Effectively diagrammed and with an emphasis on logical structure, Sartori's rigorous but simple presentation will guide interested readers through concepts of relative time and relative space. He covers general relativity and cosmology, and focuses on Einstein's theory. He tracks its history and implications. He explores illuminating paradoxes, including the famous twin paradox, the'pole-in-the-barn' paradox, and the Loedel diagram, which is a graphic approach to relativity. Copyright (C) Muze Inc. 2005.
