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.

    It is iconoclastic, crosses disciplinary boundaries, and finally it is calm and compellingly reasonable. The book was widely read on both sides of the Iron Curtain and the result was serious revision in both Western and Soviet strategy and doctrine. As a result, both sides were better able to avoid disaster during the Cold War.The strategic concepts still apply: defense, local animosities, and the usual balance-of-power issues are still very much with us. Kahn's stated purpose in writing this book was simply: "avoiding disaster and buying time, without specifying the use of this time." By the late 1950s, with both sides H-bomb-armed, reason and time were in short supply.Kahn, a military analyst at Rand since 1948, understood that a defense based only on thermonuclear arnaments was inconceivable, morally questionable, and not credible.The book was the first to make sense of nuclear weapons. Originally created from a series of lectures, it provides insight into how policymakers consider such issues. One may agree with Kahn or disagree with him on specific issues, but he clearly defined the terrain of the argument. He also looks at other weapons of mass destruction such as biological and chemical, and the history of their use.The Cold War is over, but the nuclear genie is out of the bottle, and the lessons and principles developed in On Thermonuclear War apply as much to today's China, Russia, Iran, and North Korea as they did to the Soviets.

    Innovator. Inventor. These three words sum up Alexander Graham Bell, one of the greatest scientific men of his era. He is most famous for the invention of the telephone, a device which he predicted would transform human society. And it did. But the telephone is just one of the many innovations and inventions that Bell brought into being. Inside you will read about... - Childhood - Emigration to North America - The Bell Telephone Company - The Race to Save the President - A Rival to the Wright Brothers - Later Years and Death And much more! A man who epitomizes the word visionary, Alexander Graham Bell predicted the use of light as a medium for transmitting information and how humanity would be transformed by flight. This is his story.

    In these pages the virtuoso scientists who plumbed the secrets of electricity come vividly to life, including familiar giants like Thomas Edison; the visionary Michael Faraday, who struggled against the prejudices of the British class system; and Samuel Morse, a painter who, before inventing the telegraph, ran for mayor of New York on a platform of persecuting Catholics. Here too is Alan Turing, whose dream of a marvelous thinking machine—what we know as the computer—was met with indifference, and who ended his life in despair after British authorities forced him to undergo experimental treatments to “cure” his homosexuality. From the frigid waters of the Atlantic to the streets of Hamburg during a World War II firestorm to the interior of the human body, Electric Universe is a mesmerizing journey of discovery by a master science writer.

    Yuri Gagarin is one of the great heroes of the twentieth century, but the details of his life and the Russian space effort have been shrouded in secrecy: even the names of the engineers who worked with Gagarin were a mystery to the West for many years.Starman is the first book to tell the compelling story behind Gagarin's life and his audacious first flight into space aboard a converted nuclear weapon.He was once the most famous man in the world yet in his life, as in death, he was a man the world knew almost nothing about.

    A member of the first astronaut class to include women, she broke through a quarter-century of white male fighter jocks when NASA chose her for the seventh shuttle mission, cracking the celestial ceiling and inspiring several generations of women.After a second flight, Ride served on the panels investigating the Challenger explosion and the Columbia disintegration that killed all aboard. In both instances she faulted NASA's rush to meet mission deadlines and its organizational failures. She cofounded a company promoting science and education for children, especially girls.Sherr also writes about Ride's scrupulously guarded personal life-she kept her sexual orientation private-with exclusive access to Ride's partner, her former husband, her family, and countless friends and colleagues. Sherr draws from Ride's diaries, files, and letters. This is a rich biography of a fascinating woman whose life intersected with revolutionary social and scientific changes in America. Sherr's revealing portrait is warm and admiring but unsparing. It makes this extraordinarily talented and bold woman, an inspiration to millions, come alive.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Yet in The Science of Interstellar, Kip Thorne, the physicist who assisted Nolan on the scientific aspects of Interstellar, shows us that the movie’s jaw-dropping events and stunning, never-before-attempted visuals are grounded in real science. Thorne shares his experiences working as the science adviser on the film and then moves on to the science itself. In chapters on wormholes, black holes, interstellar travel, and much more, Thorne’s scientific insights—many of them triggered during the actual scripting and shooting of Interstellar—describe the physical laws that govern our universe and the truly astounding phenomena that those laws make possible.Interstellar and all related characters and elements are trademarks of and © Warner Bros.

