                                            Resum

    We consider the contribution to the entropy from the fluctuations
of a
    scalar field in the background of a curved time-independent
metric. To
 account for the curvature of space, we postulate a position-dependent
cutoff
       that depends on energy. With this cutoff, we calculate the
scalar
  contribution in a background anti-de Sitter space, the exterior of a
black
  hole, and de Sitter space.In all cases, we find results that can be
simply
   interpreted in terms of local energy and proper volume, yielding
insight
                    into why a theory appears to be holographic.
