Re: [asa] M-M experiment

Jack's already given some references. Signhificant variations on the
classical M-M expt are Kennedy Thorndike (with unequal arms, which with
extended observations can rule out explanations in terms of the Fitzgerald
contraction alone) & use of sunlight or starlight as a source. I don't
think having an interfermometer with non-perpendicular or vertical arms
would add anything. The latter setup would have problems with additional
strains in the vertical arm.
