Title:     Mass, Mixing, and the Neutrino Renaissance

Abstract: The Sudbury Neutrino Observatory (SNO) experiment has produced some of the most important results in physics of the last ten years. SNO data have been used to solve the solar neutrino problem and to conclusively prove that neutrinos undergo flavour change thus demonstrating that neutrinos have mass. These measurements require a fundamental change to the standard model of particle physics and have been at the forefront of the current surge of activity in neutrino physics.

A bief introduction to the standard model of particle physics will be given with emphasis placed on the role of the neutrino and its properties. An historical description outlining the development of our knowledge of neutrino properties will be provided.

The SNO detector and calibration procedures will be described in detail along with presentation of the latest physics results from the complete salt-phase data set. The impact of these results will be discussed in the context of the solar neutrino problem, in terms of currently favoured neutrino models, and in conjunction with results from other neutrino experiments.

The final portion of the talk will explore the future of neutrino physics with focus centred on experiments that can significantly improve our understanding of neutinos and their properties.