    A groundbreaking account of accidents, near misses, extraordinary heroism, and technological breakthroughs, Command and Control explores the dilemma that has existed since the dawn of the nuclear age: How do you deploy weapons of mass destruction without being destroyed by them? That question has never been resolved—and Schlosser reveals how the combination of human fallibility and technological complexity still poses a grave risk to mankind. While the harms of global warming increasingly dominate the news, the equally dangerous yet more immediate threat of nuclear weapons has been largely forgotten.Written with the vibrancy of a first-rate thriller, Command and Control interweaves the minute-by-minute story of an accident at a nuclear missile silo in rural Arkansas with a historical narrative that spans more than fifty years. It depicts the urgent effort by American scientists, policy makers, and military officers to ensure that nuclear weapons can’t be stolen, sabotaged, used without permission, or detonated inadvertently. Schlosser also looks at the Cold War from a new perspective, offering history from the ground up, telling the stories of bomber pilots, missile commanders, maintenance crews, and other ordinary servicemen who risked their lives to avert a nuclear holocaust. At the heart of the book lies the struggle, amid the rolling hills and small farms of Damascus, Arkansas, to prevent the explosion of a ballistic missile carrying the most powerful nuclear warhead ever built by the United States.Drawing on recently declassified documents and interviews with people who designed and routinely handled nuclear weapons, Command and Control takes readers into a terrifying but fascinating world that, until now, has been largely hidden from view. Through the details of a single accident, Schlosser illustrates how an unlikely event can become unavoidable, how small risks can have terrible consequences, and how the most brilliant minds in the nation can only provide us with an illusion of control. Audacious, gripping, and unforgettable, Command and Control is a tour de force of investigative journalism, an eye-opening look at the dangers of America’s nuclear age.

    Within that story is the incredible tale of the human conflict between Robert Oppenheimer, Ernest Lawrence, and Edward Teller-the scientists most responsible for the advent of weapons of mass destruction.How did science-and its practitioners-enlisted in the service of the state during the Second World War, become a slave to its patron during the Cold War? The story of these three men, builders of the bombs, is fundamentally about loyalty-to country, to science, and to each other-and about the wrenching choices that had to be made when these allegiances came into conflict.Gregg Herken gives us the behind-the-scenes account based upon a decade of research, interviews, and newly released Freedom of Information Act and Russian documents. Brotherhood of the Bomb is a vital slice of American history told authoritatively-and grippingly-for the first time.

    As obvious as the Presidential motorcade, most people assume the squadron is a travel perk for VIPs. They’re only half right: while the helicopters do provide transport, the unit exists to evacuate high-ranking officials in the event of a terrorist or nuclear attack on the capital. In the event of an attack, select officials would be whisked by helicopters to a ring of secret bunkers around Washington, even as ordinary citizens were left to fend for themselves.For sixty years, the US government has been developing secret Doomsday plans to protect itself, and the multibillion-dollar Continuity of Government (COG) program takes numerous forms—from its plans to evacuate the Liberty Bell from Philadelphia to the plans to launch nuclear missiles from a Boeing-747 jet flying high over Nebraska. In Raven Rock, Garrett M. Graff sheds light on the inner workings of the 650-acre compound (called Raven Rock) just miles from Camp David, as well as dozens of other bunkers the government built its top leaders during the Cold War, from the White House lawn to Cheyenne Mountain in Colorado to Palm Beach, Florida, and the secret plans that would have kicked in after a Cold War nuclear attack to round up foreigners and dissidents and nationalize industries. Equal parts a presidential, military, and cultural history, Raven Rock tracks the evolution of the government plan and the threats of global war from the dawn of the nuclear era through the War on Terror.

