Joshua Nall has written himself a rather ambitious monograph, in that he's equally interested in how changes in what it meant to be an astronomer (mostly the rise of astrophysics as a discipline), the efflorescence of period print journalism, and technological advancements (particularly in telecommunications) all came together as a complex, and hangs the whole assemblage on the hook of the debate on whether there was intelligent life on Mars.
This is all heady stuff, and I was given a lot of food for thought, but Nall's writing style does him no favors. On one hand, he splits his hairs so fine that one can feel as though you're left with nothing. On the other, there is a certain clumsiness here that is at odds with the sophistication of the concepts, particularly when you have word choices such as "Teddy-Rooseveltian" for one to trip over. Still worth reading if one is interested in the interaction of science and public opinion.
Actual rating: 3.5.
