Although it may be possible for an electron to be
"at rest", that concept violates the uncertainty
principle. Free electrons jump from atom to atom
but they are never in a fixed position until they
are measured in that fixed position in which case,
they give up their velocity/momentum as an unknown.
Whoever first said, "One cannot have one's cake
and eat it too." apparently understood the
uncertainty principle. :-)

Then I am as uncertain about the uncertainty principle
as I am with the uncertainty Richard is projecting with his posts.
