     Some people think monsters are the stuff of nightmares--the stuff of scary movies and Halloween. But monsters can also be found right in your backyard. Animals like aye-ayes, goblin sharks and vampire bats may look scary, but they pose no threat to humans. Others, such as the prairie dog, seem innocent--cute, even--yet their behavior could give you goose bumps. What makes a monster? Read this book to find out, if you dare. . . . Jess Keating and David DeGrand, the author illustrator team behind Pink Is for Blobfish will have readers shrieking with laughter at this latest installment to the World of Weird Animals series.

    No one seemed able to agree on a cause. (Dark matter? Tensor–vector–scalar gravity? Collisions with gravitons?) What did seem clear to those who became obsessed with it was that the Pioneer Anomaly had the potential to upend Einstein and Newton—to change everything we know about the universe.With riveting prose and the precision of an expert, Konstantin Kakaes gives us a scientific police procedural, tracking the steps of those who sought to unravel this high-stakes enigma. His thrilling account draws on extensive interviews and archival research, following the story from the Anomaly’s initial discovery, through decades of tireless investigation, to its ultimate conclusion. “The Pioneer Detectives” is a definitive account not just of the Pioneer Anomaly but of how scientific knowledge gets made and unmade, with scientists sometimes putting their livelihoods on the line in pursuit of cosmic truth. Perfect for fans of John McPhee, Thomas Kuhn, and Ed McBain, this is also an immensely enjoyable story accessible to anyone who loves brilliant, fascinating long-form journalism.* * * ABOUT THE AUTHOR: Konstantin Kakaes is a Bernard L. Schwartz fellow at the New America Foundation, writing about science and technology, and is the former Mexico City bureau chief for The Economist. His work has been published in The Wall Street Journal, Foreign Policy, and The Washington Post and appears frequently in Slate. Before becoming a journalist, he studied physics at Harvard University.

    The opening section, Ninety Years of Mapping at National Geographic, traces the founding of Geographic cartography to the present advances in technology and the practice of compiling and organizing geographic information. The atlas truly begins with three stunning new, full-spread world maps, that drape Earth's surface seamlessly with satellite imagery, then physical and natural features, and finally today's political world of countries and growing cities.World thematic topics are organized into two groups: the Physical and Natural World and Human Activities. The Physical and Natural World section includes captivating core topics such as the evolution of earth, geology and tectonics, climate and weather, oceans, world water, the bioshere, and biodiversity. Human Activities covers 11 world themes: population, migration and refugees, conflict and terrorism, cultures, economy, energy and minerals, communications, food, health and education, the environment, and ending with wildlands. All of these intriguing spreads reflect the most authoritative and recent data available and are reviewed by preeminent scholars and experts. Lined up after the world thematic focus is the continental division. All seven continents open with views from space and are then represented with separate physical and political maps. Larger scale regions of each continent are presented for higher definition and detail. Because of our primary readership, additional coverage is given to the UnitedStates and Canada. An entirely new component to the Eighth Edition is the city section. Maps and text discussing urban explosion will open this compilation of sixty new maps. Pictures, fact boxes, and text will accompany each city map to create colorful and informative portraits of our built environment. Selected cites such as, New York, Mexico City-the most densely populated city in the world, and Paris will receive more detailed scaling. Less familiar and remote areas of the world and beyond-the poles, the ocean floors, and space-are mapped with new data and findings and dramatic effects. The addition of a new spread and map devoted to Mars will provide a timely reference to the expected news coverage of NASA's Mars Exploration Rover Mission-Spirit and Opportunity. Flags and facts of every country in the world have been newly designed and consolidated into one section, listed in alphabetical order. Locater maps and cross referencing to corresponding large-scale map plates are provided for every entity. Text for each independent country summarizes physical and cultural aspects, while facts reveal the status of population, religion, area, capital, language, literacy, life expectancy, GDP, and economy. A user-friendly, 136 page, comprehensive place-name index cross-references over 130,000 geographical sites and areas. An appendix presents valuable, convenient reference to time zones, metric conversions, foreign terms, abbreviations, airline distances, and temperature and rainfall statistics from all corners of the globe. Navigating throughout the atlas is made easy with enhanced cross-referencing, pointers, labels and an end sheet that includes a visual key with corresponding platenumbers to all the maps. Every map spread in the atlas will include interactive features and access to up-to-the-minute updates and information via the electronic National Geographic Map Machine. Streams of information are available to us on myriad topics and on many fronts. At the same time, there is a need-greater than ever-to better understand our global culture. The Eighth Edition helps bridges the gap with a collection of maps and information that is as engaging as it is informative.

    By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.

    

    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.

    Yet this is now an established scientific fact. In The Universe Next Door, science writer Marcus Chown examines a dozen mind-bending new ideas that also fly in the face of reason--but that, according to eminent scientists, might just be crazy enough to be true. Could time run backwards? Is there a fifth dimension? Does quantum theory promise immortality? To explore these questions, Chown has interviewed some of the most imaginative and courageous people working at the forefront of science, and he has come away with a smorgasbord of mind-expanding ideas. For instance, Lawrence Schulman at New York's Clarkson University believes there could be regions in our Universe where stars unexplode, eggs unbreak and living things grow younger with every passing second. Max Tegmark, at the University of Pennsylvania, believes there could be an infinity of realities stacked together like the pages of a never-ending book (with an infinite number of versions of you, living out an infinite number of different lives). And David Stevenson of Cal Tech argues that life may exist on worlds drifting in the cold, dark abyss between the stars, worlds without suns to warm them. Indeed, these worlds may be the most common sites for life in the universe. Was our universe created by super-intelligent beings from another universe? Is there evidence of extraterrestrial life lying right beneath our feet? The Universe Next Door ponders these and many other thought-provoking questions. You may not agree with all the answers but your head will be spinning by the time you reach the last page.

    Now, two of the world's most eminent thinkers -- University of London physicists David Bohm, a former protege of Einstein's and one of the world's most respected quantum physicists, and Stanford neurophysiologist Karl Pribram, one of the architects of our modern understanding of the brain -- believe that the universe itself may be a giant hologram, quite literally a kind of image or construct created, at least in part, by the human mind. This remarkable new way of looking at the universe explains not only many of the unsolved puzzles of physics, but also such mysterious occurrences as telepathy, out-of-body and near death experiences, "lucid" dreams, and even religious and mystical experiences such as feelings of cosmic unity and miraculous healings.
