Thermodynamics

This category begins with systems, exchanges, energy and entropy, then develops accessibility, equilibrium representations, potentials and response functions. Later pages address cycles, low-temperature assumptions, phase coexistence, statistical preparations, irreversible boundaries and stochastic protocols. Continuum heat and interacting equilibrium preparations retain their own specified assumptions. The mathematical companions supply the ordered, geometric, analytic and statistical constructions used in these conditional physical deductions.

Each main page introduces the objects and assumptions needed for its results, with links to the prerequisites used in the exposition. Its examples companion gives concrete calculations, limiting cases or counterexamples that clarify those hypotheses. Follow prerequisite links when a definition or earlier result is needed, and read the stated scope alongside each conclusion. Local statements distinguish assumptions from deductions and keep the conventions used in calculations visible. The page list below provides entry points into the subject; the order follows the planned progression from foundational definitions to the later applications.
