Teoría de la información
La teoría de la información es una disciplina matemática aplicada que se ocupa de cuánta información se puede colocar en un medio dado, usando cualquier conjunto particular de símbolos.
Una gran cantidad de inventos han surgido de la teoría de la información. Incluyen nuevos tipos de medios ópticos, compresión de datos sin pérdida (.zip, .gz, .tar) y con pérdida (.mp3, .jpeg), radio celular (telefonía móvil), y la transmisión y recepción de servicios de red a altas velocidades. La Wikipedia tiene una gran serie de artículos interrelacionados que describen la teoría de la información en detalle.
Proceso
The chief interest of information theory to creation science has to do with:
- How much information can reside in a single molecule of DNA, and
- Whether any of that information could have assembled itself through chance alone.
Information theory can certainly address the first question. But it can address the second only indirectly. Information theory concerns itself primarily with efficiency of information storage and not with information authorship. That said, information theory can tell us that the quantity of information required for life is vast (and give a fair estimate as to how vast). From that one can conclude that the probability of reproducing that information accurately and keeping "information entropy" to a minimum is exceedingly low--and therein lies the problem for concepts such as abiogenesis. Francis H. Crick and Leslie E. Orgel invented their alternative life-origin theory of directed panspermia in direct recognition of the tremendous problem of how such a vast quantity of information could self-assemble.
