Kniga posvyashchena novoy sinteticheskoy nauchnoy distsipline - fizicheskoy informatike: razrabotke i primeneniyu informatsionnykh metodov issledovaniya fizicheskikh sistem: polucheniyu otsenok, informatsionnykh ogranicheniy i fizicheskikh sledstviy. Informatsionnymi kharakteristikami fizicheskikh sistem yavlyayutsya: informatsionnaya entropiya - kharakteristika fizicheskikh velichin i sostoyaniy kvantovykh sistem, mera slozhnosti sistem, informatsionnaya divergentsiya, sovmestnaya informatsionnaya entropiya - kharakteristika unitarnykh preobrazovaniy, informatsiya svyazi - kharakteristika vzaimodeystviya stseplennykh (zaputannykh) sistem. Polucheny otsenki ob"ema informatsii v prostykh fizicheskikh sistemakh (fundamental'nykh i elementarnykh chastitsakh, atomakh, molekulakh, ...) i v kosmologicheskikh ob"ektakh (zvezdakh, chernykh dyrakh, ..., galaktikakh, Vselennoy). Privedena otsenka massy nachal'nykh neodnorodnostey Vselennoy. Otkryty novyy klass kosmologicheskikh ob"ektov: optimal'nye chernye dyry, novyy vid fundamental'nykh vzaimodeystviy: informatsionnoe vzaimodeystvie. Dany otsenki ob"ema informatsii v aminokislotakh, azotistykh osnovaniyakh, pokazano, chto zhizn' eto effektivnyy sposob formirovaniya klassicheskoy informatsii. Sformulirovany informatsionnye osnovy fiziki.
