A crazy man swears vengeance on bad mathematicians! In this diabolical math based murder mystery.

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.

An introduction to awe-inspiring ideas at the brink of paradox: infinities of different sizes, time travel, probability and measure theory, and computability theory. This book introduces the reader to awe-inspiring issues at the intersection of philosophy and mathematics. It explores ideas at the brink of paradox: infinities of different sizes, time travel, probability and measure theory, computability theory, the Grandfather Paradox, Newcomb's Problem, the Principle of Countable Additivity. The goal is to present some exceptionally beautiful ideas in enough detail to enable readers to understand the ideas themselves (rather than watered-down approximations), but without supplying so much detail that they abandon the effort. The philosophical content requires a mind attuned to subtlety; the most demanding of the mathematical ideas require familiarity with college-level mathematics or mathematical proof. The book covers Cantor's revolutionary thinking about infinity, which leads to the result that some infinities are bigger than others; time travel and free will, decision theory, probability, and the Banach-Tarski Theorem, which states that it is possible to decompose a ball into a finite number of pieces and reassemble the pieces so as to get two balls that are each the same size as the original. Its investigation of computability theory leads to a proof of Gödel's Incompleteness Theorem, which yields the amazing result that arithmetic is so complex that no computer could be programmed to output every arithmetical truth and no falsehood. Each chapter is followed by an appendix with answers to exercises. A list of recommended reading points readers to more advanced discussions. The book is based on a popular course (and MOOC) taught by the author at MIT.

Earth’s time is running out. Sixty years ago a plan was conceived to help humanity survive its first contact with an alien race. Now it’s time to put that plan to the test. No country can stand alone. The world must unite if there is to be any hope of survival. Commander Kaylan Farrow and her crew are investigating an ancient alien signal from beyond the fringes of known space. After months of searching, the Athena is starting to wear down. It’s only a matter of time before a catastrophic failure destroys their ship, but if they return to Earth now, Kaylan knows that humanity will not survive their first contact with hostile aliens. They must find the source of the signal and with it a means to end this war before it has a chance to reach Earth. Infinity’s Edge is the fourth book in the Ascension space opera series. The crew of the Athena will risk everything to unravel the mystery of an ancient alien race whose wars nearly destroyed the galaxy. On Earth, people must accept that the world as they knew it is gone. The Xiiginns are coming to pull Earth into the crosshairs of an interstellar war.

A commonly encountered experience of both analyst and analysand is that of the void. It is spoken about at different stages of therapy and refers to experiences that have different origins. Sometimes the experience of the void is around a relatively limited aspect of the psyche but at other times the void seems much more global and threatens to engulf the entire personality; the whole individual psyche then seems threatened by the possibility of dissolution into nothingness.
