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.     

Zeitpfeile,Zeitfaltungen und Diskursanalyse: zu Kontinuitäten der Imaginationslehre

Time Lines, Folded Time, and Discourse Analysis: Continuities of Maternal Imagination. Focusing on a discourse‐oriented history of knowledge, this article deals with the relation between continuity and time. It will discuss concepts of linear and homogenous time and problematize a one‐sided focus on discontinuity and rupture in discourse analyses. After examining notions of continuity, discontinuity, and temporality in the work of Michel Foucault, I will ask how continuous elements can be theorized both as instruments and objects of research, without adopting a linear concept of time. Thus, Michel Serres' concept of folded time will be presented, because it implies a multiple, heterogenous and non‐linear temporality and entails both continuous and discontinuous entities. Thereby relations of power should be considered as factors influencing the shape of the folding. In this way, folded time can serve as a useful tool for discourse analysis, enabling to examine specific and local continuities that vary in different discursive formations. To give an example, I will briefly turn to the concept of women's imagination in pregnancy. According to most historical analyses, this concept declined in the middle of the 18^th century and persisted afterwards only as an outdated remainder in folk knowledge. Nevertheless, a closer examination reveals that knowledge on imagination was actively produced in medical advice literature and some scientific discourses until the first decades of the 20^th century. This demonstrates that an overemphasis both on rupture and on the timeline of academic medicine might conceal continuous elements and the folded time of specific knowledge formations.     

Silvesterbesinnung und Weihnachtsartikel. Jahresendzeitreflexionen großer Physiker des 20. Jahrhunderts

The article deals with the relationship between science and religion (esp. Christian faith) in two articles of physicists Max Planck and Pascual Jordan. The relationship of the two factors is reflected in the treatment of time, a subject that comes up because both articles were written on the occasion of the year's end or even the end of a decade. By analysing the two perspectives on time it is possible to distil the distinctive ideas of Planck and Jordan on religion and how a religious should be related to a scientific world view. From this two different models of a positive relationship of science and religion can be formulated which transcend the framework of present discussions on the subject. In conclusion a possible role of science of religions in the dialogue between science and religion is described.
