  We study the asymptotic behavior of a singular potential, and discuss the
self-consistency condition for the spherical symmetric Klein-Gordon equation.
In our view, gravity and the weak force are subsidiary, derived from
electricity. Particularly, $SU(2)_L\times U(1)$ unification is derived from the
$L^2$ normalizability condition, without assuming a phase transition. A
possible origin of the Higgs mechanism is proposed. Each particle pair of the
standard model is associated with the corresponding asymptotic expansion of an
eigen function.
  Next we consider the meaning of internal and external degrees of freedom for
a 2 body problem, and find a complex U(1) phase of spins, which can not reduce
to the local motion of an external observer. These degrees of freedom are
inherent to the Poincar\'{e} group, and can be expressed in terms of asymmetric
spinor representations. We try to derive all gauge fields via this
nonintegrable complex U(1) phase. As a spin-off, supersymmetry is regarded as a
kind of Mach's principle for spinning frames-or the Ptolemaic (geocentric)
theory to confuse a rotating frame with an inertial frame.
  Furthermore, we review classical experimental backgrounds for general
relativity, and discuss possible solutions for paradoxes in quantum gravity.
  Taking angular momentums into account to improve above discussions, we can
explain the smallness of neutrino mass without assuming the see-saw mechanism.
A natural geometric interpretation of the quark flavor mixing angle is added in
the Conclusion.
