Die Entwicklung der Sozialgeschichte der modernen Mathematik und Naturwissenschaft und die Frage nach dem sozialen Raum zwischen Disziplin und Wissenschaftler

The use of the concept of social history of science is sketched in the Anglo‐American and the German discussions from the mid 1970s up to recent work. By presenting a ‘social map’ of a selected scientific community it is argued that between the categories of discipline and single scientist there exists a wide ‘social space’ of groups within which science is pursued. In adopting a milieu theoretic approach an ecology of science is proposed as a suitable extension of the social history of science.     

Romantischer Dilettantismus — Johann Wilhelm Ritter und die Begründung der Elektrochemie

In this paper the psychological and historical problems of the german philosophy of nature at the time about 1800 are described. During this time the romantic philosopher and scientist of nature Ritter developed a new scientific branch of knowledge: the electrochemistry. Ritter represents exemplarily the type of a romantic dilettante. In this period, the problem of dilettantism got a new validity, especially by Goethe and Schiller: it was recognized as a positive power of human. In the romantic dilettantism of Ritter three aspects are shown: 1st, romantic dilettantes are intellectual flaneurs; 2nd, romantic dilettantes confront facts and general provisions, which up to this moment are supposed to be paradox, and obtain by this method a synthesis; 3rd, romantic dilettantes favour the intuitive power.     

Reformation(en) und Wissenschaft(en). Einführung in das Tagungsthema

Based on a brief historiographical survey, the article aims at tracing some intellectual relationships between early modern science and the protestant Reformation (or the various individual reformations underlying it). Besides the mere structural analogies of the two reform movements and their common debt to Renaissance humanism, common elements such as the new reading of texts and the new role of the individual, but also the philosophical link between voluntarism and the notion of natural law, are discussed. However, the ambiguous attitude towards natural knowledge and the wide variety within the European protestant movement ask for a much closer look into the relationships between science and the Reformation than has been hitherto been achieved.     

Die Apotheke als Forschungsstätte

From the beginning, next to their essential function of preparing drugs pharmacies also served as educational institutions, in particular for the instruction of their own rising generation. Especially between 1750 and 1850 pharmacies in addition were engaged in scientific research. It were basically experimental‐analytic chemistry and after 1800 mainly phytochemistry which inspired numerous apothecaries to do corresponding work in their laboratories. For many of those scientifically ambitious pharmacists, however, pharmacies were merely a starting point in their professional career. More or less rapidly, they turned to other places of activity which were organizationally, socially, and intellectually of higher standards (e.g. academies or universities). There, they were better able to realize their research interests frequently roused and shaped in the pharmacies. When around 1850 chemistry as an autonomous discipline definitely was established at the universities and competition became increasingly apparent through the rising chemical industry, the former meaning and function of pharmacies as places of scientific research disappeared more and more and was completely lost about 1900.     

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.     

Disziplinerneuerung und Universitätsreform: Das Ius publicum Romano Germanicum

What caused the reforms which permitted the universities in the Holy Roman Empire to become leading places of scientific communication and mental orientation for centuries? In most cases, outside influences - pressures from governments, princes, scholars, councillors, consistories, or, as we would say today, state and churches - were decisive. But some reforms were the consequences of paradigm-changes within the universities themselves. Such shifts were less likely to originate with faculties concerned with medicine or the natural sciences than with those which were concerned directly with the political community or human societies. This changed only in the nineteenth century, which cannot be dealt with here.     

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.     

Der Kampf gegen den „Schwarzen Tod”︁. Quarantäne und Epidemiebekämpfung der frühen Neuzeit im Mittelmeer aufgezeigt am Beispiel Maltas

During early modern period Mediterranean people feared epidemics far more than war and other destructive activities. Where epidemics, especially the plague, struck, all communications broke down and trade just withered away. With the coming of the Knights of St. John in 1530 the Maltese Islands became increasingly important as an international boarding place in the very center of the Mediterranean. Soon the maritime development of the Order's State was enhanced by the high regard in which the Maltese Quarantine System was held by European countries in the 17th and 18th century. The aetiology of plague was then unknown and the restrictive measures adopted by the Maltese Quarantine System too were in accordance with the approved epidemiological practices and theories of the time. This article tries to single out the importance of the Maltese Quarantine as a kind of medical “shield” for the southern European countries.     

