A "thought-provoking and reflective" (Nature) exploration of the age-old complicity between sky watchers and war fighters from the author of Astrophysics to People in a Hurry.

In this fascinating foray into the millennia-long relationship between science and military power, astrophysicist Neil deGrasse Tyson and writer Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. The astrophysicists and military planners care about many of the same things: multi-spectral detection, ranging, tracking, imaging, nuclear fusion and access to space. Spanning early celestial navigation to satellite-enabled warfare, Accessory to War examines the intersection of science, technology, industry and power that will introduce Tyson s millions of fans to yet another dimension of how the universe has shaped our lives and our world.
