Most people live and work entirely oblivious to the fact that a myriad of ghostly ripples are passing through them all the time. Generated in the depths of space by colliding stars and black holes, exploding supernovas and quasars, these so-called gravitational waves are literally ripples in the fabric of space itself. Sweeping across the cosmos at the speed of light, they encode vital clues about the exotic systems that produced them. Predicted by Einstein over eighty years ago, but never detected in the laboratory, gravitational waves have proven elusive to scientists. In the first book for a general reader on these amazing waves, Blair and McNamara weave a thrilling tale about the race to build the first gravitational wave antenna—a challenge that has prompted physicists and astronomers to devise some of the most breathtaking technology the world has ever seen. What these scientists find will allow us to listen to the explosion of stars, the creation of black holes, even the sound of the Big Bang itself, and will undoubtedly chart a new course for astronomy in the coming millennium.

From the New York Times-bestselling author of The Secret World of Weather and The Lost Art of Reading Nature’s Signs, learn to tap into nature and notice the hidden clues all around you Before GPS, before the compass, and even before cartography, humankind was navigating. Now this singular guide helps us rediscover what our ancestors long understood—that a windswept tree, the depth of a puddle, or a trill of birdsong can help us find our way, if we know what to look and listen for. Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.

AS ALEX PRUD’HOMME and his great-aunt Julia Child were completing their collaboration on her memoir, My Life in France, they began to talk about the French obsession with bottled water, which had finally spread to America. From this spark of interest, Prud’homme began what would become an ambitious quest to understand the evolving story of freshwater. What he found was shocking: as the climate warms and world population grows, demand for water has surged, but supplies of freshwater are static or dropping, and new threats to water quality appear every day. The Ripple Effect is Prud’homme’s vivid and engaging inquiry into the fate of freshwater in the twenty-first century. The questions he sought to answer were urgent: Will there be enough water to satisfy demand? What are the threats to its quality? What is the state of our water infrastructure—both the pipes that bring us freshwater and the levees that keep it out? How secure is our water supply from natural disasters and terrorist attacks? Can we create new sources for our water supply through scientific innovation? Is water a right like air or a commodity like oil—and who should control the tap? Will the wars of the twenty-first century be fought over water? Like Daniel Yergin’s classic The Prize: The Epic Quest for Oil, Money & Power, Prud’homme’s The Ripple Effect is a masterwork of investigation and dramatic narrative. With striking instincts for a revelatory story, Prud’homme introduces readers to an array of colorful, obsessive, brilliant—and sometimes shadowy—characters through whom these issues come alive. Prud’homme traversed the country, and he takes readers into the heart of the daily dramas that will determine the future of this essential resource—from the alleged murder of a water scientist in a New Jersey purification plant, to the epic confrontation between salmon fishermen and copper miners in Alaska, to the poisoning of Wisconsin wells, to the epidemic of intersex fish in the Chesapeake Bay, to the wars over fracking for natural gas. Michael Pollan has changed the way we think about the food we eat; Alex Prud’homme will change the way we think about the water we drink. Informative and provocative, The Ripple Effect is a major achievement.

Of all the varied and mysterious Great Old Ones of the Cthulhu Mythos, few ensnare the imagination as easily as Hastur. The image of the silent, deserted city beside a dark, foreboding lake where sinister things lurk is one that stays with the reader. Many of us have walked the twisting streets of that dead alien city in our minds, finding our way into the tall towers to stand before an ancient throne. There sits the King in Yellow, the Lord of Carcosa, who gazes at us from behind his Pallid Mask. It is a journey many of us have taken, whether alone in our dreams or around a table rolling dice with our friends. It is a journey we are about to take again.RIPPLES FROM CARCOSA expands upon the mythology of He Who Should Not Be Named and gathers much of the varied material on Hastur into one place. The first chapter reviews The Great Old One Hastur and his various avatar forms. It examines the Yellow Sign, the play The King in Yellow, the Mythos tome of the same name, and the effects these things have on the human mind.Next within these pages is a trio of adventures pitting investigators against Hastur and his human worshippers. These scenarios can be played as stand-alone adventures or as a linked campaign called Ripples from Carcosa. Investigators are provided for each scenario, but keepers should feel free to allow their players to use their own investigators if they so choose.Finally is information on the Great Old One Hastur and his cults during the Cthulhu Invictus and Cthulhu Dark Ages eras.
