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.

A wonderful selection of wave and ripple designs curated bySatoshi Nakamoto, the renowned creator of the digital currency Bitcoin. These beautiful illustrations are based on work by the Japanese artist Mori Yuzan, which has been carefully restored and reproduced to near original quality for Mr. Nakamoto's private collection. Yuzan's designs were often used by Japanese craftsmen in the early 1900s to adorn their wares with wave and ripple patterns, and as decorative motifs on the handles and blades of samurai swords and other fine objects like furniture, lacquerware and miniature sculptures.

Colin Everroad should be dead, but after his lobster boat founders during a violent storm off the Maine coast, he wakes up on a beach. He's cold, but unscathed... with strange memories of a face he can't conjure and a voice he doesn't recognize. No one can explain it, but a friend suggests Colin was saved by one of the mer. Except the mer don't exist. Do they? But... that face. That voice. Someone was in the water with him. Someone saved him. If not a mer, then who? And whoever it was, Colin wants to see his face. Lir broke protocol by rescuing a land person, but he couldn't just let the man drown. When he disobediently resurfaces to see his beautiful land man, he knows it's only a matter of time before he's forbidden to leave the depths again. One clandestine visit turns into more. Soon, Colin and Lir are meeting at the shore as often as possible, and the connection between them deepens. The only problem is that neither can live in the other's world. Or can they? Then Lir finds a way for them to be together, but only for a little while... and at a cost. As time grows short, they have to choose: does Lir return to the sea and never see Colin again, or stay forever with the man he loves in a world that will never love them? Ripples & Waves is a modern, queer retelling of Hans Christian Andersen's The Little Mermaid.

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 reviews: "...This is an extremely useful reference text for the sedimentary geologist to own. It is well produced with clear illustrations and text, and gives excellent factual information on a large number of topics." (Palaeogeography, Palaeoclimatology, Palaeoecology) "...represents a significant contribution to the literature of geoscience. It should be in the library of anyone seriously intereted in sedimentology."(Marine Geology) "This book is still unsurpassed in providing a good, basic synthesis of modern sedimentary environments, especially the physical attributes of the deposits being formed and the processes responsible..." (Sedimentary Geology)

On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever. Until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays and the rest. But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead. At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.
