  • I actually first started thinking about information as a possible glimmer of an idea for a subject

  • for a book when I was working on Chaos, that's when I first heard about it. And it was strange.

  • It was strange to hear about information theory as a scientific subject of study from a bunch

  • of physicists who were working on chaos theory. I mean, they were analyzing a physical system.

  • In fact, it was chaos in water dripping from a tap, the chaos of a dripping faucet. And

  • they were analyzing it in terms of this thing called information theory, as invented by

  • Claude Shannon at Bell Labs in 1948. And I remember thinking there's something magical

  • about that, but also something kind of weird about it. Information is so abstract. We know

  • that there is such a thing as information devoid of meaning, information as an abstract

  • concept of great use, more than great use, of fantastic power for engineers and scientists.

  • For Claude Shannon to create his theory of information, he very explicitly had to announce

  • that he was thinking of information not in the everyday way we use the word, not as news

  • or gossip or anything that was particularly useful, but as something abstract.

  • A string of bits is information, and it doesn't matter whether those string of bits represent

  • something true or false, and for that matter it doesn't matter whether the string of bits

  • represents something meaningful or meaningless. In fact, from the point of view of an electrical

  • engineer who believes in information theory, a string of random bits carries more information

  • than an orderly string of bits, because the orderly string of bits, let's say alternating

  • ones and zeroes, or let's say not quite as orderly, a string of English text, has organization

  • in it and the organization allows you to predict what the next bit in a given message is going

  • to be. And because you can predict it, it's not as surprising. And because it has less

  • surprise, it carries less information. There's one of the sort of paradoxes of information

  • theory, that because information is surprise it's associated with disorder and randomness.

  • All of this is very abstract. It's useful to scientists. It lies in the foundations

  • of the information-based technological world that we all enjoy. But it's also not satisfactory.

  • I think we as humans tend to feel that this view of information as something devoid of

  • meaning is unfriendly. It's hellish. It's scary. It's connected with our sense that

  • we're deluged by a flood of meaningless tweets and blogs and the hall of mirrors sensation

  • of impostors, the false and true intermingling. We may feel that that's what we get when we

  • start to treat information as something that is not necessarily meaningful because as humans

  • what we care about is the meaning.
