    I took a look and it occurred to me that the 20 euro note displays the graphic emblem of a bridge, and the bridge idea is the theme of Maldacena's talk.

    In his case the bridge he wants to discuss is the conjectured equivalence between two kinds of mathematical theory. One on bulk (for a universe which apparently unlike ours has negative cosmo constant) and the other on boundary--a field theory on a screen of one less dimension.

    And the bridge emerges from its reflection. (Saying "the bridge reflects in water" is not so exciting.)
