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.
It is a ket vector, but i don't think he refers to it as a bra vector but instead introduces the notational convention as "bra" instead of bra-ket notation. "Nothing that a man on a galloping horse would notice" as we say in Ireland.
Chris Fields you are a gift! Thanks
Thank youuuu 🙏🏾

At 16:00, isn't |q> a ket, rather than a bra?
