The masters of the Euchronian Millennium are panicking. The fabric of their ideal society on the platform built over the Earth has been ripped, and the order that they hold so precious seems to be teetering on the brink of collapse. In order to save it, the Hegemon has decided to obliterate all life in the perpetually covered Underworld of Earth from which the threat comes--but his followers are of two minds as to whether that's even possible, let alone justifiable. As the opposition grows, the plan goes forward--but then the Underworld begins to fight back, and everything's thrown into chaos: a chaos with which the citizens of a supposedly ideal society are simply not equipped to deal. Meanwhile, in the Underworld, the fight for survival goes on, as bitterly and ruthlessly as ever. The smashing conclusion to The Realms of Tartarus Trilogy!

ONE GIANT LEAP FOR MANKIND Those were Neil Armstrong’s immortal words when he became the first human being to step onto another world. All at once, the horizon expanded; the human race was no longer Earthbound. Edge of Infinity is an exhilarating new SF anthology that looks at the next giant leap for humankind: the leap from our home world out into the Solar System. From the eerie transformations in Pat Cadigan’s Hugo-award-winning “The Girl-Thing Who Went Out for Sushi” to the frontier spirit of Sandra McDonald and Stephen D. Covey’s “The Road to NPS,” and from the grandiose vision of Alastair Reynolds’ “Vainglory” to the workaday familiarity of Kristine Kathryn Rusch’s “Safety Tests,” the thirteen stories in this anthology span the whole of the human condition in their race to colonise Earth’s nearest neighbours. Featuring stories by Hannu Rajaniemi, Alastair Reynolds, James S. A. Corey, John Barnes, Stephen Baxter, Kristine Kathryn Rusch, Elizabeth Bear, Pat Cadigan, Gwyneth Jones, Paul McAuley, Sandra McDonald, Stephen D. Covey, An Owomoyela, and Bruce Sterling, Edge of Infinity is hard SF adventure at its best and most exhilarating.

Drawing on the science and mathematics of infinity, H. Chris Ransford analyzes the traditional concept of godhood and reaches surprising conclusions. He addresses humankind's abiding core debate on the meaning of spirituality and God. Using mathematics, he explores key questions within this debate: for instance, why does evil exist if there is a God? The book fastidiously does not take sides nor proffers opinions, it only follows allowable mathematics wherever it leads. By doing so, it makes a major contribution to an understanding of the nature of reality.

A dynamic exploration of infinity In Infinity and the Mind, Rudy Rucker leads an excursion to that stretch of the universe he calls the “Mindscape,” where he explores infinity in all its forms: potential and actual, mathematical and physical, theological and mundane. Using cartoons, puzzles, and quotations to enliven his text, Rucker acquaints us with staggeringly advanced levels of infinity, delves into the depths beneath daily awareness, and explains Kurt Gödel’s belief in the possibility of robot consciousness. In the realm of infinity, mathematics, science, and logic merge with the fantastic. By closely examining the paradoxes that arise, we gain profound insights into the human mind, its powers, and its limitations. This Princeton Science Library edition includes a new preface by the author.

Thirteen new stories by the celebrated writer, including two which he considers his greatest achievements to date, artfully blend elements from many literary geares.
