A fully quantum-mechanical description of the spontaneous emission from an excited two-level atom placed in front of a two-slit interferometer is given. Global modes of the electromagnetic field in a two slit system are derived within the Kirchhoff-Huygens diffraction approximation, serving as a base for the field quantization. The standard Fermi's golden rule, supplemented by a factor coming from the nontrivial mode structure caused by the presence of the two-slit interferometer, is used to show that interference results from the position-dependent (...) coupling between the atom and different field modes of the system.

This article investigates the grammatical aspects of nominalization and the Japanese da predicate as critical strategies for realizing the effect of what I call `rhetorical ricochet' in Japanese discourse. The study explores the expressive function of the nominal/nominalizer and da in 28 imaginary letters appearing in asahi Shimbun as well as a literary text along with its English translation. I conclude that the combination of a certain kind of nominal/nominalizer and the da predicate reinforces the topic-comment relationship, through which the (...) rhetorical ricochet effect is realized. This article draws from theories on rhetoric and discourse functionalism, and the concept of shared perspectives, in particular. (shrink)

Problems connected with the questions of: being-nonbeing, existence, modes of existence and alike, belong to the basic and most important in metaphysics. The article discusses some answers to the aforementioned issues, as proposed by the ancient philosophers, St Thomas Aquinas, R. Ingarden and A.N. Whitehead. In the Appendix some remarks are made on Aristotle’s and S. Thomas’ theory of act and potency.
