1. Front side of postcard from John Wheeler, with cartoon illustrations of some of his contributions to physics, including being an observer within the universe vs being a participant in the dynamics of the universe; a naked singularity vs a black hole; and how to sew together 3-spaces (elements of superspace) into a 4 dimensional spacetime.
