Marcelo Gleiser explores the shared quest of ancient prophets and today's astronomers to explain the strange phenomena of our skies--from the apocalypse foretold in Revelations to modern science's ongoing identification of multiple cataclysmic threats, including the impact of comets and asteroids on earthly life, the likelihood of future collisions, the meaning of solar eclipses and the death of stars, the implications of black holes for time travel, and the ultimate fate of the universe and time. Presenting insights to cosmological science and apocalyptic philosophy in an "easily accessible" (Library Journal) style, Gleiser is "a rare astrophysicist as comfortable quoting Scripture as explaining formulas" (Booklist). K. C. Cole praises his ability to "[work] the entwined threads of science and religion into a vision of the end' that is strangely comforting and inspiring.

    With a hundred dollars in his pocket, a beat up cavalry saddle, and a faraway look in his eye, John Egenes saddled his horse Gizmo and started down the trail on an adventure across the North American continent. Their seven month journey took them across 11 states from California to Virginia, ocean to ocean.. As they left the pressing confinement of the city behind them, the pair experienced the isolation and loneliness of the southwestern deserts, the vastness of the prairie, and the great landscapes that make up America. Across hundreds of miles of empty land they slept with coyotes and wild horses under the stars, and in urban areas they camped alone in graveyards and abandoned shacks. Along the way John and Gizmo were transformed from inexperienced horse and rider to veterans of the trail. With his young horse as his spiritual guide John slowly began to comprehend his own place in the world and to find peace within himself. Full of heart and humor, Egenes serves up a tale that's as big as the America he witnessed, an America that no longer exists. It was a journey that could only have been experienced step by step, mile by mile, from the view between a horse's ears.

    Smil argues that no advanced economy can prosper without a strong, innovative manufacturing sector and the jobs it creates.Smil explains how manufacturing became a fundamental force behind America's economic, strategic, and social dominance. He describes American manufacturing's rapid rise at the end of the nineteenth century, its consolidation and modernization between the two world wars, its role as an enabler of mass consumption after 1945, and its recent decline. Some economists argue that shipping low-value jobs overseas matters little because the high-value work remains in the United States. But, asks Smil, do we want a society that consists of a small population of workers doing high-value-added work and masses of unemployed?Smil assesses various suggestions for solving America's manufacturing crisis, including lowering corporate tax rates, promoting research and development, and improving public education. Will America act to preserve and reinvigorate its manufacturing? It is crucial to our social and economic well-being; but, Smil warns, the odds are no better than even.

    --Carlo Rovelli, author of Seven Brief Lessons on Physics and Helgoland You've got questions: about space, time, gravity, and the odds of meeting your older self inside a wormhole. All the answers you need are right here.As a species, we may not agree on much, but one thing brings us all together: a need to know. We all wonder, and deep down we all have the same big questions. Why can't I travel back in time? Where did the universe come from? What's inside a black hole? Can I rearrange the particles in my cat and turn it into a dog?Researcher-turned-cartoonist Jorge Cham and physics professor Daniel Whiteson are experts at explaining science in ways we can all understand, in their books and on their popular podcast, Daniel and Jorge Explain the Universe. With their signature blend of humor and oh-now-I-get-it clarity, Jorge and Daniel offer short, accessible, and lighthearted answers to some of the most common, most outrageous, and most profound questions about the universe they've received.This witty, entertaining, and fully illustrated book is an essential troubleshooting guide for the perplexing aspects of reality, big and small, from the invisible particles that make up your body to the identical version of you currently reading this exact sentence in the corner of some other galaxy. If the universe came with an FAQ, this would be it.

    Whether it is Hannibal of Carthage marching elephants across the Alps and attacking the heart of Rome, Khalid ibn al-Walid boasting an undefeated military career and destroying the Persian Empire while subduing the Byzantines, or Russian General Alexander Suvurov and his elevation of the bayonet to a work of art that could cut down any European army, great military leaders have exerted tremendous influence on society. This book will look at the lives of the ten greatest military commanders in history. Some conquered the fullest expanse of the known world, as did Alexander the Great. Still others were master statesmen and capable of translating military victory into long-term political gains, such as Julius Caesar, whose vanquishing of the Gauls and his political opponents laid the groundwork for several centuries of unmatchable Roman imperial might. It will also look at the tactics they used to bring down stronger armies and befuddle them at every turn; whether it is Napoleon, who nearly conquered Europe through his deadly manoeuvre sur les derrieres and marching unexpectedly away from the enemy's main strength and concentrating on a weak but vital enemy point; or Hannibal's double entrapment maneuver, which has been the envy of military strategists for the last 2,000 years. Whatever their background, these rulers show that the right military commander at the right time in history can destroy an empire, change civilization, and alter the course of world history forever.
