信息力学
Information Mechanics
摘要:
尽管信息作为一个概念在科学中被广泛使用,但我们还没有发展出一个清晰简洁的科学定义。本文的目的是奠定一个新的理论基础,有关力学的信息及其密切关系的工作过程。它主要是为了更好地理解什么是信息。我们发现,像熵一样,信息也是一个状态变量,它们的值都是令人惊讶的上下文。相反,与流行的观点相反,我们发现信息不是负熵。然而,与熵不同的是,信息既可以是正的,也可以是负的。我们进一步发现,它是可以考虑的通信过程作为一个工作过程,香农熵是只适用于统计分布的建模。从广义上讲,信息似乎可以存在于任何系统中,甚至是平衡的热力学系统。令人惊讶的是,一个热力学系统所能做的机械功的量,与相应的可用信息直接相关。如果系统没有相应的信息,不管它包含多少能量,它都不能做功。根据我们提出的理论,读者将清楚地看到,信息是自然存在于我们宇宙中的内在属性,而不是抽象的人类概念。
英文摘要:
Despite the wide usage of information as a concept in science, we have yet to develop a clear & concise scientific definition. This paper is aimed at laying the foundations for a new theory concerning the mechanics of information alongside its intimate relationship with working processes. Principally it aims to provide a better understanding of what information is. We find that like entropy, information is also a state variable, and both their values are surprisingly contextual. Conversely, contrary to popular belief, we find that information is not negative entropy. However, unlike entropy, information can be both positive and negative. We further find that it is possible to consider a communications process as a working process and that Shannon's entropy is only applicable to the modelling of statistical distributions. In extension, it appears that information could exist within any system, even thermodynamic systems at equilibrium. Surprisingly, the amount of mechanical work a thermodynamic system can do directly relates to the appropriate corresponding information available. If the system does not have corresponding information, it can do no work irrespective of how much energy it may contain. Following the theory we present, it will become evident to the reader that information is an intrinsic property which exists naturally within our universe, and not an abstract human notion.
