I've named the years 1904-33 the "Radium Age" of science fiction because the phenomenon of radioactivity — the discovery that matter is neither solid nor still and is, at least in part, a state of energy, constantly in movement — is a timely and fitting metaphor for the first decades of the 20th century, "vertigo years" during which old scientific, religious, political, and social certainties were shattered. For a thrilling, terrifying, and all-too-brief moment, another world was possible.
Too little attention has been paid to this era's pioneering, intellectually daring, and truly enlightened science fiction. This blog — where I'm storing my ongoing research, as I simultaneously publish a series of posts about "Pre-Golden Age" SF over at the excellent SF blog io9 — aims to correct that oversight. Read a longer introduction to Radium-Age SF here.
