Not only essential, they have been an inspiration throughout our history. In breathtaking photographs and stories we are taken on a journey from the boreal forest at the edge of the Arctic to the rainforests girdling the planet; from ancient bristlecones to fresh-leaved seedlings; from the charming and familiar to the scary and rare. An elegantly written and highly accessible text is complemented by an extraordinary collection of images created by some of the world's leading nature photographers.

    A total eclipse of the Sun will be visible from within a narrow corridor that traverses the United States. The path of the Moon's umbral shadow will begin in the northern Pacific and cross the USA from west to east from Oregon to South Carolina. The Moon's penumbral shadow will produce a partial eclipse visible from most of North America. In fact, the 2017 full eclipse is such an important sky event that sky watchers in Europe are already planning trips to view it. 2017 Guide to the Night Sky provides all of the information needed to view this exciting eclipse and track its path. The time zones and transit of the eclipse will be noted inside the book's jacket for quick and easy reference.The night sky makes for exciting viewing any time of the year, and 2017 Guide to the Night Sky is the ideal guide to help amateur astronomers find their way for the entire 12 months. With monthly charts and other diagrams set for a latitude of 40 degrees North, it shows how the visible stars change from month to month and includes the many sky events that occur throughout the year. It is highly practical for beginning sky gazers because the objects and events may be observed with the naked eye, or nothing more complicated than a pair of binoculars.The month-by-month guides include sky activity charts and moon calendars; meteors (with dates of showers, including hourly rate of radiants); the Planets; ecliptic charts; diagrams of interesting events; plus sky and constellation maps throughout.An appendix includes a full glossary; the Greek Alphabet; the constellation genitives, abbreviations and English names; a table of common asterisms; further information; recommended astronomy journals, societies, institutions and organizations; software, and internet sources.Especially useful for beginning sky watchers, this guide will be fully updated to 2017. Its small and light format makes it the ideal portable reference for backyard astronomers.

    Their creatures, ranging from the exotic to the familiar, the elegant to the whimsical, will both inspire the beginner and challenge the most accomplished folder.Choose among the dolphin, penguin, swan, owl, goose, kangaroo, praying mantis, or even the mythical Pegasus or extinct wooly mammoth. Each of these thirty-seven new projects is true origami-folded from a single piece of paper with no cutting or gluing-and is complete with clear step-by-step diagrams, instructions, and a photograph of the finished model.Origami Zoo will challenge and delight anyone with a penchant for creating something wonderful out of (almost) nothing.

    In this refreshing work of history and analysis, data scientist Alexander Boxer examines classical texts on astrology to expose its underlying scientific and mathematical framework. Astrology, he argues, was the ancient world’s most ambitious applied mathematics problem, a grand data-analysis enterprise sustained by some of history’s most brilliant minds from Ptolemy to al-Kindi to Kepler.A “scheme of heaven,” or horoscope, is recognized as pseudoscience today, but was once considered a cutting-edge scientific tool. Not only does Boxer trace different applications of horoscopes back to their origins, he also puts them to the test using modern data sets and statistical science, arguing that today’s data scientists do work similar to astrologers of yore.At once critical, rigorous, and far-ranging, A Scheme of Heaven recontextualizes astrology as a vast, technological project—spanning continents and centuries—that foreshadowed our data-driven world today.
