人们从认识物质到认识能量,进而认识并研究和运用信息是实践和认识上的一次飞跃。“信息”这个词的性质有点象“数”这个概念,它既不同于任何具体事物,又不能把它与具体事物分开。从广义上说,信息是人类感官所能感知的一切有意义的东西。信息是事物存在的方式或运动状态,以及这种方式或状态的直接或间接的表述。
It is a great leap in practice and cognition for people to understand and study and use information from understanding matter to understanding energy. The nature of the word “information” is somewhat like the notion of “number,” which is different from any concrete thing, and can not separate it from a concrete thing. In a broad sense, information is everything that human senses can sense. Information is the way in which things exist or the state of movement, and the direct or indirect expression of that way or state.
