Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, how travel to the future is not only possible but has already happened, and he contemplates whether travel to the past is also conceivable. Notable not only for its extraordinary subject matter and scientific brilliance, Time Travel in Einstein’s Universe is a delightful and captivating exploration of the surprising facts behind the science fiction of time travel.

    Dick. The result is brilliantly original fiction as profund as it is playful. Now in his new novel, David Mitchell explores with daring artistry fundamental questions of reality and identity.Cloud Atlas begins in 1850 with Adam Ewing, an American notary voyaging from the Chatham Isles to his home in California. Along the way, Ewing is befriended by a physician, Dr. Goose, who begins to treat him for a rare species of brain parasite. . . .Abruptly, the action jumps to Belgium in 1931, where Robert Frobisher, a disinherited bisexual composer, contrives his way into the household of an infirm maestro who has a beguiling wife and a nubile daughter. . . . From there we jump to the West Coast in the 1970s and a troubled reporter named Luisa Rey, who stumbles upon a web of corporate greed and murder that threatens to claim her life. . . . And onward, with dazzling virtuosity, to an inglorious present-day England; to a Korean superstate of the near future where neocapitalism has run amok; and, finally, to a postapocalyptic Iron Age Hawaii in the last days of history.But the story doesn’t end even there. The narrative then boomerangs back through centuries and space, returning by the same route, in reverse, to its starting point. Along the way, Mitchell reveals how his disparate characters connect, how their fates intertwine, and how their souls drift across time like clouds across the sky.As wild as a videogame, as mysterious as a Zen koan, Cloud Atlas is an unforgettable tour de force that, like its incomparable author, has transcended its cult classic status to become a worldwide phenomenon.

    But Lister didn't have a choice. All he remembered was going on a birthday celebration pub crawl through London. When he came to his senses again, with nothing in his pockets but a passport in the name of Emily Berkenstein.So he did the only thing he could. Amazed to discover they would actually hire him, he joined the space corps----and found himself aboard Red Dwarf, a spaceship as big as a small city that, six or seven years from now, would get him back to Earth. What Lister couldn't forsee was that he'd inadvertently signed up for a one--way jaunt three million years into the future---a future which would see him the last living member of the human race, with only a hologram crew mate and a highly evolved cat for company. Of course, that was before the ship broke the light barrier and things began to get really weird...

    Thassadit Amzwar's blissful exuberance both entrances and puzzles the melancholic Russell. How can this refugee from perpetual terror be so happy? Won't someone so open and alive come to serious harm? Wondering how to protect her, Russell researches her war-torn country and skims through popular happiness manuals. Might her condition be hyperthymia? Hypomania? Russell's amateur inquiries lead him to college counselor Candace Weld, who also falls under Thassa's spell. Dubbed Miss Generosity by her classmates, Thassa's joyful personality comes to the attention of the notorious geneticist and advocate for genomic enhancement, Thomas Kurton, whose research leads him to announce the genotype for happiness.Russell and Candace, now lovers, fail to protect Thassa from the growing media circus. Thassa's congenital optimism is soon severely tested. Devoured by the public as a living prophecy, her genetic secret will transform both Russell and Kurton, as well as the country at large.What will happen to life when science identifies the genetic basis of happiness? Who will own the patent? Do we dare revise our own temperaments? Funny, fast, and finally magical, Generosity celebrates both science and the freed imagination. In his most exuberant book yet, Richard Powers asks us to consider the big questions facing humankind as we begin to rewrite our own existence.

    Not even politicians lie, and weirdly frank notices abound—such as warning: this elevator maintained by people who hate their jobs: ride at your own risk. In this dystopia of mandatory candor, every preadolescent citizen is ruthlessly conditioned, through a Skinnerian ordeal called a “brainburn,” to speak truthfully under all circumstances.Jack Sperry wouldn’t dream of questioning the norms of Veritas; he’s happy with his life and his respectable job as a “deconstructionist,” destroying “mendacious” works of art—relics from a less honest era. But when his adored son, Toby, falls gravely ill, the truth becomes Jack’s greatest enemy. Somehow our hero must overcome his brainburn and attempt to heal his child with beautiful lies.

