Hopelessness at prediction is not at all the same thing as lack of 
precision or paucity of theoretical foundations.  If the dynamics are 
highly nonlinear then prediction is hopeless regardless of how 
well-understood the system is or how precisely things are stated 
(given that initial conditions can never be specified with absolute 
precision).    (02)
