Query: Neutrino Oscillations. Theory and Experiment   The theoretical schemes on neutrino oscillations are considered. The
experimental data on neutrino oscillations from Super-Kamiokande (Japan) and
SNO (Kanada) are given. Comparison of these data with theoretical schemes is
done. Conclusion is made that the experimental data have confirmed the scheme
only with transitions (oscillations) between aromatic $\nu_e, \nu_\mu,
\nu_\tau$ neutrinos with maximal mixing angles.
