The term chaos is from the late 14c., "gaping void; empty, immeasurable space," from Old French chaos (14c.) or directly from Latin chaos, from Greek khaos "abyss, that which gapes wide open, that which is vast and empty," from *khnwos.
Chaos can be a science of surprises and the uncontrollable. Nature is a good example. The difference between order and disorder. What we see as order another may see as disorder. Creativity and innnovation enable order. Arise from the chaos of the day.
Chaos of events, veracity in nature, stranger than fiction
