Reply to Onar:
My field, "Network Thermodynamics" is all about computer models of open
thermodynamic systems. In any network model of a real system, the constant
flow of energy THROUGH the system can be modeled by a source. The WHOLE
network, source plus the rest of the system, through which the flows supplied by
the source go, are governed by one of the most powerful ideas in modern
science: "Tellegen's Theorem" which is a purely topolocical statement based on
the application of well accepted conservation laws. From this theorem, most of
what we know about dynamics systems readily follows. In addition, we have
demonstrated a metric for the energy or entropy space in which these systems
sit. Now, the computer MODEL itself can also be dealt with this way as the
computer, as a sophisticated network, carries out the simulation. HOEWEVER,
the relationship between the thermodynamics of the system being simulated and
the thermodynamics of the computer doing tghe simulation is of no consequence.
I assume you agree, but wanted to be sure I was understanding your last post.
