Book Description
Nowhere in the world is weather as volatile and powerful as it is in North America. Scorching heat in the Southwest, hurricanes on the Atlantic coast, tornadoes in the Plains, blizzards in the mountains: Every area of the country has vastly different weather, and vastly different cultures as a result. Braving the Elements is David Laskin's delightful and fascinating history of how our unique weather has shaped a nation, and how we've tried to cope with it over centuries. Since before Columbus, the peoples of America have struggled to make sense of the capricious and violent nature of America's weather. Anasazi Indians used the rain dance (and sometimes human sacrifice) to induce rain, while the Puritans in New England blamed the sins of the community for lightening strikes and Nor'easters. IN modern times we carry on those traditions by blaming the weatherman for ruined weekends. Despite hi-tech satellites and powerful computers and 24-hour-a-day forecasting from The Weather Channel, we're still at the mercy of the whims of Mother Nature. Laskin recounts the many dramatic moments in American weather history, from the "Little Ice Age" to Ben Franklin's invention of the lightning rod to the Great Blizzard of the 1930's to the worries about global warming. Packed with fresh insights and wonderful lore and trivia, Braving the Elements is unique and essential reading for anyone who's ever asked, "What's it like outside?"

Book Description
First published in 1956, this is an account of the arming of the Union forces in the Civil War, and of Lincoln’s part in it. It has never been told in any comprehensive way before, and shows Lincoln in a new and engaging light. Lincoln was determined to win the war, yet his generals seemed unable to give him a victory, so he reasoned that a more efficient weapon would have to be invented. However, his main opponent, General James W. Ripley, who sat in charge of army ordnance, believed the war would be short and didn’t want a vast supply of expensive arms left over. Standardized guns and ammunition made supplying the troops in the field easier. Lincoln was in the thick of it. He wanted mortar boats to help open the upper Mississippi as they had helped Porter take New Orleans. When he discovered a big snafu had delayed production, one J. D. Mills came to Washington with a crude machine gun that was soon christened the coffee-mill gun. Probably the biggest and longest controversy involved muzzle-loading rifles—favoured by Ripley—and breech-loading rifles—the Soldier’s choice, as he could lie down and load a breechloader at least five times as fast as a muzzle-loader. In addition to these and other standard arms, the inventors offered a wide catalogue of innovations: rockets, steam guns, liquid fire, a submarine, explosive bullets, a proposed poison gas, and so on down to the fantastic. This book is a big American story of Washington in wartime, and it will appeal to everybody who ever had any contact with the armed services. For the specialist, it offers quite a quantity of previously unpublished material. Its biggest merit is, however, that it is just plain fascinating reading, the kind of book no one should start late in the evening if he wants any sleep.

Book Description
The classic case for why government must support science—with a new essay by physicist and former congressman Rush Holt on what democracy needs from science today Science, the Endless Frontier is recognized as the landmark argument for the essential role of science in society and government’s responsibility to support scientific endeavors. First issued when Vannevar Bush was the director of the US Office of Scientific Research and Development during the Second World War, this classic remains vital in making the case that scientific progress is necessary to a nation’s health, security, and prosperity. Bush’s vision set the course for US science policy for more than half a century, building the world’s most productive scientific enterprise. Today, amid a changing funding landscape and challenges to science’s very credibility, Science, the Endless Frontier resonates as a powerful reminder that scientific progress and public well-being alike depend on the successful symbiosis between science and government. This timely new edition presents this iconic text alongside a new companion essay from scientist and former congressman Rush Holt, who offers a brief introduction and consideration of what society needs most from science now. Reflecting on the report’s legacy and relevance along with its limitations, Holt contends that the public’s ability to cope with today’s issues—such as public health, the changing climate and environment, and challenging technologies in modern society—requires a more capacious understanding of what science can contribute. Holt considers how scientists should think of their obligation to society and what the public should demand from science, and he calls for a renewed understanding of science’s value for democracy and society at large. A touchstone for concerned citizens, scientists, and policymakers, Science, the Endless Frontier endures as a passionate articulation of the power and potential of science.
