Mathematik und Religion in der frühen Neuzeit

Some protestant Mathematicians had a strong preoccupation with the Day of Judgement. Stifel, Faulhaber, Napier and Newton made calculations in order to determine the date of the end of the world. Craig gave mathematical rules for a decline in the reliability of Christian tradition; in order to prevent a reliability of nearly zero, the Day of Judgement must come before. Furthermore, some conflicts between theology and mathematics are discussed. The Council of Konstanz condemned Wyclif's theory of the continuum. It seems that the relation between part and whole was a crucial point between the Aristotelians and the “moderns”.     

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.     

Zur frühen Geschichte der Paläocheloniologie von Schaumburg‐Lippe. Die Rolle des Gymnasial‐Professors Max Ballerstedt in der Naturwissenschaft

A survey is given on some new aspects of the early history to the palaeochelonology in Schaumburg‐Lippe (Northern Germany). The very slow development of this is good reconstructable on base of authentic estates. It is the first time to made such a nearly complete reconstruction.
