Body Fluids in Forensic Science
The term body fluid is used in a forensic science context to refer to items of biological evidence. The term is a historical one whose meaning has been expanded due to the discovery of the evidential significance of various biological materials. Body fluid therefore refers to not only to typical body liquids such as blood or semen, but to any item of trace evidence with a biological origin, including hair, bone, teeth, faeces and skin or muscle tissue.

—Laurence Sterne (1713–1768)
“What happened at Hiroshima was not only that a scientific breakthrough ... had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.”
