Theurgy in Dionysius the Areopagite

The present chapter aims at offering insights into Dionysius the Areopagite’s notion of theurgy, both with respect to the metaphysical principles that connect with “θεουργία” and the particular sacramental reality that emerges from it. Pavlos argues that despite the linguistic affinities and terminological appropriations - whether Iamblichean or Proclean - Dionysius’ premises on the matter remain radically different from that of Neoplatonism, both in terms of the sacramental tradition he recapitulates and the wider Christian metaphysical contours he adheres to. Of central importance in the argument is the striking fact that, throughout the Corpus Dionysiacum, “theurgy” is a term exclusively used by the author to refer to the works of Christ in His earthly historical presence, and to the whole divine providential, creative, sustaining, and divinising activity and work of God. Consequently, if for Dionysius a “theurgist” (θεουργός) could not be any human being, but only Christ Himself, the God-Man, Dionysian theurgy aims at the deification of man, which is nothing other than Christ-likeness

Generation of J0 Bessel Beams with controlled spatial coherence features

An alternative method to generate J0 Bessel beams with controlled spatial partial coherence properties is introduced. Far field diffraction from a discrete number of source points on an annular region is calculated. The average for different diffracted fields produced at several rotation angles is numerically calculated and experimentally detected. Theoretical and experimental results show that for this particular case, J0 Bessel beam is a limit when the number of points tends towards infinity and the associated complex degree of coherence is also a function of the number of points.Comment: 6 pages, 5 figure

Obsah vzdělávání ve školních vzdělávacích programech

Příspěvek se zabývá obsahem současného předškolního vzdělávání, jak je vymezen v Rámcovém vzdělávacím programu pro předškolní vzdělávání v České republice. Jeho pojetí je nahlíženo v historickém kontextu. V empirické části příspěvek přibližuje závěry analýzy školních vzdělávacích programů pro předškolní vzdělávání zveřejněných na webových stránkách mateřských škol tří krajů České republiky. Poskytuje informace o formulování obsahu předškolního vzdělávání v jednotlivých mateřských školách. Z výsledků analýzy vyplývá, že nepřesné požadavky Rámcového vzdělávacího programu pro předškolní vzdělávání se odráží v úrovni zpracování obsahu vzdělávání ve školních vzdělávacích programech mateřských škol.This contribution deals with the content of the current pre-primary education, how it is defined in the Frame Educational Program for Pre-primary Education in the Czech Republic. Its conception is viewed in historical context. In the empirical part the contribution talks about the conclusions of analysis of school educational programs for pre-primary education published on website of kindergartens of three region of Czech Republic. It provides information about formulation of the content of pre-school education in individual kindergartens. From the analysis of the conclusions imply that imprecise requirements of the Frame Educational Program for Pre-primary Education in the Czech Republic are reflected in the level of processing of the content of education in school educational programs of kindergartens

Unraveling beam self-healing

We show that, contrary to popular belief, non only diffraction-free beams may reconstruct themselves after hitting an opaque obstacle but also, for example, Gaussian beams. We unravel the mathematics and the physics underlying the self-reconstruction mechanism and we provide for a novel definition for the minimum reconstruction distance beyond geometric optics, which is in principle applicable to any optical beam that admits an angular spectrum representation. Moreover, we propose to quantify the self-reconstruction ability of a beam via a newly established degree of self-healing. This is defined via a comparison between the amplitudes, as opposite to intensities, of the original beam and the obstructed one. Such comparison is experimentally accomplished by tailoring an innovative experimental technique based upon Shack-Hartmann wave front reconstruction. We believe that these results can open new avenues in this field