Über die Aufhänge- und Anzeigevorrichtung der ägyptischen Waage der Pharaonenzeit

A number of different and partly contradictory interpretations about the suspension and the indicator system of the ancient Egyptian balance has been given so far. In this article previous explanations of these devices are presented and critically considered; at the same time the balance of the Egyptians is included in the complete evolution of this instrument. Based on original Egyptian colour drawings on papyrus taken from the Book of the Death and considering weighing techniques, it is stated that all interpretations given so far are not capable of providing a satisfactory explanation of the function of these devices. The interpretation given already in 1888 by Sir Flinders Petrie comes closest to the real function of the indicator system: According to his assumption the device consisted of a solid pointer attached to the beam, in relation to which a plumbline was observed after the oscillations had stopped. This interpretation, however, has to be varied or to be complemented by taking into consideration the special drawing technique of the ancient Egyptians: Processes were drawn in a reproduction technique which consisted in the simultaneous combination of a top view and a side view. A new hypotheses about the function of the suspension and the indicator system of the ancient Egyptian balance is presented, which has the advantage of agreeing completely with the Egyptian drawing technique and which, in addition, ensures optimum precision of the weighing procedure.     

Die Gesellschaft Naturforschender Freunde zu Berlin ‐ Bestand und Wandel einer gelehrten Gesellschaft Ein Überblick

The article deals with the foundation and development of the society Gesellschaft Naturforschender Freunde zu Berlin in the 18th and 19th centuries, its position as a privat society for natural history in Berlin, and its relation to Freemasonry. The paper shows the change of meaning of these society, especially after the foundation of the Berlin university in 1810.     

Fotografie als Wissenschaft

Photography as Science: In 1908 the English physicist Arthur Mason Worthington published A Study of Splashes, a treatise on the physical behaviour of falling drops. The photographic experiments were performed by means of an electric spark „in absolute darkness”︁. Worthington's experimental practice dealt with two different areas of knowledge production: an area the operator could perceive control from the outside and a corresponding black-box where the photographic recording itself took place. The paper discusses the epistemic challenges of this specific shift from imperceptible events to their photographic representations. It shows to what extent the information revealed by the photographic apparatus had to be converted, for it did not speak for itself. Thus, Worthington's work went beyond the classical dichotomy between objectivity and imagination.     

The prescription as literature

In the medical writings of antiquity the recipe, a basic form of scientific writing, was considered a literary genre with conventions of its own. In texttype-linguistics, however, the recipe plays only a minor role; in studies on the history of literary short texts it is hardly ever mentioned and, furthermore, it has come to the conclusion that the recipe's function has lain solely in the curing of the sick. The present study focuses on its multifunctional character. A collection of widely scattered and hardly accessible recipes shows that the recipe adopted functions beyond giving technical directives. Its multifunctionality in the German literature of early modern times is manifest in medical and cooking jocular recipes, cooking recipes in minnesang, mock recipes aimed at physicians and astrologers, recipes of spiritual-religious content, recipes containing art and literary criticism as well as recipes in a moral-satirical or a political-agitative vein.     

Pest,Stadt, Wissenschaft — Wechselwirkungen in oberitalienischen Städten vom 14. bis 17. Jahrhundert

After the Black Death of 1348 the Plague was not only the cause of personal disasters and individual despair, but was also of political and social significance. Each outbreak of the epidemic implied a crisis for the community with crucial consequences for trade, jurisdiction, administration, executive powers and for food supply. The faith in authority by the leading university medics was tragic, as they subscribed to the hippocratic-galenical humoral pathology and to the miasmatic theory. On the other hand, municipal authorities, from the 14th century onwards responded to the epidemic in a pragmatic manner, isolating the sick, carrying out checks, imposing trade embargos and special epidemic laws. From the 15th century onwards people were also put under quarantine. The medics' role, their relationship with the government and their tendency to play down the diagnosis will be discussed at length, together with the questionable tradition of the Regimina pestis.
