Query: Pressure of Membrane between Walls   For a single membrane of stiffness kappa fluctuating between two planar walls
of distance d, we calculate analytically the proportionality constant in the
pressure law p proportional to T^2/kappa^2 d^3, in very good agreement with
results from Monte Carlo simulations.
