Geschichte der Raumakustik im evangelischen Kirchenbau des 19. Jahrhunderts

The history of the science of room acoustics in the 19 century is studied with the example of the buildings of churches. Many architects of this century tried to make use of the acoustical laws in their plans, but only a few physicists did research work in this field.     

Die Mathematisierung der Naturwissenschaften vor dem Hinter-grund der Bildungsvorstellungen des 19. Jahrhunderts

Both, astronomy in the first half of the 19th century and physics in the second half of the 19th century functioned as models and paradigms for the other sciences. The paradigmatic character of a theoretical, mathematical astronomy was due mainly to its capability to predict future events. According to the influence of the Romantische Naturphilosophie the mathematization of physics in Germany took place belatedly compared to France. A modified Newtonian research program with its mathematical implications was adopted by German physicists only after the establishment of the principle of energy conservation. German physicists of the late 19th century claimed over and above the results of physicists the successes of German technology for physics and interpreted these achievements as “cultural” achievements. They combined this claim with a request for a better representation of physics in the curricula of secondary schools so as to be comparable to that of mathematics. The resistance of the most prestigious secondary schools, the Humanistische Gymnasien, against this request meant that the concept of Bildung as propagated by physicists was not accepted generally in Germany.     

Die Fotografie – ein neues Bildmedium im Wissenschaftspanorama des 19. Jahrhunderts. Einführung in das Symposium

Photography – a novel medium of scientific representation in the XIXth century array of arts and sciences. To delve into various nineteenth century academic disciplines under the heading ‘photography in the arts and sciences’ as did last year's annual conference of the History of Science Society – the interest in such a topic only partly stems from the ‘iconic turn’ that has generally enlarged the scope of the social sciences in recent years. A more poignant feature in any such present day study will probably be a basic scepticism facing the fact that in public use photographs have been manipulated in many respects. Yet, while shying away from any simple success story, a historically minded approach to changing ‘visual paradigms’ (Historische Bildwissenschaft) has begun to emerge. In this context, it has proved of considerable heuristic value to reconsider the role of early photography in an array of science, arts and technology: Since the reliance on the traditional ways of sketching reality persisted, in many an instance where photography was introduced, the thoughts the pioneer photographers had about their new, seemingly automated business, call for close attention. Thus scholarship sets up a parallel ‘discussion room’; the lively debate on the benefit of academic drawings as opposed to photographic portraits is a case in point. Some fairly specialised reports on photographically based analyses, such as electron microscopy, point to a borderline where the very idea of representation as a correspondence of reality and imagination gets blurred. Even though any ‘visual culture’ will have to shoulder the ‘burden of representation’, it is equally likely that it will offer a deeper sensibility for the intricacies entailed in the variegated ways of illustrating or mapping chosen subjects of scientific interest. Scholarship may thus somewhat control the disillusionment that by now has become the epitome of writing on photographic history. Provided with a renewed methodological awareness for the perception process and its photographic transition, historians may strike a better balance between the ever present tendencies of a realistic and an aesthetic way of picturing the world we live in.     

Die Idee einer historischen Entwicklung der Krankheiten des Menschengeschlechts und ihre Bedeutung für die empirische Medizin des frühen 19. Jahrhunderts

In early 19th-century German medicine many doctors had a strong interest in historical pathology. They investigated the historical records of fevers and epidemics in detail, trying to find out how the changing influence of the epidemic constitution worked and hoping that history would help them to define specific disease entities. The underlying theory of this endeavour was that diseases undergo a historical development similar to the evolution of plants and animals. This paper tries to show that historical pathology was, in its time, a legitimate attempt to solve the most urgent problems of empirical medicine.     

„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.     

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.     

Deutsch-italienische Wissenschaftsbeziehungen im 18. und 19. Jahrhundert — Dimensionen und Perspektiven

The scientific interrelationships between Italy and Germany in the 18th and 19th centuries — a hitherto neglected area of research — are discussed in an overview according to the following ten dimensions: language knowledge and translations; reviews and bibliographies; library content; personal contents and correspondance; travel reports and travel guides; diaries and autobiographies; university studies and research sojourns; membership in academies and scientific societies; practical and theoretical resonance; comparisons to other countries. This approach, which has to be concretized in future studies, promises at the same time general insights into the logic of science and its progress.     

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.     

„Siege der Freiheit,welche die Menschen durch die Erforschung des Grundes der Dinge errangen”︁ Wandlungen im politischen Selbstverständnis deutscher Naturwissenschaftler des 19. Jahrhunderts

“Victories of Freedom which Humans Achieved by Research in the Foundation of Things”. - This article analyzes the political self-conception of leading representatives of the natural sciences in 19th century Germany. It is argued that the main feature of this self-conception which remained constant over the time consisted in a strong “rationalization-imperative”, i.e. the postulate that state and society have to be reshaped on the basis of natural science. On the other hand, this imperative was put forward in very different forms and with different political content: it shifted from revolutionary aspirations in the period of 1848 to moderate and sometimes even reactionary positions in the last decades of the century.     

