Download or read book Permutation City written by Greg Egan and published by Greg Egan. This book was released on 1994-04-26 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paul Durham keeps making Copies of himself: software simulations of his own brain and body which can be run in virtual reality, albeit seventeen times more slowly than real time. He wants them to be his guinea pigs for a set of experiments about the nature of artificial intelligence, time, and causality, but they keep changing their mind and baling out on him, shutting themselves down. Maria Deluca is an Autoverse addict; she’s unemployed and running out of money, but she can’t stop wasting her time playing around with the cellular automaton known as the Autoverse, a virtual world that follows a simple set of mathematical rules as its “laws of physics”. Paul makes Maria a very strange offer: he asks her to design a seed for an entire virtual biosphere able to exist inside the Autoverse, modelled right down to the molecular level. The job will pay well, and will allow her to indulge her obsession. There has to be a catch, though, because such a seed would be useless without a simulation of the Autoverse large enough to allow the resulting biosphere to grow and flourish — a feat far beyond the capacity of all the computers in the world.

Book Synopsis The Best of Greg Egan by : Greg Egan
Download or read book The Best of Greg Egan written by Greg Egan and published by Gollancz. This book was released on 2021-03-18 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greg Egan is arguably Australia's greatest living science fiction writer. In a career spanning more than thirty years, he has produced a steady stream of novels and stories that address a wide range of scientific and philosophical concerns: artificial intelligence, higher mathematics, science vs religion, the nature of consciousness, and the impact of technology on the human personality. All these ideas and more find their way into this generous and illuminating collection, the clear product of a man who is both a master storyteller and a rigorous, exploratory thinker. The Best of Greg Egan contains twenty stories and novellas arranged in chronological order, and each of them is a brilliantly conceived, painstakingly developed gem, including the Hugo Award-winning novella "Oceanic", a powerful account of a boy whose deeply held religious beliefs are undermined by what he comes to learn about the laws of the physical world. This book really does represent the best of Greg Egan, and it therefore takes its place among the best of contemporary SF. Startling, intelligent and always hugely entertaining, it provides an ideal introduction to one of the most accomplished and original writers working today. This is an important and provocative collection, and it deserves a place on the serious science fiction reader's permanent shelf.
Download or read book Schild’s Ladder written by Greg Egan and published by Greg Egan. This book was released on 2002-02-21 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: For twenty thousand years, every observable phenomenon in the universe has been successfully explained by the Sarumpaet Rules: the laws governing the dynamics of the quantum graphs that underlie all the constituents of matter and the geometric structure of spacetime. Now Cass has stumbled on a set of quantum graphs that might comprise the fundamental particles of an entirely different kind of physics, and she has travelled three hundred and seventy light years to Mimosa Station, a remote experimental facility, in the hope of bringing this tantalising alternative to life. The “novo-vacuum” is predicted to begin decaying the instant it’s created, but even a short-lived, microscopic speck could shed light on the origins of the universe, and test the Sarumpaet Rules more rigorously than ever before. Cass’s experiment turns out to be more successful than anticipated: the novo-vacuum is more stable than the ordinary vacuum around it, and a region in which the new physics holds sway proceeds to expand out from Mimosa at half the speed of light. Six hundred years later, more than two thousand inhabited systems have been lost to the novo-vacuum. On the Rindler, a ship that has matched velocities with the encroaching border, people have come from throughout inhabited space to study the phenomenon. Most are Preservationists, hunting for a way to turn back the tide, but a few belong to another faction: Yielders, who believe that the challenge of adapting to survive on the far side of the border would reinvigorate a civilisation that has grown stale and insular. Tchicaya has come to the Rindler to join the Yielders, but when Mariama — a childhood friend whose example inspired him to abandon his own home world and traditions for a life of travel — arrives soon after, he is shocked to discover that she plans to help the Preservationists find a way to destroy the novo-vacuum. As a theoretical breakthrough leads to a sequence of experiments that begins to reveal the true richness of the world behind the border, tensions between the opposing factions grow. When a splinter group responds to these revelations with violent, unilateral action, Tchicaya and Mariama are forced into an uneasy alliance, and travel together through the border, balancing old and new loyalties against the fate of two incomparably different universes.

