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 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 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.

Book excerpt: It's late in the 21st century and bioengineering is now so common that people are able to modify their minds in any way they wish. It is an era which has been shaped by information systems so vast that security, in any form, is easily breached. Now you can be whatever you want to be, and do whatever you want to do. On Earth anyway. One night, thirty three years ago, the stars went out. 'The Bubble' - a perfect sphere centred on the sun - appeared in the sky, isolating the solar system from the rest of the universe. For thirty-three years, humanity has lived with the religious cults and terrorism which spawned in the wake of the darkness. We are now alone. Humanity has been cut off. Quarantined.

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 Incandescence written by Greg Egan and published by Hachette UK. This book was released on 2011-06-10 with total page 233 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.

Book excerpt: Cass has stumbled on something that might be an entirely different type of physics, and she's travelled three hundred and fifty light-years to Mimosa Station, a remote experimental facility, to test her theory. The novo-vacuum she creates is predicted to begin decaying the instant it's created, but even so short-lived a microscopic speck could shed new light on the origins of the universe. But instead of decaying, Cass's novo-vacuum is wildly successful and begins expanding, slowly but inexorably taking over the universe ...

Download or read book Perihelion Summer written by Greg Egan and published by Tordotcom. This book was released on 2019-04-16 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greg Egan's Perihelion Summer is a story of people struggling to adapt to a suddenly alien environment, and the friendships and alliances they forge as they try to find their way in a world where the old maps have lost their meaning. Taraxippus is coming: a black hole one tenth the mass of the sun is about to enter the solar system. Matt and his friends are taking no chances. They board a mobile aquaculture rig, the Mandjet, self-sustaining in food, power and fresh water, and decide to sit out the encounter off-shore. As Taraxippus draws nearer, new observations throw the original predictions for its trajectory into doubt, and by the time it leaves the solar system, the conditions of life across the globe will be changed forever. Praise for Perihelion Summer “Egan here doubles down on climate change with his typically rigorous exploration of a cosmic accident’s effect on Earth and all its people. His characters are sharp and funny and their courageous response to the massive challenge they face works as a spur to cause us to think—why couldn’t we do as well with our own great challenge? This is what the best science fiction can do that no other genre can, and we need it now more than ever. Bravo!” — Kim Stanley Robinson At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

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: 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.