    For mathematicians, physicists, engineers, and everyone else with an interest in mathematics' cutting edge, The Millennium Problems is the definitive account of a subject that will have a very long shelf life.

    In How Not to Be Wrong, Jordan Ellenberg shows us how terribly limiting this view is: Math isn’t confined to abstract incidents that never occur in real life, but rather touches everything we do—the whole world is shot through with it.Math allows us to see the hidden structures underneath the messy and chaotic surface of our world. It’s a science of not being wrong, hammered out by centuries of hard work and argument. Armed with the tools of mathematics, we can see through to the true meaning of information we take for granted: How early should you get to the airport? What does “public opinion” really represent? Why do tall parents have shorter children? Who really won Florida in 2000? And how likely are you, really, to develop cancer?How Not to Be Wrong presents the surprising revelations behind all of these questions and many more, using the mathematician’s method of analyzing life and exposing the hard-won insights of the academic community to the layman—minus the jargon. Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, what Facebook can and can’t figure out about you, and the existence of God.Ellenberg pulls from history as well as from the latest theoretical developments to provide those not trained in math with the knowledge they need. Math, as Ellenberg says, is “an atomic-powered prosthesis that you attach to your common sense, vastly multiplying its reach and strength.” With the tools of mathematics in hand, you can understand the world in a deeper, more meaningful way. How Not to Be Wrong will show you how.

    Next challenges our sense of reality and notions of morality. Balancing the comic and bizarre with the genuinely frightening and disturbing, Next shatters our assumptions, and reveals shocking new choices where we least expect.The future is closer than you think. Get used to it.

    He provides readers with non-trivial insights into research fields they may not have encountered previously . . . I think everyone who has ever considered the possibility that other intelligent civilizations exist elsewhere within our galaxy will enjoy Where Is Everybody? They will find much to agree with, and much to argue about, in this very accessible volume.� �SCIENCE During a Los Alamos lunchtime conversation that took place more than 50 years ago, four world-class scientists agreed, given the size and age of the Universe, that advanced extraterrestrial civilizations simply had to exist. The sheer numbers demanded it. But one of the four, the renowned physicist and back-of-the-envelope calculator Enrico Fermi, asked the telling question: If the extraterrestrial life proposition is true, he wondered, "Where IS everybody?" In this lively and thought-provoking book, Stephen Webb presents a detailed discussion of the 50 most cogent and intriguing answers to Fermi's famous question, divided into three distinct groups: - Aliens are already here among us. Here are answers ranging from Leo Szilard's suggestion that they are already here, and we know them as Hungarians, to the theorists who claim that aliens built Stonehenge and the Easter Island statues. - Aliens exist, but have not yet communicated. The theories in this camp range widely, from those who believe we simply don't have the technologies to receive their signals, to those who believe the enormities of space and time work against communication, to those who believe they're hiding from us. - Aliens do not exist. Here are the doubters' arguments, from the Rare Earth theory to the author's own closely argued and cogently stated skepticism. The proposed solutions run the gamut from the crackpot to the highly serious, but all deserve our consideration. The varieties of arguments -- from first-rate scientists, philosophers and historians, and science fiction authors -- turn out to be astonishing, entertaining, and vigorous intellectual exercises for any reader interested in science and the sheer pleasure of speculative thinking. Stephen Webb is a physicist working at the Open University in England and the author of Measuring the Universe.

    It is God without men.- Honoré de Balzac, Une passion dans le désert, 1830 Jaz and Lisa Matharu are plunged into a surreal public hell after their son, Raj, vanishes during a family vacation in the California desert. However, the Mojave is a place of strange power, and before Raj reappears inexplicably unharmed - but not unchanged - the fate of this young family will intersect with that of many others, echoing the stories of all those who have traveled before them. Driven by the energy and cunning of Coyote, the mythic, shapeshifting trickster, Gods Without Men is full of big ideas, but centered on flesh-and-blood characters who converge at an odd, remote town in the shadow of a rock formation called the Pinnacles. Viscerally gripping and intellectually engaging, it is, above all, a heartfelt exploration of the search for pattern and meaning in a chaotic universe.

