Abstract
Non-linear refers to the independent variable and the variable are not a linear relationship ,but rather into a curve and the parabolic curve or can not be quantitatively。As the chaotic state of early universe, this relationship is called non-linear relationship. This article describes the main branches and there’s history of the non-linear physics. Then simulation some non-linear equations by computer, and also reviewed some of the latest applications of non-linear physics. At last a I prospect the future of the nonlinear physics.
KEY WORDS: Non-linear; chaos ; fractal ;soliton
