  The $\Theta^+$ Pentaquark is a Very narrow $\Gamma \approx 1$ MeV
  KN Resonance. Why do some experiments see it and others do not? The lowest
quark configuration that can describe it is exotic $uudd \bar s$.
  Why have no exotics been seen before?
  Is this the beginning of a new spectroscopy? Can it help toteach us about How
QCD makes hadrons from quarks and gluons?
