Book Description
The fascinating history and unnerving future of high-tech aerial surveillance, from its secret military origins to its growing use on American citizens Eyes in the Sky is the authoritative account of how the Pentagon secretly developed a godlike surveillance system for monitoring America's enemies overseas, and how it is now being used to watch us in our own backyards. Whereas a regular aerial camera can only capture a small patch of ground at any given time, this system—and its most powerful iteration, Gorgon Stare—allow operators to track thousands of moving targets at once, both forwards and backwards in time, across whole city-sized areas. When fused with big-data analysis techniques, this network can be used to watch everything simultaneously, and perhaps even predict attacks before they happen. In battle, Gorgon Stare and other systems like it have saved countless lives, but when this technology is deployed over American cities—as it already has been, extensively and largely in secret—it has the potential to become the most nightmarishly powerful visual surveillance system ever built. While it may well solve serious crimes and even help ease the traffic along your morning commute, it could also enable far more sinister and dangerous intrusions into our lives. This is closed-circuit television on steroids. Facebook in the heavens. Drawing on extensive access within the Pentagon and in the companies and government labs that developed these devices, Eyes in the Sky reveals how a top-secret team of mad scientists brought Gorgon Stare into existence, how it has come to pose an unprecedented threat to our privacy and freedom, and how we might still capitalize on its great promise while avoiding its many perils.

Book Description
Reviews for the previous editions: Among the many good books on binocular astronomy, Stargazing with Binoculars stands out as one of the best. [Scagell and Frydman] pack an amazing amount of information into a volume that's clearly written, entertaining, attractive, and portable. --Sky and Telescope A serious contender for the title of best all-around introduction to binocular astronomy. --Sky and Telescope Stargazing with Binoculars is the ideal guide for newcomers to astronomy. The authors review the range of the latest binoculars on the market and provide advice on features to consider before making a purchase. Then they lead the beginner through the first steps of using binoculars to observe the night sky, describing what will be visible and how to find specific objects. This edition has been thoroughly updated to incorporate the latest binocular technology. Illustrated throughout and packed with handy tips and tricks, the book includes: How binoculars work and what to expect Buying for the first time and upgrading The wide range of binoculars available internationally Using different sizes of binoculars The effects of light pollution Observing the Sun, Moon, planets, comets, asteroids, stars, clusters, variable stars, double stars, novae, nebulae and galaxies Guidance for observing in the city and in the country Glossary of terms. Binoculars are portable and financially accessible, whereas a telescope can be costly and unwieldy. Even binoculars without bells and whistles will give the viewer an exciting look into the night sky. This introduction is the ideal guide in that pursuit.

Book Description
The effects of light pollution on flora, fauna -including humans and their widely varying night-time activities- are often subtle and need extensive field studies to be quantified in a sensible manner. Some of the highlights were: The presentation of the 1st world atlas of artificial night sky brightness (Cinzano et al.); the article by the International Darksky Association on their world-wide efforts to curb light pollution (Alvarez del Castillo et al.); the laws controlling light pollution implemented in Spain (Diaz et al.) and Chile (Sanhueza et al.), an overview of the work on radio frequency protection of sites (Cohen et al.) and the excellent introduction to the topic from the Chilean point of view (Daud). Related topics in the book are light pollution education, aircraft contrails, space advertising (with an added document provided by the relevant UN commission), and an experiment on involving the population of an entire country in measuring sky brightness, by using the internet and the media. The text is aimed at professionals from a wide range of disciplines related to lighting and its effects on the night-time environment in the broadest sense of the word. Lay persons interested in this emerging multi-disciplinary field can also find much of interest in this book.
