  A basic and inherently simple connection is shown to exist between
superconductivity and superfluidity. It is shown here that the author's
previously derived general equation which agrees well with the superconducting
transition temperatures for the heavy-electron superconductors, metallic
superconductors, oxide supercon- ductors, metallic hydrogen, and neutron stars,
also works well for the superfluid transition temperature of 2.6 mK for liquid
3He. Reasonable estimates are made from 10^-3 K to 10^9K -- a range of 12
orders of magnitude. The same paradigm applies to the superfluid transition
temperature of liquid 4He, but results in a slightly different equation. The
superfluid transition temperature for dilute solutions of 3He in superfluid 4He
is estimated to be ~ 1 to 10mK. This paradigm works well in detail for
metallic, cuprate, and organic superconductors.
