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.     

Über deutsch‐ungarische Beziehungen der Medizin im Zeitalter der Aufklärung ‐ zugleich ein Beitrag zur Geschichte der Pestinokulation

The influence of German science and medicine on the development of Hungarian medicine in the age of Enlightenment has been extraordinary strong. Many Hungarian medical students staid in German medical faculties. The medical interrelationships between Germany and Hungary in the 18^th century are discussed in an overview according to following dimensions: education of protestant Hungarian medical students at German »Aufklaerungs‐Universitaeten«, practical and theoretical resonance, membership of scientific societies, personal contacts and correspondence. Outstanding personalities of this aera were Daniel Fischer, István Weszprémi, Abraham Vater. Special attention is given to a new idea: inoculation against plague as first described by A. Vater in his work Blattern‐Beltzen (1721). Thirty years later I. Weszprémi published his original conception ‐ independently from Vater ‐ in the Tentamen de inoculanda peste (1755).     

“Die wissenschaftliche Ausbildung des Arztes ist eine Culturfrage …”. Über das Verhältnis von Wissenschaftsanspruch,Bildungsprogramm und Praxis der Medizin

The article shows that the elite, nationalistic and imperial mentality of German medicine in the second half of the nineteenth century was closely connected to its aim to be understodd as a natural science. With this in view leading representatives of German medicine propagated a scientific approach to man and nature instead of the traditional values of humanistic education (“Bildung”). One of the most important consequences of the new scientific ideal in medicine — integration in governmental planning, the change in professionel status of doctors, the increasing tendeny to recognize biologistic ideologies — was the loss of the medical ideal of the ars medica, a subject which has not received sufficient thematic attention. This theme is explored in the third part of the article.     

“Gedankenaustausch über Probleme und Methoden der Forschung”. Transatlantische Gastprofessoren aus Emigrantenkreisen in Westdeutschland nach 1945

The history of the sciences and humanities follows cycles in some of which there is greater emphasis on the continuity of developments, in others on the breaks in continuity. In recent years the main focus of research for the 20^th century has been on the continuities extending beyond the boundaries of 1933 and 1945. The main aim of this study, however, is to examine the impulses for the internationalization of German universities provided by a transnational group of academic migrants. These migrants, whose origins were in the German academic community, represented an alternative continuity beyond the boundaries of this period: they were visiting academics who were the conveyors and interpreters of ideas from Germany into the USA and Britain and vice versa. The study of this group therefore combines remigration history and the history of universities as institutions, focussing on actors, networks and innovations in teaching, with the history of individual subjects and disciplines.     

Theophrast über Pflanzenkrankheiten. Ein Beitrag zur Geschichte der Phytopathologie in der Antike

Already before Theophrastus there was a botanical literature which also dealt with the diseases of plants, but we have only indirectly access to it — mainly by way of Theophrastus. The botanical excursus of the Hippocratic series of writings De genitura, De natura pueri, De morbis IV, which attributes the health of plants to a balance of warmth and cold and a correct quantity of specific humidity, forms an exception. This excursus hints at what is more fully developed in Theophrastus discussion of the diseases of plants: The diseases of plants are understood in close analogy to those of animals or human beings. In both cases, a basic distinction is made between inner, dietetic diseases and outer, traumatic ones. According to Theophrastus, especially humidity and an innate warmth are life-sustaining factors. A disturbance of the natural humidity/warmth-household must be counteracted by respective measures. As far as the terminology of plant diseases is concerned, Theophrastus relies on already existing concepts. Classical literature after Theophrastus has made no substantial contributions to phytopathology.     

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.     

“Hungry for Knowledge”: Towards a Meso‐History of the Environmental Sciences

In recent years, cultural studies and cultural theory have experienced a new wave of ecological thought. Despite the engagement with the Anthropocene the history of ecology and the environmental sciences has remained somewhat of a puzzle. This goes especially for the 20^th century, a period when the sciences of the environment came to matter on a broader scale. Why do we actually know so little about the environmental sciences in the 20^th century? And what could a history of the environmental sciences in that period look like? This article answers these questions with two interrelated arguments. First, by reflecting on different approaches to write the history of ecology since the 1970s, it uncovers crucial entanglements between the history of science and ecological thought that created blind spots regarding the environmental sciences in the 20^th century. Second, it argues for a shift in scales of analysis—towards meso‐scales. With a more regional approach historians can engage with the often‐neglected aspects of the political and economic history of the environmental sciences in the 20th century and thereby also reveal their fundamental infrastructural dimension. Because at its core, the article claims, the environmental sciences were and are essentially infrastructural sciences.     

