thanks for the example of molecular dynamics-
i guess i would distinguish three sub categories
- representation/ eg a walt dysney cartoon that elicits human response like
the physical phenomenon but the animation does not encode any physics
- emulation- where the representation behaves like the physical phenomenon
but does not encode the same physical assumptions ( eg a computer can
emulate old software but runs on new computer chips and emulates the way the
old chips behaved)
- simulation- where the software system encodes the best scientific laws
available to enable a system to behave like the real phenomenon= many
artificial life systems try to do this
the two examples i gave on stellar evolution and evolution of structure of
the universe are "simulations'= i tried to
find out what category the molecular dynamics animation was\
but couldnt=do you know ?
i suspect that there are texts on these differences between
represenation/emulation/simulation =maybe yasminers can point
us to them

Thank you Roger and Avi, informative and beautiful mterial
adding to this i would suggest
and other similar molecular dynamics simulations
