Chaos Theory

Forty six years ago meteorologist Edward Lorenz inserted numbers of six decimal places (representing current initial conditions) into his computer model and derived weather projections. He later repeated this process but this time rounded off his numbers to three decimal places. To his surprise the weather projections were entirely different. Very very slight change in initial conditions gave entirely different results. Unknowingly, he had just been midwife to the birth of chaos theory and the study of nonlinear systems.