Historical limits: narrowing possibilities in ‘Ontario's most historic town’

Place branding in heritage tourism development is presented as a strategy that opens up new possibilities for attracting investors and visitors by distilling, capturing and shaping what is distinctive about a place. This representational fix is an efficient marketing device in the sense that it represents places through widely intelligible symbols. Branding is also a limiting activity that locks places in time and class relations. While place branding has always had this dual effect, we argue that it has particularly insidious and limiting consequences for local development under current conditions of roll‐out neoliberalism. Beginning in the 1960s, several prominent residents and outsiders initiated efforts to transform the Town of Cobalt, Ontario, into a mining heritage tourism destination. In 2001, the town entered and won a contest to be named Ontario's Most Historic Town. The following year it persuaded Parks Canada to designate it as a national historic site. These two events provided renewed external validation for the efforts to brand Cobalt as a heritage site and began a new cycle of mining heritage tourism development. However, instead of breaking the dependency relationships that characterize resource regions, the current round of place branding has acted to circumscribe the range of possible economic development options.     

Präzision versus Exaktheit: Konfligierende Ideale der angewandten mathematischen Forschung: Das Beispiel der Tragflügeltheorie

It is often supposed that mathematical argument provides a model of precision for the sciences. In contrast to this view, the present article proposes to distinguish between mathematical exactness as a (historically variable) ideal regulating the inner standards of mathematical argumentation and precision as a (historically variable) norm governing the relation between products of mathematical reasoning in scientific contexts and empirical or practical data. By discussing a major achievement in the mathematization of flight, Ludwig Prandtl's lifting line theory of wings, it is shown that exact reasoning does not necessarily lead to scientific precision, and that the achievement of precision may even require to loosen existing standards of exactness. It is argued that the main contribution of mathematical argument to generating precision in science lies in its capacity to provide sophisticated tools for the production of data, rather than in its adherence to an ideal of exactness.     

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.     

‘Born in an atomic test tube’: landscapes of cyclonic development at Uranium City,Saskatchewan

Drawing together insights from neo‐Innisian geography and environmental history, this paper explores the landscape and environmental changes engendered by ‘cyclonic’ patterns of development associated with uranium production at Uranium City, Saskatchewan. Strong postwar demand for uranium led to the establishment and rapid expansion of Uranium City on the north shore of Lake Athabasca as a ‘yellowcake town’, dedicated to producing uranium oxide concentrate to supply federal government contracts with the US military. In spite of optimistic assessments for the region's industrial future, the new settlement remained inherently unstable, tied to shifting institutional arrangements and external markets, and haunted by the spectre of resource depletion. The planning and development of the townsite at Uranium City reflected both neocolonial desires to open the north to Euro‐Canadian settlement and efforts by the state to buffer the stormy effects of resource dependency. Ultimately, however, quixotic government efforts to implant an outpost of industrial modernity in the Athabasca Region failed to forestall the inevitable winds of change, which left in their wake destructive legacies of social dislocation and environmental degradation, already evident with the near‐collapse of the uranium export market by the early 1960s.     

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 Grippe‐Pandemie 1918–20 in der medizinischen Debatte

The Influenza Pandemic of 1918–20 in medical debate. The history of the so called Spanish Influenza 1918–1920 is summarized especially in regard to the developments in medical debate. In Germany, Richard Pfeiffer, who had discovered Haemophilus influenzae after the previous pandemic 1890 / 91, managed it to defend his thesis that his “bacillus” was the causative agent of the flu, by modifying his theory moderately. The Early Virology of influenza in postwar times was still fixed to bacteriology and did not yet have the force of school‐building. Aggressive therapy, e.g. with derivatives of chinine, were used in a concept of polypragmasy. The connection between influenza in animals and influenza in mankind was unknown or of no major interest till the rise of virology as an academic discipline in the 1950s. Since the outbreak of avian influenza in Asia 1997 virological archaeology is challenged to fill the historical part in the attempt to fight the threat of the highly pathogenic bird flu. In the beginning of the “short 20. century” politicians and doctors had no interest to build a “monument” of influenza. Today, virological reductionism does not have the power to (re‐)construct such a monument.     

