      Sveiki,

      įdomi, sudėtinga ir galinga tema. Pradžiai galiu pacituoti, ką rašo apie
      informaciją "Oxford Dictionary of Computing" (man buvo įdomu). Jie labai
      sieja informaciją su neapibrėžtumo (netikrumo) sumažinimu.

      Cituoju, kai ką sutrumpindamas:

      "Generally, information is whatever is capable of causing a human mind
      to change its opinion about the current state of the real world.
      Formally, and especially in science and engineering, information is
      whatever contributes to a reduction in the uncertainty of the state of a
      system; in this case, uncertainty is usually expressed in an
      objectively measurable form. Commonly, this is done by means of
      Shannon's enthropy.

      Information must be distinguished from any medium that is capable of
      carrying it. The information content of any physical objects, or logical
      data, cannot be measured or discussed until it is known what range of
      possibilities existed before and after they were received. The
      information lies in the reduction in uncertainty resulting from the
      receipt of the objects or the data, and not in the size or complexity of
      the objects or data themselves. Questions of the form, function, and
      semantic import of data are only relevant to information inasmuch as
      they contribute to the reduction of uncertainty. If an identical
      memorandum is received twice, it does not convey twice the information
      that its first occurrence conveyed ...

      The extent to which information is used as an economic commodity is one
      of the defining characteristics of the "post-industrial" society, hence
      the phrase "the information society"."

      Taigi, atrodo, šiame straipsnyje informacija būtinai siejama su žmonėmis
      ir jų protu. O kai žmonių nebuvo? Tada informacijos irgi nebuvo?

      Gyvūnai ir augalai juk irgi naudojasi informacija ir ją netgi perduoda.
      O negyvoji gamta?

      Tilte, deja, nedalyvausiu, tai nors tiek bandau prisidėti. Sėkmės visiems
