Gheorghe Pascalau: Damaskios (gebundenes Buch)

Damaskios (ca. 462–538) ist der letzte originelle Metaphysiker der Antike. Sein Lebensweg führte ihn von Damaskus nach Alexandrien, wo er Rhetorik und Philosophie studierte, und sodann nach Athen, wo er zum Leiter der Platonischen Akademie aufstieg. Ein Edikt der römischen Obrigkeit, das den Andersdenkenden die Lehrtätigkeit untersagte, nötigte Damaskios zur Auswanderung an den persischen Königshof.

Syrien – Ägypten – Griechenland – Persien sind die Hauptstationen dieses sich im stetigen Wandel befindenden Lebensweges. Dabei ist Damaskios’ Philosophie in einer Theorie des ‚Unsagbaren‘ zentriert, die sich als Plädoyer für ein interreligiöses Gespräch verstehen lässt. Der Tagungsband führt Beiträge aus der Philosophie und Klassischen Philologie mit Stimmen aus der Alten Geschichte, Rechtsromanistik, Iranistik und Islamwissenschaft zu einer interdisziplinären Auseinandersetzung mit Damaskios’ Wirken und Denken zusammen.

The systematic exploration of thermodynamic properties of molten metals and the physical processes during melt solidification provide the basis to develop proper modeling tools for computer assisted materials design to optimize casting processes, production routes and even find novel and innovative materials. This handbook concentrates on multicomponent alloys because most of the metallic materials in daily use are composed of several elements. It covers important aspects from fundamentals to applications: Thermodynamics, Microscopic and Macroscopic Dynamics, NdFe based Alloys, Solidification and Simulation. The text provides a vital understanding of melt properties and solidification processes, treating all simulation techniques for continuous and discrete systems, such as molecular dynamics on an atomic scale and sharp interface and phase field modeling on a mesoscopic scale. This is a complete and detailed picture of complex simulation of metallic alloy melts and their solidification behaviour for materials scientists, solid state physicists and chemists, and those working in the metal processing industry. The reports given in the handbook describe scientific results of a priority program (DFG SPP1120) funded by the Deutsche Forschungsgemeinschaft over a period of six years.
