This is the first volume in a series of books on democratic consolidation in Eastern Europe. The series focuses on three major aspects of democratic consolidation in Eastern Europe: institutional engineering, transnational pressures and civil society. This first volume analyses constraints on and opportunities of institutional engineering in Eastern Europe: to what extent and how elites in Eastern Europe have been able to shape, if not manipulate, the politics ofdemocratic consolidation through institutional means.The aim is to contrast a set of democracy theories with empirical evidence accumulated in Eastern Europe over the last ten years. The volume tries to avoid complex debates about definitions, methods and the uses and misuses of comparative research. Instead it tries to establish what has really happened in the region, and which of the existing theories have proved helpful in explaining these developments.The volume starts with a presentation of conceptual and comparative frameworks, followed by in-depth empirical analyses of the thirteen individual countries undergoing democratic consolidation. The first conceptual and comparative part contains three chapters. The first chapter explains what institutional engineering is about and describes our experiences with institutional engineering in former transitions to democracy. It also focuses on the import and export of institutional designs. Thesecond chapter analyses the utility of constitutions in the process of democratic consolidation. The third chapter compares constitutional designs and problems of implementation in Southern and Eastern Europe. The empirical case studies deal with the following countries: Estonia, Latvia, Lithuania,Bulgaria, Romania, Ukraine, Russia, Belarus, the Czech Republic, Slovakia, Slovenia, Hungary and Poland. And the conclusions evaluate the enormous impact of institutions on politics in Eastern Europe and show how central constitutional designs are to the institutional engineering in the societies undergoing transitions to democracy.Relativistic cosmology has in recent years become one of the most exciting and active branches of current research. In conference after conference the view is expressed that cosmology today is where particle physics was forty years ago, with major discoveries just waiting to happen. Also gravitational wave detectors, presently under construction or in the testing phase, promise to open up an entirely novel field of physics. It is to take into account such recent developments, as well as to improve the basic text, that this second edition has been undertaken. The most affected is the last part on cosmology, but there are smaller additions, corrections, and additional exercises throughout. The books basic purpose is to make relativity come alive conceptually. Hence the emphasis on the foundations and the logical subtleties rather than on the mathematics or the detailed experiments per se. Aided by some 300 exercises, the book promotes a deep understanding and the confidence to tackle any fundamental relativistic problem.
