Thermodynamic Theory. Please get alive. Cars travel along streets,
people walk along the pavement, neither of them suffers from congestion
related drop, neither knows about "Thermodynamics".

I once was told a VERY basic wisdom of engineering. "What cannot be
achieved by a simple means can neither be achieved by a sopisticated means".

So networking should be done by simple, well understood mechanisms. I
don't see a real use for overcomplicated calculus. Particularly when the
models are not really close to reality.
