There is a fundamental terminology conflict which has been discussed 
before in this forum.    (02)

I reside in a school of information technology and engineering. 
Among engineers and applied mathematicians, a model is a 
representation, usually mathematical, of some system or object or 
process, that can be used to answer questions about the system or 
object or process.  Here is the correspondence:    (03)

   Engineer's terminology              Logician's terminology    (04)

  Model = set of equations                Set of axioms    (05)

  Realization of a simulation             Model
    of the equations    (06)

When I'm not carefully policing my use of terminology, I tend to talk 
like an engineer, because that's the community I inhabit.    (07)
