»…über Sekunden lacht man nicht« — Über die Folgen der Anwendung von Genauigkeit und Präzision in den Wissenschaften. Einführung in das Tagungsthema

Since the time of Descartes science has been influenced by the demand for precision and accuracy in research. In the 20^th century also humanities began to submit to this demand. The term precision itself has a far‐reaching and historically grown semantics. As a consequence of the attempt to answer precisely and irrefutably to scientific questions, achieved knowledge today is only valid for an increasingly narrow range.     

Prestige und gemeiner Nutzen Universitätsgründungen im deutschen Spätmittelalter

The medieval German university entered the picture late but thereby as a new and third type of university in Europe besides Paris and Bologna: This was the ruler-controlled ‘Four-Faculties-University’, which powerfully integrated the socially very different associations of liberal arts, theology, medicine, and law. From the beginning on the ‘German type’ was tied to the princely founder, his court, his dynasty, and his territory (in some cases also to the municipal leadership), and it was politically subjected to his will. All foundations produced prestige and dynastic need at first rather than public need (utilitas publica), respectively the advancing of common learned education and science. The great royal dynasties of Luxembourg, Habsburg, and Wittelsbach began founding in Prague, Vienna, and Heidelberg. Up to 1506 all the seven prince electors, some more important princes and big towns of the Holy Roman Empire had their university or had relations to a university. Public need was rather an indirect result: university students utilized surprisingly strongly the possibilities offered by the subsequent university foundations in Germany - about 200.000 people during a long-term 15^th century. However, it has to be thought over in the history of science and effectivity of the German universities in a European frame, that more than 80% of them were ‘only’ students of arts.     

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.     

Zwischen Arbeitslosigkeit und Berufsverbot: Die deutschsprachige Ärzte-Emigration nach Palästina 1933–1945

When the National-Socialists started their restrictive measures against Jewish civil servants and professionals in 1933, they caused a wave of emigration only to be surpassed by the one following the Anschluß of Austria and the ‘November pogrom’ in 1938. Due to their great number, jewish doctors were to become the main object of Nazi persecution in the professional group. Up until 1935 Palestine was their main destination of immigration. In 1935 the British Mandatory Government passed a numerus clausus which mainly cut down the licensing of newly arrived doctors. The article deals with the social problems caused by the mass immigration of a highly qualified professional group in Palestine and with the fight against the restrictive measures of the mandatory Government. A short retrospective glance is cast at the situation in Palestine before 1933. Finally an outlook is given at the impact of this immigration on the health system in Israel.     

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.     

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.     

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.     

Verzeitlichungs- und Historisierungstendenzen in der frühen Geologie und Paläontologie

Steno described in 1669 geological sections which were interpreted as the result of a series of earlier events. Steno used actuogeological methods. This was the first step towards temporalizing nature. Steno was succeeded by a lot of other researchers from different European countries. It is amazing to see, that “actualism” was widespread during the 18th century. The next step was the discovery that fossils are extinct beings (Ray, Hooke and others). Using methods of comparing anatomy W. Hunter (forerunner of Cuvier) could prove in 1769 that the Mastodon is an extinct vertebrate. The work of Soulavie in France (1780) is stressed. He held in his hand the key for solving the problem of index-fossils. About 1800 the importance of fossils for stratigraphy and describing a history of the earth was recognized. Theories and hypotheses were needed to explain the fossil documents (strange shells in older strata and higher developed mammals in younger strata). All these theories couldn't propose a feasible mechanism for the change of beings during the history of the earth. But it could be said, that all fossils proove a history of life and the earth i. e. a progressive development in one sense, a development which is not reversible.     

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.     

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.     

„Und nur die Zukunft wird Klarheit bringen!”︁Der Fall des Biomediziners Jacques Benveniste aus dem Jahr 1988 im Blickfeld der wissenschaftlichen Publikationsorgane und der Laienpresse

Scientific disputes on the objectivity of research results are an integral part of the collective production of knowledge. One motivation to study cases of scientific controversy is the attempt to discover general patterns in the behaviour of participants and institutions involved in such controversies. Yet, for there to be a controversy, one must assume an important amount of social interaction, so much so that it renders it an essentially social phenomenon, which is accessible to historical study. Cases of obvious scientific fraud, in addition, are neither clear‐cut nor rare and the mere accusation of scientists by their peers frequently constitutes considerable examples of scientific debate. Together with this, it is often assumed that publication organs play a dominant role in directing the lines of scientific controversy, but their institutional significance and the task of individual editors remain widely unexplored. The present article studies the prominent Nature affair of the Parisian biomedical scientist Jacques Benveniste, both, from a perspective on scientific fraud and on the beginning and closure of scientific disputes. One of the most remarkable features of Benveniste's antibody dilution experiments was that they stroke at the foundations of modern physical and biomedical sciences. Could recent history of science actually resolve the case of the so‐called ‘memory of water’ phenomenon?     

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.