    What's more, it knows the Earth is dying.Deep in Western Australia where the Aboriginals used to milk the trees, a planet-sized plot is taking shape. Some green freaks pick up the scent: a pommie poseur; a brain-fried Vietnam vet; Aboriginals who have lost their land...not much against a conspiracy that controls society. But EcoAction isn't in society: it just lives in the same place, along with the cockroaches.If you're facing the richest and most disgusting scheme in history, you have to do more than stick up two fingers and say 'peace'.

    The science of complexity studies how single elements, such as a species or a stock, spontaneously organize into complicated structures like ecosystems and economies; stars become galaxies, and snowflakes avalanches almost as if these systems were obeying a hidden yearning for order. Drawing from diverse fields, scientific luminaries such as Nobel Laureates Murray Gell-Mann and Kenneth Arrow are studying complexity at a think tank called The Santa Fe Institute. The revolutionary new discoveries researchers have made there could change the face of every science from biology to cosmology to economics. M. Mitchell Waldrop's groundbreaking bestseller takes readers into the hearts and minds of these scientists to tell the story behind this scientific revolution as it unfolds.

    His prodigious early work clouded his reputation and strained his sanity. But an old friend gives him another chance, an opportunity to step back into the light.With three months to produce new research, Eric replicates the paradoxical double-slit experiment to see for himself the mysterious dual nature of light and matter. A simple but unprecedented inference blooms into a staggering discovery about human consciousness and the structure of the universe.His findings are celebrated and condemned in equal measure. But no one can predict where the truth will lead. And as Eric seeks to understand the unfolding revelations, he must evade shadowy pursuers who believe he knows entirely too much already.

    Gardner's array of absorbing puzzles and mind-twisting paradoxes opens mathematics up to the world at large, inspiring people to see past numbers and formulas and experience the application of mathematical principles to the mysterious world around them. With articles on topics ranging from simple algebra to the twisting surfaces of Mobius strips, from an endless game of Bulgarian solitaire to the unreachable dream of time travel, this volume comprises a substantial and definitive monument to Gardner's influence on mathematics, science, and culture.In its twelve sections, The Colossal Book of Math explores a wide range of areas, each startlingly illuminated by Gardner's incisive expertise. Beginning with seemingly simple topics, Gardner expertly guides us through complicated and wondrous worlds: by way of basic algebra we contemplate the mesmerizing, often hilarious, linguistic and numerical possibilities of palindromes; using simple geometry, he dissects the principles of symmetry upon which the renowned mathematical artist M. C. Escher constructs his unique, dizzying universe. Gardner, like few thinkers today, melds a rigorous scientific skepticism with a profound artistic and imaginative impulse. His stunning exploration of "The Church of the Fourth Dimension," for example, bridges the disparate worlds of religion and science by brilliantly imagining the spatial possibility of God's presence in the world as a fourth dimension, at once "everywhere and nowhere."With boundless wisdom and his trademark wit, Gardner allows the reader to further engage challenging topics like probability and game theory which have plagued clever gamblers, and famous mathematicians, for centuries. Whether debunking Pascal's wager with basic probability, making visual music with fractals, or uncoiling a "knotted doughnut" with introductory topology, Gardner continuously displays his fierce intelligence and gentle humor. His articles confront both the comfortingly mundane—"Generalized Ticktacktoe" and "Sprouts and Brussel Sprouts"—and the quakingly abstract—"Hexaflexagons," "Nothing," and "Everything." He navigates these staggeringly obscure topics with a deft intelligence and, with addendums and suggested reading lists, he informs these classic articles with new insight.Admired by scientists and mathematicians, writers and readers alike, Gardner's vast knowledge and burning curiosity reveal themselves on every page. The culmination of a lifelong devotion to the wonders of mathematics, The Colossal Book of Mathematics is the largest and most comprehensive math book ever assembled by Gardner and remains an indispensable volume for the amateur and expert alike.