Book excerpt: In 2034, the stars went out. An unknown agency surrounded the solar system with an impenetrable barrier, concealing the universe from humanity’s gaze. In 2067, Nick Stavrianos is hired to investigate the disappearance of a mentally disabled woman, Laura Andrews, from the institution where she was being cared for. Aided by a skull full of neural modifications, he follows her trail to the Republic of New Hong Kong, where an organisation known as the Ensemble has uncovered Laura’s extraordinary secret: an ability that could transform the world.
Download or read book Diaspora written by Greg Egan and published by Greg Egan. This book was released on 1997-09-03 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2975, the orphan Yatima is grown from a randomly mutated digital mind seed in the conceptory of Konishi polis. Yatima explores the Coalition of Polises, the network of computers where most life in the solar system now resides, and joins a friend, Inoshiro, to borrow an abandoned robot body and meet a thriving community of “fleshers” in the enclave of Atlanta. Twenty-one years later, news arrives from a lunar observatory: gravitational waves from Lac G-1, a nearby pair of neutron stars, show that the Earth is about to be bathed in a gamma-ray flash created by the stars’ collision — an event that was not expected to take place for seven million years. Yatima and Inoshiro return to Atlanta to try to warn the fleshers, but meet suspicion and disbelief. Some lives are saved, but the Earth is ravaged. In the aftermath of the disaster, the survivors resolve to discover the cause of the neutron stars’ premature collision, and they launch a thousand polises into interstellar space in search of answers. This diaspora eventually reaches a planet subtly transformed to encode a message from an older group of travellers: a greater danger than Lac G-1 is imminent, and the only escape route leads beyond the visible universe.
Download or read book Greg Egan written by Karen Burnham and published by University of Illinois Press. This book was released on 2014-04-30 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greg Egan (1961- ) publishes works that challenge readers with rigorous, deeply-informed scientific speculation. He unapologetically delves into mathematics, physics, and other disciplines in his prose, putting him in the vanguard of the hard science fiction renaissance of the 1990s. A working physicist and engineer, Karen Burnham is uniquely positioned to provide an in-depth study of Egan's science-heavy oeuvre. Her survey of the author's career covers novels like Permutation City and Schild's Ladder and the Hugo Award-winning novella "Oceanic," analyzing how Egan used cutting-edge scientific theory to explore ethical questions and the nature of humanity. As Burnham shows, Egan's collected works constitute a bold artistic statement: that narratives of science are equal to those of poetry and drama, and that science holds a place in the human condition as exalted as religion or art. The volume includes a rare interview with the famously press-shy Egan covering his works, themes, intellectual interests, and thought processes.

Book excerpt: "Del lives in a world of many skies: by passing through the Hoops embedded in the ground, her people can walk freely between land that lies beneath a new set of constellations for every circuit they make around the edge of a Hoop. When archaeologists find a copy of the famed Book of All Skies, Del takes delivery of the manuscript in her role as conservator at the Museum of Apasa, hoping it will shed light on the fate of the Tolleans, the ancient civilisation that produced it. But when the book is stolen, the theft sets in motion a series of events that will see her travelling farther than she had ever imagined possible, and her understanding of her world and its history irrevocably transformed."--Amazon.com.
Download or read book Dichronauts written by Greg Egan and published by Start Publishing LLC. This book was released on 2017-07-11 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seth is a surveyor, along with his friend Theo, a leech-like creature running through his skull who tells Seth what lies to his left and right. Theo, in turn, relies on Seth for mobility, and for ordinary vision looking forwards and backwards. Like everyone else in their world, they are symbionts, depending on each other to survive. In the universe containing Seth's world, light cannot travel in all directions: there is a “dark cone” to the north and south. Seth can only face to the east (or the west, if he tips his head backwards). If he starts to turn to the north or south, his body stretches out across the landscape, and to rotate as far as north-north-east is every bit as impossible as accelerating to the speed of light. Every living thing in Seth’s world is in a state of perpetual migration as they follow the sun’s shifting orbit and the narrow habitable zone it creates. Cities are being constantly disassembled at one edge and rebuilt at the other, with surveyors mapping safe routes ahead. But when Seth and Theo join an expedition to the edge of the habitable zone, they discover a terrifying threat: a fissure in the surface of the world, so deep and wide that no one can perceive its limits. As the habitable zone continues to move, the migration will soon be blocked by this unbridgeable void, and the expedition has only one option to save its city from annihilation: descend into the unknown.
Download or read book The Clockwork Rocket written by Greg Egan and published by Hachette UK. This book was released on 2011-09-15 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Yalda's universe, light has mass, no universal speed, and its creation generates energy; on Yalda's world, plants make food by emitting light into the dark night sky. And time is different: an astronaut might measure decades passing while visiting another star, only to return and find that just weeks have elapsed for her friends. On the farm where she lives, Yalda sees strange meteors that are entering the planetary system at an immense, unprecedented speed - and it soon becomes apparent that more of this ultra-fast material is appearing all the time, putting her world in terrible danger. An entire galaxy is about to collide with their own. There is one hope: a fleet sent straight towards the approaching galaxy, as fast as possible. Though it will feel like weeks back home, on board, millennia will pass before the collision, time enough to raise new generations, and time enough to find a way to stop the ultra-fast material. Either way, they have a chance to save everyone back on the home world.
Download or read book Incandescence written by Greg Egan and published by Hachette UK. This book was released on 2011-06-10 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: A million years from now, the galaxy is divided between the vast, cooperative meta-civilisation known as the Amalgam, and the silent occupiers of the galactic core known as the Aloof. The Aloof have long rejected all attempts by the Amalgam to enter their territory, but have permitted travellers to take a perilous ride as unencrypted data in their communications network, providing a short-cut across the galaxy's central bulge. When Rakesh encounters a traveller, Lahl, who claims she was woken by the Aloof on such a journey and shown a meteor full of traces of DNA, he accepts her challenge to try to find the uncharted world deep in the Aloof's territory from which the meteor originated. Roi and Zak live inside the Splinter, a world of rock that swims in a sea of light they call the Incandescence. Living on the margins of a rigidly organised society, they seek to decipher the subtle clues that can reveal the true nature of the Splinter. In fact, the Splinter is orbiting a black hole, which is about to capture a neighbouring star, wreaking havoc. As the signs of danger grow, Roi, Zak, and a growing band of recruits struggle to understand and take control of their fate. Meanwhile, Rakesh is gradually uncovering their remote history, and his search for the lost DNA world ultimately leads him to a civilisation trapped in cultural stagnation, and startling revelations about the true nature and motives of the Aloof.
