    Haven’t we all? What better way to break that silence than to throw out some of the incredible facts from this book.Whatever your motivation may be, there’s a really good chance you’ll find these facts and tidbits useful.

    This book is useful to students taking introductory physical geology to fulfill a science elective, as well as those contemplating a career in geology.

    But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    During his life he created numerous works of art and kept voluminous notebooks that detailed his artistic and intellectual pursuits.The collection of writings and art in this magnificent book are drawn from his notebooks. The book organizes his wide range of interests into subjects such as human figures, light and shade, perspective and visual perception, anatomy, botany and landscape, geography, the physical sciences and astronomy, architecture, sculpture, and inventions. Nearly every piece of writing throughout the book is keyed to the piece of artwork it describes.The writing and art is selected by art historian H. Anna Suh, who provides fascinating commentary and insight into the material, making Leonardo's Notebooks an exquisite single-volume compendium celebrating his enduring genius.

    1 comes a fascinating chronicle of life’s history told not through the fossil record but through the stories of organisms that have survived, almost unchanged, throughout time. Evolution, it seems, has not completely obliterated its tracks as more advanced organisms have evolved; the history of life on earth is far older—and odder—than many of us realize.   Scattered across the globe, these remarkable plants and animals continue to mark seminal events in geological time. From a moonlit beach in Delaware, where the hardy horseshoe crab shuffles its way to a frenzy of mass mating just as it did 450 million years ago, to the dense rainforests of New Zealand, where the elusive, unprepossessing velvet worm has burrowed deep into rotting timber since before the breakup of the ancient supercontinent, to a stretch of Australian coastline with stromatolite formations that bear witness to the Precambrian dawn, the existence of these survivors offers us a tantalizing glimpse of pivotal points in evolutionary history. These are not “living fossils” but rather a handful of tenacious creatures of days long gone.   Written in buoyant, sparkling prose, Horseshoe Crabs and Velvet Worms is a marvelously captivating exploration of the world’s old-timers combining the very best of science writing with an explorer’s sense of adventure and wonder.

    A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    You can not study human nature from a book, you must study yourself and your neighbors. This book may help you to know what to look for and to understand what you find, but it can do little more than this. It is true, this text gives you many facts learned by psychologists, but you must verify the statements, or at least see their significance to you, or they will be of no worth to you. However, the facts considered here, properly understood and assimilated, ought to prove of great value to you. But perhaps of greater value will be the psychological frame of mind or attitude which you should acquire. The psychological attitude is that of seeking to find and understand the causes of human action, and the causes, consequences, and significance of the processes of the human mind. If your first course in psychology teaches you to look for these things, gives you some skill in finding them and in using the knowledge after you have it, your study should be quite worth while.

    Ideal for anyone who wants to read a great work for the first time or revisit an old favorite, these new editions open the door to the stories and ideas that have shaped our world.

    This is perhaps the first time we have such a complete firsthand account in which nothing is kept back and there is no departmental “diplomacy.” The author is a nuclear power specialist who worked for a time at the Chernobyl AES and knows it well, just as he is personally acquainted with all the principal participants in the events. By virtue of his official position, he has attended many of the crucial conferences concerning nuclear power plant construction. Immediately after the accident, Medvedev was sent to Chernobyl and had an opportunity to learn a great deal while the trail was still fresh and to see things with his own eyes. He presents many technical details indispensable to understanding the mechanism whereby the accident occurred, he exposes the secrets of bureaucratic relations, he tells about the oversights of scientists and designers, about the disastrous overbearing pressure in the command system, about the violations of glasnost before the accident and in the emergency situation following it that have caused enormous harm. The chronicle of events at Chernobyl in the tragic days of April and May 1986 takes up the central place in the story. The author portrays the behavior and role of numerous participants in the drama, of real living people with their shortcomings and virtues, their doubts, their weaknesses, their illusions, and their heroism alongside the nuclear monster that had gone out of control. It is not possible to read about this without the deepest emotion. We knew about the exploits of the firemen. The author tells about the heroism of the electricians, the turbine specialists, the operators, and other workers at the station who prevented the accident from taking on greater proportions.

    Crushed and left with broken ribs, a punctured lung, and compression fractures in his chest, spine, and pelvis, Bob pushed his arms forward, dug his fingers into the freezing mud and dragged his mostly paralyzed body forward. Saturated to the skin in freezing rain, far from help, and with the night fast approaching, Bob refused to give up.This includes photographs, documentation, and inspirational verses.This amazing true story was featured on the It's a Miracle series hosted by Richard Thomas. It aired on PAX Television as Chain Reaction in 1999.

    He shows how oxygen underpins the origin of biological complexity, the birth of photosynthesis, the sudden evolution of animals, the need for two sexes, the accelerated aging of cloned animals like Dolly the sheep, and the surprisingly long lives of bats and birds. Drawing on this grand evolutionary canvas, Oxygen offers fresh perspectives on our own lives and deaths, explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas, following chains of evidence, the book ranges through many disciplines, from environmental sciences to molecular medicine. The result is a captivating vision of contemporary science and a humane synthesis of our place in nature. This remarkable book will redefine the way we think about the world.
