Manifold Origin

2015: Astronaut Reid Malenfant is flying over the African continent, intent on examining a mysterious glowing construct in Earth’s orbit.

“Reading Manifold: Time is like sending your mind to the gym for a brisk workout. If you don’t feel both exhausted and exhilirated when you’re done, you haven’t been working hard enough.”—The New York Times Book Review The year is 2010. More than a century of ecological damage, industrial and technological expansion, and unchecked population growth has left the Earth on the brink of devastation. As the world’s governments turn inward, one man dares to envision a bolder, brighter future. That man, Reid Malenfant, has a very different solution to the problems plaguing the planet: the exploration and colonization of space. Now Malenfant gambles the very existence of time on a single desperate throw of the dice. Battling national sabotage and international outcry, as apocalyptic riots sweep the globe, he builds a spacecraft and launches it into deep space. The odds are a trillion to one against him. Or are they? “A staggering novel! If you ever thought you understood time, you’ll be quickly disillusioned when you read Manifold: Time.”—Sir Arthur C. Clarke

“One of the best SF writers in the business . . . [Manifold: Origin is] filled with marvelous scientific speculations, strange events, novel concepts, and an awe-inspiring sense of the wonders of the universe.”—Science Fiction Chronicle In the year 2015, astronaut Reid Malenfant is flying over the African continent, intent on examining a mysterious glowing construct in Earth’s orbit. But when the very fabric of the sky tears open, spilling living creatures to the ground and pulling others inside (including his wife, Emma), Malenfant’s quest to uncover the unknown becomes personal. While desperately searching to discover what happened to the woman he loves, Malenfant embarks upon an adventure to the very fount of human development . . . on earth and beyond.

In the year 2570, a sleeper will wake . . . In the mid-21st century, the Kernel, a strange object on a five-hundred-year-orbit, is detected coming from high above the plane of the solar system. Could it be an alien artefact? In the middle of climate-change crises, there is no mood for space-exploration stunts - but Reid Malenfant, elderly, once a shuttle pilot and frustrated would-be asteroid miner, decides to go take a look anyway. Nothing more is heard of him. But his ex-wife, Emma Stoney, sets up a trust fund to search for him the next time the Kernel returns . . . By 2570 Earth is transformed. A mere billion people are supported by advanced technology on a world that is almost indistinguishable from the natural, with recovered forests, oceans, ice caps. It is not an age for expansion; there are only small science bases beyond the Earth. But this is a world you would want to live in: a Star Trek without the stars. After 500 years the Kernel returns, and a descendant of Stoney, who Malenfant will call Emma II, mounts a mission to see what became of Malenfant. She finds him still alive, cryo-preserved . . . His culture-shock encounter with a conservative future is entertaining . . . But the Kernel itself turns out to be attached to a kind of wormhole, through which Malenfant and Emma II, exploring further, plummet back in time, across five billion years . . .

Tied in to Baxter's masterful Manifold trilogy, these thematically linked stories are drawn from the vast graph of possibilities across which the lives of hero Reid Malenfant have been scattered. It is the year 2025. Reid Malenfant is the commander of a NASA earth-orbiting science platform. The platform is intended to probe the planets of the nearest star system by bouncing laser pulses off them. But no echoes are returned... and Malenfant's reality begins to crumble around him. Huddling with his family, awaiting the end -- or an unknown new beginning -- Malenfant tells stories of other possibilities, other realities. The linked stories encompass the myriad possibilities that might govern our relationship with the universe: are we truly alone, or will we eventually meet other lifeforms? Perhaps intelligent species decide to turn their back on the stars, or maybe expansionist species are destined to fail. The final possibility -- that the Universe as we know it is in fact an elaborate illusion designed to protect us from the fearful reality -- is brilliantly explored in the tour de force novella that ends the volume.

Manifolds, the higher-dimensional analogs of smooth curves and surfaces, are fundamental objects in modern mathematics. Combining aspects of algebra, topology, and analysis, manifolds have also been applied to classical mechanics, general relativity, and quantum field theory. In this streamlined introduction to the subject, the theory of manifolds is presented with the aim of helping the reader achieve a rapid mastery of the essential topics. By the end of the book the reader should be able to compute, at least for simple spaces, one of the most basic topological invariants of a manifold, its de Rham cohomology. Along the way, the reader acquires the knowledge and skills necessary for further study of geometry and topology. The requisite point-set topology is included in an appendix of twenty pages; other appendices review facts from real analysis and linear algebra. Hints and solutions are provided to many of the exercises and problems. This work may be used as the text for a one-semester graduate or advanced undergraduate course, as well as by students engaged in self-study. Requiring only minimal undergraduate prerequisites, 'Introduction to Manifolds' is also an excellent foundation for Springer's GTM 82, 'Differential Forms in Algebraic Topology'.

“Magisterial and uplifting . . . A brilliant, grandscale sampling of sixty-five million years of human evolution . . . It shows the sweep and grandeur of life in its unrelenting course.” —The Denver Post Stretching from the distant past into the remote future, from primordial Earth to the stars, Evolution is a soaring symphony of struggle, extinction, and survival; a dazzling epic that combines a dozen scientific disciplines and a cast of unforgettable characters to convey the grand drama of evolution in all its awesome majesty and rigorous beauty. Sixty-five million years ago, when dinosaurs ruled the Earth, there lived a small mammal, a proto-primate of the species Purgatorius. From this humble beginning, Baxter traces the human lineage forward through time. The adventure that unfolds is a gripping odyssey governed by chance and competition, a perilous journey to an uncertain destination along a route beset by sudden and catastrophic upheavals. It is a route that ends, for most species, in stagnation or extinction. Why should humanity escape this fate? Praise for Evolution “Spectacular.”—The New York Times Book Review “Strong imagination, a capacity for awe, and the ability to think rigorously about vast and final things abound in the work of Stephen Baxter. . . . [Evolution] leaves the reader with a haunting portrayal of the distant future.”—Times Literary Supplement “A breath of fresh air . . . The miracle of Evolution is that it makes the triumph of life, which is its story, sound like the real story.”—The Washington Post Book World

It's the year 2030. The oceans have risen rapidly, and soon the entire planet will be submerged. But the discovery of another life-sustaining planet light years away gives those who remain alive hope. Only a few will be able to make the journey-Holle Groundwater is one of the candidates. If she makes the cut, she will live. If not, she will be left to face a watery death...
