Three Neutrino Flavors are Enough
  It is shown that it is possible to account for all three experimental indications for neutrino oscillations with just three neutrino flavors. In particular, we suggest that the solar and atmospheric neutrino anomalies are to be explained by the same mass difference and mixing. Possible implications and future tests of the resulting mass-mixing pattern are given.
