Sometimes a battle, such as the one that raged along France's Marne River in 1918, involves hundreds of thousands of soldiers and costs many lives. Sometimes, as in the case of Tippecanoe, a battle involves only a few hundred fighters. Great or small, as historian Paul Davis notes, history has turned on clashes such as these. In this well-researched compendium, Davis examines battles that have had far-reaching historical consequences. The first entry covers the Battle of Megiddo, which delivered unto the Egyptian pharaoh Thutmose III an uneasy dominion over Palestine and broadened his empire into Asia; the final entry, set not far from the first, describes the Allied victory over Iraq in Desert Storm, which "denied control of a large portion of the Middle East oil reserves to dictator Saddam Hussein and showed the ability of a multinational coalition to succeed in the post-Cold War world, perhaps setting an example of future international military action." In between Davis considers similarly fateful but often forgotten contests, such as the Battle of Chalons, when another coalition--this one of Visigoths, Romans, and Gallic and Germanic tribes--turned back the huge Mongol army of Attila in A.D. 451, and the Battle of Shanhaikuan, when, in the spring of 1644, China's Ming dynasty fell to Manchu invaders. Davis sometimes prefers sweeping themes to mundane realities (the fact, for instance, that the Battle of Adrianople turned on the recent invention of the stirrup), and his compendium tends heavily toward Europe at the expense of other parts of the world. The illustrations are also of uneven quality and usefulness. Still, readers with an interest in military history will find this to be a handy reference and overview, and they'll enjoy second-guessing the author, nominating battles that didn't make his hundred while learning from the obscure, but nonetheless critical, ones that he does address. --Gregory McNamee

Maybe we have a future after all: Our Posthuman Future is political historian Francis Fukuyama's reconsideration of his 1989 announcement that history had reached an end. He claims that science, particularly genome studies, offers radical changes, possibly more profound than anything since the development of language, in the way we think about human nature. He makes his case thoroughly and eloquently, rarely dipping into philosophical or critical jargon and consistently maintaining an informal tone.Fukuyama is deeply concerned about the erosion of the foundations of liberal democracy under pressure from new concepts of humans and human rights, and most readers will find some room for agreement. Ultimately, he argues for strong international regulation of human biotechnology and thoughtfully disposes of the most compelling counterarguments. While readers might not agree that we're at risk of creating Huxley's Brave New World, it's hard to deny that things are changing quickly and that perhaps we ought to consider the changes before they're irrevocable. --Rob Lightner

So much of what is commonplace today was once considered impossible, or at least wishful thinking. Laser beams in the operating room, cars with built-in guidance systems, cell phones with email access. There's just no getting around the fact that technology always has, and always will be, very cool.But technology isn't only cool; it's also very smart. That's why one of the hottest technological trends nowadays is the creation of smart homes.At an increasing rate, people are turning their homes into state-of-the-art machines, complete with more switches, sensors, and actuators than you can shake a stick at. Whether you want to equip your home with motion detectors for added security, install computer-controlled lights for optimum convenience, or even mount an in-home web cam or two purely for entertainment, the world is now your oyster. Ah, but like anything highly technical, creating a smart home is typically easier said than done.Thankfully, Smart Home Hacks takes the guesswork out of the process. Through a seemingly unending array of valuable tips, tools, and techniques, Smart Home Hacks explains in clear detail how to use Mac, Windows, or Linux to achieve the automated home of your dreams.

Few lives of great men offer so much interest--and so many mysteries--as the life of Charles Darwin, the greatest figure of nineteenth-century science, whose ideas are still inspiring discoveries and controversies more than a hundred years after his death. Yet only now, with the publication of Voyaging, the first of two volumes that will constitute the definitive biography, do we have a truly vivid and comprehensive picture of Darwin as man and as scientist. Drawing upon much new material, supported by an unmatched acquaintance with both the intellectual setting and the voluminous sources, Janet Browne has at last been able to unravel the central enigma of Darwin's career: how did this amiable young gentleman, born into a prosperous provincial English family, grow into a thinker capable of challenging the most basic principles of religion and science? The dramatic story of Voyaging takes us from agonizing personal challenges to the exhilaration of discovery; we see a young, inquisitive Darwin gradually mature, shaping, refining, and finally setting forth the ideas that would at last fall upon the world like a thunderclap in The Origin of Species.
