Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles.This completely new translation, the first in 270 years, is based on the third (1726) edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system.The illuminating Guide to the Principia by I. Bernard Cohen, along with his and Anne Whitman's translation, will make this preeminent work truly accessible for today's scientists, scholars, and students.

    How to Fish is a gem of a book that gets to the heart of the passion for angling: that there's more to fishing than catching fish.

    Konrad Lorenz was gifted with a similar power of understanding the animal world. He was that rare beast, a brilliant scientist who could write (and indeed draw) beautifully. He did more than any other person to establish and popularize the study of how animals behave, receiving a Nobel Prize for his work. King Solomon's Ring, the book which brought him worldwide recognition, is a delightful treasury of observations and insights into the lives of all sorts of creatures, from jackdaws and water-shrews to dogs, cats and even wolves. Charmingly illustrated by Lorenz himself, this book is a wonderfully written introduction to the world of our furred and feathered friends, a world which often provides an uncanny resemblance to our own. A must for any animal-lover!

    bataar bones he was impressed. The enormous skull and teeth betrayed the apex predators close relation to the storied Tyrannosaurus rex, the most famous animal that ever lived. Prokopi's obsession with fossils had begun decades earlier, when he was a Florida boy scouring for shark teeth and Ice Age remnants, and it had continued as he built a thriving business hunting, preparing, and selling specimens to avid collectors and private museums around the world. To scientists' fury and dismay, there was big money to be made in certain corners of the fossil trade. Prokopi didn't consider himself merely a businessman, though. He also thought of himself as a vital part of paleontology--as one of the lesser-known artistic links in bringing prehistoric creatures back to life--and saw nothing wrong with turning a profit in the process. Bone hunting was expensive, risky, controversial work, and he increasingly needed bigger "scores." By the time he acquired a largely complete skeleton of T. bataar and restored it in his workshop, he was highly leveraged and drawing quiet scorn from peers who worried that by bringing such a big, beautiful Mongolian dinosaur to market he would tarnish the entire trade. Presenting the skeleton for sale at a major auction house in New York City, he was relieved to see the bidding start at nearly $1 million---only to fall apart when the president of Mongolia unexpectedly stepped in to question the specimen's origins and demand its return. An international custody battle ensued, shining new light on the black market for dinosaur fossils, the angst of scientists who fear for their field, and the precarious political tensions in post-Communist Mongolia. The Prokopi case, unprecedented in American jurisprudence, continues to reverberate throughout the intersecting worlds of paleontology, museums, art, and geopolitics.

    But when Paco was struck down by a disease that left him unable to walk, Hickam was faced with a terrible decision, let his beloved cat live in misery or put him to sleep. Before that decision could be made, the space mission Hickam was working on needed to be rescued and there was only one sure way to save it: Paco's magic meow! This is a true story of the space age that is also a delightful tale of the love between an engineer and his cat.

    It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

    But what if these beings were more than merely fictions? What if monstrous creatures once roamed the earth in the very places where their legends first arose? This is the arresting and original thesis that Adrienne Mayor explores in The First Fossil Hunters. Through careful research and meticulous documentation, she convincingly shows that many of the giants and monsters of myth did have a basis in fact--in the enormous bones of long-extinct species that were once abundant in the lands of the Greeks and Romans.As Mayor shows, the Greeks and Romans were well aware that a different breed of creatures once inhabited their lands. They frequently encountered the fossilized bones of these primeval beings, and they developed sophisticated concepts to explain the fossil evidence, concepts that were expressed in mythological stories. The legend of the gold-guarding griffin, for example, sprang from tales first told by Scythian gold-miners, who, passing through the Gobi Desert at the foot of the Altai Mountains, encountered the skeletons of Protoceratops and other dinosaurs that littered the ground.Like their modern counterparts, the ancient fossil hunters collected and measured impressive petrified remains and displayed them in temples and museums; they attempted to reconstruct the appearance of these prehistoric creatures and to explain their extinction. Long thought to be fantasy, the remarkably detailed and perceptive Greek and Roman accounts of giant bone finds were actually based on solid paleontological facts. By reading these neglected narratives for the first time in the light of modern scientific discoveries, Adrienne Mayor illuminates a lost world of ancient paleontology. As Peter Dodson writes in his Foreword, "Paleontologists, classicists, and historians as well as natural history buffs will read this book with the greatest of delight--surprises abound."

    It would become the world's most baffling mathematical mystery. Simple, elegant, and utterly impossible to prove, Fermat's Last Theorem captured the imaginations of amateur and professional mathematicians for over three centuries. For some it became a wonderful passion. For others it was an obsession that led to deceit, intrigue, or insanity. In a volume filled with the clues, red herrings, and suspense of a mystery novel, Dr. Amir Aczel reveals the previously untold story of the people, the history, and the cultures that lie behind this scientific triumph. From formulas devised for the farmers of ancient Babylonia to the dramatic proof of Fermat's theorem in 1993, this extraordinary work takes us along on an exhilarating intellectual treasure hunt. Revealing the hidden mathematical order of the natural world in everything from stars to sunflowers, "Fermat's Last Theorem" brilliantly combines philosophy and hard science with investigative journalism. The result: a real-life detective story of the intellect, at once intriguing, thought-provoking, and impossible to put down.
