sin^2 (T) = .23117 +/- .00016
for the Weak mixing angle T, I get:
tan^2(T) = .3007 +/- .0003 ~~ 3/10.

A priori, one would want tan^2(T) to be some simple rational number if the
eigenvalues of the couplings for the Z to the various fermions are to be
rational multiples of each other, as they are for all the other bosons.

The usual anomaly cancellation argument only explains the assignments
to the U(1)_Y hypercharge sector; it doesn't explain why the photon
couplings are rational with relation to each other (i.e. why electric
charge is quantized). These are functions of the weak mixing angle and
could, a' priori, be anything rational or not. Since they're rational,
then the attention is focused on whether the other mass eigenstate
mixture involving the weak mixing angle -- the Z -- has charge
quantization.

The Z charges are quantized if and only if tan^2(T) is rational. The
near coincidence of tan^2(T) to 3/10, then, in this light is interesting.
