the butterfly effect


the butterfly effect

The idea that a small change, action, or event can cause much larger one elsewhere or in the future through a chain reaction. An allusion to chaos theory, popularized by the notion that a butterfly flapping its wings in one part of the world might cause a tornado many miles away. It was basically the butterfly effect that led me to this life: My haphazard decision to study Irish literature in college in Canada led me to do a master's degree in Dublin, which led me to an internship for an Irish publisher, which led me to be friends with a co-worker there, who introduced me to the woman who would eventually be my wife. The government's decision to deregulate the market created a butterfly effect that eventually produced the worst economic meltdown since the Great Depression.See also: butterfly, effect

the butterfly effect

the phenomenon whereby a minute localized change in a complex system can have large effects elsewhere. The expression comes from chaos theory. In 1979 , Edward N.
