Listening to the technical term 'holographic, " i wonder if there is any relation between 'holography' as used in this context, and the nineteen seventies' notion of "information spread out over a piece of photographic film by means of interference?'
Profs. t' Hooft and Susskind (in their addresses to laymen) seem to talk about dividing a two-dimensional surface into (Planck-scale) discrete regions, and counting those regions... scarcely what came to mind in the old days, when we heard discussions of holography.
