Technology doesn't flow smoothly; it's the big surprises that matter, and Yale computer expert David Gelernter sees one such giant leap right on the horizon. Today's small scale software programs are about to be joined by vast public software works that will revolutionize computing and transform society as a whole. One such vast program is the "Mirror World." Imagine looking at your computer screen and seeing reality--an image of your city, for instance, complete with moving traffic patterns, or a picture that sketches the state of an entire far-flung corporation at this second. These representations are called Mirror Worlds, and according to Gelernter they will soon be available to everyone. Mirror Worlds are high-tech voodoo dolls: by interacting with the images, you interact with reality. Indeed, Mirror Worlds will revolutionize the use of computers, transforming them from (mere) handy tools to crystal balls which will allow us to see the world more vividly and see into it more deeply. Reality will be replaced gradually, piece-by-piece, by a software imitation; we will live inside the imitation; and the surprising thing is--this will be a great humanistic advance. We gain control over our world, plus a huge new measure of insight and vision. In this fascinating book--part speculation, part explanation--Gelernter takes us on a tour of the computer technology of the near future. Mirror Worlds, he contends, will allow us to explore the world in unprecedented depth and detail without ever changing out of our pajamas. A hospital administrator might wander through an entire medical complex via a desktop computer. Any citizen might explore the performance of the local schools, chat electronically with teachers and other Mirror World visitors, plant software agents to report back on interesting topics; decide to run for the local school board, hire a campaign manager, and conduct the better part of the campaign itself--all by interacting with the Mirror World. Gelernter doesn't just speculate about how this amazing new software will be used--he shows us how it will be made, explaining carefully and in detail how to build a Mirror World using technology already available. We learn about "disembodied machines," "trellises," "ensembles," and other computer components which sound obscure, but which Gelernter explains using familiar metaphors and terms. (He tells us that a Mirror World is a microcosm just like a Japanese garden or a Gothic cathedral, and that a computer program is translated by the computer in the same way a symphony is translated by a violinist into music.) Mirror Worlds offers a lucid and humanistic account of the coming software revolution, told by a computer scientist at the cutting edge of his field.

A glorious epic fantasy in the grand tradition of CS Lewis and Philip Pullman, and a major publishing event, The Mirror Chronicles will take you into another world, and on the adventure of your lifetime...

An ambitious tale of magic, war, and parallel worlds that pushes the boundaries of epic fantasy—from a two-time Hugo Award winner On the eve of a recurring catastrophic event known to extinguish nations and reshape continents, a troubled orphan evades death and slavery to uncover her own bloody past . . . while a world goes to war with itself. In the frozen kingdom of Saiduan, invaders from another realm are decimating whole cities, leaving behind nothing but ash and ruin. At the heart of this war lie the pacifistic Dhai people, once enslaved by the Saiduan and now courted by their former masters to provide aid against the encroaching enemy. As the dark star of the cataclysm rises, an illegitimate ruler is tasked with holding together a country fractured by civil war; a precocious young fighter is asked to betray his family to save his skin; and a half-Dhai general must choose between the eradication of her father's people or loyalty to her alien Empress. Through tense alliances and devastating betrayal, the Dhai and their allies attempt to hold against a seemingly unstoppable force as enemy nations prepare for a coming together of worlds as old as the universe itself. In the end, one world will rise—and many will perish. Stretching from desolate tundras to steamy, semi-tropical climes seething with sentient plant life, this is an epic tale of blood mages and mercenaries, emperors and priestly assassins, who must unite to save a world on the brink of ruin.

The kingdom of the Isles is in the throes of a magical upheaval that causes the ocean to recede, a situation that reveals the Isles to be a high ground on a broader continent with past and future ties.

In the mid-1990s, astronomers made history when they began to find planets orbiting stars in the Milky Way. More than eight hundred planets have been found since then, yet none of them is anything like Earth and none could support life. Now, armed with more powerful technology, planet hunters are racing to find a true twin of Earth. Science writer Michael Lemonick has unique access to these exoplaneteers, as they call themselves, and Mirror Earth unveils their passionate quest. Unlike competitors in other races, Geoff Marcy, Bill Borucki, David Charbonneau, Sara Seager, and others actually consult and cooperate with one another. But only one will be the first to find Earth's twin. Mirror Earth tells the story of their competition.

A “rock star” (New York Times) of the computing world provides a radical new work on the meaning of human consciousness. The holy grail of psychologists and scientists for nearly a century has been to understand and replicate both human thought and the human mind. In fact, it's what attracted the now-legendary computer scientist and AI authority David Gelernter to the discipline in the first place. As a student and young researcher in the 1980s, Gelernter hoped to build a program with a dial marked "focus." At maximum "focus," the program would "think" rationally, formally, reasonably. As the dial was turned down and "focus" diminished, its "mind" would start to wander, and as you dialed even lower, this artificial mind would start to free-associate, eventually ignoring the user completely as it cruised off into the mental adventures we know as sleep. While the program was a only a partial success, it laid the foundation for The Tides of Mind, a groundbreaking new exploration of the human psyche that shows us how the very purpose of the mind changes throughout the day. Indeed, as Gelernter explains, when we are at our most alert, when reasoning and creating new memories is our main mental business, the mind is a computer-like machine that keeps emotion on a short leash and attention on our surroundings. As we gradually tire, however, and descend the "mental spectrum," reasoning comes unglued. Memory ranges more freely, the mind wanders, and daydreams grow more insistent. Self-awareness fades, reflection blinks out, and at last we are completely immersed in our own minds. With far-reaching implications, Gelernter’s landmark "Spectrum of Consciousness" finally helps decode some of the most mysterious wonders of the human mind, such as the numinous light of early childhood, why dreams are so often predictive, and why sadism and masochism underpin some of our greatest artistic achievements. It’s a theory that also challenges the very notion of the mind as a machine—and not through empirical studies or "hard science" but by listening to our great poets and novelists, who have proven themselves as humanity's most trusted guides to the subjective mind and inner self. In the great introspective tradition of Wilhelm Wundt and René Descartes, David Gelernter promises to not only revolutionize our understanding of what it means to be human but also to help answer many of our most fundamental questions about the origins of creativity, thought, and consciousness.

Theirs is a world of opposites. The privileged live in sky manors held aloft by a secretive magic known only as the Mysteries. Below, the earthbound poor are forced into factory work to maintain the engine of commerce. Only the wealthy can afford to learn the Mysteries and they use their knowledge to further lock their hold on society. Cettie Pratt is a waif doomed to the world below until an admiral attempts to adopt her. But in her new home in the clouds, not everyone treats her as one of the family. Sera Fitzempress is a princess born into power. She yearns to meet the orphan girl she has heard so much about but her father deems the girl unworthy of his daughter's curiosity. Neither girl feels that she belongs. Each seeks to break free of imposed rules. Now, as Cettie dreams of living above and as Sera is drawn to the world below, they will follow the paths of their own choosing. But both girls will be needed for the coming storm that threatens to overturn both their worlds.
