REFLECTIONS ON SPACETIME - FOUNDATIONS, PHILOSOPHY AND HISTORY During the academic year 1992/93, an interdisciplinary research group constituted itself at the Zentrum fUr interdisziplinare Forschung (ZiF) in Bielefeld, Germany, under the title 'Semantical Aspects of Spacetime Theories', in which philosophers and physicists worked on topics in the interpretation and history of relativity theory. The present issue consists of contributions resulting from material presented and discussed in the group during the course of that year. The scope of the papers ranges from rather specialised issues arising from general relativity such as the problem of referential indeterminacy, to foundational questions regarding spacetime in the work of Carnap, Weyl and Hilbert. It is well known that the General Theory of Relativity (GTR) admits spacetime models which are 'exotic' in the sense that observers could travel into their own past. This poses a number of problems for the physical interpretation of GTR which are also relevant in the philosophy of spacetime. It is not enough to exclude these exotic models simply by stating that we live in a non-exotic universe, because it might be possible to "operate time machines" by actively changing the topology of the future part of spacetime. In his contribution, Earman first reviews the attempts of physicists to prove "chronology protection theorems" (CPTs) which exclude the operation of time machines under reasonable assumptions.

Research on medieval and early modern travel literature has made great progress, which now allows us to take the next step and to analyze the correlations between the individual and space throughout time, which contributed essentially to identity formation in many different settings. The contributors to this volume engage with a variety of pre-modern texts, images, and other documents related to travel and the individual's self-orientation in foreign lands and make an effort to determine the concept of identity within a spatial framework often determined by the meeting of various cultures. Moreover, objects, images and words can also travel and connect people from different worlds through books. The volume thus brings together new scholarship focused on the interrelationship of travel, space, time, and individuality, which also includes, of course, women's movement through the larger world, whether in concrete terms or through proxy travel via readings. Travel here is also examined with respect to craftsmen's activities at various sites, artists' employment for many different projects all over Europe and elsewhere, and in terms of metaphysical experiences (catabasis).
Gets to the heart of science by asking a fundamental question: what is the true nature of space and time?
C.S. Lewis presents an eloquent and colorful defense of Christianity for both devotees and critics . . . in a collection of essays composed over the last twenty years of his life. * On Christianity and culture * On religion -- is it reality or substitute? * On ethics * On the Psalms * On the language of religion * On petitionary prayer * And more! "An excellent introduction to the thought and personality of this engaging Christian writer." -- Christianity Today
The last two decades have seen two significant trends emerging within the philosophy of science: the rapid development and focus on the philosophy of the specialised sciences, and a resurgence of Aristotelian metaphysics, much of which is concerned with the possibility of emergence, as well as the ontological status and indispensability of dispositions and powers in science. Despite these recent trends, few Aristotelian metaphysicians have engaged directly with the philosophy of the specialised sciences. Additionally, the relationship between fundamental Aristotelian concepts—such as "hylomorphism", "substance", and "faculties"—and contemporary science has yet to receive a critical and systematic treatment. Neo-Aristotelian Perspectives on Contemporary Science aims to fill this gap in the literature by bringing together essays on the relationship between Aristotelianism and science that cut across interdisciplinary boundaries. The chapters in this volume are divided into two main sections covering the philosophy of physics and the philosophy of the life sciences. Featuring original contributions from distinguished and early-career scholars, this book will be of interest to specialists in analytical metaphysics and the philosophy of science.

Self-contained introduction to quantum groups as algebraic objects, suitable as a textbook for graduate courses.
Embark on a mind-bending journey through the realms of time and space in "Beyond the Horizon." This captivating exploration delves into the deepest mysteries of the universe, unraveling the enigmatic fabric of reality itself. From the tiniest subatomic particles to the vast expanse of the cosmos, this book delves into the fundamental questions that have puzzled humanity for centuries. What is time? Is it merely a construct of our perception, or does it hold a deeper, intrinsic meaning? And what of space? Is it truly infinite, or are there boundaries yet to be discovered? Through the lens of cutting-edge science and philosophy, "Beyond the Horizon" navigates the complexities of spacetime, offering readers a profound understanding of the interconnectedness of all things.
