PositiveScience NewsTyson and Lang’s millennia-long world history is sprawling. The book is exhaustively researched, almost to the point of information overload. It’s easy to get bogged down in parenthetical asides about minor characters or paragraph-long lists. The book is the antithesis of Tyson’s starry-eyed, bite-sized Astrophysics for People in a Hurry and may end up on the shelves of more history buffs than astro nerds. Still, Accessory to War lives up to much of the promise of a Neil deGrasse Tyson read: Written from Tyson’s perspective, the narration is rich with wry humor and vivid descriptions of cosmic goings-on. For anyone who is, like Tyson, \'smitten by the cosmos,\' the book is a stark reminder that astrophysics has been both a benefactor and beneficiary of human conflict—and that the final frontier will likely be the battleground of many future skirmishes.
