metaphor of chaos
Chaos: When the
present determines the future, but the approximate present does not
approximately determine the future.
Chaos theory is a branch of mathematics focusing on the behavior of dynamical
systems that are highly sensitive to initial conditions. "Chaos" is an
interdisciplinary theory stating that within the apparent randomness of chaotic
complex systems, there are underlying patterns, constant feedback loops,
repetition, self-similarity, fractals, self-organization, and reliance on
programming at the initial point known as sensitive dependence on initial
conditions. The butterfly effect describes how a small change in one state of a
deterministic nonlinear system can result in large differences in a later state,
e.g. a butterfly flapping its wings in Brazil can cause a hurricane in Texas.
Chaotic behavior exists in many natural systems, such as weather and climate. It
also occurs spontaneously in some systems with artificial components, such as
road traffic. Chaos theory has applications in several disciplines, including
meteorology, anthropology, sociology, physics, environmental science, computer
science, engineering, economics, biology, ecology, and philosophy. The theory
formed the basis for such fields of study as complex dynamical systems, edge of
chaos theory, and self-assembly processes.
Chaos theory concerns deterministic systems whose behavior can in principle be
predicted. Chaotic systems are predictable for a while and then 'appear' to
become random. In chaotic systems, the uncertainty in a forecast increases
exponentially with elapsed time.
