The expectation value of the momentum of bound states in atoms should
be zero. That means that the integral of Ebsi(r)*d Ebsi(r)/dx over the
whole space should be zero and so for y and z.  Mathematically how
this is always satisfied ? I.e, What ensures the validity of this

If one's son's were interested in perusing a college career in Physics,
would one's son be well servers by learning UNIX?  Any particular favour
of UNIX?
Thanks for your time,

"The Scarcity of Life Bearing Planets"
    There is considerable interest in the possibility that there may be a
large number of planets in our galaxy that are suitable for life. In the
hope that there may be intelligent life on planets lying within a reasonable

There is an amusing way to relate the Standard Model families to a
(1,3) geometric system. Consider dt, dx, dy, dz and then put charges:
dt is to be colour neutral, electric +1
dx, dy, dz are to be coloured (r,g,b respectively, say) and electric

"Do Virtual Photons Exist?"
    The Aether was original conceived as a means of explaining "forces
acting at a distance" (i.e.- electric, magnetic, gravitation, et al). When
the idea of the classical Aether was abandoned early in the century, there

Can somebody explain in simple words
why the electroweak unification is described by an
ANGLE? What is the geometrical representation
where this angle appears? (Or are there several of them?)
