With unequaled clarity, they explore t he work of the most famous unifier of all, Albert Einstein, who melded space and time into a combined space-time concept, and then embarked on an unsuccessful search for a...

A complete account of the fundamental techniques of general relativity and their application to cosmology.

The perturbations to the cosmological models are discussed throughout the volume. The cosmic microwave background is presented, with an emphasis in...
