Sean Carroll, theoretical physicist and one of this world’s most celebrated writers on science, rewrites the history of 20th century physics. Already hailed as a masterpiece, Something Deeply Hidden shows for the first time that facing up to the essential puzzle of quantum mechanics utterly transforms how we think about space and time. His reconciling of quantum mechanics with Einstein’s theory of relativity changes, well, everything. Most physicists haven’t even recognized the uncomfortable truth: physics has been in crisis since 1927. Quantum mechanics has always had obvious gaps—which have come to be simply ignored. Science popularizers keep telling us how weird it is, how impossible it is to understand. Academics discourage students from working on the "dead end" of quantum foundations. Putting his professional reputation on the line with this audacious yet entirely reasonable book, Carroll says that the crisis can now come to an end. We just have to accept that there is more than one of us in the universe. There are many, many Sean Carrolls. Many of every one of us. Copies of you are generated thousands of times per second. The Many Worlds Theory of quantum behavior says that every time there is a quantum event, a world splits off with everything in it the same, except in that other world the quantum event didn't happen. Step-by-step in Carroll's uniquely lucid way, he tackles the major objections to this otherworldly revelation until his case is inescapably established. Rarely does a book so fully reorganize how we think about our place in the universe. We are on the threshold of a new understanding—of where we are in the cosmos, and what we are made of.

    Authors Greg Bear (Eon) and Timothy Zahn (The Last Command) provide non-stop, heart-pounding action that will keep readers on edge until the final page.

    This authoritative yet accessible study is the ultimate astronomy lesson. Combining fascinating and often alarming scenarios that seem plucked from science fiction with the latest research and opinions, Plait illustrates why outer space is not as remote as most people think. Each chapter explores a different phenomenon, explaining it in easy-to-understand terms, and considering how life on earth and the planet itself would be affected should the event come to pass. Rather than sensationalizing the information, Plait analyzes the probability of these catastrophes occurring in our lifetimes and what we can do to stop them. With its entertaining tone and enlightening explanation of unfathomable concepts, Death from the Skies! will appeal to science buffs and beginners alike.

    For example, the author analyzes the android Data and asks: Is Data a person? This question launches the reader into a philosophical discussion about ourselves and our knowledge of others. Another topic examined is the transporter, a device that dematerializes objects and rematerializes them in another location. Can someone really survive this process? And how does this experience affect personal identity?

    Nearly a decade after Captain Kirk vanished, his protege, Captain Hiraku Sulu of the USS Excelsior, leads a dangerous mission into uncharted political waters. Unprecedented peace talks with the violently xenophobic Tholian Assembly trigger a deadly confrontation aboard the Excelsior. Now Sulu and his crew - including Chekov, Rand, Chapel, Tuvok, and Akaar - are thrust into an unexpected conflict between the Tholians and a mysterious new enemy, the Neyel... whose origins, if revealed, could lead to war with Earth itself. As the Tholians weave a web of vengeance, the Excelsior is flung beyond the galaxy and the crew discovers the hidden truth about the alien Neyel, forcing Sulu to question where his responsibilities lie - with the fragile peace he must preserve, or with the victims of his own world's tragic past.

    Taking place between the events of Coyote Rising and Coyote Frontier, it follows three individuals -- Marie Montero and Lars Thompson, veterans of the recent revolution against Earth, and Manuel Castro, a posthuman Savant who was once the colony world's lieutenant governor -- as they set on a journey to explore Coyote's uncharted regions."Steele's intimate stand-alone novella of the fronrtier planet of Coyote chronicles the redemptive journey of two colony exiles, adding a brilliant brushstroke to the already vast6 and vivid canvas of the Coyote saga ,,, With a sophistication reminiscent of some of the genre's greatest visionaries, Steele has created a must-read for anyone who enjoys thought-provoking SF..." -- Publisher's Weekly

    If the anthropologists can't help resolve the conflict between the feuding alien factions, no one will survive.This edition features sixteen full-page illustrations by Doug Beekman.

    That was barely the beginning.The swarm—a cloud of meteors and asteroids 50,000 miles across—was coming. Hundred of missiles put Earth under siege, forcing the world in a panicked hell of anarchy and catastrophe. Riots and orgies rampaged in the rubble. And worse waited.Because at the swarm’s heart was Shiva—a 30 billion-ton comet set to hit earth with the force of 250,000 H-bombs. The impact would turn seas into vapor and mountains into dust. Pray, scream, get drunk, or run amok—but no one could escape it. No one could survive it.And no one could stop it.

    Only the priests and priestesses of the ancient martial orders have prevented the utter destruction of their kind. But a newly arisen ruler, the Dark Queen, seeks to destroy the ages-old equilibrium. All that stands before her is a child of prophecy, a child destined to unite their race. A child the Dark Queen must kill at any cost...

    During this brief window, the people of Xondaii undertake a massive interplanetary operation: mineral ore is ferried from the mining operation while supplies, crew replacements, and so on are transported from the planet. Also, communications with the mining colony on the planetoid are possible only when the rift is open.  Science vessel U.S.S. Robert Ballard is severely damaged during its mission to the system, and the U.S.S. Enterprise is dispatched to investigate and render assistance. But Kirk, Spock, and Sulu also collect the data about the rift, and the evidence they’ve gathered regarding its artificial nature is compelling. How has this not been discovered by anyone from Xondaii, especially when considering the extensive mining operations that have been in place for decades? And what can prevent enemies of the Federation from exploiting this newfound power?

    Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.
