Short stories and science writing from a Robert A. Heinlein Award winner: “Allen Steele is among the best.” —St. Louis Post-Dispatch In Rude Astronauts, Allen Steele presents some of his finest stories—including the Diamondback Jack Trilogy and his first published story, “Live from the Mars Hotel”—along with excerpts of the nonfiction science writing with which he made his name. In Steele’s universe, the stars are cold, space is big, and it’s the normal people who make things interesting.

Despite the growing importance of economics in our lives, literary scholars have long been reluctant to consider economic issues as they examine key texts. This volume seeks to fill one of these conspicuous gaps in the critical literature by focusing on various connections between science fiction and economics, with some attention to related fields such as politics and government. Its seventeen contributors include five award-winning scholars, five science fiction writers, and a widely published economist. Three topics are covered: what noted science fiction writers like Robert A. Heinlein, Frank Herbert, and Kim Stanley Robinson have had to say about our economic and political future; how the competitive and ever-changing publishing marketplace has affected the growth and development of science fiction from the nineteenth century to today; and how the scholars who examine science fiction have themselves been influenced by the economics of academia. Although the essays focus primarily on American science fiction, the traditions of Russian and Chinese science fiction are also examined. A comprehensive bibliography of works related to science fiction and economics will assist other readers and critics who are interested in this subject.

A collection of stories and poems by members of the Libertarian Futurist Society, a movement which thinks that space will liberate man. He will be "happier, healthier and smarter, " says the editor in the introduction. A group of writers including Poul Anderson, John Barnes, Gregory Benford, Ray Bradbury, and others offers stories about the twenty-third century, where individual societies outside of Earth have evolved into a galactic federation without formalized government known as Free Space.

Another dazzling collection of fact, fiction, and wit from the Hugo and Nebula Award-winning master of hard science fiction! Larry Niven is the New York Times bestselling author of such classic science fiction novels as Ringworld and Destiny's Road. His previous collection, N-Space, was lauded by the Houston Post as "outstanding . . . hours of entertainment," while Publishers Weekly called it "a must for science fiction fans." A follow-up volume, Playgrounds of the Mind, was similarly praised by Kirkus Reviews: "An abundance of Niven's curious yet disciplined inventiveness and his fun-filled knack for turning seemingly absurd notions into credible, absorbing fiction. Grand entertainment." Now, ten years later, Scatterbrain collects an equally engaging assortment of Niven's latest work, all in one captivating volume. Here are choice excerpts from several of his most recent novels, including his upcoming Ringworld's Child and Rainbow Mars, as well as numerous short stories, nonfiction articles, interviews, editorials, collaborations, and correspondence. True to its title, Scatterbrain roams all over a wide variety of fascinating topics, featuring Niven's singular insights into everything from space stations to convention etiquette. So give yourself a treat, and feel free to pick the brain-or Scatterbrain-of one of modern science fiction's most fascinating thinkers.

"A cautionary tale with a disturbing resemblance to past history and future possibilities" (Milton Friedman, Nobel Laureate), "Alongside Night" portrays the last two weeks of the world's greatest superpower and ends on a triumphant note of hope.

In the parallel world first introduced in S. M. Stirling's The Sky People, aliens terraformed Mars (and Venus) two hundred million years ago, seeding them with life-forms from Earth. In the Courts of the Crimson Kings is set in that same astonishing world. Humans didn't suspect this until the twentieth century, but when the first probes landed on our sister worlds, and found life—intelligent life, at that—things changed with a vengeance. By the year 2000, America, Russia, and the other great powers of Earth are all contending for influence and power amid the newly-discovered inhabitants of our sister planets. Venus is a primitive world. But on Mars, early hominids evolved civilization earlier than their earthly cousins, driven by the needs of a harsh world growing still harsher as the initial terraforming runs down. Without coal, oil, or uranium, their technology was forced into different paths, and the genetic wizardry of the Crimson Dynasty united a world for more than twenty thousand years. Now, in a new stand-alone adventure set in this world's 2000 AD, Jeremy Wainman is an archaeologist who has achieved a lifelong dream; to travel to Mars and explore the dead cities of the Deep Beyond, searching for the secrets of the Kings Beneath the Mountain and the fallen empire they ruled. Teyud Zha-Zhalt is the Martian mercenary the Terrans hire as guide and captain of the landship Intrepid Traveller. A secret links her to the deadly intrigues of Dvor il-Adazar, the City That Is A Mountain, where the last aging descendant of the Tollamune Emperors clings to the remnants of his power...and secrets that may trace their origin to the enigmatic Ancients, the Lords of Creation who reshaped the Solar System in the time of the dinosaurs. When these three meet, the foundations of reality will be shaken—from the lost city of Rema-Dza to the courts of the Crimson Kings.

What Is Pulse Detonation Engine A pulse detonation engine (PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next. Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of roughly Mach 5. An ideal PDE design can have a thermodynamic efficiency higher than other designs like turbojets and turbofans because a detonation wave rapidly compresses the mixture and adds heat at constant volume. Consequently, moving parts like compressor spools are not necessarily required in the engine, which could significantly reduce overall weight and cost. PDEs have been considered for propulsion since 1940. Key issues for further development include fast and efficient mixing of the fuel and oxidizer, the prevention of autoignition, and integration with an inlet and nozzle. To date, no practical PDE has been put into production, but several testbed engines have been built and one was successfully integrated into a low-speed demonstration aircraft that flew in sustained PDE powered flight in 2008. In June 2008, the Defense Advanced Research Projects Agency (DARPA) unveiled Blackswift, which was intended to use this technology to reach speeds of up to Mach 6 How You Will Benefit (I) Insights, and validations about the following topics: Chapter 1: Pulse Detonation Engine Chapter 2: Nuclear Pulse Propulsion Chapter 3: Rotating Detonation Engine Chapter 4: AIMStar Chapter 5: Antimatter-catalyzed nuclear pulse propulsion Chapter 6: Antimatter rocket Chapter 7: Nuclear electric rocket Chapter 8: Nuclear power in space Chapter 9: Nuclear propulsion Chapter 10: Nuclear thermal rocket Chapter 11: Project Pluto Chapter 12: Fission-fragment rocket (II) Answering the public top questions about pulse detonation engine.

Told in a chorus of voices that spans a generation, "Kings of the Earth" examines the bonds of family and blood, faith and suspicion, that link not just three brothers but their entire community.

When a famous Federation scientist dies, his son puts his inventions up for sale to the highest bidder, be they Federation, Klingon, Romulan, or Cardassian. Among the items at auction is a photon pulse canon capable of punching through a starship's shields with a single shot. Meanwhile, Wesley Crusher is kidnapped from the Academy by renegade Ferengi who have set their sights on the photon canon as well, and Captain Picard must outmaneuver enemies on every side to save Wesley and protect the EnterpriseTM from the deadly fire of the new canon.
