Seashells are the sculpted homes of a remarkable group of animals: the molluscs. These are some of the most ancient and successful animals on the planet. But watch out. Some molluscs can kill you if you eat them. Some will kill you if you stand too close. That hasn't stopped people using shells in many ways over thousands of years. They became the first jewelry and oldest currencies; they've been used as potent symbols of sex and death, prestige and war, not to mention a nutritious (and tasty) source of food. Spirals in Time is an exuberant aquatic romp, revealing amazing tales of these undersea marvels. Helen Scales leads us on a journey into their realm, as she goes in search of everything from snails that 'fly' underwater on tiny wings to octopuses accused of stealing shells and giant mussels with golden beards that were supposedly the source of Jason's golden fleece, and learns how shells have been exchanged for human lives, tapped for mind-bending drugs and inspired advances in medical technology. Weaving through these stories are the remarkable animals that build them, creatures with fascinating tales to tell, a myriad of spiralling shells following just a few simple rules of mathematics and evolution. Shells are also bellwethers of our impact on the natural world. Some species have been overfished, others poisoned by polluted seas; perhaps most worryingly of all, molluscs are expected to fall victim to ocean acidification, a side-effect of climate change that may soon cause shells to simply melt away. But rather than dwelling on what we risk losing, Spirals in Time urges you to ponder how seashells can reconnect us with nature, and heal the rift between ourselves and the living world.

Im Kopf eines Genies – der Bericht von einem mathematischen Abenteuer und der Roman eines sehr erfolgreichen Forschers Cédric Villani gilt als Kandidat für die begehrte Fields-Medaille, eine Art Nobelpreis für Mathematiker. Sie wird aber nur alle vier Jahre vergeben, und man muss unter 40 sein. Er hat also nur eine Chance. Unmöglich! Unmöglich? Fieberhaft macht er sich an die Arbeit. Jetzt erzählt er seine Geschichte, und ihm gelingt das Unglaubliche: Wir werden direkte Zeugen der Denkprozesse eines Mathematikers, und das, ohne die dazugehörigen Formeln verstehen zu müssen. Ein Buch, so einzigartig wie sein Autor.

This book uses the spiral shape as a key to a multitude of strange and seemingly disparate stories about art, nature, science, mathematics, and the human endeavour. In a way, the book is itself organized as a spiral, with almost disconnected chapters circling around and closing in on the common theme. A particular strength of the book is its extremely cross-disciplinary nature - everything is fun, and everything is connected! At the same time, the author puts great emphasis on mathematical and scientific correctness, in contrast, perhaps, with some earlier books on spirals. Subjects include the mathematical properties of spirals, sea shells, sun flowers, Greek architecture, air ships, the history of mathematics, spiral galaxies, the anatomy of the human hand, the art of prehistoric Europe, Alfred Hitchcock, and spider webs, to name a few.

From bestselling author A.J. Banner comes a dazzling new novel of psychological suspense in the vein of S.J. Watson’s Before I Go to Sleep and Mary Kubica’s The Good Girl that questions just how much we can trust the people around us. Thirty-four-year-old marine biologist Kyra Winthrop remembers nothing about the diving accident that left her with a complex form of memory loss. With only brief flashes of the last few years of her life, her world has narrowed to a few close friendships on the island where she lives with her devoted husband, Jacob. But all is not what it seems. Kyra begins to have visions—or are they memories?—of a rocky marriage, broken promises, and cryptic relationships with the island residents, whom she believes to be her friends. As Kyra races to uncover her past, the truth becomes a terrifying nightmare. A twisty, immersive thriller, The Twilight Wife will keep readers enthralled through the final, shocking twist.

Ein Besuch der Apnoe-Weltmeisterschaft wird für James Nestor zum Beginn eines persönlichen Abenteuers: Fasziniert von der Kompromisslosigkeit dieses Sports, erlernt er selbst das Freitauchen. Und fortan zieht es ihn immer tiefer in die verborgene Welt der Ozeane hinab: Er besucht eine Forschungsstation 20 Meter unter der Meeresoberfläche, trifft renommierten Meeresbiologen bei ihrer Arbeit, schwimmt mit Walen und geht im U-Boot auf Tauchstation. Dabei entdeckt er einen unfassbar reichen Lebensraum, mit telepathischen Korallen, leuchtenden Fischen und rätselhaften Riesenkraken. Bis er schließlich den tiefsten Punkt der Erde erreicht – die absolute Grenze für Mensch und Technik. Eine grandiose Entdeckungsreise, die zugleich unseren Wurzeln nachspürt.

This is a book about the simple pleasure of pebble spotting. Clarence Ellis is a charming, knowledgeable and witty guide to everything you didn't know there was to know about pebbles. He ruminates on what a pebble actually is, before showing us how they are formed, advising on the best pebble-spotting grounds in the UK, helping to identify individual stones, and giving tips on the necessary kit. You'll know your chert from your schist, your onyx from your agate, and will be on your guard for artificial intruders before you know it. Understanding the humble pebble makes a trip to the beach, lake-side or river bank simply that little bit more fascinating.
