Eleven Seconds into the Unknown: A History of the Hyper-X Program is a sequel to the author's first book on the X-43A/Hyper-X project, Road to Mach 10: Lessons Learned from the X-43A Flight Research Program. The Hyper-X program involved the efforts of numerous governmental and commercial organizations, each with its own culture, experience, and tradition. A central theme of the Hyper-X story is how these disparate groups and organizations became a unified team working toward a common goal. Making the team's task more difficult were the technological, political, and funding challenges during nearly fifty years of scramjet development. Eleven Seconds into the Unknown: A History of the Hyper-X Program addresses these issues in compelling fashion, and will appeal to anyone interested in high-speed flight, aerospace history, the organization and management of technological projects, and the future of spaceflight.

This is the first full-length test-flight history of the X-43 project, written by the project historian at Dryden Flight Research Center. The project achieved the first in-flight testing of a scramjet engine, at speeds of nearly Mach 7 and Mach 10.

“An engaging voyage into some of the great mysteries and wonders of our world." --Alan Lightman, author of Einstein’s Dream and The Accidental Universe “No one is better at making the recondite accessible and exciting.” —Bill Bryson Brain Pickings and Kirkus Best Science Book of the Year Every week seems to throw up a new discovery, shaking the foundations of what we know. But are there questions we will never be able to answer—mysteries that lie beyond the predictive powers of science? In this captivating exploration of our most tantalizing unknowns, Marcus du Sautoy invites us to consider the problems in cosmology, quantum physics, mathematics, and neuroscience that continue to bedevil scientists and creative thinkers who are at the forefront of their fields. At once exhilarating, mind-bending, and compulsively readable, The Great Unknown challenges us to consider big questions—about the nature of consciousness, what came before the big bang, and what lies beyond our horizons—while taking us on a virtuoso tour of the great breakthroughs of the past and celebrating the men and women who dared to tackle the seemingly impossible and had the imagination to come up with new ways of seeing the world.

A groundbreaking guide to the universe and how our latest deep-space discoveries are forcing us to revisit what we know—and what we don't. On March 21, 2013, the European Space Agency released a map of the afterglow of the Big Bang. Taking in 440 sextillion kilometres of space and 13.8 billion years of time, it is physically impossible to make a better map: we will never see the early universe in more detail. On the one hand, such a view is the apotheosis of modern cosmology, on the other, it threatens to undermine almost everything we hold cosmologically sacrosanct. The map contains anomalies that challenge our understanding of the universe. It will force us to revisit what is known and what is unknown, to construct a new model of our universe. This is the first book to address what will be an epoch-defining scientific paradigm shift. Stuart Clark will ask if Newton's famous laws of gravity need to be rewritten; if dark matter and dark energy are just celestial phantoms? Can we ever know what happened before the Big Bang? What’s at the bottom of a black hole? Are there universes beyond our own? Does time exist? Are the once immutable laws of physics changing?

#1 New York Times #1 Wall Street Journal #1 Los Angeles Times #1 Entertainment Weekly #1 Publishers Weekly Stephanie Plum is thinking her career as a fugitive apprehension agent has run its course. She's been shot at, spat at, cussed at, fire-bombed, mooned, and attacked by dogs. Time for a change, Stephanie thinks. Time to find the kind of job her mother can tell her friends about without making the sign of the cross. So Stephanie Plum quits. Resigns. No looking back. No changing her mind. She wants something safe and normal. As it turns out, jobs that are safe and normal for most people aren't necessarily safe and normal for Stephanie Plum. Trouble follows her, and the kind of trouble she had at the bail bonds office can't compare to the kind of trouble she finds herself facing now. Her past has come back to haunt her. She's stalked by a maniac returned from the grave for the sole purpose of putting her into a burial plot of her own. He's killed before, and he'll kill again if given the chance. Caught between staying far away from the bounty hunter business and staying alive, Stephanie reexamines her life and the possibility that being a bounty hunter is the solution rather than the problem. After disturbingly brief careers at the button factory, Kan Klean Dry Cleaners, and Cluck-in-a-Bucket, Stephanie takes an office position in security, working for Ranger, the sexiest, baddest bounty hunter and businessman on two continents. It might not be the job she'll keep for the rest of her life, but for now it gives her the technical access she needs to find her stalker. Tempers and temperatures rise as competition ratchets up between the two men in her life---her on-again, off-again boyfriend, tough Trenton cop Joe Morelli, and her bad-ass boss, Ranger. Can Stephanie Plum take the heat? Can you? Between the adventure and the adversity there's attitude, and Stephanie Plum's got plenty in her newest misadventure from Janet Evanovich, Eleven on Top.
