In chemical kinetics, the reaction half-life is the time needed for half of a reactant in a chemical reaction to be depleted. It is the same as the nuclear half-life involved in nuclear decay, which is a first-order reaction.
Famous quotes containing the words reaction and/or life:
“The excessive increase of anything often causes a reaction in the opposite direction.”
—Plato (c. 427–347 B.C.)
“The theater, which is in no thing, but makes use of everything—gestures, sounds, words, screams, light, darkness—rediscovers itself at precisely the point where the mind requires a language to express its manifestations.... To break through language in order to touch life is to create or recreate the theatre.”
—Antonin Artaud (1896–1948)
