Abstract

By analyzing the establishment of magnetic medium thermodynamics，we illustrate how physics describes the universe. Firstly，we invent some abstract concepts and establish operation rules in between. Then，we use those concepts and operation rules to bridge the known experimental results and the new experimental predictions. Some fundamental physical quantities are in general difficult to directly measure in experiments.

Key words： thermodynamics; magnetic medium; fundamental quantity; immeasurability
