A chaotic washing machine? This is just what Goldstar Co. created back in 1993. It was the world's first consumer product to exploit "chaos theory", which holds that there are identifiable and predictable movements in nonlinear systems. This washing machine is supposed to produce cleaner and less tangled clothes. The key to the chaotic motion is a small pulsator (which stirs the water) that rises and falls randomly as the main pulsator rotates. When released to the world market, it was expected to push Goldstar's share of the annual 1.5-million-unit washing machine market to 40% in 1993, compared to 39% for Samsung and 21% for Daewoo (Goldstar's major competitors). However, marketing is fierce in South Korea and Daewoo argues that Goldstar "was not the first" to commercialize chaos theory. Daewoo also built a "bubble machine" in 1990 which also used chaos theory that was the result of "fuzzy logic circuits." Fuzzy circuits make choices between zero and one, and between true and false. These factors control the amount of bubbles, the turbulence of the machine, and even the wobble of the machine. It is clear that chaos theory has not gone unnoticed in today's consumer world market.
