论文摘要
即使在今天，熵的概念也被许多人认为是晦涩难懂的。主要的困难是从根本上分析的，这是由于该概念的主观性和人类中心主义阻碍了我们有足够距离接受它的概念。但是，有人指出，某些演示或某些先入为主的想法缺乏连贯性无济于事。它们是三种：1）公理热力学； 2）某些悖论的解决方案不一致； 3）物理学家不愿对信息理论提供的简化。本文的目的是通过关注理论的结构，什么是基础，思想如何表达，专注于它们的一致性和经济，以什么是基础，思想表达方式，表达方式是什么，以一种教学的方式研究这些观点。它展示了如何在信息理论的帮助下以更一致和经济的方式引入熵，从一开始就考虑到其主观性质，最终允许更直观的理解。
Even today, the concept of entropy is perceived by many as quite obscure. The main difficulty is analyzed as being fundamentally due to the subjectivity and anthropocentrism of the concept that prevent us to have a sufficient distance to embrace it. However, it is pointed out that the lack of coherence of certain presentations or certain preconceived ideas do not help. They are of three kinds : 1) axiomatic thermodynamics; 2) inconsistent solutions of certain paradoxes; 3) reluctance of physicists to the simplification provided by information theory. The purpose of this paper is to examine these points in a didactic way by paying attention to the structure of the theory, what are the foundations, how ideas articulate, with a peculiar focus on their consistency and economy. It is shown how entropy can be introduced in a more consistent and economical manner with the help of information theory, which from the start takes into account its subjective nature, finally allowing a more intuitive understanding.
