Why does technological speed seem to exceed the speed of cultural or natural processes? In what sense has this perceived difference impacted on human culture and the human body? This book explores the nature of technological speed and how technology becomes part of living bodies. Drawing on deconstruction and corporeal theory, it re-examines the borders between bodies and machines, between what counts as social and what counts as technological. Illustrated with examples which include online computer games, military supercomputers, genomic databases, performance art and the global positioning system - the book critiques the widely accepted notion that technology speeds everything up, arguing instead that there are only ever differences in speed.
