The book, suitable as both an introductory reference and as a text book in the rapidly growing field of topological graph theory, models both maps (as in map-coloring problems) and groups by means of graph imbeddings on sufaces. Automorphism groups of both graphs and maps are studied. In addition connections are made to other areas of mathematics, such as hypergraphs, block designs, finite geometries, and finite fields. There are chapters on the emerging subfields of enumerative topological graph theory and random topological graph theory, as well as a chapter on the composition of English...

The 2012 Black Hole Killer (c) is a cross-genre murder-mystery/cosmological Bonfire of the Vanities novel about the predicted universe's end on December 21, 2012. The book begins with a seeming murder that occurs on July 28, 1977. The victim is floating in mid-air and frozen to the coldest temperature of the universe, absolute zero, when it's 95 degrees outside. The book then takes you to what happened the day before and next to the day after the body is discovered.

The plot centers around the travails of the Hindu Goddess Kali. Fourteen billion years old, She possesses all the powers of...
