One day in late 2004, television art director Karen Steward visited the penthouse floor of a glass office building in Los Angeles to sit down with UCLA epidemiologist Sally Blower and the half dozen members of Blower's Disease Modeling Group and talk about television. Steward was enlisting Blower's scientific expertise for the third episode of the CBS drama NUMB3RS, in which an FBI agent's brother uses mathematical models to determine the origin of a mysterious outbreak of Spanish flu.
