The progress in neutrino physics over the past fifteen years has been tremendous: we have learned that neutrinos have mass and change flavor. I will pick out one of the threads of the story-- the measurement of flavor oscillation in neutrinos produced by cosmic ray showers in the atmosphere, and further measurements by long-baseline beam experiments. In this talk, I will review the latest results from atmospheric and long-baseline neutrino experiments, and will discuss how the remaining puzzles can be addressed.