Refractions and recombinations of the ‘economic’ and the ‘social’: a personalized reflection on challenges by—and to—feminist urban geographies

This invited essay responds to requests by the Suzanne Mackenzie Memorial Lecture Nominating Committee and by the former Editor of this journal to take stock of and provide intellectual‐historical context for the major preoccupations that characterized feminist urban geography in its early years, by means of a personalized reflection in light of the author's own positioning in those debates and interventions. The thread running through the article is that of the relationship between the ‘economic’ and the ‘social’ in urban geography. The last section briefly considers new challenges that neoliberalism poses for critical feminist urban geographies.     

Weighted Bidimensional Regression. 加权二维回归

Shape analysis is useful for a wide variety of disciplines and has many applications. One of the many approaches to shape analysis focuses on shapes that are represented by predefined landmarks on an object. Some landmarks may be measured with greater precision, exhibit more natural variation, or be more important than others to an analysis. This article introduces a method for including this information when estimating mapping relations or assessing the degree of similarity between two objects that are represented by a set of two‐dimensional landmarks. Weighted bidimensional regression combines aspects of weighted least squares regression and bidimensional regression as a way to weight variables that are represented by a set of two‐dimensional spatial coordinates. One possible weighting scheme is suggested, and the effect of weighting is demonstrated through a face‐matching application. Results indicate that appropriate weighting increases the ability to correctly match two faces and that weighting has the largest effect when used with a projective transformation.     

Adaptive Cell Tower Location Using Geostatistics. 基于地统计学的适应性基站发射塔选址研究

In this article, we address the problem of allocating an additional cell tower (or a set of towers) to an existing cellular network, maximizing the call completion probability. Our approach is derived from the adaptive spatial sampling problem using kriging, capitalizing on spatial correlation between cell phone signal strength data points and accounting for terrain morphology. Cell phone demand is reflected by population counts in the form of weights. The objective function, which is the weighted call completion probability, is highly nonlinear and complex (nondifferentiable and discontinuous). Sequential and simultaneous discrete optimization techniques are presented, and heuristics such as simulated annealing and Nelder–Mead are suggested to solve our problem. The adaptive spatial sampling problem is defined and related to the additional facility location problem. The approach is illustrated using data on cell phone call completion probability in a rural region of Erie County in western New York, and accounts for terrain variation using a line‐of‐sight approach. Finally, the computational results of sequential and simultaneous approaches are compared. Our model is also applicable to other facility location problems that aim to minimize the uncertainty associated with a customer visiting a new facility that has been added to an existing set of facilities.     

Erschöpfte Literatur. Über das Neue bei Samuel Beckett

Exhausted Literature. The Emergence of the New in Samuel Beckett's Novels and Plays. The article investigates literary subjectivity in some texts by Samuel Beckett. The article proceeds by relating the ways of how narration and speech acts constitute literary subjectivity to the problems of subjectivity that scientific investigations deal with. While successful self‐regulation of the organism nourishes the roots of subjectivity, i. e. the habits, subjectivity decomposes in states of exhaustion, when self‐regulation breaks down. As soon as a certain threshold is transgressed, fatigue sets in, alters the personality and eventually leads to exhaustion – a state, which psychiatrists compare to mental illness. Notwithstanding the different explanations given, scientists agreed about the effects of exhaustion. According to their investigations, the decomposition of personality by exhaustion generally does not involve apathy, withdrawal from activity or termination of movements, but rather mere action. Similarly, in Beckett's novels and plays exhaustion is much more than tiredness, as French philosopher Gilles Deleuze observed. For Beckett, exhaustion is rather the model for both literary innovation and a new concept of subjectivity, which he explores on the basis of a detailed knowledge of physiology, psychology, and psychiatry, but using his own literary means. The exhausted subject is beyond any calculus of activity. It will perform an activity even if he or she makes mistakes or loses control, and will thus act in an unpredictable way. This unpredictable action is not an exception in the continuation of the habits, but rather points to the moment when a new subjectivity emerges. Such new subjectivity surfaces in Beckett's novels and plays in forms of literary innovation.     

„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?     

WHITE,FRIEDLÄNDER, “… AND THE REST IS HISTORY”: A PAX HISTORIANA

Close analysis of the ostensive disagreement between Saul Friedländer and Hayden White on the necessarily literary character of Holocaust historiography shows instead of conflict two compatible and even mutually supportive emphases in that project: the assumption in modernist and disruptive narratives as elsewhere of a “corpus of facts,” together with the role of figurative discourse in conveying relevant features of events that linear chronological or causal narratives alone do not convey.
