All, or any,
In the emergence literature that I am reading, one of the positions is that
a system is emergent, if, and only if, the only way to "compute it" is with
an ABM.

> I want to move on to the question of where math is effective. Previously,
I wondered about the existence of domains where short logical implications
were reliable but long chains of logical implications may start to be
ineffective. In a sense this is true of any chaotic system, such as
weather. We can now predict weather fairly well for the short term but not
for the long term because we cannot measure the initial conditions to the
required degree of precision (as even arbitrarily small changes now can
cause big changes in future states). It is posible that weather is
mathematically determined, say perfectly described by some chaotic system
and yet math itself would be only of limited use in predicting weather?
