Heinz-Jürgen Schmidt - Böcker

This study presents a collection of research papers, written by physicists, philosophers and historians of science who had participated in the Zentrum fuer interdisziplinare Forschung (ZiF) during the academic year 1992/93 in order to discuss the nature and structure of spacetime as it is used in general relativity. All contributions focus on unsolved questions, such as the possibility of time machines, referential indeterminacy, the hole problem, and the conventional versus empirical character of spacetime. These papers deal with Einstein's view of general covariance and with the epistemological status of space(time) in the works of Carnap, Weyl and Hilbert, all of whom relate their position to Husserl's phenomenology, yet in fundamentally different ways.

The papers in this volume were presented at the colloquium "Reduktion in der Wissenschaft: Struktur, Beispiele, philos- ophische PrObleme", held in Bielefeld, West Germany, July 18- 21, 1983. Altogether eighteen talks were delivered at the symposium, and all appear here with the exception of Professor Ehlers' address. In addition, we are pleased to be able to include three papers by invited participants (Kamiah, Ludwig, Scheibe) who were unable to attend the meeting. The meeting itself brought together a sizeable group of logicians, philosophers and working scientists to discuss and debate the theme of reduction, one that occupies a central place in contemporary philosophy of science. The participants and contributors succeeded in opening up new directions in reduction studies and presenting fresh case studies of re- duction from many different areas of scientific practice. Their efforts will greatly enhance our understanding of reduction and, consequently, our grasp of the complex process of scien- tific change and the unity and growth of scientific knowledge.

This book presents a collection of research papers, written by physicists, philosophers and historians of science who had participated in the Zentrum fur interdisziplinare Forschung (ZiF) during the academic year 1992/93 in order to discuss the nature and structure of spacetime as it is used in general relativity. All contributions focus on unsolved questions, such as the possibility of time machines, referential indeterminacy, the hole problem, and the conventional vs. empirical character of spacetime. These papers having a more historical colour deal with Einstein's view of general covariance and with the epistemological status of space(time) in the works of Carnap, Weyl and Hilbert, all of whom relate their position to Husserl's phenomenology, yet in fundamentally different ways.
