A favorite of Tesla and SpaceX founder Elon Musk, listeners will want to tune into this "really good book on rocket[s]," available for the first time in audio. Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, listeners will want to get their hands on this influential classic, available for the first time in decades.

    We nevertheless muddle through even in the absence of theories of how to act. But how do we do it?In Probably Approximately Correct, computer scientist Leslie Valiant presents a masterful synthesis of learning and evolution to show how both individually and collectively we not only survive, but prosper in a world as complex as our own. The key is “probably approximately correct” algorithms, a concept Valiant developed to explain how effective behavior can be learned. The model shows that pragmatically coping with a problem can provide a satisfactory solution in the absence of any theory of the problem. After all, finding a mate does not require a theory of mating. Valiant’s theory reveals the shared computational nature of evolution and learning, and sheds light on perennial questions such as nature versus nurture and the limits of artificial intelligence.Offering a powerful and elegant model that encompasses life’s complexity, Probably Approximately Correct has profound implications for how we think about behavior, cognition, biological evolution, and the possibilities and limits of human and machine intelligence.

    Desperate, she decides to take a chance and ask her favourite writer, a celebrated but reclusive English novelist, to help her find a second chance. When she receives the author's reply in an envelope with a Cornish postmark, Maisie decides not to take the writer's half-hearted 'no' for an answer. With nothing to lose, she takes off for the author's last known location, a beautiful hotel on Cornwall's western coast. But when the hotel mistakes her for the latest applicant for a maid's position, Maisie finds herself given an opportunity too good to lose ... and a chance for a summer adventure far bigger than she ever imagined. Surrounded by breathtaking Cornwall and working in an elegant hotel, Maisie's world becomes one of secret identities, quirky friends, and unintentional mishaps — and despite reminders of past relationship disasters, a certain handsome, charming local resident Sidney Daniels has her conflicted about her heart's desires, too. Will Maisie find the chance she's been waiting for — and a possible new romance — in her perfect Cornish summer?

    The author writes, "[t]his is not a swing instruction book. You are not going to find the latest 'secrets' of golf, it is not going to tell you the 'one magical key' in your backswing, and it is not going to replace your teacher or golf coach. This book deals with something far more important than what to learn; it deals with HOW to learn, and how to transfer that learning to the course."

    All new stories set in the Ring of Fire series, edited by New York Times best-selling series creator Eric Flint.Europe, 1632. It is a time of upheaval and great change. But none so great as when an unexplained temporal and spatial phenomenon known as the Ring of Fire transports the blue collar town of Grantville, West Virginia, smack dab in the middle of the Thirty Years War. When the dust settles, it becomes clear that the town of Grantville isn't going anywhere, and the can-do Americans of the twenty-first century begin altering the course of history forever. It is now five years later, and the effects of the Ring of Fire reach from the Old World to the New. But the course of exploration and colonization will look much different than it did in our timeline. The French bought the English possessions in North America way back in 1633, but have never done much with the uncivilized backwater. Until the new king of France, Gaston I, decides that it's time to seize the territory and establish French control over it. Here then, a new anthology, edited by Ring of Fire series creator Eric Flint, chronicling the exploits of the citizens of Grantville, their allies, and their enemies, as they venture forth onto a new continent.

    It's like thinking the unthinkable. After all, the farm population is dwindling. It takes too much capital to start. The pay is too low. The working conditions are dusty, smelly and noisy: not the place to raise a family. This is all true, and more, for most farmers. But for farm entrepreneurs, the opportunities for a farm family business have never been greater. The aging farm population is creating cavernous niches begging to be filled by creative visionaries who will go in dynamic new directions. As the industrial agriculture complex crumbles and our culture clambers for clean food, the countryside beckons anew with profitable farming opportunities. While this book can be helpful to all farmers, it targets the wannabes, the folks who actually entertain notions of living, loving and learning on a piece of land. Anyone willing to dance with such a dream should be able to assess its assets and liabilities; its fantasies and realities. "Is it really possible for me?" is the burning question this book addresses.

    It would become the world's most baffling mathematical mystery. Simple, elegant, and utterly impossible to prove, Fermat's Last Theorem captured the imaginations of amateur and professional mathematicians for over three centuries. For some it became a wonderful passion. For others it was an obsession that led to deceit, intrigue, or insanity. In a volume filled with the clues, red herrings, and suspense of a mystery novel, Dr. Amir Aczel reveals the previously untold story of the people, the history, and the cultures that lie behind this scientific triumph. From formulas devised for the farmers of ancient Babylonia to the dramatic proof of Fermat's theorem in 1993, this extraordinary work takes us along on an exhilarating intellectual treasure hunt. Revealing the hidden mathematical order of the natural world in everything from stars to sunflowers, "Fermat's Last Theorem" brilliantly combines philosophy and hard science with investigative journalism. The result: a real-life detective story of the intellect, at once intriguing, thought-provoking, and impossible to put down.
