[Noisebridge-discuss] Philosophy and Computer Language Question

[Gopiballava Flaherty]

How reality is simulated? That's a very broad question. A wind tunnel is a simulation of reality. Google Maps and especially route finding and extra especially route finding with traffic delays is a reality simulation. 

I think most reality simulation tends to be very, very domain specific and tends to ignore huge parts of reality to simplify things (eg: determining trip duration by speed of road, rather than stepping through the car position every second. )

I'd be astonished if more than a tiny handful of reality simulation systems contained within their workings anything that resembles the philosophical concepts you've outlined. 

Thanks,

Process Philosophy states at there are no substantive objects, but that all ‘things’ are functions that process experience into results that become ‘mortal’ in the Creative Advance of time•space.  this is very similar from my recollection of event driven applications.

We have several different formalisms for modeling these; well-known ones, in no particular order, include Petri nets, Lamport's temporal logic of actions, process calculi such as the pi-calculus, and the actor model. There are others as well: http://en.wikipedia.org/wiki/Concurrency_(computer_science)#Theory
