    It imagines passing clouds to be permanent and is blind to powerful, long-term shifts taking place in full view of the world.” —George Friedman In his long-awaited and provocative new book, George Friedman turns his eye on the future—offering a lucid, highly readable forecast of the changes we can expect around the world during the twenty-first century. He explains where and why future wars will erupt (and how they will be fought), which nations will gain and lose economic and political power, and how new technologies and cultural trends will alter the way we live in the new century.The Next 100 Years draws on a fascinating exploration of history and geopolitical patterns dating back hundreds of years. Friedman shows that we are now, for the first time in half a millennium, at the dawn of a new era—with changes in store, including:• The U.S.-Jihadist war will conclude—replaced by a second full-blown cold war with Russia.• China will undergo a major extended internal crisis, and Mexico will emerge as an important world power.• A new global war will unfold toward the middle of the century between the United States and an unexpected coalition from Eastern Europe, Eurasia, and the Far East; but armies will be much smaller and wars will be less deadly.• Technology will focus on space—both for major military uses and for a dramatic new energy resource that will have radical environmental implications.• The United States will experience a Golden Age in the second half of the century.Written with the keen insight and thoughtful analysis that has made George Friedman a renowned expert in geopolitics and forecasting, The Next 100 Years presents a fascinating picture of what lies ahead.For continual, updated analysis and supplemental material, go to www.Stratfor.com

    In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving.Helgoland is a treeless island in the North Sea where the twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious.As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness.Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it.

    In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires. At the heart of the story are Thomas Alva Edison, the nation’s most famous and folksy inventor, creator of the incandescent light bulb and mastermind of the world’s first direct current electrical light networks; the Serbian wizard of invention Nikola Tesla, elegant, highly eccentric, a dreamer who revolutionized the generation and delivery of electricity; and the charismatic George Westinghouse, Pittsburgh inventor and tough corporate entrepreneur, an industrial idealist who in the era of gaslight imagined a world powered by cheap and plentiful electricity and worked heart and soul to create it. Edison struggled to introduce his radical new direct current (DC) technology into the hurly-burly of New York City as Tesla and Westinghouse challenged his dominance with their alternating current (AC), thus setting the stage for one of the eeriest feuds in American corporate history, the War of the Electric Currents. The battlegrounds: Wall Street, the 1893 Chicago World’s Fair, Niagara Falls, and, finally, the death chamber - Jonnes takes us on the tense walk down a prison hallway and into the sunlit room where William Kemmler, convicted ax murderer, became the first man to die in the electric chair. Empires of Light is the gripping history of electricity, the “mysterious fluid,” and how the fateful collision of Edison, Tesla, and Westinghouse left the world utterly transformed.

    Dick is the magnificent and imaginative final work of an author who dedicated his life to questioning the nature of reality and perception, the malleability of space and time, and the relationship between the human and the divine. Edited and introduced by Pamela Jackson and Jonathan Lethem, this will be the definitive presentation of Dick’s brilliant, and epic, final work. In The Exegesis, Dick documents his eight-year attempt to fathom what he called "2-3-74," a postmodern visionary experience of the entire universe "transformed into information." In entries that sometimes ran to hundreds of pages, Dick tried to write his way into the heart of a cosmic mystery that tested his powers of imagination and invention to the limit, adding to, revising, and discarding theory after theory, mixing in dreams and visionary experiences as they occurred, and pulling it all together in three late novels known as the VALIS trilogy. In this abridgment, Jackson and Lethem serve as guides, taking the reader through the Exegesis and establishing connections with moments in Dick’s life and work.

    Check out the weird and wonderful facts in this massive encyclopedia of alphabetized oddities:* HUMANS ARE THE ONLY ANIMALS THAT ENJOY SPICY FOOD (there’s a reason no one sells Tabasco-flavored cat food)* NAPPING CAN SAVE YOU FROM A HEART ATTACK (assuming you are not operating heavy machinery at the time)* PSYCHOLOGISTS CAN ASSESS YOUR PERSONALITY FROM HOW YOU DIP FRIES IN KETCHUP (nice fries, sociopath)* SURFING THE INTERNET ACTUALLY MAKES YOU SMARTER (but not as smart as reading this book will)Now the next time someone tells you smugly that Pluto isn’t a planet,you can counter with any one of these hundreds of weird facts and remain king or queen of the cocktail (or kegger) chatter.

