摘要

熵的概念是从几个形式主义的角度来研究的。回顾了这一现象在经典热力学中的起源。并对其进行了一步一步的明确论证，然后将该公式与香农熵联系起来。解释了量子力学的基本概念，证明了冯-诺依曼熵公式。提出了熵的概念，作为一种衡量系统状态分布可变性的方法，给定一组在系统内部运行一段时间的规则。从信息论的角度来看，一种语言达到了最佳的交流配置。通过这种方式，可以使用相同的熵概念来研究系统和语言。强调了熵教学的重要性，因为这对新技术的发展很有用，例如量子通信。

The entropy of systems

The entropy concept is studied from the perspective of several formalisms. It is reviewed the origins of this in the classical thermodynamics. It also is developed a step-by-step-clearly demonstration about it. After that, it is connected this formula with the entropy of Shannon. Elementary concepts of the quantum mechanics are explained to demonstrate the von Neumann entropy formula. It is proposed the entropy concept as a measure of the variability into the distribution of the states of a system given a set of rules that operate inside it for a while. From the perspective of the information theory, a language reaches a configuration to be optimal for communications. In this way, systems and languages can be studied using the same concept of entropy. It is stressed the importance of the teaching of the entropy because this is useful in the development of new technologies, for example the quantum communications.

期刊介绍： The Revista Mexicana de Física (Rev. Mex. Fis.) publishes original papers of interest to our readers from the physical science com unity. Language may be English or Spanish, however, given the nature of our readers, English is recommended. Articles are classified as follows: Research. Articles reporting original results in physical science. Instrumentation. Articles reporting original contributions on design and construction of scientific instruments. They should present new instruments and techniques oriented to physical science problems solutions. They must also report measurements performed with the described instrument. Reviews. Critical surveys of specific physical science topics in which recent published information is analyzed and discussed. They should be accessible to physics graduate students and non specialists, and provide valuable bibliography to the specialist. Comments. Short papers (four pages maximum) that assess critically papers by others authors previously published in the Revista Mexicana de Física. A comment should state clearly to which paper it refers.
