Paperback. Zustand: Fair. Imagine the North American Indians as astronomers carefully watching the heavens, charting the sun through the seasons, or counting the sunrises between successive lumar phases. Then imagine them establishing observational sites and codified systems to pass their knowledge down through the centuries and continually refine it. A few years ago such images would have been abruptly dismissed. Today we are wiser. Living the Sky describes the exciting archaeoastronomical discoveries in the United States in recent decades. Using history, science, and direct observation, Ray A. Williamson transports the reader into the sky world of the Indians. We visit the Bighorn Medicine Wheel, sit with a Zuni sun priest on the winter solstice, join explorers at the rites of the Hopis and the Navajos, and trek to Chaco Canyon to make direct on-site observations of celestial events. Ray Williamson is Research Professor of International Affairs and Space Policy in the Space Policy Institute, focusing on international issues in environmental security, Earth observation satellite policy, dual-purpose space technologies, and the commercialization of space-related technologies. He has conducted numerous in-depth studies of space technology and policy. From 1979 to 1995, he was a Senior Associate and Project Director in the Office of Technology Assessment of the U.S. Congress.…
