"There is a saying among astronomers that five billion people concern themselves with the surface of the Earth, and ten thousand with everything else," writes Richard Preston, best-selling author of The Hot Zone. And if you think these professional stargazers spend most of their time serenely peering into the night sky, guess again. Today's astronomers are world-class gadgeteers who scurry about giant (and often frigid) observatories tinkering with the mechanical and electronic tools of their trade. In First Light, they tangle with the Hale Telescope, one of the world's oldest and largest. This beautifully written book is highly recommended for anybody interested in astronomy.
