Query: Entropy and its discontents: A note on definitions   The routine definitions of both entropy, and differential entropy show
inconsistencies that make them not reciprocally coherent. We propose a few
possible modifications of these quantities so that 1) they no longer show
incongruities, 2) they go one into the other in a suitable limit as the result
of a renormalization. The properties of the new quantities would slightly
differ from that of the usual entropies in a few other respects
