Reduction/Vollmer: Def Entropy: the number of microstates that could realize the present macrostate. - Def Pressure: average pulse to transfer the moving molecules on a wall - reduction: e.g. the terms of the phenomenological thermodynamics are defined by concepts of molecular mechanics and thus reduced to this. VsReductionism: in simple language contradictions can still be formulated - then why reduction?
Reductio /Vollmer: if system S2 is developed from system S1, then would theory T2, logically imply theory T1 - but if T1 or T2 are still faulty, it is unlikely that there is an entailment relation between them.
