<br>
The hadronic contributions to the anomalous magnetic moment of the
</tt> <tt><br>
muon are an interesting challenge for lattice QCD, especially
given a <br>
persistent discrepancy between theory and experiment. We have <br>
calculated the leading-order hadronic contribution using lattice
QCD. <br>
Our focus has been on establishing what is required for a well-<br>
controlled first-principles calculation. This is the first
calculation<br>
with dynamical fermions to examine lattice artifacts, finite-size
effects<br>
and disconnected diagrams, essentially all the major sources of
error. <br>
We have also studied the quark mass dependence with calculations
at pion<br>
masses ranging from 650 MeV down to 270 MeV. I will discuss a bit
of the <br>
relevant phenomenology and then present our results. </tt>
