Deterministic Description


Classical Mechanics:
I know forces and initial conditions. I want to predict the evolution. (F=ma)
Quantum Mechanics:
The problem is the same, but stated differently: I want to know the evolution of wave function . ($i\hbar\,\partial\Psi/\partial t= H \Psi$)

Problems with classical and quantum mechanics:

Need to know initial conditions exactly (Bradbury's butterfly)
Classical mechanics can not solve three body problem exactly[*]--even more difficult with more particles!

Is the problem of Statistical Thermodynamics hopeless? NO!
