从磁介质热力学领悟基本物理量的不可测量性

Understanding the importance of immeasurability of fundamental physical quantities via magnetic media thermodynamics

通过解析磁介质热力学的理论结构,说明物理学认识世界的理论方法是,首先假设一些抽象的概念并建立运算法则,然后这些概念及其运算法则建立起已知实验结果到新的实验预言之间的关系.一般来说,一些基本物理量难以测量.

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.
