Mary Roach is an American popular science writer whose books investigate the science of the human body and its less glamorous processes with meticulous research and sustained, deadpan wit.
Mary Roach is the funniest science writer working in America, which is not a backhanded compliment — her comedy is inseparable from her method. Each book takes a scientific subject that is either taboo, gruesome, or both, investigates it with genuine rigor (she reads the primary literature, interviews the researchers, goes to the labs and the test sites), and reports it with a deadpan wit that makes the material both more accessible and more affecting than a straight science account would be.
Stiff (2003) is her debut and still her best-known book: what happens to human bodies donated to science. The range is comprehensive — crash testing, surgical training, forensic investigation, body farms — and the tone walks a line between comedy and genuine respect for the people who donate their bodies and the researchers who use them. Packing for Mars (2010) investigates the actual science of sending humans into space: what zero gravity does to the body, how astronauts eat and sleep and manage bodily functions, the psychology of confinement. Gulp (2013) traces the digestive tract from mouth to the other end with the same exhaustive curiosity.
Her books are popular science in the best sense: they make readers care about the science by making them laugh at the research process, and the laughter doesn’t diminish the substance.
