In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

    Unlike their human counterparts, who must alter their environment to accommodate our physical limitations, animals are adaptable to an amazing range of conditions--i.e., radical changes in a creature's physiology take place to match the demands of the environment. Winter provides an especially remarkable situation, because of how drastically it affects the most elemental component of all life: water.Examining everything from food sources in the extremely barren winter landscape to the chemical composition that allows certain creatures to survive, Heinrich's Winter World awakens the largely undiscovered mysteries by which nature sustains herself through the harsh, cruel exigencies of winters

    This field guide is divided into two large sections -- one devoted to minerals and one to rocks, each prefaced by a comprehensive introduction that discusses formation, chemistry, and more. All 377 entries, beautifully illustrated with color photographs and helpful visual symbols, provide descriptions and practical information about appearance, classification, rarity, crystal formation, mode of occurrence, gravity of mineral, rock chemistry, modal classification fields, formational environments, grain sizes of rocks, and much more. Whether you are a serious collector or an information-seeking amateur, this incomparably beautiful, authoritative guide will prove an invaluable reference.

    In this book, he expands the points he has made, and claims that this debate is not so much about religion versus science, as about the nature of science itself. With infectious enthusiasm, he reveals the mechanics of evolutionary theory, explains how it is rooted in the testable and verifiable scientific method, and why it is therefore a sound explanation of our beginning. He argues passionately that to continue to assert otherwise, to continue to insist that creationism has a place in the science classroom is harmful not only to our children, but to the future of the greater world as well.

    The descriptive text includes information on size, geological period, geographical distribution, and ecology of the animal or plant before it was fossilized. In addition, the book provides lists of Geological Survey offices and major fossil collections, a geological time chart, and a guide to collecting and preserving fossils.

    Shows and describes more than eight hundred species, and provides information on distribution, characteristics, and behavior.

    And the first step is to start looking after the insects, the little creatures that make our shared world go round. Insects are essential for life as we know it. As they become scarcer, our world will slowly grind to a halt; we simply cannot function without them. Drawing on the latest ground-breaking research and a lifetime's study, Dave Goulson reveals the shocking decline of insect populations that has taken place in recent decades, with potentially catastrophic consequences. He passionately argues that we must all learn to love, respect, and care for our six-legged friends. Eye-opening, inspiring, and riveting, Silent Earth is part love letter to the insect world, part elegy, part rousing manifesto for a greener planet. It is a call to arms for profound change at every level--in government policy, agriculture, industry, and in our own homes and gardens. Although time is running out, it is not too late for insect populations to recover. We may feel helpless in the face of many of the environmental issues that loom on the horizon, but Goulson shows us how we can take simple steps to encourage insects and counter their destruction.

    This guide shows how to recognize hawks the way we recognize friends at a distance: by body shape, movements, and locale.

    The authors include a broad range of contemporary applications to motivate students understanding of how physics works in the real world. In addition, new pedagogy, reflecting the findings of physics education research, has been added to help students improve their problem solving skills and conceptual understanding. The text's flexible, accessible, and focused presentation, coupled with extraordinary text/media integration through PhysicsNow, gives instructors and students the tools they need to succeed. This text, which covers the standard topics in classical physics and 20th century physics, is divided into six parts. Newtonian mechanics and the physics of fluids (Part I); heat and thermodynamics (Part II); wave motion and sound (Part III); electricity and magnetism (Part IV); properties of light and the field of geometric and wave optics (Part V); and an introduction to special relativity, quantum physics, and atomic and nuclear physics (Part VI).

    An attractive and comprehensive guidebook, this work has been completely revised and updated by the author. The reader will find an easy-to-use text which details the natural history of the plants and animals found in the Galápagos Islands. Management and conservation of the Galápagos National Park is discussed, and visitor information and notes about the various tourist sites are given. An index and checklist of plants and animals with page references and a glossary of technical terms are provided. New photographs have been added.

    Key features include:- use of compatible perennials;- non-invasive planting techniques;- emphasis on biodiversity;- specifically adaptable to local climate, landscape, and soil conditions;- highly productive output of edibles.Now, picture your backyard as one incredibly lush garden, filled with edible flowers, bursting with fruit and berries, and carpeted with scented herbs and tangy salad greens. The visual impact is of Monet's palette, a wash of color, texture, and hue. But this is no still life. The flowers nurture endangered pollinators. Bright-featured songbirds feed on abundant berries and gather twigs for their nests.The plants themselves are grouped in natural communities, where each species plays a role in building soil, deterring pests, storing nutrients, and luring beneficial insects. And finally, you—good ol' homo sapiens—are an integral part of the scene. Your garden tools are resting against a nearby tree, and have a slight patina of rust, because this garden requires so little maintenance. You recline into a hammock to admire your work. You have created a garden paradise.This is no dream, but rather an ecological garden, which takes the principles of permaculture and applies them on a home-scale. There is nothing technical, intrusive, secretive, or expensive about this form of gardening. All that is required is some botanical knowledge (which is in this book) and a mindset that defines a backyard paradise as something other than a carpet of grass fed by MiracleGro.

    To Lee Goff and his fellow forensic entomologists, each body recovered at a crime scene is an ecosystem, a unique microenvironment colonized in succession by a diverse array of flies, beetles, mites, spiders, and other arthropods: some using the body to provision their young, some feeding directly on the tissues and by-products of decay, and still others preying on the scavengers.Using actual cases on which he has consulted, Goff shows how knowledge of these insects and their habits allows forensic entomologists to furnish investigators with crucial evidence about crimes. Even when a body has been reduced to a skeleton, insect evidence can often provide the only available estimate of the postmortem interval, or time elapsed since death, as well as clues to whether the body has been moved from the original crime scene, and whether drugs have contributed to the death.An experienced forensic investigator who regularly advises law enforcement agencies in the United States and abroad, Goff is uniquely qualified to tell the fascinating if unsettling story of the development and practice of forensic entomology.

    Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, Honeybee Democracy brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees.In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together--as a swirling cloud of bees--to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution.An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.
