it's just a ideal concept. like poisson. there's no real poisson.

consider tossing a coin. if your model includes the force of tossing it, trajectory, air dynamics, weight of the coin, height, etc, then you can determine which side it will be. So "randomness" is an ideal concept, everything in real-life is, to some extent, psudo-random... which is deterministic.

man, it's still deterministic, just that the model is very complicated.... :) － icky 　2007-09-25 09:46 (0 bytes , 348reads )
everything is deterministic. only difference is how complicated the generator is － simon 　2007-09-25 14:35 (42 bytes , 518reads )
yes, if everything is deterministic, how does the random come from? － icky 　2007-09-25 16:57 (32 bytes , 409reads )
