In classical philosophy of time, present time mainly has been considered in its fleetingness: it is transition, in the Platonic meaning of the sudden or in the Aristotelian sense of discreet moment and isolated intensity that escapes possible perception. Through the idea of subjective constitution of time, Husserl’s phenomenology tries to spread the moment. He transcends the idea of linear and empty time in modern philosophy. Phenomenological description of time experience analyses the filled character of the moment that can be detained in the performance of consciousness. As a consequence of the temporality of consciousness, he nevertheless remains in the temporal conception of presence. The phenomenology of Merleau-Ponty, however, is able to grasp the spacial meaning of presence. In his perspective of a phenomenology of perception, presence can be understood as a space surrounding the body, as a field of present things given in perception. Merleau-Ponty recovers the ancient sense of ‘praesentia’ as a fundamental concept of being in the world.

Данная работа посвящена исследованию процессов глубокого анизотропного травления кремния. В качестве предложенных методов были проанализированы два подхода - Bosch и Cryo. Представлено феноменологическое описание вышеупомянутых методов, проведен анализ эксперимента по криогенному травлению кремния, полученный на базе ФТИАН, также предложена аналитическая модель Cryo-процесса. This work is devoted to the study of the processes of deep anisotropic silicon etching. Two approaches (Bosch and Cryo) have been analyzed as proposed methods. The phenomenological description of the above mentioned methods has been presented, the analysis of the experiment on cryogenic etching of silicon obtained on the basis of FTIAN has been carried out, as well as an analytical model of Cryo process has been proposed.

Electromagnetic Radiation is a graduate level book on classical electrodynamics with a strong emphasis on radiation. This book is meant to quickly and efficiently introduce students to the electromagnetic radiation science essential to a practicing physicist. While a major focus is on light and its interactions, topics in radio frequency radiation, x-rays, and beyond are also treated. Special emphasis is placed on applications, with many exercises and homework problems. The format of the book is designed to convey the basic concepts of a topic in the main central text in the book in a mathematically rigorous manner, but with detailed derivations routinely relegated to the accompanying side notes or end of chapter “Discussions.” The book is composed of four parts: Part I is a review of basic E&M, and assumes the reader has a had a good upper division undergraduate course, and while it offers a concise review of topics covered in such a course, it does not treat any given topic in detail; specifically electro- and magnetostatics. Part II addresses the origins of radiation in terms of time variations of charge and current densities within the source, and presents Jefimenko’s field equations as derived from retarded potentials. Part III introduces special relativity and its deep connection to Maxwell’s equations, together with an introduction to relativistic field theory, as well as the relativistic treatment of radiation from an arbitrarily accelerating charge. A highlight of this part is a chapter on the still partially unresolved problem of radiation reaction on an accelerating charge. Part IV treats the practical problems of electromagnetic radiation interacting with matter, with chapters on energy transport, scattering, diffraction and finally an illuminating, application-oriented treatment of fields in confined environments.

This chapter reviews Dreyfus’s hermeneutical methodology, and the constant interplay between phenomenological description and textual interpretation in his work. It explains why Dreyfus always philosophizes in a kind of dialogue with thinkers in the history of philosophy, and how he interprets these thinkers in such a way as to illuminate through their works contemporary problems in philosophy. It then offers a theory of Dreyfus’s understanding of practices, before reviewing the concept of a background practice as it functions in Dreyfus’s work. For Dreyfus, the background practices embodied in a culture are the key to making sense of the understanding of being that grounds a world.

Hubert Dreyfus is one of the foremost advocates of European philosophy in the anglophone world. His clear, jargon-free interpretations of the leading thinkers of the European tradition of philosophy have done a great deal to erase the analytic–Continental divide. But Dreyfus is not just an influential interpreter of Continental philosophers; he is a creative, iconoclastic thinker in his own right. Drawing on the work of Heidegger, Husserl, Merleau-Ponty, Foucault, and Kierkegaard, Dreyfus makes significant contributions to contemporary conversations about mind, authenticity, technology, nihilism, modernity and postmodernity, art, scientific realism, and religion. This volume collects thirteen of Dreyfus’s most influential essays, each of which interprets, develops, and extends the insights of his predecessors working in phenomenological and existential philosophy. The essays exemplify a distinctive feature of his approach to philosophy, namely the way his work inextricably intertwines the interpretation of texts with his own analysis and description of the phenomena at issue. In fact, these two tasks—textual exegesis and phenomenological description—are for Dreyfus necessarily dependent on each other. In approaching philosophy in this way, Dreyfus is an heir to Heidegger’s own historically oriented style of phenomenology.

Everyday aesthetics is often criticized for lacking aesthetic credentials. Its legitimacy as a discourse is questioned because proximal senses, experiences gained while engaging in an activity, and qualities other than beauty and sublimity are included in its purview. Inclusion of these items is considered to deny a clear ‘object’ of aesthetic appreciation, the possibility of objective judgments, and profundity of aesthetic experience. Excluding them, however, does not do justice to the rich and multifaceted contents of everyday aesthetic life. Phenomenological description, instead of the judgment-oriented and objectivity-seeking discourse, is more appropriate for exploring some dimensions of everyday aesthetic life. In addition, while possibly lacking the same degree of profundity and intensity of beauty and sublimity, the popular appeal of easily recognizable aesthetic qualities deserves to be investigated because of their prevalence and frequent manipulation for commercial and political purposes.
