In the historiography of mathematics the concept of deviation is relative to a normal way of developing mathematics. Similarly, the concept of abbreviation is necessarily connected to some aim to which this development is directed. We should not speak of deviation or abbreviation without regard for such contects. In the history of mathematics there are some cases of treating impossible objects as possible objects of a new theory. Therefore it may be expected that there are more ways out than in (...) normal life. Some examples are given. *** DIRECT SUPPORT *** A02GD002 00011. (shrink)

The starting-point is the distinction between concept and conception. Our conceptions of gold, for instance, are the different understandings we get when we hear the word ‘gold’ whereas the concept of gold consists in the scientific determination of what gold is. It depends on the context whether it is more reasonable to claim a concept or to look for fitting conceptions. By arguing against metaphysical realism and for non-metaphysical realism, I will elaborate on some philosophical reasons for dealing with conceptions (...) instead of concepts of God, and secondly, I will discuss how such conceptions should be critically assessed.

In 1675, Leibniz elaborated his longest mathematical treatise he everwrote, the treatise ``On the arithmetical quadrature of the circle, theellipse, and the hyperbola. A corollary is a trigonometry withouttables''. It was unpublished until 1993, and represents a comprehensive discussion of infinitesimalgeometry. In this treatise, Leibniz laid the rigorous foundation of thetheory of infinitely small and infinite quantities or, in other words,of the theory of quantified indivisibles. In modern terms Leibnizintroduced `Riemannian sums' in order to demonstrate the integrabilityof continuous functions. The (...) article deals with this demonstration,with Leibniz's handling of infinitely small and infinite quantities,and with a general theorem regarding hyperboloids. (shrink)

In view of the scope and scale of the latest scandals, e.g. Enron's maximum breaking bankruptcy, the re-discovery of ethics in business has received an impressive boost. By now even car salesmen have written ethics, a Code of Conduct, e.g. in the USA or Poland. But there is no clear aim of the role ethics obtains in organizational settings as we may show in some small cases of practical approaches to deal with ethics in organizations. We discuss how ethics is (...) the prerequisite to conduct any business and what advantages may be realized if a clear set of ethics is followed. We will discuss three practical examples. In cases of ethics-based values-added management of Siemens (Germany), Boeing (U.S.) and SAP (Germany) we explain the mechanisms of ethics in management to strengthen organizational success. We emphasize the importance of clear ethics-related communication processes in organizations. We explain the use of communication theories inside organizational processes to clarify communication about such an abstract topic as ethics. Finally, we point out how a management of ethical ideas and cultural values should be designed in business enterprises. (shrink)

La cessation hebdomadaire du travail le dimanche est de plus en plus contestée dans notre société. Si les exigences économiques rendent nécessaire le fonctionnement ininterrompu des machines, il faudrait assurer à chaque employé un autre jour de repos. Peut-on alors définir le dimanche comme jour de repos commun à la majorité de la société ? Les chrétiens ont l’habitude de se prononcer en faveur du repos dominical en rappelant le commandement du Décalogue : «Observe le jour du sabbat ». Or (...) cet argument n’est pas pertinent pour des raisons historiques et herméneutiques. Il est toutefois possible de tirer de ce commandement, en particulier de sa version deutéronomique (Dt 5,12-15), des arguments susceptibles d’enrichir les débats d’aujourd’hui. (shrink)

On the Lisbon earthquake of 1755; its effects on thinking of the time.

Darwin proposed that evolutionary novelties are environmentally induced in organisms “constitutionally” sensitive to environmental change, with selection effective owing to the inheritance of constitutional responses. A molecular theory of inheritance, pangenesis , explained the cross‐generational transmission of environmentally induced traits, as required for evolution by natural selection. The twentieth‐century evolutionary synthesis featured mutation as the source of novelty, neglecting the role of environmental induction. But current knowledge of environmentally sensitive gene expression, combined with the idea of genetic accommodation of mutationally (...) and environmentally induced change, supports a revival of Darwin's original theory that is consistent with modern molecular and population genetics. †To contact the author, please write to: Smithsonian Tropical Research Institute, c/o Escuela de Biología, Universidad de Costa Rica, Costa Rica; e‐mail: [email protected].
