话说当年,香农搞出了信息论,与大数学家Von Neumann讨论后来非常著名的“信息熵”的概念。Von Neumann说道:“The theory was in excellent shape, except that he needed a good name for “missing information”. “Why don’t you call it entropy”, “In the first place, a mathematical development very much like yours already exists in Boltzmann’s statistical mechanics, and in the second place, no one understands entropy very well, so in any discussion you will be in a position of advantage.”
