Modern Theoretical and Observational Cosmology: Proceedings of the 2nd Hellenic Cosmology Meeting, held in the National Observatory of Athens , Penteli, 19–20 April 2001

The collection of presentations in this volume represents a satisfying balance between the rich subjects into which cosmology has matured over the past decades. First, the contributions of the `Architects' discuss fundamental cosmology , focusing on the topology and geometry of our Universe and the fundamental physical laws and processes in the Very Early Universe. Next, the `Constructors' discuss the ultimate realization of the cosmic framework with the recent determinations of the cosmological parameters which characterize the Friedmann-Robertson-Walker metric. Finally, the `Interior Decorators' take care of the cosmic infrastructure , some concentrating on the work of gravity, some responsible for the formation of the megaparsec cosmic structure while others are heroically trying to combine gravitational, hydrodynamic, radiative, stellar, and a variety of other dissipative processes into a courageous attempt towards understanding the lights in the cosmos.
