Flat and Curved Space-Times

The present book explains special relativity and the basics of general relativity from a geometric viewpoint. Space-time geometry is emphasized throughout, and provides the basis of understanding of the special relativity effects of time dilation, length contraction, and the relativity of simultaneity. Bondi's K-calculus is introduced as a simple means of calculating the magnitudes of these effects, and leads to a derivation of the Lorentz transformation as a way of unifying these results. The invariant interval of flat space-time is generalised to that of curved space-times, and leads to an understanding of the basic properties of simple cosmological models and of the collapse of a star to form a black hole. The appendices enable the advanced student to master the application of four-tensors to the relativistic study of energy and momentum, and of electromagnetism. In addition, this new edition contains up-to-date information on black holes, gravitational collapse, and cosmology.

An extremely powerful witch from the times of Camelot, begins traveling the multiverse in a pursuit of power. Mankind's only hope lies in the hands of two teenage orphans and their misfit group of friends. Kevin and Marvin have been kidnapped; their home is no longer the safe haven it once was. Max and Simone are still dealing with the aftermath of their last battle, their team is battered and bruised. Moral is getting low; can they rescue their friends and find comfort in each other again or is this the end for their group of Outsiders? It's going to take a lot of soul searching, some therapy, and maybe even an outburst or two to bring this group back together, and they better do it quick before Circe strikes again.
