Why NonLinear Physics?

• Everything is Nonlinear– Macro Systems– Gauge Theory, General Relativity

• Qualitative Differences from Linear Case– Chaos / Fractals– Solitons– Self-Organization / Complexity

History

• Rayleigh-Benard: Patterns

• Russell: Soliton Waves

• Poincare: 3-Body Problem

• Von Neumann: Cellular Automata

• Lorenz: Weather Model

• Mandelbrot: Fractals

• Prigogine: Brusselator

Recent Interests

• Statistical Mechanics– Ergodic Problem

• Complexity– Turbulence / Noises– Life

• Natural Laws As Codes– S. Wolfram, “A New Kind od Science”
