Is entropy a physical quantity or a conceptual construct?
I'm analyzing irreversible processes in closed systems. The Clausius definition treats it as a concrete thermodynamic coordinate. Yet, Boltzmann's formulation ties it to microstates and information, which seems more abstract. This duality is causing a foundational tension in how I interpret my data and the physical reality it represents.

In both theoretical and experimental work, I've seen entropy function as a tangible, calculable quantity. We measure its changes calorimetrically, making it physically operational in engineering. However, its deepest meaning as a measure of microstate multiplicity or information is indeed a profound conceptual framework. I recommend viewing it as a physical quantity whose full interpretation requires the conceptual construct. This dual perspective is not a weakness but the source of its immense explanatory power across disciplines.
