> brain and physics are very deterministic
Not to get too much into the 'quantum woo' territory, but my naive understanding is that the physics is only somewhat deterministic, b/c non-deterministic quantum events can have macroscopic effects?
Say you decide for whether you'll eat a dinner, if a particle with half-time of 1 second will split within the next second.
This you wouldn't be able to predict, even if you knew momenta of all particles within your local light-cone (of 1 light-second), no?
(a variation of the Schroedinger's cat)
