A new book by the famous American astrophysicist Neil DeGrasse Tyson, co-authored with Avis Lang, is devoted to the study of the long-term relationship between science and the army. What unites astrophysicists and military specialists, what are their points of intersection, how does science serve war? As it turns out, many of the discoveries and achievements of astrophysics, such as multispectral detection, range, tracking, imaging, nuclear fusion, and access to space, are not just scientific discoveries, but tools in the hands of war. From early celestial navigation to satellite wars, Neil Tyson explores the intersections of science, technology, industry and power.
