    And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth’s first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean’s former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight’s menu. Anyone who enjoys the undersea world—along with all those obsessed with things prehistoric—will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

    Ceram visualized archeology as a wonderful combination of high adventure, romance, history and scholarship, and this book, a chronicle of man's search for his past, reads like a dramatic narrative. We travel with Heinrich Schliemann as, defying the ridicule of the learned world, he actually unearths the remains of the ancient city of Troy. We share the excitement of Lord Carnarvon and Howard Carter as they first glimpse the riches of Tutankhamen's tomb, of George Smith when he found the ancient clay tablets that contained the records of the Biblical Flood. We rediscover the ruined splendors of the Hanging Gardens of Babylon, one of the wonders of the ancient wold; of Chichen Itza, the abandoned pyramids of the Maya: and the legendary Labyrinth of tile Minotaur in Crete. Here is much of the history of civilization and the stories of the men who rediscovered it.From the Paperback edition.

    

    Our sense of its age was vague and vastly off the mark, and much of the knowledge of our own species’ history was a set of fantastic myths and fairy tales. In the tradition of The Microbe Hunters and Gods, Graves, and Scholars, Sean Carroll leads a rousing voyage that recounts the most important discoveries in two centuries of natural history: from Darwin’s trip around the world to Charles Walcott’s discovery of pre-Cambrian life in the Grand Canyon; from Louis and Mary Leakey’s investigation of our deepest past in East Africa to the trailblazers in modern laboratories who have located a time clock in our DNA.

    Outer Hebrides, 600 acres . . . Puffins and seals. Apply . . . ”.In this radiant and powerful book, Adam describes, and relives, his love affair with this enchantingly beautiful property, which he inherited when he was twenty-one. As the islands grew to become the most important thing in his life, they began to offer him more than escape, giving him “sea room”—a sailing term Nicolson uses to mean “the sense of enlargement that island life can give you.”The Shiants—the name means holy or enchanted islands—lie east of the Isle of Lewis in a treacherous sea once known as the “stream of blue men,” after the legendary water spirits who menaced sailors there. Crowned with five-hundred-foot cliffs of black basalt and surrounded by tidal rips, teeming in the summer with thousands of sea birds, they are wild, dangerous, and dramatic—with a long, haunting past. For millennia the Shiants were a haven for those seeking solitude—an eighth-century hermit, the twentieth-century novelist Compton Mackenzie—but their rich, sometimes violent history of human habitation includes much more. Since the Stone Age, families have dwelled on the islands and sailors have perished on their shores. The landscape is soaked in centuries-old tales of restless ghosts and ancient treasure, cradling the heritage of a once productive world of farmers and fishermen.In passionate, keenly precise prose, Nicolson evokes the paradoxes of island life: cut off from the mainland yet intricately bound to it, austere yet fertile, unforgiving yet bewitchingly beautiful.Sea Room does more than celebrate and praise this extraordinary place. It shares with us the greatest gift an island can bestow: a deep, revelatory engagement with the natural world.

    They took three billion man-hours to build. And even though most are crumbling today, they contain a magnificent scientific and cultural story—about the geothermal forces that formed their stones, the tectonic movements that brought them to the surface, the glacial tide that broke them apart, the earth that held them for so long, and about the humans who built them.Stone walls tell nothing less than the story of how New England was formed, and in Robert Thorson's hands they live and breathe. "The stone wall is the key that links the natural history and human history of New England," Thorson writes. Millions of years ago, New England's stones belonged to ancient mountains thrust up by prehistoric collisions between continents. During the Ice Age, pieces were cleaved off by glaciers and deposited—often hundreds of miles away—when the glaciers melted. Buried again over centuries by forest and soil buildup, the stones gradually worked their way back to the surface, only to become impediments to the farmers cultivating the land in the eighteenth century, who piled them into "linear landfills," a place to hold the stones. Usually the biggest investment on a farm, often exceeding that of the land and buildings combined, stone walls became a defining element of the Northeast's landscape, and a symbol of the shift to an agricultural economy.Stone walls layer time like Russian dolls, their smallest elements reflecting the longest spans, and Thorson urges us to study them, for each stone has its own story. Linking geological history to the early American experience, Stone by Stone presents a fascinating picture of the land the Pilgrims settled, allowing us to see and understand it with new eyes.

    Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process.Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.

    His adventures range across Utah, Arizona, New Mexico, and southwestern Colorado, and illuminate the mysteries of the Ancestral Puebloans and their contemporary neighbors the Mogollon and Fremont, as well as of the more recent Navajo and Comanche.

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    Now, using advanced imaging technology, scientists have solved the mystery of its intricate workings. Unmatched in complexity for a thousand years, the mechanism functioned as the world's first analog computer, calculating the movements of the sun, moon, and planets through the zodiac. In Decoding the Heavens, Jo Marchant details for the first time the hundred-year quest to decode this ancient computer. Along the way she unearths a diverse cast of remarkable characters--ranging from Archimedes to Jacques Cousteau--and explores the deep roots of modern technology, not only in ancient Greece, but in the Islamic world and medieval Europe. At its heart, this is an epic adventure story, a book that challenges our assumptions about technology development through the ages while giving us fresh insights into history itself.
