  The last half century of research into the structure, dynamics, and
thermodynamics of simple liquids has revealed a number of approximate
universalities. This paper argues that simple liquids' reduced-coordinate
constant-potential-energy hypersurfaces constitute a quasiuniversal family of
compact Riemannian manifolds parameterized by a single number, from which
follows these liquids' quasiuniversalities.