    Combining gripping narrative history with wide-ranging analysis, Boot focuses on four “revolutions” in military affairs and describes key battles from each period to explain how inventions ranging from gunpowder to GPS-guided air-strikes have remade the field of battle— and shaped the rise and fall of empires. Bringing to life battles from the defeat of the Spanish Armada to Wellington’s victory at Assaye, War Made New analyzes the Gunpowder Revolution and explains warfare’s evolution from ritualistic, drawn-out engagements to much deadlier events, precipitating the rise of the modern nation state. He next explores the triumph of steel and steam during the Industrial Revolution, including the British triumph at Omdurman and the climax of the Russo-Japanese war at Tsushima, showing how it powered the spread of European colonial empires. Moving into the twentieth century and the Second Industrial Revolution, Boot examines three critical clashes of World War II—the German army’s blitzkrieg, Pearl Harbor, and the firebombing of Tokyo—to illustrate how new technology such as the tank, radio, and airplane ushered in terrifying new forms of warfare that aided the rise of highly centralized, and even totalitarian, world powers. Finally, in his section on the Information Revolution, Boot focuses on the Gulf War, the invasion of Afghanistan, and the Iraq war, arguing that even as cutting-edge technologies such as stealth aircraft have made America the greatest military power in world history, advanced communications systems have allowed decentralized, “irregular” forces to become an increasingly significant threat to Western power. BACKCOVER: Advance Praise for War Made New “Max Boot traces the impact of military revolutions on the course of politics and history over the past 500 years. In doing so, he shows that changes in military technology are limited not to warfighting alone, but play a decisive role in shaping our world. Sweeping and erudite, while entirely accessible to the lay reader, this work is key for anyone interested in where military revolutions have taken us—and where they might lead in the future.” —U.S. Senator John McCain “While much has been in written in recent years about the so-called ‘Revolution in Military Affairs,’ Max Boot is the first scholar to place it within the broad sweep of history, and in the context of the rise of the West in world affairs since 1500. In so doing, he not only tells a remarkable tale, but he compels us all, even those obsessed solely with contemporary military affairs, to ask the right questions and to distinguish what is truly new and revolutionary from what is merely ephemeral. He has rendered a valuable service, and given us a fascinating read at the same time, so we are doubly in his debt.” —Paul Kennedy, Professor of History at Yale University and author of The Rise and Fall of the Great Powers “War Made New is impressive in scope. What is equally impressive is its unique interpretation of the causal relationship between technology, warfare and the contemporary social milieu. This is a superb thinking person's book which scrutinizes conventional historical wisdom through a new lens.” —Lt. Gen. Bernard E. Trainor, USMC (ret.), co-author of Cobra II: The Inside Story of the Invasion and Occupation of Iraq “Max Boot's book takes hundred of years of tactical battle history and reduces it to an incisive narrative of how war has changed. By providing such a coherent view of the past, he has pointed us toward the future. What is doubly impressive is how he draws surprising, fresh lessons from wars we thought we knew so much about but in fact didn't.” —Robert D. Kaplan, author of Imperial Grunts

    Beginning with the publication of Albert Einstein's theory of relativity, through the wild revolution of quantum mechanics, and up until the physics of the modern day (including the astonishing revelation, in 1998, that the Universe is not only expanding, but doing so at an ever-quickening pace), much of what physicists have seen in our Universe suggests that much of our Universe is unseen—that we live in a dark cosmos.Everyone knows that there are things no one can see—the air you're breathing, for example, or, to be more exotic, a black hole. But what everyone does not know is that what we can see—a book, a cat, or our planet—makes up only 5 percent of the Universe. The rest—fully 95 percent—is totally invisible to us; its presence discernible only by the weak effects it has on visible matter around it.This invisible stuff comes in two varieties—dark matter and dark energy. One holds the Universe together, while the other tears it apart. What these forces really are has been a mystery for as long as anyone has suspected they were there, but the latest discoveries of experimental physics have brought us closer to that knowledge. Particle physicist Dan Hooper takes his readers, with wit, grace, and a keen knack for explaining the toughest ideas science has to offer, on a quest few would have ever expected: to discover what makes up our dark cosmos.

    Augustine equate nothingness with the Devil? What tortuous means did 17th-century scientists employ in their attempts to create a vacuum? And why do contemporary quantum physicists believe that the void is actually seething with subatomic activity? You’ll find the answers in this dizzyingly erudite and elegantly explained book by the English cosmologist John D. Barrow.Ranging through mathematics, theology, philosophy, literature, particle physics, and cosmology, The Book of Nothing explores the enduring hold that vacuity has exercised on the human imagination. Combining high-wire speculation with a wealth of reference that takes in Freddy Mercury and Shakespeare alongside Isaac Newton, Albert Einstein, and Stephen Hawking, the result is a fascinating excursion to the vanishing point of our knowledge.
