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.     

Karl der Große,Alkuin und die Zeitrechnung

In connection with the Carolingian renewal of education Charlemagne also cared for a homogeneous reckoning of time. He organized the Carolingian reform of the calender with the help of Alkuin of York, an Anglo‐Saxon scholar. Having heard of Alkuin's learning and teaching abilities, the Frankish King invited him to lead his Palace school at Aachen. Moving to Francia 782, Alkuin became the key counselour of Charlemagne for science, education and church matters. Among other subjects Alkuin taught the King especially calendrical reckoning (computus) and astronomy, in which he took a special personal interest. Charlemagne discussed these subjects often with Alkuin, sometimes even in letters, still preserved today. For this correspondence on astronomy and calendrical reckoning it was assumed that Alkuin was the author of four short anonymous writings on computus. Moreover, Charlemagne comissioned Alkuin to write a standard work on computus, which is lost today. But three Carolingian manuals on computus survived. Which of the four anonymous writings really stem from Alkuin himself? What influence he had upon the manuals? These two questions are investigated here on the basis of the most important matter of computus: the calculation of the age of the moon in the 19‐year lunar cycle, necessary for dating the movable feast of Easter (on the first Sunday after the first full moon in spring). These facts were discussed in detail, even vehemently, in the correspondence between Alkuin and Charlemagne.     

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.     

Oszillierende Weltmodelle versus Urknallmodelle. Das oszillierende Weltmodell Friedmanns,die Ablehnung der Anfangssingularität durch russische Kosmologen und die Zustimmung der katholischen Kirche zur Urknalltheorie Lemaîtres und Hawkings

The Russian mathematician and physicist Friedmann and the Belgian priest and physicist Lemaître were the first to consider non‐static world models in the framework of Einstein's general theory of relativity. Friedmann seemed to favour a periodic, oscillating cosmological model. His investigations were taken up by Russian cosmologists in the 1960s. They stated that the singularities present in many of the Friedmann‐Lemaître cosmological models seemed to be artificial and were ascribed to the assumption of a highly symmetric distribution of cosmic matter. Their disapproval of singularities seems to be in accord with Soviet ideological requirements during that time like atheism and dialectic materialism. They had to retract their statements after Hawking had proved his singularity theorems and after the microwave background had been discovered. Hawking followed the line of thought which was initiated by Lemaître in the early 1930s. Lemaître had combined for the first time quantum physics and relativistic cosmology and had developed his idea of the primeval atom, a beginning of the universe in a dense state with just one quantum containing the whole mass of the universe. Pope Pius XII brought together this primeval atom and God as the Creator of the universe and declared in 1951 that big bang cosmology is compatible with the Bible. Not surprisingly Hawking was awarded the Pius XI medal by the Vatican in 1975 for his contributions to big bang cosmology.     

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.     

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.     

Sigmund Freud und die Lauterkeit

In his carrier as physician, Sigmund Freud claimed various and surprising successes in healing patients. An evaluation of those cases in which evidence independent of Freud's publications has been discovered reveals a lifelong pattern of Freud claiming successes, patients, however, not being cured, and Freud being aware of this. The elements of this pattern are matched with the components of the legal definition of fraud.     

Thomas Kuhn und die Wissenschaftsgeschichte

The article discusses Thomas S. Kuhn's impact on the history of science, especially in the United States of America. First, the state of the history of science in the fifties is sketched. Second, Kuhn's particular contribution to the emerging new historiography of science is presented. Third, Kuhn's role in the m‐stitutionalization of the history of science in the USA is considered. Finally, some remarks are made on the relation between Kuhn's historiographic work and his book The Structure of Scientific Revolutions.     

Justinian I. und die Patriarchate Rom und Konstantinopel

In Auseinandersetzung mit einigen neueren Beiträgen (Andreae, Görler) sucht der Verf. die Schwierigkeiten im Abschnitt über die Laokoongruppe aufzuzeigen und zu lösen. Er behandelt dabei u.a. den logischen Zusammenhang, den Sinn von nec plures pariter nuncupari possunt, die Beziehung von sicut in Laocoonte zum Ganzen und nicht zuletzt die Bedeutung der Apposition opus omnibus ... praeferendum. Das Ergebnis der Analyse bestätigt wichtige Elemente der traditionellen Deutung.
