visualizability

Clausius 'thermodynamic definition of entropy, based as it is ultimately on a certain existence theorem in the theory of differentials, is obviously rather abstract and far removed from visualizability, in spite of the fact that the differential expression under discussion reflects an operational result in steam-power engineer - ing.

ENTROPY MAX JAMMER 1968

In developing his own account of explanatory proof in mathematics he discusses ” and rejects ” a number of initially plausible criteria for explanation, e.g. the (greater degree of) abstractness or generality of a proof, its visualizability, and its genetic aspect that would give rise to the discovery of the result.