    The fantastic journey began in 1977, before the first episode of Cosmos aired. The mission was planned as a grand tour beyond the moon; beyond Mars, Jupiter, and Saturn; and maybe even into interstellar space. The fact that it actually happened makes this humanity's greatest space mission.In The Interstellar Age, award-winning planetary scientist Jim Bell reveals what drove and continues to drive the members of this extraordinary team, including Ed Stone, Voyager's chief scientist and the one-time head of NASA's Jet Propulsion Lab; Charley Kohlhase, an orbital dynamics engineer who helped to design many of the critical slingshot maneuvers around planets that enabled the Voyagers to travel so far; and the geologist whose Earth-bound experience would prove of little help in interpreting the strange new landscapes revealed in the Voyagers' astoundingly clear images of moons and planets.Speeding through space at a mind-bending eleven miles a second, Voyager 1 is now beyond our solar system's planets. It carries with it artifacts of human civilization. By the time Voyager passes its first star in about 40,000 years, the gold record on the spacecraft, containing various music and images including Chuck Berry's "Johnny B. Goode," will still be playable.

    How many of us understand the way seizures affect the brain, how the heart is connected to wellbeing, or the why the foot carries the key to our humanity?

At its heart, Adventures in Human Being is a meditation on what it means to be human. Poetic, eloquent, and profoundly perceptive, this book will transform the way you view your body.

    A religious conference has been called in nearby Rudolstadt which will determine doctrine for all the Lutherans in the nation. The hard-fought principle of religious freedom is at stake, threatened alike by intransigent theologians and students rioting in the streets.As if that weren't bad enough:* the up-time American Lutherans are themselves divided;* a rambunctious old folk singer is cheerfully pouring gasoline on the flames;* and a Calvinist "facilitator" from Geneva is maneuvering to get the U.S. involved with the developing revolutionary movement in Naples.Stories include:* Portraits by Eric Flint* Anna's Story by Loren Jones* Curio and Relic by Tom Van Natta* The Sewing Circle by Gorg Huff* The Rudolstadt Colloquy by Virginia DeMarce* Radio in the 1632 Universe by Rick Boatright* They've Got Bread Mold, So Why Can't They Make Penicillin? by Robert Gottlieb* Horse Power by Karen Bergstralh

    Conceived, written, and directed by a little-known filmmaker named George Lucas, the movie originally called The Star Wars quickly drew blocks-long lines, bursting box-office records and ushering in a new way for movies to be made, marketed, and merchandised. It is now one of the most adored-and successful-movie franchises of all time.Now, the author of the bestselling biography Jim Henson delivers a long-awaited, revelatory look into the life and times of the man who created Luke Skywalker, Han Solo, and Indiana Jones.If Star Wars wasn't game-changing enough, Lucas went on to create another blockbuster series with Indiana Jones, and he completely transformed the world of special effects and the way movies sound. His innovation and ambition forged Pixar and Lucasfilm, Industrial Light & Magic, and THX sound.Lucas's colleagues and competitors offer tantalizing glimpses into his life. His entire career has been stimulated by innovators including Steven Spielberg and Francis Ford Coppola, actors such as Harrison Ford, and the very technologies that enabled the creation of his films-and allowed him to keep tinkering with them long after their original releases. Like his unforgettable characters and stories, his influence is unmatched.

    Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.

    He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world—they did not understand what there is to understand, or how to understand it. Yet over the centuries, through the struggle to solve such mysteries as the curious backward movement of the planets and the rise and fall of the tides, the modern discipline of science eventually emerged. Along the way, Weinberg examines historic clashes and collaborations between science and the competing spheres of religion, technology, poetry, mathematics, and philosophy.An illuminating exploration of the way we consider and analyze the world around us, To Explain the World is a sweeping, ambitious account of how difficult it was to discover the goals and methods of modern science, and the impact of this discovery on human knowledge and development.
