The inside story of the new race to conquer space, as Elon Musk and Jeff Bezos spend billions of their own money to explore the final frontier For the larger-than-life personalities now staking their fortunes on the development of rocket ships, the new race to explore space could be a dead end, a lucrative opportunity -- or the key to humanity's salvation. Elon Musk and Jeff Bezos take center stage in this fast-paced narrative as they attempt to disrupt the space economy, feed their own egos, and maybe even save the world. We also meet a supporting cast of equally fascinating entrepreneurs, from the irrepressible British mogul Richard Branson to satellite Internet visionary Greg Wyler. All are united in the profound conviction that commercial space transportation will transform our world for the better. Tim Fernholz's fly-on-the-wall reporting captures an industry in the midst of disruption, as NASA seeks to preserve its ambitious space exploration program, traditional aerospace firms like Boeing and Loc

迷失在过去和现在世界各大城市地下的苣大下水道网络中：让详细的档案计划，地图和照片引导你通过这些地下迷宫-以前只有他们的建设者，工程师，或者古怪的流氓探险家。这种可恨的探索追溯了废物管理的演变，从古代世界精巧的基础设施到中世纪渗水的污水坑和溃烂的露天下水道。它调查并赞扬了土木工程师的工作，他们开创性的综合下水道系统结束了19世纪中期毁灭性的霍乱疫情，并继续为今天大量增加的人口服务。 Lose yourself in the vast sewer networks that lie beneath the world s great cities past and present. Let detailed archival plans, maps and photographs guide you through these subterranean labyrinths previously accessible only to their builders, engineers and, perhaps, the odd rogue explorer. This execrable exploration traces the evolution of waste management from the ingenious infra-structures of the ancient world to the seeping cesspits and f

Heredity is redefined in this sweeping, resonating overview of a force that shaped human society--a force set to shape our future even more radically. "Extraordinary"--New York Times Book Review "Magisterial"--The Atlantic "Engrossing"--Wired "Leading contender as the most outstanding nonfiction work of the year"--Minneapolis Star-Tribune Award-winning, celebrated New York Times columnist and science writer Carl Zimmer presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities... But, Zimmer writes, "