Spezialisierung und Bildungsanspruch. Zur Geschichte der Technischen Hochschulen im 19. und 20. Jahrhundert

In the late 19th century at the “Technische Hochschulen” the understanding of “Wissenschaft” and “Bildung” changed considerably. During the 19th century the “Polytechnische Schulen” and “Technische Hochschulen” adopted the neo-humanistic standards of “Bildung”, established by the universities and the “Humanistische Gymnasium”. At the end of the century they joined the “realistische Schulbewegung” which emphasized the value of mathematics and natural sciences, taking issue with the classical languages. At the same time, systematic experimentation was added to mathematics, natural sciences and technical experience to constitute the specific methodology of engineering sciences. Attempts to define specific technical elements of “Allgemein-bildung” did not succeed as a result of the rapidly increasing differentiation and specialization of engineering sciences.     

Arbeit und Zeit,Körper und Uhr: Die Konstruktion von ‚effektiver’︁ Arbeit im ‚Scientific Management’︁ des frühen 20. Jahrhunderts

The concept ‚Scientific Management’︁ was invented in 1910 for what was then called the ‚Taylor‐system’︁ of shop management. Frederick W. Taylor had developed his system to eliminate the “waste of human effort” mainly by “time study”, the analysis of the work of “first‐class workman” with a stop‐watch and the synthesis of standard times for given tasks which make the “waste” of effort visible and measurable. A reading of Karl Marx's work shows the “paradigm of productivity” governing mid‐century discussion of the value of labor. Time is a central element in the valuation of industrial labour, but only with Taylor the precision of the stop‐watch is introduced to observe and control the productivity of the body of the worker. As disciples of Taylor Frank and Lillian Gilbreth introduced motion studies and micromotion studies into Scientific Management. Their analysis of the motion of workers, technically assisted by high‐speed watches and cameras, goes beyond the surface‐observation of the first‐class workman to enable the design of efficient motion. The body of the worker is represented in lines of light and tables of data. The objects of desire are the time‐lines of efficiency and productivity. In both cases, Taylor and the Gilbreths, various observations further lead to the conclusion that science and schooling are an important historical background to the rise of Scientific Management that deserves closer inspection.     

Wissenschaftswachstum in wichtigen naturwissenschaftlichen Disziplinen vom 17. bis zum 21. Jahrhundert

The Growth of Science within Important Scientific Disciplines from 17th to 21st century. – In this paper the growth of knowledge is investigated for the disciplines of Astrophysics / Astronomy, of Physics and of Chemistry in the last centuries. In this context the main emphasis is devoted to the discussion of the growth of literature. Besides, this is also illustrated by the growth of indicators like for example important books, new discoveries in science, the chemical elements, the known chemical compounds and the number of known inorganic chemical structures. Compared to numerous earlier studies a systematic evaluation of all presently available data sources is carried out. The data are fitted by different mathematical growth models (linear, quadratic, exponential, hyperbolic). These are discussed and compared. As far as the exponential growth model is applied the doubling periods obtained have values between 11 and 32 years for the cumulative total of publications, between 24 and 98 years for that of important books, between 79 and 163 years for that of new discoveries and between 10 and 14 years for that of chemical substances. From an order of magnitude point of view this is in agreement with the results of other authors. It is however also demonstrated that the exponential growth model which is normally used is not necessarily the best to describe the growth of the data. Other models are often better suitable to explain the growth. It is shown that linear growth of the yearly publications describes the data better than exponential growth in certain epochs. In this latter case it is demonstrated that the parameter (linear slope) for the rate of increase has a constant values in certain epochs, but rises in steps from epoch to epoch by a factor of 3 to 40. After the second world war the linear growth model for the yearly publications or the quadratic growth model for the cumulative total of publications respectively delivers the best results. This is therefore used for forecasting the future.     

Lebensaltertheorien in der Anthropologie der Romantik

Theories of stages of life within the anthropology of romanticism. – The essay discusses the importance and prominence of theories about different stages of life in the anthropological and medical discourse of romanticism. This discourse has clearly a stabilising and restaurative function, favouring the age of moderate manhood. The political and social regulative implications of these theories demand a restaurative roll‐back. The essay is based on a concept of sociology of knowledge formation.     

Die Seele auf der Bühne der Justiz. Die Entstehung der Kriminalpsychologie im 19. Jahrhundert und ihre interdisziplinäre Erforschung

The mind on the stage of justice: The formation of criminal psychology in the 19th century and its interdisciplinary research. – Criminal psychology emerges at the end of the 18th century as a new academic discipline in lectures and publications. It has recently been investigated by a considerable number of contributions from researchers of different academic backgrounds. In many respects criminal psychology can be seen as a predecessor of criminology. Its subject is the analysis of the origins of crime and its causes and determinants in the human mind. Criminal psychology embraced at that time philosophical, medical, legal and biological aspects. The latter increase in importance in the second half of the 19th century. The conditions of individual responsibility were generally codified in penal law, but had to be individually investigated in crucial cases through expertise in court. There a conflict emerged between medical experts and judges about their ability and competence to decide. At the end of the 19th century criminal psychology is used to fulfil the needs and interests of a criminal law which understands itself as increasingly utilitarian. Force and new instruments of treatment of offenders were legitimized by scientists who were very optimistic about their own epistemological abilities.
