There are presently three experimental indications of neutrino oscillations from solar, atmospheric, and the LSND neutrino experiments. In the near future, these indications will be checked using terrestrial neutrino beams. At Fermilab, the Minos and MiniBooNE experiments will make definitive explorations of the atmospheric and LSND results respectively. Studies of a future &ngr;-factory program using a muon storage ring show that such a facility would allow measurements of other neutrino mixing parameters, the neutrino mass hierarchy, and possibly CP violations. ©2000 American Institute of Physics.
