Define any property of interest. Eg., O = "reacting with oxygen"

S is a simulation of O iff there is an inferential process, P, by which properties of O can be estimated from P(S) st. S does not implement O

Eg., "A video game is a simulation of a fire burning if, by playing that game, I can determine how long the fire will burn w/o there being any fire involved"

S is an emulation model of O iff ...as-above.. S implements O (eg., "burning down a dollhouse to model burning down a real house").
