<i>Seeking the Small Silent Type</i><p>

<HR>
One of the great breakthroughs in physics of the past decade has been the
 evidence for neutrino mass from neutrino oscillation experiments.  However,
 incorporating these tiny masses into the Standard Model is not
 straightforward.  Many extensions which include neutrino mass also introduce
 "sterile" neutrino partners.  These neutrinos do not interact via the
 strong, electromagnetic OR weak interaction.  But they may participate in
 neutrino oscillations.  This talk considers the motivation and impact of
 sterile neutrino models.  It then focuses on the MiniBooNE experiment, which
 is presently taking data and which may shed light on the question.
