I began by writing science fiction stories, novels and films, before disappearing down various rabbit-holes: perception (The Eye: A Natural History), 20th-century radical politics (The Weight of Numbers), the shipping system (Dead Water) and augmented reality (Wolves). I co-founded and edited Arc magazine, a digital publication about the future, before joining New Scientist magazine as its arts editor. Now I eke out a freelance living in possibly the coldest flat in London, writing arts reviews for the newspapers. My latest non-fiction is Stalin and the Scientists, a history of Soviet science. My latest novel is The Smoke.
